Yes HHS In our institution, that corresponded to ≥34 days. Conceptualization, Validation, There are some limitations to our study. Background: Determining length of stay (LOS) and the attributable costs for hospital admissions are of critical importance for patients (Pts), providers, payers, and hospital management. Prolonged Length-of-stay (PLOS) is associated with increased mortality and other poor outcomes. In this study, we analyzed >85,000 episodes of hospitalization in a tertiary healthcare referral center in Mexico City over a 18-year period, and we found that NLOS and PLOS patients are quite a distinct populations. Bone marrow transplant (OR 18.39 [95% CI 12.50–27.05, p<0.001), complex infectious diseases such as systemic mycoses and parasitoses (OR 4.65 [95% CI 3.40–6.63, p<0.001), and complex abdominal diseases such as intestinal fistula (OR 2.57 [95% CI 1.98–3.32) had the greatest risk for PLOS. Correction: Risk factors associated with prolonged hospital length-of-stay: 18-year retrospective study of hospitalizations in a tertiary healthcare center in Mexico. The binary logistic regression analysis of the discharge diagnoses demonstrated a predominance of complex diseases, such as hematological malignancies, complex infectious and intestinal/abdominal diseases and autoimmune diseases as risk factors for PLOS (Fig 2). The percentage increased from 2.4% in 2000 to 7.6% in 2007, then declined slightly in the ensuing years and remained stable during 2009–2016 with a later peak in 2017. The author(s) received no specific funding for this work. PLOS ONE promises fair, rigorous peer review, PLOS were defined as those above the 95th percentile of length of hospitalization. Conceptualization, e0207203. Increased LOS can sometimes be due difficulties in coordinating a safe and timely discharge plan. HAI can significantly increase the LOS. There are several factors which contribute to an increase in patient length of stay: During each event of hospitalization, patients could be transferred several times to different areas of the hospital depending on their clinical status (e.g. The amount of transfused blood was predictive of in-hospital mortality, with an odds ratio of 1.4 for each unit of blood received. There are two potential explanations for this “weekend effect” at our institution: 1) Hospital staffing (physician to patient ratio) is lower on weekends and, 2) patients with complicated diseases referred from other hospitals (outside Mexico City) are admitted predominantly on weekends. The study derived from an institutional monitoring program to assess LOS during 2016 and was later extended as a retrospective, cross-sectional analysis of all episodes of hospitalization from January 2000 to December 2017. Surgeries occurred in 62.5% of PLOS hospitalizations and in 40.7% of NLOS (p<0.001). Further investigations to identify other presently unaccounted changes in hospital infrastructure, organization and logistics are needed to better characterize this observation. We would like to thank Fermín Alvarez-Hernandez, Head of the Clinical Record and Statistics Department at INCMNSZ for his assistance obtaining our Institution’s databases. The black, vertical, boxplots illustrate the annual adjusted odds ratios (aORs) for prolonged stay of hospitalization (PLOS) using 2000 as the year of reference. .

The black, vertical, boxplots illustrate the annual adjusted odds ratios (aORs) for prolonged stay of hospitalization (PLOS) using 2000 as the year of reference. 2006;7(1):55–65. Background: Hospital length-of-Stay has been traditionally used as a surrogate to evaluate healthcare efficiency, as well as hospital resource utilization. During the study period there was an important reduction in the proportion of elective and urgent surgical events of hospitalization (dark and light gray bars). Hospital Length-Of-Stay (LOS) refers to the total bed-days occupied by a patient during his hospitalization, and it has been used as a traditional surrogate to evaluate efficiency of healthcare, effectiveness of preventive and therapeutic strategies, diagnostic methods, clinical pathways, as well as hospital resource utilization, allocation, and administration[2].  |  Although an initial univariate analysis showed hospitalization in shared room to be a risk factor for PLOS, this effect did not persist after adjusting for socioeconomic level, which frequently determines the type of hospitalization room. We used multinomial logistic regression models to control for age, gender, type of admission, recent hospital discharge, weekday/weekend admission, additional diagnoses, place of residence and socioeconomic status, using inverse probability weights based on diagnosis of admission. A lower mortality among patients with PLOS (4.4%) has been reported in other studies[20]. Further studies describing risk factors associated with mortality in our Institution are underway. Risk of mortality in patients with PLOS increased more than threefold (3.7% vs 13.3%, p<0.001). While this latter group was smaller, it had the greatest proportion of hospitalizations with PLOS (19.5%) (Fig 1, Panel A). -. We sought to describe and compare characteristics of patients with Normal hospital Length-of-Stay (NLOS) and PLOS to identify sociodemographic and disease-specific factors associated with PLOS in a tertiary care institution that attends adults with complicated diseases from all over Mexico. https://doi.org/10.1371/journal.pone.0207203.g001. The median LOS for all hospitalization events was 8 days in 2000, peaked at 10 days in 2006 and 2007 and then declined to 8 days afterwards and up to 2015, when it declined again by one day (B). Roles Younger age, male gender, a lower physician-to-patient ratio, emergency and weekend admissions, surgery, the number of comorbidities, residence outside Mexico City and lower socioeconomic status were associated with PLOS. An explanation for this is difficult. Some degree of malnutrition has been reported in 30–50% of hospitalized patients. We report some key sociodemographic and disease-specific differences in patients with PLOS. However, patients referred from other hospitals (frequently outside Mexico City), with diseases that require more complex diagnostic workup or therapeutic approach. Every hospitalization episode was associated to an individual patient’s institutional registry number. Introduction. Elective hospitalization events for surgical procedures increased the most during the study period. Writing – review & editing, Affiliations Validation, The frequency of PLOS was significantly higher during hospitalization events that required a surgical intervention. In contrast, hospitalizations for solid organ transplantation (aOR 0.10, 95% CI 0.06–0.16), due to common surgical procedures (aOR 0.15, 95% CI 0.11–0.20), disorders of the genital tract (aOR0.22, 95% CI 0.15–0.34) including neoplasms (aOR 0.26, 95% CI 0.17–0.39), thyroid disorders (aOR 0.24, 95% CI 0.11–0.51), among others were associated with a decreased risk of PLOS (Fig 2). In addition, hospitals face lower patient capacities and increased costs. Bone marrow transplant (OR 18.39 [95% CI 12.50-27.05, p<0.001), complex infectious diseases such as systemic mycoses and parasitoses (OR 4.65 [95% CI 3.40-6.63, p<0.001), and complex abdominal diseases such as intestinal fistula (OR 2.57 [95% CI 1.98-3.32) had the greatest risk for PLOS. Our findings could serve to develop a specific model of directed hospital healthcare once these factors are identified at admission and/or during hospitalization. No informed consent was deemed necessary by our institution’s Ethics and Scientific Committees (Institutional Review Board) and the manuscript was evaluated and approved by these committees prior to submission for publication. (B) Annual trends of the distribution of type of hospitalization. To identify the independent effect of pressure ulcers on excess length of stay and control for all observable factors that may also contribute to excess length of stay. NIH Conceptualization, Hence, we sought to describe the frequency of PLOS in a tertiary healthcare referral center located in Mexico City, analyze changes in LOS through time, describe the characteristics of the events of hospitalization associated to PLOS, and identify factors associated with this outcome. This particular population should be further analyzed to dilucidate which specific factors of surgical interventions are associated with PLOS, which could aid in the design of preventive strategies for PLOS and other outcomes (e.g. Briefly, the crude frequency of PLOS increased between 2000 and 2007 from 2.4% to 7.6%, and then decreased the following three years to 5%, and appears to stabilize and vary between 5% to 6% until the end of the study. Weekend admissions, another potentially modifiable risk factor for PLOS, have already been associated with increased risk of PLOS and other poor outcomes (e.g. Moreover, there is an apparent, multiplicative interaction between urgent hospitalizations that require surgical interventions. Diagnoses and surgeries were classified in groups for analysis (55 diagnostic groups and 30 surgical groups). Prolonged length of stay after posterior surgery for cervical spondylotic myelopathy in patients over 65years of age. Available at, Marshall A, Vasilakis C, El-Darzi E. Length of stay-based patient flow models: recent developments and future directions. -, Williams TA, Ho KM, Dobb GJ, Finn JC, Knuiman M, Webb SA, et al. 2005;8(3):213–20. Validation, 3 Assessment tools for the evaluation of nutritional status vary in their ability to predict LOS and morbidity. The percentage increased from 2.4% in 2000 to 7.6% in 2007, then declined slightly in the ensuing years and remained stable during 2009–2016 with a later peak in 2017. Improving and reducing length of stay (LOS) improves financial, operational, and clinical outcomes by decreasing the costs of care for a patient. All data presented in this study originated for electronic health records that are identified by an individual institutional registry and should be managed securely. Fig 3. Funding: The author(s) received no specific funding for this work. Length of stay (LOS) is an important measure of resource utilization as patients with prolonged LOS disproportionately account for the consumption of more hospital resources [].Prolonged LOS, which is defined as inpatient stay that exceeds the expected LOS for a certain procedure [], unnecessarily utilizes hospital beds, contributing to capacity shortage. No, Is the Subject Area "Medical risk factors" applicable to this article? 2011–. At this institution there are 167 hospital beds available for admission, and the annual average of hospitalization events is 4772.4 (SD ± 346.6). We identified several risk factors for PLOS, that can be grouped as modifiable (perhaps preventable) and other non-modifiable, both recognizable at hospital admission. mortality). Question Do fast-track discharge protocols and shorter postoperative length of stay after major inpatient surgery reduce overall surgical episode payments, or are there unintended increased costs because of postdischarge care?. 1 Length of stay (LOS) is an aspect of care that can be costly for most healthcare systems if … Writing – review & editing, Roles There was no significant difference in the increased LOS between different hospital levels. Conclusions: Hospitals benefit from a shorter LOS. mortality). . PLOS were found to have a lower median socioeconomic status in our study, which further accentuates this issue. (B) Annual trends of the distribution of type of hospitalization. The median hospital LOS for all events was 8 days (interquartile range [IQR] 5–14); 8 days for NLOS (IQR 5–13) and 45 days for PLOS (IQR 38–60). Yes The twenty most common diagnoses are shown in Table 2. Additionally, these patients represent a significant economic problem on public health systems and their families. We used as reference “Diseases of the liver, biliary tract and pancreas (K70.0-K79.9, K83.0-K89.9)”, because it was the second largest diagnosis group (N = 6,426) and patients with PLOS and NLOS were equally distributed within this diagnosis group (7.7 vs 7.6%, respectively, p = 0.31). Results showed significantly longer hospital stays for patients with a history of gout compared with those without gout (log length of stay, 1.86 vs 1.72 days, respectively; P =.0278). Yes Introduction Healthcare-associated infections (HAIs) are a major health concern and have substantial effects on morbidity and mortality and increase healthcare costs. No, Is the Subject Area "Mexico" applicable to this article? Materials and methods: Fig 1. The black, dotted line, summarizes the annual median length-of-stay (LOS) in days across time, during the study period. Hospitalized patients who develop a pressure ulcer during their hospital stay are at a greater risk for increased length of stay as compared with patients who do not. Hospital inpatient care makes up nearly one-third of all healthcare expenditures in the United States, and represents a significant impact on the country’s economy. Global Health Expenditure Database. We conducted a retrospective analysis of hospital discharges from January 2000-December 2017 using institutional databases of medical records. Patient length of stay (LOS) is one of the biggest issues facing hospitals today. First Pediatric Outpatient Parenteral Antibiotic Therapy Clinic in Indonesia. The increase varies according to hospital level, region, site of infection, and infected pathogen, and it also varies if the pathogens were multidrug-resistant. https://doi.org/10.1371/journal.pone.0207203.t001. All data were de-identified and fully anonymized before the analysis. These were used to combine patient transfers within the different areas of our hospital (wards, ICU, ED) into a single continuous episode. PLOS has already been described as a risk factor for mortality, and previous studies in Mexico have reported that patients with a LOS >21 days have increased mortality (OR 2.41 [CI 95% 2.30–2.51])[25]. The adjusted risk of PLOS increased between 2000 and 2007, then substantially and continuously decrease afterwards despite a sustained percentage of PLOS episodes after 2008. https://doi.org/10.1371/journal.pone.0207203.g003, https://doi.org/10.1371/journal.pone.0207203.t003. The increased LOS of GI wa… In an adjusted analysis of 129 VA hospitals over 14 years, published in Annals of Internal Medicine in December 2012, researchers found that an intense focus on efficiency led to decreases in both LOS (down 27%) and 30-day readmissions (down 16%) as well as fewer deaths from any cause at 30 and 90 days after admission. We identified 4,427 PLOS events (5.1%) which corresponded to 23.1% of the total bed-days (247,428).

Relationship between gender and risk of PLOS has been scarcely investigated, although female patients have been typically described as having more prolonged LOS [16, 17]. Reducing hospital length of stay (LOS), especially as it relates to avoiding unnecessary hospital-acquired conditions (HACs), is a primary indicator of a hospital’s success in achieving these goals. 10.1093/bja/aeq025 . We compared NLOS and PLOS using descriptive and inferential statistics. https://doi.org/10.1371/journal.pone.0207203.g002. J Clin Neurosci. NLM 2009 Mar;15(3):273-9. doi: 10.1002/lt.21731.

Also, patients receiving care at our institute are expected to have diseases of high-risk for PLOS; thus, it may be challenging to extrapolate our results to other medical institutions in our country. De la Garza-Ramos R, Goodwin CR, Abu-Bonsrah N, Jain A, Miller EK, Neuman BJ, Protopsaltis TS, Passias PG, Sciubba DM. Visualization, One of the best ways to improve a hospital’s financial margin is to reduce the average patient length of stay. During the study period there was an important reduction in the proportion of elective and urgent surgical events of hospitalization (dark and light gray bars). USA.gov. 2010;104(4):459–64. The authors have declared that no competing interests exist. Admission through the ED increased the risk of PLOS in our study, as previously reported elsewhere[19, 20]. PLOS ONE 13(12): e0209944. The operational indicator for hospital LOS is the average length-of-stay, and by this measure patients may be classified as those with a Normal Length-Of-Stay (NLOS) and those with a Prolonged Length-Of-Stay (PLOS). -, Baek H, Cho M, Kim S, Hwang H, Song M, Yoo S. Analysis of length of hospital stay using electronic health records: A statistical and data mining approach. We analyzed 85,904 hospitalization events (1,069,875 bed-days) during the 18-year study period. PLoS One. PLoS One. Overcrowding in emergency departments is a problem in many countries around the world, including the United States and Chile. This could explain the increased risk of PLOS in this population. Odds ratios for PLOS by diagnosis at discharge were adjusted for age, gender, physician-to-patient ratio, type of admission, readmission at 30 days, day of admission (weekday vs weekend), number of additional diagnosis, place of residence and socioeconomic status using multinomial logistic regression models fixing “Diseases of the liver, biliary tract and pancreas (K70.0-K79.9, K83.0-K89.9)” as the reference group. http://apps.who.int/nha/database/Country_Profile/Index/en, World Health Organization. Hospitalization often results in a decline in functioning for older adults due to interactions of aging, disease, and hospital factors. Most of these deaths occurred in the hospital ward, but a greater proportion of patients with PLOS died in the ICU in comparison with NLOS patients (35.0 vs 18.9%, p<0.001). Conceptualization, The HAI caused an increase in stay of 10.4 days. increase length of stay and stall patient flow. The database is completed by both physicians and professionally trained personnel, which decreases codification errors. As hospitals and healthcare systems pinch pennies and look for ways to operate more efficiently, a new report reveals six simple steps they can take to reduce length of stay and increase … Annual frequency of hospitalizations classified as prolonged length-of-stay (PLOS) from 2000–2017. Separately, to identify sociodemographic and clinical factors associated to PLOS controlling for the diagnosis of discharge, we fit a multinomial logistic regression model for PLOS based on the 55 different diagnostic groups. Yes Hospital length-of-Stay has been traditionally used as a surrogate to evaluate healthcare efficiency, as well as hospital resource utilization. We used multiple chained equations to impute missing data with 10 imputations. The adjusted risk of PLOS increased between 2000 and 2007, then substantially and continuously decrease afterwards despite a sustained percentage of PLOS episodes after 2008. eCollection 2020. In: VA Evidence Synthesis Program Evidence Briefs [Internet]. Additionally, these patients represent a significant economic problem on public health systems and their families. Writing – review & editing, Roles Overall, in-hospital crude mortality was 4.2% (n = 3,623). These comprise around 70% of all the hospitalizations, but their distribution differ by groups: 61.9% in PLOS and 72.9% in NLOS; thus, other less frequent diagnoses account for a greater proportion of PLOS events. LOS was considered from the day of hospital admission (regardless of the initial service of admission) to the day of hospital discharge or death (regardless of the service of discharge or death). The black, dotted line, summarizes the annual median length-of-stay (LOS) in days across time, during the study period. By this measure, patients are classified in seven levels (1–7) which are inversely related to the magnitude of subsidy over health expenditure during hospitalization. We generated inverse weights using the predictions of this univariate multinomial model for PLOS. Prolonged Length-of-stay (PLOS) is associated with increased mortality and other poor outcomes. (A) Overall Distribution of PLOS events by type of hospitalization (elective or emergency and surgical and non-surgical). Data Availability: There are ethical limitations on data sharing because the Institutional Ethics and Research Committee of the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, which approved this study, did not approve for public data availability. Patient demographics, associated disease, length of hospital stay, morbidity and mortality were also evaluated. These could serve to develop a specific model of directed hospital healthcare for patients identified as in risk of PLOS. Moreover, the median time for readmission was shorter in PLOS hospitalizations, both for early (11 vs 13 days, p<0.001) and late (201 vs 261 days, p<0.001) readmissions. 2020 Jun 16;13:24. doi: 10.1186/s40545-020-00230-6. Surgical patients represent a considerable percentage of total hospitalizations events and risk factors for PLOS related to surgery have been previously described for several types of surgeries[13, 14]. We compared NLOS and PLOS using descriptive and inferential statistics. Men had a slightly increased risk for PLOS than women (aOR 1.077, 95% CI 1.054–1.101), as well as early readmissions (aOR 1.05, 95% CI 1.02–1.09) and admission on weekends (Table 3). Additionally, these patients represent a significant economic problem on public health systems and their families. (A) The vertical, gray bars represent the annual percentage of hospitalization events classified as PLOS. OBJECTIVETo determine whether a multidisciplinary mobility promotion quality‐improvement (QI) project would increase patient mobility and reduce hospital length of stay (LOS).PATIENTS AND METHODSImplemented using a structured QI model, the project took place between March 1, 2013 and March 1, 2014 on 2 general medicine units in a large academic medical center. Writing – review & editing, Roles eCollection 2018. A higher percentage of patients with an unexpectedly long length of stay (UL-LOS) compared to the national average may indicate shortcomings in patient safety. Objective: To identify the independent effect of pressure ulcers on excess length of stay and control for all observable factors that may also contribute to excess length of stay. While these, and other potentially unaccounted changes in organization occur gradually; we identified that increasing the physician-to-patient ratio, which occurred in February 2008, was associated to a decreased risk of PLOS. We explored the utility of the UL-LOS indicator. Annual frequency of hospitalizations classified…. Such difference highlights the need for strategies to control health expenditure in Mexico and to evaluate healthcare efficiency and resource utilization, particularly, concerning health expenditure on hospitalized patients. Eur J Health Econ. Hospital-related functional decline in older patients and the subsequent harm has dreadful consequences for many patients, and is something we should not tolerate. No, PLOS is a nonprofit 501(c)(3) corporation, #C2354500, based in San Francisco, California, US, https://doi.org/10.1371/journal.pone.0207203, https://doi.org/10.1371/journal.pone.0209944, http://apps.who.int/nha/database/Country_Profile/Index/en. Blood transfusion was predictive of length of postoperative hospital stay and number of complications before discharge. Finally, our analyses are adjusted to multiple factors, which increases the robustness of our results. In particular, being a retrospective, cross-sectional analysis, our study is highly susceptible to different types of bias and confounding. Importantly, we identified potentially modifiable factors associated with PLOS, which in our Institution appear to have contributed importantly to reduce LOS over time. Research has found that patients can be moved four or five times during a hospital stay, often with incomplete notes and no formal handover (Cornwell and others, 2012; Royal College of Physicians, unpublished). (A) The vertical, gray bars represent the annual percentage of hospitalization events classified as PLOS. Overall, this study provides data to guide research models that could culminate in public health policies to assess efficacy of healthcare at other public institutions and/or hospitals and prevent or correct risk factors for PLOS. Emergency department (ED) overcrowding causes problems for patients and staff, including increased waiting times, increased ambulance diversion, increased length of stay, increased medical errors, increased patient mortality, and increased harm to hospitals … No, Is the Subject Area "Surgical and invasive medical procedures" applicable to this article? Visualization, The main diagnosis at hospital discharge or death, was considered the reason for hospitalization. Correction: Risk factors associated with prolonged hospital length-of-stay: 18-year retrospective study of hospitalizations in a tertiary healthcare center in Mexico. The goal of the present study was to evaluate oncology Pts receiving inpatient … Quantitative variables were compared with a Student’s t test or a Mann-Whitney U test, according to their distribution after applying skewness and kurtosis tests for normality. 1-3 Hospital length of stay (HLOS) has been shown to predict functional decline for older adults, with longer HLOS associated with a greater likelihood of decline. Among the non-modifiable risk factors, we found that younger age, male gender, type of admission and hospitalization (specially emergency and surgical admissions), the number of comorbidities, place of residence (outside of Mexico City) and a lower socioeconomic status were associated with an increased risk of PLOS. Yes Recent research suggests that improvements in efficiency during the inpatient stay can lower LOS without increasing unnecessary readmissions. broad scope, and wide readership – a perfect fit for your research every time. The longer a patient stays in the hospital, the greater the risk they will develop a healthcare-acquired infection (HAI) that they can become vulnerable to. Only events that included at least one day of stay in the general hospital wards during their total hospitalization were included in the analysis. Our higher mortality could be explained, partly, by the fact that our study was conducted in a tertiary care referral hospital, included patients admitted from the ED and ICU and that we considered the 95th percentile as a cut-off point to define PLOS. Also, certain diagnosis groups had an increased risk for PLOS, such as bone marrow transplant, fungal and bacterial infections, hematological neoplasms, complex intestinal and abdominal disorders, tuberculosis, and HIV-related infections, among others. This change also led to a progressive decrease in the median LOS, which further supports the robustness of this measure. Ensuring the delivery of appropriate care and treatment is crucial for quality of care; length of stay in hospital may be irrelevant to this process. Evidence Brief: Effectiveness of Intensive Primary Care Programs. These patients are typically admitted in a more critical condition and have a high mortality; we found a mortality of 8.4% for those admitted through the ED vs 3.7% for those admitted directly to the wards (p<0.001). here. Evidence-based information on effects to patients of increased length of hospital stay from hundreds of trustworthy sources for health and social care. Prolonged Length-of-stay (PLOS) is associated with increased mortality and other poor outcomes. Malnourished patients are a population with documented longer length of stay, higher costs, and in-hospital complications [].Malnutrition is common among hospital patients with prevalence estimates between 20 and 50% [].The extant literature provides evidence that malnutrition is associated with increased length in stay and hospital readmission [1, 3,4,5]. Median age at hospitalization was 51-years old (yo) (IQR 35–66). Clipboard, Search History, and several other advanced features are temporarily unavailable. 2018 Dec 21;13(12):e0209944. Russell-Weisz, D., & Hindle, D. (2000). Faced with declining revenue related to changes in Medicare and Medicaid reimbursements, Memorial Hospital at Gulfport knew additional methods of providing more efficient and cost-effective quality care were needed to maintain long-term success. After adjusting for the discharge diagnosis, we identified that age was independently, but weakly associated in an inverse manner with the risk of PLOS (1.2% risk reduction for each increasing year of age, 95%CI 1.1%-1.2%). (2018) Risk factors associated with prolonged hospital length-of-stay: 18-year retrospective study of hospitalizations in a tertiary healthcare center in Mexico. Washington (DC): Department of Veterans Affairs (US); 2011–. https://doi.org/10.1371/journal.pone.0209944 The modifiable risk factors include: physician-to-patient ratio and, potentially, the day of admission (weekday vs weekends). Methodology, Get the latest research from NIH: https://www.nih.gov/coronavirus. Our study was not specifically designed to test these hypotheses, but further studies may confirm this finding. Results: A hospital stay carries a 5.5% risk of an adverse drug reaction, 17.6% risk of infection, and 3.1% risk of ulcer for an average episode, and each additional night in hospital increases the risk by 0.5% for adverse drug reactions, 1.6% for infections, and 0.5% for ulcers. We also identified that emergency hospitalizations that required any type of surgical intervention ("emergency, surgical”) had the highest risk of PLOS in comparison to “elective, non-surgical” events of hospitalization (aOR 5.07, 95% CI 4.84–5.30). Our hospital, a public tertiary healthcare referral center located in Mexico City, is one of the Mexican National Institutes of Health (MNIH) and provides healthcare to adult patients with complex diseases from all over the country. Elective hospitalization events for surgical procedures increased the most during the study period. Effect of length of stay in intensive care unit on hospital and long-term mortality of critically ill adult patients. Distribution of prolonged length of…, Fig 1. Younger age, male gender, a lower physician-to-patient ratio, emergency and weekend admissions, surgery, the number of comorbidities, residence outside Mexico City and lower socioeconomic status were associated with PLOS. Departamento de Infectología, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City, Mexico, 21 Dec 2018: 4-6 HLOS has been decreasing in recent decades. No, Is the Subject Area "Cancer detection and diagnosis" applicable to this article? NLOS patients were defined as those with a LOS <34 days. Setting We used data of 61 Dutch hospitals. • A stay in hospital over 10 days leads to 10 years of muscle ageing for some people who are most at risk (see Section 12 for the evidence). This is the first study analyzing risk factors for PLOS in Mexico and Latin America and herein we provide useful information from a large number of hospitalizations. This classification is similar to others previously published and validated [7]. This site needs JavaScript to work properly. Epub 2016 May 24. PLOS hospitalizations occurred as early readmissions (≤30 days) more frequently than NLOS hospitalizations (33.6 vs 27.9%, p<0.001). Visualization, Methodology, Arch Med Res.

Data curation, High length-of-stay outliers under casemix funding of a remote rural community with a high proportion of Aboriginal patients. J Pharm Policy Pract. It can also improve outcomes by minimizing the risk of hospital-acquired conditions. When compared to NLOS, events of PLOS showed a greater proportion of admissions from the ED (28.8% vs 11.0%, p<0.001), were more likely to be admitted on weekends (36.5 vs 30.9%, p<0.001), and were more likely to occur in shared rooms (78.1 vs 71.9%, p<0.001). We analyzed 85,904 hospitalizations (1,069,875 bed-days), of which 4,427 (5.1%) were PLOS (247,428 bed-days, 23.1% of total bed-days). Click through the PLOS taxonomy to find articles in your field. 2020 Apr 15;8:156. doi: 10.3389/fped.2020.00156. Main outcome measures: The National Hospital Discharge Survey (NHDS), 2005-2006, was evaluated for presence of dysphagia and the most common comorbid medical conditions. The number of comorbidities and lower socioeconomic status were also associated with an increased risk of PLOS, as previously reported[21]. In Germany, ≤50% of patients are malnourished at the time of hospital admission , , .Malnutrition has been identified as an independent risk factor for morbidity and mortality that is associated with a significantly longer hospital length of stay (LOS) for malnourished patients , , , thus the need for comprehensive screening programs has been acknowledged. On the other hand, our study derives information from a real-world medical records database that is systematically populated since 2000, so we have consistent information about our hospital discharges for a considerable period of time. PLOS were defined as those above the 95th percentile of length of hospitalization. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Background: This is similar to our results (23.1% of total hospital bed-days). Since hospitals are paid by the “DRG” (diagnosis related group), the hospital is going to get paid the same amount for a patient with say, pneumonia, if that patient spends 4 days in the hospital or spends 8 days in the hospital. Incidence of prolonged length of stay after orthotopic liver transplantation and its influence on outcomes. Conceptualization, We report some key sociodemographic and disease-specific differences in patients with PLOS which include a younger age, male gender, a lower physician-to-patient ratio, emergency and weekend admissions, surgery, the number of comorbidities, residence outside Mexico City and lower socioeconomic status. Peterson K, Helfand M, Humphrey L, Christensen V, Carson S. 2013 Feb. Importantly, we also observed important changes in the frequency of PLOS over time and the adjusted risk of PLOS, during the study period, which are more noticeable before and after 2007, when the trend in increased frequency of PLOS and adjusted risk of PLOS over time, reversed significantly. Copyright: © 2018 Marfil-Garza et al. Investigation, We analyzed 85,904 hospitalizations (1,069,875 bed-days), of which 4,427 (5.1%) were PLOS (247,428 bed-days, 23.1% of total bed-days). from the wards to the ICU and back to the wards). Early readmissions (≤30 days), a measure of the quality of healthcare, are commonly considered as a risk factor for PLOS[10]. We also include the calendar-year in our model, and show the adjusted odds ratios for PLOS per calendar-year in Fig 3, Panel B, where we can observe that the adjusted risk of PLOS increases sharply between 2003 and 2007 in comparison to 2000, and then decreased afterwards in such degree of magnitude that the adjusted odds ratio of PLOS is lower in any calendar-year after 2012 in comparison to 2000. Each patient move can add one or two nights to length of stay, and patients that are In Fig 1 we show the hospitalization events according to four types of hospitalization, most hospitalizations were elective admissions with no surgical interventions performed during the hospitalization (“elective, non-surgical”, 50.8%); followed by elective admissions with surgeries performed during the hospitalization event (“elective, surgical”, 37.3%), emergency admissions with no surgeries performed during the hospitalization (“emergency, non-surgical”, 7.4%); and only a small proportion of hospitalizations were classified as “emergency, surgical”, 4.5%)(Fig 1, Panel A). Yes 2020 Sep 22;9(9):3055. doi: 10.3390/jcm9093055. Smith JO, Shiffman ML, Behnke M, Stravitz RT, Luketic VA, Sanyal AJ, Heuman DM, Fisher RA, Cotterell AH, Maluf DG, Posner MP, Sterling RK. Although the latter term has not been standardized, overall, these patients have worse outcomes, both from the health and socioeconomic perspectives[3–5]. Hospitalizations events due to hematopoietic neoplasms (aOR 2.82, 95% CI 2.40–3.32), diseases of the peritoneum (aOR 2.82, 95% CI 2.33–3.41), complex intestinal and abdominal disorders (aOR 2.56, 95% CI 1.98–3.32), sepsis and severe bacterial infections (aOR 2.21, 95% CI 1.78–2.72), tuberculosis (aOR 2.05, 95% CI 1.52–2.78), peripheral nerve and muscle disorders (aOR 1.95, 95% CI 1.41–2.69), inflammatory bowel disease (aOR 1.74, 95%CI 1.25–2.15), among others also had an increased risk of PLOS (Fig 2). In addition, the unadjusted annual frequency of PLOS events and median LOS is summarized in Fig 3. PLoS ONE 13(11): Adjusted risk of a prolonged length of stay (PLOS) event by diagnosis at…, Fig 3. We used multivariate logistic regression analysis to identify factors associated with PLOS. e18936. Validation, In our study, in-hospital crude mortality in patients with PLOS nearly tripled as compared to patients with NLOS. Data are available upon request from the Department of Medicine of the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán and Ethics and Research Committee. A descriptive and comparative analysis of PLOS and NLOS patients was conducted. Moreover, despite the relevance of LOS in healthcare administration and healthcare epidemiology, there is a lack of knowledge about factors related to LOS in Mexico and Latin America. While we used multivariate regression models to adjust for the potential confounding effect of measured variables, and use IPW to correct for the potential selection bias and confounding associated to discharge diagnosis, we may still have significant effect of unmeasured confounders. https://doi.org/10.1371/journal.pone.0207203.t002, After adjusting for age, gender, physician-to-patient ratio, type of admission, readmission at 30 days, day of admission (weekday vs weekend), number of additional diagnosis, place of residence and socioeconomic status, we observed that hospitalization events associated to bone marrow transplant had the highest risk of PLOS (aOR = 18.4, 95% CI = 12.50–27.05); followed by systemic mycoses and parasitosis (aOR 4.6, 95% CI 3.9–6.4)(Fig 2). The median socioeconomic level was 3 [IQR 2–4]. Ofori-Asenso R, Liew D, Mårtensson J, Jones D. J Clin Med. Br J Anaesth.

Writing – review & editing, Affiliation VA Evidence Synthesis Program Evidence Briefs. The median LOS for all hospitalization events was 8 days in 2000, peaked at 10 days in 2006 and 2007 and then declined to 8 days afterwards and up to 2015, when it declined again by one day (B). Risk factors for intrahospital infection in newborns. Still, factors leading to this “weekend effect” are not completely understood[9]. Writing – original draft, We used Stata v12 software (StataCorp, 2012, College Station, Texas) for all statistical analyses. The International Classification of Diseases, in its 9th version was used for codification of surgeries and its 10th version for diagnoses. We compared the characteristics of hospitalization events by LOS (NLOS vs PLOS) in Table 1. Citation: Marfil-Garza BA, Belaunzarán-Zamudio PF, Gulias-Herrero A, Zuñiga AC, Caro-Vega Y, Kershenobich-Stalnikowitz D, et al. We analyzed our Institution´s hospital discharge database which contains information of all hospitalization events. We conducted a retrospective analysis of hospital discharges from January 2000-December 2017 using institutional databases of medical records. Investigation, An increased length of stay in the hospital not only increases the cost of health care but also adds to the risk of medical complications like infections and medical errors. Finally, it is generally accepted that the leading determinant for a patient’s LOS is the main diagnosis. For a five-night stay, this increased to a 5.5 per cent chance of a drug reaction, a 17.6 per cent chance of a hospital-acquired infection and a 3.1 per cent chance of an ulcer. Patient-level hospital costs and length of stay after conventional versus minimally invasive total hip replacement: a propensity-matched analysis. We then fit a multivariate logistic regression model to estimate the risk of PLOS including age, gender, physician-to-patient ratio, type of admission, rehospitalization at 30 days, day of admission (weekday vs weekend), number of additional diagnosis, place of residence and socioeconomic status, and used inverse probability weights (IPW) to adjust for the effect of the discharge diagnosis on LOS. Results: Risk of mortality in patients with PLOS increased more than threefold (3.7% vs 13.3%, p<0.001). Briefly, PLOS events occurred among younger people (48 years [IQR 32–62] vs 52 years [IQR 35–66], p<0.001); and had a lower median socioeconomic level (2 [IQR 2–3] vs 3 [IQR 2–4], p<0.001).  |  correction. We report some key sociodemographic and disease-specific differences in patients with PLOS. No, Is the Subject Area "Critical care and emergency medicine" applicable to this article? doi: 10.1371/journal.pone.0209944. Tefera GM, Feyisa BB, Umeta GT, Kebede TM. We observed that early readmission was associated with an increased risk of PLOS (aOR 1.05, 95% CI 1.018–1.088) when compared to late readmission (>30 days). Discover a faster, simpler path to publishing in a high-quality journal. Comparison between regions shows that the increased LOS due to HAI in South China is obviously longer than other regions except the Northeast. Hematological neoplasms were the most common discharge diagnosis and surgery of the small bowel was the most common type of surgery. A health care-acquired infection (HAI) is defined as an infection occurring during the process of care in a hospital or other health care facility, neither present nor incubating at the time of admission nor at the time of a visit to a health care facility. Hospitalized patients who develop a pressure ulcer during their hospital stay are at a greater risk for increased length of stay as compared with patients who do not. We abide to the Principles of the Declaration of Helsinki. First, to identify the risk of PLOS by group of diagnosis adjusting for potential confounders, we fit a multinomial logistic regression model for the 55 different diagnostic groups. Odds ratios for PLOS by diagnosis at discharge were adjusted for age, gender, physician-to-patient ratio, type of admission, readmission at 30 days, day of admission (weekday vs weekend), number of additional diagnosis, place of residence and socioeconomic status using multinomial logistic regression models fixing “Diseases of the liver, biliary tract and pancreas (K70.0-K79.9, K83.0-K89.9)” as the reference group. Hospitalizations in shared rooms have been reported to increase the risk of PLOS[15], but we did not observed this phenomenon in our population. We sought to describe and compare characteristics of patients with Normal hospital Length-of-Stay (NLOS) and PLOS to identify sociodemographic and disease-specific factors associated with PLOS in a tertiary care institution that attends adults with complicated diseases from all over Mexico. We used multinomial logistic regression models to control for age, gender, type of admission, recent hospital discharge, weekday/weekend admission, additional diagnoses, place of residence and socioeconomic status, using inverse probability weights based on diagnosis of admission. The frequency of PLOS was significantly higher during hospitalization events that required a surgical intervention. We defined PLOS events based on the 95th percentile LOS, which has been previously used [4]. 1 Malnutrition is associated with increased morbidity 2 and complications, and leads to increased length of hospital stay (LOS), therapeutic hospital and rehabilitation cost. We also observed several diagnosis groups to be associated with an increased risk for PLOS. Hospital length-of-Stay has been traditionally used as a surrogate to evaluate healthcare efficiency, as well as hospital resource utilization. Even though PLOS patients typically represent a small percentage of the total population of hospitalized patients in other studies (3.6–5.6%)[22], they account for approximately 20% of hospital bed-days[6].

For more information about PLOS Subject Areas, click Project administration, This contrasts with our results, and could be explained by a regional effect, as male patients in Mexico tend to seek less medical attention[18] which may translate in a more severe disease status at admission. Methodology, Methodology, 2001 Jul-Aug;32(4):304-11. doi: 10.1016/s0188-4409(01)00281-8. Missing data was handled as described above. For those that survive their stay in the ED and are transferred to the general hospital wards, a more comprehensive diagnostic approach and therapeutic management is often required. Introduction. (2018) 2018;13(4):e0195901 10.1371/journal.pone.0195901 ; PubMed Central PMCID: PMCPMC5898738. Yes Socioeconomic status is a construct used by the MNIH that comprises the following elements: monthly household income, family’s main provider’s occupation, monthly household expenses, housing conditions and family’s health status. These could serve to develop a specific model of directed hospital healthcare for patients identified as in risk of PLOS. On the other hand, to our knowledge this is the first study evaluating physician-to-patient ratio and its impact on LOS. (A) Overall Distribution of PLOS events by type of hospitalization (elective or emergency and surgical and non-surgical). Accesed on 07/19/2016. View Surgery was performed in 41.8% of hospitalization events. LOS is determined by a complex interweaving network of multiple supply and demand factors which operate at macro-, meso-, and micro-levels. Predictors of prolonged length of hospital stay and in-hospital mortality among adult patients admitted at the surgical ward of Jimma University medical center, Ethiopia: prospective observational study. COVID-19 is an emerging, rapidly evolving situation. We investigated the effect of a hospital-wide program for the prevention of HAIs on additional length of stay (LOS). Prolonged Length-of-stay (PLOS) is associated with increased mortality and other poor outcomes. El Camino Hospital, a 395-bed multi-specialty community hospital in Mountain View, Calif., places a high priority on keeping patients safe. A gout flare was reported in 42 of 326 admissions (13%) and the median length of stay for patients with a gout flare was longer than that of those without a flare (10 vs 6 days) or without gout (6 days). Background Hospital length-of-Stay has been traditionally used as a surrogate to evaluate healthcare efficiency, as well as hospital resource utilization. We hypothesize that changes in the infrastructure, organization and logistics in our hospital might account for these trends. The organization embraced the …  |  Categorical variables were compared using the chi-squared test. Is the Subject Area "Cancer risk factors" applicable to this article? We included age, gender, physician-to-patient ratio, type of admission, readmission at 30 days, day of admission (weekday vs weekend), number of additional diagnoses, place of residence and socioeconomic status. Other factors previously identified to be associated with PLOS are gender, hospitalizations in shared rooms, admissions through the ED, comorbidities and socioeconomic status. Liver Transpl. In 2014, 44% of Mexicans’ health expenditure was absorbed by patients themselves, compared to 11% in the U.S.A.[1]. Furthermore, we corroborated the phenomenon of increased risk of early readmission in the non-surgical population compared to the surgical population (32.1% vs 21.9%, p<0.001) that has already been reported in other studies [11, 12]. Objectives We developed an outcome indicator based on the finding that complications often prolong the patient's hospital stay. Investigation, The following variables were evaluated for all episodes of hospitalization: LOS in days, age at discharge in years, gender, type of admission (elective or emergency), type of hospitalization (as previously described[6]; “elective, non-surgical”, “elective, surgical”, “emergency, non-surgical”, and “emergency, surgical”), type of hospital bed (shared or private), physician-to-patient ratio (20 beds per medical team [January 2000-February 2008] or 12 beds per medical team [March 2008-December 2017]), day of admission (weekday [Monday-Thursday] or weekend [Friday-Sunday]), total number of events of hospitalization, number and type of readmission (early: ≤30 days from a previous hospitalization event or late: >30 days from a previous hospitalization event), days to readmission, surgery (only those procedures occurring in operating rooms), number of surgeries during hospitalization event, number of additional diagnoses (comorbidities), place of residence, diagnosis at discharge, socioeconomic status, in-hospital crude mortality and location of death (hospitalization ward, ED or ICU). These groups were organized and agreed by all authors considering frequency of the disease or surgery and specific clinical characteristics (e.g. The Frequency of, and Factors Associated with Prolonged Hospitalization: A Multicentre Study in Victoria, Australia. No, Is the Subject Area "Socioeconomic aspects of health" applicable to this article? Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City, Mexico, Roles Surgical hospitalizations showed an increased risk for PLOS, both when elective (aOR 2.92, 95% CI 2.85–2.99) or emergency (aOR 5.07, 95% CI 4.84–5.30) admissions were considered. eCollection 2020. Finally, having a low socioeconomic status also increased the risk of PLOS (Table 3). Information regarding physician-to-patient ratios and outcomes is scarce, but there is some evidence suggesting that increasing physician supply might reduce mortality and ED admissions [8]. Competing interests: The authors have declared that no competing interests exist. The relationship between length of in-hospital stay (LOS) and quality of care is difficult. Health Care Manag Sci. Additionally, these patients represent a significant economic problem on public health systems and their families. Finally, given that a significant proportion of patients (especially patients with PLOS) are not able to pay for their whole hospital stay, this also impacts the budget of the institution (in 2015, patients with PLOS at our Institution only covered 15.7% of their total hospitalization expenses; unpublished data).
