Abstract
BACKGROUND Hospitals reduce staffing levels and services on weekends. This raises the question of whether weekend discharges may be inadequately prepared and thus at higher risk for adverse events postdischarge. OBJECTIVE To compare death or nonelective readmission rates 30 days after weekend versus weekday discharge. DESIGN Retrospective cohort. SETTING All teaching hospitals in Alberta, Canada. PATIENTS General internal medicine (GIM) discharges (only 1 per patient). MEASUREMENTS Analyses were adjusted for demographics, comorbidity, and length of stay based on a previously validated index. RESULTS Of 7991 patients (mean age, 62.1 years; 51.9% male; mean Charlson 2.56; 57.5% LACE ≥10) discharged from 7 teaching hospitals, 1146 (14.3%) were discharged on a weekend. Although they had substantially shorter lengths of stay (5.64 days, 95% confidence interval [CI]: 5.35-5.93 vs 7.86 days, 95% CI: 7.71-8.00, adjusted P value < 0.0001) and were less likely to be discharged with homecare support (10.9% vs 19.3%) or to long-term care facilities (3.1% vs 7.8%), patients discharged on weekends exhibited similar rates of death or readmission at 30 days compared to those discharged on weekdays (10.6% vs 13.2%, adjusted odds ratio [aOR]: 0.94, 95% CI: 0.77-1.16), even among the 4591 patients deemed to be at high risk for postdischarge events based on LACE (length of hospital stay, acuity of admission, comorbidity burden quantified using the Charlson Comorbidity Index, and emergency department visits in the 6 months prior to admission) score ≥10 (16.8% vs 16.5% for weekday discharges, aOR: 1.09 [95% CI: 0.85-1.41]). CONCLUSIONS GIM patients discharged from teaching hospitals on weekends have shorter lengths of stay and exhibit similar postdischarge outcomes as patients discharged on weekdays.

Abstract
OBJECTIVE The purpose of this study was to evaluate the association of physician continuity of care with length of stay, likelihood of weekend discharge, in-hospital mortality and 30-day readmission. DESIGN A cohort study of hospitalized medical patients. The primary exposure was the weekend usual provider continuity (UPC) over the initial weekend of care. This metric was adapted from an outpatient continuity of care index. Regression models were developed to determine the association between UPC and outcomes. SETTING An academic medical center. MAIN OUTCOME MEASURE Length of stay which was calculated as the number of days from the first Saturday of the hospitalization to the day of discharge. RESULTS Of the 3391 patients included in this study, the prevalence of low, moderate and high UPC for the initial weekend of hospitalization was 58.7, 22.3 and 19.1%, respectively. When compared with low continuity of care, both moderate and high continuity of care were associated with reduced length of stay, with adjusted rate ratios of 0.92 (95% CI 0.86-1.00) and 0.64 (95% CI 0.53-0.76), respectively. High continuity of care was associated with likelihood of weekend discharge (adjusted odds ratio 2.84, 95% CI 2.11-3.83) but was not significantly associated with mortality (adjusted odds ratio 0.72, 95% CI 0.29-1.80) or readmission (adjusted odds ratio 0.88, 95% CI 0.68-1.14) when compared with low continuity of care. CONCLUSIONS Increased weekend continuity of care is associated with reduced length of stay. Improvement in weekend cross-coverage and patient handoffs may be useful to improve clinical outcomes.

Outcome of holiday and nonholiday admission patients with acute peptic ulcer bleeding: a real-world report from southern Taiwan. BIOMED RESEARCH INTERNATIONAL 2014; 2014:906531. [PMID: 25093189 PMCID: PMC4100444 DOI: 10.1155/2014/906531] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2014] [Accepted: 06/18/2014] [Indexed: 01/18/2023]
Abstract
Background. Recent findings suggest that patients admitted on the weekend with peptic ulcer bleeding might be at increased risk of adverse outcomes. However, other reports found that there was no “holiday effect.” The purpose of this study was to determine if these findings hold true for a real-life Taiwanese medical gastroenterology practice. Materials and Methods. We reviewed the medical files of hospital admissions for patients with peptic ulcer bleeding who received initial endoscopic hemostasis between January 2009 and March 2011. A total of 744 patients were enrolled (nonholiday group, n = 615; holiday group, n = 129) after applying strict exclusion criteria. Holidays were defined as weekends and national holidays in Taiwan. Results. Our results showed that there was no significant difference in baseline characteristics between the two groups. We also observed that, compared to the nonholiday group, patients in the holiday group received earlier endoscopy treatment (12.20 hours versus 16.68 hours, P = 0.005), needed less transfused blood (4.8 units versus 6.6 units, P = 0.02), shifted from intravenous to oral proton-pump inhibitors (PPIs) more quickly (5.3 days versus 6.9 days, P = 0.05), and had shorter hospital stays (13.05 days versus 17.36 days, P = 0.005). In the holiday and nonholiday groups, the rebleeding rates were 17.8% and 23.41% (P = 0.167), the mortality rates were 11.63% versus 13.66% (P = 0.537), and surgery was required in 2.11% versus 4.66% (P = 0.093), respectively. Conclusions. Patients who presented with peptic ulcer bleeding on holidays did not experience delayed endoscopy or increased adverse outcomes. In fact, patients who received endoscopic hemostasis on the holiday had shorter waiting times, needed less transfused blood, switched to oral PPIs quicker, and experienced shorter hospital stays.

Abstract
AIM: To evaluate the “weekend effect” on outcomes in patient admitted on the weekend for upper gastrointestinal bleeding (UGIB).
METHODS: A comprehensive search was performed (March 2014). Studies comparing weekend and weekday endoscopy in patients with UGIB were included. All studies had at least 2 of 3 primary outcomes which included: mortality, need for surgery, time to endoscopy, endoscopy on admission day, and length of hospital stay. Three authors individually extracted data. Meta-analysis was performed using pooled estimates with odds ratio or mean difference by fixed and random effects models.
RESULTS: Eleven studies met the inclusion criteria. Patients admitted with UGIB on the weekend exhibited a statistically significant increase in mortality (OR = 1.13; 95%CI: 1.06-1.20; P < 0.01), need for surgery (OR = 2.46; 95%CI: 1.51-3.99; P < 0.01), and time to endoscopy (MD 2.68; 95%CI: 0.17-5.20; P = 0.04) as compared to patients admitted with UGIB on a weekday. Furthermore, patients with UGIB admitted on weekend experienced statistically significant less endoscopy on day of admission (OR = 0.72; 95%CI: 0.62-0.85; P < 0.01). No difference was noted between the two groups for length of hospital stay (MD -1.29; 95%CI: -3.03-0.45; P = 0.15).
CONCLUSION: A weekend effect seems to be apparent in patients with UGIB with significantly poorer outcomes.

BMC Health Serv Res 2014; 14:226. [PMID: 24886152 PMCID: PMC4053268 DOI: 10.1186/1472-6963-14-226] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2013] [Accepted: 04/25/2014] [Indexed: 11/26/2022] Open
Abstract
Background Current prognostic models factor in patient and disease specific variables but do not consider cumulative risks of hospitalization over time. We developed risk models of the likelihood of death associated with cumulative exposure to hospitalization, based on time-varying risks of hospitalization over any given day, as well as day of the week. Model performance was evaluated alone, and in combination with simple disease-specific models. Method Patients admitted between 2000 and 2006 from 501 public and private hospitals in NSW, Australia were used for training and 2007 data for evaluation. The impact of hospital care delivered over different days of the week and or times of the day was modeled by separating hospitalization risk into 21 separate time periods (morning, day, night across the days of the week). Three models were developed to predict death up to 7-days post-discharge: 1/a simple background risk model using age, gender; 2/a time-varying risk model for exposure to hospitalization (admission time, days in hospital); 3/disease specific models (Charlson co-morbidity index, DRG). Combining these three generated a full model. Models were evaluated by accuracy, AUC, Akaike and Bayesian information criteria. Results There was a clear diurnal rhythm to hospital mortality in the data set, peaking in the evening, as well as the well-known ‘weekend-effect’ where mortality peaks with weekend admissions. Individual models had modest performance on the test data set (AUC 0.71, 0.79 and 0.79 respectively). The combined model which included time-varying risk however yielded an average AUC of 0.92. This model performed best for stays up to 7-days (93% of admissions), peaking at days 3 to 5 (AUC 0.94). Conclusions Risks of hospitalization vary not just with the day of the week but also time of the day, and can be used to make predictions about the cumulative risk of death associated with an individual’s hospitalization. Combining disease specific models with such time varying- estimates appears to result in robust predictive performance. Such risk exposure models should find utility both in enhancing standard prognostic models as well as estimating the risk of continuation of hospitalization.

Abstract
OBJECTIVE Previous studies have suggested that weekend hospital care is inferior to weekday care and that this difference may be related to diminished care intensity. The purpose of this study was to determine whether a metric for measuring intensity of hospital care based on use of the electronic health record was associated with patient-level outcomes. METHODS We performed a cohort study of hospitalizations at an academic medical center. Intensity of care was defined as the hourly number of provider accessions of the electronic health record, termed "electronic health record interactions." Hospitalizations were categorized on the basis of the mean difference in electronic health record interactions between the first Friday and the first Saturday of hospitalization. We used regression models to determine the association of these categories with patient outcomes after adjusting for covariates. RESULTS Electronic health record interactions decreased from Friday to Saturday in 77% of the 9051 hospitalizations included in the study. Compared with hospitalizations with no change in Friday to Saturday electronic health record interactions, the relative lengths of stay for hospitalizations with a small, moderate, and large decrease in electronic health record interactions were 1.05 (95% confidence interval [CI], 1.00-1.10), 1.11 (95% CI, 1.05-1.17), and 1.25 (95% CI, 1.15-1.35), respectively. Although a large decrease in electronic health record interactions was associated with in-hospital mortality, these findings were not significant after risk adjustment (odds ratio 1.74, 95% CI, 0.93-3.25). CONCLUSIONS Intensity of inpatient care, measured by electronic health record interactions, significantly diminished from Friday to Saturday, and this decrease was associated with length of stay. Hospitals should consider monitoring and correcting temporal fluctuations in care intensity.

Abstract
OBJECTIVE To assess the association between off-hour (weekends and nights) presentation, door to balloon times, and mortality in patients with acute myocardial infarction. DATA SOURCES Medline in-process and other non-indexed citations, Medline, Embase, Cochrane Database of Systematic Reviews, and Scopus through April 2013. STUDY SELECTION Any study that evaluated the association between time of presentation to a healthcare facility and mortality or door to balloon times among patients with acute myocardial infarction was included. DATA EXTRACTION Studies' characteristics and outcomes data were extracted. Quality of studies was assessed with the Newcastle-Ottawa scale. A random effect meta-analysis model was applied. Heterogeneity was assessed using the Q statistic and I(2). RESULTS 48 studies with fair quality, enrolling 1,896,859 patients, were included in the meta-analysis. 36 studies reported mortality outcomes for 1,892,424 patients with acute myocardial infarction, and 30 studies reported door to balloon times for 70,534 patients with ST elevation myocardial infarction (STEMI). Off-hour presentation for patients with acute myocardial infarction was associated with higher short term mortality (odds ratio 1.06, 95% confidence interval 1.04 to 1.09). Patients with STEMI presenting during off-hours were less likely to receive percutaneous coronary intervention within 90 minutes (odds ratio 0.40, 0.35 to 0.45) and had longer door to balloon time by 14.8 (95% confidence interval 10.7 to 19.0) minutes. A diagnosis of STEMI and countries outside North America were associated with larger increase in mortality during off-hours. Differences in mortality between off-hours and regular hours have increased in recent years. Analyses were associated with statistical heterogeneity. CONCLUSION This systematic review suggests that patients with acute myocardial infarction presenting during off-hours have higher mortality, and patients with STEMI have longer door to balloon times. Clinical performance measures may need to account for differences arising from time of presentation to a healthcare facility.

Abstract
In hospitals, nurses provide patient care around the clock, but the impact of night staff characteristics on patient outcomes is not well understood. The aim of this study was to examine the association between night nurse staffing and workforce characteristics and the length of stay (LOS) in 138 veterans affairs (VA) hospitals using panel data from 2002 through 2006. Staffing in hours per patient day was higher during the day than at night. The day nurse workforce had more educational preparation than the night workforce. Nurses' years of experience at the unit, facility, and VA level were greater at night. In multivariable analyses controlling for confounding variables, higher night staffing and a higher skill mix were associated with reduced LOS.

Abstract
Variations in outcome relating to out-of-hours care have received considerable attention. We conducted a retrospective cohort study to determine the effect of day and time of admission on mortality in an intensive care unit (ICU) with representative admission severity of illness. Data pertaining to 4,183 patients admitted between 2000 and 2007 were extracted from a prospectively maintained database. Case-mix adjustment was undertaken using the UK APACHE II probability of hospital death. The mean APACHE score was 20.9 with a median predicted hospital mortality of 32.5%. Actual hospital mortality was 30.8%. Compared with Wednesdays as the reference day, admission to ICU on any other given day was not associated with higher crude or case-mix adjusted mortality. Admission to ICU in the evening, compared with daytime admission, was associated with lower odds of crude hospital mortality, but this difference was no longer significant after case-mix adjustment. Case-mix adjusted in-hospital mortality does not vary with day and time of admission, even in patients with higher severity of illness and higher predicted mortality than previously reported.

Abstract
BACKGROUND Hospital care on weekends has been associated with reduced quality and poor clinical outcomes, suggesting that decreases in overall intensity of care may have important clinical effects. We describe a new measure of hospital intensity of care based on utilization of the electronic health record (EHR). METHODS We measured global intensity of care at our academic medical center by monitoring the use of the EHR in 2011. Our primary measure, termed EHR interactions, was the number of accessions of a patient's electronic record by a clinician, adjusted for hospital census, per unit of time. Our secondary measure was percent of total available central processing unit (CPU) power used to access EHR servers at a given time. RESULTS EHR interactions were lower on weekend days as compared to weekdays at every hour (P < 0.0001), and the daytime peak in intensity noted each weekday was blunted on weekends. The relative rate and 95% confidence interval (CI) of census-adjusted record accessions per patient on weekdays compared with weekends were: 1.76 (95% CI: 1.74-1.77), 1.52 (95% CI: 1.50-1.55), and 1.14 (95% CI: 1.12-1.17) for day, morning/evening, and night hours, respectively. Percent CPU usage correlated closely with EHR interactions (r = 0.90). CONCLUSIONS EHR usage is a valid and easily reproducible measure of intensity of care in the hospital. Using this measure we identified large, hour-specific differences between weekend and weekday intensity. EHR interactions may serve as a useful measure for tracking and improving temporal variations in care that are common, and potentially deleterious, in hospital systems.

Abstract
BACKGROUND Previous studies have demonstrated a relationship between longer interdialytic intervals and hospitalization for cardiovascular causes in adults maintained on hemodialysis (HD). This association has not been previously demonstrated in children. We hypothesized that the risk of hospitalization for hypertension (HTN), fluid overload or electrolyte abnormalities would be increased on the days following a longer interdialytic interval in children. METHODS We queried the Pediatric Hospital Information System for all admissions of patients with chronic kidney disease stage V or V-D who received dialysis during the hospitalization. Admissions were divided into two categories: admissions for HTN, fluid overload or electrolyte abnormalities and admissions for all other causes. We assumed that HD patients did not receive dialysis on weekends, and therefore any admission on Monday occurred following a longer interval from the last dialysis. We assumed that all peritoneal dialysis (PD) patients received dialysis on a daily basis. We used mixed effects logistic regression, clustering by patient within each hospital, to assess the increased odds for cause-specific admission on Monday versus other days of the week. We stratified the analysis by dialysis modality, HD or PD. RESULTS Among HD patients, the odds ratio of admission for HTN, fluid overload or electrolyte abnormalities was 2.6 (95% CI = 1.4-4.7, P = 0.003) if the admission occurred on a Monday versus other days of the week. The odds of cause-specific admission among PD patients was not significantly different on Monday compared with other days of the week (95% CI =0.5-1.3, P = 0.8). CONCLUSION Children receiving chronic HD are more likely to be hospitalized for HTN, fluid overload or electrolyte abnormalities following a longer interdialytic interval. Changes to the frequency of outpatient dialysis treatments may decrease admissions in this population and decrease resource utilization in this high-risk population.

Abstract
BACKGROUND It is unclear whether teaching status or day of discharge influences outcomes after a heart failure hospitalization. METHODS AND RESULTS We evaluated adults discharged after a heart failure hospitalization between 1999 and 2009 in Alberta, Canada. The primary outcome was death or nonelective readmission 30 days postdischarge. Of 12 216 patients discharged from teaching hospitals and 12 157 patients from nonteaching hospitals, 20 524 (84%) discharges occurred on weekdays. Although they had greater comorbidity and used more healthcare resources before their heart failure hospitalization, patients discharged from teaching hospitals exhibited shorter lengths of stay (adjusted ratio, 0.83; 95% confidence interval [CI], 0.80-0.86) and significantly lower rates of death or readmission in the 30 days after discharge than those discharged from nonteaching hospitals (17.4% versus 22.1%; adjusted hazard ratio [aHR], 0.83; 95% CI, 0.77-0.89). Patients discharged on weekdays were older and had greater comorbidity, yet exhibited significantly lower rates of death or readmission at 30 days than those discharged on weekends (19.5% versus 21.1%; aHR, 0.87; 95% CI, 0.80-0.94). Compared with weekend discharge from a nonteaching hospital, 30-day death/readmission rates were lower for weekday discharge from a nonteaching hospital (aHR, 0.85; 95% CI, 0.77-0.94), weekend discharge from a teaching hospital (aHR, 0.80; 95% CI, 0.69-0.92), and weekday discharge from a teaching hospital (aHR, 0.71, 95% CI, 0.63-0.79). CONCLUSIONS Patients discharged from teaching hospitals or on weekdays exhibited better outcomes despite having higher risk profiles. Future studies should focus on distinguishing which discharge processes differ between teaching and nonteaching hospitals and between weekdays and weekends to define those that optimize patient outcomes.

Abstract
Numerous studies have documented a positive association between weekend hospitalization and mortality. Some researchers have argued that these associations are causal and arise from weekend reductions in hospital staffing. Others have suggested that the observed correlations reflect differences in the unobservable characteristics of weekend versus weekday patients. The existing literature has provided only limited evidence of the specific pathways through which weekend hospitalization might affect health outcomes. This article outlines the limitations of the existing research and highlights the need for in-depth condition-specific studies that acknowledge the potential threat posed by selection bias.

Abstract
We used prospective cohort data of patients with acute coronary syndrome (ACS) to compare their management on weekdays/mornings with weekends/nights, and the possible impact of this on 1-month and 1-year mortality. Analyses were evaluated using univariate and multivariate statistics. Of the 4,616 patients admitted to hospitals with ACS, 76% were on weekdays. There were no significant differences in 1-month (odds ratio (OR), 0.88; 95% CI: 0.68-1.14) and 1-year mortality (OR, 0.88; 95% CI: 0.70-1.10), respectively, between weekday and weekend admissions. Similarly, there were no significant differences in 1-month (OR, 0.92; 95% CI: 0.73-1.15) and 1-year mortality (OR, 0.98; 95% CI: 0.80-1.20), respectively, between nights and day admissions. In conclusion, apart from lower utilization of angiography (P < .001) at weekends, there were largely no significant discrepancies in the management and care of patients admitted with ACS on weekdays and during morning hours compared with patients admitted on weekends and night hours, and the overall 30-day and 1-year mortality was similar between both the cohorts.

Abstract
OBJECTIVE To assess the impact of the day of birth on twin mortality in a population sample. METHODS We analyzed weekend versus weekday twin births from the United States national twin birth data for the periods 1989-2002. We computed adjusted hazard ratios (HR) and 95% confidence intervals (CI) to assess the association between infant mortality and weekday of birth using the Cox proportional hazards model. RESULTS The crude rates for all types of mortality were found to be significantly higher for twins born on weekends than on weekdays. After adjustment, only post-neonatal mortality risk was higher on weekends as compared to weekdays [Hazards ratio (HR)=1.19, CI: 1.04, 1.36]. Twins of white mothers were at greater risk for neonatal death (HR=1.16, CI: 1.08, 1.24) but were less likely to experience post-neonatal death (HR=0.68, CI: 0.64, 0.76) as compared to twins of black mothers. We found an interaction between maternal age and weekday of birth. Twins born on weekends to teenage mothers (age<18) had a 35% greater risk for neonatal death (HR=1.35, CI: 1.06, 1.71) while those born on weekends to older mothers did not show elevated risk for any of the mortality indices. CONCLUSION Increased risks for post-neonatal death are significantly higher amongst twins born on weekends as compared to weekdays. Further research is required to identify the detailed differences in structure and procedures that result in the disadvantage associated with weekend birth.

Weekend admission to hospital has a higher risk of death in the elective setting than in the emergency setting: a retrospective database study of national health service hospitals in England. BMC Health Serv Res 2012; 12:87.

Abstract
Background Although acute hospitals offer a twenty-four hour seven day a week service levels of staffing are lower over the weekends and some health care processes may be less readily available over the weekend. Whilst it is thought that emergency admission to hospital on the weekend is associated with an increased risk of death, the extent to which this applies to elective admissions is less well known. We investigated the risk of death in elective and elective patients admitted over the weekend versus the weekdays. Methods Retrospective statistical analysis of routinely collected acute hospital admissions in England, involving all patient discharges from all acute hospitals in England over a year (April 2008-March 2009), using a logistic regression model which adjusted for a range of patient case-mix variables, seasonality and admission over a weekend separately for elective and emergency (but excluding zero day stay emergency admissions discharged alive) admissions. Results Of the 1,535,267 elective admissions, 91.7% (1,407,705) were admitted on the weekday and 8.3% (127,562) were admitted on the weekend. The mortality following weekday admission was 0.52% (7,276/1,407,705) compared with 0.77% (986/127,562) following weekend admission. Of the 3,105,249 emergency admissions, 76.3% (2,369,316) were admitted on the weekday and 23.7% (735,933) were admitted on the weekend. The mortality following emergency weekday admission was 6.53% (154,761/2,369,316) compared to 7.06% (51,922/735,933) following weekend admission. After case-mix adjustment, weekend admissions were associated with an increased risk of death, especially in the elective setting (elective Odds Ratio: 1.32, 95% Confidence Interval 1.23 to 1.41); vs emergency Odds Ratio: 1.09, 95% Confidence Interval 1.05 to 1.13). Conclusions Weekend admission appears to be an independent risk factor for dying in hospital and this risk is more pronounced in the elective setting. Given the planned nature of elective admissions, as opposed to the unplanned nature of emergency admissions, it would seem less likely that this increased risk in the elective setting is attributable to unobserved patient risk factors. Further work to understand the relationship between weekend processes of care and mortality, especially in the elective setting, is required.

Abstract
BACKGROUND The experience in performing intubation procedures gained by a single operator has been previously reported for adult, but not for neonatal patients. AIM In order to evaluate the process of skill acquisition, we reviewed the first 150 neonatal tracheal intubations performed by a pediatric trainee. METHODS For logbook purposes, a pediatric trainee prospectively recorded all neonatal tracheal intubation procedures that she performed during a 5-year training period. RESULTS During the study period, Nicoletta Doglioni performed for 152 intubation procedures. Of the 152 procedures, the author was successful on 120 (79%) occasions. Of these, 77 (64%) were performed on the first attempt, and 43 (36%) on the second attempt. Author successful intubation improved by the training year 1 (67%) to training year 2 (79%), 3 (77%), 4 (80%) and 5 (91%), respectively. CONCLUSIONS Intubation success rate progressively improved with training year experience. A recommended level of proficiency, defined as 90% of procedure success, was obtained after 100 attempts suggesting that a significant amount of experience is needed for obtaining proficiency in neonatal intubation.

Abstract
OBJECTIVE To quantify the difference in weekday versus weekend occupancy, and the opportunity to smooth inpatient occupancy to reduce crowding at children's hospitals. METHODS Daily inpatient census data for 39 freestanding, tertiary-care children's hospitals were used to calculate occupancy and to model the impact of reducing variation in occupancy and the change in the number of patients, patient-days, and hospitals exposed to high occupancy pre- and post-smoothing. We also calculated the proportion of weekly admissions that would require different scheduling to achieve within-week smoothing. RESULTS Overall, hospitals' mean occupancy ranged from 70.9% to 108.1% on weekdays, and 65.7% to 94.9% on weekends. Weekday occupancy exceeded weekend occupancy with a median difference of 8.2% points. The mean post-smoothing reduction in weekly maximum occupancy across all hospitals was 6.6% points. Through smoothing, 39,607 patients from the 39 hospitals were removed from exposure to occupancy levels >95%. To achieve within-week smoothing, a median 2.6% of admissions would have to be scheduled on a different day of the week; this equates to a median of 7.4 patients per week (range: 2.3-14.4). CONCLUSION Hospitals do have substantial unused capacity, and smoothing occupancy over the course of a week could be a useful strategy that hospitals can use to reduce crowding and protect patients from crowded conditions.

Abstract
OBJECTIVES An increased mortality in patients presenting to hospital at weekends has been observed for several medical conditions. The aim of this study is to examine the relationship between weekend presentation to hospital following acute upper gastrointestinal bleeding and mortality. METHODS Data were collected on 6,749 patients presenting to 212 UK hospitals. A logistic regression model was used to examine the relationship between weekend presentation to hospital and mortality. RESULTS Patients presenting at the weekend were more likely to present with shock (39% vs. 36%), hematemesis (41% vs. 38%), and receive red cell transfusion (42% vs. 39%). Only 38% of those presenting at weekends underwent endoscopy within 24 h compared with 55% admitted on weekdays (adjusted odds ratio (OR)=0.47, 95% confidence interval (CI)=0.41-0.54), although the proportion of all patients receiving endoscopic therapy was identical at weekends compared with weekdays (24%). After adjustment for confounders, there was no evidence of a difference between weekend and weekday mortality (OR=0.93; 95% CI=0.75-1.16). Similar results were seen when restricting the analysis to those patients who underwent endoscopy (n=5,004) (OR=0.87, 95% CI=0.65-1.16). There was no difference in the OR for mortality for weekend compared with weekday presentation between patients presenting to hospitals with an out-of-hours (OOH) endoscopy rota compared with those presenting to hospitals without such a facility. CONCLUSIONS In this large prospective study of acute upper gastrointestinal bleeding in the United Kingdom, there was no increase in mortality for weekend vs. weekday presentation despite patients being more critically ill and having greater delays to endoscopy at weekends. Provision of an OOH endoscopy service at weekends in the remaining UK hospitals may not lead to further reductions in case fatality, although a reduction in OOH endoscopy provision from current levels could lead to an increase in mortality at weekends.

Abstract
OBJECTIVES Adverse event or complication rates are increasingly advocated as measures of hospital quality and performance. Objective of this study is to analyse patient-complexity adjusted adverse events rates to compare the performance of hospitals in Victoria, Australia. We use a unique hospital dataset that routinely records adverse events which arise during the admission. We identify hospitals with below or above average performance in comparison to their peers, and show for which types of hospitals risk adjusting makes biggest difference. METHODS We estimate adverse event rates for 87,790 elective and 43,771 emergency episodes in 34 public hospitals over the financial year 2005/06 with a complementary log-log model, using patient level administrative hospital data and controlling for patient complexity with a range of covariates. RESULTS Teaching hospitals have average risk-adjusted adverse event rates of 24.3% for elective and 19.7% for emergency surgical patients. Suburban and rural hospitals have lower rates of 17.4% and 17%, and 16.1% and 15.7%, respectively. Selected non-teaching hospitals have relatively high rates, in particular hospitals in rural and socially disadvantaged areas. Risk adjustment makes a significant difference to most hospitals. CONCLUSION We find comparably high adverse events rates for surgical patients in Australian hospitals, possibly because our data allow identification of a larger number of adverse events than data used in previous studies. There are marked variations in adverse event rates across hospitals in Victoria, even after risk adjusting. We discuss how policy makers could improve quality of care in Australian hospitals.

Abstract
The off-peak work environment is important to understand because the risk for mortality increases for patients at night and on the weekend in hospitals. Because critical-care nurses are on duty in hospitals 24 hours a day, 7 days a week, they are excellent sources of information regarding what happens on a unit during off-peak times. Inadequate nurse staffing on off-peak shifts was described as a major problem by the nurses we interviewed. The study reported here contributes the type of information needed to better understand the organization of nursing units and nurse staffing on outcomes.

Abstract
BACKGROUND High hospital occupancy is a challenge for quality of care and access, while low levels of occupancy may be inefficient in terms of resource utilization. Variability from scheduling decisions may affect occupancy and be amenable to alteration. OBJECTIVE Describe variability in admission, discharge, and occupancy patterns at a large children's hospital and assess the relationship between scheduled admissions and occupancy. DESIGN Retrospective administrative data analysis. SETTING One urban, tertiary-care children's hospital. PATIENTS A total of 22,310 consecutive patients admitted from July 1, 2007 to June 30, 2008. MEASUREMENTS Admission-discharge-transfer (ADT) data for 1 fiscal year were abstracted for analysis of admission and occupancy patterns. RESULTS Among 22,310 admissions, 78% were coded as emergent and 22% as scheduled. Variation in admission volume by day of week was high for scheduled admissions (coefficient of variation [CV] 65.3%), while it was more consistent for emergent admissions (CV 12.0%). For patients with length of stay (LOS) ≤ 7 days (84%), Mondays and Tuesdays generated 45.2% of scheduled patient hours. Wednesdays and Thursdays had the highest frequency of high occupancy. CONCLUSIONS Scheduled admissions contribute significantly to variability in occupancy and risk of mid-week crowding. Predictable patterns of admissions lead to high occupancy on some days and unused capacity on others, which can be addressed with proactive management of admissions (eg, greater use of unused capacity on weekends and in summer). Hospitals interested in optimizing patient flow should assess their admission and occupancy patterns. Further studies should link variation in occupancy to outcomes including quality of care, educational activities, and staff satisfaction.

Abstract
OBJECTIVE To determine whether outcomes for patients admitted with UGIH differ depending on weekend versus weekday admission, and whether any such differences are mediated by discrepancies in the use and timing of endoscopy. METHODS This was a cross-sectional comparison of mortality, resource use, and the utilization and timing of esophagogastroduodenoscopy (EGD) among patients admitted with upper gastrointestinal hemorrhage (UGIH) on weekends to those admitted on a weekday. Hospitals in 31 states from the Nationwide Inpatient Sample between 1998 and 2003 were included. This resulted in 75,636 patients admitted during the week and 23,339 admitted on a weekend with UGIH. Multivariable analyses were conducted to evaluate the effect of weekend admission on UGIH outcomes. RESULTS Compared to patients admitted on a weekday, for those admitted on a weekend: in-hospital mortality was higher (unadjusted mortality 3.76 vs. 3.33%; P = 0.003; adjusted HR = 1.09, 95% CI = 1.00-1.18); adjusted length of stay was 1.7% longer (P = 0.0098); and adjusted in-hospital charges were 3.3% higher (P = 0.0038). Although these patients were less likely to undergo endoscopy (adjusted OR = 0.94; P = 0.004) and waited longer for this procedure (adjusted HR = 0.87; P < 0.001), these discrepancies did not fully explain their inferior outcomes. CONCLUSIONS Weekend admission for UGIH is associated with an increased risk of death, slightly longer lengths of stay, and marginally higher in-patient charges. Discrepancies in the use and timing of endoscopy do not account for these differences.

Abstract
Background—
We sought to describe the long-term prognosis after routine primary percutaneous coronary intervention (pPCI) in a contemporary consecutive population of patients with presumed ST-segment elevation myocardial infarction, compare it with similar results from the landmark DANAMI-2 trial, and to identify a possible impact of time of presentation and referral pattern.
Methods and Results—
Long-term prognosis in 1019 presumed ST-segment elevation myocardial infarction patients, treated according to modern routine pPCI during the year 2004, was analyzed and compared with similar data from the DANAMI-2 trial. Furthermore, we analyzed the impact of patient presentation to the angioplasty center during “off hours” (4
pm
to 8
am
plus weekends and holidays) and the impact of being referred from noninvasive hospitals. At 3 years, 20.4% in the routinely treated population versus 19.6% in the DANAMI-2 trial reached the combined end point of death, reinfarction, or stroke (
P
=0.68), whereas the all-cause mortality was 13.0% and 13.7%, respectively (
P
=0.65). Patients admitted during off hours had the same risk of reaching the combined end point of death, reinfarction, or stroke compared with patients admitted during office hours (hazards ratio, 1.04; 95% CI, 0.8 to 1.5;
P
=0.81). Door-to-balloon times of less than 90 minutes were achieved in 60% among patients admitted directly to an invasive center but only in 40% among transferred patients (
P
<0.001). Despite this difference, no difference in unadjusted or adjusted long-term prognosis was found between the 2 groups.
Conclusions—
This study shows that ST-segment elevation myocardial infarction patients treated with contemporary routine pPCI achieve a similar long-term prognosis as patients in the landmark randomized pPCI trial (DANAMI-2). Furthermore, the long-term prognosis was the same regardless of whether the pPCI was performed during off hours or office hours. Thus, pPCI including transportation of patients from noninvasive centers can be applied successfully in a real-life population.

The effect of weekend versus weekday admission on outcomes of esophageal variceal hemorrhage. CANADIAN JOURNAL OF GASTROENTEROLOGY = JOURNAL CANADIEN DE GASTROENTEROLOGIE 2009; 23:495-501. [PMID: 19623333 DOI: 10.1155/2009/713789] [Citation(s) in RCA: 44] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/21/2023]
Abstract
BACKGROUND Hospital staffing is often lower on weekends than weekdays, and may contribute to higher mortality in patients admitted on weekends. Because esophageal variceal hemorrhage (EVH) requires complex management and urgent endoscopic intervention, limitations in physician expertise and the availability of endoscopy on weekends may be associated with increased EVH mortality. OBJECTIVE To assess the differences in mortality, hospital length of stay (LOS), and costs between patients admitted on weekends versus patients who were admitted on weekdays. METHODS The United States Nationwide Inpatient Sample database was used to identify patients hospitalized for EVH between 1998 and 2005. Differences in mortality, LOS, and costs between patients admitted on weekends and weekdays were evaluated using regression models with adjustment for patient and clinical factors, including the timing of endoscopy. RESULTS Between 1998 and 2005, 36,734 EVH admissions to 2207 hospitals met the inclusion criteria. Compared with patients admitted on weekdays, individuals admitted on the weekend were slightly less likely to undergo endoscopy on the day of admission (45% versus 43%, respectively; P=0.01) and by the second day (81% versus 75%; P<0.0001). However, mortality (11.3% versus 10.8%; P=0.20) and the requirement for endoscopic therapy (70% versus 69%; P=0.08) or portosystemic shunt insertion (4.4% versus 4.7%; P=0.32) did not differ between weekend and weekday admissions. After adjusting for confounding factors, including the timing of endoscopy, the risk of mortality was similar between weekend and weekday admissions (OR 1.05; 95% CI 0.97 to 1.14). Although LOS was similar between groups, adjusted hospital charges were 4.0% greater (95% CI 2.3 to 5.8%) for patients hospitalized on the weekend. CONCLUSIONS In patients with EVH, admission on the weekend is associated with a small delay in receiving endoscopic intervention, but no difference in mortality or the requirement for portosystemic shunt insertion. The weekend effect observed for some medical and surgical conditions does not apply to patients with EVH.

Abstract
BACKGROUND Although hospital admissions during weekends have been associated with worse quality of care and worse outcomes in some but not all medical conditions, the impact of weekend versus weekday admission and discharge for heart failure (HF) has not been well studied. This study investigates the association of (1) weekend compared to weekday HF admissions and discharges with quality of care and (2) weekend versus weekday HF admissions with length of stay (LOS) and mortality in the hospital. METHODS Data were analyzed for 81,810 HF admissions at 241 sites participating in Get With the Guidelines (GWTG)-HF from January 2005 to September 2008. The cohort was stratified by weekend versus weekday admission and discharge. Generalized estimating equations adjusted for patient and hospital characteristics and clustering. RESULTS Mean age was 72 +/- 14 years; left ventricular ejection fraction (LVEF) was 39+/-17%. Inhospital mortality was 3.0% and median LOS 4 days. Weekend admission was associated with decreased odds of LVEF documentation. Weekend discharge was associated with decreased odds of LVEF documentation and completed discharge instructions. Weekend HF admission compared to weekday admission was associated with slightly higher risk-adjusted odds of longer inhospital LOS (1.03 [1.01-1.05] and increased inhospital mortality (1.13 [1.02-1.27]). CONCLUSIONS Among GWTG-HF hospitals, weekend admission and discharge for HF were associated with similar quality of care in many but not all measures. Risk-adjusted LOS was slightly longer and mortality moderately higher for weekend HF admissions.

Abstract
STUDY OBJECTIVE Most patients are admitted to the hospital through the emergency department (ED), and ED waiting times partly reflect the availability of inpatient beds. We test whether the balance between daily hospital admissions and discharges affects next-day ED length of stay. METHODS We conducted a cross-sectional study of hospitals in metropolitan Toronto, served by a single emergency medical services provider in a publicly funded system. During a 3-year period, we evaluated the daily ratio of admissions to discharges at each hospital and the next-day median ED length of stay in the same hospital by using linear regression. RESULTS Across hospitals, the daily mean (SD) 50th percentile ED length of stay averaged 218 (51) minutes. As the inpatient admission-discharge ratio increased or decreased, next-day ED length of stay changed accordingly. Compared with ratios of 1.0, those less than 0.6 were associated with an 11-minute (95% confidence interval [CI] 5 to 16 minutes) shorter next-day median ED length of stay; at admission-discharge ratios of 1.3 to 1.4, ED length of stay was significantly prolonged by 5 minutes (95% CI 3 to 6 minutes). Admission-discharge ratios on weekends and among medical inpatients had a stronger influence on next-day ED length of stay; effects were also greater among higher-acuity and admitted ED patients. CONCLUSION Disequilibrium between the number of admitted and discharged inpatients significantly affects next-day ED length of stay. Better matching of daily hospital discharges and admissions could reduce ED waiting times and may be more amenable to intervention than reducing admissions alone. The admission-discharge ratio may also provide a simple way of tracking and enhancing hospital system performance.

Abstract
BACKGROUND & AIMS Management of upper gastrointestinal bleeding (UGIB) often requires urgent endoscopic intervention; limitations in its availability on weekends might be associated with increased mortality, compared with patients admitted on weekdays. METHODS We used the 1993-2005 U.S. Nationwide Inpatient Sample to identify patients hospitalized for UGIB caused by peptic ulceration. Differences in in-hospital mortality between patients admitted on weekends and weekdays were evaluated by using logistic regression models, adjusting for patient and clinical factors including the timing of upper endoscopy. RESULTS Between 1993 and 2005, there were 237,412 admissions to 3,166 hospitals for peptic ulcer-related UGIB. Compared with patients admitted on a weekday, those admitted on the weekend had an increased risk of death (3.4% vs 3.0%; adjusted odds ratio [OR], 1.08; 95% confidence interval [CI], 1.02-1.15), higher rates of surgical intervention (3.4% vs 3.1%; OR, 1.09; 95% CI, 1.03-1.15), prolonged hospital stays, and increased hospital charges (P < .0001 for all comparisons). Patients admitted on the weekend had a longer mean time to endoscopy (2.21 +/- 0.01 vs 2.06 +/- 0.01 days; P < .0001) and were less likely to undergo endoscopy on the day of admission (30% vs 34%; P < .0001). After adjusting for the timing of endoscopy, weekend admission remained an independent predictor of increased mortality (OR, 1.12; 95% CI, 1.05-1.20). CONCLUSIONS Patients admitted to hospital on the weekend for peptic ulcer-related hemorrhage have higher mortality and more frequently undergo surgery. Although wait times for endoscopy are prolonged in patients hospitalized on the weekend, this delay does not appear to mediate the weekend effect for mortality.

Abstract
BACKGROUND & AIMS Previous studies have identified a weekend effect in outcomes of patients with various medical conditions suggesting worse outcomes for weekend admissions. The aim of our study was to analyze if weekend admissions for upper gastrointestinal hemorrhage (UGIH) have higher mortality and longer hospital stay compared with those admitted on weekdays, and to examine if this effect differs by hospital teaching status. METHODS This was a cross-sectional study using the Nationwide Inpatient Sample 2004. A total of 28,820 discharges with acute variceal hemorrhage (AVH) and 391,119 discharges with acute nonvariceal UGIH (NVUGIH) were identified through appropriate International Classification of Diseases, ninth edition codes. Admissions were considered to be weekend admissions if they were admitted between midnight on Friday through midnight on Sunday. In-hospital mortality, frequency, and timing of endoscopy were measured. RESULTS On multivariate analysis, NVUGIH patients admitted on weekends had higher adjusted in-hospital mortality (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.09-1.35) and were less likely to undergo early endoscopy within 1 day of hospitalization (OR, 0.64; 95% CI, 0.61-0.68). Weekend admission was not predictive of in-hospital mortality in patients with AVH (OR, 0.94; 95% CI, 0.75-1.18), but was associated with lower likelihood of early endoscopy in nonteaching hospitals (OR, 0.65; 95% CI, 0.51-0.82). Early endoscopy was associated with significantly shorter hospital stays (NVUGIH, -1.08 days; AVH, -2.35 days) and lower hospitalization charges (NVUGIH, -$1958; AVH, -$8870). CONCLUSIONS Patients with NVUGIH admitted on the weekend had higher mortality and lower rates of early endoscopy. Patient with AVH admitted to nonteaching hospitals also had lower utilization of early endoscopy, but no difference in survival. There is a need for research into identifying the reasons for the weekend effect.
