Higher mortality rates amongst emergency patients admitted to hospital at weekends reflect a lower probability of admission.

ABSTRACT: Objective Patients admitted as emergencies to hospitals at the weekend have higher death rates than patients admitted on weekdays. This may be because the restricted service availability at weekends leads to selection of patients with greater average severity of illness. We examined volumes and rates of hospital admissions and deaths across the week for patients presenting to emergency services through two routes: (a) hospital Accident and Emergency departments, which are open throughout the week; and (b) services in the community, for which availability is more restricted at weekends. Method Retrospective observational study of all 140 non-specialist acute hospital Trusts in England analyzing 12,670,788 Accident and Emergency attendances and 4,656,586 emergency admissions (940,859 direct admissions from primary care and 3,715,727 admissions through Accident and Emergency) between April 2013 and February 2014.Emergency attendances and admissions to hospital and deaths in any hospital within 30 days of attendance or admission were compared for weekdays and weekends. Results Similar numbers of patients attended Accident and Emergency on weekends and weekdays. There were similar numbers of deaths amongst patients attending Accident and Emergency on weekend days compared with weekdays (378.0 vs. 388.3). Attending Accident and Emergency at the weekend was not associated with a significantly higher probability of death (risk-adjusted OR: 1.010). Proportionately fewer patients who attended Accident and Emergency at weekend were admitted to hospital (27.5% vs. 30.0%) and it is only amongst the subset of patients attending Accident and Emergency who were selected for admission to hospital that the probability of dying was significantly higher at the weekend (risk-adjusted OR: 1.054). The average volume of direct admissions from services in the community was 61% lower on weekend days compared to weekdays (1317 vs. 3404). There were fewer deaths following direct admission on weekend days than weekdays (35.9 vs. 80.8). The mortality rate was significantly higher at weekends amongst direct admissions (risk-adjusted OR: 1.212) due to the proportionately greater reduction in admissions relative to deaths. Conclusions There are fewer deaths following hospital admission at weekends. Higher mortality rates at weekends are found only amongst the subset of patients who are admitted. The reduced availability of primary care services and the higher Accident and Emergency admission threshold at weekends mean fewer and sicker patients are admitted at weekends than during the week. Extending services in hospitals and in the community at weekends may increase the number of emergency admissions and therefore lower mortality, but may not reduce the absolute number of deaths.

Project description:Hospital admissions over weekends have been associated with worse outcomes in different patient populations. The cause of this difference in outcomes remains unclear; however, different staffing patterns over weekends have been speculated to contribute. We evaluated outcomes in patients on maintenance dialysis therapy admitted over weekends using a national database.Retrospective cohort study.We included nonelective admissions of adult patients (?18 years) on maintenance dialysis therapy (n = 3,278,572) identified using appropriate International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for 2005-2009 using the Nationwide Inpatient Sample database.Weekend versus weekday admission.The primary outcome measure was all-cause in-hospital mortality. Secondary outcomes included mortality by day 3 of admission, length of hospital stay, time to death, and discharge disposition.We adjusted for patient and hospital characteristics, payer, year, comorbid conditions, and primary discharge diagnosis common to maintenance dialysis patients.There were an estimated 704,491 admissions over weekends versus 2,574,081 over weekdays. Unadjusted all-cause in-hospital mortality was 40,666 (5.8%) for weekend admissions in comparison to 138,517 (5.4%) for weekday admissions (P < 0.001). In a multivariable model, patients admitted over weekends had higher all-cause in-hospital mortality (OR, 1.06; 95% CI, 1.01-1.10) in comparison to those admitted over weekdays and higher mortality during the first 3 days of admission (OR, 1.18; 95% CI, 1.10-1.26). Patients admitted over weekends were less likely to be discharged to home, had longer hospital stays, and had shorter times to death compared with those admitted over weekdays on adjusted analysis.Use of ICD-9-CM codes to identify patients, defining weekend as midnight Friday to midnight Sunday.Maintenance dialysis patients admitted over weekends have increased mortality rates and longer lengths of stay compared with those admitted over weekdays. Further studies are needed to identify the reasons for worse outcomes for weekend admissions in this patient population.

Project description:OBJECTIVES:Chronic respiratory diseases exert a global health burden with high health care costs, morbidity, and mortality. The aim of the present study was to investigate the effect of pulmonary rehabilitation (PR) on emergency admission and hospitalization rates of patients with chronic respiratory disease. MATERIALS AND METHODS:In this retrospective cohort study, hospitalization rates and emergency admissions of patients before (December 2014-December 2015) and after PR (January 2015-December 2016) were investigated. Patients with chronic respiratory diseases were included. Chronic obstructive pulmonary disease (COPD) patients were classified based on the Global Initiative Chronic Obstructive Pulmonary Disease assessment scheme. PR was applied by three physiotherapists over 8 weeks (2 days/week). Data on patient demographics, clinical and anthropometric data, spirometry, exercise capacity, and quality of life before and after PR were acquired. RESULTS:This study evaluated 51 patients, of whom 76% were men. A total of 37 (73%) COPD patients and 14 (27%) non-COPD patients (7 bronchiectasis, 4 interstitial lung disease, and 3 kyphoscoliosis) were included. The patients exhibited significantly improved incremental shuttle walk test (ISWT) and endurance test scores (p<0.05) after PR. Similar to exercise capacity, the patients exhibited significantly improved Modified Medical Research Council (mMRC) score, St. George's Respiratory Questionnaire (SGRQ), anxiety and depression scores (p<0.05) after PR. In COPD patients, differences in pre- and post-PR ISWT, COPD assessment test, mMRC, and SGRQ scores were statistically significant (p=0.001). The number of emergency admissions and hospitalizations significantly decreased after PR (p=0.001; p=0.001). The post-PR FEV1% of COPD significantly increased (p=0.029). CONCLUSION:Pulmonary rehabilitation leads to an increase in exercise capacity as well as improved quality of life, resulting in a decrease in emergency admissions and hospitalization rates. Considering the cost of hospitalization, it is important to add PR to the management of patients with chronic respiratory diseases, in addition to medical therapy.
