Vel of purchase ML281 medical presence (at least 2 intensivists and two residents). Individuals admitted through onhours had been deemed as reference group. Offhour admissions included nighttime (six:00 p.m. to 7:59 a.m.), weekend (from Saturday 08:00 a.m. to Monday 7:59 a.m.) and holidays’ admissions. Holidays were those officially recognised by the French Republic. Through offhours, medical team was reduced and included one particular intensivist and one particular resident.Study populationAll individuals older than PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/29046637 eight years consecutively admitted for the ICU over 9year period from January 2006 to December 204 have been included inside the study. Patients who had to undergo a limitation of therapeutic effort (LTE) during their ICU stay have been excluded from the analysis. Only the very first ICU admission of every patient was integrated. Information had been prospectively collected and reported within a computer Excel spread sheet database. They were recorded every day by the intensivist in charge on the patient. Information accuracy and exhaustiveness were checked ahead of archiving paper folders. Data have been analysed and stored in an anonymous way and usually are not traceable to any patient. The Institutional Assessment Board (Comite de protection des personnes: CPP CHU Montpellier) authorized the study and waived the need for informed consent.Information collectionThe following data had been extracted for every patient: age and sex, time and date of ICU admission, purpose for admission, and Body Mass Index (BMI). Severity of the illness was assessed 24 hours after admission working with the simplified acute physiology score (SAPS) II [20]. The requirement for invasive mechanical ventilation, renal replacement therapy (RRT) and for vasoconstrictive agents was recorded. ICU length of stay (LOS) and ICU survival have been recorded. ICU mortality was the main end point in the study.Statistical analysisThe statistical analyses were performed working with the R 2.five. (The R Foundation for Statistical Computing, Vienna, Austria) computer software. We very first performed a descriptive analysis by computing frequencies and percentages for categorial information; and implies or medians, regular deviations, quartiles and intense values for continuous information. We also checked for the normality in the continuous data distribution using the ShapiroWilk’s tests. Continuous variables have been compared making use of twotailed Student ttest or twotailed MannWhitneyWilcoxon’s test when acceptable. Fisher exact and Chi 2 tests were employed to compare categorial variables. To analyzePLOS One DOI:0.37journal.pone.068548 December 29,three Mortality Related with Night and Weekend Admissions to ICUthe elements connected with all the inICU survival, the Cox proportional hazards regression model was made use of in both univariate and multivariate models. ICU survival was calculated in the time of admission for the date of death from any bring about or the date of ICU discharge. A specific potential association among time of admission and ICU survival was investigated. The proportional hazard assumption was tested and met for every single variable of interest. Benefits were expressed as hazard ratios and 95 confidence intervals. Survival curves were generated working with the KaplanMeier methodology. A value of p 0.05 was deemed as important.ResultsDuring the study period, 2,894 patients have been admitted towards the ICU. Soon after the exclusion of 464 individuals (six ) who underwent a LTE, and two individuals for missing data, 2,428 patients were enrolled in the study. The study flowchart is shown in Fig . Amongst the population analysed, 680 (28 ) individuals have been admitted.
