Vel of medical presence (at least 2 intensivists and two residents). Patients admitted throughout onhours had been considered as reference group. Offhour admissions included nighttime (6:00 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. During offhours, healthcare team was lowered and integrated 1 intensivist and one resident.Study populationAll individuals older than PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/29046637 8 years consecutively admitted to the ICU over 9year period from January 2006 to December 204 had been included in the study. Patients who had to undergo a limitation of therapeutic effort (LTE) in the course of 
their ICU keep have been excluded from the evaluation. Only the very first ICU admission of every single patient was included. Data were prospectively collected and reported in a computer Excel spread sheet database. They had been recorded on a daily basis by the intensivist in charge of your patient. Information accuracy and exhaustiveness have been checked ahead of archiving paper folders. Information have been analysed and stored in an anonymous way and aren’t traceable to any patient. The Institutional Evaluation Board (Comite de protection des personnes: CPP CHU Montpellier) authorized the study and waived the will need for informed consent.Information collectionThe following data were extracted for each and every patient: age and sex, time and date of ICU admission, explanation for admission, and Physique Mass Index (BMI). Severity on the disease was assessed 24 hours following admission applying 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 remain (LOS) and ICU survival had been recorded. ICU mortality was the major end point on the study.Statistical analysisThe statistical analyses were performed using the R 2.five. (The R Foundation for Statistical Computing, Vienna, Austria) software program. We first performed a descriptive analysis by computing frequencies and percentages for categorial data; and implies or medians, regular deviations, quartiles and intense values for continuous data. We also checked for the normality of the continuous information distribution employing the ShapiroWilk’s tests. Continuous variables had been compared working with twotailed Student ttest or twotailed MannWhitneyWilcoxon’s test when proper. Fisher exact and Chi two tests have been utilised to evaluate categorial variables. To analyzePLOS 1 DOI:0.37journal.pone.068548 December 29,3 Mortality Connected with Night and Weekend Admissions to ICUthe elements connected with the inICU survival, the Cox proportional hazards regression model was utilised in both BMS-687453 cost univariate and multivariate models. ICU survival was calculated from the time of admission for the date of death from any result in or the date of ICU discharge. A certain possible association amongst time of admission and ICU survival was investigated. The proportional hazard assumption was tested and met for each and every variable of interest. Results had been expressed as hazard ratios and 95 confidence intervals. Survival curves were generated using the KaplanMeier methodology. A value of p 0.05 was deemed as considerable.ResultsDuring the study period, 2,894 patients were admitted towards the ICU. Right after the exclusion of 464 sufferers (6 ) who underwent a LTE, and two sufferers for missing data, 2,428 patients had been enrolled inside the study. The study flowchart is shown in Fig . Amongst the population analysed, 680 (28 ) sufferers have been admitted.
