*Multivariable regression: 1-week data set: C reactive protein (CRP), white cell count (WCC) and Charlson score independently associated with 30-day mortality. Sepsis, Charlson score and admission with a frailty syndrome independently associated with adverse composite outcome. Charlson score, age and later time of day independently associated with admission. Charlson score, age, presentation with a frailty syndrome, community antibiotics, WCC and admission during a weekday independently associated with longer length of stay. Three-year data set: Charlson score, age, male gender and non-weekday admission independently associated with mortality, Charlson score, age hour of admission and non-weekday admission independently associated with admission overnight, Charlson score, female, age, hour of admission and non-weekday admission independently associated with longer length of stay.
