Table 1 Logistic regression predicting an in-hospital death (versus survival) by 30 days in acute medical patients admitted between 2002 and 2008

From: Reflections on off hour admissions to ICU

Admission type Odds ratio Lower CI Upper CI P-value
Respiratory (MDC 4) 2.13 1.69 2.67 <0.01
Circulatory (MDC 5) 1.96 1.49 2.57 <0.01
Nervous (MDC 1) 2.55 1.88 3.44 <0.01
Charlson Co-morbidity Index 1.32 1.23 1.42 <0.01
ICU stay 8.88 6.39 12.16 <0.01
Evening admission 1.39 1.15 1.67 <0.01
  1. Unit odds ratio adjusted for acute illness score; higher odds ratios indicate a higher likelihood of death; evening admission 16:00 to 00:00 (odds ratio versus 00:00 to 16:00).
