If we adjusted for age, gender, pre-admission residence type, type of admission (emergency or not), Charlson co-morbidity index, type of service, and ICU stay, these differences were less pronounced, but still highly significant (adjusted mortality OR (95% CI): 3.18 (2.79 to 3.63), p < 0.001; adjusted HR (95% CI) for ICU discharge: 0.39 (0.36 to 0.41), p < 0.001; adjusted HR (95% CI) for hospital discharge: 0.43 (0.41 to 0.45), p < 0.001; adjusted median difference nursing hours (95% CI): 37.3 (35.0 to 39.5), p < 0.001; adjusted median cost difference [in thousand CHF] (95% CI): 10.0 (9.3 to 10.6), < 0.001).
