Selection bias is possible if patients with incomplete episodes, such as those with prolonged hospital admission, had a differential mortality risk to those with completed episodes. Nevertheless, the size of our patient cohort compares favourably to other datasets for model creation. The patient cohort on which the 4C Mortality Score was derived comprised patients admitted to hospital who were seriously ill (mortality rate of 32.2%) and were of advanced age (median age 73 years). This model is not for use in the community and could perform differently in populations at lower risk of death. Further external validation is required to determine whether the 4C Mortality Score is generalisable among younger patients and in settings outside the UK."}
