Abbreviations: OR Odds ratio; se Standard error; CCI Charlson Comorbidity Index; HADx Hospital-acquired diagnosis. Models comprise components shown. Model 2 contains all variables without restriction and is the same as Model 2 in Table 2; Model 3 is restricted to those with no prior admission; Model 4 is restricted to the first admission only; Model 5 is limited to those with no prior admission & first admission only; Model 6 is Model 5 limited to those people older than 80 years (the median age of the cohort)
