Converting acute inpatient take to outpatient take with fast-track assessment in internal medicine wards – a before-after study

Table 3 Unadjusted and adjusted likelihood (prevalence proportion ratio (PPR)) of having a hospital length-of-stay longer than 24, 72 and 7 days, admission, length-of-admission-time longer than 24, 72 and 7 days, re-contact within 30 days, readmission, contact to GP within 30 days, and mortality within 30 days after comparing before and after the intervention (1st March 2017)

^aHospital length-of-stay: the time from arrival to departing either as outpatient or by discharge. Length-of-admission time: the time from admission to the time of discharge Dichotomised at 24 hours, 72 hours and 7 days, the likelihood of having a length-of-stay longer than 24 hours, 72 hours, and 7 days.
^bAdjusted for gender, age and triage score
