933 FACTORS ASSOCIATED WITH LENGTH OF STAY ON OLDER PEOPLE’S MEDICINE WARDS

Abstract Introduction The Newcastle upon Tyne Hospitals NHS Foundation Trust’s Older People’s Medicine (OPM) department includes six inpatient wards. It was hypothesized that an increasing prevalence of inpatient frailty would be associated with increased length of stay. Method Data were collected on OPM wards, on a single day of February 2020 and July 2021. Demographic details, mobility, presence of delirium, resuscitation status, length of stay (LOS), and Clinical Frailty Scale (CFS) status was recorded (frailty defined as CFS score ≥ 5). Descriptive statistics and tests of significance comparing 2020 with 2021 data were performed. Independent associations with above-median LOS were analysed using binary logistic regression. Results There were 172 inpatients in 2020, and 160 in 2021. Median age was 84 (range 66–98 years) in 2020, and 85 (range 64–99 years) in 2021. 87 (54.4%) in 2021, and 102 (59.3%) in 2020 were female. Prevalence of pre-admission frailty was higher in 2021 (n = 143, 89.4%) compared to 2020 (n = 125, 72.7%, p
