The primary aim of this study was to determine outcomes for older patients cared for by geriatricians compared with non-geriatrician-led care team. Methods. Retrospective cohort study of 1,486 Internal Medicine patients aged ≥ 75 years admitted between April and September 2021 was conducted. They were either under geriatrician or non-geriatrician (internists or specialty physicians) care. Data on demographics, primary diagnosis, comorbidities, mortality, readmission rate, Hospital Frailty Risk Score, Age-adjusted Charlson Comorbidity Index, Length of Stay (LOS) and cost of hospital stay were obtained from hospital database and analyzed. Results. The mean age of patients was 84.0 ± 6.3 years, 860 (57.9%) females, 1,183 (79.6%) of Chinese ethnicity and 902 (60.7%) under the care of geriatricians. Patients under geriatrician were significantly older and had higher prevalence of frailty, dementia and stroke, whereas patients under non-geriatrician had higher prevalence of diabetes and hypertension. Delirium as primary diagnosis was significantly higher amongst patients under geriatrician care. Geriatrician-led care model was associated with shorter LOS, lower cost, similar inpatient mortality and 30-day readmission rates but significantly higher 30-day mortality rates. LOS and cost were lower for patients under geriatrician care regardless of frailty status but significant only for low and intermediate frailty groups. Geriatrician-led care was associated with significantly lower extended hospital stay (OR 0.73; 95% CI 0.56 – 0.95) and extended cost (OR 0.69; 95% CI 0.54 – 0.95). Conclusion. Geriatrician-led care model showed shorter LOS, lower cost and associated with lower odds of extended LOS and cost.
