ABSTRACT
INTRODUCTION: Singapore faces an increasingly aged population with complex multimorbidity and psychosocial impairment. This change in demographic is challenging for existing healthcare systems. Breaks in care coordination and continuity result in poor health outcomes, increased acute care utilisation and higher healthcare costs. We proposed a patient empanelment approach adapted for the Singapore context based on the University of Chicago Comprehensive Care Physician model. METHODS: This retrospective quasi-experimental, matched-controlled observational study sought to assess the effectiveness of the Enhanced Comprehensive Care Programme (ECCP) in reducing acute care utilisation at National University Hospital, Singapore. The primary outcomes were the number of hospitalisations and emergency department (ED) visits 6 months pre- and post-enrolment in ECCP. We used propensity score matching to balance prior healthcare utilisation between the intervention and control groups. RESULTS: Fifty-seven participants were recruited in the programme between October 2019 and April 2020. There was a reduction in the mean number of hospitalisations after intervention compared to before intervention (0.58 ± 1.03 vs. 1.90 ± 1.07, P < 0.001). There was also a reduction in the mean number of ED visits (0.77 ± 1.05 vs. 1.96 ± 1.14, P < 0.001). In the propensity-matched cohort, the mean number of hospitalisations was reduced in the intervention group (from 1.92 ± 1.07 to 0.58 ± 1.03, P < 0.001) compared to the control group (from 1.85 ± 0.99 to 1.06 ± 1.17, P = 0.04). CONCLUSION: This observational study shows the potential benefits of ECCP healthcare redesign to reduce acute care utilisation.
