Integration of Inpatient and Residential Care In-Reach Service Model and Hospital Resource Utilization: A Retrospective Audit.

Abstract

In parts of Australia, Residential In-Reach (RIR) services have been implemented to treat residential aged care (RAC) residents for acute conditions in their place of residence to avoid preventable hospital presentation. Our service was initiated in 2009 and restructured in 2014. We compared acute healthcare resource utilization (RIR activity and emergency hospital presentations) by RAC residents under 2 RIR models of care. Acute RAC RIR service model of care was changed from existing nurse/emergency physician-led service to nurse/geriatrician-led service and incorporate inpatient liaison nurse consultant into the team. RAC episodes and hospital presentations from a single tertiary referral hospital and its associated RAC RIR service. Retrospective audit comparing RIR activity, hospital presentations, and associated costs from 2 12-month periods, prior to and postimplementation. Data were expressed as a proportion of the total number of RAC beds in the hospital RIR catchment. After implementation of the new model of care, RIR episodes of care increased from 589 to 985 (15.3 vs 24.7 episodes/100 RAC beds, P < .001). Emergency department (ED) presentations fell from 1616 to 1478 (41.9 vs 37.2 presentations/100 RAC beds, P < .001). There were fewer unplanned ED presentations by RIR patients (2.4% vs 0.8%, = 0.03) and fewer 28-day ED re-presentations (16.8% vs 13.7%, P = .01) under the new model of care. ED cost [$AUD 30,830 vs $28,030/100 RAC beds ($USD 21,344 vs $19,407), P < .001] and inpatient admission costs [$145,607 vs $117,531/100 RAC beds ($USD 100,814 vs $81,380), P < .001] were each lower in the second period. In the 12 months following implementation of the new model of care, an increase in RIR activity, and a decrease in ED presentations was observed. Further research is necessary to validate these retrospective findings and better evaluate clinical outcomes and consumer satisfaction of the service.
