Introducing Goals of Patient Care in Residential Aged Care Facilities to Decrease Hospitalization: A Cluster Randomized Controlled Trial.

Abstract

Abstract OBJECTIVES: The "Goals of Patient Care" (GOPC) process uses shared decision making to incorporate residents' prior advance care planning (ACP) or preferences into medical treatment orders, guiding health care decisions at a time of clinical deterioration should they be unable to voice their opinions. The objective was to determine whether GOPC medical treatment orders were more effective than ACP alone in preventing emergency department (ED) visits (no hospitalization), ED visits (with hospitalization), and deaths outside the residential aged care facility (RACF). DESIGN: The study was a prospective cluster randomized controlled trial, with the intervention being the completion of GOPC process by a geriatrician, following a shared decision-making process, incorporating ACP documents or residents' preferences. SETTING AND PARTICIPANTS: The study took place in 6 RACFs in Northern Metropolitan Melbourne, Australia. Eligible participants included all permanent residents in participating RACFs for whom written informed consent could be obtained. MEASURES: The primary outcome was the effect on ED visits and hospitalizations at 6 months. Secondary outcomes included a difference in hospitalization rates at 3 and 12 months, total hospital bed-days, and in-RACF and in-hospital mortality rates. RESULTS: More than 75% of residents participated, 181 randomized to Intervention and 145 to Control. The intervention did not result in a statistically significant change at 6 months; however, at 12 months, it reached statistical significance with 40% reduction in ED visits and hospitalizations compared with Control, with an incident rate ratio 0.63 [95% confidence interval (CI) 0.41-0.99, P = .044]. Mortality rates show increased likelihood of dying in the RACF, with statistical significance at 6 months at a relative risk ratio of 2.19 (95% CI 1.16-4.14, P = .016). CONCLUSIONS AND IMPLICATIONS: In the RACF population, GOPC medical treatment orders were more effective than ACP alone for decreasing hospitalization and likelihood of dying outside the RACF. GOPC should be considered by both RACF staff and health services to decrease hospitalization and in-hospital mortality.
