We aimed to determine if a community paramedicine program — in which paramedics provide health care services outside of the traditional emergency response — reduced the number of ambulance calls to subsidized housing for older adults.METHODS: We conducted an open-label pragmatic cluster-randomized controlled trial (RCT) with parallel intervention and control groups in subsidized apartment buildings for older adults. We selected 6 buildings using predefined criteria, which we then randomly assigned to intervention (Community Paramedicine at Clinic [CP@clinic] for 1 yr) or control (usual health care) using computer-generated paired randomization. CP@clinic is a paramedic-led, community-based health promotion program to prevent diabetes, cardiovascular disease and falls for residents 55 years of age and older. The primary outcome was building-level mean monthly ambulance calls. Secondary outcomes were individual-level changes in blood pressure, health behaviours and risk of diabetes assessed using the Canadian Diabetes Risk Questionnaire. We analyzed the data using generalized estimating equations and hierarchical linear modelling.RESULTS: The 3 intervention and 3 control buildings had 455 and 637 residents, respectively. Mean monthly ambulance calls in the intervention buildings (3.11 [standard deviation (SD) 1.30] calls per 100 units/mo) was significantly lower (−0.88, 95% confidence interval [CI] −0.45 to −1.30) than in control buildings (3.99 [SD 1.17] calls per 100 units/mo), when adjusted for baseline calls and building pairs. Survey participation was 28.4% (n = 129) and 20.3% (n = 129) in the intervention and control buildings, respectively. Residents living in the intervention buildings showed significant improvement compared with those living in control buildings in quality-adjusted life years (QALYs) (mean difference 0.09, 95% CI 0.01 to 0.17) and ability to perform usual activities (odds ratio 2.6, 95% CI 1.2 to 5.8). Those who received the intervention had a significant decrease in systolic (mean change 5.0, 95% CI 1.0 to 9.0) and diastolic (mean change 4.8, 95% CI 1.9 to 7.6) blood pressure.INTERPRETATION: A paramedic-led, community-based health promotion program (CP@clinic) significantly lowered the number of ambulance calls, improved QALYs and ability to perform usual activities, and lowered systolic blood pressure among older adults living in subsidized housing.
