Paramedic-led intervention cuts ambulance calls
Gina Agarwal, Ph.D., from McMaster University in Hamilton, Canada, and colleagues conducted an open-label pragmatic cluster-randomized controlled trial in subsidized apartment buildings for older adults. Six buildings were randomized to either intervention (CP@clinic; three buildings) for one year or control (usual health care; three buildings). The intervention and control buildings had 455 and 637 residents, respectively.
The researchers found that, compared with the control buildings, the three intervention buildings had significantly lower mean monthly ambulance calls (3.11 versus 3.99 calls per 100 units/month; mean difference, −0.88) when adjusted for baseline calls and building pairs. Significant improvement was seen in QALYs (mean difference, 0.09) and ability to perform usual activities (odds ratio, 2.6) for residents living in the intervention buildings versus the control buildings. A significant decrease was seen in diastolic blood pressure for those who received the intervention (mean change, 4.8 mm Hg).
"In the coming decades, the growing population of older adults will affect the Canadian health system inevitably, and the CP@clinic program has great potential to reduce the impending burden created by this evolving demographic," the authors write.
