- Brief Summary
This feasibility trial will focus on older adults 60+ who are candidates for cardiac or pulmonary rehabilitation and who are vulnerable, mildly or moderately frail. We will randomize older frail adults living in rural regions of the county to Treatment as usual (TAU) or Stepped care (SC). TAU refers to center-based rehabilitation (CBR). Patients randomized to SC will be enrolled in traditional CBR and based on prespecified non-response criteria, will step up to three services: 1) Transportation-subsidized CBR, 2) Home-based telerehabilitation (TR), and 3) Community health worker-(CHW) supported home-based TR.
- Detailed Description
Cardiac rehabilitation (CR) decreases mortality and both CR and pulmonary rehabilitation (PR) improve function, quality of life, and decrease readmission rates. Despite their proven efficacy, both programs are grossly underutilized, with fewer than 20% of eligible persons participating. Patients with heart and lung disease living in rural communities have even lower rates of participation.
The objective of this proposal is to test the feasibility of performing a full-scale randomized controlled trial (RCT) to compare the effectiveness and value of a stepped care (SC) model versus treatment as usual (TAU) in older frail adults living rural counties. TAU refers to center-based rehabilitation (CBR). The SC model includes initial enrollment into CBR followed by possible step up to three interventions based on prespecified non-response criteria: 1) Transportation-subsidized CBR, 2) Home-based telerehabilitation (TR), and 3) Community health worker-(CHW) supported home-based TR. Unlike traditional SC models, the initial treatment in this model, i.e. CBR, is not the least resource intensive. CBR was chosen as the initial option because it is currently considered the standard of care.
We will conduct a parallel, 2-arm, randomized controlled feasibility trial. Eligible participants will be randomized to TAU (CBR) or SC. Because of the urgent need to address underuse of both CR and PR in rural regions, the proposed feasibility trial will enroll patients referred to either CR or PR. Both arms include an in-person intake evaluation conducted by a certified rehabilitation nurse in the rehabilitation center to determine exercise tolerance and design a tailored 8-week rehabilitation program. Patients randomized to TAU participate in two weekly sessions at the center and are encouraged to exercise at home in between sessions. Patients randomized to the SC arm will also be enrolled in the CBR program. Those who meet prespecified non-response criteria will be stepped up to transportation-subsidized CBR. Providing transportation may not be sufficient for frail older adults who are reluctant to leave their homes in the winter, unfamiliar with exercising, or do not want to exercise in a group setting. Thus, non-responders, will be stepped up to home-based TR. Home-based rehabilitation will be supported by Chanl Health, a virtual platform that supports education and self-management, remote monitoring, and coaching by rehabilitation specialists. Non-responders will be stepped up to CHW-supported home-based TR. The CHW will be help participants use the mobile app, access educational materials, clarify educational content, and exercise during biweekly in-person visits.
Purpose: Heart and lung disease are the first and third leading causes of mortality in the US, respectively. Cardiac rehabilitation (CR) decreases mortality and both CR and pulmonary rehabilitation (PR) improve function, quality of life, and decrease readmission rates. Despite their proven efficacy, both programs are grossly underutilized, with fewer than 20% of eligible persons participating. Patients living in rural communities have even lower rates of participation. Home-based CR and PR has been developed with the goal of improving uptake, and low to moderate strength evidence indicates that these programs are as effective as center-based programs. Further work is needed, however, to examine how best to increase utilization of CR and PR in rural communities. While several studies have examined approaches to improve referral and enrollment, there is little evidence on how to optimize adherence to CR, and no evidence how to optimize adherence to PR.
