Implementation of a remote behavioral intervention for older adults with asthma - a pilot study.

Abstract

Older adults with asthma (OAA) have elevated asthma morbidity rates. A six-session intervention based on self-regulation theory was shown to improve outcomes. However wide-spread implementation was difficult due to the in-person design. Our objective was to determine the feasibility and acceptability of an updated intervention for OAA that is completely remote, includes a physician component, and utilizes shared decision making (SDM). A pilot study of 12 OAA with uncontrolled asthma and their asthma providers was conducted at three health centers. The remote intervention (titled SOAR) consisted of 4 sessions (2 group and 2 individual). Asthma providers (both specialists and primary care) were sent updates of progress along with information on how to incorporate SDM into the visit. Implementation (feasibility, acceptability, and appropriateness) and clinical (asthma control, asthma quality of life, perceived control, depression, and self-confidence) outcomes were measured. SOAR was found to be feasible, acceptable, and appropriate, with values on validated implementation scales similar to those of in-person behavioral interventions. Asthma providers found the program helpful and intended to change care based on the updates. Asthma control scores improved significantly from baseline (14.2 to 16.8, p = 0.04), as did asthma quality of life (4.2 to 4.9, p = 0.03) and self-confidence to manage asthma (7.1 to 8.5, p = 0.02). There was no change in depression nor perceived control scores. A remote behavioral intervention appeared feasible and acceptable for OAA and their health care providers, and can improve outcomes. Larger scale implementation trials are warranted.
