Background:
Little is known about strategies to improve patient activation, particularly among persons living with HIV (PLWH).
Objective:
To assess the impact of a group intervention and individual coaching on patient activation for PLWH.
Design:
Pragmatic randomized controlled trial.
Sites:
Eight practices in New York and two in New Jersey serving PLWH.
Participants:
Three hundred sixty PLWH who received care at participating practices and had at least limited English proficiency and basic literacy.
Intervention:
Six 90-min group training sessions covering use of an ePersonal Health Record loaded onto a handheld mobile device and a single 20-30 min individual pre-visit coaching session.
Main Measures:
The primary outcome was change in Patient Activation Measure (PAM). Secondary outcomes were changes in eHealth literacy (eHEALS), Decision Self-efficacy (DSES), Perceived Involvement in Care Scale (PICS), health (SF-12), receipt of HIV-related care, and change in HIV viral load (VL).
Key Results:
The intervention group showed significantly greater improvement than the control group in the primary outcome, the PAM (difference 2.82: 95% confidence interval [CI] 0.32-5.32). Effects were largest among participants with lowest quartile PAM at baseline (p < 0.05). The intervention doubled the odds of improving one level on the PAM (odds ratio 1.96; 95% CI 1.16-3.31). The intervention group also had significantly greater improvement in eHEALS (difference 2.67: 95% CI 1.38-3.9) and PICS (1.27: 95% CI 0.41-2.13) than the control group. Intervention effects were similar by race/ethnicity and low education with the exception of eHealth literacy where effects were stronger for minority participants. No statistically significant effects were observed for decision self-efficacy, health status, adherence, receipt of HIV relevant care, or HIV viral load.
Conclusions:
The patient activation intervention modestly improved several domains related to patient empowerment; effects on patient activation were largest among those with the lowest levels of baseline patient activation.
