A Coaching by Telephone Intervention on Engaging Patients to Address Modifiable Cardiovascular Risk Factors: a Randomized Controlled Trial.

Abstract

A large proportion of deaths and chronic illnesses can be attributed to three modifiable risk factors: tobacco use, overweight/obesity, and physical inactivity. To test whether telephone-based health coaching after completion of a comprehensive health risk assessment (HRA) increases patient activation and enrollment in a prevention program compared to HRA completion alone. Two-arm randomized trial at three sites. Primary care clinics at Veterans Affairs facilities. Four hundred seventeen veterans with at least one modifiable risk factor (BMI ≥ 30, < 150 min of at least moderate physically activity per week, or current smoker). Participants completed an online HRA. Intervention participants received two telephone-delivered health coaching calls at 1 and 4 weeks to collaboratively set goals to enroll in, and attend structured prevention programs designed to reduce modifiable risk factors. Primary outcome was enrollment in a structured prevention program by 6 months. Secondary outcomes were Patient Activation Measure (PAM) and Framingham Risk Score (FRS). Most participants were male (85%), white (50%), with a mean age of 56. Participants were eligible, because their BMI was ≥ 30 (80%), they were physically inactive (50%), and/or they were current smokers (39%). When compared to HLA only at 6 months, health coaching intervention participants reported higher rates of enrollment in a prevention program, 51 vs 29% (OR = 2.5; 95% CI: 1.7, 3.9; p < 0.0001), higher rates of program participation, 40 vs 23% (OR = 2.3; 95% CI: 1.5, 3.6; p = 0.0004), and greater improvement in PAM scores, mean difference 2.5 (95% CI: 0.2, 4.7; p = 0.03), but no change in FRS scores, mean difference 0.7 (95% CI - 0.7, 2.2; p = 0.33). Brief telephone health coaching after completing an online HRA increased patient activation and increased enrollment in structured prevention programs to improve health behaviors. CLINICALTRIALS.
