Factors influencing implementation of personalized prevention plans among annual wellness visit patients using the theory of planned behavior: A quantitative study

Abstract

Background: The Affordable Care Act provides Medicare Part B beneficiaries access to cost-free Annual Wellness Visits (AWVs). Patients receive health behavior recommendations from a Personalized Prevention Plan (PPP) during AWV encounters. Aims: To identify factors clinical pharmacists can use to influence adoption of PPPs in primary care practices. Method: Utilizing a cross-sectional design, 77 Medicare patients (mean age 74.05 ± 8.04 years) presenting for subsequent AWV completed a theory of planned behavior (TPB) based questionnaire at two primary care practices. Results: 66.2% reported they were in the process of implementing PPPs and 51.9% reported implementing recommendations in the previous 12 months. TPB constructs accounted for 35.8% (p < .001) of the variation in intention, with subjective norm (SN) (β = 0.359, p = 0.004) as the strongest determinant, followed by attitude (β = 0.195, p = 0.093), and perceived behavioral control (PBC) (β = 0.103, p = 0.384). Intention accounted for 27.1% of the variance for implementing PPPs and was not a significant determinant (β = 0.047, p = 0.917). Addition of past behavior with TPB constructs significantly improved the predictability of the TPB model, accounted for 55% of the variation in intention (p < .001), and demonstrated a significant positive influence (β = 0.636, p < 0.001) on future PPP implementations. Discussion: This study demonstrates utility of the TPB in predicting implementation of PPPs. Conclusions. Clinical pharmacists positioned as providers of AWVs can strengthen intention to adopt PPPs by integrating referents into AWV processes, and evaluating past behavior trends to improve future PPP implementation.
