Personalized Physician Learning to Improve Hypertension Care

In this project the investigators implement and test the ability of a Personalized Physician Learning (PPL) intervention to improve hypertension (HT) care with the following specific aims: Specific Aim 1: Implement two versions of a Personalized Physician Learning (PPL) intervention and assess the ability of these interventions to improve hypertension control in primary care practice. * Hypothesis 1: Patients of physicians who receive the REAL+PPL Intervention (Group 1) will subsequently have better HT control compared to patients of control group physicians (Group 3). * Hypothesis 2: Patients of physicians who receive the SIM+PPL Intervention (Group 2) will subsequently have better HT control compared to patients of control group physicians (Group 3). * Hypothesis 3: Patients of physicians who receive the REAL+PPL (Group 1) will subsequently have better HT control compared to patients of physicians who receive the SIM+PPL (Group 2). Specific Aim 2: Assess the cost-effectiveness of the SIM+PPL and REAL+PPL interventions, relative to no intervention.
