Few randomized trials have successfully improved the quality of medical care delivered to individuals with serious mental illnesses (8–10). Druss et al. have been at the forefront of this important area of research for a number of years and have been able to effectively improve the physical health services delivered to patients with serious mental illnesses using a variety of approaches, including peer support (11) and care management (12, 13). In their article in this issue of the Journal, Druss et al. (14) report the results of a technology-based patient-activation approach to improving physical health service delivery that builds upon their earlier achievements. Patients with serious mental illnesses were recruited from a community mental health center, and one-half were randomly assigned to be given access to a community-based personal health record. Theoretically, improving “digital access” (i.e., connectivity that enables patients to interact with providers, caregivers, peers, and computer applications such as personal health records) should improve treatment engagement, just as online shopping (e.g., Amazon) has increased market share in the retail industry (15). And in fact, patients given access to the personal health record received nearly twice the number of preventive services during the intervention period than they did the year before. These findings represent a major victory in the war against health disparities among individuals with serious mental illnesses. Importantly, a post hoc mediation analysis found that improvements in the quality of medical care were achieved through a substantial increase in the number of physical health outpatient encounters (14.9 visits) in the personal health record group. This finding suggests that increasing digital access to care can substantially improve patients’ engagement in physical health services, even for those with limited resources, computer skills, and health literacy.
