Patient receipt of recommended preventive and chronic disease care is suboptimal, partly because of poorly organized clinical information and time-limited and sporadic appointments with medical providers. To overcome these problems, we provide a Health Promotion Outreach System (HPOS) based on electronic data queries, active patient-centered outreach, and minimizing patient barriers to adherence. HPOS has many advantages over traditional preventive care delivery systems and chronic disease management programs, and helps promote the type of clinical practice change contemplated by the chronic care model.
