Reducing readmission rates is a critical goal in population health management, as it reflects effective care coordination and patient outcomes post-discharge. Transition of care programs are specifically designed to ensure continuity of care as patients move between different healthcare settings (e.g., from hospital to home or skilled nursing facilities). These programs typically include interventions such as medication reconciliation, patient education, follow-up appointments, and communication between providers, all of which directly address factors contributing to readmissions.

Option A (Creation of disease registries): While disease registries are valuable for tracking patients with specific conditions and identifying trends, they are primarily a data management tool and do not directly address the processes needed to prevent readmissions. They are more supportive of long-term population health strategies rather than immediate care transitions.

Option B (Local resource directory): A local resource directory can help connect patients to community services, but it is not a structured intervention to manage care transitions or reduce readmissions. It is a supplementary tool rather than a primary solution.

Option C (Transition of care programs): According to NAHQ CPHQ study materials, transition of care programs are evidence-based interventions that reduce readmissions by ensuring effective handoffs, patient follow-up, and care coordination. Programs like the Transitional Care Model (TCM) or Project BOOST (Better Outcomes by Optimizing Safe Transitions) emphasize structured discharge planning, which aligns with CMS and Joint Commission standards for reducing readmissions. This makes it the most important and direct intervention for this goal.

Option D (Health information exchange): Health information exchanges (HIEs) facilitate data sharing between providers, which can support care transitions. However, HIEs are a tool to enable communication rather than a comprehensive program addressing the multifaceted causes of readmissions, such as patient education or follow-up care.
