Sustainability of Evidence-Based Practice Improvement Programs in Abu Dhabi Ambulatory Healthcare Services for more than a decade and During the COVID-19 Pandemic

The Abu Dhabi Ambulatory Healthcare Services (AHS) implemented the Chronic Disease Care (CDC) and Patient-Centered Medical Home (PCMH) programs. A retrospective observational descriptive design was used to analyze the sustainability of both programs. Linear regression showed that the key performance indicator (KPI) for the best-performing centers had significantly higher PCMH scores, with no effect on the financial revenue of the centers. Pearson correlation analysis indicated significant correlations between clinical and preventive KPI achievements and the 2022 PCMH and CDC scores. The AHS centers successfully implemented both programs sustainably. The study findings highlight areas for sustainability research that demonstrate the value of sustainable interventions. Contributions to the literatureO_LIDeviations in achieving optimal healthcare outcomes are rooted in the lack of enough evidence-based interventions. C_LIO_LIEvidence-based interventions, like providing family medicine-based primary care, rank among the most thoroughly studied interventions. C_LIO_LIThis study demonstrates the sustainability of the well-known, evidence-based intervention, NCQA PCMH standards. C_LIO_LIThe established structure and processes for adapting the NCQA PCMH standards supported AHS centers during and after the COVID-19 pandemic, resulting in superior clinical and utilization outcomes in centers that implemented the standards more effectively.
