Electronic Medical Records (EMR) systems represented a transformative technology in healthcare service delivery, yet their implementation outcomes varied across different healthcare settings in Uganda. This study examined the relationship between EMR adoption and healthcare service delivery quality in two major facilities in the Entebbe region. A cross-sectional study design was employed with a sample of 212 healthcare workers and administrators from both hospitals. Data were collected using structured questionnaires and analyzed using SPSS version 25. Pearson correlation coefficients and multiple regression analysis were utilized to determine relationships between EMR utilization and service delivery indicators. Descriptive results revealed that the majority of healthcare workers frequently used the EMR system in their daily tasks, with high agreement that EMRs were easy to use, improved data accuracy, enabled faster retrieval of patient information, and enhanced the timeliness of service delivery. Mean scores ranged between 3.78 and 4.34, indicating strong positive perceptions of EMR effectiveness. Qualitative responses further confirmed that EMRs streamlined workflows, reduced manual errors, and supported quicker clinical decisions. Correlation analysis showed that EMRs had a strong and statistically significant positive relationship with healthcare service delivery (r = 0.781, p < 0.01). This indicated that increased adoption, effective utilization, and user confidence in EMRs were associated with improved service efficiency, reduced waiting times, and enhanced accuracy in patient management. The study concluded that EMRs played a critical role in improving the quality and performance of healthcare services. The technology significantly enhanced operational efficiency, reduced medical errors, and improved patient care quality. Healthcare facilities should invest in comprehensive staff training programs, robust technical infrastructure, and continuous system maintenance to maximize EMR benefits and overcome implementation challenges.
