Enhancing Outpatient Care Efficiency through Digital Prescription Decision-Support Systems

Outpatient care is increasingly challenged by rising pharmaceutical costs, prescribing errors, and medication non-adherence. Digital Clinical Decision-Support Systems (CDSS) integrated into electronic health records (EHRs) have emerged as powerful tools for optimizing prescribing practices. This paper examines the impact of CDSS on outpatient prescription management, with emphasis on drug safety, substitution optimization, and adherence monitoring. Through a mixed-methods analysis of prescription data and clinician interviews, the study evaluates the effectiveness of CDSS in reducing inappropriate prescribing, improving adherence, and lowering costs. Results suggest that CDSS can reduce prescribing errors by 18%, increase generic substitution uptake by 15%, and improve adherence by 12%. These findings indicate that smart digital platforms, when integrated with substitution frameworks, can significantly enhance the sustainability, safety, and equity of outpatient prescription systems.
