- 🩺 The system’s alerts led to actionable changes in prescriptions and documentation.
- 👁️ Ophthalmology had the highest acceptance rate at 96.59%, showcasing specialty variability.
- 📉 Acceptance rates for potentially inappropriate prescriptions stabilized at 51% despite increased prescription volumes.
- 🔍 Future improvements should focus on aligning alerts with specialty-specific workflows.
📚 Background
In outpatient care, potentially inappropriate prescribing can lead to adverse outcomes and inefficiencies in healthcare. Clinical decision support systems (CDSS) have emerged as promising tools to mitigate these issues. However, their effectiveness is often limited by incomplete medical records. This study aims to address these challenges by evaluating a CDSS that integrates diagnostic recommendations to ensure that prescribed medications are appropriately documented.
🗒️ Study
Conducted over one year in the outpatient departments of a regional teaching hospital, this prospective single-arm interventional study involved 44 physicians and analyzed 438,558 prescriptions. The CDSS, named MedGuard, utilized machine learning algorithms to provide diagnostic recommendations based on comprehensive data from the National Health Insurance Research Database.
📈 Results
The study revealed that MedGuard achieved an overall alert rate of 2.28% and a diagnostic recommendation acceptance rate of 56.55%. Notably, all accepted recommendations resulted in actionable changes, such as adjustments to prescriptions or the addition of missing diagnoses. The acceptance rates varied significantly across specialties, with ophthalmology leading at 96.59%, while rheumatology and surgery recorded acceptance rates of 0%.
🌍 Impact and Implications
The findings from this study highlight the potential of embedding diagnostic recommendations into alerts within a machine learning-based CDSS to enhance diagnostic completeness and promote safer outpatient care. By refining these alerts to better fit specialty-specific workflows, healthcare providers can improve patient outcomes and reduce the risks associated with inappropriate prescribing.
🔮 Conclusion
This study underscores the significant potential of machine learning in improving diagnostic recommendations within outpatient care. By integrating such technologies into clinical workflows, we can enhance medication appropriateness and ultimately support safer healthcare practices. Continued research and development in this area are essential for validating these findings across diverse clinical settings.

Evaluation of Diagnostic Recommendations Embedded in Medication Alerts: Prospective Single-Arm Interventional Study.
Abstract
BACKGROUND: Potentially inappropriate prescribing in outpatient care contributes to adverse outcomes and health care inefficiencies. Clinical decision support systems (CDSS) offer promising solutions, but their effectiveness is often constrained by incomplete medical records.
OBJECTIVE: This study aims to evaluate the effectiveness of a machine learning-based CDSS for enhancing diagnostic recommendations, which are system-suggested diagnoses, ensuring that each prescribed medication has a corresponding diagnosis documented and meets medication appropriateness.
METHODS: This prospective single-arm interventional study was conducted over 1 year in the outpatient departments of a hospital. The system provided diagnostic recommendations based on machine learning algorithms trained on data from the National Health Insurance Research Database. Outcome measures included alert rates, acceptance rates of diagnostic recommendations, and variability in system performance across specialties. Descriptive and trend analyses were used to evaluate the system’s effectiveness.
RESULTS: This study included 438,558 prescriptions from 44 physicians across 23 specialties, involving 125,000 unique patients in the outpatient departments of a regional teaching hospital. MedGuard, embedded with diagnostic recommendations, achieved an overall alert rate of 2.28% and a diagnostic recommendation acceptance rate of 56.55%. All accepted recommendations resulted in actionable changes, including prescription adjustments or the addition of missing diagnoses. Ophthalmology achieved the highest acceptance rate at 96.59%, while rheumatology, surgery, psychiatry, and infectious disease recorded acceptance rates of 0%, 0%, 24.74%, and 35%, respectively. Over the years, acceptance rates for potentially inappropriate prescriptions stabilized at 51%, despite increasing prescription volumes.
CONCLUSIONS: This study demonstrates the potential of embedding diagnostic recommendations into alerts within a machine learning-based clinical decision support system to improve diagnostic completeness and support safer outpatient care. Future efforts should refine alerts to align with specialty-specific workflows and validate their effectiveness in diverse clinical settings.
