Insights
An electronic prescribing system improved pediatric prescribing for common conditions. This evidence-based tool enhanced provider practices, showing significant improvements in prescription accuracy for various pediatric illnesses.
Area of Science:
- Pediatric Healthcare Informatics
- Clinical Decision Support Systems
- Evidence-Based Medicine Implementation
Background:
- Previous studies demonstrated that electronic prescription systems improve pediatric prescribing for otitis media.
- The need to assess the broader applicability of such systems for other common pediatric conditions remains.
- Optimizing prescribing practices in pediatric outpatient settings is crucial for patient outcomes and healthcare efficiency.
Purpose of the Study:
- To evaluate the effectiveness of a point-of-care, evidence-based electronic prescription writer and decision support system.
- To determine if this system improves prescribing behavior for a range of common pediatric conditions beyond otitis media.
- To assess the impact on the proportion of prescriptions dispensed in accordance with evidence-based guidelines.
Main Methods:
- A cluster randomized controlled trial was conducted across a teaching clinic/practice site and a primary care pediatric clinic.
- The intervention involved an evidence-based message system delivering real-time prescribing feedback for acute otitis media, allergic rhinitis, sinusitis, constipation, pharyngitis, croup, urticaria, and bronchiolitis.
- Prescribing practices were assessed by measuring the proportion of prescriptions dispensed in accordance with evidence.
Main Results:
- The intervention group showed a 4-percentage-point improvement in evidence-based prescribing (38% to 42%).
- The control group improved by 1 percentage point (39% to 40%), with an adjusted difference favoring the intervention group by 8%.
- The effectiveness of the intervention remained consistent over time.
Conclusions:
- A point-of-care evidence-based prescription writer and decision support system significantly improved prescribing practices for common pediatric outpatient conditions.
- The findings support the integration of such systems into routine pediatric care to enhance evidence-based prescribing.
- This approach demonstrates a scalable method for improving the quality of care in pediatric practice.
Objectives:
Having shown previously that an electronic prescription writer and decision support system improved pediatric prescribing behavior for otitis media in an academic clinic setting, we assessed whether point-of-care delivery of evidence could demonstrate similar effects for a wide range of other common pediatric conditions.
Design:
Cluster randomized controlled trial.
Setting:
A teaching clinic/clinical practice site and a primary care pediatric clinic serving a rural and semi-urban patient mix.
Participants:
A total of 36 providers at the teaching clinic/practice site and eight providers at the private primary pediatric clinic.
Intervention:
An evidence-based message system that presented real-time evidence to providers based on prescribing practices for acute otitis media, allergic rhinitis, sinusitis, constipation, pharyngitis, croup, urticaria, and bronchiolitis.
Outcome Measures:
The proportion of prescriptions dispensed in accordance with evidence.
Results:
The proportion of prescriptions dispensed in accordance with evidence improved four percentage points, from 38% at baseline to 42% following the intervention. The control group improved by one percentage point, from 39% at baseline to 40% at trial's conclusion. The adjusted difference between the intervention and control groups was 8% (95% confidence interval 1%, 15%). Intervention effectiveness did not decrease with time.
Conclusion:
For common pediatric outpatient conditions, a point-of-care evidence-based prescription writer and decision support system was associated with significant improvements in prescribing practices.
