Summary
Randomized controlled trials are the most valued evidence by physicians for clinical decision support. This evidence type significantly outperforms local recommendations and no evidence, guiding better healthcare information design.
Area of Science:
- Medical Informatics
- Evidence-Based Medicine
Background:
- Clinical decision support systems increasingly integrate medical literature.
- Identifying impactful evidence types is crucial for enhancing these systems.
Purpose of the Study:
- To determine which types of medical evidence physicians perceive as most valuable for clinical decision support.
Main Methods:
- A survey was distributed to US family practice physicians and internists.
- Physicians rated the value of various evidence types (RCTs, local recommendations, expert opinion, etc.) on a Likert scale.
- Statistical analysis included ANOVA and pairwise comparisons.
Main Results:
- Randomized controlled trials (RCTs) received the highest ratings (mean 5.07).
- RCTs were significantly preferred over locally developed recommendations and no evidence (P < .05).
- A significant interaction was found between evidence type and clinical area (P = .0001).
Conclusions:
- Presenting data with pertinent controlled evidence from the literature is superior to uninterpreted data or local recommendations.
- Understanding physician perceptions is key to designing effective computer-generated clinical messages.
- Evidence-based approaches enhance clinical decision support more effectively.
