Summary
Quality improvement training initially boosted deep vein thrombosis (DVT) prophylaxis but effects on DVT and dysphagia screening did not last. External programs may offer short-term gains in stroke care quality.
Area of Science:
- Healthcare Quality Improvement
- Stroke Care Management
- Clinical Interventions
Background:
- Quality indicator feedback is known to enhance stroke care.
- This study evaluated the impact of quality improvement (QI) training combined with feedback versus feedback alone on inpatient stroke indicators.
Purpose of the Study:
- To determine if QI training plus indicator feedback is more effective than feedback alone in improving deep vein thrombosis (DVT) prophylaxis and dysphagia screening in stroke patients.
- To assess the sustained impact of QI interventions on specific stroke care metrics.
Main Methods:
- A cluster-randomised trial involving hospitals comparing QI training plus feedback to feedback alone.
- Intervention sites received collaborative training, external facilitation, and feedback; control sites received only feedback.
- Mixed-effect logistic models analyzed DVT prophylaxis and dysphagia screening rates pre-, during, and post-intervention.
Main Results:
- QI training was associated with a significant early improvement in DVT prophylaxis (OR 4.90, p<0.001) but this effect diminished post-intervention.
- Dysphagia screening improved similarly in both groups during the active phase, with greater improvement in control sites post-intervention (OR 0.67, p=0.04).
- Logistic models indicated a positive association of the intervention with DVT performance during active implementation and a negative association with dysphagia performance post-implementation.
Conclusions:
- Quality improvement training demonstrated an initial benefit for DVT prophylaxis but lacked sustained effects.
- The impact of QI training varied by indicator, showing no lasting improvement for dysphagia screening.
- External QI programs may offer rapid but potentially transient improvements in healthcare performance.
