Targeted identification of adverse events in coronary artery disease patients based on patient-reported outcomes.

Aim: Can focusing the adverse events search to patients with poor patient-reported outcome help in targeting adverse event detection? Patients & methods: Coronary artery revascularization patients of the Kuopio University Hospital from June 2012 to August 2014 categorized into those with clinically significant improvement (15D score change >= 0.015, n = 81) or deterioration (change >=-0.015, n = 64) in post-intervention health-related quality of life. Results: Major complications (27 vs 9%, p = 0.004) or postintervention infections (16 vs 5%, p = 0.031) were more common among those with deteriorated score. They also tended to have more cardiovascular (19 vs 9%, p = 0.071) and minor complications (16 vs 7%, p = 0.118). Conclusion: Patient-reported outcomes may potentially help in targeting the adverse events search so that a larger number of adverse events can be identified for efficient learning from them.
