Abstract 132: The POWR Survey: Patient and Physician Perspectives on Outcomes Weighting in Revascularization.
Objective: To better understand and compare how patients and physicians weight adverse outcomes of coronary revascularization.
Background: One in every twenty American adults is living with coronary heart disease. Given the high prevalence, approximately one million percutaneous coronary interventions (PCI) and half a million coronary artery bypass grafting (CABG) procedures are performed each year. The decision between PCI and CABG is based on studies that have looked at differences in major adverse cardiac events (MACE) in various populations. While the outcomes included in the MACE category are impactful, they are selected by physicians and do not include all possible adverse outcomes of coronary revascularization that affect patients. With so many Americans facing the clinical impact of coronary revascularization we wished to see if patients and physicians align in the weighting of twenty outcomes of coronary revascularization that have been identified.
Methods: 1500 physicians (500 internists, 500 cardiologists and 500 cardiac surgeons) and 54 patients were invited to fill out a survey over a 12 month period. Patients were approached upstream of diagnostic catheterization. Physicians were invited through an AMA database licensee. All responders were asked to use a rating scale to weight twenty outcomes of coronary revascularization.
Results: 54 patient and 57 physician (20 internists, 19 cardiologists and 18 cardiac surgeons) responses were received. Patients weighted stroke the highest (8.83/10), while physicians weighted death the highest (8.63/10). Patients and physicians differed (p<0.01) on myocardial infarction (physicians 6.59, patients 8.13), atrial fibrillation (physicians 4.28, patients 6.67), acute respiratory distress syndrome (ARDS) (physicians 5.94, patients 7.44), pseudoaneurysm (physicians 4.45, patients 6.23), post-operative chronic pain (physicians 5.20, patients 6.38) and procedural cost (physicians 4.22, patients 3.18). Notably patients weighted ARDS, renal failure, major bleeding, atrial fibrillation, mediastinits, post-operative chronic pain, post-procedural angina, pseudoaneurysm, long term plavix and pneumonia heavier than repeat PCI, another commonly used outcome for MACE.
Conclusions: Patients and physicians agree on which outcomes are most (death and stroke)and least impactful (incision scar), but there is a lot of variability in between supporting the reporting of more adverse outcomes and not just those included in MACE.
