Introduction: The PReferences for Open Versus Endovascular Repair of Abdominal Aortic Aneurysm (PROVE-AAA) trial aimed to determine the efficacy of a validated decision aid to enable better alignment between patient preference and their ultimate repair. We sought to determine the key factors influencing the decision-making of veterans for endovascular repair of abdominal aortic aneurysm (EVAR) or open surgical repair (OSR).
Methods: A total of 235 veterans in the PROVE-AAA trial were asked their information sources regarding repairs, employment status, and preferred intervention. Answers were coded and analyzed using conventional content analysis to generate nonoverlapping themes, then stratified by employment status.
Results: Forty-two patients (17.8% of enrollees) provided their source of information for OSR prior to using a decision aid. 81% of retired veterans were greater than 70 y old, while 58% of nonretired veterans were greater than 70 (P = 0.003). The most common information source was from a vascular surgeon/professional or unspecified MD/other health professionals (51.4%), while sources from outside this group made up the remaining 48.5%. The most preferred procedure was EVAR. However, nonretired individuals were more likely to prefer OSR. These data on information source and preferred procedure were similar in patients who provided their source for EVAR.
Conclusions: Veterans in the PROVE-AAA study were more likely to be retired and more likely to rely on information from an unspecified MD/other health professionals for EVAR. Although both retired and nonretired veterans preferred EVAR the most, nonretired veterans were more likely to prefer OSR despite being younger.
