Brief Summary:
This study tests the use of a decision aid for Veterans who are facing a decision about surgery for their Abdominal Aortic Aneurysm (AAA). The local site investigators (LSI) will enroll Veterans with AAA who are candidates for endovascular or open surgical repair. There are 22-24 VA Medical Centers participating in the trial. 12 sites will be randomly assigned to the intervention group, and 12 sites will be randomly assigned to the control group. Twelve Veterans will be enrolled at each site. At sites assigned to the intervention arm, Veterans will receive a decision aid with information about the two types of surgery for AAA repair, open and endovascular, and complete a survey about their preferences. Veterans at control sites will complete the same survey, but will not receive the decision aid. After their surgery, Veterans will take another survey asking about their satisfaction. The LSI will compare the results of the survey between Veterans' in the intervention and control groups to determine the effect of the decision aid on agreement between preference and repair type.

Detailed Description:
This is a cluster randomized trial comparing two ways to better align Veterans' preferences and treatments for AAA: (1) a validated decision aid describing AAA repair types with a survey measuring Veterans' preference for repair type -- versus (2) the survey alone. Enrolled Veterans will be candidates for either endovascular or open repair, and be followed at VA hospitals by vascular surgery teams who regularly perform both types of repair. In Aim 1, the investigators will determine Veterans' preferences for endovascular or open repair and identify domains associated with each repair type. In Aim 2, the investigators will compare agreement between Veterans' preferences and repair type between the decision aid+survey and survey-alone groups. In Aim 3, the investigators will investigate the facilitators and barriers of implementing a decision aid in a VA surgical clinic. The investigators will identify factors associated with agreement. The investigators' findings will be reported to the National Surgery Office Vascular Surgery Advisory Board to help ensure Veterans' preferences remain at the center of AAA treatment decisions. The investigators have recruited 20 VA Medical Centers and their vascular surgery teams to participate in this trial.

Arm Intervention/treatment
Experimental: decision aid
the experimental group will receive the decision aid
Other: Decision aid
Decision aid for repair type for aortic abdominal aneurysms

No Intervention: control
the control group will only receive the survey

Primary Outcome Measures :
  1. Veteran preference for repair type [ Time Frame: 30 days ]
    The investigators' survey will measure the effect of the decision aid on Veterans preference for repair type for abdominal aortic aneurysms and domains associated with preference for each repair type (endovascular or open)

  2. Agreement between Veterans preferences for repair type and actual repair type [ Time Frame: 30 days ]
    The investigators' survey instruments will assess the effect of the decision aid on the agreement between Veteran's preference for repair type and actual repair type they receive

Secondary Outcome Measures :
  1. Decision regret scale [ Time Frame: 30 days ]
    The investigators will use the patient satisfaction questionnaire short form 18 to assess patient satisfaction
