1.  Attitudes, Awareness, and Barriers Regarding Evidence-Based Surgery Among Surgeons and Surgical Nurses 
World Journal of Surgery  2009;33(7):1348-1355.
Evidence-based surgery (EBS) is stressed to increase efficiency and health care quality, but not all surgeons and surgical nurses use EBS in clinical practice. To define future tailor-made interventions to improve evidence-based behavior, the aim of this study was to determine the attitude and awareness among surgeons and surgical nurses as to the paradigm of EBS and the barriers experienced when practicing EBS.
In this cross-sectional study, surgeons and surgical nurses at a university hospital in Amsterdam were invited to complete the BARRIERS scale and McColl et al. questionnaire. An evidence quiz was composed for the surgeons.
Response rates were 67% (29/43) for surgeons and 60% (73/122) for nurses. Attitudes toward EBS were positive. Among the surgeons, 90% were familiar with EBS terms, whereas only 40% of the nurses were. Common barriers for surgeons were conflicting results (79%, 23/29) and the methodologic inadequacy of research reports (73%, 21/29); and for nurses they were unawareness of EBS (67%, 49/73) and unclear reported research (59%, 43/73). Only about half of the convincing evidence presented in the quiz was actually applied.
Surgeons have a positive attitude toward EBS and are familiar with EBS terminology, but conflicting results and methodologic shortcomings of research reports are major barriers to practicing EBS. Continual confrontations with available evidence through frequent critical appraisal meetings or grand rounds and using more aggregate sources of evidence are advocated. Nurses can probably benefit from EBS training focusing on basic skills. Finally, collaboration is needed among surgeons and nurses with the same zest about EBS.

2.  Design and development of a decision aid to enhance shared decision making by patients with an asymptomatic abdominal aortic aneurysm 
To design, develop, and evaluate an evidence-based decision aid (DA) for patients with an asymptomatic abdominal aortic aneurysm (AAA) to inform them about the pros and cons of their treatment options (ie, surgery or watchful observation) and to help them make a shared decision.
A multidisciplinary team defined criteria for the desired DA as to design, medical content and functionality, particularly for elderly users. Development was according to the international standard (IPDAS). Fifteen patients with an AAA, who were either treated or not yet treated, evaluated the tool.
A DA was developed to offer information about the disease, the risks and benefits of surgical treatment and watchful observation, and the individual possibilities and threats based on the patient’s aneurysm diameter and risk profile. The DA was improved and judged favorably by physicians and patients.
This evidence-based DA for AAA patients, developed according to IPDAS criteria, is likely to be a simple, user-friendly tool to offer patients evidence-based information about the pros and cons of treatment options for AAA, to improve patients’ understanding of the disease and treatment options, and may support decision making based on individual values.
