Development of a decision aid for the treatment of benign prostatic hyperplasia: A four stage method using a Delphi consensus study.

Objective: To develop a web-based decision aid (DA) for the treatment of lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH).

Methods: From February-September 2014 we performed a four-stage development method: 1: Two-round Delphi consensus method among urologists, 2: Identifying patients' needs and expectations, 3: Development of DA content and structure, 4: Usability testing with LUTS/BPH patients.

Results: 1 (N=15): Dutch urologists reached consensus on 61% of the statements concerning users' criteria, decision options, structure, and medical content. 2 (N=24): Consensus was reached in 69% on statements concerning the need for improvement of information provision, the need for DA development and that the DA should clarify patients' preferences. 3: DA development based on results from stage 1 and stage 2. 4 (N=10): Pros of the DA were clear information provision, systematic design and easy to read and re-read.

Conclusion: A LUTS/BPH DA containing VCEs(**) was developed in cooperation with urologists and patients following a structured 4 stage method and was stated to be well accepted.

Practice Implications: This method can be adopted for the development of DAs to support other medical decision issues.
