Development and usability testing of a multi-criteria value clarification methods for patients with localized prostate cancer.

Current guidelines for the development of decision aids recommend that they have to include a process for helping patients clarify their personal values, for example, by using values clarification methods. In this article, we extensively described the development process of the web-based values clarification method for patients with localized low- to intermediate-risk prostate cancer based on the analytic hierarchy process. With analytic hierarchy process, the relative importance of different attributes of available treatments can be determined through series of pairwise comparisons of potential outcomes. Furthermore, analytic hierarchy process is able to use this information to present respondents with a quantitative overall treatment score and can therefore give actual treatment advice upon patients' request. The addition of this values clarification method to an existing web-based treatment decision aid for patients with localized prostate cancer is thought to improve the support offered to patients in their decision-making process and their decision quality.

Uptake and usage of an online prostate cancer treatment decision aid in Dutch clinical practice: A quantitative analysis from the Prostate Cancer Patient Centered Care trial.

Implementation of patient's decision aids in routine clinical care is generally low. This study evaluated uptake and usage of a novel Dutch web-based prostate cancer treatment decision aid within the Prostate Cancer Patient Centered Care trial. From an estimated total patient sample of 1006 patients, 351 received a decision aid (35% implementation rate; hospital ranges 16%-84%). After receipt of the decision aid, most patients accessed the decision aid, utilized most functions, although not completely, and discussed the decision aid summary in a subsequent consultation with their care provider. Including nurses for dissemination of decision aids seemed to positively affect decision aid uptake. Once received, patients seemed able to use the decision aid and engage in shared decision-making as intended; however, decision aid uptake and complete usage of all decision aid components should be further improved. Prior to the diagnosis consultation, handing out of the decision aid should be prepared.

A global, incremental development method for a web-based prostate cancer treatment decision aid and usability testing in a Dutch clinical setting.

Many new decision aids are developed while aspects of existing decision aids could also be useful, leading to a sub-optimal use of resources. To support treatment decision-making in prostate cancer patients, a pre-existing evidence-based Canadian decision aid was adjusted to Dutch clinical setting. After analyses of the original decision aid and routines in Dutch prostate cancer care, adjustments to the decision aid structure and content were made. Subsequent usability testing (N = 11) resulted in 212 comments. Care providers mainly provided feedback on medical content, and patients commented most on usability and summary layout. All participants reported that the decision aid was comprehensible and well-structured and would recommend decision aid use. After usability testing, final adjustments to the decision aid were made. The presented methods could be useful for cultural adaptation of pre-existing tools into other languages and settings, ensuring optimal usage of previous scientific and practical efforts and allowing for a global, incremental decision aid development process.
