Factors Influencing Women's Decision to Participate or Not in a Surgical Randomised Controlled Trial for Surgical Treatment of Female Stress Urinary Incontinence

الملخص EN

The study aims to explore the potentially influential factors affecting women's decision to accept/decline participation in surgical randomised trial using a novel acceptance/refusal questionnaire (ARQ).

All women who were eligible to participate in SIMS-RCT were asked to complete the relevant section (acceptance/refusal) of the ARQ.

Women reported its degree of relevance for their decision on a six-point Likert scale (0 = highly irrelevant, 5 = highly relevant).

135 (98%) and 31 (70%) women completed the acceptance and refusal sections of the ARQ, respectively.

The most influencing factor in women’s acceptance was the anticipation of “potential personal benefit”; percentage of relevance (POR) was 91.9%, followed by interest in helping others by “supporting innovative medical research”; POR was 87.7%.

Most influencing factor in refusal for participation was “do not have time for follow-up”; POR was 56.8%, followed by “do not like the concept of randomisation”; POR was 54.4%.

In conclusion, this study identifies the most influential factors relevant to women decision-making whether or not to participate in RCTs assessing surgical interventions for female stress urinary incontinence (SUI).

A number of factors leading to refusal of participation are potentially correctable leading to better recruitment rates in future RCTs.
