RESUMEN
OBJECTIVE: This study explores the opportunities of social media advertisements as a recruitment strategy in women with stress urinary incontinence (SUI). STUDY DESIGN: This feasibility study was part of a larger clinical trial on the effects of a patient decision aid for SUI treatment. We started a 61-day social media advertisement campaign to recruit women for the trial. The primary outcome of our study was enrolment pace. Secondary outcomes involved cost per participant, baseline demographic comparison and ad campaign performance metrics. Additionally, we interviewed recruited participants to identify the facilitators and barriers of our approach. RESULTS: Ten participants were recruited, of whom 8 completed the full study protocol (2 questionnaires 6 months apart). The enrolment pace, 4.0 study participants per month, was faster compared to the average of 2.7 participants per month through conventional methods. The campaign reached 87 clicks on the advertisement per day and 1 % of these women showed interest in our study by contacting us. The overall conversion rate from click to full participation was 0.2 %. The costs per participant were 112. Besides higher age, the demographics of the social media recruited participants were comparable to the conventional inclusions. Qualitative analysis identified more user-oriented enrolment procedures and potential participant benefit as facilitators of social media recruitment. CONCLUSION: This study shows that social media recruitment can be feasible in trials for women with SUI. It can accelerate recruitment of eligible participants. Optimising the enrolment procedure to better meet participants' needs and recruitment benefits may improve participation and cost-effectiveness. Trial registration ID 2017-3540.
RESUMEN
The clinical assessment of pelvic organ prolapse (POP) and associated treatment strategies is currently limited to anatomical and subjective outcome measures, which have limited reproducibility and do not include functional properties of vaginal tissue. The objective of our study was to evaluate the feasibility of using cutometry and indentometry for non-invasive biomechanical assessment of the vaginal wall in women with POP. Both techniques were applied on the vaginal wall of 20 women indicated for surgical correction of POP stage two or higher. The primary outcome was the measurement success rate. Measurements were considered successful if biomechanical parameters were generated after a maximum of three attempts. Secondary outcomes included acquisition time, number of attempts to obtain a successful measurement, and biomechanical parameters. Measurements were successfully performed on the anterior vaginal wall of 12 women with cystocele and the posterior vaginal wall of eight women with rectocele. The success rate was 100% for both techniques and acquisition time was under 1 minute for all 20 measurements. Tissue fast elasticity of the posterior vaginal wall (rectocele) was significantly higher than that of the anterior vaginal wall (cystocele) and negatively correlated with age (r = - 0.57, P < 0.05). In women with POP, measuring the biomechanical properties of the vaginal wall using cutometry and indentometry is technically feasible. Objective evaluation of biomechanical properties may help to understand the pathophysiology behind surgical outcomes, providing an opportunity for the identification of patients at risk for (recurrent) prolapse, and individualized treatment decisions.
