Costo-efectividad de las cintas de uretra media comparada con el tratamiento convencional de la incontinencia urinaria femenina de esfuerzo en Colombia

Objective: To estimate the cost-effectiveness of mid-urethral tapes compared with retropubic colposuspension and pubovaginal sling in patients with female stress urinary incontinence in Colombia. Methods: A decision tree model was developed to compare tension-free mid-urethral tapes with retropubic colposuspension and pubovaginal sling for the treatment of female stress urinary incontinence from a third-party payer perspective, including all direct costs. All monetary figures are expressed in Colombian pesos for 2019. The unit of outcome was clinical improvement defined as dry or continent patient. The effectiveness and safety data were extracted from a systematic literature search. We calculated the incremental cost-effectiveness ratio. Univariate sensitivity analyzes were performed. Results: Model results indicate that if the willingness to pay for a case of additional improvement is greater than $ 8 098 875 Colombian pesos (2417 USD), tension-free mid-urethral tapes represent the best alternative in terms of cost-effectiveness. These results were sensitive to the likelihood of clinical improvement of tension-free mid-urethral tapes. Conclusion: From the economic point of view, under the assumptions of the model and from a third-party payer perspective, mid-urethral tapes for the treatment of women with stress urinary incontinence, are cost-effective in Colombia. The results were sensitive to the costs and the effectiveness of surgical procedures.
