Defining success following sling surgery: association of satisfaction with patient reported outcomes.
OBJECTIVE
The assessment of incontinence therapies is complicated by the variety of patient reported outcomes (PRO) measures used in research protocol. Patient satisfaction may be one of the most relevant albeit complex PRO measures and is a function of many related variables. We sought to assess the relationship between patient satisfaction and other PRO.


METHODS
A retrospective review of patients undergoing SPARC (n = 314) and autologous rectus pubovaginal sling (PVS) (n = 127) was performed, with 204 (SPARC) and 67 (PVS) patients completing questionnaire surveillance and minimum 12 month follow up. Outcomes were assessed using validated incontinence questionnaires (UDI-6, IIQ-7) supplemented with additional items addressing subjective improvement. Comparisons were made between patients reporting a willingness to recommend and repeat surgical intervention (combined variable, satisfaction surrogate) and achievement of defined endpoints in the remaining outcome measures.


RESULTS
A large difference in outcomes was seen depending on PRO measure analyzed. Dry was the strictest measure used (33%, SPARC; 39%, PVS; p = NS), while >or= 50% improvement was reported with the greatest frequency (75%, SPARC; 73%, PVS; p = NS). With the exception of pad use, a statistically significant association between all PRO measures and the willingness to recommend/repeat surgery was identified.


CONCLUSIONS
Our data demonstrate an association between a variety of PRO measures and patient reported satisfaction. Based on this finding, the development of a simplified and standardized PRO instrument, one that maintains an accurate reflection of patient satisfaction and is less cumbersome for the patient may be possible.
