Introduction and hypothesis: The role of the general obstetrician/gynaecologist completing routine urogynaecology procedures is controversial, and some research has suggested that these patients should be referred to high-volume subspecialists. In response to recent public and regulatory scrutiny of vaginal mesh procedures, credentialling guidelines have been released in Australia requiring surgeons to demonstrate a minimum caseload prior to performing tension-free vaginal tape (TVT) surgery for incontinence. Hence, a retrospective cohort study was conducted to evaluate the long-term quality of life outcomes of TVT procedures for high- and low-volume surgeons.
Methods: One hundred seventy patients who had undergone TVT surgery between 1 May 2011 and 1 May 2016 in the Sunshine Coast health district were invited to complete the UDI-6 (Urinary Distress Inventory) and IIQ-7 (Incontinence Impact Questionnaire) surveys. Perioperative information was accessed from available health records. Mean UDI-6 and IIQ-7 scores were compared for high- and low-volume groups, and the groups were assessed for confounding factors.
Results: Of the 170 patients eligible, 83 completed the surveys (47.2%). No differences in UDI-6 or IIQ-7 scores were found between high- and low-volume surgeons (p > 0.05). High-volume surgeons completed more concomitant procedures amongst survey respondents (p < 0.05), though this was not reproduced when considering all 170 patients eligible for the study. There were no significant differences in age, ASA (American Society of Anaesthesiologists) score or complication rate amongst survey respondents.
Conclusions: Amongst the patients surveyed, high- and low-volume surgeons had similar long-term quality of life outcomes for TVT surgery, without any significant difference in complication rate.
