Patient-reported outcome measures for pain in women with pelvic floor disorders: a systematic review

Comparing Patient-Reported Outcome Measures for Pain in Women With Pelvic Floor Disorders: A Scoping Review

Women with pelvic floor disorders (PFDs) typically undergo surgery involving transvaginal mesh implants; however, transvaginal mesh surgery is associated with many adverse events including post-surgical pain. Assessment of pain as a symptom is necessary using patient-reported outcome measures (PROMs). This scoping review aimed to describe and compare existing PROMs previously used to measure pain in women with PFDs. A scoping search of Ovid MEDLINE, EMBASE, CINAHL Plus, Ovid PsycInfo, and grey literature was conducted. Studies published in English describing the development, implementation, and application of PFD-associated pain PROMs among adult women before and after pelvic floor surgery were included. From each article, a descriptive summary organised by study first author, publication year, country, setting, aim, study characteristics, and results were extracted. From 2,604 articles identified, 54 studies were included, describing 44 PROMs. Most studies described at least 2 to 3 instruments. The Pelvic Floor Distress Inventory-20 was most commonly described by 12 studies followed by the Patient Global Impression of Improvement scale. Of the 44 PROMs, 27 were condition-specific, of which 9 included items on pain; 17 generic PROMs, 4 of which contained items on pain; and 6 pain-specific PROMs. PROMs identified in our review measured pain not related to PFDs or pelvic floor surgery and quantified the pain experienced. These PROMs did not measure all areas of pain including region, sensation, impact, and triggers. The findings of this review will assist with developing a new pain-specific PROM in this population. PERSPECTIVE: Women with pelvic floor disorders often undergo surgery involving transvaginal mesh, from which they experience debilitating pain. Pain is a major issue impacting women's lives. Patient-reported outcome measures can be used to assess the pain; however, it is unclear whether existing instruments are relevant.

Development of a conceptual framework for a new patient-reported outcome measure for pain in women following mesh surgery for pelvic floor disorders: a qualitative study

Introduction and hypothesis

The Australasian Pelvic Floor Procedure Registry (APFPR) collects both clinical and health-related quality of life (HRQoL) data on women undergoing surgery using a prosthesis such as mesh for pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The registry lacks a suitable instrument to assess pain in women following mesh surgery for SUI and POP. This qualitative study describes the views on pain following mesh surgery in women and clinicians through the development of a conceptual framework, which may inform the development of a new instrument for the APFPR.

Methods

We conducted semi-structured interviews with women following mesh surgery for POP and SUI (n=17) and clinicians (n=6) in Victoria, Australia. We sought to reveal aspects of any sort of pain after a pelvic floor procedure. Interviews covered sensation, region, continuity of pain, triggers, and the mode and method of administration for a new pain-specific patient-reported outcome measure. Data were analysed using thematic analysis.

Results

We identified the important components of pain felt by women with POP and SUI after surgery using mesh. From the seven themes outlined, a conceptual framework was developed compiling related components of pain into six specific domains.

Conclusions

This study identifies the important components of pain felt by women following mesh surgery. It is hoped that the development of a pain-specific PROM, as supported by clinicians, will assist in the timely and appropriate diagnosis and management of POP and SUI.
