Factors influencing engagement in pelvic floor muscle exercise following radical prostatectomy: A scoping review

Abstract

Inconsistent engagement in pelvic floor muscle exercise (PFME) among patients with prostate cancer (PC) following radical prostatectomy may have contributed to varying effectiveness in improving urinary incontinence across studies. Identifying factors influencing engagement can help develop effective interventions to maximize participation, enhance urinary function and improve quality of life (QoL). This scoping review aims to systematically search for factors influencing PFME engagement among post radical prostatectomy patients managing urinary incontinence. Eligible publications in English were identified from various databases, including PubMed, CINAHL, ProQuest, PsycINFO and Scopus. A health science librarian was consulted to assist in formulating search terms, encompassing PC, PFME terms and influencing factors terms. We employed Colandrapp™ for data extraction, focusing on key themes such as study characteristics, PFME education and training, recommended sessions, engagement rates and factors influencing PFME engagement following radical prostatectomy. Results were presented in tables and supplemented by a narrative discussion addressing gaps in research knowledge. The synthesis drew from a diverse body of literature, blending quantitative and qualitative approaches, to contribute to a comprehensive understanding of PFME engagement factors. Twelve papers, based on 10 studies published between 2011 and 2018, met our inclusion criteria. The reviewed studies primarily employed longitudinal quantitative designs, except for one study that utilized a mixed-method design. Only three studies incorporated theories to guide the selection of potential factors influencing PFME engagement. The factors examined across the reviewed studies encompassed aspects related to the patient–partner relationship, patient's action control, planning (dyadic or individual), self-efficacy, perceived urinary incontinence and the patient–provider relationship. We observed conflicting findings regarding the factors influencing PFME engagement across studies. Our review underscores the importance of theory-informed studies using rigorous methodology and precise theoretical and operational definitions of potential factors. Such studies can help pinpoint the most influential factors to enhance PFME engagement and, ultimately, improve symptoms and QoL for PC patients. The scoping review also showed critical implications for nursing practice. Nurses should develop individualized and culturally sensitive interventions, integrate health behaviour change theories, assess patient–partner relationships and action control and consider intention's mediating role in the enhancement of PFME engagement following radical prostatectomy.
