To synthesise the perspectives of healthcare professionals and patients/residents of hospitals/nursing homes about determinants of inappropriate indwelling urinary catheter (IUC) use and strategies for reduction.

Qualitative evidence synthesis.

We searched MEDLINE, Scopus and CINAHL for studies published between 1 January 2000 and 23 May 2025.

Studies were eligible if they used qualitative methods to explore the perceptions and experiences of healthcare professionals and patients/residents of hospitals/nursing homes or their family members regarding the determinants of IUC use and reduction. Included studies focused on behavioural drivers or strategies to reduce inappropriate IUC use.

Two independent authors reviewed the search results, extracted and coded data, and assessed methodological strengths and limitations of studies. We used a thematic synthesis approach following the Cochrane–Campbell Handbook for Qualitative Evidence Synthesis and applied the Grading of Recommendations Assessment, Development and Evaluation–Confidence in the Evidence from Reviews of Qualitative Research approach to assess confidence in the findings.

We synthesised 24 studies. Perceived determinants of inappropriate IUC use included non-adherence to guidelines due to vague indications for initial IUC insertion, differing perspectives on benefits and risks, low priority given to the topic, limited accessibility or perceived unsuitability of alternatives, high nurse workload and staff shortages (moderate confidence). Ineffective nurse–physician communication, documentation difficulties and lack of training were also assumed to be linked to inappropriate IUC use (low confidence). Mentioned strategies for the reduction of inappropriate IUC use included additional training for healthcare professionals, clinician reminders to review or remove catheters, improved electronic documentation systems, increased staffing and greater use of IUC alternatives.

Key drivers of inappropriate IUC use are vague indications and routine decisions, lack of suitable and available alternatives, staff shortages and perceived lack of importance of the topic. Addressing these barriers is important for deimplementing inappropriate IUC use, and multifaceted strategies appear to be the most promising approach to address the multiple factors that drive current IUC misuse.
