Anticipating Urinary Retention Following Total Hip and Total Knee Replacements

Risk factors of postoperative urinary retention following total hip and knee arthroplasty

Aims

The aim of this meta-analysis was to determine the pooled incidence of postoperative urinary retention (POUR) following total hip and knee arthroplasty (total joint replacement (TJR)) and to evaluate the risk factors and complications associated with POUR.

Methods

Two authors conducted searches in PubMed, Embase, Web of Science, and Scopus on TJR and urinary retention. Eligible studies that reported the rate of POUR and associated risk factors for patients undergoing TJR were included in the analysis. Patient demographic details, medical comorbidities, and postoperative outcomes and complications were separately analyzed. The effect estimates for continuous and categorical data were reported as standardized mean differences (SMDs) and odds ratios (ORs) with 95% CIs, respectively.

Results

A total of 31 studies were included in the systematic review. Of these, 29 studies entered our meta-analysis, which included 3,273 patients diagnosed with POUR and 11,583 patients without POUR following TJR. The pooled incidence of POUR was 28.06%. Demographic risk factors included male sex (OR 1.81, 95% CI 1.26 to 2.59), increasing age (SMD 0.16, 95% CI 0.04 to 0.27), and American Society of Anesthesiologists grade 3 to 4 (OR 1.39, 95% CI 1.10 to 1.77). Patients with a history of benign prostatic hyperplasia (OR 1.99, 95% CI 1.41 to 2.83) and retention (OR 3.10, 95% CI 1.58 to 6.06) were more likely to develop POUR. Surgery-related risk factors included spinal anaesthesia (OR 1.44, 95% CI 1.19 to 1.74) and postoperative epidural analgesia (OR 2.82, 95% CI 1.65 to 4.82). Total hip arthroplasty was associated with higher odds of POUR compared to total knee arthroplasty (OR 1.10, 95% CI 1.02 to 1.20). Postoperatively, POUR was associated with a longer length of stay (SMD 0.21, 95% CI 0.02 to 0.39).

Conclusion

Our meta-analysis demonstrated key risk variables for POUR following TJR, which may assist in identifying at-risk patients and direct patient-centered pathways to minimize this postoperative complication.

Onset PrevenTIon of urinary retention in Orthopaedic Nursing and rehabilitation, OPTION-a study protocol for a randomised trial by a multi-professional facilitator team and their first-line managers' implementation strategy

BACKGROUND

The Onset PrevenTIon of urinary retention in Orthopaedic Nursing and rehabilitation, OPTION, project aims to progress knowledge translation vis-à-vis evidence-based bladder monitoring in orthopaedic care, to decrease the risk of urinary retention, and voiding complications. Urinary retention is common whilst in hospital for hip surgery. If not properly identified and managed, there is a high risk of complications, some lifelong and life threatening. Although evidence-based guidelines are available, the implementation is lagging.

METHODS

Twenty orthopaedic sites are cluster randomised into intervention and control sites, respectively. The intervention sites assemble local facilitator teams among nursing and rehabilitation staff, including first-line managers. The teams receive a 12-month support programme, including face-to-face events and on-demand components to map and bridge barriers to guideline implementation, addressing leadership behaviours and de-implementation of unproductive routines. All sites have access to the guidelines via a public healthcare resource, but the control sites have no implementation support. Baseline data collection includes structured assessments of urinary retention procedures via patient records, comprising incidence and severity of voiding issues and complications, plus interviews with managers and staff, and surveys to all hip surgery patients with interviews across all sites. Further assessments of context include the Alberta Context Tool used with staff, the 4Ps tool for preference-based patient participation used with patients, and data on economic aspects of urinary bladder care. During the implementation intervention, all events are recorded, and the facilitators keep diaries. Post intervention, the equivalent data collections will be repeated twice, and further data will include experiences of the intervention and guideline implementation. Data will be analysed with statistical analyses, including comparisons before and after, and between intervention and control sites. The qualitative data are subjected to content analysis, and mixed methods are applied to inform both clinical outcomes and the process evaluation, corresponding to a hybrid design addressing effectiveness, experiences, and outcomes.

DISCUSSION

The OPTION trial has a potential to account for barriers and enablers for guideline implementation in the orthopaedic context in general and hip surgery care in particular. Further, it may progress the understanding of implementation leadership by dyads of facilitators and first-line managers.

TRIAL REGISTRATION

The study was registered as NCT04700969 with the U.S. National Institutes of Health Clinical Trials Registry on 8 January 2021, that is, prior to the baseline data collection.
