Reasons and Risk Factors for Failed Same-Day Discharge After Total Joint Arthroplasty

Efficacy and Safety of Catheter Interventions for Postoperative Urinary Retention After Primary Hip and Knee Total Joint Arthroplasty

INTRODUCTION

Postoperative urinary retention (POUR) is a common barrier to rapid-discharge hip and knee total joint arthroplasty (TJA). We evaluated the efficacy and safety of catheterization intervention methods for POUR before and after discharge.

METHODS

A total of 1,659 primary TJAs were retrospectively reviewed. POUR resolutions before and after discharge were evaluated relative to catheterization type and other covariates. Complications before and within 90 days of discharge were quantified. A total of 113 POUR cases comprised the analysis sample of 76 hips and 37 knees in 51 women and 62 men with an average age and body mass index of 68.6 (range 22 to 92) years and 31.7 (range 16 to 49) kg/m2.

RESULTS

POUR resolved before discharge for 82.3% (93/113) of patients, with equivalent resolution rates for intermittent catheterization alone (84.2%, 32/38) compared with indwelling catheterization with or without intermittent catheterization (82.6%, 57/69, P < 0.999), equivalent time to resolution (P = 0.319), and no difference in complication rates (P = 0.999). Complication rates within 90 days of discharge were higher for patients treated with indwelling catheters before discharge (P = 0.049). Resolution before discharge was more likely with increasing body mass index (P = 0.026) and less likely for patients with a history of urinary retention (P = 0.033). 60 percent (12/20) of patients with unresolved POUR were discharged with self-intermittent catheterization and 40% (8/20) with indwelling catheters, with no differences in efficacy and safety based on the catheterization type (P = 0.109).

DISCUSSION

Before discharge, we observed equivalent resolution rates and equivalent time to resolution for indwelling and intermittent catheterization alone without compromising patient safety. Intermittent catheterization is favored, however, because in situ catheter exposure is dramatically reduced and postdischarge complication rates are lower. Additional research is needed to develop evidence-based POUR guidelines for outpatient TJA.

Outpatient Total Joint Arthroplasty at a High-Volume Academic Center: An Analysis of Failure to Launch

BACKGROUND

Unanticipated failure to discharge home (failure to launch, FTL) following scheduled same-day discharge (SDD) total joint arthroplasty (TJA) is problematic for the surgical facility with respect to staffing, care coordination, and reimbursement concerns. The aim of this study was to review rates, etiologies, and contributing factors for FTL in SDD TJA at an inpatient academic medical center.

METHODS

All patients who underwent primary TJA between February 2021 and February 2023 were retrospectively reviewed. Of those scheduled for SDD, risk factors for FTL were compared with successful SDD. Readmission and emergency department (ED) visits were compared with historical cohorts. There were 3,093 consecutive primary joint arthroplasties performed, of which 2,411 (78%) were scheduled for SDD.

RESULTS

Overall, SDD was successful in 94.2% (n = 2,272) of patients who had an FTL rate of 5.8%. Specifically, SDD was successful in 91.4% with total hip arthroplasty, 96.0% with total knee arthroplasty, and 98.6% with unicompartmental knee arthroplasty. Factors that significantly increased the risk of FTL included general anesthesia versus spinal anesthesia (P < .0001), later surgery start time (P < .0001), longer surgical time (P = .0043), higher estimated blood loss (P < .0001), women (P = .0102), younger age (P = .0079), and lower preoperative mental health patient-reported outcomes scores (P = .0039). Readmission and ED visit rates were not higher in the SDD group when compared to historical controls (P = .6830).

CONCLUSIONS

With a comprehensive multidisciplinary approach dedicated to improving SDDs at an academic medical center, we have seen successful SDD in nearly 80% of primary TJA, with an FTL rate of 5.8%, and no increased risk of readmission or ED visits. Without adding many personnel, hospital recovery units, or other resources, simple interventions to help decrease FTL have included enhanced preoperative education and expectation settings, improved perioperative communications, reallocating personnel from the inpatient to the outpatient setting, the use of short-acting spinal anesthetics, and earlier scheduled surgery times.
