Did Rapid Expansion of Same Day Discharge Hip and Knee Arthroplasty During the COVID-19 Pandemic Increase Early Complications?

Background: The COVID-19 pandemic has had a lasting impact on patients seeking total hip and knee arthroplasty (THA, TKA) including more patients undergoing same day discharge (SDD) following total joint arthroplasty (TJA). The purpose of this study was to assess whether expansion of SDD TJA during the COVID-19 pandemic resulted in more early complications following TJA. We anticipated that as many institutions quickly launched SDD TJA programs there may be an increase in 30-day complications. Methods: We retrospectively queried the ACS-NSQIP database for all patients undergoing primary elective TJA from January 1, 2018, to December 31, 2020. Participants who underwent THA or TKA between January 1, 2018 and March 1, 2020 were grouped into pre-COVID and between March 1, 2020 and December 31, 2020 were grouped into post-COVID categories. Patients with length of stay greater than 0 were excluded. Primary outcome was any complication at 30 days. Secondary outcomes included readmission and re-operation 30 days. Results: A total of 14,438 patients underwent TKA, with 9,580 occurring pre-COVID and 4,858 post-COVID. There was no difference in rates of total complication between the pre-COVID (3.55%) and post-COVID (3.99%) groups (p=0.197). Rates of readmissions for were similar for the pre-COVID (1.75%) and post-COVID (1.98%) groups (p=0.381). There was no statistically significant difference in respiratory complications between the pre-COVID (0.41%) and post-COVID group (0.23%, p=0.03). A total of 12,265 patients underwent THA, with 7,680 occurring pre-COVID and 4,585 post-COVID. There was no difference in rates of total complication between the pre-COVID (3.25%) and post-COVID (3.49%) groups (p=0.52). Rates of readmissions for were similar for the pre-COVID (1.77%) and post-COVID (1.68%) groups (p=0.381). There was no statistically significant difference in respiratory complications between the pre-COVID (0.16%) and post-COVID group (0.07%, p=0.26). Combined data to include THA and TKA patients did not find a statistical difference in the rate of complications or readmission but did note a decrease in the rate of combined respiratory complications in the post-COVID group (0.15% vs. 0.30%, p=0.028). Conclusion: Rapid expansion of SDD TJA during the COVID-19 pandemic did not increase overall complication, readmission, or re-operation rates. Level of Evidence: IV.

Routine Indwelling Urinary Catheterization Is Not Necessary During Total Hip Arthroplasty Performed Under Spinal Anesthesia.

Background: Perioperative indwelling urinary catheterization remains common in patients undergoing total hip arthroplasty. This study sought to examine the effect of routine catheterization following total hip arthroplasty performed under spinal anesthesia on urinary complications. Methods: A total of 991 consecutive patients who underwent primary total hip arthroplasty under spinal anesthesia over a 4-year period were retrospectively reviewed. Major postoperative urinary retention (POUR) was defined as persistent retention following 2 straight catheterizations, which required postoperative indwelling catheter placement. Minor POUR was defined as retention that resolved following 1 or 2 straight catheterizations. Statistical analyses were used to compare outcomes between those who received a routine indwelling catheter and those who did not. Results: Of the 991 patients included, 498 (50.3%) underwent routine indwelling urinary catheter placement preoperatively. Routine indwelling catheterization was associated with a higher rate of urinary tract infection (1.4% vs 0.0%, P = .015), but a lower rate of minor POUR (5.0% vs 10.3%, P = .001). There was no difference with respect to the rate of major POUR or discharge with an indwelling catheter. Multivariate analyses demonstrated indwelling catheterization to be independently associated with a lower rate of minor POUR (P = .021), but there was no association with overall POUR, major POUR, or discharge with a urinary catheter. Conclusion: These data suggest that routine indwelling urinary catheterization is likely unnecessary for patients undergoing total hip arthroplasty in the setting of spinal anesthetic and may even lead to increased risk of complications such as urinary tract infection.

Renal Cell Carcinoma as an Incidental Finding in Firefighters: A Case Series.

The link between cancer, including cancers of the kidney, and occupational exposure in firefighters has been well established. Renal cell carcinoma has a tendency to present incidentally on imaging rather than with the classic symptoms of flank pain and hematuria. In this case series, we identify four firefighter patients, all of whom initially presented with a kidney tumor as an incidental finding. We examine the absence of other risk factors in these patients along with current screening guidelines. This report aims to detail how these tumors present incidentally as well as evaluate the current screening guidelines in an effort to build awareness within this population. Patient demographics, risk factors, length of firefighting career, final pathology, and postoperative recurrence were evaluated. Four males underwent successful partial or total nephrectomy. All who have had follow-up have been tumor free with renal function intact. None are dialysis dependent. The role of routine renal imaging of this population is explored.
