Abstract

Background

Compared to general anesthesia (GA), neuraxial anesthesia (NA) has been associated with improved outcomes after total joint arthroplasty (TJA). We examined the impact of NA on patient outcomes in an institution with an established rapid recovery protocol.

Methods

This is a single-institution retrospective analysis of 5914 consecutive primary TJA performed from July 2015 to June 2018. Univariate tests and multivariate regression compared length of stay (LOS), transfusion rates, hematocrit levels, discharge disposition, and emergency room returns between patients receiving GA and NA.

Results

Patients receiving NA had a significantly shorter LOS (total hip arthroplasty [THA]: GA 1.74 vs NA 1.36 days, P < .001; total knee arthroplasty [TKA]: GA 1.77 vs NA 1.64 days, P < .001). Both THA and TKA patients receiving NA were less likely to require transfusion (THA: GA 5.8% vs NA 1.6%, P < .001; TKA: GA 2.5% vs NA 0.5%, P < .001) and had a higher postoperative hematocrit (THA: GA 32.50% vs NA 33.22%, P < .001; TKA GA 33.57 vs NA 34.50%, P < .001). Patients receiving NA were more likely to discharge home (THA: GA 83.4% vs NA 92.3%, P < .001; TKA: GA 83.3% vs NA 86.3%, P = .010) (THA: NA adjusted OR [aOR] 2.04, P < .001; TKA: NA aOR 1.23, P = .048) and had significantly lower rates of 90-day emergency room visits (THA: NA aOR 0.61, P = .005; TKA: NA aOR 0.74, P = .034).

Conclusion

NA appears to contribute to decreased LOS, short-term complications, and transfusions while facilitating home discharge following TKA and THA. These trends are consistent when controlling for patient-specific risk factors, suggesting NA may enhance outcomes for patients with increased age, body mass index, and comorbidities.

Level Of Evidence

Level III Retrospective Cohort Study.

Materials and Methods

Institutional review board approval was obtained. A retrospective chart review was performed for a consecutive series of primary unilateral TJA performed between July 2015 and June 2018. Surgeries were performed by 1 of 13 board-certified orthopedic surgeons at a single institution. All surgeries were conducted post-implementation of a standardized institutional rapid recovery protocol which remained constant over the study period. Data were collected via an administrative database for patient

Results

In total, 2896 patients (49.0%) received GA and 3018 (51.0%) received NA. Over the study time period, the proportion of patients receiving NA increased from 43.3% in 2015 to 56.2% in 2018. When examining TKA and THA patients separately (Table 1), patients receiving NA had a lower BMI (THA: GA 30.43 vs NA 29.13 kg/m2, P < .001; TKA: GA 33.14 vs NA 31.44, kg/m2, P < .001) and a lower percentage of ASA 3 or 4 (THA: GA 47.0% vs NA 30.6%, P < .001; TKA: GA 50.2% vs NA 38.7%, P < .001). TKA patients

Discussion

THA and TKA are typically successful and most patients report improved pain, quality of life, and physical and mental health following recovery from these procedures [[17], [18], [19]]. In part because of this success, the number of these surgeries performed annually continues to increase, necessitating that the healthcare system builds on prior improvements in quality of care and cost containment efforts associated with surgical intervention. Decreasing LOS, increasing home discharge, and

Conclusion

NA appears to contribute to decreased LOS, decreased short-term complications, and decreased transfusions while facilitating home discharge in patients undergoing TKA and THA. These trends are consistent when controlling for patient-specific risk factors, suggesting NA may enhance outcomes for patients with increased age, BMI, and comorbid conditions undergoing TJA. Increased utilization of NA may improve patient outcomes and decrease costs associated with these procedures and should be

    The difference in the magnitude of the effect sizes observed between our study and the study by Warren et al. may be related to the longer 90-day follow-up period assessed in the present study. While the current study did not assess postoperative medical and surgical complications, several contemporary studies assessing differences in complication rates between TKA patients receiving spinal and general anesthesia have found favorable results among patients receiving spinal anesthesia [12,21,29,30]. Pugely et al. assessed 14,052 primary TKA patients of which 6,030 (42.9%) underwent spinal anesthesia and 8,022 (57.1%) received general anesthesia [12].

    This initiative restructured the hospital reimbursement model for TJAs and placed a greater emphasis on value-based care. Hospital systems and orthopedic institutions responded to this change by implementing clinical care pathways geared toward reducing hospital length of stay (LOS) and overall cost of care [4–9]. These pathways have proved successful while maintaining patients' safety as well as clinical and patient-reported outcomes.
