The addition of peripheral nerve blocks to routine spinal or general anesthesia was associated with decreased risks of major adverse events after total hip or knee arthroplasty: A retrospective, propensity score-matched cohort study.

ABSTRACT:

Background

Although total joint arthroplasty is the most effective procedures for end-stage arthritis, the incidence of postoperative death and complications remains high. The association of additional peripheral nerve blocks (PNBs) to routine spinal or general anesthesia with major adverse events (including mortality and complication rates) in elective total hip arthroplasty (THA) or total knee arthroplasty (TKA) has been subject to inconclusive findings.

Methods

This retrospective observational single institution study included all patients ≧ 18 years undergoing their first elective THA or TKA from January 1, 2012 to December 31, 2021. A 1:2 propensity score matching (PSM) was performed to account for the baseline differences between two groups that were accepted to PNB or not. Kaplan-Meier curves were employed to estimate the effects of PNB on mortality. The associations of PNB and the complications were assessed by logistic regression models.

Results

We identified 1328 patients, among whom 197 had PNB and 1131 had not. The 90-day all-cause mortality was significantly reduced in patients with PNBs (0 % vs 2.79 %, P = 0.041) after THA or TKA, when compared to the non-PNB group. PNB was also associated with a lower risk of pulmonary complications (odds ratio [OR], 0.430; 95%confidence interval [CI],0.216-0.857) and deep vein thrombosis (OR, 0.103; 95%CI, 0.011-0.954).

Interpretation

The results of this observational, propensity score-matched cohort study suggested a strong association between the addition of PNBs to routine spinal or general anesthesia and decreased risks of major adverse events.

Project description:BackgroundInpatient rehabilitation is an expensive option following total hip arthroplasty (THA). We aimed to determine if THA patients who receive inpatient rehabilitation report better hip and quality of life scores post-surgery compared to those discharged directly home.MethodsProspective, propensity score matched cohort involving 12 private hospitals across five Australian States. Patients undergoing THA secondary to osteoarthritis were included. Those receiving inpatient rehabilitation for reasons other than choice or who experienced significant health events within 90-days post-surgery were excluded. Comparisons were made between those who did and did not receive inpatient rehabilitation for patient-reported hip pain and function (Oxford Hip Score, OHS) and 'today' health rating (EuroQol 0-100 scale). Rehabilitation provider charges were also estimated and compared.ResultsTwo hundred forty-six patients (123 pairs, mean age 67 (10) yr., 66% female) were matched on 19 covariates for their propensity to receive inpatient rehabilitation. No statistically nor clinically significant between-group differences were observed [OHS median difference (IQR): 0 (- 3, 3), P = 0.60; 0 (- 1 to 1), P = 0.91, at 90 and 365-days, respectively; EuroQol scale median difference 0 (- 10, 12), P = 0.24; 0 (- 10, 10), P = 0.49; 5 (- 10, 15), P = 0.09, at 35-, 90- and 365-days, respectively]. Median rehabilitation provider charges were 10-fold higher for those who received inpatient rehabilitation [median difference $7582 (5649, 10,249), P < 0.001]. Sensitivity analyses corroborated the results of the primary analyses.ConclusionUtilization of inpatient rehabilitation pathways following THA appears to be low value healthcare. Sustainability of inpatient rehabilitation models may be enhanced if inpatient rehabilitation is reserved for those most impaired or who have limited social supports.Trial registrationClinicalTrials.gov Identifier: NCT01899443 .

Project description:BackgroundTotal hip arthroplasty may be performed under general or spinal anesthesia. The purpose of the current study was to compare perioperative outcomes between anesthetic types for patients undergoing primary elective total hip arthroplasty.MethodsPatients who had undergone primary elective total hip arthroplasty from 2010 to 2012 were identified from the American College of Surgeons National Surgical Quality Improvement Program database. Operating room times, length of stay, thirty-day adverse events, and readmission were compared between patients who had received general anesthesia and those who had received spinal anesthesia. Propensity-adjusted multivariate analysis was used to control for selection bias and baseline patient characteristics.ResultsA total of 20,936 patients who had undergone total hip arthroplasty met inclusion criteria for this study. Of these, 12,752 patients (60.9%) had received general anesthesia and 8184 patients (39.1%) had received spinal anesthesia. On propensity-adjusted multivariate analyses, general anesthesia for total hip arthroplasty was associated with increased operative time (+12 minutes [95% confidence interval, +11 to +13 minutes]; p < 0.001) and postoperative room time (+5 minutes [95% confidence interval, +4 to +6 minutes]; p < 0.001). General anesthesia was also associated with the occurrence of any adverse event (odds ratio, 1.31 [95% confidence interval, 1.23 to 1.41]; p < 0.001), prolonged postoperative ventilator use (odds ratio, 5.81 [95% confidence interval, 1.35 to 25.06]; p = 0.018), unplanned intubation (odds ratio, 2.17 [95% confidence interval, 1.11 to 4.29]; p = 0.024), stroke (odds ratio, 2.51 [95% confidence interval, 1.02 to 6.20]; p = 0.046), cardiac arrest (odds ratio, 5.04 [95% confidence interval, 1.15 to 22.07]; p = 0.032), any minor adverse event (odds ratio, 1.35 [95% confidence interval, 1.25 to 1.45]; p = 0.001), and blood transfusion (odds ratio, 1.34 [95% confidence interval, 1.25 to 1.45]; p < 0.001). General anesthesia was not associated with any difference in preoperative room time, postoperative length of stay, or readmission.ConclusionsGeneral anesthesia was associated with an increased rate of adverse events and mildly increased operating room times.
