Hip Fracture Repair by the Post-Call Surgeon: A Multicenter Retrospective Review.

INTRODUCTION: The purpose of this study was to evaluate surgeons' ability to perform or supervise a standard operation with agreed-upon radiologic parameters after being on call. METHODS: We reviewed a consecutive series of patients with intertrochanteric hip fractures treated with a fixed angle device at 9 centers and compared corrected tip-apex distance and reduction quality for post-call surgeons versus those who were not. Subgroup analyses included surgeons who operated the night before versus not and attending-only versus resident involved cases. Secondary outcomes included union and perioperative complications. RESULTS: One thousand seven hundred fourteen patients were of average age 77 years. Post-call surgeons treated 823 patients and control surgeons treated 891. Surgical corrected tip-apex distance did not differ between groups: on-call 18 mm versus control 18 mm (P = 0.59). The Garden indices were 160° on the AP and 179° on the lateral in both groups. In 66 cases performed by surgeons who operated the night before, the TAD was 17 mm. No difference was noted in corrected tip-apex distance with and without resident involvement (P = 0.101). No difference was observed in pooled fracture-related complications (P = 0.23). CONCLUSION: Post-call surgeons demonstrated no difference in quality and no increase in complications when performing hip fracture repair the next day compared with surgeons who were not on call.

Reducing Narcotic Usage With 0.5% Bupivacaine Periarticular Injections in Total Knee Arthroplasty.

BACKGROUND: Periarticular injections (PAIs) and adductor canal blocks (ACBs) are widely accepted pain management strategies for total knee arthroplasty (TKA); however, the optimal anesthetic concentration to provide adequate pain relief while avoiding toxicity remains controversial. The purpose of this study is to evaluate the efficacy of different anesthetic concentrations for PAI alone and in combination with ACB. METHODS: This retrospective cohort study of patients undergoing primary TKAs between January 2019 and November 2020 included 3 groups: 0.25% PAI (50 cc of 0.25% bupivacaine PAI diluted with 50 cc of saline and ketorolac), 0.5% PAI (50 cc of 0.5% bupivacaine with 50 cc of saline and ketorolac), and PAI + ACB (ultrasound-guided preoperative anesthesiologist-administered ACB and 0.25% PAI). RESULTS: In total, 368 TKAs were analyzed (123 0.25%, 132 0.5%, and 113 PAI + ACB). Total overall hospital narcotic usage in oral morphine equivalents (OME) was significantly lower for the 0.5% group (120.09 vs 165.26 and 175.75) compared to the 0.25% and PAI + ACB groups, respectively (P < .0001). Cumulative OME for the first 3 shifts was also lower for 0.5% (68.7 vs 83.7 and 76.4) compared to the 0.25% and PAI + ACB groups, respectively (P = .030). Total postoperative narcotics in OME were significantly lower for 0.5% (617.9 vs 825.2 and 1047.6) than 0.25% and PAI + ACB, respectively (P = .0003). Number of prescriptions within 6 weeks postoperatively were also significantly lower for 0.5% (1.7) than 0.25% (2.1) and PAI + ACB (2.4) (P = .0003). CONCLUSION: Patients receiving 0.5% PAI had lower narcotic usage compared to 0.25% PAI or PAI + ACB. ACB may be eliminated without compromising pain control if the dose of local anesthetic in the PAI is sufficiently high.

Combined treatment of intraoperative cell-salvage and tranexamic acid for primary unilateral total hip arthroplasty: Are there added benefits?

BACKGROUND: Blood management strategies in total hip arthroplasty (THA) are essential in reducing intraoperative blood loss, blood transfusion and associated complications. This study investigates whether using intraoperative cell-salvage (ICS) with tranexamic acid (TXA) has additional effects on blood loss and allogeneic transfusion in primary THA. Additionally, we evaluated the financial impact of using ICS on our institution. METHODS: Using an institutional database, 1171 cases of primary unilateral THA performed between May 2015 and January 2016 were identified. Subjects were separated into those who received only TXA (n = 323) and those who received TXA and ICS (n = 848). Calculated blood loss and post-operative blood transfusions were assessed using logistic regression. Drop in hematocrit was assessed using linear regression. Multivariable models adjusted for intraoperative blood transfusions, pre-operative autologous blood donation, anticoagulation medications, sex, and body mass index. Pricing data was used to calculate the costs associated with these interventions. RESULTS: The likelihood of post-operative allogeneic blood transfusion was similar for the combined group relative to the TXA group (OR = 0.63; 95% CI: 0.26, 1.54), as was the likelihood of any post-operative blood transfusion (OR = 1.13; 95% CI: 0.63, 2.01). There was no correlative relationship between use of ICS and hematocrit drop when accounting for baseline hematocrit (R2 = 0.118). Factoring in rental, service fees, and disposable equipment, the utilization of ICS added $146 to each case, resulting in a gross expenditure of over $123,000 during the study period. CONCLUSIONS: The combination of ICS with TXA for primary unilateral THA did not improve blood loss or transfusion outcomes compared to TXA alone. As there was no observed clinical benefit to combined treatment, additional costs associated with routine usage of ICS may not be justifiable. Our institution would have reduced expenditures for blood loss management products by 85% during the study period if all patients had only received TXA.

Differences in Hospital Costs among Octogenarians and Nonagenarians Following Primary Total Joint Arthroplasty.

The proportion of patients over the age of 90 years continues to grow, and the anticipated demand for total joint arthroplasty (TJA) in this population is expected to rise concomitantly. As the country shifts to alternative reimbursement models, data regarding hospital expenses is needed for accurate risk-adjusted stratification. The aim of this study was to compare total in-hospital costs following primary TJA in octogenarians and nonagenarians, and to determine the primary drivers of cost. This was a retrospective analysis from a single institution in the U.S. We used time-drive activity-based costing (TDABC) to capture granular total hospital costs for each patient. 889 TJA's were included in the study, with 841 octogenarians and 48 nonagenarians. Nonagenarians were more likely to undergo total hip arthroplasty (THA) (70.8% vs. 42.4%; p < 0.0001), had higher ASA classification (2.6 vs. 2.4; p = 0.049), and were more often privately insured (35.4% vs. 27.8%; p = 0.0001) as compared to octogenarians. Nonagenarians were more often discharged to skilled nursing facilities (56.2% vs. 37.5%; p = 0.0011), experienced longer operating room (OR) time (142 vs. 133; p = 0.0201) and length of stay (3.7 vs. 3.1; p = 0.0003), and had higher implant and total in-hospital costs (p < 0.0001 and 0.0001). Multivariate linear regression showed implant cost (0.700; p < 0.0001), length of stay (0.546; p < 0.0001), and OR time (0.288; p < 0.0001) to be the strongest associations with overall costs. Primary TJA for nonagenarians was more expensive than octogenarians. Targeting implant costs, length of stay, and OR time can reduce costs for nonagenarians in order to provide cost-effective value-based care.
