Are Patients without Insurance Coverage Less Likely to Undergo Surgery for Humeral Shaft Fractures? A National Database Analysis.

BACKGROUND: Historically, humeral shaft fractures have been managed non-operatively in a functional brace. However, recent studies suggest an increase in rates of operative fixation. Disparities in surgical management based on insurance status have been demonstrated across many orthopedic conditions. This study aimed to identify if a correlation exists between insurance coverage and the probability of undergoing operative fixation for a humeral shaft fracture. METHODS: A retrospective examination of the National Readmissions Database (NRD) from 2016 to 2021 was conducted. Patients diagnosed with isolated closed humeral shaft fractures were identified via International Classification of Disease, Tenth Revision (ICD-10) codes, and surgical interventions were identified using ICD-10 procedural codes. Utilizing weighted data, a total of 56,468 patients with isolated closed humeral shaft fractures were identified, 25,075 (44.4%) of whom underwent operative fixation. A univariate analysis was conducted using Pearson's chi-square test to isolate variables for inclusion in a multi-variable analysis. A binary logistic regression analysis was then employed to explore demographic and other pertinent factors. Findings were reported as odds ratios (ORs). RESULTS: After controlling for social and demographic variables, patients with Medicaid (OR, 0.54; 95% CI, 0.50-0.58; p<0.001), Medicare (OR, 0.64; 95% CI, 0.60 - 0.68; p<0.001), and self-pay patients (OR, 0.75; 95% CI, 0.67 - 0.84; p<0.001) were less likely to undergo operative fixation of humeral shaft fracture than those with private insurance. CONCLUSIONS: Patients without private insurance or those with no insurance coverage are less likely to undergo operative fixation for humeral shaft fractures compared to those with private insurance, even after adjusting for social and demographic variables. The observed variability underscores the necessity for more refined treatment guidelines for humeral shaft fractures. Surgeons should be aware of these potential biases affecting management decisions.

Short Interval Staged Bilateral Total Knee Arthroplasty: Safety Compared to Simultaneous and Later Staged Bilateral Total Knee Arthroplasty.

BACKGROUND: Simultaneous bilateral total knee arthroplasty (sim-BTKA) is reported to be safe in a select group of patients. Patients with symptomatic bilateral knee arthritis who are not candidates for sim-BTKA require staged surgery (stag-BTKA). This study aimed to compare the safety and complications associated with sim-BTKA with stag-BTKA performed at 2 time intervals. METHODS: This retrospective study of prospectively collected data includes bilateral TKA cases performed between 2001 and 2019. A cohort of sim-BTKA (n = 2728) was compared to a cohort of stag-BTKA (n = 1658). The staged group was subdivided according to the interval between surgeries: ≤90 days (early) and ≥91 days (later). Multivariate logistic regression analyses were used to adjust for confounding variables. RESULTS: In-hospital complication rates were lower in both arms of the stag-BTKA groups vs the sim-BTKA. The sim-BTKA group had higher odds ratio of anemia, electrolyte disturbances, pulmonary embolism, and respiratory, urinary, gastrointestinal, and neurological complications. Lower rates of all-cause revision were found in stag-BTKA vs sim-BTKA groups. There was a trend toward revision due to deep infection when increasing the interim before the second stag-BTKA procedure. No differences in complication rates after the second surgery were detected between the early and later stag-BTKA. CONCLUSION: This study demonstrates that sim-BTKA is associated with more complications and revisions when compared to stag-BTKA. Performing the second-stage TKA at 90 days or less after the first TKA is not associated with increased risk of complications. Performing sim-BTKA, simply for convenience, is not warranted and should be reserved for a select group of patient matching specific criteria.

Use of Triggers to Detect Adverse Events After Outpatient Orthopedic Surgery at a Single Ambulatory Surgery Center.

Literature on adverse events (AEs) after outpatient orthopedic surgery is relatively sparse, and efforts to detect, measure, and track AEs after outpatient surgery lag behind those for the inpatient setting. Detection of AEs has traditionally relied on patient safety indicators (from billing data) and self-reporting, but these methods have been shown to have low sensitivity, missing up to 90% of AEs. There is growing recognition that the trigger method, which uses "triggers" as red flags to initiate more detailed chart audits, can serve as a more sensitive alternative to detect AEs. Moreover, the recent widespread adoption of electronic health records (EHRs) can provide faster automated methods for identifying triggers and estimating AE rates. This study evaluates the ability of 6 separate EHR-based triggers to predict AEs after outpatient orthopedic surgery and compares this trigger method with AE self-reporting. Triggers have the potential to decrease postoperative morbidity after outpatient orthopedic surgery and may lead to quality improvement. Further research is needed to qualify triggers as screening tools in the outpatient setting. [Orthopedics. 2022;45(2):116-121.].

An Evaluation of Complications Following Ultrasound-Guided Regional Block Anesthesia in Outpatient Hand Surgery.

Background: Ultrasound-guided (USG) assistance has contributed to the acceptance of regional anesthesia as a safe and efficient alternative to traditional general anesthesia. However, limited data exist regarding the safety of supraclavicular blocks used in common hand surgery procedures. The purpose of this retrospective study was to evaluate a large sample of cases to determine the effectiveness and complication rate of supraclavicular nerve blocks and confirm the safety of its use within the ambulatory surgery center (ASC) setting. Methods: Nerve blocks for the upper extremity were performed via the supraclavicular approach using the USG technique. Records were analyzed for all patients monitored during the immediate postoperative recovery and step-down phases at the ASC and contacted by phone or evaluated within 2 weeks at their first postoperative visit. Adverse outcomes related to the regional block anesthesia were identified via phone interview or postoperative surgical visit and documented. Results: In all, 713 records were reviewed with 56% female (n = 398) and 44% male (n = 315) patients. Of the 713 cases, 4 adverse events were identified (0.6%, 95% confidence interval [%]), including 2 abnormal reactions to the nerve block and 2 incomplete blocks with inadequate pain control. Conclusions: This study is the first report to evaluate a large sample of outpatient hand procedures at a high-volume ASC. We can report no clinically significant pulmonary or neurovascular complications with the use of USG supraclavicular nerve block techniques, further supporting its establishment as a safe and efficient procedure, yielding a low complication rate.

Radiologic Measurements in the Assessment of Patellar Instability: A Systematic Review and Meta-analysis.

BACKGROUND: Numerous diagnostic imaging measurements related to patellar instability have been evaluated in the literature; however, little has been done to compare these findings across multiple studies. PURPOSE: To review the different imaging measurements used to evaluate patellar instability and to assess the prevalence of each measure and its utility in predicting instability. We focused on reliability across imaging modalities and between patients with and without patellar instability. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: We performed a systematic review of the literature using the PubMed, SCOPUS, and Cochrane databases. Each database was searched for variations of the terms "patellar instability," "patellar dislocation," "trochlear dysplasia," "radiographic measures," "computed tomography," and "magnetic resonance imaging." Studies were included if they were published after May 1, 2009, and before May 1, 2019. A meta-analysis using a random effects model was performed on several measurements, comparing instability and control groups to generate pooled values. RESULTS: A total of 813 articles were identified, and 96 articles comprising 7912 patients and 106 unique metrics were included in the analysis. The mean patient age was 23.1 years (95% CI, 21.1-24.5), and 41% were male. The tibial tubercle-trochlear groove (TT-TG) distance was the most frequently included metric (59 studies), followed by the Insall-Salvati ratio and Caton-Deschamps index (both 26 studies). The interobserver intraclass correlation coefficients were excellent or good for the TT-TG distance and Insall-Salvati ratio in 100% of studies reporting them; however, for the Caton-Deschamps index and Blackburne-Peel ratio, they were excellent or good in only 43% and 40% of studies. Pooled magnetic resonance imaging values for TT-TG distance (P < .01), Insall-Salvati ratio (P = .01), and femoral sulcus angle (P = .02) were significantly different between the instability and control groups. Values for tibial tubercle-posterior cruciate ligament distance (P = .36) and Caton-Deschamps index (P = .09) were not significantly different between groups. CONCLUSION: The most commonly reported measurements for evaluating patellar instability assessed patellar tracking and trochlear morphology. The TT-TG distance was the most common measurement and was greater in the patellar instability group as compared with the control group. In addition, the TT-TG, tibial tubercle-posterior cruciate ligament, and patellar tendon-trochlear groove distances were highly reproducible measurements for patellar tracking, and the Insall-Salvati ratio had superior reproducibility for assessing patellar height.

Clinical Outcomes of Eyes With Diabetic Macular Edema Switched From Aflibercept to Ranibizumab Therapy.

BACKGROUND AND OBJECTIVE: In 2018, cases of inflammation were reported after intravitreal aflibercept (IVA), which resulted in switches to intravitreal ranibizumab (IVR). The authors' purpose was to evaluate outcomes after switching from IVA to IVR in diabetic macular edema (DME). PATIENTS AND METHODS: Retrospective cohort study. Eyes switched from IVA to IVR for treating DME were included. Data were gathered from three visits before to three visits post-switch. Outcome measures included central subfoveal thickness (CFT) and Snellen visual acuity (VA). RESULTS: There was a statistically significant increase in CFT at the first visit (325 µm ± 234 µm; P = .006) compared to the switch visit, but no difference later visits (268 µm ± 103 µm; P = .32; 284 µm ± 118 µm; P = .11; n = 54). There was no statistically significant change in mean logarithm of the minimum angle of resolution VA between the switch and later visits (0.43 ± 0.38, P = .95; 0.38 ± 0.30, P = .12; 0.41 ± 0.37, P = .69). CONCLUSIONS: The authors observed transient worsening of macular edema in eyes treated for DME when switched from aflibercept to ranibizumab. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:691-697.].
