Clinical implications of removing race-corrected pulmonary function tests for African American patients requiring surgery for lung cancer.
This study’s objective was to identify how many hospitals providing lung cancer surgery use race correction in pulmonary function tests (PFTs), examine the association of race correction with predicted lung function, and test the effect of decorrection on surgeons' treatment recommendations. Percent predicted preoperative and postoperative forced expiratory volume in 1 second (FEV1) was calculated for African American patients who underwent lung cancer resection between January 1, 2015, and September 31, 2022, using race-corrected and race-neutral equations for hospitals performing race correction. Randomization of US cardiothoracic surgeons was conducted to receive 1 clinical vignette that differed by the use of Global Lung Function Initiative equations for (1) African American patients (percent predicted postoperative FEV1, 49%), (2) other race or multiracial patients (percent predicted postoperative FEV1, 45%), and (3) race-neutral patients (percent predicted postoperative FEV1, 42%). A total of 515 African American patients (308 [59.8%] female; mean age, 66.2 years) were included in the study. Among these patients, the percent predicted preoperative FEV1 and postoperative FEV1 would have decreased by 9.2% and 7.6%, respectively, if race-neutral equations had been used. A total of 225 surgeons (194 male [87.8%]; mean time in practice, 19.4 years) were successfully randomized and completed the vignette items regarding risk perception and treatment outcomes (76% completion rate). Surgeons randomized to the vignette with African American race-corrected PFTs were more likely to recommend lobectomy (79.2%) compared with surgeons randomized to the other race or multiracial-corrected (61.7%) or race-neutral PFTs (52.8%).

Endometrial sampling for preoperative diagnosis of uterine leiomyosarcoma.
This retrospective cohort study examined the effectiveness of endometrial sampling for preoperative detection of uterine leiomyosarcoma in women undergoing hysterectomy, identified factors associated with missed diagnosis, and compared the outcomes of patients who had a preoperative diagnosis with those patients who had a missed diagnosis. A total of 79 patients with uterine leiomyosarcoma were included in the study. Of those patients, 46 (58.2%) were diagnosed preoperatively and 33 postoperatively. The groups were similar in age, race/ethnicity, bleeding symptoms, and comorbidities. Women who had endometrial sampling performed with hysteroscopy had a higher likelihood of preoperative diagnosis. Patients with localized stage (vs distant stage) or tumor size >11 cm were less likely to be diagnosed preoperatively.

Applying machine learning across sites: external validation of a surgical site infection detection algorithm.
Surgical complications have tremendous consequences and costs. Complication detection is important for quality improvement, but traditional manual chart review is burdensome. Automated mechanisms are needed to make this more efficient. The purpose of the study was to understand the generalizability of a machine learning algorithm between sites; automated surgical site infection (SSI) detection algorithms developed at one center were tested at another distinct center.

The quality of electrodiagnostic tests for carpal tunnel syndrome: Implications for surgery, outcomes, and expenditures.
The quality of electrodiagnostic tests may influence treatment decisions, particularly regarding surgery, affecting health outcomes and health-care expenditures. In this study, the investigators evaluated test quality among 338 adults with workers' compensation claims for carpal tunnel syndrome. The investigators found that in simulations, suboptimal quality tests rendered surgery inappropriate for 99 of 309 patients (+32 percentage points). They also found that test quality was not associated with overall health, actual receipt of surgery, or expenditures.

Cost-effectiveness of lobectomy versus genetic testing (Afirma(R)) for indeterminate thyroid nodules: considering the costs of surveillance.
This study evaluated whether diagnostic thyroidectomy for indeterminate thyroid nodules would be more cost-effective than genetic testing after including the costs of long-term surveillance. Its base case estimate suggests that diagnostic lobectomy dominates genetic testing as a strategy for ruling out malignancy of indeterminate thyroid nodules.

Failure to diagnose hyperparathyroidism in 10,432 patients with hypercalcemia: opportunities for system-level intervention to increase surgical referrals and cure.
Researchers sought to determine whether a significant number of patients with hyperparathyroidism remain undiagnosed and untreated. After reviewing administrative data on 682,704 patients from a tertiary referral center between 2011 and 2015 and identifying hypercalcemia (>10.5 mg/dL) in 10,432 patients, they concluded that a significant proportion of patients with hyperparathyroidism do not undergo appropriate evaluation and surgical referral.

Inter-rater agreement and checklist validation for postoperative wound assessment using smartphone images in vascular surgery.
The authors evaluated whether smartphone digital images can supplant in-person evaluation of postoperative vascular surgery wounds. They concluded that using smartphone digital images is a valid method for evaluating postoperative vascular surgery wounds and is comparable to in-person evaluation with regard to most wound characteristics. The inter-rater reliability for determining treatment recommendations was universally high.

Delay in diagnosis of invasive surgical site infections following knee arthroplasty versus hip arthroplasty.
The researchers compared time to diagnosis of invasive surgical site infection (SSI) following hip vs knee arthroplasty. They found that time to diagnosis of invasive SSI remained significantly shorter for hip than for knee arthroplasties after adjusting for age, pathogen virulence, and hospital surgical volume. They hypothesized that differences in symptom manifestation and disparities in access to care may contribute to the observed differential timing of diagnosis.
