Introduction: The National Trauma Research Action Plan convened 11 topic area panels to complete consensus-driven Delphi surveys to identify high priority trauma research questions. The Neurotrauma Panel identified questions relating to interventional and comparative effectiveness trials in severe traumatic brain injury (sTBI) critical care as highest priority. This qualitative secondary analysis aims to translate results across several Delphi panels into potential studies in sTBI critical care.

Materials and Methods This study retrospectively evaluated promising predictive models for lung cancer prediction in three clinical settings: lung cancer screening with low-dose CT, incidentally detected pulmonary nodules, and nodules deemed suspicious enough to warrant a biopsy. The area under the receiver operating characteristic curve of eight validated models, including logistic regressions on clinical variables and radiologist nodule characterizations, artificial intelligence (AI) on chest CT scans, longitudinal imaging AI, and multimodal approaches for prediction of lung cancer risk was assessed in nine cohorts ( = 898, 896, 882, 219, 364, 117, 131, 115, 373) from multiple institutions.

This study aimed to evaluate transportability of radiomic models across platforms by comparing performances of a commercial radiomic feature extractor (HealthMyne) with an open-source extractor (PyRadiomics) on diagnosis of lung cancer in IPNs.
Methods: A commercial radiomic feature extractor was used to segment IPNs from computed tomography (CT) scans, and a previously validated radiomic model based on commercial features was used as baseline (ComRad).
Background: Patients who are symptomatic from diaphragmatic dysfunction may benefit from diaphragmatic plication. We recently modified our plication approach from open thoracotomy to robotic transthoracic. We report our short-term outcomes.

This quasi-experimental study examines whether Medicaid expansion differentially increased the utilization of surgical cancer care for low-income groups and racial minorities in states that expanded their Medicaid programs.
Methods: A cohort of more than 81,000 patients 18 to 64 years of age who underwent cancer surgery were examined in Medicaid expansion versus nonexpansion states.
Background: The Affordable Care Act (ACA)'s Medicaid expansion has increased access to surgical care overall. Whether it was associated with reduced disparities in use of regionalized surgery at high-volume hospitals (HVH) remains unknown. Quasi-experimental evaluations of this expansion were performed to examine the use of regionalized surgery at HVH among racial/ethnic minorities and low-income populations.
View Article and Find Full Text PDFBackground: While pre-Affordable Care Act expansions in Medicaid eligibility led to increased utilization of elective inpatient procedures, the impact of the Affordable Care Act on such preference-sensitive procedures (also known as discretionary procedures) versus time-sensitive non-discretionary procedures remains unknown. As such, we performed a hospital-level quasi-experimental evaluation to measure the differential effects of the Affordable Care Act's Medicaid expansion on utilization of discretionary procedures versus non-discretionary procedures.
Methods: The State Inpatient Database (2012-2014) yielded 476 hospitals providing selected discretionary procedures or non-discretionary procedures performed on 288,446 non-elderly, adult patients across 3 expansion states and 2 non-expansion control states.
Background: The Affordable Care Act's Medicaid expansion has been heavily debated due to skepticism about Medicaid's ability to provide high-quality care. Particularly, little is known about whether Medicaid expansion improves access to surgical cancer care at high-quality hospitals. To address this question, we examined the effects of the 2001 New York Medicaid expansion, the largest in the pre-Affordable Care Act era, on this disparity measure.
View Article and Find Full Text PDFBackground: Although the Affordable Care Act (ACA) expanded Medicaid access, it is unknown whether this has led to greater access to complex surgical care. Evidence on the effect of Medicaid expansion on access to surgical cancer care, a proxy for complex care, is sparse. Using New York's 2001 statewide Medicaid expansion as a natural experiment, we investigated how expansion affected use of surgical cancer care among beneficiaries overall and among racial minorities.
