Key Points Question What is the optimal patient-centered approach to collecting sexual orientation and gender identity information in the emergency department? Findings In this matched cohort study of 540 adults, sexual and gender minority patients reported significantly higher patient satisfaction with registrar form collection compared with nurse verbal collection. Non–sexual and gender minority patients, in addition to those for whom sexual orientation and gender identity information was not collected, reported no worse outcomes with registrar form collection. Meaning Registrar form collection is the optimal patient-centered approach to collecting sexual orientation and gender identity information in the emergency department.

Next-generation therapeutics require advanced drug delivery platforms with precise control over morphology and release kinetics. A recently developed microfabrication technique enables fabrication of a new class of injectable microparticles with a hollow core-shell structure that displays pulsatile release kinetics, providing such capabilities. Here, we study this technology and the resulting core-shell microstructures. We demonstrated that pulsatile release is governed by a sudden increase in porosity of the polymeric matrix, leading to the formation of a porous path connecting the core to the environment. Moreover, the release kinetics within the range studied remained primarily independent of the particle geometry but highly dependent on its composition. A qualitative technique was developed to study the pattern of pH evolution in the particles. A computational model successfully modeled deformations, indicating sudden expansion of the particle before onset of release. Results of this study contribute to the understanding and design of advanced drug delivery systems.

BACKGROUND Trauma and emergency general surgery (EGS) patients who are uninsured have worse outcomes as compared with insured patients. Partially modeled after the 2006 Massachusetts Healthcare Reform (MHR), the Patient Protection and Affordable Care Act was passed in 2010 with the goal of expanding health insurance coverage, primarily through state-based Medicaid expansion (ME). We evaluated the impact of ME and MHR on outcomes for trauma patients, EGS patients, and trauma systems. METHODS This study was approved by the Eastern Association for the Surgery of Trauma Guidelines Committee. Using Grading of Recommendations Assessment, Development and Evaluation methodology, we defined three populations of interest (trauma patients, EGS patients, and trauma systems) and identified the critical outcomes (mortality, access to care, change in insurance status, reimbursement, funding). We performed a systematic review of the literature. Random effect meta-analyses and meta-regression analyses were calculated for outcomes with sufficient data. RESULTS From 4,593 citations, we found 18 studies addressing all seven predefined outcomes of interest for trauma patients, three studies addressing six of seven outcomes for EGS patients, and three studies addressing three of eight outcomes for trauma systems. On meta-analysis, trauma patients were less likely to be uninsured after ME or MHR (odds ratio, 0.49; 95% confidence interval, 0.37–0.66). These coverage expansion policies were not associated with a change in the odds of inpatient mortality for trauma (odds ratio, 0.96; 95% confidence interval, 0.88–1.05). Emergency general surgery patients also experienced a significant insurance coverage gains and no change in inpatient mortality. Insurance expansion was often associated with increased access to postacute care at discharge. The evidence for trauma systems was heterogeneous. CONCLUSION Given the evidence quality, we conditionally recommend ME/MHR to improve insurance coverage and access to postacute care for trauma and EGS patients. We have no specific recommendation with respect to the impact of ME/MHR on trauma systems. Additional research into these questions is needed. LEVEL OF EVIDENCE Review, Economic/Decision, level III
