Characteristics and Health Care Utilization of Patients With Housing Insecurity in the ED.

Importance: Unstable housing and homelessness can exacerbate adverse health outcomes leading to increased risk of chronic disease, injury, and disability. However, emergency departments (EDs) have no universal method to identify those at risk of or currently experiencing homelessness. Objective: To describe the extent of housing insecurity among patients who seek care in an urban ED, including chief concerns, demographics, and patterns of health care utilization. Design, Setting, and Participants: This cross-sectional study included all adult patients presenting to the ED at Vanderbilt University Medical Center (VUMC), an urban tertiary care, level I trauma center in the Southeast US, from January 5 to May 16, 2023. Main Outcomes and Measures: The primary outcome was the proportion of ED visits at which patients screened positive for housing insecurity. Secondary outcomes included prevalence of insecurity by chief concerns, demographics, and patterns of health care utilization. Results: Of all 23 795 VUMC ED visits with screenings for housing insecurity (12 465 visits among women [52%]; median age, 47 years [IQR, 32-48 years]), in 1185 (5%), patients screened positive for current homelessness or housing insecurity (660 unique patients); at 22 610 visits (95%), the screening result was negative. Of visits with positive results, the median age of patients was 46 years (IQR, 36-55 years) and 829 (70%) were among male patients. Suicide and intoxication were more common chief concerns among visits at which patients screened positive (132 [11%] and 118 [10%], respectively) than among those at which patients screened negative (220 [1%] and 335 [2%], respectively). Visits with positive results were more likely to be among patients who were uninsured (395 [33%] vs 2272 [10%]) and had multiple visits during the study period. A higher proportion of positive screening results occurred between 8 pm and 6 am. The social work team assessed patients at 919 visits (78%) with positive screening results. Conclusions and Relevance: In this cross-sectional study of 23 795 ED visits, at 5% of visits, patients screened positive for housing insecurity and were more likely to present with a chief concern of suicide, to be uninsured, and to have multiple visits during the study period. This analysis provides a call for other institutions to introduce screening and create tailored care plans for patients experiencing housing insecurity to achieve equitable health care.

Pulmonary valve replacement for treatment of severe pulmonary regurgitation in patients with previous tetralogy of Fallot repair surgery.

Tetralogy of Fallot was classically described as the combination of pulmonary stenosis, right ventricle hypertrophy, perimembranous ventricular septal defect and an aortic root that overrides the ventricular septal defect. Full surgical repair, which is usually indicated in toddlers, comprises closure of the ventricular septal defect and alleviation of the pulmonary stenosis. Because there is a wide anatomical spectrum, the cause and severity of the pulmonary stenosis are variable. However, when the pulmonary valve is stenotic and not well-developed, it has to be removed, and one has to accept severe pulmonary regurgitation as a sequela. In the ensuing years, when signs of damage to the right ventricle are proven, pulmonary valve replacement is indicated. We present the case of a 16-year-old patient with tetralogy of Fallot that was corrected during the first year of life. Follow-up demonstrated progressive exercise intolerance and moderate-to-severe right ventricle dilatation. Thus, surgical pulmonary valve replacement was indicated. The surgical approach was through a full median redo sternotomy. Central cardiopulmonary bypass was established with bicaval drainage. The operation was performed under assisted non-clamped circulatory support. The calcified previous pericardial patch was removed, and a 25-mm bioprosthetic valve was implanted in the pulmonary annulus. A new pericardial heterologous patch was used for the transannular pulmonary plasty.

Zooming into the COVID Era Together.

The pre-clinical medical school curriculum provides students with extraordinary experiences in preparation to become physicians. However, it was not originally designed to be delivered remotely. The COVID-19 pandemic promptly threw the medical education process into unforeseen circumstances. A model of student-faculty collaboration created to address new challenges and implement practical solutions rapidly is presented. This model was used effectively to respond to pre-clinical educational interruptions that were imposed by the COVID-19 pandemic and maintain high-quality training. Our experience provides valuable insights and lessons learned that can be applied to the ongoing pandemic response and to future educational challenges.
