Pandemic phase-related racial and ethnic disparities in COVID-19 positivity and outcomes among patients presenting to emergency departments during the first two pandemic waves in the USA.

BACKGROUND: In many countries including the USA, the UK and Canada, the impact of COVID-19 on people of colour has been disproportionately high but examination of disparities in patients presenting to ED has been limited. We assessed racial and ethnic differences in COVID-19 positivity and outcomes in patients presenting to EDs in the USA, and the effect of the phase of the pandemic on these outcomes. METHODS: This is a retrospective cohort study of adult patients tested for COVID-19 during, or 14 days prior to, the index ED visit in 2020. Data were obtained from the National Registry of Suspected COVID-19 in Emergency Care network which has data from 155 EDs across 27 US states. Hierarchical models were used to account for clustering by hospital. The outcomes included COVID-19 diagnosis, hospitalisation at index visit, subsequent hospitalisation within 30 days and 30-day mortality. We further stratified the analysis by time period (early phase: March-June 2020; late phase: July-September 2020). RESULTS: Of the 26 111 adult patients, 38% were non-Hispanic White (NHW), 29% Black, 20% Hispanic/Latino, 3% Asian and 10% all others; half were female. The median age was 56 years (IQR 40-69), and 53% were diagnosed with COVID-19; of those, 59% were hospitalised at index visit. Of those discharged from ED, 47% had a subsequent hospitalisation in 30 days. Hispanic/Latino patients had twice (adjusted OR (aOR) 2.3; 95% CI 1.8 to 3.0) the odds of COVID-19 diagnosis than NHW patients, after adjusting for age, sex and comorbidities. Black, Asian and other minority groups also had higher odds of being diagnosed (compared with NHW patients). On stratification, this association was observed in both phases for Hispanic/Latino patients. Hispanic/Latino patients had lower odds of hospitalisation at index visit, but when stratified, this effect was only observed in early phase. Subsequent hospitalisation was more likely in Asian patients (aOR 3.1; 95% CI 1.1 to 8.7) in comparison with NHW patients. Subsequent ED visit was more likely in Blacks and Hispanic/Latino patients in late phase. CONCLUSION: We found significant differences in ED outcomes that are not explained by comorbidity burden. The gap decreased but persisted during the later phase in 2020.

Access to primary care services using public transport in Otautahi Christchurch.

AIMS: Lack of transport is a contributor to poor access to healthcare and missed appointments. This research aimed to understand the accessibility of primary care for patients using public transport in Otautahi Christchurch, and to describe spatial and social distribution. METHODS: We measured access to primary care using geospatial analysis based on the time taken to reach the nearest general practice, the number of practices accessible within given time thresholds and the frequency of public transport services. Results are disaggregated by ethnicity, age, socioeconomic deprivation and car ownership. RESULTS: The poorest levels of access were in areas with the least deprivation and a greater NZ European population. Children aged 5-14 had low levels of access. Only 58.4% of the population in the most deprived areas had access to high-frequency bus services. CONCLUSIONS: This study highlights connectivity gaps between public transport and primary healthcare for key groups known to have a greater dependence upon public transport and poorer health outcomes. From an equity perspective, it highlights the need for further investigation into transport and health solutions to improve access to primary care for lower socioeconomic groups.

Acute Necrotizing Encephalopathy: 2 Case Reports on RANBP2 Mutation.

Infection-induced acute encephalopathy 3 (IIAE3) is an autosomal dominant disease resulting from a pathogenic variant in the RANBP2 gene. IIAE3 results in the susceptibility to the recurrence of acute necrotizing encephalopathy (ANE1) which presents as bilateral symmetric thalamic, midbrain and/or hindbrain lesions that typically develops within 1-4 days post-acute viral infection, commonly occurring before age 6.1-6 These case reports highlight a retrospective analysis of clinical data and radiographic studies on 2 ANE1 cases from our institution. The novel p.Leu450Phe variant of the RANBP2 gene was analyzed using in silico algorithms (PolyPhen-2, SIFT, Mutationtaster) which suggests the p.Leu450Phe variant is probably deleterious.7 An expansion of documented ANE1 case presentations and clinically significant RANBP2 gene mutations has the potential to improve long term outcomes if more informed therapeutic decision making can be achieved.

Trends in Gender Representation and Post-residency In-State Retention at Both an Academic Medical Center and in the United States.

This study examines gender representation and in-state retention rates of practicing residency graduates from Pennsylvania State University (PSU), as well as at the national level. PSU and national data were collected from a PSU handbook and the Association of American Medical Colleges (AAMC), respectively. There were significant differences between male and female representation both at PSU and at the national level. Furthermore, there was a significant difference between male and female retention rates nationally. This study demonstrates a true gender discrepancy for graduates from PSU and at the national level. Moving forward, investigating potential causes of this discrepancy may help minimize gender differences.
