Timely Second-Dose Completion of mRNA COVID-19 Vaccination at Community-Based and Mobile Vaccine Clinics in Maryland.

To assess factors associated with timely second-dose completion, we analyzed COVID-19 vaccine data from community-based and mobile vaccine clinics in Maryland. Overall, 85.3% of patients received a timely second dose. Factors associated with a timely second dose included Latino ethnicity (adjusted odds ratio [AOR] = 1.5; 95% confidence interval [CI] = 1.1, 2.0) and receipt of the first dose at community-based vaccine clinics (AOR = 2.1; 95% CI = 1.8, 2.5). Future health initiatives for underserved communities should focus on establishing vaccine clinics in trusted community spaces with culturally sensitive support.

A Path Forward: COVID-19 Vaccine Equity Community Education and Outreach Initiative.

COVID-19 vaccines offer hope to end the COVID-19 pandemic. In this article, we document key lessons learned as we continue to confront COVID-19 variants and work to adapt our vaccine outreach strategies to best serve our community. In the fall of 2020, the Office of Diversity, Inclusion and Health Equity at Johns Hopkins Medicine, in collaboration with the Office of Government and Community Affairs for Johns Hopkins University and Medicine, established the COVID-19 Vaccine Equity Community Education and Outreach Initiative in partnership with faith and community leaders, local and state government representatives, and community-based organizations. Working with community and government partnerships established before COVID-19 enabled our team to quickly build infrastructure focused on COVID-19 vaccine education and equity. These partnerships resulted in the development and implementation of web-based educational content, major culturally adapted media campaigns (reaching more than 200,000 individuals), community and faith education outreach, youth-focused initiatives, and equity-focused mobile vaccine clinics. The community mobile vaccine clinics vaccinated over 3,000 people in the first 3 months. Of these, 90% identified as persons of color who have been disproportionately impacted during the COVID-19 pandemic. Academic-government-community partnerships are vital to ensure health equity. Community partnerships, education events, and open dialogues were conducted between the community and medical faculty. Using nontraditional multicultural media venues enabled us to reach many community members and facilitated informed decisionmaking. Additionally, an equitable COVID-19 vaccine policy requires attention to vaccine access as well as access to sound educational information. Our initiative has been thoughtful about using various types of vaccination sites, mobile vaccine units, and flexible hours of operation.

A Community-Engaged Social Marketing Campaign to Promote Equitable Access to COVID-19 Services Among Latino Immigrants.

To address disparities in COVID-19 outcomes among Latinos with limited English proficiency in Maryland, our team developed a culturally congruent intervention that coupled a statewide social marketing campaign with community-based COVID-19 services. In the first year, we reached 305 122 people through social media advertisements and had 9607 visitors to the Web site. Social marketing campaigns represent an opportunity to promote COVID-19 testing and vaccine uptake among Latino populations, especially when they are paired with community services that simultaneously address structural barriers to care. (Am J Public Health. 2023;113(3):263-266. https://doi.org/10.2105/10.2105/AJPH.2022.307191).

Coalition of Faith Leaders, Community Organizations, and Governmental Organizations to Implement a COVID-19 Campaign in a Latino Neighborhood, Baltimore, Maryland, 2020-2021.

The disproportionate impact of COVID-19 on low-income Latinos with limited access to health care services prompted the expansion of community-based COVID-19 services. From June 25, 2020, to May 20, 2021, we established a coalition of faith leaders, community organizations, and governmental organizations to implement a Spanish-language hotline and social media campaign that linked people to a COVID-19 testing site at a local church in a high-density Latino neighborhood in Baltimore, Maryland. This retrospective analysis compared the characteristics of Latinos accessing testing in community versus health care facility-based settings.

High Uptake and Series Completion of COVID-19 Vaccine at Community-Based Vaccination for Latinos With Limited English Proficiency.

BACKGROUND: Despite the disproportionate impact of COVID-19 on Latinos, there were disparities in vaccination, especially during the early phase of COVID-19 immunization rollout. METHODS: Leveraging a community-academic partnership established to expand access to SARS-CoV2 testing, we implemented community vaccination clinics with multifaceted outreach strategies and flexible appointments for limited English proficiency Latinos. RESULTS: Between February 26 and May 7 2021, 2250 individuals received the first dose of COVID-19 vaccination during 18 free community events. Among them, 92.4% (95% confidence interval [CI], 91.2%-93.4%) self-identified as Hispanic, 88.7% (95% CI, 87.2%-89.9%) were limited English proficiency Spanish speakers, 23.1% (95% CI, 20.9%-25.2%) reported prior COVID-19 infection, 19.4% (95% CI, 16.9%-22.25%) had a body mass index of more than 35, 35.0% (95% CI, 32.2%-37.8%) had cardiovascular disease, and 21.6% (95% CI, 19.2%-24.0%) had diabetes. The timely second-dose completion rate was high (98.7%; 95% CI, 97.6%-99.2%) and did not vary by outreach method. CONCLUSION: A free community-based vaccination initiative expanded access for Latinos with limited English proficiency at high risk for COVID-19 during the early phase of the immunization program in the US.

Responding to the Disproportionate Impact of COVID-19 Among Latinx Patients in Baltimore: The JHM Latinx Anchor Strategy.

Latinx immigrants have been profoundly impacted by COVID-19. As the Johns Hopkins Health System faced a surge in admissions of limited English proficiency patients with COVID-19, it became evident that an institutional strategy to address the needs of this patient population was needed. The Johns Hopkins Medicine (JHM) Latinx Anchor Strategy was established in April 2020 with diverse stakeholder engagement to identify the most urgent community needs and develop timely solutions. The JHM Latinx Anchor Strategy provided a platform for information sharing to promote equitable access to resources for Latinxs with limited English proficiency who were impacted by COVID-19. Leveraging institutional, community, and government resources and expertise, the JHM Latinx Anchor Strategy helped establish interventions to improve access to COVID-19 testing and care for low-income immigrants without a primary care doctor and helped mitigate economic vulnerability through the distribution of food for 2,677 individuals and cash to 446 families and 95 individuals (May to August 2020). Expanded linguistic and culturally competent communication through webinars and livestream events reached more than 10,000 community members and partners. Over 7,500 limited English proficiency patients received linguistically congruent direct patient services through the Esperanza Center bilingual hotline, community testing resulting efforts, and inpatient consultations. The first stage of the JHM Latinx Anchor Strategy relied heavily on volunteer efforts. Funding for a sustainable response will be required to address ongoing COVID-19 needs, including expansion of the bilingual/bicultural healthcare workforce, expanded access to primary care, and investments in population health strategies addressing social determinants of health.

Evaluating immunity to SARS-CoV-2 in nursing home residents using saliva IgG.

BACKGROUND: SARS-CoV-2 circulating variants coupled with waning immunity pose a significant threat to the long-term care (LTC) population. Our objective was to measure salivary IgG antibodies in residents and staff of an LTC facility to (1) evaluate IgG response in saliva post-natural infection and vaccination and (2) assess its feasibility to describe the seroprevalence over time. METHODS: We performed salivary IgG sampling of all residents and staff who agreed to test in a 150-bed skilled nursing facility during three seroprevalence surveys between October 2020 and February 2021. The facility had SARS-CoV-2 outbreaks in May 2020 and November 2020, when 45 of 138 and 37 of 125 residents were infected, respectively; they offered two Federal vaccine clinics in January 2021. We evaluated quantitative IgG in saliva to the Nucleocapsid (N), Spike (S), and Receptor-binding domain (RBD) Antigens of SARS-CoV-2 over time post-infection and post-vaccination. RESULTS: One hundred twenty-four residents and 28 staff underwent saliva serologic testing on one or more survey visits. Over three surveys, the SARS-CoV-2 seroprevalence at the facility was 49%, 64%, and 81%, respectively. IgG to S, RBD, and N Antigens all increased post infection. Post vaccination, the infection naïve group did not have a detectable N IgG level, and N IgG levels for the previously infected did not increase post vaccination (p < 0.001). Fully vaccinated subjects with prior COVID-19 infection had significantly higher RBD and S IgG responses compared with those who were infection-naïve prior to vaccination (p < 0.001 for both). CONCLUSIONS: Positive SARS-COV-2 IgG in saliva was concordant with prior infection (Anti N, S, RBD) and vaccination (Anti S, RBD) and remained above positivity threshold for up to 9 months from infection. Salivary sampling is a non-invasive method of tracking immunity and differentiating between prior infection and vaccination to inform the need for boosters in LTC residents and staff.

Latino Household Transmission of Severe Acute Respiratory Syndrome Coronavirus 2.

We assessed temporal changes in the household secondary attack rate of severe acute respiratory syndrome coronavirus 2 and identified risk factors for transmission in vulnerable Latino households of Baltimore, Maryland. The household secondary attack rate was 45.8%, and it appeared to increase as the alpha variant spread, highlighting the magnified risk of spread in unvaccinated populations.

Extracorporeal Membrane Oxygenation Complications in Heparin- and Bivalirudin-Treated Patients.

Extracorporeal membrane oxygenation is a potentially life-saving intervention in refractory cardiopulmonary failure, but it requires anticoagulation to prevent circuit thromboses, which exposes the patient to hemorrhagic complications. Heparin has traditionally been the anticoagulant of choice, but the direct thrombin inhibitor bivalirudin is routinely used in cases of heparin-induced thrombocytopenia and has been suggested as a superior choice. We sought to examine the timing of hemorrhagic and thrombotic complications after extracorporeal membrane oxygenation cannulation and to compare the rates of such complications between patients anticoagulated with heparin versus bivalirudin. DESIGN: Retrospective cohort study. SETTING: Johns Hopkins Hospital patients between January 2016 and July 2019. PATIENTS: Adult (> 18 yr) extracorporeal membrane oxygenation patients. INTERVENTIONS: Patients were anticoagulated either with heparin or bivalirudin. MEASUREMENTS AND MAIN RESULTS: We compared rates of hemorrhagic and thrombotic complications by time on heparin versus bivalirudin and characterized the average time to each complication. Of 144 extracorporeal membrane oxygenation patients (mean age 55.3 yr; 58% male), 41% were on central venoarterial extracorporeal membrane oxygenation, 40% on peripheral venoarterial extracorporeal membrane oxygenation, and 19% on venovenous extracorporeal membrane oxygenation. Thirteen patients (9%) received bivalirudin during their extracorporeal membrane oxygenation run, due to concern for (n = 8) or diagnosis of (n = 4) heparin-induced thrombocytopenia or for heparin resistance (n = 1). The rate of hemorrhagic or thrombotic complications did not differ between heparin (0.13/d) and bivalirudin (0.06/d; p = 0.633), but patients on bivalirudin received significantly fewer blood transfusions (1.0 U of RBCs/d vs 2.9/d on heparin; p < 0.001). CONCLUSIONS: Our results confirm the safety and efficacy of bivalirudin as an alternative anticoagulant in extracorporeal membrane oxygenation and suggest a potential benefit in less blood product transfusion, although prospective studies are needed to evaluate the true effect of bivalirudin versus the disease processes that prompted its use in our study population.

Community Testing and SARS-CoV-2 Rates for Latinxs in Baltimore.

INTRODUCTION: Latinxs have been disproportionately impacted by COVID-19. Latinx immigrants, in particular, face significant barriers to SARS-CoV-2 testing, including lack of insurance, language barriers, stigma, work conflicts, and limited transportation. METHODS: In response to a disproportionately high SARS-CoV-2 positivity rate among Latinxs at the Johns Hopkins Health System, investigators implemented free community-based testing by partnering with religious leaders and leveraging the skill of trusted community health workers. Data were extracted from the electronic health record and a Research Electronic Data Capture database. SARS-CoV-2 positivity was evaluated per event stratified by race/ethnicity. Total rates of SARS-CoV-2 positivity and categorical patient characteristics were compared between groups using chi-square tests. RESULTS: Between June 25, 2020 and October 15, 2020, a total of 1,786 patients (57.5% Latinx, 31.2% non-Hispanic White, 5.9% non-Hispanic Black, and 5.3% non-Hispanic other) were tested for SARS-CoV-2 in 18 testing events. Among them, 355 (19.9%) tested positive. The positivity rate was 31.5% for Latinxs, 7.6% for non-Hispanic Blacks, 3.4% for non-Hispanic Whites, and 5.3% for patients of other races/ethnicities. Compared with Latinxs who tested negative, Latinxs who tested positive were more likely to report Spanish as their preferred language (91.6% vs 81.7%, p<0.001), be younger (30.4 vs 33.4 years, p<0.008), and have a larger household size (4.8 vs 4.3 members, p<0.002). CONCLUSIONS: Community-based testing identified high levels of ongoing SARS-CoV-2 transmission among primarily Latinxs with limited English proficiency. During this period, the overall positivity rate at this community testing site was almost 10 times higher among Latinxs than among non-Hispanic Whites.

Bibliometric Review of Medical Student Research Before Matching Integrated Vascular Surgery.

BACKGROUND: Research output is one element of a multifactorial process that residency programs consider when evaluating applicants. However, there are minimal data assessing research productivity on admittance into research-oriented integrated vascular surgery residency (RO-IVSR) programs. The purpose of this study was to evaluate the association of peer-reviewed research and the RO-IVSR match process. MATERIAL AND METHODS: Vascular surgery residents who matched into an RO-IVSR in 2015-2017 were divided into those matching an RO-IVSR top 10 program versus other. Total publications, first authorships, and type of research were compared between groups. Mann-Whitney U-tests were then performed between discrete levels of research productivity (0-1 versus ≥2 publications) to detect differences in ability to match a top 10 program. RESULTS: One hundred and fifty-eight residents published a total of 214 original research articles (83%), 26 case reports (10%), and 19 systematic reviews (7%). There were 66 first authorships (25%). Median total publications at RO-IVSR top 10 versus other programs were 2 versus 1 (P < 0.01). Top 10 IVSR had a significant difference in median publications for all other research categories. The ability to match into a top 10 program by discrete levels of research productivity at 0-1 versus 2+ showed significance (P < 0.05) in all research categories, including total publications, first authorships, and H-index. CONCLUSIONS: There was significantly higher research productivity among medical students who matriculate to top 10 IVSR programs. Furthermore, having 2 or more publications significantly increased the likelihood of attending a top 10 program. Thus, top programs likely use an applicants' research productivity as a distinct qualification category and a marker of future success.

Medical Student Research Productivity: Which Variables are Associated with Matching to a Highly Ranked Orthopaedic Residency Program?

OBJECTIVE: Little is known about the importance of an applicant's research productivity in terms of matching into a highly-ranked orthopaedic residency. We characterized the research of orthopaedic residents who matched in 2017 to determine whether 1) program tiers differed by their residents' research; and 2) discrete increases in applicants' research were associated with matching into higher-ranked programs. DESIGN: We searched Scopus for resident publications accepted before 2017 or published through January 2017. Using an established ranking system, programs were ranked (tier-1, highest; tier-5, lowest) by their department's number of citations from 2005 to 2015. We compared resident research productivity among these 5 tiers. We then categorized residents by discrete levels of research productivity (0, 1, or ≥2 publications) and compared the differences in matched program rank. SETTING: Data collection and analysis performed at Johns Hopkins Hospital, a tertiary care center in Baltimore, MD. PARTICIPANTS: We obtained our sample from allopathic orthopaedic program websites, excluding military programs and international students, for a total of 111 programs (565 of 726 matched residents [78%]). RESULTS: Tier-1 and tier-2 programs differed significantly in their residents' publications, h-index, and citations. Programs of other tiers did not differ significantly. Applicants with 1 publication matched to higher-ranked residency programs than those with 0 publications. When comparing residents with 1 publication versus residents with more than 1 publication, we found no significant differences in program rank matched. CONCLUSIONS: Our results suggest that higher-tier orthopaedic residency programs match residents with greater research productivity than do lower-tier programs. Having 1 publication was associated with matching into a higher-ranked program but no significant associations were observed beyond the first publication.

Outcomes of Nursing Home COVID-19 Patients by Initial Symptoms and Comorbidity: Results of Universal Testing of 1970 Residents.

OBJECTIVE: Clinical implications of asymptomatic cases of the novel coronavirus disease 2019 (COVID-19) in nursing homes remain poorly understood. We assessed the association of symptom status and medical comorbidities on mortality and hospitalization risk associated with COVID-19 in residents across 15 nursing homes in Maryland. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: 1970 residents from 15 nursing home facilities with universal COVID-19 testing in Maryland. METHODS: We used descriptive statistics to compare baseline characteristics, logistic regression to assess the association of comorbidities with COVID-19, and Cox regression to assess the association of asymptomatic and symptomatic COVID-19 with mortality and hospitalization. We assessed the association of comorbidities with mortality and hospitalization risk. Symptom status was assessed at the time of the first test. Maximum follow-up was 94 days. RESULTS: Among the 1970 residents (mean age 73.8, 57% female, 68% black), 752 (38.2%) were positive on their first test. Residents who were positive for COVID-19 and had multiple symptoms at the time of testing had the highest risk of mortality [hazard ratio (HR) 4.44, 95% confidence interval (CI) 2.97, 6.65) and hospitalization (subhazard ratio 2.38, 95% CI 1.70, 3.33), even after accounting for comorbidity burden. Cases who were asymptomatic at testing had a higher risk of mortality (HR 2.92, 95% CI 1.95, 4.35) but not hospitalization (HR 1.06, 95% CI 0.82, 1.38) compared with those who were negative for COVID-19. Of 52 SARS-CoV-2-positive residents who were asymptomatic at the time of testing and were closely monitored for 14 days at one facility, only 6 (11.6%) developed symptoms. CONCLUSIONS AND IMPLICATIONS: Asymptomatic infection with SARS-CoV-2 in the nursing home setting was associated with increased risk of death, suggesting a need for closer monitoring of these residents, particularly those with underlying cardiovascular and respiratory comorbidities.

Transmission of SARS-CoV-2 Involving Residents Receiving Dialysis in a Nursing Home - Maryland, April 2020.

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), can spread rapidly in nursing homes once it is introduced (1,2). To prevent outbreaks, more data are needed to identify sources of introduction and means of transmission within nursing homes. Nursing home residents who receive hemodialysis (dialysis) might be at higher risk for SARS-CoV-2 infections because of their frequent exposures outside the nursing home to both community dialysis patients and staff members at dialysis centers (3). Investigation of a COVID-19 outbreak in a Maryland nursing home (facility A) identified a higher prevalence of infection among residents undergoing dialysis (47%; 15 of 32) than among those not receiving dialysis (16%; 22 of 138) (p<0.001). Among residents with COVID-19, the 30-day hospitalization rate among those receiving dialysis (53%) was higher than that among residents not receiving dialysis (18%) (p = 0.03); the proportion of dialysis patients who died was 40% compared with those who did not receive dialysis (27%) (p = 0.42).Careful consideration of infection control practices throughout the dialysis process (e.g., transportation, time spent in waiting areas, spacing of machines, and cohorting), clear communication between nursing homes and dialysis centers, and coordination of testing practices between these sites are critical to preventing COVID-19 outbreaks in this medically vulnerable population.

Analyzing Outcomes of Nuss and Ravitch Repair for Primary and Recurrent Pectus Excavatum in Adults.

BACKGROUND: Limited data exist for pectus excavatum repair in adults. We reviewed outcomes in adult patients undergoing Ravitch or Nuss pectus excavatum repairs to determine whether there was a statistical difference in postoperative complications and recurrence between primary and redo operations. METHODS: Patients undergoing pectus excavatum repair between 2001 and 2018 were excluded if they were receiving a concurrent unrelated operation, aged younger than 18 years, or had less than 1 year of follow-up (for recurrence analysis). Postoperative complications were recorded based on procedure type (Ravitch/Nuss) and iteration of repair (primary/redo). Continuous patient data were compared using Student t tests for variables such as age, length of stay, estimated blood loss, body mass index, and number of bars inserted. Fisher exact or χ2 tests were performed for postoperative complications and recurrence rates between groups. RESULTS: Of 290 patients, there were no significant differences in postoperative complications or recurrence rates between all Nuss repairs (n = 237; P = .59) and all Ravitch repairs (n = 53; P = .48), redo Nuss repairs (n = 53; P = .26) and Ravitch repairs (n=26; P = .99), and primary (P = .26) and redo Nuss (P = .10) repairs or primary (P = .99) and redo Ravitch (P = .99) repairs. There were significant differences in age, length of stay, follow-up, bars inserted, and estimated blood loss between all Nuss and Ravitch repairs (P < .05). CONCLUSIONS: Postoperative complication and recurrence rates were not statistically different between Nuss and Ravitch procedures of all types, suggesting either procedure may have utility in recurrent pectus excavatum. Further research may look to expand sample size and a prospective study investigating long-term outcomes.
