Farmworker Mobility and COVID-19 Vaccination Strategies: Yuma County, Arizona, 2021.

Farmworkers, a group of essential workers, experience a disproportionately high burden of COVID-19 due to their living and working conditions. This project characterized farmworker mobility in and around Yuma County, Arizona, to identify opportunities to improve farmworker access to COVID-19 vaccination. We collected qualitative and geospatial data through a series of in-person and virtual focus group discussions, key informant interviews, and intercept interviews with participatory mapping. Participants included farmworkers, employers, and representatives of local institutions who serve or interact with farmworkers. We identified participants through purposive and referential sampling and grouped people by sociodemographic characteristics for interviews. We used qualitative and geospatial analyses to identify common themes and mobility patterns. The team interviewed 136 people from February 26 to April 2, 2021. Common themes emerged about how farmworkers have little or no access to COVID-19 vaccination unless offered at their workplaces or at locations where they congregate at convenient times. Further, farmworkers described how their demanding work schedules, long commute times, and caretaker commitments make it challenging to access vaccination services. Geospatial analyses identified three geographic areas in Yuma County where farmworkers reported living and working that did not have a COVID-19 vaccine clinic within walking distance. Coordination between local public health authorities and key partners, including employers and trusted representatives from local community-based organizations or the Mexican consulate, to offer vaccination at worksites or other locations where farmworkers congregate can help improve access to COVID-19 vaccines and booster doses for this population.

Is boarding compromising our residents' education? A national survey of emergency medicine program directors.

Background: Boarding patients in the emergency department (ED) potentially affects resident education. Program director (PD) perceptions of the impact of boarding on their trainees have not been previously described. Methods: We surveyed a cross-sectional convenience sample of emergency medicine PDs using a mixed-methods approach to explore their perceptions of how boarding has affected their residents' training. Descriptive data were reported as percentages and differences were calculated using Pearson's chi-square test, with p < 0.05 considered significant. A framework model was used to qualitatively analyze free-text responses. Results: A total of 170 responses were collected, for a response rate of 63%. Most respondents felt that boarding had at least some effect on resident education with 29%, 35%, 18%, and 12% noting "a little," "a moderate amount," "a lot," and "a great deal," respectively, and 5% noting "no effect at all." Respondents perceived a negative impact of boarding on resident education and training, with 80% reporting a "somewhat" or "extremely negative" effect, 18% feeling neutral, and 2% noting a "somewhat positive" effect. Most noted a "somewhat" or "extremely negative" effect on resident education in managing ED throughput (70%) and high patient volumes (66%). Fifty-four percent noted a "somewhat" or "extremely negative" impact on being involved in the initial workup of undifferentiated patients. Thirty-two percent saw a "somewhat" or "extremely positive" effect on learning the management of critically ill patients. Qualitative analysis of challenges, mitigation strategies, and resident feedback emphasized the lack of exposure to managing departmental patient flow, impact on bedside teaching, and need for flexibility in resident staffing. Conclusions: Most PDs agree that boarding negatively affects resident education and identify several strategies to mitigate the impact. These findings can help inform future interventions to optimize resident learning in the complex educational landscape of high ED boarding.

Interest and Satisfaction of Telemedicine Use Among Ambulatory Neurology Patients in Western North Carolina During the COVID-19 Pandemic.

Introduction: During the COVID-19 pandemic, care shifted from exclusively telemedicine to hybrid models with in-person, video, and telephone visits. We explored how patient satisfaction and visit preferences have changed by comparing in-person versus virtual visits (telephone and video) in an ambulatory neurology practice across three time points. Methods: Patients who completed a virtual visit in March 2020 (early-pandemic), May 2020 (mid-pandemic), and March 2021 (later-pandemic) were contacted. Patients were assessed for visit satisfaction and desire for future telemedicine. Univariate and multivariable logistic regression analysis was conducted to determine factors independently associated with video visit completion. Results: Four thousand seven hundred seventy-eight the number of ambulatory visits (n = 4,778) were performed (1,004 early; 1,265 mid; and 2,509 later); 1,724 patients (36%) assented to postvisit feedback; mean age 45.8 ± 24.4 years, 58% female, 79% white, and 56% with Medicare/Medicaid insurance. Patient satisfaction significantly increased (73% early, 79% mid, 81% later-pandemic, p = 0.008). Interest in telemedicine also increased for patients completing telephone visits (40% early, 50% mid, 59% later, p = 0.027) and video visits (52% early, 59% mid, 62% later, p = 0.035). Patients satisfied with telemedicine visits were younger (p < 0.001). White patients were more interested in future telemedicine (p = 0.037). Multivariable analysis showed that older patients (for each 1 year older), Black patients, and patients with Medicare/Medicaid were 2%, 45%, and 54% less likely to complete a video visit than telephone, respectively. Discussion: Patients, especially younger ones, have become more satisfied and more interested in hybrid care models during the COVID-19 pandemic. Barriers to conducting video visits persist for older, Black patients with Medicare or Medicaid insurance.

Progress Toward Measles and Rubella Elimination - Indonesia, 2013-2022.

In 2019, Indonesia and the other countries in the World Health Organization South-East Asia Region adopted the goal of measles and rubella elimination by 2023. This report describes Indonesia's progress toward measles and rubella elimination during 2013-2022. During this period, coverage with a first dose of measles-containing vaccine (MCV) decreased from 87% to 84%, and coverage with a second MCV dose decreased from 76% to 67%. After rubella vaccine was introduced in 2017, coverage with the first dose of rubella-containing vaccine increased approximately fivefold, from 15% in 2017 to 84% in 2022. During 2013-2021, annual reported measles incidence decreased by 95%, from 33.2 to 1.4 cases per million population; reported rubella incidence decreased 89%, from 9.3 to 1.0 cases per million population. However, a large surge in measles and rubella cases occurred in 2022, with a reported measles incidence of 29 cases per million and a reported rubella incidence of 3 per million, primarily related to disruption in immunization services caused by the COVID-19 pandemic. In 2022, approximately 26 million children (an estimated 73% of the target population) received a combined measles- and rubella-containing vaccine during supplementary immunization activities completed in 32 provinces. Progress toward measles and rubella elimination in Indonesia has been made; however, continued and urgent efforts are needed to restore routine immunization services that were adversely affected by the COVID-19 pandemic and close immunity gaps to accelerate progress toward measles and rubella elimination.

A characterization of cross-border use of health services in a transborder population at the Mexico-Guatemala border, September-November 2021.

BACKGROUND: Cross-border use of health services is an important aspect of life in border regions. Little is known about the cross-border use of health services in neighboring low- and middle-income countries. Understanding use of health services in contexts of high cross-border mobility, such as at the Mexico-Guatemala border, is crucial for national health systems planning. This article aims to describe the characteristics of the cross-border use of health care services by transborder populations at the Mexico-Guatemala border, as well as the sociodemographic and health-related variables associated with use. METHODS: Between September-November 2021, we conducted a cross-sectional survey using a probability (time-venue) sampling design at the Mexico-Guatemala border. We conducted a descriptive analysis of cross-border use of health services and assessed the association of use with sociodemographic and mobility characteristics by means of logistic regressions. RESULTS: A total of 6,991 participants were included in this analysis; 82.9% were Guatemalans living in Guatemala, 9.2% were Guatemalans living in Mexico, 7.8% were Mexicans living in Mexico, and 0.16% were Mexicans living in Guatemala. 2.6% of all participants reported having a health problem in the past two weeks, of whom 58.1% received care. Guatemalans living in Guatemala were the only group reporting cross-border use of health services. In multivariate analyses, Guatemalans living in Guatemala working in Mexico (compared to not working in Mexico) (OR 3.45; 95% CI 1.02,11.65), and working in agriculture/cattle, industry, or construction while in Mexico (compared to working in other sectors) (OR 26.67; 95% CI 1.97,360.85), were associated with cross-border use. CONCLUSIONS: Cross-border use of health services in this region is related to transborder work (i.e., circumstantial use of cross-border health services). This points to the importance of considering the health needs of migrant workers in Mexican health policies and developing strategies to facilitate and increase their access to health services.

Capacity building at points of entry during COVID-19 pandemic: harmonising training curriculum for Economic Community of West African States.

This paper describes the process for developing, validating and disseminating through a train-the-trainer (TOT) event a standardised curriculum for public health capacity building for points of entry (POE) staff across the 15-member state Economic Community of West African States (ECOWAS) that reflects both international standards and national guidelines.A five-phase process was used in developing the curriculum: phase (1) assessment of existing materials developed by the US Centers for Disease Control and Prevention (CDC), Africa CDC and the West African Economic and Monetary Union, (2) design of retained and new, harmonised content, (3) validation by the national leadership to produce final content, (4) implementation of the harmonised curriculum during a regional TOT, and (5) evaluation of the curriculum.Of the nine modules assessed in English and French, the technical team agreed to retain six harmonised modules providing materials for 10 days of intensive training. Following the TOT, most participants (n=28/30, 93.3%) indicated that the International Health Regulations and emergency management modules were relevant to their work and 96.7% (n=29/30) reported that the training should be cascaded to POE staff in their countries.The ECOWAS harmonised POE curriculum provides a set of training materials and expectations for national port health and POE staff to use across the region. This initiative contributes to reducing the effort required by countries to identify emergency preparedness and response capacity-building tools for border health systems in the Member States in a highly connected region.

Using spatial and population mobility models to inform outbreak response approaches in the Ebola affected area, Democratic Republic of the Congo, 2018-2020.

The Democratic Republic of the Congo's (DRC) 10th known Ebola virus disease (EVD) outbreak occurred between August 1, 2018 and June 25, 2020, and was the largest EVD outbreak in the country's history. During this outbreak, the DRC Ministry of Health initiated traveller health screening at points of control (POC, locations not on the border) and points of entry (POE) to minimize disease translocation via ground and air travel. We sought to develop a model-based approach that could be applied in future outbreaks to inform decisions for optimizing POC and POE placement, and allocation of resources more broadly, to mitigate the risk of disease translocation associated with ground-level population mobility. We applied a parameter-free mobility model, the radiation model, to estimate likelihood of ground travel between selected origin locations (including Beni, DRC) and surrounding population centres, based on population size and drive-time. We then performed a road network route analysis and included estimated population movement results to calculate the proportionate volume of travellers who would move along each road segment; this reflects the proportion of travellers that could be screened at a POC or POE. For Beni, the road segments estimated to have the highest proportion of travellers that could be screened were part of routes into Uganda and Rwanda. Conversely, road segments that were part of routes to other population centres within the DRC were estimated to have relatively lower proportions. We observed a posteriori that, in many instances, our results aligned with locations that were selected for actual POC or POE placement through more time-consuming methods. This study has demonstrated that mobility models and simple spatial techniques can help identify potential locations for health screening at newly placed POC or existing POE during public health emergencies based on expected movement patterns. Importantly, we have provided methods to estimate the proportionate volume of travellers that POC or POE screening measures would assess based on their location. This is critical information in outbreak situations when timely decisions must be made to implement public health interventions that reach the most individuals across a network.

Using Population Mobility Patterns to Adapt COVID-19 Response Strategies in 3 East Africa Countries.

The COVID-19 pandemic spread between neighboring countries through land, water, and air travel. Since May 2020, ministries of health for the Democratic Republic of the Congo, Tanzania, and Uganda have sought to clarify population movement patterns to improve their disease surveillance and pandemic response efforts. Ministry of Health-led teams completed focus group discussions with participatory mapping using country-adapted Population Connectivity Across Borders toolkits. They analyzed the qualitative and spatial data to prioritize locations for enhanced COVID-19 surveillance, community outreach, and cross-border collaboration. Each country employed varying toolkit strategies, but all countries applied the results to adapt their national and binational communicable disease response strategies during the pandemic, although the Democratic Republic of the Congo used only the raw data rather than generating datasets and digitized products. This 3-country comparison highlights how governments create preparedness and response strategies adapted to their unique sociocultural and cross-border dynamics to strengthen global health security.
