RESUMEN

CONTEXT: The COVID-19 pandemic highlighted the need for a well-trained public health workforce prior to the public health crisis. Public health training centers regularly assess workforce needs and their pre-pandemic data play vital roles in guiding public health workforce development beyond the crisis. PROGRAM: In 2019, Oklahoma partners of the Region 6 South Central Public Health Training Center (R6SCPHTC) co-conducted an online survey of the public health workforce located in the Health Resources & Services Administration Region 6. IMPLEMENTATION: Between March and April, the R6SCPHTC collected 503 surveys, including 201 surveys from Oklahoma. Questions inquired about demographic and workforce characteristics, work contexts, training needs and interests, training access and logistics, and knowledge of R6SCPHTC online resources. EVALUATION: Key findings included that two-thirds of the pre-pandemic Oklahoma public health workforce consisted of employees age 40 or older with few holding public health or medical degrees. The majority of respondents worked for health departments and Tribes, and almost half were frontline workers. Although at least half of the participants interested in training on public health activities and topics were familiar with them, confidence in their abilities related to these activities and topics was expressed by less than half. Qualitative data provided details on training needs addressed quantitatively and described new training areas. Survey participants expressed interest in diverse training delivery methods and technological devices. Most respondents were not familiar with the free trainings available through the R6SCPHTC. DISCUSSION: Similar to the regional and national public health workforce, Oklahoma's workforce needed training and support already before COVID-19. Time and resources need to be invested into the current and future workforce. While addressing priority public health skills and topics remains important, training on current and emerging topics is needed. Providing accessible trainings with expanded content will prepare Oklahoma's public health workforce for the future.

RESUMEN

CONTEXT: Community health workers (CHWs) are vital frontline public health workers. Given their trusted roles and connection to and understanding of the communities they serve, CHWs are able to link underserved communities to resources and public health agencies. With CHWs' increased prominence in the public health workforce, calls have been made for expanding and supporting CHW training and career development opportunities. PROGRAM: Public health training centers (PHTCs) are mandated to assess public health workforce needs, provide evidence-based professional development trainings, and increase students' aptitude for working with underserved and underresourced communities through applied practice experiences. Public health training centers can support CHWs in each of these areas. DESIGN: Case studies from 3 PHTCs are provided to exemplify how PHTCs are well positioned to support the critical CHW workforce via assessment, training, and student field placements. IMPLEMENTATION: A regional needs assessment survey with a designated section for CHWs, the provision of accessible and relevant CHW training, and CHW-focused student field placements were implemented in PHTC Regions 6/South Central, 1/New England, and 5/Great Lakes, respectively. EVALUATION: The Region 6 needs assessment found that CHWs in Oklahoma had multiple core roles and training interests. A crosswalk of needs and available training in the region guided the creation of tailored CHW trainings. Across 35 CHW-targeted trainings in Region 1, 88.5% of trainees were satisfied with the trainings and identified actions they could take to apply information they learned to their work. Significant improvements ( P < .001) in knowledge occurred across the 13 trainings that had pre-/posttests. In Region 5, students engaged with CHW-based organizations in Wisconsin to inform statewide CHW priority action items and deliverables and found the field placements meaningful for their academic experience. DISCUSSION: Public health training centers' strengths in workforce development can complement and extend existing efforts to support the CHW workforce.

RESUMEN

Background ­: The Region 6 South Central Public Health Training Center conducts needs assessments to inform the development of online trainings tailored to the HRSA Region 6 health and public health workforce. The purpose of this study was to assess Oklahoma's Community Health Representative (CHR) / Community Health Worker (CHW) workforce characteristics, current trainings, and training needs to guide the development of online trainings. Methods ­: This survey-based needs assessment for health and public health workforce training needs asked about alternative job titles, top three health issues addressed, roles played, skills used, current trainings, and training needs. Descriptive statistical analysis provided insights about CHRs/CHWs. The Fisher's exact test was used to compare frequency of responses between CHRs and CHWs, with p-values <0.05 considered significant. We analyzed qualitative data by using a modified content analysis. Results ­: Fifty-one self-identified CHRs/CHWs in Oklahoma participated in the 2019 regional health and public health training needs assessment. Most CHRs/CHWs were female and identified as "frontline public health workers." Respondents reported a range of educational attainment and diverse job titles. CHRs worked at tribal health or public health organizations primarily in rural areas. Most CHWs worked in urban areas and were employed by state and local health departments or community-based organizations. CHRs/CHWs had a broad spectrum of roles and skills, with required trainings reflecting various organizational needs. CHRs/CHWs expressed strong interest in receiving additional trainings via multiple delivery formats. Discussion and Conclusions ­: Oklahoma's CHRs/CHWs would benefit from and utilize workforce development, including trainings on a broad spectrum of roles and skills in multiple delivery formats. Potential employers and funders across the state would benefit from education on CHRs/CHWs as a workforce, team-integration, and sustainable funding.

RESUMEN

OBJECTIVE: Few studies have reported the outcome of direct outreach methods for recruitment of research participants in population-based samples. We describe the relationship of outreach strategies that are tailored to specific community factors to recruitment and consent outcomes in 10 National Children's Study direct outreach study locations (all were single counties). METHODS: Each study center collected data from a target population of women who resided in selected county segments that were sampled based on a geographic area probability sampling design. Based on county characteristics of the 10 study locations, each study center used site-specific marketing approaches (direct mail, mass media, provider referrals, social networking) to recruit study participants. Recruitment success was measured by the number of recruited women as well as by a qualitative assessment of the effectiveness of various recruitment methods. RESULTS: The number of women who consented varied from 67 to 792. The majority of women were pregnant at the time of consent. Community awareness varied from <1% to 70%. Although no significant associations were found between community characteristics and recruitment success, we found that certain types of outreach strategies enhanced recruitment. CONCLUSIONS: In a small sample of 10 US counties, recruitment success was not associated with community characteristics. It was, however, associated with certain types of outreach strategies that may be more effective in close-knit communities.

RESUMEN

The Environmental Public Health Tracking Network (EPHTN) proposes to link environmental hazards and exposures to health outcomes. Statistical methods used in case-control and cohort studies to link health outcomes to individual exposure estimates are well developed. However, reliable exposure estimates for many contaminants are not available at the individual level. In these cases, exposure/hazard data are often aggregated over a geographic area, and ecologic models are used to relate health outcome and exposure/hazard. Ecologic models are not without limitations in interpretation. EPHTN data are characteristic of much information currently being collected--they are multivariate, with many predictors and response variables, often aggregated over geographic regions (small and large) and correlated in space and/or time. The methods to model trends in space and time, handle correlation structures in the data, estimate effects, test hypotheses, and predict future outcomes are relatively new and without extensive application in environmental public health. In this article we outline a tiered approach to data analysis for EPHTN and review the use of standard methods for relating exposure/hazards, disease mapping and clustering techniques, Bayesian approaches, Markov chain Monte Carlo methods for estimation of posterior parameters, and geostatistical methods. The advantages and limitations of these methods are discussed.

RESUMEN

Public policy can be an effective method of promoting public health and preventing disease in a population. The proposing and passing of a municipal ordinance regulating power-sanding of leaded paint in New Orleans is a policy-level intervention that implements a primary prevention measure to address a community-wide risk. The process of achieving policy change involves defining the problem and the proposed intervention, integrating the resources of the individuals and groups with a stake in the situation, and disseminating information to the general public and to legislators. The implementation of the ordinance regulating power-sanding in New Orleans is a community-level lead poisoning prevention strategy.

RESUMEN

BACKGROUND: Exposure to lead hazards is a serious health concern for inner-city children. In the United States, the greatest contributor to an elevated lead level is lead exposure in the home. There are federal regulations to protect children in public housing developments from exposure to lead paint. The efficacy of these regulations has not been examined. METHODS: We assessed the association between residence in a public housing development and the risk of an elevated blood lead level among high-risk children in New Orleans. We did so by conducting a case-control study among 7121 children age 6 to 71 months who received a screening blood lead test from New Orleans public health clinics in 1998. RESULTS: We found elevated blood lead levels for 29% of children who were screened. Children residing in New Orleans housing developments had lead levels no different from those residing in nondevelopment housing when controlling for housing age, and child's sex and age (odds ratio = 0.93; 95% confidence interval = 0.77-1.1). CONCLUSIONS: Despite legislative efforts, public housing does not appear to protect children from elevated lead levels, calling into question the efficacy of existing regulations.
