Training Needs and Awareness of Emerging Areas of Public Health Practice Among Epidemiologists Working in State Health Agency Central Offices in the United States, 2017.

CONTEXT: Epidemiologists working in state health agency central offices (SHA-CO) are key professionals working to monitor population health indicators. Assessing training needs to identify gaps is critical to ensuring a competent public health workforce. OBJECTIVE: The objective of this research was to identify training needs of SHA-CO epidemiologists and their awareness of emerging areas of public health practice (EAoP) using data from the 2017 Public Health Workforce Interests and Needs Survey (PH WINS). DESIGN: SHA-CO epidemiologists were surveyed in fall 2017 using a Web-based tool. Balanced repeated replication weights were used to account for complex sample design. Differences in responses by tenure, education level, and supervisory status were assessed using multinomial logistic regression. SETTING: Forty-seven state health agencies. PARTICIPANTS: Permanently employed SHA-CO epidemiologists. MAIN OUTCOME MEASURES: Training needs were identified by classifying skill gaps as those skills that participants self-reported as high relevance to day-to-day work but self-rated as having low proficiency. Awareness of EAoP was self-reported. RESULTS: Systems and strategic thinking and budget and financial management were the areas with the greatest training needs. For most skill domains, fewer participants reported skill gaps with increasing years of public health work experience. Participants with 16 or more years of work experience were less likely to be motivated by most training motivators listed by epidemiologists with 5 or fewer years of experience. The EAoP participants reported greatest awareness of evidence-based public health practice (67%), and the EAoP they reported hearing least about was Health in All Policies (14%). CONCLUSIONS: Stratified analyses by tenure identified important differences in training needs and motivators that employers can use to customize workforce development strategies. SHA-CO epidemiologists reported varying amounts of awareness of EAoP. Specialized training approaches may contribute to improved employee engagement and reduce skill gaps among SHA-CO epidemiologists.

Assessment of Epidemiology Capacity in State Health Departments - United States, 2017.

In 2017, the Council of State and Territorial Epidemiologists performed its sixth periodic Epidemiology Capacity Assessment, a national assessment that evaluates trends in workforce size, funding, and epidemiology capacity among state health departments. A standardized web-based questionnaire was sent to the state epidemiologist in the 50 states, the District of Columbia (DC), and the U.S. territories and the Federated States of Micronesia inquiring about the number of current and optimal epidemiologist positions; sources of epidemiology activity and personnel funding; and each department's self-perceived capacity to lead activities, provide subject matter expertise, and obtain and manage resources for the four Essential Public Health Services (EPHS)* most closely linked to epidemiology. From 2013 to 2017, the number of state health department epidemiologists† increased 22%, from 2,752 to 3,369, the greatest number of workers since the first full Epidemiology Capacity Assessment enumeration in 2004. The federal government provided most (77%) of the funding for epidemiologic activities and personnel. Substantial to full capacity (50%-100%) was highest for investigating health problems (92% of health departments) and monitoring health status (84%), whereas capacity for evaluating effectiveness (39%) and applied research (29%) was considerably lower. An estimated additional 1,200 epidemiologists are needed to reach full capacity to conduct the four EPHS. Additional resources might be needed to ensure that state health department epidemiologists possess the specialized skills to deliver EPHS, particularly in evaluation and applied epidemiologic research.

Per- and polyfluoroalkyl substance (PFAS) exposure assessment in a community exposed to contaminated drinking water, New Hampshire, 2015.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals used in manufacturing that resist environmental degradation, can leach into drinking water, and bioaccumulate in tissues. Some studies have shown associations with negative health outcomes. In May 2014, a New Hampshire public drinking water supply was found to be contaminated with PFAS from a former U.S. Air Force base. OBJECTIVES: We established a serum testing program to assess PFAS exposure in the affected community. METHODS: Serum samples and demographic and exposure information were collected from consenting eligible participants. Samples were tested for PFAS at three analytical laboratories. Geometric means and 95% confidence intervals were calculated and analyzed by age and exposure variables. RESULTS: A total of 1578 individuals provided samples for PFAS testing; >94% were found to have perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorohexane sulfonic acid (PFHxS) detectable in serum. Geometric mean serum concentrations of PFOS, PFOA, and PFHxS were 8.6 µg/L (95% CI:8.3-8.9), 3.1 µg/L (95% CI: 3.0-3.2), and 4.1 µg/L (95% CI: 3.9-4.3), respectively, which were statistically higher than the general U.S. POPULATION: Significant associations were observed between PFAS serum concentrations and age, time spent in the affected community, childcare attendance, and water consumption. CONCLUSIONS: PFOS, PFOA, and PFHxS were found in significantly higher levels in the affected population, consistent with PFAS drinking water contamination. Given increased recognition of PFAS contamination in the U.S, a coordinated national response is needed to improve access to biomonitoring and understand health impacts.
