Applying Data Analytics to Address Social Determinants of Health in Practice.

As public health and health care increase focus toward addressing social determinants of health (SDH), the growth of data and analytics affords new, impactful tools for data-informed community health improvement. Best practices should be established for responsible use, meaningful interpretation, and actionable implementation of SDH data for community health improvement.

Incident Tick-Borne Infections in a Cohort of North Carolina Outdoor Workers.

Tick-borne diseases cause substantial morbidity throughout the United States, and North Carolina has a high incidence of spotted fever rickettsioses and ehrlichiosis, with sporadic cases of Lyme disease. The occupational risk of tick-borne infections among outdoor workers is high, particularly those working on publicly managed lands. This study identified incident tick-borne infections and examined seroconversion risk factors among a cohort of North Carolina outdoor workers. Workers from the North Carolina State Divisions of Forestry, Parks and Recreation, and Wildlife (n = 159) were followed for 2 years in a randomized controlled trial evaluating the effectiveness of long-lasting permethrin-impregnated clothing. Antibody titers against Rickettsia parkeri, Rickettsia rickettsii, "Rickettsia amblyommii," and Ehrlichia chaffeensis were measured at baseline (n = 130), after 1 year (n = 82), and after 2 years (n = 73). Titers against Borrelia burgdorferi were measured at baseline and after 2 years (n = 90). Baseline seroprevalence, defined as indirect immunofluorescence antibody titers of 1/128 or greater, was R. parkeri (24%), R. rickettsii (19%), "R. amblyommii" (12%), and E. chaffeensis (4%). Incident infection was defined as a fourfold increase in titer over a 1-year period. There were 40 total seroconversions to at least one pathogen, including R. parkeri (n = 19), "R. amblyommii" (n = 14), R. rickettsii (n = 9), and E. chaffeensis (n = 8). There were no subjects whose sera were reactive to B. burgdorferi C6 antigen. Thirty-eight of the 40 incident infections were subclinical. The overall risk of infection by any pathogen during the study period was 0.26, and the risk among the NC Division of Forest Resources workers was 1.73 times that of workers in other divisions (95% confidence interval [CI]: 1.02, 2.92). The risk of infection was lower in subjects wearing permethrin-impregnated clothing, but not significantly (risk ratio = 0.81; 95% CI: 0.47, 1.39). In summary, outdoor workers in North Carolina are at high risk of incident tick-borne infections, most of which appear to be asymptomatic.

Partnering to meet training needs: a communicable-disease continuing education course for public health nurses in North Carolina.

In 2004, the General Communicable Disease Control Branch of the North Carolina Division of Public Health and the North Carolina Center for Public Health Preparedness partnered to create a free continuing education course in communicable-disease surveillance and outbreak investigations for public health nurses. The course was a competency-based curriculum with 14 weeks of Internet-based instruction, culminating in a two-day classroom-based skills demonstration. In spring 2006, the course became mandatory for all public health nurses who spend at least three-fourths of their time on tasks related to communicable diseases. As of December 2006, 177 nurses specializing in communicable diseases from 74 North Carolina counties had completed the course. Evaluations indicated that participants showed statistically significant improvements in self-perceived confidence to perform competencies addressed by the course. This course has become a successful model that combines academic expertise in curriculum development and teaching technologies with practical expertise in course content and audience needs. Through a combination of Internet and classroom instruction, this course has delivered competency-based training to the public health professionals who perform as frontline epidemiologists throughout North Carolina.
