Exposure Matters: Examining The Physical And Psychological Health Impacts Of Toxic Contamination Using Gis And Survey Data

In the late 1970s and early 1980s, the grassroots environmental movement brought national attention to the issues related to inequities in environmental quality. Previous research addressing these environmental inequities has progressively increased and advanced methodologically. However, the arguments and focus have been primarily limited to examining the socio-demographics in an ongoing debate of race and class. This thesis extends past the methodological stalemate focusing on the application of Geographic Information Systems (GIS) using survey data in an environmental justice case study of a community in south Florida. This approach examines the social, health and environmental impacts of a Superfund site on a low income, minority community. Using geo-coded survey (N=223) and environmental data (ash deposition patterns), this thesis employs path analysis to test the hypothesis that exposure matters. The exposure matters hypothesis suggests exposure (perceived, self-reported and actual) is a significant predictor of physical and psychological health. Results discuss significant findings, and then compare them with previous disaster and trauma-related research and present directions for future research

Measuring Changes in Local Surveillance and Investigation Capacity

Background: The outbreak of Ebola virus disease in West Africa and confirmation of the first cases in the United States highlight the need for robust and responsive public health surveillance system. With a 25% decline in funding since 2007, the impact on local surveillance capacities has not previously been described. Purpose: The Surveillance & Investigation domain of the Local Health Department Preparedness Capacities Survey (PCAS) was reweighted to reflect the national profile of LHDs. Changes in subdomain performance of capacities and the effect of population size on subdomain capacity performance were examined over time. Methods: Participating LHDs (n=208) from the PCAS sample were reweighted according to characteristics from the 2010 National Association of County and City Health Officials (NACCHO) Profile. Overall changes in preparedness capacity across four subdomains from 2010 to 2012 were tested for significant differences using a weighted t-test. A series of weighted least squares regression models were used to determine whether population size may have modified the temporal changes in preparedness capacity. Results: Significant declines were observed in the preparedness capacity in three of the four subdomains of Surveillance & Investigation. Results suggest that surveillance inputs from various sources, including hospitals, urgent care, poison control, pharmacies, and schools absentee reporting, especially for larger LHDs, may be more sensitive to changes or shifts over time versus others. Implications: Declines in preparedness capacity may have affected the ability of LHDs, particularly larger ones, to effectively respond to community preparedness needs and, specifically, the detection of highly communicable and novel disease events

Temporal Trends in Local Public Health Preparedness Capacity

Local health departments (LHDs) are essential to emergency preparedness and response activities. Since 2005, LHD resources for preparedness, including personnel, are declining in the face of continuing gaps and variation in the performance of preparedness activities. The effect of these funding decreases on LHD preparedness performance is not well understood. This study examines the performance of preparedness capacities among NC LHDs and a matched national comparison group of LHDs over three years. We observe significant decreases in five of eight preparedness domains from three years of survey data collected from 2010 through 2012. Most notably, we observe significant decreases in the Surveillance & Investigation domain. Performance decreases may be a result of continued, compounding declines in preparedness funding

Evaluating Use of Custom Survey Reports by Local Health Departments

This report demonstrates how providing survey feedback, like comparative reports, to survey respondents can result in improvement activities. For each of the past three years (2010-2013), the North Carolina Institute for Public Health (NCIPH) has invited local health departments (LHDs) from 40 states to participate in a preparedness capacities survey. In addition, NCIPH fielded a six-question evaluation survey to a subset of LHDs (n=70) to determine how LHDs use these reports. LHDs that reported using their custom reports compared their preparedness capacities to other LHDs, conducted strategic planning (e.g., benchmarking, setting preparedness goals), planned staff trainings, and disseminated the report both internally and to external preparedness partners. Through evaluation of custom report use, we have found that survey feedback is a valuable part of a participatory research approach that promotes and encourages discussion, motivates improvement, and provides opportunities to identify potential solutions relevant to both researchers and LHDs

New Perspectives on the “Silo Effect” – Initial Comparisons of Network Structures across Public Health Collaboratives

Objectives: We explored to what extent "silos" (preferential partnering) persist in interorganizational boundaries despite advances in working across boundaries. We focused on organizational homophily and resulting silo effects within networks that might both facilitate and impede success in public health collaboratives (PHCs). Methods: We analyzed data from 162 PHCs with a series of exponential random graph models to determine the influence of uniform and differential homophily among organizations and to identify the propensity for partnerships with similar organizations. Results: The results demonstrated a low presence (8%) of uniform homophily among networks, whereas a greater number (30%) of PHCs contained varying levels of differential homophily by 1 or more types of organization. We noted that the higher frequency among law enforcement, nonprofits, and public health organizations demonstrated a partner preference with similar organizations. Conclusions: Although we identified only a modest occurrence of partner preference in PHCs, overall success in efforts to work across boundaries might be problematic when public health members (often leaders of PHCs) exhibit the tendency to form silos

Effects of Performance Improvement Programs on Preparedness Capacities

In response to public health systems and services research priorities, we examined the extent to which participation in accreditation and performance improvement programs can be expected to enhance preparedness capacities

Integration opportunities for HIV and family planning services in Addis Ababa, Ethiopia: an organizational network analysis

Abstract Background Public health resources are often deployed in developing countries by foreign governments, national governments, civil society and the private health clinics, but seldom in ways that are coordinated within a particular community or population. The lack of coordination results in inefficiencies and suboptimal results. Organizational network analysis can reveal how organizations interact with each other and provide insights into means of realizing better public health results from the resources already deployed. Our objective in this study was to identify the missed opportunities for the integration of HIV care and family planning services and to inform future network strengthening. Methods In two sub-cities of Addis Ababa, we identified each organization providing either HIV care or family planning services. We interviewed representatives of each of them about exchanges of clients with each of the others. With network analysis, we identified network characteristics in each sub-city network, such as referral density and centrality; and gaps in the referral patterns. The results were shared with representatives from the organizations. Results The two networks were of similar size (25 and 26 organizations) and had referral densities of 0.115 and 0.155 out of a possible range from 0 (none) to 1.0 (all possible connections). Two organizations in one sub-city did not refer HIV clients to a family planning organization. One organization in one sub-city and seven in the other offered few HIV services and did not refer clients to any other HIV service provider. Representatives from the networks confirmed the results reflected their experience and expressed an interest in establishing more links between organizations. Conclusions Because of organizations not working together, women in the two sub-cities were at risk of not receiving needed family planning or HIV care services. Facilitating referrals among a few organizations that are most often working in isolation could remediate the problem, but the overall referral densities suggests that improved connections throughout might benefit conditions in addition to HIV and family planning that need service integration

Institutional Facilitators and Barriers to Local Public Health Preparedness Planning for Vulnerable and At-Risk Populations

Numerous institutional facilitators and barriers to preparedness planning exist at the local level for vulnerable and at-risk populations. Findings of this evaluation study contribute to ongoing practice-based efforts to improve response services and address public health preparedness planning and training as they relate to vulnerable and at-risk populations
