The Solutions in Health Analytics for Rural Equity Across the Northwest (SHARE-NW) Dashboard for Health Equity in Rural Public Health: Usability Evaluation

BACKGROUND

Given the dearth of resources to support rural public health practice, the solutions in health analytics for rural equity across the northwest dashboard (SHAREdash) was created to support rural county public health departments in northwestern United States with accessible and relevant data to identify and address health disparities in their jurisdictions. To ensure the development of useful dashboards, assessment of usability should occur at multiple stages throughout the system development life cycle. SHAREdash was refined via user-centered design methods, and upon completion, it is critical to evaluate the usability of SHAREdash.

OBJECTIVE

This study aims to evaluate the usability of SHAREdash based on the system development lifecycle stage 3 evaluation goals of efficiency, satisfaction, and validity.

METHODS

Public health professionals from rural health departments from Washington, Idaho, Oregon, and Alaska were enrolled in the usability study from January to April 2022. The web-based evaluation consisted of 2 think-aloud tasks and a semistructured qualitative interview. Think-aloud tasks assessed efficiency and effectiveness, and the interview investigated satisfaction and overall usability. Verbatim transcripts from the tasks and interviews were analyzed using directed content analysis.

RESULTS

Of the 9 participants, all were female and most worked at a local health department (7/9, 78%). A mean of 10.1 (SD 1.4) clicks for task 1 (could be completed in 7 clicks) and 11.4 (SD 2.0) clicks for task 2 (could be completed in 9 clicks) were recorded. For both tasks, most participants required no prompting-89% (n=8) participants for task 1 and 67% (n=6) participants for task 2, respectively. For effectiveness, all participants were able to complete each task accurately and comprehensively. Overall, the participants were highly satisfied with the dashboard with everyone remarking on the utility of using it to support their work, particularly to compare their jurisdiction to others. Finally, half of the participants stated that the ability to share the graphs from the dashboard would be "extremely useful" for their work. The only aspect of the dashboard cited as problematic is the amount of missing data that was present, which was a constraint of the data available about rural jurisdictions.

CONCLUSIONS

Think-aloud tasks showed that the SHAREdash allows users to complete tasks efficiently. Overall, participants reported being very satisfied with the dashboard and provided multiple ways they planned to use it to support their work. The main usability issue identified was the lack of available data indicating the importance of addressing the ongoing issues of missing and fragmented public health data, particularly for rural communities.

Local Health Department Engagement in Access to Mental Health Services and Mental Health Policy or Advocacy Activities

CONTEXT

Mental health is a public health concern that requires national attention at the local level. Major issues facing local health departments (LHDs) to actively engage in mental health activities include inadequate surveillance data and limited resources.

OBJECTIVE

To examine the levels of engagement in access to mental health services, as well as policy or advocacy activities, by LHDs characteristics.

DESIGN

The study design is cross-sectional based on the national survey of LHDs. We analyzed the survey data from the National Association of County and City Health Officials' 2019 Profile study. Logistic regression was performed with 6 levels of engagement in mental health activities as the outcome measures.

RESULTS

LHDs reported that a majority had assessed the gaps in access to mental health (57.69%), followed by other activities-had implemented strategies to increase access to mental health (48.77%), implemented strategies to target underserved populations (40.66%), evaluated strategies to target underserved populations (38.84%), engaged in policy/advocacy to address mental health (32.27%), and finally addressed gaps through provision of mental health (22.31%). LHDs' governance structure was strongly associated with engagement in all 6 mental health activities. LHDs that had performed improvement processes, had behavioral health staff, and had cross-jurisdictional sharing were more likely to be engaged in all 6 of the mental health activities. LHDs were also more likely to be engaged in 5 of the 6 mental health activities if they had some relationships with faith communities and in 4 of the 6 mental health activities if they had some relationships with community health centers.

CONCLUSIONS

Levels of engagement in mental health policy or advocacy activities among LHDs were low and varied by LHD characteristics. Intervention strategies may include encouraging LHDs to actively engage in mental health activities, participating in Public Health Accreditation Board accreditation program, and incentivizing mental health workforce retention.

Dance of Dollars: State Funding Effects on Local Health Department Expenditures

OBJECTIVE

We examined changes in total local health department (LHD) expenditures in the state of Washington following introduction of a new state funding program to support core public health services and infrastructure.

METHODS

We used a pre/posttest design regression model to evaluate changes in LHD expenditures 1, 2, and 6 years into the new state program. To address potential endogeneity in the model, we repeated all 3 analyses using 2-stage least squares regression.

RESULTS

In the base case, overall spending among LHDs significantly increased with receipt of the new state funds in the first years of the program (2008 and 2009). However, those increases were not sustained over the longer term (2013). In subpopulation analyses, total LHD spending increased more among larger LHDs.

CONCLUSIONS

Between 2006 and 2013, new state investments in core public health functions increased Washington State LHD expenditures in the short term, but those increases did not persist over time. For public health financial modernization efforts to translate into public health infrastructure modernization successes, the way new investments are structured may be as important as the amount of funding added.

An Analysis of How Characteristics of Local Health Department Jurisdictions Influence Involvement in PHAB Accreditation: Implications for Health Equity

OBJECTIVE

To explore how characteristics of local health department (LHD) jurisdictions impact involvement in Public Health Accreditation Board (PHAB) accreditation and to characterize the implications for health equity.

METHODS

Data from the 2016 National Profile of LHDs survey were linked with data from the American Community Survey, National Center for Health Statistics, Behavioral Risk Factor Surveillance System, and the 2016 presidential election. Outcome measures included LHDs that were formally engaged in PHAB accreditation and LHDs that planned to apply for PHAB accreditation but were not formally engaged. Logistic regression was used to assess for the impact LHD jurisdictions' socioeconomic position, demographics, population health status, political ideology, and LHD organizational characteristics have on PHAB accreditation.

RESULTS

Approximately 37% of the participants were formally engaged (n = 297) and planned to apply (n = 337) for PHAB accreditation. Involvement in PHAB accreditation was equal among LHDs based on poverty and income inequality, but median household income was negatively associated. Diverse jurisdictions were more likely to be involved in PHAB accreditation but less likely to be involved after controlling for covariates. Jurisdictions with worse population health status were either as likely or more likely to be involved in PHAB accreditation. Jurisdictions with a greater conservative political ideology were less likely to be involved.

CONCLUSION

LHD involvement in PHAB accreditation varies by their jurisdiction's characteristics. This has implications for health equity based on socioeconomic, racial, and population health status. Policies and practices are needed to improve the uptake of PHAB accreditation in LHD jurisdictions impacted most by health inequities.

Leveraging Limited Resources Through Cross-Jurisdictional Sharing: Influences on Breastfeeding Rates

BACKGROUND

Cross-jurisdictional sharing is gaining traction as an option for increasing the effectiveness and efficiency of public health services in local health departments.

RESEARCH AIM

Assess whether breastfeeding initiation among participants in the Special Supplemental Nutrition Program for Women, Infants and Children changed with the addition of a trained breastfeeding specialist funded by cross-jurisdictional integration.

METHODS

A longitudinal retrospective comparative difference in difference design using state-based program data, pre- and post-integration was undertaken. Three local county health departments (n = 5) that fully integrated into one Community Health Board during January 2015, and four neighboring Community Health Boards (n = 4) that did not integrate, were included.

RESULTS

Controlling for confounders and interactions, the relative rate of change over time in breastfeeding initiation rates was greater in the integrated jurisdiction than neighboring Community Health Boards, but not statistically significant. When the integrated Community Health Board's original three local health departments were considered separately, the relative rate of change over time in breastfeeding rates was greater for one local health department in comparison to three neighbor Community Health Boards (p = .037, .048, and .034, respectively).

CONCLUSIONS

The addition of a specialized breastfeeding nutritionist led to improved breastfeeding initiation rates. The increase was significant only in the largest original local health department, which also had the lowest breastfeeding initiation rate pre-merger. The greatest positive change was seen in this local health department where the specialist staff was physically located. Public health staff specialization can lead to increases in economic efficiency and in improved delivery of public health services.

Local Health Departments' Engagement in Activities to Address Opioid Use and Abuse: The Influence of Surveillance Systems' Use

AIMS

To examine the extent to which local health departments (LHDs) conduct activities to address opioid use and abuse. To test the hypothesis that (i) LHDs' access to data from an electronic syndromic surveillance system is associated with conducting activities to address opioid use and abuse, and (ii) among those LHDs with access to syndromic surveillance data, the use of syndromic and other surveillance data on opioid-related events is associated with LHDs' report of conducting activities to address opioid use and abuse.

METHODS

Logistic regression was used to analyze data from the 2018 Forces of Change Survey of a statistically representative sample of 966 LHDs, of which 591 participated in the survey.

RESULTS

The LHDs' access to a syndromic surveillance system was significantly associated with their report of conducting activities to address opioid use and abuse. Compared with LHDs that had no surveillance systems, odds of participating in activities to address the opioid use or abuse were higher for LHDs that managed their own surveillance systems (adjusted odds ratio, AOR = 3.022, P = .03) and those who had but did not manage their own surveillance systems (AOR = 1.920, P < .01). The LHDs' use of syndromic surveillance systems (AOR = 2.98, P = .01) or other surveillance systems (AOR = 2.21, P = .03) was also associated with higher odds to participate in activities to address the opioid use or abuse (vs no such use).

CONCLUSION

The LHDs are strategically well positioned to play their role in addressing this multifaceted epidemic. Access to data or information from electronic syndromic surveillance systems that use hospital emergency department data might significantly improve LHDs' engagement in conducting activities to address opioid use and abuse within their communities while building their capacity to face the next epidemic.

Scale Effects and Expected Savings from Consolidation Policies of Italian Local Healthcare Authorities

BACKGROUND

Consolidation is often considered by policymakers as a means to reduce service delivery costs and enhance accountability.

OBJECTIVE

The aim of this study was to estimate the potential cost savings that may be derived from consolidation of local health authorities (LHAs) with specific reference to the Italian setting.

METHODS

For our empirical analysis, we use data relating to the costs of the LHAs as reported in the 2012 LHAs' Income Statements published within the New Health Information System (NSIS) by the Ministry of Health. With respect to the previous literature on the consolidation of local health departments (LHDs), which is based on ex-post-assessments on what has been the impact of the consolidation of LHDs on health spending, we use an ex-ante-evaluation design and simulate the potential cost savings that may arise from the consolidation of LHAs.

RESULTS

Our results show the existence of economies of scale with reference to a particular subset of the production costs of LHAs, i.e. administrative costs together with the purchasing costs of goods (such as drugs and medical devices) as well as non-healthcare-related services.

CONCLUSIONS

The research findings of our paper provide practical insight into the concerns and challenges of LHA consolidations and may have important implications for NHS organisation and for the containment of public healthcare expenditure.

Too Big, Too Small, or Just Right? Cost-Efficiency of Environmental Inspection Services in Connecticut

OBJECTIVE

To assess optimal activity size/mix of Connecticut local public health jurisdictions, through estimating economies of scale/scope/specialization for environmental inspections/services.

DATA SOURCES/STUDY SETTING

Connecticut's 74 local health jurisdictions (LHJs) must provide environmental health services, but their efficiency or reasons for wide cost variation are unknown. The public health system is decentralized, with variation in organizational structure/size. We develop/compile a longitudinal dataset covering all 74 LHJs, annually from 2005 to 2012.

STUDY DESIGN

We estimate a public health services/inspections cost function, where inputs are translated into outputs. We consider separate estimates of economies of scale/scope/specialization for four mandated inspection types.

DATA COLLECTION/EXTRACTION METHODS

We obtain data from Connecticut Department of Public Health databases, reports, and other publicly available sources. There has been no known previous utilization of this combined dataset.

PRINCIPAL FINDINGS

On average, regional districts, municipal departments, and part-time LHJs are performing fewer than the efficient number of inspections. The full-time municipal departments and regional districts are more efficient but still not at the minimum efficient scale. The regional districts' elasticities of scale are larger, implying they are more efficient than municipal health departments.

CONCLUSIONS

Local health jurisdictions may enhance efficiency by increasing inspections and/or sharing some services.

Investigating Informatics Activity, Control, and Training Needs in Large, Medium, and Small Health Departments

This article investigates informatics training needs in local health departments of different jurisdictional sizes.

A recent National Association of City & County Health Officials survey shed light on informatics workforce development needs. Local health departments (LHDs) of various jurisdictional sizes and control over informatics may differ on training needs and activity. Understanding the precise nature of this variation will allow stakeholders to appropriately develop workforce development tools to advance the field.

Characteristics of Local Health Departments Associated with Implementation of Electronic Health Records and Other Informatics Systems

OBJECTIVE

Assessing local health departments' (LHDs') informatics capacities is important, especially within the context of broader, systems-level health reform. We assessed a nationally representative sample of LHDs' adoption of information systems and the factors associated with adoption and implementation by examining electronic health records, health information exchange, immunization registry, electronic disease reporting system, and electronic laboratory reporting.

METHODS

We used data from the National Association of County and City Health Officials' 2013 National Profile of LHDs. We performed descriptive statistics and multinomial logistic regression for the five implementation-oriented outcome variables of interest, with three levels of implementation (implemented, plan to implement, and no activity). Independent variables included infrastructural and financial capacity and other characteristics associated with informatics capacity.

RESULTS

Of 505 LHDs that responded to the survey, 69 (13.5%) had implemented health information exchanges, 122 (22.2%) had implemented electronic health records, 245 (47.5%) had implemented electronic laboratory reporting, 368 (73.0%) had implemented an electronic disease reporting system, and 416 (83.8%) had implemented an immunization registry. LHD characteristics associated with health informatics adoption included provision of greater number of clinical services, greater per capita public health expenditures, health information systems specialists on staff, larger population size, decentralized governance system, one or more local boards of health, metropolitan jurisdiction, and top executive with more years in the job.

CONCLUSION

Many LHDs lack health informatics capacity, particularly in smaller, rural jurisdictions. Cross-jurisdictional sharing, investment in public health informatics infrastructure, and additional training may help address these shortfalls.

Local Health Departments' Activities to Address Health Disparities and Inequities: Are We Moving in the Right Direction?

Context: Health disparities are among the critical public health challenges. Objectives: To analyze the extent to which local health departments (LHDs) perform activities for addressing health disparities, changes in proportion of LHDs’ performing those activities since 2005, and factors associated with variation in such engagement. Methods: We used the 2013 National Profile of LHDs Survey to perform Logistic Regression of activities LHDs performed to address health disparities. Results: About 20 percent of LHDs did not perform any activity to address health disparities. Significant decreases occurred since 2005 in the proportion of LHDs that performed health disparity reduction/elimination activities for four activities. LHD characteristics significantly associated (p≤0.05) with the increased likelihood of performing activities to address health disparities were: recent completion of community health assessment, community health improvement plan and agency wide strategic plan. Other significant positive impacts on such activities included per capita expenditures, local governance, having one or more local boards of health, larger population size and metropolitan status of the LHD jurisdiction. Conclusions: Reduced infrastructural capacity of LHDs has resulted in fewer LHDs addressing health disparities in their jurisdictions. LHD characteristics associated with higher performance of activities for health disparity reduction identified by this research have important policy implications.

The impacts of local health department consolidation on public health expenditures: evidence from Ohio

We examined the effects of local health department (LHD) consolidations on the total and administrative expenditures of LHDs in Ohio from 2001 to 2011. We obtained data from annual records maintained by the state of Ohio and through interviews conducted with senior local health officials and identified 20 consolidations of LHDs occurring in Ohio in this time period. We found that consolidating LHDs experienced a reduction in total expenditures of approximately 16% (P = .017), although we found no statistically significant change in administrative expenses. County health officials who were interviewed concurred that their consolidations yielded financial benefits, and they also asserted that their consolidations yielded public health service improvements.

Economies of scale in the production of public health services: an analysis of local health districts in Florida

OBJECTIVES

We examined the existence and the extent of scale and scope economies in the delivery of public health services. We also tested the strength of agency, population, and community characteristics that moderate scale and scope economies.

METHODS

We collected service count and cost data for all Florida local health districts for 2008 and 2010, complemented with data on agency, population, and community characteristics. Using translog cost functions, we built models of operating efficiencies for 5 core public health activities: communicable disease surveillance, chronic disease prevention, food hygiene, on-site sewage treatment, and vital records.

RESULTS

Economies of scale were found in most activities, with cost per unit decreasing as volume increased. The models did not, however, identify meaningful economies of scope.

CONCLUSIONS

Consolidation or regionalization might lower cost per unit for select public health activities. This could free up resources for use in other areas, further improving the public's health.

Laying the groundwork for evidence-based public health: why some local health departments use more evidence-based decision-making practices than others

We examined variation in the use of evidence-based decision-making (EBDM) practices across local health departments (LHDs) in the United States and the extent to which this variation was predicted by resources, personnel, and governance. We analyzed data from the National Association of County and City Health Officials Profile of Local Health Departments, the Association of State and Territorial Health Officials State Health Departments Profile, and the US Census using 2-level multilevel regression models. We found more workforce predictors than resource predictors. Thus, although resources are related to LHDs' use of EBDM practices, the way resources are used (e.g., the types and qualifications of personnel hired) may be more important.

Linking costs to health outcomes for allocating scarce public health resources

Introduction:

Resources for public health (PH) are scarce and policymakers face tough decisions in determining their funding priorities. The difficulty of making these decisions is compounded by current PH accounting systems, which are ill-equipped to link fiscal resources to PH outcomes. This paper examines the types of revenues and expenditures, health services, and health outcomes that are being tracked at the local and state PH levels. The authors provide recommendations for strengthening the ability of local and state governments to link expenditures to PH outcomes, both within and across jurisdictions.

Framework and Next Steps:

The source of revenue data for most local jurisdictions is the accounting systems used for the budgeting and auditing of fiscal activities, and these are primarily linked to specific PH programs. In contrast, expenditure data are mostly generic and typically span multiple PH programs with no link to specific PH activities. Many challenges exist to then link PH activities to health outcomes data, which are often collected through separate reporting systems at the local, state, and national levels. Policy change at the state level and implementation strategies that are standardized across local health departments are required to assess the costs and health outcomes of PH activities.

Conclusion:

Information linking PH expenditures to health outcomes of PH services could greatly inform the decision-making process. This information will allow investments in PH to be better understood and will provide a strong foundation for the PH services and systems research community to understand variation and drive improvement. Ultimately, these data could be used to improve accountability at the local and state PH department levels.

Local health departments and the 2008 recession: characteristics of resiliency

BACKGROUND

The 2008 recession had a significant impact on local health departments (LHDs), with more than half of such agencies experiencing job losses and program cuts.

PURPOSE

To identify potential modifiable factors that can protect LHDs from job losses and budget cuts during future economic crises.

METHODS

This retrospective cohort study used data from 2005 and 2010 surveys of LHDs. The outcome of interest was financial resiliency for maintaining budgets during the recession and was based on the ratio of observed to predicted expenditures (O/E) per capita for 2010. Logistic regression was used to model the resiliency of the LHD with independent variables grouped around domains of organization, revenues, and services, with stratification by size of the LHD jurisdiction. Data were analyzed in 2013.

RESULTS

Of the 987 LHDs in the final data set, 328 (33.2%) were categorized as resilient and 659 (66.8%) as non-resilient. Overall, resilient LHDs received a higher percentage of revenues from non-local sources compared to non-resilient LHDs (p<0.05) and had a more diversified service mix, with significantly (p<0.05) more treatment, population, and regulatory services. In the final regression models, findings differed substantially across the stratifications of LHD jurisdictional population size, with no single independent or control variable significantly associated with resiliency across all population categories.

CONCLUSIONS

Funding streams and service mix may be modifiable characteristics, suggesting possible means for LHDs to weather future economic stress; however, these characteristics may be unique to the size of the population served.

Health districts as quality improvement collaboratives and multijurisdictional entities

CONTEXT

Local health departments are increasingly challenged to meet emerging health problems at the same time that they are being challenged with dwindling resources and the demands of accreditation.

OBJECTIVE

To assess the capacity of Multicounty health districts to serve as "Quality Improvement Collaboratives" and support local health departments to meet accreditation standards.

DESIGN

The study used an online survey tool and follow-up phone calls with key informants in health districts and county health departments in Georgia. Data collection was primarily based on an instrument to measure Quality Improvement Collaboratives that was adapted and tested for use with public health agencies in Georgia.

SETTING

The Georgia PBRN conducted this study of health districts and county health departments. The Georgia Department of Public Health supports 18 health districts and 159 county health departments (GA DPH, 2011). The health districts range in county composition from 1 to 16 counties in each district.

PARTICIPANTS

Key informants comprised district and county health department staff and county health department board members were identified by 13 participating health district offices.

RESULTS

Key opinion leaders from both the rural and nonrural counties agreed that the Districts were important for providing essential services and supporting quality improvement collaboration. Psychometric testing of the Quality Improvement Collaborative assessment public health instrument yielded high scores for validity and reliability.

CONCLUSIONS AND IMPLICATIONS

Regionalization of local public health capacity is a critical emerging issue for public health accreditation and quality improvement. This study demonstrated the utility of regionalization across traditional local geopolitical boundaries.

Public health services and systems research: current state of finance research

There is a growing recognition that the US public health system should strive for efficiency-that it should determine the optimal ways to utilize limited resources to improve and protect public health. The field of public health finance research is a critical part of efforts to understand the most efficient ways to use resources. This article discusses the current state of public health finance research through a review of public health finance literature, chronicles important lessons learned from public health finance research to date, discusses the challenges faced by those seeking to conduct financial research on the public health system, and discusses the role of public health finance research in relation to the broader endeavor of Public Health Services and Systems Research.

Diffusion of practice-based research in local public health: what differentiates adopters from nonadopters?

OBJECTIVE

To examine the level of involvement by local health departments (LHDs) in practice-based research (PBR) activities, and determine factors associated with variation in such involvement.

DESIGN

A total of 625 LHDs in a nationally representative stratified random sample of LHDs were administered questions about their participation in PBR activities along with the core instrument in the 2010 National Profile of Local Health Departments Study. Using the Profile data set, zero-inflated negative binomial regression is used to examine the relationships among the variables in the model.

MAIN OUTCOME MEASURE

The dependent variable was a count variable about the number of PBR activities performed by LHDs.

RESULTS

About 62% of LHDs participated in at least one research activity. Participating in research activities was significantly associated with the following characteristics of LHDs: serving a population of 500 000 to 999 999, local governance, having a full-time top executive, having heard of the county health rankings, and having performed a Community Health Assessment in the last 5 years. Of LHDs performing at least one research activity, only LHD jurisdiction size predicted the number of research activities in which LHDs participated. Among these LHDs, the range in participation was from about 12% of research plans developed by LHDs to 37% collected data.

CONCLUSIONS AND IMPLICATIONS

Large public health agencies may be overrepresented, raising the risk that research results may not adequately address the needs, uncertainties, and innovations arising in smaller settings. Correcting this imbalance may require mechanisms for greater involvement of low-resource LHDs in PBR and expanded federal support for such activities through PBR networks.

Comparing types of local public health agencies in North Carolina

CONTEXT

Some states are considering restructuring local public health agencies (LPHAs) in hopes of achieving long-term efficiencies. North Carolina's experience operating different types of LPHAs, such as county health departments, district health departments, public health authorities, and consolidated human services agencies, can provide valuable information to policy makers in other states who are examining how best to organize their local public health system.

OBJECTIVE

To identify stakeholders' perceptions of the benefits and challenges associated with different types of LPHAs in North Carolina and to compare LPHA types on selected financial, workforce, and service delivery measures.

DESIGN

Focus groups and key informant interviews were conducted to identify stakeholders' perceptions of different LPHA types. To compare LPHA types on finance, workforce, and service delivery measures, descriptive statistical analyses were performed on publicly available quantitative data.

SETTING

North Carolina.

PARTICIPANTS

Current and former state and local public health practitioners, county commissioners, county managers, assistant managers, state legislators, and others.

MAIN OUTCOME MEASURE

In addition to identifying stakeholders' perceptions of LPHA types, proportion of total expenditures by funding source, expenditures per capita by funding source, full-time equivalents per 1000 population, and percentage of 127 tracked services offered were calculated.

RESULTS

Stakeholders reported benefits and challenges of all LPHA types. LPHA types differ with regard to source of funding, with county health departments and consolidated human services agencies receiving a greater percentage of their funding from county appropriations than districts and authorities, which receive a comparatively larger percentage from other revenues.

CONCLUSION

Types of LPHAs are not entirely distinct from one another, and LPHAs of the same type can vary greatly from one another. However, stakeholders noted differences between LPHA types-particularly with regard to district health departments-that were corroborated by an examination of expenditures per capita and full-time equivalents per 1000 population.

Obesity prevention: the impact of local health departments

OBJECTIVE

To examine the association between bodyweight status and provision of population-based prevention services.

DATA SOURCES

The National Association of City and County Health Officials 2005 Profile survey data, linked with two cross-sections of the Behavioral Risk Factor Surveillance System (BRFSS) survey in 2004 and 2005.

STUDY DESIGN

Multilevel logistic regressions were used to examine the association between provision of obesity-prevention services and the change in risk of being obese or morbidly obese among BRFSS respondents. The estimation sample was stratified by sex. Low-income samples were also examined. Falsification tests were used to determine whether there is counterevidence.

PRINCIPAL FINDINGS

Provision of population-based obesity-prevention services within the jurisdiction of local health departments and specifically those provided by the local health departments are associated with reduced risks of obesity and morbid obesity from 2004 to 2005. The magnitude of the association appears to be stronger among low-income populations and among women. Results of the falsification tests provide additional support of the main findings.

CONCLUSIONS

Population-based obesity-prevention services may be useful in containing the obesity epidemic.

Leadership matters: local health department clinician leaders and their relationship to decreasing health disparities

OBJECTIVE

The activities that local health departments (LHDs) conduct and their workforce characteristics change over time. We know little, however, about how changes among the services LHDs conduct are associated with the nature of LHD leadership and how these factors impact health. This study investigated changes in LHD services and leadership and how these changes are associated with mortality disparities.

DESIGN

We conducted regression analyses of secondary data using an exploratory panel time series design.

MEASURES

We used secondary data to investigate changes in LHD services and leadership and how these changes were associated with each other and with 1993 to 2005 changes in black-white mortality disparities. Local health department services were examined relative to change in breadth of services within each of 10 program domains between 1993 and 2005. LHD leadership was examined for discipline of the lead executive in 1993 and 2005.

STUDY POPULATION

Our sample included 558 county or multicounty "common local areas," representing county-level data for LHDs and their jurisdictions.

RESULTS

Significant beneficial relationships exist between having a clinician as lead executive in an LHD and reductions in black-white mortality disparities. Local health departments with a clinician (usually a nurse or physician) as their lead executive in 1993 and/or 2005 experienced a significant decrease in black-white mortality disparities for young adults (age 15-44 years) in their jurisdictions from 1993 to 2005 when compared with LHDs with nonclinician leaders.

CONCLUSIONS

The discipline of an LHD's lead executive as a clinician appears to have a significant relationship with the impact of LHD practice on reducing black-white mortality disparities. This study suggests that the discipline of an LHD's leadership may be an important factor to consider in relation to local public health capacity to impact health disparities. Further research related to the mechanisms at play in these relationships is warranted.

The structure and organization of local and state public health agencies in the U.S.: a systematic review

CONTEXT

This systematic review provides a synthesis of the growing field of public health systems research related to the structure and organization of state and local governmental public health agencies. It includes an overview of research examining the influence of organizational characteristics on public health performance and health status and a summary of the strengths and gaps of the literature to date.

EVIDENCE ACQUISITION

Data were retrieved through an iterative process, beginning with key word searches in three publication databases (PubMed, JSTOR, Web of Science). Gray literature was searched through the use of Google Scholar™. Targeted searches on websites and key authors were also performed. Documents underwent an initial and secondary screening; they were retained if they contained information about local or state public health structure, organization, governance, and financing.

EVIDENCE SYNTHESIS

77 articles met the study criteria. Public health services are delivered by a mix of local, state, and tribal governmental and nongovernmental agencies and delivered through centralized (28%); decentralized (37%); or combined authority (35%). The majority of studies focused on organizational characteristics that are associated with public health performance based on the 10 Essential Public Health Services framework. Population size of jurisdiction served (>50,000); structure of authority (decentralized and mixed); per capita spending at the local level; some partnerships (academic, health services); and leadership of agency directors have been found to be related to public health performance. Fewer studies examined the relationship between organizational characteristics and health outcomes. Improvements in health outcomes are associated with an increase in local health department expenditures, FTEs per capita, and location of health department within local networks.

CONCLUSIONS

Public health systems in the U.S. face a number of critical challenges, including limited organizational capacity and financial resources. Evidence on the relationship of public health organization, performance, and health outcomes is limited. Public health systems are difficult to characterize and categorize consistently for cross-jurisdictional studies. Progress has been made toward creating standard terminology. Multi-site studies that include a mix of system types (e.g., centralized, decentralized) and local or state characteristics (e.g., urban, rural) are needed to refine existing categorizations that can be used in examining studies of public health agency performance.

Evidence links increases in public health spending to declines in preventable deaths

Public health encompasses a broad array of programs designed to prevent the occurrence of disease and injury within communities. But policy makers have little evidence to draw on when determining the value of investments in these program activities, which currently account for less than 5 percent of US health spending. We examine whether changes in spending by local public health agencies over a thirteen-year period contributed to changes in rates of community mortality from preventable causes of death, including infant mortality and deaths due to cardiovascular disease, diabetes, and cancer. We found that mortality rates fell between 1.1 percent and 6.9 percent for each 10 percent increase in local public health spending. These results suggest that increased public health investments can produce measurable improvements in health, especially in low-resource communities. However, more money by itself is unlikely to generate significant and sustainable health gains; improvements in public health practices are needed as well.

Explaining the efficiency of local health departments in the U.S.: an exploratory analysis

No study to date has analyzed the efficiency at which local health departments (LHDs) produce public health services. As a result, this study employs data envelopment analysis (DEA) to explore the relative technical efficiency of LHDs operating in the United States using 2005 data. The DEA indicates that the typical LHD operates with about 28% inefficiency although inefficiency runs as high as 69% for some LHDs. Multiple regression analysis reveals that more centralized and urban LHDs are less efficient at producing local public health services. The findings also suggest that efficiency is higher for LHDs that produce a greater variety of services internally and rely more on internal funding. However, because this is the first study of LHD efficiency and some shortcomings exist with the available data, we are reluctant to draw strong policy conclusions from the analysis.
