United Health Foundations Americas Health Rankings, which ranks the states from "least healthy" to "healthiest," receives wide press coverage and promotes discussion of public health issues. The University of Wisconsin Population Health Institute used the United Health Foundations model to develop the Wisconsin County Health Rankings ("Health Rankings") from existing county-level data. The institute first released the rankings in 2004. A survey of the Wisconsin county health officers indicated that they intend to use the rankings for needs assessment, program planning, and discussion with county health boards. The institute implemented many of the health officers suggestions for improvement of the rankings in subsequent editions. The methods employed to create the rankings should be applicable in other states.
RANKINGS CONTRASTING cities, states, or nations for any number of characteristics—economic, education, health, and others—are continuously being released. Such rankings often receive substantial attention. In particular, United Health Foundations annual Americas Health Rankings,1 which ranks states from "least healthy" to "healthiest," receives wide press coverage and promotes discussion of public health issues. The University of Wisconsin Population Health Institute in Madison released its first annual Wisconsin County Health Rankings (hereafter "Health Rankings") report in January 2004, with the main purpose of encouraging discussion about important population health issues among Wisconsin public health and other policy communities. Our hope is that, by encouraging such discussion and raising awareness of variation in populations health within Wisconsin, the Health Rankings will yield an enhanced appreciation of the variety of factors that affect populations health and that are amenable to influence by public and private sector programs and policies. The conceptual framework underpinning the Health Rankings is based on a model of population health improvement with health outcomes produced by a set of health determinants. Public and private sector programs and policies can enhance or limit these determinants.2 We describe briefly the design of the Health Rankings (more-detailed methods can be found elsewhere3), the method of annual release, and an evaluation of the Health Rankings usefulness to local public health authorities.
Design of the Health Rankings The Population Health Institute, in consultation with Wisconsin public health policymakers and other population health stakeholders, developed the first edition of the Health Rankings over an 18-month period. In creating the Health Rankings, we chose to focus on 2 categories of health measures: health determinants and outcomes (Figure 1
We used the Wisconsin State Health Priorities to select health determinant measures.5 We divided 18 health determinant measures into 4 subcategories: access to health care, behaviors, socioeconomic factors, and the physical environment. Each of these categories and subcategories comprises 1 or more underlying measures. Criteria for selecting the measures included being a direct or proxy measure of important aspects of public health, available publicly and updated periodically at the county level, consistently collected across counties, and of sufficient quantity to have moderately stable county-level estimates. We then calculated selected health measures for each county, averaging 1 to 7 years of data depending on sample sizes (more years were averaged for measures with sparser data). Rankings for the health categories and subcategories ranked weighted averages of standardized scores (z scores) for the health measures that made up each health subcategory. Table 1
Release of the Health Rankings The Population Health Institute released its 2003 Health Rankings in early 2004. Local county health officers received a 13-page report by mail 2 weeks before the public release. Institute staff held 2 conference calls in which they described the Health Rankings to health officers and answered any questions. The Health Rankings were made public on the institute Web site and through a press release. Institute staff held an additional conference call with members of the press (primarily newspaper reporters).
The first annual Health Rankings (for 2003) took approximately one and a half years and $100 000 to develop. Roughly 85% of the cost was for personnel, 10% for publication and distribution (several hundred glossy reports and a Web posting), and the remainder for data purchase. Most data were publicly available, but the Wisconsin Department of Health and Family Services charged nominal fees for Wisconsin-specific survey data. Subsequent Health Rankings reports have cost less than half of the initial editions cost. We expect that public or private entities in other states would eventually be able to produce similar reports in 1 year for similar costs. Several weeks after the 2003 Health Rankings release, we mailed surveys to each of Wisconsins 72 county public health officers. The surveys assessed officers awareness of the Health Rankings and their thoughts about the usefulness of the Health Rankings to their work. We sent a second mailing to officers who did not respond and called officers who did not respond to either mailing. The final response rate was 94%.
Table 2
The survey demonstrates that our ranking efforts were useful to the majority of county health officers, many of whom planned to use the rankings in community communications. In response to the survey and additional informal feedback, the Population Health Institute revised the 2004 Health Rankings to improve communication clarity, increase accessibility to the data underlying the rankings (on the institute Web site), and expand the number of health measures used (Figure 1 Media coverage and evidence from the survey indicate that our primary goal for releasing the Health Rankings—encouraging discussion of population health issues within Wisconsin communities—is, in part, being achieved. However, we have found that the Health Rankings were occasionally overinterpreted as though they were designed to be a statistically robust comparator of communities population health status. We discouraged such interpretation because of important limitations of the data underlying the Health Rankings, including survey data sparseness for small-population counties. Thus, with each subsequent release of the Health Rankings, we caution against the overextension of their use (e.g., for tracking changes in health within counties in response to local public health programs). Nonetheless, we strive to enhance our methods and communication strategies so that future editions of the Wisconsin County Health Rankings might provide a continually improving basis for discussion of the distribution and determinants of population health among Wisconsin communities.
The Wisconsin County Health Rankings, their evaluation, and the preparation of this article were supported by core funds of the University of Wisconsin Population Health Institute. We are grateful to Judy Knutson for administrative assistance in all aspects of this project.
