A population health improvement initiative typically begins with a thorough assessment of needs and resources. This entails gathering and analyzing quantitative and qualitative data, inclusive of all appropriate populations.
The goal is to establish a solid basis for determining priorities, determining goals and strategies, and evaluating outcomes.
- Quantitative data is information that can be measured in numbers and may indicate prevalence and trends. Because it can be measured in numbers, this type of data lends credibility to your assessment.
- Qualitative data is available from multiple sources and is information that is non-numeric. It can help with understanding the “why and how” of a population’s health status. Qualitative data can be gathered from surveys, focus groups, key informant interviews, environmental scans, and asset mapping.
When doing assessments, it’s also important to pay attention to health equity and the Social Determinants of Health. Learn more by expanding the options below. Resources on these topics may be found below.
What is Health Equity and why is it important to population health?
Simply put, health equity means equal access to health (not just healthcare) for all members of our population. Achieving health equity requires partners to be alert to the unique strengths and vulnerabilities of subpopulations within a patient panel or geographic region.
The Guide offers data and resources on health equity concerns specific to some priority health issues. In addition, the resources below offer guidance on applying a health equity lens to population health:
Department of Health’s website provides health equity definitions, literature and tools for policy planning.
Washington Health Alliance 2016 Disparities in Care Report offers information on disparities in care among minority populations in Washington State.
American Indian Health Commission provides a wealth of information on tribal health in Washington State. A unique aspect to working with tribal partners is the sovereignty of American Indian and Alaska Native (AIAN) nations, and operating within the government-to-government relationship. Other important considerations include the overlap of tribal boundaries with health system regions, and the needs of the Urban Indian population as contrasted with those living on reservations.
Foundation for Healthier Generations website provides information on some of the nuances of health equity, including how it intersects with social determinants of health such as housing and employment.
The Centers for Disease Control and Prevention offers health equity resources related to Chronic Disease Prevention and Health Promotion. The site includes links to health equity information on specific physical and behavioral health issues.
According to Healthy People 2020, social determinants of health are conditions in which people live their lives that impact health and quality of life. These conditions are both physical and social.
How clean is the air? How safe are the streets? What about housing? Employment? These are all factors in population health and are important to consider when conducting an assessment. For example, if your community is focusing on prevalence of obesity and diabetes, are you also tracking access to healthy food and physical activity?
Challenge: National or state data may not reflect your community, and local data may not be available.
Try: Engage community partners in local surveys, key informant interviews and focus groups. If you have a nearby community college or university, contact a health occupations or sociology instructor to see if gathering local data could be a class or individual student project. For tools on gathering good qualitative data, see the Assessment Resources Tools at the bottom of this page.
Challenge: Available data, even when local, may not provide enough data for a subpopulation.
Try: Reach out to local schools and nonprofit organizations. They may have data available and/or be able to help gather it. Explore grant and philanthropic funding to support the data gathering. Also, let your local health jurisdictions and tribal governments know what your data needs are. Your input can help their data teams plan future state and local assessments.
Give us your feedback and we will share with appropriate local and state data stewards. Send comments to P4IPH@doh.wa.gov.
Challenge: Data may not adequately reflect social determinants.
Try: Resources such as the Washington Tracking Network (link below) can help. Also, local government and community partners may have qualitative data to provide. Some communities have engaged partners and volunteers in Photovoice (described in Assessment Tools below) projects, to capture social determinant information in a way that can drive policy change.
- Washington State Health Assessment provides a wealth of data and analysis. The assessment includes population trends, disparities, health outcomes, health behaviors, access to care, the physical and built environment, and social determinants.
- Health of Washington State Report provides the most recent health status update for the state.
- Healthier Washington Data Dashboard gives partners access to interactive tool. It is provided to all Accountable Communities of Health and local health jurisdictions.
- Data and Health Outcomes Summary for Washington State offers county level information from the national County Health Rankings.
- Health Behaviors of Washington State provides data on behaviors and attitudes that affect health
- Behavioral Health Decision Support, provides data on Substance Abuse and Mental Health
- Washington Tracking Network provides information related to the Social Determinants of Health; the conditions where we live, learn, work, play that impact our health.
These resources can help with gathering qualitative data:
- For a picture of a community health issue related to health equity check out "Using Photovoice to Understand Barriers", from the Centers for Disease Control and Prevention (CDC)
- For help conducting an assessment to inform your population health plan, read the Community Health Assessment for Population Health Improvement report, also from the CDC.
- It’s not just about the health problems we have, it’s about the resources we have to address them. For help with this, see Community Asset Mapping, from the National Association of County and City Health Officials (NACCHO)
- There’s a big difference between just talking with people, and gathering quality information from key informants and focus groups. Evidence-based tools: Guide to effective focus groups and Guide to Key Informant Interviews, from UCLA Center for Health Policy Research.
