Increasing Implementation of Evidence-based Interventions at Low-wage Worksites

October 30, 2017 updated by: Peggy Hannon, University of Washington
The proposed project will answer key questions about implementing evidence-based health promotion interventions at small and low-wage worksites. Small, low-wage worksites will be randomized to receive HealthLinks (a free American Cancer Society program to disseminate evidence-based interventions), HealthLinks+ (which will include creating worksite wellness committees as part of the program), or to serve in a delayed control group. This approach will identify successful strategies for implementing evidence-based interventions at low-wage worksites to improve workers' cancer screening, healthy eating, physical activity, and tobacco cessation.

Detailed Description

Cancer and other chronic diseases are leading killers and disablers in the United States, and low-income Americans are at high risk for these diseases. Multiple evidence-based interventions (EBIs) exist to improve chronic disease risk behaviors, such as cancer screening, healthy eating, physical activity, and tobacco cessation, yet EBI reach to community settings is poor. Among community settings for reaching low-income adults, worksites stand out because most low-income adults are employed, but worksite implementation of health-promoting EBIs is low. Half of American workers work in small or low-wage worksites, where implementation of these EBIs and readiness to implement are especially low. Even though decision-makers at these worksites are often motivated to promote worker health, they usually have no dedicated wellness staff and face three major barriers in implementing EBIs: 1) lack of awareness of the potential benefits of EBIs, 2) lack of knowledge to choose EBIs, and 3) lack of financial and personnel resources to implement EBIs. Non-profit organizations and others who would assist these worksites face their own barriers. Organizational readiness to implement EBIs is not well understood, and few validated measures are available, especially for worksites. Without reliable and valid measures of worksite readiness, those who would assist them have difficulty: a) identifying worksites that are ready, and b) helping decision-makers get ready to increase their odds of implementation success. The proposed research will address both sets of barriers and contribute to dissemination and implementation research by testing the efficacy of a worksite EBI dissemination program, HealthLinks, developed in partnership with the American Cancer Society, a non-profit organization operating nationwide. HealthLinks is based on Greenhalgh's diffusion of innovations framework and Rogers' diffusion of innovations theory and addresses small and low-wage worksites' barriers by providing free on-site information and recommendations for EBIs and by providing free on-site programs and temporary staffing to assist implementation. We will test HealthLinks via a 3-arm randomized controlled trial. Worksites will receive either 1) HealthLinks, or 2) an enhanced version of HealthLinks that addresses small worksites' lack of personnel by adding worker wellness committees, or will 3) serve in a delayed control group that receives HealthLinks at study end. We will measure worksites' EBI implementation at baseline, 12 months (at the end of the intervention period), and 24 months (to assess maintenance one year after the intervention ends). This design will test the effectiveness of both HealthLinks and of worker wellness committees. We will also measure the effect of both on workers' health behaviors at baseline, 12 months, and 24 months. Finally, we will develop, pilot-test, and validate a measure of worksite readiness to implement EBIs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Worksite implementation of evidence-based health promotion interventions
Time Frame: up to 24 months
The intervention being tested promotes a package of evidence-based health promotion interventions. The primary outcome is the proportion of these interventions the worksites are implementing at each time-point assessed.
up to 24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Workers' health behaviors related to cancer screening, nutrition, physical activity, and tobacco use
Time Frame: Measured at baseline, 12 months, and 24 months
Workers at participating worksites will complete brief surveys at each time-point assessed that measure their health behaviors related to breast, cervical, and colon cancer screening, healthy eating, physical activity, and tobacco use/cessation.
Measured at baseline, 12 months, and 24 months
