2 Workplace Health Promotion/Health Protection Programs: What Should be Evaluated? Structure Process Outcomes

LOGIC MODEL: WORKSITE PROGRAMS STRUCTURE PROCESS OUTCOMES Modified Worksite Health Promotion (Assessment of Health Risk with Follow-Up) Logic Model adopted by the CDC Community Guide Task Force HEALTH PROMOTION/PROTECTION Employees

5 Program Structure Structure defines the program -- how does it work – the WHAT, HOW & WHEN? Individual components, e.g., HRA, feedback reports, mailings, internet services, high risk counseling, referral to community resources, incentives Environmental components, e.g., organizational policies, cafeteria/vending machine choices, time off for health promoting activities, senior management support, access to physical activity programs, walking paths, shower/change facilities, healthy company culture

12 PROGRAM PROCESS Program process evaluation defines how well the program is carried out: – Participation rates – Satisfaction with the program/process/people – Completion rates

GOAL: To summarize program implementation and to form hypotheses about how implementation may affect program outcomes To monitor progress during a program implementation and to inform potential adjustments to the program to improve program quality – Program Fidelity (quality) - how the program was implemented – Dose Delivered (completeness) – frequency and intensity of the program – Dose Received (satisfaction) - how participants react to the intervention – Program Reach (participation rate) –The proportion of eligible (employees) that participated in the various components of the programs?

Program Impacts 17

18 PROGRAM OUTCOMES Program outcomes are evaluated by determining whether program objectives are achieved, at a given level of quality, and within a defined time framework – Health outcomes Behavior change Risk reduction – Medical care outcomes Health care utilization Health care costs – Productivity outcomes Absenteeism Disability Workers’ compensation/safety Presenteeism

RESEARCH DESIGN Pre-experimental Quasi- experimental True experimental Validity of results increases as you move down this list All are tools that can help understand the impact of the program 19

NON-EXPERIMENTAL DESIGN (PRE-EXPERIMENTAL) 20 Program start

22 PROBLEMS WITH A PRE-EXPERIMENTAL DESIGN: REGRESSION TO THE MEAN The most simple analysis may produce the wrong answers Before the Intervention Intervention Period Savings? Same people

26 RETURN ON INVESTMENT AND NET PRESENT VALUE Return on Investment (ROI) = Savings Program Cost = $1 break-even Net Present Value (NPV) = Savings – Program Cost = $0 break-even

27 Cost-Benefit (ROI) Analysis Wellness Program Costs, Highmark, inflation-adjusted to 2005 dollars

28 Evaluators must explicitly state the intervention pathway and metrics used to measure: – The “cause” or actual intervention – The “effect” – proximate and/or ultimate outcomes that result from the intervention Hypotheses that outcomes are “caused” by the HP program must be articulated and tested Assessing Causality HP Program Proximate Outcomes Ultimate Outcomes Effect Cause

CRITICAL STEPS TO SUCCESS Reduced Utilization Risk Reduction Behavior Change Improved Attitudes Increased Knowledge Participation Awareness Financial ROI 29

HEALTH RISKS – HEALTH BEHAVIORS -- ADJUSTED Results adjusted for age, sex, region * p<0.05 ** p<0.01

ADJUSTED MEDICAL AND DRUG COSTS VS. EXPECTED COSTS FROM COMPARISON GROUP Average Savings = $565/employee/year Estimated ROI: $ $3.92 to $1.00

33 Summary Evaluation of Health Promotion/Protection Programs is doable, but tricky Know your audience – the level of sophistication in conducting financial analyses varies significantly – well done studies are complex and expensive It’s easy to come up with the “wrong” answer if the proper research design is not used Ask for help – good evaluation studies require a team of individuals with diverse backgrounds and skill sets Tell the truth, the whole truth, even if it means saying the program didn’t work
