What Can You Achieve in Eight Years? A Case Study on Participation, Effectiveness, and Overall Impact of a Comprehensive Workplace Health Promotion Program.

OBJECTIVE To investigate participation and effectiveness of a multiyear comprehensive workplace health promotion (WHP) program. METHODS Participation and effectiveness data came from employer and vendor systems. Health data came from health risk assessments (HRA) and biometric screenings. Participation and effectiveness were analyzed using descriptive analyses, T-tests and Mann-Whitney U tests where appropriate. Overall impact was assessed using the PIPE Impact Metric. RESULTS 86% of employees completed the HRA and 80% the biometrical screenings. Annual participation rate was 24%, and total reach was 58%. The portion of successful participants was 23% in 2010-2013 and 18% in 2014-2017. PIPE Impact scores were 18% for 2010-2013 and 14% for the 2014-2017 study periods. CONCLUSION Despite modest annual participation rates, overall eight year reach was considered reasonable. Conservatively, we consider the overall program impact to be moderate.
