Case Study
Outcomes Overview
Hyatt management deployed Optisom’s ProjectZ as key part of their ongoing wellness initiatives. The outcomes of ProjectZ were measured using a baseline screening and follow-up assessments at the midpoint and endpoint of the program. Based on the results, ProjectZ significantlyimproved the sleep health of the employee population, resulting in higher productivity for Hyatt and better health for Hyatt employees.
ProjectZ reduced the prevalence of sleep deprivation by 67%, as measured through midpoint or endpoint assessments.
ProjectZ reduced the symptoms of insomnia by 90%, as measured through midpoint or endpoint assessments.
Based on productivity gains alone, Hyatt realized an 8x return on investment. The productivity gains were quantified using the Work Limitations Questionnaire, an industry accepted measurement tool.
In addition to improved sleep, the majority of employees surveyed expressed an improvement in their overall health, reinforcing restorative sleep as a foundation for health.
Population And Outcomes Data
Population Level Data
Hyatt has an established culture of health, with broad executive support for wellness initiatives. This allowed ProjectZ to be marketed effectively to the employee population. The baseline screenings showed a high prevalence of sleep health issues in the employee population, correlating with the high rate of obesity. Population level data from the ProjectZ program is shown below. Even without factoring in reduced health care costs and safety savings, the client realized an 8x return on investment from the productivity gains alone.
