Impacts of Workplace Health Promotion and Wellness Programs on Health Care Utilization and Costs: Results From an Academic Workplace.

OBJECTIVE: This study evaluated the impacts of a long-standing workplace health promotion (HP) program on health care utilization and costs and estimated return on investment (ROI). METHODS: Analyses used a retrospective, observational cohort design based on 7 years (2005 to 2011) of health claims and HP program participation data for 3829 HP participants and 6617 controls. Inverse propensity score-weighted mixed-model regression methods were used to balance employee demographics and comorbidities by study arm. RESULTS: Mean monthly health care costs were $35 less for HP participants compared with controls, and results were robust based on sensitivity analyses. ROI was estimated to be $2.53 for every dollar spent on the HP program. CONCLUSIONS: Results support a positive impact of HP program participation with regard to reduced health care utilization and costs and a positive ROI.

Nail gun injuries among construction workers.

Pneumatic nail guns greatly increase worker productivity and are extensively used in wood frame building construction, with especially high use in residential construction. One surveillance report of nail gun injuries in Washington State has been published; however, other literature consists largely of case reports and case series in trauma journals. The major objective of the current study was to investigate the occurrence of nail gun-associated injuries among construction workers and to identify preventable work-related factors associated with these injuries. Nail gun-related injuries occurring among a cohort of 13,347 carpenters in Ohio who worked union hours during the time period January 1, 1994, until September 30, 1997, were identified by matching the cohort with workers' compensation claims made to the Ohio Bureau of Workers' Compensation. We also analyzed workers' compensation claims for North Carolina Home Builders Association members for the period July 1996-November 1999 to identify nail gun-related injuries. Analyses included stratified analyses of claims by nature and body part injured, calculation of nail gun injury rates, and analyses of free text descriptions of injuries. Overall, nail gun injuries were responsible for 3.9 percent of workers' compensation claims with 8.3 percent to 25.5 percent of claims involving paid lost work time. The overall rate of nail gun injuries (cases per 200,000 work hours) was 0.33 in North Carolina and 0.26 in Ohio, reflecting the greater concentration of wood frame construction workers in the North Carolina population studied. Higher rates of injury were observed for carpenters in North Carolina and among residential carpenters in Ohio. The predominant body part injured was the hands/fingers, with 80 to 89 percent of injuries being nail punctures. Analyses of free text information for puncture injuries found approximately 70 percent of injuries to occur during the framing/sheathing stage of construction. Our data suggest that approximately 69 percent of puncture injuries may be due to an inadvertent gun discharge or misfire, preventable in large part by the use of sequential triggers. Worker training and education also are important components of nail gun injury prevention.
