title: Two-year follow-up of the Collision Auto Repair Safety Study (CARSS).
abstract: This paper presents an evaluation of the sustainability of health and safety improvements in small auto collision shops 1 year after the implementation of a year-long targeted intervention. During the first year (active phase), owners received quarterly phone calls, written reminders, safety newsletters, and access to online services and in-person assistance with creating safety programs and respirator fit testing. During the second year (passive phase), owners received up to three postcard reminders regarding the availability of free health and safety resources. Forty-five shops received an evaluation at baseline and at the end of the first year (Y1). Of these, 33 were evaluated at the end of the second year (Y2), using the same 92-item assessment tool. At Y1, investigators found that between 70 and 81% of the evaluated items were adequate in each business (mean = 73% items, SD = 11%). At Y2, between 63 and 89% of items were deemed adequate (mean = 73% items, SD = 9.5%). Three safety areas demonstrated statistically significant (P < 0.05) changes: compressed gasses (8% improvement), personal protective equipment (7% improvement), and respiratory protection (6% decline). The number of postcard reminders sent to each business did not affect the degree to which shops maintained safety improvements made during the first year of the intervention. However, businesses that received more postcards were more likely to request assistance services than those receiving fewer.
