Trends in the Health Care Use and Expenditures Associated With No-Lost-Time Claims in Ontario

OBJECTIVE: To examine trends in health care usage and expenditures associated with no-lost-time claims in Ontario over a 15-year period. METHODS: A secondary analysis of administrative workers' compensation claims occurring between 1991 and 2006 (N = 2,290,101). We used regression analysis to model health care expenditures using a zero-inflated linear model, adjusting for age, gender, industry group and size of payroll.
