Objective: To determine the continuity of care (CoC) provided by general practitioners among workers with low back pain; identify personal, workplace and social factors associated with CoC in this population; and investigate if CoC is associated with working time loss.
Data sources: An administrative database containing accepted workers' compensation claim and service level data, for workers with back pain from five Australian jurisdictions, injured between July 2010 and June 2015.
Study Design: A retrospective cohort study. Outcomes were CoC with a general practitioner, measured with the Usual Provider Continuity index, and working time loss, measured as the number of weeks for which workers' compensation income support benefits were paid.
Extraction methods: Eligible workers had at least four general practitioner services, and greater than two weeks working time loss. Usual Provider Continuity index score was categorised as complete, high, moderate, or low CoC. Ordinal logistic regression models examined factors associated with Usual Provider Continuity category. Quantile regression models examined association between duration of working time loss and Usual Provider Continuity category, in four groups with different volumes of general practitioner services.
Principal Findings: Complete CoC was observed in 33.8% of workers, high CoC among 37.7%, moderate CoC in 22.1%, and low CoC in 6.4%. Higher Usual Provider Continuity was associated with fewer general practitioner services, older age, living in urban areas, an occupation as a Community and Personal Service Worker or Clerical and Administrative Worker, and the state of Victoria. In workers with more than two months of time loss, those with complete CoC consistently had shorter durations of time loss.
Conclusions: Higher CoC with a general practitioner is associated with less working time loss and this relationship is strongest in the sub-acute phase of low back pain.
