Abstract

General practitioners (GPs) are central to the treatment and management of injured workers. Australian workers' compensation funds GP consultations for work-related injuries. Almost all other GP consultations are subsidised by public healthcare insurance (Medicare Benefit Scheme). This study aimed to examine changes in publicly-insured GP consultations before and after injury for injured workers with long-duration claims, focusing on consultation duration types and GP-provided mental health and chronic diseases management plans.
This retrospective cohort study using interrupted time series analysis included 3,755 injured workers and 10,113 community individuals with injury/index date between 2006 and 2016. We compared monthly changes in rates (per 1000 workers) of six GP consultation types for 12-month before and 24-months after injury. Acute and long-term changes were examined both overall (combining all consultation types) and separately by consultation type. Consultation types include four duration-based levels: A (0-6 min), B (6-20 min), C (20-40 min), and D (40-60 min), and two types describing mental health and chronic disease management plans.
After injury, injured workers received an additional 1,600 Medicare-subsidised GP consultations per 1,000 workers per year compared to the community group. Post-injury, the largest increase in monthly consultation rates was observed for Level D consultations (IRR: 2.37, 95% CI: 1.35, 4.20), while the smallest increment was observed for Level B consultations (IRR: 1.45, 95% CI: 1.32, 1.59). Monthly GP mental health care and chronic disease development plan rates increased by 84% (IRR: 1.84, 95% CI: 1.17, 2.93) and 20% (IRR: 1.20, 95% CI: 0.78, 1.86) post injury, respectively; however, the monthly rates of these consultations were small (maximum 25/1000 workers) Following these initial increases immediately post-injury, monthly consultation rates decreased by 3% to 9% and by 24-months post-injury had returned to levels observed in the comparison group.
All six types of publicly insured GP consultations increased temporarily in the initial months following injury, regardless of worker's compensation status. These consultations remained elevated above pre-injury levels for over 12 months, likely reflecting delayed claim acceptance or increased care needs. These findings highlight the need of a comprehensive, whole-person approach to recovery that addresses both immediate and broader healthcare needs.
