BI’s Article search uses Boolean search capabilities. If you are not familiar with these principles, here are some quick tips.
To search specifically for more than one word, put the search term in quotation marks. For example, “workers compensation”. This will limit your search to that combination of words.
To search for a combination of terms, use quotations and the & symbol. For example, “hurricane” & “loss”.
Vertical integration in medicine is driving up patient care pricing in workers compensation, and provider consolidation is not necessarily translating to improvements in patient outcomes, according to research from the Workers Compensation Research Institute.
The study released Thursday, Impact of Medical Provider Consolidation on Workers’ Compensation Payments, examined the impact of provider vertical integration on comp payments, showing how doctor costs changed after medical practices were acquired by hospitals and health systems.
The study shows there was an 8% increase on the average payment per medical procedure in comp claims involving vertical integration, and it found that the effects of consolidation on medical payments were greater in states with no medical fee schedules designed to control costs.
The study found that between 2012 and 2018, there was an increase in the number of both primary care physicians and orthopedic surgeons practicing at sites owned by hospitals and health care systems, with the former jumping from 32% to 49% and the latter increasing from 18% to 35%.
The researchers said while there are many trends in physician consolidation that are external to workers comp systems, “they still affect many aspects of the medical care provided to workers with injuries.”
“While this work provides suggestive evidence about changes in the utilization of care, more research is needed to examine specific mechanisms behind the changes in the mix of care and access to care when providers become vertically integrated,” the authors wrote.
