A recent paper, Red Herrings and Medical Overdiagnosis Drive Large-Loss Workers’ Compensation Claims published by Keith Rosenblum, senior strategist for Workers’ Compensation Risk Control in Lockton’s Kansas City operation describes what all risk and claims professionals see time and again. The common musculoskeletal injury where recovery stalls, no treatment works and the injury becomes a “creeping catastrophe.”
“Five percent of injured workers account for 80 percent of the cost and lost time in workers’ compensation systems” according to the American College of Occupational and Environmental Medicine. “The majority of these workers end up on long-term disability following injuries that would not be considered serious at their outset.” One-third of Social Security Disability’s recipients are receiving benefits because of musculoskeletal disabilities. Low-back injuries are the most costly, and the most researched, musculoskeletal conditions. Lockton’s large claims database indicates that low back injuries represent 20 percent of all loss dollars. When looking at claims over $250,000, they represent 25 percent of loss dollars.
Studies have shown that in the Medicare population, spinal imaging (especially MRI) rose by a dramatic 300 percent in the last decade reported (1994-2004). During that period, more diagnoses have been based on detected “abnormalities” with a corresponding 300 percent increase in aggressive and expensive treatment. As a consequence, costs have increased roughly tenfold. A similar expense in delivering invasive treatments solely from these imaging studies in workers’ compensation is creating more large loss claims.
These results, according to Lockton, are ‘grossly disappointing’ because outcomes for workers have not improved. In fact, the availability of more precise imaging has meant that workers are disabled longer than historical baselines. Disability rates among working age Americans are higher than at any time in our country’s history, and the problem is getting worse. According to Lockton, If images showing structural abnormalities have not improved results, it looks like patients and medical professionals are going down the wrong path.
Based on the latest science, the Lockton pager says that many of these diagnoses are red herrings. In medicine, a red herring is a diagnosis made based on poor science or inaccurate criteria. False certainty is created, and the search for the actual problem ends. In chronic pain cases, imaging findings are often red herrings. The real source of pain and distress usually lies elsewhere, being generated by soft tissue or by the brain itself, or a combination. Medical overdiagnosis occurs when a physician labels a condition more serious than it truly is, attributing a usually benign condition to causes more serious than the scientific data and situation warrant. The medical literature suggests that in more than 90 percent of common situations, an alleged diagnosis based on MRI “abnormalities” represents medical over-diagnosis.
The American College of Physicians and the American Pain Society put together an independent panel of experts to systematically review world literature concerning low-back pain. Their findings noted many asymptomatic volunteers have changes in their spines that look exactly the same on MRI as spines of people with pain. The panel recommended that many common low-back diagnoses be completely abandoned. These included lumbar disc protrusion, lumbar disc herniation, lumbar spondylosis, and others. The panel advocated that these entities be replaced by the term “nonspecific low-back pain.” This can be interpreted as an acknowledgement that most anatomically based “diagnoses” for pain confer no medical benefit to the patient..
As a solution, the authors of the Lockton paper have been actively following, assessing, and piloting the integration of one of the innovative new models in diagnostic technology that addresses potential chronic pain cases in their various stages of development. “We have been able to definitively identify which of several possible sources is creating a specific worker’s pain by integrating NeuroPAS Global’s NP3 testing methodology along with behavioral medicine assessment in some of our clients’ claims processes. The resulting clarity has enabled more workers to be referred for appropriate physical rehabilitation or cognitive behavioral therapy in lieu of surgery and chronic opioids.” Some insurance carriers and TPAs are working toward or are starting to pilot these technologies earlier in the life of a claim.
Lockton concludes “From a claims perspective, we believe that intervening early in the claim (2-4 weeks) by engaging physicians to comply with medical treatment guidelines, diagnose patients complaints based more on evidence-based medicine and less on imaging studies where not recommended, will make a substantial impact on the 5 percent of workers’ claims and their 80 percent of costs.
