Workers’ Compensation Claims in the Presence of Comorbidities

According to the CDC, 11.6% of Americans have diabetes mellitus, nearly half have hypertension, and 42% are obese. These and many other conditions often co-occur as comorbidities, complicating the health landscape of America’s workforce. The presence of comorbidities not only heightens the risk of workplace injuries but also delays recovery and prolongs return-to-work timelines.

Common Comorbidities and Their Impact on Workers’ Compensation Claims

The most prevalent comorbidities among the working population include obesity, chronic obstructive pulmonary disease (COPD), diabetes, hypertension, and substance abuse. These chronic conditions frequently predispose individuals to injuries or impede effective treatment. According to the Centers for Disease Control and Prevention (CDC), nearly 52% of Americans have at least one chronic condition. Furthermore, the presence of one chronic issue often increases the likelihood of developing others, creating a cascade of health challenges.

Metabolic syndrome, a cluster of cardiometabolic risk factors, significantly impacts workers’ compensation claims. It increases the risk of chronic diseases such as diabetes, cardiovascular disease, and cancer. Metabolic syndrome is diagnosed when at least three of the following are present: increased waist size, elevated triglycerides, low HDL cholesterol, high blood pressure, and elevated blood sugar. According to the National Heart, Lung, and Blood Institute, one in three U.S. adults has metabolic syndrome. Improving cardiometabolic control through lifestyle changes and medications, like GLP-1 agonists, can enhance wound healing and reduce recovery times, aiding injured workers in returning to work sooner.

Risk Factors for Workplace Injuries in the Presence of Comorbidities

Obesity contributes significantly to musculoskeletal injuries. Data from the National Council on Compensation Insurance (NCCI) reveals that over 25% of claims with an obesity comorbidity diagnosis involve sprains and strains. Additionally, obese workers are more likely to experience permanent disability following an injury. Smoking, another critical risk factor, exacerbates back pain by impairing blood flow and causing disc degeneration. Studies show that 36.9% of smokers report some form of back pain, highlighting the detrimental impact of tobacco use on musculoskeletal health.

Carpal tunnel syndrome (CTS), the most common compression neuropathy, frequently affects individuals with diabetes. Diabetic neuropathy elevates the risk of nerve compression disorders. Additionally, hypoglycemia-induced psychomotor impairments increase the risk of falls and traumatic injuries in diabetic workers.

Hypertension also complicates workers’ compensation claims by contributing to microvascular disease, which impairs blood flow and oxygen delivery. These effects delay wound healing, muscle recovery, and rehabilitation, prolonging workers’ time away from their jobs.

Presence of Comorbidities and Treatment Challenges

Comorbidities often delay or complicate treatment plans for workplace injuries. For instance, steroid injections, commonly used for pain management, are contraindicated in poorly controlled diabetes due to their hyperglycemic effects. Similarly, morbid obesity increases surgical risks, prompting many surgeons to recommend medical optimization before proceeding with elective procedures. Tobacco use further complicates recovery by increasing the risk of wound infections and chronic pain.

Even non-surgical treatments can be affected. Obese workers, for example, miss an average of 13 more workdays than their non-obese counterparts. When additional comorbidities like diabetes are present, recovery times extend further due to complications such as delayed wound healing.

Apportionment in Workers’ Compensation Claims Involving Comorbidities

When evaluating workers’ compensation claims, Qualified Medical Evaluators (QMEs) must carefully apportion disability between workplace injuries and preexisting conditions. For example, an obese employee with a knee injury will experience heightened symptoms and longer recovery due to added joint stress. Labor Code §4663(a) mandates that apportionment consider the causation of disability rather than merely identifying risk factors.

Diabetes presents unique challenges in apportionment decisions. Chronic, uncontrolled diabetes often leads to complications such as peripheral neuropathy and carpal tunnel syndrome. However, even well-managed diabetes carries some risk of these conditions. When causation is unclear, QMEs must rely on objective medical evidence, such as bilateral nerve conduction studies, to determine the extent of disability attributable to workplace injuries versus preexisting conditions.

The Lindh decision, stemming from the City of Petaluma v. WCAB case, clarified that apportionment can include asymptomatic preexisting conditions if they significantly contribute to disability. In this case, a police officer’s vision loss was attributed primarily to an underlying vascular condition, even though it was asymptomatic before the workplace incident. This precedent underscores the importance of a thorough medical evaluation in complex claims.

Addressing the Challenges of Comorbidities in Workers’ Compensation

Comorbidities undeniably complicate workers’ compensation claims, but proactive measures can mitigate their impact. Medical and legal professionals must:

  1. Optimize Health Before Injuries: Encouraging preventive healthcare can reduce the severity of comorbidities and their impact on workplace injuries.
  2. Use Evidence-Based Approaches: QMEs must rely on objective data to apportion disability accurately and ethically.
  3. Advocate for Fair Practices: Ensuring injured workers receive timely, appropriate care despite comorbidities supports equitable outcomes.
