Characterizing the contribution of chronic pain diagnoses to the neurologic burden of disease, active component, U.S....

In the annual Medical Surveillance Monthly Report (MSMR) burden of disease analysis, neurologic disorders represent the fifth most common category of diagnoses among active component service members within the Military Health System. One major subcategory of this disease group is "all other neurologic conditions." Incidence analysis from 2009-2018 revealed that the vast majority of diagnoses in this undefined subcategory were related to chronic pain and that such diagnoses have been increasing in burden by a considerable amount. Chronic pain diagnoses increased from a rate of 85.5 per 10,000 person- years (p-yrs) in 2009 to 261.1 per 10,000 p-yrs in 2018. Subgroup analysis by demographic characteristics demonstrated that female, non-Hispanic black, older, and enlisted personnel were at increased risk for chronic pain diagnoses. Among the branches of service, members of the Army were at the highest risk of a chronic pain diagnosis with a rate ratio of 4.8 compared to the Navy, the branch with the lowest risk. Future annual burden analyses should consider chronic pain as its own subcategory to better characterize its impact.
