ATLANTA — Patients with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) are at a higher risk for an opioid overdose-related hospitalization compared with the general population, according to research results presented at the 2019 American College of Rheumatology/Association of Rheumatology Professionals (ACR/ARP) Annual Meeting, held November 8 to 13, 2019, in Atlanta, Georgia.

Researchers sought to assess the rates of opioid-overdose related hospitalizations in patients with SLE and RA compared with the general population. Data were collected from the National Inpatient Sample, which provides annual estimates of >35 million hospitalizations across the United States. Opioid overdose-related hospital admissions with RA and SLE were based on the International Classification of Diseases, Tenth Revision, Clinical Modification system. Chi-squared tests and Poisson regression were used for comparison and modeling, respectively.

The analysis included data from 33,207,455 hospitalizations in 2016; 512,740 (1.5%) of these included patients with RA and 147,480 (0.44%) with SLE. Patients with RA or SLE had a higher percentage of hospitalizations with a primary cause of opioid overdose compared with patients with neither condition (0.23% and 0.34% vs 0.17%; P <.01). When including all diagnoses of opioid overdose, the proportions of hospitalizations increased for groups with RA, SLE, and the general population (1.46%, 1.50%, and 0.85%, respectively).

After accounting for demographic characteristics and socioeconomic status, both RA and SLE were associated with higher relative risks for opioid overdose-related hospitalizations compared with patients with neither condition. Compared with patients with RA, those with SLE was associated with a higher relative risk for opioid overdose hospitalization.

“RA and SLE were associated with a 1.5 to 2-fold higher risk [for] opioid overdose hospitalization compared [with] the general population,” the researchers concluded. “Local and national overdose intervention programs should consider targeting [patients with] RA and SLE as at potentially increased risk for opioid overdose.”
