Children with juvenile idiopathic arthritis who require TNF inhibitors often experience insurance-led delays to therapy initiation, according to a research letter published in JAMA Network Open.

Perspective from Jeff R. Peterson, MD

“Although insurance is associated with treatment delays in adults with rheumatoid arthritis, it is unknown if prior authorization (PA) requirements delay [TNF inhibitor (TNFi)] initiation among children with JIA,” Jordan E. Roberts, MD, of Boston Children’s Hospital, and colleagues wrote. “We aimed to characterize delays in TNFi initiation because of insurance among children enrolled in public plans vs private plans.”

Children with juvenile idiopathic arthritis who require tumor necrosis factor inhibitors often experience insurance-led delays to therapy initiation, according to data derived from Roberts JE, et al. JAMA Netw Open. 2022;doi:10.1001/jamanetworkopen.2022.8330

To examine care delays among patients with JIA on private vs. public health insurance plans, Roberts and colleagues compared TNF-inhibitor initiation among newly diagnosed patients between 2018 and 2019 at Boston Children's Hospital. Researchers used automatic extraction to collect patient demographic and insurance information from the hospital’s electronic medical record system.

The researchers compared outcomes from patients enrolled in private and public insurance plans using Wilcoxon tests, t tests and Fisher exact tests.

In total, the researchers identified 54 children and young adults who were prescribed TNF inhibitors for JIA. The average age was 9.9 years and 81% had private insurance. When prior authorizations for TNF inhibitors were first requested, 91% of patients had already received disease-modifying antirheumatic drugs and 61% already received NSAIDs. Prior authorizations for TNF-inhibitor treatment were needed in 98% of cases.

There were 14 cases — or 26% of the total — where prior authorization was denied. Overall, the median time to approval was 3 days in publicly and privately insured patients, though 22% of cases experienced delays longer than 2 weeks. Median approval time in the cases requiring appeals was 15.5 days, compared with 4.8 for therapy approved on the first attempt.

“Children with public and private insurance commonly experienced delays in TNFi initiation because of PA requirements and denials,” Roberts and colleagues wrote. “Although denials were common, all were eventually approved for a TNFi, suggesting that utilization management strategies present barriers to care despite appropriate specialty medication requests, which is consistent with work in adults.

“Our findings highlight barriers to specialty medications for children,” they added. “Currently, no TNFi is FDA-approved for JIA in children under 2, although onset in toddlers is common. Requirements to use specific TNFis may differentially impact children.”
