Time to First Completed Visit and Health Care Utilization Among Young Adults Transferring From Pediatric to Adult Rheumatologic Care in a Safety-Net Hospital.

Objective: The transfer from pediatric to adult care for young adults is a vulnerable period. Our objectives were to quantify the time between the final pediatric and the first adult visit and to evaluate unscheduled utilization in care and progression to end-stage renal disease (ESRD) or death.

Methods: We conducted a retrospective analysis of pediatric patients transferring to a large adult rheumatology clinic. Outcomes included time to first completed adult visit, unscheduled health care utilization (hospitalizations and emergency department [ED] visits), and progression to ESRD or death. Multivariable regression models assessed variables predictive of outcomes of interest.

Results: A total of 141 pediatric patients who transferred care were identified: 77% female, 65% Hispanic, and 60% with connective tissue diseases (CTDs). The mean time between final pediatric and first completed adult rheumatology visit was 221 days (range 0-1,207 days). In regression modeling, we found that continued insurance coverage, younger age at referral, and referral from a pediatric rheumatologist were predictive of shorter time to completed adult visit (P < 0.005). Factors associated with hospitalizations and ED visits included CTD diagnosis and Black race (odds ratio [OR] 8.54 [95% confidence interval (95% CI) 1.84-39.58] and 3.04 [95% CI 1.02-9.12] for hospitalizations and OR 3.6 [95% CI 1.59-8.14] and 6.0 [95% CI 1.60-22.69] for ED visits, respectively). ESRD or death occurred among 15% of patients with a CTD.

Conclusion: In pediatric patients transferring to an adult rheumatology clinic, continued insurance coverage and referral from a pediatric rheumatologist decreased delays in attending an adult visit; CTD and Black race were associated with high rates of unscheduled health care utilization.
