Abstract
OBJECTIVES: To assess whether children with medical complexity (CMC) exposed to a hospital-based comprehensive case management service (CCMS) experience improved health care quality, improved functional status, reduced hospital-based utilization, and/or reduced overall health care costs. METHODS:Eligible CMC at Seattle Children's Hospital were enrolled in a cluster randomized controlled trial between December 1, 2010, and September 29, 2014. Participating primary care providers (PCPs) were randomly assigned, and CMC either had access to an outpatient hospital-based CCMS or usual care directed by their PCP. The CCMS included visits to a multidisciplinary clinic ≥ every 6 months for 1.5 years, an individualized shared care plan, and access to CCMS providers. Differences between control and intervention groups in change from baseline to 12 months and baseline to 18 months (difference of differences) were tested. RESULTS:Two hundred PCPs caring for 331 CMC were randomly assigned. Intervention group (n = 181) parents reported more improvement in the Consumer Assessment of Healthcare Providers and Systems version 4.0 Child Health Plan Survey global health care quality ratings than control group parents (6.7 [95% confidence interval (CI): 3.5-9.8] vs 1.3 [95% CI: 1.9-4.6] at 12 months). We did not detect significant differences in child functional status and most hospital-based utilization between groups. The difference in change of overall health care costs was higher in the intervention group (+$8233 [95% CI: $1701-$16 937]) at 18 months). CCMS clinic costs averaged $3847 per child-year. CONCLUSIONS: Access to a CCMS generally improved health care quality, but was not associated with changes in child functional status or hospital-based utilization, and increased overall health care costs among CMC.
