Insights
Children with medical complexity (CMC) often miss annual well-child visits (WCVs). Consistent WCVs are linked to fewer hospitalizations, highlighting the need to improve access for these vulnerable children.
Area of Science:
- Pediatric Health Services Research
- Healthcare Access and Utilization
Background:
- Well-child visits (WCVs) are crucial for optimizing child health outcomes.
- Children with medical complexity (CMC) represent a vulnerable population with unique healthcare needs.
- Understanding WCV utilization patterns in CMC is essential for improving care coordination and health outcomes.
Purpose of the Study:
- To measure annual WCV utilization among children with medical complexity (CMC).
- To correlate WCV frequency with hospitalization rates in CMC.
- To identify factors influencing WCV adherence in this population.
Main Methods:
- Retrospective analysis of 93,121 CMC aged 1-18 years enrolled in state Medicaid programs (2010-2014).
- CMC defined by complex chronic conditions or multiple chronic conditions and medication use.
- Statistical analysis (chi-squared test, logistic regression) to assess WCV-years and hospitalization relationships.
Main Results:
- Over 5 years, 13.4% of CMC had no WCVs; 28.5% had WCVs in 4-5 years.
- Lower WCV rates observed in fee-for-service Medicaid and for children enrolled due to disability.
- Increased WCV frequency correlated with decreased hospitalization rates (21.5% at 0 years vs. 16.9% at 5 years).
Conclusions:
- A significant proportion of Medicaid-insured CMC lack consistent annual WCVs.
- Fewer WCVs are associated with a higher likelihood of hospitalization in CMC.
- Interventions are needed to enhance WCV utilization among children with medical complexity.
Objective:
Well-child visits (WCVs) help optimize children's health. We measured annual WCVs for children with medical complexity (CMC) and correlated WCVs with hospitalizations.
Study Design:
This was a retrospective analysis of 93 121 CMC aged 1-18 years continuously enrolled in 10 state Medicaid programs in the Truven MarketScan Database between 2010 and 2014. CMC had a complex chronic condition or 3 or more chronic conditions of any complexity identified from International Classification of Diseases, Ninth Revision codes, and the use of 1 or more chronic medications. We measured the number of years with 1 or more WCVs. The χ2 test and logistic regression were used to assess the relationships of WCV-years with the children's characteristics and hospitalization.
Results:
Over 5 years, 13.4% of CMC had 0 WCVs; 17.3% had WCVs in 1 year, 40.8% had WCVs in 2-3 years, and 28.5% had WCVs in 4-5 years. Fewer children received WCVs in 4-5 years when enrolled in Medicaid fee-for-service compared with managed care (20.9% vs 31.5%; P < .001) and when enrolled due to a disability compared with another reason (18.2% vs 32.2%; P < .001). The percentage of CMC hospitalized decreased as the number of years receiving WCV increased (21.5% at 0 years vs 16.9% at 5 years; P < .001). The adjusted odds of hospitalization were higher in CMC with WCVs in 0-4 years compared with CMC with WCVs in all 5 years (OR range across years, 1.1 [95% CI, 1.0-1.2] to 1.3 [95% CI, 1.3-1.4]).
Conclusions:
Most Medicaid-insured CMC do not receive annual WCVs consistently over time. Children with fewer annual WCVs have a higher likelihood of hospitalization. Further investigation is needed to improve the use of WCVs in CMC.
