Effectiveness of compliance with pediatric preventive care guidelines among Medicaid beneficiaries
Insights
Regular well-child visits in the first two years significantly reduce avoidable hospitalizations for low-income children. This study highlights the importance of consistent preventive care for improving child health outcomes.
Area of Science:
- Pediatrics
- Public Health
- Health Services Research
Background:
- Previous research has not definitively linked infant health supervision compliance to improved health outcomes.
- Adherence to preventive care guidelines is crucial for child well-being.
- Avoidable hospitalizations serve as key indicators of adverse health outcomes in children.
Purpose of the Study:
- To investigate the association between adherence to periodic health supervision guidelines and the incidence of avoidable hospitalizations in children.
- To determine if consistent well-child visits and immunizations impact child health outcomes.
- To evaluate the effectiveness of preventive care in reducing hospitalizations among vulnerable populations.
Main Methods:
- A historic cohort study involving 308,131 children enrolled in Medicaid at birth.
- Medicaid records were linked across three years to track health supervision and hospitalizations.
- Survival analysis was used, with avoidable hospitalizations as health indicators, referencing American Academy of Pediatrics (AAP) guidelines.
Main Results:
- Children up-to-date with well-child visits had significantly lower rates of avoidable hospitalizations across California, Georgia, and Michigan.
- Sporadic preventive care visits offered a minor benefit for children not adhering to the schedule.
- Immunizations and race/ethnicity did not show a consistent relationship with avoidable hospitalizations.
Conclusions:
- Consistent well-child visits during the first two years positively impact health outcomes by decreasing avoidable hospitalizations for poor and near-poor children.
- These benefits were observed irrespective of race, poverty level, or initial health status.
- National initiatives should prioritize increasing compliance with periodic preventive care for young children, alongside immunization efforts.
Objective:
Because research has not confirmed a relationship between compliance with health supervision in infancy and improved health outcomes, we examined the association between adherence to prevailing guidelines for periodic health supervision and adverse health outcome indicated by incidence of avoidable hospitalizations.
Methods:
This was a historic cohort study of 308 131 children enrolled in Medicaid at birth in California, Georgia, and Michigan in 1990 using Medicaid records linked across 3 years. We used avoidable hospitalizations as indicators of health in a survival analysis. The analysis used variables that represented completeness and timeliness of well-child visits and immunizations using AAP guidelines for health supervision as the gold standard.
Results:
When the children in this cohort were up-to-date for age on their schedule of well-child visits, they were less likely to have an avoidable hospitalization (race, illness, and level of poverty adjusted hazard ratios 0.52 [95% confidence interval (CI): 0.50-0.55] in California, 0.54 [95% CI: 0.50-0.55] in Georgia, and 0.7 [95% CI: 0.69-0.79] in Michigan). Among children who were not up-to-date with well-child visits, a sporadic preventive care visit conferred a mild benefit. Immunizations and race/ethnicity had no consistent relationship with incidence of avoidable hospitalizations.
Conclusions:
A series of well-child visits maintained during the first 2 years of life has a positive effect on health outcomes as indicated by a decrease in avoidable hospitalizations among poor and near-poor children, regardless of race, level of poverty, or health status. National efforts to improve the quality of child health services for young children should focus on increasing compliance with periodic preventive care for young children in addition to improving immunization levels.
