Insights
Children’s social risk factors are linked to more emergency department (ED) visits and hospitalizations. However, these factors did not significantly affect the timing of a child’s first subsequent ED visit or hospitalization.
Area of Science:
- Pediatric Health
- Social Determinants of Health
- Healthcare Utilization
Background:
- Social risk factors significantly impact child health outcomes and healthcare access.
- Understanding the relationship between social risks and healthcare utilization is crucial for targeted interventions.
- Previous studies highlight the need to screen for social determinants of health in pediatric populations.
Purpose of the Study:
- To investigate the association between children's social risk factors and emergency department (ED) visits or hospitalizations.
- To determine if social risk factors influence the time to a child's first subsequent ED visit or hospitalization.
- To quantify the impact of the number and type of social risk factors on healthcare utilization.
Main Methods:
- Retrospective cohort study of 4674 pediatric patients from 2017-2021.
- Utilized negative binomial or Poisson regression to model ED and hospitalization rates based on social risk factors.
- Employed time-varying Cox models to assess the time to first subsequent ED visit or hospitalization, controlling for covariates.
Main Results:
- Children with social risk factors had higher rates of ADHD, failure to gain weight, asthma, and prematurity.
- Increased social risk factors were associated with higher rates of ED utilization (IRR, 1.18) and hospitalizations (IRR, 1.36).
- No significant association was found between social risk factors and the time to first ED visit (HR, 0.95) or hospitalization (HR, 1.15).
Conclusions:
- Social risk factors are associated with increased overall ED utilization and hospitalizations in children.
- The presence of social risk factors did not significantly alter the time to subsequent acute care use.
- Further research should focus on interventions addressing specific social risks like food insecurity and transportation to reduce healthcare utilization.
Objective:
To characterize the association of children's social risk factors with total number of emergency department (ED) visits or hospitalization and time to first subsequent ED or hospitalization.
Study Design:
This was a retrospective cohort study of patients seen at a general pediatric clinic between 2017 and 2021 with documented ≥1 social risk factors screened per visit. Negative binomial or Poisson regression modeled ED utilization and hospitalizations as functions of the total number of risk factors or each unique risk factor. Time-varying Cox models were used to evaluate differences between those who screened positive and those who screened negative, controlling for demographic and clinical covariates.
Results:
Overall, 4674 patients (mean age, 6.6 years; 49% female; 64% Hispanic; 21% Black) were evaluated across a total of 20 927 visits. Children with risk factors had higher rates of attention-deficit hyperactivity disorder, failure to gain weight, asthma, and prematurity compared with children with no risk (all P < .01). Adjusted models show a positive association between increased total number of factors and ED utilization (incidence rate ratio [IRR], 1.18; 95% CI, 1.12-1.23) and hospitalizations (IRR, 1.36; 95% CI, 1.26-1.47). There were no associations between a positive screen and time to first ED visit (hazard ratio [HR], 0.95; 95% CI, 0.85-1.06; P = .36) or hospitalization (HR, 1.15; 95% CI, 0.84-1.59; P = .40).
Conclusions:
Social risk factors were associated with increased ED utilization and hospitalizations at the patient level but were not significantly associated with time to subsequent acute care use. Future research should evaluate the effect of focused interventions on health care utilization, such as those addressing food insecurity and transportation challenges.
