Insights
Frequent emergency department (ED) use is common in children with cancer, with a small group accounting for most visits. Future research should focus on these frequent pediatric cancer patient ED users.
Area of Science:
- Pediatric Oncology
- Healthcare Services Research
- Emergency Medicine
Background:
- Pediatric frequent emergency department (ED) utilizers represent a significant burden on healthcare resources.
- No prior studies have specifically investigated frequent ED utilization patterns in children with cancer.
Purpose of the Study:
- To identify the characteristics and factors associated with frequent ED utilization among pediatric cancer patients.
- To understand the patterns of care received during ED visits by children with cancer.
Main Methods:
- Retrospective analysis of the Pediatric Health Information System database for ED visits in children with a malignancy diagnosis.
- Definition of frequent ED utilizers as those with >= 4 visits within 365 days of initial inpatient encounter (top 10th percentile).
- Multivariable regression analysis to identify factors associated with frequent ED utilization and assessment of ED services provided.
Main Results:
- Frequent ED utilizers accounted for 58% of all ED visits among children with cancer.
- Frequent utilization was associated with specific cancer types (acute lymphoblastic leukemia, central nervous system tumors), younger age groups (<10 years), and Hispanic ethnicity.
- A small proportion of children with cancer received no medication, laboratory, or imaging during their ED visits (11.0% for frequent vs. 12.5% for infrequent).
Conclusions:
- The emergency department (ED) plays a crucial role in the care continuum for pediatric cancer patients.
- Identifying and focusing on the subset of frequent ED utilizers is essential for future research and quality improvement initiatives in pediatric oncology care.
Background:
Pediatric frequent emergency department (ED) utilizers contribute a significant proportion of ED visits, but no studies specifically address children with cancer.
Methods:
A retrospective study of Pediatric Health Information System analyzing ED visits for children with cancer, including ED visits within 365 days from the first inpatient encounter with a discharge diagnosis code for malignancy. We defined frequent ED utilizers as those with four or more visits in the year (top 10th percentile). Patient characteristics and ED services (medications, laboratory, or imaging) for discharged children were assessed. Factors associated with being a frequent ED utilizer were examined with multivariable regression.
Results:
Frequent utilizers accounted for 58% of ED visits. Frequent utilizers differed from infrequent utilizers in terms of type of cancer; 39.3% of frequent utilizers had acute lymphoblastic leukemia (ALL) and 16.0% had central nervous system (CNS) tumors compared with infrequent utilizers (21.9% had ALL and 24.8% CNS tumors, P-value < 0.001). Frequent utilization was associated with age 5-9 years (odds ratio [OR] = 1.4, 95% confidence interval [CI] 1.2-1.6) or 1-4 years (OR = 2.1, 95% CI 1.8-2.4) or <1 year (OR = 2.2, 95% CI 1.9-2.6) compared to 15-19 years and Hispanic ethnicity (OR 1.3, 95% CI 1.1-1.5) compared to white, non-Hispanics, and urban residence (OR = 1.5, 95% CI 1.3-1.7). Few children with cancer received no medication, laboratory, or imaging during their ED visit (frequent 11.0% vs. infrequent 12.5%, P = 0.01).
Conclusions:
The ED is integral to the care provided to children with cancer. The subset of frequent utilizers should be the focus of future research and quality improvement efforts.
