Hospital Use in the Last Year of Life for Children With Life-Threatening Complex Chronic Conditions

Abstract

Background and objectives: Although many adults experience resource-intensive and costly health care in the last year of life, less is known about these health care experiences in children with life-threatening complex chronic conditions (LT-CCCs). We assessed hospital resource use in children by type and number of LT-CCCs.

Methods: A retrospective analysis of 1252 children with LT-CCCs, ages 1 to 18 years, who died in 2012 within 40 US children's hospitals of the Pediatric Health Information System database. LT-CCCs were identified with International Classification of Diseases, 9th Revision, Clinical Modification codes. Using generalized linear models, we assessed hospital admissions, days, costs, and interventions (mechanical ventilation and surgeries) in the last year of life by type and number of LT-CCCs.

Results: In the last year of life, children with LT-CCCs experienced a median of 2 admissions (interquartile range [IQR] 1-5), 27 hospital days (IQR 7-84), and $142 562 (IQR $45 270-$410 087) in hospital costs. During the terminal admission, 76% (n = 946) were mechanically ventilated; 36% (n = 453) underwent surgery. Hospital use was greatest (P < .001) among children with hematologic/immunologic conditions (99 hospital days [IQR 51-146]; cost = $504 145 [IQR $250 147-$879 331]) and children with ≥3 LT-CCCs (75 hospital days [IQR 28-132]; cost = $341 222 [IQR $146 698-$686 585]).

Conclusions: Hospital use for children with LT-CCCs in the last year of life varies significantly across the type and number of conditions. Children with hematologic/immunologic or multiple conditions have the greatest hospital use. This information may be useful for clinicians striving to improve care for children with LT-CCCs nearing the end of life.

Multivariable analysis of hospital days and costs for children in the last year of life, by type and number of LT-CCCs. Shown are adjusted rate ratios and 95% confidence intervals for hospital resource use by type and number of LT-CCCs. For each type of LT-CCC, the reference group is the absence of that particular condition. For the number of LT-CCCs, the reference group is 1 LT-CCC. Rate ratios are adjusted for demographic (age, race/ethnicity, insurance type) and clinical (mechanical ventilation, surgery, new medical technology) characteristics.
