Abstract
PURPOSE: Patients with pediatric acute lymphoblastic leukemia (ALL) are at risk for impaired physical function from treatment. Early physical therapy (PT) may improve physical function and health in children with ALL, yet little is known about PT utilization in this population. METHODS: Leveraging the Premier Healthcare Database, we conducted a cohort study including participants hospitalized with ALL at age 0-21 years from January 1, 2010, through March 31, 2017. A generalized mixed linear model assessed sociodemographic and clinical variables associated with receiving PT within 1 year of first hospitalization. RESULTS: Among 5,488 pediatric ALL patients from 330 hospitals (median age 7 years, interquartile range = 4-14 years), only 27.2% overall and 58.9% with neuromuscular conditions received PT within a year of first ALL admission. In multivariable analysis, patients more likely to receive PT were age 10-14 years (odds ratio [OR] = 1.46; 95% CI, 1.20 to 1.76) or 15-21 years (OR = 1.66; 95% CI, 1.36 to 2.02) versus 0-4 years and Hispanic (OR = 1.27; 95% CI, 1.04 to 1.56) versus White. Patients less likely to receive PT were treated by a nonhematology/oncology pediatric (OR = 0.56; 95% CI, 0.46 to 0.70) or adult (OR = 0.50; 95% CI, 0.38 to 0.65) specialist versus a pediatric hematologist/oncologist and treated at a nonteaching hospital (OR = 0.53; 95% CI, 0.36 to 0.79) versus a teaching hospital. CONCLUSION: Only 27.2% of pediatric ALL patients overall and 58.9% with neuromuscular conditions receive inpatient PT within a year of first ALL admission. Interventions to increase inpatient PT services to pediatric ALL patients and address disparities in PT utilization may improve the physical function and long-term health of survivors.
