title: Clinical field testing of an enhanced-activity intervention in hospitalized children with cancer.
abstract: This prospective, two-site, randomized, controlled pilot study assessed the feasibility of an enhanced physical activity (EPA) intervention in hospitalized children and adolescents receiving treatment for a solid tumor or for acute myeloid leukemia (AML), and assessed different statistical techniques to detect the intervention's sleep and fatigue outcomes. Twenty-nine patients (25 with a solid tumor and 4 with AML) participated. Data were collected from actigraph; patient, parent, and staff nurse reports of patient fatigue; parent sleep diaries; and patient charts. The intervention was successfully implemented 85.4% of the scheduled times. We used two different statistical methods to analyze the longitudinal data. Using an ANOVA model, sleep was significantly more efficient in the experimental arm than in the control arm when daily differences from baseline sleep efficiency values were averaged and compared (F=4.17, P=0.053). However, in a mixed model (repeated measures) analysis, sleep duration (F=0.54, P=0.47) and sleep efficiency (F=0.04, P=0.85) were not seen to differ between study arms. We conclude that an inpatient intervention of EPA can be delivered to children and adolescents receiving chemotherapy. Our findings identify design and statistical considerations for a future effectiveness study of the EPA intervention in hospitalized pediatric oncology patients.
