Abstract
Purpose
This review aimed to assess the measurement and reporting of time toxicity (i.e., time spent receiving care) within prospective oncologic studies.
Methods
On July 23, 2023, PubMed, Scopus, and Embase were queried for prospective or randomized controlled trials (RCT) from 1984 to 2023 that reported time toxicity as a primary or secondary outcome for oncologic treatments or interventions. Secondary analyses of RCTs were included if they reported time toxicity. The included studies were then evaluated for how they reported and defined time toxicity.
Results
The initial query identified 883 records, with 10 studies (3 RCTs, 2 prospective cohort studies, and 5 secondary analyses of RCTs) meeting the final inclusion criteria. Treatment interventions included surgery (n = 5), systemic therapies (n = 4), and specialized palliative care (n = 1). The metric “days alive and out of the hospital” was used by 80% (n = 4) of the surgical studies. Three of the surgical studies did not include time spent receiving ambulatory care within the calculation of time toxicity. “Time spent at home” was assessed by three studies (30%), each using different definitions. The five secondary analyses from RCTs used more comprehensive metrics that included time spent receiving both inpatient and ambulatory care.
Conclusions
Time toxicity is infrequently reported within oncologic clinical trials, with no standardized definition, metric, or methodology. Further research is needed to identify best practices in the measurement and reporting of time toxicity to develop strategies that can be implemented to reduce its burden on patients seeking cancer care.
