Emotional distress and future healthcare utilization in oncology populations: A systematic review

Abstract

ObjectiveEmotional distress has been correlated with greater healthcare utilization and economic costs in cancer; however, the prospective relationship between positive distress screens and future healthcare utilization is less clear. Taken together, there is a critical need to synthesize studies examining the prospective relationship between emotional distress and future healthcare use to inform distress management protocols and motivate institutional resource allocation to distress management. The aim of the systematic review is to explore the relationship between emotional distress, measured via validated emotional distress questionnaires, and subsequent healthcare utilization in patients diagnosed with cancer.MethodsA systematic search of seven databases was conducted on 29 March 2022 and updated 3 August 2023. Eligibility criteria were: (1) peer‐reviewed, (2) quantitative or mixed methods, (3) adults (≥18 years) diagnosed with cancer, (4) cancer distress questionnaire(s) completed prior to healthcare utilization, and (5) written in English. Exclusion criteria included: (1) non‐emotional aspects of distress (i.e., spiritual or physical distress), (2) healthcare utilization characterized via economic or monetary variables, and (3) caregiver or non‐cancer populations.ResultsNineteen peer‐reviewed articles were included in the review. There was significant heterogeneity in emotional distress instruments and type of healthcare utilization used. Most studies examining general distress or anxiety found that increased distress was predictive of greater future healthcare utilization.ConclusionThe results suggest that individuals with higher levels of general distress and anxiety are at increased risk for future healthcare utilization.
