Objective: We aimed to identify patient-level demographic and behavioral characteristics associated with higher social isolation among patients with cancer throughout the coronavirus disease 2019 (COVID-19) pandemic.
Method: Moffitt Cancer Center patients seen on or after January 1, 2015, had a last known alive vital status, a valid e-mail address, and were 18-89 years old, were emailed a survey regarding social isolation. We collected information on age, sex, race, ethnicity, marital status, smoking, self-reported cancer diagnosis, cancer treatment, and perceived life changes due to the COVID-19 pandemic. We calculated a COVID-19 risk mitigation score by summing the frequency of risk mitigation behaviors (e.g., mask wearing). Social isolation was assessed with the self-reported Patient-Reported Outcomes Measurement Information System (PROMIS) Social Isolation Short Form. Logistic regression models compared characteristics of participants reporting higher versus lower social isolation (T-scores >60 vs. ≤60).
Results: Most participants (N = 9,579) were female (59.2%), White (93.0%), and non-Hispanic (92.5%). Participants at greater odds of higher social isolation were younger (per 10 years decrease odds ratio [OR] = 1.36, 95% confidence interval, CI [1.30, 1.43]), female (vs. male OR = 1.54, 95% CI [1.36, 1.74]), unmarried (vs. married OR = 1.83, 95% CI [1.62, 2.08]), current smokers (vs. never OR = 2.38, 95% CI [1.88, 3.00]), reporting more risk mitigation behaviors (per 1 SD; OR = 1.33, 95% CI [1.24, 1.42]), and more perceived life changes (vs. little/no change; OR = 2.64, 95% CI [2.08, 3.35]).
Conclusions: We identified younger age, females, unmarried, current smokers, more risk mitigation behaviors, and more perceived life changes increased odds of social isolation for patients with cancer during the COVID-19 pandemic. This can inform identification of patients with cancer at higher risk of social isolation for targeted mitigation strategies. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
