COVID-19-Related Treatment Cancellations and Oncology Patients' Psychological Health in Nigeria.

To explore the association between COVID-19-related cancer treatment cancellations and the psychological health of cancer patients in Nigeria. We analyzed data collected from 15 outpatient cancer clinics, comprising 1,097 patients between April to July 2020. Study outcome was ten psychological impacts, including feeling down, stressed, and unable to access treatment due to COVID-19 (used as continuous and categorical variable (0-3,4-7,8+ events). The independent variable was treatment cancellations due to COVID-19 categorized as 0, 1, and 2+ cancellations. Confounders included religion, ethnicity, income, cancer diagnosis/type, and treatment received. Stata/SE.v.17 was used to perform all analyses. values of ≤0.05 were deemed statistically significant. Of the 1,097 cancer patients, 65.7% were female, with a mean age (SD) of 49.4 (13.8) years. Most patients (50.3%) reported four to seven psychological health events. Cancer patients who reported two/more treatment cancellations made up only 12.8% of the study sample but accounted for a greater proportion of psychological impacts (23.5%; <0.001). In the adjusted model, cancer patients with one treatment cancellation (Coef: 0.195, 95%CI: 0.089-0.302) and those with two/more cancellations (Coef: 0.379, 95%CI: 0.255-0.504) had a significantly higher risk of psychological health impacts than those with no treatment cancellations. More than half of our sample of primarily adult female cancer patients reported major psychological health effects due to COVID-19. Cancer patients who experienced at least one treatment cancellation had a higher risk of psychological health consequences than those who did not. The implications of our findings and how to mitigate the impact of COVID-19 on oncology service disruptions are discussed.
