Restrictions on healthcare utilization and psychological distress among patients with diseases potentially vulnerable to COVID-19; the JACSIS 2020 study

BACKGROUND: Patients with comorbidity are at higher risk of deteriorating COVID-19, but they need to access healthcare services regularly for their primary disease. This study aimed to investigate whether patients restricted healthcare utilization due to the COVID-19 pandemic and to understand the relations between restriction of healthcare utilization and psychological distress of patients with a disease potentially vulnerable to COVID-19. METHODS: Participants were a sub-sample of 6,360 individuals suffering from chronic diseases with hypertension, diabetes, respiratory diseases, cerebrovascular disease, and cancer from the nationally representative cross-sectional internet survey data of Japan. Participants reported healthcare utilization during the first state of emergency, as well as psychological distress (K6: The Kessler Psychological Distress Scale 6) in three months after the state of emergency was ended. Multivariate linear regression analyses were performed to examine the correlation between psychological distress and healthcare utilization. RESULTS: In total, 16% restrained from visiting a hospital as scheduled or canceled a doctor visit. Approximately less than 2% experienced cancellation or delay of hospitalization, treatment, or nursing-care services. After controlling for confounders, multivariate linear regression analysis showed that those who lacked medicines, experienced deteriorated health conditions, and could not visit a hospital during the state of emergency reported severe psychological distress three months later among the patients with all disease types except cancer (β = 0.10∼0.25). CONCLUSIONS: The study indicated the restriction in healthcare utilization might be a risk factor for psychological distress among patients. Careful attention to the mental status of patients, especially those who were restricted in healthcare utilization, is necessary.
