Background: Coronavirus disease 2019 (COVID-19) epidemic has brought significant changes to patients of chronic pain. Social distancing limited their access to hospital. The aim of this study was to investigate the impact of the changes in chronic pain patients during the COVID-19 pandemic.
Methods: Patients of chronic pain from 23 university hospitals in South Korea were participated. The anonymous survey questionnaire consisted of 25 questions on the following aspects of patients: demographic data, diagnosis, visiting frequency of hospital, exercise time, outing time, sleeping time, weight change, nervousness and anxiety, depression, interest or pleasure, fatigue, daily life difficulties, and self-harm thoughts. Additionally, depression severity was evaluated using the Patient Health Questionnaire-9 (PHQ-9). Logistic-regression analysis was used to investigate the relationship between increased pain and the patient¡¯s factors.
Results: A total of 914 patients from 23 university hospitals completed the survey. The 35.9% of patient decreased their visits to hospital mostly due to COVID-19. 200 patients said their pain level has worsened since COVID-19, which was more prominent in complex regional pain syndrome (CRPS). Noticeable post-corona changes such as exercise time, day out hours, sleep patterns, mood and weight affected chronic pain patients. Depression severity came out more significantly in CRPS patients. The total PHQ-9 average score of CRPS patients was 15.5, corresponding to the major depressive orders. The decrease in the patient\'s visit frequency, decrease in exercise time, decrease in sleep time and increased depression were significantly associated with increasing pain of the patients.
Conclusions: During COVID-19 pandemic, decreased exercise time and sleep time and increased the depression were significantly associated with increasing patients¡¯ pain.
