In this study, the prevalence of anxiety caused by COVID-19 pandemic and the risk and protective factors contributing to psychological stress in patients with RMDs who were using immunosuppressive drugs were investigated. Female sex was a risk factor for anxiety in the patients taking immunosuppressive drugs as well as in the control group. In addition, anxiety levels of patients who took immunosuppressive drugs were significantly higher than the control group, whereas anxiety was lower in those with higher education levels. Based on the BAI scores, 16.5% patients showed moderate to severe anxiety symptoms.
COVID-2019 is a pandemic and pandemics have various psychological effects on humans, including anxiety [22]. During the influenza epidemic (influenza A H1N1v), approximately 10% and 30% of the population had high or severe anxiety [17]. In a study conducted on the general population on the COVID-19 pandemic in China, 53.8% participants rated the psychological effect of the pandemic as moderate or severe, and 28.8% reported moderate to severe anxiety symptoms [15].
Sensational popular media titles, lack of information, and incorrect information have shown to increase the health concerns and phobias [23]. Television (82.8%) and the Internet (13.1%) were the primary information channels during the initial stage of the COVID-19 pandemic. Most participants (76.6%) were aware about the number of cases, advice on prevention, and warnings for those with chronic diseases. However, it is believed that this information, the accuracy of which is controversial, can lead to an increase in patient anxiety levels.
A guideline has stated that it is important to medically and psychologically prepare the health systems and general public if widespread transmission occurs during a pandemic [24], and it is recommended to identify high-risk groups based on the sociodemographic information for early psychological intervention [15]. The sociodemographic data in this study have shown that women who take immunosuppressive drugs have a higher level of anxiety. This result supports the extensive epidemiological studies reporting that women are at a higher risk of anxiety [25-27].
In a study conducted on the general population in China, it was found that students experienced a higher level of anxiety and psychological impact due to the pandemic [15]. Schools of all levels have been indefinitely closed in Turkey as well as the rest of the world. In this study, there were no significant differences in terms of anxiety based on occupational groups including students. During pandemics, educational authorities should develop online portals and web-based applications for courses and other teaching activities [28]. Although schools are closed in Turkey, many teaching activities continue online. As the younger population is more familiar with smartphone applications [29], they are able to continue their education. It is believed that this may be the reason why high levels of anxiety have not been detected in the younger individuals.
A recent study in China found that the general population without formal education was more likely to be depressed during the pandemic [15]. In another study that evaluated population-based psychological morbidity after the SARS epidemic, there was a significant correlation between education level and psychiatric morbidity, and it was recommended to divide the population into sections based on the level of education to increase crisis communication [10]. In this study, anxiety was lower in those with higher education levels. Therefore, it may be recommended to provide audio–visual information with simple language, when required, to support patients based on their education levels during the pandemic.
In this study, anxiety was found in 38.6% patients. The prevalence of anxiety in patients with RA, SpA, vasculitis, FMF, and connective tissue disease were 39.4%, 16%, 36.7%, 65.4%, and 35.5%, respectively. A study that evaluated anxiety disorder in patients with rheumatic disease, anxiety was reported in 44.4% patients. The prevalence of anxiety in patients with RA, primary Sjögren syndrome, systemic lupus erythematosus, and Behçet syndrome were reported to be 52%, 50%, 41%, and 38%, respectively [30]. The prevalence of anxiety in the SpA group was similar to the previous study [31], whereas the prevalence of anxiety in the FMF patient group was higher than the other groups. This suggests that FMF patient group may have been more affected by social isolation caused by the quarantine process due to younger age and being more active. Similarly, in studies that compared patients with inflammatory rheumatic diseases with healthy controls, anxiety was higher in the patient group [32-39].
In this study, the prevalence of anxiety was 18.9% in the control group, and there was a significant difference in anxiety levels between the patient and controls groups. In pre-pandemic studies, the prevalence of anxiety in healthy controls is significantly lower than that found in this study (6.6% - 9.6%) [31,35,36]. Although the control group had increased anxiety levels, the difference was significant, suggesting that our patients had high anxiety. It may be recommended that health authorities consider providing online or smartphone-based psychoeducation and psychological interventions to reduce the risk of virus infection via face-to-face treatment. In addition, they should be informed individually by the clinic where they are followed, and it should be ensured that they trust the treatment team.
This study has several limitations. Given the inability to meet face-to-face and time sensitivity of the COVID-19 pandemic, data were collected by contacting patients on the phone. The reported anxiety levels may not always correspond to the assessment by mental health professionals. Similarly, patients may have given socially desirable responses regarding their anxiety levels. Finally, a patient was diagnosed with COVID-19 and had no relatives around her/him. Therefore, surveys may have been conducted early. Despite the above limitations, this study, which was conducted on patients with inflammatory RMDs who were using immunosuppressive drugs 2 weeks after the appearance of COVID-19 in Turkey, was considered to be the first that evaluated the effects of pandemic on anxiety. As the COVID-19 pandemic continues to spread, our results are expected to provide recommendations on the development of psychological support for patients in the risk group who are taking immunosuppressive drugs and in priority areas in Turkey and in other countries affected by the pandemic.
