Abstract
Background
Given the increasing health concerns for patients with inflammatory bowel disease (IBD), amidst the COVID-19 pandemic, we investigated the impact of the pandemic on the anxiety and behavioral changes in Japanese patients with IBD.
Methods
We analyzed 3032 questionnaires from patients with IBD, aged 16 years or older visiting 30 hospitals and 1 clinic between March 2020 and June 2021. The primary outcome was the score of the anxiety experienced by patients with IBD during the pandemic.
Results
Participants reported a median age of 44 years; 43.3% of the patients were women. Moreover, 60.6% and 39.4% were diagnosed with ulcerative colitis and Crohn’s disease, respectively, with a median disease duration of 10 years. Participants indicated an average of disease-related anxiety score of 5.1 ± 2.5 on a ten-point scale, with a tendency to increase, 1 month after the number of infected persons per population increased. The top three causes for anxiety were the risk of contracting COVID-19 during hospital visits, SARS-CoV-2 infection due to IBD, and infection by IBD medication. Factors associated with anxiety were gender (women), being a homemaker, hospital visit timings, mode of transportation (train), use of immunosuppressive drugs, and nutritional therapy. Most patients continued attending their scheduled hospital visits, taking their medications, experienced the need for a family doctor, and sought guidance and information regarding COVID-19 from primary doctors, television, and Internet news.
Conclusions
Patients with IBD experienced moderate disease-related anxiety due to the pandemic and should be proactively informed about infectious diseases to relieve their anxiety.

Introduction
After the rapid spread of the novel coronavirus disease 2019 (COVID-19), the World Health Organization declared it a global pandemic on March 11, 2020 [1]. Increasing evidence indicates that older and immunocompromised patients, and those with chronic diseases, are at a higher risk of contracting severe or fatal COVID-19 [2].
Inflammatory bowel disease (IBD) comprises two major disease types—ulcerative colitis (UC) and Crohn's disease (CD), which occur at a relatively young age with a high incidence rate between late teens and early 30s [3]. Patients with IBD endure the disease throughout their lives. Therefore, it is important to maintain patients’ quality of life (QOL) by focusing on treatment alongside their overall life. Owing to the COVID-19 pandemic, global citizens, including those in Japan, are restricting unnecessary movement outside the house, and many patients with stable symptoms are postponing medical visits or being prescribed medication over the phone [4, 5].
Patients with IBD experience repeated relapses; subsequently, they undergo major dilemmas between the threat of contracting COVID-19 by visiting the doctor and the anxiety of disease progression by postponing the visit [6, 7]. Additionally, steroids, immunomodulators, and biologics that influence the risk of COVID-19 are often used in the treatment of patients with IBD, but the extent of their influence is still under investigation. Therefore, it is possible that these patients are unaware about how to obtain COVID-19-related information and may have voluntarily reduced or withdrawn their medication. Moreover, since health-care providers were not entirely familiar with COVID-19 themselves, it is unclear how much information was provided to the patients regarding daily life practices and risks related to COVID-19. Several questionnaire surveys on the anxiety of patients with IBD during the pandemic demonstrated the impact of COVID-19 on health and psychological well-being alongside the increasing concern regarding the risk of contracting COVID-19 and medication continuation [6,7,8,9,10,11,12,13].
Meanwhile, significant difference in these factors owing to regional and national characteristics, and medical conditions have been indicated. However, no such large-scale survey has been conducted in Japan. Therefore, this study conducted a questionnaire survey to investigate the anxiety and behavioral changes among Japanese patients with IBD during the COVID-19 pandemic. This study was referred to as the Japan COVID-19 Survey and the Questionnaire for Inflammatory Bowel Disease (J-DESIRE).
Methods
Patient recruitment
At each recruiting institution, the attending physician personally explained the aim and contents of the survey to each patient with IBD, and asked them to complete a paper-based questionnaire related to COVID-19, after obtaining their written informed consent. Within 2 weeks of distribution, the completed questionnaires were sent to the Department of Gastroenterology, at the Sapporo Medical University Hospital. The participant recruitment period was between March 2020 and June 2021.
Questionnaire
First, the co-authors developed the questionnaire by referring to previous reports [8, 14] and adding questions that they thought would be useful for gathering information regarding anxiety of IBD patients. After that, Japan IBD COVID-19 task force members (HN, TM, MM, HI, KM, NO, SI, FH, and TH) conducted internal evaluations several times to complete the questionnaire. The questionnaire consisted of six major domains, some of which were rated on a ten-point visual analog scale (VAS) and focused on the impact of COVID-19 on anxiety related to IBD, disease activity, medical examination, IBD medication, and prevention of infection (Questionnaire in the Supplementary Material). The reason for using the VAS in this study was to ensure that patients could show their feelings easily and the difference could be measured. Additionally, we collected and assessed data regarding demographics, socioeconomic status, IBD diagnoses, comorbidities, and current IBD treatment. The primary outcome was the VAS score for disease-related anxiety during the pandemic [Q1. (1) How much anxiety did you feel about your disease due to the outbreak of SARS-CoV-2?]. This study protocol was approved by the institutional review board of Sapporo Medical University and registered publicly on the UMIN registration (No. UMIN000041191).
Statistical analysis
Descriptive statistics were computed using mean and standard deviation (SD) for continuous variables—ten-point VAS scores—and the proportion for categorical variables.
Two or more continuous variables groups were compared using Student’s t test or analysis of variance (ANOVA). Pearson's correlation was used to examine the relationship between the number of infections per population (in the current month, 1 month ago, and 2 months ago) and anxiety scores. Univariate and multivariate analyses were exploratorily performed using general linear models to assess the factors associated with the primary outcome (VAS score of disease-related anxiety) with/without adjusting for potential confounding factors. We calculated variance inflation factor (VIF) to evaluate multicollinearity for included covariates, and considered it acceptable if VIF < 5 for each coefficient to be interpreted.
Statistical significance was set at P < 0.05. All analyses were performed using SPSS version 25 (IBM, Armonk, NY, USA). Due to the descriptive and exploratory nature of this epidemiological study, we employed the convenience sampling method for participant recruitment; therefore, sample size was not calculated using power tests. Based on the current sample size and the parameters obtained a posteriori (standard deviation: 2.5), a difference of 1.3 can be detected in the VAS scores for disease-related anxiety between the two equal-size groups with a probability of 91% (Student's t test). This probability is 81%, if the ratio of the group size is 1:3. No imputations were performed for missing data, and those with complete data for entered items were included in the univariate and multivariate analyses, respectively.
Results
Demographics and clinical characteristics
A total of 3790 questionnaires were distributed with a return rate of 80.4% (3049/3790). Of these, 17 were excluded because of withdrawal of consent. Finally, 3032 questionnaires were analyzed. Tables 1 and 2 present the participants’ demographic data. Descriptive analyses revealed that 43.3% were women and participants’ median age was 44 years (ranging: 16–92 years) (Fig. S1). Moreover, 60.6% and 39.4% had been diagnosed with UC and CD, respectively. The analysis of patients' hospital visits revealed that only 7.1% of the patients visited community doctors near their homes, while 92.9% of the patients visited a specialized IBD facility. The study period spanned from the middle of the second pandemic wave to the end of the four waves of COVID-19 in Japan (Fig. S2). Fig. S3 presents the number of questionnaires collected by region.
Changes in and contents of patients’ anxiety during COVID-19 pandemic
The primary outcome was the VAS score for disease-related anxiety during the COVID-19 pandemic (Q1 [1]). During this pandemic, the mean VAS score was 5.1 ± 2.5, which indicated moderate anxiety (Fig. 1A). No difference was observed between the VAS scores on anxiety among various Japanese regions. Figure 1B presents the changes in VAS anxiety scores alongside the changes in COVID-19 waves. Pearson's correlation coefficients indicated an increasing tendency in anxiety scores, a month after the number of infected persons per population increased; however, no significant correlations were found between the VAS scores for anxiety and the number of infected persons per population in the relevant month.
Univariate and multivariate analyses reported that gender (women), homemaker, arrival time at hospital from home, and usual means of commuting to the hospital (train) were significant factors for the VAS anxiety scores (Table 3). Similarly, the use of IBD medications, such as steroids, budesonide, thiopurine, tofacitinib, infliximab, ustekinumab, vedolizumab, and nutritional therapy were identified as significant factors (Tables 3, Table S1, Fig. 2A and 2B). In addition, both visiting the hospital and receiving a medical examination as scheduled and postponing or cancelling the examination significantly affected patients’ anxiety score. Interestingly, multivariate analysis demonstrated patients' anxiety scores decreased significantly after the start of vaccination (March 2021).
Further, participants were asked about the contents of their anxiety (Fig. 3). The most common concerns reported were “I am worried about visiting a hospital because of the fear of contracting COVID-19 (56.2%),” “I am worried that my disease itself may increase the possibility of contracting COVID-19 (55.6%),” “I am worried that my medication might increase the possibility of contracting COVID-19 (33%),”, and "I am worried that I might pass on COVID-19 to others (25%)". Most of participants reported abdominal symptoms before the pandemic (Fig. S4), and their symptoms rarely worsened after the pandemic (Fig. S5). They believed that the pandemic did not strongly influence their own lives (Fig. S6).
Changes in medical visits during the COVID-19 pandemic
The survey results for medical visits revealed that about 90% of the patients went to the hospital and received treatment as scheduled. Moreover, among the 9.9%, who could not visit the hospital or postponed their visit, 53.1% voluntarily postponed their visits, while 45.4% were advised to do so by their physicians. The usual interval between hospital visits was 1 month and 2–3 months for 26% and 73.5% of the patients, respectively (Table 1). The time taken to visit the hospital was < 30 min, 1–2 h, and > 3 h for 50.2%, 47.7%, and 2.1% patients, respectively (Table 1). Amidst the pandemic, only 5.5% of patients changed their mode of transportation to the hospital. For the question Q2 on medical visits (Medical visits. [5]) inquiring “How do you feel about the need for a family doctor specializing in IBD amidst an infectious disease pandemic, such as COVID-19?”, 32% of the participants reported experiencing a strong need (score 10), with 69% of the participants reporting a score of ≧ 6 points (Fig. 4).
IBD medications during the COVID-19 pandemic
-
(a)
The risk of IBD medications
Regarding the history of steroid use among the patients, 56.3%, 27.8%, and 8.9% had previously used, never used, and were currently using steroids, respectively.
Regarding the question whether steroids, immunomodulators, JAK inhibitors (tofacitinib), and biologics increase the risk of SARS-CoV-2 infection, about 50% of participants answered “I am not sure”. Participants determined the risk of infection related to these medications through several information sources (Fig. S7-9).
-
(b)
Change in IBD treatments
During the pandemic, 97.5% of the patients continued oral medication and injections as recommended by physicians, 1.9% reduced the dose of medication, and 0.6% discontinued medication. The reasons for the patients’ reduced dose or discontinued medication were (1) stable abdominal symptoms (38.4%), (2) instructions from the attending physicians (31.5%), and (3) a higher risk of contracting infection due to medication (21.9%).
-
(c)
Explanation of the continuation of IBD medication by physicians
A total of 42.6% received an explanation about the continuation of medication from their physicians, while 57.4% did not. Patients were highly satisfied with receiving the explanation (median VAS score is 10) (Fig. S10). Regarding anxiety after hearing the explanation, 45.7% responded that their anxiety remained the same; however, most of them scored < 5 on the VAS, suggesting that the explanation improved their anxiety (Fig. S11). Meanwhile, 91.5% of those who did not receive an explanation, did not ask their physicians about continuing medication.
Information regarding prevention of COVID-19
Of the patients, 35.6% received information about the prevention of COVID-19 from their physicians, while 64.4% did not. Most patients were satisfied with the explanation from their physicians (median VAS score: 8) (Fig. S12 and S13), while 89.2% of the patients who did not receive an explanation did not intend to ask their physicians, and 10.2% wanted to ask them but could not.
Endoscopic examination
Of the patients, 48.5% underwent the examination as scheduled, while 11.4% postponed it and 1.5% did not continue it. Among the patients who postponed or stopped endoscopic examination, 72.3% answered that their physicians asked them to refrain from the examination.
Behavioral changes before and after the start of vaccination
We examined the behavioral changes before (February 2021) and after the start of vaccination (March 2021). Only the item "endoscopic examination" showed significant changes in behavior before and after the start of vaccination. However, we have not found any significant change for other items (means of transportation, visiting the hospital, reasons for postponing the visit, examinations, and continuation of treatment) (Table S2).
Discussion
We conducted a large-scale survey among 3032 adult Japanese patients with IBD to demonstrate the impact of COVID-19 on these patients’ anxieties and health behaviors. The primary outcome was to evaluate patients’ disease-related anxiety during the COVID-19 pandemic using the VAS scores. We found that patients with IBD reported moderate disease-related anxiety; however, their VAS scores fluctuated with the COVID-19 waves. Additionally, the VAS score for anxiety tended to be associated with the number of infected people per population a month ago. Subsequently, the VAS scores for anxiety tended to increase one month after the number of infected persons per population increased. There were no significant regional differences in the VAS scores for anxiety in Japan. Univariate and multivariate analyses revealed that being a woman, a homemaker, hospital visit time and commuting to the hospital by train were factors associated with anxiety. We also identified the use of several IBD drugs, visiting the hospital and receiving a medical examination as scheduled, and postponing or cancelling the examination as factors related to patients’ anxiety. Of note, patients' anxiety scores decreased significantly after the start of vaccination.
Over 30% of the participants reported a strong need for community-based gastroenterologists during a pandemic situation similar to COVID-19. The current survey results of Japanese patients with IBD provide information regarding disease-related anxiety and behavioral changes during COVID-19 as well as the clinical issues encountered in the future management of patients with IBD.
The pandemic has greatly impacted the management of patients with IBD considering the enhanced risk of severe disease and death by COVID-19 with age and existing chronic disease [2]. Physicians are primarily concerned regarding the risk of COVID-19 in patients with IBD while determining their follow-up term, medical treatment course, and endoscopic assessment [15,16,17,18,19]. Further, many patients with IBD may lack information on COVID-19, and subsequently may be burdened by serious health concerns and anxiety.
This survey primarily focused on the disease-related anxiety in patients with IBD patients during the COVID-19 pandemic. The VAS scores revealed that participants experienced moderate anxiety, with the major concerns being the fear of (1) visiting a hospital due to the risk of contracting COVID-19 and (2) the disease itself increasing the risk of contracting COVID-19, consistent with previous reports [10,11,12]. Furthermore, we identified several factors associated with patients’ anxiety. Women reported higher anxiety scores than men and this tendency was consistent with that of the general population. Several studies have indicated that women are at a higher risk of developing anxiety and/or depressive symptoms [20, 21]; therefore, a pandemic situation might intensify their anxieties. Furthermore, the higher anxiety scores observed in unemployed and part-time workers may arise from concerns about their living costs if they contract COVID-19. Our results regarding the association of anxiety with the use of IBD medication and nutritional therapy have been investigated with other studies, which suggest that patients with IBD tend to overestimate the risks of biologics, tofacitinib, and thiopurine, despite contradictory evidence that there is no significant increase in the risk associated with these agents, except for when used in combination therapy [22, 23]. The Ministry of Health, Labour and Welfare has published the Japan IBD Task Force’s guidelines on patient care and medications for Japanese physicians on the websites of the Japan IBD research group and the Japanese Society for Inflammatory Bowel Disease [24]. However, the current survey results suggest that the explanation provided by doctors regarding the risks associated with drugs to patients may be inadequate. In Japan, nutritional therapy is provided in combination with several drugs. Accordingly, the higher anxiety levels among patients receiving nutritional therapy may result from high levels of concern about their nutritional status. Consistent with several studies on the concern regarding the risk of IBD medication [25, 26], our results revealed the importance of providing current and accurate information on COVID-19 to help mitigate medication-related anxiety and prevent inappropriate medication cessation. Regarding hospital visit, despite the pandemic situation, about 90% of the patients visited the hospital and received treatment on a regular basis. This result is not surprising since most of participants were attending a specialized IBD facility. In some Japanese regions, fewer physicians and medical staff are familiar with and experts in IBD treatment, thus, forcing many patients to go to specialized core hospitals. Therefore, most patients reported long duration for their hospital visit despite fear of contracting COVID-19; moreover, the impact of COVID-19 also increased patients’ need for a family doctor. Additionally, based on data regarding the behavioral changes before and after the start of vaccination, we found significantly behavioral changes in "endoscopic examination" before and after the start of vaccination. On the other hand, we did not find any significant changes for other items. The results suggest that physicians did not schedule endoscopic examinations, such as surveillance for patients with quiescent IBD, prior to the start of the vaccination during COVID-19 pandemic situation.
The results found that participants used their own thoughts, the internet, TV, and attending physicians as information sources, to evaluate the risk of infection from IBD itself and the corresponding medication. In a normal setting, patients with IBD ask physicians for information regarding IBD treatment and clinical problems. However, in this survey, Japanese patients with IBD primarily sought guidance, and information regarding COVID-19 from TV or Internet news. Several other surveys observed similar behavior [6, 7, 9]. The Japan IBD Task Force developed QR code to circulate a PDF file among patients with IBD, regarding COVID-19-related information required by these patients [27]. The results of this survey may reflect the limited number of patients who accessed this information, although it remains unclear whether they might feel that IBD physicians were not familiar with COVID-19. Combined with existing findings, the current survey data strongly suggest the need for a proactive, and interactive approach to IBD patient management.
This study has several limitations. First, the current study result interpretations are limited, as the primary outcome is measured only by a single item and the cross-sectional design restricts the interpretations of long-term effects of the pandemic. Future studies should employ a longitudinal study design using validated questionnaires. Second, since the sample only included patients with IBD over 16 years of age, we could not examine the anxiety among children with IBD and their parents. Third, the lack of a control group restricted comparisons of our findings with other adult populations’ findings. Fourth, we did not conduct a questionnaire survey during the fifth COVID-19 wave in Japan to avoid extending the study period, as we believe it was necessary to accumulate and analyze our data as soon as possible. Fifth, this survey was conducted within many specialized IBD centers. This particular setting may have influenced the need for community-based gastroenterologists.
In conclusion, we performed a large-scale data analysis to examine the effects of the COVID-19 pandemic on the anxiety and behavioral changes in Japanese patients with IBD. Subsequently, we reported the factors affecting anxiety, as well as the problems in the future management of patients with IBD. Future researchers and health-care professionals should continue to proactively inform patients about infectious diseases including COVID-19 and provide accurate corresponding information related to IBD care, thereby relieving patient anxiety as much as possible.
