Impact of the Coronavirus Disease Pandemic on Health-Related Quality of Life of Patients with Inflammatory Bowel Disease.

BACKGROUND: To learn from the crisis caused by the coronavirus disease (COVID-19) pandemic and be prepared for future pandemics, it is important to investigate the impact of this period on the wellbeing of patients with inflammatory bowel disease (IBD). AIMS: To describe the health-related quality of life (HRQoL) and disease control of IBD patients during the first wave of the COVID-19 pandemic in The Netherlands. METHODS: Between March 17 and July 1, 2020, patients aged 18 years and older with IBD from the Erasmus MC (Rotterdam, The Netherlands) were invited to complete online questionnaires at week 0, 2, 6 and 12. The Inflammatory Bowel Disease Questionnaire (IBDQ), the Inflammatory Bowel Disease Control-8 (IBD-control-8) and the numeric rating scale on fatigue were used. The evolution of the different outcomes over time was measured using mixed models. RESULTS: Of 1151 invited patients, 851 patients (67% CD and 33% UC or IBD-U) participated in the study (response rate 74%). No relevant changes in total scores were found over time for the IBDQ (effect estimate 0.006, 95% CI [- 0.003 to 0.015]) and IBD-control-8 (effect estimate 0.004, 95% CI [0.998-1.011]). There was a slight, increasing trend in fatigue scores over time (effect estimate 0.011, 95% CI [0.004, 0.019]). CONCLUSIONS: This first lock down due to the COVID-19 pandemic in The Netherlands did not impact on the HRQoL and disease control of patients with IBD. Up to date information may have contributed to a stable HRQoL in IBD patients even in an extreme period with restrictions and insecurities.
