PurposeUlcerative colitis (UC) may cause many patients to miss out on important personal and professional opportunities. We therefore conducted a survey (UC-LIFE) to assess patients’ perceptions of the impact of UC on social and professional lives.Patients and methodsConsecutive unselected UC patients aged ≥18 years were recruited from 38 outpatient clinics in Spain. Patients completed the survey at home, returning it by post. The survey comprised 44 multiple-choice questions, including questions about the impact of UC on social, personal, professional, and academic activities.ResultsOf 585 patients invited, 436 (75%) returned the survey (mean age 46 years; 47% women). High proportions of patients considered their disease “sometimes”, “frequently” or “mostly/always” influenced leisure activities (65.1%), recreational or professional activities (57.6%), or relationships with relatives or friends (9.9%). Patients also reported that UC influenced their decision to have children (17.2%), or their ability to take care of children (40.7%); these percentages were higher in women and in younger patients. Overall, 47.0% of patients declared that UC influenced the kind of job they performed, 20.3% had rejected a job due to UC, 14.7% had lost a job due to UC, and 19.4% had had academic problems due to UC.ConclusionBeyond symptoms alone, UC imposes an enormous additional burden on patients’ social, professional, and family lives. This extra burden clearly needs to be addressed so that the ultimate goal of IBD treatment – normalization of patient quality of life – can be attained by as many patients as possible.
