BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) are chronic immunoinflammatory diseases that place a considerable burden on patients, their families, and society. Quality of care plays an important role for patients. A questionnaire to measure quality of care through the eyes of patients with inflammatory bowel disease (QUOTE-IBD) has been designed and validated specifically for the English language and culture. The objective was to translate the QUOTE-IBD into Spanish and to determine its validity in patients with IBD.

METHODS: This is a prospective study in 2 phases: first, translation and validation of the Spanish QUOTE-IBD. Translation was based on the validated QUOTE-IBD. Second, once the complete translation was finished, comprehension of the items was assessed with a specific questionnaire in a reduced number of patients. Criterion validity was assessed with the Pearson's correlation coefficient between scores of the QUOTE-IBD and visual analog scales (VAS). In order to analyze the reproducibility of the Spanish QUOTE-IBD, the questionnaire was completed by stable patients twice, with a span of time of at least 4 weeks.

RESULTS: A total of 103 patients (CD: 61, UC: 42) were included in the study. Pearson's correlation coefficient between total care Spanish QUOTE-IBD and VAS of health care items was 0.34 (P < 0.001). Correlations among all 6 care dimensions score of Spanish QUOTE-IBD and VAS were statistically significant (P < 0.01). Results of first and second administration of total care and dimensional care scores of Spanish QUOTE-IBD in 46 stable patients were not different.

CONCLUSIONS: The Spanish QUOTE-IBD has proved to be a valid instrument to measure the quality of health care for patients with CD and UC.
