Abstract

Background/aim

The patient’s perspective on the healthcare that they receive has become increasingly important in the assessment of healthcare quality, especially in chronic diseases such as inflammatory bowel disease (IBD). In this context, the questionnaire QUOTE-IBD (Quality of Care Through the Patient’s Eyes with Inflammatory Bowel Disease) was created to assess the healthcare quality from the point of view of a patient with IBD. This questionnaire does not yet have a validated Portuguese version (PT-QUOTE-IBD). We aimed to assess the acceptability, validity, and reliability of PT-QUOTE-IBD.

Patients and methods

This was an observational longitudinal unicentric study with three sequential phases: (a) translation and cultural adaptation of QUOTE-IBD that explores the Importance, Performance and Quality Impact of several dimensions of healthcare; (b) assessment of validity by correlation of the results of PT-QUOTE-IBD and visual analogue scales (VAS); and (c) assessment of the reliability of PT-QUOTE-IBD through a second administration of the questionnaire, with a minimum interval of 4 weeks.

Results

We included 114 patients with IBD (77 Crohn’s disease and 37 ulcerative colitis). Fifty-nine percent of the patients completed all the questions of QUOTE-IBD and VAS. We obtained positive and significant Pearson’s correlation coefficients between QUOTE-IBD scores and VAS for Performance and Quality Impact of Total Care and dimensions Accessibility and Information. Thirty-four (30%) patients completed the second questionnaire adequately. We obtained positive and significant Pearson’s correlation coefficients between the two questionnaires for Performance and Quality Impact of Total Care, Accessibility, Continuity of Care, Courtesy and Information, and for Performance of Cost.

Conclusion

PT-QUOTE-IBD is acceptable, valid, and reliable in the assessment of Performance and Quality Impact of Total Care, but not of all dimensions of healthcare.
