Comparison of Patients' and Doctors' Reports on Health-related Quality of Life in Celiac Disease

Objective: To investigate whether implementation of a celiac disease (CD)-specific health-related quality of life (HRQOL) questionnaire would add value to CD follow-up visits; we compared patients' self-reported CD-specific HRQOL with the physician's report provided during a regular CD follow-up visit in children and young adults. Methods: A cross-sectional study in the control group of a study on self-management in CD (CoelKids). Eligible patients had CD for ≥1 year and were 25 years or younger. They completed a CD-specific HRQOL questionnaire (CDDUX) after their regular follow-up visit. Their physicians were unaware of the present study's objectives or self-reported HRQOL. Primary outcome: agreement between physician-reported and self-reported HRQOL. Secondary outcomes: patient variables predicting a discrepancy between reports, or a lower HRQOL. Results: Physician-reported HRQOL was available in 70 of 78 enrolled patients. The self-reported and physician-reported HRQOL were concordant in 30 of 70 (K=0.093), 6 of them had a poor self-reported HRQOL. Reports were discrepant in 40 of 70; all 40 self-reported a poor HRQOL. Discrepancies occurred more frequently in patients with a disease duration <9 years (32/40 with discrepant reports were diagnosed <9 years ago vs 17/30 with no discrepancy, P<0.001) and in females (35/40 with discrepant reports were girls versus 16 of 30 with no discrepancy, P=0.001). Both factors were predictors of a poorer HRQOL. Conclusions: During regular CD follow-up visits, physicians did not report a poor HRQOL in 40 of 46 children and young adults with a poor self-reported HRQOL. This is consistent with previous studies examining other chronic diseases and supports the implementation of self-reported CD-specific HRQOL measurements in CD follow-up visits.
