Is Peer Support in Group Clinics as Effective as Traditional Individual Appointments? The First Study in Patients With Celiac Disease.

Celiac disease (CD) is common, affecting approximately 1% of the population. The cornerstone of management is a gluten-free diet, with dietetic advice being the key to aiding implementation. The aim of the study was to assess group clinics in comparison with traditional individual appointments. Patients with a new diagnosis of CD, confirmed histologically, were prospectively recruited over 18 months in Sheffield, United Kingdom. Patients received either a group clinic or traditional one-to-one appointment, led by a dietitian. Quality-of-life questionnaires were completed at baseline, as well as biochemical parameters being recorded. Patients were followed up at 3 months, where adherence scores were assessed as well as biochemical parameters and quality of life questionnaires being completed. Sixty patients with CD were prospectively recruited and received either an individual (n = 30) or group clinic (n = 30). A statistically significant reduction in tissue transglutaminase was noted following group clinics (mean 58.5, SD 43.4 U/mL vs mean 13.2, SD 5.7 U/mL, P < 0.01). No significant differences in baseline and follow-up biochemical parameters between one-to-one and group clinics were noted. At follow-up, there was no statistically significant difference between mean gluten-free diet adherence scores (mean 3.1, SD 0.4 vs mean 3.1, SD 0.7, P = 0.66) between one-to-one and group clinics. This first study assessing group clinics in CD demonstrates they are as effective as traditional one-to-one clinics, with the added benefits of peer support and greater efficiency, with an estimated 54% reduction of dietetic resources.
