Nelson M, Mendoza N, McGough N. A survey of provision of dietetic services for coeliac disease in the UK. J Hum Nutr Diet. 2007; 20: 403-411.PubMed ID: 17845374
?Specific areas of interest included:
- Factors associated with the level and range of dietetic input to celiac patients
- The grade of the dietitian providing services to celiac patients
- The training of the dietitian providing services
- Identification of guidelines used for management of celiac patients
- Modes of teaching used
- Impact of membership to British Dietetic Association and Coeliac UK
- Assessment of engagement of Coeliac UK with dietitians.
- Birmingham and Black Country
- East Midlands
- North East
- North Staffordshire
- North West
- South East
- South West
- West Midlands South
- Northern Ireland.
- Existing members of the specialty practice group within a professional organization were contacted to distribute questionnaires to providers in their regions
- Questionnaires were sent via email with at least three e-mail reminders and telephone or e-mail follow-up as needed
- Additionally, a reminder was published in Dietetics Today professional magazine.
Design?The survey was conducted at a one-time-per-participant assessment but with two components: Part One of the survey was completed by the manager; Part Two was completed by the dietitian providing direct services, when applicable.
Statistical Analysis?Statistical Analysis for the Social Sciences (SPSS version 11.0; Chicago, IL, USA)
- Chi square
- Analysis of variance
- Multiple regression.
Timing of MeasurementsOne-time questionnaire.
- Level of service (number of dietitian hours dedicated to celiac patients per month)
- Level of responsibility (grade or training level of dietitian providing services to celiac patients)
- Number of times patients were seen (new diagnosis, three-month, six-month, annual).
- Age of patients (adult, child)
- Setting for care provision
- Presence of multi-disciplinary team
- Membership in a professional organization or practice group
- Presence of policy for care management
- Participation in Coeliac UK.
- Initial N: 328 questionnaires sent
- Attrition (final N): 123 (38%) questionnaires returned
- Age: Not applicable
- Ethnicity: Not applicable
- Other relevant demographics: Response rate ranged greatly (5% in South West to 71% in Northern Ireland and 75% in West Midlands)
- Location: 14 regions of the United Kingdom.
- There was positive significant correlation (R=0.54, P<0.001) between number of full-time equivalent dietitians working in a department and the number of hours allocated to provision of service for celiac patients, independent of population size
- Having a specialist dietitian in gastroenterology was significantly associated with more hours per 100,000 in population being allocated to celiac patients (P=0.002)
- A total of 12 departments had specific funding for celiac patients and the number of hours available was double that in others without specific funding (P=0.012)
- A total of 21 departments where a dietitian was part of a multi-disciplinary team allocated 4.1 hours per 100,000 in population, compared to 2.6 hours in the other 61 departments (P=0.012)
- Departments with a multi-disciplinary team (P=0.001) or a designated celiac dietitian (P=0.002) were more likely to have involvement with the Gastroenterology Interest Group and ongoing training
- The number of hours devoted to celiac patients per 100,000 in population in nine departments that attended British Dietetic Association (BDA) training was more than the number of hours in the 70 departments that did not attend BDA training (P<0.001).
- 13% of departments allocated no specific time to celiac patients
- 67 departments had a staff member designated for treatment of celiac patients; 50 of these departments were a Senior II grade or higher. Most patients were seen in outpatient clinics (87.9%) or as inpatients (72.7%). Less than 10% were seen in specialist celiac clinics, however more time was allocated in this setting.
- A total of 37 (30%) departments reported that the dietitian worked as part of a multi-disciplinary team in treatment of celiac patients
- A total of 73 (59%) departments reported having a policy for the management of celiac disease. Of these, 62 (85%) used the British Society of Gastroenterology (BSG) guidelines.
- Newly diagnosed patient were seen in under two weeks, by 43% of departments and two to four weeks in 41%. Follow-up timing varied greatly without significant trends to report.
- Based on the current, yet probably under-diagnosed, prevalence of celiac disease in the United Kingdom and the minimal provision of one half hour per celiac patient per year, there would be a minimum requirement of eight hours of dietetic services provided per month per 100,000 in population. This is almost three times the average current level of services provided as reported in this survey.
- The current level of dietetic services provided is well below what is needed to allow dietitians to give celiac patients across the United Kingdom basic dietetic support as recommended by the British Society of Gastroenterology.

- The response rates to the survey process were low and recognized by the authors
- Possible bias due to questionnaires provided through specialty group of professional organization, no blinding and sponsorship of Coeliac UK organization.
