Carbohydrate counting in type 1 diabetes mellitus: dietitians’ perceptions, training and barriers to use

Objectives A study was undertaken to determine the perceptions, training and barriers regarding the use of carbohydrate counting in the dietary management of type 1 diabetes mellitus (T1DM) among dietitians in KwaZulu-Natal (KZN). Design A cross-sectional, descriptive study was conducted. Setting Dietitians who were registered with the Health Professions Council of South Africa (HPCSA), and working in the province of KZN at the time of the study, were invited to participate. Methods Data were collected using a self-administered electronic questionnaire distributed through SurveyMonkey, an Internet-based survey programme. Results Dietitians agreed that carbohydrate counting was a useful dietary management approach for diabetes (p < 0.05) and that it was essential to manage T1DM (p < 0.05). However, they felt it was a difficult concept for patients with T1DM to understand (p = 0.001) and teaching it to patients was time consuming (p < 0.05). Although dietitians believed that there was a strong evidence base for teaching carbohydrate counting to patients with T1DM (p < 0.05), they indicated a need for further training or education in it (p < 0.05). Barriers to using carbohydrate counting included a lack of training, confidence and experience, financial resources, time, blood glucose records and poor patient motivation and patient illiteracy (p < 0.05). Conclusions Overall, dietitians who participated in the study had a positive perception towards the use of carbohydrate counting in the management of T1DM. However, further training needs to be addressed for carbohydrate counting to be used with confidence by dietitians in KZN to optimize their management of T1DM.
