Awareness of chronic liver diseases, a comparison between diabetologists and general practitioners

Backgrounds and aims: Because of the high prevalence of chronic liver disease (CLD), it is crucial that general practitioners (GPs, in contact with the general population) and diabetologists (in contact with the most at-risk non-alcoholic fatty liver disease population) identify patients with advanced CLD requiring specialized management. The aim of this study was to evaluate CLD and CLD management awareness among diabetologists and GPs.

Material and methods: A questionnaire was sent to diabetologists within the Francophone Diabetes Society and to GPs in southern and western France. The questionnaire sounded participant characteristics and knowledge of CLD and its management.

Results: 678 questionnaires were completed by 500 GPs and 178 diabetologists. CLD prevalence was underestimated by 90% of GPs and 59% of diabetologists (p<0.001). For biological CLD follow-up, liver injury explorations (transaminases) were systematically included whereas severity explorations (prothrombin time, bilirubin) were prescribed for less than 50% of blood samples; GPs were more likely to prescribe severity explorations than diabetologists were (p<0.001). 74% of GPs and 97% of diabetologists (p<0.001) were familiar with non-invasive tests, Fibroscan and Fibrotest being the two most-frequently mentioned of them. In contrast, the simple blood test Fibrosis-4 was cited by less than 15% of GPs and 30% of diabetologists (p<0.001).

Conclusion: GPs and diabetologists have limited knowledge of CLD, despite its high prevalence. Continuing medical education among GPs and diabetologists is therefore necessary to enable the discovery of patients with advanced fibrosis and early management for them so as to avoid liver-related complications.
