Comparison of knowledge and awareness between consultant physicians and resident doctors about non-alcoholic fatty liver disease

AIM OF THE STUDY: Non-alcoholic fatty liver disease (NAFLD) is a multisystem disease and is commonly associated with diabetes mellitus, dyslipidaemia, hypertension and obesity. These illnesses are usually treated by physicians, and hence they need to stay updated on NAFLD. The aim of the study was to assess and compare the knowledge and awareness about NAFLD among consultant physicians and resident doctors. MATERIAL AND METHODS: A questionnaire concerning epidemiology, risk factors, complications, diagnostic methods, management options, progression and screening of NAFLD was given to the consultant physicians and resident doctors and their responses were sought. The comparison of responses was carried out between residents and consultants using Pearson’s χ(2) test. RESULTS: A total of 240 doctors participated in the study with 60 resident doctors and 180 consultant physicians. 45% of the total participants did not consider NAFLD as a major health hazard. Consultants had better knowledge than residents about the prevalence of NAFLD, and the risks due to various factors. Also they had better knowledge about non-invasive diagnostic modalities. Resident doctors advocated use of antioxidants more than consultants. There was no statistically significant difference of perception between residents and physicians about association of NAFLD with diabetes and obesity, diet advice, dietary modification and exercise, usage of medications, avoidance of hepatotoxic drugs and alcohol. CONCLUSIONS: This study revealed that physicians participating in our survey appreciate the prevalence of NAFLD but are unaware of the seriousness and the optimal management. This has implications for targeting ‘at-risk’ populations and appropriate referral of patients to gastroenterology/hepatology clinics.
