Survey on knowledge of non-alcoholic fatty liver disease (NAFLD) among doctors in Sri Lanka: A multicenter study

Abstract

Objectives: There has been a global increase in the incidence and prevalence of NAFLD. We assessed the knowledge and awareness of NAFLD among gastroenterology doctors in three state sector hospitals. Results: 80 medical officers and 58 post-graduate trainee doctors/consultants responded. 110 (79.7%) considered NAFLD a major health problem whilst 97 (70.3%) thought the prevalence of NAFLD was 10-40%. 52.9% saw 12-24 patients with NAFLD/year. A vast majority knew the risk factors for NAFLD: 127 (92.7%) diabetes mellitus, 135 (97.8%) Obesity, 132 (95.7%) Dyslipidemia and 87 (63%) PCOS. The methods for diagnosis were recognized by: USS 132 (95.7%), MRI 34 (24.6%), transient elastography 23 (16.7%) and liver biopsy 88 (63.8%) while, 53 (38.4%) recognized the non-invasive methods available for diagnosis. The trends in referral were lower than expected: 85 (61.6%) refer to a Gastroenterologist/Physician, 53 (38.4%) to a Gym, 67 (48.6%) to a weight loss clinic and 45 (32.6%) to a dietician. Significantly more postgraduate trainee doctors: recognized the availability of non-invasive investigations for NAFLD (P = 0.01) and read guidelines on NAFLD (P = 0.02) compared to non-trainee doctors. As a whole, a majority (57.2%) had not attended a lecture or read a guideline on NAFLD. The barriers for management included: lack of confidence 70 (50.7%) and time constraints 58 (42%).
