[National study of screening practices for hepatitis C among hemodialysis patients. Hepatitis Group]

Abstract

French and American consensus conferences on hepatitis C confirmed the burden of that disease, especially in high risk populations. In France, the seroprevalence of HCV is about 20% among haemodialysed patients. This study aimed at describing the French screening practices in haemodialysed patients. In 1995, 1213 self-administered questionnaires were sent to nephrologists working in 715 dialysis units. The response rate was 48% (585/1213) and 485 questionnaires were analysed. In 98% of questionnaires nephrologists answered that they prescribed screening test. Routine screening with alanine amino-transferase (ALT) was reported in 98% of questionnaires, usually once a month (57%) or four times a year (23%). Routine anti-HCV serology was reported by 96%, usually once (28%) or twice (46%) a year. The two main annual strategies combining ALT and anti-HCV serology were 12 ALT and 2 serologies (21%), or 12 ALT and 1 serology (14%) per year. HCV RNA detection was reported mainly in the case of positive anti-HCV serology (70%). The study suggested heterogeneity in screening practices and revealed the need to determine the cost-effectiveness ratios of the various strategies.
