Knowledge, attitudes and practice of Iranian medical specialists regarding hepatitis B and C.

Background And Aims: Health care workers (HCWs) are at risk of contracting and spreading hepatitis B virus (HBV) and hepatitis C virus (HCV) to others. The aim of this study was to evaluate knowledge, attitudes and behavior of physicians concerning HBV and HCV.

Methods: A 29-item questionnaire (reliability coefficient = 0.7) was distributed at two national/regional congresses and two university hospitals in Iran. Five medical groups (dentists, general practitioners, paraclinicians, surgeons and internists) received 450 questionnaires in 2009, of which 369 questionnaires (82%) were filled out.

Results: Knowledge about routes of transmission of HBV and HCV, prevalence rate and seroconversion rates secondary to a needlestick injury was moderate to low. Concern about being infected with HBV and HCV was 69.4±2.1 and 76.3±2 (out of 100), respectively. Complete HBV vaccination was done on 88.1% of the participants. Sixty percent had checked their hepatitis B surface antibody (anti-HBs), and 83.8% were positive. Only 24% of the surgeons often used double gloves and 28% had reported a needlestick. There was no significant correlation between the different specialties and: concern about HBV and HCV; the underreporting of needlestick injuries; and correct knowledge of post-needlestick HBV infection.

Conclusions: Although our participants were afraid of acquiring HBV and HCV, knowledge about routes of transmission, prevalence, protection and post-exposure seroconversion rates was unsatisfactory. By making physicians aware of possible post-exposure prophylaxis, the underreporting of needlestick injuries could be eliminated. Continuous training about HBV and HCV transmission routes, seroconversion rates, protection, as well as hepatitis B vaccination and checking the anti-HBs level, is a matter of necessity.
