Abstract:
Objective To investigate the knowledge awareness of medical staff in department of Obstetrics and Gynecology,on prevention of mother-to-child transmission of hepatitis B virus(HBV).Methods Medicatl staff,who attended national or local medical conferences of Obstetrics and Gynecology from July 29th to October 25th in 2011,were invited to complete a questionnaire containing questions on clinical implications of HBV serologic markers,relevant prevention measures and including intervention measures for both pregnant women and infants.Data were collected and analyzed by Chi-square test or Fisher's exact test.Results A total of 559 answers were analyzed.Of the 559 staff,85.0％(n=475) were doctors and 15.0％(n=84) were nurses.The percentages ofstaff from primary,secondary and tertiary hospitals were 13.2％(n=74),36.9％(n=206) and 49.9％ (n=279).Overall,90.0％ (503/559) participants agreed that positive hepatitis B surface antigen (HBsAg) was contagious,but 27.5％ (154/559) mistook that the presence of antibody against hepatitis B e antigen (anti-HBc) and/or antibody against hepatitis B core antigens (anti-HBc) with negative HBsAg was contagious.Totally,96.3％ (519/539) respondents knew that pregnant women should be screened for HBV infection,and those from secondary hospitals had more consciousness of HBV screening for pregnant women than those from tertiary hospitals [99.0％ (201/203) vs94.7％(250/264),x2=6.466,P=0.011].Although,95.3％ (511/536) realized that infants of mothers with positive HBsAg should receive hepatitis B immunoglobulin (HBIG) and vaccination,but 61.6％ (330/536) and 80.4％ (427/531) of the enrolled medical staff knew the exact regimen.With the available immunoprophylaxis,13.8％ (74/536) participants mistakenly believed that cesarean section may prevent HBV mother-to-child transmission,and only 13.0％ (69/532) correctly answered that neonates of women with positive HBsAg can be breast-fed.Additionally,54.4％ (290/533) participants mistakenly believed that HBsAg positive pregnant women needed HBIG injection during pregnancy to reduce HBV mother to-child transmission.Conclusions Medical staff in obstetric and gynecological department has essentially mastered the strategies of prevention of mother-to-child transmission of HBV,but much more details should be stressed.
