ABSTRACT
Hepatitis B virus [HBV] infection is a recognized occupational risk for health care workers [HCWs]. This study aimed to assess the knowledge and beliefs of HCWs regarding HBV transmission and needle stick injuries [NSIs]. A cross-sectional questionnaire based KAP study was conducted at Civil Hospital, Karachi, during the period of January to September 2006. HCWs were inquired about possible modes of HBV transimission and association with NSIs. Data were entered using Epilnfo 6.04d software. Statistical analysis was performed using SPSS 12.5 software. A total of 343 HCWs participated, and those answered at least 5 correct modes of HBV transmission were considered knowledgeable. Knowledgeable group was more likely to report NSIs [p<0.006], more vaccinated [p<0.001] and were also more likely to attend awareness session [p< 0.009]. Overall knowledge were inadequate and behaviour and attitude towards clinical practices were found compromised. To reduce the occupational risk, effort should be focused to establish effective infection control program and training of staff
