Cross-sectional survey on occupational needle stick injuries amongst prehospital emergency medical service personnel in Johannesburg.

Abstract

IntroductionPrehospital personnel are exposed to challenging situations that place them at increased risk of sustaining a needle stick injury (NSI). Blood borne infections such as HIV and Hepatitis B or C may be transmitted from a NSI. Sub-Saharan Africa has the largest number of people living with HIV globally. There is no data pertaining to NSI among Emergency Medical Service (EMS) personnel in South Africa. This study aimed to investigate the cumulative incidence, knowledge, attitudes and practices pertaining to NSIs amongst a select group of prehospital personnel in Johannesburg.MethodsThis was a prospective, questionnaire based, cross-sectional survey of personnel employed at three EMS service providers in Johannesburg.ResultsOf the 240 subjects that participated in the study, there was a total of 93 NSIs amongst 63 (26.3%) subjects. Of these, 41 (65.1%) had sustained one previous NSI, 16 (25.4%) had two NSIs, 5 (7.9%) had three NSIs and one (1.6%) had five NSIs. Almost two-thirds (n = 60; 64.5%) of NSIs were sustained during intravenous line insertion. Most of the study subjects were male (n = 145, 60.4%), between the age of 25–29 years (n = 67, 27.9%), had a BLS qualification as the highest level of training (n = 89, 37.1%), had >10 years of EMS experience (n = 69; 28.8%) and were up to date with their Hepatitis B vaccination at the time of the study. HIV post exposure prophylaxis (PEP) was initiated in 82 (88.2%) out of the 93 NSI incidents. However, the recommended 28-day course of therapy was only completed in 68 (82.9%) out of the 82 cases where PEP was initiated.ConclusionPrehospital personnel are at risk of sustaining a NSI. There is a need to promote awareness with regards to the risks, preventive measures, awareness of PEP protocols and the timely initiation and completion of HIV PEP amongst EMS personnel in Johannesburg.
