Accidental needlestick injury rate among healthcare workers in Hawassa is extremely high. Epidemiological findings proved the infectious potential of this injury contaminated with a Human Immunodeficiency Virus (HIV)-infected patient's blood.
This study aimed at estimating the risk of HIV transmission from patients to healthcare workers in Hawassa City, Ethiopia.
A probabilistic risk model was employed. Scenario-based assumptions were made for the values of parameters following a review of published reports between 2007 and 2010.
HIV prevalence, needlestick injury rate, exposure rate, sero-conversion rate, risk of HIV transmission and cumulative risk of HIV transmission.
Generally, healthcare workers in Hawassa are considered to be at a relatively low (0.0035%) occupational risk of contracting HIV - less than 4 in 100,000 of healthcare workers in the town (1 in 28,751 workers a year). The 30 years' maximum cumulative risk estimate is approximately five healthcare workers per 1000 workers in the study area. Still, this small number should be considered a serious matter requiring post-exposure prophylaxis following exposure to unsafe medical practice leading to HIV infection.
在 Hawassa，医护人员发生意外针刺伤的比率极高。流行病学研究结果表明，这种由 HIV 感染患者血液污染的针刺伤具有感染性。
本研究旨在评估在埃塞俄比亚 Hawassa 市，患者将 HIV 传染给医护人员的风险。
采用概率风险模型。根据 2007 年至 2010 年期间发表的报告，对参数值进行基于情景的假设。
HIV 流行率、针刺伤发生率、暴露率、血清转化率、HIV 传播风险和 HIV 传播累积风险。
总体而言，Hawassa 的医护人员被认为职业感染 HIV 的风险相对较低（0.0035%）-每 100000 名医护人员中不到 4 人（每年每 28751 名医护人员中有 1 人）。30 年的最大累积风险估计约为每 1000 名医护人员中有 5 名医护人员。尽管如此，这一少数人数仍应被视为一个严重的问题，需要在发生不安全的医疗操作导致 HIV 感染后进行暴露后预防。
