Without large increases in the number of health workers to treat HIV/AIDS (HAHW) many countries in sub-Saharan Africa will be unable to achieve universal coverage with antiretroviral treatment (ART), leading to large numbers of avoidable deaths among people living with HIV/AIDS. We conduct a cost-benefit analysis of a health care education scholarship that is conditional on the recipient committing to work for several years after graduation delivering ART in sub-Saharan Africa. Such a scholarship could address two of the main reasons for the low numbers of health workers in sub-Saharan Africa: low education rates and high emigration rates. We use Markov Monte Carlo microsimulation to estimate the expected net present value (eNPV) of "conditional scholarships" in sub-Saharan Africa. The scholarships are highly eNPV-positive under a wide range of assumptions. Conditional scholarships for a HAHW team sufficient to provide ART for 500 patients have an eNPV of 1.24 million year-2000 US dollars, assuming that the scholarship recipients are in addition to the health workers who would have been educated without scholarships and that the scholarships reduce annual HAHW emigration probabilities from 15% to 5% for five years. The eNPV of the education effect of the scholarships is larger than eNPV of the migration effect. Policy makers should consider implementing "conditional scholarships" for HAHW, especially in countries where health worker education capacity is currently underutilized or can be rapidly expanded.
如果没有大幅增加治疗艾滋病毒/艾滋病的卫生工作者数量,撒哈拉以南非洲的许多国家将无法实现抗逆转录病毒治疗的普及,从而导致大量艾滋病毒/艾滋病感染者死亡,而这些死亡是可以避免的。我们对一项医疗保健教育奖学金进行了成本效益分析,该奖学金的条件是获得者承诺毕业后在撒哈拉以南非洲从事数年的抗逆转录病毒治疗工作。这样的奖学金可以解决撒哈拉以南非洲卫生工作者数量少的两个主要原因:低教育率和高移民率。我们使用马尔可夫蒙特卡罗微观模拟来估计撒哈拉以南非洲“有条件奖学金”的预期净现值(eNPV)。在广泛的假设下,这些奖学金的eNPV为高度正值。假设奖学金获得者是在没有奖学金的情况下本来也会接受教育的卫生工作者之外的人员,并且奖学金在五年内将卫生工作者的年度移民概率从15%降低到5%,那么为一个足以向500名患者提供抗逆转录病毒治疗的艾滋病毒/艾滋病卫生工作者团队提供的有条件奖学金的eNPV为124万美元(按2000年美元计算)。奖学金教育效果的eNPV大于移民效果的eNPV。政策制定者应考虑为艾滋病毒/艾滋病卫生工作者实施“有条件奖学金”,特别是在目前卫生工作者教育能力未得到充分利用或可以迅速扩大的国家。
