Individuals living with HIV face challenging employment decisions that have personal, financial, and health impacts. The decision to stay or to leave the work force is much more complicated for an individual with HIV because the financial choices related to potential health benefits are not clearly understood. To assist in the decision-making process for an individual with HIV, we propose to develop a decision model that compares the potential costs and benefits of staying in or leaving the work force.
A hypothetical cohort of HIV-infected individuals was simulated in our decision model. Characteristics of these individuals over a one-year period were extracted from the medical literature and publicly available national surveys. Men and women between the ages of 18 and 59 were included in our simulated cohort.
A decision tree model was created to estimate the financial impact of an individual's decision on employment. The outcomes were presented as the cost-savings associated with the following employment statuses over a one-year period: 1) staying full-time, 2) switching from full-to part-time, 3) transitioning from full-time to unemployment, and 4) staying unemployed. CD4 T cell counts and employment statuses were stratified by earned income. Employment probabilities were calculated from national databases on employment trends in the United States. Sensitivity analyses were conducted to test the robustness of the effects of the variables on the outcomes.
Overall, the decision outcome that resulted in the least financial loss for individuals with HIV was to remain at work. For an individual with CD4 T cell count > 350, the cost difference between staying employed full-time and switching from full-time to part-time status was a maximum of $2,970. For an individual with a CD4 T cell count between 200 and 350, the cost difference was as low as $126 and as great as $2,492. For an individual with a CD4 T cell count < 200, the minimum cost difference was $375 and the maximum cost difference was $2,253.
Based on our simulated model, we recommend an individual with CD4 T cell count > 350 to stay employed full-time because it resulted in the least financial loss. On the other hand, for an individual with a CD4 T cell < 350, the financial cost loss was much more variable. Our model provides an objective decision-making guide for individuals with HIV to weigh the costs and benefits of employment decisions.
感染艾滋病毒的个体面临具有个人、经济和健康影响的具有挑战性的就业决策。对于感染艾滋病毒的个体而言,决定继续留在劳动力队伍还是离开要复杂得多,因为与潜在健康益处相关的财务选择并未得到清晰理解。为协助感染艾滋病毒的个体进行决策,我们提议开发一种决策模型,该模型比较继续留在劳动力队伍或离开的潜在成本和收益。
在我们的决策模型中模拟了一组假设的艾滋病毒感染个体。这些个体在一年期间的特征是从医学文献和公开可得的全国性调查中提取的。年龄在18至59岁之间的男性和女性被纳入我们模拟的队列。
创建了一个决策树模型来估计个体就业决策的财务影响。结果以与以下一年期间就业状况相关的成本节省来呈现:1)全职工作,2)从全职转为兼职,3)从全职转为失业,4)保持失业。CD4 T细胞计数和就业状况按收入分层。就业概率是根据美国就业趋势的国家数据库计算得出的。进行了敏感性分析以测试变量对结果影响的稳健性。
总体而言,对感染艾滋病毒的个体来说导致财务损失最小的决策结果是继续工作。对于CD4 T细胞计数>350的个体,全职工作和从全职转为兼职状态之间的成本差异最大为2970美元。对于CD4 T细胞计数在200至350之间的个体,成本差异低至126美元,高至2492美元。对于CD4 T细胞计数<200的个体,最小成本差异为375美元,最大成本差异为2253美元。
基于我们的模拟模型,我们建议CD4 T细胞计数>350的个体全职工作,因为这导致的财务损失最小。另一方面,对于CD4 T细胞<350的个体,财务成本损失变化更大。我们的模型为感染艾滋病毒的个体权衡就业决策的成本和收益提供了一个客观的决策指南。
