Mobile technologies are emerging as tools to enhance health service delivery systems and empower clients to improve maternal, newborn, and child health. Limited evidence exists on the value for money of mobile health (mHealth) programs in low- and middle-income countries.
This study aims to forecast the incremental cost-effectiveness of the Mobile Technology for Community Health (MOTECH) initiative at scale across 170 districts in Ghana.
MOTECH's "Client Data Application" allows frontline health workers to digitize service delivery information and track the care of patients. MOTECH's other main component, the "Mobile Midwife," sends automated educational voice messages to mobile phones of pregnant and postpartum women. We measured program costs and consequences of scaling up MOTECH over a 10-year analytic time horizon. Economic costs were estimated from informant interviews and financial records. Health effects were modeled using the Lives Saved Tool with data from an independent evaluation of changes in key services coverage observed in Gomoa West District. Incremental cost-effectiveness ratios were presented overall and for each year of implementation. Uncertainty analyses assessed the robustness of results to changes in key parameters.
MOTECH was scaled in clusters over a 3-year period to reach 78.7% (170/216) of Ghana's districts. Sustaining the program would cost US $17,618 on average annually per district. Over 10 years, MOTECH could potentially save an estimated 59,906 lives at a total cost of US $32 million. The incremental cost per disability-adjusted life year averted ranged from US $174 in the first year to US $6.54 in the tenth year of implementation and US $20.94 (95% CI US $20.34-$21.55) over 10 years. Uncertainty analyses suggested that the incremental cost-effectiveness ratio was most sensitive to changes in health effects, followed by personnel time. Probabilistic sensitivity analyses suggested that MOTECH had a 100% probability of being cost-effective above a willingness-to-pay threshold of US $50.
This is the first study to estimate the value for money of the supply- and demand-side of an mHealth initiative. The adoption of MOTECH to improve MNCH service delivery and uptake represents good value for money in Ghana and should be considered for expansion. Integration with other mHealth solutions, including e-Tracker, may provide opportunities to continue or combine beneficial components of MOTECH to achieve a greater impact on health.
移动技术正逐渐成为增强卫生服务提供系统以及使客户有能力改善孕产妇、新生儿和儿童健康状况的工具。关于低收入和中等收入国家移动健康(mHealth)项目性价比的证据有限。
本研究旨在预测“社区健康移动技术”(MOTECH)倡议在加纳170个地区全面推广后的增量成本效益。
MOTECH的“客户数据应用程序”使一线卫生工作者能够将服务提供信息数字化并跟踪患者护理情况。MOTECH的另一个主要组成部分“移动助产士”会向孕妇和产后妇女的手机发送自动教育语音信息。我们在10年的分析期内衡量了扩大MOTECH规模的项目成本和结果。经济成本通过与知情者访谈和财务记录进行估算。使用“挽救生命工具”,根据在戈莫阿西区观察到的关键服务覆盖范围变化的独立评估数据对健康影响进行建模。呈现了总体以及每年实施的增量成本效益比。不确定性分析评估了结果对关键参数变化的稳健性。
MOTECH在3年时间内分批次进行推广,覆盖了加纳78.7%(170/216)的地区。维持该项目平均每个地区每年将花费17,618美元。在10年期间,MOTECH可能总共挽救约59,906条生命,总成本为3200万美元。避免每一个伤残调整生命年的增量成本从第一年的174美元到实施第十年的6.54美元,10年期间为20.94美元(95%置信区间为20.34 - 21.55美元)。不确定性分析表明,增量成本效益比最敏感于健康影响的变化,其次是人员时间。概率敏感性分析表明,MOTECH在支付意愿阈值为50美元以上时具有100%的成本效益概率。
这是第一项估计mHealth倡议供需双方性价比的研究。在加纳采用MOTECH来改善孕产妇、新生儿和儿童健康服务的提供和接受情况具有良好的性价比,应考虑扩大推广。与其他mHealth解决方案(包括电子追踪器)整合,可能提供继续或结合MOTECH有益部分以对健康产生更大影响的机会。
