尽管低收入和中低收入国家迫切需要及时的死亡率数据，但手机调查很少包括有关最近死亡人数的问题。这样的问题可能a)太敏感，b)询问时间太长和/或c)产生不可靠的数据。我们评估了在马拉维使用移动电话调查收集死亡率数据的可行性。我们在随机抽样的手机用户中进行了一项非自卑试验。参与者被分配到一次关于他们最近的经济活动或最近家人去世的访谈。在被问到与死亡相关的问题的那组人中，一半的受访者完成了一份简短的问卷，重点是计算最近死亡率所需的信息，而另一半人完成了一份扩展的问卷，其中也包括有关症状和医疗保健的问题。试验的主要结果是合作率，即完成采访的次数除以受邀参加的移动用户人数。次要结果包括自我报告的负面情绪和声明的意图，参加未来的采访。我们拨打了7000多个唯一号码，移动用户达到3054人。总共有1,683名移动用户被邀请参加。被要求完成死亡相关访谈的人与被要求回答有关经济活动的问题的人之间的合作率差异为0.9个百分点(95%CI=-2.3，4.1)，满足非自卑标准。死亡率调查问卷在所有次级结果方面都不逊于经济调查问卷。根据是否包括有关症状和医疗保健的问题，每次报告的死亡人数需要额外收集2到4分钟的死亡率数据。最近在手机访谈中发现的死亡案例中，有一半以上没有在国家登记局登记。将与死亡相关的问题纳入手机调查是可行的。这可能有助于加强对民事登记系统不完善国家的死亡率监测。登记：AEA RCT登记处，0008065号(2021年9月14日)。
Despite the urgent need for timely mortality data in low-income and lower-middle-income countries, mobile phone surveys rarely include questions about recent deaths. Such questions might a) be too sensitive, b) take too long to ask and/or c) generate unreliable data. We assessed the feasibility of mortality data collection using mobile phone surveys in Malawi. We conducted a non-inferiority trial among a random sample of mobile phone users. Participants were allocated to an interview about their recent economic activity or recent deaths in their family. In the group that was asked mortality-related questions, half of the respondents completed an abridged questionnaire, focused on information necessary to calculate recent mortality rates, whereas the other half completed an extended questionnaire that also included questions about symptoms and healthcare. The primary trial outcome was the cooperation rate, i.e., the number of completed interviews divided by the number of mobile subscribers invited to participate. Secondary outcomes included self-reports of negative feelings and stated intentions to participate in future interviews. We called more than 7,000 unique numbers and reached 3,054 mobile subscribers. In total, 1,683 mobile users were invited to participate. The difference in cooperation rates between those asked to complete a mortality-related interview and those asked to answer questions about economic activity was 0.9 percentage points (95% CI = -2.3, 4.1), which satisfied the non-inferiority criterion. The mortality questionnaire was non-inferior to the economic questionnaire on all secondary outcomes. Collecting mortality data required 2 to 4 additional minutes per reported death, depending on the inclusion of questions about symptoms and healthcare. More than half of recent deaths elicited during mobile phone interviews had not been registered with the National Registration Bureau. Including mortality-related questions in mobile phone surveys is feasible. It might help strengthen the surveillance of mortality in countries with deficient civil registration systems.
