More countries are using verbal autopsy as a part of routine mortality surveillance. The length of time required to complete a verbal autopsy interview is a key logistical consideration for planning large-scale surveillance.
We use the PHMRC shortened questionnaire to conduct verbal autopsy interviews at three sites and collect data on the length of time required to complete the interview. This instrument uses a novel checklist of keywords to capture relevant information from the open response. The open response section is timed separately from the section consisting of closed questions.
We found the median time to complete the entire interview was approximately 25 minutes and did not vary substantially by age-specific module. The median time for the open response section was approximately 4 minutes and 60% of interviewees mentioned at least one keyword within the open response section.
The length of time required to complete the interview was short enough for large-scale routine use. The open-response section did not add a substantial amount of time and provided useful information which can be used to increase the accuracy of the predictions of the cause of death. The novel checklist approach further reduces the burden of transcribing and translating a large amount of free text. This makes the PHMRC instrument ideal for national mortality surveillance.
越来越多的国家将口头尸检作为常规死亡率监测的一部分。完成一次口头尸检访谈所需的时间长度是规划大规模监测时的一个关键后勤考量因素。
我们使用PHMRC简化问卷在三个地点进行口头尸检访谈，并收集完成访谈所需时间的数据。该工具使用一份新颖的关键词清单从开放式回答中获取相关信息。开放式回答部分与封闭式问题部分分开计时。
我们发现完成整个访谈的中位时间约为25分钟，并且按年龄特定模块划分差异不大。开放式回答部分的中位时间约为4分钟，60%的受访者在开放式回答部分提到了至少一个关键词。
完成访谈所需的时间长度足够短，适合大规模常规使用。开放式回答部分并未增加大量时间，且提供了可用于提高死因预测准确性的有用信息。新颖的清单方法进一步减轻了转录和翻译大量自由文本的负担。这使得PHMRC工具成为国家死亡率监测的理想选择。
