For most low– and middle–income countries (LMICs), distribution of child causes of death is usually derived from community–based verbal autopsy (VA) studies applying systematic modeling [<xref rid="R4" ref-type="bibr">4</xref>–<xref rid="R6" ref-type="bibr">6</xref>]. In the meantime, an increasing number of national VA studies have been conducted and more are becoming available [<xref rid="R6" ref-type="bibr">6</xref>–<xref rid="R15" ref-type="bibr">15</xref>]. While empirical data mounts to fill the large information gap of causes of child mortality across LMIC [<xref rid="R4" ref-type="bibr">4</xref>,<xref rid="R6" ref-type="bibr">6</xref>,<xref rid="R16" ref-type="bibr">16</xref>], how to improve consistency and comparability of national VA results should be considered for the purpose of global comparison.</p><p>VA studies by design should be consistent and comparable when used to generate population level cause–of–death estimates [<xref rid="R17" ref-type="bibr">17</xref>]. In practice, the data collection procedures have been relatively standardized in the national VA studies conducted in the past two decades [<xref rid="R7" ref-type="bibr">7</xref>,<xref rid="R9" ref-type="bibr">9</xref>–<xref rid="R15" ref-type="bibr">15</xref>]. However, when applying national VA data to derive cause–of–death estimates, at least two different methodologies have been applied, including physician review, computer algorithm and probabilistic approaches [<xref rid="R17" ref-type="bibr">17</xref>]. The methodological differences in these ascertaining approaches impede direct comparison across estimates.</p><p>Compared to computer algorithm, physician review has the apparent disadvantage of involving a large team of physicians. This may intervene with the routine function of the health care systems in many LMICs. In addition, physician review derived cause–of–death estimates may have limited internal consistency due to concerns over repeatability of the approach [<xref rid="R7" ref-type="bibr">7</xref>,<xref rid="R14" ref-type="bibr">14</xref>,<xref rid="R15" ref-type="bibr">15</xref>,<xref rid="R17" ref-type="bibr">17</xref>]. Physicians may also interpret VA with subjectivity and judgment [<xref rid="R17" ref-type="bibr">17</xref>]. Relying extensively on the open narrative of the circumstances surrounding the death event, physicians can use specific diagnostic techniques differing considerably between individuals and settings. Biased by their prior knowledge of local epidemiology, physicians are also found to be reluctant to assign unexpected causes of death, while favoring some highly specific diagnosis without adequate evidence. Even though two physicians can have high level of agreement, the agreement may simply reflect their similar medical experiences, but does not ensure the results are comparable with those generated in a different time or place [<xref rid="R17" ref-type="bibr">17</xref>].

Specifically, the primary caregiver of the deceased child was interviewed about symptoms, signs, and health care received before death with instruments adopted from the standardized WHO VA questionnaires for neonatal and child deaths [<xref rid="R24" ref-type="bibr">24</xref>]. Causes of deaths were originally ascertained by two trained physicians independently reviewing both the structured and open–ended narrative sections of the completed VA questionnaires, and coded according to the International Classification of Diseases, 10<sup>th</sup> revision (ICD–10). If discordant ICD–10 codes were assigned by the two coding physicians, a single cause of death was agreed upon after deliberation.</p><p>We did not have access to the open–ended narrative data and focused the current analyses on the structured section of the VA questionnaires. We applied the following criteria to only include children who: 1) were identified as live births; 2) died between ages 0 and 59 months; 3) had complete VA interviews; 4) had sufficient information on age at death; and 5) were administered age–appropriate questionnaire.</p></sec><sec><title>Standardized computer algorithm</title><p>We adapted a previously developed standardized computer algorithm to assign causes of death [<xref rid="R8" ref-type="bibr">8</xref>]. The algorithm was consisted of case definitions and a hierarchical process. The case definitions were combinations of cause–specific signs and symptoms (see <bold>Online Supplementary Document<xref ref-type="supplementary-material" rid="S1">(Online Supplementary Document)</xref></bold>). Generally, the algorithm only allowed one cause for each death. But deaths due to measles, diarrhea and acute respiratory infection (ARI) can be assigned simultaneously, and then re–distributed into the respective single cause according to their cause–specific mortality fractions (CSMFs) assigned before the re–distribution. Causes were assigned through a hierarchical process in which diagnoses with more specific symptoms were made before those with less specific ones, and cases without any diagnosis at the end were classified as unspecified conditions (<xref ref-type="fig" rid="F1"><bold>Figure 1</bold></xref>). The algorithm contained two parallel hierarchies to assign deaths of children aged 0–27 days and 1–59 months.

We first reviewed several pediatric and adult AIDS case validation studies.

Our final AIDS case definition included any of the following conditions: 1) jaundice; 2) chronic diarrhea lasted for more than 1 month; 3) chronic fever lasted for more than 1 month; 4) wasting, defined as having at least 1 of the following symptoms – paleness, hair color change, edema legs, dry scaly skin; and 5) cough or trouble breathing lasting 3 to 27 days with fever but without a recent diagnosis of tuberculosis. We chose not to assign AIDS among neonates considering the likely low specificity of our preliminary case definition and the low incidence (only approximately 1.6% of all under–five AIDS deaths occur in the first 28 days (personal communication with Neff Walker). Among children aged 1–59 months, AIDS was placed after malaria in the hierarchy.</p><p>We also added meningitis/encephalitis and neonatal sepsis in the algorithm. We adopted case definitions of the two conditions from WHO [<xref rid="R25" ref-type="bibr">25</xref>], and placed meningitis and neonatal sepsis after ARI and possible diarrhea/ARI, respectively.

distributions by applying an adapted standardized computer algorithm to re–analyze national VA data collected in Uganda, Rwanda and Ghana in 2007–2008. Overall, the distribution of child mortality is by and large similar across the three countries based on our results, with malaria and pneumonia being the leading causes of under–five deaths and intrapartum–related complications and preterm birth complications being the major neonatal causes.</p><p>However, the distribution in Ghana appeared to be different from that in the other two countries in that the diarrhea–specific mortality fraction was much smaller, the AIDS–specific mortality fraction was larger, and more deaths were not assigned. We speculated that the differences between Ghana and the other two countries may be partially attributable to the measurement and data quality issues in the Ghana VA study. Only 2.5% of under–five deaths were assigned to diarrhea in Ghana, which was implausibly low compared to existing studies [<xref rid="R6" ref-type="bibr">6</xref>,<xref rid="R39" ref-type="bibr">39</xref>]. A closer examination of the Ghana data and our diarrhea case definition revealed that although a large proportion of cases had diarrhea–related symptoms (34% in Ghana, compared to 45% in Uganda and 59% in Rwanda), only a small fraction of these cases had 6 or more stools on days when the symptoms were the most severe (17% in Ghana, compared to 52% in Uganda and 34% in Rwanda). We had no basis to believe that diarrhea symptoms differed between Ghana and the other two countries, and speculated that the discrepancy was partially caused by suboptimal data quality. The suspicion over data quality in Ghana may be further supported by the large AIDS–specific mortality fraction at 8.6%, which was implausibly high given an adult HIV prevalence of 1.8% in 2009 in Ghana [<xref rid="R40" ref-type="bibr">40</xref>]. The fact that a quarter of the under–five deaths were not assigned in Ghana, compared to 17% in Rwanda and 8% in Uganda, also raised the concern over quality of the Ghana VA study. One more explanation of the implausibly high AIDS fraction in Ghana could be the result of not assigning sickle–cell disease as a cause of death.</p><p>The kappa statistics showed substantial to poor agreement between results generated by the two ascertaining methods, suggesting that the individual–level agreement varied greatly by cause. Causes with more distinct signs and symptoms, such as injury, congenital malformation, preterm birth complications, and measles had a higher level of agreement compared to other causes. Malaria also had moderate agreement, which may be associated with its high prevalence. Other infectious causes like pneumonia, diarrhea, sepsis and AIDS all have fair to poor agreement, probably due to their non–specific symptoms and likely comorbidity with other infectious conditions. It is noted that the low specificity associated with infectious causes is not unique to computer algorithm, rather, it is a common issue shared by all methods ascertaining causes of death [<xref rid="R41" ref-type="bibr">41</xref>,<xref rid="R42" ref-type="bibr">42</xref>]. Poor agreement among some causes may also have something to do with the fact that we did not have access to the open narrative section of the VA studies. We could have missed useful information on symptoms and signs prior to death that physicians may have had access to [<xref rid="R41" ref-type="bibr">41</xref>]. However, the accuracy of causes ascertained at the individual–level is less of a concern as the purpose of the standardized computer algorithm is to derive comparable population–level distribution of child mortality.</p><p>The absolute values of CSMFs assigned by the standardized computer algorithm were fairly different from those assigned by physician review among neonates and children aged 1–59 months. However, when ranking of the leading five causes and their specific ranks were compared, many similarities can be drawn between results derived from the two approaches. It suggests that public health policy decisions could be largely similar based on distribution of causes of child mortality derived from both methods [<xref rid="R36" ref-type="bibr">36</xref>].</p><p>The study has several limitations. First, our preliminary child AIDS case definition has not been validated. The fact that the AIDS–specific fraction did not have a linear relationship with the adult HIV prevalence in the three countries could also suggest that our AIDS case definition have unsatisfactory validity. However, more specific signs and symptoms are generally required to improve the validity of the AIDS case definition. Additional efforts are urgently needed to develop and standardize AIDS case definition among children that can be used in national VA studies.</p><p>Second, the standardized computer algorithm assigned 38% of post–neonatal deaths to malaria in Rwanda, which is unlikely to be plausible. CHERG estimated that 3.7% of post–neonatal deaths were attributable to malaria in Rwanda in 2008 [<xref rid="R6" ref-type="bibr">6</xref>]. Another independent exercise by WHO applying a natural history model generated an even smaller fraction [<xref rid="R43" ref-type="bibr">43</xref>]. If the malaria–specific mortality burden was in fact low in Rwanda, the implausibly high malaria fraction assigned by the standardized computer algorithm was likely caused by the high misclassification error associated with low specificity of the malaria case definition and the low cause–specific fraction [<xref rid="R25" ref-type="bibr">25</xref>,<xref rid="R44" ref-type="bibr">44</xref>,<xref rid="R45" ref-type="bibr">45</xref>]. In fact, given the non–specific symptoms and the associated low specificity [<xref rid="R46" ref-type="bibr">46</xref>], concerns have been raised over the suitability of the application of VA to ascertain malaria in low prevalence settings [<xref rid="R26" ref-type="bibr">26</xref>,<xref rid="R47" ref-type="bibr">47</xref>,<xref rid="R48" ref-type="bibr">48</xref>].</p><p>In addition, neither the standardized computer algorithm nor physician review is capable of providing the “true” causes of death. Both approaches could be equally invalid. When the two approaches agree, it does not necessarily mean that there is greater truth to the causes assigned.</p><p>Despite these caveats, it is feasible to re–analyze national VA studies applying a standardized computer algorithm for the purposes of cross–country comparison and global burden of childhood disease estimation. The standardized computer algorithm produced internally consistent and comparable distribution of causes of child mortality in comparison to physician review. It also has the advantage of requiring minimal resources from the health care system. From the public health policy stand point of view, the standardized computer algorithm and physician review also generate similar sets of leading causes of child deaths. The standardized computer algorithm represents a promising way to re–analyze national or sub–national VA studies in place of physician review. It could be further strengthened with improved validity of child AIDS case definitions. The standardized computer algorithm should be of particular importance in sub–Saharan Africa, where human capital and financial shortfalls are the greatest. The application of a standardized computer algorithm on child VA data are one step forward toward the harmonization of cause–of–death reporting and estimation in children younger than five years. Among the CHERG community, discussion is on–going about how to utilize national VA data so that consistent and comparable cause–of–death estimates can be generated across countries and time for the purpose of global burden of childhood disease estimation. We welcome a discussion on this subject among a wider community.</p></sec></body><back><ack><title>Acknowledgments</title><p>We thank Bridgette Wellington at ICF Macro for her assistance with accessing the study data, Rose A Lee for helping develop the preliminary AIDS case definition, and Kate Kerber at Save the Children (South Africa) for sharing information on child AIDS case definitions used in VA studies conducted in several demographic surveillance sites in South Africa.</p><p><bold>Funding:</bold> Bill & Melinda Gates Foundation.</p><p><bold>Authorship declaration:</bold> LL and REB conceptualized the study.
