Introduction TheWorldHealthOrganization (WHO) standard verbal autopsy (VA) instrumentwaspublished in 2007 and has been successfully applied inmany research settings sincethen. Inrecentyears, therehasbeengrowinginterest instrengtheningcountries’civilregistrationandvitalstatistics(CRVS)systems,andthishasledtodemandforamoresimplifiedandpracticalVAinstrumentandassociatedITapplicationsfordatacollectionandanalysisthatcanbeusedroutinelyaspartofthecivilregistrationsystem.Inresponse,ameetingtoreviewtheWHOVAinstrumentswasorganizedbytheWHODepartmentofHealthStatisticsandHealthInformationSystemsandtheHealthMetricsNetwork (HMN), in collaboration with the University of Queensland (UQ) and theINDEPTH Network. Themeeting took place on the 19 and 20 of December 2011 atWHO, Geneva, Switzerland, and was attended by 37 participants from 15 countries.Participants included key stakeholders, researchers and those who work day to daywithVAtools.Adetailedlistofparticipantsandtheirrespectiveinstitutionalaffiliationscan be found in Annex 1. Themeetingwas followed by a two day workshop duringwhich a small group consolidated the outcomes of the discussions and prepared thefinaloutcomesdescribedinthisreport.

The next step involved thepresentationofevidenceforaproposedlistofindicatorstobeincludedinthesimplifiedVAinstrument.Afinallistwasdiscussedinplenaryandcomparedwithindicatorsthatemerged following an item reduction undertaken by the Population Health MetricsResearchConsortium(PHMRC)usingtheTariffmethod,asimpleadditivealgorithmforanalysisofVA. Theresultsofthesediscussionswereconsolidatedbyasmallworkinggroup in the two days following the main meeting, and assessed for suitability insoftwaretools.

Opening The meeting was formally opened by Dr. Ties Boerma, Director, Department ofMeasurementandHealth InformationSystemsatWHOandcollaboratingpartnersDr.Alan Lopez, School of Population Health at the University of Queensland, Dr. OsmanSankoh, Executive Director at INDEPTH Network, and Dr Marc Amexo of the HealthMetricsNetwork.In summarising experiences in the use of the standardWHOVA instrument since itsinception it was pointed out that VA has been used mainly in research settings.However, demand is growing for simplified and shorter VA instruments that can beused to ascertain causes of death routinely in civil registration systems. This wouldgenerate statistics on patterns ofmortality in settings wheremedical certification ofcauseofdeathisnotwidelyavailable.Itwasacknowledgedbyallparticipantsthatthedevelopment of a simplified VA instrument should be based on strong evidence offeasibilityandeffectivenessandshouldtakeintoaccounttheneedsofusers, includingatlocallevels.There was agreement that the accurate determination of CoD at the level of theindividualrequiresexaminationbyamedicallytrainedpersonfamiliarwiththerulesofthe International Statistical Classification of Diseases and Related Health Conditions,10thRevision (ICD10). However,whilemedical certificationof CoD is considered the“goldstandard,”inpracticerelianceonclinicaljudgementaloneisofteninsufficientandneeds to be supplemented by diagnostic tests and medical autopsy. Verbal autopsytechniques cannot attain the levels of accuracy and precision in individual CoDascertainment thatarepossibleusingphysiciandiagnosis. Instead, thepurposeof themeetingwastodevelopaVAinstrumentthatwouldbesufficientlyrobusttogeneratereliableCoD information at thepopulation level andproduce cause‐specificmortalityfractions through the application of automated diagnostic methods such as machinelearning.Dr. Sankoh pointed out thatmuch of the long‐term experience in the use of VAwasthrough health and demographic surveillance sites (HDSS) established as part ofbroaderresearchefforts.Manyof theseHDSSsitesarepartof theINDEPTHNetwork.HehighlightedthecentralimportanceofVAfortheINDEPTHNetworkandpointedoutthatprior to thedevelopmentof theWHOVA instrument in2007,manyof theHDSSsites had been using different instruments, thus reducing the temporal and cross

sectoral comparability of the results. Dr. Sankoh informed that all INDEPTH sites areusingthe2007WHOVAinstrument.

HMN MoVE IT initiative Dr.Mark Amexo introduced the HMN priority strategic initiative,Monitoring of VitalEvents,includingthroughtheuseofInformationTechnology(MOVE‐IT).Thisinitiativeaims to improve the monitoring of vital events and strengthen country informationsystems through innovation and use of information technologies. He described thegrowing political commitment and institutional support for improvement of civilregistration and vital statistics systems, and the high demand for tools to permit theproductionofimproveddataonCoD.HMNhasbeencollaboratingwithWHOtodevelopstandards and instruments that facilitate collection, analysis and reporting ofpregnancy,birthanddeathdata.Fordatacollection,anautomatedVAinstrumentwillbringneededinnovationincivilregistrationandstatisticssystems.Participantscommentedthat thatgenerationofevidence fordesigningand improvinginstruments takestime.The implementationofautomatedVAinstruments inthe fieldneeds to take into account also issues of coordinating the necessary infrastructure,identifyingrelevantstaff,andselectingadequatesoftwarecompanies.

Revising the WHO VA instrument and its uses Dr.Daniel Chandramohanpresented the preparatoryworkwhich compareddifferentVAinstruments,includingthosedevelopedbyWHO,theINDEPTHNetwork,theSampleregistrationandverbalautopsy (SAVVY) instrumentdevelopedbyMEASURE, and theVA instrument developed by the London School of Hygiene and Tropical Medicine(LSHTM).Atotalof368publishedVAstudieswerereviewed,ofwhich98notedtheuseoftheVAinstrumentsofinterest.However,themajorityofstudiesdidnotreportwhichVAinstrumenthadbeenutilized.Fromthereview, itemergedthatthemost frequentlyusedVAinstrumentshavebeenthe WHO VA instrument and its adaptations, followed by the INDEPTH VA and itsadaptations,theLSHTMVAanditsadaptations,andtheSAVVYtoolanditsadaptations.Intermsofgeographicaldistribution,relevantVAstudieshavebeenmainlyconductedinAfrica(55%)andAsia(36%),withasignificantlysmallernumberofstudiescarriedoutinCentralandSouthAmerica.ApostalsurveywasconductedamongresearchersknowntohaveusedVAtechniquesto identifywhichquestions generated themost reliable information inVA interviewsandwhichmodificationshadbeenmadetoVAinstruments,andtoascertainthemostimportantquestionsforCoDascertainment.Atotalof27VAuserswerecontactedand10responded.AlldescribedthequestionsincludedintheWHOVAinstrumentasusefuland reliable but mentioned that a shorter andmore simplified instrument would beeasiertoimplementinthefield.Themajorityoftheresearcherswhorespondedcouldnot identifywhich questions provided themost reliable and relevant information forCoDascertainmentorwhichquestionscouldbedropped.

The need for physician review of completed VA questionnaires was described asresource intense and time‐consuming.Moreover, themethod is subject to significantvariability between coders, across sites and over time. Respondents and a literaturereview confirmed that someof theCoD included in theWHOVACoD list have rarelybeencertifiedfromVA.Discussion:

ThereisdemandforsimplifiedVAinstrumentsforuseinroutinedatacollectionsystems; automated CoDmethods are feasible, and the results from validationstudiesofsuchinstrumentsarepromising.

Thereisverylimitedevidenceabouttheutilityofindividualquestions. ThereisevidenceaboutuseandfeasibilityofspecificCoDinVA. The contribution of VA to global mortality estimates is unknown but in non‐

medicallycertifieddeaths,CoDinformationcanbecollectedwithVA. Open narrative input on VA questionnaires is not necessary for automated

systems,butitisessentialforphysicianreview. The VA questionnaire should be designed to be usable by physicians and

automated systems,but the aim is tomove away fromphysician reviewofVAquestionnaires.

Experiences with VA and InterVA for cause‐of‐death determination Dr.PeterByassintroducedtheALPHAnetwork,acollaborativenetworkfortheanalysisofpopulation‐basedHIV/AIDSdatainAfrica.TheALPHAandINDEPTHnetworksworkcloselytogetherandshare8/10centres.ThecollaborationlargelydrawsonInterVAfortheassessmentofcausesofdeath.InterVA is software that uses input to a set of dichotomous questions followed by aBayesian approach for interpreting the responses. It uses a priori estimations ofprobabilities related todiseasesand symptoms to calculate theprobabilityof specificCoD.ItwasemphasizedthatInterVAisnotanalgorithm,butamodel,withprobabilitiesinformedbyseriesofconsultationswithpanelsofphysiciansandadjustmentwithdatafromthefield. ThelatestInterVAmodelversion, InterVA‐4β,combinesInterVA‐3andInterVA‐M(Maternal).InterVA is robust; it is not sensitive to small variations in probabilities. A study hadassessed the extent of InterVA’s ability to characterize population mortalitycompositionusingdifferentaprioriprobabilities.Thecausespecificmortalityfractions(CSMF)weresimilarbetweentheoriginalInterVAmodelandthemodelswithmodifiedaprioriprobabilities.ThedurationofVA interviewswithInterVAmakesVA feasible inroutineuse. Apilotstudy in Indonesia showed that in average it took 11 minutes to carry out a VAinterviewwith80itemsusinghandhelddevices(InterVA‐M,excludingintroductionandthanking).Dr.ByassproposedtheinclusionintherevisedVAinstrumentofacoresetof key background questions that would provide information about the context ofdeaths.Discussion

In a short VA instrument for routine use, the accuracy in assessing a CSFM ismoreimportantthanascertainingtheCoDatindividuallevel.

Population Health Metrics Research  Consortium  (PHMRC): Use of Gold Standards in Studying the Validity of Verbal Autopsy Methods Dr.IanRileypresentedthePHMRCstudyongoldstandardVAvaliditythatwasfundedas part of the Bill &Melinda Gates Foundation Grand Challenges in Global Health toInstituteforHealthMetricsandEvaluation,JohnsHopkinsSchoolofPublicHealthandUQ.Thestudycommencedin2007andcompleteditsdatacollectionin2011inAndhraPradesh,India,UttarPradesh,India,Bohol,Philippines,DaresSalaam,Tanzania,PembaIsland,Tanzania,andMexicoCity,Mexico.The gold standard VA validity study aimed to overcome common issues affecting VAvalidationstudies,suchasthelimitednumberofcausesofdeathassessed,thequalityofmedicalrecords,andthediagnosticcapacitiesofhealthfacilities. InmanyVAstudies,metricsofsuccessactuallyrelatetoconvergentvalidity(comparisonsofVAcauseswithphysiciandiagnosisofcauseofdeath)ratherthanconstructvalidity(comparisonwithagoldstandard). Thepurposesofthestudyweretodevelopcomprehensible,objectivevalidation standards independent from physicians, and to compare computer drivenanalysis of symptom patterns against diagnoses that had been ascertained in healthfacilitiesandthatwerecompliantwithasetofdiagnosticproceduresandresults thatweredeterminedbyagroupofexperts(goldstandarddiagnoses).AtargetCoDlistforadults,childrenandneonateswasdevelopedandderivedfromtheGlobal Burden of Disease (GBD). Subsequently, diagnostic criteria were defined toestablish “gold standards” for each CoD, and corresponding deaths in participatinginstitutions that met “gold standard” criteria were selected. The VA was conductedusing a modified version of the WHO VA instrument. The PHMRC VA instrument iscomposedof3modules: general informationmodule,neonatal andchildmodule, andadultandadolescentmodule. InpreparationofthePHMRCtool,170differenceswereidentified between the WHO and PHMRC VA instruments, including among others,addition and deletion of certain chronic diseases, differences in terminology andremovalofsomequestions.Dr.Rileydescribedtheanalyticalprocedureinvolved invalidatingtheperformanceofthemethod. First, the dataset is randomly split into two sets, namedTrain and Test;second, the deaths in Test set are resampled to have 1000 deaths; and third, thealgorithmistrainedonthedeathsintheTrainset,andtheperformanceofthealgorithmis assessed by predicting the CoD for the deaths in Test dataset. This procedure isrepeatedover500times.Forthistobevalid,itisnecessarytohaveatleast20deathsper CoD.

again.

Brazil Dr. Elisabeth França introduced the Mortality Information System (MIS) from Brazil. In 2003, it had a high coverage (87%) with a high proportion of medically certified CoD in the South and Southeast regions but a low coverage in North and Northeast regions. Data were shown on the proportion of ill-defined CoD in Brazil from 1996 up to 2004. Between 2004 and 2008, the MoH did systematic research of non-registered deaths with the project “Reorganization and qualification of health information systems”. To introduce VA instruments into the investigation of ill-defined CoD occurring at home, a study was conducted in 2007/2008 in three phases, first adapting the VA instrument in use in Mozambique (SAVVY) and testing it in one urban and one rural area, and presenting it to 15 priority states (n=25). After review, a second test was carried out in the selected 15 states (n=271). Upon satisfactory completion, in a 3rd round, 14 states participated in a pilot study with a total of 1444 cases investigated.

Differences and modifications made to the SAVVY instruments included: Different structure of age groups: under 1 year old, from 1 to 9 years old and 10 years

old and above; Data abstracted from health records and from the death certificate were not included

in VA instruments, but were captured by extra forms used in addition to the VA questionnaires; and

Questions that were removed from the SAVVY instrument related to history of injuries/accidents, signs and symptoms noted during the final illness, as cough severity, ability to open mouth, having red eyes.

The resulting version of the VA instrument was implemented throughout the country in 2009, as routine procedure in the MIS for the investigation of ill-defined deaths occurring at home, and as supplementary information for the assessment of maternal and infant deaths in home interviews. The VA has been routinely implemented as part of the Epidemiology Surveillance activities and also within the Family Health Program with teams (1 team/3500 people) that include 1 doctor, 1 nurse, 3 nurse assistants and 5 community workers. VA data interpretation and CoD assignment is carried out by physician review, and follows ICD-10 rules. Advantages of using physician review include synergies with promotion of health strategies at the local level and possibility of training of physicians in certification of CoD. The introduction of VA resulted in decline of the proportion of ill-defined CoD. Dr. Franca informed that a pilot phase of an evaluation project was implemented in 2011 and the global project is planned for 2012. Challenges of using VA in routine surveillance are the additional workload for health professionals, lack of qualified staff, and lack of funding.Discussion:

Questionsonsensitiveorstigmatizingtopicsmaynotprovidereliableanswers.Thismaybeparticularlytrueforsuicideinreligioussettings.

The open narrative may be the best way to attain information on culturallysensitivecircumstancesrelatedtoCoD.

Questions on sensitive topics should be included but rephrased in a way thatwouldnotoffendorintimidatetherespondent.

WhereVAbecomesaninstrumentforroutineuseandinformationoftheMoH,itis important to have questions on the context of the death (e.g. health systemuse).

Papua New Guinea Dr. IanRileydescribedtheexperiences inthedevelopmentanduseofasimplifiedVAinstrument in Papua New Guinea (PNG) highlands in 1970/71. The instrument wasdeveloped in order to provide endpoints of trials of pneumococcal polysaccharidevaccine against pneumonia in adults and children; and to add to data from smallpopulationstudiesofmortality,whichhadrunfrom1949throughthe1960s.TheVAinstrumentwastargetedforthespecificcontextofthePNGhighlands.Severaldiseaseswerenotincluded,suchasmyocardialinfarctionandlungcancer.Incontrast,unusualdiseaseswerecommonintheareasuchas“pig‐bel”andaformofchroniclungdisease. The instrument was very simple because the questions targeted the specificepidemiological context and due to the high level of illiteracy and absence of on‐sitecomputers. To classify theCoD, theWHOLayReportingClassificationwasusedwithsomerefinement forbetterapplicationto thePNGHighlandsdiseasepattern.

It is important for VA instruments to target the communities they are beingappliedto.

Qualitycontrolproceduresneedtobeimplemented. Opennarrativesectionshouldalwaysbeassessedagainstspecificquestionsfor

consistency.

Item Reduction from INDEPTH Sites Dr. Byass briefly shared some outcomes on the utilization of VA instruments inINDEPTHsites.Results fromseveral INDEPTHsiteshaveshownthat theextractionofsmall subsets of closed‐question data from longer VA questionnaires and theirinterpretation via probabilistic models leads to accurate CoD assignment. Longquestionnaires and physician review are time consuming, involve high costs and arehumanresourceintensive.Discussion

Item reduction of the PHMRC Instrument Dr. Hernandez presented a comparison between VA instruments used in the field(General Registrar of India, SAVVY andWHO) and the PHMRC VA instrument.

Dr.Hernandezencouragedtheuseofnewmetricsthatprovidemorerobustinformationon CoD ascertainment and CSMF estimation, and that are less sensitive to the causecomposition of the test sample. Chance‐corrected concordance across causes wasexplainedandrecommended forassessinghowwellamethoddoesat individualCoDassignment.FortheevaluationofCSMFestimation,CSMFaccuracywasproposedasameasure independentof thenumberofcauses.Medianchance‐correctedconcordancevalues using Tariff as compared to physician certified VA (PCVA) including andexcludinghealthcareexperience(HCE)wereshown.TheTariffmethodscoredhigherchance‐corrected concordance values than the PCVA for adult and neonatal deaths.PCVA scored higher chance‐corrected concordance values for child deaths. Anotherinteresting point was that the performance of both methods was similar with theinclusionofHCE,buttheefficacyofthePCVAexcludingHCEdecreasedsignificantlyincomparisontotheTariffwithoutHCE.TheitemreductionprocessbasedontheTariffMethodconsistedof:

1. SelectingitemstobedroppedbasedonTariffscore;2. AssigningCoDbasedonTariffmethod;and3. Assessing performance based on chance‐corrected concordance and CSMF

accuracy.Dr. Hernandez showed the results of the progressive reduction of symptom‐relatedquestions from 100 to 20 in adults without HCE information, and the reduction ofsymptom‐relatedquestionsfrom60to50inneonateswithHCEinput.HealsoshowedthattheperformanceoftheVAinstrumentdecreaseswiththenumberofquestions.Heconcluded that good performance levels could be achieved by using shorter VAinstrumentswithincertainlimits.Datapresentedshowedthatforadults,reducediteminstruments performed better than a complete version of the PCVA questionnaire,althoughnotaswellasPCVAwithHCE.Forchildren,overallperformancewas lower,althoughremovingupto22%ofitemsstillachievedbetterperformancethancompletePCVAordeathcertificates.The presentation concluded with Dr. Hernandez highlighting the contribution andusefulness that shorter VA instruments can have, and stressing the tension betweenquality,resourcesandcoverageduringtheitemreductionprocess.Discussion

Simplified questionnaire AreducedquestionnairewaspreparedprevioustothemeetingbasedontheWHO2007VA instrument,with indicators’ reduction informed by the reduced list of conditions,PHMRC VA instrument, InterVA indicators and VA studies. However, the availableevidenceon relevanceof specificquestions frompublishedVAstudies is very limited(backgrounddocument4).Thiswasconfirmedbythepresentationsandinthefollowingdiscussions.Toreviewtheproposedsimplifiedquestionnaire, themeetingparticipantssplit into4groups(adult,children,neonatal,maternal)andreviewedthequestionnairesbearinginmind:

Modificationsmadeincludedtheremovalofoverlappingindicatorscapturingthesameinformation,andsomechangesinterminology;

The majority of questions removed were sub‐indicators specifying duration,severityanddevelopmentformofsignsandsymptoms;

From the review of the outcomes of the Tariff item reduction exercise it wasverified that some of the duration‐related indicators are needed to qualifycertainindicators,eveniftheyarenotveryrelevantbythemselves;

The proposed background social questionswere found to be too complex andunreliable. Itwas agreed that further investigation and assessment of these isrequiredbeforeagreeingonacoresetofbackgroundsocialquestions;

As a next step, indicators need to be phrased into answerable questions, andhaveclearexplanationsfortheinterviewersandtranslators.
