As part of ALPHA, all partners are being asked to provide their VA data (all ages) alongside any physician review data available, residency data and HIV data for secondary analysis to address the following objectives: \n\n(i) Preparing VA data in a standardised format, and comparing sex- and age- specific cause-specific mortality fractions across different ALPHA partner study areas   \n(ii) Assessing the performance of automated methods for assigning causes of death based on verbal autopsy data, against physician review or HIV sero-survey data (where each of these data sources are available)\n\nOnce these secondary data have been shared with the ALPHA team, we will check the data for consistency and integrity and clean them with the help of the owners of the data and merge the clean data to form a pooled data set.  In collaboration with the team at The Ohio State University, we will prepare distributions of deaths by causes using automated methods, and calculate the cause-specific mortality fractions and rates stratified by key socio-demographic characteristics of the population and look at how they change over time. The performance of automated methods will be assessed in comparison to physician review assignment of cause of death or HIV sero-survey data. These results and outputs will be shared with each partner, with opportunity to provide input, and be involved with writing any papers.","coll_dates":[{"start":"2000-01-01","end":"2020-12-31","cycle":""}],"nation":[{"name":"South Africa","abbreviation":"zar"}],"geog_coverage":"South Africa","geog_unit":"Village","analysis_unit":"Each observation describes either an individual or an individual's period of residence in a household.","universe":"Household members of the Africa Health Research Institute Population Intervention Programme Study Area","data_kind":"Surveillance Data"},"method":{"data_collection":{"data_collectors":[{"name":"Africa Health Research Institute","abbreviation":"","affiliation":""}],"sampling_procedure":"Household demographic Surveillance","coll_mode":"Face-to-face [f2f]","research_instrument":"The original unharmonised data was collected by the Africa Health Research Institute","coll_situation":"ALPHA data are harmonised datasets from ALPHA member sites and this dataset  is from the Africa Health Research Institute."}},"data_access":{"dataset_availability":{"original_archive":"Karonga (MW011)"},"dataset_use":{"contact":[{"name":"DataFirst","affiliation":"University of Cape Town","email":"support@data1st.org","uri":""}],"conditions":"Licensed access data, available under conditions"}}},"schematype":"survey","tags":[{"tag":"ALPHA"},{"tag":"NIH"},{"tag":"Verbal-Autopsy"}]}
