Physician coding Coding by a panel of three physicians assisted with medical records and diagnostic tests Coding by one physician assisted with medical records and diagnostic tests Dual, independent coding of VA records, disagreements resolved by reconciliation, and for remaining cases by adjudication by a third physician Dual, independent coding of VA records, disagreements resolved by third physician. Single physician re-coding of VA records after initial coding by another physician.
  1. All VA data in the Million Death Study, Agincourt and Matlab studies were collected by non-medical field staff, and coded by medical staff. aThe full IHME hospital-based dataset includes 12,000 VA records from India, Philippines, Tanzania and Mexico and was released after this paper went to press; correspondence with the study team suggested these data were from Bangladesh but the full details of the 1,556 deaths are not published. bIll-defined deaths are International Classification of Diseases-10 codes R95-R99.
