  "validation_description": "Wabe et al, 2021The aim of the study was to evaluate the accuracy of assigned International Classification of Diseases version 10-Australian Modification (ICD-10-AM) codes for influenza by comparing with patients’ results of their polymerase chain reaction (PCR)-based laboratory tests.Although ICD-10-AM coding for influenza demonstrated high accuracy when laboratory results were received before discharge, its sensitivity was substantially lower for patients whose test results were not available at discharge. The timely availability of laboratory test results during the episode of care could contribute to improved coding accuracy.The timely availability of laboratory test results during the episode of care could contribute to improved coding accuracy.Feemster et al, 2012We used Pediatric Health Information System data and laboratory records from 3 children's hospitals to determine whether administrative data accurately identify children with laboratory-confirmed influenza.The objective of this multicenter study was to validate influenza-specific ICD-9 codes for the identification of influenza cases among hospitalized childrenAmong 23 282 inpatients, diagnosis codes for influenza detected 73% of laboratory-confirmed influenza cases, whereas <1% of patients without a diagnosis code had laboratory-confirmed influenza.Keren et al, 2006To determine the sensitivity and positive predictive value of influenza-specific ICD-9 admission or discharge codes (487.0, 487.1, and 487.8), we conducted a retrospective cohort study of all patients <21 years of age hospitalized at the Children's Hospital of Philadelphia with laboratory-confirmed influenza during 3 consecutive influenza seasons (July 2001 through June 2004)Influenza-specific ICD-9 codes assigned in a setting of routine rapid diagnostic testing may be useful for following trends. However, these codes will substantially underestimate the actual number of influenza-related hospitalization",
