Comparison of Lab Data to Hospital Discharge Abstracts and Medical Services Data

    Incident HIV cases identified from the hospital abstracts data and medical services data were compared to the CPL data for the fiscal years 2007/08 and 2008/09. ICD-9-CM codes 042 and ICD-10-CA codes B20-B24 were used to identify the diagnoses of HIV. In the two-year period, a total of 203 new cases of HIV were identified in the hospital abstracts and medical services/physician claims data. Of these cases, 33.0% had a positive HIV test result in the CPL data 30 days before or after the diagnosis date. When a 180-day period was used, 45.8% had a positive test in the CPL data, indicating a moderate agreement between positive test results and diagnoses for HIV in hospital abstracts and medical services/physician claims data. For more information on how HIV was investigated in the CPL data, read the section titled Case Study #1: Record Linkage for HIV Tests in Lix et al. (2012).
