| Résumé : | [BDSP. Notice produite par INIST-CNRS 9tJR0x6F. Diffusion soumise à autorisation]. To determine the completeness of reporting of human immunodeficiency virus (HIV) diagnoses to state surveillance systems, the authors used capture-recapture methods. The numbers of cases diagnosed in the areas were estimated using HIV diagnoses reported to nine surveillance programs by different sources (e.g., laboratories, health-care providers). To account for dependencies between reporting sources, the authors used log-linear models to estimate the number of cases that had been diagnosed but were not identified by any reporting sources. Completeness of reporting (observed cases/expected cases) was determined for two time frames : cases diagnosed within a 1-year period (from October 1,2002, to September 30,2003, for most US states) reported up to 6 months after that diagnosis period and cases diagnosed within a 6-month period reported up to 12 months after that diagnosis period. A total of 11,266 HIV diagnoses were reported for the 1 - year period with 21,589 report documents. Completeness of reporting of HIV diagnoses was 76% (95% confidence interval : 66,83) when allowing 6 months of reporting delay (range : 72-95%) and improved to 81% (95% confidence interval : 72,88) with 12 months'follow-up. When reporting systems retain all relevant documents, capture-recapture is a feasible approach for assessing completeness of reporting of HIV diagnoses. Completeness should be measured by allowing 12-months'reporting delay. |
