Summary
Improving identification of acquired immunodeficiency syndrome (AIDS) hospitalizations in administrative data is crucial. This study refined methods and found AIDS reporting completeness varied by demographic subgroups.
Area of Science:
- Public Health
- Epidemiology
- Health Informatics
Background:
- Accurate identification of hospital discharges related to acquired immunodeficiency syndrome (AIDS) is essential for surveillance and resource allocation.
- Administrative databases offer a broad view of hospitalizations but require refinement for specific disease identification.
- Understanding reporting completeness is vital for assessing the true burden of AIDS and identifying disparities.
Purpose of the Study:
- To enhance methods for identifying human immunodeficiency virus (HIV)-specific and AIDS-related hospital discharges within administrative databases.
- To evaluate the completeness of AIDS case reporting in Massachusetts, examining overall rates and subgroup variations.
Main Methods:
- Utilized fiscal year 1988 discharge data from the Massachusetts Rate Setting Commission (RSC) and the Massachusetts AIDS Reporting System (ARS).
- Developed and tested diagnostic code sets (HIV-specific codes 042.x, 043.x, 044.x, 795.8, and AIDS-defining manifestations) to identify relevant discharges.
- Reviewed medical records of patients identified in administrative data but not reported to the ARS to assess reporting accuracy.
Main Results:
- A refined set of diagnostic codes achieved 93% sensitivity and 86% specificity for identifying AIDS-related discharges.
- Out of 927 identified AIDS cases from discharge data, only 36 were not reported to the ARS, indicating high overall reporting.
- Unreported AIDS cases were significantly more likely among women (OR=2.9), intravenous drug users (OR=4.2), and individuals outside the Boston metropolitan area (OR=2.3).
Conclusions:
- Improved diagnostic coding strategies can significantly enhance the identification of AIDS-related hospitalizations in administrative datasets.
- While overall AIDS reporting completeness is high, specific demographic groups, including women, intravenous drug users, and those in non-metropolitan areas, are at higher risk of underreporting.
- Targeted interventions are needed to address reporting gaps in vulnerable populations to ensure comprehensive AIDS surveillance.

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
