^a Includes principal and secondary HIV hospitalizations. Principal HIV hospitalizations are hospitalizations with a principal diagnostic code (ie, the first-listed diagnosis) with International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) HIV codes 042, 079.53, or 795.71 indicating that a patient was hospitalized because of a complication of HIV infection.¹¹ Secondary HIV hospitalizations are hospitalizations with an ICD-9-CM HIV code as any non-principal diagnostic code.

^b Excluded were 332 hospitalizations in which the patient’s ZIP code indicated that the patient did not reside in Illinois. Data sources: Illinois Department of Public Health hospital discharge data¹⁰ and Illinois HIV surveillance data 2008-2014.¹³

^c Unclassified hospitalizations represent various diagnoses that do not fit into other Agency for Healthcare Research and Quality Clinical Classification System (CCS) categories and that have been grouped together into 1 CCS category.¹⁷
