This is the fifth publication in Series 11, which replaced Series 4 after its discontinuation in 2003. The introduction of Series 11 coincides with the 2005 reformulation of the Health Service Statistics Subsystem, which generates the inpatient morbidity statistics within the Health Statistical System.

The report provides discharge data from public sector, inpatient care facilities for 2008. National university facilities and those in the private and social insurance fund sectors are not included in the data. Armed forces facilities were incorporated into the statistical system in June 2008, but it is unclear when this data began to be included in reports. Diagnoses are coded in ICD-10 and grouped into 80 categories. The data are broken down by province, sex, and 5-year-age groups, and represent a single, principal diagnosis for each period of hospitalization.

Data from the province of Santiago del Estero are not included for 2008. The report provides further details on coverage gaps.
