This is the seventh 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 that generates the inpatient morbidity statistics within the HMIS.

The report provides discharge data from public sector, inpatient care facilities for 2009. 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 Entre Rios are not included for 2009. The report provides further details on coverage gaps.
