HIPE - The HIPE (Hospital In-Patient Enquiry) Scheme is a computer-based health information system designed to collect medical and administrative data regarding discharges from and deaths in acute hospitals. For further information on the HIPE scheme and the data collected, please see the main HIPE page and the HIPE Instruction Manuals.
Analysing HIPE Data - Each HIPE discharge record represents one episode of care and patients may have been admitted to more than one hospital with the same or different diagnoses. In the absence of a unique patient identifier in HIPE, the unit of measurement is discharges and not patients. The records therefore facilitate analyses of hospital activity rather than incidence or prevalence of disease. HIPE does not collect data on visits to the Emergency Department or outpatient clinics.
Hospitals Participating in HIPE - Over 60 hospitals participate in HIPE. The tables generated using this reporter will contain analysis from all public participating hospitals (including a small number of long stay hospitals). For a full listing of public hospitals that participate in HIPE, please see Appendix I of Activity in Acute Public Hospitals in Ireland Reports.
Year – Year refers to the year in which the discharge occurred. For example, 2007 data relate to those discharged from hospital in 2007, even though some of these cases may have been admitted in earlier years.
Diagnosis Report – The ‘Diagnosis Report’ allows reports to be run on principal diagnosis or all diagnoses selected using ‘Other Options’.
Procedure Report – The ‘Procedure Report’ allows reports to be run on principal procedures or all procedures selected using ‘Other Options’.
All Cases - All discharges (day and in-patient).
2005 - 2007 ICD-10-AM/ACHI/ACS
The scheme used in HIPE to code diagnoses and procedures for the period 2005 - 2007 was the International Classification of Diseases, 10th Revision, Australian Modification, incorporating the Australian Classification of Health Interventions (ACHI) and the Australian Coding Standards (ACS) 4th edition, July 2004 (hereafter known as ICD-10-AM). In the respective reports, selected individual diagnoses and procedures are listed, as well as diagnoses and procedures grouped into various categories. For example, the diagnosis group ‘Infectious and Parasitic Diseases’ is reported together with a number of conditions that fall within this group (e.g. Tuberculosis, Septicaemia and HIV). For further details, please refer to the ICD-10-AM information page. Please note that the list of diagnoses or procedures within each diagnosis or procedure group is not necessarily exhaustive.
2000 - 2004 -ICD-9-CM
The scheme used in HIPE to code diagnoses and procedures for the period 2000-2003 was the International Classification of Diseases, 9th Revision, Clinical Modification October 1, 1998 (hereafter known as ICD-9-CM). In the respective reports, selected individual diagnoses and procedures are listed, as well as diagnoses and procedures grouped into various categories. For example, the diagnosis group ‘Infectious and Parasitic Diseases’ is reported together with a number of conditions that fall within this group (e.g. Tuberculosis, Septicaemia and HIV). For further details, please refer to the following documents ICD-9-CM Diagnosis Codes and ICD-9-CM Procedure Codes. Please note that the list of diagnoses or procedures within each diagnosis or procedure group is not necessarily exhaustive.
In-patient average length of stay - Mean time, expressed in days, between admission to and discharge from hospital. For the purpose of these reports average length of stay is based on in-patient discharges only.
Age – Age is calculated on date of admission and covers the following age bands; 0-14 years – includes all discharges aged less than 15 years, 15-44 years – includes all discharges aged between 15 and 44 years, 45-64 years – includes all discharges aged between 45 and 64 years, 65 years and over – includes all discharges aged 65 years and older.
Reporting of HIPE Data
It is policy within the Health Research & Information Division at the ESRI not to present cells where the number of discharges reported to HIPE is 5 or less. Such cells have been replaced by ~. Where further suppression is necessary to ensure that cells with 5 or less discharges are not disclosed, it may be necessary to suppress the cell with the next lowest number of discharges. These cells have been replaced with *. Finally, where necessary to ensure additional confidentiality, selected rows have been aggregated.
