Subject Keywords: Age-standardised Data All recorded Procedures (principal procedure and up to 19 secondary procedures)
Catalogue: Data
Secondary Data Sources - Indicator Sets
Type: Table
Region: Republic of Ireland
Description:

The data reported in this table are derived from the HIPE (Hospital In-Patient Enquiry) data set, which records data on discharges from all publicly funded acute hospitals. Age-standardised discharge rates by county, sex and all procedures are presented. These allow comparison of discharge rates between populations of different age composition, and also of discharge rates over time. The age-standardised discharge rate (SDR) for an area is the number of discharges (per 100,000) that would occur if that area had the same age structure as the WHO European Standard Population and the local age-specific rates for that area applied. Confidence intervals for these rates are also presented.

Standardised Morbidity Ratios (SMRs) are also included. SMRs express the difference between the observed discharges in each county compared to the expected discharges if the age-specific rates of the national population applied. It is presented as a ratio. A ratio that is greater than 100 indicates that county experienced higher discharges than would be expected. A ratio of less than 100 indicates that county experienced lower discharges than would be expected. Confidence intervals for these rates are also presented.

 This table covers the years from 2005 to 2011. Data are classified by procedure categories. The HIPE system includes a principal procedure and up to 19 secondary procedures. All recorded procedures are counted in this table. The procedure categories are based on the ICD-10-AM classification. From 1st January 2006 the HIPE system has been collecting data relating to patients admitted for dialysis in dedicated dialysis units. These episodes were previously excluded from HIPE. This data is being collected in order to provide national data regarding the volume of patients receiving dialysis. The inclusion of this activity has resulted in a significant increase in ‘1100 – Procedures on Urinary System’ and ‘1102 – Haemodialysis’ in 2006 and subsequent years. Also in 2006, the HIPE system was amended to facilitate improved coverage of radiotherapy activity. This has resulted in a significant increase in ‘1800 – Radiation Oncology Procedures’ and ‘1801 – Megavoltage Radiation Treatment’ in 2006 and subsequent years. Both the improved coverage of radiotherapy and the inclusion of dialysis activity have resulted in a substantial increase in ‘0- All Procedures’ in 2006 and subsequent years compared to 2005.

NOTES:

1. SMRs and SDRs based on a small number of cases should be viewed with caution. Similarly, confidence intervals based on less than 50 cases should be viewed with caution as larger, less exact confidence intervals are produced.

2. The SMRs presented cannot be used to compare counties with each other, as each county’s population structure weights the age-specific morbidity rates differently.

3. It should be noted that persons who are hospitalised several times during the course of the year are recorded in the statistics for each episode of hospitalisation. For these and other reasons, the data should not be used as a proxy for prevalence. It provides indicators of public hospital utilisation and should be interpreted in this context.

4. Discharges from private hospitals are not included.

5. Data relating to non-residents are not included in this table.

6. For historical reasons a small number of non-acute hospitals are included in HIPE. This activity represents a small proportion of all activity in HIPE.
