Top 10 Principal Procedure Blocks for primiparous and multiparous delivery discharges with a principal procedure reported. Delivery relates to women with a diagnosis of outcome of delivery (ICD-10-AM – Z37) in acute public hospitals with an allocated admission type of Maternity only. HIPE collects the number of previous live births and number of previous stillbirths (over 500g) for all cases with admission type code Maternity. Primiparous: These are women who have had no previous pregnancy resulting in a live birth or stillbirth. Multiparous: These are women who have had at least one previous pregnancy resulting in a live birth or stillbirth. Activity in Acute Public Hospitals in Ireland Annual Report, 2014, is a report on in-patient and day patient discharges from acute public hospitals participating in the Hospital In-Patient Enquiry (HIPE) scheme in 2014. Discharge activity is examined by type of patient and hospital, and by demographic parameters (such as age and sex). Particular issues of relevance to the Irish health care system covered in the report relate to the composition of discharges by medical card and public/private status. Discharges are also analysed by diagnoses, procedures, major diagnostic categories, and diagnosis related groups. Maternity discharges are examined separately from other discharges. The analysis is presented at the national level. In 2014 HIPE discharges were coded using ICD-10-AM/ACHI/ACS 6th Edition and grouped into AR-DRG Version 6.0.
