CP485 1 Oct 2004 DSCN 22/2004 - Data Standards: HES extraction of Out-Patient and A&E CDS data The Hospital Episode Statistics (HES) data warehouse is a record level database of hospital admissions populated by taking a sub-set of the data submitted to the NHS Wide Clearing Service (NWCS). The scope of the data warehouse has been increased to include the Out-Patient Attendance and Accident and Emergency Attendance Commissioning Data Set Types. This paper updates the supporting information in the NHS Data Dictionary about the uses of NWCS data.
CP484 1 Apr 2005 DSCN 32/2004 - Payment by Results The Payment by Results (PbR) policy changes the way funds flow between commissioners and providers of health care services in England. Through the establishment of standard national tariffs for similar types of treatments, providers will be paid on the basis of the volume and complexity of the activity they actually deliver. Payment by Results has ministerial backing. This DSCN has been sponsored by the Head of the Payment by Results. The DSCN supports 'Implementing PbR Technical Guidance 2005/06', specifically paragraphs 3.16 to 3.18 and 6.12, which can be found on the DH website:<br>PublicationsPolicyAndGuidanceArticle/fs/en?CONTENT_ID=4097993&chk=JSLwVc. For Foundation Trusts the scope of PbR includes non-elective admissions, out-patients and A&E in 2005/6. Although, for non-Foundation Trusts, these elements are outside the scope of the tariff in 2005/6, data are still required to flow to operate PbR in shadow form and so that new baselines can be established for 2006/7. Payment by Results also requires the implementation of DSCNs 26/2003 and 34/2003 Updated National Specialty List (introduction of new Treatment Function codes). The outpatient tariff is based on Treatment Function and certain Treatment Functions are also used to define the scope of the Admitted Patient Care tariff.
