  1. DATA COLLECTION BASICS Ric Marshall 10.00 - 10.45 Tuesday, 6th December 2011

  2. WHY????? • What are the data to be used for? • What observations are needed? • What data items are able to be retrieved? • How easy are they to abstract? • How consistent are they? • How comprehensive is the collection? • Are valid? - relevant to the purpose? • How reliable? - why are they recorded?

  3. Hospital funding schemes in other countries • GERMANY – CASEMIX (DRG) PAYMENT - iNEK • UK – (HRG) - PAYMENT BY RESULTS (PbR) • USA – DRG – PROSPECTIVE PAYMENT • SLOVENIA – DRG - SAME SERVICE SAME PRICE • HONG KONG – P4P • ABF = EPISODE PAYMENT =CASEMIX =PBR =PFP =DRG FUNDING ..

  6. DATA COLLECTIONS • ACTIVITY DATA COLLECTIONS • Billing • Fee for service claims datasets • episode of care datasets • ‘Morbidity’ datasets • All activity from a provider datasets • Particular specialty area data • Particular phase of care or care-type data • COSTING DATA COLLECTIONS • CLINICAL TRIALS DATA COLLECTIONS

  8. COST DRIVERS ADMITTED OR NON ADMITTED CATEGORY AGE >70 SDX CAT PROC CAT PRINCIPAL INTENTION OF CARE PRIMARY CARE TYPE DISPOSITION PDX CAT 1,2 OR 3 FUNCTIONAL SCORE <3

  9. The National Minimum Data Set • One reporting requirement multiple uses • Complex process to maintain • Stable and rigorous standards – but variable compliance • Consistent and valid for comparisons • Alternative is required DSS for payment. • Convenient to maintain with NHDD

  10. Establishing the National Health Data Dictionary • Long term project multiple users • Consensus governance complex and slow • Eg US HIPAA law • http://www.hhs.gov/ocr/privacy/hipaa/administrative/index.html • Can have special purpose variants based on and mappable to the core data.
