Information to Support Practice Based Commissioning SEPHIG 10/11/2008

The Hampshire Clinical Data Repository Clinical Data Repository contains: –GP records Read codes and values –Hospital Letters/ Pathology reports/ Radiology reports/ PAS –Additional clinical records OT and SAP Cancer MDT record

GP Record (Read codes) (c800,000) Hospital records Pathology Radiology Correspondence (c 8 million documents) Clinical Data Repository (CDR) OT/CN/ PT/Pod SAP Clinical view Analytical Clinical Data Repository (ACDR) IP/OP/A&E CMDS (Other data sets?) Care Pathway Reports Prevalence GP and hospital activity Clinical outcome CDR Patient Index EXETER NHS REGISTER

Analytical data repository Includes Commissioning data sets A&E Outpatient In patient/ day case Potential for other data tables ( e.g. Cancer MDT, Single Assessment, OT record etc)

Volumes 7.6 Million documents from SUHT/PHT on 696,000 patients 160 Million GP record entries on 850,000 patients 282,000 of 1.26 million patients have both hospital and GP data 200 users making 12,000 record accesses/ month

What’s the USP of the CDR? Clinical Support: –Web based shared clinical record –Up to date and accessible wherever patient is seen –Read only and writeable forms Analysis –Across the whole pathway of care Primary  Secondary  Tertiary  Primary –Detail of process of care Pathology tests, medical imaging, referral –Detail of clinical severity Biochemistry/ Haematology/ Blood Pressure / Spirometry

GP records Flat file: Date of entry Read Code Read code text Code Value(if appropriate) Code Units(if appropriate) NHS Number (encrypted)

Hospital records Portsmouth: (16 feeds) –Haslar –Queen Alexandra Imaging/ Medical Physics/ Biochemistry/ Haematology/ MAU discharge Southampton (13 feeds) Imaging/ Biochemistry/ Haematology

CMDS feeds Extracted from PCT systems monthly as flat files (patient identifiers excluded/ encrypted) A&E Out patients In patient/ day cases

Pseudonymisation NHS Number encrypted Post Code converted to Output area Tables to have cells with values less that 3 suppressed

Development of Reports Care pathway based: –Single pathway points How many Diabetic patients have HbA1c/ BP/ Cholesterol in last year How many patients have HbA1c below X/ BP below x/y, cholesterol < x etc –Whole pathway How many patients meet all pathway criteria for –Diagnostic work up –Annual monitoring –Assessment of complications

Development of reports(2) Analysis of episodes of care: Link events over time for individual patients Calculate annual costs of diagnostics/ treatments

Diabetes Care Pathway Objectives Identify key steps in delivery of care Identify ways to measure success at these key steps Identify the reports required to measure

Diabetes Diagnosed Initial assessment Routine monitoring of diabetes and management of risk factors Management of complications RenalOphthalmicCardiacVascularNeurologicalPregnancy Prioritisation of Potential Indicators
