This overview explores the challenges and dilemmas posed by mergers in multi-site healthcare systems, specifically focusing on RIS/PACS systems and cancer networks. It also discusses the need for standardizing codes and the role of national agreements in streamlining workflows.

The issues (mergers) • To date most of us have thought about single hospital RIS/PACS • Mergers bring dilemmas • Different philosophies • Changing perspectives • Long term planning change • Multiple IT systems • Commercial issues

The issues (clinical networks) • Cancer networks cover three or more Trusts • Need to move images • How? • Security and encryption issues • Point to point • WAN - ?role of StHA • Web based systems • Based on one PACS • Or de-novo setup

Example -Upper GI IOG • Initial diagnosis and staging at Cancer Unit (Hastings / Eastbourne / Worthing / Haywards Heath) • Discuss with UGI surgeons at UGI Cancer Centre (Brighton) • Yes ? Sx :Transfer patient for assessment No Sx : Keep patient at Unit • Discuss with Centre assessment and treatment plan • Unit for chemotherapy / palliation
Information gathered at initial presentation and diagnosis plus local staging History Clinical examination Endoscopy Histopathology CT/CXR/Ultrasound Abdo ECG/Spirometry Text General Condition of Patient Images Tumour Type TNM Text

The issues (national) • Many different RIS • Standardising short codes • IHE • SNOMED codes • Role for RCR group ? • If we need to move images around the country we really should be considering single descriptors
The issues (national) • Many different RIS • Not much can do about this • New PSPs may start to rationalise • But ? Engulfment in whole EPR • Part of new PACS?
The issues (national) • Standardising codes • National agreement on codes via RCR – unlikely? • SNOMED codes – how far away are they? Are they relevant to workflow control or just diagnostic codes • IHE – DICOM/HL7 transactions • 3 types of code • Order Code (ie what requesting clinicians recognise as a RIS code e.g. for Barium Enema • Requested procedure codes (ie for the resource requirement e.g. for a Barium Enema) • Which may contain one or more Protocol codes (defined to organise the radiographers work – in the case of a Barium Enema the fluoroscopic and CR/DDR elements
The issues (national) • Role for RCR group ? • If we need to move images around the country we really should be considering precise descriptors • Go with IHE and let BIR lead in UK, but have RCR PACSgroup input ?
The issues (national) • Another role for RCR group ? • National Radiology messaging project • NHSIA initiative, for implementation end 2003 • Specification and delivery of a list of agreed codes for use in electronic reports to GPs
