Manchester Case study: MIU Minor Injury Units: replacing "unviable" accident & emergency departments nurse led deal with "straight-forward" problems Linked to central A&E department by video link to provide expert backup Examples: Cornwall Portsmouth/Gosport

Manchester Cornwall MIUs

Manchester Gosport MIU

Manchester Case study - ambulance links ECG, etc. links from ambulance to hospital Expert backup for paramedics Reducing "call to needle" time for rural heart attack patients Dundee study reduced average time from 125 to 52 minutes [Pedley et al; BMJ 2003] Also, advance warning to A&E staff of details of incoming cases

Manchester Dundee trial

Manchester Case study - MDTs Multi-disciplinary teams (e.g. in cancer care) need to discuss patient cases Travel costs (i.e. time) prohibitive Video-conference links allow staff to meet at more frequent intervals

Manchester East Midlands cancer network

Manchester Case study - teledermatology Overload on specialist dermatologists - long waiting lists for referrals tds provides commercial service specially trained nurses take digital photos specialist software routes to consultant dermatologists (anywhere in UK) for diagnosis consultant can work from home tds replaces local consultant but not totally

Manchester tds sites North Manchester reduced waiting list from 18 months to 17 days in 6 weeks Medway dealt with backlog of 3000 patients in 15 weeks Expanding into Essex, Hertfordshire and Texas

Manchester Case study - WorldCare Consortium of 4 big American hospitals Provide "second opinion" service worldwide (20 countries) tele-radiology tele-pathology patient management consultation Local physician remains responsible

Manchester Case study - NHS Direct Biggest telemedicine project in the world Mainly telephone service Expanding to: web  online diagnosis for common conditions  health encyclopaedia  my NHS healthspace (personal info portal): news, reminders, knowledge digital TV
