introduction
Introduction
  • ICT has had a major impact in all aspects of health care and medicine in the past 20 years.
  • Main Uses
      • Administration inc. Patient records
      • Diagnosis
      • Monitoring and Treatment
      • Telemedicine
      • Health Economics
admin patient records
Admin & Patient records

GP Level

  • Most now use limited IT based system
  • Carries only basic information
  • Treatment records tend to be still paper based - paper file of records
  • Fund holding has lead to need for more efficient and accountable systems
admin patient records4
Admin & Patient records

GP Level(cont.)

  • Paper based system very inefficient
  • records get lost, become indecipherable
  • difficult to analyse - trends, demographics, costs etc.
  • transfer of records slow - GP to GP; GP to Hospital
admin patient records5
Admin & Patient records

GP Level(cont.)

  • Many systems not compatible with each other
    • Need for standards
  • High cost of transferring legacy records
  • High cost of training staff
    • Need for funding
admin patient records6
Admin & Patient records

Hospitals etc

  • No overall strategy
  • Some small scale move to digital records
  • Most treatment records still paper based
    • very inefficient and costly
  • Large areas needed to simply store records, x-rays etc.

Admin & Patient records

The (possible) future

  • Central patient record system for all UK
  • Accessed by all : GP - hospital
  • All information digitally delivered and stored - inc scans, x-rays etc.
  • Possible use of smart card for recent records
diagnosis
Diagnosis
  • Major Use -scanning
    • CAT - Computer Aid Tomography
    • MIR - Magnetic Image Resonance
    • PET - Proton Emission Tomography
    • Enhanced X-ray
    • Enhanced Ultra sound
  • All use sophisticated computer techniques to visualise deep body systems
diagnosis9
Diagnosis

Expert Systems

  • Some , mainly USA, moves towards computer aided diagnosis.
  • Computer asks series of questions which leads to possible diagnosis.
  • System limited at present - can miss serious illness
monitoring and treatment
Monitoring and Treatment
  • Computer aided systems widely used for patient monitoring - heart rate, blood pressure, temperature etc.
  • Mainly intensive care but moving into general ward use
    • provide regular updates, can perform some analysis/early warning
    • frees up nurses/doctors for other duties
monitoring and treatment11
Monitoring and Treatment
  • Increasing use in treatment systems
  • Radiological/laser systems -dose delivery, positioning
  • IV drug pumps
  • Automatic monitoring of chemical levels levels e.g. insulin, with remedial delivery of drugs
telemedicine
Telemedicine
  • Use of computer/communications technology to deliver:-
    • remote diagnosis
    • remote monitoring
    • health education
  • Increasing use in rural areas (UK)
  • Widely used in third world and other remote areas
health economics
Health Economics
  • Controversial area
  • Uses computer technology to calculate costs of treatments
  • Can be (and is) used to decide if economically viable to treat patients
    • particularly elderly and terminally ill
other uses
Other Uses
  • Bar code tagging of patients
  • Bar coding of blood packs
  • Digital hearing aid technology
  • Muscular stimulation in paralysed patients
  • Bionics - computer aided artificial limbs etc.
other uses15
Other Uses
  • Trend and pattern spotting - epidiomology
  • Drug design
  • Genetic Engineering
  • DNA analysis
  • 3D imaging in reconstructive surgery
  • Internet diagnosis
    • worrying trend, many charlatans and fraudsters
the future
The Future
  • Increased use of computers in all aspects of health care
    • faster
    • more efficient (in some cases)
    • may help to fill skills gaps

but

    • impersonal
    • can go wrong
