     • in patient records, medical equipments, internet
       devices…etc
   Advantages and disadvantages of using ICT in
    medicine
   Computers and the disabled
   Examples of computer systems used by the disabled
The uses of ICT in medicine
    Patient records
   Medical records used to be stored on
    paper but now it is transferred to a
    computer data base
   It keeps a track of patients’ medical
    history e.g. the prescribed drugs and
    what illness the patient has suffered
    from
   Data bases of patients have been used to
    track trends in illnesses such as heart
    disease
   Data bases of organ donors and patients needing
    transplant
                  Patient records 


                           Advantages




                                                           Transfer of records
Access will                         Writing will be easy     will be quicker
              Takes up less space
be quicker.                               to read                between

    Take much time
                     Medical equipments

   Scanners
    • Are used to process their data into a
      readable format


   Microprocessors
    • Are used to control a variety of medical
      devices such as pacemakers


   Computer guided lasers
    • Are used in operations. For example the
      removal of brain tumors

can break down                new equipments
                               Research
   ICT has changed the way in which medical research is conducted

    • Modelling the effects of new drugs

    • ICT is used to conduct clinical trials

    • Collaboration between international teams e.g. Human Genome Project
                         Research



                         Advantages




                                          Collaboration

     Can never
replace clinical trials
    Web-based diagnosis (Internet services)

   You can find a wide variety of medical
    information such as :
    • Symptom diagnosis, for people who wish to identify
      their problem without consulting a GP (General
      practitioner)
    • Access to medical research/journals
    • Information about side effects
    • Information about available treatments

      Expert systems

   Also called knowledge-based systems
   They are computer programs that attempt
    to replicate the performance of a human
    expert on some specialized reasoning
    tasks
   Store and manipulate knowledge so that
    they can help the user to solve a problem
    or make a decision
   Expert systems are being used for disease
    diagnosis
         Example of expert systems

   Robots
    • They have been used to perform
      very accurate operation such as
      those on the brain
                           Expert systems



                               Advantages

  Expert systems



  Disadvantages



    Some people
prefer a human touch
Communications

   Teleconferencing has been used to share
    expertise
    • Surgeons in one country can help those in the
      other
   Wireless transmission provides a link
    between hospitals and doctors
   Telecommunications
    • Remote diagnosis can be used to diagnose
      and treat patients remotely
    • Patients can monitor their own conditions at
      home without need for a visit in a hospital
            Computers and the disabled

   About 10% of people in Britain has some kind of disability
   Computer systems :
    • Improve the ability to communicate
    • Provide opportunities for independence and employment
   Examples:
    • Scanners to convert printed text to verbal out put for visually impaired
    • Voice recognition equipment to convert speech to printed output for
      hearing impaired
    • Special pointing devices to allow interaction with computer for
      physically impaired
    • Vision systems with sensors built into special glasses
    • Computerized devices implanted to improve mobility for physically
      impaired
                          Examples

   Scanners to convert printed text to verbal out put for visually
    impaired
   Voice recognition equipment to convert speech to printed
    output for hearing impaired
   Special pointing devices to allow interaction with computer for
    physically impaired
