  1. Technology in Medicine The Use of Computers Mr. Howerton Fall 2012

  2. How are computers used in medicine?

  3. Medical informatics The storage, analysis, and communication of information I medicine Communication Internet Medical records Diagnostic Support Pharmaceutical Prescriptions Health System Modeling Data Mining

  4. Administrative Applications • Patient records • Billing • Filing Insurance claims • Imaging Data • Transcribing reports • Scheduling appointments

  5. Clinical and Special • Patient data • Pharmaceutical referencing • Medical guidelines • Calculations • Scheduling and appointments • Databases of pharmacy numbers, consultants, etc • Contact among other medical professionals

  6. Computer-Assisted surgery • Use computers, cameras, and robotic arms to examine and perform surgically- non-invasive procedures on a patient. • Knee repair • Gall bladder removal • Unblocking arteries

  7. Prosthetics • Designing • Fitting • Control of prosthetics • Monitoring use of prosthetics

  8. Pharmacy • Client records • Inventory • Insurance • Guidelines • Pharmaceutical references • Billing • Contacts

  9. How is digital imaging used in the radiology these days?

  10. Digital Imaging • No developing process – quicker • Copies as good as original • Viewed on computer screen • Can be transmitted over phone lines • Less radiation • More flexible • Can be highlighted or enhanced

  11. Traditional X-Rays • Traditional X-rays use electromagnetic waves to make pictures. The high-energy waves travel through soft tissue but not through the dense materials of bone. It can be used to detect pathology of the skeletal system as well as some soft tissue • Used in orthopedics and dentistry • video

  12. Digital X-Rays • Computers make pictures using mathematical information • Appear instantly on the computer screen • Can be emailed to others for help in diagnosis • Can be manipulated by the computer to create better images • Allows greater access to radiology in remote areas

  13. Mammography • a low-dose x-ray system for the examination of breasts. • A mammogram is used as a screening tool to detect early breast cancer in women • plays a central part in early detection of breast cancers • show changes in the breast up to two years before a patient or physician can feel them.

  14. Ultrasound • Also called sonography, • uses of reflected high-frequency sound waves to create image • Captured in real-time • Examine movement of object • Video

  15. Computerized Tomography (CT) • CAT scan • uses special x-ray equipment to obtain image data from different angles around the body • computer processing of the information shows a cross-section of body tissues and organs. • Video

  16. Magnetic Resonance Imaging (MRI) • uses radiofrequency waves and a strong magnetic field to create images • Has a broad use for diagnosis • video

  17. Positron-Emission Tomography (PET) • PET Scan • radioactive material is injected into body • radiation from the emission of positrons • Used to view cancer and blood flow • Uses to study Alzheimer’s and Parkinson’s • Video

  18. Interventional Radiography • use previously mentioned technology to insert catheters to treat disease (through the skin). • Advantages: outpatient, less cost, less pain, local anesthesia

  19. Stereotactic Radiosurgery • delivery of a single high dose of radiation in a one-day session to a tumor • Mainly for brain tumors • video

  20. Focused UltraSound Imaging • ultrasound beams are focused on a tissue • temperature within the tissue rises to more than 65°C, completely destroying it.

  21. What is Telemedicine?

  22. Telemedicine • Definition: “The use of computers, the Internet, and other communication technologies to provide medical care to patients at a distance.” • Includes: • Diagnoses • Patient monitoring • Treatments

  23. Telemedicine • Telehealth: • Larger field that includes health-related education • public health research • health services administration

  24. Telemedicine • Advantages: • Brings high quality medical care to anyone regardless of distance • Decreases patient wait time • Decreases patient travel time

  25. Telemedicine • Teleradiology: Oldest form of telemedicine using computers and telecommunications . • Interactive video conferencing: Conferencing that allows medical professionals and patients to consult in real-time, using telephones and video screens.

  26. Telemedicine • Telepathology: Transmission of microscopic images over telecommunications lines allowing the pathologist to view images on a monitor instead of under a microscope. • Telepsychiatry: Uses teleconferencing to deliver psychotherapy. May not be suitable for some types of mental illness.

  27. Telemedicine • Remote monitoring devices • Telespironmetry- • used for asthma patients • information transmitted over telephone lines to remote location • Arrhythmia monitoring • ECG telemetry that monitors a patient’s cardiac status and sends it to a remote location

  28. Effectiveness of Telemedicine • Examining a patient at a distance is not the same as examining that patient face to face • In prisons, telemedicine has led to decreased costs and improved health care for inmates

  29. Effectiveness of Telemedicine • Medical assistants at the remote sites may be useful • Small hospitals and clinics may find hardware costs prohibitive • Research studies generally favorable for medical and cost effectiveness

  30. Use of Telemedicine • Health care to the elderly (homebound) • Connect rural primary care physicians to urban specialists • Allow families of high-risk newborns to watch babies’ hospital care from home • Data can be transmitted from ambulance to ER • Patients with chronic illnesses can receive medication reminders at home

  31. Issues with Telemedicine • Technical issues • appropriate telecommunications infrastructure must be in place • not available in some rural and urban areas • requires high bandwidth (cable modem)

  32. Issues with Telemedicine • Insurance issues • insurance may not coverall telemedicine • Legal issues • licensing laws differ in each state • liability is not clear • Privacy issues • electronic medical record subject to misuse • HIPPA (Health Insurance Portability and Accountability Act of 1996)
