| Define Expert System | A computer system that emulates decision making ability of a human expert. Uses artificial intelligence to make decision based on data supplied in form of questions/answers. |
| Name and define the three parts of an expert system | 1. Knowledge base- physically stored data 2. Inference Engine- set of rules for making the deduction 3. User interface- user software that asks questions/displays answers |
| Advantages of Expert Systems | Available 24/7 Can help train young doctors in unfamiliar diseases Computer can store far more information than a doctor Computer does not forget/make mistakes Will never retire so no loss of expertise Data can be kept up-to-date more cheaply than training doctors Provides second opinion with probabilities |
| Disadvantages of Expert Systems | Dependent on correct information being put in GIGO Dependent on correct rules being programmed in No common sense Some experts could lose their jobs |
| Describe Blood Bar Code System | Allows tracking of blood from its donation to its use. Patients have bracelet with bar codes that's matched with barcode on bloodbag |
| Advantages of Blood Bar Code System | Blood tracked from donor to patient- cut down cross contamination Ensure correct blood given to correct patient - reduce mistakes Better stock control of blood |
| Define EPR (Electronic Patient Record) | All patients given barcoded bracelet with their patient number name/details of doctor. Bracelet scanned and used to look up records/treatment details. |
| Advantages of EPR | Records can be kept up to date instantly reducing mistakes Complete information can be called up by doctor from anywhere with computer terminal in hospital Less chance of wrong medicine being given Less chance of wrong side being operated on GPs can link into system see how patients are doing |
| Give 5 uses of sensors | Temperature Pulse Blood Pressure Fluid level testing Heart rate |
| Advantages for patient care using sensors | Continual monitoring of patients 24/7 Alarms set for extreme readings- react immediately Accurate reading/recording- spot trends New born babies and wristbands- prevent being taken from ward |
| Problems with sensors | Calibration need to check accuracy Cost of purchase |
| Describe MRI scanners | Lots of detail on tissue of info- good for detecting brain tumours Use magnetic radio waves to build up picture- large cylindrical magnet. Very clear pictures produced and examine heart/blood vessels. |
| Describe MRI scanners | Lots of detail on tissue of info- good for detecting brain tumours Use magnetic radio waves to build up picture- large cylindrical magnet. Very clear pictures produced and examine heart/blood vessels. |
| Describe CAT scanners | Produces complete 3D model of a patients bone and internal organs Assembles picture based on strength of signal |
| Advantages of CAT scanners | Produces accurate diagnosis without need for surgery Removes danger of post-operative infections Leads to faster recovery |
| Disadvantages of CAT/MRI scanners | Expensive to purchase/run Need for expert training Could result in loss of traditional diagnostic skills Claustrophobic/stressful in MRI Pacemakers/metallic limbs can't go through scanners Increased risk of cancer - prolonged X-ray exposure |
