Introduction
ICT is used in many ways in the provision and management of healthcare services: Hospital administration Medical training Maintenance of patient records Communications between
doctors/patients/hospitals Diagnosis Monitoring Surgeries

Objectives
You should have an understanding of a wide range of work-related ICT applications and their effects, including applications in medicine doctors’ information systems hospital and pharmacy records Monitoring expert systems for diagnosis

We will look at the processes in a logical order, considering the advantages and disadvantages of using ICT in each one.

Patient records
Patient records used to be written on paper, and stored in huge, manual databases.
This made accessing the records slow. Sometimes records could get lost, and there was no easy way to make a back-up copy, or to search for specific groups of patients

Patient records
When a patient registers at a surgery, details are recorded on a database
Computerized databases mean that patient data can be easily shared between doctors, pharmacies and other hospitals
It is easy to search for and retrieve patient records

What data is held?
In the case of hospitals, the patient data that would be typically stored would be:Patient ID (number or text) - this would be the key field
Name (text) Date-of-birth (date) Gender (boolean) Next of kin (text) Blood group (text) Allergies (text) Medical history (text) Doctor currently treating (text) Current symptoms (text) Current diagnosis (text) Current treatment (text) Current medication (text) X-rays or body scans (links to image/video files)

Other appointments
Doctors can access a patient’s records whilst they are visiting patients, by using a computer connected wirelessly to the hospital network.
Advantages?Possible problems?

Doctors often use tablet computers (which are portable like laptops, but have a touch screen, and no keyboard) as they can be held in one hand, and operated with the other.
Notes can be written on the screen using a stylus, and handwriting-recognition software converts it into computer text data.

Advantages
Ease & speed of access to relevant patient information
No need to carry notes around (bulky, heavy, problems in case they are lost)
Access to communications if need for urgent referral to hospital etc
Also access to online diagnostic tools/reference material

Diagnosis
Embedded computer systems Electronic diagnostic equipment eg
body scannersCT scanners and MRI scanners
allow doctors to investigate what is happening inside a patient's body without intrusive surgery.
