In many, many ways. Here's some things you can talk about:
•Previously we stored patient data by hand on paper. Now we use computers to store it. This is better because what if we accidentally lost/destroyed the papers or it burned down? With computers this risk is minimised.
•We can now diagnose patients with problems with much more precision thanks to advances like MRI scanning, CT scans, and X-rays. This means we can pinpoint problems rather than guess what’s wrong.
•Prescriptions for medicine can now be arranged online and delivered to your door in some areas, whereas previously you would have to walk in and get the medicine which could be time consuming.
•We now have phones to dial 911 for emergency ambulance services. This has revolutionised how quickly responders can respond to life threatening events.
There’s much more to talk about, but all of the points above are a sold start.
