How AI in Healthcare is performing diagnosis and saving lives at NHS

A doctor can use Optical Coherence Tomography (OCT) scanners to scan an eye and detect eye diseases. OCT scanners create around 65 million data points each time they are used – mapping each layer of the retina and that's lot of data for doctor to study. DeepMind's AI claims to recognise 50 common eye problems from the OCT data - which means a doctor does not have to spend time in analyzing the data. The results of AI have been promising in the trials considering the algorithms were correct 94.5 per cent of the time, which is equal to retina specialists doctors who were using extra notes along with the OCT scans.
                                       Deepmind & Google joined force in 2014 to accelerate AI research in healthcare and built medical assistant application for the National Health Scheme.. The significant AI work done by Deepmind in diagnosing eye diseases as effectively as the world’s top doctors, to in saving 30% of the energy used to keep data centers cool & to predict the complex 3D shapes of proteins is disruptive in field of Artificial General Intelligence (AGI).
The application called Streams is a mobile phone app that aims to provide timely diagnoses using AI so that right nurse or doctor get to the right patient in time and save the lilfe of patient who would have died otherwise. Each year, many thousands of patients in UK hospitals die from conditions like sepsis and acute kidney injury (AKI), because the warning signs aren't picked up and acted on in time

Streams mobile medical assistant for clinicians has been in use at the Royal Free London NHS Foundation Trust since early 2017. The app uses the existing national AKI algorithm to flag patient deterioration, supports the review of medical information at the bedside, and enables instant communication between clinical teams. Shortly after rolling out at the Royal Free, clinicians said that Streams was saving them up to two hours a day. We also heard about patients whose treatment was escalated thanks to the timely alert by the app. Statistics show that the app saved clinicians time, improved care and reduced the number of AKI cases being missed at the hospital.

The above figure shows how the automated process in the medical app saves time and connects doctor directly to the patient with serious condition.

There has been controversy around Google taking Over NHS data when DeepMind was taken over by Google in early 2017. DeepMind, which is now owned by Google used to operate the NHS app independently until 2017. DeepMind justified the decision explaining how Google would allow the app to scale in a way that would not be possible by itself.  Earlier in 2017 the Streams app attracted controversy after the UK’s data watchdog found that the NHS had illegally handed 1.6 million patient records to DeepMind as part of a trials. DeepMind subsequently made assurances that the medical data “will never be linked or associated with Google accounts, products or services”, and that all patient data will remain under the strict control of its NHS partners. As long as DeepMind does not share or link patient data with Google it will be major achievement for NHS in providing smarter health monitoring for AKI and many more diseases.

Arnold Schwarzenegger motivational speech - Do you have a vision ?

I came across this motivational speech by Arnold Schwarzenegger. It is so relevant to people as well as software. Unless you have a dream and a vision of where you want to go you may not meet your goal. Most of the time the vision is like a dream which sounds too good to be true, too difficult to realize but you have to realize that it is your dream. there is something in you that realizes that you have it in you to that wants that dream to become reality.



Long time back when I was in college I came across a book in my fathers library. I read this book by Dr. Robert Schuller titled 'Success is never ending, failure is never final' and in that book he gives real life examples of so many dreams that he realized with his power of positive thinking. When he started with a dream he did not know how to realize the dream, he did not have a plan and the dream looked impossible. After dreaming the same dream in sleep and when awake his mind could slowly start getting a vision of the possible ways to realize the dream. It was slow process, took few days and it is important to believe in yourself and not give up your dream. Those who are mentally strong continue to spend a reasonable time nurturing the dream. Dr Sculler says it is here that your motivation is tested, if you are not passionate about your dream you give up on the dream and all the successful people we know have this one quality that they did not give up on their dream and even after minor failures they reevaluated the dream , re-imbibed the faith in their dream and started again.
              The human mind has this fantastic capability of processing information even when you are not awake and there is tons of material , research papers and books written about this subject. Often you will realize that when you have a problem and can't find a solution after a few days you think of s great ideas to solve the problem. I am not a scientist and I have never done any research on the subject I am writing about but I am passionate about these theories and from personal experience I believe when you are honest about solving some problem the mind does some processing in its spare time and one fine day dumps the solution to you. You may have had this experience and wondered why didn't I think about it sooner but what you should realize it that you, your mind or your subconscious mind - whatever you may like to call it was aware of the problem, the mind was processing all the time and it was finally come out with a solution  and this is no coincidence. What I want to say is your dream, your vision, your plan, your mind, your subconscious mind are all connected and when you are motivated they work together to realize your plans.

So why is a software developer / software architect talking about Vision? Well because when you build a software you follow the same technique that you follow to plan your life.

• You want to solve a real life problem or a business problem
• You are able to visualize a software that will solve the problem - in your mind you see the solution
• You can convince people why and how the software is relevant and sell them the idea
• You know what are the risks and how you will mitigate the risks 
• You have a vision of how this software will be designed and what technologies will be used to build it 
• You then then create the roadmap for implementing the software
• You make a plan to implement the prototype 
• Once the prototype is successful you create a plan to build the software in stages
• You monitor the software development so that things go as per the plan

If you miss any of the steps you may end up with end product that is not perfect. Like #Arnold said at the beginning you should have a vision, hunger and belief. Vision is something that is built on your knowledge. After a year you acquire more knowledge and experience and you may realize that your vision needs some changes and it is perfectly ok. Your vision is outcome of careful deliberations and thoughts and it should not change everyday but Vision can always improve when you have new insights.
