The need and lack of healthcare information in India

This article was first published in my Times of India Blog Staying Wired.

In my previous post I had mentioned about the importance of Artificial Intelligence and Machine Learning in healthcare specially for countries like India where the population is large and availability of skilled medical professionals is scarce. But is the healthcare infrastructure of India in a state from where it can take this great leap forward.

The primary requirement to be met for being able to utilize the fruits of AI and ML, is the availability of data which can be fed into the systems to make them learn. As we humans learn by reading so do these machines. They can gobble up volume of medical data, sift through them, learn, and generate more meaningful output during diagnoses.

However, there must be context to the data. We cannot train an algorithm by feeding it medical data from Europe and expect them to yield meaningful results in a tropical country like India. With different environmental and weather conditions, there is difference in the nature of diseases and the agents which cause them.

However, the question is whether India is well equipped with the health data of its citizens which can be used for the purpose of training these models. The answer would be a resounding ‘no’. Apart from a few top tier public sector hospitals like AIIMS basic IT infrastructure is lacking in most places. In private sector though some of the big names have provisions for Electronic Medical Records (EMR) the same cannot be said for other small nursing homes and hospitals operating throughout the country.

From personal experience even in a leading private hospital in Kolkata I never got to access EMRs online. They seemed to have an online portal, but no one in the hospital knew how, from whom and where to get access.

Moreover, an EMR in most cases doesn’t translate in to a meaningful Electronic Health Record (EHR). In retail a well-used term is the ‘One Customer View’ through which a retailer knows his customer holistically; what he buys, which brand he likes, how much he spends, what are his/her dislikes and most of the other relevant preferences.

EHR should be able to provide healthcare agencies similar holistic view of a patient’s entire health history, so that in time of need or emergency there is no scrambling around looking for allergies etc. Transparent sharing of EHR across hospitals would also make it easier for patients to continue the correct course of treatment while shifting from one city to another.

Worldwide the adoption of EHR has been rapidly progressing. In most of the developed European nations the adoption rate is more than 90%. In USA as of 2014, 76% of hospitals and 97% of acute care hospitals had adopted for EHR. For India no certified figures could be found, some resources point the adoption to be in the region of 20-30% only.

Despite some recent advances with public healthcare spending in India below 1.5% of GDP not much change can be expected to take place. Globally most countries have understood the important part IT is to play in the healthcare domain. By 2020, the global healthcare expenditure is expected to reach $9 trillion out of which $1.7 trillion will be in technology; almost reaching one-fifth of the total.

It is quite a contradiction that India being home to some of most prominent names in information technology industry, is lagging poorly in revamping its own healthcare. There are multiple healthcare schemes launched by successive governments but all this while the allocation for health never reached 2% of the GDP. Even considering the emerging countries of the BRICS group, India stands out at the bottom when it comes per capita healthcare expenditure; just $75 for India as against $947 for Brazil at the top.

None of the fruits of new age technologies could be availed till this apathy towards healthcare is corrected to the core. Having a comprehensive EHR for all citizens would be a goldmine which is to be protected with an equivalent zeal. The data so far available is scant, scattered and localized.

About 72% of the rural and 79% of the urban residents today avail private sector services for healthcare. But over reliance on private sector would make it hard to realize the requirements of an integrated EHR framework. Government needs step in with the initial necessary capital investment, policy formulation and provide the necessary governance framework; since it is necessary that the information is not put to rogue use. Once the integration is achieved the benefits would just be exponential.

Artificial Intelligence and the future of healthcare

This article was first published in my Times of India Blog Staying Wired.

Anyone reading this post would know how predominant has been the terms ‘Artificial Intelligence’ and ‘Machine Learning’ in this millennium. Though these fields have been under the research radar of scientists from a much earlier period, it is only in the last few decades that AI and ML have matured out of the test-tubes to face real-world challenges. And healthcare is one field which stands to gain from that.

It would not be too far-fetched to predict that the advances in medical science like vaccination and genetics which helped to further human longevity, Artificial Intelligence would bring about the next quantum leap. And as we discuss multiple instances of applications of AI and ML have already started coming to the forefront.

In the detection of cancer, metastasis pathologists are faced with the time-consuming task of reviewing slides of high-resolution images covering every tissue under investigation. The images are in the magnitude of 10 gigapixels and a pathologist must go through each pixel to ensure that he isn’t missing anything important.

AI algorithms reading the visual patterns are expected to be between 5-10% more accurate than pathologists with unlimited time studying the same images. And since being machines they are expected to be more consistent as well. This increased accuracy and consistency can strongly fight off misdiagnoses.

In another brilliant example, Madurai based Arvind Eye Hospital has started testing a Google AI based interface which can provide early against diabetic retinopathy, which if untreated can lead to permanent blindness. However, with just 11 ophthalmologists for 10 lakh people, not everyone is expected to undergo regular eye checkups in India. Such AI interfaces, providing preliminary examination results fast and at low cost, can go a long way to bridge the gap w.r.t availability and reach of doctors.

AI systems have found extensive usage in diagnoses of common ailments along with predicting how long a patient would stay in hospital or chances of readmission and even death.

In China studies conducted on a wide base of patients have shown amazing results. AI systems diagnosed asthma with 90% accuracy as against physicians whose accuracy ranged from 80% to 94%. For gastrointestinal diseases, AI systems were 87% accurate while physicians were in the 82-90% bracket. Thus AI systems can be overwhelmingly reliable in terms of generating a consistently accurate outcome. And hopefully, with further proliferation, it will be cheap and maybe even open source sometime in future.

But that doesn’t mean there are no pitfalls. Anyone with access can fudge the medical records to fool AI systems. And many scientists have already proved so my performing tricks with AI systems which made these machines fall flat. So it can be well said that the introduction of AI will no way reduce the importance of the work a physician or a pathologist does. It only shifts the nature of work.

Pathologists and doctors can let AI systems perform the preliminary investigation while they get look at exceptions and outliers. For the patients, especially in countries like India where competent doctors are scarce to be found, AI systems could be the first line of the interface at primary healthcare facilities where preliminary diagnoses can take place.

We should be aiming at an augmented Healthcare system where physicians and AI can work hand in hand providing the best possible outcome for the patient. With the growing population and ever new complications in diseases arising, the field where humanity needs to embrace the combined might of Machine Learning and Artificial Intelligence most are not self-driving cars or productivity enhancing robots but healthcare.

Towards a smart future #SmartHomeRevolution #GetFitWithFlipkart

  • You have left your house for a long drive and have been on the road for few hours. Then suddenly the thought strikes you whether you had switched off all the electrical devices before leaving.
  • You are out on vacation but was expecting an important package to arrive by mail. You wish if you could have spoken to the delivery guy and let him know where to put it lest it gets spoiled.
  • It's a hot and humid summer evening when you are on your way to home. If someone could have switch on the AC few minutes before you reach home, it would have been really nice.
These are all quite familiar cravings we have and would be part of many of our wish lists. The answer to these above requirements could be a smart light, a smart camera or in entirety a smart home.'

India today has the second highest smartphone using population in the world even ahead of the USA. However considering a penetration of less than 30%, it means there is still ample scope to increase the smartphone usage in the country.

Today smartphones are an integral part of our life. We remain connected with family and friends, pay our bills, keep track of finances, update social media and even do work through smart phones. The smartphone that we have in our hands today comes with immense computing power. It is said that the computing power we have in a high-end smartphone today would have been enough to blast off a rocket into outer space in the 1950s.
However the gap that not been bridged yet is that between the phone in our pocket and the other devices we use in daily life; our car, our watch or the electrical and electronic appliances in our house. It is to bridge this gap that smart devices have come into picture.

Smart wearables were the first smart devices that became of popular use. Today we can see enough people wearing a Fitbit or Apple Watch or Samsung Gear or any other smart watch to consider. With these wearables we can not only do things which we would have otherwise done using a smartphone like receive calls, text messages, check emails, listen to songs but these devices also act as a personal health monitor by keeping a tap on some vital body parameters like heart rate, pulse and also track calorie erosion when we engage in physical exercise.

The wearables help us to set personal health goals and help keep a track how far we progress on that; it helps us to live a bit more healthier life. Google Glass has opened a new frontier in the wearable technology field with widespread application starting from medicine to journalism. In India Google Glass should find application in the education field as well; when many of  the children are deprived of quality education, enabling live streaming using Google Glass has help students in far flung areas to have more accessibility to quality material

The Global Wearable Devices Market is expected to exceed more than US$ 51.50 Billion by 2022. Wearable devices are here to stay and penetrate our daily lives. In India the wearable device market is set to reach to a stage very close to $2 billion by 2023 while the penetration is not expected to change much from current levels.
Hopefully that will change soon as more Indians become health conscious and application of wearable is expanded beyond just the millennials. Wearable technology should be able to find wide scale used case among the elderly population where the devices can be used to trigger emergency response.


And when we talk of daily life, nothing is complete without an interaction with our home and it's appliances be it the oven, the air conditioner, lights or the security system. We now have smart thermostats which can be controlled remotely through apps in smartphones; thus we can now switch on the AC or heating before reaching home to have a more comfortable experience. Smart thermostats can also alert the owner in case of any abnormal changes like fire. We now have smart lighting solutions which can be controlled through apps.

Thus while on vacation you can still switch on and off the porch lights remotely or may be control the Diwali decoration lights. Smart cameras can help you keep an eye on your house remotely. There are also voice integrated smart security camera which can help the owner interact with any unknown person knocking at the front door or may be instruct the delivery guys to keep the parcels in the right place. And to integrate all these smart devices we can have a Google Home or Alexa; from playing the favorite song to opening the garage door these smart device integrators can do any task you just ask them to do. And that means no need to even use a smartphone app; you just say and Alexa does it.

Apart from convenience, smart devices add to the better management of energy by controlling the devices effectively as per need. Artificial Intelligence integrated with smart devices increases their utility many times more. Thus while we may witness a marginal increase in the initial installation cost, the effective savings on running cost over a longer time would weigh out the initial investment many times over.

In the US alone, smart home is expected to be a $40 billion plus business with a penetration into more than 50% households by 2023. Compared to that in India the penetration is expected to be less than 10% by 2023 generating a business of $7 billion. Thus India provides a far larger market in terms of opportunity.


One of my first interactions recently has been with smartness built in today's car. I had recently the experience of using a Bluelink enabled Hyundai Sonata. With this new technology you can now start you car remotely with the a smart phone app, lock or unlock the car, control the cooling and also technology will help send alerts and updates from the car. This is something very basic considering the world has moved into the realm of self-driving cars. However such smart connectivity is yet to come in cars which fall outside the premium segment in Indian. Hopefully in very near future that will no longer be the case. Connected car market and ecosystem is evolving across the globe. By 2023, connected car and related accessories will be a billion dollar market in India alone.


Smart devices are expected to have widespread use in the public space as well. Smart lights can help municipal bodies to more effectively control the city lighting and manage any wastage. Today's cities consumer more than 70% of the world energy production, thus effective management of resources can definitely help in the long run to create a sustainable ecosystem.
Chicago has undertaken an ambitious and largest (in USA) project to replace 270,000 city lights with smart lights resulting in an estimated savings of $10 million is energy costs annually.

Smart cameras can be used to monitor security and more effectively manage traffic in busy urban freeways. And the data from all these connected devices provides the as big an opportunity for analytics and machine learning to work more effectively. In Nairobi, Kenya Huawei has installation communication system that integrates 1800 smart cameras with 195 police bureaus and 7600 police officers providing a sense of national and economic security. India has also embarked on an ambitious journey of building 100 smart cities with an estimated funding of $14 billion. In India such smart solutions can also help to address to the problems related to women's safety.

That day is not far when on a long road trip while driving you can feed an instruction to the Alexa or Google integrated car to switch off the lights in you drawing room and the task will be done. And when you reach back home exhausted your car will communicate with the garage security system to open the gates and also ensure the hot water is ready for you to take a refreshing bath.
And the local police station become aware of a theft or burglary even before the owners actually dial the emergency response number.

The applications and opportunities are just endless. So get your first smart device from Flipkart which provides an amazing collection of Smart Wearable, Smart Home, Smart Camera and Smart Light solutions to choose from.

What is written on your license plate? Do you know why?


Top post on IndiBlogger, the biggest community of Indian Bloggers
When I first time had a car in the United States in the state of New Jersey, the license plate had a legend which said 'Garden State'. I assumed that it could be a reference to the gardens and parks which the state has but, as I now know, my assumption was naive and incorrect. Then when I moved to Texas, the legend on the license plate changed to 'The Lone Star State'. However I didn't think much about it and it didn't arouse much curiosity in me.

But recently when I was travelling to North Carolina the tag on the license plates had me thinking. It mentioned 'First in Flight'. Now this had me thinking. Why was it that every state had a different legend on the license plate and what each of them meant? As usual did some online research and below are the results.

The story of Insulin - the first genetically engineered therapeutic agent


Top post on IndiBlogger, the biggest community of Indian Bloggers

Featured post on IndiBlogger, the biggest community of Indian Bloggers
The importance of insulin cannot be overstated to any person who is himself a diabetes patient or has a family member suffering from that. And it's lifesaving value cannot be attributed to the price tag. India is often called the diabetes capital of the world with about 9% of its population suffering from the ailment. India has more than 70 million adult diabetes patients and some studies indicate diabetes reaching the scale of a potential epidemic in India.

Diabetes results when our pancreas don't produce the insulin hormone (Type 1 Diabetes) or if the produced hormone doesn't function in the expected manner (Type 2 Diabetes). To counter these situations today we have externally synthesized insulin shots which can be taken to supplement body's need for the hormone. However this was not achieved over night.

How was life of a diabetic patient before insulin was discovered? Considering the fact that even in 2015 we had 1.6 million deaths directly attributed to diabetes, it can easily be understood the importance of insulin. Before the discovery of insulin shots, the only known way to treat diabetic patients was to put them on a low calorie diet. However, that often led to death by starvation. Children diagnosed with diabetes rarely lived; more than 80% died within 10 years of first detection. Having Type 1 Diabetes was effectively a death sentence.

The discovery of bio-synthetic insulin currently in use is a process which took more than 100 years to achieve its ultimate objective. It contains years of hard work and toil from hundreds of researchers working across the world. As many as 4 Nobel prizes were awarded for work directly related to discovery of insulin and many more with indirect association.

How far unbiased are the competitive examinations in India?

When it comes to education few countries in the world are as close to India in terms of competition; well on second thoughts China would be one. Considering the population of either of these countries it's not surprising that competition to get entry into one of the top institutions would be so cut throat. After all the students know getting entry into a good college is the assured way to secure a good future for themselves and their families. Thousands of students appear for entrance examinations every year at the culmination of a journey which involves a lot of sacrifices in both monetary and emotional terms.

Thus it is important that tests organized for admission to these institutes are unbiased to the maximum extent possible; any bias could provide an undue advantage to one group of students over the other. In India there are a number of entrance examinations conducted some at an all India level and some at State levels. And for each of them we have quite often heard how one section of students is at disadvantage over the other. For example, it is widely known that students pursuing plus 2 in CBSE board are more at advantage (because of the syllabus content and coverage) than the students pursuing a State board for plus 2 study. And hence to counter this the State level competitive examinations are tuned to the State board syllabus.

Book Review | Numbers Rule Your World - Kaiser Fung

Numbers present a fascinating view of the world. In every day working we knowingly or unknowingly engage with numbers and probability in different forms. When we open our daily newspaper in the morning we are bombarded with a deluge of numbers which are scattered across all the pages; cricket scores, match statistics, player analysis, stock market performance, social and human development indicators just to name.

Numbers, their statistical analysis and visual representation is a wide field of study with application in almost every field of study. The title of this 'Numbers Rule Your World' is more than appropriate. This is a wonderful read on how number and statistics are prevalent in the world we live.
A book on statistics generally tends to be boring for a layman if it is more academic oriented and involves usage of a lot of technical jargon. However this book is not one of that type. In this book the author establishes relationship between statistical concepts and how they have come to influence events in modern times.

The book is segregated into 5 chapters each dealing with one fundamental concept from the world of statistics followed by a concluding section and a most important section on 'notes'.

Indians with Nobel in Mathematics | Part 1 - Abel Prize

It is often asked, answered and debated why Alfred Nobel didn't include Mathematics as one of the subjects along with Physics, Chemistry and Physiology or Medicine when he first instituted the first five Nobel Prizes; Literature and Peace being the other two.

There are multiple explanations for the exclusion of Mathematics. Some say Mathematics was not considered as a fundamental science which could directly human well being. Some say that there were plans of a prize being instituted by the King of Norway and Sweden, who himself was also a mathematician, for excellence in Mathematics. While some other points out to personal angle wherein it is said that the woman he proposed to rejected his proposal in favor of a Swedish mathematician of the period, Gösta Mittag-Leffler, and hence he despised of mathematicians and mathematics.

Reading the Menu

How often do you go through the menu card at a restaurant with great detail? If the restaurant is one of your regular ones, then you mostly know what to order. However, if it is a new one where you want to try our do you really read through the entire menu? How do you selectively move through the menu and arrive at your choice?

Definitely there are certain patterns to that and it is that a carefully designed menu card would exploit. The below images are taken from an article published in the Readers Digest magazine. While going through the article I really appreciated the fact how much it is relevant and how many times my choice is guided by the menu card's design and not by the exact know-how of the food.

Some of the often used tricks are items priced like 9.95 / 9.99, items marked in box or marked as 'chef's choice'.

One other point which I frequently observe in the menu card, but not listed in this article, is the calorific value of the food. Consider how health conscious our generation has turned out to be, mentioning the calorific value do drives people choices.
