We are at a crucial point in our history today \u2013 harnessing the potential of data to fuel technological innovation [i]<\/a>. While the theory behind advanced data-sciences is decades old, we are now no longer limited by technology and data collection hurdles and can use more efficient processes to analyse data. ML has started gaining traction in traditional industries- from helping predict the next maintenance requirement at a power plant all the way to detecting and preventing financial fraud in real-time[ii]<\/a>. It has helped entire industries evolve their operations to make them more proactive, rather than reactive, and made organizations much more efficient.<\/p>\n

<\/a><\/p>\n

Elementary Iterative Process Flow Diagram<\/figcaption><\/figure>\n

In industries where the first step above has never been a hurdle (think production facilities or financial institutions), ML has unlocked potential\u00a0 faster. In traditional industries like healthcare, where data collation has been a challenge \u2013 both in terms of quality and quantity \u2013 availability is only starting to improve through the increasing use of Electronic Medical Records (EMRs) and Electronic Health Records (EHRs). ML in healthcare has also limited itself to more analytical and pattern-recognition applications[iii]<\/a>. The most commonly cited examples are those of computers being trained on a large number of images\/scans to identify cancerous tumours or abnormalities[iv]<\/a>, [v]<\/a> and to aid in the drug discovery process[vi]<\/a>.<\/p>\n

<\/a>Healthcare and ML<\/u><\/strong><\/p>\n

ML\u2019s true potential as a technique has always been the ability to draw insights \u2013 analyzing sets of data to give users a more diagnostic picture, which can then be furthered to share a degree of predictive recommendations (a.k.a \u2013 treatment!).<\/p>\n

Sounds familiar? Because what I have just described is the standard medical process and patient journey of analysis, followed by diagnosis and treatment recommendations. In this scenario, the doctor is training herself through her experience. These patients are shaping her \u2018learning\u2019 and helping her build an intuition of sorts that gets applied then to all subsequent cases that she comes across. It isn\u2019t without reason that her work is referred to as a medical \u2018practice\u2019.<\/p>\n

\u201cIt\u2019s been said before that the best ML tool in healthcare is the doctor\u2019s brain.\u201d[iii]<\/a><\/p>\n

It is this equivalency with modern day ML that brings us to the core issue surrounding the applications of ML in healthcare. How can ML be harnessed to augment the skills of a medical practitioner, instead of threatening to replace that stakeholder completely?<\/p>\n

Curai and Natural Language Processing (NLP)<\/u><\/strong><\/p>\n

One of the ways to approach the question above is to look at what the limitations of a traditional medical practitioner are, and can ML be used to solve them. A couple of such challenges are:<\/p>\n

    \n
  1. The availability of diverse patient populations to train doctors on<\/li>\n
  2. Keeping oneself updated with all recent advances in one\u2019s area of medical practice<\/li>\n<\/ol>\n

    Curai is a start-up that uses ML in the form of Natural Language Processing to train itself on delivering relevant primary care information to both patients and doctors, enabling a more efficient conversation between these stakeholders [vii]<\/a>. At its core, Curai, through partnerships with reputed medical institutes and other knowledge partners, collates patient-doctor conversation data and matches it with medical histories (through EMRs and EHRs) to build a working knowledge of primary care diagnostics[viii]<\/a>. This is used to help patients entering the healthcare universe with an understanding of their symptoms\/conditions that is accurate and based in sound medical knowledge.<\/p>\n

    <\/a><\/p>\n

    \"\"<\/a>
    Curai Sample Process Flow[vi]<\/a><\/figcaption><\/figure>Some of the applications of this technology are listed below:<\/p>\n
      \n
    1. Improving primary-care access<\/strong> \u2013 Through sufficient training, the AI will be able to provide sound medical advice for people across the globe with limited access to doctors[ix]<\/a><\/li>\n
    2. Medically relevant response\/question suggestion<\/strong> \u2013 Using the information available from a patient and matching it with possible outcomes, Curai could guide the probing questions from a doctor to arrive at a core diagnosis much faster<\/li>\n
    3. Improve patient compliance<\/strong> \u2013 with the ability to refer to Curai, patients will find it easier to understand and comply with recommended treatment protocols<\/li>\n<\/ol>\n

      A key issue for Curai will be to stay at the forefront of medical knowledge and continue to learn and extract relevant meaning from a patient\u2019s inputs. It will also be crucial to position it as an enabler for medical practitioners that improves access and builds better relationships between doctors and patients.<\/p>\n

      \"\"<\/a>
      Avoid this at all costs.<\/figcaption><\/figure>\n

      Questions for Curai<\/u><\/strong><\/p>\n

      It is obvious that Curai is leaps and bounds ahead of \u201cpatients googling their own symptoms\u201d. The team must deal with several critical questions that I would love to hear more thoughts on.<\/p>\n

        \n
      1. Will patients ever be willing to trust diagnosis\/suggestions from ML driven platforms, without any human intervention?<\/li>\n
      2. What will the regulatory framework look like to govern platforms such as Curai, and where will the accountability lie?<\/li>\n<\/ol>\n

        Will the system ever be able to gain contextual intelligence around a patient (the way a family physician knows your and your family\u2019s complete medical history) and use it to make rational suggestions?<\/p>\n
