Fever Charts (part 1) - extracting data from fever charts and making digital graphs

Why - because these fever charts (and many more charts) are easily available everywhere and once digitized this will help to collect a huge amount of data and explore it for medical and AI research. So starting small with fever charts to explore the possibility.

Collaborating with friends having an engineering background, because just medical school itself is tough to manage for me so can't get hands dirty nowadays on coding (I like python). Names of collaborators and links to project updates will be updated here later.


A sample fever chart -



This is how I started doing it manually and made a tutorial in the hope that other medicos and patients can also do it after following the steps
http://classworkdecjan.blogspot.com/2017/08/using-fever-chart.html






It was tiring to do manually so I could not manage to do frequently.



I tried the above sample image with google OCR (vision API) and here are the screenshots







A simpler way could be that just in table form write date time and temp. and a chart generated automagically by OCR, but let see how far this idea goes for using the real world available and regularly generated paper records.

Problem statement shared with engineering folks - generate a graph from this image. without manual inputs. if better handwriting, or legends or anything can improve then humans may try that, but best if the algorithm does more work and less expectation from the human. it's ok to make a very inefficient project, we can improve. only need the legend values + graph + date. (rest all data can be ignored for now)

Solutions:
1- one easy hack can be, writing temp. values as legends on graphs.

comments are welcome!

Stethoscope Hack

Tutorial

Requirement:-
1- Any low-cost stethoscope
2- A cheap earphone with microphone
3- Any mobile with a voice recorder app
4- Silent place to avoid noise during recording
6- VLC software to convert audio in mp3 if required
5- Audacity software to see the waveform and modify sound if needed (can be ignored).

Steps:-
1) Break open microphone gently
2) Pull out stethoscope bulb from tube (easy in cheap stethoscope)
3) Connect the microphone at the stethoscope bulb hole
4) Plug earphone in mobile and start voice recorder app
5) Auscultate and record sounds that need to be stored/shared

Go to recorded sound and share/store with the consent of patient/person and as required to tackle patient's needs.

can also
6) Open VLC and go to File -> Convert -> Select Audio -> Convert to MP3 and Save/Store (NDHB Blueprint in India accepts MP3 format as standard for sharing audio https://mohfw.gov.in/sites/default/files/National_Digital_Health_Blueprint_Report_comments_invited.pdf )

7) Open Audacity and modify sound for any analysis needed. (Much to explore here for me, will update findings.)






VR ART in EHRs



Project details


Live demo




Medicine is not just Science but also an Art 




Where patient present to us as pieces of puzzles sharing the story where we take pieces to join and fit patterns to ones we have already seen 




Slowly the pictures stary getting clear and we may reach a diagnosis, there may be uncertainty still and also more complexity possible giving us no clue many times





when we fit and feel to have identified it matching to any that we can proceed with but many times we are clueless but time, placebo and various factors keep playing their role and healing the person, we also try best from what we know and we also discover more from the complexity.







The major part of the art of practice of medicine is not just dealing with uncertainty but more importantly the EMPATHY for patients, understanding them, their needs and their values while also focusing on whole life events to analyse data and find best possible way to help



we are showing a VR based project where womb to tomb EHR data is recorded and along with it various events recorded in artistic way to deliver patient's perspective more clearly and precisely





The Scene in Virtual Reality is interactive and immersive, left the 7 dots show different stages of life and on right, they show different artistic aspects delivering information to the EHR analyst who may be a doctor or an evolved artificial agent.















This is a scene inside the project for a demo purpose showing objectively the measurement on the left and subjectively relevant information on right (in this case art by Rabindranath Tagore)










and all records have discussion on patient-centred problems





where someday when large dataset of many cases and discussions around it will be there, this big data will help us gain better insights and so be able to help better and hopefully will help evolve the AI too for same.
