Ai-based test to help de­tect shock in chil­dren could save many lives

NEW DELHI: A team of In­dian re­searchers has de­vel­oped a ther­mal imag­ing and ar­ti­fi­cial in­tel­li­gence-based test that pre­dicts set­ting-in of haemo­dy­namic shock -- in­suf­fi­cient oxy­gen sup­ply to or­gans lead­ing to multi-or­gan fail­ure -- in chil­dren even 12 hours be­fore doc­tors can clin­i­cally di­ag­nose it. The de­tec­tion of shock can pre­vent or­gan fail­ure and save lives.

The shock in crit­i­cally ill pa­tients can set in due to var­i­ous con­di­tions, in­clud­ing heavy in­ter­nal bleed­ing and se­vere blood in­fec­tion called sep­sis that leads to re­stricted blood flow and a re­sult­ing lack of oxy­gen sup­ply to or­gans and tis­sues, caus­ing death. Sep­sis is one of the top three causes of neona­tal (till end of first month) deaths in In­dia, with the neona­tal mor­tal­ity rate (NMR) be­ing 28 per 1000 live births. The new re­search, pub­lished in the jour­nal Na­ture’s Sci­en­tific Re­port on Jan­uary 14 this year, has been tested at the pae­di­atric in­ten­sive care unit (PICU) of Delhi’s All In­dia In­sti­tute of Med­i­cal Sciences (AIIMS) for about a year and a half with a suc­cess rate of of 69% in de­tect­ing shock 12 hours in ad­vance.

Chil­dren in the age group of 10 days to 15 years in the AIIMS PICU were tested for the study ti­tled “Pre­dict­ing Haemo­dy­namic Shock from Ther­mal Im­ages us­ing Ma­chine Learn­ing”. The In­draprastha In­sti­tute of In­for­ma­tion Tech­nol­ogy, Delhi, (IIIT-D) and AIIMS col­lab­o­rated on the five-year project that will go on till 2020.

“Since shock is a lead­ing killer of chil­dren in ICUS, the theme of my project was how to de­tect it early so that treat­ment can be started soon enough. We de­vel­oped a tool that com­bines read­ing of tem­per­a­ture pat­terns over the body us­ing ar­ti­fi­cial in­tel­li­gence,” said Dr Tavpritesh Sethi, a fac­ulty at IIIT-D and a Wel­come Trust fel­low at AIIMS.

“We will also be do­ing pi­lot tri­als from this Au­gust un­til July 2020 to get an idea of the num­ber of lives saved through this. Right now it is for chil­dren, but it can be up­dated for adults,” said Sethi.
