NEW DELHI: A doctor at a hospital in India's capital, New Delhi, was recently tracking a wall of monitors displaying the vital signs of intensive care patients admitted hundreds of miles away when red-and-yellow alerts rang out.

The oxygen flow to a 67-year-old patient had stopped when no critical care doctors were present in a hospital in the northern city of Amritsar.

But the doctor in the New Delhi centre run by Fortis Healthcare quickly issued a set of instructions and stopped the patient from suffering brain damage or death, the Indian hospital chain said in an account of the episode.

Shortage of specialists

India's top private hospitals, seizing on a shortage of critical-care doctors, are expanding into the remote management of intensive care units around the country and, starting this month, in neighbouring Bangladesh too.

India has seven doctors for every 10,000 people, half the global average, according to the World Health Organization.

Data from the Indian Medical Association shows the country needs more than 50,000 critical care specialists, but has just 8,350.

Such a shortage of doctors means small facilities in India's $55 billion private hospital market are ill equipped to provide critical care even as numbers seeking private healthcare rise because the public health system is in even worse shape.

India's largest healthcare chain, Apollo Hospitals Enterprise, and Fortis will this year expand their network of electronic intensive care units (eICUs), scaling up operations thanks to advances in communications technology.

"We want to leverage [doctors] using technology," said K. Hari Prasad, head of hospitals business at Apollo that employs more than 700 critical care doctors.

Apollo, which monitors 200 patients in six states from its only eICU in Hyderabad city, will open three new centres to track 1,000 more patients. Prasad said he is also in talks to extend the service to government hospitals.

Fortis will start remote monitoring of intensive care patients in the Bangladeshi city of Khulna this week, its first such cross-border operation. The hospital chain tracks 350 patients from its New Delhi centre but will start two more eICUs by mid-2017.

Jayant Singh, director of healthcare at Frost & Sullivan India, a consultancy, estimates that eICUs are boosting industry revenues by $220 million a year by giving smaller hospitals the ability to treat critical patients at the hands of top flight intensive-care specialists, even if they are in another city.

India's eICU beds will expand by 15-20 per cent each year from about 3,000 now, Singh said.

Saving lives?

With multiple computer screens inside these high-tech eICUs, doctors suggest treatment procedures after assessing medical history and real-time heart rate charts of patients fighting for their lives in distant facilities.

Doctors recently saved a 30-year-old pregnant woman in a hospital in the southern city of Warangal after her heart stopped beating, assisting a resident doctor not specialised in intensive care to carry out chest compressions through a video link.

"We save about 25 lives a month," said Shamit Gupta, medical director at Fortis' eICU unit.

Hospitals charge between $10 and $30 a day to virtually monitor a patient from their eICUs, with revenues shared between hospitals and companies such as General Electric and Philips that have developed the tracking software.

That comes on top of standard critical care costs of about $200 a day in a small city hospital.

At that price, eICUs do little to address concerns of millions of India's poor patients who often share beds or wait for days to gain admission to a public hospital.

"This technology basically is not bridging the gap between the poor and the rich, but increasing access to specialised healthcare for those who can afford it," Frost & Sullivan's Singh said.
