SEOUL -- South Korea will use 10 trillion won ($7.59 billion) in health insurance funds over three years to raise fees doctors receive for treating severe illnesses, the health ministry said on Friday, as a walkout by young doctors strains the health system.

The move will incentivise major general hospitals to focus more on treating severe, emergency or rare diseases, and is part of a push to gradually reduce dependence on trainee doctors who should focus on training, the ministry announced at a briefing.

Thousands of trainee doctors, including interns and resident doctors, walked off the job in February to protest against plans to lift medical student numbers by 2,000 a year to meet what the government projects will be a severe shortage of doctors.

Hospitals which had relied on trainee doctors across multiple medical disciplines have had to turn away patients at emergency rooms or reduce opening hours, while existing doctors have experienced heavier workloads.

Since then, the government has made a series of attempts to reduce the pressures on the medical system due to the young doctors' walkout, including deploying military doctors to assist in hospital emergency rooms, and asking the public to refrain from visiting emergency rooms with non-severe symptoms.

On Friday, the health ministry said major general hospitals providing specialised care will receive a 50% increase in fees for running intensive care units, as well as providing surgical procedures for severe illnesses such as cancer.

Driven by the move, 70% of treatment at such hospitals will eventually be for severe illnesses, up from 50% now, the health ministry said.
