South Korea raises health alert to 'severe' over doctors walkout

South Korea raised its health alert to the highest level on Friday after a mass walkout by trainee doctors this week, while the prime minister said public hospitals would extend working hours to respond to growing strains on the medical system.

Almost two-thirds of the country's young doctors have walked off the job to protest a government plan to admit more students to medical schools, forcing hospitals to turn away patients and cancel procedures, and raising fears about further disruption to the medical system should the dispute drag on.

"The operation of public medical institutions will be raised to the maximum level," Prime Minister Han Duck-soo said at the opening of a disaster management meeting.

Public hospitals will extend operating hours and will also open on weekends and holidays, he said.

So far, more than 8,400 doctors have joined the walkout, the health ministry said, equivalent to about 64% of the entire number of resident and intern doctors in South Korea.

While they represent a far smaller fraction of the country's 100,000 doctors overall, trainee doctors make up a big portion of the staff at teaching hospitals, more than 40% in some cases, and play a key role in the daily operations.

Their role is especially pronounced in emergency rooms, intensive care units and operating rooms at the large hospitals, which are visited by patients referred to them by secondary hospitals and private practice clinics. Larger hospitals rely excessively on trainee doctors in part for cost reasons.

The growing pressure on hospitals prompted the government to raise its health alert to "severe" from "cautious" as of Friday.

Emergency departments in South Korea's biggest hospitals have been squeezed since trainee doctors began leaving
