The government must establish medical malpractice insurance.

Currently, medical malpractice insurance is operated by doctors or hospitals, but this should be funded through national tax revenue.
Even now, the government is failing to pay out funds that should be covered by National Health Insurance, but at the very least, the government should provide financial support to ensure that malpractice insurance operates properly.
Only then can we hope to revive the "vital" medical fields; under the current system, the structure is destined for failure.
