Hu Xiaoyi, vice-minister of Human Resources and Social Security, recently told reporters that the ministry will fully introduce nationwide social medical insurance for serious diseases within the year. Comments:

Public opinion tends to welcome every move that extends the social security net. Actually, with the social security system covering a high percentage of medical costs, patients will be insensitive to prices and choose expensive treatments that might be unnecessary. This might increase the cost of the social security system and bring huge losses that could lead to its collapse. Moves are needed to prevent this.

At present, it is counties and cities that shoulder the burden of social medical insurance. With the insurance covering serious diseases, their revenues might be insufficient to cover the costs. We call for the authorities to design provincial even national mechanisms to cover the additional costs.

It is a good move to include serious diseases in the social medical insurance, but considering the currently high medical costs, the benefit might be divided among pharmaceutical companies and PR companies. A total reform of the medical industry is needed to lower the costs and create a more reasonable pricing mechanism for the industry. Only with costs under control will this new, welcome move be sustainable.

Rare diseases actually cost much more to treat than general serious diseases - millions of yuan are nothing for their treatment - yet patients with rare diseases get hardly any help without fund-raising activities such as the ice bucket challenge. Will the social medical security consider including rare diseases, too, to save more lives?
