Means testing is a necessary evil to ensure that health-care subsidies go to Singaporeans who deserve them most.

I am pleased to note that under the guidelines, about 60 per cent of workers will receive the full subsidy when they choose to stay in a B2- or C-class ward in public hospitals.

In most countries, health care remains a touchy and emotional issue which does not go down well with the public. I am happy that the policy in Singapore will benefit 60 per cent of Singaporeans, based on the data released by the Ministry of Health.

My concern relates to Singaporeans who fall within the grey zone mentioned by Health Minister Khaw Boon Wan.

This refers to the group of people who have high incomes, but are saddled with exceptional financial difficulties. Means testing may not capture the true financial position in such cases.

While Minister Khaw has given an assurance that he would be flexible on the matter, I am less sanguine. Similar guidelines often cause frustration and delay because of the lack of clarity.

I would rather have clearly spelt out guidelines so that hospital administrators and patients are fully aware of what they mean.
