Mr. Tony O'Brien:

We had an obligation to send the letters. The over-70s medical card is distinct from all other medical cards in that it is determined on the basis of gross income only. The only information we have is on gross income, whereas all other medical cards are issued based on the balance of income versus expenditure. Consequently, in the case of the over-70s we can see, based on simple information fields, whether a person has a gross weekly income in excess of €900 a week for a married couple or €500 a week for a single person. This can be used to trigger a review process. In all other cases the information required to determine eligibility in terms of undue hardship is far more complex and can only be obtained from the individual. Consequently, the review process essentially relates to a very large proportion of the population. As has been outlined in the reports, we are required to ensure a person remains eligible at all times, not just on a particular date or for a particular period of time.
