The Audit Committee has said that a number of cost pressures on the NHS continue, including an ageing population; pharmaceutical costs, which tend to rise by more than the inflation rate—some say that the increases are between 6 and 8 per cent a year; the reduction in junior doctors' hours because of continuing implementation of the working time directive, which reduces their contact with patients; completion of agenda for change; the increasing cost of out-of-hours services; the phasing out of capital-to-revenue transfers; and the termination of capital asset sales for revenue.Those are not all the pressures, but they are some of the main ones.
