The term "medical inflation" is often used quite loosely and is sometimes taken to include increases in cost not solely driven by changes in price. For example, the cost of certain services may increase due to the adoption of more costly technology but this technology may have been introduced to facilitate improvements in patient outcomes and/or increased activity levels. Therefore, when analysing the increase in healthcare costs over a number of years it is difficult to disentangle costs associated with increased activity and improvements in quality from price inflation per se. Problems in measuring medical inflation are experienced in all health systems due to the fact that the healthcare market is very different from other markets since public provision and subsidisation mean that prices tend not to reflect actual costs. These measurement difficulties mean that, unfortunately, in response to the Deputy's question there is no reliable estimate of medical inflation in the Irish public health care system for 1998 or 1999. Nevertheless, the evidence that is available would suggest that, both here and internationally, inflation within the health sector is higher than the average rate of price increase in the wider economy. This would be particularly the case in relation to acute hospital services and drug schemes where the influence of technology is most pronounced. For example, the increase in the acute hospital sector over the period 1993 to 1998 was 46 per cent while the increase in the consumer price index over the same period is just 12.5 per cent. This increase for the acute hospital sector would include increases in activity, quality and increase in pay and non-pay costs.
