No, the services did not decrease. What happened is that the growth in intensity decreased. The growth rate decreased, not the health care.
When we make forecasts, we use growth rates. Take the hypothesis that care for the elderly is generally more intense, given that some say that this care sometimes includes therapeutic obstinacy, and one hears other such arguments. This seems to indicate that the intensity of care given to the elderly increases systematically.
However, if the intensity of care is increasing, it is not increasing as quickly as health care given to other age groups. In other words, the rate of increase in the future will go up much more quickly for people between the ages of 45 and 64 than for people aged 65 and over.
So just because the rate of increase is not as high does not mean that fewer health care services are being provided. The rate of increase is not as fast, but it does not mean there are fewer services.
