Michael Kleinrock, of IMS, explains via email that Rx usage rates have been very consistent for a very long time. Their data goes back to the early 90s, but the collection of age-band data is a relatively recent addition. They haven’t yet produced harmonized figures showing all of their historic data.

Forecast data

In 2008, a paper published by the Department of Health and Human Services gave forecasts for prescriptions dispensed per visit to the year 2030. Three forecasts were made for prescriptions per physician office visit, per hospital/clinic outpatient visit, and per emergency visit. The forecasts are divided into age bands for patients aged 0-44, 45 to 64, and 65 years and older. The forecasts are all based on analysis of the CDC’s National Ambulatory Medical Care Survey (NAMCS) from 1995 to 2004, with trend extrapolation from 2005 to 2030.
