In a randomized controlled trial, towards computerized medication reviews with the STRIP-assistant, the authors hypothesize that having a group of users perform a similar task over a prolonged period of time will lead to improvements in efficiency of that task. Three expert teams, consisting of an independent physician and an independent pharmacist, conducted 150 computerized medication reviews on patients in 13 general practices located in Amsterdam, the Netherlands. The average time in minutes required to conduct medication reviews up to the first quartile was 20 minutes (SD = 9.00), while the time from the third quartile up was 10 minutes (SD = 6.13). This leads the authors to conclude that the amount of time users needed to perform similar tasks decreased significantly as they gained experience over time.
