While the national standard RT has been established in Iran since 2007, its application has hardly been put into scrutiny. This study aimed at investigating the use of RT standard in assessing EMS in Iran.

Repetitious papers and those presented in conferences were omitted, which left 21 papers published from 2007 to mid-2016 for systematic review. A data collection form was designed. This provided both inclusive information about the papers and indicators used to report RT in each paper (i.e., mean and percentages of RT below 8 min) as well as the use of these indicators vis-a-vis that of the standard. From among the 21 papers focusing on RT, seven (33%) reported RT as percentages of operations performed in
