Background: The ability to acquire the best evidence efficiently is important for busy healthcare professionals who have to make decisions within a limited time.

All items rated less than 3 by any expert were removed. The items were modified or merged after authors’ discussion considering experts’ comments. When all items were rated >= 3 by all experts with an interquartile range (IQR) of
