The original version of this Article contained an error in the Results section, where

“We asked each department of the 436 facilities to cooperate in completing the questionnaire, and received responses from 245 facilities (56%), with a total of 941 department heads. Of these, 32 department heads declined to participate in the study and valid responses were obtained from 919 department heads.”

now reads:

“We asked each department of the 436 facilities to cooperate in completing the questionnaire, and received responses from 245 facilities (56%), with a total of 941 department heads. Of these, 22 department heads declined to participate in the study and valid responses were obtained from 919 department heads.”

The original Article has been corrected.
