^aPercentages of shifts in follow-up that adhere to the guideline recommendations for each indicators
^bOdds ratio for improvement in follow-up period for the intervention group compared to baseline period
^cBed occupancy rate adjusted for type of shift, month of the year, availability emergency bed, and academic/teaching or non-teaching unit. Nurse-to-patient ratio adjusted for type of shift, month of the year, ratio of newly admitted mechanical ventilated patients in a shift and academic/teaching or non-teaching unit
^dRatio of odds ratios for improvement in follow-up between groups, calculated as odds ratio of the intervention divided by the odds ratio of the control group
