Our results confirmed the positive effects of nursing interventions based on the proposed guidelines on the incidence of VAP and its diagnostic indicators, with lower mean temperature and white blood cell count, and higher P/F ratios in the intervention group. The overall post-intervention mean MCPIS score was also lower in the intervention group, indicating the effectiveness of the intervention in the prevention of VAP. Yekefallah et al., in a study of investigate strategies for preventing VAP in ICU patients, have shown that effective suction of airway secretions and saliva reduces the incidence of VAP [Babaei et al. have also reported that a caring protocol including adjusting the cuff pressure at about 20 cmH2O, continuous suctioning of subglottic secretions, and keeping the head of the bed at 45° could keep the mean MCPIS lower in the intervention group than the patients who did not receive such cares [In the present study, the implementation of an infection prevention guideline could not significantly affect the use of antibiotics, peptic ulcer prophylaxis, and DVT prophylaxis. Previous studies have reported conflicting results in this regard. Righy et al. showed that the implementation of infection prevention guidelines did not affect the prophylactic use of antibiotics [
