| Abstract | Background: Evidence-based nursing (EBN) offers established benefits; however, its implementation in clinical practice, particularly in intensive care settings, remains challenging. Objectives: To evaluate the effect of an EBN care program on treatment outcomes in intensive care unit (ICU) patients. Methods: This nonrandomized quasi-experimental study was conducted in 2 general ICUs at a hospital affiliated with Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran, between September and December 2025. A total of 70 ICU patients were selected using convenience sampling and allocated to the intervention (n = 35) or control (n = 35) group. The intervention group received a 4-week EBN program (1 in-person session and 7 virtual sessions, each lasting 1.5 - 2.5 hours) plus continuous clinical supervision during care, whereas the control group received routine care. Data were analyzed using independent-samples t-tests, chi-square tests, and repeated-measures analysis of variance (ANOVA). Results: Baseline characteristics were comparable between the groups (P > 0.05). The EBN group had a significantly shorter ICU stay than the control group (18.00 ± 8.21 vs. 26.88 ± 12.40 days; P = 0.001) and a shorter duration of mechanical ventilation (14.88 ± 7.87 vs. 23.74 ± 12.06 days; P = 0.001). The incidences of sepsis (25.7% vs. 62.9%; P = 0.002), ventilator-associated pneumonia (VAP) (40.0% vs. 80.0%; P = 0.001), delirium (28.6% vs. 54.3%; P = 0.029), and urinary tract infection (UTI) (31.4% vs. 71.4%; P = 0.001) were significantly lower in the intervention group than in the control group. Repeated-measures ANOVA showed a significant time × group interaction for Braden Scale scores (P < 0.001), with scores improving in the EBN group and declining in the control group. ICU mortality did not differ significantly between the EBN and control groups (28.6% vs. 45.7%; P = 0.138). Conclusions: The findings of this study suggest that a structured EBN program incorporating targeted education and ongoing clinical supervision may improve clinically important outcomes in ICU patients. However, given the single-center, quasi-experimental design, these findings should be interpreted with caution. Future multicenter randomized trials with longer follow-up and cost-effectiveness analyses are needed to strengthen the evidence base. | en |
