A systematic review of nurse-led weaning protocol for mechanically ventilated adult patients.
Nursing in Critical Care 2019 March
OBJECTIVES: The aim of this systematic review is to synthesize the current best evidence for the effectiveness of weaning protocols led by nurses compared with usual physician-led care.
BACKGROUND: Protocol-directed weaning has been shown to reduce the duration of mechanical ventilation. Studies have reported that a weaning protocol administered by nurses leads to a reduction in the duration of mechanical ventilation and has a major effect on weaning outcomes. This can have especially positive consequences for critically ill patients.
STUDY DESIGN: Systematic review with meta-analysis.
SEARCH STRATEGY: The databases CINAHL, PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched from as far back as the database allowed until January 2016.
INCLUSION AND EXCLUSION CRITERIA: Searches were performed to identify the best available evidence including quantitative studies of nurse-led weaning protocols for mechanically ventilated adult patients. We excluded all studies of weaning protocols implemented by non-nurses and non-invasive mechanical ventilation and studies that addressed patient populations younger than 18 years of age.
RESULTS: The database searches resulted in retrieving 369 articles. Three eligible studies with a total of 532 patients were included in the final review. Pooled data showed a statistically significant difference in favour of the nurse-led weaning protocol for reducing the duration of mechanical ventilation (mean differences = -1.69 days, 95% confidence interval = -3.23 to 0.16), intensive care unit length of stay (mean differences = -2.04 days, 95% confidence interval = -2.57 to -1.52, I2 = 18%, and p = 0.00001); and hospital length of stay (mean differences = -2.9 days, 95% confidence interval = -4.24 to -1.56, I2 = 0%, and p = 0.00001).
CONCLUSION: There is evidence that the use of nurse-led weaning protocols for mechanically ventilated adult patients has a positive impact on weaning outcomes and patient safety.
RELEVANCE TO CLINICAL PRACTICE: This review provides evidence supporting intensive care unit nurses' crucial role and abilities to lead weaning from mechanical ventilation.
