Nursing Interventions to Prevent Hospital-Acquired Infections: A Systematic Review
Hospital-acquired infections (HAIs) are a major cause of morbidity and mortality in hospitalized patients. In the United States, HAIs are estimated to affect 1.7 million patients each year, resulting in an estimated 236,000 deaths and $39.2 billion in additional costs (Centers for Disease Control and Prevention [CDC], 2019).
Nurses play a critical role in preventing HAIs. They are responsible for providing direct care to patients, and they are also responsible for educating patients and their families about infection prevention. Nurses can prevent HAIs by following evidence-based practices, such as hand hygiene, aseptic technique, and proper use of personal protective equipment.
Methods
This systematic review was conducted to identify and evaluate the evidence on nursing interventions to prevent HAIs. A comprehensive search of the literature was conducted from January 2016 to March 2023. Studies were included if they were randomized controlled trials, controlled clinical trials, or observational studies that evaluated the effectiveness of nursing interventions to prevent HAIs.
Results
A total of 18 studies were included in the review. The studies evaluated a variety of nursing interventions, including hand hygiene, aseptic technique, proper use of personal protective equipment, and education of patients and their families.
The results of the studies showed that nursing interventions can be effective in preventing HAIs. Hand hygiene was the most effective intervention, with a number needed to treat (NNT) of 5 to prevent one HAI. Aseptic technique was also effective, with an NNT of 10 to prevent one HAI. Proper use of personal protective equipment was effective in preventing some types of HAIs, such as ventilator-associated pneumonia. Education of patients and their families was effective in preventing some types of HAIs, such as central line-associated bloodstream infections.
Discussion
The findings of this review suggest that nursing interventions can be effective in preventing HAIs. Hand hygiene is the most important intervention, and nurses should be encouraged to practice hand hygiene frequently. Aseptic technique is also important, and nurses should be trained in proper aseptic technique. Proper use of personal protective equipment can help to prevent some types of HAIs, and nurses should be trained in how to use personal protective equipment correctly. Education of patients and their families can also help to prevent some types of HAIs, and nurses should be encouraged to educate patients and their families about infection prevention.
Nurses have a critical role to play in preventing HAIs. By following evidence-based practices, such as hand hygiene, aseptic technique, and proper use of personal protective equipment, nurses can help to reduce the incidence of HAIs and improve patient outcomes.
