Topic: Hospital-acquired pneumonia commonly develops after 48 hours of hospitalization and can be divided into non-ventilator-acquired and ventilator-acquired pneumonia. Prevention of non-ventilator-acquired pneumonia requires a multimodal approach. Implementation of oral care bundles can reduce the incidence of ventilator-acquired pneumonia, but the literature on oral care in other populations is limited.
Clinical relevance: Use of noninvasive ventilation is increasing owing to positive outcomes. The incidence of non-ventilator-acquired pneumonia is higher in patients receiving noninvasive ventilation than in the general hospitalized population but remains lower than that of ventilator-acquired pneumonia. Non-ventilator-acquired pneumonia increases mortality risk and hospital length of stay.
Purpose: To familiarize nurses with the evidence regarding oral care in critically ill patients requiring noninvasive ventilation.
Content covered: No standard of oral care exists for patients requiring noninvasive ventilation owing to variation in study findings, definitions, and methods. Oral care decreases the risk of hospital-acquired pneumonia and improves comfort. Nurses perform oral care less often for nonintubated patients, as it is perceived as primarily a comfort measure. The potential risks of oral care for patients receiving noninvasive ventilation have not been explored. Further research is warranted before this practice can be fully implemented.
Conclusion: Oral care is a common preventive measure for non-ventilator-acquired pneumonia and may improve comfort. Adherence to oral care is lower for patients not receiving mechanical ventilation. Further research is needed to identify a standard of care for oral hygiene for patients receiving noninvasive ventilation and assess the risk of adverse events.
