In the intricate environment of hospital care, patients are vulnerable to a multitude of complications. One such potential complication is hospital-acquired pneumonia (HAP), a prevalent infection in American hospitals, which manifests more than 48 hours post-admission. Notably, the majority of HAP, approximately 65%, occurs in nonventilated patients, causing a condition known as non-ventilator hospital-acquired pneumonia (NV-HAP).
This situation can result in prolonged hospital stays, a greater requirement for mechanical ventilation, and a higher risk of mortality. Hence, it becomes imperative that effective infection prevention measures are undertaken to combat this risk regardless of the unit the patient is in.
One of the key risk factors contributing to the development of pneumonia lies within the sphere of oral care. The oral cavity harbors a plethora of bacterial species, over 700 in fact, and the formation of a dental biofilm can begin within a mere four hours. In individuals with decreased mobility, frailty, or dementia, this biofilm proliferates more significantly. Such oral biofilms, given their bacterial density, make it challenging to ascertain whether colonization occurred before or during hospital admission.
Consequently, efforts should be steered towards reducing pneumonia risk factors both in the community and within healthcare facility walls. By prioritizing comprehensive oral care within hospitals, we can address modifiable risk factors associated with HAP such as dental plaque, bacterial colonization, and the aspiration of secretions. Without appropriate oral care, plaque build-up can invite harmful bacteria that may then be inhaled into the lungs, causing HAP.
A study highlighted that enhancing the frequency of oral care interventions could lead to an 85% reduction in NV-HAP incidence rates. In the context of best nursing practice, it has been recommended by bodies such as the American Dental Association (ADA) that hospitalized patients, particularly elderly individuals, engage in a comprehensive oral care regimen. This includes brushing with a soft-bristled toothbrush multiple times a day and using an antiseptic mouth rinse, sodium bicarbonate or fluoride toothpaste, and a non-petroleum-based moisturizer.
Ultimately, the prevention of HAP requires a multifaceted approach involving a convergence of the right people, products, and processes. Training to build the knowledge, skills, and understanding of nurses and healthcare clinicians is imperative. So too is patient and family education on the importance of good oral care. Likewise, having accessible, easy-to-use products packaged in one location aids in integrating oral care in daily routines. Having reminder signs and other prompts can help in facilitating best practices.
Lastly, ensuring a well-documented and well-executed process for oral care using evidence-based nursing practices is critical in maintaining good hygiene. In sum, a thorough approach to patient oral care is key to mitigating risk factors associated with pneumonia. By fostering an environment of awareness and providing adequate support, our healthcare professionals can optimize patient outcomes and prevent the considerable complication of HAP.
