Implementing Effective Oral Care Practices for Acutely and Critically Ill Patients

Scope and Impact of the Problem:

Oral hygiene is a fundamental right of all patients and plays a crucial role in preventing hospital-acquired infections. Proper oral hygiene practices maintain health and prevent infection, notably reducing the incidence of hospital-acquired pneumonia (HAP), the most prevalent nosocomial infection. Inadequate oral care puts patients at increased risk for HAP, which affects approximately 1% of hospitalized patients and 10% of those receiving invasive mechanical ventilation.¹ Epidemiologic studies indicate that 35% of patients with HAP have ventilator-associated pneumonia (VAP), whereas 65% have nonventilator-associated pneumonia (NV-HAP).^2,3

The oral cavity serves as a reservoir for pathogenic microorganisms in hospitalized patients. These pathogens can replicate rapidly in the absence of routine care and can migrate into the lower respiratory tract through microaspiration, leading to HAP. Health care providers can significantly reduce this microbial burden by implementing evidence-based oral care protocols. These protocols should be viewed as an infection-prevention strategy — rather than as a comfort measure only — aimed at improving patient outcomes by reducing the risk for HAP.⁴
