In a surprising turn of events, researchers have discovered a cost-effective method that could reduce pneumonia rates in hospitalized patients—and it’s as simple as brushing teeth.
A study conducted by experts from Brigham and Women’s Hospital and Harvard Pilgrim Health Care Institute delves into this finding, revealing how a daily toothbrushing routine can make a significant difference in patient health.
Published in JAMA Internal Medicine, the study analyzed data from 15 randomized clinical trials involving over 2,700 patients.
The results indicated that those who brushed their teeth daily experienced lower rates of hospital-acquired pneumonia, particularly among patients on mechanical ventilation.
Michael Klompas, MD, MPH, the study’s corresponding author, emphasized the potential life-saving impact of this discovery.
Regular toothbrushing in hospitals, he noted, is not only practical but also incredibly affordable—a rarity in hospital preventative care.
Hospital-acquired pneumonia is a common issue, often occurring when bacteria from the mouth infect the lungs. This is especially problematic for patients with weakened immune systems or those experiencing frailty.
Regular toothbrushing can reduce the mouth’s bacterial load, thus decreasing the likelihood of developing pneumonia during a hospital stay.
The researchers conducted a thorough review and meta-analysis to understand the relationship between daily toothbrushing and hospital-acquired pneumonia.
They sifted through clinical trials worldwide that compared the effects of regular oral care with and without toothbrushing on pneumonia rates and other health outcomes.
Their findings were clear: daily toothbrushing significantly reduced the risk of hospital-acquired pneumonia and ICU mortality.
Additionally, patients in the ICU who brushed their teeth had shorter stays on mechanical ventilation and in the ICU overall.
While most of the studies reviewed focused on adult ICU patients, only two examined the impact of toothbrushing in non-ventilated patients. More research is needed to determine if the benefits of toothbrushing extend to this group.
Klompas hopes that these findings will lead to new hospital policies ensuring regular toothbrushing for patients. If a patient cannot brush their teeth, he suggests that a care team member assist them.
This study highlights the power of simple, everyday actions in enhancing patient care and preventing serious health complications.
Toothbrushing, often overlooked in hospital settings, now emerges as a key player in maintaining patient health and potentially saving lives.
