ABSTRACT Hospital-acquired pneumonia (HAP) contributes greatly to patient mortality and healthcare costs. Studies have shown that aggressive oral care in intensive care units (ICUs) can significantly reduce pneumonia rates, and hospitals have implemented stringent protocols in this setting. However, little is known about the effectiveness of aggressive oral care in reducing HAP in non–intensive care wards, prompting us to conduct a nonrandomized controlled clinical trial. A structured toothbrushing program was provided to an experimental cohort of patients. A control group received usual care. Patient demographics, toothbrushing frequency, and pneumonia diagnosis were recorded over a 3.5-month period. Difference in pneumonia rates was computed using unadjusted and multivariate logistic regression analyses. No significant difference in pneumonia rates between control and experimental groups was found (1.7% versus 1.8%). Toothbrushing rates increased significantly in the experimental group (p = .002) but fell short of protocol frequency. It became apparent that aggressive toothbrushing program implementation requires nursing-led interdisciplinary involvement, more intensive training, a streamlined documentation system, and efficient compliance tracking. Lessons from this study should be used for future large-scale research. A secondary analysis of these data did, however, suggests that increasing toothbrushing rates may have the potential to reduce pneumonia in the non-ICU acute care setting.
