• Background Ventilator-associated pneumonia is a common complication of mechanical ventilation. Backrest position and time spent supine are critical risk factors for aspiration, increasing the risk for pneumonia. Empirical evidence of the effect of backrest positions on the incidence of ventilator-associated pneumonia, especially during mechanical ventilation over time, is limited. • Objective To describe the relationship between backrest elevation and development of ventilator-associated pneumonia. • Methods : It is a nonexperimental, longitudinal, descriptive design was used. The Clinical Pulmonary Infection Score was used to determine ventilator-associated pneumonia. Backrest elevation was measured continuously with a transducer system. Data were obtained from laboratory results and medical records from the start of mechanical ventilation up to 7 days. • Results Sixty-six subjects were monitored (276 patient days). Mean backrest elevation for the entire study period was 21.7°. Backrest elevations were less than 30° 72% of the time and less than 10° 39% of the time. The mean Clinical Pulmonary Infection Score increased but not significantly, and backrest elevation had no direct effect on mean scores. A model for predicting the Clinical Pulmonary Infection Score at day 4 included baseline score, percentage of time spent at less than 30° on study day 1, and score on the Acute Physiology and Chronic Health Evaluation II, explaining 81% of the variability (F=7.31, P=.003).

• Conclusions Subjects spent the majority of the time at backrest elevations less than 30°. Only the combination of early, low backrest elevation and severity of illness affected the incidence of ventilator-associated pneumonia.

Despite strong evidence in the literature on the role of oral care in the prevention of ventilator-associated pneumonia (VAP), nurses continue to view oral care as a comfort measure with low priority and utilize foam swabs rather than toothbrushes. Although an evidence-based oral care protocol existed and best-practice oral care tools were available, the VAP rates had not significantly decreased even though nurses reported providing oral care. OBJECTIVES:
The aim of the study was to determine if an evidence-based practice (EBP) educational program would improve the quality of oral care delivered to mechanically ventilated patients; thereby, reducing the VAP rate. RESULTS:
Improvement in oral health was demonstrated by a decrease in median scores on the Oral Assessment Guide (pre (11.0), post (9.0)). A t-test analysis revealed a statistically significant difference (p=0.0002). The frequency of oral care documentation also improved as demonstrated by a positive shift to the more frequent timeframes. The VAP rates have decreased by 50% following the EBP education Literature Search 4
The implementation of an EBP educational program focused on patient outcome rather than a task to be performed improved the quality of oral care delivered by the nursing staff.
