BACKGROUND: Ventilator-associated pneumonia (VAP) is common and costly. In a recent randomized controlled trial, the Venner-PneuX (VPX) endotracheal tube system (Qualitech Healthcare Limited, Maidenhead, United Kingdom) was found to be superior to standard endotracheal tubes (SET) in preventing VAP. However, VPX is considerably more expensive. We evaluated the costs and benefits of VPX to determine whether replacing SET with VPX is a cost-effective option for intensive care units. METHODS: We developed a decision analytic model to compare intubation with VPX or SET for patients requiring mechanical ventilation after cardiac operations. The model was populated with existing evidence on costs, effectiveness, and quality of life. Cost-effectiveness and cost-utility analyses were conducted from a National Health Service hospital perspective. Uncertainty was assessed through deterministic and probabilistic sensitivity analyses. RESULTS: Compared with SET, VPX is associated with an expected cost saving of £738 per patient. VPX led to a small increase in quality-adjusted life years, indicating that the device is overall less costly and more effective than SET. The probability of VPX being cost-effective at £30,000 per quality-adjusted life year is 97%. VPX would cease to be cost-effective if (1) it led to a risk reduction smaller than 0.02 compared with SET, (2) the acquisition cost of VPX was as high as £890, or (3) the cost of treating a case of VAP was lower than £1,450. CONCLUSIONS: VPX resulted in improved outcomes and savings that far offset the cost of the device, suggesting that replacing SET with VPX is overall beneficial. Findings were robust to extreme values of key variables.
