Cost-effectiveness issues in ventilator-associated pneumonia.

Ventilator-associated pneumonia has attracted considerable interest as a subject of clinical efficacy assessment research. This article summarizes recommendations made by the United States Public Health Service Panel on Cost-Effectiveness in Health and Medicine and by a panel convened by the American Thoracic Society to address economic analyses in critical care. The following recommendations are made for the performance of cost-efficacy studies in ventilator-associated pneumonia. For mortality-based studies, only data from prospective and blinded randomized trials are suitable for analysis. For cost-minimization studies, observational studies may be useful but should use rigorous matching schemes. Estimates for the quality of life of patients surviving an episode of ventilator-associated pneumonia should be based on the disease that required mechanical ventilation or compared to data available for survivors of the respiratory distress syndrome, whichever diagnosis provides a lessened quality of life. Within an individual intensive care unit the greatest cost savings come from constructing a cohesive and unified approach to many issues seen in the unit.
