BackgroundThe clinical pulmonary infection score (CPIS) and bronchoalveolar lavage (BAL) are 2 tools that have been validated to diagnose pneumonia in critically ill patients. However, the role of the CPIS in diagnosing trauma-associated pneumonia (TAP) remains in question.MethodsThis prospective observational study included all trauma patients who were ventilated for longer than 48 hours from September 2008 to September 2009. The CPIS and quantitative culture results from the BAL were collected and used to define pneumonia.ResultsA total of 162 patients were identified. In all, 58 (35.8%) and 104 (64.2%) had a CPIS greater than 5 and a CPIS of 5 or less, respectively. There were 95 (58.6%) patients who had a BAL completed regardless of CPIS. There were 65 patients who met the bacteriologic definition of pneumonia (≥104 colonies/mL), for an overall TAP incidence of 40.1%.ConclusionsThe CPIS is unreliable as a clinical tool to predict a positive BAL at 104 or 105 or higher threshold. Therefore, BAL should be used for the diagnosis of TAP based on clinical rationale and not the CPIS.
