Bronchoalveolar lavage in the diagnosis of ventilator-associated pneumonia: to quantitate or not, that is the question.
Quantitative bronchoalveolar lavage (BAL) is used to diagnose ventilator-associated pneumonia (VAP). We prospectively compared semiquantitative (SQ) and quantitative (Qu) culture of BAL for VAP diagnosis. Ventilated patients suspected of VAP underwent bronchoscopic BAL. ⋯ Sensitivity (Sn), specificity (Sp), positive (PPV), and negative (NPV) predictive values of SQ culture of BAL fluid for the diagnosis of VAP were 97, 21, 21, and 97 per cent, respectively. Nonquantitative culture of BAL fluid is fairly accurate in ruling out VAP (high Sn and NPV). It however has poor Sp and PPV and using this method will lead to unnecessary antimicrobial use with its attendant complications of toxicity, cost, and resistance.

Outcomes after severe head injury: a National Trauma Data Bank-based comparison of Level I and Level II trauma centers.
Severely head-injured patients require significant resources across the continuum of care. The objective of this study is to analyze the impact of the level of trauma center designation on the outcome of the severely head-injured patient. The National Trauma Data Bank between 2001 and 2006 (NTDB 6.2) was queried for all patients with isolated traumatic head injury and Glasgow Coma Score (GCS) less than 9. ⋯ The comparisons between Level I and Level II trauma centers shows that Level II centers are not inferior to Level I in terms of outcomes and complication rate. Level II trauma centers encounter patients with isolated complex head injury less often but with outcomes and complication rates comparable to that of Level I centers. The transport of head-injured patients should not bypass Level II in favor of Level I.
