BACKGROUND.: METHODS.: RESULTS.: The initial intervention for INP was performed a median of 27 days (interquartile range, 20–39) after admission without difference between the 3 groups (P = .15). Infection was confirmed in 80% of 92 patients of the clinical group, in 94% of 88 patients of the imaging group, and in 86% of 28 patients of the FNA group (P = .07). Mortality was 19% and was not different between groups (P = .39). CONCLUSION.
