-
a Study period was divided into three periods for the purposes of this analysis: empiric therapy containing a penicillin (December 1995-November 1998), transition period (December 1998-November 2002) and empiric therapy with ceftriaxone (December 2002-November 2005).
-
b Includes regimens with ampicillin in combination with chloramphenicol or an aminoglycoside. A small proportion of patients received crystalline penicillin G in place of ampicillin.
-
c Antibiotic therapy was defined as discordant when patients did not receive a β-lactam antibiotic for which the S. pneumoniae isolate was susceptible during the initial 24 hours of hospitalization.
-
d Defined as penicillin MIC >0.06 μg/ml for a pneumococcal isolate from a patient with meningitis.
