Abstract
In a retrospective study designed to gather information in a region with high antimicrobial resistance, the outcomes of 216 episodes of laboratory-confirmed pneumococcal bacteremia treated in Hong Kong between 1995 and 2001 were assessed. The patients had a mean age (±standard deviation) of 40±33.7 years. In all patients, the clinical diagnosis was confirmed by isolation of Streptococcus pneumoniae from blood (n=216), cerebrospinal fluid (n=7) and/or other sterile sites (n=12). Penicillin nonsusceptibility was found in 37.5% of the isolates (20.8% intermediate and 16.7% resistant). Penicillin nonsusceptibility was not a risk factor for inpatient mortality (p=0.7), nor did it affect duration of fever (p=0.4), requirement for intensive care unit admission (p=0.4) or development of suppurative complications (p=0.2). Advanced age (OR 11.3, 95%CI 4.5–28.2, p<0.01), critical illness (OR 11.3, 95%CI 4.5–28.2, p<0.001) and discordant therapy (OR 4.3, 95%CI 1.7–10.9, p<0.002) involving agents with poor anti-pneumococcal activity (but not penicillins and broad-spectrum β-lactam agents) were significantly associated with mortality.
