University of Pennsylvania Medical Center Guidelines for Antibiotic Use

The susceptibility results are found in three tables, one for inpatients, one for outpatients, and the third for anaerobic bacteria (2007-2008 combined data for HUP and PMC). The pneumococcal, Stenotrophomonas maltophilia and Candida glabrata (and other Candida spp)(2005-2008) susceptibility data for both institutions are now presented on a separate page. In general, the outpatient susceptibility results give a better picture of the frequency of antimicrobial agent resistance of community-acquired pathogens, and the inpatient results of hospital-acquired pathogens. Usually inpatient bacterial isolates are more resistant to antimicrobial agents than are outpatient isolates. However, in some cases, some outpatient clinics care for patients with chronic infections, who have been treated with multiple courses of antimicrobial agents; in this case the outpatient isolates may be more resistant than inpatient isolates.For a another picture of outpatient susceptibility results in a similar population, look at the Presbyterian Medical Center susceptibility profiles. Both HUP and PMC data are available in an Excel spreadsheet.
