ANTIMICROBIAL SUSCEPTIBILITY PROFILES FOR THE PRESBYTERIAN MEDICAL CENTER OF THE UNIVERSITY OF PENNSYLVANIA HEALTH SYSTEM

January To December 2007

The susceptibility results are found in two tables, one for inpatients and one for outpatients. Combined anaerobic bacteria susceptibility results for PMC and HUP are also available. Also the pneumococcal , Stenotrophomonas maltophilia, and Candida glabrata (and other Candida spp) 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. Note that because of slightly different numbers of isolates tested for different drugs that the susceptibility percentages in some cases have been rounded up by a few percentage points. The HUP susceptibility tables are also available.
