University of Pennsylvania Medical Center Guidelines for Antibiotic Use
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.
