University of Pennsylvania Medical Center Guidelines for Antibiotic Use

The susceptibility results are found in two tables, one for inpatients and one for outpatients (HUP and PPMC combined). Combined anaerobic bacteria susceptibility results (2007-2008) for PMC and HUP are also available. Also the pneumococcal (Jan-Dec 2012), Stenotrophomonas maltophilia, enteric pathogens (2011-2012), Candida species (2011-2012) and rapidly growing mycobacteria 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. The HUP susceptibility tables are also available.
