Urinary tract infections are a common problem seen in both the outpatient and inpatient setting. For community-acquired UTIs, (KEEPS) is a helpful mnemonic to remember the common pathogens:

Klebsiella (~10%)

E. coli (~80%)

Enterococcus

Proteus mirabilis (5%)

S. saphrophyticus (5-10%) 

NOTE: in the hospital, remember to consider: Pseudomonas, Serratia and Staph aureus!!!
