Antibiotic selection is typically empirical, because the results of blood or urine cultures are rarely available by the time a decision must be made. Initial selection should be guided by local antibiotic resistance patterns. Culture results from specimens collected before the initiation of therapy should be checked in 48 hours to determine antibiotic efficacy.
