[Use of the critical path with the electronic chart system using meropenem, vancomycin, liposome amphotericin B for the febrile neutropenia].

Febrile neutropenia (FN) is a serious complication associated with morbidity and mortality. To manage infections in neutropenic patients, it is necessary to administer empirical antibiotic therapy in a timely and efficient manner. We developed an electronic critical pathway system for a computer-stored medical record system (EGMAIN-GX, Fujitsu), which matches FN patients to either: i) the first-line therapy with meropenem (3 g/day) alone, or ii) the second-line therapy with meropenem plus vancomycin (2 g/day). If patients do not respond to the first-line therapy within 72 hours, then they are provided with the second-line therapy. A total of 28 FN events were treated in 14 patients presenting with hematological malignancies. The mean and median neutrophil counts were 42 (0-300)/microl and 0/microl, respectively. The response rates with the first-line and second-line therapies were 57% and 93%, respectively. There were no serious adverse events. Meropenem is a highly effective treatment for FN. Use of an electronic critical pathway system could ensure that neutropenic patients receive this necessary empiric therapy in a timely manner so as to prevent the serious complications associated with FN.
