Objective. To quantify time expended, patient satisfaction, and econometrics associated with short-acting (sargramostim, epoetin alfa) and long-acting (darbepoetin alfa, pegfilgrastim) growth factors. Design. Retrospective resource utilization and prospective two-phase observational study. Methods. During week 1, time-motion measurements related to patient treatment and drug preparation were collected for scheduling; check-in; phlebotomy; laboratory; and drug preparation, administration, and recording. Drug utilization for one chemotherapy cycle during weeks 2 and 3 was assessed for sargramostim, pegfilgrastim, epoetin alfa, darbepoetin alfa, sargramostim plus epoetin alfa, and pegfilgrastim plus darbepoetin alfa. Patients completed a satisfaction survey. Results. Among 140 patients (mean age 58 yrs), mean chemotherapy cycle duration was 19 days. A total of 268 events were observed. Mean total staff time/patient visit for drug administration was 22.1 minutes, with most time spent on scheduling (5.5 min) and drug preparation, administration, recording (5.2 min). For sargramostim only versus pegfilgrastim only, pegfilgrastim resulted in a 37% reduction (p

Study Objective. To compare rates of adverse events with filgrastim versus sargramostim when given prophylactically to patients receiving myelosuppressive chemotherapy. Design. Retrospective review with center crossover. Setting. Ten United States outpatient chemotherapy centers. Patients. Four hundred ninety patients treated for lung, breast, lymphatic system, or ovarian tumors. Intervention. Prophylactic use of filgrastim or sargramostim, with dosages at investigator discretion. Measurements and Main Results. The frequency and severity of adverse events and the frequency of switching to the alternative CSF were assessed. There was no difference in infectious fever. Fever unexplained by infection was more common with sargramostim (7% vs 1%, p
