Time savings of weekly versus three-times-per-week administration of erythropoiesis stimulating agents in United States dialysis patients.

OBJECTIVE: Previous research suggests that erythropoiesis stimulating agent (ESA) administration in dialysis is a time-consuming task and switching to less frequently dosed ESAs may offer operational efficiencies. Our objective was to describe and measure the time spent on tasks in the ESA administration process in US dialysis centers, and to estimate potential efficiency gains of using weekly (QW) administration vs three-times-per-week (TIW) administration. METHODS: We conducted a time and motion study of staff time required to prepare, administer and document ESA doses. Dialysis centers using intravenous administration of TIW epoetin alfa (EPO) or QW darbepoetin alfa (DPO) were selected in pairs (one EPO, one DPO) from the same organization to help control for differences in ESA protocols and staffing patterns across organizations. ESA-related tasks were timed by trained observers. Time savings of TIW vs QW administration were estimated. Staff were interviewed about alternate activities that could be accomplished if time were saved in the ESA process. RESULTS: A total of 200 administrations were observed (81 DPO, 119 EPO). A mean of 2.26 (95% CI: 2.1-2.5) minutes per dose were required for ESA administration. ESA process time per administration did not vary significantly between EPO and DPO (p = 0.83). Estimated potential monthly staff time savings for an average facility of 70 patients totaled 23 hours, due to fewer ESA administrations using QW DPO. Patient education and fulfillment of care plans were identified as opportunities for improved care processes that could be implemented if staff time was freed up from the ESA process. LIMITATIONS: Results should not be generalized to other countries, ESAs and/or dosing frequencies. CONCLUSIONS: Switching from TIW EPO to QW DPO can result in time savings due to fewer administrations and provide opportunities to redirect nurse time towards activities aimed at improving patient care.

Staff time and motion assessment for administration of erythropoiesis-stimulating agents: a two-phase pilot study in clinical oncology practices.

BACKGROUND: Erythropoiesis-stimulating agents (ESAs) are used for the management of anaemia in patients with non-myeloid malignancies where anaemia is due to the effect of concomitant myelosuppressive chemotherapy. Assessing the impact of different ESA dosing regimens on office staff time and projected labour costs is an important component of understanding the potential for optimization of oncology practice efficiencies. OBJECTIVES: A two-phase study was conducted to evaluate staff time and labour costs directly associated with ESA administration in real-world oncology practice settings among cancer patients undergoing chemotherapy. The objective of Phase 1 was to determine the mean staff time required for the process of ESA administration in patients with anaemia due to concomitantly administered chemotherapy. The objective of Phase 2 was to quantify and compare the mean staff time and mean labour costs of ESA administered once weekly (qw) with ESA once every 3 weeks (q3w) over an entire course of chemotherapy. METHODS: Phase 1 was a prospective, cross-sectional time and motion study conducted in six private oncology practices in the US based on nine steps associated with ESA administration. Using findings from Phase 1, Phase 2 was conducted as a retrospective chart review to collect data on the number and types of visits in two private oncology practices for patients receiving a complete course of myelosuppressive chemotherapy. RESULTS: In Phase 1, the mean total time that clinic staff spent on ESA administration was 23.2 min for patient visits that included chemotherapy administration (n(chemo) = 37) and 21.5 min when only ESA was administered (n(ESAonly) = 36). In Phase 2, the mean duration of treatment was significantly longer for q3w than qw (53.84 days for qw vs. 113.38 for q3w, p < 0.0001); thus, analyses were adjusted using analysis of covariance (ANCOVA) for episode duration for between-group comparisons. Following adjustment by ANCOVA, qw darbepoetin alfa (DA) patients (n(qw) = 83) required more staff time for ESA + chemotherapy visits and ESA-only visits than q3w patients (n(q3w) = 118) over a course of chemotherapy. Overall, mean total staff time expended per chemotherapy course was greater for patients receiving qw versus q3w DA. Weekly DA dosing was associated with greater projected mean labour costs ($US38.16 vs. $US31.20 [average for 2007-2010]). CONCLUSIONS: The results from this real-world study demonstrate that oncology practices can attain staff time and labour costs savings through the use of q3w ESA. The degree of savings depends on the individual oncology practice's staffing model and ESA administration processes, including those that allow for optimized synchronization of patient visits for ESA and chemotherapy administration. These findings indicate that additional research using standard ESA administration protocols for longer periods of time with a larger number of oncology practices and patients should be conducted to confirm these findings.

The burden of blood transfusion: a utilization and economic analysis--a pilot study in patients with chemotherapy-induced anemia (CIA).

OBJECTIVE: The objective is to measure the burden of blood transfusion of Packed Red Blood Cells (PRBCs) in patients with chemotherapy-induced anemia (CIA) on the institutional outpatient transfusion center. METHODS: This is a retrospective chart review (starting July 1, 2010, working backwards until 120 evaluable patients are accrued) at a single institutional transfusion center in the US. The mean and standard deviation (SD) were calculated for patient's age, pre-transfusion Hgb level, and other transfusion-related activities. RESULTS: One hundred and twenty records were reviewed. The majority included patients who were female (71%), African American (61%), and had either Medicare (48%) or private insurance (39%). The mean patient age was 59 years and the average pre-transfusion Hgb was 7.9 g/dL. The average patient visit to facility ranged from 213 min for one PRBC unit to 411 minutes for three PRBC units. The mean staff time for patient evaluation was 66 minutes. Actual time for transfusion was ∼100 min for each PRBC unit; 90% of patients received two PRBC units. Staff was engaged in direct patient care for an average of 322 min for two PRBC units. The labor cost of transfusion (in 2011 $US) ranged from $46.13-$49.33 per PRBC unit. The estimated fully loaded bundled cost was $596.49 for transfusion of one unit of PRBC. Limitations of the study include: the site included in this study may not be applicable to all sites in practice and the evaluated patient population was varied, with the exception that all patients were treated for some type of malignancy; and the review of blood bank records for 120 patients was not 120 independent events and, as such, may not have adequately captured actual variability. CONCLUSIONS: This analysis quantifies expense in terms of time for administration of the transfusion, as well as costs associated with outpatient blood transfusions.

Erythropoiesis-Stimulating Agent (ESA) Practice Patterns in Patients With Chemotherapy-Induced Anemia (CIA) Treated at Hospital Oncology Clinics.

OBJECTIVES: To characterize erythropoiesis-stimulating agent (ESA) usage initiated in hospital outpatient oncology centers that employ weekly (QW) and every-3-week (Q3W) ESA dosing regimens; describe the frequency of ESA dosing, transfusions, hemoglobin determinations, and anemia-related visits between these 2 regimens; and compare the rates at which inpatient ESA doses are administered on QW versus Q3W schedules. METHODS: This was a retrospective, observational record review evaluating ESA usage in 641 patients from 8 outpatient oncology clinics throughout the United States. Adult patients who initiated myelosuppressive chemotherapy for a documented solid tumor between August 1, 2007 and June 30, 2009 and received their first 3 consecutive outpatient ESA doses on a QW or Q3W schedule were eligible for study inclusion. During a single course of chemotherapy, ESA administrations were recorded as long as ESA therapy was continued on the initial regimen. ESA doses were captured until termination of ESA therapy, until 9 months had elapsed since the first ESA dose, until the patient was switched to another ESA regimen, or until death. ESA administration during inpatient admissions was also recorded. RESULTS: ESA utilization varied between the dosing groups, with fewer ESA doses administered per follow-up month in patients receiving Q3W versus QW ESA therapy (mean, 1 vs 2 doses). Compared to weekly administration, extended-dose ESA therapy also reduced the number of hemoglobin determinations and anemia-related visits without chemotherapy required per follow-up month. Neither the number of transfusions nor the number of packed red blood cell units administered per follow-up month differed between treatment groups. Compared to weekly ESA therapy, Q3W administration reduced costs associated with ESA prescribing and utilization. CONCLUSION: Extended-dose ESA therapy (Q3W dosing) may improve practice efficiency and may be associated with reduced frequencies of hemoglobin determinations and ESA doses required. Q3W dosing may also reduce inpatient ESA utilization by reducing the number of ESA doses required for previously maintained outpatients.

Impact of long-acting growth factors on practice dynamics and patient satisfaction.

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 < 0.01) in all visits and an 85% reduction (p < 0.01) in mean number of doses. For epoetin alfa only versus darbepoetin alfa only, darbepoetin alfa resulted in a 48% reduction (p < 0.01) in mean number of doses. The most common dosage of epoetin alfa was 40,000 U/week (63.6%) and that of darbepoetin alfa was 200 microg every other week (92%), but complete blood counts were obtained weekly. For pegfilgrastim plus darbepoetin alfa versus sargramostim plus epoetin alfa, a 45% reduction (p < 0.01) in total visits and a 77% reduction (p < 0.01) in mean number of doses were noted in the former group. In 69 patients converted to long-acting drugs, 65 actual hours for a single treatment cycle were saved. For patients receiving pegfilgrastim plus darbepoetin alfa, there was a 45% reduction in total clinic visits, 77% reduction in doses, and staff time savings of 1.9 hours/patient/cycle of chemotherapy. Fifty-four patients completed the survey and trended toward neutral in their responses, with moderate disagreement that receiving injections is painful. CONCLUSION: Long-acting growth factors resulted in significant time savings for staff and providers by reducing the number of necessary office visits for drug administration. These time savings can significantly improve the quality of life for patients, as well as nurses, physicians, and caregivers.
