Quality of care in the course of subcutaneous versus intravenous trastuzumab administration in patients with breast cancer: an integrated time–motion study with mixed-methods research

Abstract

Objectives This study aimed to compare the time required and concerns raised by various perspectives of participants regarding administering subcutaneous and intravenous trastuzumab for patients with breast cancer (BC).Design This observational time–motion study design with mixed-methods research (cross-sectional surveys and semistructured interviews) was conducted. The time spent on preparing or administering trastuzumab by different healthcare professionals (HCPs) was recorded. The data were analysed by descriptive/inferential statistical analyses, followed by thematic analyses.Setting Outpatient and inpatient administration units of a single medical centre in Taiwan.Participants The study included patients with early-stage BC who received subcutaneous or intravenous trastuzumab (n=93), and HCPs including two attending physicians, a nurse practitioner, two pharmacists and two nurses.Result Based on the perspectives of patients and HCPs, the subcutaneous form of trastuzumab was more efficient, less expensive and produced less discomfort in outpatient units than inpatient units. More participants preferred the subcutaneous form over the intravenous form in both outpatient and inpatient units. Pharmacists and nurse practitioners spent threefold more time on patients when preparing and administering the intravenous form in both outpatient and inpatient units. The concerns raised by patients and HCPs varied in certain aspects, including the injection skills, speed, mental distress (eg, needle phobia) and pain associated with the subcutaneous form. Almost all patients preferred receiving the subcutaneous form in outpatient units after the initial COVID-19 outbreak.Conclusion Patients with early-stage BC preferred receiving subcutaneous trastuzumab in outpatient units rather than inpatient units or the intravenous form before and after the COVID-19 outbreak. Such findings may serve as real-world evidence to facilitate better quality of care regarding administration of subcutaneous or intravenous trastuzumab in medical settings, and its feasible resolutions to balance the quality, concerns and efficiency of anticancer administration during the COVID-19 pandemic.
