Health professionals' preferences with the use of pegfilgrastim on-body injector at oncology centers in 8 cities in Colombia.

Background: Febrile neutropenia associated with some chemotherapy regimens can lead to potentially fatal complications and high health care costs. Administration of pegfilgrastim using an On-Body Injector (OBI) may be more convenient for cancer patients and physicians in countries with limited access to high-complexity healthcare. This study aims to describe physician and nurse preferences regarding different options for administration of pegfilgrastim at cancer centers, the chemotherapy schemes for which pegfilgrastim is most frequently prescribed and how healthcare providers prioritize certain administration schemes according to patients' access to healthcare services.

Methods: Observational, descriptive, cross-sectional study and survey, conducted between 2019 and 2020, to describe physician and nurse preferences regarding options for administration of pegfilgrastim at cancer centers, the demographics of the study population and characteristics of participating cancer centers. It included 60 healthcare professionals practicing at oncology centers from 8 cities in Colombia who were contacted and surveyed via telephone. Quantitative continuous variables were summarized using central tendency and dispersion measures.

Results: It was found that 35% of participants are haemato-oncologists, oncologists or hematologists, 30% are general practitioners, and 35% are other healthcare professionals (i.e., nurse, oncology nurse and head nurse). Our study shows that 48% of physicians prefer the use of OBI, particularly in the scheme of 24 h after myelosuppressive chemotherapy administrations. Regardless of patient frailty and travel time to the clinic, over 90% of healthcare providers (HCPs) prefer to prioritize preventing the patient from having to return to the clinic for pegfilgrastim administration as well as to increase healthcare staff availability through the use of OBI.

Conclusions: The present study is the first one in Colombia that sought the reasons behind HCPs' choice to use OBI pegfilgrastim. Our results indicate that most professionals prefer to avoid the patient having to re-enter the care center for pegfilgrastim administration to facilitate access to healthcare for patients; patient characteristics and ease of transport are determining factors for respondents when choosing an option for drug administration. We found OBI is the preferred alternative by most HCPs and a good resource optimization strategy in the context of cancer patients' health care in Colombia.
