Abstract

PURPOSE: Practice guidelines recommend the prophylactic use of granulocyte colony–stimulating factors (G-CSFs) in patients with high risk of febrile neutropenia, but evidence suggests that G-CSFs are frequently overused. The objectives of this study were (1) to determine the prevalence and prescribing patterns of G-CSF and (2) to evaluate the impact of a program initiative on G-CSF prescribing patterns, adherence to guidelines, and mortality. METHODS: In this retrospective cohort study, data were used from the electronic health records of patients with metastatic colorectal cancer who received care at a multicenter oncology practice network during two time periods: July 01, 2013, to December 31, 2014, and July 01, 2017, to December 31, 2017. Beginning 2016, a site-wide program initiative that involved educational materials, appropriate nonuse recommendations, and prior authorization was introduced in the oncology practice network with an aim of reducing G-CSF overutilization. Descriptive statistics, t tests, and chi-squared tests were employed to analyze program impact. RESULTS: There were 3,426 chemotherapy regimens corresponding to 2,968 patients. There were a total of 387 (11.3%) G-CSF–treated patients and 3,095 G-CSF administrations during the study period. G-CSF use was significantly lower in the postperiod, compared with the preperiod ( P < .0001). Adherence to guidelines was significantly higher in the postperiod, compared with the preperiod ( P < .0001). Mortality rates did not significantly differ between the two time periods. CONCLUSION: This study demonstrates that policy initiatives have the potential to positively affect G-CSF prescription patterns and promote guideline adherence. These findings could help prescribers adopt a cost-effective approach in patients with metastatic colorectal cancer, leading to enhanced clinical practice and value-based care.
