Managing diabetes during treatment for breast cancer: oncology and primary care providers' views on barriers and facilitators.

Abstract

PurposeDiabetes is a prevalent comorbid condition among many women with breast cancer. The roles and responsibilities of managing diabetes during cancer care are unclear, as oncologists lack interest and clinical expertise and many patients stop seeing their primary care providers (PCPs). Uncertainty around who should manage diabetes for cancer patients can result in gaps in care for survivors. We sought to elicit the perspectives of providers about a novel diabetes care delivery intervention for women undergoing chemotherapy for breast cancer.MethodsWe conducted nominal group sessions with PCPs and breast oncologists across the USA. We introduced a novel care delivery model, which involved a nurse practitioner (NP) specifically trained in diabetes to work within the oncology team to manage diabetes for women during chemotherapy. PCPs and oncologists were asked to identify potential barriers and facilitators to the intervention’s success and then vote on the top three most important barriers and facilitators, separately. Votes were aggregated across sessions and presented as frequencies and weighted percentages.ResultsFrom November to December 2020, two 60-min sessions with PCPs and two 60-min sessions with breast oncologists were held virtually. In total, 29 providers participated, with 16 PCPs and 13 breast oncologists. At the health system level, financial support for the NP-led intervention was identified as the most important barrier across both provider types. Clearly defined roles for each care team member were identified as the most important facilitator at the care team level. At the patient level, lack of cancer-specific diabetes education was identified as an important barrier.ConclusionOur findings underscore the need to engage various stakeholders including policy makers, institutional leadership, care team members, and patients to improve diabetes care for patients undergoing chemotherapy for breast cancer. As such, multi-disciplinary interventions are warranted to increase awareness, engagement, and self-management practices among breast cancer patients with diabetes.Supplementary InformationThe online version contains supplementary material available at 10.1007/s00520-022-07112-4.
