Implementing integrated diabetes care in oncology: A scoping review of clinical effectiveness, implementation strategies, and costs Running title: Implementing Diabetes Care in Oncology
This scoping review of eleven studies indicates that integrated multidisciplinary diabetes care in oncology settings yields clinical benefits such as improved self-care and reduced hospitalizations, though successful implementation relies on strategies like role revision, structured pathways, and dedicated resources to overcome barriers related to cost, communication, and care prioritization.

Cancer and diabetes are two of the most common chronic conditions affecting adults today, and they frequently appear together in the same person. While they are distinct diseases, they share a complex relationship: having diabetes can increase the risk of developing cancer, and the treatments used to fight cancer can sometimes make blood sugar levels harder to control. When a patient faces both illnesses at once, the medical care they receive often becomes fragmented. Specialists who treat cancer and doctors who manage diabetes may work in separate worlds, leaving the patient to navigate conflicting advice, missed appointments, and a lack of coordination. This disconnect can lead to serious complications, such as emergency room visits or treatments that are less effective than they could be. The central question for modern medicine is not just whether these two conditions can be treated together, but how to build a system where the care flows smoothly, ensuring that a patient's diabetes is managed with the same urgency and expertise as their cancer.
A team of researchers set out to map the current landscape of this challenge. They conducted a broad review of existing studies to see what happens when hospitals try to integrate diabetes care directly into cancer treatment. Instead of looking for a single perfect solution, they gathered evidence from eleven different studies to understand what works, what gets in the way, and what it costs. Their goal was to move beyond the idea of simply telling doctors to "collaborate more" and instead identify the specific structures and strategies that make integrated care a reality. By examining real-world examples, they sought to find a blueprint for how medical teams can work together to support patients who are fighting two battles at once.
The researchers found that when integrated care is successfully implemented, the results for patients are tangible and positive. In the studies they reviewed, patients who received coordinated support saw improvements in their blood sugar levels and were better able to manage their own health through diet and daily monitoring. Perhaps most importantly, these patients visited the hospital less often. One large study showed that over a three-year period, patients who received diabetes education and coordinated care had significantly fewer hospital admissions compared to those who did not. This suggests that proactive, outpatient support can prevent the crises that usually force patients into emergency rooms. The care models that worked best involved bringing new roles into the cancer team, such as pharmacists or specialized nurses who could focus specifically on diabetes management, ensuring that blood sugar issues were addressed before they became emergencies.
However, the path to this integrated care is not without obstacles. The researchers discovered that the biggest hurdles are often not medical, but organizational and human. Many cancer specialists feel uncomfortable managing diabetes because it falls outside their specific training, while primary care doctors may feel ill-equipped to handle the side effects of cancer treatments. This creates a gap where patients fall through the cracks. Patients themselves face significant barriers; the physical toll of cancer treatment, such as fatigue and loss of appetite, often makes it difficult to prioritize diabetes management. Financial constraints can also prevent patients from buying the healthy foods needed to control their blood sugar. Furthermore, the cost of running these new programs and the lack of clear communication between different medical teams can stall implementation. The review highlighted that successful programs relied on clear roles, dedicated staff members who championed the cause, and flexible options like telehealth to make care more accessible.
Despite these promising signs, the researchers caution that the evidence is still limited. The studies they reviewed were often small, conducted in specific urban hospitals, and varied widely in how they were designed. While the data suggests that integrated care saves money by reducing hospital stays, the financial proof is not yet definitive across all settings. The review concludes that while the clinical benefits are clear, the field is still in its early stages of figuring out how to scale these solutions. The most effective strategies identified involve redefining the roles of healthcare providers, creating structured pathways for patients to follow, and investing in education for both patients and staff. Ultimately, the work suggests that the future of treating patients with both cancer and diabetes lies in breaking down the walls between specialties, building teams that communicate clearly, and designing systems that support the whole person rather than just one disease at a time.
