Priorities for multimorbidity management and research in cancer: a Delphi study of Australian cancer survivors, clinicians, and researchers

Purpose: Multimorbidity is common in people with cancer and associated with increased complexity of care, symptoms, mortality, and costs. This study aimed to identify priorities for care and research for cancer survivors with multimorbidity. Methods: A Delphi consensus process was conducted. Elements of care and research were based on Australia's National Strategic Framework for Chronic Conditions, a literature review, and expert input. In Round 1, health professionals, cancer survivors, and researchers rated the importance of 18 principles, 9 enablers, and 4 objectives. In Round 2, new elements were rated and all elements were ranked. Results: In Round 1, all elements reached consensus for care delivery; three principles and one enabler did not reach consensus for research and were eliminated. One principle and two enablers were added, reaching consensus. In the final list, 19 principles, 10 enablers, and 4 objectives were included under care delivery; 14 principles, 9 enablers, and 4 objectives were included under research. For care delivery, principles of 'survivorship' and 'self-management' were ranked highest, and 'peer support' and 'technology' were the most important enablers. For research, 'survivorship' and 'coordinated care' were the highest-ranked principles, with 'peer support' and 'education' the most important enablers. Conclusion: Most elements apply to the general population and cancer survivors; however, additional elements relevant to survivorship need consideration when managing multimorbidity in cancer survivors. Implications for Cancer Survivors: Chronic disease frameworks should be more inclusive of issues prioritised by people with, managing, or researching cancer through interdisciplinary approaches including acute and primary care.
