Purpose

Low-income countries (LICs) face a growing cancer burden and a pressing need to strengthen cancer care delivery systems. Overall case fatality from cancer is estimated to be 30% higher in LICs than in high-income countries, and adherence to standard treatment guidelines is a critical component of addressing this disparity. Despite several recent international efforts to develop resource-stratified cancer treatment guidelines, little research has been done on their implementation. In 2018, Tanzania’s Ministry of Health will publish a new set of national cancer treatment guidelines for all cancers. The objective of this work is to evaluate the feasibility, adoption, and effectiveness of a theory-informed implementation strategy to facilitate the uptake of guideline-based clinical practice at the national referral center, Ocean Road Cancer Institute (ORCI). Our central hypothesis is that this implementation strategy will be undertaken with fidelity and context-appropriate adaptations and will effectively increase guideline-concordant treatment at ORCI.

Methods

Qualitative data demonstrate that major barriers to guideline-based practice at ORCI include a lack of familiarity with standard treatment guidelines and a culture that prioritizes experience-based expertise over guidelines. We developed a multifaceted intervention to target these barriers using the Capability, Opportunity, Motivation and Behavior/Behavior Change Wheel framework. Our intervention has three phases: distribution of national cancer treatment guidelines in hard and soft copy, with an accompanying publicity campaign; dedicated multidisciplinary trainings for oncology providers and implementation champions; and reinforcement strategies, such as environmental restructuring and point-of-care clinical forms, to promote guideline-based practice. We will use a pre–post design that uses a mixed-methods approach to measure process and outcomes, including clinical data collection, survey administration, and qualitative interviews, focus groups, and field observation.

Conclusion

In Tanzania and other LICs, shifting to guideline-based practice entails a change in clinical culture and behavior, and guideline publication alone is unlikely to result in meaningful change. A theory-informed implementation strategy is the optimal way to ensure the adoption and sustained use of guideline-based practice. Systematic evaluation will allow us to make necessary modifications, disseminate findings, and advance knowledge in the field of cancer treatment guideline implementation in LICs.
