Two synthesis maps represent clinical cancer processes and the patient experiences associated with the processes. The maps were constructed in an iterative design and research process by the OCAD University Health Design Studio for CPAC, as part of a larger collaboration to identify evidence-based opportunities for system-level change in cancer diagnosis to improve patient experience and clinical processes across Canada. The maps present an integration of current knowledge from clinical practice and patient experiences drawn directly from interviews and workshops with patient advisors and primary care/cancer clinicians.
The Clinical Process Map of Canadian Cancer Pre-Diagnosis (Clinical) map represents the complex steps of diagnosis typical of patients living within three geographic regions, for three cancer sites that represent a much wider variety of cancers than can be depicted here. The Patient Experience in Cancer Pre-Diagnosis (Patient) map presents three distinct pathways for the same cancers. The Patient map is presented as a metaphorical maze, consistent with the psychosocial experience of patients struggling with these cancers, as informed by patient advisors in interviews and workshops.
The primary purpose of both maps is to demonstrate the relative real-world complexity of cancer diagnosis processes as understood by the stakeholders of diagnosis, patients and clinicians. The maps reveal the variability of access to care across geographies, indicating habitation as one of the significant social determinants of health outcome. While there are other determinants, key leading proposals for system intervention are responsive to problematic location. The various recommended interventions (e.g. promising solutions to some of these systemic problems) are developed from emerging models of diagnostic practice for improving cancer outcomes in Canadian provinces and territories, as well as established best practices currently used in other countries than Canada.
Both maps show the stage of the cancer lifecycle referred to as suspicion to diagnosis. This diagnostic interval is recognized as the period between a patient’s presentation of concerns to receiving a confirmed diagnosis from a cancer specialist, up to the point of entering subsequent treatment for that diagnosis. Both maps clearly indicate the point of transition to cancer treatment for the pathways.
