The goal of CCM is to implement a guideline-driven, evidence-informed approach to delivering care so as to improve the quality, safety and consistency of key clinical services and to improve patient experiences of care. [...] As summarized in Table 1 below, the properties of complex systems include: the nonlinear and random nature of many relationships within the system; the number and nature of feedback loops within the sys- tem; the interconnectedness of risk factors, environmental conditions and policy/practice interventions; the heterogeneity of individuals; and the capacity of the system for adaptation and self-or [...] The results fed into the first iteration of framework diagrams and helped refine the questions for the key informant interviews. [...] Focus groups The purpose of the focus group sessions was to test key themes derived from the KIIs and to learn about the impact of local context on large-scale change, and in particular on guideline implementation. [...] The online validation survey was used to confirm the study’s findings and to get broader buy-in and understanding of the work being done.
