Table 1
Integrated care concepts and definitions, based on Valentijn’s Rainbow Model taxonomy, used to inform study design and analysis.
| CONCEPT | DEFINITION (BASED ON VALENTIJN ET AL. [41]) |
|---|---|
| Principles of Integration | Underlying program philosophy, how the target population is defined, and reasoning or purpose of the program or initiative. |
| Breadth of Integration (Vertical vs Horizontal) | Vertical integration is rooted in a disease-focussed paradigm where care is escalated from generalists to specialists. Horizontal integration is rooted in a primary care and public health paradigm with an emphasis on ongoing, holistic and preventative health services. |
| Degree (or extent) of Integration | Expressed as a scale from segregation (no integration), linkage (low-level integration, connections and referrals), coordination (medium-level integration, active coordination of professions and organizations) to full integration (team-based care with pooled resources and shared management). |
| Clinical Integration (Micro-level) | Case management and polices to identify clients with specific risk profiles, care processes that ensure continuity, interactions between the provider and the client and the use of individualized multidisciplinary care plans. |
| Professional Integration (Meso-level) | Interprofessional education with a focus on collaboration; service delivery agreements between providers; and value creation for the professional. |
| Organizational Integration (Meso-level) | Governance structures amongst the organizations involved. Mechanisms for joint accountability and policies, having an explicit organizational strategy and the degree of openness and trust between organizations. |
| System Integration (Macro-level) | Alignment of regulatory frameworks, market dynamics and political and social climate to support integrated care. |
| Functional Enablers | Learning infrastructure for joint research and development; aligned information management, information sharing and benchmarking; and regular feedback on performance to enable quality improvement. |
| Normative Enablers | Having a shared long-term vision, the extent to which agreements are fulfilled, how reliable and predictable the behaviour of different team members is, strong leadership that mobilizes towards a shared vision, and linking cultures and values within the model. |
