Health care systems across the world are in a state of flux. If the experience of the early 1990s can be used as a model, the recent global economic downturn will lead to very significant pressures to reduce spending and achieve better value. Systems have provided a range of approaches to modeling and evaluating these more complex organizations, from simple process models to complex adaptive systems. This paper considers the pros and cons of such approaches and proposes a new modeling approach that combines the best elements of other techniques. This paper also describes a case study, where the approach has been deployed by the authors. The case study comes from health care services in Ontario, Canada, who are shifting from the traditionally hospital-based system to one that recognizes a greater role for community and primary care services.

Actor Networks

The trend toward convergence, initiated by advances in ICT, entails the creation of new value chain networks, made up by partnerships between actors in unrelated industries. Such a process of convergence, however, can create a new dimension of network complexity, precipitating dynamic behavior among actors. In this paper we seek to understand how different actors in value chain networks have co-evolved in practice with the development of convergence services. Interpretative case studies on two different converged services in Korea (mobile banking, and One phone services) are undertaken to examine how different actor network adapted in different ways to shape the overall complexity of the converged service. The case study analysis is innovative in being conducted within a combined framework of Complex Adaptive Systems and Actor Network Theory. This synthesis offers a way to characterize the drivers of co-evolutionary behavior, capturing the translation processes undergone by actor networks.

Abstract Background To meet the complex needs of healthcare delivery, the Ministry of Health and Long Term Care (MOHLTC) introduced Physician Assistants (PAs) into the Ontario health care system in 2006 to help increase access to care, decrease wait times, and improve continuity of care. Integration of new health professional roles is often stymied by role resistance and funding barriers. The characterization of healthcare organizations as complex adaptive systems (CAS) may offer insight into the relationships and interactions that optimize and restrict successful PA integration. The aim of this study is to explore the integration of PAs across multiple case settings and to understand the role of PAs within complex adaptive systems.Methods An exploratory, multiple-case study was used to examine PA role integration in four settings: family medicine, emergency, general surgery, and inpatient medicine. Interviews were conducted with 46 healthcare providers and administrators across 13 hospitals and 6 family medicine clinics in Ontario, Canada. Analysis was conducted in three phases: inductive thematic analysis within each of the four cases; a cross-case thematic analysis; and a broader exploration of cross-case patterns pertaining to specific complexity theory principles of interest.Results Support for PA contributions across various health care settings, the importance of role awareness, supervisory relationship attributes, and role vulnerability (in relation to sustainability and funding) are interconnected and dynamic in hospital and community settings. Findings represent the experiences of PAs and other healthcare providers, and demonstrate how the PA’s willingness to work and ability to build relationships within existing health systems allows for the establishment of interprofessional, collaborative, and person-centered care. As a self-organizing agent in complex adaptive systems (i.e. health organizations), PA role exploration revealed patterns of team behavior, non-linear interconnections, open relationships, dynamic systems, and the legacy of role implementation as defined by complexity theory.Conclusions By exploring the role of PAs across multiple sites, the complexity theory lens concurrently fosters an awareness of emerging patterns, relationships and non-linear interactions within the defined context of the Ontario healthcare system. By establishing collaborative, interprofessional care models in community and hospital settings, PAs are making a significant contribution to Ontario healthcare settings.

AbstractDuring interactions, system actors may face up misunderstandings when their local states contain inconsistent data about the same fact. Misunderstandings in interactions are likely to reduce interactivity performances (deviation or deadlock) or even affect overall system behavior. In this paper, we characterize misunderstandings in interactions between system actors (that may be human users or system agents) in interactive adaptive systems. To deal with such misunderstandings and ensure state consistency, we present an agent-based architecture and a scenario structuring approach. The system includes several agents devoted to scenario unfolding, plot adaptation and consistency management. Scenario structuring is based on the notion of a situation that is an elementary building block dividing the interactions between systems’ actors into contextual scenes. This pattern supports not only scenario execution but consistency management as well. In order to organize and control interactions, the situation contextualizes interactions and activity of the system’s actors. It also includes prevention and tolerance agent-based mechanisms to deal with the misunderstandings and their causes. We validate our consistency management mechanisms using Uppaal simulation and provide some experimental results to show the effectiveness of our approach on an online distance learning case study
