Conceptual Modeling of the Healthcare Ecosystem
Eng. Andrei Vasilateanu
Slide2Overview
Challenges
faced by healthcare systems
New paradigms in healthcare
Conceptual modeling and system engineering
Digital Healthcare Ecosystem (DHE)
Conceptual model of the DHE
Slide3Challenges in healthcare
Increasing expenses, low quality of medical services
Slide4Causes
Structural changes in the population:
By 2050
number of older people in less developed countries is projected to more than quadruple (from 374 million in 2000 to 1570 million)
proportion of very old people (over 80 years old) will constitute 10% of the population in Europe as opposed to only 3% today.
results in increasing pressures on the healthcare system
Slide5Changes in disease prevalence: chronic vs acuteHealthcare systems designed to treat acute diseases
Today most deaths caused by chronic diseases
Slide6New paradigms in healthcare
Changing the role of the patient -> first-class actor in his healthcare process
Patient empowerment : educated patient, able to make informed decisions
Continuity of care: informational, management, relational continuity
Team care: multidisciplinary and cross-organizational
Slide7E-health
an emerging field in the intersection of medical informatics, public health and business, referring to health services and information delivered or enhanced through the Internet and related technologies.
In a broader sense, the term characterizes not only a technical development, but also a
state of the mind
, a
way of thinking
, an
attitude
, and a
commitment for networked, global thinking
to improve Health-care locally, regionally, and worldwide by using information and communication technology.

Slide9Models in System Engineering
Model = semantically closed abstraction of a subject system
Model purposes:
Visualize and communicate to others a system
Specify the structure and behavior of a system
Give a template for constructing
a system
Document
the design decisions
Slide10Model Driven Architecture
Software development process
Architecture = specification of the components and connectors of the system and the constraints and rules for the interactions between the components
Defines what models to be used and their relationship, creates 3 viewpoints:
Computation independent viewpoint
Platform independent viewpoint
Platform specific viewpoint
Slide11Digital Ecosystems
Natural life ecosystem
= a biological community of interacting organisms plus their physical
environment
Digital species
Digital

sectors of the Digital Ecosystem (telecommunications, media and IT industries):
“
Ecosystem
players
could spend more effort in identifying the next areas of welfare creation that can be targeted in all sectors of the economy, thus generating additional value for the industry to share in. Sectors such as healthcare, logistics
, transportation, financial services, education, and retail are all likely to present significant opportunities to leading companies within the digital ecosystem in the coming years. Indeed, shifting focus away from competing within their existing boundaries to solving pressing social and business problems in these sectors may afford participants in the TC, ME and IT industries opportunities to collaborate and grow their collective and individual profit pools.” (Michele Luzi and Jennifer Binder-Le Pape: EMERGING “DIGITAL ECOSYSTEM BUSINESS MODELS AT THE CONFLUENCE OF THE IT, TELECOM, AND MEDIA AND ENTERTAINMENT INDUSTRIES”, GOVERNORS MEETING FOR THE DIGITAL ECOSYSTEM)The Digital Ecosystem is the space formed by the convergence of the media, telecoms and IT industries. It consists of users, companies, governments and civil society, as well as the infrastructure that enables digital interactions.
Slide12Ecosystem Characteristics
One of the most important features of biosystems is how they are able to maintain local order (low entropy) within their system boundaries.
Ecosystems grow and develop in four progressive growth forms reflected in: boundary, structure, network, and information relationships.
Slide13Digital species:
autonomous, proactive and adaptive entities
Organized in digital communities
Peer to peer interactions through information flows
Existing digital components can be equipped with digital organs to function in the DE
Slide14Digital ecosystems are “the dynamic and synergetic complex of Digital Communities consisting of interconnected, interrelated and interdependent Digital Species situated in a Digital Environment, that interact as a functional unit and are linked together through actions, information and transaction flows.”
Slide15Virtualization of the Business Ecosystem
Slide16Digital Healthcare Ecosystem
Slide17Reflection of the healthcare ecosystem
Slide18Modeling the health state
Health state = mental representation or abstract object
Reflection in our digital system of the real state of the patient
Tends to minimize the gap between reality and representation by accumulation of observations
Slide19Layers of abstraction
Health issue, health condition, health state
