3Increased Emphasis on eHealth in Canada
Spending and Innovation
4Increased Emphasis on eHealth Spending in Canada
- Challenge - pull together the current IT silos or
paper systems that support 121B spending per
year for healthcare in Canada (85B Govt, 36B
Private) - (more than 10 of Canadian GDP)
5Canada Health Infoway (CHI 2005)
- CHI Federal Agency provides joint funding for
health infostructure projects. 1.2 B available
for capital investment - Business Plan 2005-06
- CHI provides 75 funding for eligible projects
- Collaborates with provincial health ministries
and private sector partners - By March 31, 2006, 646 million will be approved
for specific projects (54 of total available)
6CHI
- Primary focus is on supporting interoperable
health information systems with electronic health
records across Canada (for U.S.A. see Brailer
2005) - Estimated savings for a completed system would be
6.1 B annually - Target is to be supporting 50 of Canadian
population with such systems by 2010
7CHI Funding and Targets
- Client provider registries 110M
- Diagnostic imaging systems 220M
- Drug information systems 185M
- Lab information systems 150M
- Interoperable EHR systems 175M
- Telehealth 150M
- Public health surveillance 100M
- Innovation and adoption 60M
- Infostructure 25M
8Discussion
- Likelihood of IT project failure increases as
project size and scope increases - Need to focus on
- Involvement of all the stakeholders (governments,
private corporations, healthcare providers,
citizens) - Evolution if possible, revolution if necessary
- Standards, interoperability
- User acceptance
- Smaller projects that will link together to
support overall objectives - Major edge that CHI has is that its projects make
use of existing technologies. - Major handicaps
- Many stakeholders with differing agendas
- Huge differences in levels of IT sophistication
across the healthcare sector
9Business Process Modeling and Workflow Management
10Business Process Modeling
- Major tool for communication between developers
and users graphical, backed up with
documentation - Complete description of a business process needs
information - describing constituent business process
activities - resources assigned to activities, (objects
necessary for execution of activities, - actors,
documents, data and so on - controls of the business process - when and
which activity will be executed - flow of data in the process
- organizational structure - organizational units,
people, roles, competence etc. - Business process modeling approaches should
enable the modeling of all these types of
information - provide facilities for tracing, simulating and
graphically animating the constructed business
process models.
11Business Process Workflow Models
- A business process model is a process abstraction
that depends on the intended use of the model. - When such a model is intended for business
process implementation and automation, it is a
workflow model. - A business process model can be seen at two
levels at the reengineering level and at the
automation (implementation) level. Thus, the
model produced at the re-engineering level is
later transformed to another model at the
automation level in order to be used by
application development programs (e.g. WMS) or to
be directly executed in an existing working
environment.
12Business Process Redesign
- BPR closely related to major projects to
implement IT, including Enterprise Resource
Planning (ERP) systems, such as SAP, Oracle, etc. - But it should be used for every overhaul of
existing systems or implementation of new systems
13Process Innovation (Davenport 1993)
- Framework for process innovation
- Identifying processes for innovation
- Identifying change levers
- Developing process visions
- Understanding existing processes
- Designing and prototyping the new process
- Enablers of process change (change levers) can
include information technologies and/or changes
in organizational structure
14Failures of BPR (Bergey 1999)
- Contributing reasons for failures
- Adoption of a flawed BPR strategy
- Inappropriate use of consultants
- Workforce tied to old technologies
- Failure to invest in training
- Legacy system out of control
- IT architecture misaligned with BPR objectives
- Inflexible management team
- Lack of long-term commitment
15Success Factors in BPR (Paper 2005)
- Environmental success factors top management
support, risk disposition, organizational
learning, teaming, compensation and reward
systems, information sharing, and resources. - People success factors training, education,
politics resolution, ownership, and empowerment. - Methodology success factors appropriate guiding
principles, buy-in, direction, continuous
monitoring, graphical process map, and customer
support. - Technology perspective success factors IT
knowledge, IT belief system, and IT architecture. - Transformation or change vision success factors
vision development, vision communication, vision
deployment, and vision flexibility.
16Best Practices in BPR (Reijers 2005a)
- Eliminate unnecessary tasks from business
processes (i.e. those tasks that add no value
from the clients point of view) - Consider removing batch processing and periodic
activities from business processes (this may
speed up handling of specific tasks, but consider
that significant economies of scale may be
achieved for large transaction volumes) - Move controls towards the client (helps to
eliminate errors) - Consider integration of business processes with a
supplier (may apply, for example, to ordering
medical/surgical supplies) - Consider whether tasks may be executed in
parallel (may speed up execution substantially)
17Best Practices in BPR
- Design business processes for typical situations,
and isolate exceptions from normal workflows - Let workers perform as many steps as possible for
individual situations, providing that they have
the expertise to do so - Treat geographically dispersed resources as if
they were centralized (for example, through
better communications, specialist resource
expertise can be made available when and where
required, even if not physically present)
18Best Practices in BPR
- Avoid assignment of task responsibilities to
people from different functional units (this and
the following two best practices are the basic
idea behind service bundling approaches) - Consider assigning teams out of different
departmental workers to take care of complete
handling of specific work assignments. - Appoint one person as the case manager, with
responsibility for handling each work assignment - Consider making resources more specialized or
more generalized, depending on the particular
task classification. - Give workers most of the decision making
authority and reduce middle management (this
reduces the overhead and time spent on
authorizing work that has been done by others,
resulting in smoother operations)
19Fragment of Business Process Map
20Standards for Business Process Modeling (Graham
2005)
- UML (Unified Modeling Language) supported by
Object Management Group (OMG) consortium - XMI (XML metadata exchange) proposed by OMG
- BPEL (Business Process Execution Language)
supports automated application development
directly from business process models - BPMN (Business Process Modeling Notation)
provides a standard way to share process
information with business users, integration
developers, customers, business partners.
21Workflow Management
22Workflow Management
- Workflow Management
- The automation of a business process, in whole or
part - documents, information or tasks are passed from
one participant to another for action, according
to a set of procedural rules. - Business workflows can be well defined,
predictable, and frequently executed - structured
business workflows - Structured workflows can be automated by machines
to reduce clerical tasks and potential human
intervention errors - Workflow management systems (WMS) are systems to
facilitate automation of structured business
workflows.
23Sample Workflow Map (Mentzas 2001)
24Workflow Management (Reijers 2005b)
- Performance measures
- Lead time, i.e. the time between the arrival of a
case and its completion (also known as cycle
time, completion time, and turnaround time), - Service time, i.e. the time spent by resources on
the processing of a case, - Wait time, i.e. the time a case is idle during
its life cycle, - Utilization of involved human resources, i.e. the
ratio of activity versus their availability.
25Workflow Management Coalition
- Workflow Management Coalition
- Formed in 1995
- Over 300 member organizations worldwide
- http//www.wfmc.org/
- Develops recognized standards for WFM systems,
approaches - In the early 1990s, when WFM became a recognized
approach, it was suitable only for structured
workflows, resulting in many failures of WFM
systems because of a lack of flexibility - WFM has now evolved to become more flexible/
adaptable in handling workflows, including
exceptions. Also standards developed for XML
formats, etc. Still of most value to large
organizations with existing infrastructures of
systems like ERP, etc.
