Interoperability still faces many hurdles, study
By Jerry Zeidenberg
TORONTO – It’s often said that the power of electronic health records
won’t be fully realized until healthcare providers in hospitals,
long-term care centres and clinics can all share the same electronic
charts. Only then will they get a full and accurate medical view of
Unfortunately, it appears there’s a long way to go before we reach that
state of electronic nirvana. Indeed, one out of every three hospitals in
Canada has trouble with interoperability of clinical systems within its
own walls – never mind connecting successfully to outside providers,
according to a new study conducted by Canadian Healthcare Technology
In May, the magazine polled 300 chief information officers and IT
directors at hospitals across the country to find out about their level
of interoperability with providers outside and within their own
Of those invited to participate, 52 completed the entire questionnaire.
A third of the respondents (33 percent) said they’re having trouble with
interoperability of clinical systems within their own hospitals.
According to one respondent, “[We have] multiple applications, developed
separately, by different vendors, with limited ability to integrate with
That’s been a common complaint heard anecdotally at industry conferences
and informal meetings, but we believe the Canadian Healthcare Technology
survey is one of the first instances of a formal poll showing the extent
of the challenge across the country.
The study, titled The Communication Gap: Problems and Plans for
Interoperable Systems in Canadian Hospitals, covers the following
• the state of clinical interoperability within hospitals and with
outside hospital organizations;
• clinical interoperability among hospitals, long-term care centres and
• barriers to interoperability and connectivity;
• usage of various standards in hospitals;
• wireless use in hospitals today and plans for the near future;
• views of CIOs and IT directors on whether provincial eHealth programs
are useful – or not;
• IT investment plans.
The full report, with tables and analysis, will be published by Canadian
Healthcare Technology this fall.
To produce the interoperability survey, significant issues were first
determined through telephone interviews and e-mail conversations with
five hospital CIOs in different parts of the country, and with several
What’s the cause of the interoperability troubles in hospitals? For 17.5
percent of the CIOs and IT directors, the problem stems from
incompatible software; 15.9 percent blamed incompatible communication
systems; 17.5 percent identified improper governance and consent systems
as the culprits; and 19 percent said all of the above.
Long-term care: As a solution for improving patient flow in hospitals,
it’s generally agreed that faster, more efficient placement in long-term
care centres is needed. To do this, better communication among
hospitals, nursing homes and other long-term care facilities would help.
(Indeed, 81 percent of the CIOs and IT directors agreed that electronic
communications with long-term care centres would improve patient flow.)
However, nearly 62 percent of our respondents told us their hospitals
don’t communicate regularly with long-term care centres using electronic
systems. What does this mean? Too often, the movement of patients is
slowed down by the inefficient collection and transmission of data.
Hospital staff often spend time waiting or searching for paper forms,
then manually create new documents and fax them from one organization to
the next. It could be so much faster and smoother if the process was
done electronically using compatible software.
Interestingly, while a third of the respondents intend to connect
electronically to long-term care centres in the next two years, another
third have no plans do so.
In fairness, as one of our CIOs pointed out, the benefits of connecting
hospitals with continuing care centres have been demonstrated, but
long-term care facilities themselves must also be willing to participate
– something that not all of them have desired to do. They, too, must
become more proactive about establishing clinical networks.
Physician practices: We were surprised to see that a vast majority of
hospitals – nearly 80 percent – have connected electronically with
physician clinics. Our assumption was that not much progress had been
made on this front – happily, this was shown not to be the case. The CIO
and IT directors noted a high degree of activity, with much more planned
for the future. They’re connecting with doctors via portals and remote
access, and sometimes through a mixture of both.
Standards: When we asked about various standards used in hospitals,
there were some real surprises. For example, no hospital reported
extensive use of Integrating the Healthcare Enterprise (IHE) profiles –
despite the zealous work of organizations like HIMSS and the RSNA to
promote IHE over the past 10 years. Indeed, one respondent even asked,
‘What is IHE?’
On another front, LOINC has been identified as a key standard for
integrating lab systems. But only 16.7 percent of hospitals report they
use LOINC to a great extent.
Certain standards have made inroads, however. HL7 v2, for example, is
extensively used in 64 percent of the hospitals, while DICOM is also
entrenched in 64 percent. While that’s a substantial number, one might
wonder why these well-known standards aren’t even more extensively used.
Politics: Much of what’s done in healthcare I.T. is made possible only
through funding, and a good portion of the manna has been dropped on
hospitals by government programs. On this note, we asked our CIOs and IT
directors whether the eHealth scandals of the last year have taken a
toll on IT projects at their hospitals.
In response, over a quarter of them (26.9 percent) said the eHealth
embarrassments have had an impact on them. Fifteen percent said it will
take two to three years for their budgets to recover, while another 8.5
percent said it will take three years or more.
Asked if they thought their provincial governments had an ability to
create an effective eHealth strategy, 42 percent of the respondents said
not at all; 52 percent said their governments had ‘a moderate ability’;
and only 6 percent checked off the ‘excellent ability’ category. So much
for confidence in the government designers of a modern healthcare
Ontario’s eCHN shows that integration and
interoperability are possible
By Andy Shaw
First lesson: integration and interoperability are not the same. The
words are not synonymous; though we often use them interchangeably,
which adds to the confusion. But like love and marriage, they do go
together like a horse and carriage. So, any attempt to “integrate” your
systems, meaning by definition combine them into one, unified whole –
without your systems being able to “interoperate”, meaning exchange and
make use of their information, will inevitably end up in divorce.
Of course, the ones that suffer most in a divorce are usually the
children. So maybe it’s only fitting that those who have done the best
job so far in healthcare of marrying integration with interoperability
are those who care for sick kids. None better, nor longer, than the
dedicated folks at Ontario’s eCHN, the electronic Child Health Network.
Since its inception more than 10 years ago, eCHN staff have been
integrating with the rest of the province’s healthcare organizations and
making their patient information systems interoperable – such that
nearly 1.8 million of Ontario’s children now have an eCHN electronic
paediatric health record. Those records can now be shared electronically
Ontario-wide, thanks to eCHN.
Among eCHN’s other accomplishments and features:
• integrates child care data from disparate systems – including over 100
hospitals and tertiary care providers, such as children’s treatment
centres, community health centres, and physicians offices – into one
• enables family physicians to refer and follow up on a child’s visit to
a paediatric specialist;
• gives members access to a suite of paediatric care applications on the
• maintains and staffs its own round-the-clock, high availability data
• operates a technical and user support help desk.
It’s clear that eCHN has more than a child-like grasp on integration and
interoperability. That’s very much because, from the top down, they
understand the difference in the terms.
“First, we define integration as the creation of links between
previously separate computer systems, applications, services or
processes,” says eCHN’s chief executive officer, Andrew Szende. “As to
interoperability, that’s not about making each separate resource know
how the others work but about making sure they have enough common ground
to reliably exchange messages without error or misunderstanding.”
Mr. Szende further adds that in defining the word integration: “…the
word is normally used in the context of computing, but can apply to
business processes as much as to the underlying process automation. In
the past, computer integration – for example in enterprise application
integration (EAI) – has typically been tightly coupled, or ‘hardwired’,
making it difficult to modify in response to changing requirements. But
thanks to the advent of web services and the evolution of
service-oriented architectures, more agile, loosely coupled forms of
integration are now starting to emerge.”
So in this modern “loosely coupled” era, who or what is going to
exercise the tight discipline still needed to make sure one’s disparate
systems dutifully and reliably establish common ground – so they can
indeed exchange messages without fault?
Says Szende: “Standardized specifications go a long way towards creating
this common ground where services can interact, but differences in
implementation may still lead to breakdowns in communication.”
And in Ontario, they know about breakdowns! Indeed, the scandals
surrounding the province’s eHealth initiatives got so heated last year
there were meltdowns of entire agencies and programs aimed at both
integration and interoperability.
But eCHN cooly withstood the heat. And it wasn’t the first hurdle they’d
cleared in building their enviable network.
“As an organization our first obstacle to overcome was integration with
Ontario’s hospitals. And as most of your readers will know, Ontario’s
hospitals have dozens of different clinical information systems that
collect data and store them in unique, site specific ways,” says Szende.
“So eCHN built interfaces to the various vendor-provided applications
and conducted detailed site specific surveys in order to successfully
integrate both the data and its specific business rules into the eCHN
Still, hospitals are no peas in a pod. Integration with their
idiosyncratic, and often proudly held onto systems is both a technical
and human challenge. One that’s defied many an integrator, but not eCHN.
“Every hospital site had some degree of customization applied on top of
the vendor-provided applications. These customizations had to be
understood by the eCHN team, integrated and normalized in order to allow
clinicians to view the data in a consistent manner,” says Szende. “And
we admit that wasn’t easy. So for our integration efforts we used an
experienced data team that had a clinical background that could interact
with domain experts at the hospital sites as well as with the clinical
That doesn’t mean eCHN is resting on its laurels, adds Szende quickly.
“Our integration effort is really a continuous one. We keep pace with
member hospitals who are upgrading and updating their internal systems
so we can always communicate with them in real time.”
Well and good, but how do Szende and eCHN know for sure they’re doing a
the right things?
“We judge it by the enthusiastic feedback we get from our members, and
most of all from clinicians,” says Szende. “They say they can rely on
us, and I think that is the key to successful integration. Clinicians
will not use systems that contain obsolete or error prone data.”
Another indicator of eCHN’s success is public recognition. Recently, the
Hospital for Sick Children in Toronto won a “WOW Award” as Canada’s
smartest IT application user in healthcare for its role in helping to
develop the eCHN and being an early adopter.
Thus, endeth the first lesson.
Second lesson: Others can do the same. Take, for example, the
provincially funded Children’s Treatment Network of Simcoe York,
launched in 2004 and now stretching from the north end of Toronto all
the way up to Georgian Bay. It has developed an “Electronic Client
Record” that reaches beyond healthcare providers and integrates the
electronic records of nearly 4,000 children and young people up to age
18 with the systems of over 600 children’s care workers in related
fields including educational and social services.
“We sprang from the straits families found themselves in with children
who needed complex care,” said Sandy Thurston, a Network founder and now
the director of its planning, evaluation, and network development, at a
recent show-and-tell LHIN conference in Toronto. “They needed services
from such a fragmented and distant array of care providers that the
parents, in addition to their own jobs, had another nearly full-time job
of being their children’s case managers.”
Moving from that need, through a vision that won the support of over 50
information sharing partners, the Network now has four main features:
1. A single point of access to the care system for families with
children suffering from diseases like cancer, and others requiring
2. Ten integrated care teams of medical and other specialists available
3. A “single plan of care” for each child that integrates not just their
healthcare support system but their community, social, school, and even
4. An assemblage of a wide range of other child care specialists who
could be called on to collaborate with Network care teams.
As a basis for all the collaboration it has engendered, the Children’s
Treatment Network is using Microsoft’s SharePoint application. The
Network also uses SharePoint for its Family Resource Centre, an internet
portal which parents and computer savvy patients can access to share
their knowledge and experience with other families and patients.
“We believe, judging from the feedback we get, that we provide as much
value for patients out of the Family Resource Centre as we do from our
formal care,” said Thurston.
While the Children’s Treatment Network is exemplifying community-wide
integration, the electronic Children’s Health Network is sorting out
which comes first: the chicken or the egg. Or rather, the fundamental
question of how should integration and interoperability relate to each
other? Which, in effect, should come first to your attention if you want
the marriage of the two to really work?
“Originally, eCHN’s priority was integration. Now interoperability is
equally important,” says CEO Szende. “We make eCHN conform to blueprints
and strategies, so it can operate with other solutions. To do that we
support data exchange conforming to Canada Health Infoway (CHI)
preferred information access methods, such as webMethods and the
publish/subscribe model that are part of the CHI Blueprint.
“Our team took that approach because we wanted to be compliant with the
Blueprint’s electronic health record (EHR) principles,” adds Szende. “We
also implemented a service-oriented architecture that makes it easier to
interoperate with provincial services and products as they become
“As a result, eCHN is currently a flexible, open, scalable and
interoperable EHR solution. So if and when the Ontario Laboratory
Information System (OLIS) goes live, for example, we’ll be able to
interoperate with them and exchange OLIS lab results. We’re also looking
forward to hooking up with other provincial services, such as patient
and provider registries, when they become available.”
Lesson three: you can do it too. And you don’t have to do it all by
yourselves. Not only do you have the shining examples of the eCHN and
the Children’s Treatment Network before you, there’s money out there, or
at least the promise of it. And not just from provincial coffers.
Lean approach scores high marks in trial at the
University of Ottawa Heart Institute
By Rosie Lombardi
Lean is a concept that’s floating around in hospital circles, but
there’s a lot of uncertainty about what it means exactly or how
disruptive it may be.
“I’d heard comments about it and people seem to have some trepidation
about it,” says Timothy Zakutney, Manager of the Biomedical Engineering
Department at the University of Ottawa Heart Institute (UOHI). “But the
more I learned about it, the more fascinated I became to try it.”
To evaluate Lean’s benefits, Zakutney made a convincing case to hospital
executives to have his area serve as a test-bed for the potential
implementation of Lean throughout the UOHI.
Although he has a high-functioning team of eight staff dedicated to
maintaining and repairing VADs, heart lung systems, echocardiography,
ventilators and other technology, he says there was room for
improvement. “Engineers are pack rats, and the area was getting
cluttered with tools, parts and equipment. We needed to make the
workspace more efficient to help us focus on tasks from initiation to
Infection control is another issue that is gaining more urgency in
hospitals. “Not having an orderly, tidy workspace makes infection
control challenging. I wanted to make it a safer environment for staff.”
The central question he asked staff to consider in rethinking their
processes was: What minimal tools are needed to get the job done based
on the urgency, frequency and severity of tasks?
The team then moved into the next phase, working with GE Healthcare Lean
workflow specialists to develop solutions. “There was a lot of data
gathering and observation of staff by GE Healthcare to analyze existing
performance, in addition to spaghetti diagramming and process
Simulating processes with the help of an external facilitator applies
Lean thinking and gets staff to take an objective look at what they do,
says Michčle de Montigny, a GE Healthcare consultant who worked with the
UOHI team. “We go through simulations and ask staff: Show me how you
would repair a ventilator. Walk me through the steps. Lay out the tools
and parts you need.”
Zakutney says this part can be emotionally challenging, but is one of
the most valuable aspects of Lean in helping staff optimize their work
areas. “It’s about exposing the way you work and opening yourself up to
new and better ways to get work done. People react differently to this,
which is why Lean is ultimately about changing human behaviour. Having
external experts to help you through is useful, and GE Healthcare is
great at recognizing at what level people are in this emotional roller
During the implementation phase, the team worked hard to clean-up, sort
and standardize, all within the period of one week. “We went through
every desk, nook and cranny and sorted all the components. Then we
literally scrubbed everything down with the help of housekeeping, and
put back only the needed tools and equipment in a standardized order. ”
The final and most important phase of the Lean effort was the
sustainability piece, says Zakutney. “After we put everything in order,
we started implementing checklists, so that going forward, we would
maintain everything we had accomplished.”
The consensus-building that’s part of the Lean approach was hugely
important. “The big thing for me as the manager is that the staff took
on the responsibility of decision-making. This engaged them in the
process and facilitated the success of the project.”
The project was completed in May 2010. While Zakutney says he plans to
collect and analyze six months of data to determine the measurable
benefits, there are already some clear improvements that he has
observed. “People have a greater feeling of control over their workload,
and they’re working smarter because they’re spending less time searching
The VP of Finance at the UOHI was supportive throughout the project, and
was pleased with the results and sense of pride it fostered in staff.
“So we’re going on the Lean journey and will be moving forward with
applying Lean in our diagnostic imaging area,” say Zakutney. “And we’re
exploring implementation in our clinical services, our discharge
management processes, and on our nursing units.”
Bayshore the first home care organization to
transmit HOBIC data
By Leigh Popov
In April of this year, Bayshore Home Health became the first home care
organization to electronically transmit patient-centered, evidence-based
clinical health data to Ontario’s Health Outcomes for Better Information
and Care (HOBIC) initiative.
According to the Ontario government, “The ability to collect and produce
more accurate and comprehensive information and make it available for
decision-making is essential to the transformation of our health system.
This information will help us understand the impact of nursing and other
disciplines on a patient’s health.”
HOBIC’s mandate is to implement Ontario-wide, standardized collection of
patient health outcomes, staffing and quality of work life information
reflecting a variety of disciplines, including nursing.
HOBIC provides valid, reliable information that is patient-centred,
evidence based, outcome-focused and comparable across all sectors. HOBIC
has already made significant inroads in the acute care sector, and has
seen good adoption in hospitals within the province.
We decided to engage with the HOBIC initiative because it made perfect
sense for our organization as we transition from traditional to
evidence-based clinical practices. Although HOBIC’s roots were in
Ontario, it has now become a national initiative. As a national nursing
organization, Bayshore recognized the value of applying the same
evidence-based, outcome-focused principles of the HOBIC model across our
From a business standpoint it was a pragmatic choice. In aligning with
HOBIC we could leverage existing resources and research rather than
reinvent this body of knowledge ourselves, and in the process have to
redesign and redeploy our systems. In other words, we chose not to
reinvent the wheel.
Our progress: Our work on the HOBIC project started late fall 2009. The
first order was to make changes to our electronic forms to accommodate
HOBIC data elements. In doing so, we added certain fields and developed
a special assessment which our field nurses could fill out at the
community point of care.
Next came development of two interfaces: one from our clinical
management system to our middleware platform; a second from the
middleware to HOBIC directly. We believed using a three-tier
architecture option was a more efficient approach in this case, since
the technology was already in place and we could realize the added
benefit of repurposing the inbound clinical data to our own clinical
data repository as well as to HOBIC.
Interface development, testing and debugging, activation and training of
field staff continued through to March 2010, with rollout happening in
the second half of the month.
Bayshore Home Health nurses use a secure mobile electronic charting
application in the field. Nurses immediately started filling out the
assessments which were then automatically transferred to HOBIC. At the
same time, they were given access to the HOBIC database on the same
devices in the field for review, assessment and possible adjustment of
care plans to enable the best possible outcomes for clients.
Lessons learned: In achieving our goals, we worked with a number of
partners on both the implementation and development sides of the
initiative. These partners included vendors of clinical management
systems who assisted in the data extraction and adaptation for
electronic form delivery, interface development specialists who ensured
the successful execution through the middleware architecture, and
HOBIC’s technical solutions group who assisted with testing and
Data field mapping is a large component of interfacing and makes each
interface unique. This was certainly the case here, however, we were
still able to draw on the experience of others to help in this
For example, we looked at HOBIC’s numerous implementations in the acute
care sector and their technology partners as a resource for addressing
such fundamental issues and processes as communication protocols and
exception/error handling. Error handling specifically can be problematic
if working out for the first time. HOBIC’s experience here helped make
the troubleshooting and validation process run smoothly.
Results: For many organizations such as ours, a successful transition to
HOBIC does not require radical infrastructure change. At Bayshore, the
technology requirements were largely focused on the connection element,
as well as internal training, project management and perhaps most
importantly, change management support.
With the healthcare sector challenged by rising demand and costs, we
firmly believe that wide deployment and proper use of HOBIC will drive
costs down through improved outcomes. A more integrated model of care
can also reduce duplication not only in each vertical sector, but also
across sectors in the greater health system.
Although the Province is still in the early stages of database building,
the population and trending data gathered through HOBIC will prove
invaluable in supporting the healthcare system moving forward. The data
provided will also help organizations such as Bayshore expand
efficiencies throughout our nationwide system, regardless of location.
Having strong, measurable data provides a strong foundation for
effective evaluation and decision-making at the system, organizational
and client levels. We believe that taking these initial steps with HOBIC
today will bring us closer to the goal of quality, patient-centered,
