Thank you.
I provided a briefing document in both English and French that will elaborate in more detail the concepts I'd like to cover in my brief discussion today.
I was given a number of topics that I was told were of interest to this committee. I chose three to give my point of view on.
If you look at page 3 of the document, there are three questions I attempt to answer here. One is why is health care so slow or behind in adopting information technology approaches that have been adopted in other industries and derive benefits? The second question is a brief overview of what we're doing at the Ottawa Hospital to address that very challenge. Then I make a few comments on my thoughts on how investments may be redirected as we go forward with new challenges that are emerging.
I will give you a brief bit of context. I think there's a story behind this that will set the foundation and make the points of view I'll bring forward more interesting.
Twenty-five to 30 years ago, hospitals were almost 100% people-driven in terms of the activities, and almost 100% paper-driven in terms of information flow. That was also true of most other industries, such as manufacturing and banking. At that stage, things were status quo. That period of the 1970s I would say was the point of divergence in the creation of the concept of health care being behind in terms of information technology.
If you flip to page 4, what I'd like to do is go through a brief history of how hospitals and the health system evolved, because I think it's important that we all have that. It's based on facts. It's not my opinion whatsoever.
In the early, early days, medicine was general practitioners in rural communities, and they would go to a home and deliver care. It was a small business model. That would be the late 1800s. As we got into the 1900s with the phenomena of wars, urbanization, and so on, institutions were created called hospitals, but hospitals were staffed and managed by nurses, and they were meant for people who needed constant care. Primary care was still delivered in the home environment. That persisted through until I would say the 1930s and 1940s.
World War II may be the catalyst, but in any case there were two factors that led to increased complexity. One of them was advancement in medical technologies and approaches. We only have radiologists because we invented a machine called an X-ray that needed interpretation so it created a new medical specialty; dialysis created nephrologists; and gas machines created anesthesiologists. The combination of the medical specialties and the medical technologies, which were both quite expensive and scarce, caused us to consolidate those in a thing we called the hospital. The hospital began to transform in terms of what it did. It actually delivered proactive care leading to health or recovery, and then people would go back to their home.
The other phenomenon that perpetuated was a high degree of referral now between general practitioners or physicians in the community to the hospital for an X-ray, for a laboratory investigation, or some other specialty consultation. The referral between primary care and the hospitals happened in the 1940s and 1950s.
Then what happened through the 1960s and 1970s is that hospitals began to reorganize themselves, because as this advancement in medical technologies and medical specializations and treatment approaches evolved, there became a hierarchy of hospitals, which persists today. There are rural hospitals, community hospitals, acute centres, and then teaching and academic centres. That's roughly the hierarchy we live with today.
In the meantime, we introduced information technology starting in the 1970s, but really through the 1980s and 1990s. We approached it so that each institution had its own information system, and that was quite fine, because the interaction was of low complexity. People could share documents through paper. It worked well.
What's happened to bring us to date is that the complexity of interaction between the hospitals—people's movement and their health information flow—is much, much more complex and much more timely. That is what has brought us to the current state.
In terms of the vendors supporting the systems, they were able to tackle what are called ancillary departments—laboratory, medicine, and medical imaging—because they are highly standardized. Whether it's here or in Toronto, we do our work the same way.
In the medical areas, the treatment areas, there's a high degree of variability in terms of how a particular process is carried out. You can have the same treatment at the Ottawa Hospital on three different occasions and you'll have three different experiences—not outcomes necessarily, but three experiences—because it's a human-driven process, even though we've made it largely electronic.
I hope that sets out a platform that makes sense.
On page six of the briefing document, you'll notice “figure 1”. If you'll allow me, I'll use that as a framework to explain a few concepts that I think are important.
If you go from the bottom to the top—this equates to approaches taken in other industries—the basic step you need to do is eliminate variability and variation where you can: standardized processes where it's possible. These are the first and second steps.
Once you've done that, you have a chance to use approaches, such as Lean or Six Sigma, or other approaches, to optimize how you do your work. How the work is done at one end of the hospital is exactly the same as it is done at the other end, at some level. Then you get up into behavioural, organizational, and cultural change challenges; performance measurement and performance management; and then managing processes. The ultimate goal is to proactively manage your resources across the hospital in a predictive way.
We've tended to attack the middle of that model. We've done a lot of work. You've heard a lot of talk about Lean, patient-centred care, physician and staff engagement—the topics on the right-hand side. We haven't paid much attention to the bottom two: eliminating variability in the processes in the hospital. Because of that, we haven't been able to effectively manage our processes or resources in the hospital.
The approach we're taking at the Ottawa Hospital, and I guess my basis of recommendation.... On slide 8 you'll see another figure. The “current state” is an explanation of what basically goes on in the health system, not just in hospitals. You have many care providers at the top level, and you have many disparate systems carrying information about each one of us as patients at the bottom level. The interaction between these is sporadic and not consistent.
We've tried to attach the systems together, and to some degree attach the people together at the top, but it's done in a way that's not sustainable. The approach we're taking at the Ottawa Hospital, through process standardization, is to use the processes as the mechanism or catalyst to bring the information out of whatever systems they reside in and push them up to the people who need to see the information in those systems. The process would dictate what information I would need to see as a physician, what information a nurse needs to see, and so on. That's the basic concept.
