Hamilton researchers discover a simple blood test could save lives after surgery

Researchers at Hamilton Health Sciences’ Population Health Research Institute (PHRI) and McMaster University have determined that a simple blood test can predict and possibly prevent many of the deaths that occur after surgery.

“If death after surgery within the first 30 days was made its own category of death, it would be in the top 5 leading causes of death within North America,” explained Dr. P.J. Devereaux, principal investigator for the “VISION” study.

The VISION study enrolled nearly 22,000 patients aged 45 years or older from 23 hospitals in 13 countries and found that approximately 18 per cent of them sustained heart damage within 30 days of non-cardiac surgery and that, without enhanced monitoring, the vast majority – as many as 93 per cent – of these complications will go undetected, potentially until it’s too late to intervene.

Putting pressure on the heart

“The effects of surgery anywhere in the body create a perfect milieu for damage to heart tissue, including bleeding, blood clot formation, and long periods of inflammation,” says Dr. Devereaux, scientific leader of perioperative medicine at PHRI, director, division of cardiology at McMaster University. “In most cases, this damage occurs within the first 24 to 36 hours after surgery when patients usually receive narcotic painkillers that can mask symptoms of cardiac distress.”

“These discoveries have the potential to save lives.”

After surgery, study patients had a blood test for a protein called high-sensitivity troponin T, which is released into the bloodstream when injury to the heart occurs. Devereaux and his team discovered that patients with troponin T levels beyond a certain threshold had increased risk of death within 30 days of having surgery.

Overall, the study found that 1.4 per cent of patients died within 30 days following non-cardiac surgery.

“One per cent seems like a small number, until you consider that about 200 million surgeries are performed each year around the world,” says Devereaux. “Where we’re letting patients down is in post-operative management. We now know that we need to become more involved in care and monitoring after surgery to ensure that patients at risk have the best chance for a good recovery. These discoveries have the potential to save lives.”

The results of the VISION study were published in The Journal of the American Medical Association.

Meet Gretta

While parked at the local Home Depot, Gretta Hutton received her diagnosis over the phone: it was Mantle Cell Lymphoma, she had 2 – 5 years to live, and there was no treatment offered beyond the standard of care treatment. After weeks of feeling hopeless, Gretta found a clinical trial at Hamilton Health Sciences led by Dr. Tom Kouroukis. A year later, Gretta’s cancer was in full remission.

Can you tell us a bit about yourself and your health story?

By day, I am a social worker in the health sector, counselling clients who are struggling with critial illnesses. In 2014, I began to feel ill myself and went to see my doctor for some tests. Driving home from work one evening, I received a call from my internist wanting to share the results. He asked that I pull over so I drove into the parking lot of my local Home Depot where he then gave the diagnosis: stage 4 Mantle Cell Lymphoma. A subsequent meeting with a local oncologist revealed that I had 2 – 5 years to live. More than that, I wasn’t given any alternative treatment beyond the standard of care, RCHOP, that might  help me beat my cancer. But thanks to the persistence of my friend and my sister, I discovered a clinical trial led by Dr. Tom Kouroukis at the Juravinski Cancer Centre at Hamilton Health Sciences (HHS). The care that I am receiving in that trial is outstanding. Dr. Kouroukis listened to me, not just as a patient, but as a person, and walked me through the science of the trial and my care plan.

Why does health research matter to you?

If you asked me two years ago whether I thought I’d be back at work and able to resume my normal activities, I don’t think I would have believed you. This place, and the research here, has saved my life.

I was very ill at the beginning of the research study—sleeping a lot, exhausted—but that started easing up within the first two months. After 12 weeks, I was feeling “normal”. When I didn’t dare to hope that I would beat my cancer, the research team was there, bringing my hope to life with the data and the results from the study. Now here I am, and I have my life back.

Health research, and the clinical trials that result from it, are really important because they offer patients a different path. Having options, especially when you’re ill, is really important.

How does health research contribute to a healthier Ontario?

Clinical trials don’t exist in a vacuum; they are the results of a whole body of scientific study. They move research discoveries into new and better therapies for patients like me. Without health research, you can’t have clinical trials, and without clinical trials, you can’t improve the health of Ontarians.

How can patients and families support, improve or empower health research?

One of the hesitations that people might have in participating in clinical trials is the safety aspect of it. The best people to help reduce fear, hesitation or, in some cases, stigma are the people who have gone through clinical trials. Those of us who have thought through the risks and the benefits, who have worked with the researchers and staff, and who have come out on the other side with renewed hope—we are the ones who need to share our stories with the public and be strong champions for health research.

Patients and the public also have an important opportunity to voice their health research needs to decision makers. If there are life-saving clinical trials and medicines available, then patients should be aware and have access to them. In my role as Ontario Lay Representative on the Canadian Cancer Clinical Trials Network since November 2015, I am working hard to ensure that that conversation takes place at the point of diagnosis for every patient with cancer or other serious illness even if their local hospital is not a research hospital in a major urban centre. Where you live should not be the determining factor in being offered access to research.

Our health system, including research and clinical trials, is a public system, and so the public itself can be a voice of change.

Towards a Wealthier City: Impactful, Innovative Health Research at St. Joseph’s Healthcare Hamilton

By Dr. Jack Gauldie, Vice-President Research, St. Joseph’s Healthcare Hamilton

With a strong history of medical leadership and a legacy of transforming patient care around the world, Hamilton hospitals are transforming the city through innovation, research and scientific discovery.

St. Joseph’s Healthcare Hamilton was founded in 1890 with a promise and vision to provide compassionate patient care to those who need it most. Since that time, our hospital and research enterprise has evolved to not only make our province healthier and smarter, but also wealthier.

Our affiliation with McMaster University and close relationship with Hamilton Health Sciences has created opportunity for our research to impact the city as a whole through collaborative research that produces innovative diagnostics, treatments and medication. For examples of this kind of impact, watch Building a WEALTHIER Ontario: Hamilton’s Story.

From the laboratory bench to the patient’s bedside, health research and patient care go hand-in-hand. Within our institution, researchers have made ground-breaking discoveries in the areas of lung disease, kidney disease, infectious disease and mental health.

As the centre for a number of international clinical trials, the research we do helps keep Canadians healthier – resulting in fewer visits to the emergency department and an improved quality of life.

Developing new treatments for pulmonary fibrosis, asthma and allergies has saved the lives of thousands of Canadians – and has helped thousands more to breathe easier every day. International testing of new treatments for kidney disease has the potential to affect nearly 1.3 million Canadians who suffer from moderate to severe forms of kidney disease.

Working closely with our industry partners presents opportunity to commercialize the research discoveries created within our hospital. From the development of portable devices that can diagnose infectious diseases in only 20 minutes, to the creation of a video game that helps teenagers to recognize the signs and symptoms of psychosis, research at St. Joseph’s Healthcare Hamilton creates economic change while succeeding in its primary goal of improving patient care.

Innovation has taken many forms. St. Joseph’s Health System has succeeded in developing a new, integrated model of patient care that was successfully tested at St. Joseph’s Healthcare Hamilton.

This pioneering Integrated Comprehensive Care project provides patients with a continuity of care that stretches across each step in the patients’ journey, from hospital to home, and provides a new holistic patient experience for the 21st century. Winning a Canadian leadership award for innovation in improving outcomes, the success of the Integrated Comprehensive Care project has resulted in the province beginning to adopt this model across Ontario.

By working together with our colleagues across Hamilton as well as the patients that we serve, research at St. Joseph’s Healthcare Hamilton works to make Ontario a healthier, wealthier and smarter place for everyone.

Health Research and Business: Collaborating on a New Economic Future for Hamilton

Known more for our industrial legacy, the Hamilton renaissance is being driven by an economy that, according to the Conference Board of Canada, is this country’s most diversified.

The abundance of intellectual and institutional assets associated with our healthcare and academic partners at Hamilton Health Sciences, St. Joseph’s Health Care, McMaster University and Mohawk College give our economy a strong foundation in the growth industries that are “eds” and “meds”. The combined forces of healthcare and academia in Hamilton has led to a prosperous health research community that’s impacting health on a local and global scale.

While there is downward pressure to control costs, there is upward pressure to embolden Hamilton’s world-class researchers and clinicians to create better innovations that will help improve care while reducing costs. And with the efforts of key leaders in Hamilton’s anchor institutions, an entire network of community stakeholders is being mobilized in support.

There is a strong, and necessary, relationship to be nurtured between Hamilton’s life science research institutions and the local and global businesses that are capable of commercializing their discoveries. Research hospitals and health-focused academic institutions produce scientific and technical knowledge, but they must build partnerships and tap into other resources, like innovation incubators, as they navigate the pathway towards commercialization.

This is happening now in Hamilton. The knowledge infrastructure needed to create health-related ripple effects throughout the Hamilton economy is coming into place. Watch Building a WEALTHIER Ontario: Hamilton’s Story to learn more.

  • Hamilton Health Sciences, employing around 11,000 professionals in Hamilton, is one of the three largest hospital systems in all of Canada. St. Joseph’s isn’t far behind, employing 7,500 professionals in our city.
  • Both institutions, with their formidable clinical trial activity and lab infrastructure, are highly ranked research institutions producing world-class research, in partnership with McMaster University and Mohawk College.
  • All those institutions are working with the Hamilton business community, including the Hamilton Chamber of Commerce, the City of Hamilton’s Economic Development Department and Innovation Factory, Hamilton’s regional innovation centre, to create the ecosystem necessary to encourage commercialization.
  • The stakeholders are working to create a brand, and then tell our community’s story better to the potential partners and funders needed to fuel commercialization and build channels around the world.

With all these necessary ingredients coming into place, Hamilton’s life sciences sector is poised to create new, sustainable economic and social wealth in our community and beyond while driving the future of health care. That’s how Hamilton is contributing to a healthier, wealthier, smarter province.

Building a WEALTHIER Ontario: Hamilton’s Story

Building a WEALTHIER Ontario: Hamilton’s Story

As key drivers of Ontario’s knowledge-based economy, research hospitals contribute to a wealthier province by creating innovative, cost-effective products, establishing spin-off companies and partnerships, attracting investment from at home and abroad, and generating high-level jobs.

Across the province, communities are moving towards knowledge-based economies, and Ontario’s research hospitals are helping them get there. To illustrate that transformation, we took a focused look at the city of Hamilton. Traditionally known as Ontario’s steel town, the city has seen significant growth and renewal as a result of its health research sector. And, in the words of Mayor Fred Eisenberger, that growth feeds on itself.

“Once the ball starts rolling, it just doesn’t stop”

In our Wealthier video, Mayor of Hamilton, Fred Eisenberger, explains that the health research sector has led to a spillover effect on the economy—and the community.

The city’s success in health research has led to the growth of its educational institutes. Mohawk is now ranked as one of the top colleges in Ontario with many programs geared towards applied science, and McMaster’s medical school continues to climb on Canada’s top ten list, attracting more and more bright minds. And as Hamilton’s two research hospitals—Hamilton Health Sciences and St. Joseph’s Healthcare—continue to create more high-level jobs, the city is able to retain those bright minds and attract new ones.

Outside the walls of health research, the sector is having a spillover effect on the community, generating a vibrant arts scene, lots of cafes and shops, and more people living and working in revitalized neighbourhoods.

The story of Hamilton offers just one example of the impact that research hospitals are having on communities in Ontario. Thunder Bay, Sudbury, Ottawa, Kingston, Toronto, and London can all speak to similar growth and spillover. In ten years, we can only imagine what that spillover will look like for these communities, and for the province of Ontario.

Quick Facts: Ontario’s Research Hospitals

  • Employ 18,000 researchers and research staff
    • That’s more than twice the number employed at Ontario’s research-based pharmaceutical companies
    • That’s half of the number employed at the assembly plants of Ontario’s big 5 automotive companies
  • Support 41,000 jobs across Ontario
  • Invest $1.4B in health research annually
  • Commercialized 350 new health products in the last four years
  • 14% of research investment comes from private industry
  • Every dollar spent on health research generates three dollars of economic output
