Improving recovery and rehabilitation for patients with mental illness
Over 130 hospital-based clinical, administrative and research staff members, persons with lived experience of mental illness, family caregivers, peer and community supporters, and staff from local community mental health agencies attended the 18th Annual Mental Health Research & Innovation Half Day on November 1, 2017. The event provided an opportunity to learn more about mental health research at Parkwood Institute and the Southwest Centre for Forensic Mental Health Care (Southwest Centre), part of the St. Joseph’s Health Care London (St. Joseph’s) family.
“This year’s Mental Health Research and Innovation Half Day was one of the best attended in our history of hosting the event. We had a very diverse and engaged audience with great energy and a lot of enthusiasm,” says Dr. Arlene MacDougall, Director of Research and Innovation for mental health care at St. Joseph’s and Lawson Health Research Institute (Lawson).
Exciting recent projects were showcased though talks highlighting excellence in recovery and rehabilitation research, the theme of this year’s event; poster presentations; the 13th Annual Tony Cerenzia Research Lecture delivered by Dr. Sean Kidd; and interactive workshop sessions.
“We chose ‘recovery and rehabilitation’ as the theme for the event because it is so important in our clinical care and research programs to have this focus. We need to prioritize the development, implementation and evaluation of practices and interventions that foster recovery of the whole person experiencing mental illness, which includes their psychological, social and other needs that go beyond traditional notions of healthcare,” Dr. MacDougall adds.
13th Annual Tony Cerenzia Research Lecture
Guest speaker Dr. Kidd’s talk – “From clinical trials to the clinic: A story about making Cognitive Adaptation Training for schizophrenia more accessible” – focused on how to implement interventions proven in clinical trials. Dr. Kidd is a clinical psychologist, senior scientist and psychology division chief at the Centre for Addiction and Mental Health (CAMH) in Toronto. He is also an associate professor in the Department of Psychiatry at the University of Toronto.

Workshop Sessions
Following Dr. Kidd’s lecture, attendees had the opportunity to participate in one of six workshops on a variety of topics related to recovery and rehabilitation focused mental health research:
“Implementing Interventions: A facilitated conversation attending to evidence, strategy, and recovery oriented care”
Led by Dr. Sean Kidd
Participants shared successful strategies for implementing novel approaches to care and discussed the challenges involved. They also looked at ways to leverage technology and education materials.
“Spirituality in Mental Health Care: Practically Supporting Recovery and Wellness”
Led by Stephen Yeo, Lawson allied scientist and chaplain, Southwest Centre; and Dr. Clark Heard and Jared Scott, Lawson associate scientists and occupational therapists, Southwest Centre
This workshop focused on the practical application of spirituality within the clinical setting, including the use of labyrinths, which contribute to recovery by promoting spiritual self-care, insight development and personal meaning-making reflection. Attendees had the opportunity to participate in a labyrinth walk and a related spiritual reflection.

“My Professional Practice: Where's the Research?”
Led by Amanda Thibeault, director, professional practice, St. Joseph’s
In this session, participants discussed how they can incorporate research into their clinical practice (pictured below).
Investing in life-changing research
Through donor support, endowed research chairs are exploring and answering some of the most profound and complex research questions of our time.
Among cherished family photos and special mementos in the office of Jeremy Burton, PhD, is a slightly faded photo of a young woman. Burton points out the framed photo as he enthusiastically talks about his work. It’s a young Miriam Burnett, after whom the Miriam Burnett Chair in Urological Sciences is named. It’s also the first endowed research chair position Burton held at St. Joseph’s Health Care London (St. Joseph’s).
As the research chair for seven years, Burton speaks fondly about the relationship he has with the Burnett family and the crucial role their support has played in advancing his research.
“Thanks to their funding, we became one of the world leaders in urological microbiome research,” he says.
Endowed research chairs at St. Joseph’s receive consistent and sustainable funding so that research leaders and their teams can answer the most profound and complex health questions of our time.
For decades, donors have been inspired by the clinical research taking place at St. Joseph’s and have heavily invested in endowed research chairs. Today, St. Joseph’s Health Care Foundation manages seven endowed chairs focused on several areas, including molecular imaging, fetal and newborn growth and diabetes. Working in partnership with Western University, and with donor support, the foundation recently established four new endowed chairs in mobility, medical biophysics, medical imaging and ophthalmology.
“Medical research in Canada is chronically underfunded, and there is almost no sustainable funding for hospital-based research positions,” says Michelle Campbell, President & CEO, St. Joseph’s Health Care Foundation. “Private philanthropy has filled that gap for years. When a donor gives to an endowed research chair, they are building capacity in the present day and creating future value and opportunity. An endowed gift has a multiplier effect.”
Burton, now the endowed Research Chair in Human Microbiome and Probiotics, has many reasons to be grateful for this support. Not only does the endowed fund pay for Burton’s research salary, it also partially supports the salaries of a lab manager and technical team – all vital for a sophisticated lab to be successful.
The funding also provides the gift of time – a diminishing commodity for any busy research team.
“Scientists need more time to think,” says Burton, a Lawson Research Institute (Lawson) scientist. “We are incrementally being stretched in multiple directions, and the funding gives us the time to do what we are meant to do – find answers to important clinical questions and find solutions to medical problems.”
Distinguished Lawson scientist and university professor Cheryl Forchuk, PhD, wholeheartedly agrees. She recently completed her final term as The Beryl and Richard Ivey Research Chair in Aging, Mental Health, Rehabilitation & Recovery, another endowed position. As Chair, Forchuk provided scientific and administrative leadership to a large group of researchers based at St. Joseph’s Parkwood Institute focused on mental health, activity and mobility, and cognitive vitality and brain health.
Many research leaders, she explains, can afford to spend only two days a week on their own research projects. Endowed chair positions change that.
“Imagine travelling across the country to create a national study focused on homelessness, two days a week at a time,” she suggests candidly. “You couldn’t.”
Forchuk is referring to her landmark project to better understand how many people in Canada are homeless and who they are. The goal was to develop more accurate sources of data and recommend appropriate support and services. Her work is already resulting in important changes.
Today, Forchuk is embarking on another cross-country research project to find solutions related to homelessness for Canadian veterans who are women.
Like Forchuk, Burton’s Chair position requires him to provide operational and research leadership, including developing research networks and partnerships nationally and internationally to advance studies that will revolutionize care.
“As the Chair, I think it is important that I have wide-ranging projects that benefit people in our own community and beyond,” says Burton, who is optimistic about the outcomes of several of his team’s studies.
He recently partnered with London’s First Episode Mood and Anxiety Program to study the impact of fermented foods on the microbiome of young people taking medications for mental health conditions.
One of the side effects of these medications is weight gain, which deters some patients from taking it. By providing patients with slow-release apple cider capsules, which have similar properties to fermented foods and positively affect the microbiome, they have seen an overall improvement in participants’ mental health and cholesterol after just a few months.
Reflecting on his team’s research achievements to date and the potential of what’s to come, Burton emphasizes how vital endowed chairs are to the sustainability of research and the hope to translate newly discovered knowledge into medical practice.
“Research funding from other sources comes and goes,” he says, “but endowed chair positions that are focused on improving human health provide continuity, build research and create change benefiting all of us.”
Keeping an eye on care of the future
Dr. Khaldon Abbas is using his curiosity and passion for ophthalmology to improve patient care and outcomes for people with eye diseases and disorders.
While in university, Dr. Khaldon Abbas had a deeply moving experience as a volunteer with the Canadian Centre for Victims of Torture (CCVT) that changed the trajectory of his life and career.
The community-based organization helps victims of war and torture, and Abbas, whose family immigrated to Canada from Iraq a little more than a decade before, wanted to share his skills as a translator and tutor with newcomers.
“I came to Canada when I was 12. I had limited English, we had no family or friends here, and it was really hard to acclimate,” says Abbas. “I wanted to give back to the community and to be there for immigrant families who were facing similar challenges that my family had to deal with.”
During one shift with CCVT, Abbas was paired with a family from Syria, whose nine-year old daughter was losing her eyesight. She was living with retinal dystrophy, a degenerative disorder that can progress to complete blindness.
Witnessing the impact the eye disorder had on the young girl and her family inspired Abbas to further his own education and set a goal to become an ophthalmologist.
That was eight years ago. Since then, Abbas spent several years working as a clinical research coordinator and completed four years of medical school at the University of British Columbia.
Today, he is a clinical research fellow at the Ivey Eye Institute of St. Joseph’s Health Care London (St. Joseph’s) – a position supported through St. Joseph’s Health Care Foundation thanks to the generosity of donors.
During the next year, Abbas’ research will focus on improving patient care and outcomes for people with eye diseases and disorders.
Drs. Phil Hooper, Verena Juncal and Tom Sheidow, all retinal surgeons at Ivey Eye, are the impetus behind the fellowship and now serve as Abbas’ mentors. Through the fellowship, the trio wanted to expand their clinical research program which is heavily focused on clinical trials. Their goal was to delve into quality improvement projects and explore, among other things, patient data, referral patterns and wait times – information that could guide Ivey Eye in refining care to better understand how to improve the overall flow of patient care.
As surgeons at the largest single-site eye care centre in Canada committed to innovative care, the Ivey Eye physician leaders felt a responsibility to make this work a reality.
“We started talking about this about three years ago,” says Sheidow. “We were familiar with similar roles at other academic eye care centres and we were fortunate to have some funding, so we brought the idea to the foundation and started to craft the terms of reference,” he adds.
Abbas is the second physician in this fellowship, following in the footsteps of Dr. Amy Basilious, who is now in her second year of residency at Ivey Eye.
“Amy did an exceptional job as our inaugural fellow and we were looking for someone with similar characteristics – bright, curious, motivated, a self-starter and a passion for ophthalmology,” says Sheidow. “Khaldon has all of that and more,” he adds, referring to Abbas’ interest and background in clinical trial work.
Even before arriving in London for the fellowship, Abbas began working with his new team to generate research project ideas and shape a research plan. Among the projects he will tackle is one that will assess the effectiveness and complications of lens exchange surgeries, and another in collaboration with Basilious focused on macular hole repairs.
He will also spearhead two quality improvement studies aimed at streamlining the referral process to Ivey Eye for optometrists and enhancing education and information resources for patients with eye diseases and disorders. Through his work, Abbas is excited to build his research skills, forge new professional connections and see some of his research translated into tangible improvements in patient care.
He’s grateful to Hooper, Juncal and Sheidow, along with St. Joseph’s and the Foundation, for their vision and spirit of innovation in establishing the fellowship.
“Everyone has been extremely welcoming and supportive of me, especially my mentors and fellow co-workers” he says. “There’s a real family environment at St. Joseph’s. I feel like this is my new home away from home.”
Lawson homelessness researcher Cheryl Forchuk to receive Coronation Medal
Prestigious award will honour the national impact of Forchuk and her research into health and homelessness
Lawson Research Institute scientist Cheryl Forchuk, PhD, will be awarded the prestigious King Charles III Coronation Medal in honour of her groundbreaking health care research in the region and across the country.
Forchuk, who is also a Distinguished University Professor of Nursing in the Faculty of Health Sciences and in the Department of Psychiatry at Western University, will receive the medal in a special presentation ceremony in London on April 23.
In nominating Forchuk, London North Centre MPP Terence Kernaghan said the medal “recognizes outstanding individuals for their profound and lasting contribution to Ontario and to Canada.”
He said Forchuk has shown “exemplary leadership and ground-breaking work in mental health, homelessness, and the systems and models of care you’ve developed.”
Her important work has helped shape national perspectives and treatments for people experiencing homelessness – in particular, people with experiencing homelessness and mental health and/or homelessness and addiction.
Forchuk’s research studies have also influenced national policy in understanding and redressing veterans’ homelessness, in London and across Canada. She is currently conducting nation-wide research into specific issues experienced by women veterans who are homeless.
Forchuk said she was honoured to be nominated and selected for the medal, and that her work related to improving homelessness and mental health challenges including addiction could not have been possible without the assistance of many others. This assistance includes people with lived experience, multiple community and hospital partners, and her team of research coordinators, research assistants and students. Forchuk recently completed her term as The Beryl and Richard Ivey Research Chair in Aging, Mental Health, Rehabilitation & Recovery, an endowed position supported by the St. Joseph’s Health Care Foundation.

Lawson researchers elected to Royal Society of Canada
Drs. Cheryl Forchuk and Ruth Lanius have been elected as Fellows with the Royal Society of Canada (RSC) in recognition of their significant contributions to mental health research.
Dr. Forchuk, Assistant Scientific Director at Lawson and the Beryl and Richard Ivey Research Chair in Aging, Mental Health, Rehabilitation and Recovery at St. Joseph Health Care London’s Parkwood Institute, has worked tirelessly to advance research that has resulted in improved hospital discharge models, harm reduction strategies and support for those living without housing, among other concerns. Most recently she has hosted forums across Canada in an effort to better understand homelessness and the number of people experiencing it.
“It’s an honour to be included among such a talented group and alongside my mental health colleague,” says Dr. Forchuk, who is also a Distinguished University Professor at Western University. “A lot of important work remains to be done to better support those living with mental health challenges.”
Dr. Lanius, Associate Scientist at Lawson and Psychiatrist at London Health Sciences Centre, is world-renowned for advancing the understanding and treatment of post-traumatic stress disorder (PTSD) through her research. She has been instrumental in defining different types of PTSD and combining imaging and psychiatry to develop new therapies that use neurofeedback or sensory processing to ‘train the brain.’
“Advancing knowledge is crucial to improving quality of life,” notes Dr. Lanius, who is also the Harris Woodman Chair in Mind-Body Medicine and a Professor at Western’s Schulich School of Medicine & Dentistry. “I’m very excited to be recognized with such a distinguished group of contributors to research and academics.”
RSC fellows are elected by peers for their outstanding scholarly, scientific and artistic achievement. This year’s 101 new fellows will be inducted into the RSC on November 17.
London expands approach to prevent discharge from hospital to homelessness
LONDON, ON - During a virtual event for Londoners hosted by Lawson Health Research Institute and the City of London, a multi-sectoral research team announced two projects representing a collaborative approach to preventing homelessness from within hospital walls.
Built on the unique and successful No Fixed Address (NFA) strategy, these projects are being tested as a potential best practice for preventing hospital discharge to homelessness. NFA seeks to stop the cycle between hospital admissions and homelessness by providing timely and accessible supports to patients who would otherwise be discharged into homelessness. It brings housing and financial supports into the health-care system, starting as soon as upon admission, to assist in finding appropriate housing and supports or avoiding a potential eviction.
“Canada lacks a validated and coordinated service model to address the issue of hospital stay to no fixed address, which can often be the beginning of an individual’s experience with homelessness,” explains Dr. Cheryl Forchuk, Beryl and Richard Ivey Research Chair in Aging, Mental Health, Rehabilitation and Recovery, and Assistant Scientific Director at Lawson. “There are multiple factors that cause people to be discharged into homelessness - systemic, organizational and personal. We need a collaborative and coordinated approach that honours housing as a basic human right.”
Several departments at London Health Sciences Centre (LHSC) and St. Joseph’s Health Care London collaborate with staff from the City of London, Canadian Mental Health Association (CMHA) Elgin-Middlesex, Youth Opportunities Unlimited (YOU), Salvation Army’s Housing Stability Bank and Ontario Works in the City of London to provide direct, on-site (or virtual) support for patients at risk of homelessness.
“Implementing a coordinated approach to addressing homelessness allows our staff to actively work alongside our partners in health care to prevent and divert individuals and families from an experience of homelessness by assessing their needs and connecting them to the housing supports.,” says John D’Oria, Coordinated Access Manager, City of London. “Whether it’s financial, social service or mental health support, this partnership and approach allows for a holistic approach to client care at the right time.”
Patients discharged from hospital to homelessness in Canada face many challenges that make recovery more difficult. They often experience higher readmission rates and emergency department visits. This is particularly concerning for youth, who have been found to be the fastest growing segment of the homeless population.
NFA was initially tested with strong success for mental health patients across the city and the second version of the project was extended to medical units at LHSC’s University and Victoria Hospitals.
PROJECT 1: Collaboration to Address Homelessness - Health, Housing and Income (H2I)
This research study will evaluate the City of London’s Coordinated Access Outreach program at hospital sites. A Coordinated Access Outreach worker will support individuals at risk of homelessness to maintain or obtain housing. Ontario Works will assist with the provision of income and employment supports and the Salvation Army Housing Stability Bank may be accessed for needed financial resources to secure or maintain housing.
Over two years, 106 participants will be interviewed in hospital and again six months post-discharge. Focus groups with participants, health care providers and community partners will provide further insight into the effectiveness of NFA. This project is funded by the Canada Mortgage and Housing Corporation (CMHC)’s National Housing Strategy.
PROJECT 2: Preventing discharge to No Fixed Address – Youth (NFA-Y)
This research study will customize, implement and evaluate the NFA strategy for vulnerable youth ages 16-24. The unique health and housing needs of youth at-risk will be explored by streamlining housing and financial support into a coordinated system of care, with additional support provided by Youth Opportunities Unlimited and Children’s Aid Society London and Middlesex.
Over 3-4 years, data to be collected from 93 youth at three time points. Focus groups with youth participants, health care providers, and community agency partners will help enhance the NFA strategy to meet the unique needs of youth. This project is funded by the National Centres of Excellence (NCE) Making the Shift (MtS) Youth Social Innovation Lab.
