The results of the CIHR’s Spring 2021 Project Grant Competition have just been announced. CHÉOS Scientists are leading eight of the projects funded in this round, plus a further fourteen projects are supported by CHÉOS Scientists as co-investigators.
In Canada, there is currently a shortage of plasma, the liquid component of blood. CHÉOS Program Head of Decision Sciences Dr. Nick Bansback is leading a survey of existing blood donors and non-donors to understand what influences their willingness to donate in order to determine what locations and features might result in the most plasma donations. CHÉOS Scientist Dr. Mark Harrison is a co-investigator on this project. Dr. Bansback is also a co-investigator on a project developing a personalized decision aid to help patients choose the best rheumatoid arthritis treatment, in addition to a project identifying and updating information on rheumatoid arthritis treatments to inform physician/patient discussions.
CHÉOS Director Dr. Aslam Anis and Program Head of Health Economics Dr. Wei Zhang are leading an evaluation of Canada’s upcoming drug pricing regulations and determine the likely impact these regulations will have on taxpayers and pharmaceutical companies. As Dr. Anis explains, “Our study will produce evidence-informed recommendations on the Patented Medicine Prices Review Board price regulations that will have broad implications for Canada’s drug expenditures and access to essential medicines.”
CHÉOS Scientist Dr. Larry Lynd is co-principal investigator on a study that will use patient and clinical data to develop and test a series of predictive models in multiple sclerosis (MS) to help guide personalized therapeutic approaches and improve patient-level decision-making. These models will be made freely available online. CHÉOS Scientists Drs. Annalijn Conklin and Mary De Vera are co-investigators on this study.
CHÉOS Scientist Dr. Bohdan Nosyk will join Program Head of Biostatistics Dr. Hubert Wong to lead an evaluation of Suboxone microdosing in BC and Alberta. The team will identify adult patients with opioid addiction in emergency departments, and provide them with either take-home Suboxone microdosing or standard dosing packages to start after they are discharged to determine who is more likely to stay on treatment. CHÉOS Scientist Dr. Andrew Kestler is co-investigator on this project. Dr. Wong is also a co-investigator on a randomized controlled trial testing cannabidiol as a treatment for the depressive phases of bipolar disorder.
Alongside CHÉOS Health Economist Emanuel Krebs, Dr. Nosyk is also leading a project estimating the impact and cost-effectiveness of the harm reduction, opioid agonist therapy (OAT), and safe supply interventions that have been introduced in BC since 2016 to determine if these initiatives have reduced opioid overdose death across the province.
CHÉOS Scientist Dr. Najib Ayas is principal investigator of research into whether oxidative stress/inflammatory biomarkers can help predict long-term health complications in obstructive sleep apnea, such as kidney damage and dementia, and determine whether CPAP adherence improves outcomes.
CHÉOS Scientist Dr. Sarah Munro is co-leading a collaboration between Indigenous communities, researchers at UBC, the BC First Nations Health Authority, Vancouver Coastal Health Authority, the ekw’i7tl doula collective, and health care professional organizations. Together, they seek to understand Indigenous peoples’ experiences of accessing family planning care and what approaches to family care are best suited to Indigenous communities, contexts, priorities, and needs.
In response to the opioid overdose crisis, BC policy-makers have implemented several changes to encourage physicians to expand access to OAT. Meanwhile, the College of Physicians and Surgeons of British Columbia released a new practice standard setting enforceable thresholds for prescribing. CHÉOS Scientist Dr. Rita McCracken is co-principal investigator of an analysis of the consequences of changes to OAT prescribing and the College’s practice standards for patients and physicians.
CHÉOS Program Head of Clinical Trials Dr. Joel Singer is a co-investigator on four projects. One project, led by Dr. Deborah Money, will analyze the effectiveness of a reduced dosing regimen of the HPV vaccine for women living with HIV. As part of an ongoing collaboration with UBC Okanagan, one project will evaluate the implementation and effectiveness of the Small Steps for Big Changes (SSBC) diet and exercise intervention. Another project he is involved in, led by Dr. Teresa Liu-Ambrose, will evaluate the effect of twice-weekly targeted exercise training on sleep quality in people with chronic stroke and poor sleep quality. Finally, Dr. Singer will join CHÉOS Statistician Dr. Terry Lee on a project investigating the effectiveness of a telehealth intervention (CANATEXTS) on improving health outcomes among asthma patients.
CHÉOS Scientist Dr. Skye Barbic is serving as a co-investigator on a project looking to identify strategies to address the health and social needs of youth who use stimulants that are culturally safe for diverse genders, sexual identities, and for youth who are racialized and exposed to living on the streets. Alongside CHÉOS Scientist Dr. Mieke Koehoorn, Dr. Barbic is also a co-investigator on a study assessing economic activities and their impacts on individual health and wellbeing.
CHÉOS Scientists Drs. Naveed Janjua, Troy Grennan, and Caren Rose are co-investigators on a project calculating sexually transmitted infection (STI) testing rates and patterns, assessing how they relate to diagnosis rates, and identifying populations that may benefit from additional testing and prevention efforts.
CHÉOS Scientist Dr. David Barbic is a co-investigator on the largest study ever conducted on people who are prescribed blood thinners with a head injury, led by Dr. Kerstin de Wit. The team will recruit 5,000 patients from Canada, Britain, and the United States to develop a new bedside decision rule, which will indicate whether or not the patient needs a CT scan.
CHÉOS Scientist Dr. Tara Sedlak is a co-investigator on a randomized, prospective, placebo-controlled study investigating whether atomoxetine is an effective treatment for frequent fainting. If it is, they will also determine the costs of use, peoples’ feelings towards the drug, and how quickly other doctors can be taught to use it.
CHÉOS Scientist Dr. John Staples is serving as a co-investigator on a project investigating the circumstances around active transport injuries, how quickly injured pedestrians and cyclists recover, which patients are more likely to have long-term health issues, how much medical treatment is needed, and how much work patients miss. The results could help inform city planning and support policy-makers’ decisions on what resources are needed to prevent or treat pedestrian or cyclist injuries.
