Mixed-methods studies: what, why & how

Dr. Lawrence Mbuagbaw, Associate Professor, Health Research Methods, Evidence, and Impact

Mixed method studies are increasingly being used in health research. They represent a third research paradigm in addition to qualitative and quantitative studies.

However, they are poorly understood and frequently misused and mislabelled. This talk will cover the theory and practice of mixed methods studies and their value in health research.

A pilot prospective safety trial of delivering anticoagulation therapy in children at risk of thrombocytopenia

Dr. Felipe Fajardo, PGY2

Supervisor: Dr. Mihir Bhatt

There is a lack of evidence surrounding the delivery of anticoagulant therapy (ACT) in the context of concurrent thrombocytopenia. This study is a prospective pilot study that will investigate the safety of delivering anticoagulant therapy (ACT) according to our institutional protocol for patients with a thromboembolism who are at risk for thrombocytopenia. This will provide further evidence for the safety of this protocol in assessing any major or clinically relevant non-major bleeds.


  • To review the literature surrounding anti coagulation therapy and thrombocytopenia
  • To discuss our plans for the prospective study assessing the safety of our institutional protocol regarding ACT and thrombocytopenia

Cyclescapes: Exploring the role of virtual reality cycling for health promotion

Dr. Joyce Obeid, Assistant Professor, Department of Pediatrics

Virtual reality (VR) is a novel tool being used increasingly in clinical settings to engage patients in an immersive, digitally-generated environment. Combining VR and physical activity may allow children with frequent or prolonged hospital visits to maintain or improve their fitness and function, interact with peers, while also providing an escape from the real-world hospital environment. In this presentation, Dr. Obeid will share the on-going development of a VR-based cycling game and discuss the study’s next steps.

This project will be the focus of her upcoming Early Career Award application to the Hamilton Health Sciences. Feedback from attendees on the proposed methods, participant sample, and study outcomes will help to shape the final submission.


  1. To review the role and potential for VR in a clinical setting.
  2. To outline the rationale and proposed methods for an upcoming submission to the Hamilton Health Sciences Early Career Award.

Pediatric Celiac Symptom Index: Development of a patient-reported outcome measure for children with Celiac Disease using a mixed-methods approach

Lee Hill, Research Coordinator, Division of Gastroenterology, Department of Pediatrics

PI: Dr. Jenna Dowhaniuk, Assistant Professor, Department of Pediatrics

Patient-reported outcome measures are instruments used to measure outcomes of healthcare using a patient-centred approach. The aim of our research is to develop a pediatric celiac symptom index using a mixed-methods approach. The methods include a scoping review of the literature, qualitative interviews with patients and their caregivers, cognitive interviews once a preliminary Index has been developed, and finally a quantitative analysis of the Index. The research is being conducted over two phases and is currently nearing the completion of the first phase.


1) Understanding the role of mixed methods and how it can be applied to research.
2) Understanding the development of a patient-reported outcome measure
3) Understanding the barriers and facilitators to conduct a mixed methods research study.

Success at CIHR: Reflections on the journey

Dr. Rahul Chanchlani, Associate Professor, Department of Pediatrics

Four new pediatric studies, led by teams in the Faculty of Health Sciences and from research centres across Canada, have cumulatively been awarded $5 million by the Canadian Institutes of Health Research (CIHR) over the next five years. As one of the successful principal investigators, Dr. Rahul Chanchlani will lead a team in developing new reference standards to assess high blood pressure in South Asian children. The study titled “Deriving 24-hour ambulatory blood pressure monitoring reference values for SouTh AsiaN Children (ABPM-STANCE),” will also consider the impact of lifestyle factors like physical activity and sleep on 24-hour blood pressure.

In this session, Dr. Chanchlani will share key learnings from the grant submission and review processes that have culminated in his success at CIHR and discuss the objectives, methods, and implementation of his study.

Canadian pediatric resident doctors’ understanding of climate change and its health effects

Dr. Candace Nayman, PGY2

Supervisors: Drs. Ania Van Meer & Anna Gunz

Climate change and extreme weather events have a profound impact on human health. Pediatricians and pediatric residents have a duty to ensure that their patients are aware of the effects of the environment on their health and must be equipped to help them make informed decisions. However, it is unclear what Canadian pediatric residents understand and know about climate change and its effects on pediatric health, as this has never been studied. We will be surveying Pediatric resident physicians on a national level to gain a further understanding of their awareness and perceptions, as well as gathering data such as where they grew up, where they are completing their training, etc, to try to identify any variables that may influence their beliefs.


  1. To explore the importance of climate change as a determinant of health and why this research is essential to pediatric health.
  2. Discuss strategies to optimize resident response without biasing the data.
  3. Elaborate on research questions and ensure they are clear and answerable with the current research strategy.

Factors Associated with the Development of Dyslipidemia Among Pediatric Patients with Diabetes: A single-center based study

Dr. Fahd Alshammri, PGY2

Supervisor: Dr. Katherine Morrison

This presentation will review dyslipidemia in pediatric patients with diabetes, what are known as risk factors and what are the complications. Will also present our ongoing research project that is evaluating dyslipidemia in patients following at McMaster Children’s Hospital diabetes clinics.


  • Brief overview of dyslipidemia in pediatric patients with diabetes
  • Review a research project to evaluate dyslipidemia in patients followed at McMaster Children’s Hospital diabetes clinics.
  • Discuss & gather feedback on the study design, methods and data analysis plan

Barriers to providing optimal care to complex care patients in the Emergency Department

Dr. Sarah Altamimi, PGY2

Supervisor: Dr. April Kam

This session will provide an overview of a qualitative study looking at barriers to providing optimal care to complex care patients in the Emergency Department setting by exploring four commons themes and questioning Emergency Department staff and fellows.

Objectives include:

  1. describing complex care patients
  2. exploring barriers to care in the ED setting
  3. reviewing statistical approaches to study data

Virtual clinic: A novel access to urgent care for children with medical complexity

Dr. Smita Roychoudhury, PGY2

Supervisor: Dr. Audrey Lim

This presentation will discuss plans for a retrospective chart review comparing patient outcomes following face to face visits for urgent consultation compared to virtual visits. The research purpose is to see if virtual clinics are feasible as well. Virtual clinics, if found to be equivalent, may be a safer alternative that will not only prevent caregivers from missing work or spend time travelling but also may help them to be comfortable at home.

Project Objectives:

To determine, for urgent concerns of parents/caregivers
a. If a virtual clinic is feasible and comparable to face-to-face clinics with patient assessments and outcomes
b. If a virtual clinic will help with efficient healthcare resource allocation as well parent/patient’s resources while not adversely affecting patient outcomes
