The day that I joined McMaster University and the Department of Health Research Methods, Evidence, and Impact as a Master student, I did not foresee the amazing journey I was embarking on or the impact of my academic achievements. I was continuously challenged to think critically and apply my ideas to real world problems. Seeing the opportunity to make a difference in clinical research and patient care inspired me to begin my PhD studies. Creating knowledge and applying it practically was a difficult task, however, the opportunities to share my research in a dynamic and complex field with the world fuelled my motivation. Completing a PhD has been an incredible privilege for which I will always be grateful.
To my family – Mamma, Papa, Mark and Matthew – thank you for your undying and unconditional love, support, and encouragement. A pandemic forced us to come together, and having your support 24/7 (literally) made the journey more enjoyable.
To my closest friends, thank you for being a part of my life and supporting my ambitions. We all recognized my ambitiousness would set me on a difficult path and completing a PhD was not my original plan. Thank you for inspiring me to take on the challenge and ensure my work was truly impactful. Thank you for encouraging mental strength, being understanding and willing to lend a hand, reminding me that I can achieve anything I set my mind to, and inspiring me to dare.
To my supervisory committee members and independent study supervisor, thank you for your continued interest in my work and for always supporting my ambitions. I am grateful for your patience and belief that I would succeed in completing what I had sought to achieve. Thank you for the chance to work together, and for your constant support and mentorship throughout my PhD journey.
To the faculty, staff and fellow students at the Department of Health Research Methods, Evidence, and Impact, and the McMaster Centre for Transfusion Research, thank you for providing the resources, friendship, and guidance I needed to achieve greatness.
To the panel members of the ITP Emergency Management Guideline, thank you for believing in this project and making this work possible. I look forward to implementing the results of our efforts into clinical practice.
To the ITP patient community, thank you for entrusting me with the task of improving patient care and supporting me along the way. You have enabled me to be a voice for change. To the rare disease community, I know the completion of my PhD journey will not be the end of our work together.
To the funding agencies who allowed this project to be possible, the Canadian Institutes of Health Research and Platelet Disorder Support Association, thank you for supporting my PhD journey and the completion of this important work.
To my doctoral supervisor, Dr. Donald Arnold, it has been an honour and privilege to have learned from you and received your guidance throughout my PhD journey. Since our initial meeting, when I hobbled into the McMaster Centre for Transfusion Research offices several minutes late, I felt that your kindness and honesty would be the perfect form of mentorship to push me towards success. Thank you for recognizing my ambition and reminding me to keep focused. I will continue to apply this lesson throughout my life and strive for ‘depth’. For many years, you have been my mentor who I reached out to for advice, support, honest feedback, and encouragement. Thank you for imparting your knowledge to me over my PhD journey and teaching me how to be an inspirational mentor who highlights the strengths of their students while simultaneously supporting their growth. Although I may have finally reached the destination in my PhD journey, I know that we will continue to collaborate for many years to come. / Developing clinical practice guidelines (CPGs) for rare diseases is methodologically challenging. As each disease has so few patients, published literature includes low-quality studies or studies that do not directly address the questions of interest. As a result, CPG panelists have limited evidence on which to base their recommendations. Historically, when no evidence was available, CPGs have relied on physician opinion. This does not align with the mandate of CPGs which transparently identifies, appraises, and relies on evidence.
The challenges of developing CPGs for rare diseases are exemplified by immune thrombocytopenia (ITP), a rare autoimmune disease that affects approximately 1 in 8,000 people. It predominantly affects females and young adults, and is characterized by low blood platelets that increase the risk of bleeding. Bleeding emergencies in ITP patients are critical, life-threatening events that can cause life-long morbidity and associated health care costs. Treatment of ITP bleeding emergencies requires a rapid, coordinated approach that involves emergency department staff, hematologists, pharmacy, and the laboratory. However, there is no evidence-based CPG for the management of ITP bleeding emergencies.
The objectives of my PhD thesis are (1) exploring the heterogeneity of ITP diagnosis using antiplatelet autoantibodies; (2) developing a standardized definition of ITP bleeding emergencies; (3) outlining the synthesis of existing evidence on the treatment of ITP bleeding emergencies through a systematic review; and (4) developing a novel methodology to address the lack of evidence in rare disease CPGs and applying it to develop a CPG for the management of ITP bleeding emergencies. / Thesis / Candidate in Philosophy / Guidelines for rare diseases can be hard to develop because of a lack of information. Doctors and researchers make decisions on rare disease management based on their experiences, which can be limited. Low blood platelets and emergency bleeding can be caused by a rare disease called immune thrombocytopenia (ITP). When emergency bleeds occur, patients need care from the Emergency Department immediately. The problem is that there is no standard way for doctors to treat these ITP bleeding emergencies.
My PhD thesis project will fill an important gap for ITP emergency treatment. First, we will assess how ITP patients are diagnosed. Second, we will define an ITP bleeding emergency. Third, we will collect existing information about ITP bleeds. Fourth, we will overcome the challenge of not having enough information by collecting new data from patient records. The method we use to develop ITP guidelines can be used for other rare diseases.
