Poster Session for STAT 450

STAT 450 students have worked collaboratively on real case studies brought by researchers from other disciplines. Supervised by the teaching team, STAT 450 students performed various statistical analyses to address their “client’s” questions. Results from seven exciting projects are presented in this poster session. 

Poster 1: Return of Service in BC: Retention Outcomes and Physician Experiences

Collaborators: Romina Moradi (BC College of Family Physicians, University of British Columbia), Chiara Piccolo (University of British Columbia), Ashley Woods (University of British Columbia), Angele Bonin (University of British Columbia), Yebi Okay-Inneh (University of British Columbia)

STAT 450 Team: Elliot Au, Zhihan Dong, Samin Intisar, Jellia Ma

This project investigates whether physicians stay in their assigned communities after completing a Return of Service (ROS) contract, and what factors influence their decision to stay or leave. Beyond retention, the study also examines how ROS may affect physicians’ careers, personal well-being, and perceptions of equity within the system.

Poster 2: Dentist perception of TeleDentistry Application information to facilitate the delivery of care at the first visit for frail older adults residing in long-term care: a pilot study

Collaborators: Maureen Perzan (UBC Faculty of Dentistry)

STAT 450 Team: Olivia Jiang, Roberto Mulliadi, Emma Oh, Yoona Wang

This study evaluates whether a TeleDentistry referral application helps dentists deliver care for residents of long-term care facilities compared to conventional intake methods. Using descriptive analysis and mixed-effects logistic regression, we assess whether TeleDentistry improves treatment decision-making while accounting for variability across dentists.

Poster 3: Contact Quantity, Contact Quality, and Attitudes Toward Sikhs: Mental Health Professionals in Private Practice Across Six Canadian Cities

Collaborators: Carrie Bove (Riverside Counselling), Robinder Bedi (UBC Department of Educational and Counselling Psychology) 

STAT 450 Team: Dansie Feng, Brianna Zhou, Raine Zhuang

This study examines how mental health practitioners’ contact with Sikh individuals, including both the frequency and perceived quality of interactions, relates to their attitudes toward the Sikh community across different practice environments. Using survey data from practitioners in six Canadian cities, we apply ordinal mixed-effects regression models to examine how contact experiences, practice environments, and practitioners’ attitudes are associated with one another.

Poster 4: Impact of rapid recovery protocol after femoral venous electrophysiology procedures: Analysis of shorter bedrest and vascular access complications 

Collaborators: Courtenay Disher-Trotter (Pulse Complete Cardiac Care, Vancouver Island Health Authority), Matthew Coxon (Victoria Cardiac Arrhythmia Trials), Martin Van Zyl (Pulse Complete Cardiac Care, Vancouver Island Health Authority), Kate Phillips (Vancouver Island Health Authority)

STAT 450 Team: Zhihua Li, Stellar Shar, Gary Wu

This study aims to investigate factors associated with post-ablation procedure bleeding events, with a particular focus on whether switching bedrest protocol from standard to accelerated is associated with the probability of bleeding. We used a logistic regression model to estimate and compare the probability of bleeding across different bedrest protocols and patient characteristics groups, and to evaluate their statistical significance, with the goal of providing support for physicians’ decision-making and clinical efficiency.

Poster 5: Use of the BC Cancer Clinical Guided PERT Tool in the identification and management of pancreatic enzyme insufficiency in pancreatic cancer 

Collaborators: JP McGhie (BC Cancer), Karina Austin (BC Cancer Victoria), Jacob Lemire (BC Cancer Victoria), Cara Miller (BC Cancer Victoria)

STAT 450 Team: Blasius Boniarga, Jerry Gai, Hayden Hong, Annmarie Thomson

Our project examines whether the BC Cancer Clinical Guided PERT Tool can offer a practical way to identify pancreatic enzyme insufficiency in pancreatic cancer patients, using stool test results as a benchmark, and explores how patients’ weight changes after treatment. We found encouraging evidence that the tool captures most PEI cases, making it a potentially valuable support for clinical decision-making.

Poster 6: Parasagittal and Falcine Meningiomas Exhibit Comparable Risk to Skull Base Lesions: A Single-Centre Retrospective Study

Collaborators: Mehdi Tabesh (UBC Faculty of Medicine)

STAT 450 Team: Yu Chang, Karn Shoker, Suying Wang, Justin Zhu

This project investigates whether meningioma location is associated with post-operative neurological complications, non-neurological complications, and length of hospital stay in a cohort of 421 surgeries performed in Vancouver between 2020 and 2024. Using mixed-effects logistic regression and a Cox proportional hazards model, we compare outcomes across major tumour locations while accounting for important patient and clinical factors.

Poster 7: Effect of increased interhospital transfer times on health outcomes in critical cardiac care in British Columbia and the Yukon

Collaborators: Krishnan Ramanathan (UBC Faculty of Medicine), Carolyn Taylor (UBC Faculty of Medicine), Shamikh Lakhani (UBC Faculty of Medicine) 

STAT 450 Team: Khue Do, Owen Kwong, Tamzeed Quazi, Honglu Zhu

Cardiac patients in rural British Columbia and the Yukon depend on timely interhospital transfers to facilities such as St. Paul's Hospital in Vancouver to access specialized care, yet little is known about what drives transfer delays or their consequences. Using regression and ANOVA models on 1,525 patient transfers, this study examines how rurality, priority designation, and clinical presentation relate to transfer duration, and whether transfer distances, rurality, and patient medication are associated with patient mortality.
