"Man Up": Male Survivors Of Intimate Partner Violence Through The Eyes Of Their Providers, Xavier S. Borsato

Electronic Thesis and Dissertation Repository

Intimate partner violence (IPV) is a complex phenomenon that is often understood with women as the primary recipients of violence and men as the primary perpetrators. However, emerging literature on heterosexual relationships suggests that men also experience interpersonal violence, most often from their female partners. Drawing on research data gathered through semi-structured interviews with service providers (n = 4), this qualitative inquiry explores how gender, power, and the stigma associated with interpersonal violence impact men who have experienced abuse through the perspectives of the service providers who work with them. The findings from this study highlight how traditional constructions …

Analysis Of Health Care Costs Over A One-Year Period Following Anticoagulant Therapy Among Ontario Patients Diagnosed With Atrial Fibrillation, Michael Situ

Electronic Thesis and Dissertation Repository

Atrial fibrillation patients are at high risk of ischemic strokes, which can be drastically reduced using oral anticoagulants (OACs). Warfarin has been the standard OAC for this population but its effectiveness rests on consistent monitoring with the potential for severe bleeding events. Newer OACs, like rivaroxaban and apixaban, address these drawbacks but have a comparatively higher upfront cost. Uncertainty remains over which OAC is cost-saving from a health care system perspective. Using a retrospective cohort study design and inverse probability weighting regression adjustment estimators, one-year health care costs among patients treated with warfarin, rivaroxaban, and apixaban were compared. Compared to …
