Background Wernicke-Korsakoff Syndrome (WKS) is a neuropsychiatric syndrome caused by thiamine deficiency. Cancer predisposes to thiamine deficiency through various mechanisms. Although many case reports exist on nonalcoholic WKS in cancer, larger qualitative studies are lacking. Method Retrospective study of patients admitted to a cancer hospital and diagnosed with WKS during routine care on a psychiatric consultation service. Only patients with at least 1 additional supporting feature (magnetic resonance imaging findings, low serum thiamine concentrations, or response to treatment) were included. Data pertaining to demographics, risk factors, phenomenology, and outcomes were abstracted from medical records by chart review. Results In all, 18 patients were included. All patients developed WKS during cancer treatment. Hematologic malignancy, gastrointestinal tract tumors, low oral intake, and weight loss were common risk factors. All patients presented with cognitive dysfunction, most commonly impaired alertness, attention, and short-term memory. All were diagnosed by operational criteria proposed by Caine et al., 1997 (where 2 of the following are required: nutritional deficiency, ocular signs, cerebellar signs, and either altered mental status or mild memory impairment). Few exhibited Wernicke’s classic triad. Diagnostic and treatment delay were common. Only 3 patients recovered fully. Conclusion Nonalcoholic WKS can occur during cancer treatment and manifests clinically as delirium. Diagnosis should be made using operational criteria, not Wernicke’s triad. Most patients were not underweight and had normal serum concentration of vitamin B12 and folate. A variety of mechanisms might predispose to thiamine deficiency and WKS in cancer. Given the high frequency of residual morbidity, studies should focus on decreasing diagnostic and treatment delay.

ObjectiveThe road to legalization of Medical Assistance in Dying (MAID) across Canada has largely focused on legislative details such as eligibility and establishment of regulatory clinical practice standards. Details on how to implement high-quality, person-centered MAID programs at the institutional level are lacking. This study seeks to understand what improvement opportunities exist in the delivery of the MAID process from the family caregiver perspective.MethodThis multi-methods study design used structured surveys, focus groups, and unstructured e-mail/phone conversations to gather experiential feedback from family caregivers of patients who underwent MAID between July 2016 and June 2017 at a large academic hospital in Toronto, Canada. Data were combined and a qualitative, descriptive approach used to derive themes within family perspectives.ResultImprovement themes identified through the narrative data (48% response rate) were grouped in two categories: operational and experiential aspects of MAID. Operational themes included: process clarity, scheduling challenges and the 10-day period of reflection. Experiential themes included clinician objection/judgment, patient and family privacy, and bereavement resources.Significance of resultsTo our knowledge, this is the first time that family caregivers’ perspectives on the quality of the MAID process have been explored. Although practice standards have been made available to ensure all legislated components of the MAID process are completed, detailed guidance for how to best implement patient and family centered MAID programs at the institutional level remain limited. This study provides guidance for ways in which we can enhance the quality of MAID from the perspective of family caregivers.
