Objectives Simulation research in postgraduate psychiatry remains limited, with minimal studies on interdisciplinary involvement and mechanisms of change. To address these gaps, the authors implemented a mixed-methods realist analysis of an interdisciplinary simulation intervention administered to psychiatry residents. Methods The University of Calgary implemented a simulation intervention for psychiatry residents. Eight junior residents participated in or observed 4 scenarios and eighteen senior residents participated in or observed 8 scenarios. Scenarios lasted 15 minutes with a pre-simulation orientation and post-scenario debrief. Most scenarios involved interdisciplinary staff. Scenarios included agitated and suicidal patients; treatment-related emergencies; and challenging conversations. All residents completed pre-and post-simulation surveys reporting confidence levels. Changes in confidence were analyzed using paired t tests and differences between junior and senior residents' confidence using ANOVA. Eleven residents participated in 2 focus groups. Transcripts were analyzed using a constant comparative model to identify contexts, mechanisms, outcomes, and the relationship between these realist categories. Key themes were extracted using generic theme analysis. Results Aggregated survey data demonstrated statistically significant improvements in self-reported confidence for 7 of 8 proposed scenarios, with variations in confidence outcomes between junior and senior residents. Four themes emerged: (1) How Simulations Facilitate Learning, (2) The Role of Pre-simulation Instructions, (3) Factors Facilitating Confidence, (4) Positive Effects of Interdisciplinary Involvement. Conclusions This study identifies possible mechanisms for residents' self-reported improvements in learning and confidence, which may help programs tailor interventions. Furthermore, this study suggests there may be benefits to interdisciplinary simulations, with self-reported outcomes of improved collaboration and safety planning.

Microcystic adnexal carcinoma is a rare cutaneous neoplasm believed to arise from pluripotent keratinocytes capable of adnexal differentiation. Due to its insidious growth and appearance, diagnosis is often delayed. A deep incisional or excisional biopsy for histopathology is the gold standard for diagnosis. Different treatment modalities have been described in the literature, including the Mohs micrographic surgery, standard excision, radiation, chemotherapy, and observation. Currently, Mohs remains the treatment of choice. We present a unique case of a 12-month history of an extensive progressive centrofacial cutaneous induration diagnosed as microcystic adnexal carcinoma in an 83-year-old female. Due to the extensive nature of the tumor, she received radiation therapy and continues to receive ongoing assessment with no evidence of clinical recurrence at 2-year post-treatment including negative scouting biopsies. To date, there is no consensus on the optimal treatment for microcystic adnexal carcinoma.
