The health and well-being of Australia's future medical doctors: protocol for a 5-year observational cohort study of medical trainees.

INTRODUCTION: Clinical training in the undergraduate medical course places multiple stressors on trainees, which have been held to lead to heightened distress, depression, suicide, substance misuse/abuse and poor mental health outcomes. To date, evidence for morbidity in trainees is largely derived from cross-sectional survey-based research. This limits the accuracy of estimates and the extent to which predispositional vulnerabilities (biological and/or psychological), contextual triggers and longer-term consequences can be validly identified. Longitudinal clinical assessments embedded within a biopsychosocial framework are needed before effective preventative and treatment strategies can be put in place. METHODS AND ANALYSIS: This study is an observational longitudinal cohort study of 330 students enrolled in the undergraduate medicine course at the University of New South Wales (UNSW) Sydney, Australia. Students will be recruited in their fourth year of study and undergo annual assessments for 4 consecutive years as they progress through increasingly demanding clinical training, including internship. Assessments will include clinical interviews for psychiatric morbidity, and self-report questionnaires to obtain health, psychosocial, performance and functioning information. Objective measures of cognitive performance, sleep/activity patterns as well as autonomic and immune function (via peripheral blood samples) will be obtained. These data will be used to determine the prevalence, incidence and severity of mental disorder, elucidate contextual and biological triggers and mechanisms underpinning psychopathology and examine the impact of psychopathology on performance and professional functioning. ETHICS AND DISSEMINATION: Ethics approval has been granted by the UNSW human research ethics committee (reference HC16340). The findings will be disseminated through peer-reviewed publications and conference presentations, and distributed to key stakeholders within the medical education sector. The outcomes will also inform targeted preventative and treatment strategies to enhance stress resilience in trainee doctors.

A Longitudinal Study of Adjustment Disorder After Trauma Exposure.

OBJECTIVE: Adjustment disorder has been recategorized as a trauma- and stressor-related disorder in DSM-5. The aim of this study was to determine the prevalence of adjustment disorder in the first 12 months after severe injury; to determine whether adjustment disorder was a less severe disorder compared with other disorders in terms of disability and quality of life; to investigate the trajectory of adjustment disorder; and to examine whether the subtypes described in DSM-5 are distinguishable. METHOD: In a multisite, cohort study, injury patients were assessed during hospitalization and at 3 and 12 months postinjury (N=826). Structured clinical interviews were used to assess affective, anxiety, and substance use disorders, and self-report measures of disability, anxiety, depression, and quality of life were administered. RESULTS: The prevalence of adjustment disorder was 19% at 3 months and 16% at 12 months. Participants with adjustment disorder reported worse outcomes relative to those with no psychiatric diagnosis but better outcomes compared with those diagnosed with other psychiatric disorders. Participants with adjustment disorder at 3 months postinjury were significantly more likely to meet criteria for a psychiatric disorder at 12 months (odds ratio=2.67, 95% CI=1.59-4.49). Latent-profile analysis identified a three-class model that was based on symptom severity, not the subtypes identified by DSM-5. CONCLUSIONS: Recategorization of adjustment disorder into the trauma- and stressor-related disorders is supported by this study. However, further description of the phenomenology of the disorder is required.
