Treatment with β-Blockers and Incidence of Post-Traumatic Stress Disorder After Cardiac Surgery: A Prospective Observational Study

OBJECTIVE The aim was to investigate perioperative factors associated with the development of post-traumatic stress disorder (PTSD) in patients who underwent cardiac surgery. DESIGN Prospective observational study. SETTING Single academic center. PARTICIPANTS One hundred twenty-eight consecutive patients scheduled for elective cardiac surgery with cardiopulmonary bypass. INTERVENTIONS Patients were interviewed within the surgical unit 1 to 3 days before cardiac surgery. MEASUREMENTS AND MAIN RESULTS Six months after surgery, participants were mailed the modified version of the Posttraumatic Stress Symptom Inventory 10. Of the 71 patients who completed the questionnaire and mailed it back at follow-up, 14 (19.7%) received a diagnosis of PTSD. Seven of 13 female patients who were not treated with β-blockers received a diagnosis of PTSD compared with 0 of 12 who were treated with β-blockers (p = 0.005, Fisher exact test). In a general linear model, including sex and β-blocker treatment as predictors, the Posttraumatic Stress Symptom Inventory 10 score was significantly predicted by β-blockade (F = 4.74, p = 0.033), with a significant interaction between sex and β-blockade (F = 9.72, p = 0.003). CONCLUSIONS These findings suggest that the use of β-blockers might be protective against the development of PTSD in women after cardiac surgery.

Treatment decision-making capacity in non-consensual psychiatric treatment: a multicentre study

AIMS To evaluate treatment decision-making capacity (DMC) to consent to psychiatric treatment in involuntarily committed patients and to further investigate possible associations with clinical and socio-demographic characteristics of patients. METHODS 131 involuntarily hospitalised patients were recruited in three university hospitals. Mental capacity to consent to treatment was measured with the MacArthur Competence Assessment Tool for Treatment (MacCAT-T); psychiatric symptoms severity (Brief Psychiatric Rating Scale, BPRS-E) and cognitive functioning (Mini Mental State Examination, MMSE) were also assessed. RESULTS Mental capacity ratings for the 131 involuntarily hospitalised patients showed that patients affected by bipolar disorders (BD) scored generally better than those affected by schizophrenia spectrum disorders (SSD) in MacCAT-T appreciation (p < 0.05) and reasoning (p < 0.01). Positive symptoms were associated with poorer capacity to appreciate (r = -0.24; p < 0.01) and reason (r = -0.27; p < 0.01) about ones own treatment. Negative symptoms were associated with poorer understanding of treatment (r = -0.23; p < 0.01). Poorer cognitive functioning, as measured by MMSE, negatively affected MacCAT-T understanding in patients affected by SSD, but not in those affected by BD (SSD r = 0.37; p < 0.01; BD r = -0.01; p = 0.9). Poorer MacCAT-T reasoning was associated with more manic symptoms in the BD group of patients but not in the SSD group (BD r = -0.32; p < 0.05; SSD r = 0.03; p = 0.8). Twenty-two per cent (n = 29) of the 131 recruited patients showed high treatment DMC as defined by having scored higher than 75% of understanding, appreciating and reasoning MacCAT-T subscales maximum sores and 2 at expressing a choice. The remaining involuntarily hospitalised patients where considered to have low treatment DMC. Chi-squared disclosed that 32% of BD patients had high treatment DMC compared with 9% of SSD patients (p < 0.001). CONCLUSIONS Treatment DMC can be routinely assessed in non-consensual psychiatric settings by the MacCAT-T, as is the case of other clinical variables. Such approach can lead to the identification of patients with high treatment DMC, thus drawing attention to possible dichotomy between legal and clinical status.

2273 – Attachment style and posttraumatic stress disorder after cardiac surgery

Introduction Cardiac surgery with cardiopulmonary bypass represents a severe source of stress and has been reported to be associated to the development of Posttraumatic Stress Disorder (PTSD). This disorder leads to a significant disability that might greatly decrease the benefits of surgery. Research rarely focused on the role of attachment styles in the development of PTSD, and no studies addressed this issue in patients undergoing cardiac surgery. Objectives To assess the influence of attachment styles on the development of PTSD. Aims The identification of specific personological traits predictive of the development of PTSD. Methods Participants were recruited among patients scheduled for elective cardiac surgery with cardiopulmonary bypass and evaluated through a) Experiences in Close Relationships (ECR) b) Post-traumatic 10 Stress Symptom Inventory - Modified (PTSS-10) c) Perceived Stress Scale (PSS). Six months after surgery, participants were mailed the PTSS-10 and the PSS. Multiple logistic regression analysis was performed with PTSD as dependent variable, and attachment-related avoidance and anxiety, sex, age and perceived stress as independent variables. Results One hundred twenty-one patients (94% of candidates for elective cardiac surgery who met study inclusion criteria) underwent surgery; 61(59%) were assessed after 6 months. Fourteen subjects (19.7%) scored ≥35 on the PTSS-10 at followup and were considered as having a probable diagnosis of PTSD. Attachment related avoidance at baseline predicted the development of PTSD at follow-up (p Conclusions Subjects endorsing the avoidant attachment style are more likely to develop PTSD after cardiac surgery.

Free will, neuroscience, and choice: towards a decisional capacity model for insanity defense evaluations

Free will has often been considered central to criminal responsibility. Yet, the concept of free will is also difficult to define and operationalize, and, moreover, it is intensely debated. In particular, the very existence of free will has been denied based on recent neuroscience findings. This debate has significant implications on those fields in which the link between free will and behaviour is the main focus of interest, such as forensic psychiatry. In fact, a tension is often experienced between the centrality of the notion of free will on the one hand, and its controversial status on the other. This tension needs to be addressed, especially in forensic psychiatry, since it is relevant for actual assessments of legal insanity. In the present paper we will try to operationalize “free will” using a fourpartite decision-making capacity model, which can be used in forensic assessment of insanity. We will describe its advantages and application to guide mental insanity assessments. Whereas free will is often considered problematic from a neuroscience perspective, this model, we argue, is compatible with neuroscience; moreover, evaluations using this model can also be informed and strengthened by neuroscientific findings, for example regarding inhibitory control.
