Telephone Assessment of Suicidal Risk at Prehospital Emergency Medical Services: A Direct Comparison with Face-to-Face Evaluation at Psychiatric Emergency Service.

OBJECTIVE: Assessment of suicidal risk is one of the most challenging tasks faced by health professionals, notably in emergency care. We compared telephone suicide risk assessment at prehospital Emergency Medical Services Dispatch Center (EMS-DC), with subsequent face-to-face evaluation at Psychiatric Emergency Service (PES), using French national Risk-Urgency-Danger standards (RUD). METHOD: Data were collected for all suicidal adult patients (N = 80) who were addressed by EMS-DC to PES between December 2018 and August 2019 and benefited from RUD assessment at both services. Suicidal risk was given a score of 1, 2, 3 or 4, in order of severity. RESULTS: Mean of the differences between the RUD score at EMS-DC and PES was -0.825 (SD = 1.19), and was found to be significant (p < 0.01). The average time between RUD assessments was 420 min (SD = 448) and was negatively correlated with the difference in the RUD score (r = -0.295, p = 0.008). Associated suicide attempt increased the odds of a decrease in the RUD score (OR = 2.989; 95% CI = 1.141-8.069; p < 0.05). CONCLUSIONS: Telephone evaluation of suicidal risk using RUD at EMS-DC yielded moderately higher scores than those obtained by a subsequent face-to face evaluation at PES, with this difference partially explained by the time between assessments, and by clinical and contextual factors.

Direct medical cost of bipolar disorder: Insights from the FACE-BD longitudinal cohort.

BACKGROUND: Bipolar disorder (BD) is a severe chronic psychiatric disorder affecting 0.5 to 1% of the population worldwide. To date, most studies have estimated the cost of BD via information sourced from insurance claims with limited information on clinical characteristics and course of BD. The aims of this study are (i) to estimate the direct healthcare cost associated with BD and to identify contributing factors and (ii) to study the evolution of cost during a two-year follow-up period. METHOD: We analyzed a sample of 1116 individuals with BD included in the Advanced Centers of Expertise in Bipolar Disorder cohort. We estimated the direct healthcare cost per year and per patient, and we identified the clinical features of patients with BD associated with higher direct healthcare costs. In a subsample of patients followed up for two years centers of expertise for BD, we studied the evolution of direct healthcare cost. RESULTS: The average cost of bipolar disorder was € 6910 per year and per patient. Clinical features of BD, sociodemographic characteristics, and associated addiction were associated with higher direct healthcare costs. In the subsample of patients followed-up for two years, direct healthcare cost dropped by more than 50%, strongly suggesting the beneficial effect of specialized care organization. LIMITATION: We did not estimate indirect healthcare and intangible costs. CONCLUSION: Our study investigates the cost of BD and its evolution in a deeply phenotyped longitudinal sample. Cost-utility and cost-effectiveness analyses are required to inform resource allocation decisions and to promote innovative healthcare organizations.

Reconsideration of the factorial structure of the Barratt Impulsiveness Scale (BIS-11): Assessment of impulsivity in a large population of euthymic bipolar patients.

BACKGROUND: Impulsivity is commonly assessed using the Barratt Impulsiveness Scale (BIS-11). Some studies challenged the reliability of its three dimensional structure and proposed a bi-dimensional structure. METHODS: The psychometric reliability of the BIS-11 scale was studied in a sample of 580 euthymic bipolar patients. An alternative structure of the scale was conceived, using confirmatory factorial analysis (CFA) in the first half (N = 290) and cross-validated in the second half of our sample. Associations between the newly defined shortened scale and predefined clinical variables were computed. RESULTS: The original three dimensional structure did not fit in our sample according to statistical criteria in CFA. A 12 items Impulsivity Scale (IS-12) was designed with strong indices of fitting in the first half of our sample and replicated in the second half of our sample. The IS-12 evidences two dimensions: "behavioral impulsivity" and "cognitive impulsivity". Associations between "behavioral impulsivity" and both presence of past suicide attempts and number of suicide attempts were observed. Substance misuse was strongly associated with both subscores of the new scale. LIMITATIONS: The rating of the items assessing the two dimensions of the IS-12 is reversed. The population is restricted to euthymic bipolar patients. CONCLUSIONS: The Impulsivity Scale assesses two distinct dimensions named behavioral and cognitive impulsivity. It was reliable and valid in our sample and associated with the existence of suicidal behavior and with substance misuse (alcohol and cannabis). Further studies are needed to demonstrate its predictive validity.

Prevalence of and Risk Factors for Extrapyramidal Side Effects of Antipsychotics: Results From the National FACE-SZ Cohort.

BACKGROUND: Extrapyramidal side effects (EPS) have been identified as a complication of antipsychotic treatment. Previous meta-analyses have investigated EPS prevalence and risk factors in randomized clinical trials with highly selected patients, but studies in real-world schizophrenia are missing. OBJECTIVE: To examine the prevalence and clinical correlates associated with EPS in a nonselected national multicenter sample of stabilized patients with schizophrenia. METHODS: Between 2010 and 2016, patients suffering from schizophrenia (DSM-IV-TR criteria) were recruited through the FondaMental Academic Centers of Expertise for Schizophrenia (FACE-SZ) network and data were collected during a comprehensive 1-day-long standardized evaluation. The Simpson-Angus Scale and the Abnormal Involuntary Movement Scale were used to assess drug-induced parkinsonism (DIP) and tardive dyskinesia, respectively. RESULTS: The overall prevalence of DIP and tardive dyskinesia was 13.2% and 8.3%, respectively, in this community-dwelling sample of 674 patients. DIP was associated with negative symptoms (Positive and Negative Syndrome Scale [PANSS] subscore) (adjusted odds ratio [aOR] = 1.102, P < .001), first-generation antipsychotic prescription (aOR = 2.038, P = .047), and anticholinergic drug administration (aOR = 2.103, P = .017) independently of sex, age, disorganization (PANSS disorganized factor), and antipsychotic polytherapy. Tardive dyskinesia was associated with PANSS disorganized factor (aOR = 1.103, P = .049) independently of sex, age, negative symptoms, excitation, first-generation antipsychotic prescription, and benzodiazepine and anticholinergic drug administration. CONCLUSIONS: Our results indicate the high prevalence of EPS in a nonselected community-dwelling clinically stable sample of outpatients with schizophrenia. In the monitoring of antipsychotic treatment, EPS should be systematically evaluated, especially when negative symptoms and disorganization or cognitive alteration are present. Monotherapy with a second-generation antipsychotic should be preferentially initiated for patients with these side effects.

Mediation analysis of severity of needs, service performance and outcomes for patients with mental disorders.

BACKGROUND: Needs and service performance assessment are key components in improving recovery among individuals with mental disorders. AIMS: To test the role of service performance as a mediating factor between severity of patients' needs and outcomes. METHOD: A total of 339 adults with mental disorders were interviewed. A mediation analysis between severity of needs, service performance (adequacy of help, continuity of care and recovery orientation of services) and outcomes (personal recovery and quality of life) was carried out using structural equation modelling. RESULTS: The structural equation model provided a good fit with the data. An increase in needs was associated with lower service performance and worse outcomes, whereas higher service performance was associated with better outcomes. Service performance partially mediated the effect of patient needs on outcomes. CONCLUSIONS: Poorer service performance has a negative impact on outcomes for patients with the highest needs. Ensuring more efficient services for patients with high needs may help improve their recovery and quality of life.

Quantitative assessment of attribution of intentions to others in schizophrenia using an ecological video-based task: a comparison with manic and depressed patients.

Schizophrenia is characterized by the impairment of several facets of social cognition. This has been demonstrated in numerous studies that focused on specific aspects of social cognition such as the attribution of intentions, emotions, or false beliefs to others. However, most of these studies relied on complex verbal descriptions or impoverished social stimuli. In the present study, we evaluated a new task (Versailles-Situational Intention Reading, V-SIR) that is based on video excerpts depicting complex real-life scenes of social interactions. Subjects were required to rate the probabilities of several affirmations of the intentions of one of the characters. The V-SIR task was administered to schizophrenic patients (N=15), depressed patients (N=12), manic patients (N=15), and healthy controls (N=15). The performance of schizophrenic patients was significantly impaired in comparison to healthy and depressed subjects. There was a trend toward a significant difference between schizophrenic and manic patients. Manic patients also demonstrated impaired performance relative to healthy subjects. Schizophrenic patients' V-SIR scores were significantly correlated with their scores on another attribution of intentions task that used comic strips. These results show that tasks based on more ecological stimuli are powerful enough to detect theory-of-mind abnormalities in pathological populations such as schizophrenic patients.
