RESUMO

BACKGROUND: Stigma resistance (SR) is defined as one's ability to deflect or challenge stigmatizing beliefs. SR is positively associated with patient's outcomes in serious mental illness (SMI). SR appears as a promising target for psychiatric rehabilitation as it might facilitate personal recovery. OBJECTIVES: The objectives of the present study are: (i) to assess the frequency of SR in a multicentric non-selected psychiatric rehabilitation SMI sample; (ii) to investigate the correlates of high SR. METHODS: A total of 693 outpatients with SMI were recruited from the French National Centers of Reference for Psychiatric Rehabilitation cohort (REHABase). Evaluation included standardized scales for clinical severity, quality of life, satisfaction with life, wellbeing, and personal recovery and a large cognitive battery. SR was measured using internalized stigma of mental illness - SR subscale. RESULTS: Elevated SR was associated with a preserved executive functioning, a lower insight into illness and all recovery-related outcomes in the univariate analyses. In the multivariate analysis adjusted by age, gender and self-stigma, elevated SR was best predicted by the later stages of personal recovery [rebuilding; p = 0.004, OR = 2.89 (1.36-4.88); growth; p = 0.005, OR = 2.79 (1.30-4.43)). No moderating effects of age and education were found. CONCLUSION: The present study has indicated the importance of addressing SR in patients enrolled in psychiatric rehabilitation. Recovery-oriented psychoeducation, metacognitive therapies and family interventions might improve SR and protect against insight-related depression. The effectiveness of psychiatric rehabilitation on SR and the potential mediating effects of changes in SR on treatment outcomes should be further investigated in longitudinal studies.

RESUMO

OBJECTIVE: The effectiveness of programs integrating trained and paid peer helpers on symptoms, quality of life and recovery of persons with bipolar disorder or schizophrenia is still poorly understood. The factors influencing the integration of peer helpers into healthcare teams are also poorly understood. METHOD: A systematic review of the literature was performed. We systematically searched multiple electronic databases for articles: (i) exploring the effectiveness of the intervention of trained and paid peer helpers in bipolar disorder and schizophrenia (ii) reporting barriers and facilitators to the integration of peer helpers. RESULTS: Forty-eight articles were included, 24 on the effectiveness of the intervention of peer helpers, 18 on barriers and 13 on facilitators to the integration of peer helpers in health teams. Of them, 25 were based upon qualitative methods (7 concerning the effectiveness of the intervention of peer helpers, 14 the barriers and 7 the facilitators to their integration); 23 were based upon quantitative methods (9 studies focused on the effectiveness of peer helper intervention, 2 on barriers and 6 on integration facilitators). The 23 quantitative studies included 8 randomized controlled trials. CONCLUSION: In spite of their heterogeneity, the results suggest that that interventions of peer helpers have a positive impact on the recovery, quality of life, social functioning, physical health and clinical outcome of persons with bipolar disorder or schizophrenia. The results also showed that the integration of peer helpers is favored by caregivers' awareness about the role of peer helpers and knowledge about the recovery model. The results highlight the need for peer helpers to have a well-defined role and to be supervised, preferably by another peer helper.

RESUMO

OBJECTIVE: Increasing users' knowledge about the expected benefits and risks of clozapine may contribute to the initiation and maintenance of clozapine in persons with treatment-resistant schizophrenia (TRS). The objective was to identify the educational needs of clozapine users and the interventions aimed at addressing these needs. METHOD: We systematically searched multiple electronic databases for articles: (i) exploring educational needs of clozapine users and of their relatives; and (ii) reporting educational interventions aimed at addressing these needs. Data were synthesized narratively. RESULTS: A total of 30 articles published from 1990 to 2019 in 8 countries fulfilled our inclusion criteria. As most studies on educational needs (n = 18) were carried out in persons already taking clozapine, educational needs of TRS patients who were candidates for clozapine treatment are not well documented. Users' level of knowledge about clozapine was often poor, especially about adverse effects or interactions with other substances, with a poor retention of information delivered at treatment initiation. Among 12 studies reporting educational interventions in clozapine users, five provided quantitative outcomes. Their findings suggest that structured educational programmes may contribute to promote clozapine initiation and to improve users' knowledge about this drug. CONCLUSION: The literature is sparse on structured educational interventions about clozapine, and only one randomized controlled trial was identified. A promising strategy emerging from this review may be staging educational interventions according to the evolving needs of persons with TRS before clozapine use, at initiation and during maintenance treatment.

RESUMO

BACKGROUND: Real-World Data (RWD) studies provide important insights in disease epidemiology, in real clinical populations, with long follow-up periods. The aim of the present study was to describe the epidemiology of schizophrenia spectrum disorders (SD) during an 8-year period in Spain. METHODS: A retrospective cohort of subjects aged 15 to 64 years was followed-up using electronic healthcare databases of the Valencia region (2008-2015). SD cases included outpatient and inpatient settings (ICD 9 codes 295.XX). Prevalence of SD was assessed. Incidence rate (IR) in the subpopulation aged between 15 and 34 years was also provided. Healthcare utilization (HCU) rates, including outpatient, specialists, hospitalizations and antipsychotic dispensations were estimated. RESULTS: The cohort included 3,976,071 subjects; 24,749 of them had a prevalent diagnosis of SD. The overall prevalence for SD was 6.2 per 1000 persons. SD were 76% more prevalent in men than women. IR in the subpopulation aged between 15 and 34 years was 50.25 per 100,000 persons years and was more than 2 times higher for men than for women. 83.4% of the overall outpatient visits from the cohort of patients were related to SD. The 21,095 overall hospitalizations with the SD code resulted in 286,139 days of hospitalization, with a median of 4 days (IQR: 1.6-9.2) per person-year. 93.2% of subjects diagnosed with SD were ever treated with some antipsychotic drug during the study period, and 70% of the patients were ever treated with antipsychotic polypharmacy. CONCLUSIONS: This large population-based study using RWD provides novel and recent information SD in a southern European country. The prevalence and IR of SD showed is greater than previously published and higher in men than in women. The fact of having used a large arsenal of electronic data (including outpatient and inpatient) for 8 years may have influenced. SD represents high burden and healthcare utilization. Contrary to guidelines recommendations the majority of patients were ever treated with antipsychotic polypharmacy.

RESUMO

This study explored in a non-clinical sample whether metacognitive awareness assessments measured during ("on line") and after ("end line") a neuropsychological task lead to comparable results in tests exploring basic-level or high-level cognitive functions. Short-term memory and working memory tests (forward and backward digit recall of the WAIS-III) were used to measure basic-level cognitive function. A social cognition test, the French adaptation of the Faces Test, was used to assess high-level cognitive function through recognition of facial emotions. For these two tests, we explored "on line" metacognitive awareness using a method based upon Koriat and Goldsmith's protocol. After each answer, participants were asked to rate their level of confidence in the correctness of their response. Persons had also to rate their confidence in their answer only once, at the end of the neuropsychological test, in order to explore "end line" metacognitive awareness. They were then asked "do you feel you have passed this test?" and had to rate their feeling of success on a 4-point Likert-type scale ("no", "rather not", "rather yes", "yes"). No association was found between "on line" and "end line" metacognitive awareness scores on memory tests. Poor "end line" metacognitive awareness was associated with lower "on line" metacognitive awareness score in the social cognition test. It might be of interest to assess both "on line" and "end line" metacognitive awareness in persons with schizophrenia to better take into accounts the multi-faceted structure of metacognition.

RESUMO

CONTEXT: Electro-convulsive therapy (ECT) is the most effective treatment for treatment resistant mood disorders and catatonia. ECT also appears to be an effective treatment in combination with clozapine in the context of treatment resistant schizophrenia spectrum disorders. Although increasingly codified (guidelines on indications, contraindications, methods of implementation), the practice of ECT still lacks consensual protocols. The concomitant use of psychotropic and/or non-psychotropic medication is a common situation when ECT treatment is considered. To our knowledge, there is to date no summary of studies or case reports in France, nor any proposal for guidelines concerning the management of medication of the patient to whom ECT sessions are offered. Indeed, several particularities must be considered. This article proposes to specify for each pharmacological class the possible interaction between ECT and medication. A first section of this article will be devoted to non-psychotropic treatments, and a second section to psychotropic treatments. A practical summary table is also provided. METHOD: A review of the literature was conducted including all articles published prior to January 2019 referenced in Pub Med database, combining research with Medical Subject Headings "Electroconvulsive Therapy" and each following pharmacological class: "Cardiovascular Agents" "Bronchodilator Agents" "Bronchoconstrictor Agents" "Theophylline" "Anticoagulants" "Hypoglycemic Agents" "Insulin" "Potassium" "Benzodiazepines" "Valproic Acid" "Carbamazepine" "Lamotrigine" "Lithium" "Antidepressive Agents" "Antipsychotic Agents". RESULTS: After reading the titles, abstracts and whole articles, then searching for additional articles in the references, 50 articles were selected. A summary table summarizing the main risks and proposing a course of action has been produced. DISCUSSION: It is essential to take into account the specificity and the different physiological mechanisms involved in the ECT treatment in order to adjust the associated pharmacological treatments. The prescription for each molecule should be reviewed when ECT treatment is initiated.

RESUMO

The recent COVID-19 pandemic has led to major organisational changes in health care settings, especially in psychiatric hospitals. We conducted a national online survey to assess the evolution of electroconvulsive therapy (ECT) in the different centres practicing this treatment. 65 responses from all over France were analysed. More than 90 % of the centres practising ECT experienced a decrease in their activity. Half of the centres experienced a total cessation of activity and 25 % of the centres experienced a decrease of more than half of their usual activity. Post-pandemic COVID-19 psychiatric care is expected to be difficult. It is essential not to add to this difficulty the complications, often serious, that will be associated with delaying or stopping the practice of ECT. It will also be necessary to remain vigilant with regard to the specific neuropsychiatric consequences that will follow the pandemic.

RESUMO

The COVID-19 pandemic has had major consequences for the organization of care. In France and around the world, centers practicing electroconvulsive therapy (ECT) have seen their activity decrease, or even stop for many reasons. In this context, maintaining or resuming this essential therapeutic activity for many patients suffering from psychiatric disorders requires material, human and logistical adaptations that should be supervised. The objective of this collective and national work is to offer simple recommendations that can be applied immediately by any healthcare establishment, public or private, practicing ECT. They are the result of feedback from multiprofessional and inter-establishment experiences. Declined in three stages, these recommendations are accompanied by a practical sheet which describes in detail the necessary conditions and prerequisites for any resumption of ECT activity.

RESUMO

OBJECTIVES: Video games and virtual reality have recently become used by clinicians for training or information media or as therapeutic tools. The purpose is to review the use of these technologies for therapy destined for schizophrenia patients. METHODS: We conducted a review in October 2016 using Pubmed, Scopus and PsychInfo using the following Medical Subject Headings (MESH): "video games", "virtual reality" and "therapy, computer-assisted/methods", each associated with "schizophrenia". Papers were included in the review if: (a) they were published in an English, Spanish or French-language peer-reviewed journal, (b) the study enrolled patients with schizophrenia or schizo-affective disorder, (c) the patients used a therapeutic video game or therapeutic virtual reality device. RESULTS: Eighteen publications were included. The devices studied are mainly therapeutic software developed specifically for therapeutic care. They can be classified according to their therapeutic objectives. These targets corresponded to objectives of psychosocial rehabilitation: improvement of residual symptomatology, cognitive remediation, remediation of cognition and social skills, improvement of everyday life activities, support for occupational integration. Very different devices were proposed. Some researchers analysed programs developed specifically for patients with schizophrenia, while others were interested in the impact of commercial games. Most of the studies were recent, preliminary and European. The impact of these devices was globally positive, particularly concerning cognitive functions. CONCLUSIONS: Computer-assisted therapy, video games and virtual reality cannot replace usual care but could be used as adjunctive therapy. However, recommending their use seems premature because of the recent and preliminary character of most studies. Moreover, a link is still lacking between this field of research in psychiatry and other fields of research, particularly game studies. Finally, it might be interesting to analyse more precisely the neuropsychological impact of existing commercial games which could potentially be useful for psychosocial rehabilitation.

RESUMO

This article analyzes whether psychiatric disorders can be considered different from non-psychiatric disorders on a nosologic or semiologic point of view. The supposed difference between psychiatric and non-psychiatric disorders relates to the fact that the individuation of psychiatric disorders seems more complex than for non-psychiatric disorders. This individuation process can be related to nosologic and semiologic considerations. The first part of the article analyzes whether the ways of constructing classifications of psychiatric disorders are different than for non-psychiatric disorders. The ways of establishing the boundaries between the normal and the pathologic, and of classifying the signs and symptoms in different categories of disorder, are analyzed. Rather than highlighting the specificity of psychiatric disorders, nosologic investigation reveals conceptual notions that apply to the entire field of medicine when we seek to establish the boundaries between the normal and the pathologic and between different disorders. Psychiatry is thus very important in medicine because it exemplifies the inherent problem of the construction of cognitive schemes imposed on clinical and scientific medical information to delineate a classification of disorders and increase its comprehensibility and utility. The second part of this article assesses whether the clinical manifestations of psychiatric disorders (semiology) are specific to the point that they are entities that are different from non-psychiatric disorders. The attribution of clinical manifestations in the different classifications (Research Diagnostic Criteria, Diagnostic Statistic Manual, Research Domain Criteria) is analyzed. Then the two principal models on signs and symptoms, i.e. the latent variable model and the causal network model, are assessed. Unlike nosologic investigation, semiologic analysis is able to reveal specific psychiatric features in a patient. The challenge, therefore, is to better define and classify signs and symptoms in psychiatry based on a dual and mutually interactive biological and psychological perspective, and to incorporate semiologic psychiatry into an integrative, multilevel and multisystem brain and cognitive approach.

RESUMO

Psychiatry as a discipline should no longer be grounded in the dualistic opposition between organic and mental disorders. This non-dualistic position refusing the partition along functional versus organic lines is in line with Jean Delay, and with Robert Spitzer who wanted to include in the definition of mental disorder discussed by the DSM-III task force the statement that "mental disorders are a subset of medical disorders". However, it is interesting to note that Spitzer and colleagues ingeniously introduced the definition of "mental disorder" in the DSM-III in the following statement: "there is no satisfactory definition that specifies precise boundaries for the concept "mental disorder" (also true for such concepts as physical disorder and mental and physical health)". Indeed, as for "mental disorders", it is as difficult to define what they are as it is to define what constitutes a "physical disorder". The problem is not the words "mental" or "organic" but the word "disorder". In this line, Wakefield has proposed a useful "harmful dysfunction" analysis of mental disorder. They raise the issue of the dualistic opposition between organic and mental disorders, and situate the debate rather between the biological/physiological and the social. The paper provides a brief analysis of this shift on the question of what is a mental disorder, and demonstrates that a mental disorder is not more "organic" than any other medical condition. While establishing a dichotomy between organic and psychiatry is no longer intellectually tenable, the solution is not to reduce psychiatric and non-psychiatric disorders to the level of "organic disorders" but rather to continue to adopt both a critical and clinically pertinent approach to what constitutes a "disorder" in medicine.

RESUMO

OBJECTIVES: The first objective of this article is to summarize the history of electroconvulsive therapy (ECT) in psychiatry in order to highlight the transition from clinical level of evidence based on phenomenological descriptions to controlled trial establishing causal relationship. The second objective is to apply the criteria of causation for ECT, to focus on the dose-effect relationship criteria, and thus to analyze the conditions of application of these criteria for ECT. METHODS: A literature review exploring the use of electricity, ECT and electroencephalography (EEG) in psychiatry was conducted. The publications were identified from the Pubmed and GoogleScholar electronic databases. The scientific literature search of international articles was performed in July 2016. RESULTS: In 1784, a Royal commission established in France by King Louis XVI tested Mesmer's claims concerning animal magnetism. By doing that, the commission, including such prominent scientists as the chemist Anton Lavoisier and the scientist and researcher on electricity and therapeutics Benjamin Franklin, played a central role in establishing the criteria needed to assess the level of evidence of electrical therapeutics in psychiatry. Surprisingly, it is possible to identify the classical Bradford Hill criteria of causation in the report of the commission, except the dose-effect relationship criteria. Since then, it has been conducted blinded randomized controlled trials that confirmed the effectiveness of ECT against ECT placebos for the treatment of psychiatric disorders. At present, the dose-effect relationship criteria can be analyzed through an EEG quality assessment of ECT-induced seizures. CONCLUSIONS: EEG quality assessment includes several indices: TSLOW (time to onset of seizure activity ≤5Hz, seconds), peak mid-ictal amplitude (mm), regularity (intensity or morphology of the seizure (0-6)), stereotypy (global seizure patterning, 0-3) and post-ictal suppression (0-3). A manual rating sheet is needed to score theses indices. Such manual rating with example of EEG segments recording is proposed in this article. Additional studies are needed to validate this manual, to better establish the dose-response relationship for the ECT, and thus strengthen the position of the EEG as a central element for clinical good practice for ECT.

RESUMO

The aim of this review of the literature is to summarize the state of the knowledge concerning the relationship between negative symptoms in schizophrenia, electrophysiology and electrotherapy. The scientific literature search of international articles was performed during August and September 2015 using the PubMed electronic database. We used the following MeSH terms: "Negative symptoms", "Schizophrenia", "Electrophysiology", "Neurophysiology", "EEG power", "Alpha rhythm", "Transcranial magnetic stimulation", "Transcranial direct current stimulation", "Electroconvulsive therapy", "Neurofeedback", "Vagus Nerve Stimulation", "Deep Brain Stimulation", and "State dependent". Negative symptoms in schizophrenia are associated with altered activity in prefrontal cortex in functional neuroimaging studies. This is in line with electrophysiological measurements that found a change in EEG spectral power in the alpha frequency band over prefrontal brain regions. The notion of functional hypofrontality has led to hypotheses that electrotherapy applied to the prefrontal cortex may be an effective treatment of negative symptoms in schizophrenia. Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) were used to increase cortical activity in schizophrenia and achieve a clinical effect on negative symptoms. Three meta-analyses confirmed, with a moderate effect size, that rTMS is an effective treatment option for negative symptoms in schizophrenia. The two subsequently published prospective multicenter studies, however, found opposite results from each other. Two randomized controlled studies suggested that tDCS is an effective treatment option for negative symptoms. There is no study on the efficacy of neurofeedback, vagal nerve stimulation or deep brain stimulation on negative symptoms in schizophrenia. Additional studies are needed to confirm the efficacy of rTMS and tDCS on negative symptoms in schizophrenia. Influencing factors, related to clinical and stimulation parameters, of rTMS and tDCS on negative symptoms should be better investigated. Effects related to electrophysiological brain activity of the patient, especially in the alpha band, during the stimulation should also be better investigated. The action of electrotherapy may be state dependent, and a better understanding of electrophysiological effects of electrotherapy techniques could enable their optimization.

RESUMO

Whereas metacognition is of great interest for neuropsychological practice, little is known about the impact of metacognitive questions during a neuropsychological assessment. This study explored the impact of measuring "on-line" metacognitive processes on neuropsychological performances in a non-clinical population. Participants were randomly assigned to a "standard" or a "metacognitive" neuropsychological test procedure. The "standard" procedure assessed executive functions (Modified Card Sorting Test), episodic memory ("Rappel libre Rappel indicé" 16), working memory (digit span test Wechsler Adult Intelligence Scale III) and social cognition (Faces Test). In the "metacognitive" procedure, two questions were added after each item of these tests to evaluate "on-line" metacognitive monitoring and control. Working memory performances were better and episodic memory performances lower in the "metacognitive" versus the "standard" procedure. No significant difference was found concerning executive functioning or social cognition. The assessment of "on-line" metacognition might improve working memory performances by enhancing concentration, and might impair episodic memory performances by acting as a distractor. These findings may have implications for the development of cognitive remediation programs.

RESUMO

OBJECTIVES: The aim of this review of the literature is to summarise the definitions of metacognition, the measurement tools, the results of studies investigating metacognition in persons with schizophrenia and the therapeutic perspectives. METHOD: This review is based upon a selection of articles identified using a PubMed search containing the terms "schizophrenia" and "metacognition". RESULTS: Cognitive deficits are present in 75 to 85% of persons with schizophrenia. According to the disability model of the World Health Organization, these cognitive deficits have an impact on social functioning, community integration and quality of life. However, heterogeneous results have been obtained by studies exploring the functional impact of cognitive deficits, suggesting that there is no direct relationship between these two characteristics. One possible explanation is that subjective factors, notably metacognition, may play an intermediate role moderating the link between cognitive deficits and functional impairment. Metacognition is defined as the evaluation and regulation of its own cognitive processes. The evaluation (or monitoring) monitors the accuracy and reliability of the cognitive task performance. Regulation (or control) promotes behavioural adjustment. Studies carried out in persons with schizophrenia show that most of them experience deficits in metacognitive performance. These metacognitive deficits are thought to be a key barrier to functioning in schizophrenia. Measurement tools are classified into two types: "independent" measurement of the cognitive task and "on line" measurements performed during the cognitive task. The subjective scale to investigate cognition in schizophrenia (SSTIC) and the metacognitive assessment scale (MAS) are two examples of questionnaires measuring metacognition independently of the cognitive task. Online measurements assess the metacognitive "monitoring" by asking the subject to evaluate between 0 and 100% of his/her degree of confidence in his/her response to a question. The metacognitive "control" is assessed by asking the subject to validate his/her answer. Convergent findings are reported by studies exploring metacognitive persons in people with schizophrenia. Dissociation between metacognitive monitoring and metacognitive control has been reported. Regarding metamemory, which has been currently the most studied area, no difference is observed between persons with schizophrenia and controls with respect to the metamemory judgement. However, subgroups of persons with schizophrenia differ significantly from controls: they are over-confident in their response if it is incorrect and they estimate more frequently than the controls if they do not know when their answer is correct. The relationships between metacognitive and cognitive deficits are complex in persons with schizophrenia, with poor matching between subjective and objective deficits. Several studies have reported that metacognitive difficulties strongly interfere with social functioning. It has been suggested that metacognitive deficits more strongly predict community functioning in persons with schizophrenia than cognitive deficits. Metacognitive skills may hence be viewed as a key factor in translating cognitive performance skills in daily life. CONCLUSION: These data suggest that remediation programs specifically targeting metacognitive deficits have to be further developed.

Parenting is a central life experience that could promote recovery in people with Serious Mental Illness (SMI). It could also be challenging for parents with SMI and result in poor recovery-related outcomes. Parenting is often overlooked in psychiatric rehabilitation. The objectives of the present study were to identify the characteristics and needs for care of mothers and fathers with SMI enrolled in a multicentric non-selected psychiatric rehabilitation SMI sample. We consecutively recruited 1436 outpatients from the French National Centers of Reference for Psychiatric Rehabilitation cohort (REHABase). The evaluation included standardized scales for clinical severity, psychosocial function, quality of life and satisfaction with life, wellbeing, personal recovery and a broad cognitive battery. We found that parenting was associated to suicidal history in mothers and fathers with SMI. In the multivariate analysis, being mother was best explained by insight (p < 0.015, adjusted OR = 0.76 [0.59-0.90]), current age (p < 0.001, aOR = 1.13 [1.07-1.21]), education level (p = 0.008; aOR = 0.12 [0.02-0.53]) and family accommodation (p = 0.046, aOR = 0.19 [0.03-0.84]). Being father was best explained by suicidal history (p = 0.005, aOR = 3.85 [1.51-10.10]), marital status (in relationship, p < 0.001; aOR = 7.81 [2.73-23.84]), satisfaction with family relationships (p = 0.032, aOR = 1.22 [1.02-1.47]) and current age (p < 0.001, aOR = 1.16 [1.10-1.23]). In short, parenting was associated to increased history of suicide attempt in mothers and fathers with SMI. Mothers and fathers with SMI may have unique treatment needs relating to parenting and recovery-related outcomes. The implementation of interventions supporting the needs of parents with SMI in psychiatric rehabilitation services could improve parent and children outcomes.

RESUMO

INTRODUCTION: Hip fracture in the elderly is one of the most prevalent diagnoses in Orthopedic Surgery Departments. It has a great impact in medical, economic and social terms. Our objective is to analyze clinical impact of a co-management care model between orthopedic surgery and internal medicine departments for elderly patients admitted with hip fracture in a tertiary referral hospital. MATERIAL AND METHODS: Retrospective cohort study of patients older than 65 years old admitted with hip fracture between January 2005-August 2006 (HIST cohort) without a co-management care model, and between January 2008-August 2010 (COFRAC cohort) with a co-manEdadment care model. Analysis of demographic, clinical and surgery characteristics, complications incidence and mortality and re-admissions at 30 days was made. RESULTS: A total of 701 patients were included (471 HIST, 230 COFRAC). There were no differences in sex, gender, time to surgery, type of anesthesia and surgery, length of stay, ambulation at discharge and 30-days emergency room consultation, readmissions or mortality at 30 days. There were differences in identification of polypatological patients (16.8 vs. 24.4%, P=0.02), presence of osteoporosis (3.9 vs. 7.6%, P=0.03), motor deficit (3.5 vs. 8.8%, P=0.03), number of chronic drugs (3.7±2.5 vs. 4.3±3.2, P<0.01), diagnosis of delirium (15.6 vs. 20.9%, P=0.048), constipation (80.3 vs. 74.7%, p<0.001), monitoring of anemia (83.3 vs. 97.1%, P>0.01) and renal failure at discharge (44.5 vs. 97.3%, P<0.01) and hospital mortality (4.6 vs. 1.3%, P=0.02). CONCLUSIONS: Co-management for elderly patients admitted with hip fracture provides a better information about previously chronic conditions, a higher control of hospital complications and decreases hospital mortality.

RESUMO

BACKGROUND: Self-stigma is a major issue in serious mental illness (SMI) and is negatively associated with patient outcomes. Most studies have been conducted in schizophrenia (SZ). Less is known about self-stigma in other SMI and autism spectrum disorder (ASD). The objectives of this study are: (i) to assess the frequency of self-stigma in a multicentric nonselected psychiatric rehabilitation SMI and ASD sample; and (ii) to investigate the correlates of elevated self-stigma in different SMI conditions and in ASD. METHODS: A total of 738 SMI or ASD outpatients were recruited from the French National Centers of Reference for Psychiatric Rehabilitation cohort (REHABase). Evaluations included sociodemographic data, illness characteristics, and standardized scales for clinical severity, quality of life, satisfaction with life, wellbeing, personal recovery, a large cognitive battery, and daily functioning assessment. RESULTS: 31.2% of the total sample had elevated self-stigma. The highest prevalence (43.8%) was found in borderline personality disorder and the lowest (22.2%) in ASD. In the multivariate analysis, elevated self-stigma was best predicted by early stages of personal recovery (moratorium, p = 0.001, OR = 4.0 [1.78-8.98]; awareness, p = 0.011, OR = 2.87 [1.28-6.44]), history of suicide attempt (p = 0.001, OR = 2.27 [1.37-3.76]), insight (p = 0.002, OR = 1.22 [1.08-1.38]), wellbeing (p = 0.037, OR = 0.77 [0.60-0.98]), and satisfaction with interpersonal relationships (p < 0.001, OR = 0.85 [0.78-0.93]). CONCLUSIONS: The present study has confirmed the importance of addressing self-stigma in SMI and ASD patients enrolled in psychiatric rehabilitation. The effectiveness of psychiatric rehabilitation on self-stigma and the potential mediating effects of changes in self-stigma on treatment outcomes should be further investigated.
