RESUMO

Introduction: Functional neurological disorder (FND) presents motor, sensory, and cognitive symptoms characterized by clinical signs incongruent with known neurological disease. Together with other health professionals, like neurologists, psychiatrists can play an essential role in diagnosing and managing these disorders. Hence, understanding their opinion and clinical experience with FND is of utmost importance to catch potential educational needs and improve healthcare services for patients. This study aims at assessing the knowledge, opinion, and clinical approach of Italian psychiatrists to FND. Methods: Members of the Italian Society of Psychiatry completed a 14-item web-based survey investigating their approach to FND. Results. Overall, 174 questionnaires were completed. Our main findings suggest that Italian psychiatrists have a psychogenetic conceptualization of FND. "Conversion disorders", in fact, is the term most frequently used by Italian psychiatrists to refer to FND, thus implying a psychological etiology of these disorders. Congruently with this view, psychotherapy associated with pharmacological therapy is considered the most appropriate treatment by psychiatrists, while physiotherapy is an under-recognized treatment option for FND. Discussion: The present study highlights that a psychogenetic view of FND dominates among Italian psychiatrists. This could be due to out-of-date knowledge about the pathophysiology of this group of disorders. Promoting education about novel approaches to FND would be of crucial importance to improving care for patients suffering from this condition.

RESUMO

BACKGROUND: Internet-based cognitive behavioral therapy (iCBT) services for common mental health disorders have been found to be effective. There is a need for strategies that improve implementation in routine practice. One-size-fits-all strategies are likely to be ineffective. Tailored implementation is considered as a promising approach. The self-guided integrated theory-based Framework for intervention tailoring strategies toolkit (ItFits-toolkit) supports local implementers in developing tailored implementation strategies. Tailoring involves identifying local barriers; matching selected barriers to implementation strategies; developing an actionable work plan; and applying, monitoring, and adapting where necessary. OBJECTIVE: This study aimed to compare the effectiveness of the ItFits-toolkit with implementation-as-usual (IAU) in implementing iCBT services in 12 routine mental health care organizations in 9 countries in Europe and Australia. METHODS: A stepped-wedge cluster randomized trial design with repeated measures was applied. The trial period lasted 30 months. The primary outcome was the normalization of iCBT delivery by service providers (therapists, referrers, IT developers, and administrators), which was measured with the Normalization Measure Development as a proxy for implementation success. A 3-level linear mixed-effects modeling was applied to estimate the effects. iCBT service uptake (referral and treatment completion rates) and implementation effort (hours) were used as secondary outcomes. The perceived satisfaction (Client Satisfaction Questionnaire), usability (System Usability Scale), and impact of the ItFits-toolkit by implementers were used to assess the acceptability of the ItFits-toolkit. RESULTS: In total, 456 mental health service providers were included in this study. Compared with IAU, the ItFits-toolkit had a small positive statistically significant effect on normalization levels in service providers (mean 0.09, SD 0.04; P=.02; Cohen d=0.12). The uptake of iCBT by patients was similar to that of IAU. Implementers did not spend more time on implementation work when using the ItFits-toolkit and generally regarded the ItFits-toolkit as usable and were satisfied with it. CONCLUSIONS: The ItFits-toolkit performed better than the usual implementation activities in implementing iCBT services in routine practice. There is practical utility in the ItFits-toolkit for supporting implementers in developing and applying effective tailored implementation strategies. However, the effect on normalization levels among mental health service providers was small. These findings warrant modesty regarding the effectiveness of self-guided tailored implementation of iCBT services in routine practice.

RESUMO

We aimed to evaluate in a sample of outpatients with schizophrenia (SCZ) the effectiveness of a cognitive remediation (CR) program (through the use of the Cogpack software) [computer-assisted CR (CACR)] in addition to standard therapy on cognitive outcomes as compared with that in a control active group (CAG) and to highlight a possible effect on social cognition (SC), metacognition, symptomatology, and real-world functioning. Of the 66 subjects enrolled, 33 were allocated to CACR and 33 to the CAG. Twenty-three patients in the CACR group and 25 subjects in the CAG completed at least 80% of the 48 prescribed CACR sessions, performed twice a week, for a total of 24 weeks of treatment. A significant time × group interaction was evident, suggesting that patients undergoing CACR intervention improved in specific metacognitive sub-functions (understanding others' mind and mastery), some cognitive domains (verbal learning processing speed, visual learning, reasoning, and problem solving) (h2 = 0.126), depressive symptoms, SC, awareness of symptoms, and real-world functioning domains (community activities and interpersonal relationships) more significantly than did patients undergoing CAG. The most noticeable differential improvement between the two groups was detected in two metacognitive sub-functions (understanding others' mind and mastery), in verbal learning, in interpersonal relationship, and in depressive symptomatology, achieving large effect sizes. These are encouraging findings in support of the possible integration of CACR in rehabilitation practice in the Italian mental health services.

RESUMO

PURPOSE: To analyse the healthcare resource consumption and related costs for the Italian National Health System of patients estimated to be affected by treatment-resistant depression (TRD) in Italy. PATIENTS AND METHODS: This was an observational retrospective study based on administrative databases, including those related to residential/semiresidential structures, of Veneto Region and the Local Health Unit of Bergamo in Italy (for a total of around 6 million health-assisted subjects). Between July 2011 and December 2017, all adult patients with a third antidepressant (AD) after ≥2 AD (each one with at least ≥4 weeks duration, ≥1 prescription at maximum dosage reported in datasheets, a grace period ≤30 days when switching AD and treatment maintained ≥9 months) were included. Overall and psychiatry-related healthcare resources consumption and related costs were estimated on a 12-months based analysis. Data were re-proportioned to the Italian population. RESULTS: We have previously estimated a total of 101,455 patients with TRD in Italy (130,049 considering the mean maximum dosage of AD). Of them, 44.2% had at least a psychiatric hospitalization/visit or accessed a residential/semiresidential structure, and 31% added another AD or a mood stabilizer/antipsychotic drug. Patients with at least one psychiatry-related hospitalization increased over the number of antidepressant lines from 12.0% during first line up to 24.5% during fourth line. Direct healthcare costs increased from €4,405 for first line to €9,251 from fifth line onwards. Psychiatry-related costs went from €1,817 (first line) to €4,606 (fifth line onwards) and were mainly driven by residential/semiresidential structures and hospitalizations. CONCLUSION: An upward trend with number of AD lines was observed for all healthcare resource utilization and consequently for all direct costs, thus indicating an increasing burden for patients as they move forward AD lines.

RESUMO

This survey explores how psychiatrists, service users and family members in Italy perceive the term schizophrenia and if they consider a name change a useful option in order to overcome the stigma attached to it. Opinions on the term schizophrenia were collected by a self-rated questionnaire used in previous international surveys. Questionnaires were delivered members of the Italian Psychiatric Association. Survey of mental health users was conducted among members of the main users' association of the Veneto region; survey of family members was conducted among one of the most representative Italian family association. Overall, 350 psychiatrists, 71 mental health users and 110 family members filled in the questionnaires. Considering the whole sample, 41.5% found the term inappropriate, 67.6% stigmatizing and 72.3% advocated a name change. Among psychiatrists 57% reported that schizophrenia was inappropriate, 70% considered the term stigmatizing and 71% was in favor of a name change. Similarly, 56% of service users and 71% of family members found schizophrenia a stigmatizing term and, respectively, 75% and 77% advocated a name change. Conflicting results were found on possible alterative terms: psychiatrists proposed a wide range of possible options, most of which referred to the term 'psychosis' (53%), whereas users and family members preferred terms referring to the broad category of 'mental health suffering'. Overall, most of respondents in the three stakeholders' groups agree that schizophrenia should be renamed to reduce the stigma attached to it; the main challenge, however, is the lack of consensus on the best alternative term to use.

RESUMO

BACKGROUND: To date, very few nationwide studies addressing the way in which mental health services are addressing the current pandemics have been published. The present paper reports data obtained from a survey relating to the Italian mental health system conducted during the first phase of the Covid-19 epidemic. METHODS: Two online questionnaires regarding Community Mental Health Centres (CMHC) and General Hospital Psychiatric Wards (GHPW), respectively, were sent to the Heads of all Italian Mental Health Departments (MHDs). Statistical analysis was carried out by means of Chi Square test with Yates correction or the Fisher Exact test, as needed. RESULTS: Seventy-one (52.9%) of the 134 MHDs and 107 (32.6%) of the 318 GHPWs returned completed questionnaires. Less than 20% of CMHCs were closed and approx. 25% had introduced restricted access hours. A substantial change in the standard mode of operation in CMHCs was reported with only urgent psychiatric interventions, compulsory treatments and consultations for imprisoned people continuing unchanged. All other activities had been reduced to some extent. Remote contacts with users had been set up in about 75% of cases. Cases of COVID positivity were reported for both staff members (approx. 50% of CHMCs) and service users (52% of CHMCs). 20% of CMHCs reported cases of increased aggressiveness or violence among community patients, although only 8.6% relating to severe cases. Significant problems emerged with regard to the availability of personal protective equipment (PPE) for staff members. A reduced number of GHPWs (- 12%), beds (approx.-30%) and admissions were registered (87% of GHPWs). An increase in compulsory admissions and the rate of violence towards self or others among inpatients was reported by 8% of GHPWs. Patient swabs were carried out in 50% of GHPWs. 60% of GHPWs registered the admission to general COVID-19 Units of symptomatic COVID+ non-severe psychiatric patients whilst COVID+ severe psychiatric patients who were non-collaborative were admitted to specifically set up "COVID-19" GHPWs or to isolated areas of the wards purposely adapted for the scope. CONCLUSIONS: The pandemic has led to a drastic reduction in levels of care, which may produce a severe impact on the mental health of the population in relation to the consequences of the expected economic crisis and of the second ongoing wave of the pandemic.

RESUMO

Treatment guidelines (GL) in psychiatry represent a useful and functional tool to be explored and enhanced in terms of the contribution of patient care and the promotion of scientific improvement. However, they show some limitations, both clinical and forensic. The objective of this paper is to examine the objectives, the clinical limitations and the applicability of the GL on professional liability (forensic aspects). From a clinical point of view, the GL have objectives that are functional to the promotion of physical and mental health, among which the constitutional observance of the right to health, the improvement of public health, the implementation of best clinical practices, the promotion of scientific research, the professional training of operators in the field of physical and mental health. However, GL cannot replace a contextualized clinical judgment. GL must be applied, in the single clinical case, in light of their multiple criticalities, including the limits of the methodology used for their formulation, the differences between the GL' recommendations, the difficulty of their application in daily clinical practice, the lack of specific treatment interventions. From a forensic psychiatric point of view, GL, as currently conceived, cannot be used in terms of professional liability without their interpretation on a legal basis with forensic psychiatric methodology, similarly to any other clinical and scientific information, with its qualifications and criticalities.

RESUMO

BACKGROUND: Internet-based Cognitive Behavioural Therapy (iCBT) is found effective in treating common mental disorders. However, the use of these interventions in routine care is limited. The international ImpleMentAll study is funded by the European Union's Horizon 2020 programme. It is concerned with studying and improving methods for implementing evidence-based iCBT services for common mental disorders in routine mental health care. A digitally accessible implementation toolkit (ItFits-toolkit) will be introduced to mental health care organizations with the aim to facilitate the ongoing implementation of iCBT services within local contexts. This study investigates the effectiveness of the ItFits-toolkit by comparing it to implementation-as-usual activities. METHODS: A stepped wedge cluster randomized controlled trial (SWT) design will be applied. Over a trial period of 30 months, the ItFits-toolkit will be introduced sequentially in twelve routine mental health care organizations in primary and specialist care across nine countries in Europe and Australia. Repeated measures are applied to assess change over time in the outcome variables. The effectiveness of the ItFits-toolkit will be assessed in terms of the degree of normalization of the use of the iCBT services. Several exploratory outcomes including uptake of the iCBT services will be measured to feed the interpretation of the primary outcome. Data will be collected via a centralized data collection system and analysed using generalized linear mixed modelling. A qualitative process evaluation of routine implementation activities and the use of the ItFits-toolkit will be conducted within this study. DISCUSSION: The ImpleMentAll study is a large-scale international research project designed to study the effectiveness of tailored implementation. Using a SWT design that allows to examine change over time, this study will investigate the effect of tailored implementation on the normalization of the use of iCBT services and their uptake. It will provide a better understanding of the process and methods of tailoring implementation strategies. If found effective, the ItFits-toolkit will be made accessible for mental health care service providers, to help them overcome their context-specific implementation challenges.

RESUMO

BACKGROUND: The System Usability Scale (SUS) is used to measure usability of internet-based Cognitive Behavioural Therapy (iCBT). However, whether the SUS is a valid instrument to measure usability in this context is unclear. The aim of this study is to assess the factor structure of the SUS, measuring usability of iCBT for depression in a sample of professionals. In addition, the psychometric properties (reliability, convergent validity) of the SUS were tested. METHODS: A sample of 242 professionals using iCBT for depression from 6 European countries completed the SUS. Confirmatory Factor Analysis (CFA) was conducted to test whether a one-factor, two-factor, tone-model or bi-direct model would fit the data best. Reliability was assessed using complementary statistical indices (e.g. omega). To assess convergent validity, the SUS total score was correlated with an adapted Client Satisfaction Questionnaire (CSQ-3). RESULTS: CFA supported the one-factor, two-factor and tone-model, but the bi-factor model fitted the data best (Comparative Fit Index = 0.992, Tucker Lewis Index = 0.985, Root Mean Square Error of Approximation = 0.055, Standardized Root Mean Square Residual = 0.042 (respectively χ2diff (9) = 69.82, p < 0.001; χ2diff (8) = 33.04, p < 0.001). Reliability of the SUS was good (ω = 0.91). The total SUS score correlated moderately with the CSQ-3 (CSQ1 rs = .49, p < 0.001; CSQ2 rs = .46, p < 0.001; CSQ3 rs = .38, p < 0.001), indicating convergent validity. CONCLUSIONS: Although the SUS seems to have a multidimensional structure, the best model showed that the total sumscore of the SUS appears to be a valid and interpretable measure to assess the usability of internet-based interventions when used by professionals in mental healthcare.

RESUMO

BACKGROUND AND OBJECTIVE: Clinical practice guidelines recommend antipsychotic monotherapy, including oral and long-acting formulations, in the treatment of schizophrenia. This open-label, randomized, controlled trial aimed to evaluate the efficacy and tolerability in patients with schizophrenia of once-monthly long-acting paliperidone palmitate (PP1M) compared with oral paliperidone extended release (ER), with a particular focus on satisfaction, subjective well-being, and service engagement. METHODS: Seventy-two consecutive outpatients with schizophrenia (DSM-5) were randomly assigned for 6 months to: (1) PP1M (50-150 mg equivalent) or (2) paliperidone ER (6-12 mg/day). Participants were assessed at baseline and after 6 months with the Treatment Satisfaction Questionnaire for Medication (TSQM); the Subjective Well-being under Neuroleptics Scale (SWN-K); the Service Engagement Scale (SES); the Clinical Global Impression-Schizophrenia (CGI-SCH); and the Personal and Social Performance (PSP) score. ANOVA repeated measures was performed. Intention-to-treat analysis with last observation carried forward was conducted. RESULTS: We found a significant within-subjects effect (trial duration) for all rating scale except for cognitive symptoms and the TSQM domain "side effects". A significant effect between subjects (treatment modality) was found for the CGI negative symptoms, the TSQM domains "overall satisfaction" and "convenience," and the SES. There were seven drop-outs (9.7%): twi due to hyperprolactinemia and five for lack of compliance. CONCLUSIONS: Significant differences between the two formulations were found. PP1M was superior to paliperidone ER on global treatment satisfaction and convenience, on service engagement, and in reducing negative symptoms. The trial was registered in the Australian New Zealand Clinical Trials Registry (ANZCTR) with the code: ACTRN12618001113246.

RESUMO

We administered structured interviews to managers and staff of a random sample of 265 Italian psychiatric Residential Facilities (RFs). Most are independent buildings, located in urban and suburban areas. The median number of residents is 10. The few RFs (5.7%) with more than 20 beds have a higher rate of drop-outs and escapes. The average indoor space per resident is 36 square meters, there is often a garden, and residents generally live in two-bed rooms. Most facilities are located within walking distance of shopping centers or recreational facilities. Three-quarters have 24-hour staff coverage. On average, each facility has about 10 full-time equivalent workers, with a staff:resident ratio of 0.92. Most of the professional input is provided by nurses and auxiliary staff. Critical issues to be considered in planning facilities include the physical environment, the size, and the staffing patterns.

RESUMO

BACKGROUND: Although residential facilities (RFs) have largely replaced mental hospitals (MHs) in most developed countries for the long-term residential care of severely impaired patients, the process of care in RFs has not been well studied. The aim of this paper is to investigate the process of care in 265 RFs, representing 19.3% of all RFs in Italy, and to devise a classification of RFs based on process characteristics. METHODS: Structured interviews were conducted with the manager and staff of each RF. Residents were evaluated using standardized rating instruments. RESULTS: Most RFs had specific admission criteria, with one third having a waiting list that averaged about 3 months. There was no formal limitation to the length of stay in three quarters of RFs, and turnover rates were very low. Although a homelike atmosphere was found in many RFs, most facilities had restrictive rules on patients' daily lives and behaviours. RFs carried out several external activities targeted at integrating patients within the local community. Standardized assessment instruments and written treatment plans were rarely used. A cluster analysis based on the levels of restrictiveness and the standardization of the process of care classified RFs into five groups that differed with respect to daily staff coverage, size, geographical distribution and proportion of former MH residents. No significant intercluster differences were associated with the current clinical and psychosocial characteristics of residents, or with several other outcome variables. CONCLUSIONS: This study provides naturalistic evidence of the heterogeneity of the process of residential care on a large scale. Future efforts should focus on developing an empirical classification of RFs, as well as on national and international standards of care and staffing to address patients' needs.

RESUMO

This study has two goals. The first goal is to assess the prevalence of psychiatric disorders in orthotopic liver transplantation (OLT) candidates by means of standardized procedures because there has been little research concerning psychiatric problems of potential OLT candidates using standardized instruments. The second goal focuses on identifying predictors of these psychiatric disorders. One hundred sixty-five elective OLT candidates were assessed by our unit. Psychiatric diagnoses were based on the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Patients also were assessed using the Hamilton Depression Rating Scale (HDRS) and the Spielberger Anxiety Index, State and Trait forms (STAI-X1 and STAI-X2). Severity of cirrhosis was assessed by applying Child-Pugh score criteria. Chi-squared and general linear model analysis of variance were used to test the univariate association between patient characteristics and both clinical psychiatric diagnoses and severity of psychiatric diseases. Variables with P less than.10 in univariate analyses were included in multiple regression models. Forty-three percent of patients presented at least one psychiatric diagnosis. Child-Pugh score and previous psychiatric diagnoses were independent significant predictors of depressive disorders. Severity of psychiatric symptoms measured by psychometric scales (HDRS, STAI-X1, and STAI-X2) was associated with Child-Pugh score in the multiple regression model. Our data suggest a high rate of psychiatric disorders, particularly adjustment disorders, in our sample of OLT candidates. Severity of liver disease emerges as the most important variable in predicting severity of psychiatric disorders in these patients.

RESUMO

OBJECTIVES: The evaluation of the possible role of dopamine in psychiatric disorders has been limited by the relative inadequacy of tools. A tempting approach to examine alterations of dopaminergic system in major depression is to examine the expression of dopamine receptors in peripheral blood mononuclear cells (PBMC). METHODS: D4 dopamine receptor (D4DR) messenger RNA (mRNA) expression in PBMC from 12 patients with major depressive disorder was examined before and after an 8-week treatment with paroxetine at 20-50 mg/day. Ten healthy subjects were analyzed in parallel. The relative content of D4DR mRNA was determined by reverse transcriptase-polymerase chain reaction (RT-PCR). using beta-actin as internal standard. RESULTS: D4DR mRNA levels were significantly decreased in untreated depressed patients as compared to controls. D4DR mRNA expression returned to control levels after paroxetine treatment, when patients achieved a significant improvement of depressive symptoms. CONCLUSIONS: Results of our study suggest the role of PBMC D4DR mRNA expression as a peripheral marker of the central dopaminergic function in major depression.

RESUMO

BACKGROUND: The purpose of this study was to provide preliminary data on the effects of paroxetine and amisulpride on depressive dimensions, analyzed by factor analysis, in dysthymic patients. METHODS: One hundred and eighteen patients with DSM IV criteria for DD without concurrent major depression were enrolled in this 8-week, open study, and 100 completed it. Symptom dimensions were identified by principal components analysis with the SAS Factor procedure. RESULTS: Results of the symptom rating scales indicated that both drugs were equally effective. Response rate was 65% both in the paroxetine and the amisulpride group and the proportions of patients achieving a final HRSD score < or =7 were 46.7 and 55%, respectively. MADRS factor analysis identified two factors at baseline: the first corresponding to the global severity of depression and the second to somatic symptoms. After 8 weeks of treatment only one factor could be substantiated. At week 4 both paroxetine and amisulpride produced significant improvements on factor 1 while at week 8 mean changes of factor 1 were greater in the amisulpride-treated patients. LIMITATIONS: The main limitation was the open-label design. CONCLUSIONS: Both paroxetine and amisulpride appear to be effective in the short-term management of DD, improving its most characteristic symptoms.
