RESUMEN

BACKGROUND: Joint crisis plans (JCPs) are offered in many psychiatric hospitals, but patients only rarely make use of them. OBJECTIVE: To assess the rates of JCPs among inpatients of mental health hospitals and to analyze the clinical characteristics of patients who make use of a JCP. MATERIAL AND METHODS: We carried out a retrospective analysis of routine data from the statistical database/basis documentation of the LVR hospital association, which consists of nine psychiatric hospitals. The basis documentation is consistent in the nine hospitals. All admissions between 2016 and 2020 were considered. We recorded the existence of a JCP, age, gender and main diagnosis at release, as well as previous hospital stays, detention under the Mental Health Act of the Federal State of NRW and experiences with compulsory measures (seclusion/restraint) in the previous 24 months before index admission. RESULTS: Out of a total of 117,662 inpatients 467 (0.4%) had completed a JCP. Patients with JCP were more likely to be diagnosed with schizophrenia, bipolar disorder, or emotionally unstable personality disorder. Patients with a JCP had more previous inpatient stays and they had more frequently experienced detentions and compulsory measures. However, 50% of the patients with a JCP had other diagnoses and the vast majority of them had experienced no detention or compulsory measure in the 24 months preceding the first documentation of a JCP. CONCLUSIONS: Overall, the use of JCPs is limited. The targeted group of patients with severe mental illness and previous experience with involuntary placements and compulsory measures make use of the offer of a JCP but so do other patients as well. Additional qualitative analyses are required in order to analyze the content and objectives of JCPs in more detail.

RESUMEN

Quality indicators are vital for monitoring the transformation of institution-based mental health services towards the provision of person-centered mental healthcare. While several mental healthcare quality indicators have been identified as relevant and valid, their actual usability and utility for routine monitoring healthcare quality over time is significantly determined by the availability and trustworthiness of the underlying data. In this feasibility study, quality indicators that have been systematically identified for use in the Danube region countries of Bulgaria, the Czech Republic, Hungary, and Serbia were measured on the basis of existing mental healthcare data in the four countries. Data were collected retrospectively by means of the best available, most standardized, trustworthy, and up-to-date data in each country. Out of 21 proposed quality indicators, 18 could be measured in Hungary, 17 could be measured in Bulgaria and in the Czech Republic, and 8 could be measured in Serbia. The results demonstrate that a majority of quality indicators can be measured in most of the countries by means of already existing data, thereby demonstrating the feasibility of quality measurement and regular quality monitoring. However, data availability and usability are scattered across countries and care sectors, which leads to variations in the quality of the quality indicators themselves. Making the planning and outputs of national mental healthcare reforms more transparent and evidence-based requires (trans-)national standardization of healthcare quality data, their routine availability and standardized assessment, and the regular reporting of quality indicators.

RESUMEN

E-mental health (eMH) encompasses the use of digital technologies to deliver, support, or enhance mental health services. Despite the growing evidence for the effectiveness of eMH interventions, the process of implementation of eMH solutions in healthcare remains slow throughout Europe. To address this issue, the e-Mental Health Innovation and Transnational Implementation Platform North-West Europe (eMEN) project was initiated to increase the dissemination and quality of eMH services in Europe. In this project, status analyses regarding eMH in the six participating countries (i.e., Belgium, France, Germany, Ireland, The Netherlands, and the UK) were conducted and eight recommendations for eMH were developed. Expert teams from the six participating countries conducted status analyses regarding the uptake of eMH based on a narrative literature review and stakeholder interviews. Based on these status analyses, the eMEN consortium developed eight policy recommendations to further support the implementation of eMH in Europe. The status analyses showed that the participating countries are in different stages of implementing eMH into mental healthcare. Some barriers to implementing eMH were common among countries (e.g., a limited legal and regulatory framework), while others were country-specific (e.g., fragmented, federal policies). The policy recommendations included fostering awareness, creating strong political commitment, and setting reliable standards related to ethics and data security. The eMEN project has provided the initial recommendations to guide political and regulatory processes regarding eMH. Further research is needed to establish well-tailored implementation strategies and to assess the generalizability of the recommendations beyond the countries involved in the eMEN project.

RESUMEN

BACKGROUND: The purpose of this study was to identify factors associated with a high risk of involuntary psychiatric in-patient hospitalization both on the individual level and on the level of mental health services and the socioeconomic environment that patients live in. METHODS: The present study expands on a previous analysis of the health records of 5764 cases admitted as in-patients in the four psychiatric hospitals of the Metropolitan City of Cologne, Germany, in the year 2011 (1773 cases treated under the Mental Health Act and 3991 cases treated voluntarily). Our previous analysis had included medical, sociodemographic and socioeconomic data of every case and used a machine learning-based prediction model employing chi-squared automatic interaction detection (CHAID). Our current analysis attempts to improve the previous one through (1) optimizing the machine learning procedures (use of a different type of decision-tree prediction model (Classification and Regression Trees (CART) and application of hyperparameter tuning (HT)), and (2) the addition of patients' environmental socioeconomic data (ESED) to the data set. RESULTS: Compared to our previous analysis, model fit was improved. Main diagnoses of an organic mental or a psychotic disorder (ICD-10 groups F0 and F2), suicidal behavior upon admission, admission outside of regular service hours and absence of outpatient treatment prior to admission were confirmed as powerful predictors of detention. Particularly high risks were shown for (1) patients with an organic mental disorder, specifically if they were retired, admitted outside of regular service hours and lived in assisted housing, (2) patients with suicidal tendencies upon admission who did not suffer from an affective disorder, specifically if it was unclear whether there had been previous suicide attempts, or if the affected person lived in areas with high unemployment rates, and (3) patients with psychosis, specifically those who lived in densely built areas with a large proportion of small or one-person households. CONCLUSIONS: Certain psychiatric diagnoses and suicidal tendencies are major risk factors for involuntary psychiatric hospitalization. In addition, service-related and environmental socioeconomic factors contribute to the risk for detention. Identifying modifiable risk factors and particularly vulnerable risk groups should help to develop suitable preventive measures.

RESUMEN

BACKGROUND: In spite of a well-developed and complex mental healthcare system in Germany, problems remain in the capacity of psychotherapeutic care with an undersupply and long waiting times for provision of outpatient psychotherapeutic care. OBJECTIVES: The analyses address the current level of psychotherapeutic care and the role of individual medical specialties in outpatient psychotherapeutic care in Germany. MATERIAL AND METHODS: The analyses are based on secondary data from three statutory health insurance companies and the German pension funds for the years 2005-2007. Anonymized treatment data from 3.3 million insured persons with a diagnosis of a mental disorder (ICD-10 groups F0-F5) were analyzed. RESULTS: In outpatient treatment 9,670,588 psychotherapeutic accounting codes were analyzed of which 33 % were psychiatric, psychosomatic or psychotherapeutic consultations that are not covered by the scope of psychotherapy according to the standard regulations (psychotherapy guidelines). The most frequently used psychotherapeutic services were verbal interventions (accounting codes 35.100 and 31.110) and psychiatric consultations (accounting codes 14.220, 21.220 and 21.221), independent of the mental disorder. Of the patients 5.9 % received directive psychotherapy. The provider-specific analysis showed a great variation in the kind of accounting codes, which were brought into account by the different providers. CONCLUSION: With regard to the reform efforts in psychotherapeutic care, longitudinal trends in the utilization and quality of psychotherapeutic care in the individual fields of treatment should be analyzed in follow-up studies.

RESUMEN

BACKGROUND: Prior to nationwide implementation, the feasibility of newly developed quality indicators must be assessed. The aim of this multicenter feasibility test was an evaluation of the measurability of cross-sectoral quality indicators for depression and schizophrenia by means of routine data. METHODS: The feasibility of the quality indicators was assessed in ten specialist clinics for psychiatry and psychotherapy by means of retrospective analyses of anonymous routine data. The data were extracted from the routine clinical documentation of the hospital information systems and the data from the admission and discharge sheets of the basic documentation in psychiatry (BADO) were additionally used for some clinics. Analyses were conducted for all cases of adults diagnosed with depression or schizophrenia within predefined assessment periods. RESULTS: In total five indicators for depression and nine indicators for schizophrenia were assessed and evaluated as measurable or measurable to a limited extent, sometimes with slight adaptations in the operationalization of the indicator. Due to variations in documentation, some indicators could not be calculated for all clinics. Most indicators could be collated with the data from the BADO. CONCLUSION: An assessment of indicators that measure quality-relevant aspects of care in depression and schizophrenia, is partially feasible by means of current routine data documentation analysis from the participating clinics. However, differing documentation methodologies in the participating clinics impeded a uniform assessment; therefore, for the implementation of nationwide minimum standards for the quality assurance of mental healthcare, a uniform cross-sectoral documentation methodology should be adapted to consensus and relevant quality indicators. The BADO appears to be a suitable instrument for this purpose.

RESUMEN

BACKGROUND AND OBJECTIVES: The German health interview and examination survey for adults (DEGS1) with the mental health module (DEGS1-MH) is the successor to the last survey of mental disorders in the general German population 15 years ago (GHS-MHS). This paper reports the basic findings on the 12-month prevalence of mental disorders, associated disabilities and self-reported healthcare utilization. METHODS: A representative national cohort (age range 18-79 years, n = 5,317) was selected and individuals were personally examined (87.5 % face to face and 12.5 % via telephone) by a comprehensive clinical interview using the composite international diagnostic interview (CIDI) questionnaire. RESULTS: The overall 12-month prevalence of mental disorders was 27.7 % with substantial differences between subgroups (e.g. sex, age, socioeconomic status). Mental disorders were found to be particularly impairing (elevated number of disability days). Less than 50 % of those affected reported to be in contact with health services due to mental health problems within the last 12 months (range 10-40 % depending on the number of diagnoses). CONCLUSIONS: Mental disorders were found to be commonplace with a prevalence level comparable to that found in the 1998 predecessor study but several further adjustments will have to be made for a sound methodological comparison between the studies. Apart from individual distress, elevated self-reported disability indicated a high societal disease burden of mental disorders (also in comparison with many somatic diseases). Despite a relatively comprehensive and well developed mental healthcare system in Germany there are still optimisation needs for treatment rates.

RESUMEN

Mutations in the human gene for the myelin recognition molecule protein zero (P0) give rise to severe and progressive forms of dominantly inherited peripheral neuropathies. We have previously reported that mice homozygous for a null mutation in P0 have severely hypomyelinated nerves ten weeks after birth. Here we show hypomyelination already exists at day four with subsequent demyelination and impaired nerve conduction. Furthermore, heterozygous mutants show normal myelination, but develop progressive demyelination after four months of age. Thus, the pathology of homo- and heterozygous P0 mutants resembles that of the severely affected Déjérine-Sottas and the more mildly affected Charcot-Marie-Tooth type 1B patients, respectively.

RESUMEN

Peripheral myelin protein PMP22 has been suggested to have a role in peripheral nerve myelination and cell proliferation. Defects at the PMP22 locus are associated with peripheral neuropathies such as Charcot-Marie-Tooth disease type 1A. We now demonstrate that mice devoid of Pmp22 are retarded in the onset of myelination and develop abundant sausage-like hypermyelination structures (tomacula) at a young age followed by severe demyelination, axonal loss and functional impairment. Mice carrying one functional copy of Pmp22 are less affected but they also exhibit focal tomacula comparable to the morphological features in hereditary neuropathy with liability to pressure palsies (HNPP). We conclude that Pmp22 is required for the correct development of peripheral nerves, the maintenance of axons and the determination of myelin thickness and stability.

RESUMEN

Treatment guidelines provide evidence-based recommendations for diagnosis and treatment to assist clinicians, care givers and patients in finding an optimized treatment option in given clinical situations. Specific treatment guidelines for schizophrenia issued by the German Association of Psychiatry, Psychotherapy and Psychosomatics (DGPPN) and published under the auspices of the Working Group for Scientific Medical Specialist Societies (AWMF) (i.e. fulfilling the highest quality standards at the S3 level) have been available in Germany since 2006. Currently, a comprehensive revision process is ongoing to update these guidelines with the aim to publish the revision before 2014. However, since publication of the German treatment guidelines many clinical trials and meta-analyses have been published which appear to make a new evaluation of antipsychotic drug treatment necessary. Currently available national and international guidelines, such as the WFSBP, PORT and NICE guidelines, place less emphasis on the general superiority of atypical antipsychotic medication but support the idea to evaluate antipsychotic drugs based on the side effect profiles. The present overview discusses the recent guidelines development processes regarding schizophrenia and compares the available German treatment guidelines with recently published international guidelines. Current developments and issues for discussion are described in detail to provide possible implications for changes in treatment recommendations.

RESUMEN

BACKGROUND: Valid and feasible quality indicators can measure healthcare quality and show potential for improvement in care. The German Association for Psychiatry and Psychotherapy (DGPPN) has developed trans-sectoral quality indicator sets for four mental disorders with high prevalence (alcohol dependence, dementia, depression and schizophrenia). MATERIAL AND METHOD: The DGPPN followed a structured multistage process and used guideline recommendations and the results of systematic evidence searches as the basis for the development of these quality indicators. This was followed by a structured consensus process for all quality indicators. RESULTS: Four evidence and consensus-based, diagnosis-specific and trans-sectoral quality indicator sets have been developed. CONCLUSION: It is possible to develop quality indicators on the basis of guideline recommendations. The implementation of the DGPPN quality indicators will play a crucial role in order to evaluate their utility and feasibility as quality measures for German mental healthcare.

RESUMEN

In August 2002 the Japanese Society of Psychiatry and Neurology decided to rename the Japanese expression for schizophrenia from Sêshin Bunretsu Byô to Tôgô Shicchô Shô. Currently the psychiatric classification systems ICD-10 and DSM-IV are under revision. Against this background the Japanese process of renaming a psychiatric disorder is of high interest as far as the clinical, social and cultural implications of the new name are concerned.The authors give an overview of the Japanese process of renaming schizophrenia. Its background and realization are explained and the expectations of Japanese physicians, patients and their families related to the new name are analysed. Furthermore, its effects are evaluated. The aim of the paper is to clarify in how far the Japanese example may serve as a model for evaluating the possible implications that a renaming or nosological redefinition of schizophrenia might have in the course of the revision process of ICD 10 and DSM IV.

RESUMEN

BACKGROUND: The quality of mental health services is crucial for the effectiveness and efficiency of mental healthcare systems, symptom reduction, and quality of life improvements in persons with mental illness. In recent years, particularly care coordination (i.e., the integration of care across different providers and treatment settings) has received increased attention and has been put into practice. Thus, we focused on care coordination in this update of a previous European Psychiatric Association (EPA) guidance on the quality of mental health services. METHODS: We conducted a systematic meta-review of systematic reviews, meta-analyses, and evidence-based clinical guidelines focusing on care coordination for persons with mental illness in three literature databases. RESULTS: We identified 23 relevant documents covering the following topics: case management, integrated care, home treatment, crisis intervention services, transition from inpatient to outpatient care and vice versa, integrating general and mental healthcare, technology in care coordination and self-management, quality indicators, and economic evaluation. Based on the available evidence, we developed 15 recommendations for care coordination in European mental healthcare. CONCLUSIONS: Although evidence is limited, some concepts of care coordination seem to improve the effectiveness and efficiency of mental health services and outcomes on patient level. Further evidence is needed to better understand the advantages and disadvantages of different care coordination models.

RESUMEN

Acute porphyrias are inherited disorders caused by partial deficiency of specific heme biosynthesis enzymes. Clinically, porphyrias are manifested by a neuropsychiatric syndrome that includes peripheral neuropathy. Although much is known about the porphyrias' enzyme defects and their biochemical consequences, the cause of the neurological manifestations remains unresolved. We have studied porphyric neuropathy in mice with a partial deficiency of porphobilinogen deaminase (PBGD). PBGD-deficient mice (PBGD-/-) imitate acute porphyria through massive induction of hepatic delta-aminolevulinic acid synthase by drugs such as phenobarbital. Here we show that PBGD-/- mice develop impairment of motor coordination and muscle weakness. Histologically femoral nerves of PBGD-/- mice exhibit a marked decrease in large-caliber (>8 microm) axons and ultrastructural changes consistent with primary motor axon degeneration, secondary Schwann cell reactions, and axonal regeneration. These findings resemble those found in studies of affected nerves of patients with acute porphyria and thus provide strong evidence that PBGD deficiency causes degeneration of motor axons without signs of primary demyelination, thereby resolving a long-standing controversy. Interestingly, the neuropathy in PBGD-/- mice developed chronically and progressively and in the presence of normal or only slightly (twofold) increased plasma and urinary levels of the putative neurotoxic heme precursor delta-aminolevulinic acid. These data suggest that heme deficiency and consequent dysfunction of hemeproteins can cause porphyric neuropathy.

RESUMEN

The aim of this EPA guidance was to develop recommendations on eMental health interventions in the treatment of posttraumatic stress disorder (PTSD). A systematic literature search was performed and 40 articles were retrieved and assessed with regard to study characteristics, applied technologies, therapeutic approaches, diagnostic ascertainment, efficacy, sustainability of clinical effects, practicability and acceptance, attrition rates, safety, clinician-supported vs. non-supported interventions and active vs. waiting-list controls. The reviewed studies showed a great heterogeneity concerning study type, study samples, interventions and outcome measures. Based on these findings, five graded recommendations dealing with symptom reduction, acceptability, type of administration, clinician support, self-efficacy and coping were developed.

RESUMEN

The adhesive cell surface molecule P(0) is the most abundant glycoprotein in peripheral nerve myelin and fulfills pivotal functions during myelin formation and maintenance. Mutations in the corresponding gene cause hereditary demyelinating neuropathies. In mice heterozygously deficient in P(0) (P(0)(+/-) mice), an established animal model for a subtype of hereditary neuropathies, T-lymphocytes are present in the demyelinating nerves. To monitor the possible involvement of the immune system in myelin pathology, we cross-bred P(0)(+/-) mice with null mutants for the recombination activating gene 1 (RAG-1) or with mice deficient in the T-cell receptor alpha-subunit. We found that in P(0)(+/-) mice myelin degeneration and impairment of nerve conduction properties is less severe when the immune system is deficient. Moreover, isolated T-lymphocytes from P(0)(+/-) mice show enhanced reactivity to myelin components of the peripheral nerve, such as P(0), P(2), and myelin basic protein. We hypothesize that autoreactive immune cells can significantly foster the demyelinating phenotype of mice with a primarily genetically based peripheral neuropathy.

RESUMEN

OBJECTIVE: To investigate the effect of an antiedematous therapy with the histamine antagonist ketotifen on beta-cell function in late prediabetes. RESEARCH DESIGN AND METHODS: In a randomized double-blind placebo-controlled study, ketotifen was administered for 3 months to 9 islet cell antibody positive (ICA+) prediabetic patients with a first-phase insulin response (FPIR) below the 2.5th percentile to preserve residual beta-cell function. Patients were followed by intravenous glucose tolerance tests (IVGTTs) every 4-6 weeks for determination of FPIR, HbA1, ICAs, and insulin autoantibodies. In 5 patients, the immune activation state was followed by determination of serum levels of tumor necrosis factor-alpha (TNF-alpha), beta 2-microglobulin, and C-reactive protein (CRP). RESULTS: Seven of nine patients developed diabetes within one year of follow-up. Irrespective of treatment with ketotifen, a slow and linear decline (P < 0.05) of 1 + 3-min insulin values was observed in sequential IVGTTs in those 7 patients who developed insulin-dependent diabetes mellitus (IDDM) during follow-up. The 2 other patients showed wide fluctuations of the insulin response with a threefold increase of initial insulin levels. HbA1 did not correlate with FPIR. Fasting blood glucose increased significantly during the study (P < 0.05). Individual levels of serum TNF-alpha, CRP, and beta 2-microglobulin did not change during the study. CONCLUSIONS: The study could not demonstrate preservation of beta-cell function by ketotifen in the late stage before manifestation of clinical diabetes.
