Evolution of psychosocial burden and psychiatric symptoms in patients with psychiatric disorders during the Covid-19 pandemic.

The Covid-19 pandemic highly impacts mental health worldwide. Patients with psychiatric disorders are a vulnerable risk population for worsening of their condition and relapse of symptoms. This study investigates the pandemic-related course of psychosocial burden in patients with pre-existing mental disorders. With the newly developed Goettingen psychosocial Burden and Symptom Inventory (Goe-BSI) psychosocial burden has been traced retrospectively (1) before the pandemic (beginning of 2020), (2) at its beginning under maximum lockdown conditions (March 2020), and (3) for the current state after maximum lockdown conditions (April/May 2020). The Goe-BSI also integrates the Adjustment Disorder New Module (ADNM-20), assesses general psychiatric symptoms, and resilience. A total of 213 patients covering all major psychiatric disorders (ICD-10 F0-F9) were interviewed once in the time range from April, 24th until May 11th, 2020. Across all diagnoses patients exhibited a distinct pattern with an initial rise followed by a decline of psychosocial burden (p < 0.001, partial η2 = 0.09; Bonferroni-corrected pairwise comparisons between all three time-points: p < 0.05 to 0.001). Female gender and high ADNM-20 scores were identified as risk factors for higher levels and an unfavorable course of psychosocial burden over time. Most psychiatric symptoms remained unchanged. Trajectories of psychosocial burden vary in parallel to local lockdown restrictions and seem to reflect an adaptive stress response. For female patients with pre-existing mental disorders and patients with high-stress responses, timely and specific treatment should be scheduled. With the continuation of the pandemic, monitoring of long-term effects is of major importance, especially when long incubation times for the development of mental health issues are considered.

Medium-term and peri-lockdown course of psychosocial burden during the ongoing COVID-19 pandemic: a longitudinal study on patients with pre-existing mental disorders.

While the COVID-19 pandemic continues, patients with pre-existing mental disorders are increasingly recognized as a risk group for adverse outcomes. However, data are conflicting and cover only short time spans so far. Here, we investigate the medium-term and peri-lockdown-related changes of mental health outcomes in such patients in a longitudinal study. A cohort of 159 patients comprising all major mental disorders (ICD-10 F0-F9) were interviewed twice with the Goettingen psychosocial Burden and Symptom Inventory (Goe-BSI) to evaluate psychosocial burden, psychiatric symptoms and resilience at the end of the first (April/May 2020) and the second lockdown in Germany (November/December 2020). For the primary outcome "psychosocial burden" ratings also comprised retrospective pre-pandemic (early 2020) and very early states during the pandemic (March 2020). For all diagnostic groups, psychosocial burden varied significantly over time (p < 0.001) with an increase from the pre-pandemic to the initial phase (p < 0.001), followed by a steady decrease across both lockdowns, normalizing in November/December 2020. Female gender, high adjustment disorder symptom load at baseline and psychiatric comorbidities were risk factors for higher levels and an unfavorable course of psychosocial burden. Most psychiatric symptoms changed minimally, while resilience decreased over time (p = 0.044 and p = 0.037). The longitudinal course of psychosocial burden indicates an initial stress response, followed by a return to pre-pandemic levels even under recurrent lockdown conditions, mimicking symptoms of an adjustment disorder. Strategies for proactive, specific and continuous treatment have to address resilience capacities before their depletion in the pandemic aftermath, especially for patients with additional risk factors.

[The Cost of Early Diagnosis of Cognitive Decline in German Memory Clinics]. / Kosten der Diagnostik kognitiver Störungen in deutschen Gedächtnisambulanzen.

Dementias are expensive diseases: the net annual cost in European healthcare is about € 28.000 per case with a strong stage dependency, of which medical care accounts for about 19%. Diagnostic costs, on the other hand, account for only a small proportion of the total costs. With changes in the guidelines, biomarker tests are becoming increasingly important. At present, the concrete economic impact of biomarker-based diagnosis is largely unknown. To determine the actual costs of diagnostic procedures based on guidelines, we conducted a survey among the members of the German Memory Clinic Network (DNG). From 15 expert centres, the staff engagement time for all procedures was collected. Based on the individual engagement times of the different professions, the total of personnel costs for diagnostics was calculated using current gross personnel costs. The total sum of diagnostic costs (personnel plus procedures) was calculated for three different scenarios e. g. € 633,97 for diagnostics without biomarkers, € 1.214,90 for diagnostics with CSF biomarkers and € 4.740,58 € for diagnostics with FDG- plus Amyloid-PET. In addition, the actual diagnostic costs of the current practice in expert memory clinics were estimated, taking into account personnel costs, costs for the different procedures and the frequency of their use across all patients. This results in total average costs of € 1.394,43 per case as the mean across all centres (personnel costs € 351,72, costs for diagnostic procedures € 1.042,71). The results show that state-of-the-art diagnosis of dementia and pre-dementia states, such as mild cognitive impairment (MCI) requires financial resources, which are currently not fully reimbursed in Germany. The need for a biomarker-based etiological diagnosis of dementia and pre-dementia states will increase, due to availability of disease-modifying treatments. Therefore, the current gap of reimbursement must be filled by new models of compensation.

Current clinical practice of electroconvulsive therapy and repetitive transcranial magnetic stimulation in psychiatry, a German sample.

The purpose of the study was to evaluate the current clinical practice of Electroconvulsive Therapy and Repetitive Transcranial Magnetic Stimulation in German psychiatry. Case-based data (> 1.000.000 cases) were collected according to §21 of the German hospital remuneration law from January 2015 to December 2017. The study cohort comprises approximately 35-40% of the annual psychiatric cases and hospitals in Germany. Frequency of ECT and rTMS cases were investigated considering main diagnoses according to ICD-10 and treatment settings (inpatient vs. day-care). ECT cases with short-term hospitalization (≤ 4 days) were supposed to be maintenance ECT cases. A linear regression analysis was conducted to estimate trends in the use of ECT and rTMS. Different groups were compared using Chi-square tests. ECT and rTMS cases appear to increase in total during the observation period possibly due to facilities newly introducing ECT and rTMS but also to increased frequency of treatments. Both treatments were rarely performed in day-care settings (0.89% and 11.25%). ECT was performed in 1.72% of all cases with affective disorders and in 1.48% with major depressions, respectively. Age ≥ 65 years, females, severe and psychotic depression were significantly associated with a higher rate of ECT cases. > 40% of all ECT cases were possibly maintenance ECT cases. Only 0.60% of these were performed in day- care settings. rTMS was primarily performed in major depression (86,7% of all rTMS cases). This study suggests a growing demand for ECT and rTMS. Nevertheless, the use of ECT is still low compared to the high prevalence of treatment resistant depression. The use of rTMS is even lower and seems to be restricted to specialized institutions. Maintenance ECT is frequently carried out in an inpatient setting. Limitations of this study are the case- and group-based analysis, missing data on outpatient services and treatment sessions per case. Therefore, the database is not necessarily representative for the entire German healthcare system. Further studies are needed to verify the presented findings and should address the feasibility of ambulatory and day-care ECT services.

Prevalence of affective disorders and dementia in inflammatory polyarthropathies.

Comorbid disorders are common in psychiatric diseases and understanding the risk of secondary diseases can aid successful clinical treatment. The objective of this study was to compare the frequency of comorbid dementia, affective disorders, and inflammatory polyarthropathies. Healthcare data obtained via the German Hospital Fees Act from two independent databases with more than 7.4 million cases were analyzed to compare the prevalence of comorbid disorders. Comorbid inflammatory polyarthropathy was observed in 2.27% of patients diagnosed with affective disorders and 1.35% of patients with dementia (p < 0.001). Among patients with a primary diagnosis of inflammatory polyarthropathy, 1.27% of patients were diagnosed with dementia, whereas 4.55% of age-matched patients without inflammatory polyarthropathies had comorbid dementia (p < 0.001). The opposite effect was demonstrated for affective disorders, as 5.77% of patients with a primary diagnosis of inflammatory polyarthropathy also had comorbid affective disorders, while 4.87% of age-matched patients without inflammatory polyarthropathy had an accompanying affective disease (p < 0.001). These findings show an association between the occurrence of inflammatory polyarthropathies, dementia, and affective disorders. This correlation might improve diagnosis and treatment for patients with comorbidities. Moreover, further exploration of the molecular pathophysiology underlying these relationships could be relevant for the development of novel treatment options.

Promoting stigma coping and empowerment in patients with schizophrenia and depression: results of a cluster-RCT.

There is a need for interventions supporting patients with mental health conditions in coping with stigma and discrimination. A psycho-educational group therapy module to promote stigma coping and empowerment (STEM) was developed and tested for efficacy in patients with schizophrenia or depression. 30 clinical centers participated in a cluster-randomized clinical trial, representing a broad spectrum of mental health care settings: in-patient (acute treatment, rehabilitation), out-patient, and day-hospitals. As randomized, patients in the intervention group clusters/centers received an illness-specific eight sessions standard psychoeducational group therapy plus three specific sessions on stigma coping and empowerment ('STEM'). In the control group clusters the same standard psychoeducational group therapy was extended to 11 sessions followed by one booster session in both conditions. In total, N = 462 patients were included in the analysis (N = 117 with schizophrenia spectrum disorders, ICD-10 F2x; N = 345 with depression, ICD-10 F31.3-F31.5, F32-F34, and F43.2). Clinical and stigma-related measures were assessed before and directly after treatment, as well as after 6 weeks, 6 months, and 12 months (M12). Primary outcome was improvement in quality of life (QoL) assessed with the WHO-QOL-BREF between pre-assessment and M12 analyzed by mixed models and adjusted for pre-treatment differences. Overall, QoL and secondary outcome measures (symptoms, functioning, compliance, internalized stigma, self-esteem, empowerment) improved significantly, but there was no significant difference between intervention and control group. The short STEM module has proven its practicability as an add-on in different settings in routine mental health care. The overall increase in empowerment in both, schizophrenia and depression, indicates patients' treatment benefit. However, factors contributing to improvement need to be explored.The study has been registered in the following trial registers.

Nuclear medical imaging as part of dementia diagnostics in psychiatric day-care clinics and inpatient care settings.

BACKGROUND: Current guidelines support the use of nuclear medical imaging (NMI) techniques for differential diagnostics of certain cases of dementia. AIMS: We aimed at studying the association between using NMI and the accuracy of dementia diagnoses. Additionally, we evaluated the effect of conducting NMI on the duration of hospital treatment. METHODS: This study was based on data collected according to §21 of the German hospital remuneration law, including relevant diagnostic and procedural codes for NMI in dementia patients. In total, more than 7.2 million cases treated in German psychiatric and somatic hospitals between 2015 and 2017 were included. Associations between the frequency of NMI and the accuracy of dementia diagnoses in terms of specific vs. unspecific diagnostic codes were analyzed using Fischer's exact test. RESULTS: In total, 351,106 cases with a dementia diagnosis were encoded during the study period. NMI was performed in 1.03% or 0.15% of all patients with dementia in psychiatric or somatic clinics, respectively. In psychiatric clinics, the proportion of unspecific dementia diagnoses decreased from 20.86% in 2015 to 17.73% in 2017. NMI was mainly performed within psychiatric day-care settings. Interestingly, patients receiving NMI stayed shorter within day-care settings (8.1 ± 16.0 days) compared to inpatient settings (38.3 ± 44.7 days). CONCLUSIONS: Nuclear medical imaging is often performed in psychiatric day-care settings. Further studies are warranted to understand the predictive diagnostic value of NMI in dementia diagnosis compared with clinical, CSF and structural imaging in different healthcare settings.

[Day care/inpatient psychiatric treatment of minors and adults with hyperkinetic disorder in German psychiatric hospitals : Basic conditions, diagnoses and comorbidities]. / (Teil-)stationäre Therapie von Voll- und Minderjährigen mit einer hyperkinetischen Störung in der deutschen Psychiatrie : Rahmenbedingungen, Diagnosevergabe und Komorbiditäten.

BACKGROUND: Hyperkinetic disorders (HKD, ICD-10 F90.­) have increasingly been the focus of research literature in recent years. Empirical studies analyzing the care situation in psychiatric clinics are so far primarily available for a few health insurances. This study analyzed a German sample from 2015 consisting of inpatient as well as day care psychiatric treatment cases from all statutory health insurances focusing on the care situation and differentiating between minor vs. adult patients with the main diagnosis HKD. MATERIAL AND METHODS: The study was based on the treatment relevant indicators in psychiatry and psychosomatics (VIPP) database, which contains data according to §21 of the Hospital Remuneration Act (KHEntgG). A total of 896 treatment cases with the diagnosis of HKD from the year 2015, based on anonymized routine records from 41 psychiatric clinics, were analyzed. RESULTS: The basic conditions for inpatient/day care psychiatric treatment significantly differed between minor vs. adult patients. Minors travelled greater distances to the treatment site, received more therapy units and stayed longer in the psychiatric clinic than adults. Significant differences were also found between the subgroups concerning the main diagnoses according to ICD-10 coding as well as comorbid mental disorders. CONCLUSION: Due to greater distances from their residence to a psychiatric hospital for minors, extension of capacities with a focus on child and youth psychiatry seems to be a reasonable conclusion. Simultaneously, the intensity of treatment seems to be lower for adult patients, despite a greatly increased number of secondary diagnoses and thus anticipated psychological stress. Transition difficulties from child and youth psychiatry to adult psychiatry may be a possible explanation for this discrepancy.

[Vagus Nerve Stimulation for Affective Disorders]. / Vagusnervstimulation bei affektiven Störungen.

Vagus nerve stimulation (VNS) is a minimally invasive neurostimulation method and was approved for drug-resistant epilepsy in children and adults in Europe in 1994. The observation that depression -the most common comorbidity in epilepsy - improved with VNS prompted trials of VNS in treatment-resistant depression (TRD) leading to European approval of VNS for TRD in 2001. Use of VNS for TRD patients in Germany is currently limited to a few highly specialized tertiary centers and the method is largely unknown in psychiatric clinical practice. We therefore systematically review the most recent publications on VNS in TRD as well as recommendations in guidelines and discuss the use of VNS in clinical practice. In the past 5 years, 5 level-2 studies and 4 level-3 studies were published on the effect of VNS in TRD patients. Clinical studies have failed to demonstrate short-term efficacy of VNS in TRD patients. Long-term efficacy of VNS in TRD patients is documented by multiple studies: the recently published largest ever investigation on the subject confirms favorable outcomes in TRD patients receiving adjunctive VNS in addition to treatment-as-usual compared to patients receiving treatment-as-usual-only over a 5-year period. Long-term efficacy of VNS is documented by level-2 evidence; however, it is not known which TRD patients have a higher probability of responding to VNS, which may complicate patient selection in clinical practice. Additionally, the unclear and variable definition of TRD may hinder or postpone adequate use of neurostimulation treatments.

Cardiovascular and metabolic comorbidities in patients with Alzheimer's disease and vascular dementia compared to a psychiatric control cohort.

BACKGROUND: Multimorbidity in dementia is associated with an increased risk of complications and a higher need for care. Having knowledge of cardiovascular and metabolic comorbidities is crucial when making decisions about diagnostic procedures and therapies. We compared the prevalence of comorbidities in hospitalized patients with Alzheimer's disease (AD), vascular dementia, and psychiatric diseases other than dementia. Additionally, we compared clinically relevant health-care indicators (length of hospital stay, rate of re-hospitalization) between these groups. METHODS: We used information from a database of treatment-relevant indicators from psychiatric and psychosomatic hospitals throughout Germany. This database contains routinely recorded data collected from 85 German hospitals from 2011 to 2015. In total, 14 411 AD cases, 7156 vascular dementia cases, and 34 534 cases involving non-demented psychiatric patients (used as controls) were included. To analyze comorbidities and health-care indicators, χ2 tests and t-tests were used. RESULTS: Diabetes mellitus, lipoprotein disorders, coronary artery diseases, cardiac arrhythmia and insufficiency, and atherosclerosis were significantly more prevalent in patients with vascular dementia than in those with AD and psychiatric controls. Hypertension and coronary artery diseases were less frequently associated with AD than with non-demented psychiatric controls (P < 0.001). Additionally, dementia patients with cardiovascular or metabolic diseases exhibited longer hospital stays (+ 1.4 days, P < 0.001) and were more often re-hospitalized within 3 weeks (P < 0.001) and 1 year (P < 0.001) compared to dementia patients without these comorbidities. CONCLUSIONS: Awareness of somatic comorbidities in patients with dementia is crucial to avoid complications during inpatient treatment. The occurrence of comorbid disorders was associated with longer and more frequent hospital stays, which potentially lead to higher health-care costs. Further studies should evaluate the causative association between somatic comorbidities and inpatient costs in dementia patients.

Transcutaneous noninvasive vagus nerve stimulation (tVNS) in the treatment of schizophrenia: a bicentric randomized controlled pilot study.

Despite many pharmacological and psychosocial treatment options, schizophrenia remains a debilitating disorder. Thus, new treatment strategies rooted in the pathophysiology of the disorder are needed. Recently, vagus nerve stimulation (VNS) has been proposed as a potential treatment option for various neuropsychiatric disorders including schizophrenia. The objective of this study was to investigate for the first time the feasibility, safety and efficacy of transcutaneous VNS in stable schizophrenia. A bicentric randomized, sham-controlled, double-blind trial was conducted from 2010 to 2012. Twenty schizophrenia patients were randomly assigned to one of two treatment groups. The first group (active tVNS) received daily active stimulation of the left auricle for 26 weeks. The second group (sham tVNS) received daily sham stimulation for 12 weeks followed by 14 weeks of active stimulation. Primary outcome was defined as change in the Positive and Negative Symptom Scale total score between baseline and week 12. Various other secondary measures were assessed to investigate safety and efficacy. The intervention was well tolerated with no relevant adverse effects. We could not observe a statistically significant difference in the improvement of schizophrenia psychopathology during the observation period. Neither psychopathological and neurocognitive measures nor safety measures showed significant differences between study groups. Application of tVNS was well tolerated, but did not improve schizophrenia symptoms in our 26-week trial. While unsatisfactory compliance questions the feasibility of patient-controlled neurostimulation in schizophrenia, the overall pattern of symptom change might warrant further investigations in this population.

Changing the Antipsychotic in Early Nonimprovers to Amisulpride or Olanzapine: Randomized, Double-Blind Trial in Patients With Schizophrenia.

BACKGROUND AND HYPOTHESIS: Meta-analyses have shown that the majority of patients with schizophrenia who have not improved after 2 weeks of treatment with an antipsychotic drug are unlikely to fully respond later. We hypothesized that switching to another antipsychotic with a different receptor binding profile is an effective strategy in such a situation. STUDY DESIGN: In total, 327 inpatients with an acute exacerbation of schizophrenia were randomized to double-blind treatment with either olanzapine (5-20 mg/day) or amisulpride (200-800 mg/day). Those patients who had not reached at least 25% Positive-and-Negative-Syndrome-Scale (PANSS) total score reduction from baseline after 2 weeks (the "non-improvers") were rerandomized double-blind to either staying on the same compound ("stayers") or to switching to the other antipsychotic ("switchers") for another 6 weeks. The primary outcome was the difference in the number of patients in symptomatic remission between the combined "switchers" and the "stayers" after 8 weeks of treatment, analyzed by logistic regression. STUDY RESULTS: A total of 142 nonimprovers were rerandomized at week two. 25 (45.5 %) of the 'stayers' compared to 41 (68.3 %) of the "switchers" reached remission at endpoint (p = .006). Differences in secondary efficacy outcomes were not significant, except for the PANSS negative subscore and the Clinical-Global-Impression-Scale. "Switchers" and "stayers" did not differ in safety outcomes. CONCLUSIONS: Switching "non-improvers" from amisulpride to olanzapine or vice-versa increased remission rates and was safe. The superiority in the primary outcome was, however, not paralleled by significant differences in most secondary efficacy outcomes and the effect was only apparent at the last visit making replications of longer duration necessary.

Time to Treatment Discontinuation in German Patients with Schizophrenia: Long-Acting Injectables versus Oral Antipsychotics.

BACKGROUND AND OBJECTIVE: Long-acting injectable antipsychotics (LAIs) are associated with better treatment adherence and persistence than oral antipsychotics (OAPs) in patients with schizophrenia. However, real-world evidence assessing the impact of treatment with LAIs in Germany is limited. To fill this gap, we compared antipsychotic medication adherence and risk of treatment discontinuation (TD) among schizophrenia patients newly initiated on LAI or who switched their OAP regimen (overall cohort; OC). METHODS: Claims data of German schizophrenia patients who initiated LAIs or switched their OAP during 2012-2016 (index date) were retrospectively analyzed. Treatment switch was defined as add-on medication to existing prescription or terminating the existing prescription and initiating another OAP. Adherence and time to treatment discontinuation (TTD) were estimated. Determinants of treatment discontinuation were analyzed using two Cox regression models. Model 1 controlled for age, sex, and Charlson Comorbidity Index (CCI); model 2 also included insurance status, and medication, visit, and psychiatric inpatient stay costs. Sensitivity analysis on patients who terminated existing prescriptions and initiated new OAPs (complete switch cohort; CSC) was performed. RESULTS: In OC (n = 2650), LAI users had better adherence (35.4% vs. 11.6%), persistence (no 60-day gap; 40.7% vs. 19.8%), and longer TTD (median [95% confidence interval (CI)] 216 [193-249] vs. 50 [46-56] days) than OAP users. OAP usage (hazard ratio [HR] 1.89, 95% CI 1.73-2.06; p < 0.001) and greater CCI (HR 1.04, 95% CI 1.00-1.07; p = 0.023) were associated with greater risk of TD in model 1. Model 2 showed similar results. LAI users in CSC also had better adherence, persistence, and longer TTD. In CSC too, OAP usage and greater CCI were associated with greater risk of TD in model 1, but only CCI was significant in model 2. Higher pre-index psychiatric inpatient costs were associated with lower risk of TD (HR 0.99, 95% CI 0.98-1.00; p = 0.014). LIMITATIONS: Inherent limitations of claims data and lack of control on OAP administration may have influenced the results. CONCLUSION: This real-world study associates LAIs with better medication adherence and lower antipsychotic discontinuation risk than OAPs.

Hospitalization Rates and Therapy Costs of German Schizophrenia Patients Who are Initiated on Long-Acting Injectable Medication: A Mirror-Image Study.

BACKGROUND: Long-acting injectable (LAI) antipsychotics can reduce relapse, hospitalization, and costs in patients with schizophrenia. However, real-world evidence assessing the impact of treatment with LAIs in Germany is limited. OBJECTIVE: To provide updated evidence on the impact of LAI initiation on hospitalization rates and therapy costs. METHODS: Using a mirror-image design, claims data of 850 German patients with schizophrenia who initiated treatment with LAIs during 2013-2015 was retrospectively analyzed. For the included patients, costs and resource utilization were compared for the 12 months before the index date (first initiation of LAI) and the 12 months after the index date. Annual treatment costs, hospitalization rates, ambulatory visits, sick leaves and medical aids were assessed. Two models were used to evaluate hospitalization and its costs. In model 1, hospitalization during the index date (first LAI prescription in 2013-2015) was allocated to the "pre-" time interval, while in model 2 it was neither attributed to the pre- nor to the post-index date. Regression analysis was performed to identify patients who benefited the most in terms of cost reduction from LAI initiation. RESULTS: Medication costs were significantly higher post-switching to LAI compared with pre-switching period (€3832 vs €799; p < 0.001). In model 1, number of hospitalizations, days hospitalized, and associated costs were significantly lower post-switching compared with pre-switching (2.3 vs 2.6; 59.2 vs 73.4; and €5355 vs €11,908, respectively; all p < 0.001). Similar results were obtained for costs in model 2 (€5355 vs €10,276; p < 0.001). Mean total costs reduced significantly from pre-switching to post-switching period in model 1 (€13,776 vs €10,418; p < 0.001). Patients with characteristics such as higher number of non-psychiatric and psychiatric inpatient stays during the pre-index period (all p < 0.05) benefited the most from cost reduction after LAI initiation. CONCLUSION: In this cohort of German patients with schizophrenia, treatment initiation with LAI resulted in reduced hospitalization rates and total costs.

Claims Data Analysis on the Dispensing of Tricyclic Antidepressants Among Patients With Dementia in Germany.

Objective: A restrictive use of tricyclic antidepressants (TCA) in patients with dementia (PwD) is recommended due to the hazard of anticholinergic side effects. We evaluated the frequency of TCA dispensing in PwD over a period of 1 year and the use of TCA before and after the incident diagnosis of dementia. Methods: This analysis was based on administrative data from a German statutory health insurance for a period of 2 years. Totally, 20,357 patients with an incident diagnosis of dementia in 2014 were included. We evaluated the dispensing of TCA in 2015. Subgroup analyses were conducted to evaluate associations between the incident diagnosis of dementia and modifications in TCA dispensing. Results: In 2015, 1,125 dementia patients (5.5%) were treated with TCA and 31% were medicated with TCA in all four quarters of 2015. Most dispensings were conducted by general practitioners (67.9%). On average, patients received 3.7 ± 2.6 dispensings per year. Amitriptyline (56.3%), doxepin (26.8%), and trimipramine (16.8%) were dispensed most often. Subgroup analyses revealed that the dispensing of TCA remained mainly unchanged following the incident diagnosis. Conclusion: A relevant number of PwD were treated with TCA. To maintain the patients' safety, an improved implementation of guidelines for the pharmaceutical treatment of PwD in healthcare institutions might be required. Since 68% of the patients suffered from depression, future studies should further evaluate the indications for TCA.

Bacterial infections among patients with psychiatric disorders: Relation with hospital stay, age, and psychiatric diagnoses.

The prevalence of infections is supposed to be higher in older patients and to extend the length of hospital stays. This study aimed, first, to test this supposition within a large psychiatric population which we divided into four clusters of psychiatric ICD-10 diagnoses: F00-F03 (dementias), F10 (substance disorders), F20-29 (schizophrenia, schizophreniform and other non-mood psychotic disorders), F32-F33 (major depressive disorders). Second, despite the increasing evidence for the role of infections in psychiatric disorders, it is, to the best of our knowledge, largely unknown whether the rates of infections with pathogens of the four most frequent germ families differ between psychiatric diseases. Thus, in a retrospective study, the results of clinical routine examinations (pap smear, analysis of midstream urine, stool) dependent on symptoms in 8545 patients of a German psychiatric clinic were analyzed in a 12-year dataset. Results show that a longer hospital stay was associated with an increased number of microbiological tests, but led to no significant difference between positive vs. negative findings. Consistent with previous studies, patients with infections were older than patients without infections. For the F10 diagnosis cluster we found a significantly reduced (F10: Staphylococcaceae) and for the F20-29 cluster a heightened risk of infections (Staphylococcaceae, Corynebacteriaceae). Furthermore, patients belonging to the F00-F03 cluster exhibited elevated rates of infections with all four germ families. The latter can be ascribed to patients' age as we found higher age to be associated with these infections, independently of the presence of dementia. Our results suggest that different psychiatric diagnoses are associated with a heightened or lowered risk of bacterial infections and, furthermore, that clinical routine infection-screenings for elderly psychiatric patients seems to be reasonable.

Continuity of treatment with benzodiazepines in dementia patients: an analysis of German health insurance claims data.

Long-term treatment with benzodiazepines (BZD) should be avoided in dementia patients because of an increased risk of adverse events. We evaluated how continuously dementia patients were prescribed BZD over 12 months. For this observational study, we used claims data from a large German public sickness fund for 2014 and 2015, including patients with an incident diagnosis of dementia in 2014. The aim was to evaluate the continuity of treatment, the frequency of BZD prescriptions and defined daily doses were evaluated. In total, 1298 (5.6%) patients received 4.7±5.2 BZD prescriptions in 2015 on average. Thereof, lorazepam (47.5%), oxazepam (18.6%), diazepam (14.5%), and bromazepam (12.2%) were most often prescribed. 30.7% of the patients received at least one BZD prescription in each quarter of 2015. Although the total number of patients receiving BZD decreased in 2015, defined daily doses for single substances remained mainly unchanged. The incident diagnosis of dementia was not associated with modifications of prescription behavior. The treatment with BZD was not discontinued in a large proportion of dementia patients, increasing the risk of adverse events. Physicians' awareness of avoiding BZD should be improved and further evidence for the appropriate treatment of psychiatric symptoms in dementia (e.g. sleep disturbances, anxiety) is required.

[Diagnosis of Metabolic Risk Factors in Psychiatric Inpatients]. / Diagnostik metabolischer Risikofaktoren bei stationär-psychiatrischen Patienten.

OBJECTIVE: Individuals suffering from mental illness have one to two decades reduced life expectancy. The increased morbidity and mortality is mainly due to cardiometabolic disorders. Despite these numbers, international studies give evidence that diagnoses and treatment of metabolic risk factors in psychiatric patients is insufficient. We assume that in Germany metabolic risk factors are also underdiagnosed and insufficiently treated. METHODS: We tested for the frequency of diagnoses of the metabolic risk factors obesity, nicotine dependence and abuse, disorders of lipid metabolism, hypertension and diabetes in 139 307 cases of residential treatment and semi-residential care in 47 psychiatric hospitals in Germany in the year 2012. Data were derived from the VIPP(indicators of treatment quality in psychiatry and psychosomatic medicine)-project, a project that comprises the routine data of psychiatric hospitals, that are sent to the InEK (institute for the lump sum payment system for hospitals). Frequencies were compared with prevalence of metabolic risk factors in the German population and prevalences of metabolic risk factors found in psychiatric patients in international studies. RESULTS: In particular obesity (2.8 %), disorders of lipid metabolism (2.8 %) and nicotin dependence (4.2 %) were underdiagnosed. We assume that also diabetes (6.8 %) and hypertension (17.7 %) were underdiagnosed. CONCLUSION: The results give evidence that metabolic risk factors are underdiagnosed and possibly insufficiently treated in German psychiatric hospitals. We cannot exclude that the results might also be due to poor documentation. It remains to be seen if the introduction of the PEPP (the new lump sum payment system in German psychiatry) will heighten the level of attention for metabolic risk factors and their treatment.

[Incidence and Costs of 1:1 Care in Psychiatric Hospitals in Germany - A Descriptive Analysis Based on the VIPP Project Data Set]. / Häufigkeit und Kosten der 1:1-Betreuung in der Erwachsenenpsychiatrie in Deutschland - Eine deskriptive Analyse anhand des VIPP-Datensatzes.

OBJECTIVE: 1:1 care is applied for patients requiring close psychiatric monitoring and care like patients with acute suicidality. The article describes the frequency of 1:1 care across different diagnoses and age groups in German psychiatric hospitals. METHODS: The analysis was based on the VIPP Project from the years 2011 and 2012. A total of 47 hospitals with more than 120,000 cases were included. Object of the analysis was the OPS code 9-640.0 1:1 care. The evaluation was performed on case level. RESULTS: Data of 47 hospitals were included. Of the 121,454 cases evaluated in 2011 3.8 % documented a 1:1 care within the meaning of OPS 9-640.0 additional code. Of the 66 245 male cases a 1:1 care was documented in 3.5 % and the 55 207 female cases was 4.1 %. Compared to 2011, the proportion of 1:1 care in 2012 rose to 4.8 %. CONCLUSION: The results show that 1:1 care is frequently applied in German psychiatric hospitals. The Data of the VIPP project have proven to be a useful tool to gain information on the frequency of cost-intensive interventions in German psychiatric hospitals. Further analyses should create the possibility of evaluation at the level of the individual codes.
