Do the elderly and those with comorbid chronic physical conditions have improved access to outpatient psychotherapy post structural reforms in Germany? Results of the ES-RiP study

Background

In 2017, a reform of the German outpatient psychotherapy guideline was carried out, aiming to reduce waiting times and facilitate low-threshold access. This study analyzes the extent to which the implementation of the two new service elements 'psychotherapeutic consultation times' and 'acute short-term psychotherapeutic interventions' improved psychotherapeutic care for patients with mental disorders and chronic physical conditions (cMPs), for patients with mental disorders without chronic physical conditions (MnoP), and elderly patients.

Methods

In a quantitative secondary analysis, we analyzed health insurance data of patients with psychotherapy billing codes obtained from the National Association of Statutory Health Insurance Physicians (KBV) for the years 2015-2019, evaluating descriptive statistical parameters for specific patient groups and care services.

Results

Between 2015 and 2019, the number of mentally ill receiving psychotherapy at least once in the corresponding year increased by 30.7%. Among these, the proportion of cMPs-patients increased from 26.8% to 28.2% (+1.4%), while that of MnoP-patients decreased from 68.3% to 66.4% (-1.9%). The number of elderly people receiving treatment also increased.

Conclusion

Since increases and decreases in the percentage shares occur evenly over the years investigated, it is questionable whether the reform in 2017 has had a direct influence on these changes.

Effect of the addition of a mental health specialist for evaluation of undiagnosed patients in centres for rare diseases (ZSE-DUO): a prospective, controlled trial with a two-phase cohort design

Background

People with complex symptomatology but unclear diagnosis presenting to a centre for rare diseases (CRD) may present with mental (co-)morbidity. We hypothesised that combining an expert in somatic medicine with a mental health specialist working in tandem will improve the diagnostic outcome.

Methods

Patients aged 12 years and older who presented to one of the 11 participating German CRDs with an unknown diagnosis were recruited into this prospective cohort trial with a two-phase cohort design. From October 1, 2018 to September 30, 2019, participants were allocated to standard care (SC, N = 684), and from October 1, 2019 to January 31, 2021 to innovative care (IC, N = 695). The cohorts consisted mainly of adult participants with only a minority of children included (N = 67). IC included the involvement of a mental health specialist in all aspects of care (e.g., assessing medical records, clinic visits, telehealth care, and case conferences). Clinicaltrials.gov identifier: NCT03563677.

Findings

The proportion of patients with diagnoses established within 12 months after the first visit to the CRD explaining the entire symptomatology (primary outcome) was 19% (N = 131 of 672) in the SC and 42% (N = 286 of 686) in the IC cohort (OR adjusted for centre effects 3.45 [95% CrI: 1.99-5.65]). The difference was mainly due to a higher prevalence of mental disorders and non-rare somatic diseases in the IC cohort. The median time to explaining diagnoses was one month shorter with IC (95% CrI: 1-2), and significantly more patients could be referred to local regular care in the IC (27.5%; N = 181 of 659) compared to the SC (12.3%; N = 81 of 658) cohort (OR adjusted for centre effects 2.70 [95% CrI: 2.02-3.60]). At 12-month follow-up, patient satisfaction with care was significantly higher in the IC compared to the SC cohort, while quality of life was not different between cohorts.

Interpretation

Our findings suggested that including a mental health specialist in the entire evaluation process of CRDs for undiagnosed adolescents and adults should become an integral part of the assessment of individuals with a suspected rare disease.

Funding

The study was funded by the Global Innovation Fund from the Joint Federal Committee in Germany (Innovationsfonds des Gemeinsamen Bundesausschusses), grant number 01NVF17031.

Psychometric properties and normative values of the revised demoralization scale (DS-II) in a representative sample of the German general population

BACKGROUND

Demoralization is a clinically relevant syndrome in chronic diseases. The demoralization scale (DS-II) was recently developed as an economic screening tool in clinical populations. Main aim of this study was to provide normative data of DS-II scores in the general population.

METHODS

We developed a new German version, the DS-II Münster, and tested internal consistency as well as the previously proposed two-factor structure with confirmatory factor analyses. The DS-II was applied in a household survey of the general population. Associations between DS-II scores and age, gender and other sociodemographic variables were explored.

RESULTS

The final sample consisted of N = 2471 participants (mean age = 49.8 years, range: 18-96; 50.1% men, 49.8% women). The DS-II Münster showed nearly excellent internal consistency. The model fit indices of the two-factor structure were not superior to those of the one-factor model. Mean scores of the DS-II were as follows. Total score: M = 3.76 (SD = 5.56), Meaning and Purpose subscale: M = 1.65 (SD = 2.77), Distress and Coping Ability subscale: M = 2.11 (SD = 3.02). DS-II scores were increased in women with an effect size of Cohen's d = 0.19. An age-related increase was specifically found for the Meaning and Purpose subscale (d = 0.21).

CONCLUSIONS

The study provides normative values of the DS-II with respect to age and gender in the general population to facilitate interpretation of DS-II scores in clinical samples. A DS-II total score > 5 is suggested as a cut-off value. The findings further our understanding of significant symptom burden that was previously suggested in young patients with cancer.

Evaluating effects of the structural reform of outpatient psychotherapy for patients with mental disorders in Germany: comparing patients with and without comorbid chronic physical condition - rationale and study protocol of the ES-RiP project

INTRODUCTION

In 2017, in Germany, a structural reform of the outpatient psychotherapy guideline took place, aiming to reduce waiting times, to facilitate flexible low-threshold access (eg, general reachability by phone) and to lower access barriers for specific patient groups. The reform included new service elements, such as the implementation of additional psychotherapeutic consultations, acute short-term psychotherapeutic interventions and relapse prophylaxis as well as the promotion of group therapies, the facilitation of psychotherapists' availability, and the installation of appointment service centres. The ES-RiP project aims to thoroughly evaluate the effects of the reform with a special focus on patients with a comorbidity of mental disorders and chronic physical conditions (cMPs) compared with patients with a mental disorder but no long-term physical condition (MnoP). The project aims to evaluate (a) the extent to which the reform goals were achieved in the large group of patients with cMPs compared with MnoP, (b) the barriers that might hinder the implementation of the new guideline and (c) the procedures required for further developing and improving outpatient psychotherapy.

METHODS AND ANALYSIS

A mixed-methods design (quantitative, qualitative) along with a multilevel approach (patients, service providers, payers) triangulating several data sources (primary and secondary data) will be applied to evaluate the reform from different perspectives.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the coordinating committee as well as one local ethics committee, Justus Liebig University Giessen and Marburg - Faculty of Medicine (approval number: AZ 107/20) and Heidelberg (approval number: S-466/2020). The results of this study will be disseminated through expert panels, conference presentations and publications in peer-reviewed journals.

Dual guidance structure for evaluation of patients with unclear diagnosis in centers for rare diseases (ZSE-DUO): study protocol for a controlled multi-center cohort study

Background

In individuals suffering from a rare disease the diagnostic process and the confirmation of a final diagnosis often extends over many years. Factors contributing to delayed diagnosis include health care professionals' limited knowledge of rare diseases and frequent (co-)occurrence of mental disorders that may complicate and delay the diagnostic process. The ZSE-DUO study aims to assess the benefits of a combination of a physician focusing on somatic aspects with a mental health expert working side by side as a tandem in the diagnostic process.

Study design

This multi-center, prospective controlled study has a two-phase cohort design.

Methods

Two cohorts of 682 patients each are sequentially recruited from 11 university-based German Centers for Rare Diseases (CRD): the standard care cohort (control, somatic expertise only) and the innovative care cohort (experimental, combined somatic and mental health expertise). Individuals aged 12 years and older presenting with symptoms and signs which are not explained by current diagnoses will be included. Data will be collected prior to the first visit to the CRD’s outpatient clinic (T0), at the first visit (T1) and 12 months thereafter (T2).

Outcomes

Primary outcome is the percentage of patients with one or more confirmed diagnoses covering the symptomatic spectrum presented. Sample size is calculated to detect a 10 percent increase from 30% in standard care to 40% in the innovative dual expert cohort. Secondary outcomes are (a) time to diagnosis/diagnoses explaining the symptomatology; (b) proportion of patients successfully referred from CRD to standard care; (c) costs of diagnosis including incremental cost effectiveness ratios; (d) predictive value of screening instruments administered at T0 to identify patients with mental disorders; (e) patients’ quality of life and evaluation of care; and f) physicians’ satisfaction with the innovative care approach.

Conclusions

This is the first multi-center study to investigate the effects of a mental health specialist working in tandem with a somatic expert physician in CRDs. If this innovative approach proves successful, it will be made available on a larger scale nationally and promoted internationally. In the best case, ZSE-DUO can significantly shorten the time to diagnosis for a suspected rare disease.

Evaluating the structural reform of outpatient psychotherapy in Germany (ES-RiP trial) - a qualitative study of provider perspectives

Background

Access to outpatient mental healthcare can be challenging for patients. In Germany, a national structural reform was implemented in 2017 to accelerate and enhance access to outpatient psychotherapy and reduce waiting times. During the first phase of the study ‘Evaluation of a structural reform of the outpatient psychotherapy guideline (ES-RiP)’ and embedded into a process evaluation, the implementation was to be evaluated through assessing general practitioners’ (GPs) and psychotherapists’ (PTs) perspectives regarding utilization of provided new measures, and perceived potential for optimization. Particular focus was on patients with a comorbidity of mental disorders and chronic physical conditions (cMPs).

Methods

This exploratory cross-sectional qualitative study used on-site and online focus group discussions and semi-structured telephone interviews with GPs and outpatient PTs. Generated data were analyzed using thematic framework analysis. Descriptive statistics were used to analyze participant characteristics collected via a socio-demographic questionnaire.

Results

Perspectives on the structural reform were heterogenous. GPs and PTs considered the component of timely initial psychotherapeutic assessment consultations beneficial. GPs disapproved of their deficits in detailed information about the structural reform and exchange with outpatient PTs. Improvement suggestions included structured short information exchange and joint quality circles. The overall number of available outpatient PTs in rural areas was perceived as insufficient. For patients with cMPs, GPs saw patient barriers for therapy access and continuity in low intrinsic motivation, physical impediments and older age. PTs also saw patient challenges regarding low intrinsic motivation and keeping scheduled appointments. They considered post-reform administrative efforts to be high and reported that the regulations (conformity) lead to planning difficulties and financial losses. Reform elements were tailored to fit in with PTs key therapy areas. Stronger networking and joint lectures were suggested as remedy for the currently still limited exchange with GPs. Unlike the GPs, PTs emphasized that accepting patients into psychotherapeutic treatment was independent of a possibly present chronic physical disease.

Conclusions

The findings contribute to understanding the integration of the delivered structural reform into daily care processes and provide an indication about reached targets and potential improvements. Further phases of the ES-RiP study can build on the findings and broaden insights.

[Personnel assessment in psychiatry and psychotherapy : Results of a feasibility study on the platform model]

The topic of personnel assessment in psychiatry, psychotherapy and psychosomatics is currently of great importance in terms of health policy. Sufficient empirical evidence for the development of a comprehensive system for staffing is not yet available. The platform model developed by the psychiatric psychosomatic societies and associations pursues a combined empirical normative approach for a future-oriented assessment instrument for the various professional groups. The concept presented has been proven in the health policy discussion as a sensible system of comprehensive personnel assessment; however, an empirically sound control is still lacking as to whether this system can be used practically for the task described and thus can withstand the task of a resilient and future-proof measurement instrument for the necessary personnel. The task of the present study was to examine the extent to which the assumptions of the platform model are confirmed, whether methodological indications can be identified and whether there are limitations of the study that can be used in the validation and foundation of the model. The study confirmed the feasibility of the model and refers to a number of methodological findings and limitations that can be used for the further development of the model. The developed model allows the necessary staffing to be derived and justified, regardless of diagnoses and settings. It is future-oriented and dynamic.

Individual and Needs-Based: The Platform-Model for Personnel Allocation in Child and Adolescent Psychiatry and Psychotherapy

Objective: An initiative by scientific societies of psychiatry, child and adolescent psychiatry, psychosomatic medicine, and further associations established the Platform-Model for the development of a needs-based system for adequate personnel allocation in psychiatric inpatient and day clinic units. We present the development of the instrument and a pilot study to identify feasibility and limitations. Methods: The basis of the study was a threefold methodological approach. Paradigmatic case vignettes adequately reflecting symptomatology and circumstances were described and validated, working profiles were generated and validated, and a matrix representing different needs-based dimensions was developed. Through reference date surveys, patients were assigned to needs-based clusters and Psych-PV categories. The required treatment effort under consideration of guidelines or expert consensus was estimated in several rounds of expert panels (Delphi method). Results: The pilot study proves the feasibility of the Platform-Model. Methodological findings as well as limitations of the model were identified in order to further develop the Platform-Model. Conclusions: The Platform-Model cannot serve as a tool to describe clinical pathways, but it appears to be an adequate and practical tool for assessment of the required staffing level based on patient needs independent of diagnosis and setting.

Psychiatric disorders after an accident: Predictors and the influence of the psychiatric condition prior to an accident

Background

The goal of this study is to assess prevalence and incidence of psychiatric sequelae in a sample of inpatient accident survivors. Such an attempt to assess psychiatric conditions that originate due to an accident seems to be important; this does not include psychiatric conditions already present prior to the accident.

Method

208 accident victims were consecutively examined over a period of 12 months using DSM-IV diagnostic assessment, CAPS, and self-evaluating questionnaires as well as ISS for injury severity. A predictor model for psychiatric disorders was set up.

Results

Incidence of newly developed Axis I disorders in our sample was 14.2% (6 months) and 12.3% (12 months). Incidence of PTSD was 5.9% (6 months) and 2.5% (12 months). Comorbidity was a general phenomenon. The psychiatric condition prior to the accident could be identified as a predictor for the development of Axis I disorders. The subjectively evaluated intensity of experienced threat to life and female gender were the main predictors for the development of PTSD.

Conclusions

Accidents can lead to different psychiatric disorders. PTSD as a single diagnosis is rare. Without taking into account pre-existing disorders, the incidence may be overestimated. Two predictor models for the development of PTSD and other mental disorders are presented.

Criteria Suggestive of Psychological Components of Itch and Soma-toform Itch: Study of a Large Sample of Patients with Chronic Pruritus

While psychological factors are relevant in many patients with chronic pruritus, not all patients can be offered psychologic, psychosomatic or psychiatric consultation. The aim of this exploratory study was to identify criteria suggestive of psychological factors relevant for the etiology of chronic pruritus and of somatoform pruritus. Routine data from the database of the Center for Chronic Pruritus of the University Hospital Münster were used, including the Neuroderm Questionnaire, Dermatology Life Quality Index and Hospital Anxiety and Depression Scale. Chronic pruritus patients (n = 3,391) without a psychiatric diagnosis in their medical history were compared to the 331 chronic pruritus patients with diagnoses of “psychological factors associated with etiology and course of chronic pruritus” (ICD-10:F54) or “somatoform pruritus” (F45.8) confirmed by an expert. The latter reported more pruritus triggers, especially “strain” and “emotional tension” and used more emotional adjectives to describe their pruritus. They reported more often scratching leading to excoriations, higher levels of pruritus, impairment of quality of life, anxiety and depression. These aspects suggest the presence of psychological factors in the etiology of chronic pruritus and somatoform pruritus. Prospective validation, however, needs to be carried out.

[Psychometric Properties of the Shortend Version of the Scale "Transpersonal Trust" in a Representative Sample of the German Population]

INTRODUCTION

The aim of the present study was to show the development of the revised and shortened German version (6 items) of the scale "Transpersonales Vertrauen" (TPV-6R; 2017) as well as to examine its psychometric properties.

METHODS

In a representative German sample the questionnaire has been given to 2513 subjects. Collected data from 2464 subjects could be analysed. Exploratory and confirmatory factor analysis has been made to prove the original one-factor model (Belschner, 2000) as well as the 2-factorial structure found by Albani et al. (2003). Measurement invariance was tested using multigroup analysis. Correlations were used to determine convergent and discriminant validity towards other items.

RESULTS

After excluding 2 items due to their unsatisfactory scale fit, the 4 item model showed good item and scale characteristics as well as excellent model fit. The one factorial structure of the original work of Belschner and colleagues (2000) could be replicated. Metric invariance could be shown for gender and age, partial scalar invariance could be only generated for gender. No metric or scalar invariance could be shown for federal state and denomination.

DISCUSSION

Due to the good psychometric properties of the TPV-4R questionnaire it should be further analyzed in future research with other validated instruments that are measuring spiritual or religious attitudes.

CONCLUSIONS

The new German short version, the TPV-4R, is an economic, reliable and valid questionnaire to measure spiritual attitudes.

[Psychometric Properties of the Shortend Version of the "Systems of Belief Inventory" in a Representative Sample of the German Population]

INTRODUCTION

The aim of the present study was to show the development of the revised and shortened German version (6 items) of the "Systems of Belief Inventory" (SBI-6R-D) as well as to examine its psychometric properties.

METHODS

In a representative German sample the questionnaire has been given to 2513 subjects. A confirmatory factor analysis has been made to prove the original American factor structure. Measurement invariance was tested using multigroup analysis. Correlations were used to determine convergent and discriminant validity towards other items.

RESULTS

The SBI-6R-D showed good item and scale characteristics as well as good model fit. In difference to the work of Albani et al. (SBI-15R-D), the 2 factorial structure of the original American questionnaire could be replicated. Scalar invariance could be shown for gender and age, metric invariance for denomination and federal state.

DISCUSSION

Due to the good psychometric properties of the questionnaire it should be further analyzed in future research with other validated religious instruments.

CONCLUSIONS

The new German short version, the SBI-6R-D, is an economic, reliable and valid questionnaire to measure spiritual and religious attitudes.

Distraction From Itch Shows Brainstem Activation Without Reduction in Experimental Itch Sensation

The central processing of itch is not completely understood. This is the first study to use functional magnetic resonance imaging (fMRI) to examine the central modulation by distraction of experimentally induced itch. A total of 33 healthy volunteers were examined with fMRI. Periods of itch induction without distraction and itch with distraction by a Stroop task (psychological test, where the participants have to decide if the colour of the writing corresponds to the written word, for example if "red" is written in red or not) were counterbalanced during the scanning to examine task-specific changes in blood oxygenation level dependent-signal. The intensity of the subjects' itch sensation, desire to scratch and pain sensation were evaluated. Distraction by a Stroop task did not reduce itch intensity or urge to scratch. However, the Stroop task led to significantly higher activation of the left brainstem when it followed the "pure" itch sensation. Itch and pain seem to have similar inhibition pathways, particularly concerning brainstem activation during distraction. But as itch sensation, in contrast to pain, could not be sufficiently reduced by distraction, both entities might have different modulation systems.

Itch Perception and Skin Reactions as Modulated by Verbal Suggestions: Role of Participant's and Investigator's Sex

This study investigated sex-specific differences in itch perception and skin reactions, as modulated by verbal suggestions, and the role of the investigator's sex. Healthy volunteers (50 males, 50 females), divided into 4 groups, were tested by male and female investigators. Itch was induced via prick testing with sodium chloride and histamine in 4 runs; 2 control conditions (with no exaggerated verbal comments about expected itch) and 2 experimental conditions (with exaggerated verbal comments). After 5 min, wheal and flare reactions were measured and itch intensity was rated by subjects on a numerical rating scale. Exaggerated verbal suggestions resulted in higher itch intensity ratings in the sodium chloride and histamine condition, and higher unpleasantness ratings and a wheal of greater extent in the sodium chloride condition, as well as a flare of greater extent in the histamine condition. The magnitude of the differences between the exaggerated verbal suggestion conditions and respective control conditions was only significantly different between male and female investigators concerning flare size in the histamine condition. There were no differences between male and female participants. Therefore, sex differences may play only a minor role in nocebo-induced itch perception.

Relations between the characteristics and psychological comorbidities of chronic pruritus differ between men and women: women are more anxious than men

BACKGROUND

Although sex and gender are becoming more important in diagnostics and therapy, there is still little knowledge about sex-specific differences in chronic pruritus (CP).

OBJECTIVES

To compare, taking into consideration the characteristics of pruritus, sex-specific differences in psychological symptoms in patients with CP.

METHODS

Sociodemographic data, data on the clinical characteristics of the skin and CP were documented over a 1-year period in all patients attending the Competence Center Chronic Pruritus of the University Hospital Münster for the first time. All patients completed the Hospital Anxiety and Depression Scale. Student's t-tests for independent study groups and linear regression analyses were applied.

RESULTS

A total of 619 patients (278 men, 341 women) were included in the analysis. Women were more anxious than men, but were not more depressed. A linear regression analysis indicated that depression and anxiety scores in women were related to the average intensity of pruritus during the previous 4 weeks and to a more generalized pruritus at the beginning of CP; older age in women also correlated with the scores on the depression subscale. Interestingly, the associations were different in men: scores on the depression scale were associated with the diagnosis of CP pruritus with multiple scratch lesions.

CONCLUSIONS

There are sex-specific differences in the relationship between the psychological symptoms and clinical characteristics of CP; higher anxiety scores were achieved by women. Whether psychological symptoms can be reversed when CP and scratch lesions improve is an issue that needs further exploration.

Facing the challenges of chronic pruritus: a report from a multi-disciplinary medical itch centre in Germany

The complex nature and difficult-to-establish aetiology of chronic pruritus (CP) makes it challenging to provide medical care for patients with CP. This challenge can only be met with a multidisciplinary approach. The first multidisciplinary Itch Centre in Germany was established at the University of Münster in 2002 to meet the needs of this patient population. More than 2,500 outpatients and 400 inpatients are diagnosed and receive treatment each year. To ensure evidence-based medical care, an electronic system for medical documentation and patient-reported outcomes was established. Automated data transfer to a research database enables comprehensive data analysis. Our translational research has characterized peripheral and central itch mechanisms, provided novel clustering of CP patients, and identified novel target-specific therapies (e.g. neurokinin 1 receptor-antagonist). The multidisciplinary approach, combined with basic, clinical and translational research, enables comprehensive medical care of patients as well as implementation of high-quality experimental and clinical studies.

Dimensions of the operationalized psychodynamic diagnosis system that predict long-term outcome after inpatient psychotherapy

BACKGROUND/AIMS

To determine whether the Operationalized Psychodynamic Diagnosis (OPD) system can be useful in predicting patient outcome in the long term.

METHODS

OPD was assessed by the therapists prior to and after inpatient treatment. Patients completed psychometric scales at the start and completion of psychosomatic-psychotherapeutic inpatient treatment and at the follow-up. Outcome was defined by the general factor emerging from a principal component analysis of the Brief Symptom Inventory, Hospital Anxiety and Depression Scale and Inventory of Interpersonal Problems at katamnesis, representing individual differences in general distress.

RESULTS

Several dimensions of the OPD system proved to be predictors of general distress at the follow-up in 253 former inpatients. Negative predictors of long-term outcome were the high internal impediments to change, namely high secondary gains from illness and also less integrated structural abilities. Positive OPD predictors of long-term outcome were the treatment success achieved at the end of inpatient psychotherapy in changing the illness concept towards a psychological understanding of symptoms, lower levels of complaints and a higher functional level. Also the achieved level of awareness for the individual maladaptive behavioral pattern is predictive of a favorable long-term outcome.

CONCLUSIONS

The results provide evidence for the clinical relevance and the predictive value of OPD. © 2014 S. Karger AG, Basel.

Diagnostic classification based on functional connectivity in chronic pain: model optimization in fibromyalgia and rheumatoid arthritis

RATIONALE AND OBJECTIVES

The combination of functional magnetic resonance imaging (fMRI) of the brain with multivariate pattern analysis (MVPA) has been proposed as a possible diagnostic tool. Goal of this investigation was to identify potential functional connectivity (FC) differences in the salience network (SN) and default mode network (DMN) between fibromyalgia syndrome (FMS), rheumatoid arthritis (RA), and controls (HC) and to evaluate the diagnostic applicability of derived pattern classification approaches.

MATERIALS AND METHODS

The resting period during an fMRI examination was retrospectively analyzed in women with FMS (n = 17), RA (n = 16), and HC (n = 17). FC was calculated for SN and DMN subregions. Classification accuracies of discriminative MVPA models were evaluated with cross-validation: (1) inferential test of a single method, (2) explorative model optimization.

RESULTS

No inferentially tested model was able to classify subjects with statistically significant accuracy. However, the diagnostic ability for the differential diagnostic problem exhibited a trend to significance (accuracy: 69.7%, P = .086). Optimized models in the explorative analysis reached accuracies up to 73.5% (FMS vs. HC), 78.8% (RA vs. HC), and 78.8% (FMS vs. RA) whereas other models performed at or below chance level. Comparable support vector machine approaches performed above average for all three problems.

CONCLUSIONS

Observed accuracies are not sufficient to reliably differentiate between FMS and RA for diagnostic purposes. However, some indirect evidence in support of the feasibility of this approach is provided. This exploratory analysis constitutes a fundamental model optimization effort to be based on in further investigations.

Assessment of personality functioning: validity of the operationalized psychodynamic diagnosis axis IV (structure)

BACKGROUND

The assessment of personality functioning has recently become a focus of psychiatric diagnostics. The interview-based Operationalized Psychodynamic Diagnosis (OPD-2) provides a 'structure axis' for the assessment of personality functioning.

METHODS

One hundred twenty-four psychiatric patients were diagnosed by means of the Structured Clinical Interviews for DSM-IV (SCID-I and SCID-II), underwent OPD-2 interviews, and completed 9 questionnaires.

RESULTS

The OPD-2 structure axis shows good interrater reliability (intraclass correlation = 0.793). Correlations between the OPD-2 structure axis domains and a priori selected questionnaire scales were of medium size and significant. Patients with a personality disorder (PD) showed significantly worse personality functioning than those without. In cluster B PD, personality functioning was more severely impaired than in cluster C PD.

DISCUSSION

The OPD-2 structure axis shows good reliability as well as concurrent and discriminant validity and can be recommended for clinical use and research purposes.

[The significance of the principal diagnosis in Germany's new payment system for inpatient treatment of mental disorders]

In 2013 Germany implemented a new payment system for the inpatient treatment of mental disorders. Besides perpetuating a per-diem payment, the payment system sets up a classification system that groups cases with comparable costs per diem. The first release of the system reveals the principal diagnosis to be the main grouping variable. Especially in psychosomatic and psychotherapy this approach seems to be at least questionable. Because of the insufficiently precise definition of the assignment of the principal diagnosis in the coding standards - and therefore the expected conflicts between clinics and health insurance funds - this paper discusses the difficulties involved in defining the principal diagnosis. It also formulates recommendations of how the principal diagnosis should be assigned.

Sex differences in itch perception and modulation by distraction--an FMRI pilot study in healthy volunteers

BACKGROUND

Even though itch is a common syndrome of many diseases there is only little knowledge about sex and gender differences in pruritus, especially in central itch perception and modulation. To our knowledge, this is the first fMRI study examining sex differences in perception and its modulation by distraction.

METHODS

Experimental itch was induced by application of histamine (0.1 mM) via microdialysis fibers twice at the left forearm and twice at the left lower leg in 33 healthy volunteers (17 females, 16 males). The brain activation patterns were assessed by fMRI during itch without and with distraction (Stroop task). Between the various conditions, subjects were asked to rate itch intensity, desire to scratch and pain intensity. In a second experiment in 10 of the 33 volunteers histamine was replaced by saline solution to serve as control for the 'Stroop' condition.

RESULTS

Women generally presented higher itch intensities compared to men during itch over the course of the experiment. A more specific analysis revealed higher itch intensities and desire to scratch in women during experimental induced itch that can be reduced by distraction at the lower legs when itch is followed by 'Stroop'. In contrast, men depicted significant reduction of 'itch' by 'Stroop' at the forearms. Women depicted higher brain activation of structures responsible for integration of sensory, affective information and motor integration/planning during 'itch' and 'Stroop' condition when compared to men. No sex differences were seen in the saline control condition.

CONCLUSION

Women and men exhibited localisation dependent differences in their itch perception with women presenting higher itch intensities and desire to scratch. Our findings parallel clinical observations of women reporting higher itch intensities depending on itch localisation and suffering more from itch as compared to men.

Reliability and validity of the German version of the Structured Interview of Personality Organization (STIPO)

BACKGROUND

The assessment of personality organization and its observable behavioral manifestations, i.e. personality functioning, has a long tradition in psychodynamic psychiatry. Recently, the DSM-5 Levels of Personality Functioning Scale has moved it into the focus of psychiatric diagnostics. Based on Kernberg's concept of personality organization the Structured Interview of Personality Organization (STIPO) was developed for diagnosing personality functioning. The STIPO covers seven dimensions: (1) identity, (2) object relations, (3) primitive defenses, (4) coping/rigidity, (5) aggression, (6) moral values, and (7) reality testing and perceptual distortions. The English version of the STIPO has previously revealed satisfying psychometric properties.

METHODS

Validity and reliability of the German version of the 100-item instrument have been evaluated in 122 psychiatric patients. All patients were diagnosed according to the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) and were assessed by means of the STIPO. Moreover, all patients completed eight questionnaires that served as criteria for external validity of the STIPO.

RESULTS

Interrater reliability varied between intraclass correlations of .89 and 1.0, Crohnbach's α for the seven dimensions was .69 to .93. All a priori selected questionnaire scales correlated significantly with the corresponding STIPO dimensions. Patients with personality disorder (PD) revealed significantly higher STIPO scores (i.e. worse personality functioning) than patients without PD; patients cluster B PD showed significantly higher STIPO scores than patients with cluster C PD.

CONCLUSIONS

Interrater reliability, Crohnbach's α, concurrent validity, and differential validity of the STIPO are satisfying. The STIPO represents an appropriate instrument for the assessment of personality functioning in clinical and research settings.

Prediction of PTSD in Police Officers after Six Months – a Prospective Study

The aim of this prospective study was to explore the predictors for the development of PTSD in police officers six months after encountering situations of a potentially traumatic nature. Fifty-nine police officers were studied immediately after the event (T1) and six months later (T2). At T2 PTSD was assessed using the Structured Clinical Interview for DSM-IV (SCID-I). PTSD was predicted by intrusions (Impact of Event Scale–Revised; IES-R), the impairment scale (is), global assessment of functioning scale (GAF), gender, age and sense of coherence scale (SOC). The diagnosis of an acute stress disorder (ASD) at T1 had a high specificity for identifying PTSD at T2. The strongest predictor for the development of PTSD was found to be the factor intrusions. Contrary to our expectations, age was not a significant predictive factor for PTSD. Thus, acute stress disorder (ASD) and a high degree of intrusions experienced immediately after a traumatic incident helped to identify early police officers at risk of developing chronic PTSD.

[A longitudinal analysis of the inpatient treatment of the elderly in psychosomatic departments]

OBJECTIVES

This article investigates the development of the inpatient treatment capabilities of older patients from the age of 50 onward in inpatient psychosomatic-psychotherapeutic departments over a period of 15 years.

METHOD

A Germany-wide postal survey that was almost identical to two previously conducted cross-sectional surveys (Lange et al. 1995; Wenker 2010) was sent to psychosomatic-psychotherapeutic departments. This survey collected data on the status and concept of the department as well as on the number of patients, number of elderly people, programs for elderly people, and future concepts of the departments.

RESULTS

The response of psychosomatic departments was higher than in previous years. The forms of therapy used differ between the individual clinic subtypes. The programs for elderly people remained constant, as did the special qualification measures for employees. Proportionally more elderly patients from the age of 50 onward were treated in psychosomatic clinics and departments, two thirds of whom were women.

DISCUSSION

The survey revealed that psychosomatic-psychotherapeutic therapies for the treatment of elderly people increased over the last year. With regard to the demographic change and the future receptiveness of elderly people to psychotherapy, the inpatient sector seems to be prepared for the rising numbers of elderly people. How large the lack of therapy capacity needed for inpatient psychosomatic-psychotherapeutic treatment will be cannot be answered by this survey.

[The specific role of medical psychotherapy as seen by somatic physicians in general hospitals]

OBJECTIVES

We examined the attitude towards the importance of medical psychotherapy among physicians working in a hospital. We focused on their opinion about the general role of medical psychotherapy within the health care system as well as on their opinion about the importance of medical psychotherapy in different clinical situations.

METHOD

105 physicians with various clinical specialties were interviewed using a questionnaire designed for this purpose.

RESULTS

From the point of view of the interviewed physicians, medical psychotherapy plays an important role. Especially medical psychotherapists are considered to be competent in cases of life-threatening situations resulting from mental disorders (such as suicide, anorexia nervosa), in psychopharmacological treatment as well as in cases of medically unexplained physical symptoms. Furthermore, medical competence in psychotherapy is requested wherever there is close connection to physical illness (such as stressful events in medical contexts).

CONCLUSIONS

Especially in times of increasing specialization of physicians there is a need for medical psychotherapy in inpatient health care and clinical consultation.

[Evaluation of outpatient treatment units according to the Crime Victims' Regulation Act]

OBJECTIVE

Over the past years, 35 trauma outpatient units have been established in accordance with the Crime Victims' Compensation Act in the federal state of North Rhine-Westphalia (Germany) for both children and adolescents as well as for adults. They are operated by the social welfare authorities and, since 2008, by the regional authorities of Westphalia-Lippe and Rhineland. They enable victims to receive qualified psychotraumatological help within the first few days after suffering violence. Since trauma units have now been set up across most parts of this federal state, the time has come to assess the effectiveness of their acute care provision to victims of violence.

METHODS

In 2007, on the order of the Ministry of Labour, Health and Social Affairs of the federal state of North Rhine-Westphalia, trauma outpatient units were subjected to scientific evaluation. In 17 trauma outpatient units, a data assessment protocol was officially implemented that included repeat measurements (immediately before the initial contact, after completion of intervention, at follow-up six months after intervention) of traumatized subjects aged 14 and older. Socio-demographic data were gathered, and the scores of the Impact of Event Scale - Revised (IES-R), the Symptom Checkliste-27 (SCL-27), the simplified Beck Depressions Inventory (BDI-V), the Global Assessment of Functioning Scale (GAF) as well as the Cologne Risk Index (CRI) (expert rating) were collected.

RESULTS

Nearly three-fourths (65.9 %) of the traumatic experiences of the 211 patients investigated can be characterized as type-1 traumatisation. 31.8 % of patients were victims of crimes involving violations of the right to sexual self-determination (94.0 % of sexual offences being committed against girls and women). Crimes against physical integrity, which according to crime statistics are the most frequent of crimes against individuals (88.8 %, 34.8 % females), were suffered by 36.0 % of all patients of the trauma outpatient units (63.2 % being females). In 57.1 % of the victims, the interval between the traumatic event and initial intervention was less than a month. In 51.7 % (n = 109), suspicion of PTBS (F43.1) was raised at the initial presentation. The average of all instruments yielded an effect size of d = 1.04 (SD = 0.28) in a pre-post comparison. Pair-wise comparison showed highly significant differences in averages between pre and post (that is, between initial and follow-up measurements) in the sense of marked symptom reduction for all scales.

CONCLUSIONS

The services of the trauma outpatient units are utilized in a timely and targeted fashion. The calculated effects show that the trauma outpatient units offer highly effective services to crime victims seeking help there.

Sex hormone levels, genetic androgen receptor polymorphism, and anxiety in ≥50-year-old males

INTRODUCTION

While associations between somatic changes and sex hormone levels in aging men have been explored in many studies, the association of testosterone and estradiol with psychic symptoms other than depression and the role of the genetically determined CAG repeat (CAGn) polymorphism of the androgen receptor (AR) have received much less attention.

AIM

The purpose of this article is to investigate the associations between general anxiety, phobic anxiety and panic with sex hormone levels and the genetic androgen receptor polymorphism in aging males.

METHODS

This cross-sectional study of males aged ≥50 years included 120 consecutive patients of the Department of Psychosomatics and Psychotherapy, 76 consecutive patients of the Andrology Clinic, and 100 participants from the general population; all of them completed the Brief Symptom Inventory (BSI), the Aging Males' Symptoms (AMS) Scale, and the Patient Health Questionnaire (PHQ-9). Morning blood samples were analyzed for total and free testosterone, estradiol, sex hormone-binding globulin (SHBG), and the CAGn AR polymorphism. Psychosomatic patients also underwent psychiatric assessment.

MAIN OUTCOME MEASURES

Scores on the Anxiety subscales of the BSI and PHQ, Anxiety disorders according to International Classification of Diseases, 10th revision (ICD-10).

RESULTS

The two clinical samples had significantly longer CAGn of the AR and higher anxiety levels compared to the population sample. Anxiety scores were positively correlated with CAGn in psychosomatic patients and in andrological patients, in the latter also with estradiol levels, while the population sample showed no significant correlations between anxiety scores, CAGn and sex hormones. Anxiety cases according to BSI, PHQ, and ICD-10 had significantly longer CAGn of the AR when compared to the other participants, but there were no significant differences in testosterone or free testosterone levels.

CONCLUSIONS

Our results indicate that genetically determined long CAGn of the AR is an independent risk factor for higher anxiety, panic and phobic anxiety levels.

Aging males' symptoms in relation to the genetically determined androgen receptor CAG polymorphism, sex hormone levels and sample membership

Late-onset hypogonadism describes the co-occurrence of a range of physical, psychological and sexual symptoms in aging men, with the implication that these symptoms are caused by androgen deficiency. Previous investigations examined mostly population samples and did not take into account the testosterone modulating effects of the genetically determined CAG repeat polymorphism (CAGn) of the androgen receptor (AR) gene. This is the first study which investigates aging male symptoms (AMS) in relation to the genetically determined androgen receptor CAG polymorphism, estradiol and testosterone levels in men > or =50 years of age in a healthy population sample (n=100), outpatients of an andrological department (n=76) who presented with sexual and "aging male" symptoms and a psychosomatic/psychiatric sample (n=120) who presented with various psychological and medically unexplained somatic complaints. Although the population sample was significantly older than the two patient groups, they reported significantly fewer AMS and had higher testosterone levels and shorter CAG repeats of the AR. Regression analysis revealed influences of CAGn on the AMS global score and the psychological and somatic subscale only in the two patient samples, while testosterone had some impact on the sexual subscale. Our results suggest that the so-called aging male symptoms show a certain association to androgenicity, but that they are rather unspecific and of multifactorial origin. Other factors contributing to AMS need further clarification.

Is there any association between disturbed gastrointestinal visceromotor and sensory function and impaired quality of life in functional dyspepsia?

BACKGROUND Functional dyspepsia (FD) is now categorized into the epigastric pain syndrome (EPS) and the postprandial distress syndrome (PDS). However, the role of disturbed gastric emptying and sensory function for the reduction of health-related quality of life (HRQOL) has not yet been studied in EPS and PDS. METHODS A total of 300 refractory FD patients and 450 healthy blood donors (BD) were studied. BD were stratified in subjects with (BD+) and without (BD-) concomitant FD symptoms. Gastric motor and sensory function, generic and disease-specific HRQOL [physical (PCS) and mental component summary (MCS)] and affective disorders were assessed. Twenty randomly selected BD-, 50 BD+ (36 PDS, 72%), and 110 FD (95 PDS, 86.4%) patients had additional function testing. KEY RESULTS Health-related quality of life was significantly reduced in FD patients (PCS = 40.7 +/- 8.8, MCS = 39.7 +/- 11.3, both P < 0.0001) compared to BD+ (PCS = 52.0 +/- 7.6, MCS = 49.0 +/- 9.4) and BD- (PCS = 56.0 +/- 4.3, MCS = 52.8 +/- 7.2). GET (t((1/2)), min) was significantly (both P < 0.0001) longer in FD patients (143.0 +/- 7.3) compared to BD+ (101.1 +/- 6.3) and BD- (73.8 +/- 7.6). FD patients scored significantly higher for 'pain' (P < 0.0001) and 'nausea' (P = 0.023), there was no difference for 'fullness' compared to BD. Impairment of GET was not associated with HRQOL. In FD patients, an augmented symptom response to the test meal (fullness, nausea) was associated with MCS, there was no difference between FD patients with EPS or PDS. CONCLUSIONS & INFERENCES In EPS and PDS, delayed gastric empting and altered sensory function are disease markers but not directly linked to the severity of HRQOL impairment or clinical presentation of FD.

Fibromyalgia unique temporal brain activation during experimental pain: a controlled fMRI Study

Studies with functional neuroimaging support the hypothesis of central pain augmentation in fibromyalgia syndrome (FMS) with functional differences in areas of the medial pain system. To clarify whether these findings are unique to patients with FMS, BOLD-signal patterns during and before tonic experimental pain were compared to healthy controls and patients with rheumatoid arthritis (RA) as a chronic pain disorder of somatic origin. We expected different BOLD-signal patterns in areas of the medial pain system that were most pronounced in patients with FMS. An fMRI-block design before, during and after an incision was performed in patients with FMS (n = 17), RA (n = 16) and in healthy controls (n = 17). A 2-factorial model of BOLD-signal changes was designed to explore significant differences of brain activation between the groups during the pain stimulus. Additionally, the correlation of brain activity during the anticipation of pain with the amount of the impending pain was determined. We observed a FMS-unique temporal brain activation of the frontal cortex in patients with FMS. Moreover, areas of the motor cortex and the cingulate cortex presented a FMS-specific relation between brain activity during pain anticipation and the magnitude of the subsequent pain experience. Our results support the hypothesis that central mechanisms of pain processing in the frontal cortex and cingulate cortex may play an important role in patients with FMS.

Treatment of chronic pruritus with the selective serotonin re-uptake inhibitors paroxetine and fluvoxamine: results of an open-labelled, two-arm proof-of-concept study

Chronic pruritus is difficult to treat and requires the evaluation of new therapeutic modalities. We initiated an open-labelled, two-arm prospective, proof-of-concept study applying two selective serotonin re-uptake inhibitors on a long-term basis. Paroxetine and fluvoxamine were tested in a total of 72 pruritic patients (27 men, 45 women, age range 28-88 years, mean age 59.2 years). The reduction in pruritus was evaluated by analysis of visual analogue scores and determination of the maximal antipruritic effect (maximal percentual reduction in pruritus). Forty-nine of 72 patients (68.0%) experienced a weak (n=9), good (n=16) or very good (n=24) antipruritic effect. Statistical analysis proved the efficacy of paroxetine and fluvoxamine with no significant difference. The best response was observed in patients with pruritus due to atopic dermatitis, systemic lymphoma and solid carcinoma. Chronic scratch lesions healed completely in 14/31 patients and partially in 17/31 patients. Adverse drug effects were observed in 70.8% of patients, resulting in discontinuation of treatment in 18 patients. These results support previous reports of high antipruritic potency of selective serotonin re-uptake inhibitors, which are a good alternative treatment modality in chronic pruritus. This should be confirmed in future double-blind studies.
