Police-referred psychiatric emergency presentations during the first and second wave of COVID-19 in Berlin, Germany: a retrospective chart review.

BACKGROUND: Literature on psychiatric emergency services (PES) presentations during the COVID-19 pandemic showed heterogeneous results regarding patients brought in by police (BIBP). This is the first study primarily focusing on patients BIBP in a PES during the COVID-19-period. METHODS: Case documentation records during the first and second wave of the COVID-19 pandemic in a PES in Berlin, Germany were analyzed using descriptive data analysis and binomial logistic regression analysis to detect factors that predict presentations BIBP. RESULTS: 5440 PES presentations: 20.4% BIBP during the first wave vs. 16.3% during its control period; second wave: 17.6% BIBP vs. 14.9% during its control period. In both waves, absolute increases in presentations BIBP were seen compared to control (p = .029, p = .028, respectively). COVID-19-period was a predictor for presentations BIBP during the first and the second wave. The following factors also predicted presentations BIBP: younger age, male gender, aggressive behavior, suicide attempt prior to presentation and diagnosis of psychotic or substance use disorders; depressive disorders were negatively associated. CONCLUSIONS: During the two first waves of the COVID-19 pandemic, there was an increase in presentations BIBP in a PES in Berlin. Regression analysis shows that the pandemic itself was a predictor of presentations BIBP. The underlying factors of this association need to be further elucidated in future research. Additionally, general factors predicting PES presentations BIBP are reported that replenish the present literature.

Environmental stress, minority status, and local poverty: risk factors for mental health in Berlin's inner city.

This study examines whether climate change-associated environmental stressors, including air and noise pollution, local heat levels, as well as a lack of surrounding greenspace, mediate the effects of local poverty on mental health, using the 28-item General Health Questionnaire. We recruited 478 adults who were representative of eleven of Berlin's inner-city neighborhoods. The relationship of individual-level variables, neighborhood-level sociodemographic and environmental data from the Berlin Senate (Department for Urban Development, Building and Housing) to mental health was assessed in a multilevel model using SPSS. We found that neither local exposure to environmental stressors, nor available greenspace as a protective factor, mediated the effects of local poverty on variance in mental health (all p values > 0.2). However, surrounding greenspace (r = -0.24, p < 0.001), nitrogen dioxide levels (r = 0.10, p < 0.05), noise pollution (rho = 0.15, p < 0.01), and particle pollution (r = 0.12, p < 0.001) were associated with local poverty, which, more strongly than individual factors, accounted for variance in mental health (ß = 0.47, p < 0.001). Our analysis indicates that the effects of local poverty on mental health are not mediated by environmental factors. Instead, local poverty was associated with both an increased mental health burden and the exposure to climate-related environmental stressors.

Suicidality in psychiatric emergency department situations during the first and the second wave of COVID-19 pandemic.

Psychiatric patients are prone to mental health deterioration during the Covid-19 pandemic. Little is known about suicidality in psychiatric patients during the Covid-19 pandemic. This study is a retrospective chart review of psychiatric emergency department (pED) presentations with present or absent suicidality (5634 pED attendances, 4110 patients) in an academic pED in Berlin, Germany. Poisson regression analysis was performed on the effect of Covid-19 period on suicidality (suicidal ideation (SI), suicide plans (SP) or suicide attempt (SA)) during the first (3/2/2020-5/24/2020 "first-wave") and second (9/15/2020-3/1/2021 "second-wave") wave of the Covid-19 pandemic compared to the same periods one year earlier. During the first-wave the number of pED visits per person with SI, SP and SA was higher compared to one year earlier (SI RR = 1.614; p = 0.016; SP RR = 2.900; p = 0.004; SA RR = 9.862; p = 0.003). SI and SP were predicted by interaction between substance use disorder (SUD) and second-wave (SI RR = 1.305, p = 0.043; SP RR = 1.645, p = 0.018), SA was predicted by interaction between borderline personality disorder (BPD) and second-wave (RR = 7.128; p = 0.012). Suicidality increased during the first-wave of Covid-19 pandemic in our sample. In the second-wave this was found in patients with SUD and BPD. These patients may be at particular risk of suicidality during the Covid-19 pandemic.

Racial discrimination and its impact on mental health.

There is evidence that racial discrimination at different levels has a major impact on mental health over the whole life span. It is related generally to poor health, with the relationship being particularly strong for mental health. All forms of structural, institutionalised, interpersonal and internalised racism as well as the cumulative impact of intersectional discrimination appear to be linked to mental health and well-being. Studies also show links between effects of racial discrimination and neurophysiology especially on the brain volume. All forms of racism need to be addressed in inter- and transdisciplinary ways in order to dismantle racial discrimination. This review provides an overview of these interconnections.

The dynamics of discrimination, resilience, and social support in the mental health of migrants with and without citizenship.

Perceived discrimination has a significant negative impact on indices of mental health. One potential buffering factor in this is psychological resilience, which encompasses the ability to recover from or adapt successfully to adversity and use coping strategies, such as positive reappraisal of adverse events. This study examines the role of resilience as well as social support in buffering these effects in groups of migrants both with and without local residence permits. We conducted a non-experimental observational study with a cross-sectional design, collecting a variety of health variables in migrant groups in a naturalistic setting, during the COVID-19 period. The total sample consisted of 201 subjects, 88 of whom had a German residence title and 113 did not. These two groups were compared on the following variables of interest: social support, resilience, discrimination, and general mental health. There was no evidence for a difference in mental health between migrants with and without citizenship. However, our results suggested that migrants without citizenship reported less social support, less resilience, and more discrimination, which continued to have a distinct effect on mental health beyond resilience and social support. Psychological resilience mediated the link between social support and mental health, as well as being related to the perception of discrimination in the migrant group without citizenship. In conclusion, our models of migrants with and without citizenship showed that resilience specifically directly affected perceived discrimination in those without citizenship. The high levels of discrimination and lack of social support, particularly in the migrant group without citizenship, are concerning and suggest a focus for future interventions.

Health promotion strategies toward improved healthcare access for migrants and refugees in Europe: MyHealth recommendations.

MyHealth European project (2017-2020) was committed to elaborate on models to engage vulnerable migrants and refugees (VMR) in their health through community involvement. Low healthcare access and poor quality of healthcare services for VMR is a common reality in many European countries. The purpose of the present study, as part of MyHealth project, was the development of an agenda for actions and consequent recommendations to tackle the issue. A qualitative research design was applied at four study sites in Barcelona, Spain; Berlin, Germany; Brno, Czech Republic and Athens, Greece. The Metaplan® group discussions allowed the collection, organization and process of ideas and opinions elaborated in the collaborative groups. In total, 14 sessions took place: 4 with health and social professionals (n = 41) and 10 with VMR (n = 77). A participatory thematic analysis was performed at every session and overall for all sessions a thematic analysis synthesized the findings. The suggested actions were divided into two levels of recommendations: (i) local authorities at destination country-related, such as the investment in health professionals' cultural competences, and (ii) VMR-related, such as adaptation of help-seeking behavior patterns. Special attention was proposed to women survivors of violence and homeless minors. The study concluded to an agenda for action in Europe. We advocate for a public health paradigm shift where, while holding a bottom-up approach, VMR as well as professionals working with them are actively and meaningfully engaged in the decision-making process of access-enhancing and health promotion strategies in a given socio-cultural context.

Low healthcare access and poor quality of healthcare services for vulnerable migrants and refugees (VMR) is a common reality in many European countries. As part of MyHealth project (2017­2020), a qualitative methodology was used to engage VMR and professionals in the decision-making of proposed actions and corresponding recommendations to address the issue.

[Utilization of a Specialized Outpatient Service for Parents with Mental Disorders]. / Inanspruchnahme einer Spezialsprechstunde für psychisch kranke Eltern.

BACKGROUND: Patients with mental disorders have a high need for support during the peripartum period. Only few outpatient services have specialized on parents with mental disorders. This study assesses a newly established outpatient unit. METHODS: We analyzed the population utilizing the outpatient service for parents with psychiatric disorders (N=279) at the psychiatric university hospital of Charité at St. Hedwig-hospital in Berlin, Germany, from June 2017 until December 2021. RESULTS: The service was mainly utilized by individuals with affective disorders, a higher education and good compliance. Patients with migration background started psychotherapy less often. DISCUSSION: The data indicate a good acceptance of a specialized outpatient unit for parents with psychiatric disorders; however, it was mainly utilized by individuals with a higher socioeconomic status and less commonly by individuals with severe mental illness. More specialized treatment units for parents would be desirable.

Offspring's risk for suicidal behaviour in relation to parental death by suicide: systematic review and meta-analysis and a model for familial transmission of suicide.

BACKGROUND: Exposure to parental suicide has been associated with increased risk for suicide and suicide attempts, although the strength of this association is unclear as evidence remains inconsistent. AIMS: To quantify this risk using meta-analysis and identify potential effect modifiers. METHOD: A systematic search in PubMed, PsycInfo and Embase databases to 2020 netted 3614 articles. Inclusion criteria were: observation of history of parental death by suicide, comparison with non-exposed populations and definition of suicide and suicide attempt according to standardised criteria. We focused on population-based studies. The primary outcome was the pooled relative risk (RR) for incidence of suicide attempt and suicide in offspring of a parent who died by suicide compared with offspring of two living parents. Additionally, we compared the RR for attempted and completed suicide after parental suicide with the RR for attempted and completed suicide after parental death by other causes. RESULTS: Twenty studies met our inclusion criteria. Offspring exposed to parental suicide were more likely to die by suicide (RR = 2.97, 95% CI 2.50-3.53) and attempt suicide (RR = 1.76, 95% CI 1.58-1.96) than offspring of two living parents. Furthermore, their risk of dying by or attempting suicide was significantly higher compared with offspring bereaved by other causes of death. CONCLUSIONS: The experience of losing a parent to suicide is a strong and independent risk factor for suicidal behaviour in offspring. Our findings highlight the need for prevention strategies, outreach programmes and support interventions that target suicide-related outcomes in the exposed population.

Observed and personally experienced discrimination: findings of a cross-sectional survey of physicians and nursing staff.

BACKGROUND: Discrimination against hospital staff based on ascribed features is prevalent in healthcare systems worldwide. Detrimental effects on health and quality of patient care have been shown. Our study aims to describe and analyse the discrimination experiences of both physicians and nurses, specifically for the German hospital context. METHODS: A cross-sectional online survey on observed and personally experienced discrimination at work addressed staff from 22 hospitals of two organizations in Germany. Sociodemographic and occupational as well as institutional characteristics served as independent variables. In multivariable analyses, block- and stepwise logistic regressions were calculated for the two dependent variables (witness and victim of discrimination). Sensitivity analyses with imputed data for missings were performed. RESULTS: N = 800 healthcare professionals (n = 243 physicians, n = 557 nurses; response rate: 5.9%) participated in the survey. 305 respondents (38.1%) were witnesses of discrimination, while 108 respondents (13.5%) were victims of discrimination in their wards. Reasons for observed discriminatory acts were predominantly attributed to the ethnicity of the person concerned, their appearance and language, whereas personally affected staff most frequently cited gender as a reason, followed by ethnicity, and physical appearance. In multivariable models, cultural competence significantly increased the likelihood of witnessing discrimination (ß = .575; p = .037). In terms of the likelihood of being a victim of discrimination, in addition to cultural competence (ß = 2.838; p = < .001), the interaction of the effects of gender and professional group was statistically significant (ß = .280; p = .010). CONCLUSIONS: Given the extent of experienced and observed discrimination, appropriate institutional responses are needed. Further research on discriminatory structures in the German-speaking health care system should focus on discrimination at the intersection of ethnicity, gender and occupation.

Organisational and staff-related effects on cultural competence in the hospital setting: a cross-sectional online survey of nursing and medical staff.

BACKGROUND: Cultural competence is considered a core qualification for dealing with socio-cultural diversity and balancing disparities in health care. OBJECTIVES: To explore features supporting and inhibiting cultural competence in the hospital at both organisational and staff levels. DESIGN: Cross-sectional online survey in the form of a full census from May to November 2018. SETTING: Two organisations that run a total of 22 hospitals in Germany. PARTICIPANTS: Eight hundred nursing and medical professionals [nurses: n = 557; doctors: n = 243]. METHODS: Using the Short Form Cultural Intelligence SCALE (SFCQ), cultural competence was measured and its relation to potential influencing factors at staff level and organisational level examined, using bivariate (t-Test, one-way ANOVA, Pearson and Spearman correlations) and multivariate (multiple linear regression) approaches. Model 1 examined features at organisational level, Model 2 at individual level and Model 3 included organisational and individual features. RESULTS: The mean cultural competence measured was 3.49 [min.: 1.3; max.: 5.0]. In the bivariate and isolated multivariate models [Models 1 and 2], factors on both organisational and individual levels were significantly related to the hospital staff's cultural competence. The multivariate overview [Model 3], however, revealed that individual features at staff level were the statistically relevant predictors. Positive influencing features included staff's assessment of the importance of cultural competence in their professional context [B: 0.368, 95% confidence interval 0.307; 0.429], participation in competence training [B: 0.193; 95% confidence interval 0.112; 0.276] and having a migration background [B: 0.175; 95% confidence interval 0.074; 0.278], while negative features included length of medical service [B: -0.004; 95% confidence interval -0.007; -0.001]. CONCLUSIONS: The development and practice of cultural competence appear to be determined less by organisational features and more on the level of individual actors. In addition to staff development, adequate organisational structures and an economic incentive system are required to promote sociocultural diversity in hospitals.

Quality of life, depression, and anxiety of patients undergoing hemodialysis: Significant role of acceptance of the illness.

OBJECTIVE: Routine dialysis is stressful. It has the possibility of leading to depression and anxiety and also reducing patients' quality of life. Despite these significant consequences, these comorbidities have been rarely studied among Indonesian patients. This study aims to examine the rate of depression, anxiety, and the role of acceptance of their illness on patients' quality of life. METHOD: A total of 213 patients undergoing hemodialysis in three general hospitals in Aceh, Indonesia, were included in the study. The presence of depression, anxiety, and the quality of life of each patient was assessed using the hospital anxiety and depression scale and WHO quality of life-BREF questionnaires. RESULTS: The prevalence of depression and anxiety was 46% and 30.5%, respectively. Depression was only associated with the presence of anxiety and the duration of hemodialysis. Anxiety was negatively associated with quality of life but positively associated with depression and the prescription of an anxiolytic. Overall quality of life was associated with age, body mass index, the presence of anxiety, and acceptance of the illness. Acceptance of the illness was also independently associated with almost every domain of patients' quality of life. CONCLUSIONS: The rates of depression and anxiety among patients undergoing hemodialysis in the current study setting are relatively similar to the rates in other settings. Patients' acceptance of their illnesses is significantly associated with the occurrence of anxiety and quality of life. Therefore, health practitioners should help patients accept their illnesses and the administration of regular hemodialysis.

[Psychological stress during the COVID-19 pandemic: consequences for psychiatric patients and therapeutic implications]. / Psychische Belastung während der COVID-19-Pandemie: Konsequenzen für psychiatrisch Erkrankte und therapeutische Implikationen.

BACKGROUND: The outbreak of the COVID-19 disease and the rapid spread of the inducing coronavirus SARS-CoV­2 threatens not only people's physical health but also their mental health. Its influence on incidence and course of existing illnesses in the psychiatric outpatient sector in Germany is still unknown. METHODS: The medical reports of 682 persons in psychiatric treatment were retrospectively investigated, regarding their subjective response to this pandemic and its clinical relevance. RESULTS: Of the patients 60.5% (n = 378) experienced greater psychological stress, 14.5% (n = 99) reported fear of the SARS-CoV­2 and the possible danger of infection, 25.5% (n = 174) reported fear resulting from the protective measures taken (lock down) and 4.3% (n = 29) reported fear of both. This differed significantly across diagnoses: people with anxiety disorders reported significantly greater stress as well as greater fear of the virus, whereas people with psychoses were significantly less affected than the other patients. Of the participants 43.7% (n = 132) were so strongly affected that acute treatment had to be implemented and 6.0% (n = 18) had to be referred to inpatient care. DISCUSSION: People with mental illnesses are particularly vulnerable to the psychological strain of the COVID-19 pandemic. Long-term studies on the further course of disease will be necessary. Additional studies that test interventions to build resilience in this population will also be needed.

[Debts, loans and unpaid bills among day patients and inpatients in psychiatric care in Berlin, Germany]. / Schulden, Kredite und unbezahlte Rechnungen unter Nutzer*Innen teilstationärer und stationärer psychiatrischer Behandlung in Berlin.

BACKGROUND: Previous studies among the general population indicated an association between mental illnesses and different forms of financial difficulties, such as indebtedness. OBJECTIVE: Investigation of the financial burden and associated factors among inpatients and day clinic patients in psychiatric care. MATERIAL AND METHODS: A total of 488 patients in psychiatric care in the catchment area of the Psychiatric University Hospital Charité at St. Hedwig Hospital participated in a cross-sectional patient survey carried out with a structured interview regarding financial burden, sociodemographic and clinical variables. RESULTS: Of the participants 269 (55.1%) showed outstanding debts, loans or unpaid bills. Among the participants who were willing to give information about the amount of debts, the majority (47.0%) had debts between 1000 € and 9999 € and 36.3% between 10,000 € and 99,999 €. In the binary regression models, younger age and substance use disorders were factors significantly associated with outstanding debts. Of the participants 22.3% had outstanding debts >10,000 € and were depending on social welfare, so that indebtedness could be assumed. CONCLUSION: Financial burdens and outstanding debts among patients in psychiatric care should be inquired about and considered more intensively in practice. Suitable models of support need to be developed and evaluated.

Attitudes towards psychopharmacology and psychotherapy in psychiatric patients with and without migration background.

BACKGROUND: Sociodemographic factors, attitude towards treatment and acculturation may be important factors influencing the decision of immigrants to seek and maintain psychiatric treatment. A better understanding of these factors may significantly improve treatment adherence and outcome in these patients. Therefore, we investigated factors associated the attitude towards psychotherapy and medication in a sample of psychiatric outpatients with and without migration background. METHODS: N = 381 patients in a psychiatric outpatient unit offering specialized treatment for migrants were included in this study. Attitude towards psychotherapy was assessed using the Questionnaire on Attitudes Toward Psychotherapeutic Treatment, attitude towards medication with the Drug Attitude Inventory-10. Acculturation, symptom load and sociodemographic variables were assessed in a general questionnaire. Statistical analyses included analyses of covariance and hierarchical regression. RESULTS: Patients of Turkish and Eastern European origin reported a significantly more positive attitude towards medication than patients without migration background. When controlling for sociodemographic and clinical variables, we did not observe any significant differences in attitude towards psychotherapy. Acculturation neither influenced the attitude towards psychotherapy nor towards medication. CONCLUSION: Our study indicates that sociodemographic and clinical factors may be more relevant for patients´ attitudes towards treatment than acculturation. Considering these factors in psychiatric treatment of patients with migration background may improve treatment outcome and adherence.

[Mental Disorders among Refugees]. / Psychische Störungen bei MigrantInnen.

Mental Disorders among Refugees Abstract. Children and adolescents with migration and refugee backgrounds are subject to various health-related, psychosocial, sociocultural, and economic burdens that may influence the prevalence, manifestation, course, and treatment as well as prognosis of mental disorders. In addition, they are particularly disadvantaged by numerous barriers to accessing the mental healthcare and treatment granted natives. The so-called transition gap only exacerbates the situation. As a solution, we provide recommendations for improving the mental healthcare of children and adolescents with a migration and refugee background analogous to the situation for adults. For inpatient settings, where mental healthcare is inadequate, we recommend the establishment of so-called adolescent wards under child and adolescent and adult psychiatric-psychotherapeutic management, with appropriate nursing and therapeutic staffing as well as a special "transition management" including the training of intercultural competence.

Prevalence of prolonged grief disorder in a sample of female refugees.

BACKGROUND: Prolonged Grief Disorder (PGD) is a distinct syndrome that follows bereavement. It is different from other mental disorders and is characterized by symptoms such as yearning for the bereaved, or intense emotional pain or distress. Violent loss is one major risk factor for the development of PGD. OBJECTIVES: PGD has been studied in different populations, mostly in small samples, with only a few of them being representative. Although research highlighted that traumatic experiences paired with challenges related to migration make refugees particularly vulnerable to PGD, PGD has only rarely been studied in refugees. Thus, this article a) examines the prevalence of PGD in female refugees in Germany according to the criteria proposed by Prigerson and colleagues in 2009, and b) associates PGD with other common psychopathology (e.g. anxiety, depression, somatization and trauma). METHOD: A total of 106 female refugees were assessed for bereavement and PGD. Of these 106 individuals, 85 were interviewed using the Prolonged Grief Disorder Scale (PG-13). Symptoms of anxiety and depression were assessed by the Hopkins Symptom Checklist-25 (HSCL-25), somatization was assessed by the Somatization Subscale of the Symptom-Checklist-90 (SCL-90), and the number of witnessed and experienced trauma was assessed by the Posttraumatic Diagnostic Scale (PDS/HTQ). RESULTS: Ninety of the 106 participants had experienced bereavement, and among those, 9.41% met criteria for PGD. The most frequent PGD symptoms were bitterness, longing or yearning for the bereaved, and lack of acceptance of the loss. Furthermore, grief symptoms were significantly associated with symptoms of depression, anxiety, somatization, and the number of experienced traumatic events. CONCLUSION: The PGD prevalence rate found corresponds with previous studies, demonstrating that prevalence rates for PGD are especially high in refugees. High prevalence rates of bereavement as well as PGD highlight the need for assessment and specifically tailored treatment of PGD in refugees. PGD goes along with significant psychopathology, which further emphasizes the need for treatment.

[Cultural Influence on Attitude towards Psychotherapy - A Comparison of Individuals of Turkish Origin with Individuals without Migration Background]. / Kulturabhängigkeit der Einstellung gegenüber psychotherapeutischer Behandlung bei Türkeistämmigen und Personen ohne Migrationshintergrund.

AIM: The present study compares the attitude towards psychotherapy of persons living in Germany with or without Turkish background. In this context, gender-related, disorder-specific and sociodemographic differences in openness towards psychotherapy are taken into account. METHODS: Individuals of Turkish origin (n=129) and individuals without migration background (n=129) were interviewed with the Questionnaire on Attitudes towards Psychotherapeutic Treatment, the Social Support Questionnaire, a short version of the Symptom-Checklist with the subscales anxiety, depression and somatization, and a sociodemographic questionnaire. RESULTS: The attitude towards psychotherapy is less positive in Turkish migrants than in people without migration background. Females, depressive individuals, persons with high social support, with children and a high level of education are more open towards psychotherapy. DISCUSSION: The attitude towards psychotherapy is influenced by gender, socio-demographic and disorder-specific factors and in particular by cultural factors. CONCLUSION: These results elucidate the need for better information about psychotherapy and the development of intercultural consulting services for migrants in Germany.

Weather conditions influence the number of psychiatric emergency room patients.

The specific impact of weather factors on psychiatric disorders has been investigated only in few studies with inconsistent results. We hypothesized that meteorological conditions influence the number of cases presenting in a psychiatric emergency room as a measure of mental health conditions. We analyzed the number of patients consulting the emergency room (ER) of a psychiatric hospital in Berlin, Germany, between January 1, 2008, and December 31, 2014. A total of N = 22,672 cases were treated in the ER over the study period. Meteorological data were obtained from a publicly available data base. Due to collinearity among the meteorological variables, we performed a principal component (PC) analysis. Association of PCs with the daily number of patients was analyzed with autoregressive integrated moving average model. Delayed effects were investigated using Granger causal modeling. Daily number of patients in the ER was significantly higher in spring and summer compared to fall and winter (p < 0.001). Three PCs explained 76.8% percent of the variance with PC1 loading mostly on temperature, PC2 on cloudiness and low pressure, and PC3 on windiness. PC1 and PC2 showed strong association with number of patients in the emergency room (p < 0.010) indicating higher patient numbers on warmer and on cloudy days. Further, PC1, PC2, and PC3 predicted the number of patients presenting in the emergency room for up to 7 days (p < 0.050). A secondary analysis revealed that the effect of temperature on number of patients was mostly due to lower patient numbers on cold days. Although replication of our findings is required, our results suggest that weather influences the number of psychiatric patients consulting the emergency room. In particular, our data indicate lower patient numbers during very cold temperatures.

[Simple guideline-oriented supportive tools in primary care: Effects on adherence to the S3/NV guideline unipolar depression]. / Niederschwellige leitlinienorientierte supportive Materialien (NILS) in der primärärztlichen Versorgung: Effekte auf die Orientierung an der S3/NV-Leitlinie Unipolare Depression.

Simple guideline-oriented supportive tools in primary care: Effects on adherence to the S3/NV guideline unipolar depression Objectives: Does the provision of supportive tools improve guideline-oriented recognition and treatment of patients with depression in primary care? METHODS: In a nested intervention study, as part of a larger epidemiological study program in German primary care, 46 randomly drawn practices received tools to facilitate identification and treatment decisions.Pre-post effects were compared to 42 matched control practices without intervention. RESULTS: The proportion of correctly identified depression cases was similar in the intervention (47.2%) and the control group (42.3%, p = 0.537). Compared to controls, practitioners in the intervention group rated their competence in case identification and treatment at post-intervention more positively (p = 0.016). No effects were observed regarding the usage of the tools, practitioners' attitudes towards national depression guidelines, and depression treatment procedures. CONCLUSIONS: Since provision of guideline-oriented tools did not improve recognition and quality of treatment, delineation of alternative strategies for enhanced guideline adherence in primary care for depression is warranted.
