Depression screening in patients with coronary heart disease : A narrative review of the current evidence.

In view of the large and sometimes conflicting body of research, this narrative review summarizes the current evidence on depression screening in patients with coronary heart disease. Depression is a risk factor for development and progression of coronary heart disease. Consequently, many international cardiac guidelines recommend screening for depression in patients with coronary heart disease. However, the efficacy and implementation of these guidelines are debated due to the lack of empirical evidence supporting the benefits of routine depression screening. Studies conducted in cardiac routine care support this assumption: Patients with positive depression screens do not receive adequate follow-up care, which highlights gaps in the detection-to-treatment pathway. Barriers to effective screening and treatment include system-level factors, such as insufficient integration of mental health resources in cardiology, and patient-related factors like stigma and low acceptance of mental health treatment. Innovative interventions that address these barriers and involve patients as active partners in depression care should be developed through a theory-driven, transparent, multistage process involving key stakeholders such as patients, nurses, and cardiologists. A sound methodological evaluation of such multilevel interventions could answer the question of whether early detection of depression in patients with coronary heart disease would lead to health benefits.

Somatic symptom disorder symptoms in individuals at risk for heart failure: A cluster analysis with cross-sectional data from a population-based cohort study.

OBJECTIVE: Identifying whether experienced symptom burden in individuals with medical predisposition indicates somatic symptom disorder (SSD) is challenging, given the high overlap in the phenomenology of symptoms within this group. This study aimed to enhance understanding SSD in individuals at risk for heart failure. SUBJECTS AND METHODS: Cross-sectional data from the Hamburg City Health Study was analyzed including randomly selected individuals from the general population of Hamburg, Germany recruited from February 2016 to November 2018. SSD symptoms assessed with the Somatic Symptom Scale-8 and the Somatic Symptom Disorder-12 scale were categorized by applying cluster analysis including 412 individuals having at least 5% risk for heart failure-related hospitalization within the next ten years. Clusters were compared for biomedical and psychological factors using ANOVA and chi-square tests. Linear regressions, adjusting for sociodemographic, biomedical, and psychological factors, explored associations between clusters with general practitioner visits and quality of life. RESULTS: Three clusters emerged: none (n = 215; 43% female), moderate (n = 151; 48% female), and severe (n = 46; 54% female) SSD symptom burden. The SSS-8 mean sum scores were 3.4 (SD = 2.7) for no, 6.4 (SD = 3.4) for moderate, and 12.4 (SD = 3.7) for severe SSD symptom burden. The SSD-12 mean sum scores were 3.1 (SD = 2.6) for no, 12.2 (SD = 4.2) for moderate, and 23.5 (SD = 6.7) for severe SSD symptom burden. Higher SSD symptom burden correlated with biomedical factors (having diabetes: p = .005 and dyspnea: p ≤ .001) and increased psychological burden (depression severity: p ≤ .001; anxiety severity: p ≤ .001), irrespective of heart failure risk (p = .202). Increased SSD symptoms were associated with more general practitioner visits (ß = 0.172; p = .002) and decreased physical quality of life (ß = -0.417; p ≤ .001). CONCLUSION: Biomedical factors appear relevant in characterizing individuals at risk for heart failure, while psychological factors affect SSD symptom experience. Understanding SSD symptom diversity and addressing subgroup needs could prove beneficial.

The efficacy of automated feedback after internet-based depression screening (DISCOVER): an observer-masked, three-armed, randomised controlled trial in Germany.

BACKGROUND: Despite the availability of effective treatments, most depressive disorders remain undetected and untreated. Internet-based depression screening combined with automated feedback of screening results could reach people with depression and lead to evidence-based care. We aimed to test the efficacy of two versions of automated feedback after internet-based screening on depression severity compared with no feedback. METHODS: DISCOVER was an observer-masked, three-armed, randomised controlled trial in Germany. We recruited individuals (aged ≥18 years) who were undiagnosed with depression and screened positive for depression on an internet-based self-report depression rating scale (Patient Health Questionnaire-9 [PHQ-9] ≥10 points). Participants were randomly assigned 1:1:1 to automatically receive no feedback, non-tailored feedback, or tailored feedback on the depression screening result. Randomisation was stratified by depression severity (moderate: PHQ-9 score 10-14 points; severe: PHQ-9 score ≥15 points). Participants could not be masked but were kept unaware of trial hypotheses to minimise expectancy bias. The non-tailored feedback included the depression screening result, a recommendation to seek professional diagnostic advice, and brief general information about depression and its treatment. The tailored feedback included the same basic information but individually framed according to the participants' symptom profiles, treatment preferences, causal symptom attributions, health insurance, and local residence. Research staff were masked to group allocation and outcome assessment as these were done using online questionnaires. The primary outcome was change in depression severity, defined as change in PHQ-9 score 6 months after random assignment. Analyses were conducted following the intention-to-treat principle for participants with at least one follow-up visit. This trial was registered at ClinicalTrials.gov, NCT04633096. FINDINGS: Between Jan 12, 2021, and Jan 31, 2022, 4878 individuals completed the internet-based screening. Of these, 1178 (24%) screened positive for depression (mean age 37·1 [SD 14·2] years; 824 [70%] woman, 344 [29%] men, and 10 [1%] other gender identity). 6 months after random assignment, depression severity decreased by 3·4 PHQ-9 points in the no feedback group (95% CI 2·9-4·0; within-group d 0·67; 325 participants), by 3·5 points in the non-tailored feedback group (3·0-4·0; within-group d 0·74; 319 participants), and by 3·7 points in the tailored feedback group (3·2-4·3; within-group d 0·71; 321 participants), with no significant differences among the three groups (p=0·72). The number of participants seeking help for depression or initiating psychotherapy or antidepressant treatment did not differ among study groups. The results remained consistent when adjusted for fulfilling the DSM-5-based criteria for major depressive disorder or subjective belief of having a depressive disorder. Negative effects were reported by less than 1% of the total sample 6 months after random assignment. INTERPRETATION: Automated feedback following internet-based depression screening did not reduce depression severity or prompt sufficient depression care in individuals previously undiagnosed with but affected by depression.

Clinical effectiveness of patient-targeted feedback following depression screening in general practice (GET.FEEDBACK.GP): an investigator-initiated, prospective, multicentre, three-arm, observer-blinded, randomised controlled trial in Germany.

BACKGROUND: Screening for depression in primary care alone is not sufficient to improve clinical outcomes. However, targeted feedback of the screening results to patients might result in beneficial effects. The GET.FEEDBACK.GP trial investigated whether targeted feedback of the depression screening result to patients, in addition to feedback to general practitioners (GPs), leads to greater reductions in depression severity than GP feedback alone or no feedback. METHODS: The GET.FEEDBACK.GP trial was an investigator-initiated, multicentre, three-arm, observer-blinded, randomised controlled trial. Depression screening was conducted electronically using the Patient Health Questionnaire-9 (PHQ-9) in 64 GP practices across five regions in Germany while patients were waiting to see their GP. Currently undiagnosed patients (aged ≥18 years) who screened positive for depression (PHQ-9 score ≥10), were proficient in the German language, and had a personal consultation with a GP were randomly assigned (1:1:1) into a group that received no feedback on their depression screening result, a group in which only the GP received feedback, or a group in which both GP and patient received feedback. Randomisation was stratified by treating GP and PHQ-9 depression severity. Trial staff were masked to patient enrolment and study group allocation and GPs were masked to the feedback recieved by the patient. Written feedback, including the screening result and information on depression, was provided to the relevant groups before the consultation. The primary outcome was PHQ-9-measured depression severity at 6 months after randomisation. An intention-to-treat analysis was conducted for patients who had at least one follow-up visit. This study is registered at ClinicalTrials.gov (NCT03988985) and is complete. FINDINGS: Between July 17, 2019, and Jan 31, 2022, 25 279 patients were approached for eligibility screening, 17 150 were excluded, and 8129 patients completed screening, of whom 1030 (12·7%) screened positive for depression. 344 patients were randomly assigned to receive no feedback, 344 were assigned to receive GP-targeted feedback, and 339 were assigned to receive GP-targeted plus patient-targeted feedback. 252 (73%) patients in the no feedback group, 252 (73%) in the GP-targeted feedback group, and 256 (76%) in the GP-targeted and patient-targeted feedback group were included in the analysis of the primary outcome at 6 months, which reflected a follow-up rate of 74%. Gender was reported as female by 637 (62·1%) of 1025 participants, male by 384 (37·5%), and diverse by four (0·4%). 169 (16%) of 1026 patients with available migration data had a migration background. Mean age was 39·5 years (SD 15·2). PHQ-9 scores improved for each group between baseline and 6 months by -4·15 (95% CI -4·99 to -3·30) in the no feedback group, -4·19 (-5·04 to -3·33) in the GP feedback group, and -4·91 (-5·76 to -4·07) in the GP plus patient feedback group, with no significant difference between the three groups (global p=0·13). The difference in PHQ-9 scores when comparing the GP plus patient feedback group with the no feedback group was -0·77 (-1·60 to 0·07, d=-0·16) and when comparing with the GP-only feedback group was -0·73 (-1·56 to 0·11, d=-0·15). No increase in suicidality was observed as an adverse event in either group. INTERPRETATION: Providing targeted feedback to patients and GPs after depression screening does not significantly reduce depression severity compared with GP feedback alone or no feedback. Further research is required to investigate the potential specific effectiveness of depression screening with systematic feedback for selected subgroups. FUNDING: German Innovation Fund.

Patient-centered evaluation of an expectation-focused intervention for patients undergoing heart valve surgery: a qualitative study.

Objective: Randomized controlled trials demonstrate the effectiveness of expectation-focused interventions in improving recovery outcomes following cardiac surgery. For dissemination in routine health care, it is important to capture the perspective of affected individuals. This qualitative study explores the perceived benefits and intervention-specific needs of patients who received expectation-focused intervention in the context of heart valve surgery. In addition, it explores potential barriers and adverse effects. Methods: As part of an Enhanced Recovery After Surgery (ERAS) program within a multicentered randomized controlled trial, patients undergoing minimally invasive heart valve surgery received an intervention focused on their expectations. Six weeks after the intervention, semi-structured interviews were conducted with 18 patients to assess its feasibility, acceptance, barriers, benefits, and side effects. The transcribed interviews were analyzed using qualitative content analysis. Results: The results indicate that both the intervention and the role of the patient and psychologist are key aspects in evaluating the expectation-focused intervention. Five key themes emerged from the patients' perspective: personal needs, expectations and emotions, relationship, communication, and individuality. Patients valued the preparation for surgery and recovery and the space for emotions. Establishing a trustful relationship and addressing stigmatization were identified as primary challenges within the intervention. Conclusion: Overall, patients experienced the expectation-focused intervention as helpful and no adverse effects were reported. Perceived benefits included enhanced personal control throughout the surgery and recovery, while the potential barrier of stigmatization towards a psychologist may complicate establishing a trustful relationship. Addressing personal needs, as a relevant topic to the patients, could be achieved through additional research to identify the specific needs of different patient subgroups. Enhancing the expectation-focused intervention could involve the implementation of a modular concept to address individual needs better.

Healthcare needs in elderly patients with chronic heart failure in view of a personalized blended collaborative care intervention: a cross sectional study.

Introduction: Few studies explored healthcare needs of elderly heart failure (HF) patients with comorbidities in view of a personalized intervention conducted by Care Managers (CM) in the framework of Blended Collaborative Care (BCC). The aims of the present study were to: (1) identify perceived healthcare needs/preferences in elderly patients with HF prior to a CM intervention; (2) investigate possible associations between healthcare needs/preferences, sociodemographic variables (age; sex) and number of comorbidities. Method: Patients aged 65 years or more affected by HF with at least 2 medical comorbidities were enrolled in the study. They were assessed by structured interviewing with colored cue cards that represented six main topics including education, individual tailoring of treatment, monitoring, support, coordination, and communication, related to healthcare needs and preferences. Results: Thirty-three patients (Italy = 21, Denmark = 7, Germany = 5; mean age = 75.2 ± 7.7 years; males 63.6%) were enrolled from June 2021 to February 2022. Major identified needs included: HF information (education), patients' involvement in treatment-related management (individual tailoring of treatment), regular checks of HF symptoms (monitoring), general practitioner update by a CM about progression of symptoms and health behaviors (coordination), and telephone contacts with the CM (communication). Regarding communication modalities with a CM, males preferred phone calls (χ2 = 6.291, p = 0.043) and mobile messaging services (χ2 = 9.647, p = 0.008), whereas females preferred in-person meetings and a patient dashboard. No differences in needs and preferences according to age and number of comorbidities were found. Discussion: The findings highlight specific healthcare needs and preferences in older HF multimorbid patients, allowing a more personalized intervention delivered by CM in the framework of BCC.

Public and patient involvement in the development of an internet-based guide for persistent somatic symptoms (GUIDE.PSS): A qualitative study on the needs of those affected.

BACKGROUND: Persistent somatic symptoms (PSS) frequently remain under-treated in health care settings. Evidence-based services that lead affected individuals to early guideline-based care are currently missing. This study aimed to identify the needs of those affected concerning an internet-based guide. The second aim was to evaluate public and patient involvement (PPI). METHODS: Participants experiencing PSS for at least 6 months were recruited via hospitals, psychotherapeutic practices and self-help organizations. Qualitative data were gathered via ideation discussions and prioritization tasks. Thematic analysis was conducted to gain insight on the needs of people with lived experiences. PPI was quantitatively evaluated with the Public and Patient Engagement Evaluation Tool. RESULTS: A total of 12 individuals participated (eight females, ages 22-66 years, duration of symptoms 1-43 years). Participants wanted to feel more supported, validated, in control and engaged with managing their health. Content-related preferences included education, self-help, social support and contact addresses. The majority of participants (>90%) experienced their involvement as worthwhile. CONCLUSIONS: To the best of our knowledge, this is one of the first studies describing PPI in intervention development for PSS. The involvement was perceived as a valuable contribution to the development process. PATIENT OR PUBLIC CONTRIBUTION: Adults with lived experiences were involved at the level of collaboration through the establishment of a participatory research team (PRT) and at the level of consultation through a workshop series, including one of the coauthors. They were involved in developing and validating intervention material and checking data interpretation.

Needs of multimorbid heart failure patients and their carers: a qualitative interview study and the creation of personas as a basis for a blended collaborative care intervention.

Introduction: Involving patients and carers in the development of blended collaborative care (BCC) interventions for multimorbid heart failure (HF) patients is recommended but rarely practised, and research on the patient perspective is scarce. The aim of this study is to investigate patients' and carers' care-related needs and preferences to better customize a novel international BCC intervention. Methods: A qualitative study design using framework analysis was employed. The study was performed in accordance with the EQUATOR standards for reporting qualitative research (SRQR). Patients aged at least 65 years with HF and at least two other physical diseases as well as their carers completed semistructured interviews in Germany, Italy, and Denmark. Based on these interviews, personas (prototype profiles of patients and carers) were created. Results: Data from interviews with 25 patients and 17 carers were analysed. Initially, seven country-specific personas were identified, which were iteratively narrowed down to a final set of 3 personas: (a) the one who needs and wants support, (b) the one who has accepted their situation with HF and reaches out when necessary, and (c) the one who feels neglected by the health care system. Carers identifying with the last persona showed high levels of psychological stress and a high need for support. Discussion: This is the first international qualitative study on patients' and carers' needs regarding a BCC intervention using the creation of personas. Across three European countries, data from interviews were used to develop three contrasting personas. Instead of providing "one size fits all" interventions, the results indicate that BCC interventions should offer different approaches based on the needs of individual patients and carers. The personas will serve as a basis for the development of a novel BCC intervention as part of the EU project ESCAPE (Evaluation of a patient-centred biopSychosocial blended collaborative CAre Pathway for the treatment of multimorbid Elderly patients).

How adults with suspected depressive disorder experience online depression screening: A qualitative interview study.

Background: While evidence on the effects and mechanisms of online depression screening is inconclusive, publicly available 'online depression tests' are already frequently used. To further a comprehensive understanding of online depression screening and evince the perspectives of those affected, we aimed to qualitatively explore how adults with undiagnosed but suspected depressive disorder experience the screening process. Methods: This study is a qualitative follow-up of a German-wide, 3-arm, randomised controlled trial on feedback after online depression screening conducted between Jan 2021 and Sep 2022. A subsample of 26 participants with undiagnosed but suspected depressive disorder (Patient Health Questionnaire-9 ≥ 10; no depression diagnosis/treatment within the last year) were purposefully selected based on maximum variation in gender, age, and study arm. In-depth semi-structured telephone interviews (mean = 37 min) were conducted approximately six months after screening. Data were analysed within a contextualist theoretical framework using inductive reflexive thematic analysis. Results: Participants were balanced in terms of gender (female/male, n = 15/11), age (range = 22 to 61 years), and study arm (no feedback/standard feedback/tailored feedback, n = 7/11/8). Reported experiences of online depression screening can be described as a two-step process: Step 1 is the initial reaction to the screening procedure and comprises the theme recognition of depressive symptoms: from denial to awareness. Step 2 describes a subsequent self-explorative process encompassing the themes cognitive positioning: rejection vs. acceptance, emotional reaction: between overload and empowerment, and personal activation: from reflection to action. Conclusions: Findings indicate that online depression screening with and without feedback of results is experienced as a two-step process promoting symptom recognition and subsequent self-exploration. While few participants reported negative effects, the majority described the screening process as insightful, empowering, and activating. Future research should determine to what extent online depression screening may pose a standalone form of low-threshold support for individuals with undiagnosed depressive disorder, while focusing as well on potential negative effects.

Nurses' experiences of a screening and associated psychosomatic consultation service for mental comorbidities in somatic care inpatients - a qualitative study.

Background: Screening for mental comorbidities and related liaison service can reduce hospital length of stay in somatic hospital care. To develop, test and sustain such health care services, stakeholder feedback is required. One of the most important stakeholders in general hospital care and health care processes are nurses. Aim: The aim of this study is to explore nurses' experiencess on standardized nurse-led screening for mental comorbidities and associated psychosomatic consultation service in routine somatic inpatient care. Method: Semi-structured qualitative interviews were conducted with 18 nurses that were involved in a nurse-led screening service for mental comorbidities on internal medicine or dermatological wards. Data were analyzed using thematic analysis. Results: Eight thematic groups were developed. On the one hand, participants reported benefits of screening: mental health education, general mental health awareness, holistic treatment approach, opportunity to build rapport with patients and reduction in workload. On the other hand, possible psychological effects of the intervention, reasons why patients may not want to be referred and application requirements to facilitate delivery were identified. None of the nurses opposed screening and associated psychosomatic consultation service. Conclusion: All nurses endorsed the screening intervention and considered it meaningful. Nurses particularly emphasized the potential for holistic patient care and nurses' improved skills and competencies, but partly critizised current application requirements. Relevance to clinical practice: This study adds on existent evidence on nurse-led screening for mental comorbidities and associated psychosomatic consultation service by emphasizing its potential to improve both patient care as well as nurses' perceived self-efficacy and job satisfaction. To take full advantage of this potential, however, usability improvements, regular supervision, and ongoing training for nurses need to be considered.

Integrated care for older multimorbid heart failure patients: protocol for the ESCAPE randomized trial and cohort study.

ESCAPE: Evaluation of a patient-centred biopsychosocial blended collaborative care pathway for the treatment of multimorbid elderly patients. THERAPEUTIC AREA: Healthcare interventions for the management of older patients with multiple morbidities. AIMS: Multi-morbidity treatment is an increasing challenge for healthcare systems in ageing societies. This comprehensive cohort study with embedded randomized controlled trial tests an integrated biopsychosocial care model for multimorbid elderly patients. HYPOTHESIS: A holistic, patient-centred pro-active 9-month intervention based on the blended collaborative care (BCC) approach and enhanced by information and communication technologies can improve health-related quality of life (HRQoL) and disease outcomes as compared with usual care at 9 months. METHODS: Across six European countries, ESCAPE is recruiting patients with heart failure, mental distress/disorder plus ≥2 medical co-morbidities into an observational cohort study. Within the cohort study, 300 patients will be included in a randomized controlled assessor-blinded two-arm parallel group interventional clinical trial (RCT). In the intervention, trained care managers (CMs) regularly support patients and informal carers in managing their multiple health problems. Supervised by a clinical specialist team, CMs remotely support patients in implementing the treatment plan-customized to the patients' individual needs and preferences-into their daily lives and liaise with patients' healthcare providers. An eHealth platform with an integrated patient registry guides the intervention and helps to empower patients and informal carers. HRQoL measured with the EQ-5D-5L as primary endpoint, and secondary outcomes, that is, medical and patient-reported outcomes, healthcare costs, cost-effectiveness, and informal carer burden, will be assessed at 9 and ≥18 months. CONCLUSIONS: If proven effective, the ESCAPE BCC intervention can be implemented in routine care for older patients with multiple morbidities across the participating countries and beyond.

The Treatment Expectation Questionnaire (TEX-Q): Validation of a generic multidimensional scale measuring patients' treatment expectations.

BACKGROUND: Patients' expectations, as a central mechanism behind placebo and nocebo effects, are an important predictor of health outcomes. Yet, theoretically based generic assessment tools allowing for an integrated understanding of expectations across conditions and treatments are lacking. Based on the preliminary 35-item version, this study reports the development and validation of the Treatment Expectation Questionnaire (TEX-Q), a generic, multidimensional self-report scale measuring patients' expectations of medical and psychological treatments. METHODS: The TEX-Q was developed in a validation sample of n = 251 patients undergoing different treatments using exploratory factor analyses and item analyses, as well as analysis of convergent and divergent validity. Confirmatory factor analysis was conducted in an independent sample of n = 303 patients undergoing cancer treatment. Two-weeks test-retest reliability was assessed in n = 28 psychosomatic outpatients. RESULTS: Factor analyses revealed six theoretically founded stable subscales. The TEX-Q assesses expectations of treatment benefit, positive impact, adverse events, negative impact, process and behavioural control with a total of 15 items. Results for the subscales and the sum score indicated good internal consistency (α = .71-.92), moderate to high test-retest reliability (r = .39-.76) as well as good convergent validity with regard to other expectation measures (r = .42-.58) and divergent validity with regard to measures of generalized expectations (r < .32) and psychopathology (r < .28). CONCLUSIONS: While further validation is needed, the results suggest that the TEX-Q is a valid and reliable scale for the generic, multidimensional assessment of patients' treatment expectations. The TEX-Q overcomes constraints of ad-hoc and disease-specific scales, while allowing to compare the impact of different expectation constructs across conditions and treatments.

Interdisciplinary and cross-sectoral perioperative care model in cardiac surgery: implementation in the setting of minimally invasive heart valve surgery (INCREASE)-study protocol for a randomized controlled trial.

BACKGROUND: Valvular heart diseases are frequent and increasing in prevalence. Minimally invasive heart valve surgery embedded in an interdisciplinary enhanced recovery after surgery (ERAS) program may have potential benefits with regard to reduced length of stay and improved patient reported outcomes. However, no prospective randomized data exist regarding the superiority of ERAS program for the patients' outcome. METHODS: We aim to randomize (1:1) a total of 186 eligible patients with minimally invasive heart valve surgery to an ERAS program vs. standard treatment at two centers including the University Medical Center Hamburg-Eppendorf, Germany, and the University Hospital Augsburg, Germany. The intervention is composed out of pre-, peri-, and postoperative components. The preoperative protocol aims at better preparation for the operation with regard to physical activity, nutrition, and psychological preparedness. Intraoperative anesthesiologic and surgical management are trimmed to enable an early extubation. Patients will be transferred to a specialized postoperative anesthesia care unit, where first mobilization occurs 3 h after surgery. Transfer to low care ward will be at the next day and discharge at the fifth day. Participants in the control group will receive treatment as usual. Primary endpoints include functional discharge at discharge and duration of in-hospital care during the first 12 months after index surgery. Secondary outcomes include health-related quality of life, health literacy, and level of physical activity. DISCUSSION: This is the first randomized controlled trial evaluating the effectiveness of an ERAS process after minimally invasive heart valve surgery. Interprofessional approach is the key factor of the ERAS process and includes in particular surgical, anesthesiological, physiotherapeutic, advanced nursing, and psychosocial components. A clinical implication guideline will be developed facilitating the adoption of ERAS model in other heart teams. TRIAL REGISTRATION: The study has been registered in ClinicalTrials.gov ( NCT04977362 assigned July 27, 2021).

Somatic symptom disorder: a scoping review on the empirical evidence of a new diagnosis.

BACKGROUND: In 2013, the diagnosis of somatic symptom disorder (SSD) was introduced into the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This review aims to comprehensively synthesize contemporary evidence related to SSD. METHODS: A scoping review was conducted using PubMed, PsycINFO, and Cochrane Library. The main inclusion criteria were SSD and publication in the English language between 01/2009 and 05/2020. Systematic search terms also included subheadings for the DSM-5 text sections; i.e., diagnostic features, prevalence, development and course, risk and prognostic factors, culture, gender, suicide risk, functional consequences, differential diagnosis, and comorbidity. RESULTS: Eight hundred and eighty-two articles were identified, of which 59 full texts were included for analysis. Empirical evidence supports the reliability, validity, and clinical utility of SSD diagnostic criteria, but the further specification of the psychological SSD B-criteria criteria seems necessary. General population studies using self-report questionnaires reported mean frequencies for SSD of 12.9% [95% confidence interval (CI) 12.5-13.3%], while prevalence studies based on criterion standard interviews are lacking. SSD was associated with increased functional impairment, decreased quality of life, and high comorbidity with anxiety and depressive disorders. Relevant research gaps remain regarding developmental aspects, risk and prognostic factors, suicide risk as well as culture- and gender-associated issues. CONCLUSIONS: Strengths of the SSD diagnosis are its good reliability, validity, and clinical utility, which substantially improved on its predecessors. SSD characterizes a specific patient population that is significantly impaired both physically and psychologically. However, substantial research gaps exist, e.g., regarding SSD prevalence assessed with criterion standard diagnostic interviews.

Clinical effectiveness of patient-oriented depression feedback in primary care: The empirical method of the GET.FEEDBACK.GP multicenter randomized controlled trial.

GET.FEEDBACK.GP1 is a multicenter randomized controlled trial testing the efficacy of patient-oriented depression feedback in primary care. This paper describes the complex methods and procedures of the trial. The primary outcome is depression severity six months after feedback, and we vary who is the target of the feedback as follows: no one receives feedback, only general practitioners receive feedback, and both patients and general practitioners receive feedback. The procedure includes a baseline assessment in primary care practices and three telephone follow-up interviews after one, six, and twelve months. The patients completed a baseline assessment, which determined their depression severity. Those with at least a moderate depression severity (PHQ-95 ≥ 10) were randomly allocated to three groups stratified by depression severity. A standardized mean difference of d = 0.25 with power 1 - ß = 0.80 required a total sample size of N = 699. The patients provided responses regarding the primary and secondary outcomes at follow-up. The extensive planning for GET.FEEDBACK.GP involved experts from diverse medical specialties and external corporations. Of particular importance were (a) blinding in the study inclusion and random assignment with data capture software, (b) representative and unbiased patient selection in practice waiting rooms, (c) a data management and safety plan supplied by a specialized trial center, and (d) the use of participant pseudonyms supplied by a specialized service (Mainzelliste). The data collection started in July 2019 and will continue until June 2022. Five university study centers in Germany are participating in the trial.

The efficacy of automated feedback after internet-based depression screening: Study protocol of the German, three-armed, randomised controlled trial DISCOVER.

BACKGROUND: Depression is one of the most disabling disorders worldwide, yet it often remains undetected. One promising approach to address both early detection and disease burden is depression screening followed by direct feedback to patients. Evidence suggests that individuals often seek information regarding mental health on the internet. Thus, internet-based screening with automated feedback has great potential to address individuals with undetected depression. OBJECTIVES: To determine whether automated feedback after internet-based depression screening reduces depression severity as compared to no feedback. METHODS: The internet-based, observer-blinded DISCOVER RCT aims to recruit a total of 1074 individuals. Participants will be screened for depression using the Patient Health Questionnaire (PHQ-9). In case of a positive screening result (PHQ-9 ≥ 10), participants with undetected depression will be randomised into one of three balanced study arms to receive either (a) no feedback (control arm), (b) standard feedback, or (c) tailored feedback on their screening result. The tailored feedback version will be adapted to participants' characteristics, i.e. symptom profile, preferences, and demographic characteristics. The primary hypothesis is that feedback reduces depression severity six months after screening compared to no feedback. The secondary hypothesis is that tailored feedback is more efficacious compared to standard feedback. Further outcomes are depression care, help-seeking behaviour, health-related quality of life, anxiety, somatic symptom severity, intervention acceptance, illness beliefs, adverse events, and a health economic evaluation. Follow-ups will be conducted one month and six months after screening by self-report questionnaires and clinical interviews. According to a statistical analysis plan, the primary outcome will be analysed on an intention-to-treat basis applying multilevel modelling. DISCUSSION: The results of the DISCOVER RCT will inform about how automated feedback after internet-based screening could improve early detection and resolution of depression. Ways of dissemination and how the trial can contribute to an understanding of help-seeking behaviour processes will be discussed. If the results show that automated feedback after internet-based depression screening can reduce depression severity, the intervention could be easily implemented and might substantially reduce the disease burden of individuals with undetected depression. ETHICAL APPROVAL: The study is approved by the Ethics Committee of the Hamburg Medical Association. TRIAL REGISTRATION: The trial was registered at ClinicalTrials.gov in November 2020 (identifier: NCT04633096).

[Early Detection of Psychological Comorbidity in Patients Admitted to Dermatological and Internal Medicine Wards: A New Care Model for Psychosomatic Consultation Service]. / Früherkennung von psychischer Komorbidität in der stationären dermatologischen und internistischen Versorgung: Darstellung eines neuen Versorgungskonzeptes.

This article explains the development and implementation of a psychosomatic screening and consultation service for inpatient somatic care. Approximately one in six somatic inpatients has a mental disorder. It is estimated that only half of these cases are properly identified. Consequently, a large proportion of patients remains untreated. To address this gap in care, a psychosomatic early detection programme was developed by an interdisciplinary working group. This programme is based on the Patient Health Questionnaire-4 (PHQ-4), a psychometrically very well evaluated ultra-short screening questionnaire for the detection of depressive and anxiety disorders. For implementation in routine inpatient care, the PHQ-4 was programmed as a form in the electronic medical record and administered by nursing staff during the admission interview. If the PHQ-4 screening result indicates the presence of a mental comorbidity and the patient expresses a wish for assessment of this disorder, a psychosomatic consultation is automatically ordered. The PHQ-4 was implemented into the clinical routine in four internal medicine and three dermatology wards of the University Medical Center Hamburg-Eppendorf. Documentation of the early diagnosis in the electronic patient record is a minimally costly, less time-consuming and practicable method of providing patients with holistic care through rapid interdisciplinary referral. An evaluation of cost-effectiveness, clinical efficiency, and acceptance is still pending.
