RESUMO
BACKGROUND: eHealth approaches show promising results for smoking cessation (SC). They can improve quit rates, but rigorous research is sparse regarding their effectiveness and the effects of their interactivity, tailoring, and use intensity. OBJECTIVE: We examined the effectiveness of Techniker Krankenkasse Smoking Cessation Coaching (TK-SCC), an internet-based, tailored, and interactive SC intervention. Our hypotheses were as follows: hypothesis 1, in the intervention group (IG; access to TK-SCC), a clinically relevant number of participants will be abstinent at the 12-month follow-up (T3); hypothesis 2, the number of abstinent participants will be significantly greater in the IG than the control group (CG) at T3; and hypothesis 3, in the IG, more intense use of TK-SCC will be positively associated with abstinence. METHODS: Individuals who smoke were randomized into the IG (563/1115, 50.49%) or CG (552/1115, 49.51%), which received a noninteractive, nontailored, and information-only web-based intervention. Data were collected before the intervention, at the postintervention time point (T1), at the 4-month follow-up (T2), and at T3. We tested hypothesis 1 through equivalence tests between the IG's success rate and success rates of comparable effective interventions reported in 2 current meta-analyses. For hypothesis 2, we conducted binary logistic regressions. For hypothesis 3, we assigned the IG participants to 1 of 4 user types and used binary logistic regressions with user types as the independent variable and smoking abstinence as the dependent variable. RESULTS: In the IG, 11.5% (65/563) and 11.9% (67/563) of participants were smoke free at T1 and T3, respectively. These values were statistically equivalent to the effects in the 2 meta-analyses, which reported 9% (z score=0.64, P=.74) and 10.9% (z score=-0.71, P=.24) success rates, respectively. In the CG, 6.2% (34/552) of the participants were smoke free at T1, which increased up to 8.2% (45/552) at T3. The difference between the IG and CG was statistically significant only at T1 (odds ratio [OR] 2.0, 99% CI 1.1 to 3.6; P=.002), whereas the effect was nonsignificant following α error corrections at T3 (OR 1.6, 99% CI 0.9 to 2.7; P=.02). In the IG, constant users of the program became smoke free significantly more often than rare users of the program (T1: OR 15.0, 99% CI 6.1 to 36.9; P<.001; T3: OR 6.5, 99% CI 2.8 to 15.5; P<.001). CONCLUSIONS: TK-SCC is effective for SC. However, its superiority compared with a minimal SC intervention could not be confirmed in the long term. Insufficient implementation of the techniques used and cotreatment bias could explain this outcome. Higher use intensity of TK-SCC was positively related to abstinence. Therefore, additional efforts to motivate users to adhere to intervention use as intended could improve the intervention's effectiveness.

BACKGROUND: The high proportion of people with overweight and obesity has become a worldwide problem in recent decades, mainly due to health consequences, such as cardiovascular diseases, neoplasia, and type 2 diabetes mellitus. Regarding effective countermeasures, the digitization of health services offers numerous potentials, which, however, have not yet been sufficiently evaluated. Web-based health programs are becoming increasingly interactive and can provide individuals with effective long-term weight management support. OBJECTIVE: The purpose of this randomized controlled clinical trial was to evaluate the effectiveness of an interactive web-based weight loss program on anthropometric, cardiometabolic, and behavioral variables and to compare it with a noninteractive web-based weight loss program. METHODS: The randomized controlled trial included people who were aged between 18 and 65 years (mean 48.92, SD 11.17 years) and had a BMI of 27.5 to 34.9 kg/m2 (mean 30.71, SD 2.13 kg/m2). Participants (n=153) were assigned to either (1) an interactive and fully automated web-based health program (intervention) or (2) a noninteractive web-based health program (control). The intervention program focused on dietary energy density and allowed for dietary documentation with appropriate feedback on energy density and nutrients. The control group only received information on weight loss and energy density, but the website did not contain interactive content. Examinations were performed at baseline (t0), at the end of the 12-week intervention (t1), and at 6 months (t2) and 12 months (t3) thereafter. The primary outcome was body weight. The secondary outcomes were cardiometabolic variables as well as dietary and physical activity behaviors. Robust linear mixed models were used to evaluate the primary and secondary outcomes. RESULTS: The intervention group showed significant improvements in anthropometric variables, such as body weight (P=.004), waist circumference (P=.002), and fat mass (P=.02), compared with the control group over the course of the study. The mean weight loss after the 12-month follow-up was 4.18 kg (4.7%) in the intervention group versus 1.29 kg (1.5%) in the control group compared with the initial weight. The results of the nutritional analysis showed that the energy density concept was significantly better implemented in the intervention group. Significant differences in cardiometabolic variables were not detected between the 2 groups. CONCLUSIONS: The interactive web-based health program was effective in reducing body weight and improving body composition in adults with overweight and obesity. However, these improvements were not associated with relevant changes in cardiometabolic variables, although it should be noted that the study population was predominantly metabolically healthy.

OBJECTIVE: The aim of the article was to describe the development of a training program to enhance the health literacy of patients with immunodeficiency. In addition, patient satisfaction and acceptance of the training will be evaluated. METHODS: Patients' needs were identified with a questionnaire (N=238). Additionally, interviews with clinical immunologists (N=5) and patients with common variable immunodeficiency (CVID) (N=9) were conducted. On this basis, the authors developed a manual for the intervention. It focuses on active communication with physicians as well as health-related communication at the workplace. The evaluation of patient satisfaction with the intervention was based on a questionnaire (N=49). RESULTS: The results show that the ratings of the patients were in the good to very good range (M=1.77; SD=0.38). From the analysis of the free text, hints for training improvement could be derived. CONCLUSION: Evaluation of the intervention showed that the new training was accepted and patients considered it comprehensible and relevant.

BACKGROUND: Hypertension is one of the key factors causing cardiovascular diseases. A substantial proportion of treated hypertensive patients do not reach recommended target blood pressure values. Shared decision making (SDM) is to enhance the active role of patients. As until now there exists little information on the effects of SDM training in antihypertensive therapy, we tested the effect of an SDM training programme for general practitioners (GPs). Our hypotheses are that this SDM training (1) enhances the participation of patients and (2) leads to an enhanced decrease in blood pressure (BP) values, compared to patients receiving usual care without prior SDM training for GPs. METHODS: The study was conducted as a cluster randomised controlled trial (cRCT) with GP practices in Southwest Germany. Each GP practice included patients with treated but uncontrolled hypertension and/or with relevant comorbidity. After baseline assessment (T0) GP practices were randomly allocated into an intervention and a control arm. GPs of the intervention group took part in the SDM training. GPs of the control group treated their patients as usual. The intervention was blinded to the patients. Primary endpoints on patient level were (1) change of patients' perceived participation (SDM-Q-9) and (2) change of systolic BP (24h-mean). Secondary endpoints were changes of (1) diastolic BP (24h-mean), (2) patients' knowledge about hypertension, (3) adherence (MARS-D), and (4) cardiovascular risk score (CVR). RESULTS: In total 1357 patients from 36 general practices were screened for blood pressure control by ambulatory blood pressure monitoring (ABPM). Thereof 1120 patients remained in the study because of uncontrolled (but treated) hypertension and/or a relevant comorbidity. At T0 the intervention group involved 17 GP practices with 552 patients and the control group 19 GP practices with 568 patients. The effectiveness analysis could not demonstrate a significant or relevant effect of the SDM training on any of the endpoints. CONCLUSION: The study hypothesis that the SDM training enhanced patients' perceived participation and lowered their BP could not be confirmed. Further research is needed to examine the impact of patient participation on the treatment of hypertension in primary care. TRIAL REGISTRATION: German Clinical Trials Register (DRKS): DRKS00000125.

Web-based lifestyle interventions are a new area of health research. This randomized controlled trial evaluated the effectiveness of an interactive web-based health program on physical fitness and health. N = 189 healthy adults participated in a 12-week interactive (intervention) or non-interactive (control) web-based health program. The intervention provided a web-based lifestyle intervention to promote physical activity and fitness through individualized activities as part of a fully automated, multimodal health program. The control intervention included health information. Cardiorespiratory fitness measured as maximum oxygen uptake (VO2max) was the primary outcome, while musculoskeletal fitness, physical activity and dietary behavior, and physiological health outcomes were assessed as secondary outcomes (t0: 0 months, t1: 3 months, t2: 9 months, t3: 15 months). Statistical analysis was performed with robust linear mixed models. There were significant time effects in the primary outcome (VO2max) (t0-t1: p = 0.018) and individual secondary outcomes for the interactive web-based health program, but no significant interaction effects in any of the outcomes between the interactive and non-interactive web-based health program. This study did not demonstrate the effectiveness of an interactive compared with a non-interactive web-based health program in physically inactive adults. Future research should further develop the evidence on web-based lifestyle interventions.
RESUMO
INTRODUCTION: Cardiovascular diseases are the most common cause of death in Germany and among the most frequent reasons for encounters in primary care. Most patients with cardiovascular risks (CVRs) have difficulties implementing health-promoting behavioural changes. In this study, a complex intervention containing evidence-based patient materials and structured follow-up consultations are intended to strengthen patients' self-management to improve health behaviour. METHODS AND ANALYSIS: In this cluster randomised controlled trial, we investigate the effects of the intervention "Decision aid, action planning and follow-up support for patients to reduce the 10-year risk of cardiovascular diseases" (DECADE) using a 2×2 design. All patients, including the control group (CG), receive a CVR calculation. Three intervention groups (IGs) receive one or both of two different components of the DECADE intervention: IG1 (patient materials), IG2 (follow-up consultations) and IG3 (patient materials and follow-up consultations). The study was planned to be conducted with 77 general practitioners in 3 German regions and a target sample size of 924 patients. The observation period for each patient amounts to 12 months with three patient surveys: baseline (t0), after 6 and 12 months (t1 and t2). The primary outcome is patient activation (Patient Activation Measure 13 (PAM13-D)) at t1. Secondary outcomes include PAM13-D at t2 and further patient-reported and clinical outcomes at t1 and t2. We will also analyse the cost-effectiveness of the intervention, the degree of usage and satisfaction with the intervention. ETHICS AND DISSEMINATION: The study was first approved by the lead ethics committee of the University of Freiburg on 15 April 2021 (vote number: 21-1078) and subsequently by the other ethics committees in the study regions (Ethics committee of medical association Baden-Württemberg (B-F-2021-078), Ethics Committee of the Technische Universität Dresden, Dresden (BO-EK-251052021), Ethics Committee of the State Chamber of Physicians of Saxony (EK-BR-92/21-1), Ethics Committee of the Hamburg Medical Association (2021-200013-BO-bet)). Informed consent is required for patients to participate in the study. The results of this study will be published in peer-reviewed journals and presented at congresses by the DECADE team. The DECADE lead management will communicate the results to the funder of this study.

BACKGROUND: Hypertension is one of the key factors causing cardiovascular diseases which make up the most frequent cause of death in industrialised nations. However about 60% of hypertensive patients in Germany treated with antihypertensives do not reach the recommended target blood pressure. The involvement of patients in medical decision making fulfils not only an ethical imperative but, furthermore, has the potential of higher treatment success. One concept to enhance the active role of patients is shared decision making. Until now there exists little information on the effects of shared decision making trainings for general practitioners on patient participation and on lowering blood pressure in hypertensive patients. METHODS/DESIGN: In a cluster-randomised controlled trial 1800 patients receiving antihypertensives will be screened with 24 h ambulatory blood pressure monitoring in their general practitioners' practices. Only patients who have not reached their blood pressure target (approximately 1200) will remain in the study (T1 - T3). General practitioners of the intervention group will take part in a shared decision making-training after baseline assessment (T0). General practitioners of the control group will treat their patients as usual. Primary endpoints are change of systolic blood pressure and change of patients' perceived participation. Secondary endpoints are changes of diastolic blood pressure, knowledge, medical adherence and cardiovascular risk. Data analysis will be performed with mixed effects models. DISCUSSION: The hypothesis underlying this study is that shared decision making, realised by a shared decision making training for general practitioners, activates patients, facilitates patients' empowerment and contributes to a better hypertension control. This study is the first one that tests this hypothesis with a (cluster-) randomised trial and a large sample size.

Personal behavior patterns, such as unhealthy diet and lack of physical activity, lead to the development of overweight and obesity. These are associated with other comorbidities, reduced quality of life, premature frailty and increased mortality. Personalized web-based interventions are promising in inducing behavioral change leading to effective reductions in body weight at relatively low costs. However, the long-term effects have not been thoroughly investigated. This work evaluates the effectiveness of web-based interactive weight loss coaching and compares it to a non-interactive web-based health program. Therefore, a randomized controlled trial (RCT) was implemented, measuring primary and secondary outcomes at four time points (program start; end of the 12-week-program; 6 months after program end, 12 months after program end). The net sample covered 1499 subjects in the intervention group and 1492 in the control group. On average, the IG was 43 years old (±13.6), 80.1% male, and had 86.4 kg body weight (±16.1) at baseline. The CG was 42.7 years old (±13.9), 79.5% male and had a mean body weight of 86.1 (±15.7). Multilevel analyses with fixed effects were carried out both from the perspective of an intention-to-treat (ITT) and a complete cases approach (CCA). In sum, our adjusted models suggest a weight loss of 0.4 kg per time point. At the end of the program, significant differences in weight loss in % to baseline (delta M = 1.8 in the CCA) were observed in favor of the intervention group. From a long-term perspective, no superiority of the intervention group in comparison to the control group could be found. More intensive use of the program was not statistically associated with higher weight loss.

This randomized, controlled clinical trial examined the impact of a web-based weight loss intervention on diet quality. Furthermore, it was investigated whether corresponding changes in diet quality were associated with changes in measures of cardiovascular risk profile. Individuals with a body mass index (BMI) of 27.5 to 34.9 kg/m2 and an age of 18 to 65 y were assigned to either an interactive and fully automated web-based weight loss program focusing on dietary energy density (intervention) or a non-interactive web-based weight loss program (control). Examinations were performed at baseline (t0), after the 12-week web-based intervention (t1), and after an additional 6 (t2) and 12 months (t3). Based on a dietary record, the Healthy Eating Index-NVS (HEI-NVS) was calculated and analyzed using a robust linear mixed model. In addition, bootstrapped correlations were performed independently of study group to examine associations between change in HEI-NVS and change in dietary, anthropometric, and cardiometabolic variables. A total of n = 153 participants with a mean BMI of 30.71 kg/m2 (SD 2.13) and an average age of 48.92 y (SD 11.17) were included in the study. HEI-NVS improved significantly in the intervention group from baseline (t0) to t2 (p = 0.003) and to t3 (p = 0.037), whereby the course was significantly different up to t2 (p = 0.013) and not significantly different up to t3 (p = 0.054) compared to the control group. Independent of study group, there was a significant negative association between change in HEI-NVS and dietary energy density. A higher total score in HEI-NVS did not correlate with improvements in cardiovascular risk profile. The interactive and fully automated web-based weight loss program improved diet quality. Independent of study group, changes in HEI-NVS correlated with changes in energy density, but there was no association between improvements in HEI-NVS and improvements in cardiovascular risk profile.

Web-based lifestyle interventions have attracted considerable research interest. Available evidence on such interventions suggests health-promoting effects, but further research is needed. Therefore, this study aims to investigate short-, medium-, and long-term health effects of a web-based health program ("TK-HealthCoach", TK-HC) offered by a national statutory health insurance fund (Techniker Krankenkasse, TK). The study comprises two randomized controlled clinical trials to evaluate the health goals "Increasing Fitness" (Fclin) and "Losing and Maintaining Weight" (Wclin). A total of n = 186 physically inactive (Fclin) and n = 150 overweight or obese (Wclin) adults will be randomly assigned to a 12-week interactive (TK-HC) or non-interactive web-based health program using permuted block randomization with a 1:1 allocation ratio. Primary outcomes include cardiorespiratory fitness (Fclin) and body weight (Wclin). Secondary outcomes comprise musculoskeletal fitness (Fclin), physical activity and dietary behavior, anthropometry, blood pressure, blood levels, and vascular health (Fclin, Wclin). All outcomes will be measured before and after the 12-week intervention and after a 6- and 12-month follow-up. Additionally, usage behavior data on the health programs will be assessed. Linear mixed models (LMMs) will be used for statistical analysis. Findings of this study will expand the available evidence on web-based lifestyle interventions.

BACKGROUND: A healthy lifestyle can help prevent diseases that impair quality of life and lead to premature death. The Techniker health insurance fund offers a comprehensive online health program to support users in achieving their health goals of Increasing Fitness, Losing and Maintaining Weight, or Smoking Cessation. METHODS: The aim of this study is to test the long-term effectiveness of the web-based TK-HealthCoach with regard to the primary outcomes of increased physical activity, sustainable weight reduction, and smoking abstinence. We are conducting three interconnected, randomized controlled trials (RCT), one for each health goal, within which participants are allocated to an intervention group (interactive online health program) or a control group (non-interactive online health program). The effects of the intervention groups compared to the control groups will be analyzed by multi-level models for change. Participants' data are captured via online questionnaires before the program starts (baseline t0), again when it ends (t1), and later at two follow-up surveys (t2 and t3); the latter 12 months after t1. We are documenting socio-demographic, health-related, and psychological variables as well as usage behavior data of the programs. According to our sample size calculation, we have to enroll 1114 participants in each Losing and Maintaining Weight and Increasing Fitness RCT and 339 participants in the Smoking Cessation RCT. Additionally, 15-20 participants in the interactive smoking-cessation program will be invited to qualitative telephone interviews with the aim to obtain detailed information concerning utilization, compliance, and satisfaction. The online RCTs' inclusion criteria are: adults of each gender regardless of whether they are insured with Techniker health insurance fund. Persons with impairments or pre-existing conditions require a medical assessment as to whether the program is suitable for them. Specific exclusion criteria apply to each program/RCT. DISCUSSION: We assume that study participants will improve their health behavior by using the offered online health programs and that each health goal's intervention group will reveal advantages regarding the outcome variables compared to the control groups. Study enrollment started on January 1, 2020. TRIAL REGISTRATION: German Clinical Trials Register, Universal Trial Number (UTN): U1111-1245-0273 . Registered on 11 December 2019.

BACKGROUND: Late-life depression is a highly prevalent disorder that causes a large economic burden. A stepped collaborative care program was set up in order to improve care for patients with late-life depression in primary care in Germany: GermanIMPACT is the adaption of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) program that has already been established in primary care in the USA. The aim of this study was to determine the cost-effectiveness of GermanIMPACT compared with treatment as usual from a societal perspective. METHODS: This study is part of a 12-month bi-centric cluster-randomized controlled trial aiming to assess the effectiveness of GermanIMPACT compared with treatment as usual among patients with late-life depression. A cost-effectiveness analysis using depression-free days (DFDs) was performed. Net-monetary benefit (NMB) regressions adjusted for baseline differences for different willingness-to-pay (WTP) thresholds were conducted and cost-effectiveness acceptability curves were constructed. RESULTS: In total, n = 246 patients (intervention group: n = 139; control group: n = 107) with a mean age of 71 from 71 primary care practices were included in the analysis. After 12 months, adjusted mean differences in costs and DFDs between intervention group and control group were +354 and +21.4, respectively. Only the difference in DFDs was significant (p = 0.022). According to the unadjusted incremental cost-effectiveness ratio, GermanIMPACT was dominant compared with treatment as usual. The probability of GermanIMPACT being cost-effective was 80%, 90% or 95% if societal WTP per DFD was ≥70, ≥110 or ≥180, respectively. CONCLUSION: Evidence for cost-effectiveness of GermanIMPACT relative to treatment as usual is not clear. Only if societal WTP was ≥180 for an additional DFD, GermanIMPACT could be considered cost-effective with certainty.

BACKGROUND: Cardiovascular diseases are among the most common causes of death in industrialized countries. The goal of the DECADE study ("decision aid, action planning, and follow-up support for patients to reduce the 10-year risk of cardiovascular diseases") is to improve patient activation and health-related behavior by means of structured cardiovascular risk counseling and DECADE brochures. In this pilot study, the applicability of DECADE and the potential effects of the intervention on patients with cardiovascular risk factors were investigated. METHODS: 87 patients were included in the two-arm, randomized, controlled pilot study. All of them participated in four structured counseling sessions. The A+D group received DECADE brochures (intervention group), while the A group did not (control group). The change in patient activation four months later (PAM13-D) was the primary endpoint. Secondary endpoints included, among others, changes in health status and health-related behavior, goal achievement, and patient satisfaction. These changes were studied in an intention-to-treat analysis. RESULTS: Endpoint data were available for 78 patients (38 in the A+D group and 40 in the A group) at four months. The use of DECADE brochures had a significant beneficial effect on PAM13-D scores (an increase of 3.30 points, p = 0.023), corresponding to a moderate effect size of 0.54. Positive trends were seen in most of the other endpoints. The improved patient activation was associated with an overall reduction of risk factors. CONCLUSION: This pilot study shows that DECADE can support patient activation. The effects can be expected to be stronger in a larger study and in comparison to usual care. If this can be confirmed, DECADE should be embedded in routine patient care.

BACKGROUND: Depression in the elderly is mainly treated by primary care physicians; the treatment is often suboptimal because of the limited resources available in pri- mary care. New models of care in which treatment by a primary care physician is supplemented by the provision of brief, low-threshold interventions mediated by care managers are showing themselves to be a promising approach. METHODS: In this open, cluster-randomized, controlled study, we sought to determine the superiority of a model of this type over the usual form of treatment by a primary care physician. Patients in primary care aged 60 and above with moderate depres- sive manifestations (PHQ-9: 10-14 points) were included in the study. The primary endpoint was the percentage of patients in remission (score <5 on the Patient Health Questionnaire, PHQ-9) after the end of the intervention (12 months after baseline). The study was registered in the German Clinical Studies Registry (Deutsches Register für Klinische Studien) with the number DRKS00003589. RESULTS: 71 primary care physicians entered 248 patients in the study, of whom 109 were in the control group and 139 in the intervention group. In an intention-to-treat analysis, the remission rate at 12 months was 25.6% (95% confidence interval [18.3; 32.8]) in the intervention group and 10.9% [5.4; 16.5]) in the control group (p = 0.004). CONCLUSION: This study demonstrates the superiority of the new care model in the primary care setting in Germany, as has been found in other countries.

BACKGROUND: A healthy lifestyle can reduce cardiovascular risk (CVR) and prevent premature death. Usually most patients at increased CVR have difficulties implementing the necessary health behavior changes, such as smoking cessation, increasing of physical activity, healthy diet, stress reduction, etc. In this pilot study, a new intervention (DECADE) that includes a cardiovascular risk calculation, evidence-based decision aids, action planning, and follow-up support for patients to reduce their 10-year risk of cardiovascular diseases will be tested in primary care. The objectives of this trial are to test (1) the feasibility of the study design in preparation for the main trail including (2) the usability and acceptance of DECADE, and (3) initial data to ascertain that changes can be observed in these patients. METHODS: This randomized controlled pilot trial will generate initial data on the potential effects of DECADE on patients' self-evaluated activity and behavior change as well as on clinical outcomes such as blood pressure, cholesterol, body mass index (BMI), HbA1C, and CVR score. In the qualitative part of the study, we will analyze data collected in semi-structured interviews with participating general practitioners (GP) and in patient questionnaires. DISCUSSION: The outcomes of this pilot study will indicate whether DECADE is a promising intervention in the domain of patient-centered prevention of cardiovascular diseases (CVD) and whether a larger multi-center randomized controlled trial is feasible.

RESUMO
BACKGROUND: Depression is a very common disease among the elderly. Various studies demonstrated the need to improve the care for elderly depressed patients. Within the GermanIMPACT trial specifically trained care managers were engaged to cooperate with general practitioners (GPs). This study investigates how GPs evaluate this cooperation and their attitude towards collaborative care. METHODS: To explore the perspective of GPs a qualitative study design with semi-structured interviews was chosen. The guideline-based interviews were conducted with GPs from the intervention group, the control group and with GPs who had decided not to participate in the trial. The interviews were audio-taped, fully transcribed and analysed. RESULTS: Eighteen GPs were interviewed. Almost all GPs from the intervention group appreciated the support by care managers. Advantages they mentioned included their own relief by the committed conversation between patient and care manager, the continuous monitoring of the patients as well as the regular feedback via protocols. GPs who refused to take part in the study expressed different attitudes towards collaborative care. CONCLUSION: Due to the general overall positive valuation of care managers as well as their positive attitude towards collaborative care a continuation of the IMPACT program in Germany should be considered. More investigation needs to be done to answer the question how care managers can be integrated in everyday primary care.

BACKGROUND: Depression is not a normal side effect of aging, however it is one of the most prevalent mental health issues in later life, imposing a tremendous burden on patients, their families, and the healthcare system. We describe the experimental implementation of a collaborative, stepped-care model for the treatment of late-life depression (GermanIMPACT trial) in the German primary care context. GermanIMPACT was developed as an adaptation of a successful and widely used American model. The aim of the study is to evaluate the model's applicability to the German primary care setting and its cost-effectiveness. METHODS/DESIGN: The study will be conducted as a cluster-randomized controlled trial comparing the development of depressive symptoms in primary care patients who either receive treatment as usual (control arm) or treatment according to the GermanIMPACT model (intervention arm). In two German cities (Freiburg and Hamburg), a total of 60 general practice offices will be selected and randomized. Each general practice office will be asked to enroll five patients into the trial who are 60 years of age or older and who show moderate depressive symptoms in the scope of a diagnosed depressive episode, recurrent depressive disorder, or dysthymia. General practices in the control arm will provide treatment as usual; general practices in the intervention arm will work closely with a specially trained care manager and a supervising mental health specialist. Evidence-based elements of the treatment plan manual include patient education, identification and integration of positive activities into the daily routine, relapse prevention, and training of problem-solving techniques as needed. The intervention period per patient will be one year. Data will be collected at baseline, 6, and 12 months. Primary outcome is the patient-reported change of depressive symptoms (Patient Health Questionnaire, PHQ-9). Secondary outcomes include measures of quality of life, anxiety, depression-related behavior, problem-solving skills, resilience, and an overall economic evaluation of the program. DISCUSSION: The GermanIMPACT trial will provide evidence about the effectiveness, feasibility, and cost-effectiveness of collaborative stepped care in treating late-life depression in German primary care. Positive results will be a first step toward integrating specialized depression care managers into the primary care setting.
