Abstract Background Though Dialectical Behavior Therapy (DBT) and other treatment models for individuals with Borderline Personality Disorder (BPD) have shown to be efficient in inpatient and outpatient settings, there is a general shortage of these treatments. In Germany, most resources are spent on inpatient treatments and unspecific crisis interventions, while it is difficult to implement the necessary team structures in an outpatient setting. This study is testing an alternative approach focussing on outpatient treatment: Integrated Care Borderline (ICB) provides DBT for persons with severe BPD within the structures of an Assertive Community Treatment (ACT). ICB is team-based, integrating psychiatric and social support as well as crisis interventions into a DBT-strategy. Methods ICB was compared to TAU in a prospective, randomized controlled trial. This study is part of RECOVER, a comprehensive stepped care approach in Germany, which enrolled a total of 891 participants. 146 persons were diagnosed with BPD as main diagnosis. Of these, 100 were allocated to the highest level of severe mental illness (SMI) and randomly assigned to either ICB (n = 50) or TAU (n = 50). Data were collected at baseline and 12 months later. The main outcomes were psychosocial functioning (GAF), severity of BPD (BSL-23) and other mental symptoms (BSI, PHQ-9, GAD-7, self-harm), employment status (VILI), as well as hospital days and associated costs. Results Data show a significant increase of psychosocial functioning and a significant decrease of BPD and other psychiatric symptoms in both groups (r = .28 – .64), without any significant differences between the groups. The proportion of self-harming persons decreased in both groups without statistical significance. Patients were significantly more likely to be employed after a year of treatment in ICB (p = .001), but not in the TAU group (p = .454). Analyses showed a significant difference between the groups (p = .032). Moreover, psychiatric hospital days were significantly reduced in ICB (-89%, p

Abstract Background Orthogeriatric co-management (OGCM) addresses the special needs of geriatric fracture patients. Most of the research on OGCM focused on hip fractures while results concerning other severe fractures are rare. We conducted a health-economic evaluation of OGCM for pelvic and vertebral fractures. Methods In this retrospective cohort study, we used German health and long-term care insurance claims data and included cases of geriatric patients aged 80 years or older treated in an OGCM (OGCM group) or a non-OGCM hospital (non-OGCM group) due to pelvic or vertebral fractures in 2014–2018. We analyzed life years gained, fracture-free life years gained, healthcare costs, and cost-effectiveness within 1 year. We applied entropy balancing, weighted gamma and two-part models. We calculated incremental cost-effectiveness ratios and cost-effectiveness acceptability curves. Results We included 21,036 cases with pelvic (71.2% in the OGCM, 28.8% in the non-OGCM group) and 33,827 with vertebral fractures (72.8% OGCM, 27.2% non-OGCM group). 4.5–5.9% of the pelvic and 31.8–33.8% of the vertebral fracture cases were treated surgically. Total healthcare costs were significantly higher after treatment in OGCM compared to non-OGCM hospitals for both fracture cohorts. For both fracture cohorts, a 95% probability of cost-effectiveness was not exceeded for a willingness-to-pay of up to €150,000 per life year or €150,000 per fracture-free life year gained. Conclusion We did not obtain distinct benefits of treatment in an OGCM hospital. Assigning cases to OGCM or non-OGCM group on hospital level might have underestimated the effect of OGCM as not all patients in the OGCM group have received OGCM.

Abstract Orthogeriatric co-management (OGCM) describes a collaboration of orthopedic surgeons and geriatricians for the treatment of fragility fractures in geriatric patients. While its cost-effectiveness for hip fractures has been widely investigated, research focusing on fractures of the upper extremities is lacking. Thus, we conducted a health economic evaluation of treatment in OGCM hospitals for forearm and humerus fractures. In a retrospective cohort study with nationwide health insurance claims data, we selected the first inpatient stay due to a forearm or humerus fracture in 2014–2018 either treated in hospitals that were able to offer OGCM (OGCM group) or not (non-OGCM group) and applied a 1-year follow-up. We included 31,557 cases with forearm (63.1% OGCM group) and 39,093 cases with humerus fractures (63.9% OGCM group) and balanced relevant covariates using entropy balancing. We investigated costs in different health sectors, length of stay, and cost-effectiveness regarding total cost per life year or fracture-free life year gained. In both fracture cohorts, initial hospital stay, inpatient stay, and total costs were higher in OGCM than in non-OGCM hospitals. For neither cohort nor effectiveness outcome, the probability that treatment in OGCM hospitals was cost-effective exceeded 95% for a willingness-to-pay of up to €150,000. We did not find distinct benefits of treatment in OGCM hospitals. Assigning cases to study groups on hospital-level and using life years and fracture-free life years, which might not adequately reflect the manifold ways these fractures affect the patients’ health, as effectiveness outcomes, might have underestimated the effectiveness of treatment in OGCM hospitals.

Abstract Background Older people receiving home-based care (HBC) often face barriers to access preventive oral health care (OHC) and dental treatments. Leading to deterioration of their oral healthcare. It is further deteriorated by factors such as increasing burden of systemic diseases, medicinal side effects, limited mobility, financial constraints and lack of professional OHC at home. Older people also struggle to maintain necessary daily oral hygiene, leading to malnutrition, weight loss, and a risk of a further health degradation. This cross-sectional survey aimed to investigate the oral health-related quality of life (OHRQoL) and their associated factors in HBC recipients. Methods 5,280 older people (≥ 60 years) living in Hamburg, who were in need of care and insured with statutory health insurance DAK-Gesundheit received the questionnaire, which included the German version of the Oral Health Impact Profile (OHIP G-14) and, the EQ-5D health-related quality of life (HRQoL) measure as well as further questions regarding the extent of informal social support, subjective oral health status, oral health behaviour, subjective cognitive status, and socio-demographic variables. Results The participants (n = 1,622) had a median age of 83.2 years, with 72.0% of the sample being female. Nearly two thirds of the sample reported that their independence or abilities were significantly impaired (care level 2). Regarding oral health impacts, 40.0% of the participants reported experiencing at least one of the fourteen possible prevalent impacts of the OHIP-G14 fairly often or very often. A multivariate regression model on the severity of oral health impacts revealed, that a better HRQoL, a positive perception of one’s own dental status, fewer visits to dental practices, and no need for support in OHC were associated with better OHRQoL. Conversely, respondents with a negative perception of their oral health status, more frequent visits to a dental practice, a need for support in OHC, and subjective memory impairment showed poorer OHRQoL. Conclusions The results highlight the risk for poor oral health among older people in HBC. We conclude that there is an urgent need to prioritise oral health, especially as poor oral health can further compromise the systemic wellbeing of these already care dependent population.

Abstract Background In Germany, geriatricians deliver acute geriatric care during acute hospital stay and post-acute rehabilitation after transfer to a rehabilitation clinic. The rate patients receive acute geriatric care (AGC) or are transferred to post-acute rehabilitation (TPR) differs between hospitals. This study analyses the association between the two geriatric treatment systems (AGC, TPR) and second hip fracture in patients following an index hip fracture. Methods Nationwide health insurance data are used to identify the rate of AGC and TPR per hospital following hip fracture surgery in patients aged ≥ 80 years. Outcomes are a second hip fracture after surgery or after discharge within 180 or 360 days and new specific anti-osteoporotic drugs. Cox proportional hazard models and generalised linear models are applied. Results Data from 29,096 hip fracture patients from 652 hospitals were analysed. AGC and TPR are not associated with second hip fracture when follow-up started after surgery. However, during the first months after discharge patients from hospitals with no AGC or low rates of TPR have higher rates of second hip fracture than patients from hospitals with high rates of AGC or high rates of TPR (Hazard Ratio (95% CI) 1.35 (1.01–1.80) or 1.35 (1.03–1.79), respectively). Lower rates of AGC are associated with lower probabilities of new prescriptions of specific anti-osteoporotic drugs. Conclusions Our study suggests beneficial relationships of geriatric treatment after hip fracture with a) the risk of second hip fractures during the first months after discharge and b) an improvement of anti-osteoporotic drug treatment.

Abstract Background Effective care coordination may increase clinical efficiency, but its measurement remains difficult. The established metric “care density” (CD) measures care coordination based on patient-sharing among physicians, but it may be too rigid to generalize across disorders and countries. Therefore, we propose an extension called fragmented care density (FCD), which allows varying weights for connections between different types of providers. We compare both metrics in their ability to predict hospitalizations due to schizophrenia. Methods We conducted a longitudinal cohort study based on German claims data from 2014 through 2017 to predict quarterly hospital admissions. 21,016 patients with schizophrenia from the federal state Baden-Württemberg were included. CD and FCD were calculated based on patient-sharing networks. The weights of FCD were optimized to predict hospital admissions during the first year of a 24-month follow-up. Subsequently, we employed likelihood ratio tests to assess whether adding either CD or FCD improved a baseline model with control variables for the second follow-up year. Results The inclusion of FCD significantly improved the baseline model, Χ2(1) = 53.30, p

Abstract Background Refugee populations have an increased risk for mental disorders, such as depression, anxiety, and posttraumatic stress disorders. Comorbidity is common. At the same time, refugees face multiple barriers to accessing mental health treatment. Only a minority of them receive adequate help. The planned trial evaluates a low-threshold, transdiagnostic Internet-based treatment. The trial aims at establishing its efficacy and cost-effectiveness compared with no treatment. Methods N = 131 treatment-seeking Arabic- or Farsi-speaking patients, meeting diagnostic criteria for a depressive, anxiety, and/or posttraumatic stress disorder will be randomized to either the intervention or the waitlist control group. The intervention group receives an Internet-based treatment with weekly written guidance provided by Arabic- or Farsi-speaking professionals. The treatment is based on the Common Elements Treatment Approach (CETA), is tailored to the individual patient, and takes 6–16 weeks. The control group will wait for 3 months and then receive the Internet-based treatment. Discussion The planned trial will result in an estimate of the efficacy of a low-threshold and scalable treatment option for the most common mental disorders in refugees.

Abstract Background Refugees are at high risk for developing mental illnesses. Due to language and cultural barriers, there is need for specifically adapted therapeutic procedures for refugees in inpatient mental health care settings. Internet-based applications in refugee mother tongues have the potential to improve the outcomes of mental health care for this vulnerable population. The key research question of the present implementation study is whether the newly developed “blended ALMAMAR” app for Arabic and Farsi speaking refugees in Germany is used and accepted by patients and professionals in routine inpatient mental health care (blended care). Methods We present the design of an observational, prospective multicenter implementation study in eight psychiatric hospitals. We plan to recruit 100 Farsi or Arabic speaking refugees receiving in-patient treatment due to depression, anxiety disorder, posttraumatic stress disorder or substance use disorders. These patients will get access to the “blended ALMAMAR” app during their inpatient stay in a blended-care approach. We will assess the usage (e.g., duration and frequency of use of the app) as well as subjective acceptability and usability of the intervention. To identify sociodemographic and clinical factors associated with “blended ALMAMAR” usage, we will also perform clinical and questionnaire assessments. Discussion The newly developed “blended ALMAMAR” app may help to close communication gaps for the hard-to reach and vulnerable group of refugees in inpatient mental health care. It is the first blended-care intervention that addresses severely mentally ill refugees in an inpatient psychiatric setting in Germany.

Abstract Background Health economic research is still facing significant problems regarding the standardization and international comparability of health care services. As a result, comparative effectiveness studies and cost-effectiveness analyses are often not comparable. This study is part of the PECUNIA project, which aimed to improve the comparability of economic evaluations by developing instruments for the internationally standardized measurement and valuation of health care services for mental disorders. The aim of this study was to identify internationally relevant services in the health and social care sectors relevant for health economic studies for mental disorders. Methods A systematic literature review on cost-of-illness studies and economic evaluations was conducted to identify relevant services, complemented by an additional grey literature search and a search of resource use measurement (RUM) questionnaires. A preliminary long-list of identified services was explored and reduced to a short-list by multiple consolidation rounds within the international research team and an external international expert survey in six European countries. Results After duplicate removal, the systematic search yielded 15,218 hits. From these 295 potential services could be identified. The grey literature search led to 368 and the RUM search to 36 additional potential services. The consolidation process resulted in a preliminary list of 186 health and social care services which underwent an external expert survey. A final consolidation step led to a basic list of 56 services grouped into residential care, daycare, outpatient care, information for care, accessibility to care, and self-help and voluntary care. Conclusions The initial literature searches led to an extensive number of potential service items for health and social care. Many of these items turned out to be procedures, interventions or providing professionals rather than services and were removed from further analysis. The resulting list was used as a basis for typological coding, the development of RUM questionnaires and corresponding unit costs for international mental health economic studies in the PECUNIA project.

Abstract Background Autism refers to a neurodevelopmental condition with characteristic impairments in social interaction and communication, restrictive and repetitive behaviors, as well as difficulties in sensory information processing and daily living skills. Even though symptoms persist from early childhood throughout the lifespan and often require long-term support, there is a lack of mental health services that sufficiently meet the needs of autistic adults. Previous evidence suggested individual, professional and structural barriers to healthcare for autistic adults. Here, using a peer research approach, we sought to systematically investigate barriers and needs in mental healthcare of autistic adults in Germany at the three relevant levels (individual, professional, structural) and from three relevant perspectives (autistic adults, relatives and healthcare providers), in order to obtain specific recommendations for optimized healthcare. Methods Maximum variation sampling was used to account for the complexity of the research field. Semi-structured, open-ended interviews were conducted with autistic adults (n = 15) and focus groups with relatives/partners (n = 12), and healthcare providers of several professions (n = 15). Data analysis was performed using the codebook approach of thematic analysis. Results Poor mental healthcare of autistic adults in Germany was characterized by six central and overarching themes: (i) lack of knowledge about autism, (ii) a need for increased participation/involvement, (iii) consideration of autism-specific needs in treatment, (iv) lack of services, (v) limited access to services, and (vi) improvement of stakeholder collaboration. Themes were similarly reported across participants, emphasizing dissatisfaction in all stakeholders. Conclusions We identified major barriers to mental healthcare for autistic adults in Germany that affect autistic adults, but are also of concern to relatives and healthcare providers. Our results point to specific and generic areas for improvement, independent of stakeholder perspectives, which could guide future development of needs- and evidence-based services, recommendations and guidelines of mental healthcare for people with autism across the lifespan.

Abstract Background The EQ-5D is a generic questionnaire providing a preference-based index score applicable to cost-utility analysis. This is the first study to validate the EQ-5D in patients with somatoform disorders. Methods Data of the EQ-5D descriptive system, the British and the German EQ-5D index and the EQ Visual Analogue Scale, the Patient Health Questionnaire 15, the Patient Health Questionnaire 9, the Whiteley Index 7 and the Short Form 36 were collected from 294 patients at baseline, 244 at 6 months and 256 at 12 months after baseline. The discriminative ability of the EQ-5D was evaluated by comparison with a general population sample and by the ability to distinguish between different symptom severities. Convergent validity was analysed by assessing associations between the EQ-5D and the other instruments. Responsiveness was evaluated by analysing the effects on scores between two measurements in groups of patients reporting worse, same or better health. The Bonferroni correction was employed. Results For all items of the EQ-5D except ‘self-care’, patients with somatoform disorders reported more problems than the general population. The EQ-5D showed discriminative ability in patients with different symptom severities. For nearly all reference instruments there were significant differences in mean scores between respondents with and without problems in the various EQ-5D items and strong correlations with the EQ Visual Analogue Scale and the EQ-5D index scores. Evidence for the responsiveness of the EQ-5D could only be found for patients with better health; effects were medium at the utmost. Conclusions The EQ-5D showed a considerable validity and a limited responsiveness in patients with somatoform disorders. Trial registration Current Controlled Trials ISRCTN55280791

Abstract Background Psychiatric comorbidity is common in back pain patients undergoing disc surgery and increases economic costs in many areas of health. The objective of this study was to analyse psychiatric comorbidity as predictor of direct and indirect costs in back pain patients undergoing disc surgery in a longitudinal study design. Methods A sample of 531 back pain patients was interviewed after an initial disc surgery (T0), 3 months (T1) and 15 months (T2) using the Composite International Diagnostic Interview to assess psychiatric comorbidity and a modified version of the Client Sociodemographic and Service Receipt Inventory to assess resource utilization and lost productivity for a 3-month period prior interview. Health care utilization was monetarily valued by unit costs and productivity by labour costs. Costs were analysed using random coefficient models and bootstrap techniques. Results Psychiatric comorbidity was associated with significantly (p Conclusion Psychiatric comorbidity presents an important predictor of direct and indirect costs in back pain patients undergoing disc surgery, even if patients do not utilize mental health care. This effect seems to be stable over time. More attention should be given to psychiatric comorbidity and cost-effective treatments should be applied to treat psychiatric comorbidity in back pain patients undergoing disc surgery to reduce health care utilization and costs associated with psychiatric comorbidity.

IntroductionFamily members of autistic individuals often provide support for their autistic relative throughout the lifespan which can lead to massive burden themselves. Reduced health-related Quality of Life (HRQoL) in family caregivers is assumed; however, only a handful studies on the HRQoL of family caregivers providing care to adult relatives exist as opposed to autistic children. Thus, the current study aimed to (i) investigate the current state of physical and mental HRQoL of family caregivers of autistic adults compared to the general population, and (ii) examine caregiver-related (e.g., age, subjective caregiver burden) and care recipient-related variables (e.g., symptom severity, utilization of formal services) explaining variance in the caregivers’ HRQoL.MethodsN = 149 family caregivers completed a nationwide online survey, including the Short-Form Health Survey (SF-8) in order to assess the HRQoL. T-tests were used to compare the HRQoL of family caregivers with the general population. Bivariate correlational and multiple linear regression analyses were conducted in order to identify predictors explaining variance in family caregivers’ HRQoL.ResultsFamily caregivers of autistic adults reported significantly lower physical (M = 46.71, SD = 8.72, Cohen’s d = 0.42) and mental HRQoL (M = 40.15, SD = 11.28, Cohen’s d = 1.35) compared to the general population. Multiple linear regression with the mental HRQoL as the outcome showed a significant model (F(11, 95) = 5.53, p < .001, adj. R2 = .32) with increased subjective burden explaining most of the variance in mental HRQoL (ß = .32, GDW = .141, p < .001). Multiple linear regression analysis with the outcome physical HRQoL did not reveal a statistically significant model (F(11,95) = 1.09, p = .38). However, bivariate analyses also showed a positive correlation with the subjective caregiver burden (r= .20, p < .05).DiscussionFindings highlight the need to consider HRQoL (and caregiver burden) of family caregivers of autistic adults in several healthcare settings to monitor a potential comprised health status in early stages, with the long-term goal to improve family caregivers’ HRQoL.

Introduction People receiving home care usually have complex healthcare needs requiring the involvement of informal caregivers and various health professionals. In this context, successful collaboration is an important element of person-centred care, which is often insufficiently implemented. Consequences might be found in avoidable hospitalisations. The aim of the study is to develop a care concept to improve person-centred interprofessional collaboration for people receiving home care considering the perspectives of all person groups involved.Methods and analysis This study uses a mixed-methods design consisting of a literature review, several qualitative inquiries, a cross-sectional quantitative study and a final structured workshop. After a literature review (work package (WP) 1), we will explore the perspectives of people receiving home care (n=20), their relatives (n=20) and representatives of statutory health insurances (n=5) in semistructured interviews (WP2). Moreover, 100 individuals of each group (people receiving home care, relatives, registered nurses, general practitioners and therapists) involved in home care will answer a survey on collaboration that will be analysed descriptively (WP3). Additionally, monoprofessional focus groups (n=9) of registered nurses, general practitioners and therapists, respectively, will discuss current practices. Data will be analysed by qualitative content analysis. Best practice cases (n=8) will be analysed by a case-based qualitative content analysis based on data of observations of home visits and interviews (WP4). The findings of WP2 will be discussed in mixed focus groups (n=4) with 10 participants each (WP5). Considering the results of joint displays of WP3, WP4 and WP5, the interprofessional care concept and its implementation will be elaborated in an expert workshop (WP6).Ethics and dissemination Ethical approval was obtained from all ethics committees of the project partners. Study results will be disseminated through publications, conference presentations, student education and advanced training of health professionals.Trial registration number NCT05149937.

Introduction Older people in need of home care are at risk of declining oral health as their visits to dentists are becoming less frequent due to restricted mobility. There is increasing evidence that poor oral health and systemic diseases are closely associated, for example, in cardiological, metabolic or neurodegenerative conditions. Thus, Interaction of Systemic Morbidity and Oral Health in Ambulatory Patients in Need of Home Care (InSEMaP) is investigating the need, provision and utilisation of oral healthcare, systemic morbidity and clinical status of the oral cavity in older people.Methods and analysis InSEMaP consists of four subprojects (SP), all involving the target population of older people in need of home care. In SP1 part a, a sample is surveyed using a self-report questionnaire. In SP1 part b, stakeholders (general practitioners, dentists, medical assistants, family and professional caregivers) are interviewed regarding barriers and facilitators using focus groups and personal interviews. In SP2, a retrospective cohort study, health insurance claims data are examined to investigate the utilisation of oral healthcare, its association with systemic morbidity and healthcare costs. In SP3, a clinical observational study will assess the oral health of participants by a dentist’s visit at home. SP4 synthesises the results of SP1, SP2 and SP3 to develop integrated clinical pathways, identifying strategies to uphold oral healthcare in older people. In assessing and evaluating the process of oral healthcare, and its associated systemic morbidity, InSEMaP aims to improve general healthcare across the sector boundary of dental and general practitioner care.Ethics and dissemination Ethics approval was obtained from the Institutional Review Board of the Hamburg Medical Chamber (approval number: 2021-100715-BO-ff). The results of this study will be disseminated through conference presentations and publications in peer-reviewed journals. An expert advisory board to support the InSEMaP study group will be established.Trial registration number German Clinical Trials Register: DRKS00027020.

Abstract Background In Germany, geriatricians deliver acute geriatric care during an acute hospital stay and subacute rehabilitation after transfer to a rehabilitation clinic. However, the proportion of patients who receive acute geriatric care (AGC) or are transferred to subacute rehabilitation (TSR) differs considerably between hospitals. The aim of this study was to analyse the association between the two geriatric treatment systems and care home admission or mortality in patients following hip fracture. Methods Health insurance claims data were used to identify the rate of AGC per hospital and the rate of TSR per hospital following hip fracture surgery in patients aged ≥ 80 years. Outcomes were cumulative admission to a care home and cumulative mortality within 6 months after hospital admission. Results Data from 23,046 hip fracture patients from 561 hospitals were analysed. The rate of AGC was not associated with care home admission. However, compared to high rates of AGC medium rates or no AGC were associated with increased death rates by 12% or 20%, respectively. Treatment in hospitals with low rates of TSR was associated with a 8% higher risk of care home admission and a 10% increased risk of death compared to treatment in hospitals with high rates of TSR. Conclusions Our study suggests potential effects of geriatric treatment: reduction of mortality in hospitals with high rates of AGC or reduction of care home admission and mortality in hospitals with high rates of TSR.

Abstract Background Fractures are a major health problem in aging societies. Preventive approaches combining bone health and fall prevention are rare. The osteoporotic fracture prevention program in rural areas (OFRA) is a health care fund-driven program for older people in randomly selected districts in Germany. The components of the program were falls prevention exercise classes, examination of bone health by a dual-energy X-ray absorptiometry (DXA) scan, and a consultation about “safety in the living environment.” The aim of this study was to evaluate this complex preventive intervention in a routine health care setting. Methods This cluster-randomized trial was performed from October 2015 to October 2018 and took place in 186 administrative districts in five federal states, 47 districts served as intervention districts, and 139, as controls. Within these districts, we included (a) all community-living women and men aged 70–85 years with prior fragility fractures and (b) all community-living women aged 75–80 years. The analysis used routine data collected by a health insurance company. The primary endpoint was all fragility fractures combined. Fracture types, mortality, and nursing home admission were explorative endpoints. Cox frailty models were used for comparative analyses with a median follow-up time of 365 days (interquartile range: 0 days). Results Nine thousand four hundred eight individuals were approached to participate in one of the program components, 27,318 individuals served as controls. The mean age was 78.7 years. Of those approached to participate, nearly 30% joined the exercise classes. DXA measurement was reimbursed for 13.6%, and 51.8% received advice about measures to increase “safety in the living environment.” The incidence of fragility fractures did not differ between the intervention and the control group (HR 0.94; 95% CI 0.80–1.11). However, femoral fractures, the most frequent fracture type, were reduced in the intervention group (HR 0.76; 95% CI 0.59–0.99). Mortality and nursing home admission did not differ between the intervention and the control group. Conclusions A comprehensive fracture prevention program for older people living in rural areas was implemented. The program did not affect the primary endpoint of all fragility fractures combined. It has to be considered that we used a modified intention to treat approach based on geographic randomization and information about endpoints relied exclusively on routine data of the health care insurance.

Abstract Background In the implementation of placement matching guidelines, feasibility has been concerned in previous research. Objectives of this process evaluation were to investigate whether the patient-centered matching guidelines (PCPM) are consistently applied in referral decision-making from an inpatient qualified withdrawal program to a level of care in aftercare, which factors affect whether patients actually receive matched aftercare according to PCPM, and whether its use is feasible and accepted by clinic staff. Methods The study was conducted as process evaluation within an exploratory randomized controlled trial in four German psychiatric clinics offering a 7-to-21 day qualified withdrawal program for patients suffering from alcohol dependence, and with measurements taken during detoxification treatment and six months after the initial assessment. PCPM were used with patients in the intervention group by feeding back to them a recommendation for a level of care in aftercare that had been calculated from Measurements in the Addictions for Triage and Evaluation (MATE) and discussed with the staff on the treatment unit. As measurements, The MATE, the Client Socio-Demographic and Service Receipt Inventory—European Version, a documentation form, the Control Preference Scale, and the Motivation for Treatment Scale were administered. A workshop for the staff at the participating trial sites was conducted after data collection was finished. Results Among 250 patients participating in the study, 165 were interviewed at follow-up, and 125 had received aftercare. Although consistency in the application of PCPM was moderate to substantial within the qualified withdrawal program (Cohen’s kappa ≥ .41), it was fair from discharge to follow-up. In multifactorial multinomial regression, the number of foregoing substance abuse treatments predicted whether patients received more likely undermatched (Odds Ratio=1.27; p=.018) or overmatched (Odds Ratio=0.78; p=.054) treatment. While the implementation process during the study was evaluated critically by the staff, they stated a potential of quality assurance, more transparency and patient-centeredness in the use of PCPM. Conclusions While the use of PCPM has the potential to enhance the quality of referral decision making within treatment, it may not be sufficient to determine referral decisions for aftercare.
