Predicting patient outcomes in psychiatric hospitals with routine data: a machine learning approach.

BACKGROUND: A common problem in machine learning applications is availability of data at the point of decision making. The aim of the present study was to use routine data readily available at admission to predict aspects relevant to the organization of psychiatric hospital care. A further aim was to compare the results of a machine learning approach with those obtained through a traditional method and those obtained through a naive baseline classifier. METHODS: The study included consecutively discharged patients between 1st of January 2017 and 31st of December 2018 from nine psychiatric hospitals in Hesse, Germany. We compared the predictive performance achieved by stochastic gradient boosting (GBM) with multiple logistic regression and a naive baseline classifier. We tested the performance of our final models on unseen patients from another calendar year and from different hospitals. RESULTS: The study included 45,388 inpatient episodes. The models' performance, as measured by the area under the Receiver Operating Characteristic curve, varied strongly between the predicted outcomes, with relatively high performance in the prediction of coercive treatment (area under the curve: 0.83) and 1:1 observations (0.80) and relatively poor performance in the prediction of short length of stay (0.69) and non-response to treatment (0.65). The GBM performed slightly better than logistic regression. Both approaches were substantially better than a naive prediction based solely on basic diagnostic grouping. CONCLUSION: The present study has shown that administrative routine data can be used to predict aspects relevant to the organisation of psychiatric hospital care. Future research should investigate the predictive performance that is necessary to provide effective assistance in clinical practice for the benefit of both staff and patients.

Heaps of moles? - Mediating macroscopic and microscopic measurement of chemical substances.

In this paper I take a close look at the SI base quantity "amount of substance", and its unit, the mole. The mole was introduced as a base unit in the SI in 1971, and there is currently a proposal to change its definition. The current definition of the mole shows a certain ambiguity regarding the nature of the quantity "amount of substance". The proposed new definition removes the ambiguity, but at a cost: it becomes difficult to justify treating amount of substance as having its own dimension, and hence its own unit, the mole. I argue that the difficulties with amount of substance result from its role as a mediator between macroscopic and microscopic scales. To understand why amount of substance might have its own dimension, we need to connect amount of substance to mass, contra current proposals to separate them.

Why eliminativism?

A central thesis of Steven French's brand of ontic structural realism has always been his eliminativism about objects. Unsurprisingly, this bold and controversial thesis has seen a lot of critical discussion. In his book The Structure of the World-Metaphysics & Representation, French accordingly defends this thesis against a range of challenges. A novel feature of this defense is the use of dependence relations to articulate his eliminativism. In this paper I take a critical look at French's defense of eliminativism and argue that the dependence relations invoked do not eliminate objects.

Tooth loss in Sjögren's syndrome patients compared to age and gender matched controls.

BACKGROUND: To analyze the prevalence and location of tooth loss in Sjögren's syndrome (SS) patients and compare them with an age- and gender-matched control group. MATERIAL AND METHODS: Dental charts and x-rays of 108 (SS) patients were retrieved from an academic dental center and special care dentistry department. For each SS patient, an age- and gender-matched non-SS patient was randomly selected. Medication, number of extractions and date and location of extractions were assessed. Differences between SS and non-SS patients were analyzed using Mann-Whitney U tests, Chi-square tests and Fisher's exact tests. RESULTS: Significantly more SS patients were edentulous compared to the non-SS group (14.8% versus 1.9%, p = 0.001). SS patients had a 61% higher risk to have experienced one or more extractions than control patients. In the SS group, there was a non-significant tendency for more maxillary teeth to have been extracted than mandibular teeth (42:34). In the control group, the number of extractions in the maxilla and mandible were comparable (21:20). When divided into sextants, the number of SS patients with one or more extractions was significantly higher than for non-SS patients for each sextant (p = 0.001 to p = 0.032). The largest difference in the proportion of patients with one or more extractions between the SS and non-SS patients occurred in the upper anterior sextant (3.4 times more frequent). CONCLUSIONS: SS patients are more prone to experience dental extractions compared to patients without SS. It could be speculated that this is related to a decreased salivary secretion.

The Epidemiology, treatment, and complication of ameloblastoma in East-Indonesia: 6 years retrospective study.

BACKGROUND: Ameloblastoma is a neoplasm classified as a benign epithelial odontogenic tumor of the jaws, grow slowly and are locally invasive. The aim of the present study was to investigate the incidence, treatment, and complication of patients with ameloblastoma in East-Indonesia during six years retrospective study. MATERIAL AND METHODS: This retrospective study included 84 patients who were diagnosed with ameloblastoma from 2011 to 2016. There were 56 patients with treatment data available. Data from each patient, including gender, age, histologic type, the size of the tumor, radiologic form, tumor location, type of treatment, and complication were reviewed and analyzed retrospectively. RESULTS: Fourteen patients were diagnosed with unicystic ameloblastoma (25%), thirty two patients with multicystic follicular ameloblastoma (57%) and ten patients with an unspecified multicystic ameloblastoma (18%). A total of about 35 patients were treated conservatively (62.5%) and 21 patients were treated radically (37.5%). Swelling was present as a pre-operative complication in all 56 cases (100%). There were no complaints concerning speech. CONCLUSIONS: The majority findings of the histologic type were multicystic ameloblastoma and their location were in the mandible. Most ameloblastoma were treated conservatively and reconstructions were made with only titanium plates and not bone graft.

The KTx360°-study: a multicenter, multisectoral, multimodal, telemedicine-based follow-up care model to improve care and reduce health-care costs after kidney transplantation in children and adults.

BACKGROUND: Follow-up care after kidney transplantation is performed in transplant centers as well as in local nephrologist's practices in Germany. However, organized integrated care of these different sectors of the German health care system is missing. This organizational deficit as well as non-adherence of kidney recipients and longterm cardiovascular complications are major reasons for an impaired patient and graft survival. METHODS: The KTx360° study is supported by a grant from the Federal Joint Committee of the Federal Republic of Germany. The study will include 448 (39 children) incident patients of all ages with KTx after study start in May 2017 and 963 (83 children) prevalent patients with KTx between 2010 and 2016. The collaboration between transplant centers and nephrologists in private local practices will be supported by internet-based case-files and scheduled virtual visits (patient consultation via video conferencing). At specified points of the care process patients will receive cardiovascular and adherence assessments and respective interventions. Care will be coordinated by an additional case management. The goals of the study will be evaluated by an independent institute using claims data from the statutory health insurances and data collected from patients and their caregivers during study participation. To model longitudinal changes after transplantation and differences in changes and levels of immunosuppresive therapy after transplantation between study participants and historical data as well as data from control patients who do not participate in KTx360°, adjusted regression analyses, such as mixed models with repeated measures, will be used. Relevant confounders will be controlled in all analyses. DISCUSSION: The study aims to prolong patient and graft survival, to reduce avoidable hospitalizations, co-morbidities and health care costs, and to enhance quality of life of patients after kidney transplantation. TRIAL REGISTRATION: ISRCTN29416382 (retrospectively registered on 05.05.2017).

[Guideline-adherent inpatient psychiatric psychotherapeutic treatment of behavioral and psychological symptoms of dementia : Normative definition of personnel requirements]. / Leitliniengerechte stationäre psychiatrisch-psychotherapeutische Behandlung psychischer und Verhaltenssymptome bei Demenz : Normative Personalbedarfsermittlung.

BACKGROUND: Dementia is of increasing medical and societal relevance. Hospitalization of dementia patients is mostly due to behavioral and psychological symptoms of dementia (BPSD). There is a need for sufficient qualified personnel in hospitals in order to be able to effectively treat these symptoms. OBJECTIVES: This study aims at identifying the personnel requirements for guideline-conform, evidence-based inpatient treatment concepts for patients with BPSD and to compare these with the resources defined by the German psychiatric personnel regulations (Psych-PV). Furthermore, it was the aim to identify how often patients with dementia received non-pharmacological therapy during inpatient treatment. METHODS: Based on the current scientific evidence for treatment of BPSD, a schedule for a multimodal non-pharmacological treatment was defined and based on this the corresponding personnel requirements were calculated. Using the treatment indicators in psychiatry and psychosomatics (VIPP) database as a reference, it was calculated on what proportion of treatment days patients were classified into G1 according to the German Psych-PV and at least once received more than two treatment units per week. RESULTS: For the implementation of a guideline-oriented and evidence-based treatment plan, a higher need for personnel resources than that provided by the Psych-PV was detected in all areas. Currently patients with dementia who received at least more than two treatment units per week during inpatient hospitalization, were classified into G1 according to German Psych-PV on 17.9 % of treatment days. CONCLUSION: Despite evidence for the efficacy of non-pharmacological treatment measures on BPSD, these forms of treatment cannot be sufficiently provided under the current conditions. The realization of a new quality controlled therapeutic concept is necessary to enable optimized treatment of patients with BPSD.

[Guideline-adherent psychiatric psychotherapeutic treatment of bipolar disorders : Which resources are needed?] / Leitliniengerechte psychiatrisch-psychotherapeutische Behandlung bei bipolaren Störungen : Welche Ressourcen werden dafür benötigt?

In this article the guideline-adherent psychiatric psychotherapeutic treatment of patients with bipolar disorders is outlined and the required resources are estimated. Based on the core recommendations of the S3 guidelines for diagnostics and treatment of bipolar disorders published in 2012, inpatient treatment needs in hours per week and per patient are determined for both manic and bipolar depressive episodes. The resulting staffing requirements are estimated on this basis. In summary, for guideline-adherent inpatient psychiatric psychotherapeutic treatment the additional needs regarding the physician/psychotherapeutic domain add up to 44 min per patient and week during a manic episode and 88 min for patients with bipolar depression when compared to current psychiatry staffing regulations.

Evolutionary implications of mitochondrial genetic variation: mitochondrial genetic effects on OXPHOS respiration and mitochondrial quantity change with age and sex in fruit flies.

The ancient acquisition of the mitochondrion into the ancestor of modern-day eukaryotes is thought to have been pivotal in facilitating the evolution of complex life. Mitochondria retain their own diminutive genome, with mitochondrial genes encoding core subunits involved in oxidative phosphorylation. Traditionally, it was assumed that there was little scope for genetic variation to accumulate and be maintained within the mitochondrial genome. However, in the past decade, mitochondrial genetic variation has been routinely tied to the expression of life-history traits such as fertility, development and longevity. To examine whether these broad-scale effects on life-history trait expression might ultimately find their root in mitochondrially mediated effects on core bioenergetic function, we measured the effects of genetic variation across twelve different mitochondrial haplotypes on respiratory capacity and mitochondrial quantity in the fruit fly, Drosophila melanogaster. We used strains of flies that differed only in their mitochondrial haplotype, and tested each sex separately at two different adult ages. Mitochondrial haplotypes affected both respiratory capacity and mitochondrial quantity. However, these effects were highly context-dependent, with the genetic effects contingent on both the sex and the age of the flies. These sex- and age-specific genetic effects are likely to resonate across the entire organismal life-history, providing insights into how mitochondrial genetic variation may contribute to sex-specific trajectories of life-history evolution.

[Normative definition of staff requirement for a guideline-adherent inpatient qualified detoxification treatment in alcohol dependence]. / Personalbedarfsermittlung für eine leitliniengerechte stationäre Qualifizierte Entzugsbehandlung bei Alkoholabhängigkeit.

The central element of the "qualified withdrawal treatment" of alcohol dependence is - in addition to physical withdrawal treatment - psychotherapy. The treatment of the underlying addictive disorder that is displayed by intoxication, harmful behaviour and withdrawal symptoms is only possible with a combination of somatic and psychotherapeutic treatment elements. The successfully established multimodal therapy of the "qualified alcohol withdrawal treatment", postulated in the current S3-Treatment Guidelines, requires a multi-disciplinary treatment team with psychotherapeutic competence. The aim of the present work is to calculate the normative staff requirement of a guideline-based 21-day qualified withdrawal treatment and to compare the result with the staffing regulations of the German Institute for Hospital Reimbursement. The present data support the hypothesis that even in the case of a hundred per cent implementation of these data, adequate therapy of alcohol-related disorders, according to the guidelines, is not feasible. This has to be considered when further developing the finance compensation system based on the described superseded elements of the German Institute for Hospital Reimbursement.

[Guideline-conform inpatient psychiatric psychotherapeutic treatment of chronic depression: Normative personnel requirements]. / Leitlinienentsprechende stationäre psychiatrisch-psychotherapeutische Behandlung der chronischen Depression : Normative Personalbedarfsermittlung.

BACKGROUND: Chronic depression is a frequent mental disorder representing a significant subjective and economic burden. Effective disorder-specific treatment of chronic depression presupposes sufficient funding of treatment resources. OBJECTIVE: Definition of normative needs of personnel resources for guideline-compliant and evidence-based inpatient treatment of chronic depression based on treatment duration and intensity. The personnel resources determined were compared to the resources provided on the basis of the existing reimbursement system (Psych-PV) in Germany. MATERIAL AND METHODS: Resources determined according to national treatment guidelines and empirical evidence were compared to personnel resources dictated by the German Psych-PV reimbursement algorithm. RESULTS: The current funding algorithm greatly underestimates the resources needed for a guideline-compliant and evidence-based treatment program, even if healthcare providers received 100 % reimbursement of the sum determined by the Psych-PV algorithm. DISCUSSION: The results clearly show that even in the case of a full coverage of the current German reimbursement algorithm, funding allocation for evidence-based inpatient treatment of chronic depression is insufficient. In addition, the difficulties of specific coding of chronic depression in the ICD-10 system generates a major problem in the attempt to measure the current resources needed for sufficient treatment.

[Guideline-conform psychiatric psychotherapeutic treatment for patients with schizophrenia : A normative evaluation of necessary personnel requirements]. / Leitlinienkonforme psychiatrisch-psychotherapeutische Behandlung für Patienten mit Schizophrenie : Eine normative Berechnung des benötigten Personalbedarfs.

BACKGROUND: Although national treatment guidelines and current publications of the German Federal Joint Committee (Gemeinsamer Bundesausschuss) recommend cognitive behavior therapy for all patients with schizophrenia, the implementation of these recommendations in current inpatient and outpatient treatment is only rudimentary. OBJECTIVES: The aim of this study was to systematically search randomized controlled studies (RCTs), meta-analyses and the guidelines of the German Association for Psychiatry and Psychotherapy, Psychosomatics and Neurology (DGPPN) and the British National Institute for Health and Clinical Excellence (NICE) in order to assess the number of personnel necessary for psychiatric and therapeutic inpatient treatment in line with present guidelines. Moreover, the number of staff required was compared with the personnel resources designated by the German psychiatry personnel regulations (Psych-PV). METHODS: The German and NICE guidelines, RCTs and meta-analyses were analyzed and an adequate weekly treatment plan for an inpatient unit was developed. Moreover, the number of personnel necessary to realize the treatment plan was calculated. RESULTS: In order to realize adequate inpatient treatment approximately 107 min extra for medical psychotherapeutic personnel per patient and week (of which 72 min for psychotherapy) and another 60 min for nursing staff per patient and week are required in addition to the current Psych-PV regulations. Thus, implementation in an open ward with 20 inpatients would require 3.62 positions for physicians, 0.7 positions in psychology and 12.85 positions for nursing staff (including management positions and night shifts). DISCUSSION: These evidence-based recommendations for precise specifications of inpatient treatment should lead to improved inpatient treatment in line with present guidelines. Moreover, outpatients and day patients could be included in this treatment model. The results should be considered in the construction of the future prospective payment system for inpatient psychiatric healthcare in Germany.

[Guideline-adherent inpatient psychiatric psychotherapeutic treatment of obsessive-compulsive disorder : Normative definition of personnel requirements]. / Leitliniengerechte stationäre psychiatrisch-psychotherapeutische Behandlung der Zwangsstörung : Normative Personalbedarfsermittlung.

BACKGROUND: Guideline-oriented inpatient psychiatric and psychotherapeutic treatment of patients with obsessive-compulsive disorder (OCD) is an important part of the care available for these patients. It may not be adequately reflected in the current personnel resources available according to the German psychiatry personnel regulation (Psych-PV). OBJECTIVES: The goal of this work was to assess the personnel resources necessary for a guideline-oriented inpatient psychiatric and psychotherapeutic treatment of patients with OCD and compare the necessary resources with the resources available according to Psych-PV. METHODS: Based on the German national guidelines for OCD and a meta-analysis on treatment intensity, we formulated a normative weekly treatment plan. Based on this plan we calculated the necessary personnel resources and compared these with the resources available according to Psych-PV category A1 (standard care). RESULTS: The weekly treatment time for a guideline-oriented inpatient psychiatric and psychotherapeutic treatment of patients with OCD is 23.5 h per week. This corresponds to a weekly personnel requirement of 20.9 h. This requirement is only partly reflected in the Psych-PV (17.3 h, 82.8 %). The coverage of personnel resources by Psych-PV is even lower for psychotherapy provided by psychiatrist and psychologists (38.3 %, i. e. 183 min in the normative plan versus 70 min in Psych-PV). CONCLUSIONS: The current paper shows that the personal resources required for a guideline-oriented inpatient psychiatric and psychotherapeutic treatment of patients with OCD is not adequately reflected in the German psychiatry personnel regulation (Psych-PV). The actual shortage may be underestimated in our paper.

[Guideline-oriented inpatient psychiatric psychotherapeutic/psychosomatic treatment of anxiety disorders : How many personnel are need?]. / Leitliniengerechte stationäre psychiatrisch-psychotherapeutische/psychosomatische Behandlung von Angsterkrankungen : Wieviel Personal ist erforderlich?

BACKGROUND/OBJECTIVES: The reimbursement of inpatient psychiatric psychotherapeutic/psychosomatic hospital treatment in Germany is regulated by the German personnel ordinance for psychiatric hospitals (Psych-PV), which has remained unchanged since 1991. The aim of this article was to estimate the personnel requirements for guideline-adherent psychiatric psychotherapeutic hospital treatment. METHODS: A normative concept for the required psychotherapeutic "dose" for anxiety disorders was determined based on a literature review. The required staffing contingent was compared to the resources provided by the Psych-PV based on category A1. RESULTS: According to the German policy guidelines for outpatient psychotherapy, a quota of 25 sessions of 50 min each (as a rule plus 5 probatory sessions) is reimbursed. This approach is supported by studies on dose-response relationships. As patients undergoing inpatient treatment for anxiety disorders are usually more severely ill than outpatients, a contingent of 30 sessions for the average treatment duration of 5 weeks seems appropriate in order to fully exploit the costly inpatient treatment time (300 min per patient and week). In contrast, only 70 min are reimbursed according to the Psych-PV. The total personnel requirement for the normative concept is 624 min per patient and week. The Psych-PV only covers 488 min (78 %). CONCLUSION: Currently, the time contingents for evidence-based psychiatric psychotherapeutic/psychosomatic hospital care are nowhere near sufficient. In the development of future reimbursement systems this needs to be corrected.

Outcome in Men with a Screen-detected Abdominal Aortic Aneurysm Who are not Fit for Intervention.

OBJECTIVE/BACKGROUND: Abdominal aortic aneurysm (AAA) screening in Gloucestershire has been ongoing for 25 years. The aim of this study was to review the outcome of a cohort of men with a large (> 5.4 cm) screen-detected AAA who did not have early intervention for their AAA. METHODS: A prospectively maintained database was interrogated for a 10-year interval from 2001 to 2011. Men who did not have their large AAA repaired within 3 months of the diagnosis were identified. The reasons for initial nonintervention and subsequent outcomes were identified from a combination of hospital case notes and general practitioner records. RESULTS: Of 334 men referred, 59 (median age 71 years, range 62-83 years) did not have intervention within 3 months (initial nonintervention rate 17.6%). The reasons included placed back on surveillance after assessment (n = 34); immediately discharged (n = 12); required further investigations (n = 5); died before complete assessment (n = 3); and incomplete follow-up (n = 5). Sixteen men had delayed AAA repair with no perioperative mortality. Overall mortality in the study was 14/34 (nine from ruptured AAA, the rest from medical conditions). Two further men survived repair of a ruptured AAA. The overall rate of ruptured AAA was 11/59 (18.6%). CONCLUSION: Information from studies such as these can be used to help plan treatment of men with a large AAA and to compare performance of vascular units.

[Where is convergence of psychiatry budgets leading to? A comparison of staffing regulations and actual personnel resources]. / Wohin führt die Konvergenz der Psychiatriebudgets? Ein Vergleich von Psych-PV-Vorgaben und tatsächlichen Personalressourcen.

BACKGROUND: Staffing regulations have determined the number of qualified staff required for sufficient, appropriate and economical inpatient mental health care in Germany since 1991. This minimum level of structural quality will probably be abolished in the context of the convergence of hospital budgets starting in 2019. AIMS AND OBJECTIVES: The aim of this study was to analyze the current fulfilment of staffing regulations in terms of time per patient in a large nationwide sample. MATERIAL AND METHODS: The required minutes of staff time as defined by staffing regulations were calculated for each patient using the treatment classifications provided by a large nationwide database. The actual use of staff time was calculated on the basis of average costs published by the German Institute for Hospital Reimbursement. Both figures were compared to calculate the fulfilment of staffing regulations. RESULTS: The study included approximately 95,000 inpatient episodes from 46 psychiatric hospitals and departments with a total length of stay of almost 2.5 million days. On average, the weekly use of staff resources per patient was 190 min (10 %) below the requirements of the staffing regulations. The largest gap in absolute terms was found in nursing staff where the weekly time per patient was 189 min (14 %) below the requirements of the staffing regulations. CONCLUSION: The convergence of psychiatric hospital budgets starts in 2019 below a level of funding required to fulfil staffing regulations. This would perpetuate inadequately funded structures and should initially be opposed with a demand for complete fulfilment of staffing regulations. Thereafter, a normative consent should be reached to define the resources required for current inpatient mental health care.

[Guideline-adherent psychiatric-psychotherapeutic hospital care: Normative definition of staff required using the example of depression]. / Leitliniengerechte psychiatrisch-psychotherapeutische Krankenhausbehandlung : Normative Personalermittlung am Beispiel Depression.

BACKGROUND: Unipolar depression is of high relevance in German inpatient treatment. An effective psychiatric psychotherapeutic hospital treatment also requires sufficient staff for carrying out psychotherapeutic treatment. AIMS AND OBJECTIVES: The aim of this study was to define the staff requirements for guideline-adherent psychiatric-psychotherapeutic inpatient treatment of depression on the basis of a weekly treatment schedule for a 5-week admission period. A further aim was to compare the staff required with the resources defined by the German psychiatric staffing regulations (Psych-PV). MATERIAL AND METHODS: The weekly schedule was normatively defined on the basis of the current evidence for treatment efficacy and effectiveness. The staff required was calculated on the basis of the weekly schedule. The time for psychotherapy defined by the Psych-PV was calculated using the treatment classification provided by a large nationwide database. RESULTS: Regarding psychotherapy, 280 min per week is regarded as necessary and usually sufficient according to the current evidence. The results showed clearly higher requirements of working time of psychiatrists and psychologists than those defined by the Psych-PV. In particular, the Psych-PV allows only 72 min for psychotherapy per patient and week and only a limited amount of direct patient contact with psychiatrists. CONCLUSION: The figures provided impressively show that the Psych-PV does not allow effective guideline-adherent hospital treatment within a reasonable length of hospital stay. Despite its evidential effectiveness, psychotherapeutic treatment cannot be sufficiently provided under the current financing circumstances.

[Resource use and financing of guideline-adherent psychotherapeutic inpatient care]. / Aufwand und Finanzierung leitliniengerechter, psychotherapeutischer Behandlung im Krankenhaus.

BACKGROUND: The financing of psychiatric psychotherapeutic care in Germany is determined by the German psychiatric staffing regulations which are unchanged since 1991. Psychotherapy was established after 1991 as an effective and indispensable treatment of mental and behavioral disorders. AIMS AND OBJECTIVES: The aim of this study was to empirically investigate the use of psychiatrists' and psychologists' working time for psychotherapy in guideline-adherent hospital care. A further aim was to compare these results to the resources defined by the German psychiatric staffing regulations and in the new prospective payment system for psychiatry and psychosomatics in Germany. MATERIAL AND METHODS: University hospitals for psychiatry and psychotherapy were asked to retrospectively provide data of patients for which guideline-adherent care was possible. Participating institutions provided both data describing the staff time utilization of psychotherapeutic services provided by psychiatrists and psychologists and patient classifications according to the German psychiatric staffing regulations and the new prospective payment system for psychiatry and psychosomatics. RESULTS: Resources defined by the German psychiatric staffing regulations covered a mean of only 71 min of psychotherapy per patient and week while the actual mean intensity of psychotherapeutic care provided by the participating hospitals was 194 min per patient and week. The associated use of staff time was 102 min per patient and week. Both figures increased during an inpatient episode. The resources defined by the German psychiatric staffing regulations covered only 70 % of medical and psychological personnel. The current configuration of the new prospective payment system for psychiatry and psychosomatics covered only 59 % of staff time. CONCLUSION: The results of this study provide another unambiguous recommendation to adjust the out-dated German psychiatric staffing regulations to the current evidence and S3 guidelines for psychiatric psychotherapeutic hospital care. In particular, more resources are required for the provision of psychotherapeutic care.
