[Experience-based items of quality in psychiatric treatment: A first multivariate construct]

In the context of psychiatric care, user-generated measurement instruments may contribute to quality development and assurance. An explorative construct of experience-related quality components was developed in participative-collaborative cooperation that grasps the users' experiences of psychiatric care. After developing the components using a grounded theory methodology, they were quantified, and their interrelations were investigated using a multidimensional scaling method to explore their internal cohesion. The construct makes it possible to separate structural from interpersonal requirements of the quality components. It further indicated which components are more feasible for the home treatment setting, and which ones for an institutional setting. The components and the construct may be perceived as first steps towards the development of user-generated quality indicators; however, further validation steps are necessary.

Psychiatrization in mental health care: The emergency department

BACKGROUND

In the light of high incidences of diagnosed mental disorders and the growing utilization of mental healthcare services, a progressing psychiatrization of society has been hypothesized as the underlying dynamic of these developments. Mental healthcare institutions, such as psychiatric hospitals, may play a decisive role in this. However, there is a scarcity of research into how psychiatrization emerges in hospital settings. This paper explores whether the emergency department (ED) can be considered as a site where psychiatrization happens, becomes observable, and which factors in the context of the ED may be its potential drivers.

METHODS

Two cases as encountered in an interdisciplinary ED will be presented in the following in an anonymized way. Although the cases originate from individual consultations, they can be considered as prototypical. The cases were collected and discussed using the method of interactive interviewing. The results will be analyzed against the backdrop of current theoretic concepts of psychiatrization.

FINDINGS

The ED can be seen as an important area of contact between society and psychiatry. Decisions whether to label a certain condition as a "mental disorder" and to therefore initiate psychiatric treatment, or not, can be highly difficult, especially in cases where the (health) concerns are rather moderate, and clearly associated with common life problems. Psychiatrists' decisions may be largely influenced in favor of psychiatrization by a wide array of disciplinary, institutional, interpersonal, personal, cultural, and social factors.

CONCLUSIONS

The ED appears to be a promising field for research into the mechanisms and motives through which psychiatrization may emerge in mental healthcare settings. Psychiatrists in the ED work within a complex sphere of top-down and bottom-up drivers of psychiatrization. Encounters in the ED can be an important step toward adequate support for many individuals, but they also risk becoming the starting point of psychiatrization by interpreting certain problems through the psychiatric gaze, which may induce diagnoses of questionable validity and treatment of little use.

Needs and Experiences in Psychiatric Treatment (NEPT)- Piloting a Collaboratively Generated, Initial Research Tool to Evaluate Cross-Sectoral Mental Health Services

BACKGROUND

Research tools to evaluate institutions or interventions in the field of mental health have rarely been constructed by researchers with personal experience of using the mental health system ("experiential expertise"). This paper presents a preliminary tool that has been developed within a participatory-collaborative process evaluation as part of a controlled, multi-center, prospective cohort study (PsychCare) to evaluate psychiatric flexible and integrative treatment, FIT for short, models in Germany.

METHOD

The collaborative research team consisting of researchers with and without experiential expertise developed 12 experiential program components of FIT models by an iterative research process based on the Grounded Theory Methodology. These components were transformed into a preliminary research tool that was evaluated by a participatory expert panel, and during a pilot and validation study, the latter using a random sample of 327 users from 14 mental health departments. Internal consistency of the tool was tested using Cronbach's alpha. Construct validity was evaluated using a Principal Components Analysis (PCA) and a Jonckheere Terpstra test in relation to different implementation levels of the FIT model. Concurrent validity was tested against a German version of the Client Satisfaction Questionnaire (ZUF-8) using correlation analysis and a linear regression model.

RESULTS

The evaluation of the expert panel reduced 29 initial items to 16 that were further reduced to 11 items during the pilot study, resulting into a research tool (Needs and Experiences in Psychiatric Treatment-NEPT) that demonstrated good internal consistency (Cronbach's alpha of 0.89). PCA yielded a 1-component structure, which accounted for 49% of the total variance supporting the unidimensional structure of the tool. The total NEPT score increased alongside the increasing implementation of the FIT model (p < 0.05). There was evidence (p < 0.001) for convergent validity assessed against the ZUF-8 as criterion measure.

CONCLUSIONS

The NEPT tool seems to be promising for further development to assess the experiences with and fulfillment of needs of psychiatric care models from the perspective of users. This paper demonstrates that it is possible to use a participatory-collaborative approach within the methodologically rigorous confines of a prospective, controlled research design.

Designed to Clash? Reflecting on the Practical, Personal, and Structural Challenges of Collaborative Research in Psychiatry

Background: In the field of mental health research, collaborative and participatory approaches in which mental health service users actively contribute to academic knowledge production are gaining momentum. However, concrete examples in scientific literature that would detail how collaborative research projects are actually organized, and how they deal with the inherent challenges are rare. This paper provides an in-depth description of a three-year collaborative project that took place in the wider context of a mixed-method process evaluation of innovative models of psychiatric care in Germany. Methods: The in-depth description we provide here draws on a vast body of notes and records that originated from numerous meetings and sessions. The research group continuously and systematically reflected on their collaboration itself using the interpretative method of "interactive interviewing," which included that also the personal memories of the researchers were collectively re-discussed before and during the process of writing. Our concrete experiences as a group were then contextualized with and analyzed in the light of more general challenges that are central to collaborative research in general. Results: Performing collaborative research requires unconventional thinking and improvisation in order to find creative solutions for practical problems and to overcome the structural obstacles inherent to the process of academic knowledge production. An atmosphere of mutual trust and respect within the group is crucial, and continuous self-reflection or supervision can be largely beneficial. Challenges mainly originate from the vast heterogeneity that characterizes the researchers, usually including large differences in economic, cultural, and social capital. Conclusion: Collaborative research in the field of psychiatry is designed to bring together researchers with widely diverse backgrounds. Emerging conflicts are important parts of knowledge production but also exceptional opportunities to negotiate research ethics, and potential vehicles for personal growth and transformation. Success or failure of collaborative research largely depends on how divergences and conflicts are articulated, mediated, and reflected. This also holds true in the light of the power asymmetries within the research team and the structural power inherent to the engines of academic knowledge production.

Psychiatrization of Society: A Conceptual Framework and Call for Transdisciplinary Research

Purpose: Worldwide, there have been consistently high or even rising incidences of diagnosed mental disorders and increasing mental healthcare service utilization over the last decades, causing a growing burden for healthcare systems and societies. While more individuals than ever are being diagnosed and treated as mentally ill, psychiatric knowledge, and practices affect the lives of a rising number of people, gain importance in society as a whole and shape more and more areas of life. This process can be described as the progressing psychiatrization of society. Methods: This article is a conceptual paper, focusing on theoretical considerations and theory development. As a starting point for further research, we suggest a basic model of psychiatrization, taking into account its main sub-processes as well as its major top-down and bottom-up drivers. Results: Psychiatrization is highly complex, diverse, and global. It involves various protagonists and its effects are potentially harmful to individuals, to societies and to public healthcare. To better understand, prevent or manage its negative aspects, there is a need for transdisciplinary research, that empirically assesses causes, mechanisms, and effects of psychiatrization. Conclusion: Although psychiatrization has highly ambivalent effects, its relevance mainly derives from its risks: While individuals with minor disturbances of well-being might be subjected to overdiagnosis and overtreatment, psychiatrization could also result in undermining mental healthcare provision for the most severely ill by promoting the adaption of services to the needs and desires of the rather mild cases. On a societal level, psychiatrization might boost medical interventions which incite individual coping with social problems, instead of encouraging long-term political solutions.

Supported Employment, Participation at Work, and Peer Support: A Qualitative, Participatory Case Study Report of the Geesthacht Model

Background: For people who have experienced mental health crises or psychosocial disabilities, it is considerably more difficult to receive support to participate in work on an equal basis with others. In the town of Geesthacht, in Northern Germany, an integrative care network was implemented that allows for acute psychiatric treatment as well as participation in work and activities. This paper aims to explore the principles, advantages, and challenges of this innovative project. Methodology: Within the context of a participatory and collaborative process evaluation of a prospective controlled cohort study (PsychCare), researchers with and without experiential expertise conducted expert interviews and focus groups to evaluate the experiences of 37 employees, with and without lived experience, from various institutions associated with this care network. The data was analyzed using qualitative content analysis. Results: It was the change from financial compensation paid on a daily basis to a global treatment budget that allowed for a significant reduction of hospital beds in Geesthacht and freed up resources to implement a complex care network. Since then, various possibilities for participation, work, and activities for former service users, some of which are compensated financially, have been made available. These developments now allow for a less bureaucratic and often smooth transition from being a service user to involvement in participatory activities in the role of a peer, which is frequently perceived to be empowering and beneficial by participants with lived experience. At the same time, this care model has led to multiple role conflicts and different challenges for all parties involved. Conclusion: This innovative project in Geesthacht demonstrates the multifaceted potential of a global treatment budget system in the field of mental health care. To address certain downsides of the Geesthacht model, further development is necessary.

Disturbed time experience during and after psychosis

Disturbances in time experience have been argued to play a significant, if not causative role in the clinical presentation of schizophrenia. Phenomenological considerations suggest a fragmented or dis-articulated time experience causing both primary symptoms such as hallucinations, delusions, and self-disorders, as well as an intersubjective desynchronization. We employed content analysis on material collected from patients diagnosed with schizophrenia using the Time Questionnaire to generate hypotheses on possible disturbances of time experience in schizophrenia. As a key result we find evidence for the distinction between acute psychotic and post-psychotic syndromes. Acute psychosis is predominantly a disturbance of the passage of time, whereas the remission from psychosis is primarily defined by changes in the experience of the explicit structure of time integrating past, present, and future. We discuss our findings with regards to previous insights and observations on time experience and time perception. We suggest our findings hold significance for the diagnostic and therapeutic understanding of schizophrenia as well as for future integrative research on time experience in general.

Autonomy in Depressive Patients Undergoing DBS-Treatment: Informed Consent, Freedom of Will and DBS' Potential to Restore It

According to the World Health Organization, depression is one of the most common and most disabling psychiatric disorders, affecting at any given time approximately 325 million people worldwide. As there is strong evidence that depressive disorders are associated with a dynamic dysregulation of neural circuits involved in emotional processing, recently several attempts have been made to intervene directly in these circuits via deep brain stimulation (DBS) in patients with treatment-resistant major depressive disorder (MDD). Given the promising results of most of these studies, the rising medical interest in this new treatment correlates with a growing sensitivity to ethical questions. One of the most crucial concerns is that DBS might interfere with patients’ ability to make autonomous decisions. Thus, the goal of this article is to evaluate the impact DBS presumably has on the capacity to decide and act autonomously in patients with MDD in the light of the autonomy-undermining effects depression has itself. Following the chronological order of the procedure, special attention will first be paid to depression’s effects on patients’ capacity to make use of their free will in giving valid Informed Consent. We suggest that while the majority of patients with MDD appear capable of autonomous choices, as it is required for Informed Consent, they might still be unable to effectively act according to their own will whenever acting includes significant personal effort. In reducing disabling depressive symptoms like anhedonia and decrease of energy, DBS for treatment resistant MDD thus rather seems to be an opportunity to substantially increase autonomy than a threat to it.

Randomized controlled trial of the haemodynamic and recovery effects of xenon or propofol anaesthesia

BACKGROUND

There is limited clinical experience with xenon in a large number of patients. We present intra- and postoperative haemodynamic and recovery data comparing xenon and total intravenous anaesthesia with propofol.

METHODS

A total of 160 patients aged 18-60 years (ASA I and II) undergoing elective surgery took part in this prospective non-blinded randomized controlled trial. After local ethics committee approval and written informed consent, patients were allocated randomly to either the xenon or the propofol group. Anaesthesia was induced with propofol and remifentanil and was maintained with xenon at 60% (minimal alveolar concentration 0.95) or with propofol 0.1-0.12 mg kg(-1) min(-1). Remifentanil was titrated to clinical need in both groups.

RESULTS

The two study groups were comparable with respect to age, weight, height, gender and ASA classification. Baseline in heart rate and systolic arterial pressure (SAP) were comparable in both groups. Following induction, SAP initially decreased but returned to baseline values over 15 min in the xenon group and differed significantly from the propofol group. Heart rate decreased significantly only in the xenon group and remained at stable values. Occurrence and duration of hypertension, hypotension and bradycardia showed no significant difference between groups. Patient recovery time in the post-anaesthetic care unit and recovery from anaesthesia was similar in the two groups.

CONCLUSIONS

After induction the xenon/opioid regimen maintains systolic blood pressure at baseline levels and a low heart rate. No differences between groups were found in haemodynamic stability during anaesthesia. Recovery from xenon anaesthesia was similar to that observed in the propofol group.

High-dose chemotherapy in patients with breast cancer: evaluation of infusing peripheral blood stem cells containing occult tumor cells

The purpose of this study was to evaluate the frequency of detecting occult tumor cells in peripheral blood stem cell (PBSC) harvests and to determine the impact of infusing such cells on relapses after high-dose chemotherapy (HDC). Peripheral blood stem cell harvests from 223 patients with breast cancer were examined by an immunocytochemistry (ICC) method for detection of occult tumor cells, and infused after HDC without consideration of test results. Two hundred and four patients, 114 with stage II-III and 90 with stage IV disease who received only PBSC, that were tested by ICC were evaluated for time to relapse. Five hundred and eighty-one of 619 PBSC harvests (94%) from 223 patients were tested. Fifty-three of 581 harvests (9%), 8% from stage II-III and 10% from stage IV patients, were positive by ICC (P = 0.68). Forty-one of 223 patients (18%), 17/122 (14%) with stage II-III and 24/101 (24%) with stage IV disease, had positive harvests (P = 0.06). Eleven percent of patients who had 1-2 harvests tested were positive as compared to 32% of patients who had > or =3 PBSC harvests tested (P < 0.001). Nineteen patients who were infused with a mixture of ICC negative and untested PBSC harvests were excluded from analyses of relapse. The probabilities of relapse at 18 months for the 97 patients with stage II-III disease infused with ICC-negative and the 17 with ICC-positive PBSC were 0.19 and 0.13, respectively (P = 0.48). The probabilities of relapse at 18 months for patients achieving a CR or a CR in non-bone sites and improvement in bone lesions were 0.55 for the ICC-negative group (n = 30) and 0.45 for the ICC-positive group (n = 11) (P = 0.60). It was concluded that occult tumor cells were detected by ICC in PBSC harvests from a relatively small fraction of women with breast cancer, but were not associated with a significant increase in the probability of early relapse or progression when infused after HDC.

A randomized trial of two doses of cyclophosphamide with etoposide and G-CSF for mobilization of peripheral blood stem cells in 318 patients with stage II-III breast cancer

The purpose of this study was to develop a less toxic outpatient chemotherapy regimen for mobilizing peripheral blood stem cells (PBSC). Three hundred eighteen patients with newly diagnosed stage II-III breast cancer who had received conventional dose adjuvant chemotherapy were randomized to receive intermediate-dose cyclophosphamide (2 g/m2), etoposide (600 mg/m2), and granulocyte colony-stimulating factor (G-CSF) 6 micrograms/kg/day (ID-Cy, n = 162) or high-dose cyclophosphamide (4 g/m2) and the same doses of etoposide and G-CSF (HD-Cy, n = 156) followed by collection of PBSC. Three hundred seventeen of 318 patients had apheresis performed, and 315 received high-dose chemotherapy (HDC) followed by PBSC support. The median numbers of CD34+ cells collected in a median of two apheresis following ID-Cy and HD-Cy were 19.9 and 22.2 x 10(6)/kg, respectively (p = 0.04). The fractions of patients achieving CD34+ cell doses > or = 2.5 or > or = 5.0 x 10(6)/kg were not different between the two regimens. More patients receiving HD-Cy had grade 3-4 nausea (p = 0.001), vomiting (p = 0.03), and mucositis (p = 0.04). The fractions of patients having a neutrophil nadir < 0.5 x 10(9)/L following ID-Cy and HD-Cy were 0.83 and 0.95, respectively (p = < 0.001). The fractions of patients having a platelet nadir < 25 x 10(9)/L following ID-Cy and HD-Cy were 0.13 and 0.51, respectively (p = < 0.001). More patients in the HD-Cy group received platelet (p < 0.001) and red blood cell (p < 0.001) transfusions and were admitted to the hospital more frequently (p = 0.03) than patients receiving ID-Cy. Three hundred fifteen patients received HDC followed by infusion of PBSC. There were no significant differences in the incidence of transplant-related death or early survival between patients receiving ID-Cy or HD-Cy followed by HDC. It was concluded that a regimen of Cy 2 g/m2 with etoposide and G-CSF was effective for mobilization of PBSC with low morbidity and resource utilization in patients with limited prior chemotherapy exposure.

Collection of peripheral blood progenitor cells after the administration of cyclophosphamide, etoposide, and granulocyte-colony-stimulating factor: an analysis of 497 patients

BACKGROUND

There is great interpatient variability in the number of peripheral blood stem cells collected, as measured by CD34+ cell content, after the administration of chemotherapy and a growth factor. The ability to predict patients who fail to yield adequate quantities of CD34+ cells would be of value. However, very few reports include large numbers of patients treated in an identical fashion.

STUDY DESIGN AND METHODS

Between 1991 and 1995, 497 consecutive patients with a variety of malignant diseases received cyclophosphamide (4 g/m2), etoposide (600 mg/m2), and granulocyte-colony-stimulating factor (6 micrograms/kg/day) for mobilization and collection of a target dose > or = 2.5 x 10(8) CD34+ cells per kg. Multivariate analyses were performed to determine the factors associated with failure to achieve this target harvest.

RESULTS

A median of 14.71 x 10(6) CD34+ cells per kg (range, 0.08-137.55) was harvested with a median of 2 (range, 1-11) apheresis procedures. Ninety-one percent of patients yielded > or = 2.5 x 10(5) CD34+ cells per kg. Patients with Stage II-III breast cancer, who had pretreatment platelet counts > or = 150 x 10(9) per L and patients who underwent < or = 1 prior chemotherapy regimen had improved CD34+ cell yields. However, most patients with adverse risk factors yielded > or = 2.5 x 10(6) CD34+ cells per kg.

CONCLUSION

A regimen of cyclophosphamide, etoposide, and granulocyte-colony-stimulating factor led to the successful collection of adequate numbers of CD34+ cells in most patients without excessive toxicity. These observations confirm previous reports that intense prior therapy adversely affects the quantity of CD34+ cells harvested. Pretreatment and posttreatment variables did not predict with any certainty the small fraction of patients who fail to yield > or = 2.5 x 10(6) CD34+ cells per kg via multiple apheresis procedures.

Role of Na+/Ca2+ exchange and the plasma membrane Ca2+ pump in hormone-mediated Ca2+ efflux from pancreatic acini

The relative contributions of the Na+/Ca2+ exchange and the plasma membrane Ca2+ pump to active Ca2+ efflux from stimulated rat pancreatic acini were studied. Na+ gradients across the plasma membrane were manipulated by loading the cells with Na+ or suspending the cells in Na+-free media. The rates of Ca2+ efflux were estimated from measurements of [Ca2+]i using the Ca2+-sensitive fluorescent dye Fura 2 and 45Ca efflux. During the first 3 min of cell stimulation, the pattern of Ca2+ efflux is described by a single exponential function under control, Na+-loaded, and Na+-depleted conditions. Manipulation of Na+ gradients across the plasma membrane had minimal effects on resting [Ca2+]i, the rate constant of Ca2+ efflux, and [Ca2+]i levels attained by the cells after 5 min of stimulation. Changing Na+ gradients had no effect on the hormone-induced increase in [Ca2+]i. The results indicate that Ca2+ efflux from stimulated pancreatic acinar cells is mediated by the plasma membrane Ca2+ pump. The effects of several cations, which were used to substitute for Na+, on cellular activity were also studied. Choline+ and tetramethylammonium+ (TMA+) released Ca2+ from intracellular stores of pancreatic acinar, gastric parietal and peptic cells. These cations also stimulated enzyme and acid secretion from the cells. All effects of these cations were blocked by atropine. Measurements of cholecystokinin-octapeptide (CCK-OP)-stimulated amylase release from pancreatic acini, suspended in Na+, TMA+, choline+, or N-methyl-D-glucamine+ (NMG+) media containing atropine, were used to evaluate the effect of the cations on cellular function. NMG+, choline+, and TMA+ inhibited amylase release by 55, 40 and 14%, respectively. NMG+ also increased the Ca2+ permeability of the plasma membrane. Thus, to study Na+ dependency of cellular function, TMA+ is the preferred cation to substitute for Na+. The stimulatory effect of TMA+ can be blocked by atropine.
