Recovery opportunities, work-home conflict, and emotional exhaustion among hematologists and oncologists in private practice.

Hematologists and oncologists in private practice play a central role in the care provided for cancer patients. The present study analyzes stress and relaxation aspects in the work of hematologists and oncologists in private practice in Germany in relation to emotional exhaustion, as a core dimension of burnout syndrome. The study focuses on the opportunities for internal recovery using breaks and time out during the working day, the frequency of working on weekends and on vacation, and the physician's work-home and home-work conflict. Postulated associations between the constructs were analyzed using a structural equation model. If work leads to conflicts in private life (work-home conflict), it is associated with greater emotional exhaustion. Working frequently at the weekend is associated with greater work-home conflict and indirectly with greater emotional exhaustion. By contrast, the availability of opportunities to relax and recover during the working day is associated with less work-home conflict and indirectly with less emotional exhaustion. These results underline the importance of internal recovery opportunities during the working day and a successful interplay between working and private life for the health of outpatient hematologists and oncologists.

Patients' Trust in Physician, Patient Enablement, and Health-Related Quality of Life During Colon Cancer Treatment.

In cancer care, where patients and their families experience significant emotional distress and patients have to deal with complex medical information, patient centeredness is an important aspect of quality of care. The aim of this study is to examine the impact of patients' trust in their oncologists and patients' enablement on changes in health-related quality of life of colon cancer patients during follow-up care. We conducted a prospective study in a representative sample of private practices of German oncologists (N = 44). Patients (N = 131) filled out a standardized questionnaire prior to their first consultation (T0), directly after the first consultation (T1) and after two months (T2). Data were analyzed by structural equation modeling. Significant associations were found between trust in physician and changes in physical functioning between T1 and T2, and between trust in physician and patient enablement. Patient enablement is significantly associated with changes in physical functioning between T1 and T2. The results underline the importance of building a close and trustful patient-physician relationship in the oncology encounter. A central mechanism of the association between the quality of the relationship and health outcomes seems to be patient enablement. To enable patients to cope with their situation by making them understand their diagnosis, treatments, and side effects can impact health-related quality of life in physical domains.

Biological Relevance and Therapeutic Potential of the Hypusine Modification System.

Hypusine modification of the eukaryotic initiation factor 5A (eIF-5A) is emerging as a crucial regulator in cancer, infections, and inflammation. Although its contribution in translational regulation of proline repeat-rich proteins has been sufficiently demonstrated, its biological role in higher eukaryotes remains poorly understood. To establish the hypusine modification system as a novel platform for therapeutic strategies, we aimed to investigate its functional relevance in mammals by generating and using a range of new knock-out mouse models for the hypusine-modifying enzymes deoxyhypusine synthase and deoxyhypusine hydroxylase as well as for the cancer-related isoform eIF-5A2. We discovered that homozygous depletion of deoxyhypusine synthase and/or deoxyhypusine hydroxylase causes lethality in adult mice with different penetrance compared with haploinsufficiency. Network-based bioinformatic analysis of proline repeat-rich proteins, which are putative eIF-5A targets, revealed that these proteins are organized in highly connected protein-protein interaction networks. Hypusine-dependent translational control of essential proteins (hubs) and protein complexes inside these networks might explain the lethal phenotype observed after deletion of hypusine-modifying enzymes. Remarkably, our results also demonstrate that the cancer-associated isoform eIF-5A2 is dispensable for normal development and viability. Together, our results provide the first genetic evidence that the hypusine modification in eIF-5A is crucial for homeostasis in mammals. Moreover, these findings highlight functional diversity of the hypusine system compared with lower eukaryotes and indicate eIF-5A2 as a valuable and safe target for therapeutic intervention in cancer.

Deficiency of the miR-29a/b-1 cluster leads to ataxic features and cerebellar alterations in mice.

miR-29 is expressed strongly in the brain and alterations in expression have been linked to several neurological disorders. To further explore the function of this miRNA in the brain, we generated miR-29a/b-1 knockout animals. Knockout mice develop a progressive disorder characterized by locomotor impairment and ataxia. The different members of the miR-29 family are strongly expressed in neurons of the olfactory bulb, the hippocampus and in the Purkinje cells of the cerebellum. Morphological analysis showed that Purkinje cells are smaller and display less dendritic arborisation compared to their wildtype littermates. In addition, a decreased number of parallel fibers form synapses on the Purkinje cells. We identified several mRNAs significantly up-regulated in the absence of the miR-29a/b-1 cluster. At the protein level, however, the voltage-gated potassium channel Kcnc3 (Kv3.3) was significantly up-regulated in the cerebella of the miR-29a/b knockout mice. Dysregulation of KCNC3 expression may contribute to the ataxic phenotype.

The initial clinical interview--can it reduce cancer patients' fear?

PURPOSE: A common phenomenon among cancer patients is a fear of cancer recurrence or cancer progression (FOP). The aim of the present study was to analyze whether the oncologist is able to reduce patients' FOP at the initial clinical interview. METHOD: A prospective, longitudinal study included patients who were consulting private-practice oncologists in Germany for the first time. Recruitment was carried out by 44 members of the Professional Organization of Office-Based Hematologists and Oncologists. In the patient surveys, data on colon cancer patients' perceptions of communications with their oncologist and on patient-reported outcomes were collected over a period of 6 months. The present study analyzed the patients' data before their first consultation (T 0) and within 3 days after the first consultation (T 1). RESULTS: A total of 169 patients agreed to participate in the study. Backwards multiple regression analysis was conducted to determine whether the change (T 0-T 1) in FOP is associated with demographic, medical, or psychosocial determinants, or with the physician-patient communication. A significant association was found between the change in FOP and interruptions to the conversation, the comprehensibility of the information provided, the extent of perceived empathy from the physician, and the patient's social support and family status. CONCLUSION: Private social support and the initial medical encounter can help reduce FOP. Particularly, oncologists should ensure that they facilitate the presentation of information in a comprehensible way while avoiding interruptions and that they take particular care of patients with poor social support.

Determinants of physician empathy during medical education: hypothetical conclusions from an exploratory qualitative survey of practicing physicians.

BACKGROUND: Empathy is an outcome-relevant physician characteristic and thus a crucial component of high-quality communication in health care. However, the factors that promote and inhibit the development of empathy during medical education have not been extensively researched. Also, currently there is no explicit research on the perspective of practicing physicians on the subject. Therefore the aim of our study was to explore physicians' views of the positive and negative influences on the development of empathy during their medical education, as well as in their everyday work as physicians. METHOD: We administered a written Qualitative Short Survey to 63 physicians in seven specialties. They were able to respond anonymously. Our open-ended question was: "What educational content in the course of your studies and/or your specialist training had a positive or negative effect on your empathy?" We analyzed the data using thematic content analysis following Mayring's approach. RESULTS: Forty-two physicians took part in our survey. All together, they mentioned 68 specific factors (37 positive, 29 negative, 2 neutral) from which six themes emerged: 1. In general, medical education does not promote the development of empathy. 2. Recognizing the psycho-social dimensions of care fosters empathy. 3. Interactions with patients in medical practice promote empathy. 4. Physicians' active self-development through reflective practice helps the development of empathy. 5. Interactions with colleagues can both promote and inhibit empathy through their role modeling of empathic and non-empathic behavior. 6. Stress, time pressure, and adverse working conditions are detrimental to empathy development. CONCLUSIONS: Our results provide an overview of what might influence the development of clinical empathy, as well as hypothetical conclusions about how to promote it. Reflective practice seems to be lacking in current medical curricula and could be incorporated. Raising physicians' awareness of the psycho-social dimension of disease, and of the impact of peer influence and role modeling, seems promising in this regard, too. Stress and well-being seem to be closely related to physician empathy, and their modulation must take into account individual, social, and organizational factors. Further research should investigate whether or how these hypothetical conclusions can deepen our understanding of the determinants of physician empathy in order to help its promotion.

BSE-associated prion-amyloid cardiomyopathy in primates.

Prion amyloidosis occurred in the heart of 1 of 3 macaques intraperitoneally inoculated with bovine spongiform encephalopathy prions. This macaque had a remarkably long duration of disease and signs of cardiac distress. Variant Creutzfeldt-Jakob disease, caused by transmission of bovine spongiform encephalopathy to humans, may manifest with cardiac symptoms from prion-amyloid cardiomyopathy.

Protease-sensitive prion species in neoplastic spleens of prion-infected mice with uncoupling of PrP(Sc) and prion infectivity.

Prion diseases are fatal neurodegenerative disorders. An important step in disease pathophysiology is the conversion of cellular prion protein (PrP(C)) to disease-associated misfolded conformers (PrP(Sc)). These misfolded PrP variants are a common component of prion infectivity and are detectable in diseased brain and lymphoreticular organs such as spleen. In the latter, PrP(Sc) is thought to replicate mainly in follicular dendritic cells within spleen follicles. Although the presence of PrP(Sc) is a hallmark for prion disease and serves as a main diagnostic criterion, in certain instances the amount of PrP(Sc) does not correlate well with neurotoxicity or prion infectivity. Therefore, it has been proposed that prions might be a mixture of different conformers and aggregates with differing properties. This study investigated the impact of disruption of spleen architecture by neoplasia on the abundance of different PrP species in spleens of prion-infected mice. Although follicular integrity was completely disturbed, titres of prion infectivity in neoplastic spleens were not significantly altered, yet no protease-resistant PrP(Sc) was detectable. Instead, unique protease-sensitive prion species could be detected in neoplastic spleens. These results indicate the dissociation of PrP(Sc) and prion infectivity and showed the presence of non-PrP(Sc) PrP species in spleen with divergent biochemical properties that become apparent after tissue architecture disruption.

Patient satisfaction in inpatient psychiatric treatment compared with inpatient equivalent home treatment in Germany: an in-depth qualitative study.

Background: Inpatient treatment (IT) is the predominant form of psychiatric care in Germany and worldwide, whereby forms of psychiatric treatment have mainly evolved in the direction of home services. Inpatient equivalent home treatment (IEHT) is a new and additional pillar of psychiatric acute care provision legally embedded since 2018 in Germany. Objective: The aim of this study was to conduct an in-depth exploration as little qualitative research has been performed so far in Germany to examine possible differences in patient satisfaction with IT compared with IEHT. Methods: In the current qualitative study, N = 9 patients of a German hospital providing IT and IEHT were interviewed with the problem-centered interview. Inclusion criteria were IT or IT with subsequent IEHT. The theoretical sampling method was applied to select test persons in the research process. The experiences of the participants during their psychiatric treatment were analyzed using a qualitative content analysis. Results: The results of both types of psychiatric treatment refer to different satisfaction factors during the treatment period. The function of fellow patients, the setting of the treatment, the conditions in place, and the relationship to relatives turn out to be pivotal for patient satisfaction. In addition, the quality of the therapy and relationship to caregivers itself can have an impact on patient satisfaction, particularly by shared decision making. During the IEHT, patient satisfaction can be strengthened by the possibility to handle daily tasks, to be close to relatives, while not so close to fellow patients, whereas IT patients are mostly satisfied because of the distance to their everyday life and the closeness to fellow patients. The choice of the form of psychiatric treatment according to the individual needs of the patients seems to be one key driver that can in turn increase patient satisfaction. In addition, a clean and hygienic environment seems to be critical for our respondents as a lack of it is one of the reasons to drop out of treatment. Conclusions: Despite its limitations, this hypothesis-generating study is one of the first investigating German IEHT in comparison with IT in an in-depth qualitative approach contributing to a patient-oriented and cost-effective psychiatric treatment. Although hospitals are highly complex organizations and therefore not directly comparable, other German and international providers of IEHT may derive several generic success factors from this study for the development and improvement of patient satisfaction.

Persistent retroviral infection with MoMuLV influences neuropathological signature and phenotype of prion disease.

A fundamental step in pathophysiology of prion diseases is the conversion of the host encoded prion protein (PrP(C)) into a misfolded isoform (PrP(Sc)) that accumulates mainly in neuronal but also non-neuronal tissues. Prion diseases are transmissible within and between species. In a subset of prion diseases, peripheral prion uptake and subsequent transport to the central nervous system are key to disease initiation. The involvement of retroviruses in this process has been postulated based on the findings that retroviral infections enhance the spread of prion infectivity and PrP(Sc) from cell to cell in vitro. To study whether retroviral infection influences the phenotype of prion disease or the spread of prion infectivity and PrP(Sc) in vivo, we developed a murine model with persistent Moloney murine leukemia retrovirus (MoMuLV) infection with and without additional prion infection. We investigated the pathophysiology of prion disease in MoMuLV and prion-infected mice, monitoring temporal kinetics of PrP(Sc) spread and prion infectivity, as well as clinical presentation. Unexpectedly, infection of MoMuLV challenged mice with prions did not change incubation time to clinical prion disease. However, clinical presentation of prion disease was altered in mice infected with both pathogens. This was paralleled by remarkably enhanced astrogliosis and pathognomonic astrocyte morphology in the brain of these mice. Therefore, we conclude that persistent viral infection might act as a disease modifier in prion disease.

A longitudinal study of changes in provider-patient interaction in treatment of localized prostate cancer.

PURPOSE: Whilst much is known as to the met and unmet communication needs of prostate cancer patients, few studies have been conducted on the changes in communication between provider and patient over time. Therefore, the aim of our study is to examine (a) whether there are changes over time in the quality of psychosocial care in long-term treatment of localized prostate cancer and (b) whether those changes are associated with the treatment decision. METHODS: HAROW is a prospective, observational study designed to collect clinical data and patient reported outcomes (PROs) of different treatment options (hormonal therapy, active surveillance, radiation, operation, watchful waiting) for newly diagnosed patients with localized prostate cancer under real conditions. At 6-month intervals, general clinical data, PROs (e.g. quality of life, quality of physician-patient interaction) and individual costs are documented. We analysed data of N = 1,216 patients at the time of initial diagnosis (T1) and after 6 months (T2). RESULTS: There is a significant decline in shared decision-making behaviour of physicians for the group of patients undergoing a prostatectomy and for the hormonal therapy group at the time of initial diagnosis and after 6 months. In terms of emotional support by physicians, there is a significant difference between the treatment groups at the time of initial diagnosis with patients undergoing a prostatectomy reporting significantly less support than the hormonal therapy group. CONCLUSION: Future research from both, the providers' and the patients' perspective, will have to clarify if we can interpret our results as change in the communication behaviour once the treatment decision for prostatectomy or hormonal therapy is made.

Why context matters when changing the diet: A narrative review of placebo, nocebo, and psychosocial context effects and implications for outcome research and nutrition counselling.

Placebo (PE) and nocebo effects (NE) have been subjects of systematic research in medicine and psychotherapy for many decades to distinguish between the (specific) pharmacological effect of medication and the (unspecific) effect of the context. Despite this significant research, the awareness, operationalisation, and reflection of the multiplicity of PE, NE, and psychosocial context effects (PSCE) is currently limited when researching outcomes of diet changes in studies without randomisation and placebo control. This neglection is critical as it could systematically influence outcomes by moderating and mediating them and thus reducing the validity and evidence base of these studies. Therefore, we performed a (non-systematic) narrative review (NR) on the following objectives: (1) present a concise overview about the relevance of PE, NE, and PSCE in medicine and nutrition research; (2) review the current state of research on reflecting context effects when studying diet changes; (3) provide useful theoretical foundations via consideration and integration of micro- and macro context effects; (4) operationalise as hypotheses the potential PE, NE, and PSCE which are specific for researching diet changes; and (5) derive their impact for future research as well as for nutrition counselling. The electronic search in this NR for objective (2) identified N = 5 publications and for objective (4) we found N = 61 articles retrieved in the first round of search, additional references were identified by a manual and snowball search among the cited references resulting finally in N = 37. This NR offers a synoptical basis to foster awareness and operationalisation of a variety of PE, NE, and PSCE. Interdisciplinary research teams should monitor these factors using, e.g., qualitative, mixed-method studies, process evaluation, item bank approaches, moderator and mediator analysis that might reveal substantially new insights, and outcomes of relevance to science and nutrition counselling. Nevertheless, the present NR has several limitations, especially as it is non-systematic, because it is a very heterogeneous field of research, in which the topic we are investigating is usually regarded as marginal and subordinate. Therefore, future research should conduct systematic reviews and particularly theory-based primary studies (experimental research) on hypotheses of PE, NE, and PSCE in outcome research in diet changes.

Identifying and predicting subgroups of information needs among cancer patients: an initial study using latent class analysis.

PURPOSE: Understanding how the information needs of cancer patients (CaPts) vary is important because met information needs affect health outcomes and CaPts' satisfaction. The goals of the study were to identify subgroups of CaPts based on self-reported cancer- and treatment-related information needs and to determine whether subgroups could be predicted on the basis of selected sociodemographic, clinical and clinician-patient relationship variables. METHODS: Three hundred twenty-three CaPts participated in a survey using the "Cancer Patients Information Needs" scale, which is a new tool for measuring cancer-related information needs. The number of information need subgroups and need profiles within each subgroup was identified using latent class analysis (LCA). Multinomial logistic regression was applied to predict class membership. RESULTS: LCA identified a model of five subgroups exhibiting differences in type and extent of CaPts' unmet information needs: a subgroup with "no unmet needs" (31.4% of the sample), two subgroups with "high level of psychosocial unmet information needs" (27.0% and 12.0%), a subgroup with "high level of purely medical unmet information needs" (16.0%) and a subgroup with "high level of medical and psychosocial unmet information needs" (13.6%). An assessment of sociodemographic and clinical characteristics revealed that younger CaPts and CaPts' requiring psychological support seem to belong to subgroups with a higher level of unmet information needs. However, the most significant predictor for the subgroups with unmet information needs is a good clinician-patient relationship, i.e. subjective perception of high level of trust in and caring attention from nurses together with high degree of physician empathy seems to be predictive for inclusion in the subgroup with no unmet information needs. CONCLUSIONS: The results of our study can be used by oncology nurses and physicians to increase their awareness of the complexity and heterogeneity of information needs among CaPts and of clinically significant subgroups of CaPts. Moreover, regression analyses indicate the following association: Nurses and physicians seem to be able to reduce CaPts' unmet information needs by establishing a relationship with the patient, which is trusting, caring and empathic.

Barriers to using psycho-oncology services: a qualitative research into the perspectives of users, their relatives, non-users, physicians, and nurses.

PURPOSE: The present explorative study was designed as a qualitative evaluation of the psycho-oncology services (POS) available at a psycho-oncology institution (POI) in Germany. The study focused on barriers to using these services. METHODS: Seven focus groups and five complementary individual interviews were conducted with POS users, their relatives, and POS non-users from a German POI, as well as with oncology physicians and nurses from an affiliated hospital. The focus groups and individual interviews were audiotaped and fully transcribed. Data were analyzed using the documentary method. RESULTS: Four utilization barriers were identified: (1) patients' and physicians' information deficits about POI and POS, (2) patients' and physicians' subjective norms regarding POS, (3) lack of organizational and therapeutic integration of POI and POS into routine oncology care on the ward, and (4) specific characteristics of cancer patients. The most important finding was that lack of organizational and therapeutic integration of POS in routine oncology care on the ward might have a lasting, negative effect on patients' and physicians' information deficits and subjective norms. Furthermore, the identified utilization barriers seem to be a multi-causal problem with complex interdependencies. CONCLUSION: Based on these results, the organizational and therapeutic integration of POS in routine oncology care on the POI ward appears to be a useful tool in offering widely accessible therapies and providing patients with concise, straightforward information via different channels, such as personnel, brochures, and the Internet. Nevertheless, the results should be interpreted tentatively, due to the explorative character of this study.

The Worksite Health Promotion Capacity Instrument (WHPCI): development, validation and approaches for determining companies' levels of health promotion capacity.

BACKGROUND: The Worksite Health Promotion Capacity Instrument (WHPCI) was developed to assess two key factors for effective worksite health promotion: collective willingness and the systematic implementation of health promotion activities in companies. This study evaluates the diagnostic qualities of the WHPCI based on its subscales Health Promotion Willingness and Health Promotion Management, which can be used to place companies into four different categories based on their level of health promotion capacity. METHODS: Psychometric evaluation was conducted using exploratory factor and reliability analyses with data taken from a random sample of managers from n = 522 German information and communication technology (ICT) companies. Receiver operating characteristic (ROC) analyses were conducted to determine further diagnostic qualities of the instrument and to establish the cut-off scores used to determine each company's level of health promotion capacity. RESULTS: The instrument's subscales, Health Promotion Willingness and Health Promotion Management, are based on one-dimensional constructs, each with very good reliability (Cronbach's alpha = 0.83/0.91). ROC analyses demonstrated satisfactory diagnostic accuracy with an area under the curve (AUC) of 0.76 (SE = 0.021; 95% CI 0.72-0.80) for the Health Promotion Willingness scale and 0.81 (SE = 0.021; 95% CI 0.77-0.86) for the Health Promotion Management scale. A cut-off score with good sensitivity (71%/76%) and specificity (69%/75%) was determined for each scale. Both scales were found to have good predictive power and exhibited good efficiency. CONCLUSIONS: Our findings indicate preliminary evidence for the validity and reliability of both subscales of the WHPCI. The goodness of each cut-off score suggests that the scales are appropriate for determining companies' levels of health promotion capacity. Support in implementing (systematic) worksite health promotion can then be tailored to each company's needs based on their current capacity level.

Validation of the "SmoCess-GP" instrument - a short patient questionnaire for assessing the smoking cessation activities of general practitioners: a cross-sectional study.

BACKGROUND: We developed an instrument assessing the extent of smoking cessation activities by general practitioners (GPs) within the Cologne Smoking Study (CoSmoS). The objective of the present study was to examine further psychometric quality of the "SmoCess-GP" instrument (Smoking Cessation by General Practitioners). METHODS: 127 current smokers who had participated in the Cologne Smoking Study (CoSmoS) were included in our analyses. Confirmatory factor analysis (CFA) was conducted to examine the model fit and to retest the single-factor structure of the instrument using the Mplus software. Further construct validity was tested with bivariate analysis using an instrument which measures patients' trust in physicians. RESULTS: CFA supported the unidimensional structure of the instrument. The factor loadings exceed the threshold of > or = 0.50. All indicator reliabilities were higher than 0.30. The composite reliability was 0.86 and the average variance extracted (AVE) resulted in a value of 0.50. The calculation of global fit indices identified a CFI value of 1.00 and for TLI a value of 1.02. The root mean square error of approximation (RMSEA) indicates that 0% of the information is not accounted for by the model. The chi-square value was chi2df = 6 = 4.63 (p = 0.59). Analysis of discriminant validity resulted in a non-significant correlation of r = 0.092 (p = 0.350). CONCLUSIONS: Results indicate preliminary evidence for the construct validity of the "SmoCess-GP" instrument which therefore appears to be a promising tool for analyzing the extent of smoking cessation advice offered by GPs from the patients' perspective. Future research should examine the psychometric properties in a population based sample, further improvements of the instrument and should apply other methods of validation.

Assessing gait impairment following experimental traumatic brain injury in mice.

Although gait disturbance is frequently documented among patients with traumatic brain injury (TBI), gait data from animal models of TBI are lacking. To determine the effect of TBI on gait function in adult mice, we assessed gait changes following unilateral controlled cortical impact (CCI) using a computer-assisted automated gait analysis system. Three days after CCI, intensity, area or width of paw contact were significantly decreased in forepaw(s) while the relative paw placement between the fore and hindpaws altered, suggesting that TBI affected sensorimotor status and reduced interlimb coordination. Similar to TBI patients, CCI decreased gait velocity and stride length, and prolonged stance and swing phase in mice. Following CCI, step pattern was also changed with increasing use in the ipsilateral-diagonal limb sequence. Our results indicate that gait analysis provides great insight into both spatial and temporal aspects of limb function changes during overground locomotion in quadruped species with head injury that are valuable for the purpose of treatment and rehabilitation. Our study also provides additional functional validation for the established mouse CCI model that is relevant to human head injury.

Analyzing the "nature" and "specific effectiveness" of clinical empathy: a theoretical overview and contribution towards a theory-based research agenda.

OBJECTIVE: To establish sound empirical evidence that clinical empathy (abbreviated as CE) is a core element in the clinician-patient relationship with profound therapeutic potential, a substantial theoretical-based understanding of CE in medical care and medical education is still required. The two aims of the present paper are, therefore, (1) to give a multidisciplinary overview of the "nature" and "specific effectiveness" of CE, and (2) to use this base as a means of deriving relevant questions for a theory-based research agenda. METHOD: We made an effort to identify current and past literature about conceptual and empirical work focusing on empathy and CE, which derives from a multiplicity of disciplines. We review the material in a structured fashion. RESULTS: We describe the "nature" of empathy by briefly summarizing concepts and models from sociology, psychology, social psychology, education, (social-)epidemiology, and neurosciences. To explain the "specific effectiveness" of CE for patients, we develop the "Effect model of empathic communication in the clinical encounter", which demonstrates how an empathically communicating clinician can achieve improved patient outcomes. Both parts of theoretical findings are synthesized in a theory-based research agenda with the following key hypotheses: (1) CE is a determinant of quality in medical care, (2) clinicians biographical experiences influence their empathic behavior, and (3) CE is affected by situational factors. CONCLUSION: The main conclusions of our review are twofold. First of all, CE seems to be a fundamental determinant of quality in medical care, because it enables the clinician to fulfill key medical tasks more accurately, thereby achieving enhanced patient health outcomes. Second, the integration of biographical experiences and situational factors as determinants of CE in medical care and medical education appears to be crucial to develop and promote CE and ultimately ensuring high-quality patient care. PRACTICE IMPLICATIONS: Due to the complexity and multidimensionality of CE, evidence-based investigations of the derived hypotheses require both well-designed qualitative and quantitative studies as well as an interdisciplinary research approach.

The relationship between social capital in hospitals and physician job satisfaction.

BACKGROUND: Job satisfaction in the hospital is an important predictor for many significant management ratios. Acceptance in professional life or high workload are known as important predictors for job satisfaction. The influence of social capital in hospitals on job satisfaction within the health care system, however, remains to be determined. Thus, this article aimed at analysing the relationship between overall job satisfaction of physicians and social capital in hospitals. METHODS: The results of this study are based upon questionnaires sent by mail to 454 physicians working in the field of patient care in 4 different German hospitals in 2002. 277 clinicians responded to the poll, for a response rate of 61%. Analysis was performed using three linear regression models with physician overall job satisfaction as the dependent variable and age, gender, professional experience, workload, and social capital as independent variables. RESULTS: The first regression model explained nearly 9% of the variance of job satisfaction. Whereas job satisfaction increased slightly with age, gender and professional experience were not identified as significant factors to explain the variance. Setting up a second model with the addition of subjectively-perceived workload to the analysis, the explained variance increased to 18% and job satisfaction decreased significantly with increasing workload. The third model including social capital in hospital explained 36% of the variance with social capital, professional experience and workload as significant factors. CONCLUSION: This analysis demonstrated that the social capital of an organisation, in addition to professional experience and workload, represents a significant predictor of overall job satisfaction of physicians working in the field of patient care. Trust, mutual understanding, shared aims, and ethical values are qualities of social capital that unify members of social networks and communities and enable them to act cooperatively.

Psychometric evaluation of an instrument to assess patient-reported 'psychosocial care by physicians': a structural equation modeling approach.

OBJECTIVE: The objective of our study was to develop a theory-based and empirically tested instrument for measuring patient-reported 'psychosocial care by physicians'. We propose a model integrating patients' perceptions with respect to: (i) devotion by physicians, (ii) support by physicians, (iii) information by physicians and (iv) shared decision-making (SDM). DESIGN: Data were gathered during 2001 within a cross-sectional, retrospective mail survey. PARTICIPANTS AND SETTING: A total of 4192 inpatients of six German hospitals. MAIN OUTCOME MEASURE: Specific scales of the Cologne Patient Questionnaire were used. A two-step structural equation model procedure was applied. In the first structural equation model, all items were modeled as indicators of the intended underlying latent construct, 'psychosocial care by physicians'. In the second structural equation model, criterion-related validity of the intended construct was tested with respect to patients' 'satisfaction', 'trust in physicians' and the 'image of the hospital'. RESULTS: The results confirmed that the aspects of psychosocial care provided by physicians measured by the scale items are indeed indicators of the same construct. Furthermore, indicator reliabilities and selectivities revealed that the content of all 13 items was highly representative of the underlying construct. The second structural equation model showed that 'psychosocial care by physicians' is related to 'patients' satisfaction', 'trust in physicians' and 'hospital-image' in a significant and relevant manner. CONCLUSION: On the basis of our instrument's reported psychometric characteristics and of the initial validity indicators, it may be regarded as an adequate measure for further use in outcome and intervention research, and as a quality indicator for the physician-patient relationship.
