Does Being Ill Improve Acceptance of Medical Technology?-A Patient Survey with the Technology Usage Inventory.

Acceptance of new medical technology may be influenced by social conditions and an individual's background and particular situation. We studied this acceptance by hypothesizing that current and former COVID-19 patients would be more likely to accept an electrocardiogram (ECG) "patch" (attached to the chest) that allows continuous monitoring of the heart than individuals who did not have the disease and thus the respective experience. Currently infected COVID-19 patients, individuals who had recovered from COVID-19, and a control group were recruited online through Facebook (and Instagram) and through general practitioners (GPs). Demographic information and questions tailored to the problem were collected via an online questionnaire. An online survey was chosen in part because of the pandemic conditions, and Facebook was chosen because of the widespread discussions of health topics on that platform. The results confirmed the central hypothesis that people who had experienced a disease are more willing to accept new medical technologies and showed that curiosity about new technologies and willingness to use them were significantly higher in the two groups currently or previously affected by COVID-19, whereas fears of being "monitored" (in the sense of surveillance) were significantly higher among people who had not experienced the disease and threat. Experiencing a serious disease ("patient experience") promotes acceptance of new medical technologies.

Empirical Research on Acceptance of Digital Technologies in Medicine Among Patients and Healthy Users: Questionnaire Study.

BACKGROUND: In recent years, interest in digital technologies such as electronic health, mobile health, telemedicine, big data, and health apps has been increasing in the health care sector. Acceptance and sustainability of these technologies play a considerable role for innovative health care apps. OBJECTIVE: This study aimed to identify the spread of and experience with new digital technologies in the medical sector in Germany. METHODS: We analyzed the acceptance of new health care technologies by applying the Technology Acceptance Model to data obtained in the German ePatient Survey 2018. This survey used standardized questionnaires to gain insight into the prevalence, impact, and development of digital health applications in a study sample of 9621 patients with acute and chronic conditions and healthy users. We extracted sociodemographic data and details on the different health app types used in Germany and conducted an evaluation based on the Technology Acceptance Model. RESULTS: The average age of the respondents was 59.7 years, with a standard deviation of 16 years. Digital health care apps were generally accepted, but differences were observed among age groups and genders of the respondents. Men were more likely to accept digital technologies, while women preferred coaching and consultation apps. Analysis of the user typology revealed that most users were patients (n=4041, 42%), followed by patients with acute conditions (n=3175, 33%), and healthy users (n=2405, 25%). The majority (n=6542, 68%) discovered coaching or medication apps themselves on the internet, while more than half of the users faced initial difficulties operating such apps. The time of use of the same app or program ranged from a few days (n=1607, 37%) and several months (n=1694, 39%) to ≥1 year (n=1042, 24%). Most respondents (n=6927, 72%) stated that they would like to receive customized health care apps from their physician. CONCLUSIONS: The acceptance of digital technologies in the German health care sector varies depending on age and gender. The broad acceptance of medical digital apps could potentially improve individualized health care solutions and warrants governance.

An introduction to the 'Psycho-Physiological-Stress-Test' (PPST)-A standardized instrument for evaluating stress reactions.

Using a standardized instrument to evaluate patients' stress reactions has become more important in daily clinical routines. Different signs or symptoms of stress are often unilaterally explored: the physiological, psychological or social aspects of stress disorders are each viewed on a single dimension. However, all dimensions afflict patients who have persistent health problems due to chronic stress. Therefore, it is important to use a multidimensional approach to acquire data. The 'Psycho-Physiological-Stress-Test' (PPST) was established to achieve a comprehensive understanding of stress and was further developed at the Charité-Universitätsmedizin Berlin in collaboration with the Psychological Department of Freie Universität Berlin. The PPST includes a series of varying stress phases, embedded in two periods of rest. Physiological and psychological parameters are simultaneously measured throughout the test session. Specifically, the PPST activates the sympathetic stress axis, which is measured by heart rate, blood pressure, respiration depth and rate, electro dermal activation and muscle tension (frontalis, masseter, trapezius). Psychological data are simultaneously collected, and include performance, motivation, emotion and behavior. After conducting this diagnostic test, it is possible to identify individual stress patterns that can be discussed with the individual patient to develop and recommend (outpatient) treatment strategies. This paper introduces the PPST as a standardized way to evaluate stress reactions by presenting the results from a sample of psychosomatic inpatients (n = 139) who were treated in Charité-Universitätsmedizin Berlin, Germany. We observed that the varying testing conditions provoked adjusted changes in the different physiological parameters and psychological levels.

Work family conflict in its relations to perceived working situation and work engagement.

BACKGROUND: These days physicians' work is characterized by an increase in economic demands, pressure and challenges in establishing a balance between work and family life. The current study investigates the relationship between physicians' job demands and resources, perceived job stress, work-family conflict, work engagement and job satisfaction. METHODS: 564 clinicians specialising in different medical fields participated in the cross-sectional study. Self-administered questionnaires, including the COPSOQ and the UWES- Scale were administered. RESULTS: Our results illustrated significant relationships between physicians' work engagement and their job satisfaction as well as between job stress and work family conflict. Moreover, perceived job stress moderated the effect of high job demands on work family conflict. In addition, significant gender differences have been found in perceived stress levels, work family conflict and work engagement. CONCLUSION: This study proves and verified associations between work engagement, work-family conflict, job demands and resources that may influence employees' satisfaction. Implications for both working physicians and hospital management are given.

An Evaluation of a Multicomponent Mental Competency and Stress Management Training for Entrants in Surgery Medicine.

OBJECTIVE: Stress occurs in surgeons with a significantly higher prevalence than in the general population. At the same time, learning of coping techniques and improving personal skills how to handle the daily workload are not integral parts of the medical education or during adjustment to the job as a surgeon. In this pilot study, we developed a training course to teach different stress management and coping techniques and analyzed individual conditions of the surgeons before and after the course. METHODS: In total, 68 junior surgeons in their first year at work participated in the training and were randomized in an intervention (n = 35) or a control group (n = 33). At the beginning and the end of the training, the intervention and the comparison group answered a standardized, validated questionnaire on job satisfaction, perceived stress, and personal skills (such as self-efficacy). RESULTS: The surgeons showed a significant decline in perceived stress. Furthermore, they showed an improvement in self-reported resilience and self-efficacy. Job satisfaction increased at the same time. The comparison cohort of surgeons showed comparable scores for the specified outcome variables at the beginning but showed no progressive changes during time. CONCLUSIONS: The study findings indicate that the training for junior surgeons in their first year at work is suitable to implement as a group training program. Moreover, the training provides statistically significant improvement in perceptions of distress and strengthens individual protective factors and job satisfaction.

Managing work-family conflict in the medical profession: working conditions and individual resources as related factors.

OBJECTIVES: This study developed and tested a research model that examined the effects of working conditions and individual resources on work-family conflict (WFC) using data collected from physicians working at German clinics. MATERIAL AND METHODS: This is a cross-sectional study of 727 physicians working in German hospitals. The work environment, WFC and individual resources were measured by the Copenhagen Psychosocial Questionnaire, the WFC Scale, the Brief Resilient Coping Scale and the Questionnaire for Self-efficacy, Optimism and Pessimism. Descriptive, correlation and linear regression analyses were applied. RESULTS: Clinical doctors working in German hospitals perceived high levels of WFC (mean=76). Sociodemographic differences were found for age, marital status and presence of children with regard to WFC. No significant gender differences were found. WFCs were positively related to high workloads and quantitative job demands. Job resources (eg, influence at work, social support) and personal resources (eg, resilient coping behaviour and self-efficacy) were negatively associated with physicians' WFCs. Interaction terms suggest that job and personal resources buffer the effects of job demands on WFC. CONCLUSIONS: In this study, WFC was prevalent among German clinicians. Factors of work organisation as well as factors of interpersonal relations at work were identified as significant predictors for WFC. Our results give a strong indication that both individual and organisational factors are related to WFC. Results may play an important role in optimising clinical care. Practical implications for physicians' career planning and recommendations for future research are discussed.

Adjustment disorders as a stress-related disorder: a longitudinal study of the associations among stress, resources, and mental health.

OBJECTIVE: Adjustment disorders are re-conceptualized in the DSM-5 as a stress-related disorder; however, besides the impact of an identifiable stressor, the specification of a stress concept, remains unclear. This study is the first to examine an existing stress-model from the general population, in patients diagnosed with adjustment disorders, using a longitudinal design. METHODS: The study sample consisted of 108 patients consecutively admitted for adjustment disorders. Associations of stress perception, emotional distress, resources, and mental health were measured at three time points: the outpatients' presentation, admission for inpatient treatment, and discharge from the hospital. To evaluate a longitudinal stress model of ADs, we examined whether stress at admission predicted mental health at each of the three time points using multiple linear regressions and structural equation modeling. A series of repeated-measures one-way analyses of variance (rANOVAs) was performed to assess change over time. RESULTS: Significant within-participant changes from baseline were observed between hospital admission and discharge with regard to mental health, stress perception, and emotional distress (p<0.001). Stress perception explained nearly half of the total variance (44%) of mental health at baseline; the adjusted R2 increased (0.48), taking emotional distress (i.e., depressive symptoms) into account. The best predictor of mental health at discharge was the level of emotional distress (i.e., anxiety level) at baseline (ß= -0.23, R2corr=0.56, p<0.001). With a CFI of 0.86 and an NFI of 0.86, the fit indices did not allow for acceptance of the stress-model (Cmin/df=15.26; RMSEA=0.21). CONCLUSIONS: Stress perception is an important predictor in adjustment disorders, and mental health-related treatment goals are dependent on and significantly impacted by stress perception and emotional distress.

Surgeons' work engagement: influencing factors and relations to job and life satisfaction.

BACKGROUND: Work engagement has become a topic of great interest in recent years. However, clinicians' work engagement has rarely been studied and relatively little is known about its predictors and consequences. Therefore the objective of this cross-sectional questionnaire study was to test a model of possible institutional and personal predictors and significant relations to job and life satisfaction. METHODS: 123 clinicians specializing in Surgery Medicine participated in the study. Self-administered questionnaires, including the Copenhagen Psychosocial Questionnaire, the Utrecht Work Engagement Scale, the Brief Resilient Coping Scale and the Questionnaire for Self-efficacy, Optimism and Pessimism, were administered. Bivariate analyses and a stepwise regression analysis were performed. RESULTS: The whole sample of surgeons rated work engagement with a high mean of M = 4.38; SD = .91. Job satisfaction and perceived quality of life have been rated with moderate scores. The results show that job resources have a greater impact on surgeons' work engagement than their job demands. Significant correlations between surgeons' work engagement, their job satisfaction and quality of life were found. Moreover, work engagement mediated the relation between institutional factors and surgeons' job satisfaction. CONCLUSION: Our research suggests that strengthening surgeons' work engagement will contribute to a more sustainable workplace, in terms of both individual and hospital performance. Therefore, increasing work engagement among surgeons should be of concern for supervisors and hospital managers. Future research should focus on further predictors that may have an influence on health professionals' work engagement. Another field for future research is to study potential effects of interventions on work engagement.

Exploring the impact of resilience, self-efficacy, optimism and organizational resources on work engagement.

BACKGROUND: The German health care system has undergone radical changes in the last decades. These days health care professionals have to face economic demands, high performance pressure as well as high expectations from patients. To ensure high quality medicine and care, highly intrinsic motivated and work engaged health care professionals are strongly needed. OBJECTIVE: The aim of this study was to examine relations between personal and organizational resources as essential predictors for work engagement of German health care professionals. METHODS: This investigation has a cross-sectional questionnaire study design. Participants were a sample of hospital doctors. Personal strengths, working conditions and work engagement were measured by using the SWOPE-K9, COPE Brief Questionnaire, Perceived Stress Questionnaire, COPSOQ and Utrecht Work Engagement Scale. RESULTS: Significant relations between physicians' personal strengths (e.g. resilience, optimism) and work engagement were evaluated. Work related factors showed to have a significant influence on work engagement. Differences in work engagement were also found with regard to socio-demographic variables. CONCLUSION: Results demonstrated important relationships between personal and organizational resources and work engagement. Health care management needs to use this information to maintain or develop work engaging job conditions in hospitals as one key factor to ensure quality health care service.

The trade-off between costs and quality of care in the treatment of psychosomatic patients with somatoform pain disorder.

BACKGROUND: The introduction of efficiency-oriented provider payment systems in inpatient mental healthcare in various Western countries may lead to the use of less healthcare resources in the treatment of patients. To avoid unintended effects on quality of care that may result from reductions in resource utilization, it is essential for decision and policy makers to know whether there is a trade-off between costs and quality of care. AIM OF THE STUDY: The aim of this study was to investigate and quantify the relationship between costs and outcomes in psychosomatic inpatients with somatoform pain disorder. METHODS: The inclusion criteria for patient selection (n = 101) were (i) a main diagnosis of somatoform pain disorder according to International Classification of Diseases-10 (ICD-10) [F45.4, F45.40, F45.41]; (ii) complete data on the mental component summary reflecting overall functioning of mental health (MCS-8) measured with the Short Form-8 Health Survey (SF-8) within 3 days of the admission and discharge dates; and (iii) treatment at Charité Universitaetsmedizin (Berlin, Germany) during the period January 2006-June 2010. The change in the MCS-8 score incurred over the treatment period was used as an indicator of quality of care. Treatment costs were calculated from the provider's perspective, mainly using bottom-up micro-costing. The year of valuation for cost calculation was 2008 (with no inflation adjustment); for costs provided by the accounting department for services consumed by the patient, the valuation year was based on the year of service provision. We hypothesized that the outcome 'change in MCS-8 score' was a function of the independent variable costs, patient characteristics, socio-demographic variables, pain-related variables, co-morbidities and subjective illness attribution, i.e. whether patients attributed the origin of pain mainly to a somatic cause or not. An interaction term between costs and illness attribution was included to control for the hypothesized differing effects of resource input or costs on the outcome variable conditional on patients' illness attribution. Hausman tests indicated that endogeneity was not present, thus, ordinary least squares regression (OLS) was conducted. We assessed whether the change in the MCS-8 score was clinically meaningful and perceptible by the patient, using the minimal clinical important difference (MCID). For Short Form Health Surveys, the MCID for changes in the mental component summary is typically around 3 points. RESULTS: We found a trade-off between costs and outcome for patients without or with only minor somatic illness attribution (77 % of the sample). This patient group improved 0.4 points in outcome after every 100 increase in total costs per case (F 1,77 = 13.836, t(77) = 3.72, p = 0.0004). For patients with mainly somatic illness beliefs (23 % of the sample), we did not find a trade-off between costs and outcome. CONCLUSION: For the majority of patients, we found a trade-off between costs and health outcome, thus, it seems advisable to carefully monitor outcome parameters when applying cost containment measures.

Surgeons' work ability and performance in surgical care: relations between organisational predictors, work engagement and work ability.

BACKGROUND: The aim of this study was to examine relations and influences between work-related factors, personal resources, work engagement and work ability of surgeons working in German hospitals. METHODS: The study was conducted as a cross-sectional survey investigation. We used the Utrecht Work Engagement Scale, the Copenhagen Psychosocial Questionnaire and the Work Ability Index to evaluate surgeons' work engagement, working conditions and work ability. Bivariate analyses and a stepwise regression analysis were performed. RESULTS: Surgeons reported a moderate work ability and work engagement. The results indicated significant associations between surgeons' sources of work engagement, work ability and work-related factors (e.g. job resources). Significant differences regarding these variables were also detected between males and females and the various age groups. CONCLUSION: The study results reflect the positive effect of supportive working conditions and work engagement on the preservation of work ability, indicating their importance in promoting surgeons' work ability. Due to the elderly population and the continuing development of health care in Germany, the demand for surgeons increases. These circumstances give reasons for a strong need to preserve and restore surgeons' work ability. New strategies for training and improving the capacity and performance of surgeons are necessary.

Introduction of DRG-based reimbursement in inpatient psychosomatics--an examination of cost homogeneity and cost predictors in the treatment of patients with eating disorders.

OBJECTIVE: Various western countries are focusing on the introduction of reimbursement based on diagnosis-related groups (DRG) in inpatient mental health. The aim of this study was to analyze if psychosomatic inpatients treated for eating disorders could be reimbursed by a common per diem rate. METHODS: Inclusion criteria for patient selection (n=256) were (1) a main diagnosis of anorexia nervosa (AN), bulimia nervosa (BN) or eating disorder-related obesity (OB), (2) minimum length of hospital stay of 2 days, (3) and treatment at Charité Universitaetsmedizin Berlin, Germany during the years 2006-2009. Cost calculation was executed from the hospital's perspective, mainly using micro-costing. Generalized linear models with Gamma error distribution and log link function were estimated with per diem costs as dependent variable, clinical and patient variables as well as treatment year as independent variables. RESULTS: Mean costs/case for AN amounted to 5,251€, 95% CI [4407-6095], for BN to 3,265€, 95% CI [2921-3610] and for OB to 3,722€, 95% CI [4407-6095]. Mean costs/day over all patients amounted to 208€, 95% CI [198-218]. The diagnosis AN predicted higher costs in comparison to OB (p=.0009). A co-morbid personality disorder (p=.0442), every one-unit increase in BMI in OB patients (p=.0256), every one-unit decrease in BMI in AN patients (p=.0002) and every additional life year in BN patients (p=.0455) predicted increased costs. CONCLUSION: We see a need for refinements to take into account considerable variations in treatment costs between patients with eating disorders due to diagnosis, BMI, co-morbid personality disorder and age.

Inpatient costs and predictors of costs in the psychosomatic treatment of anorexia nervosa.

OBJECTIVE: In German inpatient psychosomatics per diem lump sums will be introduced as reimbursement rates by 2013. It was the aim to calculate total inpatient costs per case for the psychosomatic treatment of patients with anorexia nervosa and to identify cost predictors. METHOD: The sample comprised of 127 inpatients. Cost calculation was executed from the hospital's perspective, mainly using microcosting. Medical records provided data on patient characteristics and individual resource use. Two generalized linear models with gamma distribution and log link function were estimated to determine cost predictors by means of demographic data, comorbidities, and body-mass-index at admission. RESULTS: Inpatient costs amounted to 4,647 €/6,831 US$ per case (standard deviation 3,714 €/5,460 US$).The admission BMI and "Disorders of Adult Personality and Behavior" were significant cost predictors (p < 0.05). DISCUSSION: The formation of patient groups within the diagnosis anorexia nervosa should be oriented towards the determined cost predictors.

Gender-specific differences associated with living donor liver transplantation: a review study.

Living donor liver transplantation (LDLT) has developed into an important therapeutic option for liver diseases. For living donor kidney transplantation (LDKT), gender-specific differences have been observed among both donors (two-thirds being women and one-third being men) and recipients (two-thirds being men and one-third being women). The aim of this study was to determine whether there is a gender disparity for LDLT. We contacted 89 national and international transplantation registries, single transplant centers, and coordinators. In addition, a sample of 274 articles dealing with LDLT and its outcomes was reviewed and compared with the registry data. The data included the gender of the donors and recipients, the country of transplantation, and the donor-recipient relationship. The investigation showed that overall there were slightly more men among the donors (53% male and 47% female). As for the recipients, 59% of the organs were distributed to males, and 41% were distributed to females. Differences in the gender distribution were observed with respect to individual countries. Worldwide, 80% of the donors were blood-related, 11% were not blood-related, and 9% were spouses. The data acquired from the publications were similar to the registry data. Our research has shown that there are hardly any registry data published, a lot of countries do not have national registries, or the access to these data is difficult. Even widely ranging published studies often do not give information on the gender distribution or the donor-recipient relationship. Further investigations are needed to understand the possible medical, psychosocial, or cultural reasons for gender distribution in LDLT and the differences in comparison with LDKT.

[DRGs and daily rates of pay in psychosomatics: 2002-2005]. / DRGs und Pflegesätze in der Psychosomatik: 2002-2005.

OBJECTIVES: Over the last years the use of diagnosis-related groups (G-DRG) was introduced into most areas of the German health care system, which led to changed compensation for departments outside the G-DRG system as well. We evaluated the development of revenues in 17 different psychosomatic departments over the last three years. METHODS: Our analyses were based on official daily rates for each of the clinics included. If daily rates changed within one year, we used the average daily rate for that year. RESULTS: Together all departments provided 547 in-patient beds for the treatment of acute psychosomatic patients. With 85% occupancy all departments would achieve a revenue of 62.5 million euro in 2005, two million euro less than three years previously. Due to the introduction of the German DRG system their average income was reduced by approx. 3%. The loss was greater for psychosomatic departments at larger hospitals, which have a higher percentage of departments included in the G-DRG system. CONCLUSIONS: The introduction of the G-DRG system leads to reduced revenues for departments outside the G-DRG system, while performance was expected to remain at the same level and costs have increased. Thus, to ensure the spectrum of psychosomatic medicine as it is today, it has become increasingly important to demonstrate the real costs of treatment to political decision makers.

Impaired psychosocial outcome of donors after living donor liver transplantation: a qualitative case study.

Adult-to-adult living donor liver transplantation (LDLT) of the right hepatic lobe has been developing into an established therapy for treating pre-terminal liver diseases. There is little experience available on the psychosocial outcome of living donors. The aim of this first qualitative case study was to investigate the patterns for impaired psychosocial outcome in donors after LDLT. Donor hepatectomies were performed in 30 donors at the Charité Berlin. Six months after surgery, the six of the 30 donors with negative moods and physical complaints in psychometric monitoring were examined. The post-operative interviews were transcribed and analysed using current qualitative research methods. These six donors (20%) reported various unspecific complaints and psychological conflicts. Sadness was expressed about organ rejection and death of the recipient. Anxieties about the recipient and their own health were verbalized. Disappointment and anger refer to the experience that they were not as fully appreciated by the medical system and their social environment as expected. The negative emotions of donors with impaired psychosocial outcome could be related to a decrease in self-esteem in the post-operative course. Adequate medical and psychological treatment opportunities for these donors should be provided.

[Evaluation of the effectiveness of psychosomatic in-patient treatment on the basis of subjective and objective criteria]. / Evaluation stationärer psychosomatischer Behandlung anhand subjektiver und objektiver Kriterien.

OBJECTIVES: The effectiveness of psychosomatic in-patient treatment was evaluated using patients' subjective health ratings and objective data provided by health insurance companies. Associations between subjective and objective criteria were investigated. METHODS: 318 patients participated in the study. They completed questionnaires on physical complaints, moods and everyday functioning upon hospital admission, at discharge and at one-year follow-up. Insurance companies provided data for 140 of these patients (44 %). Sick leave and the utilization of in-patient treatment were assessed for a period of two years before and two years after psychosomatic treatment. RESULTS: As expected, subjective health status improved. The utilization of in-patient treatment decreased in both years after treatment compared to the year before. Sick leave increased in the first year after treatment but decreased significantly below the base level in the second year after treatment. Self-efficacy expectations and being employed were found to be predictors for long-term reduction in the length of in-patient treatment. Subjective and objective criteria were only slightly correlated. CONCLUSIONS: Sick leave and utilization of in-patient treatment were found to increase considerably in the year before psychosomatic treatment. Therefore, pre-post differences over the entire period were only marginal. The change in subjective criteria was more immediate, while changes in some objective parameters were delayed. Both subjective and objective criteria should be included in outcome studies.

Psychosocial situation of living donors: moods, complaints, and self-image before and after liver transplantation.

BACKGROUND: Living donor liver transplantation (LDLT) has developed into an established therapy for terminal liver diseases. There is, however, little knowledge of the psychosocial situation of living donors. The aim of this study was to investigate the course of donors' moods, physical complaints, and self-image in the preoperative decision process and six months after surgery. MATERIAL/METHODS: Fifty-two potential donors were evaluated at the Charité Berlin. On the basis of the clinical interview, seven (13%) potential donors were not recommended for LDLT for psychosocial reasons. Twenty-six donors underwent liver resection and were re-evaluated six months after surgery. Donors' moods were investigated with the Berlin Mood Questionnaire (BMQ) and their physical complaints were assessed by the Giessen Complaint Questionnaire (GCQ). The Narcissism Inventory (NI-90) was used to assess their self-image. RESULTS: Potential donors who were not recommended for surgery showed significantly higher values for negative moods, physical complaints, and 'narcissistic rage". After surgery, donors' self-images were generally stabilized. Nevertheless, five donors (19%) showed high values for "threatened self" before and after transplantation, as well as high values for negative moods and complaints after LDLT. CONCLUSIONS: The resection of the right hepatic lobe holds promise of a good psychosocial outcome, with stable self-image and self-esteem for most donors. A minority of donors exhibited enhanced perception of distress and low self-esteem before and after surgery, which can easily be overlooked in the preoperative evaluation. A psychometric assessment of self-image before transplantation should be added to the clinical interview evaluation of potential living donors.

Advanced anorexia nervosa, associated with pneumomediastinum, pneumothorax, and soft-tissue emphysema without esophageal lesion.

OBJECTIVE: We describe the case of a 20-year-old female patient suffering from anorexia nervosa since the age 15 of years. When admitted, she was 168 cm tall with a weight of 35 kg (body mass index [BMI] = 12.4). A week after admission, the patient complained of retrosternal pain, and a few hours later she developed extensive soft-tissue emphysema. METHODS: The X-ray picture of her thorax showed left-hand supraclavicular and infraclavicular emphysema, extensive emphysema in both sides of the soft tissue of the throat, a left-hand apical pneumothorax (4 mm), and a pneumomediastinum. RESULTS: We discuss the extent to which these symptoms are interrelated in the sense of a causal nexus. CONCLUSION: We ruled out any other differential-diagnostic etiopathogenic factors and concluded that the cause of our patient's soft-tissue emphysema, pneumothorax, and pneumomediastinum might well be autodestructive behavior.

Autodestructive syndromes.

BACKGROUND: The phenomenon 'autodestructive behaviour' is becoming an increasingly serious disease and cost factor in a wide range of medical fields. The present paper presents a survey of the literature on autodestructive behaviour, excluding psychotic, substance-induced or organic brain disorders. Starting out with a conceptual overview, the paper goes on to look into the epidemiology of autodestructive behaviour and the forms in which it manifests itself. METHOD: A literature search was conducted in Medline, Psycinfo and Psyndex using the search terms 'artifact', 'artificially induced', 'autodestructive', 'self-mutilation', 'factitious', 'self-harm', 'self-induced', 'self-inflicted', 'self-injuring' and 'self-mutilation' for the period from 1977 to 2003. RESULTS: Five of a total of 18 empirical studies describe the simultaneous occurrence of direct and indirect forms of autodestructive behaviour. Reported prevalence rates range from 0.032% to 9.36%. The ratio of females to males was found to be 2:1 (average age: 31.5 years; SD: 9.3 years); in contrast, the gender ratio was reversed for Munchausen's syndrome. The case history data presented are patchy and differ in terms of their priorities. We found a large number of codiagnoses, which seems to indicate that personality and dependence disorders, or substance misuse, are characteristic of both direct and indirect forms of autodestructive behaviour. CONCLUSIONS: The task at hand is to use a yet-to-be-developed nomenclature and adequately operational diagnostic criteria to work out standardised survey instruments that do justice to the heterogeneity of this disorder complex.
