BACKGROUND:QUALIDEM is a standardized dementia-specific quality of life (Qol) measurement, which was developed and validated in the Netherlands. A German version has been available since 2008. This study protocol describes the design and methodology for the quality of life of people with dementia (Qol-Dem) project.OBJECTIVE:This project aims to evaluate the reliability and validity of the German version of the QUALIDEM.METHOD:Due to the lack of both a universal definition of Qol and of standards to verify the validity of Qol measurements, this study is divided into three phases. The aim of the first theoretical phase is the development of a dementia-specific Qol model as a result of a meta-synthesis of qualitative studies. The second empirical phase consists of the three following steps: (a) an investigation of the scalability and internal consistency of the measure, (b) an evaluation of the interrater and intrarater reliability, and (c) an extensive evaluation of the validity of the QUALIDEM. The resulting Qol model (phase 1) will be used for the selection of appropriate comparators for validity testing. In the third phase, the QUALIDEM will be adapted, if necessary, based on the knowledge generated in the first two phases.CONCLUSION:The findings of the Qol-Dem project should deliver an accurate assessment of the psychometric properties of the German version of the QUALIDEM. The results will contribute to the further development of the instrument. Furthermore, the results will contribute to the theoretical development of the concept of Qol among people with dementia.
Aim: Although seriously injured patients account for a high medical as well as socioeconomic burden of disease in the German health care system, there are only very few data describing the costs that arise between the days of accident and occupational reintegration. With this study, a comprehensive cost model is developed that describes the direct, indirect and intangible costs of an accident and their relationship with socioeconomic background of the patients. Methods: This study included 113 patients who each had at least two injuries and a total Abbreviated Injury Scale (AIS) greater than or equal to five. We calculated the direct, indirect and intangible costs that arose between the day of the accident and occupational reintegration. Direct costs were the treatment costs at hospitals and rehabilitation centers. Indirect costs were calculated using the human capital approach on the basis of the work days lost due to injury, including sickness allowance benefits. Intangible costs were assessed using the Short Form Survey (SF-36) and represented in non-monetary form. Following univariate analysis, a bivariate analysis of the above costs and the patients’ sociodemographic and socioeconomic characteristics was performed. Results: At an average Injury Severity Score (ISS) of 19.2, the average direct cost per patient were €35,661. An average of 185.2 work days were lost, resulting in indirect costs of €17,205. The resulting total costs per patient were €50,431. A bivariate analysis showed that the costs for hospital treatment were 58% higher in patients who graduated from lower secondary school [Hauptschule] (ISS 19.5) than in patients with qualification for university admission [Abitur] (ISS 19.4). Conclusions: The direct costs of treating trauma patients at the hospital appear to be lower in patients with a higher level of education than in the comparison group with a lower educational level. Because of missing data, the calculated indirect costs can merely represent a general trend, so that the bivariate analysis can only be seen as a starting point for further studies.
OBJECTIVE:General self-efficacy has been found to be an influential variable related to the adaptation to stress and chronic illness, with the General Self-Efficacy (GSE) Scale by Jerusalem and Schwarzer being a reliable and valid instrument to assess this disposition. The aim of this study was to construct and test a short form of this scale to allow for a more economical assessment of the construct.METHODS:The item characteristics of the original scale were assessed using an intercultural non-clinical sample (n=19,719). Six items with the highest coefficient of variation and good discrimination along the range of the trait were selected to build a short form of the instrument (GSE-6). Subsequently, the psychometric properties and the concurrent and predictive validity of the GSE-6 were tested in a longitudinal design with three measurements using a sample of patients with risk factors for heart failure (n=1,460).RESULTS:Cronbach's alpha for the GSE-6 was between .79 and .88. We found negative associations with symptoms of depression (-.35 and -.45), anxiety (-.35), and vital exhaustion (-.38) and positive associations with social support (.30), and mental health (.36). In addition, the GSE-6 score was positively associated with active problem-focused coping (.26) and distraction/self-encouragement (.25) and negatively associated with depressive coping (-.34). The baseline GSE-6 score predicted mental health and physical health after 28 months, even after controlling for the respective baseline score. The relative stability over twelve and 28 months was r=.50 and r=.60, respectively, while the mean self-efficacy score did not change over time.CONCLUSIONS:The six item short form of the GSE scale is a reliable and valid instrument that is useful for the economical assessment of general self-efficacy in large multivariate studies and for screening purposes.
Objective: This article includes the examination of potential methodological problems of the application of a forced choice response format in facial emotion recognition. Methodology: 33 subjects were presented with validated facial stimuli. The task was to make a decision about which emotion was shown. In addition, the subjective certainty concerning the decision was recorded. Results: The detection rates are 68% for fear, 81% for sadness, 85% for anger, 87% for surprise, 88% for disgust, and 94% for happiness, and are thus well above the random probability. Conclusion: This study refutes the concern that the use of forced choice formats may not adequately reflect actual recognition performance. The use of standardized tests to examine emotion recognition ability leads to valid results and can be used in different contexts. For example, the images presented here appear suitable for diagnosing deficits in emotion recognition in the context of psychological disorders and for mapping treatment progress.
Background: In view of the increasing number of implanted cardioverter defibrillators (ICD), the number of people suffering from so-called “multiple ICD shocks” is also increasing. The delivery of more than five shocks (appropriate or inappropriate) in 12 months or three or more shocks (so called multiple shocks) in a short time period (24 hours) leads to an increasing number of patients suffering from severe psychological distress (anxiety disorder, panic disorder, adjustment disorder, post-traumatic stress disorder). Untreated persons show chronic disease processes and a low rate of spontaneous remission and have an increased morbidity and mortality. Few papers have been published concerning the psychotherapeutic treatment for these patients. Objective: The aim of this study is to develop a psychotherapeutic treatment for patients with a post-traumatic stress disorder or adjustment disorder after multiple ICD shocks. Design: Explorative feasibility study: Treatment of 22 patients as a natural design without randomisation and without control group. The period of recruitment was three years, from March 2007 to March 2010. The study consisted of two phases: in the first phase (pilot study) we tested different components and dosages of psychotherapeutic treatments. The final intervention programme is presented in this paper. In the second phase (follow-up study) we assessed the residual post-traumatic stress symptoms in these ICD patients. The time between treatment and follow-up measurement was 12 to 30 months. Population: Thirty-one patients were assigned to the Department of Psychocardiology after multiple shocks. The sample consisted of 22 patients who had a post-traumatic stress disorder or an adjustment disorder and were willing and able to participate. They were invited for psychological treatment. 18 of them could be included into the follow-up study. Methods: After the clinical assessment at the beginning and at the end of the inpatient treatment a post-treatment assessment with questionnaires followed. In this follow-up measurement, minimum 12 months after inpatient treatment, posttraumatic stress was assessed using the “Impact of Event Scale” (IES-R). Setting: Inpatient treatment in a large Heart and Thorax Centre with a Department of Psychocardiology (Kerckhoff Heart Centre). Results: From the 18 patients in the follow-up study no one reported complaints of PTSD. 15 of them reported a high or even a very high decrease of anxiety and avoidance behaviour. Conclusions: The fist step of the treatment development seems to be successful. It shows encouraging results with an acceptable dosage. The second step of our work is in process now: we evaluate the treatment manual within other clinical institutions and a higher number of psychotherapists. This leads in the consequence to a controlled and randomised comparison study.
Objectives: Because of the fluctuating and occasional character of Crohn’s disease (CD), patients have to cope with a changeable condition of health. Personal perceived control is known to be an important element of adaptation to their medical condition. The objectives of this work are to determine if perceived personal control is predictive of the clinical activity of the disease and of psychological distress (depression, anxiety). Methods: The Hospital Anxiety Depression Scale (HADS), the causal dimension scale and the Clinical Global Impression (CGI; assessing perceived severity) were administered to 160 patients affected by Crohn’s disease. Indicators of inflammation (CRP), disease duration and clinical activity of the disease were also asessed. Results: Globally, CD patients perceive their disease as being personally neither controllable nor uncontrollable. Whereas psychological distress is significantly higher when the disease is active, the relationship between the variables appears complex. The feeling of personal control is explained by the clinical activity of the disease (p=.0001) and by the perception that CD is unstable (p<.00001) and globally impacts the life of patients (p=.001). Nevertheless perception of personal control does not explain the clinical activity of the disease. Finally, psychological distress is explained by the perception that the medical team is unable to control the disease (p=.00001) and by the global consequences of the disease on life (p<.005). Conclusions: Psychological treatments should take these dimensions into account so as to improve the well-being and medical conditions of patients.
Objective: The Pain Catastrophizing Scale, adapted for children (PCS-C) by Crombez et al. (2003), was translated into German (SKS-D) and evaluated regarding its factorial structure, its reliability and validity. The association of catastrophizing with various pain characteristics and disability measures was examined as well as its association to neighboring constructs. Method: The paper-and-pencil version of the SKS-D was used in two different samples of children and adolescents. Analyses were conducted on a subgroup of participants from an epidemiological sample [n=898; age: M=12.9 (SD=1.4)] who had experienced monthly headaches in the 6-months period before and a clinical sample [n=60; age: M=12.6 (SD=0.8)] seeking treatment for recurrent headaches. Results: Exploratory factor analysis (PCA) suggested a one-factor model in contrast to the 3-factor model suggested by Crombez et al. (2003). The unidimensional scale showed distinct homogeneity and satisfying reliability. The clinical sample showed significantly higher scores than the epidemiological group. Also girls scored higher than boys. The catastrophizing explained a considerable amount of variance in pain and disability parameters in both samples thus underlining its validity. The psychological variables internalising, anxiety sensitivity and somatosensory amplification showed significant small to moderate associations with pain catastrophizing and also with pain and disability. After controlling for the above mentioned psychological variables, catastrophizing still yielded an independent contribution to the explanation of variance in pain and disability parameters. Conclusions: The PCS-C in its German form is a valid and reliable instrument for assessing catastrophizing in children with recurrent pain, in particular headache, in the age of 10–16 years. Pain catastrophizing is suggested to be assessed especially in pediatric pain patients as it is a significant moderator of pain and disability. In children with a distinct tendency to catastrophize cognitive restructuring should become a target of pediatric pain therapy, as a reduction of catastrophizing cognitions may indirectly help to ameliorate pain and disability.
Aim: The Material Values Scale is an instrument to assess beliefs about the importance to own material things. This instrument originally consists of the three subscales: ‘centrality’, ‘success’, and ‘happiness’. The present study investigated the psychometric properties of the German version of the MVS (G-MVS). Method: A population-based sample of 2,295 adult Germans completed the questionnaire in order to investigate the factorial structure. To test construct validity, additional samples were gathered among patients with compulsive buying (N=52) and medical students (N=347) who also answered the Compulsive Buying Scale (CBS) and the Patient Health Questionnaire depression scale (PHQ-8). Results: In the German population-based sample we could not confirm the 3-factor model but rather suggest a 2-factor solution with a first collapsed factor ‘centrality/success’, and the second factor ’happiness’. Patients with compulsive buying showed the highest scores on the G-MVS. While G-MVS scores among compulsive buyers and medical students were significantly related to compulsive buying scores, the correlation between the G-MVS and the depression measure appeared substantially lower. We did not find any gender differences regarding materialism, neither in the population-based sample nor in the students’ or compulsive buyers’ samples. However, age was negatively related to G-MVS scores. Conclusion: Confirmatory factor analyses suggest a 2-factor model of the G-MVS. Overall, the results indicate the use of the G-MVS as a brief, psychometrically sound, and potentially valid measure for the assessment of material values.
OBJECTIVE:This pilot study examined the extent to which a specific mechanism of emotion regulation - namely, ambivalence concerning the expressiveness of German soldiers' emotions - affects the severity of PTSD symptoms after a military operation.METHODOLOGY:A survey was conducted at three points in time among 66 soldiers deployed on military crisis operations. The Harvard Trauma Questionaire (HTQ), the Ambivalence over Emotional Expressiveness Questionnaire (AEQ-G18), and a questionnaire on the particular stress of German soldiers during military operations were used.RESULTS:The study showed a significant correlation between emotional ambivalence and traumatization. Furthermore, it was shown that the subjective stress of soldiers leading up to deployment is more pronounced when emotional ambivalence is stronger in the context of military operations. This particular stress is greater before and during the military operation than after. Compared to a male control sample, the average AEQ-G18 scores of the soldier sample examined here are considerably lower.CONCLUSION:This pilot study clearly indicates that the AEQ-G18 could be a suitable predictor of the psychological burden on soldiers. The correlations between emotional ambivalence on the one hand and the particular and post-traumatic stressors on the other hand are not only statistically significant in the present pilot study, but may also be relevant as risk factors. It is, therefore, necessary to conduct more extensive studies on soldiers participating in military operations to verify the results of this pilot study.
Aim: Trust is an essential element in physician-patient interaction fostering in general adherence and improving patient- and physician-reported outcomes. Regarding severely injured patients, trust-building behaviour is important because of the severity of injuries and therefore potential associated physical and psychological consequences. The objective of this study was to identify significant and relevant determinants on trust of severely injured patients in their physicians in surgical intensive care units. Methods: Ninety-one severely injured patients completed a self-administered questionnaire after being transferred from surgical intensive care unit to surgical unit. All patients were treated in four hospitals of maximal care in North Rhine-Westphalia between 2001 and 2005. To assess different aspects of trust the “trust in physician” scale of the Cologne Patient Questionnaire (CPQ) was used. “Psychosocial care by physicians” is measured through: support, devotion, information and shared-decision making provided by physicians. Patient- and trauma related control variables are also included in a logistic regression model. Results: Stepwise logistic regression identified “psychosocial care provided by physicians” as a significant contributor to severely injured patients’ trust (Nagelkerke’s R2: 41%). “Trust in physicians” is correlated with all four dimensions of “psychosocial care by physicians”: support (0.546), devotion (0.443), information (0.396), and shared-decision making behaviour (0.342) provided by physicians in surgical intensive care units. Conclusions: This finding confirms the importance of supportive communication style in physician-patient interaction concerning reported trust of severely injured patients on surgical intensive care units. Medical education should integrate sound knowledge about psychosocial aspects of interaction to provide effective emotional and informational support to build up and maintain patient trust.
Physical Therapy (PT) and self-help groups (SHG) are important components of health care in rheumatic diseases. The utilisation of PT and SHG by patients with rheumatic diseases may be influenced by several factors. The aim of this study is to summarize the evidence on PT and SHG utilisation of patients with rheumatic diseases in Germany. We systematically searched the MEDLINE-database for studies that evaluated the utilisation and factors that possibly influence the utilisation of PT and SHG. Eight studies were found for PT-utilisation and one for SHG-utilisation. Between 25 and 59 percent of patients with rheumatic diseases received PT services. Several individual and contextual factors that may influence the utilisation could be identified. In conclusion, evidence exists for wide variations in the utilisation of PT services and an underuse of such services among patients with rheumatic diseases in Germany. By contrast, little evidence exists on the utilisation of SHG.
Background: The large-scale representative population surveys conducted by Germany’s Robert Koch Institute (RKI) contain questions pertaining to health and its determinants as well as the prevalence and frequency of outpatient services utilization. The same holds for the Socioeconomic Panel (SOEP, Sozio-ökonomisches Panel) and the Bertelsmann Healthcare Monitor (Gesundheitsmonitor) surveys. The purpose of this study is to examine the comparability of the instruments used in these surveys and their results. Methods: The questions on outpatient care utilization examined in this study were taken from the public use files of the East-West Health Survey (Ost-West Survey; OW1991), the 1998 Federal National Health Survey (Bundesgesundheitssurvey; BGS1998), the 2003 Telephone Health Survey (TEL2003), and the 2009 German Health Update (Gesundheit in Deutschland aktuell GEDA2009). The study also used data from the 26 waves of the SOEP (1984–2009) and the 16 waves of the Bertelsmann Healthcare Monitor (2001–2009) studies. Results: In the OW1991 and the BGS1998, questions on outpatient services utilization differ by the types of physicians inquired about. The four-week prevalence of contact with general practitioneers (GP) was 29% in the OW1991; the twelve-month prevalence in the BGS1998 was 69%. The OW1991 and the BGS1998 also surveyed participants on the number of physician contacts made during those reference periods (average number of contacts: 1.8 over the previous four weeks (OW1991) and 4.9 over the previous 12 months (BGS1998)). The TEL2003 inquires into the three-month prevalence of contact with private practice physicians in general (63%) as well as the number of contacts with primary care physicians over the previous twelve months (88% with at least one contact, average number of contacts: 4.6, range: 1–92). In the GEDA2009 survey, 88% of participants reported having contacted a physician at least once over the previous twelve months and an average of 6.1 contacts with all physicians working under contract with the German statutory health insurance (SHI) funds. The 2009 SOEP survey revealed a 28% three-month prevalence of contact with all types of physicians and an average of 3.6 contacts (among participants who had made at least one contact during this period). According to the Bertelsmann Health Monitor, the twelve-month prevalence of contact with GPs was 82%, with the average number of contacts being 5.0. The Bertelsmann Health Monitor also surveys participants on contacts made with four other types of physicians; the OW1991 and the BGS1998 ask about contacts made with over ten different types of physicians when examining the frequency of services use. Conclusions: Not only do the target groups of the RKI surveys, the SOEP and the Bertelsmann Health Monitor differ; their questions on outpatient care utilization also differ in terms of examined reference period and types of physicians contacted by survey participants, question wording including clarifications (e.g., asking the participant to also consider contacts not made “in person” with physicians when answering a question), and response categories. Therefore, unlike the results of the surveys’ questions on inpatient care, the results of questions on the use of outpatient care services are not easily comparable, even those regarding contact with primary care physicians and GPs. The results of secondary analyses of German SHI claims data could be used to confirm the external validity of the surveys’ results.
AIMS AND OBJECTIVES:Heatwaves can pose a severe threat to health, especially to older people. However, warnings do not necessarily lead to preventive action. This study aims at exploring individual risk perception and adaptive measures of older people and their carers. Their views are explored, taking into account personal backgrounds.METHODS:Questionnaire-based interviews were administered to 20 men and women (64-94 years, living in their own homes or nursing homes) and 13 carers. A qualitative analysis following a framework approach was performed.RESULTS:The majority of respondents stated that older people might be compromised by heatwaves; however, a large proportion of respondents saw themselves as less affected than the average population. Most respondents adopted preventive measures during heatwaves and a majority received warnings or pieces of information. The role of general practitioners in direct warning situations was judged controversial. Survey respondents displayed resistance to the use of technical devices to monitor potentially dangerous situations. In addition, the results support many previous findings. In particular, the relative concepts of ageing, variety of information channels used, and control orientations could be confirmed.CONCLUSIONS:General practitioners hold a position of trust and play a central role in the promotion of preventive action, but there are also limitations to their outreach. Many respondents could be classified as socially active, which has implications for preventive information campaigns. Information campaigns using different channels and targeting a larger audience should be considered. The degree of information of carers can partly be improved.
BACKGROUND:The following analysis aims to determine whether differences in the use of prevention and health promotion services in Germany can be attributed to health inequality between different social status groups measured by education, occupation and income and where certain improvements can be made in health promotion and prevention efforts and research to reduce those differences.METHODS:A systematic literature search was conducted using MedPilot to identify relevant articles published between 1998 and 2010 in the Medline, Medizinische Gesundheit, CC Med, Deutsches Ärzteblatt and Sozialmedizin (SOMED) databases, the Hogrefe, Karger, Krause and Pachermegg and Thieme publisher databases, the Cochrane Database of Systematic Reviews (CDSR), the Cochrane Database of Abstracts of Reviews of Effectiveness (DARE), and the Cochrane Central Register of Controlled Trials.RESULTS:A total of 23 empirical studies on the topic of "prevention, health prevention and social inequality" met the criteria for inclusion in the review. 20 of the 23 reviewed studies provided relatively clear evidence of a significant association between higher social status and greater use of prevention and health promotion services. According to the reviewed studies, gender tends to have a greater effect on the use of prevention and health promotion services than characteristics of vertical social inequality. No studies were found dealing with tertiary prevention or using qualitative methods to explore their research questions.CONCLUSIONS:Overall, the review shows that there is sufficient evidence for the relationship between social status and the use of prevention and health promotion services and that this association is both significant and relevant. There are, however, a few "blind spots" in research on this topic, such as a lack of studies on tertiary prevention, especially with regards to prevention and health promotion services use among men, as well as general studies on health promotion among men and women. There is also a lack of published intervention studies demonstrating how to better reach the socially disadvantaged.
OBJECTIVES:As in nearly all European countries, demographic developments in Germany have led to both a relative and an absolute increase in the country's elderly population. The care and support needed by these people is primarily provided by relatives or friends and close acquaintances within the home environment. The major challenges for society are to sustain, promote and support these informal resources. In order to achieve this, it is crucial that family caregivers are provided with situation-specific services that support them and relieve their burden of care. The major challenges for society are therefore to sustain, promote and support informal resources and to provide the opportunity for the use of services aimed at assisting and relieving the burden of family caregivers.METHODS:In the context of the EUROFAMCARE study, 1,003 family caregivers from Germany were interviewed at home about their experiences using a standardized questionnaire. Included in the study were primary caregivers providing at least four hours of personal care or support per week to a relative aged 65 years or older. Subjects solely providing financial support were excluded. In this paper, a linear regression analysis has been conducted to analyse impact of sociodemographic factors on the utilisation of support services.RESULTS:The family caregivers were 54 years on average (SD=13.4), 76% of them were female. The dependent elderly were 80 years on average (SD=8.3), and 69% of them were women. 60% of them were receiving long-term care insurance benefits. Use of support services aimed directly at family caregivers is very low. After including certain services aimed primarily at those in need of care but also often serving as a source of relief for family caregivers, the percentage of caregivers using support services increased slightly. Among sociodemographic characteristics, caregivers' gender and education level have the greatest influence on services use. Other influential factors are caregivers' perception of their caregiving burden and their assessment of the dependent family member's need for assistance and support.
OBJECTIVE:This systematic review aims to assess the use and implementation of the Behavioral Model of Health Services Use developed by Ronald M. Andersen in recent studies explicity using this model.METHODS:A systematic search was conducted using PubMed in April 2011. The search strategy aimed to identify all articles in which the Andersen model had been applied and which had been published between 1998 and March 2011 in English or German. The search yielded a total of 328 articles. Two researchers independently reviewed the retrieved articles for possible inclusion using a three-step selection process (1. title/author, 2. abstract, 3. full text) with pre-defined inclusion and exclusion criteria for each step. 16 studies met all of the inclusion criteria and were used for analysis. A data extraction form was developed to collect information from articles on 17 categories including author, title, population description, aim of the study, methodological approach, use of the Andersen model, applied model version, and main results. The data collected were collated into six main categories and are presented accordingly.RESULTS:Andersen's Behavioral Model (BM) has been used extensively in studies investigating the use of health services. The studies identified for this review showed that the model has been used in several areas of the health care system and in relation to very different diseases. The 1995 version of the BM was the version most frequently applied in the studies. However, the studies showed substantial differences in the variables used. The majority of the reviewed studies included age (N=15), marital status (N=13), gender/sex (N=12), education (N=11), and ethnicity (N=10) as predisposing factors and income/financial situation (N=10), health insurance (N=9), and having a usual source of care/family doctor (N=9) as enabling factors. As need factors, most of the studies included evaluated health status (N=13) and self-reported/perceived health (N=9) as well as a very wide variety of diseases. Although associations were found between the main factors examined in the studies and the utilization of health care, there was a lack of consistency in these findings. The context of the studies reviewed and the characteristics of the study populations seemed to have a strong impact on the existence, strength and direction of these associations.CONCLUSIONS:Although the frequently used BM was explicitly employed as the theoretical background for the reviewed studies, their operationalizations of the model revealed that only a small common set of variables was used and that there were huge variations in the way these variables were categorized, especially as it concerns predisposing and enabling factors. This may stem from the secondary data sets used in the majority of the studies, which limited the variables available for study. Primary studies are urgently needed to enrich our understanding of health care utilization and the complexity of the processes shown in the BM.
Objectives: To test the effects of body weight maintenance, gain, and loss on health care utilisation in terms of outpatient visits to different kinds of physicians in the general adult population. Methods: Self-reported utilisation data were collected within two population-based cohorts (baseline surveys: MONICA-S3 1994/95 and KORA-S4 1999/2001; follow-ups: KORA-F3 2004/05 and KORA-F4 2006/08) in the region of Augsburg, Germany, and were pooled for present purposes. N=5,147 adults (complete cases) aged 25 to 64 years at baseline participated. Number of visits to general practitioners (GPs), internists, and other specialists as well as the total number of physician visits at follow-up were compared across 10 groups defined by body mass index (BMI) category maintenance or change. Body weight and height were measured anthropometrically. Hierarchical generalized linear regression analyses with negative binomial distribution adjusted for sex, age, socioeconomic status (SES), survey, and the need factors incident diabetes and first cancer between baseline and follow-up were conducted. Results: In fully adjusted models, compared to the group of participants that maintained normal weight from baseline to follow-up, the following groups had significantly higher GP utilisation rates: weight gain from normal weight (+36%), weight loss from preobesity (+39%), maintained preobesity (+34%), weight gain after preobesity (+43%), maintained moderate obesity (+48%), weight gain from moderate obesity (+107%), weight loss from severe obesity (+114%), and maintained severe obesity (+83%). Regarding internists, those maintaining moderate obesity reported +107% more visits; those with weight gain from moderate obesity reported +91%. The latter group also had +41% more consultations with other physicians. Across all physicians, mean number of visits were estimated at 7.8 per year for maintained normal weight, 9 for maintained preobesity, 11 for maintained moderate obesity, and 12 for maintained severe obesity. Among those with weight loss, the mean number of visits were 8.7, 10.6 and 10.8 for baseline preobesity, moderate obesity, and severe obesity, respectively. Finally, those with weight gain from normal weight and preobesity reported 9.4 and 9.3 visits, respectively, and those with baseline moderate and follow-up severe obesity reported 13.1 visits (the most overall). Women reported higher GP and other physician utilisation. While all utilisation rates increased with age, GP utilisation was lower in middle to high SES groups. Conclusion: Compared to maintained normal weight over a 7- to 10-year period, maintained overweight, weight gain and weight loss are associated with higher outpatient physician utilisation in adults, especially after baseline obesity. These effects only partly became insignificant after inclusion of incident diabetes or first cancer into the model. Future research should further elucidate the associations between weight development and health care utilisation by BMI status and the mechanisms underlying these associations.
Recent national and international socio-epidemiological research has consistently demonstrated a significant social gradient in health-related quality of life, morbidity andmortality, favoring the higher and disadvantaging the lower social status groups. This holds true both for Germany and Europe in general as well as for other industrialized countries such as USA or Canada. For instance, in Germany differences in life expectancy between top and lowest income groups range up to 10 years. Against this background, a crucial scientific and political question is whether the health care system inor decreases this gap. First research findings in Germany indicate that the gap might be influenced more by differences in utilization than in supply. In 2002, the working group “Health Care Research” was founded within the German Association of Medical Sociology (Deutsche Gesellschaft fur Medizinische Soziologie, DGMS), consisting of about 30 scientists. In the following years, several workshops at national and international conferences were held by members of this group. In 2007, a first book resulted from this collaboration, which was published by Juventa and presentedmedical sociological health care research in its full scope [1]. Subsequently, the special importance of utilization of health care triggered a proposal to the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) for funding a scientific network on “Health care utilization in Germany”. After its approval (grant no.: JA-1849, 1-1), the network started off under the designation of NWIn Research Network (NWIn: “Netzwerk Inanspruchnahme”, i.e. “Utilization Network”) in January 2010 for a three years funding period. In 2013, a book publication provisionally entitled “Health care utilization in Germany: theory, methodology, and outcomes” is scheduled to be published by Springer Science + Business Media. As one of its key features, all chapters of this edited book will relate to one and the same theoretical approach, namely one (if not the) internationally leading framework for utilization research: the Behavioral Model of Health Care Utilization (BM) by US medical sociologist and health services researcher Ronald M. Andersen [2], [3]. Prior to this book publication, we are happy to present for the NWIn Research Network this special issue of GMS Psycho-Social-Medicine (P-S-M). In the first of six contributions, Birgit Babitsch, Daniela Gohl and Thomas von Lengerke via a systematic review assess the explicit use of Andersen’s BM in studies conducted in Europe or Anglo-American countries and published between January 1998 and March 2011 [4]. Although associations of higher utilization were found with older age, being a woman, higher income and poorer health, there were several inconsistencies across studies, among others that the operationalizations of the model revealed that only a small common set of variables was used, and that there were huge variations in the way these variables were categorized, especially in regard to predisposing and en-
Objective: Social support is an important element of family medicine within a primary care setting, delivered by general practitioners and practice nurses in addition to usual clinical care. The aim of the study was to explore general practitioner’s, practice nurse’s and people with type 2 diabetes’ views, experiences and perspectives of the importance of social support in caring for people with type 2 diabetes and their role in providing social support. Methods: Interviews with general practitioners (n=10) and focus groups with practice nurses (n=10) and people with diabetes (n=9). All data were audio-recorded, fully transcribed and thematically analysed using qualitative content analysis by Mayring. Results: All participants emphasized the importance of the concept of social support and its impacts on well-being of people with type 2 diabetes. Social support is perceived helpful for people with diabetes in order to improve diabetes control and give support for changes in lifestyle habits (physical activity and dietary changes). General practitioners identified a lack of information about facilities in the community like sports or self-help groups. Practice nurses emphasized that they need more training, such as in dietary counselling. Conclusions: Social support given by general practitioners and practice nurses plays a crucial role for people with type 2 diabetes and is an additional component of social care. However there is a need for an increased awareness by general practitioners and practice nurses about the influence social support could have on the individual’s diabetes management.
