Association of generalized anxiety symptoms and panic with health care costs in older age-Results from the ESTHER cohort study

BACKGROUND

Little is known specifically about the association between generalized anxiety symptoms or panic and health care costs in older age. The aim of this study was to examine the association between generalized anxiety symptoms, panic and health care costs in people aged 65 and over.

METHODS

Cross-sectional data from the 8-year follow-up of a large, prospective cohort study, the ESTHER study, was used. Individuals aged 65 and over, who participated in the study's home assessment, were included in this analysis (n = 2348). Total and sectoral costs were analyzed as a function of either anxiety symptoms, probable panic disorder, or a panic attack, while controlling for selected covariates, using Two Part and Generalized Linear Models. Covariates were chosen based on Andersen's Behavioral Model of Health Care Use.

RESULTS

There was no significant association between either of the anxiety or panic measures and total health care costs. Stratified by health care sectors, only the occurrence of a panic attack was significantly associated with incurring costs for outpatient non-physician services (OR: 1.99; 95% CI: 1.15-3.45) and inpatient services (OR: 2.14; 95% CI: 1.07-4.28). Other illness-related factors, such as comorbidities and depressive symptoms, were associated with health care costs in several models.

LIMITATIONS

This was a cross-sectional study relying on self-reported data.

CONCLUSION

This study points to an association between a panic attack and sector-specific health care costs in people aged 65 and over. Further research, especially using longitudinal data, is needed.

Unterschiede in der Morbidität nach Krankenversichertenstatus im Alter

Ziel der Studie: Es fehlen bislang Studien, die Morbiditätsunterschiede zwischen GKV und PKV in der älteren Bevölkerung untersuchen. Ziel dieser Studie ist es daher, Unterschiede in der Morbidität zwischen den Versicherten der GKV und PKV im Alter aufzudecken.

Methodik: Es wurden Daten von 2 Follow-Up-Wellen mit einem Abstand von 3 Jahren herangezogen. Diese basieren auf einer bevölkerungsbezogenen Kohortenstudie (ESTHER Studie) im Saarland. Die Morbidität wurde durch Hausarztangaben mit einem generischen Instrument (Cumulative Illness Rating Scale for Geriatrics) erfasst. Zur Schätzung wurde der Between-Schätzer herangezogen, der ausschließlich die Variation zwischen den Individuen quantifiziert. Dabei wurde im Basismodell neben dem Versichertenstatus für das Geschlecht und das Alter kontrolliert. In weiteren Modellen wurde sukzessive ebenfalls für Schulbildung, den Familienstand und das Einkommen kontrolliert.

Ergebnisse: Während in den Spezifikationen ohne Berücksichtigung des Einkommens beträchtliche Unterschiede in der Morbidität zwischen PKV- und GKV-Versicherten erkennbar waren, mindert sich dieser Effekt unter Kontrolle des Einkommens stark und war bei Männern nicht mehr signifikant.

Schlussfolgerung: Zu einem bedeutenden Teil können existierende Morbiditätsunterschiede zwischen Versicherten der GKV und PKV durch Einkommensunterschiede zwischen den beiden Gruppen erklärt werden. Dies zeigt die große Bedeutung der Ausgestaltung des Modells bei der Untersuchung von Morbiditätsunterschieden zwischen GKV und PKV auf.

The GALAD scoring algorithm based on AFP, AFP-L3, and DCP significantly improves detection of BCLC early stage hepatocellular carcinoma

Background: Hepatocellular carcinoma (HCC) is one of the leading causes of death in cirrhotic patients worldwide. The detection rate for early stage HCC remains low despite screening programs. Thus, the majority of HCC cases are detected at advanced tumor stages with limited treatment options. To facilitate earlier diagnosis, this study aims to validate the added benefit of the combination of AFP, the novel biomarkers AFP-L3, DCP, and an associated novel diagnostic algorithm called GALAD. Material and methods: Between 2007 and 2008 and from 2010 to 2012, 285 patients newly diagnosed with HCC and 402 control patients suffering from chronic liver disease were enrolled. AFP, AFP-L3, and DCP were measured using the µTASWako i30 automated immunoanalyzer. The diagnostic performance of biomarkers was measured as single parameters and in a logistic regression model. Furthermore, a diagnostic algorithm (GALAD) based on gender, age, and the biomarkers mentioned above was validated. Results: AFP, AFP-L3, and DCP showed comparable sensitivities and specifities for HCC detection. The combination of all biomarkers had the highest sensitivity with decreased specificity. In contrast, utilization of the biomarker-based GALAD score resulted in a superior specificity of 93.3 % and sensitivity of 85.6 %. In the scenario of BCLC 0/A stage HCC, the GALAD algorithm provided the highest overall AUROC with 0.9242, which was superior to any other marker combination. Conclusions: We could demonstrate in our cohort the superior detection of early stage HCC with the combined use of the respective biomarkers and in particular GALAD even in AFP-negative tumors.

[Which Factors Affect Out-of-pocket Payments for Health Care Services Among Elderly Germans? Results of a Longitudinal Study]

Background: In Germany, out-of-pocket payments (OOPP) account for a large proportion of total health expenditure. However, there are only few investigations on how morbidity-related, sociodemographic and lifestyle factors affect OOPP particularly in the older population. The aim of this study was to identify factors affecting OOPP for health care services among elderly Germans in a longitudinal setting. Methods: This longitudinal study used data from 2 follow-up waves (3-year interval) from a population-based prospective cohort study (ESTHER study) collected in Saarland, Germany. At the first follow-up wave, subjects were between 57 and 84 years old. Participants provided comprehensive data including individual OOPP for the preceding 3 months. Fixed effects (FE) regressions were used to determine factors affecting OOPP. Results: Mean individual OOPP (3-month period) rose from € 119 (first wave) to € 136 (second wave). Longitudinal regressions showed that higher morbidity did not affect OOPP. Moreover, changes in sociodemographic as well as lifestyle factors were not related to changes in OOPP. Solely, exemption of OOPP reduced the dependent variable significantly. Conclusion: In contrast to cross-sectional findings for Germany, OOPP are not related to morbidity and income in this study. This underlines the complex nature of OOPP in old age and the need for longitudinal studies to gain some insight into the underlying causal factors.

Net costs of dementia by disease stage

OBJECTIVE

To estimate net costs of dementia by degree of severity from a societal perspective, including a detailed assessment of costs of formal and informal nursing care.

METHOD

In a cross-sectional study, costs of illness were analysed in 176 dementia patients and 173 matched non-demented control subjects. Healthcare resource use and costs were assessed retrospectively by means of a questionnaire. Dementia patients were classified into three disease stages, and linear regression models were applied to estimate net costs of dementia by degree of severity.

RESULTS

Annual net costs of dementia by stage were approximately €15 000 (mild), €32 000 (moderate) and €42 000 (severe), corresponding to US-$21 450, 45 760 and 60 060 respectively. Across disease stages, nursing care accounted for approximately three-quarters of total costs, of which half resulted from informal care. In sensitivity analyses using different valuation methods for nursing care, total costs decreased or increased by more than 20%.

CONCLUSION

Net costs more than double across stages of dementia. Informal care accounts for a considerable share of nursing care costs, and the approach to valuation of informal care has a large impact on cost-of-illness estimates.

[Factors influencing the decision to establish a primary care practice: results from a postal survey of young physicians in Germany]

AIM OF THE STUDY

Although the estimated need for primary health care is covered to 108% in Germany, a primary care physician shortage is emerging in some regions. Moreover, the number of young physicians completing a specialist medical training for general medicine is decreasing. Therefore the present study aimed to investigate factors influencing young physicians to aspire to such a specialist training as well as aspects considered as important for practice establishment by these physicians.

METHODS

14 939 young physicians aged under 40 years without completed specialist medical training were contacted by mail using databases of five state chambers of physicians (Lower Saxony, Westfalen-Lippe, Saxony, Saxony-Anhalt, Mecklenburg-Western Pomerania). The physicians were asked to answer questions regarding socio-demographic characteristics, the aspired medical speciality, their purpose to establish a practice as well as a questionnaire regarding factors which could be important for the latter decision. The questionnaire had been developed based on qualitative interviews with young physicians and an additional literature search. The answers of 5 053 respondents were eligible for data analysis. The questionnaire regarding factors influencing practice establishment was evaluated using a principal component analysis. Variables predicting the decision for a general medicine specialist training and the weighting of different factors for practice establishment were analysed using logistic or linear regression models.

RESULTS

A general medicine specialist training was rather aspired by women, physicians who grew up in rural areas, living with a partner/spouse and having children. No differences were found between physicians living in the Old or New Federal States. Principal component analysis revealed 6 relevant factors for practice establishment. Of these, surrounding conditions for family as well as professional duties (e. g., on-call duty) were most important for the physicians. Opportunities for professional cooperation, working conditions and quality of life in the surrounding area had least importance. On average financial conditions ranged, being for men and physicians without children especially important, but not being influenced by the aspired specialist medical training or the purpose the establish a practice.

CONCLUSIONS

The results point to measures which could be suited for rendering the decision-making in favour of the establishment of a primary care practice by young physicians in rural areas more attractive again.

Urban residence, victimhood and the appraisal of personal safety in people with schizophrenia: results from the European Schizophrenia Cohort (EuroSC)

BACKGROUND

Patients with schizophrenia are at increased risk of being victims of violent and non-violent crimes. We have determined how the experience of crime and subjective feelings of safety differ between urban and rural residential areas.

METHOD

We analysed data from the European Schizophrenia Cohort (EuroSC), a 2-year follow-up study of 1208 patients in the UK, France and Germany. Subjective safety and a history of victimhood were elicited with Lehman's Quality of Life Inventory. Regression models adjusted the effects of living environment for country, education, employment, financial situation, drug and alcohol abuse, criminal arrests and the level of schizophrenic symptoms.

RESULTS

Ten per cent of patients were victims of violent and 19% of non-violent crimes. There was no significant relationship between victim status and residential area. However, subjective safety was clearly worse in cities than in rural areas. Aspects of objective and subjective safety were related to different factors: being the victim of violence was most strongly associated with alcohol and drug abuse and with criminal arrests of the patients themselves, whereas impaired subjective safety was most strongly associated with poverty and victimhood experience.

CONCLUSIONS

Although urban living was not associated with increased objective threats to their security, patients did feel more threatened. Such stress and anxiety can be related to concepts of social capital, and may contribute unfavourably to the course of the illness, reflecting the putative role of appraisal in cognitive models of psychosis. Securing patients' material needs may provide a way to improve subjective safety.

Risk factors for suicidality in Europe: results from the ESEMED study

BACKGROUND

Precise knowledge of the epidemiology of suicidality provides necessary information for designing prevention programs. The aims of the present study were to investigate the prevalence and correlates of suicidal ideas and attempts in the general population of Europe.

METHODS

The European Study on the Epidemiology of Mental Disorders (ESEMED) is a cross-sectional household survey carried out in a probability representative sample of non-institutionalised adults (aged 18 years or older) of six European countries (Belgium, France, Germany, Italy, the Netherlands and Spain). The Composite International Diagnostic Interview (CIDI 3.0) was administered to 21,425 individuals.

RESULTS

Lifetime prevalence of suicidal ideation was 7.8% and of suicidal attempts 1.3%. Being women, younger and divorced or widowed were associated with a higher prevalence of suicide ideation and attempts. Psychiatric diagnoses were strongly related to suicidality. Among them, major depressive episode (Rate ratio 2.9 for lifetime ideas and 4.8 for lifetime attempts), dysthymia (RR 2.0 and 1.6), GAD (RR 1.8 and 2.3 for lifetime), PTSD (RR 1.9 and 2.0) and alcohol dependence (RR 1.7 and 2.5) were the most important. Population attributable risks for lifetime suicidal attempt was 28% for major depression.

LIMITATIONS

Information about suicidal ideas and attempts was self reported, psychiatric diagnoses were made using fully structured lay interviews rather than clinician-administered interviews.

CONCLUSIONS

In spite of meaningful country variation in prevalence, risk factors for suicidality are consistent in the European countries. Population prevention programmes should focus on early diagnosis and treatment of major depression and alcohol abuse and in those individuals with recent appearance of suicidal ideas.

The impact of caregivers' characteristics, patients' conditions and regional differences on family burden in schizophrenia: a longitudinal analysis

OBJECTIVE

Impact of caregiver characteristics, patient variables, and regional differences on family burden.

METHOD

Two hundred and eighteen schizophrenia patients and key-relatives of an urban and a rural area were examined five times over 30 months. Patients' psychopathology, service utilization; relatives' burden, coping abilities and contact duration with the patients were recorded. Effects of interpersonal differences and intrapersonal changes over time were analyzed with regression models.

RESULTS

Interpersonal differences (patients' positive and negative symptoms, relatives' coping abilities, and patient contact) and intrapersonal changes (relatives' coping abilities, patients' negative symptoms and utilization of community care) predicted family burden.

CONCLUSION

Family education programs should help caregivers to improve their coping strategies. Therapy solutions must address negative symptoms just as much as positive symptoms, as these especially impact caregivers. Intensified community-based care can reduce burden, but provision alone is not sufficient. Psychiatrists and caregivers should motivate patients to take advantage of such offers.

Wirksamkeit eines Interventionsprogramms auf die Burnout-Belastung von Lebenspartnern depressiv Erkrankter

AIM OF THE STUDY

A newly developed group intervention programme was evaluated with regard to its effectiveness to decrease the burnout symptoms of the partners of depressed patients.

METHODS

Within a period of six months, a group of 66 persons has taken part in the intervention for a total of twelve group sessions. A control group consisted of 50 persons without any intervention. Burnout was assessed using the German version of the Maslach Burnout Inventory (MBI). To evaluate the time effect, the burnout dimensions were used as independent variables in random effects models.

RESULTS

Over the analyzed period of time no significant positive effect was measured on any of the assessed burnout dimensions.

CONCLUSIONS

An increased inclusion of depressed patients in the intervention as well as an increased intensity and a lowering of the admission threshold for the heavily burdened relatives could increase the effectiveness of the program.

[Development of a screening instrument for heavy users of psychiatric inpatient services]

Patients who show an above-average utilization of medical care are described as "heavy users". Heavy utilization of psychiatric inpatient care could be reduced by well directed community based services. Heavy users should, therefore, be identified at the beginning of a period of heavy service consumption. For this reason, a screening instrument (SPSI) was developed. Six predictors of heavy utilization of inpatient care were included as items in the SPSI. Weighting of items and examination of the instrument were carried out with a sample of 184 schizophrenia patients, whose utilization of inpatient care was recorded prospectively over a period of 30 months. 83 percent of heavy users and 85 percent of ordinary users were correctly identified with the SPSI test at a cutoff score of - 6.7. The SPSI is a short questionnaire which could be used without special rater training in psychiatric care in order to offer identified heavy users well directed community based services, which are less costly than inpatient care, but at least just as appropriate for the special needs of these patients.
