Impact of depersonalization on the course of depression: longitudinal observations from the gutenberg health study.

BACKGROUND: Symptoms of depersonalization (DP) and derealization (DR) are a risk factor for more severe impairment, non-response to various treatments, and a chronic course. In this study, we investigated the effects of DP/DR symptoms in patients with clinically significant depressive symptoms on clinical characteristics and various outcomes in a representative population-based sample with a 5-year follow-up. METHODS: The middle-aged sample comprised n = 10,422 persons at baseline, of whom n = 9,301 were free from depressive and DP/DR symptoms. N = 522 persons had clinically significant depression (PHQ-9 ≥ 10) and co-occurring DP/DR symptoms, and n = 599 persons had clinically significant depression (PHQ-9 ≥ 10) without DP/DR symptoms. RESULTS: There were substantial health disparities between persons with and without depression. These disparities concerned a wide range of life domains, including lower quality of the recalled early life experiences with the parents, current socioeconomic status, social integration (partnership, loneliness), current social and interpersonal stressors (family, work), functional bodily complaints (e.g., tinnitus, migraine, chest pain), unhealthy lifestyle, and the prevalence of already developed physical diseases. These disparities persisted to the 5-year follow-up and were exceptionally severe for depressed persons with co-occurring DP/DR symptoms. Among the depressed persons, the co-occurrence of DP/DR symptoms more than doubled the risk for recurrence or persistence of depression. Only 6.9% of depressed persons with DP/DR symptoms achieved remission at the 5-year follow-up (PHQ-9 < 5). Depression with and without co-occurring DP/DR worsened self-rated physical health significantly. The impact of depression with co-occurring DP/DR on the worsening of the self-rated physical health status was stronger than those of age and major medical diseases (e.g., heart failure). However, only depression without DP/DR was associated with mortality in a hazard regression analysis adjusted for age, sex, and lifestyle. CONCLUSIONS: The results demonstrated that DP/DR symptoms represent an important and easily assessable prognostic factor for the course of depression and health outcomes. Given the low remission rates for depression in general and depression with DP/DR in particular, efforts should be made to identify and better support this group, which is disadvantaged in many aspects of life.

Refined atrial fibrillation screening and cost-effectiveness in the German population.

OBJECTIVE: Little is known on optimal screening population for detecting new atrial fibrillation (AF) in the community. We describe characteristics and estimate cost-effectiveness for a single timepoint electrocardiographic screening. METHODS: We performed a 12-lead ECG in the German population-based Gutenberg Health Study between 2007 and 2012 (n=15 010), mean age 55±11 years, 51% men and collected more than 120 clinical and biomarker variables, including N-terminal pro B-type natriuretic peptide (Nt-proBNP), risk factors, disease symptoms and echocardiographic variables. RESULTS: Of 15 010 individuals, 466 (3.1%) had AF. New AF was found in 32 individuals, 0.2% of the total sample, 0.5% of individuals aged 65-74 years and predominantly men (86%). The classical risk factor burden was high in individuals with new AF. The median estimated stroke risk was 2.2%/year, while risk of developing heart failure was 21% over 10 years. In the 65-74 year age group, the cost per quality-adjusted life-year gained resulting from a single timepoint screening was €30 361. In simulations, the costs were highly sensitive to AF detection rates, proportion of treatment and type of oral anticoagulant. Prescreening by Nt-proBNP measurements was not cost-effective in the current setting. CONCLUSIONS: In our middle-aged population cohort, we identified 0.2% new AF by single timepoint screening. There was a significant estimated risk of stroke and heart failure in these individuals. Cost-effectiveness for screening may be reached in individuals aged 65 years and older. The simple age cut-off is not improved by using Nt-proBNP as a biomarker to guide a screening programme.

Hearing Loss and Its Burden of Disease in a Large German Cohort-Hearing Loss in Germany.

OBJECTIVES/HYPOTHESIS: Hearing loss is the most common sensory impairment worldwide. It restricts patients in many aspects of their daily lives and can lead to social exclusion. Understanding this burden is a mandatory requirement for the care of those affected. Therefore, the aim of this study was to estimate the burden of hearing loss in a large German cohort. STUDY DESIGN: Cohort study. METHODS: The Gutenberg Health Study is designed as a single-center, prospective, and observational cohort study and representative for the city of Mainz, Germany, with its district. Participants were interviewed concerning common otologic symptoms and tested by pure-tone audiometry. The primary outcome was hearing impairment stratified by age and sex. The prevalence of tinnitus was estimated for a subcohort to calculate disability-adjusted life years (DALYs). All results were weighted by the European Standard Population (ESP) 2013. RESULTS: A total of 5,024 participants (mean age: 61.2 years, 2,591 men and 2,433 women) were included in the study. Hearing impairment showed the following prevalence: 28.2% (95% confidence interval [CI], 26.9%-29.4%) mild impairment, 10.1% (95% CI, 9.3%-11.0%) moderate impairment, 2.3% (95% CI, 1.9%-2.7%) moderately severe impairment, 0.2% (95% CI, 0.1%-0.4%) severe impairment, 0% (95% CI, 0.0%-0.1%) profound impairment, and 0.1% (95% CI, 0.0%-0.2%) complete impairment. Weighted for the ESP 2013 (all ages), hearing impairment across all levels (with/without tinnitus) causes a total of 2,118.97 DALYs per 100,000. CONCLUSION: With 40.9% affected, the hearing loss represents a relevant burden of the German population. Understanding this will provide the basis for future guidelines on how to care for these patients. LEVEL OF EVIDENCE: 2 Laryngoscope, 132:1843-1849, 2022.

Work-life conflict and cardiovascular health: 5-year follow-up of the Gutenberg Health Study.

INTRODUCTION: Work-life conflicts (WLC) may impact health, but few studies prospectively consider the impact of WLC on objective outcomes such as cardiovascular disease. Using data from the Gutenberg Health Study (GHS), we examined if WLC at baseline was associated with an increased five-year incidence of cardiovascular events (myocardial infarct, stroke, atrial fibrillation, peripheral artery disease, coronary artery disease, chronic heart failure, sudden cardiac death). We also considered if WLC was associated with incident hypertension and arterial stiffness and if the effects of WLC on cardiovascular health differ for men and women. METHODS: A working subsample of the 15,010 GHS cohort participants completed the Copenhagen Psychosocial Questionnaire, which included five "work-privacy conflict" questions at baseline and at the five-year follow-up. Relative risks for incident hypertension due to increased WLC at baseline (WLC scores exceeding 60 out of 100) were estimated with Poisson regression in the subgroup of participants without hypertension at baseline (n = 2426). Categories of WLC at baseline and follow-up were also used to examine the risk of hypertension due to chronic/recurrent WLC. In this subgroup, we also examined the association between WLC as a continuous score ranging from 0 to 100 with change to arterial stiffness after five years using linear regression. Hazard ratios were estimated for incident cardiovascular events in a larger subsample of participants without prevalent cardiovascular disease at baseline (n = 3698) using Cox regression. We used various multivariable regression models to adjust for sex, age, socioeconomic status, occupational, household, and cardiovascular risk factors. RESULTS: We found no association between WLC and incident hypertension or increased arterial stiffness. The fully-adjusted relative risk for WLC >60 at baseline and hypertension was 0.93 (95% 0.74-1.17). The risk of hypertension due to chronic/recurrent WLC >60 was increased but not statistically significant (RR = 1.13, 95% CI 0.83-1.54). Overall, hazard ratios for incident cardiovascular events were also not increased. However, stratifying the results by sex resulted in a hazard ratio of 1.47 (95% CI 0.54-3.98) for incident cardiovascular disease among women in the fully adjusted model. CONCLUSIONS: Although our results were not statistically significant, they indicate that WLC is negatively impacting the cardiovascular health of women. While these results need to be confirmed with additional research and a longer follow-up, interventions to prevent WLC will promote health and could be especially beneficial for women.

Type I Diabetes is the Main Cost Driver in Autoimmune Polyendocrinopathy.

CONTEXT: Autoimmune polyendocrinopathy (AP), a chronic complex orphan disease, encompasses at least two autoimmune-induced endocrine diseases. OBJECTIVE: To estimate for the first time total, indirect and direct costs for patients with AP, as well as cost drivers. DESIGN: Cross-sectional cost of illness study. SETTING: Academic tertiary referral center for AP. PATIENTS: 146 consecutive, unselected AP patients. INTERVENTION: Interviews pertaining to patients' socioeconomic situation covered a recall period of 12 months. Both the human capital (HCA) and the friction cost approaches (FCAs) were applied as estimation methods. MAIN OUTCOME MEASURES: Direct and indirect annual costs, and sick leave and medication costs. RESULTS: AP markedly impacts healthcare expenses. Mean overall costs of AP in Germany ranged from €5 971 090 to €29 848 187 per year (HCA). Mean indirect costs ranged from €3 388 284 to €16 937 298 per year (HCA) while mean direct costs ranged from €2 582 247 to €12 908 095/year. Mean direct costs per year were €1851 in AP patients with type 1 diabetes (T1D, 76%) and €671 without T1D, which amounts to additional direct costs of €1209 for T1D when adjusting for concomitant autoimmune disease (95% CI = €1026-1393, P < 0.0001). Sick leave cost estimates for AP patients with T1D exceeded those without T1D by 70% (FCA) and 43% (HCA), respectively. In multiple regression analyses, T1D predicted total and direct costs, medication costs and costs for diabetic devices (all P < 0.001). Overall, AP patients with T1D were 54% (FCA) more expensive than those without T1D. CONCLUSIONS: Public health socioeconomic relevance of AP was demonstrated, with T1D as main cost driver.

Income and education predict elevated depressive symptoms in the general population: results from the Gutenberg health study.

BACKGROUND: Socioeconomic status (SES) has a strong association with depression or physical and mental health in general. However, as SES is a multifaceted construct these associations are not easy to explain. Further, there are several indicators and many studies only investigating two or less indicators at the same time. Therefore, this study aims to analyze the cross-sectional and longitudinal association of three defined SES dimensions (education, occupational position and household net-income) with the occurrence of elevated symptoms of depression relative to the impact of important covariates. METHODS: The study included observational data from 12,484 participants of the Gutenberg Health Study. The outcome was "elevated depressive symptoms" as defined by Patient Health Questionnaire (PHQ-2) ≥ 2 at the 2.5-year follow-up. Regression coefficients were adjusted for baseline covariates (age, sex, partnership, depression, anxiety, medical history of depressive or anxiety disorder and major medical diseases (MMD)) in addition to SES sum score and the three single indicators. We further examined interaction terms of the SES with sex, partnership and major medical diseases. We analyzed the sample stratified by elevated depressive symptoms at baseline, as we expected different trajectories in both subgroups. RESULTS: SES, education and household net-income were lower in the group of persons with PHQ-2 ≥ 2 at baseline, and they predicted the occurrence of PHQ-2 ≥ 2 at 2.5 year follow-up in the group of persons without elevated depressive symptoms at baseline after multivariable adjustment (SES: Odds Ratio (OR) 0.96, 0.95-0.98, p <  0.0001; education: OR 0.96, 0.93-0.99, p = 0.036; household net-income: OR 0.96, 0.92-0.99, p = 0.046) but not in the group of persons with elevated depressive symptoms at baseline. Further, we found that the impact of major medical diseases on the development of elevated depressive symptoms was buffered by high income. In addition, living in a partnership buffered the impact of a low occupational position. CONCLUSIONS: Regarding the SES, the dimensions education and household net-income seem to play the most important role for socioeconomic inequalities in persons in Mid-West Germany with depressive symptoms.

[Prevalence of wearing glasses for children and adolescents in Germany and their ophthalmological care : Results of the nationwide KiGGS baseline survey (2003-2006)]. / Prävalenz des Brillentragens von Kindern und Jugendlichen in Deutschland und deren augenärztliche Versorgung : Ergebnisse der KiGGS-Basiserhebung (2003­2006).

BACKGROUND: Vision-relevant refractive errors in children require regular ophthalmological control examinations. In this study we estimated the prevalence of wearing glasses for children and adolescents in Germany and the frequency of ophthalmological care. METHODS: We analyzed data of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS, baseline survey 2003-2006, N = 17,640). Wearing glasses was documented from the age of 3 years in the examination part. We estimated the prevalence of wearing glasses and investigated the relationship with ophthalmological care during the preceding 12 months. Multivariable logistic regression analysis was used to calculate adjusted odds ratios (OR) and 95% confidence intervals (95%CI). Associations were adjusted for age, gender, socioeconomic status, migration background, residence (East/West Germany), participation in regular pediatric check-ups, and presence of strabismus. RESULTS: The prevalence of wearing glasses was 19.7% (95% CI: 18.8-20.5%) in the age range of 3-17 years. The prevalence was higher in girls (22.1%; 21.0-23.3%) compared to boys (17.3%; 16.3-18.3%) and increased with age up to 29.2% (27.6-30.9%) in the age group 14-17 years. The frequency of ophthalmological care within the last 12 months was 61.6% (59.4-63.8%) for those wearing glasses and 15.2% (14.3-6.2%) for those without glasses. Regression analysis revealed an association between ophthalmological care and wearing glasses (OR = 11.4; 10.1-13.0). CONCLUSION: In Germany, wearing glasses depends on gender and age and almost one third of adolescents already wear glasses. The majority of children and adolescents wearing glasses visit an ophthalmologist once a year.

Is assessment of depression equivalent for migrants of different cultural backgrounds? Results from the German population-based Gutenberg Health Study (GHS).

BACKGROUND: Bearing in mind the multicultural background of a national population, little is known about the measurement invariance across different cultures or ethnicities of frequently used screeners for depression. For this reason, the main objective of the current study is to assess the measurement invariance of the Patient Health Questionnaire (PHQ-9) across groups with different migration backgrounds. METHODS: We provided psychometric analyses (descriptive statistics at item and scale level, reliability analysis, exploratory [EFA] and confirmatory factor analyses [CFA]) comparing a native population with first- and second-generation migrants of the German population-based Gutenberg Health Study with N = 13,973 participants completing the PHQ-9. Furthermore, we conducted measurement invariance analyses among different groups of first-generation migrants. RESULTS: Comparing the native population with first- and second-generation migrants, a higher prevalence for mental distress was found for first generation. Although mean score patterns were similar for all groups, analyses of item loadings among first-generation migrants yielded some variance in patterns pointing out that certain items have a distinct impact on depression for specific groups. With regard to the factorial validity for all groups, EFA and CFA provided evidence for the proposed one latent factor structure of the PHQ-9. Depression assessed by the PHQ-9 turned out to be equivalent from a psychometric perspective across different groups stratified by their migration background. CONCLUSIONS: Overall, results of thorough scale and item analyses, especially multigroup confirmatory analyses, provided support that depression, assessed by the PHQ-9, can be considered as psychometrically equivalent across all analyzed groups.

[Ophthalmologic healthcare utilization of people in need of long-term care : Analyses of health insurance data of the AOK Baden-Württemberg]. / Inanspruchnahme von augenärztlichen Leistungen bei Versicherten mit Pflegebedarf : Analysen anhand von Routinedaten der AOK Baden-Württemberg.

INTRODUCTION: Eye diseases causing visual impairment increase with age. Thus, seeking eye care has a higher probability in older people. In this study, the rate of utilization of outpatient eye care services in Germany was analyzed. The analyses focused on older persons and persons in need of either home-based or facility-based long-term care. METHODS: A descriptive secondary data analysis of health insurance data of the AOK Baden-Württemberg from 2016 was conducted. The study population comprised all insured persons on 1 January 2016. The cohort of older persons (60 years+) was further stratified by the type of care (home-based/facility-based) and the level of care (0-3). The utilization of outpatient eye care services was defined by the reimbursement for an ophthalmologist's provision of service. RESULTS: While 39.3% of the study population 60+ years old sought eye care, the utilization rate was lower among people in need of home-based (33.0%) and facility-based care (19.3%). The utilization rates showed comparable age-dependent patterns, except for persons in need of facility-based care where rates were similar for all age groups. Utilization rates were negatively associated with increasing care levels. Only people with care level 0 showed lower utilization rates than people with care level 1. DISCUSSION: Utilization rates of eye healthcare services among older persons are considerably influenced by the need of long-term care, by the form of care as well as by the level of care.

Efficacy and safety of preoperative IOP reduction using a preservative-free fixed combination of dorzolamide/timolol eye drops versus oral acetazolamide and dexamethasone eye drops and assessment of the clinical outcome of trabeculectomy in glaucoma.

INTRODUCTION: To demonstrate that preoperative treatment for 28 days with topical dorzolamide/timolol is non-inferior (Δ = 4 mm Hg) to oral acetazolamide and topical dexamethasone (standard therapy) in terms of intraocular pressure (IOP) reduction 3 and 6 months after trabeculectomy in glaucoma patients. MATERIALS AND METHODS: Sixty-two eyes undergoing trabeculectomy with mitomycin C were included in this monocentric prospective randomized controlled study. IOP change between baseline and 3 months post-op was defined as the primary efficacy variable. Secondary efficacy variables included the number of 5-fluorouracil (5-FU) injections, needlings, suture lyses, preoperative IOP change, hypertension rate and change of conjunctival redness 3 and 6 months post-op. Safety was assessed based on the documentation of adverse events. RESULTS: Preoperative treatment with topical dorzolamide/timolol was non-inferior to oral acetazolamide and topical dexamethasone in terms of IOP reduction 3 months after trabeculectomy (adjusted means -8.12 mmHg versus -8.30 mmHg; Difference: 0.18; 95% CI -1.91 to 2.26, p = 0.8662). Similar results were found 6 months after trabeculectomy (-9.13 mmHg versus -9.06 mmHg; p = 0.9401). Comparable results were also shown for both groups concerning the classification of the filtering bleb, corneal staining, and numbers of treatments with 5-FU, needlings and suture lyses. More patients reported AEs in the acetazolamide/dexamethasone group than in the dorzolamide/timolol group. DISCUSSION: Preoperative, preservative-free, fixed-dose dorzolamide/timolol seems to be equally effective as preoperative acetazolamide and dexamethasone and has a favourable safety profile.

Influence of Corneal Opacity on Intraocular Pressure Assessment in Patients with Lysosomal Storage Diseases.

AIMS: To investigate an influence of mucopolysaccharidosis (MPS)- and Morbus Fabry-associated corneal opacities on intraocular pressure (IOP) measurements and to evaluate the concordance of the different tonometry methods. METHODS: 25 MPS patients with or without corneal clouding, 25 Fabry patients with cornea verticillata ≥ grade 2 and 25 healthy age matched controls were prospectively included into this study. Outcome measures: Goldmann applanation tonometry (GAT); palpatory assessment of IOP; Goldmann-correlated intraocular pressure (IOPg), corneal-compensated intraocular pressure (IOPcc), corneal resistance factor (CRF) and corneal hysteresis (CH) assessed by Ocular Response Analyzer (ORA); central corneal thickness (CCT) and density assessed with Pentacam. Statistical analysis was performed using linear mixed effect models and Spearman correlation coefficients. The concordance between tonometry methods was assessed using Bland-Altman analysis. RESULTS: There was no relevant difference between study groups regarding median GAT, IOPg, IOPcc and CCT measurements. The limits of agreement between GAT and IOPcc/IOPg/palpatory IOP in MPS were: [-11.7 to 12.1mmHg], [-8.6 to 15.5 mmHg] and [- 5.4 to 10.1 mmHg] respectively. Limits of agreement were less wide in healthy subjects and Fabry patients. Palpatory IOP was higher in MPS than in healthy controls and Fabry patients. Corneal opacity correlated more strongly with GAT, IOPg, CH, CRF, CCT and corneal density in MPS (r = 0.4, 0.5, 0.5, 0.7, 0.6, 0.6 respectively) than in Fabry patients (r = 0.3, 0.2, -0.03, 0.1, 0.3, -0.2 respectively). In contrast, IOPcc revealed less correlation with corneal opacity than GAT in MPS (r = 0.2 vs. 0.4). CONCLUSIONS: ORA and GAT render less comparable IOP-values in patients suffering from MPS-associated corneal opacity in comparison to Fabry and healthy controls. The IOP seems to be overestimated in opaque MPS-affected corneas. GAT, IOPg and biomechanical parameters of the cornea correlate more strongly with the corneal clouding than IOPcc in MPS patients.

Bruch's Membrane Opening-Minimum Rim Width Assessment With Spectral-Domain Optical Coherence Tomography Performs Better Than Confocal Scanning Laser Ophthalmoscopy in Discriminating Early Glaucoma Patients From Control Subjects.

PURPOSE: To compare the diagnostic performance and evaluate diagnostic agreement for early glaucoma detection between a confocal scanning laser ophthalmoscope (CSLO) and a spectral-domain optical coherence tomography (SD-OCT). PATIENTS AND METHODS: Fifty-five eyes of 55 open-angle glaucoma patients and 42 eyes of 42 healthy control subjects were enrolled in this observational, cross-sectional study. All participants underwent comprehensive ophthalmic examination, visual field testing, and optic nerve head and retinal nerve fiber layer imaging by CSLO (HRT3) and SD-OCT (Spectralis OCT). The agreements of categorical classifications were evaluated (κ statistics). Area under receiver operating characteristic curves (AUROC) and sensitivity at 95% fixed specificity were computed. RESULTS: The agreements of HRT3 and Spectralis OCT categorical classifications were fair to moderate (κ ranged between 0.33 and 0.54), except for Moorfields regression analysis of the HRT3 and the OCT global Bruch's membrane opening-minimum rim width (BMO-MRW) (criterion 1 κ=0.63, criterion 2 κ=0.67). The AUROC of OCT global BMO-MRW (0.956) was greater than those of HRT3 cup-to-disc area ratio (0.877, P=0.0063), vertical cup-to-disc ratio (0.872, P=0.0072), and cup area (0.845, P=0.0005). At 95% specificity, Spectralis OCT global BMO-MRW attained a higher sensitivity than HRT3 cup-to-disc area ratio (P<0.001). CONCLUSIONS: The BMO-MRW assessment with SD-OCT performed well in discriminating early glaucoma patients from control subjects and had a better performance than CSLO. The diagnostic classifications of HRT3 and Spectralis OCT may reach good agreement.

The Evonik-Mainz Eye Care-Study (EMECS): Development of an Expert System for Glaucoma Risk Detection in a Working Population.

PURPOSE: To develop an expert system for glaucoma screening in a working population based on a human expert procedure using images of optic nerve head (ONH), visual field (frequency doubling technology, FDT) and intraocular pressure (IOP). METHODS: 4167 of 13037 (32%) employees between 40 and 65 years of Evonik Industries were screened. An experienced glaucoma expert (JW) assessed papilla parameters and evaluated all individual screening results. His classification into "no glaucoma", "possible glaucoma" and "probable glaucoma" was defined as "gold standard". A screening model was developed which was tested versus the gold-standard. This model took into account the assessment of the ONH. Values and relationships of CDR and IOP and the FDT were considered additionally and a glaucoma score was generated. The structure of the screening model was specified a priori whereas values of the parameters were chosen post-hoc to optimize sensitivity and specificity of the algorithm. Simple screening models based on IOP and / or FDT were investigated for comparison. RESULTS: 111 persons (2.66%) were classified as glaucoma suspects, thereof 13 (0.31%) as probable and 98 (2.35%) as possible glaucoma suspects by the expert. Re-evaluation by the screening model revealed a sensitivity of 83.8% and a specificity of 99.6% for all glaucoma suspects. The positive predictive value of the model was 80.2%, the negative predictive value 99.6%. Simple screening models showed insufficient diagnostic accuracy. CONCLUSION: Adjustment of ONH and symmetry parameters with respect to excavation and IOP in an expert system produced sufficiently satisfying diagnostic accuracy. This screening model seems to be applicable in such a working population with relatively low age and low glaucoma prevalence. Different experts should validate the model in different populations.

Problems and perspectives of ophthalmic research in Germany: results from a national survey.

PURPOSE: To identify and describe the most relevant obstacles to carrying out ophthalmic research in Germany. METHODS: Two research methods were used to assess current problems in ophthalmic research. First, 55 expert interviews were conducted with major stakeholders in ophthalmic research, and key problems were identified. An online questionnaire was then sent to 3,080 German ophthalmologists, of whom 927 responded by evaluating the current research situation within ophthalmology in Germany. We devised a score to rank areas of concern by multiplying the responders' rate, ranging between -3 ('I disagree completely') and +3 ('I fully agree'), with the percentage of response frequencies. The maximum possible score was 300. RESULTS: The lack of opportunities to combine clinical work and research (score: 231.8) as well as unattractive career perspectives (175.7) were identified as the most relevant problems. Further barriers were difficulties in acquiring research funds (155.7), organizational problems at the local level (143.7) and a lack of support for women (24.1; among women: 122.3). Potential improvement was expected in particular from exemption from clinical work for scientific purposes; this was found to be more appealing than more prestigious awards for research achievements. A widely held position was that research projects should focus more closely on common eye diseases, and that vision research needs a more prominent profile among politicians and in the public arena. CONCLUSION: Our findings may help to initiate improvements in both research performance and outcomes.

Direct cost and predictive factors for treatment in patients with ocular hypertension or early, moderate and advanced primary open-angle glaucoma: the CoGIS study in Germany.

BACKGROUND: The main objectives of this analysis were to assess the treatment costs and to identify major cost drivers and factors predicting direct costs in German patients with ocular hypertension (OHT) or primary open-angle glaucoma (POAG). METHODS: This non-interventional cross-sectional study was conducted in two university hospitals and 13 ophthalmology practices in Germany regions (Bavaria, Rhineland-Palatinate, North Rhine-Westphalia, Hamburg and Mecklenburg-Western Pomerania) between May 2009 and January 2010 to assess resource utilisation in patients with OHT (ICD-10: 40.0) or POAG (ICD-10: 40.1) at early, moderate or advanced stages, according to the European Glaucoma Society classification Guidelines. Treatment patterns and direct costs were evaluated retrospectively for 5 years. Resource utilisation data (medication, hospitalisation, outpatient surgery, visits to ophthalmologists) were abstracted from the charts, and unit costs were applied to estimate direct costs per year (in Euros, 2009), calculated from the perspective of the statutory health insurance in Germany (Gesetzliche Krankenversicherung). Factors predicting costs were assessed in multivariate regression analysis. RESULTS: One hundred and fifty-four patients (17.5% OHT, 27.9% early, 22.7% moderate, and 31.8% advanced POAG), on average 67 years old (SD 11) were included in the study. Average total annual direct costs per patient for OHT were 226 (SD 117), for early POAG 423 (SD 647), moderate 493 (SD 385) and advanced POAG 809 (SD 877). Glaucoma-related medications and hospitalisation represented the two major components of direct costs, increasing with the progression of glaucoma. In addition to treatment switches (p = 0.0001), factors predictive of an increase in total direct costs included the number of hospital interventions (p < 0.0001), disease-state changes since the start of treatment (p = 0.05), and current disease state (p = 0.05). CONCLUSIONS: Direct costs of treatment are higher in glaucoma compared to OHT and further increase in more severe glaucoma states. Additional treatment changes are major contributing factors to the increased treatment costs of glaucoma. If intraocular pressure can be controlled over the long term, progression to moderate and advanced states avoided, and patients remain on initial treatments, treatment costs could decline due to reduced and less expensive healthcare resource utilisation.

Public health relevance of Graves' orbitopathy.

CONTEXT: Disfiguring proptosis and functional impairment in patients with Graves' orbitopathy (GO) may lead to impaired earning capacity and to considerable indirect/direct costs. OBJECTIVE: The aim of the study was to investigate the public health relevance of GO. DESIGN AND SETTING: This cross-sectional study was performed between 2005 and 2009 at a multidisciplinary university orbital center. PATIENTS: A total of 310 unselected patients with GO of various degrees of severity and activity participated in the study. INTERVENTIONS: We conducted an observational study. MAIN OUTCOME MEASURES: We measured work disability and sick leave as well as the resulting indirect/direct costs of GO-specific therapies. RESULTS: Of 215 employed patients, 47 (21.9%) were temporarily work disabled, and 12 (5.6%) were permanently work disabled. Five (2.3%) had lost their jobs, and nine (4.2%) had retired early. The mean duration of sick leave was 22.3 d/yr. Compared with the German average of 11.6 d/yr, 32 (15%) patients had taken longer sick leaves. The duration of sick leave correlated with the disease severity (P = 0.015), and work disability correlated with diplopia (P < 0.001). Multivariable analysis identified diplopia as the principal predictor for work disability (odds ratio, 1.7; P < 0.001). The average costs due to sick leave and work disability ranged between 3,301€ (4,153$) and 6,683€ (8,407$) per patient per year. Direct costs were 388 ± 56€ (488 ± 70$) per patient per year and per year were higher in sight-threatening GO (1,185 ± 2,569€; 1,491 ± 3,232$) than in moderate-to-severe (373 ± 896€; 469 ± 1,127$; P = 0.013) or in mild GO (332 ± 857€; 418 ± 1,078$; P = 0.016). Total indirect costs ranged between 3,318€ (4,174$) (friction cost method) and 6,738€ (8,476$) (human capital approach). Work impairment as well as direct and indirect costs of GO significantly correlated with the scores of the internationally standardized and specific GO quality-of-life questionnaire. CONCLUSIONS: Productivity loss and a prolonged therapy for GO incur great indirect and direct costs.
