    This paper examines effects of reference pricing for prescription drugs in German social health insurance based on econometric panel data methods. We analyze the effect on ex-factory prices. Moreover, we investigate whether manufacturers adapt prices of their products not subject to reference pricing as a consequence of changes in reference prices of their products subject to reference pricing.We use a large panel data set of nearly all German prescription drugs on a monthly basis between October 1994 and July 2005. Altogether, the data comprise almost 4 million observations. They provide information on ex-factory prices, reference prices, manufacturers, type of prescription drug, and market entries and exits. Our results show that there is no full price adjustment:A 1%-change in reference prices leads to a 0.3%-change in market prices. Price adjustment, however, is fast, it mostly happens in the first month. Furthermore, the first introduction of a reference price reduces market prices of the affected products by approximately 14%. Finally, we observe a significant time effect which is positive in the market without reference prices and negative in that with reference price.Price elasticity, temporal development, fixed effects model

    Background Necrotising pancreatitis, and particularly infected necrosis, are still associated with high morbidity and mortality. Since 2011, a step-up approach with lower morbidity rates compared to initial open necrosectomy has been established. However, mortality and complication rates of this complex treatment are hardly studied thereafter. Methods The German Pancreatitis Study Group performed a multicenter, retrospective study including 220 patients with necrotising pancreatitis requiring intervention, treated at 10 hospitals in Germany between January 2008 and June 2014. Data were analysed for the primary endpoints "severe complications" and "mortality" as well as secondary endpoints including "length of hospital stay", "follow up", and predisposing or prognostic factors. Results Of all patients 13.6% were treated primarily with surgery and 86.4% underwent a step-up approach. More men (71.8%) required intervention for necrotising pancreatitis. The most frequent etiology was biliary (41.4%) followed by alcohol (29.1%). Compared to open necrosectomy, the step-up approach was associated with a lower number of severe complications (primary composite endpoint including sepsis, persistent multiorgan dysfunction syndrome (MODS) and erosion bleeding: 44.7% vs. 73.3%), lower mortality (10.5% vs. 33.3%) and lower rates of diabetes mellitus type 3c (4.7% vs. 33.3%). Low hematocrit and low blood urea nitrogen at admission as well as a history of acute pancreatitis were prognostic for less complications in necrotising pancreatitis. A combination of drainage with endoscopic necrosectomy resulted in the lowest rate of severe complications. Conclusion A step-up approach starting with minimal invasive drainage techniques and endoscopic necrosectomy results in a significant reduction of morbidity and mortality in necrotising pancreatitis compared to a primarily surgical intervention

    Price Elasticities and Social Health Insurance Choice in Germany: A Dynamic Panel Data Approach

    Full text link
    In 1996 free choice of health insurers has been introduced in the German social health insurance scheme. Competition between insurers was supposed to increase efficiency. A crucial precondition for effective competition among health insurers is that consumers search for lower-priced health insurers.We test this hypothesis by estimating the price elasticities of insurers? market shares. We use unique panel data and specify a dynamic panel model to explain changes in market shares. Estimation results suggest that short-run price elasticities are smaller than previously found by other studies. In the long-run, however, estimation results suggest substantial price effects

    Claudin 4 Is Differentially Expressed between Ovarian Cancer Subtypes and Plays a Role in Spheroid Formation

    Claudin 4 is a cellular adhesion molecule that is frequently overexpressed in ovarian cancer and other epithelial cancers. In this study, we sought to determine whether the expression of claudin 4 is associated with outcome in ovarian cancer patients and may be involved in tumor progression. We examined claudin 4 expression in ovarian cancer tissues and cell lines, as well as by immunohistochemical staining of tissue microarrays (TMAs; n = 500), spheroids present in patients’ ascites, and spheroids formed in vitro. Claudin 4 was expressed in nearly 70% of the ovarian cancer tissues examined and was differentially expressed across ovarian cancer subtypes, with the lowest expression in clear cell subtype. No association was found between claudin 4 expression and disease-specific survival in any subtype. Claudin 4 expression was also observed in multicellular spheroids obtained from patients’ ascites. Using an in vitro spheroid formation assay, we found that NIH:OVCAR5 cells treated with shRNA against claudin 4 required a longer time to form compact spheroids compared to control NIH:OVCAR5 cells that expressed high levels of claudin 4. The inability of the NIH:OVCAR5 cells treated with claudin 4 shRNA to form compact spheroids was verified by FITC-dextran exclusion. These results demonstrate a role for claudin 4 and tight junctions in spheroid formation and integrity

    Quality Indicators for the Management of Barrett’s Esophagus, Dysplasia, and Esophageal Adenocarcinoma: International Consensus Recommendations from the American Gastroenterological Association Symposium

    Get PDF
    The development of and adherence to quality indicators in gastroenterology, as in all of medicine, is increasing in importance to ensure that patients receive consistent high-quality care. In addition, government-based and private insurers will be expecting documentation of the parameters by which we measure quality, which will likely affect reimbursements. Barrett’s esophagus remains a particularly important disease entity for which we should maintain up-to-date guidelines, given its commonality, potentially lethal outcomes, and controversies regarding screening and surveillance. To achieve this goal, a relatively large group of international experts was assembled and, using the modified Delphi method, evaluated the validity of multiple candidate quality indicators for the diagnosis and management of Barrett’s esophagus. Several candidate quality indicators achieved >80% agreement. These statements are intended to serve as a consensus on candidate quality indicators for those who treat patients with Barrett’s esophagus

    Reform of Prescription Drug Reimbursement and Pricing in the German Social Health Insurance Market: A Comparison of Three Scenarios

    No full text
    We review regulation of two important parameters for third-party payers and manufacturers of prescription drugs: regulation of reimbursement and pricing. We find that centralised regulation of reimbursement and pricing prevails in the 15 original EU member countries (EU-15) and in European Free Trade Association (EFTA) countries. Compared with countries such as Switzerland, The Netherlands, France and England, regulation in the German social health insurance system is rather unique. First, market approval is nearly always equivalent to reimbursement. Second, manufacturers are free to determine prices but internal reference prices restrict them from actually doing so for generics and therapeutic substitutes. In order to contain rising expenditures for prescription drugs in Germany, and to set incentives for physicians to consider the costs as well as the benefits of prescriptions, three reform scenarios are feasible. The first scenario maintains centralised reimbursement and centralised pricing; the second maintains centralised reimbursement but switches to decentralised pricing (similar to social health insurance in Israel and Medicare in the US). Third-party payers would be able to negotiate with manufacturers about discounts and market shares for genetic and therapeutic substitutes. In the third scenario, pricing and reimbursement would be decentralised (similar to private health insurance in the US). We suggest that the second scenario is a viable compromise between consumer protection and a more competitive and cost-effective market for prescription drugs in German social health insurance and other similar markets for prescription drugs.Health-insurance, Pricing, Regulatory-process, Reimbursement

    Alternative mating tactics in the yellow dung fly: resolving mechanisms of small-male advantage off pasture

    Full text link
    Recent work suggests that the yellow dung fly mating system may include alternative patroller-competitor mating tactics in which large males compete for gravid females on dung, whereas small, non-competitive males search for females at foraging sites. Small males obtain most matings off pasture, yet the behavioural mechanism(s) giving rise to this pattern are unknown. We investigated the male and female behaviours that determine mating success in this environment by conducting field mating experiments and found small males to benefit from several attributes specific to the off-pasture mating environment. First, small males from foraging sites exhibited higher mating propensity, indicating that large males away from dung may be depleted of energy and/or sperm. Second, small males were more discriminating, being significantly less likely to attempt with non-gravid females, which are absent on dung but common off pasture. Third, non-gravid females were generally more likely to actively struggle and reject mating attempts; however, such behaviours occurred disproportionately more often with large males. Female Scathophaga stercoraria thus appear to preferentially mate with small males when off pasture. These findings challenge assumptions about male-female interactions in systems with alternative mating tactics and reveal hidden processes that may influence selection patterns in the field

    These data were obtained using experimental matings conducted in Plexiglas chambers in the field. Male mating attempts were recorded (Attempt/No attempt), latency to attempt (min), outcome of attempt (Copulation/Rejection), capture success (Yes/No), female resistance (Yes/No), female resistance duration (sec), and male displacement when faced with resistance (Yes/No). Raw measures of body size are also included in reticle units (at 32x mag). Finally, female egg development was recorded as either nongravid or gravid (meaning female clutch visually appeared mature)
