Influenza Vaccination Coverage Rates in 5 European Countries: a Population-Based Cross-Sectional Analysis of the Seasons 02/03, 03/04 and 04/05

Introduction:: Influenza continues to be a considerable health problem in Europe. Vaccination is the only preventive measure, reducing mortality and morbidity of influenza in all age groups Objectives:: The objective of this survey was to assess and compare the level of influenza vaccination coverage during three consecutive influenza seasons (02/03, 03/04, 04/05) in the five European countries United Kingdom, France, Italy, Germany and Spain, understand the driving forces and barriers to vaccination now and 3 years ago and determine vaccination intentions for the following winter. Methods:: We conducted a random-sampling, telephone-based household survey among non-institutionalized individuals representative of the population aged 14 and over. The surveys used the same questionnaire for all three seasons. The data were subsequently pooled. Four target groups were determined for analysis: (1) persons aged 65 and over; (2) people working in the medical field; (3) persons suffering from chronic illness and (4) a group composed of persons aged 65 and over or working in the medical field or suffering from a chronic illness. Results:: The overall sample consisted of 28,021 people. The influenza vaccination coverage rate increased from 21.0% in season 02/03 to 23.6% in season 03/04 and then to 23.7% in season 04/05. The differences between the seasons are statistically significant (p = 0.01). The highest rate over all countries and seasons had Germany in season 04/05 with 26.5%, Spain had in season 02/03 with 19.3% the lowest rate totally. The coverage rate in the target group composed of person's aged 65 and over or working in the medical field or suffering from a chronic illness was 49.7% in season 02-04 and 50.0% in season 04/05. The driving forces and barriers to vaccination did not change over the years. The most frequent reasons for being vaccinated given by vaccines were: influenza, considered to be a serious illness which people wanted to avoid, having received advise from the family doctor or nurse to be vaccinated and not wanting to infect family and friends. Reasons for not being vaccinated mentioned by people who have never been vaccinated were: not expecting to catch influenza, not having considered vaccination before and not having received a recommendation from the family doctor to be vaccinated. Options encouraging influenza vaccination are: recommendation by the family doctor or nurse, more available information on the vaccine regarding efficacy and tolerance and more information available about the disease. The adjusted odds ratio of receiving influenza vaccine varied between 2.5 in Germany and 6.3 in the United Kingdom in any risk group. Conclusion:: The vaccination coverage rate increased from the first season (21.0%) to the third season (23.7%) by 2.6%. The family doctor is the most important source of encouragement for people to be vaccinated against influenza. It seems that the public would be more likely to be vaccinated if they had more information on the efficacy and tolerance of the vaccine, as well as the disease. We therefore suggest that family doctors be better informed on influenza vaccine and the disease itself, so that they can actively inform their patients on these topic

Prospective Survey of AntibioticUtilization in Pediatric Hospitalized Patients to IdentifyTargets for Improvement of Prescription

Abstract. : Background: : The rise in the use of antibiotics has resulted in increasing health care costs and the emergence of resistant bacteria. Little is known about the general misuse of antibiotics in hospitalized children. We evaluated the utilization of antibiotics in a pediatric teaching hospital aiming to identify targets for improvement of prescription. Patients and Methods: : Clinical, radiological, laboratory and treatment data of patients hospitalized in a pediatric medical and a pediatric surgery ward were prospectively collected during a 6-week period. A subsequent review of the collected data by a pediatric infectious diseases specialist, taking into consideration existing in-house treatment guidelines, was carried out. Results: : A total of 125 (36%) of 349 patients was prescribed 246 antibiotics. The median length of hospital stay for children prescribed antibiotics was 5 days (range, 2-30 days) and for those not prescribed 3 days (1-32 days; p < 0.001). Of 154 patients in the medical ward, 64 (42%) received antibiotics, compared to 61 (31%) of 195 patients in the surgical ward (p < 0.05). Empirical prescriptions were more frequent than prophylactic ones, which were more frequent than therapeutic prescriptions (136 [55%] vs 94 [38%] vs 16 [7%]; p < 0.001). Overall, 85% of the prescriptions were considered justified. The rates of inappropriate prescriptions were similar in the medical and surgical ward, and higher for therapeutic (19%) or prophylactic treatment (18%) than for empirical treatment (12%). Higher inappropriate prescription rates were noted for macrolides than for co-trimoxazole and β-lactams (50% vs 18% and 15%, respectively; p < 0.05). Conclusion: : Efforts need to be undertaken towards continuous education of medical staff on judicious antibiotic use, as well as ensuring compliance with existing guidelines. Improvement in the availability of rapid diagnostic methods to discern viral from bacterial infections may help reduce the numbers of empiric therapies in favor of pathogen-targeted therapeutic treatment

Kosten-Nutzen-Effektivität von Clopidogrel bei akutem Koronarsyndrom: Langzeitbehandlung, sekundäre Prophylaxe, Koronarintervention

Clopidogrel, a thienopyridine antiplatelet agent, is an adenosine diphosphate (ADP) receptor antagonist. Clopidogrel inhibits ADP binding to its platelet receptor and subsequent ADP-mediated activation of the glycoprotein IIb/IIIa complex, thus inhibiting platelet aggregation. Clopidogrel irreversibly modifies the ADP receptor so platelets are affected for the remainder of their life span. The treatment of acute coronary syndromes consists of an inpatient diagnosis and inpatient treatment usually done in an emergency room and intensive care unit and a long-term secondary prophylaxis of the underlying condition, coronary artery disease. Therefore, efficacy of different treatments and their implication on costs have to be examined over a long time period. The cost perspective (hospital, society, country) is another important point. In each country different charges for drugs, medical procedures and hospitalization are existing; varying drug costs may result in a more or less cost-effective ratio of a treatment. Furthermore, not only direct medical costs, but also implications on indirect costs should be taken into account when measuring cost-effectiveness of treatments. Worldwide, cardiovascular diseases account for a significant burden of hospital and societal costs. In particular for colleagues running their own private practice, cost-consciousness has become important in recent times. On the other hand, there has to be carried the duty to accord patients the best possible treatment. This – against the background of ethical responsibility, physicians can come into a conflict – continues to require cost-effectiveness studies in the future. By means of the set-forth results configurations can be seen in which clopidogrel has both, a benefit on the medical and on the economic side of view. From most of the quoted analyses application of clopidogrel was warrantable and the scope of costs within the amount of established cardiovascular therapies

Cost-effectiveness of trastuzumab in the adjuvant treatment of early breast cancer: a model-based analysis of the HERA and FinHer trial

BACKGROUND: Routine adjuvant administration of trastuzumab (T) has been implemented in most centers, but its economic impact has not yet been well examined. METHODS: A Markov model was constructed based on clinical data of the Herceptin Adjuvant (HERA) and the Finland Herceptin (FinHer) trials. Costs from the perspective of a Swiss health care provider were calculated based on resource use. RESULTS: On the basis of HERA data, our model yielded an overall survival rate of 71.8% for the T group versus 62.8% for the control group [risk ratio (RR) = 0.87) after 10 years and 62.9% versus 52.7% (RR = 0.84) after 15 years. Cost-effectiveness resulted in 40505 Euros (EUR) per life years gained (LYG) after 10 years and 19673 EUR per LYG after 15 years. For the FinHer regimen, overall survival after 10 and 15 years resulted in 81.8% versus 66.1% (RR = 0.81) and 73.6% versus 57.0% (RR = 0.77). Costs of 8497 EUR per patient could be saved after 10 years and 9256 EUR after 15 years compared with the control group. CONCLUSION: In a long-term perspective, adjuvant T based on the HERA regimen can be considered cost-effective. The regimen used in the FinHer trial is even cost saving, but estimations are based on a single small tria

Trastuzumab beyond progression: a cost-utility analysis

Background: The continuation of trastuzumab beyond progression in combination with capecitabine as secondary chemotherapy for HER2-positive metastatic breast cancer (MBC) prolongs progression-free survival without a substantial increase in toxicity. Patients and methods: A Markov cohort simulation was used to follow the clinical course of typical patients with MBC. Information on response rates and major adverse effects was derived, and transition probabilities were estimated, based on the results of the Breast International Group 03-05 clinical trial. Direct costs were assessed from the perspective of the Swiss health care system. Results: The addition of trastuzumab to capecitabine is estimated to cost on average an additional of €33 980 and to yield a gain of 0.35 quality-adjusted life years (QALYs), resulting in an incremental cost-effectiveness ratio of €98 329/QALYs gained. Probabilistic sensitivity analysis showed that the willingness-to-pay threshold of €60 000/QALY was reached in 12% of cases. Conclusion: The addition of trastuzumab to capecitabine in MBC patients is more expensive than what is typically regarded as cost-effective but falls within the value ranges found for established regimens in the treatment of MB

Risk factors for chemotherapy-induced neutropenia occurrence in breast cancer patients: data from the INC-EU Prospective Observational European Neutropenia Study

BACKGROUND: Chemotherapy-induced neutropenia (CIN) places patients at risk of life-threatening infections. While reduction of chemotherapy dose or delay of the subsequent treatment cycle and, consequently, reduction of relative dose intensity (RDI) may limit myelotoxicity, these actions can also impact adversely on treatment outcome and should be avoided in adjuvant settings. PATIENTS AND METHODS: Based on data from 444 breast cancer patients in the INC-EU Prospective Observational European Neutropenia Study, we have evaluated patient-specific and treatment-specific factors that impact on the incidence of grade 4 CIN (absolute neutrophil count <0.5 x 10(9)/L), either during the first or in any cycle of (neo)adjuvant chemotherapy, across a range of regimens and doses. RESULTS: Using multivariate logistic regression analysis, risk factors for grade 4 CIN were identified as older age, lower weight, higher planned dose intensity of doxorubicin, epirubicin, or docetaxel, higher number of planned cycles, vascular comorbidity, lower baseline white blood cell count, and higher baseline bilirubin. Use of colony-stimulating factor before a neutropenic event occurred, dose delays, and dose reductions were protective against grade 4 CIN. CONCLUSIONS: By identifying risk factors for grade 4 CIN, CSF prophylaxis may be appropriately targeted to prevent low RDI in patients treated with curative intent

Cost-effectiveness of oral alitretinoin in patients with severe chronic hand eczema - a long-term analysis from a Swiss perspective

BACKGROUND: The impact on patients suffering from chronic hand eczema (CHE) is enormous, as no licensed systemic treatment option with proven efficacy for CHE is available. Alitretinoin is a novel agent which showed high clinical efficacy in patients with severe, refractory CHE. We assessed the cost-effectiveness of alitretinoin for CHE patient treatment from a Swiss third party payer perspective. A further objective of this study was to determine the burden of disease in Switzerland. METHODS: A long-term Markov cohort simulation model was used to estimate direct medical costs (euro) and clinical effectiveness (quality adjusted life years, QALYs) of treating severe CHE patients with alitretinoin. Comparison was against the standard treatment of supportive care (optimised emollient therapy). Information on response rates were derived from a randomized controlled clinical trial. Costs were considered from the perspective of the Swiss health system. Swiss epidemiological data was derived from official Swiss Statistic institutions. RESULTS: Annual costs of alitretinoin treatment accounted for 2'212 euro. After a time horizon of 22.4 years, average remaining long-term costs accounted for 42'208 euro or 38'795 euro in the alitretinoin and the standard treatment arm, respectively. Compared with the standard therapy, the addition of alitretinoin yielded an average gain of 0.230 QALYs at the end of the simulation. Accordingly, the incremental cost-effectiveness ratio resulted in 14'816 euro/QALY gained. These results were robust to changes in key model assumptions. CONCLUSION: The therapy for CHE patients is currently insufficient. In our long-term model we identified the treatment with alitretinoin as a cost-effective alternative for the therapy of CHE patients in Switzerland

Improved S factor of the 12C(p,γ)13N reaction at E=320–620 keV and the 422 keV resonance

The 12C(p,γ)13N reaction is the onset process of both the CNO and hot CNO cycles that drive massive star, red and asymptotic giant branch star, and novae nucleosynthesis. The 12C(p,γ)13N rate affects the final abundances of the stable 12,13C nuclides with ramifications for meteoritic carbon isotopic abundances and the s-process neutron source strength. Here, an underground measurement of the 12C(p,γ)13N cross section is reported. The present data, obtained at the Felsenkeller shallow-underground laboratory in Dresden (Germany), encompass the 320–620 keV center of mass energy range to include the wide and poorly constrained E=422 keV resonance that dominates the rate at high temperatures. This work's S-factor results, lower than literature by 25%, are included in a comprehensive R-matrix fit, and the energy of the 12+ first excited state of 13N is found to be 2369.6(4) keV with a radiative and proton width of 0.49(3) eV and 34.9(2) keV, respectively. A reaction rate, based on the present R-matrix fit and extrapolation, is suggested
