Data on the economic burden of lower respiratory tract infections (LRTI) in young children are lacking in Germany. The objective of the cost-of-illness study was to estimate the economic impact of community-acquired LRTI and nosocomial LRTI as well as of infections due to respiratory syncytial virus (RSV), parainfluenza viruses (PIV) and influenza viruses (IV). The economic analysis is part of the PRIDE study, a prospective, multi-centre, population-based epidemiological study on the impact of LRTI in children aged 0 to 36 months in Germany. The analysis includes children with community-acquired infections (1329 cases treated as outpatients, 2039 cases treated as inpatients) and nosocomial infections (90 cases). Medical services consumed were generated by chart abstraction and parental expenses data by telephone interviews within four weeks after physician visit or hospitalisation. Costs were evaluated from following perspectives: third party payer, parent and society. Total costs for outpatient treatment are Euro 123 per LRTI case. Stratified by virus type, total costs per case are Euro 163 (RSV), Euro 100 (PIV) and Euro 223 (IV). Total costs per hospitalised LRTI case amount to Euro 2579. Stratified by virus type, total costs per case are Euro 2772 (RSV), Euro 2374 (PIV) and Euro 2597 (IV). Total costs per nosocomial case are Euro 2814. Economic burden due to LRTI is Euro 213 million annually. It is concluded that treatment of LRTI in children up to age three causes a considerable economic burden in Germany. Presented results are the first data describing the economic burden of LRTI in young children assessed by means of the incidence data for Germany. This cost-of-illness study provides basic data for further decision-making, focusing on the economic assessment of preventive strategies for RSV, PIV and IV infections.

The aim of this study was to assess the incremental cost effectiveness of on-demand versus prophylactic haemophilia therapy in Germany, Sweden, the United Kingdom and The Netherlands from the third-party payers' perspective. Using a decision tree model, the cost effectiveness of on-demand versus prophylactic therapy was analysed by extrapolating data from the European Haemophilia Economic Study to a 1-year analytic time horizon. Five hundred and six patients with severe haemophilia A and B, without inhibitors and at least 14 years of age, were enrolled in this study. Patients treated prophylactically had fewer bleeds than patients treated on-demand. With prophylactic treatment, the incremental cost per avoided bleeding ranged from 6,650 Euro dollars for patients 30 years of age or younger in Germany to 14,140 Euro dollars for patients over 30 years old in Sweden. If quality of life was taken into account, patients receiving prophylactic treatment had higher mean utilities than patients on on-demand therapy. The incremental effectiveness ratios in Germany were 1.2 million Euro dollars per quality-adjusted life year gained for patients 30 years or younger and HIV-positive and 2.2 million Euro dollars for patients 30 years or younger and HIV-negative. In the group aged over 30 years and HIV-positive the on-demand treatment strategy was dominant, whereas in the over 30 years/HIV-negative group the incremental cost-utility ratio was 4.7 million Euro dollars per quality-adjusted life year. Based on our decision analysis, the use of prophylactic treatment was overall more effective than on-demand therapy in young haemophiliacs, but at extremely high cost.

COPD is a major cause of morbidity and mortality in Europe. The purpose of this literature review was to critically evaluate published data on COPD prevalence and the cost of COPD interventions in European countries. Selection of literature was based on article retrieval from a systematic literature search using PubMed and EMBASE. Only articles providing data in European countries published between January 1990 and March 2003 were included. European epidemiological (cross-sectional, cohort, case-control) and economic (cost-of-illness-, cost-minimization-, cost-effectiveness-, cost-benefit-, cost-utility-analysis) studies were included. Of 74 retrieved epidemiologic studies, only seven (9%) fulfilled the inclusion criteria. In the selected literature, COPD prevalence ranged from 3% among Finnish women to 57% among Italian men and women, 45 years and older. Of 56 economic studies, 24 satisfied entry criteria. Results from the final cost-of-illness studies indicated that hospital care and medication represented the major portion of costs associated with COPD. In a survey conducted in 1998/99, annual direct expenditures for COPD treatment per patient in Europe ranged from Euro 530 in France to Euro 3238 in Spain. There was a differential increase in COPD prevalence predominantly related to an aging patient population, with a high incidence of exposure to cigarette smoke. Data also showed differences in the economic impact of COPD in Europe based on the proportion of patients with severe COPD, frequency of exacerbations, and number of hospitalizations. Overall, results of this review demonstrated the need for global epidemiologic and economic studies to allow for more uniform guidelines for the prevention and cost-effective treatment of patients with COPD.
