Availability and quality of data on pharmaceutical benefit financing components of health care system in United States, United Kingdom, Denmark, Germany, Italy and Poland.

The abstract presents results of the "InterQuality Project - International Research Project on Financing Quality in Healthcare" funded by the 7th Framework Programme (FP7) for Research and Technological Development of the European Union. Grant Agreement No: HEALTH-F3-2010-261369 Objective: To assess reliability, validity and completeness of data on pharmaceutical benefit financing components of health care in United States, United Kingdom, Denmark, Germany, Italy and Poland Theory: Information and guidance used by authorities for decision making in the financing of pharmaceutical care should be reliable, valid and complete. Methods: A systematic review of literature published in the last 10 years, found electronically in Medline, Embase, the Cochrane Library and SCOPUS, supplemented by a manual search, was conducted. Quality of publications was critically appraised using PRISMA [1], MOOSE [2] and STROBE [3] checklists. Contents of found literature were assessed in terms of consistency, coherence and strength. Results: In total, 439 full text publications were included, of which 198 papers were assessed for quality. Of these, 24,6%, 31,2% and 22,1% publications presented high levels of: consistency, coherence and strength, respectively, and 4,3% presented concurrently high levels of all assessed areas. Several areas of weak data availability were identified. Discussion: No comparable analyses were found. Credible data were often unavailable. A questionnaire and a template helpful to collect data where more information is needed were developed, validated and will be sent to experts from InterQuality Consortium countries. Conclusion: To improve the quality of information available to decision makers, so that it is more credible, multiple sources should be used. [ABSTRACT FROM AUTHOR]
