Objective: The integration of quality indicators into the accreditation process has been recognized as a promising strategy worldwide. This study was to explore the implementation patterns of hospital accreditation through the lens of a systems-theory based model, and determine an international accreditation implementation typology.Design: A qualitative comparative study of five established international hospital accreditation systems was undertaken based on a systems-theoretic holistic healthcare systems relationship model. A set of key attributes relevant to three systems-theoretic model relationships guided data collection, comparison and synthesis.Setting: Hospital accreditation systems in five countries: America, Canada, Australia, Taiwan and France.Results: An accreditation implementation typology was developed based on the data synthesis of the similarities and differences among the relationships. A typology including five implementation types of hospital accreditation systems (TYPE I-V) was induced. TYPE I is a basic stand-alone accreditation system. The higher types represent stronger relationships among accreditation system, healthcare organizations and quality measurement systems. The five settings have shifted their accreditation approaches from the basic type (TYPE I).Conclusions: The implementation typology of hospital accreditation could serve as a roadmap for refining hospital accreditation systems toward an integrative approach for continuous quality improvement.

Background: The Seven Countries Study in the 1960s showed very low mortality from coronary heart disease (CHD) in Japan, which was attributed to very low levels of total cholesterol. Studies of migrant Japanese to the USA in the 1970s documented increase in CHD rates, thus CHD mortality in Japan was expected to increase as their lifestyle became Westernized, yet CHD mortality has continued to decline since 1970. This study describes trends in CHD mortality and its risk factors since 1980 in Japan, contrasting those in other selected developed countries.Methods: We selected Australia, Canada, France, Japan, Spain, Sweden, the UK and the USA. CHD mortality between 1980 and 2007 was obtained from WHO Statistical Information System. National data on traditional risk factors during the same period were obtained from literature and national surveys.Results: Age-adjusted CHD mortality continuously declined between 1980 and 2007 in all these countries. The decline was accompanied by a constant fall in total cholesterol except Japan where total cholesterol continuously rose. In the birth cohort of individuals currently aged 50-69 years, levels of total cholesterol have been higher in Japan than in the USA, yet CHD mortality in Japan remained the lowest: >67% lower in men and > 75% lower in women compared with the USA. The direction and magnitude of changes in other risk factors were generally similar between Japan and the other countries.Conclusions: Decline in CHD mortality despite a continuous rise in total cholesterol is unique. The observation may suggest some protective factors unique to Japanese. [ABSTRACT FROM AUTHOR]
