Abstract

INTRODUCTION: As a health care organization, achieving security and high reliability is a goal in hospitals. Therefore, this research is concerned with the development of a structural high-reliability model in public hospitals of Iran.

METHODOLOGY: This applied research was conducted in 2015 with a population that included directors, managers, faculty members and hospital affairs experts. A totalof 200 questionnaires were distributed in five areas of the country based on a cluster sampling method. The structural validity of the questionnaire was approved through confirmatory factor analysis test and its reliability was calculated as 0.73 by Cronbach’s alpha test. Moreover, data were analyzed by SPSS 18 and LISREL 8.5 software using factor analysis and mathematical models; and the confirmation of the model was assessed based on confirmatory factor analysis.

FINDINGS: The results of factor analysis indicated that exploitable factors for factor analysis included selection of axis of reluctance to simplify interpretation, preoccupation with failure, sensitivity to operations, resilience and deference to expertise. Conversely, the ratio between Chi-Do index and degree offreedom was less than three, the RMSEA index was lower than 0.08, The NFI, NNFI, IFI and CFI values were higher than 0.9.

CONCLUSIONS: By considering the axes of lack of tendency towards simplification of interpretations, concerns and tolerance against failure, sensitivity towards operations, flexibility and specialization hospitals will be able to achieve high-reliability criteria.
