Background & objectives: At the present time, health care services have been increasingly transformed to a competitive issue and many factors influence usage of hospital services and selection of a hospital by the patients. This study has been performed for surveying effective factors on selecting a public or private hospital among non-emergent patients of Ardabil hospitals in 2012.

  Method: This research was a cross-sectional descriptive-correlational study and the statistical population was non emergent patients of four public and two private hospitals of Ardabil in 2012. The samples (598 patients) were collected by stratified random sampling method. Data-gathering tool was a researcher-made questionnaire and data were analyzed by descriptive statistics, frequency [distribution] tables, and logistic regression analysis.

  Results: The results depicted a direct interdependence between selecting a hospital (public or private) and the three factors of social elements, hospital services, and hospital facilities with a confidence coefficient of 92%. Based on logistic regression analysis and Exp(B) coefficient, the patients’ priorities for hospital choosing were hospital services, social elements, and hospital facilities with Exp(B) of 1.932, 1.332, and 0.338, respectively.

  Conclusion: The most important factor for choosing public hospitals was lower cost of services and for private hospitals was physician’s recommendation. The strong effects of these two factors have overshadowed other variables.
