Capital intensive hospital technology and illness: an analysis of American state data

This paper: describes the development of a 'hospital technology index' to measure the level of capital intensive medical technology in each of the 50 U.S. states and the District of Columbia, reports differences between states in scores on this index, and tests the hypothesis that there is a low but significant negative correlation between the level of capital intensive medical technology and the level of illness. The three subscales of the hospital technology index have high alpha coefficients of reliability, are reasonably orthogonal, and there is at least some evidence of construct and discriminant validity for each. The multiple regression analysis suggests that there is either no relation between capital intensive medical technology and the rate of illness or that there is a slight tendency for the illness rate to increase as the level of technology increases. Eight possible explanations for the findings are discussed.
