The productivity impact of information technology in the healthcare industry: an empirical study using a regression spline-based approach

This paper explores the productivity impact of information technology (IT) in the healthcare industry using a regression spline (RS)-based approach. Application of the RS-based approach offered additional valuable insights that contribute to our understanding of the complex relationship between investments in IT and organizational productivity. For example, the results of this study suggest that investments in the IT Stock has a positive impact on productivity only under certain conditions, and that this impact of IT is not uniform but is conditioned both by the amount invested in the IT Stock and the investments in Non-IT Capital. q 2003 Elsevier B.V.
