ABSTRACT: The Quebec health sector has been experiencing a period of great turmoil over the last five years. Among other institutions, hospitals are faced with huge pressures from government funding cuts. Several empirical studies in the information systems field have shown that the use of computer-based information systems could have positive impacts on organizational performance. Many agree to say that health care institutions are no exceptions. But if one wishes to identify the effects of IT on the delivery of care, one must be able to characterize IT for operationalization purposes. The objective of this research project is twofold. Our first aim consists in developing and validating a measurement instrument of IT sophistication in hospitals. Such instrument should provide hospital managers with a diagnostic tool capable of indicating the profile of their respective institutions in regard to IT use and comparing this profile to those of other similar health institutions. In this line of thought, our second objective consists in presenting the IT sophistication profile of Quebec hospitals.

ABSTRACT: One of the recent design goals in Human Computer Interaction has been to extend the sensorymotor capabilities of computer systems to combine the real and the virtual in order to assist the user in his environment. Such systems are called Augmented Reality (AR). Although AR systems are becoming more prevalent we still do not have a clear understanding of this interaction paradigm. In this paper we propose OPAS as a generic framework for classifying existing AR systems. Computer Assisted Medical Interventions (CAMI), for which the added value of AR has been demonstrated by experience, are discussed in light of OPAS. We illustrate OPAS using our system, CASPER (Computer ASsisted PERicardial puncture), a CAMI system which assists in surgical procedures (pericardial punctures). KEYWORDS: Augmented Surgery, CAMI, Augmented Reality, Classification Space 1. INTRODUCTION The term "Augmented Reality" (AR) appears in the literature usually in conjunction with the term "Virtual Reality" (VR). T...
