Information technology is increasingly crucial to health care organization and delivery of health care. Policy makers and payers have frequently advocated health information technology (HIT) adoption to improve both the quality and efficiency of health care delivery. Despite its importance, little empirical research has been conducted on the economics of health information technology. This session explores HIT adoption as well as its resultant effect on quality in both inpatient and outpatient settings in the US environment. The role of complementary technological and organizational inputs is also studies. In particular, Simon and White study the relationship between HIT adoption and quality in US outpatient physician practices. McCullough and colleagues measure the effect of HIT on quality in US hospitals – they incorporate the role of complementary technological and organizational inputs in the production of patient safety. Finally, Li explore the potential for HIT to improve both the quality and efficiency of Chinese health care delivery. Li draws from the US HIT experience to study how HIT might be incorporated into ongoing restructuring of the Chinese health care delivery system.
