Effects of Health Information Technology Implementation on Clinical Outcomes and Quality of Care

A study of the effects of Health Information Technology (HIT) on health care outcomes and quality of care was conducted to explore evidence for the relationship between different types and levels of Health Information Technology and Health Information Exchange (HIE) implementation and key healthcare outcomes. Specifically, six continuous variables representing HIT-HIE were constructed using the validated American Hospital Association's (AHA) HIT instrument. Three categorical variables were also used. A study was also conducted on the effects of HIT-HIE on Emergency Department outcomes. The first sample was drawn from CMS MedPar data from 2006--2012, for all inpatients with specific diagnoses outlined in this paper. The second study was conducted using the National Hospital Ambulatory Medical Care Survey (NHAMCS).
