Project title: Relationship between Clinical Information Technology Scores, Information Technology Investments and Clinical and Financial Outcomes at Parkland

Human subjects IRB approved project number (where applicable):

The TEXCITE research is supported by the Johns Hopkins IRB NA-00001262, where the study is being principally conducted.

The first phase of this Parkland study, in which Aaron is involved, would involve no patients or personal health information and does not require IRB approval.

Animal subjects IRB approved project number (where applicable): NA

Project Type: health services research

Brief Description of Project:
Clinical information technologies (CIT) such as electronic medical records (EMR), computerized provider order entry (CPOE), and digital radiology systems promise reductions in waste, gains in efficiency, and improvements in the quality of care. It has been suggested that these technologies may be able to reduce disparities in care for minority and underserved populations, such as those who receive care at Parkland Health & Hospital System (PHHS). However, there are few studies which have conclusively demonstrated this association. Furthermore, there is not an established conceptual model to frame these health services research questions.
We previously developed a CIT assessment tool (CITAT) that examines the performance of a hospital's information system from a clinical viewpoint. The instrument has reliability and validity and has been tested in multiple studies. In March 2006, the CITAT was deployed at Parkland Health & Hospital System (PHHS) as part of the Texas Clinical Information Technology Evaluation (TEXCITE) project.3 As PHHS deploys advanced information systems over the next 5 years we will he examining the relationship between the change in CITAT scores and specific process and outcome measures. As part of the first phase of this project, Andrew will spend the summer performing 1) a systematic review of the clinical measures that are sensitive to changes in the IT environment and which have, independently, been associated with health care disparities; 2) a conceptual model that frames the relationship between information technologies and health care disparities; and 3) develop strategies to examine the relationship between CITAT scores and healthcare disparities at PHHS. We would expect to submit the conceptual model and results of the systematic review for publication in a peer-review health services research journal.
