Dr. Vreeman's research interests are centered on understanding and promoting effective organization, analysis, management, and use of information in healthcare. The principle focus areas are:

• The use of standardized clinical vocabularies to support electronic health information exchange
• Investigation of medical informatics applications to improve healthcare delivery and research
  

Current projects include:

Creation, Maintenance and Distribution of Logical Observation Identifiers Names and Codes (LOINC®)

Investigators

• Paul Dexter, MD (Indiana University School of Medicine and Regenstrief Institute, Inc)
• Daniel J. Vreeman, PT, DPT, MS (Indiana University and Regenstrief Institute, Inc)

Summary

The Regenstrief Institute has been a leader and active participant in medical informatics standards development. IU/Regenstrief Institute initiated the LOINC® vocabulary standard for laboratory and clinical observations. LOINC has been adopted by the largest commercial laboratories and most Federal agencies (CDC, DOD, CMS). This project is focused on the creation, maintenance, and distribution of the LOINC vocabulary.

Automated Mapping of Local Clinical and Laboratory Terms to LOINC

Investigators

• Daniel J. Vreeman, PT, DPT, MS (Indiana University and Regenstrief Institute, Inc)
• Clement J. McDonald, MD (Indiana University School of Medicine and Regenstrief Institute, Inc)

Summary

The goal of anywhere, anytime medical information exchange is impeded by the plethora of local conventions for identifying health data in separate electronic systems. Mapping local terms to a standardized vocabulary such as LOINC bridges the many islands of health data that exists and facilitates data aggregation. But, mapping terms is a complex, labor-intensive process. Automating the process of mapping local terms to LOINC has the potential to improve the efficiency and consistency of the mapping process.

Use of Controlled Vocabularies to Support Electronic Health Information Exchange

Investigators

• Daniel J. Vreeman, PT, DPT, MS (Indiana University and Regenstrief Institute, Inc)

Summary

Interoperable health information exchange is hindered by the myriad idiosyncratic conventions for identifying similar data in separate electronic systems. Clinicians, administrators, and researchers all need a complete set of clinical information, coalesced from all of the various sources that produce health data. Mapping local observation codes to a universal, controlled terminology provides a bridge across those islands of data, yet this work is challenging and resource intensive. The goal of this work is describe and understand the challenges and develop tools to overcome them.

Summary

With burgeoning pressures to better manage clinical information through information technology, this project sought to investigate the role of Electronic Health Records (EHRs) in physical therapist practice. This project identified, reviewed, and summarized the benefits, barriers, and key factors for success in implementing EHRs in physical therapist practice.

Creating an Indiana-Ohio Center for Traumatic Amputation Rehabilitation Research

Investigators

• Mark S. Sothmann, PhD (Indiana University, Indiana Center for Rehabilitation Sciences and Engineering Research)
• Daniel J. Vreeman, PT, DPT, MS (Indiana University and Regenstrief Institute, Inc)
• Bradley Doebbeling, MD (Indiana University School of Medicine, Regenstrief Institute, Inc, and Richard L. Roudebush Veterans Administration Medical Center)

• Stephen Wilson, PhD (The Ohio State University)
• Deborah S. Larsen, PhD (The Ohio State University)

Summary

Rehabilitation represents the interface of technology and therapeutic interventions to promote increased function and quality of life. The Iraq and Afghan conflicts have highlighted the dearth of information on the long term outcomes of military personnel experiencing traumatic amputation from conflict. This project proposes to establish an Indiana-Ohio Center for Traumatic Amputation Rehabilitation Research (Indiana-Ohio Center) to promote outcomes research on a population with potentially unique rehabilitation needs for long-term health and welfare. Phase I will create the Indiana-Ohio Center and will establish a nation-wide database of Vietnam veterans with traumatic amputation as phase 1 of a multiple year, three phase approach to fully testing the overarching hypothesis. Phases 2 and 3 will focus on collecting data pertaining to key outcomes indicators.

Research Environment

This project seeks to establish the Indiana-Ohio Center which will be administered by the Indiana Center for Rehabilitation Sciences and Engineering Research (ICRSER). ICRSER is housed in the Indiana University School of Health and Rehabilitation Sciences which is one of seven collaborating schools on the Indiana University Purdue University (IUPUI) campus, the Richard L. Roudebush Veterans Affairs Medical Center (VAMC), and the Rehabilitation Hospital of Indiana. The Indiana-Ohio Center will establish research priorities and will serve as an organizational structure through which subsequent research proposals will be submitted for competitive funding of outcomes studies conducted to give direction to the unique rehabilitation needs of those experiencing traumatic amputation arising from conflict.

The goal of this project was to develop and test a chart abstraction tool for describing the quality of pediatric ADHD care using computer-interpretable paper forms. Our simple, reliable chart abstraction tool for evaluating compliance with ADHD guidelines will be useful in future quality improvement efforts. In pilot data, few charts documented compliance.
