Electronic Medical Records

Electronic Medical Records and Handheld Computing by Physician Assistants in Clinical Practice An Applied Dissertation Submitted to the Fischler School of Education and Human Services in Partial Fulfillment of the Requirements for the Degree of Doctor of Education Calvin R. Finley, Ed.D., PA-C Assistant Professor Physician Assistant Department College of Allied Health and Nursing Nova Southeastern University

Purpose of the Study This applied dissertation was designed to assess the use of personal digital assistants (PDAs) in association with electronic medical records (EMRs) by physician assistants (PAs) in clinical practice. The use of PDAs is becoming commonplace in the day-to-day activities of many individuals, including health care providers. It is important to have an understanding of the dynamics involved in the diffusion of PDAs and EMRs into the day-to-day clinical practices of PAs and other health care providers.

Hypotheses It can be assumed that the combined use of PDAs and EMRs help PAs to better manage the care of their patients through increased and easier access to key patient information. This improved access would benefit the PA, as well as the patient access to critical patient data helps to improve patient care and diagnosis saves time for the PA Resulting in better informed clinical decisions higher-quality care at lower costs for the patient the medical facility

PAs who utilize a PDA in conjunction with an EMR application in their day-to-day clinical practice are most likely influenced by the practice setting the adoption of an EMR system by the facility in which they practice PAs who utilize a PDA in conjunction with an EMR application perceive a positive influence in the overall care provided to their patients

Purpose of the questionnaire Determine how many PAs were using PDAs in their daily clinical practice How many were using PDAs in conjunction with EMRs What were the factors that influenced the adoption of the use of PDAs in conjunction with EMRs Of those PAs using a PDA in conjunction with EMRs, what was their perception of the way this diffusion of innovation changed their practice of medicine A questionnaire was mailed to the members of the 2002, 2003, and 2004 graduating classes of the PA program of Nova Southeastern University

The questionnaires were mailed to a total of 229 graduates and responses were received from 122 (53%): 38 from the class of 2002 38 from the class of 2003 45 from the class of 2004 1 graduation year left blank

Of the respondents, there were 72 PDA users A total of 5 were using PDAs in conjunction with EMR systems This suggests that there remains a huge gap between early and late adopters of this innovation An analysis of the data indicates that further studies are needed to explore the barriers to the adoption of the use of PDAs in conjunction with EMRs

Background Past studies have shown that family practice residency programs are increasingly making use of handheld computers during residency training (Criswell & Parchman, 2002) There is little evidence that PA programs are providing formal training in the use of PDAs Empirical evidence suggested that increasing numbers of PA students are utilizing PDAs during their training, especially during the clinical portion of their training (Helopoulos, 2003; McCabe & McGehee, 2004; Schaller, 2001)

Rogers (2003) related that scholars of diffusion have found that individuals gain awareness knowledge through behavior that must be initiated, adding that the need for an innovation must usually precede awareness knowledge of the innovation. The results of this study may lead to the development of guidelines that, when put into effect, would increase the effective use of PDAs in association with EMRs to meet the needs of clinicians and patients during the medical encounter.

If the research suggests that PDAs and EMRs are critical to providing greater efficiency and capabilities in the delivery of health care by PAs then it may be beneficial to ensure that PAs are properly prepared during their training to incorporate this technology into their clinical practice. If the trend towards the diffusion of technology into the delivery of health care continues it would be prudent to prepare PAs to be proficient in the use of handheld technology to meet the real-world standards of performance in the health care arena.

Literature Review Explore available data about use of PDAs by healthcare practitioners in association with EMRs Limited studies on use of PDAs in clinical setting Fewer studies on utilization of EMR systems Virtually no studies on use of PDAs in conjunction with EMR systems Evolution of technology in the form of EMR systems in healthcare How EMRs and handhelds can be combined to manage patient information and provide support for clinical decisions and outcomes

Breakdown of Lit Review Diffusion of Innovations [12] Health Professionals and PDAs [4] Health Professionals and EMRs [8] Handheld and EMRs [5]

Innovation Diffusion Theories The familiarity of an innovation and its compatibility with the existing environment and behavior Is strongly linked to its diffusion The more an innovation can integrate and coexist with technologies and social patterns already in place The greater its prospects for adoption and diffusion

Summary of Literature Review Widespread acceptance of use of PDAs by healthcare providers Especially among residents and medical students Main uses of handhelds by clinicians Reviewing electronic medical databases Accessing online drug reference materials Inputting electronic medical information

Summary of Lit Review Adoption of EMRs is not as widespread Problems of non-interoperability High cost of implementation Main impetus behind incorporation of handhelds and EMRs into deliver of healthcare Federal government – under the direction of President George W. Bush

Discussion Study supported findings of previous studies PDAs have gained wide acceptance by healthcare providers (Carroll & Christakis, 2004; Criswell & Parchman, 2002; McLeod et al., 2003; Porn & Patrick, 2002) Acceptance of EMR applications remains slow among physicians Sittig et al., 1999 Despite the high interest in adoption of EMR (Lowes, 2002; Miller et al., 2004) , the diffusion into daily practices of health care providers lags behind adoption of handhelds

A survey by the Healthcare Financial Management Association (HFMA, 2006) found the most significant barriers to EHR adoption: Lack of national information standards and code sets (62%) Lack of available funding (59%) Concern about physician usage (51%) Lack of interoperability (50%)

There is a large disconnect between the number of PAs that use a PDA on a regular basis (59%) and those that use PDA/EMR (6.9%) Use of PDA/EMR lags way behind adoption of either technology, when compared individually PDA use = 59% EMR use = 20% PDA/EMR use = 6.9%

The challenge is to decrease the gap between those who use the PDA alone and those who use the PDA/EMR combination Rao (2002) and Criswell and Parchman (2001) noted that medical residents-in-training were the agents of change for integrating PDAs into clinical practices This is a great opportunity for PAs to become the agents of change to incorporate the PDA/EMR concept into the medical settings in which they provide healthcare

Summary - Conclusion The use of PDAs by PAs and other health care providers is widespread The impetus to go digital with health care records is strong There is an urgency to adopt interoperable EHRs to reduce medical errors and cut health care costs through increased efficiency With the goal of improving medical care to patients

Many questions remain to be researched concerning the level of involvement of PAs in the diffusion of this technology partnership of PDAs and EMRs Future studies should survey a broader group of PAs across the nation to get a better idea of PDA/EMR use among PAs Investigate the role of the PA as change agent in the implementation of the use of PDA/EMR in the delivery of health care in the U.S.

HFMA, 2006 Universal implementation of EHRs will produce a profound societal return---improving care and reducing costs . . . Enhanced quality and patient safety through improved continuity of care and clinical decision making, reduced clerical and administrative costs, and more effective use of health services. (p. 13)

With a large percentage of PAs and other health care providers using PDAs and a greater emphasis on the implementation of EMRs by organizations that provide health care: The integration of PDAs and EMRs should be given a higher priority for the overall success of the diffusion of these innovations into the health care delivery system Future studies should concentrate on isolating the major factors that influence the adoption of PDA use in conjunction with EMRs, so that efforts to support the positive factors and remove barriers can be more focused Unless there is a concerted effort on a national level to negate the barriers to PDA/EMR integration, we may have to give a new meaning to the term “digital divide”
