Abstract

Personal electronic health records are seen as a key component to improved health care for patients, empowering motivated patients by giving them access to their own records resulting in increased self-care, shared decision making, and better clinical outcomes. Benefits through electronic record keeping would also accrue to health care providers through the availability and retrievability of data, reduced duplication of medical tests, more effective physician diagnosis and treatment, reduced incidence of prescription errors, and flagging inappropriate drug combinations. Utilizing information technology could also moderate the cost of health care services. Electronic health records would also improve clinical research through access to a large database of patient electronic records for research and determining best practices. Although potential benefits are considerable, many challenges to implementation must be addressed and resolved before this potential of improved health care provision and cost efficiency can be realized.

Introduction

Personal Health Records (PHRs) and Electronic Health Records (EHRs) are seen as key components to improving health care to patients as well as promoting wellness to the public at large (Tang, Ash, Bates, Overhage, & Sands, 2006). Electronic health records are digital depositories for clinician records and managed by clinicians or health institutions. Hayrinen et al. describe EHRs as repositories of patient data in digital form, stored and exchanged securely, and accessible by multiple authorized users that contain retrospective, concurrent, and prospective information. Their primary purpose is to support continuing, efficient, and quality orientated health care (Hayrinen, Saranto, & Nykanen, 2008). An advisory panel to the U.S. government’s Health Information Technology Adoption Initiative has listed the functions of EHRs as 1) having the ability to electronically collect and store data about patients, 2) having the ability to supply that information to health providers on demand, 3) having the ability to allow physicians to enter patient care orders on the computer, and 4) having the ability to provide health professionals with health care decision making support (Blumenthal & Glasor, 2007). Garde et al. describe EHRs as having the following necessary characteristics:

  • Patient-Centred: The EHR relates to the patient, not an encounter with an institution.

  • Longitudinal: A long-term record of patient care.

  • Comprehensive: Record of care from all health care providers and institutions.

  • Prospective: Plans, goals, orders, and evaluations are recorded (Garde, Knaup, Hovenga, & Heard, 2007).

Conceptually, PHRs are digital health information vehicles that can be managed by individuals (patients or surrogates) compared to EHRs that are managed by health providers or clinical institutions. Although there is no absolute consensus on what defines PHRs, a description suggested by the Markle Foundation’s working group on policies for information sharing between doctors and patients is useful. It describes PHRs as: “an electronic application through which individuals can access, manage and share their health information...in a private, secure and confidential environment” (Markle Connecting for Health, 2004). The National Alliance for Health Information Technology further clarifies an idealized model of PHRs as “an electronic record of health-related information that conforms to a common interoperability standard allowing information to be drawn from multiple sources while being managed, shared and controlled by the individual” (Kahn, Aulakh, & Bosworth, 2009, p. 369).

There is a range of formats that PHRs can be classified. The simplest is a stand-alone patient-initiated application that is not linked with any other system. The patient enters their own health data using commercial applications. Google Health and Microsoft Health Vault are examples of companies that have introduced such systems. However there is a concern that patients would not keep records up to date in a stand-alone PHR (Tang et al., 2006). Consequently these PHRs could be unreliable instruments for conveying information to clinicians or health institutions. Tang, et al. suggest that although some information can be supplied by patients, clinicians must have access to their own past inputs to assist in decision making. They stated; “[T]he reliability of patient-entered data depends on the nature of the information per se, the patient’s general and health literacy, and the specific motivations for recording the data.” (Tang et al., 2006, p. 122) In a study conducted by Ira C. Denton, 1000 patients were offered their medical information in a stand-alone PHR system. Only 330 accepted. After 10 months, of those who responded to a survey, 37% continued to use the electronic record (Denton, 2001). According to Linda Reed, chief information officer, Atlantic Health; “[M]any people are more willing to keep their Facebook page updated than their medical records” (Page, 2010).
