Giving Patients Granular Control of Personal Health Information: Using an Ethics ‘Points to Consider’ to Inform Informatics System Designers

Objective
There are benefits and risks of giving patients more granular control of their personal health information in electronic health record (EHR) systems. When designing EHR systems and policies, informaticists and system developers must balance these benefits and risks. Ethical considerations should be an explicit part of this balancing. Our objective was to develop a structured ethics framework to accomplish this.

Methods
We reviewed existing literature on the ethical and policy issues, developed an ethics framework called a “Points to Consider” (P2C) document, and convened a national expert panel to review and critique the P2C.

Potential application of item-response theory to interpretation of medical codes in electronic patient records

Dregan A et al, BMC Medical Research Methodology, 11

BACKGROUND
Electronic patient records are generally coded using extensive sets of codes but the significance of the utilisation of individual codes may be unclear. Item response theory (IRT) models are used to characterise the psychometric properties of items included in tests and questionnaires. This study asked whether the properties of medical codes in electronic patient records may be characterised through the application of item response theory models.

Use and Satisfaction with Electronic Health Record by Primary Care Physicians in a Health District in Brazil

Holanda AA et al, Journal of Medical Systems, 2011

It is believed that Electronic Health Records (EHR) improve not only quality of care but also patient safety and health care savings. This seems to be true for developed countries but not necessarily in emerging economies. This paper examined the primary care physicians’ satisfaction with a specific EHR in a health district of a major city in Brazil and describes how they are using it as well as its specific functions. A cross-sectional questionnaire survey with all physicians from all Community Health Centers of the 6th health district of the City of Fortaleza that were using HER was conducted. From the 111 subjects (100%), a total of 99 physicians answered the survey (89% response rate). For overall satisfaction with the EHR, 2 (2%) were satisfied, 50 (50.5%) were satisfied in part and 47 (47.5%) were not satisfied.

Extraction of standardized archetyped data from Electronic Health Record systems based on the Entity-Attribute-Value Model

Duftschmid G et al, International Journal of Medical Informatics, 2010

Objective
The ISO/EN 13606 Electronic Health Record architecture standard permits semantically interoperable exchange of Electronic Health Record data by using archetypes to define the structure and semantics of Electronic Health Record contents. Practical implementations of the ISO/EN 13606 standard have been scarcely reported on, and none of the publications describes in detail an efficient technique of archetype-compliant data extraction from an Electronic Health Record system. We address this research issue in the present report, and focus on a specific class of largely research-oriented Electronic Health Record systems which are internally based on the Entity-Attribute-Value Model.

A piece of my mind. Copy-and-paste

Hirschtick RE. JAMA, 295(20)

The electronic medical record (EMR) arrived at our teaching hospital one year ago and the resultant changes in medical student and physician notes have been remarkable. While EMR is highly efficient in producing notes, virtually all of its notes are longer, recombinant versions of previous notes. Even notes of different authors are morphed by EMR into clones of one another. As physicians have become more adept with the time-saving features of EMR, their notes have been rendered incapable of conveying usable information by their bloated and obfuscated nature.

Implementation of the Veterans Health Administration VistA clinical information system around the world

Protti, Denis, and Peter Groen, ElectronicHealthcare, 7(2)

The success story of the Veterans Health Administration (VHA) within the US Department of Veterans Affairs has been well documented and is generally well known. What is generally not known is that the VHA’s clinical information system, known as VistA, and the computerized patient record system clinical user interface front end have been successfully transported and implemented to a number of non-VHA healthcare organizations across the United States.

Measuring the impact of the computer on the consultation: An open source application to combine multiple observational outputs

Pflug, Bernhar et al, Informatics for Health and Social Care, 35(1)

A diverse range of tools and techniques can be used to observe the clinical consultation and the use of information technology. These technologies range from transcripts; to video observation with one or more cameras; to voice and pattern recognition applications. Currently, these have to be observed separately and there is limited capacity to combine them. Consequently, when multiple methods are used to analyse the consultation a significant proportion of time is spent linking events in one log file (e.g. mouse movements and keyboard use when prescribing alerts appear) with what was happening in the consultation at that time. The objective of this study was to develop an application capable of combining and comparing activity log-files and with facilities to view simultaneously all data relating to any time point or activity. Interviews, observations and design prototypes were used to develop a specification. Class diagram of the application design was used to make further development decisions. The application development used object-orientated design principles. We used open source tools; Java as the programming language and JDeveloper™ as the development environment. The final output is log file aggregation (LFA) tool which forms part of the wider aggregation of log files for analysis (ALFA) open source toolkit (www.biomedicalinformatics.info/alfa/).

[Cooperation with the electronic medical record and accounting system of an actual dose of drug given by a radiology information system]

By input of the actual dose of a drug given into a radiology information system, the system converting with an accounting system into a cost of the drug from the actual dose in the electronic medical record was built. In the drug master, the first unit was set as the cost of the drug, and we set the second unit as the actual dose. The second unit in the radiology information system was received by the accounting system through electronic medical record. In the accounting system, the actual dose was changed into the cost of the drug using the dose of conversion to the first unit.

Critical areas of national electronic health record programs-Is our focus correct?

Deutsch, Eva et al, International Journal of Medical Informatics, 79(3)

Objective
National electronic health record programs are frequently associated with a number of problems. In view of their long duration and costs, efficient implementation of the programs with due regard given to the conclusions drawn thus far would be a meaningful goal from the economic point of view. In the present report we analyze programs from various countries with regard to the problems documented therein and derive, on a cross-country basis, the most common critical aspects of national electronic health record programs. These aspects should be given special attention in the implementation of future national electronic health record programs. Furthermore, measures which have proven to be useful in coping with the respective problems in individual countries will be suggested for each critical area.

Medical student documentation in the medical record: is it a liability?

Gliatto, Peter, Philip Masters, and Reena Karani, The Mount Sinai Journal of Medicine, 76(4)

Medical students have routinely documented patient encounters in both inpatient and outpatient care venues. This hands-on experience has provided a way for students to reflect on patient encounters, learn proper documentation skills, and attain a sense of being actively involved in and responsible for the care of patients. Over the last several years, the practice of student note writing has come into question. Institutional disincentives to student documentation include insurance regulations that restrict student documentation from substantiating billing claims, concerns about the legal status of student notes, and implementation of electronic medical records that do not allow or restrict student access.
