evaluation studies

Direct text entry in electronic progress notes. An evaluation of input errors

Weir CR et al, Methods of Information in Medicine, 42(1)

It is not uncommon that the introduction of a new technology fixes old problems while introducing new ones. The Veterans Administration recently implemented a comprehensive electronic medical record system (CPRS) to support provider order entry. Progress notes are entered directly by clinicians, primarily through keyboard input. Due to concerns that there may be significant, invisible disruptions to information flow, this study was conducted to formally examine the incidence and characteristics of input errors in the electronic patient record.

Socio-technical considerations in epilepsy electronic patient record implementation

Examination of electronic patient record (EPR) implementation at the socio-technical interface. This study was based on the introduction of an anti-epileptic drug (AED) management module of an EPR in an epilepsy out-patient clinic. The objective was to introduce the module to a live clinical setting within strictly controlled conditions to evaluate its usability and usefulness.

Using heuristic evaluations to assess the safety of health information systems

Carvalho, Christopher J. et al, Advances in Information Technology and Communication in Health, 2009

Health information systems (HISs) are typically seen as a mechanism for reducing medical errors. There is, however, evidence to prove that technology may actually be the cause of errors. As a result, it is crucial to fully test any system prior to its implementation. At present, evidence-based evaluation heuristics do not exist for assessing aspects of interface design that lead to medical errors. A three phase study was conducted to develop evidence-based heuristics for evaluating interfaces. Phase 1 consisted of a systematic review of the literature. In Phase 2 a comprehensive list of 33 evaluation heuristics was developed based on the review that could be used to test for potential technology induced errors. Phase 3 involved applying these healthcare specific heuristics to evaluate a HIS.

Evaluating inter-professional work support by a computerized physician order entry (CPOE) system

Niazkhani, Zahra et al, eHealth Beyond the Horizon - Get IT There, 2008

Physician-centered design for computerized physician order entry (CPOE) systems overlooks the collaborative, multi-professional nature of medical work. We analyzed the compatibility of the conceptual model of inter-professional workflow underlying a CPOE system with real-life workflow in the medication ordering and administration process. We conducted twenty-three semi-structured interviews with key informant users and analyzed the handwritten documents and computerized printouts used in daily work in a Dutch academic medical center.

Tensions associated with the use of electronic knowledge resources within clinical decision-making processes: A multiple case study

Mysore, N. et al, International Journal of Medical Informatics, 78(5)

Content and objective
Health professionals now routinely use electronic knowledge resources (EKRs). Few studies have considered EKR-related tensions which may arise in a clinical decision-making context. The present study aims to explore three types of tension: (1) user-computer tension, (2) social tensions, and (3) organizational tensions (constraints associated with organizational routines and health policies).

Same system, different outcomes: Comparing the transitions from two paper-based systems to the same computerized physician order entry system

Niazkhani, Zahra et al, International Journal of Medical Informatics, 78(3)

To compare how nurses in two different paper-based systems perceive the impact of a computerized physician order entry (CPOE) system on their medication-related activities.

13 non-surgical, adult inpatient wards in a Dutch academic hospital.

STARE-HI–Statement on reporting of evaluation studies in Health Informatics

Talmon, Jan et al, International Journal of Medical Informatics, 78(1)

Development of guidelines for publication of evaluation studies of Health Informatics applications.

An initial list of issues to be addressed in reports on evaluation studies was drafted based on experiences as editors and reviewers of journals in Health Informatics and as authors of systematic reviews of Health Informatics studies, taking into account guidelines for reporting of medical research. This list has been discussed in several rounds by an increasing number of experts in Health Informatics evaluation during conferences and by using e-mail and has been put up for comments on the web.

Teleconsultation in remote care stations: cost-minimisation analysis of the Guianese experiment

Nassiri, N. et al, International Journal of Biomedical Engineering and Technology, 2(1)

The aim of the paper is to carry out a cost-minimisation analysis in order to measure the cost saving performances of teleconsultation in Guiana. Fixed and variable costs are estimated in order to identify the break-even point of teleconsultation. It also takes into account organisational and quality effects.

Formative evaluation: a critical component in EHR implementation

McGowan, Julie J. et al, J Am Med Inform Assoc, 15(3)

This Viewpoint paper has grown out of a presentation at the American College of Medical Informatics 2007 Winter Symposium, the resulting discussion, and several activities that have coalesced around an issue that most informaticians accept as true but is not commonly considered during the implementation of Electronic Health Records (EHR) outside of academia or research institutions. Successful EHR implementation is facilitated and sometimes determined by formative evaluation, usually focusing on process rather than outcomes.

Examination of instruments used to rate quality of health information on the internet: chronicle of a voyage with an unclear destination

Gagliardi, Anna, and Alejandro R. Jadad, BMJ, 324(7337)

This study updates work published in 1998, which found that of 47 rating instruments appearing on websites offering health information, 14 described how they were developed, five provided instructions for use, and none reported the interobserver reliability and construct validity of the measurements.

A proposed benefits evaluation framework for health information systems in Canada

Lau, Francis et al, ElectronicHealthcare, 5(1)

This article describes a benefits evaluation framework for the health information systems currently being implemented across Canada through Canada Health Infoway with its jurisdictional partners and investment programs. This framework is based on the information systems success model by DeLone and McLean, the empirical analysis by van der Meijden on the use of this model in the health setting and our own review of evaluation studies and systematic review articles in health information systems.
