T he Crosson et al1 and Koopman et al 2 articles in this issue provide excellent illustrations and validation of the need for a systematic approach to make health information technology (HIT) safe and effective for use within health care. These studies can be viewed in this comprehensive context through the lens of a recently developed 8-dimension, sociotechnical model of HIT use.3,4 Briefl y, this model offers a systems-level view and posits that all 8 of the interconnected dimensions of HIT must be adequately addressed if an organization is to achieve safe and effective electronic health record use. Failure to account for key items in any one of these dimensions can lead to almost insurmountable problems within the clinic.The fi rst aspect of this model, and the foundation of any e-prescribing or other HIT project, is represented by the hardware and software, which provide the features and functions the clinicians and offi ce staff use to carry out the data entry, review, and transmission processes required to document their patient care activities. Crosson et al found in their observations that clinics required considerable on-site technical resources to help them implement and maintain the required technical infrastructure.The clinical content required to implement the medication lists, drug dictionaries, formulary and billing information, and medication history, along with the drug-drug interaction checks, represents the second dimension of the model. The Koopman et al article provides an excellent overview of the detailed clinical knowledge (ie, content) that must be collected, managed, and effectively brought to bear at the right point in the clinical workfl ow to help clinicians solve complex patient care problems.
5The human-computer user interface, the third dimension, is critical. The article by Koopman et al describes an effective, highly specialized, conditionspecifi c, human-computer interface developed to help clinicians in an ambulatory setting quickly and efficiently fi nd all the information they need to provide high-quality diabetes care.Certain special and essential personnel, represented by the fourth dimension, are required to design, develop or confi gure, implement, use, and evaluate all aspects of the HIT. The Koopman et al article highlights how clinically focused, human-computer interface evaluation experts can help clinicians evaluate new system functionality. The Crosson et al article illustrates the different skills and knowledge that are required to plan successfully (eg, clinical champions or opinion leaders), implement (eg, technical resources), and use (eg, superusers) such new HIT functions as e-prescribing. Often the incorporation of team members with complementary knowledge, skills, and experience can greatly improve the quality of the research
