Leveraging point-of-care clinician feedback to study barriers to guideline adherence.
Studies of barriers to guideline adherence have generally surveyed clinicians temporally remote from the clinical scenario in which recommendations were delivered, potentially adversely biasing clinician observations. The user interface of ATHENA DSS, a guideline-based decision support system for hypertension, includes a point-of-care feedback window that accepts clinician-user comments during the display of recommendations. Analysis of this feedback has revealed a number of intriguing patient, provider, and technical barriers to adherence collected during real-time system use.

Randomized Controlled Trial Comparative StudyEvaluation of CoViSTA - an automated vital sign documentation system - in an inpatient hospital setting.
The aim of this study was to compare the efficiency and acceptance of the CoViSTA system with the current practice of collecting vital signs. CoViSTA (Computerized Vital Sign Transfer Application) was designed to integrate with the existing hospital network and automate the process of vital sign data entry in hospital wards. The system was evaluated with 6 nurses across 60 patients and was found to significantly reduce errors, improve efficiency and increase satisfaction among the staff.

ReviewA systematic review of user interface issues related to PDA-based decision support systems in health care.
This paper explores user interface issues in the design and implementation of a personal digital assistant-based decision support system (PDA-DSS) in health care. An automated literature search found 15 studies addressing the main PDA user interface issues, which can be categorized as display, security, memory, Web browser, and communication.

Comparative Study Controlled Clinical TrialEfficiency, comprehensiveness and cost-effectiveness when comparing dictation and electronic templates for operative reports.
Surgeons typically document operative events using dictation services. Dictated reports are frequently incomplete or delayed. Electronic note templates could potentially improve this process. ⋯ Templates increased overall compliance with national standards for operative note documentation and avoided transcription costs. Documentation with templates took slightly more time than dictation (mean 6.77 v. 5.96 minutes; P=0.036), not including the additional time necessary to subsequently verify dictated reports. We conclude that electronic note templates can improve the timeliness and comprehensiveness of operative documentation, while decreasing transcription costs and requiring minimal additional effort on the part of surgeons.

Bayesian Communication provides an explicit and quantitative way to combine a reader's preconceived notions with data from a study to help in making decisions, and thus implements the decision-analytic paradigm in the setting of interpreting and adapting research results. Article Assistant employs a three-tier architecture. The interface elicits users' prior belief and values; the article library provides data from the study, the system calculates the posterior belief distribution and sensitivity analysis on the fly, and provides an interpretation of the numerical results.
