Understanding usage patterns of handheld computers in clinical practice.
(9/421)
Handheld computers are commonly used in clinical practice and often considered invaluable by physicians. Though full of promise, the technology is still costly and literature assessing its real use in clinical practice remains scarce. In an effort to better understand how Personal Digital Assistants (PDA) can be utilized as clinical tools, we designed a study that closely monitored the use of a selection of handheld applications by a cohort of interns in a service of Internal Medicine. Information gathered about actual use of the mobile applications offer valuable insights on usage patterns of tools that promise to be become an important part of our clinical practice in the years to come, and will hopefully help guide future developments.

Handheld computing in medicine.
(10/421)
Handheld computers have become a valuable and popular tool in various fields of medicine. A systematic review of articles was undertaken to summarize the current literature regarding the use of handheld devices in medicine. A variety of articles were identified, and relevant information for various medical fields was summarized. The literature search covered general information about handheld devices, the use of these devices to access medical literature, electronic pharmacopoeias, patient tracking, medical education, research, business management, e-prescribing, patient confidentiality, and costs as well as specialty-specific uses for personal digital assistants (PDAs). The authors concluded that only a small number of articles provide evidence-based information about the use of PDAs in medicine. The majority of articles provide descriptive information, which is nevertheless of value. This article aims to increase the awareness among physicians about the potential roles for handheld computers in medicine and to encourage the further evaluation of their use. (+info)
Personal digital assistant infectious diseases applications for health care professionals.
(11/421)
Personal digital assistants (PDAs; also known as "handheld computers," "pocket personal computers," and Palm Pilots) provide immediate access to vital and clinically relevant infectious diseases information at the point of care. Several infectious diseases applications are available that provide information on pathogens, diagnosis, medication, and treatment. In this article, 4 infectious diseases PDA applications are reviewed: ePocrates ID (part of ePocrates Rx Pro), the Johns Hopkins Division of Infectious Diseases Antibiotic Guide, the 2002 Sanford Guide to Antimicrobial Therapy, and Infectious Diseases and Antimicrobials Notes. Drug information, including clinical pharmacology, dosing in patients with renal insufficiency, adverse reactions, and drug interactions, is evaluated for completeness and accuracy by comparison of each application with the package insert. Treatment recommendations for 6 diseases are compared with current practice guidelines. Each PDA infectious diseases application reviewed has unique advantages and disadvantages. This critical review will help health care professionals select the infectious diseases PDA application best tailored to meet their individual information needs. (+info)
Personal digital assistants herald new approaches to teaching and evaluation in medical education.
(12/421)
Since its arrival in 1994, the personal digital assistant (PDA) has made significant inroads in the handheld industry, with 50% of physicians anticipated as users by 2005 due to its functionality as a point-of-care medical informatics tool. However, its use in medical education is less well documented. Since 1998, PDAs have been used at Medical College of Wisconsin (MCW) as both a teaching and an evaluation tool for medical student and resident education. This article highlights the use of the PDA in medical education and describes current applications for monitoring clinical experiences of students/residents, and teaching resources for hypertension, cardiac auscultation, and community health. MCW's experiences with the PDA as a real time teaching and data collection tool serves as a model for other medical schools and for our students who are educated in the importance of self-monitoring one's clinical experiences and the need for continuous improvement as future physicians.

(13/421)
This paper describes an overview and illustrative example for creating a portable data-collection system using Microsoft Embedded Visual Tools for the Pocket PC. A description of the Visual Basic programming language is given, along with examples of computer code procedures for developing data-collection software. Program specifications, strategies for customizing the collection system, and troubleshooting tips are also provided. (+info)
Survey assessment of personal digital assistant use among trainees and attending physicians.
(14/421)
Limited information is available on personal digital assistant (PDA) use patterns in medical settings. Recognizing that use patterns may be important considerations for development of handheld-based information systems, the authors characterized PDA use at their institution. A survey was mailed to all internal medicine physicians at the Mayo Clinic, Rochester, Minnesota, in May 2002. PDA use prevalence, user demographics, hardware preferences, and work setting and application use frequencies were assessed for respondents reporting current PDA use. Use patterns of trainees (residents and subspecialty fellows) and attending physicians were compared. Trainees reported more frequent PDA use in the hospital setting and for direct patient care. Attending physicians reported more frequent PDA use in administrative settings and for calendar functions. These findings may reflect differences in the information needs and work roles of learners and experienced physicians. Such factors may be important considerations for the development and implementation of institutional PDA resources. (+info)
PalmCIS: a wireless handheld application for satisfying clinician information needs.
(15/421)
Wireless handheld technology provides new ways to deliver and present information. As with any technology, its unique features must be taken into consideration and its applications designed accordingly. In the clinical setting, availability of needed information can be crucial during the decision-making process. Preliminary studies performed at New York Presbyterian Hospital (NYPH) determined that there are inadequate access to information and ineffective communication among clinicians (potential proximal causes of medical errors). In response to these findings, the authors have been developing extensions to their Web-based clinical information system including PalmCIS, an application that provides access to needed patient information via a wireless personal digital assistant (PDA). The focus was on achieving end-to-end security and developing a highly usable system. This report discusses the motivation behind PalmCIS, design and development of the system, and future directions.

Randomised controlled trial of clinical decision support tools to improve learning of evidence based medicine in medical students.
(16/421)
OBJECTIVE: To assess the educational effectiveness on learning evidence based medicine of a handheld computer clinical decision support tool compared with a pocket card containing guidelines and a control. DESIGN: Randomised controlled trial. SETTING: University of Hong Kong, 2001. PARTICIPANTS: 169 fourth year medical students. MAIN OUTCOME MEASURES: Factor and individual item scores from a validated questionnaire on five key self reported measures: personal application and current use of evidence based medicine; future use of evidence based medicine; use of evidence during and after clerking patients; frequency of discussing the role of evidence during teaching rounds; and self perceived confidence in clinical decision making. RESULTS: The handheld computer improved participants' educational experience with evidence based medicine the most, with significant improvements in all outcome scores. More modest improvements were found with the pocket card, whereas the control group showed no appreciable changes in any of the key outcomes. No significant deterioration was observed in the improvements even after withdrawal of the handheld computer during an eight week washout period, suggesting at least short term sustainability of effects. CONCLUSIONS: Rapid and convenient access to valid and relevant evidence on a portable computing device can improve learning in evidence based medicine, increase current and future use of evidence, and boost students' confidence in clinical decision making.
