Use Of Personal Digital Assistants Research Articles

Use of personal digital assistants for retrieval of medical images and data on high-resolution flat panel displays.

For its new acute care hospital, the University of California at Los Angeles is evaluating innovative technology involving high-resolution flat panel display devices configured as "network appliances" that can be wall mounted for use in the retrieval and display of medical images and data. Physicians and healthcare providers can log on with wireless handheld computers, which can serve as an identification device as well as a navigational tool for selecting patient records and data. These data are displayed and manipulated on the flat panel display without the need for a keyboard or mouse. A prototype was developed with commercially available image display software, which was modified to allow the remote control of software functions from a handheld device through an infrared communication port. The system also allows navigation through the patient data in a World Wide Web-based electronic patient record. This prototype illustrates the evolution of radiologic facilities toward "shareable" high-quality display devices that allow more convenient and cost-effective access to medical images and related data in complex clinical environments, resulting in a paradigm shift in data navigation and accessibility.

Reducing errors in discharge medication lists by using personal digital assistants.

This study examined whether the number of errors in discharge medication lists at a psychiatric hospital would decrease when the practice of transcribing the lists by hand from physicians' discharge orders was replaced by the use of personal digital assistants (PDAs) to create and directly print out such lists. In a four-month period before the use of PDAs was introduced, 20 of the 110 hand-transcribed lists (22 percent) contained errors. In the four-month period after the use of PDAs was implemented, seven of the 90 PDA-generated lists (8 percent) contained errors. Use of a PDA may be helpful in providing safer patient care.

Using personal digital assistants for pain management

Healthcare workers involved in hospital- or office-based practices are constantly collecting, retrieving and assimilating information related to their patients. The personal digital assistant (PDA) is a perfect tool to assist in this task. Communication of the PDA with desktop computers not only increases its power, but protects data from loss and allows for more sophisticated manipulation or utilization of the data. This article focuses on the use of PDA's in medicine and specifically on how database programs can be used in a postoperative pain management practice. Copyright 2002, Elsevier Science (USA).

Using personal digital assistants to access drug information.

The use of personal digital assistants (PDAs) to access drug information in a health system is described. Given the widespread use of PDAs at an 872-bed university health system, an opportunity existed to provide current drug information to physicians via these devices. As part of the health system's intranet, extensive online content had been made available through a browser; extension to PDAs was a natural next step. There were two primary requirements: the ability to synchronize information with the database server when a PDA was used and the development of content and applications by using existing staff. Mobile enterprise software was chosen that supports multiple PDA platforms, is easy to use, and does not require programming skills. The software works through customized "channels," or collections of information from a content provider. The customized channel service works over the Internet. Two channels of content were created, an ambulatory care channel and an inpatient care channel. The ambulatory care channel contains a list of preferred ambulatory care agents, poison control information, the locations of outpatient pharmacies, drug information, and safety tips for prescribing. The inpatient channel contains the inpatient formulary, current news and events, information on currrent drug shortages and recalls, pharmacy contact information, and medication safety tips. When a user synchronizes his or her PDA, the software contacts the department's intranet servers and processes the request. The data are compressed and downloaded to the user's PDA. A university health system successfully used PDAs to access drug and other information.

Use of personal digital assistants to enhance educational evaluation in a primary care clerkship

Experiences of students using optically scanned cards were compared with those of students using personal digital assistants (PDAs) to log patient encounters in a primary care clerkship. From April to September 2001, students were offered the option of using a PDA in lieu of scanned cards to track clinical encounters. Data obtained from PDA users were compared with those previously obtained from scanned card users. Verbal and written feedback was obtained from all students. Of the 71 students invited to participate, 21 (30%) owned a PDA, and of these, 20 agreed to participate. Eighteen students completed the pilot. One student was unable to participate owing to software installation problems; another student lost data because of improper back-up. Students using the PDAs recorded more encounters per rotation and had fewer missing data when compared with students who used scanned card. Additionally, feedback from students suggested that PDAs offered other important educational benefits.

Reading with new tools: An evaluation of Personal Digital Assistants as tools for reading course materials

Lightweight, palmtop devices such as personal digital assistants (PDAs) can now be used for reading electronic text, opening up their potential as learning tools. This paper reports a study that evaluated the use of PDAs for reading course materials by students on an Open University master's course. The research is grounded in activity theory, which provides a useful framework for examining how the introduction of a new tool changes an existing activity. Student perceptions of the possibilities and constraints of the PDA, as determined by questionnaires and interviews, reveal the impact the new tool had upon reading. The PDA constrained reading with limitations such as the small screen size, new requirements for navigating through the text and awkward methods for taking notes. These conditions made it difficult for students to skim-read the text, to move back and forth within the document and to interact with the text as easily as they could with paper. Nevertheless, students welcomed the opportunity to have the course materials on a portable, lightweight device that could be used at any time and in any place. This made it easier to fit the reading activity around the various other activities in which students were involved In addition, the PDA was used in conjunction with existing tools, such as the printed version of the course materials and the desktop computer. Therefore, it was not seen to replace paper but rather to extend and complement it. The findings are discussed using concepts from activity theory to interpret how the new tool modified the reading activity.DOI:10.1080/0968776020100205

Information and communication technologies and health in low income countries: the potential and the constraints.

This paper outlines the potential offered by technological progress in the information and communication technologies (ICTs) industries for the health sector in developing countries, presents some examples of positive experiences in India, and considers the difficulties in achieving this potential. The development of ICTs can bring about improvements in health in developing countries in at least three ways: as an instrument for continuing education they enable health workers to be informed of and trained in advances in knowledge; they can improve the delivery of health and disaster management services to poor and remote locations; and they can increase the transparency and efficiency of governance, which should, in turn, improve the availability and delivery of publicly provided health services. These potential benefits of ICTs do not necessarily require all the final beneficiaries to be reached directly, thus the cost of a given quantum of effect is reduced. Some current experiments in India, such as the use of Personal Digital Assistants by rural health workers in Rajasthan, the disaster management project in Maharashtra and the computerized village offices in Andhra Pradesh and Pondicherry, suggest creative ways of using ICTs to improve the health conditions of local people. However, the basic difficulties encountered in using ICTs for such purposes are: an inadequate physical infrastructure; insufficient access by the majority of the population to the hardware; and a lack of the requisite skills for using them. We highlight the substantial cost involved in providing wider access, and the problem of resource allocation in poor countries where basic infrastructure for health and education is still lacking. Educating health professionals in the possible uses of ICTs, and providing them with access and "connectivity", would in turn spread the benefits to a much wider set of final beneficiaries and might help reduce the digital divide.

Ethics

Both teachers and students benefit from an interactive classroom. The teacher receives valuable input about effectiveness, student interest, and comprehension, whereas student participation, active learning, and enjoyment of the class are enhanced. Cost and deployment have limited the use of existing audience response systems, allowing anonymous linking of teachers and students in the classroom. These limitations can be circumvented, however, by use of personal digital assistants (PDAs), which are cheaper and widely used by students. In this study, the authors equipped a summer histology class of 12 students with PDAs and wireless Bluetooth cards to allow access to a central server. Teachers displayed questions in multiple-choice format as a Web page on the server and students responded with their PDAs, a process referred to as polling. Responses were immediately compiled, analyzed, and displayed. End-of-class survey results indicated that students were enthusiastic about the polling tool. The surveys also provided technical feedback that will be valuable in streamlining future trials.
