An X Window system for statlab results reporting.
We have developed a system that receives "stat" results encoded in Health Level Seven from the Laboratory Information System, prints a report in destination Intensive Care Units (ICUs), and captures the data for review in a custom spreadsheet format at color X-terminals located in ICUs. Available services include a reference nomogram plot of arterial blood gas data, printed summaries, automated access to the Clinical Information System and a Medline database, electronic mail, a simulated electronic calculator, and general news and information. Security mechanisms include an audit trail of user activities on the system. Noteworthy technical aspects and non-technical factors impacting success are discussed.

Linguistic analysis: terms and phrases used by patients in e-mail messages to nurses.
While some researchers are focusing on mapping free-text within health care fields into controlled vocabularies and classifications, many researchers are focusing on consumers' vocabularies. Using natural language processing (NLP) tools, such as MetaMap, to extract and map into terms in a controlled vocabulary is one way of understanding the pattern of terms used by lay people. Before an NLP tool can be effectively and efficiently used to extract concepts and create machine-understandable interpretations of the data, the appropriateness of the tool needs to be determined. This study aims were to determine the appropriateness of linguistic meaning captured for terms and phrases used by patients in electronic mail messages to nurses, using nursing-specific MetaMap output. Twenty messages were randomly selected from the 241 messages data set. Results indicated that four out of six nursing classification systems captured more than 50 % of the parsed word's linguistic meaning. This study demonstrates that it is possible to automatically extract and capture the linguistic meaning of the terms patients use in their electronic mail messages.

Access and use of the internet in a hand surgery population.
Internet use is increasing and its applications to medicine and patient information are widening daily. Previous studies have focused on the quality and quantity of medical information on the Internet. The current study focuses on a population of 120 new patients presenting to a hand surgery practice. A questionnaire was used to analyse patterns of Internet access, use of the Internet to look up personal symptoms, and patients' opinions on the use of electronic mail by office staff. Results showed that approximately 90% of the group had some form of Internet access, with a significant age-related decrease in Internet access. Only 17% used the Internet to look up their symptoms, but this group was more likely to correctly match their self-diagnosis to the surgeon's diagnosis. On average, 65% of the study group favoured the use of electronic mail for office staff's communications with patients.

The physician and the Internet.
The Internet is one of the greatest developments in informational exchange during the past century. It allows almost anyone to access information available throughout the world. Nonetheless, the Internet is often misunderstood by physicians. It can be considered a super computer network that allows users to transfer a wide variety of information at a low cost. The information can be transferred through functions such as electronic mail, file transfer protocols, the Usenet, or the most widely recognized World Wide Web. Electronic mail functions like the usual postal service but is carried through the Internet, and delivery is usually within the hour. It can serve as a method of communication between physicians and patients. File transfer protocols function as a method for transferring large amounts of information such as software through the Internet. The Usenet acts like an international bulletin board service, allowing users anywhere to post messages and to respond to messages from other users. Several patient support groups have Usenet sites for exchanging specific disease information. The World Wide Web has received the greatest attention because most of the information on the Internet is text, sound, or pictures. Numerous medical organizations have established Web sites. This article attempts to describe each of these functions and the benefits to physicians.

Development and evaluation of an electronic drug and therapeutics bulletin.
OBJECTIVE: To describe the development, implementation, and initial evaluation of a paperless drug and therapeutics bulletin that is distributed by electronic mail from the pharmacy department of an Australian teaching hospital. OUTCOMES: A standardized format for the bulletin was designed and approved in February 2001. The aim of the bulletin is to facilitate the timely dissemination of concise, factual information about issues of current interest in therapeutics, drug safety, and the cost-effective use of medicines. A simple and attractive graphic design was chosen, and the hospital's clinical pharmacists and drug information staff developed an initial bank of content during the period immediately preceding the launch. The bulletin is presented as a 1-page, read-only file in Word for Windows format and was initially distributed by electronic mail to all users of the hospital's computerized communication network. As the popularity of the bulletin increased, healthcare practitioners from outside of the hospital began to request permission for inclusion on the circulation list, and the content was frequently forwarded by E-mail to workers in other hospitals and community-based settings. The bulletin is now distributed to pharmacists around Australia via 2 separate moderated discussion lists, one of which provides an archive site for previous editions. Healthcare workers in Singapore, the US, Canada, and New Zealand also receive the bulletin, which is now also abstracted by a major Australian pharmacy journal. A readership survey (also electronically distributed) was used to seek feedback after the publication of the first 12 editions. Readers indicated a high level of satisfaction with the content, format, and frequency of distribution of the materials. CONCLUSIONS: Although the concept and execution of this project was relatively simple, an extensive literature review did not reveal any previously published reports describing this type of approach to the distribution of a pharmacy bulletin. The development and implementation of the electronic drug and therapeutics bulletin has provided an opportunity to use modern communication technology to promote safe and effective medication use and appears to have been well received.

Use of telemedicine in periodic screening of diabetic retinopathy.
Telemedicine was used for taking ocular fundus images of diabetic patients, which were subsequently sent by electronic mail to experienced ophthalmologists at a university hospital. The ophthalmologists provided reports on the patients to the internists. The objective of the study was to evaluate the effectiveness of this telemedicine system. A total of 279 diabetic patients were admitted to the Third Department of Internal Medicine of Yokohama City University Hospital, School of Medicine, for blood sugar control or for education on lifestyle between April, 1999, and October, 2000. The subjects did not have eye disease nor diabetic retinopathy when evaluated by an ophthalmologist (at either Yokohama City University Hospital or other facility) within 3 months before enrollment in the study. After dilation of the pupil, fundus images were taken of each eye from four angles using a nonmydriatic fundus camera. The images were transmitted by electronic mail to the Division of Ophthalmology of Tokyo University Branch Hospital along with other patient information. The ophthalmologists there evaluated the images on the screen according to Fukuda's classification of diabetic retinopathy. They sent ophthalmologic reports to the internists at the Third Department of Internal Medicine of Yokohama City University Hospital, School of Medicine, and recommended whether the patient should be seen by his/her regular ophthalmologist earlier than the next scheduled visit. Fundus images were obtained at the time of admission, at 1, 3, and 6 months after discharge, and at every 6 months thereafter. Out of the images of 1170 eyes obtained at various time points from the 279 patients, 1076 (92.0%) were successfully evaluated by the ophthalmologists at the University of Tokyo, while 60 (5.1%) could not be evaluated and there was a communication problem for the images of 34 eyes. The ophthalmologists determined that 5 eyes of 3 patients required further evaluation by the patient's regular ophthalmologist based on the images transferred by telemedicine. No patient dropped out during the study period.

Mechanisms for exchange of image data to support distant medical consultation.
The VA has developed an integrated infrastructure to support the exchange of medical data, including images and text report data, between medical centers. This capability is expected to support teleconsulting and meet a variety of existing medical staffing and consultation needs. Consultation from distant locations requires at least the same complete integrated patient record available to onsite physicians. Several mechanisms are being explored to support distant medical consultation. Multimedia extensions to the VA's electronic mail system have been developed to allow images and other data objects to be included in electronic mail messages. Another approach that has been prototyped is to extend existing local imaging networks to produce more widely distributed imaging systems. These approaches will be described and discussed.

Trends in ureteropelvic junction obstruction management among urologists in the United States.
OBJECTIVES: To determine current practice patterns in the surgical treatment of ureteropelvic junction obstruction (UPJO) among urologists in the United States. METHODS: Using the American Urological Association directory, an electronic mail survey regarding the surgical management of UPJO was sent to 1040 urologists in the United States with an electronic mail address listed in the roster. RESULTS: The response rate was 37.6%. Of the respondents, 67.4% were in community practice and 32.6% in academic practice. Nearly 53% of the respondents would perform a workup for a crossing vessel before definitive therapy; if no crossing vessel was found, 43.5% would consider Acucise endopyelotomy as the first-line procedure. However, if a crossing vessel was found, 57.4% would perform open pyeloplasty and 34.3% would choose laparoscopic pyeloplasty as their first-line procedure. If pyeloplasty was chosen, community urologists preferred open pyeloplasty (77.6%), and academic urologists preferred laparoscopic pyeloplasty (66.9%). The surgeon's training and experience was the most influential factor in choosing between laparoscopic and open pyeloplasty. If the patient had a failed endopyelotomy in the past, most respondents (90.8%) would perform pyeloplasty for definitive treatment of the UPJO. CONCLUSIONS: Demonstration of a crossing vessel remains an important factor in determining the course of management of a UPJO. During the past 5 years, a growing number of urologists in both academic and nonacademic practices have been performing laparoscopic pyeloplasty for the management of UPJO in adults. Several factors, especially the surgeon's training, have an impact on the choice of procedure. Open pyeloplasty is still performed by a significant number of urologists. These data may be useful in designing physician education programs and/or future investigations to help define standard treatment practices for UPJO.

Pivot/Remote: a distributed database for remote data entry in multi-center clinical trials.
1. INTRODUCTION. Data collection is a critical component of multi-center clinical trials. Clinical trials conducted in intensive care units (ICU) are even more difficult because the acute nature of illnesses in ICU settings requires that masses of data be collected in a short time. More than a thousand data points are routinely collected for each study patient. The majority of clinical trials are still "paper-based," even if a remote data entry (RDE) system is utilized. The typical RDE system consists of a computer housed in the CC office and connected by modem to a centralized data coordinating center (DCC). Study data must first be recorded on a paper case report form (CRF), transcribed into the RDE system, and transmitted to the DCC. This approach requires additional monitoring since both the paper CRF and study database must be verified. The paper-based RDE system cannot take full advantage of automatic data checking routines. Much of the effort (and expense) of a clinical trial is ensuring that study data matches the original patient data. 2. METHODS. We have developed an RDE system, Pivot/Remote, that eliminates the need for paper-based CRFs. It creates an innovative, distributed database. The database resides partially at the study clinical centers (CC) and at the DCC. Pivot/Remote is descended from technology introduced with Pivot [1]. Study data is collected at the bedside with laptop computers. A graphical user interface (GUI) allows the display of electronic CRFs that closely mimic the normal paper-based forms. Data entry time is the same as for paper CRFs. Pull-down menus, displaying the possible responses, simplify the process of entering data. Edit checks are performed on most data items. For example, entered dates must conform to some temporal logic imposed by the study. Data must conform to some acceptable range of values. Calculations, such as computing the subject's age or the APACHE II score, are automatically made as the data is entered. Data that is collected serially (BP, HR, etc.) can be displayed graphically in a trend form along with other related variables. An audit trail is created that automatically tracks all changes to the original data, making it possible to reconstruct the CRF to any point in time. On-line help provides information on the study protocol as well as assistance with the use of the system. Electronic security makes it possible to lock certain parts of the CRF once it has been monitored. Completed CRFs are transmitted to the DCC via electronic mail where it is reviewed and merged into the study database. Questions about subject data are transmitted back to the CC via electronic mail. This approach to maintaining the study database is unique in that the study data files are distributed among the CC and DCC. Until a subject's CRF is monitored (verified against the original patient data residing in the hospital record), it logically resides at the CC where it was collected. Copies are transmitted to the DCC and are only read there. Any pre-monitoring changes must be made to the data at the CC. Once the subject's CRF is monitored, it logically moves to the DCC, and any subsequent changes are made at the DCC with copies of the CRF flowing back to the CC. 3. DISCUSSION. Pivot/Remote eliminates the need for paper forms by utilizing portable computers that can be used at the patient bedside. A GUI makes it possible to quickly enter data. Because the user gets instant feedback on possible error conditions, time is saved because the original data is close at hand. The ability to display trended data or variables in the context of other data allows detection of erroneous conditions beyond simple range checks. The logical construction of the database minimizes the problem of managing dual databases (at the CC and DCC) and keeps CC personnel in the loop until all changes are made.

Simple and low-cost tele-nuclear medicine conference system with the e-mail protocol.
PURPOSE: Because of the recent innovative growth in computer technology, digital imaging, and the Internet, we can take advantage of these facilities for education and clinical work in nuclear medicine. We developed a tele-nuclear medicine conference system with electronic mail (e-mail) on the Internet. METHODS: Twenty-one physicians (20 radiologists, 1 neurologist), 6 technologists and 2 medical students in six university hospitals (Japan 5, Canada 1), 5 local hospitals in Japan participated in this project. We used digital still cameras (330 k pixels) equipped with a floppy disk drive and 10 x optical zoom to digitize images with JPEG compression (640 x 480 matrix). The images were attached to e-mail messages (containing a brief description of each case). The mail was sent simultaneously to all members on the mailing list. Scintigram and SPECT images as well as other radiological images were sent by e-mail. Reply mails about each case were sent to all members via the mailing list. RESULTS: During a period of 6 months, 18 cases (tumor/infection: 7, bone: 6, cardiovascular: 1, neurology; 3, endocrine: 1) with 144 e-mails (average 5.6/case) were submitted to the conference. The average period of discussion was 15.6 days. The number of attached images was 1 to 9 (average, 4.2/e-mails). JPEG compression rate was 1/10 to 1/20. The quality of the images was good enough for discussion. Some cases required additional images for further discussion. CONCLUSION: Our tele-nuclear medicine conference with an electronic mailing list and digital camera was simple and low-cost. The conference system was useful for education and clinical work.

Facilitating faculty communications using an electronic bulletin board to store and organize listserv messages.
The Center for Academic Informatics of the Medical College of Pennsylvania and Hahnemann University uses BULLETIN, a public-domain bulletin board system for VMS, to facilitate communication between our faculty and staff and their colleagues at other institutions. In conjunction with the VAX electronic mail program, BULLETIN can store and organize messages from Internet listserv mailing lists. The software allows us to set up individual folders within BULLETIN for each list of interest to our users. This means that they do not have to sift through "lists of lists" in order to find the ones that coincide with their interests. Another significant advantage is that users' electronic mailboxes do not become cluttered with postings from a variety of lists, interfering with their ability to read and respond to their "real" electronic mail. Yet they can still post to lists, and the posting will be sent from their user name and electronic address. BULLETIN also offers a natural structure for setting up interest groups where local users can post announcements, questions, and answers.

Compliance wearing a heel lift during 8 weeks of military training in cadets with limb length inequality.
STUDY DESIGN: Retrospective descriptive study. OBJECTIVES: To examine compliance in wearing heel lifts during 8 weeks of military training in cadets identified with limb length inequalities. BACKGROUND: Lack of compliance can be blamed for countless poor outcomes in the medical community. Reported compliance with intervention protocols has been reported to range from 11% to 95%. All 1100 new cadets in the class of 2005 were screened for a limb length inequality One hundred ninety-eight out of 1100 cadets were identified to have a limb length inequality on physical exam and volunteered to participate. Cadets were randomly assigned to a heel lift or control group. Cadets in the heel lift group were instructed to wear a heel lift at all times throughout cadet basic training to attempt to prevent overuse injuries. There was no difference (P > .05) between the heel lift group or the control group on injury rate or excusal days. METHODS AND MEASURES: In an attempt to discern whether the preventive intervention was ineffective by design or if noncompliance was to blame, investigators asked cadets via electronic mail survey to report compliance with heel lift wear as a percentage (0%-100%). RESULTS: Seventy-six out of 99 (76.8%) cadets in the heel lift group responded to the electronic mail survey. Mean reported compliance was 38%. Eighteen cadets reported between 70% and 100% compliance. The remaining 58 cadets reported less than 70% compliance. CONCLUSIONS: Cadet compliance was poor with the use of a heel lift. Physical therapists throughout the military often prescribe heel lifts, therapeutic exercises, or medication and assume good to excellent compliance. This study reminds providers that good compliance should not be assumed in any setting.

The grapefruit diet.
According to major research studies, 50 percent of all distributed data processing is really distributed document delivery. Up to 70 percent of all telephone calls do not reach the intended party, resulting in what has been aptly called, "telephone tag." Electronic mail is a rapidly emerging technology using computers and telecommunications networks to transmit notes, messages and documents instantaneously. Online information systems for document management, distribution and retrieval is an area of electronic mail far more powerful. Computer teleconferencing, as it is often called, allows for ongoing meetings online with persons from remote locations without regard to time zone limitations. This article will focus on the definitions of computer teleconferencing and other new "online" technologies, and how they will impact document development, management and distribution. It is based on the author's presentation at the 1983 NMA Annual Conference & Exposition in Philadelphia.

Establishing an international computer network for research and teaching in public health and epidemiology.
Most universities and major research institutions in North America, Western Europe and around the Pacific are connected via computer communication networks. The authors have used these networks' accessible, low cost, electronic mail system to develop a network of public health researchers and teachers. Current and potential uses of this network are discussed. These networks can not only facilitate international cooperation within public health; they also make it possible to conduct international collaborative research projects that would be too cumbersome and time consuming to initialize and conduct without this communication facility. One participant from Hungary has been able to participate in the network by using telefax. This has some drawbacks compared to electronic mail. In this era of rapid change in Eastern Europe, we urge that electronic communication be made freely available to colleagues in Eastern Europe.
