An international summer school on health informatics: a collaborative effort of the Amsterdam Medical Informatics Program and IPhiE--the International Partnership for Health Informatics Education.

PURPOSE: Today, the need for health informatics training for health care professionals is acknowledged and educational opportunities for these professionals are increasing. To contribute to these efforts, a new initiative was undertaken by the Medical Informatics Program of the University of Amsterdam-Academic Medical Center and IPHIE (IPhiE)-the International Partnership for Health Informatics Education. In the year 2004, a summer school on health informatics was organized for advanced medical students from all over the world. METHODS: We elaborate on the goals and the program for this summer school. In developing the course, we followed the international guidelines of the International Medical Informatics Association-IMIA. Students provided feedback for the course through both summative and formative evaluations. As a result of these evaluations, we outline the lessons we have learned and what consequences these results have had in revising the course. RESULTS: Overall the results of both the summative and formative evaluation of the summer school showed that we succeeded in the goals we set at the beginning of the course. Students highly appreciated the course content and indicated that the course fulfilled their educational needs. The decision support and image processing computer practicums however proved too high level. We therefore will redesign these practicums to competence requirements of medical doctors as defined by IMIA. All participants recommended the summer school event to other students. CONCLUSIONS: Our experiences demonstrated a true need for health informatics education among medical students and that even a 2 weeks course can fulfill health informatics educational needs of these future physicians. Further establishment of health informatics courses for other health professions is recommended.

Impact of CPOE on mortality rates--contradictory findings, important messages.

OBJECTIVE: To analyze the seemingly contradictory results of the Han study (Pediatrics 2005) and the Del Beccaro study (Pediatrics 2006), both analyzing the effect of CPOE systems on mortality rates in pediatric intensive care settings. METHODS: Seven CPOE system experts from the United States and Europe comment on these papers. RESULTS: The two studies are not contradictory, but almost non-comparable due to differences in design and implementation. They demonstrate the range of outcomes that can be obtained from introducing informatics applications in complex health care settings. Implementing informatics applications is a sociotechnical activity, which often depends more on the organizational context than on a specific technology. As health informaticians, we must not only learn from failures, but also avoid both uncritical scepticism that may arise from drawing overly general conclusions from one negative trial, as much as uncritical optimism from limited successful ones. CONCLUSION: The commentaries emphasize the need to promote systematic studies for assessing the socio-technical factors that influence the introduction of increasingly sophisticated informatics applications within complex organizations. The emergence of evidence-based health informatics will be based both on evaluation guidelines and implementation guidelines, both of which increase the chances of successful implementation. In addition, well-educated health informaticians are needed to manage and guide the implementation processes.

The International Partnership for Health Informatics Education: lessons learned from six years of experience.

OBJECTIVES: To inform the medical and health informatics community on the rational, goals, and the achievements of the International Partnership for Health Informatics Education--IPHIE, (I phi E), that was established at six universities in 1999. METHODS: We elaborate on the overall goals of I phi E and describe the current state of affairs: the activities undertaken and faculty and student experience related to these activities. In addition we outline the lessons we have learned over these past six years and our plans for the future. RESULTS: I phi E members first started to collaborate by supporting and encouraging the exchange of talented students and faculty and by establishing joint master classes for honors students. Following the success of these activities, new initiatives were undertaken such as the organization of student workshops at medical informatics conferences and a joint course on strategic information management in hospitals in Europe. CONCLUSIONS: International partnerships such as I phi E take time to establish, and, if they are to be successful, maintaining leadership continuity is critically important. We are convinced that I phi E promotes professionalism of future medical informatics specialists. There will be a continuing growth of globalization in higher education. It will therefore become increasingly important to offer educational programs with international components.

The International Partnership in Health Informatics Education.

The International Partnership for Health Informatics Education (IPHIE) seeks to promote education through international collaboration of graduate and undergraduate training programs in Medical and Health Informatics. In 1998 an International Partnership of Health Informatics Education was established at six universities: The University of Amsterdam, the Universities of Heidelberg and Heilbronn, the University of Health Informatics and Technology Tyrol at Innsbruck, the University of Minnesota and the University of Utah. The overall goal of this cooperation was to form a network for training and educating medical informatics faculty and students in order to prepare them for leading international positions in medical information and communication technology. In this paper we describe the current state of affairs of IPhiE: the activities undertaken, our experiences, the lessons we have learned over these past five years. In addition we outline our plans for the future.

In vivo regulation of syndecan-3 expression in the rat uterus by 17 beta-estradiol.

The immature rat uterus has been extensively used as an in vivo model system to study the molecular mechanisms of steroid hormone actions. In this study, we demonstrated the regulated expression of syndecan-3 in the rat uterus by the steroid hormone 17 beta-estradiol. Administration of a single physiological dose of 17 beta-estradiol (40 microg/kg) to ovariectomized immature animals induced a rapid and transient increase in uterine syndecan-3 mRNA. Transcript levels reached a peak elevation of 3-fold above saline control tissues 4 h after hormone administration. Inhibition of message up-regulation by actinomycin D but not cycloheximide indicated a hormone response dependent on RNA transcription but not new protein synthesis. The estrogenic ligands estriol and tamoxifen were also effective at raising syndecan-3 mRNA levels; however, nonestrogenic ligands, including progesterone, 5 alpha-dihydrotestosterone, and dexamethasone, failed to stimulate a change in mRNA levels. Hormone-induced changes in mRNA led to transient changes in syndecan-3 protein content and significant alteration in the temporal and spatial expression in endometrial epithelial cells. Collectively, these data show that the steroid hormone 17 beta-estradiol, regulates transcription of the syndecan-3 gene in the uterus via an estrogen receptor-dependent mechanism. This estrogen-regulated expression of syndecan-3 may play an important role in changes in tissue ultrastructure crucial for proper uterine growth.

Predictors of eating disorder scores in children ages 6 through 14: a longitudinal study.

The objective of this study was to identify variables that predict higher eating disorder scores in non-clinical boys and girls ages 6 through 14. Two hundred sixteen children participated and were tested annually for 3 years. A TV-video procedure was used to measure the accuracy of body size judgments. Variables examined included demographic, familial, sociocultural, social, esteem, and clinical variables. Predictors of higher eating disorder scores for both sexes included height and weight, children's perceptions of parental concerns about their body size, low body esteem, and depression. For girls only, a larger perceived body size and smaller idealized body size were also predictors. Teasing was a predictor for boys only. An analysis of longitudinal changes suggests that low body esteem becomes a significant factor around age 9, depression emerges as a predictor at age 10, and body size judgments in perceived and ideal sizes at ages 11 and 12. Changes over 2 years in individuals' weight and height, teasing, body dissatisfaction, and eating disorder scores were also found to predict higher eating disorder scores.

IPHIE: an International Partnership in Health Informatics Education.

Medical informatics contributes significantly to high quality and efficient health care and medical research. The need for well educated professionals in the field of medical informatics therefore is now worldwide recognized. Students of medicine, computer science/informatics are educated in the field of medical informatics and dedicated curricula on medical informatics have emerged. To advance and further develop the beneficial role of medical informatics in the medical field, an international orientation of health and medical informatics students seems an indispensable part of their training. An international orientation and education of medical informatics students may help to accelerate the dissemination of acquired knowledge and skills in the field and the promotion of medical informatics research results on a more global level. Some years ago, the departments of medical informatics of the university of Heidelberg/university of applied sciences Heilbronn and the university of Amsterdam decided to co-operate in the field of medical informatics. Now, this co-operation has grown out to an International Partnership of Health Informatics Education (IPHIE) of 5 universities, i.e. the university of Heidelberg, the university of Heilbronn, the university of Minnesota, the university of Utah and the university of Amsterdam. This paper presents the rationale behind this international partnership, the state of the art of the co-operation and our future plans for expanding this international co-operation.

The HELP hospital information system: update 1998.

The HELP hospital information system has been operational at LDS Hospital since 1967. The system initially supported a heart catheterization laboratory and a post open heart Intensive Care Unit. Since the initial installation the system has been expanded to become an integrated hospital information system providing services with sophisticated clinical decision-support capabilities to a wide variety of clinical areas such as laboratory, nurse charting, radiology, pharmacy, etc. The HELP system is currently operational in multiple hospitals of LDS Hospital's parent health care enterprise--Intermountain Health Care (IHC). The HELP system has also been integrated into the daily operations of several other hospitals in addition to those at IHC. Evaluations of the system have shown: (1) it to be widely accepted by clinical staff; (2) computerized clinical decision-support is feasible; (3) the system provides improvements in patient care; and (4) the system has aided in providing more cost-effective patient care. Plans for making the transition from the 'function rich' HELP system to more modern hardware and software platforms are also discussed.

Body-size estimations in children six through fourteen: a longitudinal study.

Estimates of perceived and ideal body size were collected in 216 boys and girls ages 6 through 14 years. Video methodology was used to adjust the width of a life-size frontal image of the children. Longitudinal data were collected annually for three years, beginning at ages 6, 9, and 12. Three psychological methods were used, including the method of adjustment, staircase method, and adaptive probit estimation technique which permitted separate measures of the children's point of subjective equality and just noticeable difference values. The point of subjective equality is the body size which is subjectively equal to the child's perception of self. The just noticeable difference is the amount of change in body size necessary to detect the difference 50% of the time. Acceptable size boundaries were also measured, using the method of adjustment. Over-all, children were accurate in estimating their body width, with average overestimation of less than 2%. Overestimation decreased within each age group during the three years of the study. There were no differences between ages or sexes. Both point of subjective equality and just noticeable difference values decreased significantly during the three years of the study. The latter values significantly decreased as children became older. Body dissatisfaction (the discrepancy between perceived and ideal size) remained low for boys in all age groups. Girls' body dissatisfaction significantly increased across ages, beginning at age 9. Test-retest consistency of both perceived and ideal size judgments at intervals of one and two years were low. Acceptable boundaries in body width were similar between sexes and across age cohorts.

Development and validation of two new scales for assessment of body-image.

This study reports the development and validation of two new and improved tools for assessment of body-image. Two schematic contour scales were created using a frontal view photograph of an adult male and female with height and weight of the median American. A 2-figure analogue scale was created by distorting this drawing by +/- 30%. A 13-card scale was created by generating 13 drawings distorted between +/- 30% by increments of 5%. Evidence is presented for the reliability and validity of both scales. The advantages of these new scales over existing figural and silhouette scales are discussed.

Methodological concerns when using silhouettes to measure body image.

This paper discusses methodological concerns of using silhouette figures to measure body images. These include concerns related to scale coarseness (limiting response options to one of a finite number of drawings), restriction of range, method of presentation, and scale of measurement. Recommendations are made to address these limitations, and an alternative silhouette scale using continuous scale measurements is proposed.

Summary recommendations for responsible monitoring and regulation of clinical software systems. American Medical Informatics Association, The Computer-based Patient Record Institute, The Medical Library Association, The Association of Academic Health Science Libraries, The American Health Information Management Association, and The American Nurses Association.

Clinical software systems are becoming ubiquitous. A growing literature documents how these systems can improve health care delivery, but concerns about patient safety must now be formally addressed. In 1996, the U.S. Food and Drug Administration (FDA) called for discussions on regulation of software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. These recommendations were revised and approved by the American Medical informatics Association Public Policy Committee and Board. Other organizations reviewed, modified, and approved the recommendations, and the Boards of Directors of most of the organizations in the consortium endorsed the guidelines. The consortium proposes four categories of clinical system risk and four classes of monitoring and regulatory action that can be applied on the basis of the risk level. The consortium recommends that most clinical software systems be supervised locally and that developers of health care information systems adopt a code of good business practices. Budgetary and other constraints limit the type and number of systems that the FDA can regulate effectively; therefore, the FDA should exempt most clinical software systems and focus on systems that pose high clinical risk and provide limited opportunity for competent human intervention.

Perspectives on development of IEEE 1073: the Medical Information Bus (MIB) standard.

Automated data capture from bedside patient medical devices is now possible using a new Institute of Electrical and Electronic Engineering (IEEE) and American National Standards Institute (ANSI) Medical Information Bus (MIB) data communications standard (IEEE 1073). The first two standard documents, IEEE 1073.3.1 (Transportation Profile) and IEEE 1073.4.1 (Physical Layer), define the hardware protocol for bedside device communications. With the above noted IEEE MIB standards in place, hospitals can now start designing customized applications for acquiring data from bedside devices such as bedside monitors, i.v. pumps, ventilators, etc. for multiple purposes. The hardware 'plug and play' features of the MIB will enable nurses and physicians to establish communications with these devices simply and conveniently by plugging them into a bedside data connector. No other action will be necessary to establish identification of the device or communications with the device. Presently to connect bedside devices, technical help from hardware and software experts are required to establish such communications links. As a result of standardization of communications, it will be easy to establish a highly mobile network of bedside devices and more promptly and efficiently collect patient related data. Collection of data automatically should lead to the design of new medical computing applications that will tie in directly with the emerging mission and operations of hospitals. The MIB will permit acquisition of patient data more efficiently with greater accuracy, more completeness and more promptly. The above noted features are all essential to the development of computerized treatment protocols and should lead to improved quality of patient care. This manuscript provides the rational and historical overview of the development of the MIB standard.

Medical Information Bus usage for automated IV pump data acquisition: evaluation of usage patterns.

OBJECTIVE: To identify factors which influence the choice of nurses to use automated collection of i.v. pump data from a prototype Medical Information Bus. DESIGN: Observational study for a duration of three and one-half months. SETTING: Four intensive care units, each with different missions, in an adult hospital. SUBJECTS: One hundred fifty-eight registered nurses including both full and part time. MEASUREMENTS AND MAIN RESULTS: Data were collected from the hospital information system about infusion orders including the type of medication, the number of rate changes, the method of documenting rate changes and the infusion methods. The method of documentation for infusion rate changes was defined as either automated, using a prototype Medical Information Bus (MIB), or manual, using the keyboard at a bedside computer terminal. The method of infusion was defined as either straight gravity feed without an i.v. pump ('no pump'), infusion using a pump but without connection to the hospital information system ('pump only') and infusion using a pump which was connected to the hospital information system using a prototype Medical Information Bus ('automated'). A total of 22,199 rate changes were documented during the study period and of those, 22,055 (99.35%) used the 'automated' method. Medications with the highest average rate change per single container were; Nitroprusside Sodium (9.50), Epinephrine (9.08) and Epoprostenol (7.50). CONCLUSIONS: The nurses used automated i.v. pump data acquisition with medications which required frequent rate changes.
