Three Province Study
Dr. George Kephart is Co-Investigator in a two year study of the effects of health care reform upon health care service utilization in Manitoba, Alberta and Nova Scotia. The study is a partnership between Dalhousie, the University of Alberta and the Manitoba Centre for Health Policy and Evaluation at the University of Manitoba. All three provinces have experienced resource reductions within their health care systems but the nature of changes which were implemented vary among the provinces. The study will utilize PHRU databases and similar databases in Alberta and Manitoba to study the effects of the different models of reform upon the utilization of health services. The project is funded by the Medical Research Council and the National Health Research Development Program.
Measuring Adherence to Hypertension Practice Guidelines
Drs. Kephart, Putnam, Burge, Sketris, Whelan and Flowerdew have received MRC funding for a two year study of adherence to evidence-based practice Guidelines for hypertension medications. The study will utilize PHRU databases and data from the Nova Scotia Health Survey to develop and validate methods for identifying prevalent and incident cases of hypertension and prevalent cases of selected co-morbid conditions. Trends in prescribing patterns will be identified and the impact of published clinical practice guidelines will be assessed.
MRC Studentship
Donna Comeau has received a CEM/CDMA/MRC Studentship to support her work with PHRU on the use of administrative databases to study prescribing for hypertension.
Compliance with Insulin and Hypoglycemics in the Over-65 Population
Drs. Sketris and Kephart have received funding through Dr. David Sclar, Collage of Pharmacy, Washington State University, to act as Co-Investigators with Dr. Sclar in a study of the compliance of Nova Scotians aged 65 and over to insulin and hypoglycemics. The project will utilize PHRU databases to develop and validate compliance indicators.
Diabetes Care Program
Dr. John LeBlanc has received funding from the Laboratory Centre For Disease Control to utilize the Nova Scotia Heart Health Survey, Diabetes Care Program Registry and PHRU databases to develop and test estimates of the incidence and prevalence of diabetes mellitus at the county, regional and provincial level in Nova Scotia.
Multiple Sclerosis Societal Cost study
Drs. Murray Brown and Jock Murray along with Dr. Luanne Metz of the University of Calgary will be participating in a joint study of the societal costs of MS. The initial phase of the study involves primary data collection related to health status measures and private/public sector direct/indirect costs. Linkage to Alberta and Nova Scotia administrative databases is planned, if the final budget permits.
Nova Scotia Drug Atlas
Drs. Kephart and Sketris have received funding from the Department of Health to develop a geographical profile of prescription and OTC drug use by Nova Scotians, based on the Nova Scotia Health Survey.
Inter-County Variation in Pharmacare Expenditures

Dr. Kim Blake and Dr. Patty Wren have implemented data collection of pediatric undergraduate clerkship experiences from the ER. The feedback information will be assembled into a database format to elicit trends in student performance and to provide direction for improvement in the undergraduate pediatric rotation experience. Approximately 3 months of data have been collected thus far. Database design, data entry and analysis may be offered to a medical student as a summer project. Dr. Wren is hoping to expand the effort to include analysis of post graduate ER experiences.
Videoconferencing Feedback Analysis
Dr. Blake has collected feedback from tutors using the videoconferencing system for pediatric case tutorials. Data has been analysed from a six month period. A research grant is tentatively planned to continue funding of this project.
Simulated Adolescent-Student Encounters Analysis
This research project of Dr. Kim Blake's will analyse the feedback from simulators portraying patients and parents on their encounters (history taking and physical examination) with medical students. This study will determine if feedback from the simulators can positively affect medical students' abilities to interview and examine an adolescent patient. Funding is from a 1998 grant from the Division of Medical Education.
Pediatric Community Experience Analysis
In the near future, as part of the undergraduate experience in pediatrics, students will have the opportunity to follow patients that they have seen in the hospital setting to the community. The students will see first hand the lifestyle changes that can come about after a hospital stay and with alterations in health care requirements. Feedback from students, parents, and students involved in the program will be analysed to determine the usefulness of this line of education and insight into "the patient at home" and used as a research model. It is hoped that there will be interfaculty collaboration for this project headed by Dr. Blake and Dr. Yhap.

Computer-Aided Guiding System For Arrythmia Ablation

INTRODUCTION: Various approaches have been used to investigate the electrical activation sequence in the heart; they include invasive methods that require recording multiple electrograms on the inner or outer surface of the heart, and noninvasive methods based on recording multiple electrocardiograms (ECGs) on the body surface. Collectively, these approaches are referred to as cardiac mapping. One of the important applications of cardiac mapping is to investigate the activation sequence in patients at risk of life-threatening arrhythmias. The accurate localization of arrhythmogenic regions is essential for understanding the mechanisms that underlie the arrhythmia, for evaluating the effect of drugs, and for guiding surgical or catheter ablation procedures. With current computer technology, one can perform noninvasive body-surface potential mapping (BSPM) by acquiring simultaneously an entire set of ECGs at many locations on the thorax (using from 32 to 240 leads). Invasive acquisition of cardiac electrograms can also be performed simultaneously from many sites, using endocardial ``basket catheters'' that are introduced percutaneously into the heart chambers. One major drawback of the currently used methods of catheter-based endocardial mapping is that they cannot relate the individual intracardiac electrograms to the entire activation sequence in the heart. Our proposed method---combining endocardial mapping and three-dimensional computer modelling of the heart's activation sequence---addresses this drawback.

PROPOSAL: We propose a new method and system for remotely (via network) guiding ablation therapy in patients at risk of life-threatening cardiac arrhythmias. Our method requires that the arrhythmogenic substrate in the heart be first explored by the catheter-based mapping that yields direct measurements of electrograms at multiple endocardial sites together with their topographic data; this information is to be used in constructing 3D electroanatomical maps of the heart's chambers. The kernel of our method---and its unique feature---consists of computer simulations of atrial/ventricular activation sequences in a realistic anisotropic model of the human heart, under conditions that simulate the anatomical and electrophysiological substrate, as documented by electroanatomical mapping, underlying each individual patient's arrhythmia. To implement this method for guiding the ablation therapy of life-threatening ventricular arrhythmias and to test the feasibility of guiding the ablation via network, we propose to perform a pilot study at Toronto General Hospital, QEII hospital in Halifax and at Hopital Sacre Coeur in Montreal; all these medical centers will be networked with the remote powerful computing facilities at Dalhousie University, which will perform data processing and heart-model simulations. Thus, in summary, we propose to develop new guiding procedures for ablating lethal cardiac arrhythmias by combining existing techniques of endocardial electroanatomical mapping and body-surface potential mapping with a computer model of the cardiac electrical activation process, which would be available as a remote ``consultant'' to the participating medical centers. Although a large part of our proposed work will consist of software development (heart model, very-fast processing of measured electrograms), the most important component of this study will be to test the feasibility of ``remote consultation'' requiring massive amounts of data to be transfered via network at high speed.

Dr. Cupido Daniels, Head of the Diagnostic Medical Physics Division and Associate Professor of Radiology is the visionary and the technician behind the development of a series of Radiology teaching CD-ROMs. The CD tutorials use text and x-rays to teach about imaging modalities, detectable anatomy and pathology and related cases are presented. Since developing the first CD, Fundamentals of Diagnostic Radiology, Daniels has collaborated with radiologists at the University of Montreal and the University of Toronto to produce Fundamentals of Breast Imaging, Imaging of Low Back Pain, and Trauma in the Adult Head. A new addition has been Fundamentals of Pediatric Radiology.

International interest in these CD-ROMS has been large enough to have some of the CDs translated into German and Spanish and plans are under way to make them available in French, Polish, Russian, Italian, and others. The CDs have also been popular in the marketplace. U.S.-based Medical Physics Publishing and the Medical Technology Management Institute have been mass producing, marketing, and selling these products worldwide. Fundamentals of Breast Imaging received a Cum Laude award at the Radiological Society of North America 1996 annual meeting.

The goal now is to secure more private sector support and to encourage more interdepartmental collaboration projects.

Medical Records System
Dr. J.B. Gajewski has taken the Carefiler Medical Records System and customized it for urology patients and now has nearly ten thousand electronic patient files. This includes information on the results of tests and procedures, medications, and patient progress. It also allows easy collection of summary data for analysis for research and statistics. The form letter feature makes procedure and clinic notes a breeze, virtually eliminating dictating and its sometimes long turnaround time. PATIENT MANAGEMENT
"Prostate Crystal Ball"
This Windows-based computer program, created by David Bell, Jerzy Gajewski, Jedrzej Gajewski, and Riki Sahajpal, aids in making treatment decisions for patients with prostate cancer. Using survival data from the Framingham Study and Statistics Canada, as well as published progression rates of prostate cancer, this program estimates the patient's life expectancy with and without prostate cancer helping urologists determine if radical therapy or conservative measures would be more appropriate. PHYSICIAN DECISION SUPPORT
Image Enhancement
Jerzy Gajewski, Richard Norman, Kesava Rajagopalan and Peter Gregson collaborated on a geometric filtering system for enhancement of prostate transrectal ultrasound images. This image processing significantly improves the contrast in the detection of hypoechoic lesions. INTERFACE TECHNOLOGY

¶W.K.K. KELLOG HEALTH SCIENCES LIBRARY

Kellogg Library Website: http://www.library.dal.ca/kellogg
Interwoven with the Dalhousie University Libraries homepage this site provides information about the Library's policies and services, announcements and notices, as well as links and instructions for access to the databases which have remote and campus-wide access capabilities, and links to other related internet websites. COMMUNICATION
Database Access
Many bibliographic databases are currently accessible from outside the Library. Medline, Cinahl, HealthStar, Bioethicsline, and International Pharmaceutical Abstracts are all usable from home or off-campus office via the internet through the Library's web page. Also available, but only to those users hardwired to the Dal ethernet, including some locations in the QE II and IWK Grace, are Health Indicators, and PsycLit.

Access to the Cochrane Library and to ABI Inform Full-Text allow users to browse full text articles. The Library's website also provides access to a growing number of full-text biomedical journals. It is hoped that in the future there will be an increase in the range of full text journals available in the electronic format.
Available now to any Dal student or faculty member are Swetscan and UnCover which are two databases which permit users to search the table of contents of particular journals. Both are linked to document delivery services via the internet. One can now self-order document requests for delivery to the Kellogg Library
There is also remote access to Novanet, the catalogue of books, journals and AV materials in all Halifax/Dartmouth university libraries as well as those at St. FX and UCCB.
Training programs are provided on the use of all the above databases and on internet resources. COMMUNICATION
Document Delivery Service
Automated routing allows document requests to be immediately sent to a North American medical library that can fill the request. With document scanning and delivery via the internet documents can usually be delivered within three working days. COMMUNICATION
