Current Research Programs - Health InformaticsMOCHA - GP Cardiovascular Risk Assessment Software Tool MOCHA - GP Cardiovascular Risk Assessment Software ToolThe MOCHA (Modifying Clinical Heart Activities) project is funded by Alphapharm Pty Ltd and is being developed by the Department of General Practice, the University of Adelaide. Funding commenced in October 2003 and the project is due for completion in June 2005. Project deliverables are as follows:
Description and aim of MOCHAMOCHA is an integrated information-communication technology program that aims to enhance existing clinical software systems to improve disease management of cardiovascular risk. Cardiovascular disease remains a major cause of disease burden in developing and developed regions and disease management has increasingly been discussed as a means of curtailing health care costs and improving patient outcomes. The conceptual basis for the program is one of ‘patient-centered’ care which is about sharing management between patient and doctor and includes the key principles of communication with patients; partnerships and a focus beyond specific conditions, on health promotion and healthy lifestyles. Key features include goal setting, written management plans and regular follow-up.There is evidence that such an approach improves management for cardiovascular disease. Additional studies that focus on the use of computer based clinical decision support systems (eg. standalone risk calculators), have demonstrated that a combined approach to integrate both risk estimation and management recommendations may be required to be of benefit to patients and patient outcomes. Stand-alone cardiovascular risk estimation in primary care utilising computer based clinical decision support systems, is no more likely to reduce the cardiovascular risk in patients than patients receiving usual care. Software developmentInitial software development focused on utilising the Framingham coronary heart disease risk function derived from observational studies of the original Framingham cohort. Functionality during this phase of the software development concentrated particularly in emulating the functionality of disseminated Framingham algorithms, which generate the absolute risk of having a cardiovascular event for individual patients – demonstrated to Alphapharm Pty Ltd as an online HTML risk calculator. In assessing the functionality of the risk calculator for MOCHA, the development team made comparisons against other computerised risk calculators and the de-facto standard utilised in the Australian primary care environment i.e. the National Prescribing Service (NPS) paper-based New Zealand Cardiovascular Risk Calculator. Further development concentrated on re-orientating cardiovascular risk calculator within a broader framework for the management of hypertension and cardiovascular risk management. Australian hypertension management guidelines have recently been updated (Hypertension Management Guide for Doctors; National Heart Foundation, 2004) and these were used as the basis for developing a systematic computerised approach to the management of hypertension. In particular, a toolkit was developed which can be used in a clinical consultation directly with patients; the interface can guide a patient and general practitioner through management of hypertension, the reasons for undertaking such a management pathway and the role of risk factors that modulate management. Hyperlinks within the screens, provide an additional educational mechanism that allows patient access to additional information or as a prompt for general practitioners. A paper and presentation has been presented at the International Conference on Qualitative Research in IT & IT in Qualitative Research in late 2004 by Dr Anne Wilson and Andre Duszynski.

General Practice (GP) Vocabulary ProjectIntroduction and BackgroundIn 1999 the General Practice Computing Group (GPCG) established a "Coding Jury". It had wide representation. The task of the Coding Jury was to select a single coding system that would be suitable for use in computerised general practice clinical systems. The Jury limited its scope to symptoms, findings, problems, reasons and diagnoses. In August 2000, the "Final Report of the General Practice Coding Jury" was published. The GP Coding Jury recommended that ICD-10-AM, with the addition of specific
and essential general practice terms, be adopted as the coding system to
be used in general practice in Australia for the next five years. The long-term
recommendation was that Australia should become involved in the development
of SNOMED®CT. The Jury also emphasized the need to "flag" the
terms used by general practitioners, thereby facilitating the presentation
of more relevant "pick-lists". The report commented that intervention,
pathology, radiology and medication terminologies were also important for
General Practice - the "GP Vocabulary Project" resulted. The Project OverviewThe "GP Vocabulary Project" is an initiative of the General Practice Computing Group (GPCG) and has been funded by the Commonwealth Department of Health and Ageing (DoHA). It is designed to assist the building and support of a standard general practice terminology that is suitable for the management of information obtained during healthcare encounters - i.e. an "interface terminology". It has three stages:
Stage One of the GP Terminology Project commenced in June 2002. The Purpose of Stage One of the ProjectThe purpose of stage one of the GP Vocabulary Project was to:

A committee of HL7 is working on the analysis and unification of the many dose-forms described for drug usage.
At the September 2004 HL7 workshop the task of providing a tool that would assist the work of uniquely defining each dose-form by its relationships was given to Don Walker (Australia). Bill Hess (USA) was repsonsible for collecting and collating a comprehensive list of dose-forms. Julie James (UK) allocated defining-features to each dose-form. The paper Principles for Modelling the Dose Form Vocabulary elaborates on this.
By December 2004, the Poly-browser and Authoring Tool (PAT) contained all the dose-forms (as a “terminology”) extracted from Bill’s original compilation by Julie. Bill’s data was included in the PAT and linked to appropriate dose-form concepts.
The PAT contains tools that help in the creation of defining-concept-relationships. These are described in the PAT Concept Definitions Tools document.
The work needed to uniquely identify concepts by their relationships has yet to be done.
The following are the above referred documents and a stand alone, single user, zipped version of the PAT containing drug-dose-forms and data provided by Julie James and Bill Hess.
