Selected AbstractsUnified Medical Language System Coverage of Emergency-medicine Chief ComplaintsACADEMIC EMERGENCY MEDICINE, Issue 12 2006Debbie A. Travers PhD Abstract Background Emergency department (ED) chief-complaint (CC) data increasingly are important for clinical-care and secondary uses such as syndromic surveillance. There is no widely used ED CC vocabulary, but experts have suggested evaluation of existing health-care vocabularies for ED CC. Objectives To evaluate the ED CC coverage in existing biomedical vocabularies from the Unified Medical Language System (UMLS). Methods The study sample included all CC entries for all visits to three EDs over one year. The authors used a special-purpose text processor to clean CC entries, which then were mapped to UMLS concepts. The UMLS match rates then were calculated and analyzed for matching concepts and nonmatching entries. Results A total of 203,509 ED visits was included. After cleaning with the text processor, 82% of the CCs matched a UMLS concept. The authors identified 5,617 unique UMLS concepts in the ED CC data, but many were used for only one or two visits. One thousand one hundred thirty-six CC concepts were used more than ten times and covered 99% of all the ED visits. The largest biomedical vocabulary in the UMLS is the Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT), which included concepts for 79% of all ED CC entries. However, some common CCs were not found in SNOMED CT. Conclusions The authors found that ED CC concepts are well covered by the UMLS and that the best source of vocabulary coverage is from SNOMED CT. There are some gaps in UMLS and SNOMED CT coverage of ED CCs. Future work on vocabulary control for ED CCs should build upon existing vocabularies. [source] Developing Clinical Terms for Health Visiting in the United KingdomINTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 2003June Clark BACKGROUND The UK health visiting service provides a universalist preventive health service that focuses mainly on families with young children and the elderly or vulnerable, but anyone who wishes can access the services. The principles of health visiting have been formally defined as the search for health needs, the stimulation of awareness of health needs, influencing policies that affect health, and the facilitation of health-enhancing activities. The project is currently in its fourth phase. In phase 1, 17 health visitors recorded their encounters with families with new babies over a period of 3 months; in phase 2, 27 health visitors recorded their encounters with a wider range of clients (769 encounters with 205 families) over a period of 9 months; in phase 3, the system is being used by a variety of healthcare professionals in a specialist program that provides intensive parenting support; phase 4 is developing a prototype of an automated version for point-of-contact recording. UK nursing has no tradition of standardized language and the concept of nursing diagnosis is almost unknown. Over the past decade, however, the government has initiated the development of a standardized terminology (Read codes) to cover all disciplines and all aspects of health care, and it is likely that the emerging SNOMED-CT terminology (a merger of the Read codes with the SNOMED terminology) will be mandated for use throughout the National Health Service (NHS). MAIN CONTENT POINTS The structure and key elements of the Omaha System were retained but the terminology was modified to take account of the particular field of practice and emerging UK needs. Modifications made were carefully tracked. The Problem Classification Scheme was modified as follows: ,All terms were anglicized. ,Some areas , notably relating to antepartum/postpartum, neonatal care, child protection, and growth and development,were expanded. ,The qualifiers "actual,""potential," and "health promotion" were changed to "problem,""risk," and "no problem." ,Risk factors were included as modifiers of "risk" alongside the "signs and symptoms" that qualify problems. The Intervention Classification was modified by substituting synonymous terms for "case management" and "surveillance" and dividing "health teaching, guidance, and counseling" into two categories. The Omaha System "targets" were renamed "focus" and a new axis of "recipient" was introduced in line with SNOMED-CT. The revised terminologies were tested in use and also sent for review to 3 nursing language experts and 12 practitioners, who were asked to review them for domain completeness, appropriate granularity, parsimony, synonymy, nonambiguity, nonredundancy, context independence, and compatibility with emerging multiaxial and combinatorial nomenclatures. Review comments were generally very favourable and modifications suggested are being incorporated. CONCLUSIONS The newly published government strategy for information management and technology in the NHS in Wales requires the rapid development of an electronic patient record, for which the two prerequisites are structured documentation and the use of standardized language. The terminology developed in this project will enable nursing concepts to be incorporated into the new systems. The experiences of the project team also offer many lessons that will be useful for developing the necessary educational infrastructure. [source] Will Systematized Nomenclature of Medicine-Clinical Terms improve our understanding of the disease burden posed by allergic disorders?CLINICAL & EXPERIMENTAL ALLERGY, Issue 11 2007C. R. Simpson Summary Analysis of data collected through the use of high-quality computerized systems is vital if we are to understand the health burden from allergic disease. Coding systems currently used, such as the World Health Organization's International Classification of Diseases and the Read system, have however been criticized as being unduly restrictive and hence inadequate for the detailed coding of allergic problems. Greater granularity of coding can be achieved by using the Systematized Nomenclature of Medicine-Clinical Terms (SNOMED-CT) system, which will be adopted by several countries including the United States and United Kingdom. Before the introduction of SNOMED-CT, it is important that several issues are resolved, including ensuring that adequate mapping occurs from existing systems, that the SNOMED-CT is trialled before general implementation, and that training is provided for users new to coding as part of their clinical practice. Of particular importance is that the allergy fraternity bring to light any gaps in allergy coding through the creation of a working group to advise the newly formed International Healthcare Terminology Standards Development Organisation. There is also a role for allergy experts, working in conjunction with government agencies and professional bodies, to determine a recommended set of codes, which will obviate some of the inevitable challenges raised by a very fluid coding structure for those wishing to undertake secondary analysis of health care datasets. [source] The economic burden of depression and the cost-effectiveness of treatmentINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 1 2003Philip S. Wang Abstract Cost-of-illness research has shown that depression is associated with an enormous economic burden, in the order of tens of billions of dollars each year in the US alone. The largest component of this economic burden derives from lost work productivity due to depression. A large body of literature indicates that the causes of the economic burden of depression, including impaired work performance, would respond both to improvement in depressive symptomatology and to standard treatments for depression. Despite this, the economic burden of depression persists, partly because of the widespread underuse and poor quality use of otherwise efficacious and tolerable depression treatments. Recent effectiveness studies conducted in primary care have shown that a variety of models, which enhance care of depression through aggressive outreach and improved quality of treatments, are highly effective in clinical terms and in some cases on work performance outcomes as well. Economic analyses accompanying these effectiveness studies have also shown that these quality improvement interventions are cost efficient. Unfortunately, widespread uptake of these enhanced treatment programmes for depression has not occurred in primary care due to barriers at the level of primary care physicians, healthcare systems, and purchasers of healthcare. Further research is needed to overcome these barriers to providing high-quality care for depression and to ultimately reduce the enormous adverse economic impact of depression disorders.

[source] Comparing methods of determining addition in presbyopesCLINICAL AND EXPERIMENTAL OPTOMETRY, Issue 3 2008Beatriz Antona BSc Background:, The use of plus lenses to compensate for the reduction in the range of accommodation associated with presbyopia, brings the near point of accommodation to a comfortable distance for near visual tasks. Our aim was to compare the tentative near addition determined using the most common procedures with the final addition prescribed in presbyopic patients. Methods:, Sixty-nine healthy subjects with a mean age of 51.0 years (range 40 to 60 years) were studied. Tentative near additions were determined using seven different techniques: dynamic retinoscopy, amplitude of accommodation (AA), age-expected addition, binocular fused cross-cylinder with and without myopisation, near duochrome, and balance of negative and positive relative accommodation. The power of the addition was then refined to arrive at the final addition. Results:, The mean tentative near additions were higher than the final addition for every procedure except for the fused cross-cylinder without initial myopisation and age-expected addition methods. These biases were small in clinical terms (less than 0.25 D) with the exception of the AA procedure (0.34 D). The intervals between the 95% limits of agreement differed substantially and were always higher than ±0.50 D. Conclusions:, All the techniques used displayed similar behaviour and provided a tentative addition close to the final addition. Due to the wide agreement intervals observed, the likelihood of error is high and supports the idea that any tentative addition has to be adjusted according to the particular needs of each patient. Among the methods examined here, we would recommend the age-expected procedure, as this technique produced results that correlated best with the final addition. [source] |
