BACKGROUND: The Systematized Nomenclature of Medicine (SNOMED) is an established standard nomenclature for the expression of human and veterinary medical concepts. Nomenclature standards ease sharing of medical information, create common points of understanding, and improve data aggregation and analysis. OBJECTIVES: The objective of this study was to determine whether SNOMED adequately represented concepts relevant to veterinary clinical pathology. METHODS: Concepts were isolated from 3 different types of clinical pathology documents: 1) a textbook (Textbook), 2) the Results sections of industry pathology reports (Findings), and Discussion sections from industry pathology reports (Discussion). Concepts were matched (mapped) by 2 reviewers to semantically-equivalent SNOMED concepts. A quality score of 3 (good match), 2 (problem match), or 1 (no match) was recorded along with the SNOMED hierarchical location of each mapped concept. Results were analyzed using Cohen's Kappa statistic to assess reviewer agreement and chi-square tests to evaluate association between document type and quality score. RESULTS: The percentage of good matches was 48.3% for the Textbook, 45.4% for Findings, and 47.5% for Discussion documents, with no significant difference among documents. Of remaining concepts, 40% were partially expressed by SNOMED and 14% did not match. Mean reviewer agreement on quality score assignments was 76.8%. CONCLUSIONS: Although SNOMED representation of veterinary clinical pathology content was limited, missing and problem concepts were confined to a relatively small area of terminology. This limitation should be addressed in revisions of SNOMED to optimize SNOMED for veterinary clinical pathology applications. 相似文献

In Uganda, control of vector-borne diseases is mainly in form of vector control, and chemotherapy. There have been reports
that acaricides are being misused in the pastoralist systems in Uganda. This is because of the belief by scientists that intensive
application of acaricide is uneconomical and unsustainable particularly in the indigenous cattle. The objective of this study
was to investigate the strategies, rationale and effectiveness of vector-borne disease control by pastoralists. To systematically
carry out these investigations, a combination of qualitative and quantitative research methods was used, in both the collection
and the analysis of data. Cattle keepers were found to control tick-borne diseases (TBDs) mainly through spraying, in contrast
with the control of trypanosomosis for which the main method of control was by chemotherapy. The majority of herders applied
acaricides weekly and used an acaricide of lower strength than recommended by the manufacturers. They used very little acaricide
wash, and spraying was preferred to dipping. Furthermore, pastoralists either treated sick animals themselves or did nothing
at all, rather than using veterinary personnel. Oxytetracycline (OTC) was the drug commonly used in the treatment of TBDs.
Nevertheless, although pastoralists may not have been following recommended practices in their control of ticks and tick-borne
diseases, they were neither wasteful nor uneconomical and their methods appeared to be effective. Trypanosomosis was not a
problem either in Sembabule or Mbarara district. Those who used trypanocides were found to use more drugs than were necessary. 相似文献

服务是一个双向过程,既需要将读者信息图书馆化,也需要将图书馆服务知识读者化。其中,服务知识外化却往往被忽视,基于此,文章把它作为一个专门的问题加以研究,包括它的概念、内容、影响因素及实施。 相似文献
