A critical analysis of the potential contribution of Orem's (2001) self-care deficit nursing theory to contemporary coronary care nursing practice.

BACKGROUND: Over the last three decades, nurse theorists have strongly advocated the use of conceptual models of nursing to guide nursing practice. Within coronary care units, conceptual model-based care has had inconsistent application and is currently challenged by contemporary approaches such as pathways of care. AIMS: This paper aims to critically analyze the use of Orem's self-care deficit nursing theory as a modus operandi to effectively meet the needs of hospitalized patients in coronary care. RESULTS: Although complex both in the language and construction, the self-care model , provides a comprehensive and holistic approach to the care of people in coronary care. CONCLUSIONS: This paper highlights the potential contribution the application of the self-care deficit nursing theory to the coronary care setting from a philosophical and practical perspective. Orem's conceptual model of nursing and current practice in coronary care units share certain similarities that render a useful model for use in practice. However, while it is recommended for consideration for use in both practice and educational settings, further empirical work is required in the area, together with realistic and practical application of the theory to practice in a way that embraces contemporary notions.

The Community Client Need Classification System - a dependency system for community nurses.

AIM: The aim of this paper was to discuss the predictive validity and reliability of the Community Client Need Classification System (CCNCS), the results of using this tool and public health nurses' satisfaction with the system. BACKGROUND: Public health nurses provide the majority of community nursing services in Ireland. The traditional method of measuring workload in the community is based on recording the number of visits. The revised Easley-Storfjell instrument for Caseload/Workload Analysis was modified for the Irish context and permission from the authors was sought to use it in this study and was thus named the CCNCS. METHODS: A convenience sample of 29 public health nurses used the CCNCS to classify 1352 clients for 2 weeks. RESULTS: The elderly and child health groups accounted for the majority of the nurses' direct and indirect time. Predictive validity analysis demonstrated a positive relationship between needs level and nursing time. Nurses reported that the CCNCS was useful in predicting the needs of new and existing clients. CONCLUSIONS: This classification system, albeit in the first draft of its revised form, was perceived by the chosen sample of public health nurses as useful in measuring their workload. Further research is required to ascertain the reliability of the modified classification system with a larger sample size.

Family-based association studies of lipid gene polymorphisms in coronary artery disease.

Dysfunction of lipid-metabolizing proteins is implicated in the pathogenesis of coronary artery disease. Single nucleotide polymorphisms in genes that encode sterol regulatory binding protein-1a, adenosine triphosphate binding cassette-A1, hepatic lipase, lipoprotein lipase, and cholesteryl ester transfer protein were assessed as potential markers of disease susceptibility in a family-based study of 1,012 patients from 386 families. Association between single nucleotide polymorphisms and coronary artery disease was tested by the combined transmission disequilibrium test/sib transmission disequilibrium test and pedigree disequilibrium test. After Bonferroni's correction, the pedigree disequilibrium test demonstrated significant excess transmission (p <0.0083) to affected patients of the hepatic lipase -514 T allele, which suggests that this may constitute a novel disease-susceptibility locus.

Acute onset dysphagia associated with an intramural oesophageal haematoma in acquired haemophilia.

A 78-year-old man presented with a 5-day history of epistaxis and spontaneous bruising, and a 2-day history of acute dysphagia. Barium swallow, computerized tomography scan of the chest and upper gastrointestinal endoscopy were suggestive of an upper oesophageal tumour, although biopsies failed to confirm this. Investigations including a raised activated partial thromboplastin time led to the detection of an inhibitor causing functional factor VIII deficiency. Following treatment with intravenous human immunoglobulin, oral prednisolone and oral cyclophosphamide, the patient's dysphagia resolved. There was a resolution of the findings seen at the initial endoscopy and on computerized tomography scan of the chest, consistent with an oesophageal haematoma. Follow-up endoscopy failed to detect recurrence or an aetiological factor.
