BACKGROUND: Efforts to reduce the wastage of blood components are necessary because of the shortage of blood components. To find ways of reducing the blood component wastage, we monitored the trends and reasons for wastage and we analyzed this data. METHODS: We have investigated and analyzed the amount and reasons for wastage from 2003 to 2005 by reviewing the wastage statements, and the information on these wastage statements was classified according to several aspects. Ouestions about the reasons for wastage and the methods for reducing such wastage were created and these were widely distributed to the doctors and nurses working at Pusan University Hospital. The results of the survey were analyzed. RESULTS: The wastage rates of blood component from 2003 to 2005 had a tendency to slightly decline: 1.49% in 2003, 1.26% in 2004 and 1.23% in 2005. The most frequent reason for wastage was the improvement in the patient's condition and the second most frequent reason was death of the patient. The favorite answers for the question about the most likely reason for wastage were related to different aspects of medicine, and also to the improvement in the patient's condition (52.6%) and the death of patient (22.6%) for the aspect of blood management, the most frequent answers were overcharge (43.3%) and delay of blood returning (17.7%). The analysis of the pattern of wastage showed that only 5 departments were responsible for 71.5%~78.1% of the wastage. CONCLUSION: Systematic and active management of the transfusion process, along with intensive cooperation of clinicians, is needed to prevent a considerable amount of blood component wastage.

PURPOSE: This study was designed to explore what experiences nurses had while caring and providing emotional support for patients. METHODS: Participants were eight nurses working at hospitals for more than one year. Data were collected from June, 2006 to January, 2007 through in-depth interview by using tape-recordings. Data were analysed with the phenomenological method proposed by Colazzi(1978). RESULTS: From significant statements, 4 clustered themes, 7 themes and 23 sub-themes were extracted from the essential meaning of the emotional experience of hospital nurses. The 4 clustered themes were 'movement of mind', 'affection and service for patients', 'worthwhile and conflict' and 'control oneself'. The 7 themes were 'special feeling', 'rapport formation', 'consideration', 'human interaction', 'value discovery', 'loss of volition', and 'keep to balance'. CONCLUSION: Although nurses had tough experiences for providing care for patients' emotional support, they had also experienced spiritual maturity from its experience. The result of this study would contribute for nurses not only to care for patients who need emotional support but also to develop knowledge in nursing.

Noninferiority trials test whether a new experimental treatment is not unacceptably less efficacious than an active control treatment already in use. With continuous improvements in health technologies, standard care, and clinical outcomes, the incremental benefits of newly developed treatments may be only marginal over existing treatments. Sometimes assigning patients to a placebo is unethical. In such circumstances, there has been increasing emphasis on the use of noninferiority trial designs. Noninferiority trials are more complex to design, conduct, and interpret than typical superiority trials. This paper reviews the concept of noninferiority trials and discusses some important issues related to them.
