We sought to identify risk factors associated with the time to febrile neutropenia in patients with intermediate-grade, non-Hodgkin's lymphoma (NHL) who were receiving treatment with CHOP chemotherapy. Data were collected from 12 community and academic oncology practices participating in the Oncology Practice Pattern Study between 1991 and 1999. We reviewed the medical records of 577 intermediate-grade NHL patients who received initial CHOP chemotherapy and evaluated risk factors associated with time to first febrile neutropenic event. A febrile neutropenic event was defined as a body temperature of > 100.6 degrees F and an ANC nadir < 1000/mm3. A total of 160 patients experienced 224 febrile neutropenic events. The risk of febrile neutropenia was significantly associated with age > or = 65 years (p = 0.001), cardiovascular disease (p = 0.020), renal disease (p = 0.006), baseline hemoglobin < 12 g/dl (p = 0.018), > 80% planned average relative dose intensity (ARDI; p = 0.018), and no prophylactic colony-stimulating factor (CSF) use (p = 0.046). First febrile neutropenic events occurred by day 14 of cycle 1 in one-half of patients experiencing febrile neutropenia. In multivariate analysis, the risk of febrile neutropenia remained significantly associated with age > or = 65 years (HR = 1.65, 95% CI: 1.18-2.32), renal disease (HR = 1.91. 95% CI: 1.10-3.30), cardiovascular disease (HR = 1.54, 95% CI: 1.02-2.33), baseline hemoglobin < 12 g/dl (HR = 1.44, 95% CI: 1.04-2.00), > 80% planned CHOP ARDI (HR = 2.41, 95% CI: 1.30-4.47), and no CSF prophylaxis (HR = 2.13, 95% CI: 1.20-3.76). Such a model may permit the identification of patients at greatest risk of febrile neutropenia and, therefore, candidates for the selective prophylactic use of the hematopoietic growth factors. 相似文献

This paper considers the issue of nursing science. Nursing, as an art, has long been accepted as integral to nursing. Nursing, as a science, however, is a more recent concept. Nursing science is viewed as a threat to the profession by its opponents, while the proponents of nursing science see it as a promise for advancement of the discipline. This paper examines the issue of nursing science by looking at its history and development, the definition of science, and five factors critical to the nursing science issue. The author concludes that nursing science is, in varying respects, both a threat and a promise. It is clear that the preponderance of evidence favours the promise nursing science holds for the profession of nursing. It is not a matter of choosing either art or science, but rather skillfully blending both for the betterment of nursing. Both art and science are necessary in nursing--neither, however, is sufficient. 相似文献
