Evidence Based Nursing Research Project

Introduction: A need for baccalaureate prepared nurses to find and use evidence in practice exists. Whereas using this evidence in practice may be a masters level expectation, current practice demands that baccalaureate prepared nurses acquire a basic understanding of how to use evidence in practice. Nursing students at the senior level have had exposure to critiquing research, however, they have difficulty translating evidence to practice. [See PDF for complete abstract]

Long-term survival after multidisciplinary management of resected pancreatic adenocarcinoma.

INTRODUCTION: Actual 5-year survival rates of 10-18% have been reported for patients with resected pancreatic adenocarcinoma (PC), but the use of multimodality therapy was uncommon in these series. We evaluated long-term survival and patterns of recurrence in patients treated for PC with contemporary staging and multimodality therapy. METHODS: We analyzed 329 consecutive patients with PC evaluated between 1990 and 2002 who underwent resection. Each received a multidisciplinary evaluation and a standard operative approach. Pre- or postoperative chemotherapy and/or chemoradiation were routine. Surgical specimens of 5-year survivors were re-reviewed. A multivariate model of factors associated with long-term survival was constructed. RESULTS: Patients underwent pancreaticoduodenectomy (n = 302; 92%), distal (n = 20; 6%), or total pancreatectomy (n = 7; 2%). A total of 108 patients (33%) underwent vascular reconstruction, 301 patients (91%) received neoadjuvant or adjuvant therapy, 157 specimens (48%) were node positive, and margins were microscopically positive in 52 patients (16%). Median overall survival and disease-specific survival was 23.9 and 26.5 months. Eighty-eight patients (27%) survived a minimum of 5 years and had a median overall survival of 11 years. Of these, 21 (24%) experienced recurrence, 7 (8%) after 5 years. Late recurrences occurred most frequently in the lungs, the latest at 6.7 years. Multivariate analysis identified disease-negative lymph nodes (P = .02) and no prior attempt at resection (P = 0.01) as associated with 5-year survival. CONCLUSIONS: Our 27% actual 5-year survival rate for patients with resected PC is superior to that previously reported, and it is influenced by our emphasis on detailed staging and patient selection, a standardized operative approach, and routine use of multimodality therapy.

Prophylactic mastectomy and oophorectomy for women at risk of breast and ovarian cancer: Incorporating preferences in a decision analysis

The discoveries of the BRCA1 and BRCA2 genes have made it possible for women of families with hereditary breast/ovarian cancer to determine if they carry cancer-predisposing genetic mutations. Women with germline mutations have significantly higher probabilities of developing both cancers than the general population. Since the presence of a BRCA1 or BRCA2 mutation does not guarantee future cancer development, the appropriate course of action remains uncertain for these women. Prophylactic mastectomy and oophorectomy remain controversial since the underlying premise for surgical intervention is based more upon reduction in the estimated risk of cancer than on actual evidence of clinical benefit. Issues that are incorporated in a woman's decision making process include quality of life without breasts, ovaries, attitudes toward possible surgical morbidity as well as a remaining risk of future development of breast/ovarian cancer despite prophylactic surgery. The incorporation of patient preferences into decision analysis models can determine the quality-adjusted survival of different prophylactic approaches to breast/ovarian cancer prevention. Monte Carlo simulation was conducted on 4 separate decision models representing prophylactic oophorectomy, prophylactic mastectomy, prophylactic oophorectomy/mastectomy and screening. The use of 3 separate preference assessment methods across different populations of women allows researchers to determine how quality adjusted survival varies according to clinical strategy, method of preference assessment and the population from which preferences are assessed. ^

The effect of chronic arthritis and hypertension on general well-being

The purpose of the investigation is to elucidate the effect of chronic symptomatic and asymptomatic disease, i.e. arthritis and hypertension, on general well-being, and to quantify the contribution that the duration of the disorder makes to this effect. The data is drawn from the National Health and Nutrition Examination Survey (NHANES I). The results show that arthritics do not have a significant effect on GWB scores while hypertension has a significantly negative impact on GWB. The most striking difference is seen between those without knowledge of hypertension and those recently diagnosed. This difference is attributed to the labeling effect on changes in perceived wellness. ^

The Elegant Simplicity of Family Preservation Practice Legecies and Lessons

An earlier version of this manuscript was prepared for the Chapin Hall invitational seminar on family preservation, The Chapin Hall Center for Children at the University of Chicago, September 16 & 17, 1999. The author wishes to acknowledge the comments and helpful suggestions of seminar participants-Jacqueline McCroskey, Martha Shirk, Fran Jacobs, John Schuerman, Lee Schorr, Charlotte Booth, Kristi Nelson, Susan Kelly, Frank Farrow, and Susan Notkin. These comments, as indeed many of their prior contributions, have had a seminal effect on my thinking about family preservation services over the years. Clark Peters and other Chapin Hall staff deserve special thanks for creating the conditions necessary to produce a lively and productive discussion. As always, Harold Richman, Executive Director of Chapin Hall, and Hermon Dunlap, Smith Professor at the School of Social Service Administration of the University of Chicago, as seminar convenor combined perfectly the skills of gracious host and incisive critic. We in the child welfare field are in his debt for continually raising the level of discourse in our field. In the end, as it should be, the thoughts and opinions in the following paper are wholly my own.
