A concept analysis of trust.

Trust is an important and pervasive concept. In nursing, it has been considered primarily from two perspectives. Clinically, it is an important aspect of the nurse-patient relationship. Organizationally, trust is associated with various outcomes and levels of effectiveness. Much of the nursing literature that discusses trust relies upon vague conceptualizations or borrows from other disciplines. The absence of a clear conceptualization of trust has been cited. A core concept of trust is presented which is applicable to nursing in both clinical and organizational settings. Established methods for concept analysis are supplemented by a sequential step model developed by the author. The concept is developed as both process and outcome, and the relationships of the two states to measurement of the concept are identified. The utilization of the core concept in context-specific instances is discussed, and suggestions are made for further research.

Advance directives and opportunities for nurses.

Technical, social, and economic factors are an impetus for expressing end-of-life decisions as advance directives (ADs) including a living will and durable power of attorney. Despite opportunities, nurses do not appear to be widely involved in practice and research regarding ADs. To provide perspectives for nursing participation, the literature was reviewed, and a set of outcomes regarding ADs were identified. The historical background and the ethical issues associated with ADs are examined. Appropriate roles for nurses with respect to ADs are suggested. Research and practice opportunities are identified. The databases reviewed were the Cumulative Index to Nursing and Allied Health Literature from 1983 to January 1996, and MEDLINE, from 1985 to January 1996.

Ectopic pregnancy.

Ectopic pregnancy (EP) is a serious and increasing health problem in the United States and other countries. In the United States, it accounts for 15 percent of maternal deaths, 75 percent of which are estimated to be preventable, and its incidence has increased more than 100 percent for some demographic groups over the past 10 years. There are a number of potential contributing factors to ectopic pregnancy; however, their relationship to actual incidence is unclear in some instances. Nonspecific symptoms increase the difficulty of diagnosis. This article presents an overview of the significance of the problem, contributing risk factors, clinical presentation, diagnostic modalities, treatment and nursing implications.
