Mapping the literature of public health and community nursing.

Objectives: The purpose of this study was to identify the journals most cited in public health and community nursing and to determine which databases provide the most thorough indexing access to these journals. This study is part of the Medical Library Association Nursing and Allied Health Resource Section's project to map the nursing literature.

Methods: Two source journals of public health nursing, Public Health Nursing and Journal of Community Health Nursing, were subjected to citation analysis based on Bradford's Law of Scattering.

Transient myocardial ischemia is an independent predictor of adverse in-hospital outcomes in patients with acute coronary syndromes treated in the telemetry unit.

Objective: The purpose of this study was to determine whether transient myocardial ischemia (TMI) is predictive of adverse in-hospital outcomes among patients admitted to a telemetry unit with acute coronary syndrome (ACS).

Design And Setting: The study was designed as a prospective clinical trial in a telemetry unit of a large, urban, university medical center.

Sample: The sample was comprised of adult patients admitted to the telemetry unit for treatment of acute myocardial infarction, unstable angina, or coronary artery disease warranting cardiac catheterization or percutaneous coronary intervention.

Efficacy of 2 strategies to detect body position ST-segment changes during continuous 12-lead electrocardiographic monitoring.

Body positional change is the most frequent cause of false positive ST-segment monitor alarms. This study evaluates 2 strategies to distinguish ST events due to positional change from those due to transient myocardial ischemia: 1) A biosensor device to indicate body position with tick marks on the electrocardiogram (ECG) tracing, and 2) An initially recorded ECG "template" in four positions (supine, right, left, and upright) for subsequent comparison with ST alarm ECGs. A purposive sample of 96 patients on a cardiac telemetry unit was recruited to have both strategies implemented and evaluated.

Comparison of a new reduced lead set ECG with the standard ECG for diagnosing cardiac arrhythmias and myocardial ischemia.

In a few patients, 12-lead electrocardiograms (ECGs) derived from reduced-lead-set configurations do not match the standard ECG. Constructing an ECG from a reduced number of standard leads should minimize this problem because some of the resultant 12 leads would always include "true" standard leads. The purpose of this study was to compare the ability of a new reduced-lead-set 12-lead ECG ("interpolated" ECG) with the standard ECG to diagnose cardiac arrhythmias and acute myocardial ischemia.

Association of transient myocardial ischemia with adverse in-hospital outcomes for angina patients treated in a telemetry unit or a coronary care unit.

Background: Little is known about the frequency or consequences of transient myocardial ischemia in patients admitted to a telemetry unit for treatment of angina.

Objectives: To compare the rate of transient myocardial ischemia in a group of patients with angina treated in a telemetry unit with the rate in a similar group treated in a coronary care unit and to determine if transient myocardial ischemia is associated with adverse in-hospital outcomes.

Methods: Continuous 12-lead electrocardiography was used to monitor changes in the ST segment in 186 patients in the coronary care unit (1994-1996) and 186 patients in the telemetry unit (1997-2000).
