Do Guidelines Influence Emergency Department Staff Behaviours and Improve Patient Outcomes? Evaluation of a Multifaceted Intervention for the Implementation of Local Acute Exacerbations of Chronic Obstructive Pulmonary Disease Guidelines.

Introduction Published national guidelines on chronic obstructive pulmonary disease (COPD) highlight the importance of oxygen therapy, bronchodilators, corticosteroids, and appropriate antibiotics during acute exacerbations of COPD (AECOPD). We wished to assess how the implementation of local COPD guidelines affects emergency department (ED) staff awareness, knowledge, the use of such guidelines, and patient outcomes, including treatment failure and rates of return to the ED. Methods This study was conducted at a tertiary hospital ED.

Disambiguating the Stream/Bounce Illusion With Inference.

The ‘stream/bounce’ illusion refers to the perception of an ambiguous visual display in which two discs approach each other on a collision course. The display can be seen as two discs streaming through each other or bouncing off each other. Which perception dominates, may be influenced by a brief transient, usually a sound, presented around the time of simulated contact.

A drug procurement, storage and distribution model in public hospitals in a developing country.

Background: There is growing interest in pharmaceutical supply chains and distribution of medications at national and international levels. Issues of access and efficiency have been called into question. However, evaluations of system outcomes are not possible unless there are contextual data to describe the systems in question.

Judgements of relative direction: the effect of task instructions on spatial recall.

One of the most widely used tasks in the spatial memory literature is the judgement of relative direction (JRD) test. The present investigation examined the hypothesis that standard JRD task demands bias spatial recall. In two experiments, participants' recall of small-scale layouts as measured by standard JRD tests (in which the relationship between objects was employed to establish imagined orientations within the learned scene) was compared with recall as measured by novel JRD tasks.
