How can we recognize continuous quality improvement?

OBJECTIVE Continuous quality improvement (CQI) methods are foundational approaches to improving healthcare delivery. Publications using the term CQI, however, are methodologically heterogeneous, and labels other than CQI are used to signify relevant approaches. Standards for identifying the use of CQI based on its key methodological features could enable more effective learning across quality i...

How many can you see at a glance? The role of attention in visual enumeration

There is considerable controversy as to how the brain extracts numerosity information from a visual scene and as to how much attention is needed for this process. Traditionally, it has been assumed that visual enumeration is subserved by two functionally distinct mechanisms: the fast and accurate apprehension of 1 to about 4 items, a process termed “subitizing”, and the slow and error-prone enu...

How many positions can we perceptually encode, one or many?

Here we show that our sensitivity for discriminating relative position across the visual field is limited. In experiment 1 we show that we are much worse at detecting a texture defined by the relative position of elements within an array than would be expected if we had access to multiple estimates of relative position across the visual field. In experiment 2 we show that human performance is i...

How many times can we defibrillate a patient ?

Ventricular fibrillation (VF) is the cardiac rhythm disturbance which is the number one cause of cardiac arrest. Most common etiologic factor is the coronary heart disease [1]. VF may occur due to acute myocardial ischemia, infarction or a scar tissue formed previously because of a prior myocardial infarction (MI). Defibrillation is the first line therapy. Antiarrhythmic drugs should also be ad...
