Pneumatic tube transport of blood samples – an update

Hemolysis associated with pneumatic tube system transport for blood samples

OBJECTIVE The frequency of hemolysis of blood samples may be increased by transport in a pneumatic tube system. The purpose of this study was to evaluate the effect of pneumatic tube system transport on hemolysis of blood samples. METHODS Blood samples were transported from the emergency department to the hospital laboratory manually by hospital staff (49 patients) or with a pneumatic tube sy...

Assessing Pneumatic Tube

The October 2011 issue of Clinical Chemistry highlights the importance of monitoring pneumatic tube systems (PTSs) to control preanalytical factors that may affect laboratory results (1, 2 ). Two important themes emerge: (a) the possible requirement of morefrequent monitoring if the PTS produces changes in the 3-axis acceleration (i.e., forces) and (b) consideration for specific populations of ...

Models of Emergency Departments for Reducing Patient Waiting Times

In this paper, we apply both agent-based models and queuing models to investigate patient access and patient flow through emergency departments. The objective of this work is to gain insights into the comparative contributions and limitations of these complementary techniques, in their ability to contribute empirical input into healthcare policy and practice guidelines. The models were develope...

rone metabolites in the plasma of these patients. The effect of this is that a commonly used automated aldosterone immunoassay overestimates plasma aldosterone in renal impairment, and the magnitude of this bias increases with the worsening of renal function. In comparison to results for individuals with normal renal function, the assay overestimates aldosterone on average by 129% in hemodialys...
