Reducing Clabsi Rate Among Icu Patients, Rita L. Walker

Walden Dissertations and Doctoral Studies

Approximately 55% of intensive care unit (ICU) patients require the use of a central venous catheter (CVC). CVCs are often an essential component of care; however, CVCs can create avenues for pathogens to enter the bloodstream and cause a central line-associated bloodstream infections (CLABSI), which can lead to increased mortality and morbidity, prolonged length of stay, increased cost of care, decreased patient satisfaction, and increased workload. In 2017, the CLABSI rate at the project site was 4.3 per 1,000 catheter days as compared to the national rate of 0.8 per 1,000 catheter days. Based on Piaget's theory of constructivism, a …

Modelling Spatial Heterogeneity In The Haemodynamic Response With Implications For Neuroimaging, Russell Gore

Theses

Background: A foundational assumption of neuroimaging is the central volume principle (CVP): the mean transit time of oxygen particles in the brain equals the ratio of blood vessel volume to blood flow. Changes in mean transit time are expected to cause detectable changes in images produced by functional magnetic resonance imaging (fMRI). The CVP assumes a uniform distribution of transit times, but in fact blood vessel volumes are spatially heterogeneous. This thesis examines the implications of spatial heterogeneity for fMRI research.

Methods: An amended form of the CVP that accounts for spatial heterogeneity is developed and parameterised using empirical data. …
