This Doctoral dissertation consists of a research portfolio examining the application of systems engineering techniques to the healthcare environment. The portfolio consists of three final publishable articles submitted to meet the program requirements for the, Doctor of Philosophy in Nursing degree from the University of San Diego, Hahn school of Nursing and Health Sciences. Article one is titled; "Use of a bed projection tool to predict ICU bed needs." This article describes the dissertation research study in which a bed projection tool was piloted on an ICU unit to determine the tool's ability to predict inpatient bed requirements. Article 2 is titled; "Reducing Disruptive Communication in the Health Care Setting: Use of the Crew Resource Model (CRM)."Crew resource is a human factor-engineering model that creates uniform team roles and communication structure. This article advocates the use of this model to assist in dealing with disruptive behaviors by healthcare team professionals.
