Abstract

This study introduces an index for quantifying the health status and changes in patients within an adult intensive care unit (ICU), driven by the need to evaluate the impact of telemedicine on healthcare delivery. The ICU Patient Assessment Profile consists of twelve observable parameters encompassing neurological, respiratory, cardiovascular, and renal functions. Each parameter receives a score, and weights derived through stepwise multiple regression and nonlinear optimization create a severity of illness index, SEVILL, applicable to both neurologic and non-neurologic patients. This index enables comparisons of individual patients over time and among similar patients, facilitating assessments of recovery rates. The thesis is structured into five chapters covering problem formulation, the assessment profile, mathematical modeling, application, and future research directions. Potential applications of the index include outcome prediction, staffing decisions, and performance comparisons across ICU units.
