The Impact Of Paroxysmal Sympathetic Hyperactivity Following Traumatic Brain Injury On Intensive Care Unit Length Of Stay And Discharge Disposition., Kimberly S. Meyer

Electronic Theses and Dissertations

Paroxysmal Sympathetic Hyperactivity (PSH) is a complication affecting a subset of patients with severe traumatic brain injury (TBI). It is associated with increased morbidity, longer lengths of stay, and delayed recovery (Perkes, Baguley, Nott, & Menon, 2010). The most prevalent signs and symptoms of PSH include unprovoked tachycardia, tachypnea, hypertension, dystonia, and diaphoresis (Lemke, 2007). If untreated, PSH can lead to impaired cerebral blood flow, sub-endocardial damage, dehydration, malnourishment, and contractures (Lemke, 2007). Results from this retrospective study indicate that there is no difference in intensive unit (ICU) length of stay in TBI patients with PSH compared to those without …

A Descriptive Study Of The Effect Of Payer Source On Multiple Longitudinal Outcome Measures Within The Tbi Model Systems National Database Using Longitudinal Hlm Analyses, Melissa Carole Hofmann

Electronic Theses and Dissertations

Using longitudinal data from the TBIMS ND, this study utilized a longitudinal hierarchical linear modeling approach to describe the effect of primary payer source on individual level change in outcomes including the FIM and DRS. To facilitate the use of parametric statistics, Rasch-transformed FIM and DRS scores were utilized; thus approaching an interval level of measurement. The FIM was separated into 3 separate cognitive, mobility, and self-care subscales. In this way, rehabilitation professionals including speech, physical, and occupational therapists for this TBI sample could reference results to inform current clinical practice.

Results indicated that FIM and DRS trajectories were best …
