Abstract

Improvements in critical care have led to reduced mortality but paradoxically may have promoted survival with increased morbidity. A myriad of functional disabilities range from impairment in lung function, to physical weakness and muscle dysfunction, to a wide range of neuropsychological morbidities, impairment in health-related quality of life, and inability to return to work. Moreover, caregivers, family, and close friends experience burden that may exceed their personal psychological resources. This results in medical complexity that may extend beyond a restrictive syndromic definition. The incremental knowledge contributed by the outcome literature over the past four decades has been limited by the marked heterogeneity in the approach to measuring outcomes. In this chapter, we will review the scope of this issue, assess the historic evolution of outcome measures, and identify factors that influence functional disability after critical illness. Finally, we will explore candidate multidimensional outcome measures for future outcomes and intervention studies designed to deliver risk-stratified, focused, and tailored patient-oriented care.
