Population-based utilities for upper extremity functions in the setting of tetraplegia.
Journal of Hand Surgery 2009 November
PURPOSE: People with tetraplegia face substantial physical and financial hardships. Although upper extremity reconstruction has been advocated for people with tetraplegia, these procedures are markedly underused in the United States. Population-based preference evaluation of upper extremity reconstruction is important to quantify the value of these reconstructive procedures. This study sought to establish the preferences for 3 health states: tetraplegia, tetraplegia with corrected pinch function, and tetraplegia with corrected elbow extension function.
METHODS: A computer-based, time trade-off survey was administered to a cohort of 81 able-bodied second-year medical students who served as a surrogate for the general public. This survey instrument has undergone pilot testing and has established face validity to evaluate the 3 health states of interest. Utilities were calculated based on an estimated 20 years of remaining life.
RESULTS: The mean utility for the tetraplegic health state was low. On average, respondents gave up 10.8 +/- 5.0 out of a hypothetical 20 years for perfect health, for a utility of tetraplegia equal to 0.46. For recovery of pinch function, respondents gave up an average of 6.5 +/- 4.3 years, with a corresponding health utility of 0.68. For recovery of elbow extension function, respondents gave up an average of 7.6 +/- 4.5 years, with a corresponding health utility of 0.74.
CONCLUSIONS: This study established the preferences for 2 upper extremity surgical interventions: tetraplegia with pinch and tetraplegia with elbow extension. The findings from this study place a high value on upper-limb reconstructive procedures with tetraplegia.
