Health status in veterans undergoing noninvasive lower extremity arterial evaluation.
The health status of outpatients (n = 299) undergoing lower extremity arterial Doppler studies (LES) in a Veterans Affairs Medical Center-based vascular laboratory was assessed from 9/95 through 6/96 using the SF-36 Health Survey. The purpose of this study was to compare health status of these outpatients to national norms and to determine whether Doppler-derived ankle/brachial indices (ABI) correlated with the eight health concepts measured by the SF-36 Health Survey. Physical functioning (PF), role limitations by physical illness (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role limitations by emotional illness (RE), and mental health (MH) were more impaired in study patients (65.9 +/- 9.6 years of age) undergoing LES than national norms for males >/=65 years old (P < 0.0001). In fact, each health concept was below the 25th percentile of the national norms. PF was 33.4 +/- 22.4 for outpatients compared to the national norm of 65.8 +/- 28.3. Physical functioning was the only SF-36 health concept defined above which correlated with lowest ABI (r = 0.15; P = 0.012), adjusting for age but not comorbidities. Veterans undergoing only carotid duplex during the study period (n = 169) were compared to the veterans undergoing only LES (n = 251) during the study. PF, RP, BP, GH, VT, SF, and RE were significantly more impaired in those undergoing only LES compared with carotid duplex (P < 0.05). Veteran outpatients referred to a vascular laboratory have broad-based and profound impairments in health status. In addition, only physical functioning correlated with ABI, a measure of lower extremity arterial disease severity.
