increased LOS. There were no gender differences, but American Indians
had shorter LOS than Whites or African Americans. History of
cigarette smoking, advanced age, and unclear diagnosis were also associated
with longer LOS.
Conclusion: The severity of the stroke, co-morbidities, and prestroke
status of a stroke survivor may contribute to the LOS of stroke
patients and affect their overall post-stroke outcome. Although biological
factors are most influential, social and psychological factors
also played a role.

BACKGROUND: KPS is frequently used to assess function in
older patients; however, it is prone to observer bias and has limited
ability to detect abnormalities in other GA domains. This study explores
the relationship between KPS and pKPS and their association
with measures of GA domains.
METHODS: Data from the Carolina Senior registry which includes
the North Carolina Cancer Hospital and community affiliates
for patients ≥65 years were analyzed using Fisher’s Exact and
weighted kappa (κ) statistics. Patients completed a predominantly
self administered GA (Hurria et al, Cancer 2005) which included rating
scales for both KPS and pKPS.
RESULTS: The 386 evaluable enrollees had median age: 73
(range 65-97); and were 81% female; 89% white; 55% married; 83%
retired; 72% at least some college education; 97% a cancer diagnoses.
There was fair agreement [κ=0.26 (95% CI 0.18-0.33)] between
KPS and pKPS for patients with scores ≥ 40% (Fig. 1). There
were statistically significant associations between KPS and pKPS
scores
