N=173,219 observations.

All continuous variables are divided by their standard deviation.

Time trend=1 in 1998, 2 in 1999, and so forth through 2005.

State dummies also included (not shown).

p-values use standard errors adjusted using the Huber–White robust estimator.

FTE, full-time equivalent; ADL, activities of daily living; RNs, registered nurses; LPNs, licensed practical nurses; NAs, nurse aides.
