Impact of VA-Purchased Community Care on Polypharmacy and Potentially Inappropriate Medication Use in Older Adult Veterans.

The sample included 399,250 Veteran-year observations, of which 226,157 (56.6%) were 36-39 miles and 173,093 (43.4%) were 41-44 miles from the nearest eligible VA facility.

There were no discontinuities in proportions of Veterans filling ≥ 5 unique medications (-0.25 percentage points [pp]; 95% CI, -0.84 to 0.34), ≥ 10 medications (-0.55 pp.; 95% CI, -1.24 to 0.14), ≥ 1 medication on the Beers list (-0.02 pp.; 95% CI, -0.63 to 0.59), or ≥ 1 high-risk drug-drug interaction (-0.05 pp.; 95% CI, -0.17 to 0.07).
