tly transferred their health care to a Veterans Affairs (VA) medical c
enter. of the study patients, 56% considered prescription drug costs t
o be the main reason or a major contributing reason for transfer (95%
confidence interval 49% to 63%). The mean out-of-pocket prescription d
rug cost for these patients was $139 per month, compared with $47 per
month for patients for whom drug costs were a minor reason or not a re
ason at all (p < 0.001). Drug costs are a principal reason for patient
s to transfer their health care to the VA.
