Patient Characteristics. During the pre-implementation and
post-implementation periods, 62 % and 60 % of eligible
patients agreed to participate, respectively (Fig. 3).
Participants were younger than non-participants (59.0 and
62.1, respectively, p=0.004); otherwise there were no
significant differences between those who agreed to
participate (N=205) and those who did not (N=131).
Compared to the pre-implementation period, patients
enrolled during the post-implementation period were more
likely to rate their health as excellent or very good and had
made fewer quit attempts, but all other variables were
similar (Table 1).
