This study consisted of secondary analyses of data obtained from
a multi-center, two-arm, parallel cluster randomized trial conducted
in a network of the 12 family practice teaching units (units of
randomization) affiliated with the Department of Family Medicine
and Emergency Medicine at Universite´ Laval in six different regions
of the Province of Quebec, Canada. The design, methods, and
findings of this trial have been described elsewhere [21–23]. The
trial was conducted in three phases: a) baseline data collection
(physician and patient recruitment) from July through October
2010; b) intervention (training of physicians in the experimental
group in DECISION+2, a training program in SDM) in November
2010, and c) post-intervention data collection (patient recruitment)
from November 2010 through April 2011.
