-The safety <strong>of</strong> an active management protocol<br />
was confirmed. No substantial decrease<br />
in the rate <strong>of</strong> Caesarean delivery was observed.<br />

at time <strong>of</strong> onset <strong>of</strong> labor<br />
-ITT analysis: data from 1915 patients; Caesarean<br />
rate was 19.5% in active mgmt group and 19.4% in<br />
usual care group; results unchanged when adjusted<br />
for baseline characteristics or epidural anesthesia<br />
use; Caesarean rates due to failure to progress were<br />
7% in active mgmt and 8% in usual care groups<br />
-Subgroup analysis:<br />
a. 33% <strong>of</strong> the active mgmt group and 35% <strong>of</strong> the<br />
usual care group developed medical complications<br />
or had labor induced and were ineligible; the protocol-eligible<br />
subgroup included 678 in active mgmt<br />
and 585 in usual care; 633 in active mgmt group<br />
were treated according to protocol<br />
b. Groups did not differ at baseline<br />
c. Active mgmt group had more frequent vaginal exams,<br />
had membranes ruptured artificially more <strong>of</strong>ten<br />
(and earlier), were more likely to receive oxytocin,<br />
had higher maximal dose <strong>of</strong> oxytocin, requested<br />
epidural anesthesia less <strong>of</strong>ten (p2 hrs (>3 hrs if<br />
epidural catheter)<br />
-Usual Care Group: no constraints<br />
on physicians<br />

shorter labor in active mgmt group (6.2 hrs vs. 8.9<br />
hrs)<br />
e. Lower incidence <strong>of</strong> maternal fever in active mgmt<br />
group (RR=0.6); other complications were same for<br />
both groups; no differences in infants' outcomes<br />
