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 />

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 />
