OBJECTIVE:To compare pregnancy and economic outcomes in women receiving inpatient vs outpatient tocolysis with continuous subcutaneous terbutaline (SQT).
STUDY DESIGN:Identified within a database were women prescribed SQT at 24.0 to 33.9 weeks' gestation following stabilization of an acute episode of preterm labor. Women with cervical dilatation >3 cm, and/or maternal or fetal instability were excluded. Those with prolonged inpatient care were matched 1:1 to those discharged with outpatient follow-up by cervical dilatation, gestational age, and fetal number yielding 90 matched pairs (180 women).
RESULTS:Inpatients had an earlier gestational age at delivery (34.1±2.9 vs 35.8±1.9 weeks, p<0.001), higher preterm birth rate (86.7% vs 74.4%, p ¼ 0.043) and higher overall costs ($56,089±$47,944 vs $25,540±$25,847, p<0.001) than outpatients.
CONCLUSION:Outpatient management resulted in improved pregnancy outcomes at a cost less than that of inpatient management in this analysis of women treated with SQT.
