Summary: A study of 881 twin pregnancies in Brisbane was made to examine the value of hospital bed rest and assess the influence of parity, antenatal complications, and failure of antenatal diagnosis of twins on the rate of prematurity and perinatal mortality. The overall prematurity rate (30–36 weeks) was 30.1% and the perinatal mortality rate 12.2%. There was a marked increase in prematurity and perinatal fetal deaths in 2 groups of patients — those with antenatal complications and fetal abnormalities, and those with a misdiagnosis. Hospital bed rest between 30 and 36 weeks of gestation for the uncomplicated pregnancy provides only a marginal improvement in perinatal mortality; the differences between the rested and non‐rested groups, 4.0% against 6.1%, were not significant. Surprisingly, the rate of prematurity was higher in the rested group (31.9%) than in the non‐rested group (20.1%). The rates of prematurity and perinatal mortality were increased in primigravidae.
