Objectives: We assessed the effectiveness of ambulatory tocodynamometry in reducing the preterm delivery rate in women at risk of preterm delivery such as women with risk factors and women previously hospitalized and discharged.
Study design: In four public maternity units these women were randomly allocated to two groups: 84 had home uterine activity monitoring and daily midwife contact and 84 were given the standard care for high-risk women, which generally includes home visits by community midwives.
Results: The proportion of deliveries before 37 weeks' gestation was slightly higher in the monitored group than in the control group (32% vs 22%). The corresponding odds ratio was 1.7 (95% confidence interval: 0.9 to 3.5).
Conclusion: Although the sample was small, these results suggest that home uterine activity monitoring was probably not beneficial to the population studied, or at least that any benefit would have been too small to justify extending this monitoring in this high-risk population.
