Abstract
IntroductionThe APOSTEL-II trial was a multicenter randomized placebo-controlled trial, assessing the effectiveness of maintenance tocolysis with nifedipine. The trial showed maintenance tocolysis not to have an effect on perinatal outcome. Objective of the current study is to evaluate the effect of a negative trial on the length of hospital admission of women with threatened preterm labor. Materials and methodsWe evaluated length of hospital admission of all patients admitted with threatened preterm labor with a gestational age <32 weeks in 8 perinatal centers that participated in the APOSTEL-II trial. We studied only the first admission with threatened preterm labor, readmissions were excluded. We distinguished between the period before, the period during and the period after the trial. In a subgroup analysis, we differentiated for the group of women who delivered and for the group of women who did not deliver during the initial admission. ResultsThe mean length of hospital admission was 9.3 days before the start of the trial, 8.4 days during the recruitment period and 8.1 days after the trial was completed. The difference in mean length of hospital admission before and during the recruitment period was significantly different (p<001). CommentsThe length of hospital admission of women with threatened preterm labor is found to be reduced during the recruitment period of the APOSTEL-II trial. This shows that the conduct of a randomized controlled trial itself has the potential to change daily practice.
