Abstract
The purpose of this pilot study was to determine the role of foetal fibronectin (fFN) testing in women presenting to hospital with symptoms of preterm labour in reducing the hospital admissions, without significantly increasing the risk of preterm birth and neonatal respiratory distress syndrome. Women with symptoms of preterm labour were assigned randomly to receive fFN (n = 44) or to preterm labour management without fFN (n = 44). In the testing arm, the result of the test was revealed to the clinician. Clinical outcomes were compared in the two groups. The time period covered by the randomised controlled trial (RCT) was from December 2007 to March 2009. The RCT was conducted in two large maternity units in the west of Scotland, one in Glasgow the other in Ayrshire. All the women with fibronectin positive got admitted while only 32.4% of the fibronectin negatives were admitted (P = 0.002). There was a significant difference in the mean length of stay between the fibronectin positives which was 47.17 h, and the negatives which was 12.9 h (P = 0.018). Overall the control and testing arms did not differ in respect to admissions and length of stay. 5 out of 7 positives and 11 out of 37 negatives had corticosteroids (P = 0.089). 2 out of 7 positives and 1 out of 37 negatives had tocolytics (P = 0.073). Those who had the fFN test done were less likely to be admitted in the hospital and had a shorter length of stay, without any increase in the adverse maternal or foetal effects, avoiding unnecessary admissions.
