Objective To identify the current status of specialist preterm labour ( PTL ) clinics and identify changes in management trends over the last 5 years following release of the NICE preterm birth ( PTB ) guidance. Design Postal Survey of Clinical Practice. Setting UK . Population All consultant‐led obstetric units. Methods A questionnaire was sent by post to all 187 NHS consultant‐led obstetric units. Units with a specialist PTL clinic were asked to answer a further six questions defining their protocol for risk stratification and management. Main outcome measures Current practice in specialist PTL clinics. Changes in treatment trends over 5 years. Results Thirty‐three PTL prevention clinics were identified, with 73% running weekly. NHS staff (84%) have replaced university staff as the lead clinicians (from 69% in 2012 to 21% in 2017), suggesting this clinic has become increasingly integrated with standard care for women at the highest risk of PTB . There has been a large shift from nearly half of clinics offering cerclage as primary treatment for short cervix to offering more choice (30%) between at least two of cerclage, vaginal progesterone or pessary and combinations of primary treatments (18%), demonstrating more equipoise among clinicians regarding therapies for short cervix. Conclusions Over 5 years, there has been a 44% increase in the number of specialist PTL clinics in the UK . Although there is a better consensus over the target high‐risk population, there is increasing heterogeneity among first‐line treatments for short cervix. Tweetable abstract UK PTB prevention clinics have increased by 44% over 5 years, with increasing clinical equipoise to best Rx for short cervix.
