Introduction Centralization of very preterm deliveries to level 3 hospitals is recommended to improve infant survival and prevent brain injury. We studied the clinical practices of centralization from level 2 to level 3 hospitals in cases of threatening very preterm delivery in Finland.
Materials and methods Obstetricians in all 16 level 2 hospitals in Finland were invited to participate in an online survey regarding antenatal transfer to level 3 hospitals among women with threatened delivery below 32 gestational weeks. We report clinical thresholds used as indications and contraindications for antenatal transfers, and logistical factors related to transfers.
Results Twelve out of 16 (75%) hospitals completed the survey. The lower gestational age threshold for antenatal transfer ranged from 22 + 0 to 23 + 0 weeks. All hospitals regarded preterm premature rupture of membranes, chorioamnionitis, and severe pre-eclampsia as indications for antenatal transfer to a level 3 hospital. Most hospitals reported transferring women in spite of regular contractions (interval over 5 min) or cervical dilatation up to 4 cm. Suspicion of placental abruption, abnormal cardiotocography tracing and poor maternal condition were the most frequently reported contraindications for antenatal transfer. The time to arrange antenatal transfer was less than 2 h in all hospitals, and overcrowding of level 3 hospitals rarely hindered antenatal transfer.
Conclusions Successful centralization of very preterm deliveries is reached in Finland by rapid and active antenatal transfers. This study identified clinical thresholds used by obstetricians in a setting of long distances and high centralization rate.
