Table 3 Costs for management pathways, derived from decision tree, Figure 1

From: Reducing the cesarean delivery rates for breech presentations: administration of spinal anesthesia facilitates manipulation to cephalic presentation, but is it cost saving?

Pathways for breech management Management procedures (ECV with/without spinal, subsequent VD or CD) Unit cost NIS CD/VD rates after ECV[19],[20] Relative probability (95% CI) Relative cost NIS (CD rate 16% after successful ECV)
Pathway A
No ECV CD 11670.54 100%  
    Total pathway A 11670.54
Pathway B
B1 ECV (failure), CD 12630.75 55.2% (0.40-0.64) 6972.17
B2 ECV (success), CD 12630.75 7.2% (0.03-0.16) 909.41
B3 ECV (success), VD 5070.44 37.6% (0.26-0.49) 1906.49
    Total pathway B 9988.07
Pathway
C1 ECV + spinal, CD 13057.51 23.9% (0.15-0.35) 3120.74
C2 ECV + spinal, CD 13057.51 12.2% (0.06-0.21) 1593.02
C3 ECV + spinal, VD 5497.2 63.9% (0.52-0.75) 3512.71
    Total pathway C 8226.47
  1. Key: Costs are derived from Table 1 unit costs and% of each pathway occurring.
  2. CD = cesarean delivery, VD = vaginal delivery, ECV = external cephalic version, CI = confidence interval.
  3. Pathway A = no ECV, Pathway B = ECV without spinal anesthesia, Pathway C = ECV with spinal anesthesia.
  4. For CI calculation, the denominator is 67 (Table 3) [19, 20].
