abstract

  • PURPOSE: To undertake an economic analysis of repeat Caesarean births in low-risk women (LRW) not in labour in Ontario who delivered at 37-38 weeks (<39 weeks) vs. 39-40 weeks (≥39 weeks) gestation. METHODS: Data from the Better Outcomes Registry & Network (BORN) Information System for fiscal years 2012-2013 and 2013-2014 meeting the definition for elective repeat CS (ERCS) for LRW between 37 and 40 weeks gestation. Costs were obtained from the Ottawa Hospital Data Warehouse and applied through to discharge. RESULTS: For April 2012 to March 2013, we extracted 3637 ERCS dyads at <39 weeks and 3282 dyads at ≥39 weeks. There were 334 NICU admissions at <39 weeks (0.92%) and 235 at ≥39 weeks (0.72%). Average neonate cost was $1247.99 (<39 weeks) vs. $1200.77 (≥39 weeks)-a difference of $47.22. Average dyad cost was $3608.92 (<39 weeks) vs. $3577.04 (≥39 weeks)-a difference of $31.88 per birth. If these births were delayed to ≥39 weeks, net savings of $173 864 and $115 947 annually would be realized on "baby only" and "dyad" costs, respectively. For April 2013 to March 2014, we extracted 2875 ERCS dyads at ≤39 weeks and 3892 dyads at ≥39 weeks. There were 216 NICU admissions ≤39 weeks (0.75%) and 224 at ≥39 weeks (0.58%). Average neonate cost was $1268.56 (<39 weeks) vs. $1126.56 (≥39 weeks)-a difference of $142.00 per birth. Average dyad cost was $3605.70 (≤39 weeks) vs. $3456.61 (≥39 weeks)-a difference of $149.08. If these births were delayed to ≥39 weeks, net annual savings of $404 842 and $428 605 would be realized on "baby only" and "dyad" costs respectively. CONCLUSIONS: Restricting repeat CS in LRW to ≥39 weeks is a cost-effective strategy.
