Cost comparison of immediate one-stage and tissue-expander breast reconstructions after mastectomy in commercially insured patients

Objective: Growing acceptance of nipple-sparing mastectomy and rising rates of prophylactic mastectomy due to genetic findings make immediate one-stage implant breast reconstruction an attractive option for many American women facing post-mastectomy breast reconstruction. We compared medical services utilization and cost of immediate one-stage reconstruction with that of the more common tissue-expander (TE) breast reconstruction. Design: Retrospective administrative claims database analysis. Methods: We obtained commercial insurance claims on patients in the U.S. who had undergone onestage or TE post-mastectomy implant breast reconstructions in 2008, and we compared 18-month results in terms of the frequency and cost of return visits for additional procedures and/or for the treatment of complications. Return visits were categorized as planned, planned with revision, or unplanned. Results: Among 1,316 immediate implant breast reconstructions, 95 (7%) were one-stage procedures and 1,221 (93%) were TE reconstructions. The data showed a modest, nonsignificant trend toward fewer return visits after one-stage reconstruction versus TE reconstruction (191 vs. 242 visits per 100 patients, respectively; relative risk [RR]: 0.95). Patients with TE reconstructions returned more often for planned returns and planned returns with revisions. Patients with one-stage reconstructions returned more often for unplanned events. The total costs over 18 months were $34,839 and $39,062 for one-stage and TE reconstructions, respectively, for a difference of -$4,223 (P = 0.38). The initial reconstruction, including the mastectomy, accounted for 64% of the 18-month costs with one-stage reconstructions and for 54% of the 18-month costs for TE reconstructions. Conclusion: Costs and utilization trended lower over 18 months for one-stage versus TE reconstructions following post-mastectomy breast reconstructions but did not achieve statistical significance.
