RESEARCH QUESTION: Is household income or IVF insurance coverage associated with live birth outcomes in infertile women undertaking IVF? DESIGN: Retrospective cohort study in an academic hospital, including patients residing in New York State undergoing a frozen single embryo transfer at the study IVF centre between 1 January 2017 and 31 December 2018. Only the first embryo transfer per patient was included. Patients were stratified by tertiles of estimated income using home zip code census data: <$85,888 (n = 348), $85,888-122,628 (n = 348) and >$122,628 (n = 350). A second analysis stratified patients by IVF insurance coverage or no coverage. The primary outcome was live birth. Modified Poisson regression with robust error variance adjusted a priori for age, preimplantation genetic testing and previous fresh embryo transfer estimated the relative risk of outcomes with a 95% confidence interval. RESULTS: A total of 1046 patients were included. Live birth rate was similar among all three income tertiles. Secondarily, the pregnancy rate and pregnancy loss rate were also similar among all three tertiles. In the IVF insurance coverage analysis, live birth rate was similar between patients with and without IVF insurance coverage. Secondarily, the pregnancy rate and pregnancy loss rate were also similar among these two groups. CONCLUSION: Overall, neither median household income nor IVF insurance coverage of patients undergoing single frozen embryo transfer was associated with pregnancy, pregnancy loss or live birth outcomes. Lower income, relative to the patient cohort, and lack of insurance coverage are well-described barriers to accessing infertility evaluation and treatment. However, once treatment is initiated, the current results suggest that these variables do not influence pregnancy and live birth outcomes in infertile patients.
