Racial disparities in access and cost for commonly prescribed infertility medications may contribute to disparities in pregnancy outcomes

Abstract

To determine if disparities in cost and access to commonly prescribed infertility medications exist in predominately minority neighborhoods. A prospective phone survey of pharmacies in Bronx and Westchester counties of New York State was done to assess the availability and cost of commonly used infertility medications. Demographic data for each county was defined by U.S. Census Data. Pharmacies were categorized by ZIP code and the availability and cost for medication determined and compared to the racial composition of that ZIP code. 121 pharmacies were surveyed. Availability and cost of 15 medications commonly used to treat infertility were obtained. Data were stratified by racial demographics and analyzed with Fishers exact test, ANOVA, or Chi-square test for trend. Reduced availability of Clomiphene citrate (CC) was observed in the Bronx pharmacies (79 vs. 89%, P<0.01), an area populated by >80% blacks and Hispanics. Choriogonadotropin alpha (CGa) was not available in the Bronx (0 vs. 15%, P<0.01). There was also a significant decrease in the trend for the availability of both CC and CGa when the percentage of blacks increased from 10 to >40% (53 vs. 33%, P<0.01) compared to no change for increasing percentage of whites. In contrast the availability of CGa was highest in areas with > 80% white compared to areas with >40% black or Hispanic (15 vs. 0%, P<0.01). Interestingly as the percentage of the black population increased the cost of CGa significantly decreased ($133 ± 14 vs. $99 ± 10, P<0.01) and there was also a trend for reduced CC costs. Racial disparities in infertility outcomes are linked to delayed treatment and referral patterns or inadequate access or utilization of subspecialty care. These data suggest disparities in the availability of commonly used medications but not increased cost may adversely affect compliance and contribute to suboptimal treatment and delayed referral to subspecialist.
