Design: Cross-sectional study. Setting: reproductive years (women 20 44 years; men 20 49 years) based on US Census 2000 data. Assisted reproductive technology registered with the Society for Assisted Technology (SART) in 2005. Main Outcome Measure(s): s within service area served by in- state ART as defined by a 60-minute travel time along road networks from each center. Result(s): Service areas for 387 of 390 ART were calculated. Fourteen states had some form of mandated coverage. Underserved states included Alaska, Montana, Wyoming, and West Virginia. The northeastern United s had the greatest percentage of overserved population with 66% 100% study population within 60 minutes of an ART center. Female age stratification showed the highest age group (35 44 years) per state in northern New England and the youngest in Utah and District of Columbia. Median total study population within 60 minutes of an ART center in their own state was higher in mandated versus nonmandated states. Conclusion(s): Disparity of access to care for infertility services exists from the standpoint of population service areas for ART and state-mandated coverage. Female age stratification may help anticipate future need for services with existing resource distribution. (Fertil Steril Ò 2010;93:745 61. Ó2010 by American Society for Medicine.) Key Words: ART, SART, population, service areas, mandated coverage Infertility for a couple in the United s is defined as the inability to achieve a pregnancy within 1 year of unprotected intercourse. Nearly 85% of couples achieve a pregnancy in this time frame, leaving 15% of couples potentially seeking reproductive assistance (1, 2). The 2002 National Survey of Family Growth showed that among 62 million women of reproductive age (15 44 years), 1.2 million (2%) had an infertility-related medical appointment within the previous year. An additional 7.4% of women in the survey were infertile (3). Assisted reproductive technology (ART), which has been available since 1981, is the leading surgical treatment for couples diagnosed with infertility. Assisted reproductive technology refers to all fertility treatments in which both egg and sperm are handled. The ART includes IVF and related technologies. These procedures involve surgical egg retrieval from the ovaries and laboratory handling of the Received July 9, 2008; revised October 15, 2008; accepted October 17, 2008; published online December 10, 2008.

As mandated by the 1992 Fertility Clinic Success Rate and Certification Act (FCSRCA), the Center for Disease Control (CDC) has monitored and publicly reported the performance of ART, specifically IVF practices, including pregnancies, deliveries, and multiple births. Although for many couples ART offers the only viable opportunity for having children without seeking adoption, finances and transportation proximity have prevented many from accessing these services. Until recently, insurance coverage for ART/infertility services has not been available to couples. In 2005, there were 14 states that mandated partial or complete ART coverage be included in insurance packages (4). The effect of this insurance status has also not been studied in relation to the supply of ART and populations likely to consume such services. In addition, the number and location of providing ART in relation to the distribution of those most likely needing these resources has not been the focus of research to date. The effect of this insurance status has also not been studied in relation to the supply of ART and populations likely to consume such services. The objectives of our study were twofold: [1] describe the spatial disparity of ART based on their location in relation to the male and female populations in their reproductive years, and [2] identify any association between state- 0015-0282/10/$36.00 Fertility and Sterility â Vol. 93, No. 3, February 2010 745 doi:10.1016/j.fertnstert.2008.10.037 Copyright ª2010 American Society for Medicine, Published by Elsevier Inc.
mandated coverage for infertility services and number and location of ART. We hypothesize that higher potential populations in their reproductive years and potential need correlate with higher numbers of ART services. We also hypothesize that rational distribution of infertility care secondary to mandated status should result in the placement of ART in proximity to populations in their reproductive years. FIGURE 1 Diagrammatic representation of service areas for assisted reproductive technology (ART) (60 minutes driving distance from each ART center) and methodology to define population served by in and out-of-state ART center service areas. MATERIALS AND METHODS Databases The 2000 US Census estimates by sex and age groups for the reproductive years (women 20 44 years and men 20 49 years) and defined as the study populations, were calculated from block group and county level (aggregated from census block groups). The ART registered with the Society for Assisted Technology (SART) in 2005 were retrieved from the website www.sart. org. Street network and speed limit data from ESRI/Geographic Data Technologies (now TeleAtlas) was used. Analytical Tools Geographic Information System (GIS) software ArcGIS 9.2 and Network Analyst Extension of ArcGIS 9.1 by Environmental System Research Institute () was used to map. Sixty-minute travel distances from were calculated using US highways and major roads Environmental System Research Institute /TeleAtlas (http://www.teleatlas. com). The software programs MS Access and Excel were used to compile data tables. Analysis Methods s with partial or complete mandated insurance coverage for ART services in 2005 were identified and stratified versus nonmandated states. The male and female study populations and the total male and female state population (all ages) were calculated from the 2000 Census data and tabulated for each state. All the ART included in the 2005 SART database were located geographically based on their full street addresses. ArcGIS 9.2 and Environmental System Research Institute /TeleAtlas street network data were used to process the addresses and calculate coordinates of the points representing the locations of the ART. Some manual process was involved to locate approximately 15% of the addresses. The US Census data were used to calculate and describe study populations per ART center within each state. Driving distance within 60 minutes from each ART center was calculated exclusive of the three ART located in Puerto Rico, due to inadequate road mapping. Driving distance was calculated using data of street networks and speed limits for all the road segments that could be reached within a 60-minute travel time from the exact address of the ART. All the road segments reached from one ART center Nangia. Access to ART in the United s. Fertil Steril 2010. were then generalized into an area, which defined an ART service area. This step used the Network Analyst extension (module) of ArcGIS 9.1. Service areas were overlaid on top of census block groups. Census block groups touched by the ART service areas were considered as being served by these ART. These populations were aggregated for each state, thereby determining the total populations served by ART within a state. The proportion of each state the reproductive years ART services within a 60-minute driving distance was calculated. In addition, the proportion of a state s population served by in- and out-of-state ART was determined (Fig. 1). The female study population per state was stratified by age, as permitted by the 2000 Census database: 20; 21; 22 24; 25 29; 30 34; 35 39; and 40 44 years old. Statistical Methods Comparisons of means and medians by mandated status were performed using the t-test and Wilcoxon rank sum test (Stata 10.0, College Station, TX). RESULTS The SART database for 2005 identified 390 ART in the United s and its territories. The 60-minute service areas were calculated for 387. Three ART located in Puerto Rico were excluded from analyses due to this territory s inadequate road maps. In 2005, 14 states had partial or complete state-mandated insurance coverage for ART 746 Nangia et al. Access to ART in the United s Vol. 93, No. 3, February 2010

services. California had the greatest number of ART (n ¼ 49) among states with mandated insurance, whereas Florida had the most (n ¼ 25) among states without mandated coverage. Three states had no ART Alaska (nonmandated), Wyoming (nonmandated), and Montana (mandated). The median number of ART was higher, albeit not significantly, among mandated (n ¼ 8) versus nonmandated (n ¼ 4) states (P¼0.10). As a percentage of the total state populations, total population in the reproductive years ranged between 38% and 42% (median 40%) for mandated states, with the highest shared by Texas and California and lowest in Montana (Table 1, Appendix 1). Among nonmandated states, the proportion ranged from 38% 45% (median 40%), the highest in District of Columbia and lowest shared by South Dakota, Florida, Pennsylvania, Iowa, and South Dakota. These findings were not affected by the state s gender distribution. The total study population (i.e., men plus women in the reproductive years) per ART center is displayed for each state, and stratified by state-mandated coverage status, in Figure 2. In the majority of the states, the study population ranged between 200,000 and 500,000 per ART center, with the median population not significantly different between states with mandated versus nonmandated coverage (P¼0.31). The highest study population density was seen in Kentucky with more than 1.5 million men and women in their reproductive years served per in-state ART center. The lowest density was found in the District of Columbia with 65,000 per center. Neither of the states has mandated insurance coverage for ART. Service Areas Figure 3 shows ART by state, as well as total population density of the study population. s within 60- minute driving distance from each ART center are overlaid. The ART appear well distributed in areas of highest population density, with the greatest disparity in the Midwest states and areas of the Northwest. s without an ART center included Montana, Wyoming, Alaska, most of North Dakota, Nebraska, South Dakota, Kentucky, West Virginia, Nevada, Idaho, and Oregon. Table 2 and Appendix 2 list ART coverage for male and female study populations, stratified by mandated insurance status. The most underserved states, defined as %25% of the total study population of a state within 60 minutes of any ART center, include Alaska, Montana, Wyoming, and West Virginia. Other poorly served states include North and South Dakota with 28% and 36%, respectively. The most overserved states, defined as R95% of the total study group of a state within 60 minutes of any ART center include Connecticut, Massachusetts, New Jersey, Rhode Island, and District of Columbia. All these overserved states, except the District of Columbia, had mandated insurance coverage for infertility.

Each state is colorcoded by insurance coverage status for ART to show clustering of populations served. Nangia. Access to ART in the United s. Fertil Steril 2010. Another method of assessing overserved and underserved study populations was to identify the percentage of the population communally/jointly served by in- state ART service areas. This analysis identified that the Northeast of the United s had the most overserved population with 66% 100% of a state study population jointly served. Median total study population within any ART center service area was higher among states with mandated (2,227,330) versus nonmandated (797,781) insurance coverage (P¼.03). Similarly, the median total study population within a 60-minute driving distance of its own state ART was higher in mandated states (2,245,220) versus nonmandated states (777,556) (P<.025). Stratification of female study to age groups revealed that the highest percentage of older women in the reproductive years (35 39 and 40 44 years) as a proportion of the state female study population (20 44 years) was found in northern New England (New Hampshire, Vermont, and Maine), Arkansas and Montana with 23% 25% of the female study each of these age groups. The youngest female study population stratification was seen in Utah and the District of Columbia. Little variability was seen in the proportion of each age group as a function of the overall female population (i.e., women of all ages) for each state. The female study population served was studied in terms of the 60-minute service areas and also analyzed by the 748 Nangia et al. Access to ART in the United s Vol. 93, No. 3, February 2010

The most women served in the 22 24, 25 29, and 30 34 year age groups were found in the District of Columbia with the age groups representing 14%, 22%, and 20%, respectively, of the overall women in the reproductive years for that location/state. The highest proportion of female the 35 39 and 40 44 year age groups within an ART service area was found in Connecticut, with these age groups each accounting for 24% of the overall female study population for that state. Figure 4 shows wide variability in the percentage of state female the reproductive years (22-44 years) living within 60-minutes of any ART service area. The distribution shows the spread between 70-100% for the majority of the states. states had a statistically higher percentage of potential women living in proximity to ART relative to non-mandated states (90 vs. 71%, P¼0.01). DISCUSSION In this cross-sectional study, we found wide variability in the allocation of ART in relationship to populations likely needing those services. Median numbers of ART were higher among states with some form of mandated coverage. ART were located adjacent to a larger study population among mandated states. states had a higher percentage of potential women living within 60-minutes of an ART center relative to non-mandated states. ART has been used to treat patients with infertility in the United s since 1981. The SART, an organization of ART providers affiliated with the American Society for Medicine (ASRM), has been collecting data and publishing annual reports of pregnancy success rates from IVF for fertility clinics in the United s and Canada since 1989. Since 1995, as a result of the FCSRCA, the CDC has worked in consultation with SART and ASRM to report ART success rates publicly (5). These data undoubtedly are helpful to couples needing these services. However, these aggregate and center-specific data do not reveal potential regional and national disparity in services as a function of their location. Although the relationship between mandated ART insurance status and socioeconomic, educational, and racial discrepancies have been described (6 10), the number and location of ART in relation to the population density/the potential population who may need access to these resources has not been the focus of research to date. Of note, the number of ART needed to service a reproductive population is unknown. Several studies have been performed to investigate travel burden on populations ranging from travel time to general medical and dental care to access to family planning Fertility and Sterility â 749

These analyses afford investigators to begin quantifying the geographic burden of health care services, defined as travel time from a patient s residence to the nearest health care service facility. Researchers and health policy experts may then begin having educated discussions regarding allocation of increasingly sparse health care services. The definition used to determine an ART service area was chosen to represent a practical situation for access to care for patients. Patients undergoing these services are often required to travel to their center for a variety of monitoring studies. For example, couples will need monitoring during ART treatment, access to andrology and cryopreservation resources. They will also have to travel to the ART center for egg retrieval and embryology services. Rationalization of Study and Methodology The number of ART listed by the CDC does not correlate exactly with that listed by SART. The CDC in 2005 listed 422, but SART listed 390. The reason for this discrepancy is related to the standards followed in defining reporting. The ART either report directly to the CDC, to the CDC through SART, and finally those that do not report data to anyone. In 2005, SART was responsible for reporting 94% of ART cycles in the United s to the CDC. We opted to use the SART database due to the strict criteria required to report services (i.e., center identification) and outcome results from IVF. This choice afforded us the ability to determine access to providing full embryology services and not just outpatient office settings. We did not include any satellite clinics of listed ART, unless listed separately by SART. Although the National Survey of Family Growth (NSFG) survey defined the reproductive age in women to start at 15 years, for purposes of ART many will not consider womens for treatment until 20 21 years of age. The upper age limit for women of 44 years was chosen as reproductive ability with egg stimulation for ART/IVF has shown no success (0%) beyond the 44th year (15). For men, we chose the upper age of reproductive ability as 49 years of age as the chromosomal risk in men may double after the age of 50 years, although effect on fecundity success is far from clear (16). The NSFG survey in 2002 reviewed fatherhood for men 15 44 years, albeit the indication for this age range was arbitrary and perhaps based on onset of sexual intercourse. This survey of nearly 5,000 men showed that 15% of men had their first child at less than the age of 20 years, 64% between the ages of 20 and29 years, with 21% after the age of 30 years (3). Location of ART Centers in Relation to Potential s We hypothesized that an association exists between highdensity populations and numbers of ART. Analysis of the study population distribution in the United s (Fig. 1) showed a focus of ART in most states, with these residing in or approximate to large cities. Some large cities abut more than one state. Accordingly, we defined the ART service area to include populations residing within the 60 minutes driving distance, both those living in and outside of the ART center s state (Table 2). In this regard, we are able to document overserved and underserved states, as well as populations jointly/mutually both states. The northeast of the United s had a relative high concentration of ART service, perhaps related to a combination of the following factors: [1] a higher number of states with mandated coverage in this region, and [2] relatively large number of metropolitan cities. Three states (Montana, Wyoming, and Alaska) had no ART services, suggesting a lack of fair and equitable allocation of these resources to some populations in the United s. Due to the age-dependent effect of ART success, we stratified our findings by age according to census data (Table 3). The age of 44 years is a significant physiological milestone from an ART reproductive standpoint, with zero success rates reported with ART (15). Such age-stratified analyses may provide insight to the planning and reallocation of ART services as it relates to a changing age demographic across the United s. In the present study, Maine, New Hampshire, and Vermont, had nearly 50% of their female the reproductive (35 44) years. By the year 2010 many states will witness a significant decrease in their populations in their reproductive years. Therefore the usage of ART services will Fertility and Sterility â 753

In 2003, Fisher published a study of regional variations in Medicare spending. In 2000, for example, per capita Medicare spending was $10,550 in Manhattan, but only $4,823 in Portland, Oregon. Despite such a disparity, they found that neither the quality of care nor patients satisfaction with it was related to costs (18, 19). These findings suggest that greater access and use of expensive health care services does not always equate with increased quality. It remains to be seen whether regions with high ART utilization have greater fertility successes, measured not only as total number of cycles, but number of cycles per pregnancy, percentage of cycles resulting in live births, and percentage of live births having multiple infants. Nangia. Access to ART in the United s. Fertil Steril 2010. be impacted, a finding further supported by the CDC ART report from 2005 that 60% of women using ART services were R35 years (5). Influence of Status on ART Centers From a strictly rational standpoint, mandated infertility care status should result in less population per ART center (or per ART service area) as strive to serve the population that has immediate/less restrictive access to this service. To partially address the impact of mandated ART status, we performed a comparison of one state with mandated state coverage for ART, New Jersey, with Georgia and North Carolina, two states having comparable study population sizes. In this example, New Jersey had 81,458 potential residents in the reproductive years per ART center, whereas the nonmandated states on average had 141,780. Whether this is due to an increased number of ART in New Jersey as a result of mandated coverage is debatable. However, it appears that the size of the study population did not dictate the number of ART (19 in New Jersey vs. 7 in Georgia and 9 in North Carolina). Rather, the supply of ART services appears to be insensitive to mandated coverage and thus dictated by some other factor. Based on a more specific and practical parameter, percentage of female study population served by an ART center was higher in mandated (90%) than in nonmandated (71%) states (P<.01). Does More Access to ART Centers Lead to Improvements in Quality? Fisher (17) and colleagues from the Dartmouth Institute for Health Policy and Practice have revealed twofold variability Limitations A relative limitation of this study is our definition of reproductive age, which differs from that used by the CDC. The scope of this article was focused on access to care for women most likely using ART. We chose to consider women from the age of 20 years and not younger because most ART center set guidelines for the youngest age they will treat and also younger patients are more likely to wait longer than a year to seek help if unable to get pregnant. The reproductive age for men was arbitrary but based on literature that shows that genetic risks increase significantly in men more than 50 years of age (16). The authors do acknowledge that men are still in their reproductive years both less than 20 years and more than the age of 50 years, but because the start and end of reproductive years are not well defined for men unlike women, a cutoff had to be applied. The analysis may potentially underestimate the population overall and the underserved. A second limitation is our choice of ART. We relied on a list managed by SART. Thirty-two not in SART still reported findings to the CDC directly in 2005 and may not follow the similar reporting or operational standards as SART. In addition, not all infertility services for ART are provided by ART. As such, our study may underestimate the services available to couples using ARTrelated services in 2005. Finally, we used the 2000 US Census to determine the number and age distribution of the state populations but used 2005 SART data. populations do not appear to be very different in the 2004 US Census projects relative to the 2000 data. Accordingly, we herein used the 2000 Census data. In conclusion, the current study showed that location of ART in the United s appear aligned with populations in their reproductive years. However, significant overserved and underserved areas do exist. Although allocation of mandated status of infertility services did not always result in equitable allocation of ART, mandated status did result, however, in a greater proportion of potentially fertile women living within 60 minutes of an ART center. The impact of this variability in ART services is unknown. It remains to be seen whether greater access to ART results in 754 Nangia et al. Access to ART in the United s Vol. 93, No. 3, February 2010
