Association of Travel Distance to Nearest Abortion Facility With Rates of Abortion.

ABSTRACT:

Importance

Travel distance to abortion services varies widely in the US. Some evidence shows travel distance affects use of abortion care, but there is no national analysis of how abortion rate changes with travel distance.

Objective

To examine the association between travel distance to the nearest abortion care facility and the abortion rate and to model the effect of reduced travel distance.

Design, setting, and participants

This cross-sectional geographic analysis used 2015 data on abortions by county of residence from 1948 counties in 27 states. Abortion rates were modeled using a spatial Poisson model adjusted for age, race/ethnicity, marital status, educational attainment, household poverty, nativity, and state abortion policies. Abortion rates for 3107 counties in the 48 contiguous states that were home to 62.5 million female residents of reproductive age (15-44 years) and changes under travel distance scenarios, including integration into primary care (<30 miles) and availability of telemedicine care (<5 miles), were estimated. Data were collected from April 2018 to October 2019 and analyzed from December 2019 to July 2020.

Exposures

Median travel distance by car to the nearest abortion facility.

Main outcomes and measures

US county abortion rate per 1000 female residents of reproductive age.

Results

Among the 1948 counties included in the analysis, greater travel distances were associated with lower abortion rates in a dose-response manner. Compared with a median travel distance of less than 5 miles (median rate, 21.1 [range, 1.2-63.6] per 1000 female residents of reproductive age), distances of 5 to 15 miles (median rate, 12.2 [range, 0.5-23.4] per 1000 female residents of reproductive age; adjusted coefficient, -0.05 [95% CI, -0.07 to -0.03]) and 120 miles or more (median rate, 3.9 [range, 0-12.9] per 1000 female residents of reproductive age; coefficient, -0.73 [95% CI, -0.80 to -0.65]) were associated with lower rates. In a model of 3107 counties with 62.5 million female residents of reproductive age, 696 760 abortions were estimated (mean rate, 11.1 [range, 1.0-45.5] per 1000 female residents of reproductive age). If abortion were integrated into primary care, an additional 18 190 abortions (mean rate, 11.4 [range, 1.1-45.5] per 1000 female residents of reproductive age) were estimated. If telemedicine were widely available, an additional 70 920 abortions were estimated (mean rate, 12.3 [range, 1.4-45.5] per 1000 female residents of reproductive age).

Conclusions and relevance

These findings suggest that greater travel distances to abortion services are associated with lower abortion rates. The results indicate which geographic areas have insufficient access to abortion care. Modeling suggests that integrating abortion into primary care or making medication abortion care available by telemedicine may decrease unmet need.

Project description:BackgroundDespite important progress, the burden of under-5 mortality remains unacceptably high, with an estimated 5.3 million deaths in 2018. Lack of access to health care is a major risk factor for under-5 mortality, and distance to health care facilities has been shown to be associated with less access to care in multiple contexts, but few such studies have used a counterfactual approach to produce causal estimates.MethodsWe combined retrospective reports on 18,714 births between 1980 and 1998 from the 2000 Malawi Demographic and Health Survey with a 1998 health facility census that includes the date of construction for each facility, including 335 maternity or maternity/dispensary facilities built in rural areas between 1980 and 1998. We estimated associations between distance to nearest health facility and (i) under-5 mortality, using Cox proportional hazards models, and (ii) maternal health care utilization (antenatal visits prior to delivery, place of delivery, receiving skilled assistance during delivery, and receiving a check-up following delivery), using linear probability models. We also estimated the causal effect of reducing the distance to nearest facility on those outcomes, using a two-way fixed effects approach.FindingsWe found that greater distance was associated with higher mortality (hazard ratio 1.007 for one additional kilometer [95%CI 1.001 to 1.014]) and lower health care utilization (for one additional kilometer: 1.2 percentage point (pp) increase in homebirth [95%CI 0.8 to 1.5]; 0.8 pp. decrease in at least three antenatal visits [95% CI - 1.4 to - 0.2]; 1.2 pp. decrease in skilled assistance during delivery [95%CI - 1.6 to - 0.8]). However, we found no effects of a decrease in distance to the nearest health facility on the hazard of death before age 5 years, nor on antenatal visits prior to delivery, place of delivery, or receiving skilled assistance during delivery. We also found that reductions in distance decrease the probability that a woman receives a check-up following delivery (2.4 pp. decrease for a 1 km decrease [95%CI 0.004 to 0.044]).ConclusionReducing under-5 mortality and increasing utilization of care in rural Malawi and similar settings may require more than the construction of new health infrastructure. Importantly, the effects estimated here likely depend on the quality of health care, the availability of transportation, the demand for health services, and the underlying causes of mortality, among other factors.

Project description:Background Firefighter first responders dispatched in parallel with emergency medical services ( EMS ) personnel for out-of-hospital cardiac arrests ( OHCA ) can provide early defibrillation to improve survival. We examined whether survival following first responder defibrillation differed according to driving distance from nearest fire station to OHCA site. Methods and Results From the CARES (Cardiac Arrest Registry to Enhance Survival) registry, we identified non- EMS witnessed OHCA s of presumed cardiac cause from 2010 to 2014 in Durham, Mecklenburg, and Wake counties, North Carolina. We used logistic regression to estimate the association between calculated driving distances (≤1, 1-1.5, 1.5-2, and >2 miles) and survival to hospital discharge following first responder defibrillation compared with defibrillation by EMS personnel. In total, 5020 OHCA s were included in the study. First responders more often applied the first automated external defibrillators at the shortest distances (≤1 mile) versus longest distances (>2 miles) (53.4% versus 46.6%, respectively, P<0.001). When compared with EMS defibrillation, first responder defibrillation within 1 mile and 1 to 1.5 miles of the nearest fire station was associated with increased survival to hospital discharge (odds ratio 2.01 [95% confidence interval 1.46-2.78] and odds ratio 1.61 [95% confidence interval 1.10-2.35], respectively). However, at the longest distances (1.5-2.0 and >2.0 miles), survival following first responder defibrillation did not differ from EMS defibrillation (odds ratio 0.77 [95% confidence interval 0.48-1.21] and odds ratio 0.97 [95% confidence interval 0.67-1.41], respectively). Conclusions Shorter driving distance from nearest fire station to OHCA location was associated with improved survival following defibrillation by first responders. These results suggest that the location of first responder units should be considered when organizing prehospital systems of OHCA care.

Project description:Abortion has been legal for multiple indications in Ghana since 1985, and efforts have been made to expand the availability of safe abortion care in the years since. However clandestine, and potentially unsafe, abortions remain common, suggesting numerous barriers to access persist; one possible barrier is poor knowledge of the abortion law among those working in health facilities. Our study aimed to identify levels of legal knowledge among health facility staff across Ghana. Data for this paper are drawn from a nationally representative cross-sectional health facility survey conducted in 2018; our analytic sample includes 340 facilities that provide induced abortion and/or postabortion care (PAC). The survey collected data on provision of abortion and PAC, as well as knowledge of abortion legality and recommendations for reducing unsafe abortion. We used descriptive statistics to examine levels of knowledge and recommendations, and logistic regression to assess associations with individual and facility characteristics. Comprehensive knowledge of the legal indications for abortion was low among health facility staff; just 6% identified all legal indications, and the majority (83%) underestimated the number of conditions under which abortion is legal. Knowledge was higher for more restrictive indications, such as a woman's life being at risk, which was identified by 72% of respondents, than more broadly interpretable indications, such as mental health, identified by 29%. Respondents in facilities providing both induced abortion and PAC had better knowledge of several legal indications than those in facilities providing PAC only. Health facility staff have significant gaps in their knowledge of abortion legality. Knowledge of the law among this population is highly important for ensuring that abortion care is made available to the fullest extent of the law. Efforts are needed to improve knowledge of the law among providers and facility staff, particularly for indications with broad interpretability.

Project description:BackgroundIn the United States, abortion access is often more limited for people who live in states with few abortion facilities and restrictive abortion legislation. Pregnant people seeking an abortion thus often travel to access care.MethodsWe calculated state-specific abortion rate (number of abortions per thousand women ages 15 to 44) and percentage of patients leaving for abortion care using CDC 2017 Abortion Surveillance data, the Guttmacher Institute's Abortion Provider Census and Pregnancies, Births and Abortions in the United States report, and US Census data. We categorized percent leaving by abortion policy landscape using the Guttmacher Institute's classification of state abortion laws, and by facility density (number of abortion facilities per million women ages 15 to 44), calculated using Census and Guttmacher data. We ran correlational tests between each of our variables (percent leaving, facility density, and policy environment), as well as between percent leaving and facility density within policy environment.FindingsIn 2017, an average of 8% of US patients left their state of residence for abortion care. Percent leaving varied widely by state: 74% left Wyoming, 57% left South Carolina, and 56% left Missouri, while 13 states had fewer than 4% of patients leaving. States with more restrictive laws averaged 12% of patients leaving, while states with middle ground or supportive laws averaged 10% and 3% leaving, respectively. Pairwise correlations between percent leaving, facility density, and policy score were all statistically significant, though correlations between percent leaving and facility density within policy environment were not.InterpretationMany patients travel across state lines for abortion care. While patients may leave for a range of reasons, restrictive state-level abortion policy and facility scarcity are associated with patients leaving their state of residence.FundingThis study was supported by a philanthropic foundation that makes grants anonymously.
