Regulatory approval time for hormonal contraception in Canada, the United States and the United Kingdom, 2000-2015: a retrospective data analysis

Emergency contraception subsidy in Canada: a comparative policy analysis

BACKGROUND

In Canada, cost prohibits access to emergency contraception (EC) which may assist to prevent unintended pregnancy. The drug, ulipristal acetate (UPA-EC), is more clinically effective and cost-effective than the prior standard levonorgestrel (LNG-EC). We analyzed provincial EC subsidization policies and examined underlying decision-making processes.

METHODS

We undertook documentary analysis of provincial EC subsidization policies in publicly available drug formularies. We conducted semi-structured interviews with key informants to explore the processes underlying current policies.

RESULTS

Quebec is the only province to subsidize UPA-EC, whilst all ten provinces subsidize LNG-EC. As such, provincial EC subsidization policies do not align with the latest UPA-EC evidence. Interviews revealed that evidence was valued in the policymaking process and formulary decisions were made through interdisciplinary consensus.

CONCLUSIONS

We identify a gap between EC subsidization policies and the latest evidence. Institutional structures affect policies reflecting evolving evidence. Increasing interdisciplinary mechanisms may encourage evidence-based policies.

Induced abortion according to immigrants' birthplace: a population-based cohort study

BACKGROUND

Most abortions occur due to unintended pregnancy. Unintended pregnancies are linked to poor health outcomes. Canada receives immigrants from countries with disparate sexual and reproductive health contexts which may influence abortion rates post-migration. We examined the association between abortion and region of birth and birth order among Canadian immigrants.

METHODS

We conducted a population-based person-years (PY) cohort study in Ontario, Canada using administrative immigration (1991-2012) and health care data (1991-2013). Associations between induced abortion and an immigrant's region of birth were estimated using poisson regression. Rate ratios were adjusted for age, landing year, education, neighborhood income quintile and refugee status and stratified by birth order within regions.

RESULTS

Immigrants born in almost all world regions (N = 846,444) were 2-5 times more likely to have an induced abortion vs. those born in the US/Northern & Western Europe/Australia & New Zealand (0.92 per 100 PY, 95% CI 0.89-0.95). Caribbean (Adjusted Rate Ratio [ARR] = 4.71, 95% CI 4.55-4.87), West/Middle/East African (ARR = 3.38, 95% CI 3.26-3.50) and South American (ARR = 3.20, 95% CI 3.09-3.32) immigrants were most likely to have an abortion. Most immigrants were less likely to have an abortion after vs. prior to their 1st birth, except South Asian immigrants (RR = 1.60, 95% CI 1.54-1.66; RR = 2.23, 95% CI 2.12-2.36 for 2nd and 3rd vs 1st birth, respectively). Secondary analyses included further stratifying regional models by year, age, education, income quintile and refugee status.

CONCLUSIONS

Induced abortion varies considerably by both region of birth and birth order among immigrants in Ontario.

Reasons for hormonal contraceptive use in a cohort of African-American women living in the Detroit area

OBJECTIVES

To characterize reasons for hormonal contraceptive (HC) use in 1,455 African-American women, aged 23-35 years.

STUDY DESIGN

The community-based cohort members were recruited from the Detroit, Michigan area in 2010-2012. HC history was collected via telephone interview.

RESULTS

Seven percent reported HC use exclusively for non-contraceptive purposes, and 49% reported non-contraceptive reasons in addition to contraception. Non-contraceptive reasons were reported for all HC types, but were most common for combined oral contraceptives. Primary reasons were for irregular cycles, heavy bleeding, and pain.

CONCLUSIONS

In this large cohort of Black women, HC use to treat menstrual problems was common.

IMPLICATIONS

HCs were commonly used for both pregnancy prevention and management of menstrual symptoms, but some women used HCs exclusively for menstrual symptom relief. The importance for women of non-contraceptive reasons for HC use may not be adequately recognized, and published data on Black women's reasons for HC use remain limited.

Trends and determinants of postabortion contraception use in a Canadian retrospective cohort

OBJECTIVES

We aim to describe demographic trends associated with postabortion contraceptive choice, characteristics of intrauterine device (IUD) users and relation to subsequent abortion.

STUDY DESIGN

Our retrospective chart review study included all patients obtaining an abortion from 2003 to 2010 at the primary service provider in the Interior Health Region of British Columbia, tracking each patient for 5 years to detect subsequent abortion. We used descriptive statistics to analyze demographic trends and logistic regression to examine determinants of choosing an IUD and likelihood of subsequent abortion per contraceptive method.

RESULTS

Our study cohort included 5206 patients, 1247 (24.0%) of whom chose an IUD. Patients increased IUD use from 10.14% to 45.74% of the cohort over the study period. Mean age of those choosing an IUD significantly decreased over the study period [30.9±7.3 years in 2003 to 26.2±6.5 years in 2010 (p<.001)]. In multivariable analysis, factors associated with choosing an IUD postabortion were prior delivery [aOR=2.77 (95% CI 2.40-3.20)] and being older than 20 years [20-29 years: AOR=1.87 (1.51-2.32); or 30+ years: AOR=1.96 (1.54-2.50)]. Patients choosing an IUD were less likely to have a subsequent abortion compared to those selecting oral contraceptives [aOR=1.96 (95% CI 1.54-2.52)] or depomedroxyprogesterone acetate [aOR=1.84 (95% CI 1.36-2.49)].

CONCLUSIONS

We found an increasing trend of choosing an IUD after an abortion in our population, especially among youth. Patients who chose an IUD postabortion were less likely to have a subsequent abortion over the next 5 years.

IMPLICATIONS

An important strategy for reducing subsequent abortion is to ensure that those seeking abortion have accurate information on the comparative effectiveness of postabortion contraception methods. Educational efforts, alongside removal of cost and other barriers, will contribute to the prevention of subsequent abortion and improve equitable access to IUDs among the population.

Exploring young mothers' experiences with postpartum contraception in Ottawa: results from a multimethods qualitative study

OBJECTIVES

Postpartum contraception plays a significant role in reducing subsequent pregnancy. However, young mothers in Ottawa, the capital of Canada, face various barriers when trying to access contraception after delivery. Through this project, we aimed to explore these barriers and understand the decision-making processes of young mothers surrounding postpartum contraception.

STUDY DESIGN

We conducted 10 semistructured in-depth interviews with young mothers living in Ottawa who had experienced a subsequent pregnancy within 24months of their first childbirth. In addition, we interviewed 10 key informants who work with teenage mothers. We audio-recorded and transcribed all interviews and analyzed them using inductive and deductive techniques. We used ATLAS.ti software to manage our data.

RESULTS

Both young mothers and key informants report that teen mothers in Ottawa often do not use postpartum contraception or inconsistently use their chosen contraceptive method. Many factors, including cost, personal beliefs, personal priorities and knowledge, influence young mothers' decision making surrounding contraception.

CONCLUSIONS

Our study suggests that when young mothers do not use postpartum contraception, the reasons are complex; for some, this is a choice, and for others, this is the result of systems-level, service delivery and information barriers. Supporting policies to ensure that a full range of contraceptive methods are available and affordable and developing educational programs in Ottawa that are sex-positive and nonjudgmental appear warranted.

IMPLICATIONS

Ensuring that a full method mix, including contraceptive implants, is available to and affordable for young mothers in Ottawa could meet significant needs. Addressing existing systems-level, service delivery and information barriers through supporting evidence-based policies and sex-positive and nonjudgmental educational programs appears warranted.
