Describing the safety of abortion at the population level using network-based survey approaches.

BACKGROUND: Despite the negative impact of unsafe abortions on women's health and rights, the degree of abortion safety remains strikingly undocumented for a large share of abortions globally. Data on how women induce abortions (method, setting, provider) are central to the measurement of abortion safety. However, health-facility statistics and direct questioning in population surveys do not yield representative data on abortion care seeking pathways in settings where access to abortion services is highly restricted. Recent developments in survey methodologies to study stigmatized / illegal behaviour and hidden populations rely on the fact that such information circulates within social networks; however, such efforts have yet to give convincing results for unsafe abortions. OBJECTIVE: This article presents the protocol of a study whose purpose is to apply and develop further two network-based methods to contribute to the generation of reliable population-level information on the safety of abortions in contexts where access to legal abortion services is highly restricted. METHODS: This study plans to obtain population-level data on abortion care seeking in two Health and Demographic Surveillance Systems in urban Kenya and rural Burkina Faso by applying two methods: Anonymous Third-Party Reporting (ATPR) (also known as confidantes' method) and Respondent Driven Sampling (RDS). We will conduct a mixed methods formative study to determine whether these network-based approaches are pertinent in the study contexts. The ATPR will be refined notably by incorporating elements of the Network Scale-Up Method (NSUM) to correct or account for certain of its biases (transmission, barrier, social desirability, selection). The RDS will provide reliable alternative estimates of abortion safety if large samples and equilibrium can be reached; an RDS multiplex variant (also including social referents) will be tested. DISCUSSION: This study aims at documenting abortion safety in two local sites using ATPR and RDS. If successful, it will provide data on the safety profiles of abortion seekers across sociodemographic categories in two contrasted settings in sub-Saharan Africa. It will advance the formative research needed to determine whether ATPR and RDS are applicable or not in a given context. It will improve the questionnaire and correcting factors for the ATPR, improve the capacity of RDS to produce quasi-representative data on abortion safety, and advance the validation of both methods.

Representative data on how women induce abortions and their consequences are central to measurements of abortion safety. However, due to the stigmatized nature of abortion, measuring the details of the process is challenging when the latter occur out of the realm of the law and do not result in complications registered in hospital statistics. Hence, there is sparse empirical population-level data on how women terminate their pregnancies in countries where access to abortion services is highly restricted, as well as little data on the side effects and complications associated with the methods they chose and health seeking for these complications. Recent developments in indirect survey methodologies to study stigmatized/illegal behaviour and hidden populations are likely to improve the quality of data collected on abortion safety in restrictive contexts: all are based on the sharing of information on stigmatized practices in social networks. We propose to refine and pilot two such network-based methods to validate their use for collecting (quasi) representative data on abortion safety in large population health surveys. These two approaches are: (i) a modified Anonymous Third-Party Reporting method (ATPR) integrating elements of the Network-Scale-up Method (NSUM) and (ii) Respondent-Driven Sampling (RDS). We will conduct this study in two African Health and Demographic Surveillance Systems (HDSS) sites, one urban (Nairobi, Kenya), and one comprising a town and adjacent villages (Kaya, Burkina Faso).

"I always know she cannot betray me." Disclosure of abortion and methods of abortion used in informal settlements in Nairobi, Kenya.

Despite abortion being stigmatized and legally restricted in Kenya, women still disclose their abortions within their network. Evidence has shown how stigma can influence and regulate individual abortion disclosure decisions and behaviors. This paper seeks to understand why and how women make the decisions to disclose their abortion and the associated methods used. The data are from a qualitative formative study and a respondent-driven sampling survey conducted between 2020 and 2021 in two informal settlements in Nairobi, Kenya. The data were analyzed using a descriptive analysis approach for the quantitative data, and thematic analysis for the qualitative data. Our findings reveal that information sharing about abortion is enclosed in a social dynamic of secrecy. This dynamic contributes to making abortion a secret that respondents decided to share with confidants in 81% of the abortion cases. These confidants include intimate relationships such as trusted friends (62%), followed by female relatives. Information was shared in many cases either to get support (i.e. method to use), or because participants had close ties with the confidants. Regarding the methods used, unidentified pills were the most used regardless of the confidant; followed by traditional methods especially among those who sought help with their mothers/aunts/grandmothers (33%), while Medical Abortion and Manual Vacuum Aspiration were rarely used, mostly by those who confided in friends or sisters/cousins. Our findings show that the disclosure of abortion is a complex process embedded in existing codes regarding the circulation of information on sensitive issues and "help" seeking. Our findings show that the need for information on safe abortion and lack of financial resources frequently empowers them to overcome the fear of stigma and disclose their abortion. However, this often resulted in use of unsafe procedures. The findings suggest the need for strengthening the circulation of information on safe methods within communities, using community champions and intermediaries to increase the likelihood of women being directed through safe methods to enhance their use.
