15 Sep 2022: The PLOS ONE Staff (2022) Correction: Interventions facilitating access to perinatal care for migrant women without medical insurance: A scoping review protocol. PLOS ONE 17(9): e0274983. https://doi.org/10.1371/journal.pone.0274983 View correction
Inadequate pregnancy monitoring for pregnant migrant women without medical insurance (PMWMI) exposes them to severe complications during childbirth and consequences for the health of their child (e.g. preterm delivery, low birth weight, etc.). This scoping review aims to identify existing interventions globally to improve access to perinatal care for PMWMI. It will also highlight the strengths, weaknesses as well as the costs of these interventions.
Materials and methods
The methodological framework developed by Arksey & O’Malley (2005) will be used. An electronic search of studies from 2000 to 2021, published in French or English, will be conducted in 12 databases. Publication in Websites of non-governmental organizations working on migrant women without medical insurance issues will be also searched. All articles related to perinatal follow-up and care of PMWMIs, regardless of design, will be included. Editorial comments will be excluded. Outcomes of interest will focus on the impacts, strengths, weaknesses, and cost of interventions. Selection of articles and data extraction will be done by two independent researchers following the Tricco et al. (2018) reporting guide. Finally, a deliberative workshop with experts will allow to identify the most promising and appropriate interventions that can facilitate access to perinatal services by PMWMIs in the Quebec province of Canada.

Although the phenomenon, known as the ‘healthy immigrant effect’, has been repeatedly reported [1, 2], in many countries , migrant women face inadequate pregnancy follow-up  resulting in more miscarriages, fetal growth problems, premature birth and high perinatal mortality . Those without any medical insurance are more vulnerable than other migrants [6, 7]. They often consult a healthcare provider very late during pregnancy  and frequently have severe complications during childbirth . They also experience a higher number of emergency caesarean sections, which can be traumatic for the mother and the unborn child . These women also have a high prevalence of postpartum depression , parasitic  and other infectious diseases (Hepatitis B; Hepatitis C; HIV) / AIDS). The fact they experienced challenges in accessing perinatal care , constitutes a double burden. This issue among pregnant migrant women without medical insurance (PMWMI) is a complex subject. Several interventions exist to address this including; (i) earlier care (ii) regular care; (iii) culturally appropriate; (iv) geographically accessible; (v) multidisciplinary; (vi) integrated with other community services / resources and at lower cost [12, 13].
We have not identified a scoping or systematic review of these interventions which would allow a better understanding of access to perinatal care for PMWMIs. It is therefore opportune to carry out some in order to list the interventions promoting the access of PMWMI women to perinatal care. As mentioned by Arksey and O’Malley (2005) and Levac (2010), a scoping review [14, 15] of these interventions will allow us to synthesize them, to know their strengths, their weaknesses and their costs. Thus, it will be possible to implement appropriate interventions depending on the context in order to facilitate access to perinatal care for PMWMIs. Knowing the costs would help inform decision-makers about the financial benefits of investing in setting up these interventions. This scoping review will fill the literature gap. It aims to identify interventions that have been employed to improve access to perinatal care for PMWMI. It will also highlight the strengths, weaknesses as well as the costs of these interventions.
Materials and methods
The methodological framework developed by Arksey & O’Malley (2005)  and taken up by other authors [15, 16] will be used. This framework highlights six steps necessary for a good Scoping Review: (i) definition of the research question; (ii) identification of relevant studies; (iii) selection of studies; (iv) data extraction; (v) analysis and aggregation of results; and, (vi) consultation exercise.
The purpose of this scoping review project is to identify interventions (practices and policies) that support PMWMIs’ access to perinatal care. It will answer the two following questions:
- What are the interventions that facilitate access to perinatal care for PMWMI women?
- What are their impacts on perinatal health, what are their strengths, weaknesses and what is the cost of implementation?
Inclusion and exclusion criteria will be based on Population, Interventions, Comparators and Design and Outcomes or Anticipated Outcomes (PICO), summarized in Table 1.
Migrants are not a homogeneous population. According to the glossary of the International Organization for Migration, the term "migrant" refers to "a person who has voluntarily moved or is forced to move, whether within a country or across an international border, temporarily or permanently, and for a variety of reasons, in order to improve his or her material and social conditions, his or her future prospects or those of his or her family" . In addition to coming from different countries and cultures, a distinction is made between migrants: (i) in a regular situation whose entry and stay in the host country are in accordance with the applicable law; (ii) and, in an irregular situation contravening the regulations of the host country by entering it irregularly or remaining there beyond the validity of the residence permit [17, 18]. As part of this review, internal displaced as well as refugees and asylum seekers without health insurance will also be considered. This review will include articles that focus on migrant women 12 years and older without health insurance who are either pregnant, in labor, or postpartum. Articles that focus on the perinatal period of migrant women without health insurance will be considered.
They include the care provided to uninsured migrants during the perinatal period as well as the policies and practices implemented to promote their access to this care. The perinatal period adopted for this study is broader than the World Health Organization definition  and extends from the beginning of pregnancy to the first months of life of the newborn . Care during pregnancy including prenatal education, labor, delivery and postpartum, as presented in the Médecin du Monde (MdM) reference framework  will therefore be considered. Details of prenatal care (during pregnancy follow-up), immediate obstetric and neonatal care (during labor, delivery, and within two hours of delivery), postpartum care (within 42 days of delivery), and newborn care (up to 28 days after birth) are presented in Table 2.
Comparator and design (C).
All empirical scientific studies, regardless of design, in French or English of any high, medium or low income country- (see S1 Appendix which presents the complete list of countries as listed by the World Bank in 2021)  will be accepted. Media articles, editorial comments, as well as studies focusing only on the profile of PMWMIs will be excluded. No comparison is foreseen.
Data sources and study identification
This scoping review has been registered in Research Registry (6864; https://www.researchregistry.com/browse-the-registry#home/). The recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews (PRISMA-ScR)  (see S1 Checklist) will be followed in carrying out this review. The specifications of the elements relating to the construction of the Flow diagram will be explicitly mentioned. Articles will be selected via: (i) electronic bibliographic databases CINHAL, Web of Science, Medline-Ovid, Pubmed, Embase, Cochrane Library, Scopus, ScienceDirect, Hinari, Lilacs, Cairn and Banque de Données Santé Publique (BDSP); (ii) reference lists; (iii) key journals in the field of immigration (Revue Migrations Forcées; Migrations Société); and (iv) Websites of non-governmental organizations (Médecin du monde, Médecin sans Frontières (MSF), United Nations High Commissioner for Refugees (UNHCR). A working meeting between the co-researchers of this project, including an experienced librarian (CS), has already allowed the definition of the search strategy presented in Table 3. This strategy was developed using descriptors or thesauri with the logical operators "AND" and "OR" to identify relevant studies published between 2000 and 2021 in French or English. The year 2000 was a landmark turning point for the entire world with the formulation of the eight Millennium Development Goals (MDGs), where emphasis was put in poverty and hunger reduction (MDG 1) the promotion of gender equality and empower of women (MDG 3) and among other child mortality reduction (MDG 4) . The selected articles will be exported to Rayyan  via EndNote.
A librarian of the Université du Québec en Outaouais (CS) will be responsible for applying the search strategy and extracting articles from the databases in order to prepare the EndNote bibliographic database. This database will then be cleaned and duplicates removed before exporting the articles to Rayyan platform. The selection of articles will be based on the inclusion and exclusion criteria defined by the PICO and will be done in two stages. At the first stage of selection, an article will be eligible if, through its title and abstract, it is possible to clearly identify the PICO in relation to those selected for the study. To do this, two researchers will independently examine the title and the abstract of the articles identified according to an algorithm built with predetermined eligibility criteria (Fig 1) and will justify in writing the eligibility of the articles. An article will be retained if both declare it eligible. Any disagreement will be resolved either by discussion, or by another co-researcher who will review the title and abstract and give a verdict. The article will be retained if two of these three people declare it eligible. This is an iterative process in which the researchers involved in the project will meet at the beginning, middle and end of the abstract review phase to discuss challenges and uncertainties related to the selection of studies in order to refine the research strategy if necessary. At the final stage, eligible articles will be read in their entirety. For any question regarding the content of an article, the authors will be contacted for further clarification. To harmonize the selection process, the selection of 10% of the articles will be discussed by all researchers beforehand.
We developed a data extraction grid (S2 Appendix) that is an adaptation of the grid used by Stirling Cameron et al.  in their scoping review on access to and use of sexual and reproductive health services by refugee and asylum-seeking women in high-income countries. This grid, built in an excel spreadsheet, will allow the extraction of the following information: name of authors; year of publication; country; title and abstract; study design; study population; sample size; interventions (antenatal care, immediate obstetric and neonatal care, postpartum care, newborn care, policies and practices in favor of this care); impact; strengths; weaknesses; and cost of implementation of these interventions. Because the data extraction process is iterative, the data extraction grid will be updated by the researchers as the data extraction progresses. Two researchers will independently extract data from the first five studies, and then meet to harmonize the data extraction (consistent with the research question and purpose of the study).
The data analysis will be done in four steps: 1) organizing the studies into logical categories related to the targeted objectives; 2) reporting the results by intended objectives; 3) examining their meaning; 4) comparing the interventions implemented and their outcomes in regard to the setting (high-, medium- or low-income country), and 5) discussing the implications for future research, clinical practice, and health policy. In addition, a narrative summary will describe how the results are related to the research questions. The results that will be obtained, i.e., the interventions in favor of access to perinatal care by PMWMIs, the impact, strengths, weaknesses, and cost of implementation of these interventions, will be submitted for expert review as described in the following section.
This process is based on a participatory approach  in order to deepen the results  and to constructively contextualize  the identified interventions with expert researchers and practitioners whose work focuses on access to sexual and reproductive health services for vulnerable persons and immigrant women. In addition to the researchers, 15 experts who will take part in this workshop will have the following profiles: (i) academics (three) working in the field of the access to perinatal care for vulnerable populations; (ii) experts (three) of a non-governmental organization (NGO) that provide perinatal care to vulnerable populations; (iii) experts (three) of community-based organizations that provide perinatal care to PMWMI; (iv) experts (three) who work or have worked in a municipality’s immigration team; (v) experts (three) of the public health system and who are familiar with the issues of access to perinatal services for PMWMI. Experts will be identified and invited by email to participate in a workshop. Upon their agreement, written informed consent will be obtained prior to the start of the workshop. Due to the context of the COVID-19 pandemic, the deliberative workshop will be virtual via a Zoom platform. It will address the following questions: (i) What interventions would promote access to perinatal services for PMWMI in the Quebec context? (ii) Which are the most promising and affordable (efficient) for this population in Quebec? (iii) What recommendations (for policy makers, community organizations, NGOs) could be made based on the interventions identified? The deliberative workshop will take approximately three hours. It will be conducted in four stages: (1) The first (30 minutes) will be the presentation of the results of the scoping review by the research team; (2) The second (45 minutes) will be group work, four groups of 5–6 people. Each group will discuss in depth the questions posed and summarize them; (3) The third (60 minutes) will consist of a plenary presentation of the conclusions of the group work; (4) Finally, the research team will synthesize the recommendations and present them in plenary for final validation (30 minutes).
This project has been accepted by the Research Ethics Committee of the Université du Québec en Outaouais. Written informed consent will be required from the experts who will be joining the consultation session.
Our project aims to identify interventions that support access to perinatal care for pregnant migrant women without medical insurance by answering broad research questions and providing an overview of the literature. Thus, a scoping review described above is more appropriate for this study than the more common systematic review. Also, by using this approach we can determine whether it is appropriate to undertake a full systematic review. Another strength of this approach is the fact that it allows, through the consultation of experts, to deepen and adapt the results obtained .
Although the results of this scoping review should be interpreted with caution as only French or English studies will be considered and their quality is not assessed. In addition, a scoping review focuses on the mapping and scope of studies, rather than the depth of information; it describes what is known rather than providing new knowledge. These limitations are inherent in this method and do not affect the results that will be obtained. At the end of the expert consultation, the most promising and appropriate interventions will be identified to facilitate access to perinatal services by PMWMIs in the Quebec province of Canada. In addition to a scientific article, an advocacy and policy brief will also be drafted and submitted to policy makers in charge of immigration and migrant health to facilitate the consideration and integration of the results obtained.
