Often, this dependence raises concerns about the long-term sustainability, cost-effectiveness, and cultural appropriateness of programs and services. The focus of this review is to summarize and critically appraise evidence regarding both the capacity of refugee and/or internally displaced women residing in camps to provide health services to other women and children in these camps and the effectiveness of such services. Anecdotal evidence suggests that with adequate training, proper supervision, and support, refugee and/or internally displaced women are able to provide basic health services to other women, children and families in camps while avoiding the challenge of ensuring cultural appropriateness and sustainability that are often associated with transient expatriate personnel.</p><p>A refugee is defined as someone who has fled his or her country of nationality to find protection from war or from persecution based on race, religion, nationality, membership of a specific political party and/or political opinion (<xref rid="CIT0001" ref-type="bibr">1</xref>, <xref rid="CIT0002" ref-type="bibr">2</xref>). ‘Unlike refugees, IDPs have not crossed an international border to find sanctuary, but have remained inside their home countries. As such, IDPs are legally under the protection of their own government, even if that government was the cause of their flight’ (2, p. 1). Also included in the definition of IDPs are civilians who are made homeless by natural disasters (<xref rid="CIT0003" ref-type="bibr">3</xref>). At the end of 2011, the United Nations High Commission for Refugees (UNHCR) reported that they were providing services for an estimated 26.4 million people worldwide who have been displaced because of conflict or persecution (<xref rid="CIT0003" ref-type="bibr">3</xref>). Of this number, an estimated 10.4 million were refugees and 15.6 million were IDPs (<xref rid="CIT0003" ref-type="bibr">3</xref>). In addition, UNCHR estimates that nearly half of the population of refugees and IDPs were females (<xref rid="CIT0003" ref-type="bibr">3</xref>). Globally, sub-Saharan Africa is disproportionately affected by conflicts and emergencies that have resulted in large numbers of refugees and IDPs (34% of the global total) (<xref rid="CIT0004" ref-type="bibr">4</xref>). Political, religious, and ethnic disputes are significant factors contributing to these high numbers. For example, the genocide in Rwanda resulted in 1.7 million refugees; the conflicts in Liberia 750,000, and the Somalia conflict, 450,000 (<xref rid="CIT0005" ref-type="bibr">5</xref>).</p><p>As the world continues to experience increases in conflicts and emergencies, health workers and international health agencies are confronted with the challenge of protecting the health of displaced populations. Women, infants, and children are often severely affected, not by the direct effects of weapons, but by displacement, gender-based violence, preventable illness, malnutrition, and inadequate sexual and reproductive health services (<xref rid="CIT0006" ref-type="bibr">6</xref>). Women and children are at increased risk for poor health when community resources and networks that serve as their safety nets are disrupted. Sexual violence and abuse are also of particular concern for women and girls (<xref rid="CIT0007" ref-type="bibr">7</xref>–<xref rid="CIT0010" ref-type="bibr">10</xref>).</p><sec id="S0002"><title>Why it is important to do this review</title><p>As available evidence shows, major health challenges that often confront refugee and internally displaced women, children, adolescents and families include: 1) limited access to health services, 2) increased predisposition to sexual and reproductive health risks, 3) under-nutrition, and 4) chronic disruption of services. Although several international initiatives have sought to unite aid agencies that respond to the needs of refugees and IDPs (<xref rid="CIT0011" ref-type="bibr">11</xref>), attempts to empower displaced women in camps to take control over, and improve their own health have been limited. With the escalation of conflicts and emergencies globally, gaps in access to essential health services for women and children in camps continue to occur (<xref rid="CIT0012" ref-type="bibr">12</xref>–<xref rid="CIT0014" ref-type="bibr">14</xref>). With the flight of local health workers, the burden of health services typically rests on just a few foreign aid workers, severely limiting service coverage (<xref rid="CIT0015" ref-type="bibr">15</xref>, <xref rid="CIT0016" ref-type="bibr">16</xref>). This problem calls for a paradigm shift in efforts to address the maternal and child-health needs of refugees and IDPs in camps using available local human resources. Over the years, a number of intervention studies have been conducted in which refugee and/or internally displaced women residing in camps were provided with targeted training in specific basic health services related to maternal, newborn, and child-health services to other women and families in their camps, and later deployed to apply the resultant knowledge and skills. Anecdotal evidence suggests that such training and deployment have public health benefits but few reviews have articulated this evidence. This review therefore, is an effort to address this gap in knowledge.</p></sec><sec sec-type="methods" id="S0003"><title>Methods</title><sec id="S0003-S20001"><title>Search strategy and selection criteria</title><p>The following electronic databases were searched from inception to June 30, 2014: PsycINFO, PubMed, Web of Science, CINAHL, Sociological Abstracts, Embase, and Internet (Google and Google Scholar). The search was not restricted by publication status or language. The following search terms were first created for a search in PubMed, and later adapted for the other databases: (‘Community Health Workers’ OR ‘Health Personnel’ OR ‘Volunteers’ OR ‘Health Services’ OR ‘Delivery of Health Care’ OR volunteer OR ‘health worker’ OR ‘health auxiliary’ OR ‘relief work’ OR ‘relief worker’ OR ‘health care delivery’ OR peer); (‘Refugees’ [Mesh] OR ‘refugee camps’ OR ‘internally displaced’); #1 AND #2. We hand-searched reference lists of identified articles, and contacted bilateral agencies and non-governmental organizations (NGOs) whose programs may include interventions for refugees and/or IDPs with a request for information on previous and ongoing studies. Three reviewers (JE, JG, and YL) coordinated the literature searches.</p></sec><sec id="S0003-S20002"><title>Inclusion/exclusion criteria</title><p>1) Types of study: We attempted to identify studies that assessed the capacity of lay women who were refugees or internally displaced, to provide basic health services to maternal and child populations (women, children, and adolescents) in camps for refugees and/or IDPs and the outcomes of such services. We excluded repeated reports, books, studies that provided general discussion about training of non-refugee community health workers, and descriptive papers on refugees and IDPs in camp settings. Studies that assessed the effectiveness of services provided by trained local or expatriate health workers such nurses, doctors, and other skilled medical and allied health professionals. Given the ethical and logistical challenges of conducting randomized controlled trials under camp settings and the dearth of empirical evidence on the subject, we sought to include a wide variety of studies in order to capture as much available data as possible. Thus, we included cohort studies, cross-sectional studies, controlled pre-and-post studies, controlled post-test studies, and pre-posttest studies that included an evaluation component. 2) Study population: Females aged 15 years and over, who were residing in camps for refuges/IDPs, and who were involved in providing basic health services to women, children adolescents and families in camps settings or who had received training to provide such services. 3) Outcome measures: a) Changes in health-related knowledge, attitudes, and practices of refugee or internally displaced lay women as a result of training aimed at equipping them to provide basic health services to women, children, adolescents and families in camps; b) changes in health outcomes of women, children, adolescents and families in camps as a result of services provided by trained lay women who were refugees or internally displaced (e.g. changed sexual risk behaviors; fewer unintended pregnancies; increased immunization uptake/coverage; increased uptake of ante-natal and post-natal care and nutrition services; reduced maternal and/or child under-nutrition; increased uptake and use of insecticide-treated bed nets; less frequent malaria cases among women, children, and adolescents; and fewer diarrhea episodes).

This study-conducted by the Reproductive Health Group (RHG) across the Forest Region of Guinea-used refugee nurses and midwives, and trained lay refugee women as facilitators who provided sexual and reproductive health education to reproductive-aged Liberian and Sierra Leonean refugees living in 48 camps. Through a multistage stratified cluster sampling, 445 men and 444 women were surveyed to assess whether receiving sexual and reproductive health information from lay health workers, trained nurses/midwives, or friends was associated with better knowledge of sexually transmitted infections (STIs) and better health seeking behaviors related to sexual and reproductive health. Overall, participants reported a high prevalence of STIs in the last 12 months (30% women; 24% men). A marked gap in sexual health knowledge was also reported, as only 25% correctly named key symptoms of STIs. Respondents who cited either the refugee nurses/midwives and lay health facilitators as their information source of sexual and reproductive health information demonstrated greater knowledge of STIs.

This study used a controlled post-test community-based study to assess the effects of health education intervention provided by lay refugee health workers on child malaria treatment-seeking practices among rural refugee mothers of children aged 6 months to 5 years. Refugee health workers were trained to provide health education using local beliefs, terminology, and disease concepts via one-to-one discussions, informal group meetings, and disseminated informational materials. Eight refugee villages were selected; four were assigned to an intervention and four to a control arm.

The objective of this study was to assess the effects of peer-refugee health education on maternal health knowledge, attitudes, behaviors, and maternal health outcomes. Using a refugee self-help model, refugee women mobilized other women who had expertise as nurses, and midwives, as well as other local lay refugee women, as health educators to provide education, make referrals, and distribute contraceptives to women in refugee communities. Local refugees were recruited and trained to interview same-sex respondents. A cross-sectional survey on sexual and reproductive health attitudes related to family planning was administered to 889 participants (445 men; 444 women). Contraceptive use was shown to be markedly higher in areas served by refugee health workers than in the refugees’ under-served countries of origin or host countries (17% vs. 3.9% and 4.1%, respectively).</p><p><bold>Howard et al.

Participants were considered ‘exposed’ to this education if they had previously participated in a peer-refugee facilitated drama group or received information on family planning by a peer-refugee health worker.

This study used a pre- and post-test design to assess the impact of training and deploying internally displaced villagers to conduct malaria control interventions among IDPs. Staff from the local health department trained internally displaced villagers who lived in the malaria program's target communities and were familiar with other village members. These village health workers were trained in malaria diagnosis, treatment, and vector control. Specifically, they were trained to perform a comprehensive set of malaria interventions, including promoting of the use of long-lasting malaria nets, detecting of early signs and symptoms of malaria, and providing treatment in an active civil conflict area.

In target communities, lay health workers and traditional birth attendants were trained in basic emergency obstetric care, blood transfusion, antenatal care, and family planning. A post-intervention survey was conducted to assess the effects of the intervention on accessing ante- and post-natal care, skilled attendants at births, and family planning services. Results showed that, following intervention, use of insecticide-treated mosquito nets increased, as did use of modern contraceptives. Births attended by those trained to deliver elements of emergency care increased about 10-fold.</p><p><bold>Rijken et al. [Thai-Myanmar Border]</bold>(<xref rid="CIT0025" ref-type="bibr">25</xref>). This study used a pre- and post-test design to assess the effects of a 3-month practical and theoretical training for lay refugee health workers aimed at equipping them with skills in conducting obstetric ultrasound imaging based on World Health Organization guidelines and British Medical Ultrasound Society recommendations. Post-test assessments measured intra-observer and inter-observer agreement of fetal biometry in 349 pregnant women measured by trained displaced health workers compared to those conducted by an expatriate physician. Measurements by refugee health workers showed high levels of agreement with those of the physician, demonstrating that locally trained health workers from refugee camps could adequately conduct obstetric ultrasound imaging.</p><p><bold>Tanaka et al.

The majority of the sampled community members and TRCS health staff affirmed the positive contribution of HIT to refugee health (89.2 and 100%, respectively). Seventy-nine percent of the sampled refugee community members reported that they learned about illness prevention from the HIT. Also, HIT was the education method most highly rated by the refugee community, both for learning how to prevent illnesses (56.3%) and for learning how to treat mild diarrhea (50.0%). The role played by the HIT as a liaison between the refugee community and health services was recognized by 85.2% of the refugees surveyed; refugee community members who did not know a HIT member demonstrated less positive health seeking behaviors than those who knew one or more HIT members (<xref rid="CIT0022" ref-type="bibr">22</xref>).</p><p><bold>Woodward et al. [Guinea]</bold> (<xref rid="CIT0021" ref-type="bibr">21</xref>). This was a cross-sectional study designed to assess the association between exposure to refugee peer education and improved HIV knowledge, attitudes, or practice outcomes among refugees in Guinea. Data were collected from 889 reproductive-age men and women in 23 camps in the Forest Region of Guinea, and exposure to peer refugee led education was analyzed and compared with HIV outcomes using logistic regression odds ratios. The results of these analyses showed that exposure to peer refugee health education was associated with awareness of HIV/AIDS and reduced misconceptions about the disease. Overall, participants who were exposed to peer refugee education had more than twice the odds of reporting having made HIV-avoidant behavioral changes than those who were unexposed (72% versus 58%; adjusted OR 2.49, 95% CI 1.52–4.08) (<xref rid="CIT0021" ref-type="bibr">21</xref>).</p></sec></sec><sec id="S0009"><title>Critical appraisal of data on impact of use of lay refugee health workers</title><p>As shown in <xref ref-type="table" rid="T0001">Table 1</xref>, all of the included studies demonstrated some positive impact on population health outcomes as a result of training and deployment of lay refugee/IDP health workers in camps. The reported effects included improvements in knowledge, attitudes, and practices related to various sexual, reproductive and other maternal and child health issues. Specific examples included increased knowledge about the symptoms and prevention of STIs, improved treatment-seeking and protective behavior adopted by those experiencing STI symptoms, and uptake of family planning services. Other reported changes included improvements in child fever and malaria treatment-seeking behaviors, and improved access to reproductive health information. One study, which assessed the effect of peer refugee health education on maternal health knowledge, attitudes, behaviors and maternal health outcomes (<xref rid="CIT0019" ref-type="bibr">19</xref>), did not demonstrate marked reduction in unintended pregnancies among refugee women. For the purpose of this review, study quality assessment revealed that all included studies were of poor quality. For example, in five of the included studies (<xref rid="CIT0012" ref-type="bibr">12</xref>, <xref rid="CIT0018" ref-type="bibr">18</xref>–<xref rid="CIT0021" ref-type="bibr">21</xref>)
, the analysis did not separate impact of interventions delivered by refugee nurses and midwives from those delivered by trained refugee women who served as lay health workers. Cropley (<xref rid="CIT0023" ref-type="bibr">23</xref>) used a post-test only design. The lack of comparability of intervention and control communities at baseline raises concerns about internal validity (<xref rid="CIT0029" ref-type="bibr">29</xref>), i.e. the approximate truth of inferences regarding causal relationships. Although the study by Lee et al. (<xref rid="CIT0026" ref-type="bibr">26</xref>) demonstrated the ability of trained displaced villages to contribute to significant expansion of malaria treatment and prevention services, it did not assess the quality or outcomes of services provided by the trained lay refugee villagers. Minden (<xref rid="CIT0027" ref-type="bibr">27</xref>), Mullany et al. (<xref rid="CIT0024" ref-type="bibr">24</xref>), and Rijken et al. (<xref rid="CIT0025" ref-type="bibr">25</xref>) used the before-and-after design in assessing the effectiveness of trained lay refugee community health workers and traditional birth attendants in providing basic reproductive health services, and in diagnosing and treating common illnesses. Before-and-after design is relatively cheap to implement and useful in addressing potential ethical concerns that may be associated with randomized studies or prospective cohort designs. However, the lack of a comparison group limits the degree to which observed health outcomes can be attributed to services provided by lay refugee workers. Outcome measures assessed by all studies (<xref rid="CIT0012" ref-type="bibr">12</xref>, <xref rid="CIT0018" ref-type="bibr">18</xref>–<xref rid="CIT0027" ref-type="bibr">27</xref>)
were based on self-reports, which are known to be subject to the effects of social desirability (<xref rid="CIT0030" ref-type="bibr">30</xref>). More importantly, none of the studies assessed the relationship between the degree of exposure to interventions provided by lay refugee workers and health outcomes.</p></sec><sec sec-type="discussion" id="S0010"><title>Discussion</title><p>Globally, a shortage of human resources for the health sector is widely acknowledged as a key barrier against the provision of essential health services (<xref rid="CIT0031" ref-type="bibr">31</xref>). The burden of health workforce shortage is more acute in low-income countries, especially those experiencing conflicts and emergencies, when the few available health workers are forced to flee, health infrastructures are destroyed, and resources for the health sector are diverted to other uses. Available evidence shows that community health workers have the potential to be part of the solution to the human resource crisis that is affecting many countries (<xref rid="CIT0032" ref-type="bibr">32</xref>, <xref rid="CIT0033" ref-type="bibr">33</xref>), and scaling up training and deployment of community health workers is one of the strategies identified in the Kampala Declaration and the Agenda for Global Action (<xref rid="CIT0034" ref-type="bibr">34</xref>). A systematic review conducted by the Global Health Workforce Alliance and the United States Agency for International Development (USAID) to elucidate the effectiveness of community health workers concluded that adequate training, integration, and supervision of community health workers has the potential to contribute to an equitable and cost-effective scale-up of service coverage, while leading to tangible improvements in health outcomes (<xref rid="CIT0028" ref-type="bibr">28</xref>).</p><p>In light of evidence regarding the effectiveness of lay workers in population health improvement, there is a need to re-evaluate how camps for refugees and IDPs are organized and the way services are provided for women and children who reside in camps. With a five-fold increase in emergencies caused by natural disasters and/or conflicts over the past decade, it has become increasingly difficult for international relief agencies to keep pace (<xref rid="CIT0035" ref-type="bibr">35</xref>). Camps are resource-limited settings. As such, available resources and services become quickly depleted with time. There is a need to train and effectively deploy lay refugees and IDPs in order to sustain access to health basic health services. Lay-refugee and internally displaced women who reside in camps have life experiences that are similar to those of other women in the camps. They also have valuable health-related cultural knowledge that expatriates may not have (<xref rid="CIT0017" ref-type="bibr">17</xref>, <xref rid="CIT0031" ref-type="bibr">31</xref>). Thus, there is the perception that, if trained and adequately supported, they can be well-positioned to provide culturally appropriate support that is better targeted to the needs of women and children in the camps. Similar to the village health-worker and promotora approaches that have been shown to be beneficial in helping to meet the healthcare needs of women and children in resource-poor settings globally (<xref rid="CIT0036" ref-type="bibr">36</xref>), lay refugees and IDPs who reside in camps could potentially help ease reliance on foreign health professionals, improve access and coverage, and empower women to enhance their health and the health of their children and families. Whereas anecdotal evidence suggests that training and deployment of lay refugees and IDPs have public health benefits, no reviews have sought to assess and critically appraise the evidence base of this intervention to facilitate policy recommendations. Therefore, in order to address this gap in knowledge, we conducted a systematic review and critical appraisal of available data.</p><p>An exhaustive search of the literature yielded only 10 studies that attempted to assess the role of lay refugees and IDPs in reproductive health service provision in camps. All of the included studies reported some positive impact association with training and deployment of lay refugee/IDP health workers in camps. The reported effects ranged from improvements in knowledge, attitudes, and health seeking behavior; an increased efficacy to treat mild diarrhea; a capacity to conduct obstetric ultrasound imaging; an ability to diagnose and treat minor conditions (including malaria and STIs); to an increased uptake of family planning services. While these findings are important, the current body of evidence is weak, and there remains a paucity of high quality evaluation studies of the impact of using trained lay refugees and IDPs to provide health services to camp dwellers.</p></sec><sec id="S0011"><title>Limitations</title><p>As noted earlier, this review included studies that used a wide variety of designs (cross-sectional, post-test only, and pre- and post-test) that have significant inherent limitations, especially regarding internal validity. For example, cross-sectional studies measure exposure and health outcomes simultaneously. Thus, it is difficult to determine the direction of the observed associations. Post-test only studies lack baseline comparability of intervention and control communities; before-and-after studies lack appropriate comparison groups. Although many international health agencies are involved in emergency response activities globally, none was able to provide information on evaluated studies of interventions that involved the use of refugees and/or IDPs to provide maternal and child health services in camps. This raises concerns about the value placed on evidence-based practice in international emergency response activities. However, it should be understood that camps are resource-limited settings. Under emergency situations, where the primary health objective is to ensure safety and access to basic services for refugees and IDPs, it may be difficult to commit limited resources to planning and implementing rigorous evaluation studies. It may also be difficult to employ such rigorous evaluation designs as the randomized controlled trial (RCT) due to ethical reasons. Thus, notwithstanding these challenges, it is important to note that time, money, and efforts expended on activities of questionable impact have opportunity costs. To the extent that is reasonably practicable, interventions that train and deploy lay refugees and IDPs as healthcare workers should be rigorously evaluated in order justify resource.</p></sec><sec id="S0012"><title>Implications for research and practice</title><p>To further elucidate the strength of the association between training and deployment of lay refugee/IDP health workers and the quality of basic health services in camps, there is a need for high quality follow-up studies conducted in different geographical regions of the world and among individuals of diverse racial/ethnic cultural backgrounds. Currently, available evidence reflects an urgent need for adopting a more evidence-based practice approach. While it is true that the most important objective when organizing such training interventions as described above, is to promote population health, efforts should also be made where possible to strengthen the mechanisms for collecting the best evidence to advocate for more training programs and to facilitate the replication of best practices in other settings. Studies that assess the quality of services provided by lay refugee/IDP health workers in camps are needed, as are studies that demonstrate the effects of such hard outcome measures as reduced morbidity and mortality or positive measures of health and wellness, rather than simply changes in knowledge and attitudes.</p></sec><sec id="S0013"><title>Conclusion</title><p>While available evidence suggests a positive impact of training and deployment of lay refugee/IDP health workers to provide basic maternal health services in camps, the body of evidence is weak and calls for a re-examination of current practices. It is important that every intervention includes a strong evaluation component to better elucidate the extent to which changes in outcomes can be attributed to interventions provided by lay refugee/IDP health workers in camps.</p></sec></body><back><sec id="S0014"><title>Conflict of interest and funding</title><p>The authors have not received any funding or benefits from industry or
