Rapid health evaluation in migrant peoples in transit through Darien, Panama: protocol for a multimethod qualitative and quantitative study.

BACKGROUND: The world is currently unprepared to deal with the drastic increase in global migration. There is an urgent need to develop programs to protect the well-being and health of migrant peoples. Increased population movement is already evident throughout the Americas as exemplified by the rising number of migrant peoples who pass through the Darien neotropical moist broadleaf forest along the border region between Panama and Colombia. The transit of migrant peoples through this area has an increase in the last years. In 2021, an average of 9400 people entered the region per month compared with 2000-3500 people monthly in 2019. Along this trail, there is no access to health care, food provision, potable water, or housing. To date, much of what is known about health needs and barriers to health care within this population is based on journalistic reports and anecdotes. There is a need for a comprehensive approach to assess the health care needs of migrant peoples in transit. This study aims to describe demographic characteristics, mental and physical health status and needs, and experiences of host communities, and to identify opportunities to improve health care provision to migrant peoples in transit in Panama. STUDY DESIGN AND METHODS: This multimethod study will include qualitative (n = 70) and quantitative (n = 520) components. The qualitative component includes interviews with migrant peoples in transit, national and international nongovernmental organizations and agencies based in Panama. The quantitative component is a rapid epidemiological study which includes a questionnaire and four clinical screenings: mental health, sexual and reproductive health, general and tropical medicine, and nutrition.
CONCLUSION: This study will contribute to a better understanding of the health status and needs of migrant peoples in transit through the region. Findings will be used to allocate resources and provide targeted health care interventions for migrant peoples in transit through Darien, Panama.

Introduction

Currently, there are 281 million international migrant peoples worldwide, which is three times greater than the number of migrant peoples estimated in 1970. In addition, the number of forcibly displaced people worldwide has risen dramatically in the past decade. The world is currently unprepared to deal with population movement of this scale, and there is an urgent need to develop programs to protect the well-being and health of migrant peoples. A dramatic increase in population movement is evident through the Americas, where migrant peoples from Africa, Asia, South America, and the Caribbean travel through South and Central America en route to North America. Although other portions of the route may involve travel by air, train, or bus, migrants who arrive in South America headed north must travel on foot through the Darien National Forest along the border region between Panama and Colombia.

The Darien Forest (DF), commonly called the ‘Darien Gap’, is a roadless, dense, 106-km long neotropical moist broadleaf forest that interrupts the Pan-American Highway and serves as a natural barrier between Colombia and Panama. The crossing – through what is known to be ‘the most dangerous and inhospitable’ jungle in the world – is a treacherous journey, often taking between 7 and 14 days depending on the route taken, the amount of food carried, and travel group members’ abilities.

Migrant peoples who travel this route have no access to potable water or food and must face deadly river crossings, scorching high temperatures, and poisonous animals. Some indigenous communities situated along the dense forest’s outskirts provide a temporary resting place for migrant peoples in transit. Drug traffickers also share the trails, and people who have made the journey have commonly reported human trafficking, smuggling, and violence. Moreover, from May to September 2021, 180 cases of rape were reported to Doctors Without Borders.

The National Border Police (SENAFRONT) guides migrant peoples who emerge from the Gap to ‘Migrant Reception Stations’ (MRS), organized by the National Migrant Services. All individuals who enter by foot into Panama, with very few exceptions, pass through these MRS. These posts are part of the international ‘controlled flow’ of migrant peoples in a coordinated effort between the United States and Panama, where biometric measurements are taken of all individuals entering the country to screen for terrorism and keep a document trail of individuals.[5,6] Time spent at the MRS depends on several factors including the individual’s nationality, health needs, and demographics. Citizens of some countries are allowed to pass quickly, while others may need to wait months for their migration process in Panama. Individuals from South America and the Caribbean (except Haiti and Cuba) are among those who have nonexpedited processes and these nationals who arrive in Darien must go through lengthy months-long visa processes before continuing. Citizens from other countries often stay in the Darien MRSs for approximately 3–14 days before being transported to another MRS near the Panama–Costa Rica border, where they will remain until initiating their travels north.

From 2015 to 2021, there has been a steady increase in the number of migrant peoples in transit that pass through the DF at the Colombia–Panama border en route to North America.[7-9] Prior to 2020, there were between 2000 and 3000 individuals who crossed into Panama monthly through the DF. These trails have been used for centuries to cross between the two countries; however, from 2016 onward the number of people using this route has increased annually. From January to September 2021, more than 91,000 migrant peoples entered Panama through the DF. This recent increase follows a period early in the COVID-19 pandemic where a large number of people were unable to cross international borders.[8,11] In addition, perceptions of the United States’ changes in immigration policies with the Biden administration has been identified as impacting the number of migrant peoples through these routes. Individuals who make this journey come from different countries (Map 1). According to official records from Panama’s National Migration Service, over 70% are Haitian citizens, 20% Cuban citizens, and the remaining 10% originate from sub-Saharan Africa, Asia, and South America. Furthermore, from 2018, there has been an increase in children, families, and pregnant women entering Panama on foot through the DF.[8,13] Individuals from outside the continent arrive in South America by land or sea, often arriving in Ecuador or Brazil, beginning their journey by land up to the Panama–Colombia border.[7-9]

There is no access to health care along the route through the DF and very limited access to needed health services while in the MRSs. During the DF crossing, migrant peoples are exposed to dangerous elements from the days spent in the tropical forest and people encountered during their route. These elements are coupled with increased prevalence of diseases and health conditions common in their countries of origin prior to beginning their route through Darien. In recent years, Panama’s Ministry of Health (MINSA) and some international organizations have provided resources to begin to address the health needs and offer health care to migrant peoples in transit at the MRS. However, the COVID-19 pandemic has reoriented health care service provision, where health care is focused on SARS-CoV-2 diagnosis and quarantine; however, other services such as general health, sexual health, mental health, reproductive medicine, and fever management have been left aside.[14,15] Pan American Health Organization has recommended in their priority actions a need to strengthen surveillance and monitoring of the prevalence of health conditions through: (1) the development of comprehensive profiles of the health status of migrants, and (2) strengthening of national and decentralized health surveillance systems, especially in the border-transit areas that can capture the health status and needs of migrants. In accordance with these recommendations, this study protocol is intended to be a rapid assessment of migrant peoples’ health status, needs, impact on surrounding communities, and opportunities for improved service provision to this population. Results from the study will inform future health care for migrants in transit in Darien and the region.

Methods

Study design and population

This study will use both qualitative and quantitative cross-sectional methods. We will use qualitative research methods to capture the perspectives and experiences of migrant peoples in transit and stakeholders (Table 1). In addition, we will use qualitative research to learn from the experiences of a variety of stakeholders, including those who provide services, design and allocate resources to programming, and individuals that live in the communities where migrants pass while crossing the DF. Participants within the study’s qualitative component include government health and migration personnel, representatives from international organizations working with migrant populations, community members from surrounding host communities, and migrant peoples.

The qualitative component (Component A) will use purposive sampling and undertake semi-structured interviews, focus groups, and select participant observation to assess health needs and service provision to migrant peoples (Table 2). Qualitative data collection tools (i.e. semi-structured interview guides for each stakeholder group) will be designed to capture data to describe divergent health priorities and available health services, evaluate patient barriers for accessing health services, and document needed resources for improving health care provision according to stakeholder perspectives. Through coding and thematic analysis of interviews, results of the qualitative component will allow our research team to contextualize prevalence data from the quantitative study component. The qualitative component will provide insights from key stakeholder groups, in their own words. Interviews will provide rich descriptions of the migrant experience and health needs of migrants in transit through Darien, as well as challenges to health services provision. We will use this information to prioritize needs and identify targets and strategies for future intervention.

The quantitative component (Component B, Table 1) includes a rapid epidemiological study among migrant peoples in transit. This component will include a self-administered questionnaire, and four clinical screenings: mental health, sexual and reproductive health, general and tropical medicine, and nutrition. Age of inclusion for each subcomponent can be found in Table 2. The self-administered questionnaire (Supplementary material A) includes demographics, migration routes, sexual and reproductive health and behaviors, and self-reported health. This questionnaire was developed from existing instruments (some modified for this population).[17-26] For the clinical laboratory components, participants will be asked to provide a mid-stream urine sample and a peripheral blood sample for laboratory point-of-care screenings for the following infections/conditions: hepatitis A, B, C, and E; Chagas disease; malaria; dengue; chikungunya; HIV; syphilis; and pregnancy (Table 3). Further rapid testing will be applied, according to clinical presentations, as indicated in Table 4. Clinical screening will include a review of the present and past medical history, vital signs, body measurements, and a physical examination. On-site treatment (Table 5) and/or referral to primary, secondary, or tertiary centers will be organized (supplementary material B) according to clinical and laboratory findings.

Sample size calculations

To determine the required sample size for (1) participants aged ⩾18 years, and (2) participants aged <18 years in this cross-sectional, observational study, we used where n is the sample size, Z the confidence statistic, P is expected prevalence and d is the precision. Based on a past survey by the International Migration Organization, we expect 16% of migrant peoples in transit in Panama with gastrointestinal diseases; this prevalence was used for sample size calculation. The sampling frame composed of a total population expected to enter the MRS (2500; 20% of those are <18 years). In total, 120 participants <18 years and 160 participants ⩾18 years will be included. We have a larger planned sample for the questionnaire, as we expect over half of these individuals will consent to filling out the questionnaire but not be willing to participate in the more time-consuming clinical components.

Ethical considerations

This study has approval from the Comité de Bioética de la Investigación del Instituto Conmemorativo Gorgas de Estudios de la Salud (260/CBI/ICGES/21). Participants 18 years and older will be asked to read a study information sheet and sign the informed consent form. Participants 12–17 years will have their guardian read and sign the guardian information sheet and informed consent form, and the participant will be required to read and sign the informed assent form. Participants <12 years will be required to have a guardian read and sign the informed guardian consent form. Participants will not be offered monetary compensation for their participation. However, a small snack (valued at less than $3.00) will be provided. All participants will be given educational sheets that cover the syndromes and infections tested for, and these sheets will be posted publicly at the MRSs. The consent forms, assent forms, questionnaire, and educational materials will be available in Spanish, English, French, Haitian Creole, and Portuguese languages.

Participant selection

In Component A, we will use purposive sampling. Community leaders will be asked to attend focus group interviews, and institutional, national, and organization leaders will share their perspectives through individual semi-structured interviews. A group of migrant peoples will also be selected to participate in individual semi-structured interviews. Select migrants accessing health services may be accompanied to observe their experiences within available health care providers. A total of 70 participant interviews and focus group discussions are anticipated within the qualitative study component, as this number is expected to allow us to reach saturation in capturing stakeholder perspectives and experiences.

In Component B, participants will be included systematically, where groups of 40–50 individuals arrive at the MRS where the sampling will be undertaken. When lined up to be registered with the Migration Service, small invitation cards will be given to every 1:n person from each stratum. The n will be calculated at the start of each day and depends on the number of expected strata to arrive each day, to include between 30 and 50 participants daily. After the person finalizes the migration registration process, they will be asked to join the study group at the respective study tents. Inclusion and exclusion criteria are dependent on the study component, as outlined in Table 2. As potential participants may be at the MRS for an undetermined amount of time, this study will only include participants who do not have a planned exit from the MRS within 8 h.

Data capture

Data capture will differ by study component and methods employed. Component A will include participant observation, semi-structured interviews, and focus groups captured via ethnographic fieldnotes and recorded on a digital recorder. Interviews and focus groups will be conducted in Spanish and, if needed, interviews with migrant persons will be undertaken in English and through real-time interpreters of French, Portuguese, or Haitian Creole. Component B will include a self-administered questionnaire on a tablet using Kobo Toolbox Software (Harvard Humanitarian Initiative, Cambridge, MA) and will be stored on the device under the participant’s code until Wi-Fi is available. Clinical and laboratory information will be inputted into Kobo Toolbox with a separate entry for each participant.

Pharmacological and psychological treatment and referral

On-site treatment by study subcomponent is found in Table 5. If the participant needs to be referred to primary, secondary, or tertiary facilities for further care (Supplementary Table B), this will be organized by the study team and the participant will be transported with no cost to them.

Pharmacological treatment

On-site pharmacological treatment will be given according to the severity of the affectation. A higher level of care will be arranged if needed to on-site or referral to the nearest health center in the town of Meteti or to the secondary and tertiary hospitals, in Chepo and Panama City, respectively. The field clinic where the study is undertaken is rudimentary and will not attend to all needs. Therefore, some cases will be referred to health centers and hospitals where (a) the condition requires further testing or specialized care, or (b) treatment is intravenous or daily injections, as described in Table 5.

Psychiatric care and treatment

Following the Refugee Health Screener-15 item survey (RHS-15) screening and meeting with the psychiatrist, individuals who would like to participate in group-oriented therapy are welcome to attend language-based sessions. In addition, at any time, if the participant seems in distress, presents with acute psychosis or self/heteroaggression, immediate consultation with an on-site psychiatrist will be done. Treatment protocol is summarized in Table 5 according to syndromic presentations.

On-site management of distress

At any time during the study, if a participant is anxious, depressed, or distressed, the ‘Distress Protocol’ will be activated (Supplementary material C). The ‘Violence Protocol’ will be implemented for individuals who report sexual violence during the qualitative component, questionnaire, or clinical exam (Supplementary material D). These are based on the Ministry of Health procedure for sexual violence, rape, incest, and a previously published protocol for children who report violence that has been used in previous studies in Panama and worldwide.[23,29]

Lab and clinical results

The laboratory point-of-care (POC) tests and clinical results will be given to every participant in paper format the day they are included in the studies. All results will be explained to the participants at the time results are offered. The results will also be found in a password-protected location on the Gorgas Memorial Institute for Health Studies’ webpage. Each participant will have access to a secure portal for 1 year, which will house their study results and educational sheets. The portal will be accessible from a phone or computer. The participants’ access information and password will be clipped into their passports.

Data analysis plan

Data analysis will depend on the study component.

For Component A, recordings and fieldnotes will be transcribed; all identifying information will be deleted. The recorded files will be destroyed after the transcription. Transcripts will be coded by MB and AG using NVivo software (QSR International Pty, Melbourne, Australia). Both coders will work independently and codes will be compared, discussed, and discrepancies will be resolved. Transcripts will be saved on an encrypted external hard drive. The data will be analyzed with a thematic analysis method and in an essentialist manner, meaning the participant experiences will be revealed. Transcripts will then be coded at a manifestation level to include the main themes. It is also possible that some codes emerge inductively from the data. This hybrid method of analysis from the data has been previously described and demonstrated to be rigorous. A thematic map will be constructed, revised, and altered based on team discussions; contradictions and negative cases will be identified and presented.

For Component B, descriptive and analytical methods will be used to describe the findings of the quantitative questionnaire, including sociodemographic factors, sexual and reproductive biography, sexual behaviors, nonconsensual sexual relations, self-reported health, family whereabouts, and social well-being. In addition, the prevalence of laboratory and clinical diagnoses will be presented for the sample as a whole, as well as for key subgroups, including men, women, adults, and young persons. Quantitative questionnaire responses will be used to describe the epidemiology of test positivity and diagnoses. Sociodemographic and behavioral variables that are significantly associated with health outcomes of interest in bivariable analyses will be included in multivariable regression models to estimate strength of adjusted associations and test their significance.

Discussion

By 2050, the United Nations (UN) estimates that over 1 billion people could be displaced due to climate change alone.[1,31] Many others are leaving their country of origin for work, family, conflict, persecution, and natural disasters. This increase in population movement is already evident throughout the Americas, especially in Panama, where migrants from different Caribbean regions, South America, Africa, and Asia, travel through South and Central America en route to North America. Unfortunately, the world and Latin America are not prepared to provide medical care for mass migration.

PAHO has highlighted a need to strengthen both health surveillance and the monitoring of existing programs targeted toward migrant peoples in the region. This rapid evaluation of health status and service provision among migrant peoples in transit aims to respond to this evidence gap. Employing a mixed qualitative and quantitative approach, the study will investigate the health status and needs among migrant peoples in transit passing through the Darien MRSs. Currently, individuals with acute illness or emergency health conditions, such as pregnancy, may be transferred to nearby MINSA health centers. However, the occurrence of other health conditions, such as anxiety, post-traumatic stress disorder, depression, genitourinary syndromes, and tropical diseases, as well as mal/under-nutrition, remain largely undetected and ignored; information related to their prevalence among migrant peoples in transit through the region remain widely unknown.

As the demographics of migrants who opt for this perilous route shift, information related to the health needs of this population and opportunities for strengthening service provision at the MRS and regionally for migrant peoples in transit is essential. This study is critical to understand health priorities, especially with infectious and tropical disease, nutrition, mental health, and sexual and reproductive health of those who pass thorough the DF. In addition, findings could be used to optimize scarce resources targeted toward improving the well-being of migrant peoples who pass through this region. Previous research among people in transit in Central America and Mexico has led to recommendations to decriminalize irregular migration; identify and stop human trafficking, particularly of women and children; and expand the number of migrants’ shelters as a way to meet basic needs. Furthermore, studies recommend better coordination and collaboration among governmental and nongovernmental organizations – and across borders – to prevent and control health problems faced by migrant people in transit. Furthermore, researchers recommend improving access to primary health care, including sexually transmitted disease and HIV testing, among this population.[33,34] To ensure that the results of this project inform programs and policies for migrants in transit, results and targeted intervention recommendations that will have emerged from the qualitative and quantitative studies will be presented locally to MINSA and international nongovernmental organizations that focus on service provision to migrant peoples.

Access to health care is a human right – increasing migrant health and health literacy translate into future social engagement, citizenship, and productivity. The overarching goal of this project is to document the health needs of migrant peoples in transit who pass through Panama in order to provide initial surveillance information and recommendations for targeted interventions for this mobile population. To do this, the project will use POC testing and a comprehensive, easily deployable package of health services. Strengthening POC diagnosis and service delivery will be essential to address barriers to quality health care for migrant peoples who frequently have insufficient time to receive provider follow-up and continuity of care. The literature from other contexts of migration indicates that strategies to screen and treat migrant populations for transmissible diseases, including tuberculosis, hepatitis B, hepatitis C, HIV infection, enteric bacteria, and helminths, can be both impactful and cost-effective in the control of infectious disease. Addressing these unmet health needs and improving service provision can help alleviate the incredibly marked inequities migrant peoples have experienced and sustained in their journey.

The challenges to deploy and deliver a point of health care for migrant peoples in transit are enormous – facing barriers including discrimination, violence, communication, and insufficient access to health care.[4,37] Such issues have described a perceived idea of ‘deservingness’ that categorizes patients, particularly migrant peoples, as more or less deserving of access to quality health care. There are few published data on health care needs of migrant peoples in transit through Latin America en route to the United States. Gray literature from UN and other international nongovernmental organizations suggest the greatest health needs include treatment of fever, skin problems, diarrhea and prenatal care. The successful implementation of a health screening protocol like our proposed study may become a platform to scale up in different migratory routes in the Americas and in other regions. Furthermore, the successful conduction of this study may provide crucial information to increase awareness and lead to effective targeted health care services for migrant peoples in transit.

Conclusion

The results of the qualitative and quantitative studies answer the PAHO call to contribute to a better understanding of the health status and health needs of migrant peoples in transit through Panama. It will also serve to strengthen interventions of national and decentralized health and surveillance systems nationally and regionally. Most importantly, the results from this study can be used to develop targeted interventions of health care provision for migrant peoples in transit through the DF and the Americas.
