Health & Justice volume 12, Article number: 39 (2024)
Abstract
Mozambique implemented in 2021 a formative assessment in 22 prisons to identify the operational and logistical needs for the second round of the Biobehavioral Survey (BBS). Barriers and facilitators that could be anticipated in conducting BBS in prisons, in preparation for implementation, was evaluated using semi-structured questionnaires administered to key informants (directors and other kind of managers staff). The data were cleaned and analyzed using Microsoft Excel, and the categorical variables were summarized by means of simple frequencies and percentages. In most prisons the current prison capacity far exceeds the theoretical capacity, 40.9% have a theoretical capacity of ≥ 50 inmates, 81.8% have inmates who exceed their theoretical capacity. In the country half of the prisons receive only male inmates, and only one female, 54.5% of the prisons visited have inmates under 18 years of age, 72.7% of the prisons had a private space available for the survey, the penitentiary establishments have the physical space for study; ensuring the safety of staff within the facilities; involvement of correctional officers and a clinical focal point. However, barriers such as time management due to prison opening hours, prison laws, restrictions, or permits for research may change without notice due to security, lockdowns, riots, or other situations that may hinder the implementation of research. The implementation of successive and regular rounds of BBS in different environments, contexts and populations constitute opportunities for generating information and indicators not always captured by programmatic data and not only as an opportunity for offering and making healthcare available in prison environments that in a routine context, but these populations normally have also not had equal opportunities. Currently, little is known about the implementation of a BBS in a correctional environment and only a few barriers can be anticipated, for Mozambique’s context, these challenges and obstacles can be overcome through clear communication and collaboration with officials at all levels.
Background
It is estimated that at any given time, has nearly eleven million people held in prison settings around the world, and about 668,000 of those are in the sub-Saharan African region (UNAIDS, 2021). At the global level, the prevalence of HIVFootnote 1,TBFootnote 2, hepatitis (B and C), and other STIFootnote 3 are reportedly as ben higher among inmates when compared with the general population (Dianatinasab et al., 2018). Several structural factors inherent to the prison conditions, including overcrowding, human rights violations, lack of access to prevention and treatment services, as well as behavioral factors, such as sexual activity between men (including forced sex), drug use (including injecting drugs), and tattooing or the practices of shaving are all associated with HIV transmission among prisoners.
Although data are very limited, the Sub-Saharan African region has one of the highest HIV prevalence rates among inmates (Azbel et al., 2016a). Penitentiary establishments and other closed settings are one of the most neglected in the regions’ responses to addressing HIV in low- and middle-income countries. The rigid and poor prisons infrastructure sometimes makes it difficult to implement preventive programs against the transmission and spread of the disease. Furthermore, when this population transitions back to the community, they can continue to spread disease to the general population since they did not receive the required treatment while incarcerated (Azbel et al., 2016b).
The sudden outbreak of the COVID-19 pandemic highlighted human rights concerns for people deprived of their liberty such as prisoners. The overcrowded and confined conditions, poorly ventilated infrastructure, unsanitary conditions, as well the justice system and legal representation amplified their susceptibility to high rates of COVID-19 infections and mortality in incarcerated settings (P et al., 2020; Wang et al., 2020).
Due to the “revolving-door” effect, wherein inmates, prison staff, and prison visitors move in and out of the prison, there is great potential for the transmission of diseases to home communities and to other incarceration facilities, thus further contributing to the spread of these communicable pathogens across the population (Meyer et al., 2014, Telisinghe et al., 2016).
Frequent prisoners transfer and the cycle of recidivism can also impede the continuity of care for those undergoing treatment for communicable diseases, particularly for those requiring long-term treatment such as HIV and TB. These disrupted treatment cycles can contribute to increased pathogen resistance at the population level (Biadglegne et al., 2015).
In Mozambique, according the research done by Reformar, it is often reported that the prison health service does not have access to the equipment and medicines needed to provide adequate medical care. The quality of health care that prisoners have access to was generally assessed as inadequate. With regard to inmates with physical disabilities, there is little or no provision made for their needs. These aspects justify the would require further research about availability of health services in the prison’s to help to identify the health needs with the inmate must have must have to reduce and improve morbidity in the penitentiary establishments (REFORMAR, 2018).
The HIV epidemic in the country is a critical public health issue with an estimated HIV of 13.2% among adults over the age of 15, one of the highest in the world (Ministério da Saúde (MISAU) et al., 2015; Semá Baltazar et al., 2021). In order to control the HIV epidemic, Mozambique is working to increase utilization and access to prevention, testing and treatment programs for several key populations for example, female sex workers (FSW), men who have sex with men (MSM) and people who inject drugs (PWID), who are generally at higher risk of HIV infection than the general population. These populations also face a number of legal and social barriers that affect their use and access to health services, as well as increase their vulnerability to HIV. In addition to the populations mentioned above, incarcerated people are equally by the Mozambican government as a key population in the National Strategic Plan on HIV/AIDS (PEN IV, 2015).
The World Health Organization (WHO) defines key populations as population groups that are at greater risk of infection and transmission of HIV, viral hepatitis or STIs, due to various health-conditioning factors (social, legal, structural and other contextual), which increase their vulnerability to HIV, viral hepatitis and STIs, and limit access to health services and social support. At a global level, key populations are sex workers (SW), men who have sex with men (MSM), people who inject drugs (PWD), transgender people (TG) and prisoners.
According to Mozambique’s National Strategic HIV and AIDS Response Plan (2015–2019), the objectives for key populations are to ensure that this may have access to quality, evidence-based health services in order to contribute to an effective response to the HIV epidemic in Mozambique (PEN IV, 2015). In response, the National Program for STI and HIV/AIDS Control developed the National Guidelines for the Integration of HIV/AIDS Prevention, Care and Treatment Services for Key Populations in the Health Sector (PEN IV, 2015). These present a set of ten (10) strategic interventions to address the specific prevention and treatment needs of key populations. At present, the implementation of the comprehensive service pack is focused on FSW and MSM, to the detriment of PWID and prisoners due to logistical issues.
Its is important to refer that initially data on HIV prevalence and associated risk behaviors in Mozambique were obtained through surveys such as the HIV and Syphilis Epidemiological Surveillance Round in Pregnant Women at Antenatal care services, the Demographic and Health Survey, and at the National Survey of Prevalence, Behavioral Risks and Information on HIV and AIDS in Mozambique. These surveys do not provide specific information for key populations at greater risk for HIV such as long-distance truck drivers, Mozambican miners working in South Africa, female sex workers, men who have sex with other men, people who inject drugs, and transgender people. Hence the need to produce additional evidence on indicators related to these groups in the country, necessity clearly expressed in Mozambique’s National Strategic Plan for the Response to HIV and AIDS (PEN IV 2015–2019), which considers it important to conduct representative surveys capable of providing evidence and defining specific actions for these populations. It was in this context and based on the recommendations strategic information for monitoring the response national HIV policy (PEN IV, 2015–2019; PEN V-2021-2025), that BBS were implemented in Mozambique.
Biological and behavioral surveys (BBS) are specific surveys with specific methodologies conducted in key populations, considered difficult to access because of their condition and other peculiar characteristics. These surveys are part of a national biological and behavioral surveillance system capable of monitoring changes in the evolution of the HIV epidemic and other STIs in the key population in the national response. These surveys were implemented in Mozambique for the first time in 2009.
Therefore, in 2013 was carried out the biobehavioral survey with inmates and the results showed, as established in the assumptions that justified the study, it was expected that the results of the HIV, STIs and TB were more than twice the prevalence in the general population, or in prisoners as well as in penitentiary agents. The report indicated that 24% (22.3–25.9) of inmates in Mozambican penitentiary establishments were infected with HIV; 16% (14.5–17.5) were infected with treponema pallidum and 1.5% (0.9-2.0) for the Tuberculosis bacillus. The same indicates that 18.5% (13.6–24.8) of the penitentiary agents of Mozambican penitentiary establishments were infected with HIV and 9.7% (6.0–14) are infected by trepomena pallidum. Nonpenitentiary agents was positive for Tuberculosis bacillus in the year in which the study took place. The report concludes that HIV prevalence among prisoners is high, but lower than expected. The presence of STI symptoms is associated with HIV infection in inmate (Ministry of Justice, 2013). The prevalence of HIV among penitentiary agents is high and very above the prevalence in the general population with men being the most affected (UNODC, 2013).
The Correctional System in Mozambique faces yet numerous difficulties related to infrastructure, allocation of health providers, social, and other services, and the existence of infectious diseases such as HIV and other STIs, TB, malaria, skin diseases, etc. Among the different diseases, communicable disease is the primary problem in the prisons, and transmission can continue when individuals return to their communities. In addition to needing to care for the health and well-being of the inmates, they require special attention because their release and re-integrate back into the community can have repercussions on the dynamics of transmission and his/her reinfection for HIV, Syphilis and others STIs (Augusto et al., 2017; Vaz et al., 1996).
As a way of following up on the surveillance activities for this type of population, the INS in collaboration with partners carried out in 2021 the first round of the BSS in the incarcerated population and penitentiary agents with a view to monitoring the progress achieved by interventions aimed at the prevention of HIV infection, provision of care and treatment services in this population.
This kind of survey in general can advise the Ministries of Health and of Justice and the Constitutional and Religious Affairs to join efforts as a way to create and harmonize policies that promote and improve health in the correctional system. Acting in a more integrated perspective can contribute to the construction of a correctional health system closer relied on human rights and on more equitable access to health in the Correctional Facilities of Mozambique.
Before the implementation of the survey itself, a formative evaluation was carried out in all provinces of the country to identify the operational and logistical needs for carrying out the main phase of the survey in each location, to deepen knowledge about the characteristics of the incarcerated population and correctional officers, as well as to assess the conditions of infrastructure and other specific information related to this study.
This paper was written from this assessment to provide information related to the barriers and facilitators in the implementation of an ethically and scientifically sound BBS survey among the prisoner population in Mozambique, to assist future prevention and treatment efforts.
Methodology
A formative assessment was conducted in 22 penitentiary establishments in 11 provinces using a methodology of systematic probability proportional to size with implicit stratification between May and August 2021. These establishments size was specified as the square root of the penitentiary establishments population and province was used as the stratification variable. The penitentiary establishment were selected if the incarcerated population was (at least 50), the organizational structure had (health center, security conditions, infrastructure conditions to accommodate the survey team, visual and auditive privace) in each establishment. This approach was used to minimize the geographic representation of the selected establishments. All penitentiary establishment stated that they have an updated list containing the number of inmates that might be available if requested in advance for the purpose of random and anonymous recruitment (ensuring confidentiality about the description of the identity of the participants). All penitentiary establishments were chosen in consultation with Correctional Service from the Ministry of Justice.
Study population
The formative assessment was conducted among 22 penitentiary establishments directors, staff and some incarcerated people; they were all over 18 years old. They were identified as key informants since they possessed knowledge of the working mechanisms of each establishment, the characteristics, behaviors, attitudes, and practices of inmates and correctional officers, as well as the type of services existing or not of the penitentiary establishment. All individuals provided written informed consent for the participation responding an in semi-structured questionnaire.
Data collection
A semi-structured questionnaire was developed with questions about the functioning of penitentiary establishments, types of existing assistance services (health, social action, social reintegration, etc.), capacity of inmates, opening hours, among others. The questionnaires were administrated by trained interviewers and data collected using Tablets and open-source ODK platform.
In addition to the data collection carried out with key informants, in-person observations were carried out at each sampled establishment. The observations were done to primarily assess the establishment intake process, confirm the presence of health centers, evaluate the conditions of the health centers, and potential locations amenable to the implementation of the BBS survey and to ensure confidentiality. Before the implementation of the formative assessment, the data collection team members received training, including an overview of the incarcerated population as well as correctional officers, ethical aspects in research involving human beings, vulnerabilities, and standardized operational procedures for data collection. All information captured from the questionnaires and observations were sent to the central server housed at the Data Management Unit of INS in Marracuene Village. The average length of time for each questionnaire administration was between 30 and 45 min. The investigators closely supervised data collection and administered some of the questionnaires.
Data analysis
Descriptive data were cleaned and analyzed using Microsoft Excel, and categorical variables were summarized using simple frequencies and percentages. The open questions were categorized and analyzed thematically.
Assessment results
Formative assessment is a research technique that uses rapid ethnographic assessment methods (quantitative vs. qualitative) that allow identifying the operational and logistical needs for carrying out the main phase of the survey (BBS) in each location, deepening knowledge of the characteristics of the populations -key in the survey locations, identify hotspots, where we can find these populations, approach and recruitment mechanisms and other specific information’s.
In this current study, a total of 22 penitentiary establishment were assessed (two in each province), using a semi-structured questionnaire. The average length of time for each questionnaire administration was between 30 and 45 min per selected participant,
According to the data, in most establishment, the actual prison capacity far exceeds the theoretical capacity. Many establishments (40.9%) have a theoretical capacity of 50–100 inmates and, most of this (81.8%) have inmates that exceed their theoretical capacity.
Half (50%) of the establishments only house male inmates, and only one is specific to female inmates (located in the Maputo City). More than half (54.5%) of 22 establishments visited have inmates under 18 years of age. About three quarters (72.7%) of the establishments had a private space available to conduct the survey (Table 1).
Facilitating factors or study implementation
Coordination and partnership
Several researchers report challenges to get the permission to conduct research with inmates (Fox et al., 2011). We found and identify as facilitators the fact that a close collaboration established with the Ministry of the Interior, which oversees Correctional Department, is essential to successful survey implementation. All required authority figures within the Ministry of the Interior provided their approval and co-signed an authorization letter describing the general methodology, taking into consideration establishment-specific operations and programmers such as operation hours, eating schedule, workouts and others. As the Correctional Department is a hierarchical institution at Ministry of Interior and therefore all approvals must first be granted by the respective Directors.
Most establishment were willing to provide physical spaces – such as meeting rooms, medical care offices, or the atrium – where the team can perform data collection activities and store non-sensitive study materials. Privacy during the data collection process was prioritized and the majority (72.7%) of the prisons sampled contained a private space to conduct the study.
Safety and security of research team
The research team’s manifestation of interest in carrying out the research in the establishments led the directors of each establishment to guarantee the safety of the team within the facilities requiring guards to escort study teams, transport inmates to the study area and provide extra security. In all prisons sampled, the availability of mechanisms and security devices was guaranteed in these terms. Such availability would reduce the number of inmates outside their cells, the use of correctional officers escorting study teams, and the need for guards to protect team members during BBS implementation. The involvement of both key correctional officials and a clinical focal point is crucial for conducting any public health research in prisons. The survey team (including investigators and interviewers) should be accompanied in designated areas (where the survey will be conducted) in the establishments (Table 2).
Possible barriers for study implementation
One of the major concerns with conducting a BBS in establishments is time management due to the establishments operating hours. It was agreed that the survey could only be conducted within the operating hours of state institutions (from 7:30 am to 3:30 pm). Gaining access into the establishment and proceeding through the necessary security checks can take up to thirty minutes for each study team member. The team also needs to consider the inmates’ mealtimes. Timing can impact the number of individuals that can be interviewed and the length of time that can be spent with them. Efficient planning will be key in successful BBS implementation.
Establishment laws, restrictions or permissions for research can change unannounced due to security, lockdowns, rebellions, or other situations that may disrupt survey implementation. Investigators need to be aware of this possibility and it is imperative to have members on the study team who are familiar with the system and functioning of prisons facilities.
The COVID-19 pandemic has undeniably changed the manner in which survey procedures are carried out and the impact extends to penitentiary establishments. Although incarcerated, prisoners are not isolated from the world and are therefore extremely vulnerable to SARS-CoV-2, since they congregate in areas with poor ventilation. In order to mitigate SARS-CoV-2 infection, a series of measures at national level were adopted. All establishment employ protocols to prevent the spread of COVID-19 in the penitentiary establishment. This fact plays an important role in the implementation of this survey, contributing equally to the safety of the members of the research team, as well as the participants. It should be noted due to current COVID-19 prevention protocols, the establishments limit the number of inmates who can be outside of their cells at a given time. The majority (54.5%) of penitentiary establishments allowed 5–10 inmates out of their cells at any time. About a quarter (27.3%) of penitentiary establishments only allowed 1–5 inmates out of their cells at a time. How inmates are recruited to be BBS participants, the limitation on the number of inmates allowed out of their cells directly impacts BBS implementation, specifically the amount of time full participation would be required.
The penitentiary establishment is a self-contained environment in which activities are strictly regulated and monitored. According to research norms and principles in Mozambique, including IRB, there is a need for additional protection for vulnerable populations in general and incarcerated persons specifically. The informed consent documentation states that participation of an incarcerated person in research is voluntary and should not affect parole or correctional programming decisions. Unlike other surveys where participants can call the principal investigator at any time to request clarifications or report adverse events, in this environment the participants do not have as much autonomy. Participants must therefore receive enough and understandable information to make a voluntarily informed decision. Another important aspect is participation bias. The arrival of the research team in the closed environment can, in itself, affect incarcerated perceptions of the institutions in which they live. Prisoners may be more inclined to participate in a study simply because it would involve getting the attention of an interviewer. On the other hand, incarcerated people may be suspicious of researchers. Establishing trust to collect accurate information is very important and crucial.
About three quarters (77.3%) of the penitentiary establishments sampled reported having an internal health facility to provide care to inmates and other people in the establishment. However, the majority of respondents (directors and/or their substitutes) referred to mobile clinics that travel to penitentiary establishments to provide healthcare services to inmates in need. On other occasions, inmates are taken to the reference health facility for more private care. It was also mentioned that some prisons receive weekly visits from a health professional.
About 23% of penitentiary establishments don’t have a community-based organization that works with inmates on the establishment. The community-based organizations play a significant role on outreach and HIV/AINDS peer education.
Conclusion
Incarcerated persons are regarded as a vulnerable population for research study purposes, including the BBS. The opportunity to conduct a BBS should ultimately result in benefits for the inmates, for example by improving conditions or access to health services for vulnerable populations.
The implementation of successive and regular rounds of BBS in different environments, contexts and populations constitute opportunities for generating information and indicators not always captured by programmatic data and not only as an opportunity for offering and making healthcare available in prison environments that in a routine context, but these populations normally have also not had equal opportunities.
Currently, little is known about implementing a BBS in a correctional setting and only a few barriers can be anticipated. However, in the current context of Mozambique, these formative assessment show challenges and obstacles can be overcome through clear communication, collaboration with officials at all levels, from the individual prison to the Ministry of the Interior.
