RESUMO

BACKGROUND: The involvement of pregnant women in vaccine clinical trials presents unique challenges for the informed consent process. We explored the expectations and experiences of the pregnant women, spouses/partners, health workers and stakeholders of the consent process during a Group B Streptococcus maternal vaccine trial. METHODS: We interviewed 56 participants including pregnant women taking part in the trial, women not in the trial, health workers handling the trial procedures, spouses, and community stakeholders. We conducted 13 in-depth interviews and focus group discussions with 23 women in the trial, in-depth interviews with 5 spouses, and 5 women not in the trial, key informant interviews with 5 health workers and 5 other stakeholders were undertaken. RESULTS: Decision-making by a pregnant woman to join a trial was done in consultation with spouse, parents, siblings, or trusted health workers. Written study information was appreciated by all but they suggested the use of audio and visual presentation to enhance understanding. Women stressed the need to ensure that their male partners received study information before their pregnant partners joined a clinical trial. Confidentiality in research was emphasised differently by individual participants; while some emphasised it for self, others were keen to protect their family members from being exposed, for allowing them to be involved in research. However, others wanted their community participation to be acknowledged. CONCLUSION: We found that pregnant women make decisions to join a clinical trial after consulting with close family. Our findings suggest the need for an information strategy which informs not only the pregnant woman, but also her family about the research she is invited to engage in.

RESUMO

BACKGROUND: Understanding the knowledge, perception and attitudes towards Ebola vaccines is an important factor in ensuring future use of these vaccines. A qualitative methods study embedded in an Ebola vaccine immunogenicity and safety trial (NCT04028349) was conducted to explore the knowledge and perceptions of healthcare (HCWs) and frontline workers (FLWs), about Ebola vaccines and their willingness to participate or recommend participation in Uganda. METHOD: We carried out focus group discussions and semi-structured interviews before and after vaccination, with 70 HCWs and FLWs who consented to participate in the trial, and in the qualitative component, from August to September 2019. Data were analysed using thematic content analysis. RESULTS: Respondents showed good knowledge about Ebola and the vaccines in general, and had wide access to information through several channels, including the study team. On prevention, particular attention was given to effective communication within health facilities. Misconceptions were mainly around route of transmission, animal origin and types of vaccines. Previous fears were based on rumours circulating in the community, mainly about the presence of the virus in the vaccine, side effects and intention to harm (e.g. by "the whites"), ultimately insisting on transparency, trust and involvement of local leaders. Acceptability of participation was motivated by the need to protect self and others, and the willingness to advance research. Majority were willing to recommend participation to their community. CONCLUSIONS: Overall, information sharing leads to a better understanding and acceptance of vaccine trials and a positive vaccination experience can be a deciding factor in the acceptance of others. Particular attention should be paid to involving the community in addressing misconceptions and fears, while ensuring that participants have access to vaccination sites in terms of transport, and that they are properly accommodated at the study site including staying for a reasonable period of time.

RESUMO

HIV-associated cryptococcal meningitis remains a key driver of AIDS-related mortality. Mortality is twice as high in those who present later to care and with severe symptoms such as confusion. We embedded a qualitative methods study within a randomised controlled trial in Gaborone, Botswana and Kampala, Uganda with the aim of understanding pathways to care. We conducted in-depth interviews with trial participants and surrogate decision makers and analysed data thematically. Between January 2020 and June 2021 we interviewed 58 individuals. Pathways to care were prolonged because headaches were disregarded by participants and healthcare workers as a common occurrence with a broad differential diagnosis of predominantly benign aetiologies. There was also a lack of awareness of cryptococcal meningitis, and it was often after HIV was diagnosed or disclosed that the pathway accelerated, resulting in hospital admission. We outline key recommendations to reduce mortality and argue for the integration of social and behavioural interventions within differentiated service delivery models for advanced HIV disease.

RESUMO

Control of schistosomiasis depends on a single drug, praziquantel, with variable cure rates, high reinfection rates, and risk of drug resistance. A vaccine could transform schistosomiasis control. Preclinical data show that vaccine development is possible, but conventional vaccine efficacy trials require high incidence, long-term follow-up, and large sample size. Controlled human infection studies (CHI) can provide early efficacy data, allowing the selection of optimal candidates for further trials. A Schistosoma CHI has been established in the Netherlands but responses to infection and vaccines differ in target populations in endemic countries. We aim to develop a CHI for Schistosoma mansoni in Uganda to test candidate vaccines in an endemic setting. This is an open-label, dose-escalation trial in two populations: minimal, or intense, prior Schistosoma exposure. In each population, participants will be enrolled in sequential dose-escalating groups. Initially, three volunteers will be exposed to 10 cercariae. If all show infection, seven more will be exposed to the same dose. If not, three volunteers in subsequent groups will be exposed to higher doses (20 or 30 cercariae) following the same algorithm, until all 10 volunteers receiving a particular dose become infected, at which point the study will be stopped for that population. Volunteers will be followed weekly after infection until CAA positivity or to 12 weeks. Once positive, they will be treated with praziquantel and followed for one year. The trial registry number is ISRCTN14033813 and all approvals have been obtained. The trial will be subjected to monitoring, inspection, and/or audits.

RESUMO

BACKGROUND: We investigated pregnant women and community leaders' knowledge, perceptions and experiences of the coronavirus disease 2019 (COVID-19) vaccination program during pregnancy in Uganda and how this changed over the course of the pandemic. METHODS: We conducted 20 in-depth interviews (IDIs) and two group discussions (GDs) with pregnant women and four GDs with community leaders in Kawempe division of Kampala, Uganda. The first round of IDIs/GDs were carried out in March 2021. In July 2021, telephone IDIs were conducted with 7 pregnant women and 10 community leaders randomly selected from first-round interview participants. Themes were analysed deductively drawing codes from the topic guides. RESULTS: In the first round, the majority of participants thought COVID-19 was not real because of misconceptions around government messaging/motivation and beliefs that Africans would not be affected. In the second round, participants recognised COVID-19 disease, because of rising case numbers and fatalities. There was increased awareness of the benefits of the vaccine. However, pregnant women remained unsure of vaccine safety and quality, citing side effects like fevers and general body weakness. Role models and coherent public health messaging and healthcare workers were key enablers of vaccine uptake. CONCLUSIONS: Targeted and sustained COVID-19 communication and engagement strategies are needed, especially for pregnant women and others in their communities, to improve vaccine confidence during outbreaks.

RESUMO

BACKGROUND: Research into life-threatening illnesses which require emergency hospitalisation is essential. This group of patients is unique in that they are experiencing an unfolding emergency when they are approached, enrolled, and followed up in a research study. We aimed to synthesise qualitative data from trial participants and surrogate decision-makers to deepen our understanding and inform the design and conduct of future clinical trials for life-threatening illnesses. METHODS: We conducted a critical interpretive synthesis of qualitative data from trial participants and surrogate decision-makers related to the experience of participating in a clinical research study when suffering from a life-threatening illness. A scoping review informed a systematic review of published data. We searched research databases and reviewed papers for inclusion. Primary data and interpretations of data were extracted from each paper. Data were analysed using reciprocal translational analysis, refutational synthesis, and lines of argument synthesis to develop a synthetic construct. RESULTS: Twenty-two papers were included. Most individuals had no previous knowledge or experience with clinical research. Individuals making decisions were directly experiencing or witness to an unfolding emergency which came with a myriad of physical and psychological symptoms. It was difficult to differentiate clinical research and routine care, and understanding of core concepts around research, particularly randomisation and equipoise, was limited. We found that this led to an underestimation of risk, an overestimation of benefit, and an expectation of being allocated to the intervention arm. The decision-making process was heavily influenced by trust in the research team. Individuals suggested that abbreviated information, presented in different ways and continuously throughout the research process, would have increased knowledge and satisfaction with the research process. CONCLUSION: Individuals suffering from a life-threatening illness who are being invited to participate in clinical research need to be managed in a way that adapts to the severity of their illness and there is a need to tailor research processes, including informed consent, accordingly. We provide suggestions for further research and implementation work around research participation for individuals suffering from a life-threatening illness.

RESUMO

BACKGROUND: Schistosomiasis is a neglected tropical disease and a serious global-health problem with over 230 million people requiring treatment, of which the majority live in Africa. In Uganda, over 4 million people are infected. Extensive parasitological data exist on infection prevalence, intensities and the impact of repeated praziquantel mass drug administration (MDA). However, how perceptions of schistosomiasis shape prevention and treatment practices and their implications for control measures are much less well understood. METHODS: Rapid ethnographic appraisals were performed for six weeks in each of three Schistosoma mansoni high endemicity communities on the shores of Lake Victoria, Mayuge District, Uganda. Data were collected between September 2017 and April 2018. Data were collected through structured observations, transect walks, and participant observation, and sixty in-depth interviews and 19 focus group discussions with purposively recruited participants. Data were analyzed thematically using iterative categorization, looking at five key areas: perceptions of 1) the symptoms of schistosomiasis; 2) the treatment of schistosomiasis; 3) how schistosomiasis is contracted; 4) how schistosomiasis is transmitted onwards and responsibilities associated with this; and 5) how people can prevent infection and/or onward transmission. RESULTS: Observations revealed open defecation is a common practice in all communities, low latrine coverage compared to the population, and all communities largely depend on lake water and contact it on a daily basis. Perceptions that a swollen stomach was a sign/symptom of 'ekidada' (caused by witchcraft) resulted in some people rejecting free praziquantel in favour of herbal treatment from traditional healers at a fee. Others rejected praziquantel because of its perceived side effects. People who perceived that schistosomiasis is caught from drinking unboiled lake water did not seek to minimize skin contact with infected water sources. Community members had varied perceptions about how one can catch and transmit schistosomiasis and these perceptions affect prevention and treatment practices. Open defecation and urinating in the lake were considered the main route of transmission, all communities attributed blame for transmission to the fishermen which was acknowledged by some fishermen. And, lastly, schistosomiasis was considered hard to prevent due to lack of access to safe water. CONCLUSION: Despite over 15 years of MDA and associated education, common misconceptions surrounding schistosomiasis exist. Perceptions people have about schistosomiasis profoundly shape not only prevention but also treatment practices, greatly reducing intervention uptake. Therefore, we advocate for a contextualized health education programme, alongside MDA, implementation of improved access to safe-water and sanitation and continued research.

RESUMO

Children born to women who sell sex for money or commodities may face economic and social insecurity because of their mother's work, particularly in settings where sex work is illegal. From October 2020 to May 2021, we conducted a study with 60 children aged 12-24 years, born to sex workers in Kampala, Uganda. The children took part in 60 semi-structured interviews, 20 life history interviews, and 4 focus group discussions, which were used to explore their social, economic, and mental health experiences and investigate their vulnerabilities and resilience. Quantitative data were collected using REDcap, and descriptive analysis was done using Stata 14. Qualitative data were collected using semi-structured topic guides, and data analysed thematically. We explored findings in relation to a wellbeing framework. The findings showed that children experienced contextual and structural hardships, including incomplete and irregular schooling, a lack of privacy at home, food insecurity, and physical and psychological violence from relatives and sometimes from their mothers. Some children reported mental wellbeing struggles with hopelessness, nervousness, and sadness. Alcohol and drug use were common in most families. Community social network support systems, including neighbours and grandparents, were important; most children had absentee fathers. Some children suspected or knew how their mother earned her income. Resilience for most children was tagged to support from close networks and financial support from the government and civil society. Children of sex workers in Kampala experience structural, contextual, and mental health challenges but have a positive attitude towards the future. It is important to strengthen community support systems for these children and those living in similar circumstances in low- and middle-income countries.

RESUMO

We estimated the prevalence and factors associated with the use of a dedicated HIV prevention, care, and treatment service for female sex workers (FSWs) in Kampala, Uganda. Between October 2017 to January 2018, we conducted a cross-sectional study among FSWs at a dedicated clinic. We defined use as the use of the HIV prevention, care, and treatment services by FSWs at least once within the past six months. We used the log-binomial model to determine the factors associated with use of clinic services. Eight hundred and seventy-four women were included in the analysis. The overall prevalence of use of clinic services was 81%. At adjusted analysis, use of clinic services was independently associated with being HIV positive and being treated for STIs in the past three months. The prevalence of use of clinic services was high. Dedicated services for FSWs are required to support their use of HIV and STI care.

RESUMO

BACKGROUND: The AMBITION-cm trial for HIV-associated cryptococcal meningitis demonstrated that a single, high-dose of liposomal amphotericin (AmBisome) plus 14-days of oral flucytosine and fluconazole was non-inferior in terms of all-cause mortality to 7-days of amphotericin B deoxycholate and flucytosine followed by 7-days of fluconazole (Control). The AmBisome regimen was associated with fewer adverse events. We explored the acceptability of the AmBisome regimen from the perspective of participants and providers. METHODS: We embedded a qualitative methods study within the AMBITION-cm sites in Botswana and Uganda. We conducted in-depth interviews with trial participants, surrogate decision makers, and researchers and combined these with direct observations. Interviews were transcribed, translated, and analysed thematically. RESULTS: We interviewed 38 trial participants, 20 surrogate decision makers, and 31 researchers. Participant understanding of the trial was limited; however, there was a preference for the AmBisome regimen due to the single intravenous dose and fewer side effects. More time was required to prepare the single AmBisome dose but this was felt to be acceptable given subsequent reductions in workload. The AmBisome regimen was reported to be associated with fewer episodes of rigors and thrombophlebitis and a reduction in the number of intravenous cannulae required. Less intensive monitoring and management was required for participants in the AmBisome arm. CONCLUSIONS: The AmBisome regimen was highly acceptable, being simpler to administer despite the initial time investment required. The regimen was well tolerated and associated with less toxicity and resultant management. Widespread implementation would reduce the clinical workload of healthcare workers caring for patients with HIV-associated cryptococcal meningitis.

RESUMO

Issues related to controlled human infection studies using Schistosoma mansoni (CHI-S) were explored to ensure the ethical and voluntary participation of potential CHI-S volunteers in an endemic setting in Uganda. We invited volunteers from a fishing community and a tertiary education community to guide the development of informed consent procedures. Consultative group discussions were held to modify educational materials on schistosomiasis, vaccines and the CHI-S model and similar discussions were held with a test group. With both groups, a mock consent process was conducted. Fourteen in-depth key informant interviews and three group discussions were held to explore perceptions towards participating in a CHI-S. Most of the participants had not heard of the CHI-S. Willingness to take part depended on understanding the study procedures and the consenting process. Close social networks were key in deciding to take part. The worry of adverse effects was cited as a possible hindrance to taking part. Volunteer time compensation was unclear for a CHI-S. Potential volunteers in these communities are willing to take part in a CHI-S. Community engagement is needed to build trust and time must be taken to share study procedures and ensure understanding of key messages.

RESUMO

Potential participants for clinical trials which aim to define treatments for life-threatening conditions are often extremely unwell. When exploring why individuals participate in clinical trials one common observation is a misplaced expectation of personal benefit - a therapeutic misconception. The care offered in some clinical trials is of a higher standard than is routinely available and this has led to criticism around the freedom of choice to enrol - structural coercion. We embedded an ethnographic study within a randomised controlled trial for HIV-associated cryptococcal meningitis in Gaborone, Botswana and Kampala, Uganda. We aimed to gain an understanding of decision-making around the trial and how this was impacted by the study design and broader social context. We conducted in-depth interviews with trial participants, surrogate decision makers and researchers, combined these with direct observations and analysed data using thematic analysis. Between January 2020 and June 2021 we interviewed 89 individuals. We found previous exposure to and awareness of clinical research was limited, as was understanding of the trial objectives and design. Through observations and engagement with healthcare facilities decision-makers were able to identify the trial as providing the best possible chance of survival. Hesitation and reluctance were mostly due to fear of lumbar punctures which was sometimes based on rumours but often based on tragic personal experience. Despite fear, and sometimes conviction that they would die, individuals agreed to consent, often against the wishes of family members. Reassurance and confidence came from trust in routine care staff and the research team but also from fellow participants and their surrogates. We argue that participants made informed decisions based on a therapeutic expectation from the trial and that rather than being the result of structural coercion this was an informed and voluntary choice.

RESUMO

The unmet need for family planning among conflict-affected populations is high globally, leaving girls and women vulnerable to unintended pregnancies and poor sexual and reproductive health outcomes. Ours is the first known mixed-methods study to assess the use of modern family planning (FP) methods amongst married or partnered South Sudanese refugee and host populations in Northern Uganda and to explore differences between them. We conducted a cross-sectional survey in July 2019 which included 1,533 partnered women of reproductive age (15-49 years) from host and South Sudanese refugee communities in Kiryandongo and Arua. Qualitative data were collected in October 2019-January 2020 via 34 focus group discussions and 129 key informant interviews with refugee and host populations, health workers, community and religious leaders, health workers, local authorities and humanitarian actors. Our study did not find large differences between South Sudanese refugee and host populations in regard to modern FP use, though refugees reported somewhat poorer FP knowledge, accessibility and utilisation compared to Ugandan women. Reported barriers to FP use relate to access, quality of services, health concerns and family/community opposition, all of which emphasise the importance of men's gendered roles in relationships, cultural and religious beliefs and lack of agency for most women to make their own decisions about reproductive health. Sexual and gender-based violence related to FP use was reported among both refugee and host populations. Additional barriers to FP use include lack of privacy at the public health facilities which reduces confidentiality, mistrust of health workers, and stockouts of FP commodities. Facilitating factors for FP use included: free government health services; the presence of well-trained health workers; and NGOs who give support to populations and conduct community outreaches. The findings of this study underscore the importance of developing and implementing tailored sexual and reproductive health information and services, especially for modern FP methods, in partnership with South Sudanese refugee and host populations in Northern Uganda.

RESUMO

BACKGROUND: Over 240 million people are infected with schistosomiasis, the majority in sub-Saharan Africa. In Uganda, high infection rates exist in communities on the shores of Lake Victoria. Praziquantel mass drug administration (MDA) delivered by village health teams is the mainstay of schistosomiasis control. However, treatment uptake remains suboptimal, with many people unaware of treatment or thinking it is only for children. Furthermore, people are often rapidly reinfected post-treatment due to continued exposure. In three Schistosoma mansoni high endemicity lake-shore communities in Mayuge district, Eastern Uganda, we investigated the sources of schistosomiasis information, remembered content of information, and the perception of information and related practices towards the control of schistosomiasis. METHODS AND PRINCIPAL FINDINGS: Data were collected from September 2017 to March 2018 using a rapid ethnographic assessment that included transect walks, observations, individual in-depth interviews and focus group discussions. Data were analysed thematically using iterative categorisation. We found that the main sources of schistosomiasis information included health workers at government facilities, village health teams, teachers, and radio programmes produced by the Ministry of Health. These messages described the symptoms of schistosomiasis, but did not mention the side effects of praziquantel treatment. Despite this messaging, the main cause of the disease and transmission was unclear to most participants. The translation of schistosomiasis on the radio into the local language 'ekidada'-meaning swollen stomach-increased, rather than reduced, confusion about the cause(s) of schistosomiasis, due to believed links between ekidada and witchcraft, and prompted a reluctance to engage with treatment or preventative efforts. CONCLUSION AND SIGNIFICANCE: This study highlights gaps in schistosomiasis messaging. We recommend MDA is complemented by effective, evidence-based messaging on schistosomiasis transmission, prevention, and treatment, that is sensitive to local language and context issues, resulting in clear, concise, and consistent messages, to increase effectiveness.

RESUMO

BACKGROUND: Although cervical cancer is preventable, most women in sub-Saharan Africa (SSA) do not receive routine screening and few treatment options exist. Female Sex Workers (FSWs) are among the Ugandan female population at highest risk of acquiring sexually transmitted infections (STIs) including HIV and human papilloma viruses (HPV), the cause of cervical cancer. We report one-year experiences of visual inspection with acetic acid (VIA) positivity among FSWs in the early detection of pre-cancerous and cancerous cervical lesions in Kampala, Uganda. METHODS: Between June 2014 and July 2015, we enrolled FSWs into a cross-sectional study at a research clinic. The women were screened using the VIA method (application of 3-5 % acetic acid to the cervix). All VIA positive women were referred to a tertiary hospital for colposcopy, biopsy, and immediate treatment (if indicated) at the same visit according to national guidelines. Data on socio-demographic, sexual behaviour, sexual reproductive health and clinical characteristics were collected. We used logistic regression to identify factors associated with VIA positivity. RESULTS: Of 842 women assessed for eligibility, 719 (85 %) of median age 30 (IQR 26, 35) were screened, and 40 (6 %) women were VIA positive. Of the 24 histology specimens analysed, 6 showed inflammation, only 1 showed cervical intraepithelial neoplasia (CIN) 1, 13 women showed CIN2/3, while 4 women already had invasive cervical cancer. The overall prevalence of HIV was 43 %, of whom only 35 % were receiving ART. In the age-adjusted analysis, VIA positivity was more likely among women who reported having > 100 life-time partners (aOR = 3.34, 95 %CI: 1.38-8.12), and HIV positive women (aOR = 4.55; 95 %CI: 2.12-9.84). CONCLUSIONS: We found a relatively low proportion of VIA positivity in this population. The experience from our program implies that the VIA results are poorly reproducible even among a category of trained professional health workers. VIA positivity was more likely among women with a high number of sexual partners and HIV infection. Interventions for improving cervical cancer screening should be recommended as part of HIV care for FSWs to reduce the disease burden in this population.

RESUMO

INTRODUCTION: Individuals recruited into clinical trials for life-threatening illnesses are particularly vulnerable. This is especially true in low-income settings. The decision to enrol may be influenced by existing inequalities, poor healthcare infrastructure and fear of death. Where patients are confused or unconscious the responsibility for this decision falls to relatives. This qualitative study is nested in the ongoing AMBIsome Therapy Induction OptimisatioN (AMBITION) Trial. AMBITION is recruiting participants from five countries in sub-Saharan Africa and is trialling a novel treatment approach for HIV-associated cryptococcal meningitis, an infection known to affect brain function. We aim to learn from the experiences of participants, relatives and researchers involved in AMBITION. METHODS AND ANALYSIS: We will collect data through in-depth interviews with trial participants and the next of kin of participants who were confused at enrolment and therefore provided surrogate consent. Data will be collected in Gaborone, Botswana; Kampala, Uganda and Harare, Zimbabwe. Interviews will follow a narrative approach including participatory drawing of participation timelines. This will be supplemented by direct observation of the research process at each of the three recruiting hospitals. Interviews will also take place with researchers from the African and European institutions that form the partnership through which the trial is administered. Interviews will be transcribed verbatim, translated (if necessary) and organised thematically for narrative analysis. ETHICS AND DISSEMINATION: This study has been approved by the Health Research Development Committee, Gaborone (Reference: HPDME:13/18/1); Makerere School of Health Sciences Institutional Review Board, Kampala (Reference: 2019-061); University of Zimbabwe Joint Research Ethics Committee, Harare (Reference: 219/19), and the London School of Hygiene and Tropical Medicine (Reference: 17957). Study findings will be shared with research participants from the sites, key stakeholders at each research institution and ministries of health to help inform the development and implementation of future trials. The findings of this study will be published in journals and presented at academic meetings. TRIAL REGISTRATION: Registered at www.clinicaltrials.gov:NCT04296292.

RESUMO

BACKGROUND: We investigated how relevant and responsive scientists and research ethics committee (REC) members considered the research protocol review processes for health research practice in Uganda. METHODS: Interviews were conducted with five scientists and five REC members. Data were analysed thematically. RESULTS: How much to compensate for time, the amount of study information shared with volunteers and sample storage for future unknown research were areas of concern for REC members. Delays in getting feedback concerned scientists. CONCLUSIONS: Researchers and REC members need to hold regular discussions to ensure the review process is relevant and responsive.

RESUMO

INTRODUCTION: The reasons why research participants join clinical trials remains an area of inquiry especially in low and middle income countries. METHODS: We conducted exit interviews with participants who took part in a trial which aimed to evaluate whether long term prophylaxis with cotrimoxazole can be safely discontinued among adults who have been stabilised on antiretroviral therapy (ART). Participants were all reported to be stable on ART and had been participating in the trial for between 12 and 36 months; at the end of the trial participants were interviewed using a semi-structured questionnaire. One of the objectives of the exit interview was to find out what motivated the participants to join the research. RESULTS: Participants gave personal reasons for joining the trial, frequently linked to their health and well-being as well as reduction of pill burden. CONCLUSION: We conclude that underlying reasons for joining clinical trials may extend beyond or can be different from the rationale given to the participants before enrolment by the research team. The reasons that motivate enrolment to clinical trials and research in general require further investigation in different settings. TRIAL REGISTRATION NUMBER: ISRCTN44723643.

RESUMO

INTRODUCTION: In settings with low literacy levels ensuring that participants are fully-informed before they consent to participate in clinical trials is a challenge. We explored the experiences and concerns of key actors in the informed consent process in two HIV clinical trials. METHOD: Semi-structured interviews were conducted with 46 respondents including trial participants, research study team and research ethics committee members about their experiences during the informed consent process. Three focus group discussions were conducted with 14 Community Advisory Board (CAB) members and 17 trial participants. Data were analysed to identify key themes. FINDINGS: The consent process was highlighted as an important procedure by all the key actors however each group had a particular area of emphasis. Signing a consent form was given importance by research team and ethics committee members, because it provided documented evidence of a participant's willingness to join a clinical trial. Participants did not welcome the presence of a witness for a non-literate participant because understanding study information was not closely related to an ability to read and write. CONCLUSION: This study's findings indicated that obtaining a volunteer's signature or thumbprint on a consent form did not necessarily mean that the participant was fully-informed about the information relevant to their taking part nor that they understood all the information shared with them. Informed consent requires sufficient time in the research process to have staff trained well enough before research begins. Ensuring and gaining informed consent should be understood and treated as a relation-centred, dynamic supportive process throughout the duration of a research study.

RESUMO

BACKGROUND: Informed consent as stipulated in regulatory human research guidelines requires that a volunteer is well-informed about what will happen to them in a trial. However researchers are faced with a challenge of how to ensure that a volunteer agreeing to take part in a clinical trial is truly informed. We conducted a qualitative study among volunteers taking part in two HIV clinical trials in Uganda to find out how they defined informed consent and their perceptions of the trial procedures, study information and interactions with the research team. METHODS: Between January and December 2012, 23 volunteers who had been in the two trials for over 6 months, consented to be interviewed about their experience in the trial three times over a period of nine months. They also took part in focus group discussions. Themes informed by study research questions and emerging findings were used for content analysis. RESULTS: Volunteers defined the informed consent process in terms of their individual welfare. Only two of the volunteers reported having referred during the trial to the participant information sheets given at the start of the trial. Volunteers remembered the information they had been given at the start of the trial on procedures that involved drawing blood and urine samples but not information about study design and randomisation. Volunteers said that they had understood the purpose of the trial. They said that signing a consent form showed that they had consented to take part in the trial but they also described it as being done to protect the researcher in case a volunteer later experienced side effects. CONCLUSION: Volunteers pay more attention during the consent process to procedures requiring biological tests than to study design issues. Trust built between volunteers and the research team could enhance the successful conduct of clinical trials by allowing for informal discussions to identify and review volunteers' perceptions. These results point to the need for researchers to view informed consent as a process rather than an event.
