Background: More than two-thirds of people living with HIV live in Sub-Saharan Africa, where the HIV prevalence in the adult population (aged 15-49) is 3.9%.
In these countries a critical issue is represented by low level of adherence to treatment particularly in HIV positive pregnant women. Among the causes, the lack of male partner involvement represents a significant criticality. This issue emerge in Malawi, one of the countries with the highest prevalence of HIV in the world: 9.2% of the adult population living with HIV in 2018.
Objective: to assess three different interventions aimed at improving adherence and retention to Anti Retroviral therapy among HIV positive women through engagement with their life partner in four Malawian healthcare centres.
Methods: The prospective, controlled before-and-after study is articulated in three phases (total 24 months): pre-intervention, intervention and post-intervention analyses. The number of selected clinical centres is limited to four, one for each intervention plus a centre where no intervention will be performed (control arm). The interventions are 1) opening the facility on Saturday a month, only for men, defined "special day"; 2) peer-to-peer counselling among men, "male champions"; 3) providing incentive to all women accompanied by their partners at the facility, "nudge" (note1).
The primary outcome of the study is the evaluation of the variations in retention in care and women's adherence to therapeutic protocols; the intermediate outcome is the assessment of the variations in Male Involvement (MI).
The level of MI in the health of female partners (intermediate outcome) will be evaluated through a questionnaire administered at baseline and in the post-intervention phase. Data will be collected at the clinical centres and will be stored in two electronic databases.
Results: Analysis of data collected in the four centres during the pre-intervention phase is on-going as the enrolment is stopped 31st March 2020. Total patients enrolled are 452 (133 Namandanje: 133, Kapeni: 78, Kapire: 75, Balaka: 166). Meantime, several meetings are performed in the centres to organize the intervention phase.
Conclusions: The study will identified the better intervention to involve male partners in women's health according to an approach based on a broad spectrum of behaviours.
Full description
The design is a prospective controlled study, that is suitable for the evaluation of promising interventions to improve male involvement and enhance maternal adherence to HIV PMTCT.
For this study, we adopted a framework based on the ecological model adapted by Kaufman et al to health behaviors in HIV prevention.
According to the ecological model, many factors affect male involvement in women's health care processes at different levels. In this study, we focused on individual level, interpersonal and network (eg, family and peers), community, health system (health facility level), and structural level (eg, access to transportation).
The aim of the study is to evaluate 3 different interventions aimed at improving adherence and retention to Anti Retroviral therapy among HIV-positive women through engagement with their life partner. The interventions are (1) testing peer-to-peer counseling and community-level health education sessions delivered by men, male champions; (2) opening the facility once a month, only for men, special day; and (3) providing incentive to all women accompanied by their partners at the facility, nudge or incentive (note1).
The study has 3 phases: preintervention (baseline), intervention, and postintervention analyses, as shown in Figure 2.
In the preintervention analysis, the baseline situation of the 3 participating centers will be evaluated. The aim of this phase is to set a starting point to weigh the relative effect of each intervention to be studied. For that purpose, baseline data of each study site will be collected. To evaluate the effect of the interventions, the same indicators will be measured during the pre- and postintervention phases, as described above. The preintervention phase will last 9 months. During this period, data will be collected at each site and included in a database.
Given the limited resources available for the study and the practical difficulties related to the disadvantaged context in which the study was conducted, sample size calculations and criteria for assigning interventions were based on a pragmatic approach. The number of selected clusters is limited to 4, one for each intervention plus a cluster where no intervention will be performed as a control arm. The number of participants enrolled for data collection is given by the number of patients attending the selected clinical centers during the pre- and postintervention phases. Therefore, the main unit of analysis of the study is the cluster, which is the clinical center. Thus, the interventions will target each health facility.
The following criteria were followed to select the 4 centers included in the intervention:
Although the unit of analysis is the clinical center, and therefore all patients who are referred, the study focuses on the population of adult females and the influence of male partners on the health practices of women. Therefore, data will be collected from this specific population. Eligibility criteria for women included the following: being HIV positive; inclusion in an HIV/AIDS prevention and treatment program; aged 18 years or older; and living at home with a male partner.
The enrollment of participants will be consecutively based on the order of patient appointments. Recruitment will be entrusted to doctors and clinical officers responsible for the medical visits of women participating in HIV treatment programs, who interact with patients during every visit to the clinical center. All women who met the eligibility criteria and agreed to participate in the study will be enrolled. Recruitment will be conducted before the medical examination: the software used for patient management reports to the clinician whether patients aged less than 18 years are enrolled, allowing the clinician to check entry criteria and invite eligible participants for study participation with the provision of informed consent.
Data will be collected at the clinical centers and will be stored in 2 electronic databases managed through 2 different types of software:
In the preintervention phase, data will be collected at the medical visit immediately after the enrollment visit to evaluate the partner's acceptance of the invitation to come to the clinical center for testing and counseling in the company of the patient. In the postintervention phase, data will be collected 2 months from enrollment to allow for a wash-out period where the effects of the interventions would be expressed.
The interventions will be implemented according to standard clinical practices in Malawi with some modifications based on the international experiences described in the literature.
The educational tools developed for these interventions are based on standards adopted in the country for couples counseling on HIV/AIDS. To these standard guidelines, messages were added to initiate a reflective discussion of stereotypes and false beliefs related to the idea of masculinity in the Malawian culture. All staff involved in the delivery of these interventions were provided with a guide (included in Multimedia Appendix 1) on the contents to be delivered. They also participated in a one-day training of the themes of the project. The guide was developed by study investigators and Malawian health care staff. The guide was based on tools developed and applied in other contexts with the purpose of increasing men's access to health care services and to reduce stereotypes and gender-based violence. It was also based on the ecological model.
The educational content will be delivered using 3 different approaches. The special day arm will address the community in the catchment area of the clinical center, but the intervention will take place at the facility level. Through visibility activities such as leaflet distributions or information campaigns with audio messages, men living in the communities surrounding the treatment center will be invited to an extraordinary opening day at the center dedicated only to men. During the special day, the center's clinical staff will offer basic health care services such as HIV testing and counseling, blood pressure measurement and counseling on cardiovascular disease, blood glucose measurement and counseling on diabetes, and nutritional evaluation and counseling. During the morning, group educational activities led by male community health care workers together with the doctors of the center and 2 educational sessions using drama techniques will be conducted. In the male champions arm, the intervention will be conducted at the level of regional and religious communities, with group educational sessions and use of the male champions. Male champions will be selected from patients receiving treatment for HIV for more than a year at the local DREAM centers. The educational sessions, based on an interactive approach with questions and answers both from the audience and the male champions, will last between 30 min to an hour. The male champion will be allowed to prolong the intervention if the audience requests it. Meetings will be planned and implemented in communities where at least five patients who receive treatment at DREAM centers reside, including religious communities in those regions. In the nudge arm, the intervention will be directed to individuals or to male partners of female patients being treated at DREAM centers. Women who agree to participate in the study will be asked to invite their male partners to the center for a health education session, and male partners who agree to participate will receive an incentive for attending the service in the form of a food package (note1). At the second visit, the couple will be given a health education session based on educational materials prepared for the study.
