RESUMEN

OBJECTIVES: While ethics has been identified as a core component of health technology assessment (HTA), there are few examples of practical, systematic inclusion of ethics analysis in HTA. Some attribute the scarcity of ethics analysis in HTA to debates about appropriate methodology and the need for ethics frameworks that are relevant to local social values. The "South African Values and Ethics for Universal Health Coverage" (SAVE-UHC) project models an approach that countries can use to develop HTA ethics frameworks that are specific to their national contexts. METHODS: The SAVE-UHC approach consisted of two phases. In Phase I, the research team convened and facilitated a national multistakeholder working group to develop a provisional ethics framework through a collaborative, engagement-driven process. In Phase II, the research team refined the model framework by piloting it through three simulated HTA appraisal committee meetings. Each simulated committee reviewed two case studies of sample health interventions: opioid substitution therapy and either a novel contraceptive implant or seasonal influenza immunization for children under five. RESULTS: The methodology was fit-for-purpose, resulting in a context-specified ethics framework and producing relevant findings to inform application of the framework for the given HTA context. CONCLUSIONS: The SAVE-UHC approach provides a model for developing, piloting, and refining an ethics framework for health priority-setting that is responsive to national social values. This approach also helps identify key facilitators and challenges for integrating ethics analysis into HTA processes.

RESUMEN

INTRODUCTION: Ritual circumcision complicated by gangrene is a leading cause of penile loss in young men in South Africa. This deeply rooted cultural tradition is unlikely to be abolished. Conventional reconstructive techniques using free vascularised tissue flaps with penile implants are undesirable in this often socioeconomically challenged group because donor site morbidity can hinder manual labour and vigorous sexual activity might lead to penile implant extrusion. The psychosociological effects of penile loss in a young man are devastating and replacing it with the same organ is likely to produce the maximum benefit. METHODS: We first performed a cadaver-to-cadaver penile transplantation as preparation. After approval from the Human Research Ethics Committee was obtained, we recruited potential recipients. We screened the potential participants for both physical and psychological characteristics, including penile stump length, and emotional suitability for the procedure. A suitable donor became available and the penis was harvested. We surgically prepared the penile stump of the recipient and attached the penile graft. Immunosuppression treatment with antithymyocyte globulin, methylprednisolone, tacrolimus, mycophenolate mofetil, and prednisone were commenced. Tadalafil at 5 mg once per day was commenced after 1 week as penile rehabilitation and was continued for 3 months. We collected on quality-of-life scores (Short Form 36 version 2 [SF-36v2] questionnaires) before surgery and during follow-up and measured erectile function (International Index for Erectile Function [IIEF] score) and urine flow rates at 24 months post transplant. FINDINGS: The warm ischaemia time for the graft after removal was 4 min and the cold ischaemia time was 16 h. The surgery lasted 9 h. An arterial thrombus required urgent revision 8 h after the operation. On post operative day 6, an infected haematoma and an area of proximal skin necrosis were surgically treated. The recipient was discharged after 1 month and first reported satisfactory sexual intercourse 1 week later (despite advice to the contrary). The recipient reported regular sexual intercourse from 3 months after the operation. An episode of acute kidney injury at 7 months was reversed by reducing the tacrolimus dose to 14 mg twice per day. At 8 months after surgery, the patient had a skin infection with phaeohyphomycosis due to Alternaria alternata, which we treated with topical antifungal medication. Quality-of-life scores improved substantially after the operation (SF-36v2 mental health scores improved from 25 preoperatively, to 57 at 6 months and 46 at 24 months post transplant; physical health scores improved from 37 at baseline to 60 at 6 months and 59 at 24 months post-transplant). At 24 months, measured maximum urine flow rate (16·3 mL/s from a volume voided of 109 mL) and IIEF score (overall satisfaction score of 8 from a maximum of 10) were normal, showing normal voiding and erectile function, respectively. INTERPRETATION: Penile transplantation restored normal physiological functions in this transplant recipient without major complications in the first 24 months.

RESUMEN

OBJECTIVES: This article explores the perceived value, including associated strengths and challenges, of using a context-specified ethics framework to guide deliberative health technology appraisals. METHODS: The South African Values and Ethics for Universal Health Coverage (SAVE-UHC) approach, piloted in South Africa, consisted of 2 phases: (1) convening a national multistakeholder working group to develop a provisional ethics framework and (2) testing the provisional ethics framework through simulated health technology assessment appraisal committee meetings (SACs). Three SACs each reviewed 2 case studies of sample health interventions using the framework. Participants completed postappraisal questionnaires and engaged in focus group discussions. RESULTS: The SACs involved 27 participants across 3 provinces. Findings from the postappraisal questionnaires demonstrated general support for the SAVE-UHC approach and content of the framework, high levels of satisfaction with the recommendations produced, and general sentiment that participants were able to actively contribute to appraisals. Qualitative data showed participants perceived using a context-specified ethics framework in deliberative decision making: (1) supported wider consideration of and deliberation about morally relevant features of the health coverage decisions, thereby contributing to quality of appraisals; (2) could improve transparency; and (3) offered benefits to those directly involved in the priority-setting process. Participants also identified some challenges and concerns associated with the approach. CONCLUSIONS: The SAVE-UHC approach presents a novel way to develop and pilot a locally contextualized, explicit ethics framework for health priority setting. This work highlights how the combination of a context-specified ethics framework and structured deliberative appraisals can contribute to the quality of health technology appraisals and transparency of health priority setting.

RESUMEN

BACKGROUND: Enhancing evidence-based practice and improving locally driven research begins with fostering the research skills of undergraduate students in the medical and health sciences. Research as a core component of undergraduate curricula can be facilitated or constrained by various programmatic and institutional factors, including that of choice. Self-Determination Theory (SDT) provides a framework for understanding the influence of choice on student motivation to engage in research. AIM: This study aimed to document the enablers and constraints of undergraduate research at a South African Faculty of Medicine and Health Sciences (FMHS) and to explore how the presence or absence of choice influenced students' engagement with research in this context. METHODS: An exploratory descriptive design was adopted. Undergraduate students who had conducted research and undergraduate programme staff were recruited through purposive sampling. Semi-structured interviews were transcribed and thematically analysed. Findings were interpreted using SDT, focusing on how choice at various levels affects motivation and influences research experiences. RESULTS: Many of the programmatic and institutional enablers and constraints-such as time and supervisory availability-were consistent with those previously identified in the literature, regardless of whether research was compulsory or elective. Choice itself seemed to operate as both an enabler and a constraint, highlighting the complexity of choice as an influence on student motivation. SDT provided insight into how programmatic and institutional factors-and in particular choice-supported or suppressed students' needs for autonomy, competence, and relatedness, thereby influencing their motivation to engage in research. CONCLUSION: While programmatic and institutional factors may enable or constrain undergraduate research, individual-level factors such as the influence of choice on students' motivation play a critical role. The implication for curriculum development is that research engagement might be enhanced if levels of choice are structured into the curriculum such that students' needs for autonomy, competence, and relatedness are met.

RESUMEN

HIV disproportionately affects women in developing countries, especially in Southern Africa. Women thus stand to benefit most from a successful HIV vaccine and must participate in trials to test appropriate, gender-specific products. Several HIV vaccine efforts are currently underway in Africa. Participation in HIV vaccine trials requires that participants not only understand the complex nature of trial procedures, but that they also have autonomous decisional capacity to enroll. Given that the risk factors inherent in women's greater vulnerability constitute an intricate mix of biological, economic and social variables, will women's very vulnerability to HIV be an obstacle to ethical participation in vaccine development? This paper addresses some of the challenges underlying the successful recruitment of women into vaccine research and makes research and policy recommendations for the ethical inclusion of women in HIV vaccine trials in Africa.
