The Millennium Development Goals have ended and the Sustainable Development Goals have begun, marking a shift in the global health landscape. The frame of reference has changed from a focus on 8 development priorities to an expansive set of 17 interrelated goals intended to improve the well-being of all people. In this time of change, several groups, including the Lancet Commission on Global Surgery, have brought a critical problem to the fore: 5 billion people lack access to safe, affordable surgical and anaesthesia care when needed. The magnitude of this problem and the worlds new focus on strengthening health systems mandate reimagined roles for and renewed commitments from high income country actors in global surgery. To discuss the way forward, on 6 May 2015, the Commission held its North American launch event in Boston, Massachusetts. Panels of experts outlined the current state of knowledge and agreed on the roles of surgical colleges and academic medical centres; trainees and training programmes; academia; global health funders; the biomedical devices industry, and news media and advocacy organisations in building sustainable, resilient surgical systems. This paper summarises these discussions and serves as a consensus statement providing practical advice to these groups. It traces a common policy agenda between major actors and provides a roadmap for maximising benefit to surgical patients worldwide. To close the access gap by 2030, individuals and organisations must work collectively, interprofessionally and globally. High income country actors must abandon colonial narratives and work alongside low and middle income country partners to build the surgical systems of the future.

BackgroundLaparoscopic cholecystectomy is first-line treatment for uncomplicated gallstone disease in high-income countries due to benefits such as shorter hospital stays, reduced morbidity, more rapid return to work, and lower mortality as well-being considered cost-effective. However, there persists a lack of uptake in low- and middle-income countries. Thus, there is a need to evaluate laparoscopic cholecystectomy in comparison with an open approach in these settings.MethodsA cost–effectiveness analysis was performed to evaluate laparoscopic and open cholecystectomies at Rwanda Military Hospital (RMH), a tertiary care referral hospital in Rwanda. Sensitivity and threshold analyses were performed to determine the robustness of the results.ResultsThe laparoscopic and open cholecystectomy costs and effectiveness values were

3975/QALY.ConclusionsAt RMH, while laparoscopic cholecystectomy may be a more effective approach, it is also more expensive given the low caseload and high investment costs. At commonly accepted WTP thresholds, it is not cost-effective. However, as investment costs decrease and/or case volume increases, the laparoscopic approach may become favorable. Countries and hospitals should aspire to develop innovative, low-cost options in high volume to combat these barriers and provide laparoscopic surgery.

As genomic medicine gains clinical applicability across a spectrum of diseases, insufficient application in low-income settings stands to increase health disparity. Breast cancer screening, diagnosis, and treatment have benefited greatly from genomic medicine in high-income settings. As breast cancer is a leading cause of both cancer incidence and mortality in Africa, attention and resources must be applied to research and clinical initiatives to integrate genomic medicine into breast cancer care. In terms of research, there is a paucity of investigations into genetic determinants of breast cancer specific to African populations, despite consensus in the literature that predisposition and susceptibility genes vary between populations. Therefore, we need targeted strengthening of existing research efforts and support of new initiatives. Results will improve clinical care through screening and diagnosis with genetic testing specific to breast cancer in African populations. Clinically, genomic medicine can provide information capable of improving resource allocation to the population which most stands to benefit from increased screening or tailored treatment modalities. In situations where mammography or chemotherapy options are limited, this information will allow for the greatest impact. Implementation of genomic medicine will face numerous systemic barriers but is essential to improve breast cancer outcomes and survival.
