Can sugar taxes be used for financing surgical systems in Nigeria? A mixed-methods political economy analysis.

This study determined the feasibility of investing revenues raised through Nigeria's sugar-sweetened beverage (SSB) tax of 10 Naira/l to support the implementation of the National, Surgical, Obstetrics, Anaesthesia and Nursing Plan, which aims to strengthen access to surgical care in the country. We conducted a mixed-methods political economy analysis. This included a modelling exercise to predict the revenues from Nigeria's SSB tax based on its current tax rate over a period of 5 years, and for several scenarios such as a 20% ad valorem tax recommended by the World Health Organization. We performed a gap analysis to explore the differences between fiscal space provided by the tax and the implementation cost of the surgical plan. We conducted qualitative interviews with key stakeholders and performed thematic analyses to identify opportunities and barriers for financing surgery through tax revenues. At its current rate, the SSB tax policy has the potential to generate 35 914 111 USD in year 1, and 189 992 739 USD over 5 years. Compared with the 5-year adjusted surgical plan cost of 20 billion USD, the tax accounts for ∼1% of the investment required. There is a substantial scope for further increases in the tax rate in Nigeria, yielding potential revenues of up to 107 663 315 USD, annually. Despite an existing momentum to improve surgical care, there is no impetus to earmark sugar tax revenues for surgery. Primary healthcare and the prevention and treatment of non-communicable diseases present as the most favoured investment areas. Consensus within the medical community on importance of primary healthcare, along the recent government transition in Nigeria, offers a policy window for promoting a higher SSB tax rate and an adoption of other sin taxes to generate earmarked funds for the healthcare system. Evidence-based advocacy is necessary to promote the benefits from investing into surgery.

Identifying critical gaps in research to advance global surgery by 2030: a systematic mapping review.

Progress on surgical system strengthening has been slow due to a disconnect between evidence generation and the information required for effective policymaking. This systematic mapping review sought to assess critical research gaps in the field of global surgery guided by the World Health Organisation Health Systems building block framework, analysis of authorship and funding patterns, and an exploration of emerging research partnership networks. Literature was systematically mapped to identify, screen, and synthesize results of publications in the global surgery field between 2015 and March 2022. We searched four databases and included literature published in seven languages. A social network analysis determined the network attributes of research institutions and their transient relationships in shaping the global surgery research agenda. We identified 2,298 relevant studies out of 92,720 unique articles searched. Research output increased from 453 in 2015-16 to 552 in 2021-22, largely due to literature on Covid-19 impacts on surgery. Sub-Saharan Africa (792/2298) and South Asia (331/2298) were the most studied regions, although high-income countries represented a disproportionate number of first (42%) and last (43%) authors. Service delivery received the most attention, including the surgical burden and quality and safety of services, followed by capacity-building efforts in low- and middle-income countries. Critical research in economics and financing, essential infrastructure and supplies, and surgical leadership necessary to guide policy decisions at the country level were lacking. Global surgical systems remain largely under-researched. Knowledge diffusion requires an emphasis on developing sustainable research partnerships and capacity across low- and middle-income countries. A renewed focus must be given to equipping countries with tools for effective decision-making to enhance investments in high-quality surgical services.

Assessing the impact of anaesthetic and surgical task-shifting globally: a systematic literature review.

The global shortage of skilled anaesthesiologists, surgeons and obstetricians is a leading cause of high unmet surgical need. Although anaesthetic and surgical task-shifting are widely practised to mitigate this barrier, little is known about their safety and efficacy. This systematic review seeks to highlight the existing evidence on the clinical outcomes of patients operated on by non-physicians or non-specialist physicians globally. Relevant articles were identified by searching four databases (MEDLINE, EMBASE, CINAHL and Global Health) in all languages between January 2008 and February 2022. Retrieved documents were screened against pre-specified inclusion and exclusion criteria, and their qualities were appraised critically. Data were extracted by two independent reviewers and findings were synthesized narratively. In total, 40 studies have been included. Thirty-five focus on task-shifting for surgical and obstetric procedures, whereas four studies address anaesthetic task-shifting; one study covers both interventions. The majority are located in sub-Saharan Africa and the USA. Seventy-five per cent present perioperative mortality outcomes and 85% analyse morbidity measures. Evidence from low- and middle-income countries, which primarily concentrates on caesarean sections, hernia repairs and surgical male circumcisions, points to the overall safety of non-surgeons. On the other hand, the literature on surgical task-shifting in high-income countries (HICs) is limited to nine studies analysing tube thoracostomies, neurosurgical procedures, caesarean sections, male circumcisions and basal cell carcinoma excisions. Finally, only five studies pertaining to anaesthetic task-shifting across all country settings answer the research question with conflicting results, making it difficult to draw conclusions on the quality of non-physician anaesthetic care. Overall, it appears that non-specialists can safely perform high-volume, low-complexity operations. Further research is needed to understand the implications of surgical task-shifting in HICs and to better assess the performance of non-specialist anaesthesia providers. Future studies must adopt randomized study designs and include long-term outcome measures to generate high-quality evidence.

Organizational peer support to enable rehabilitating surgical services in Northern Ethiopia.

The ongoing violent conflict in Northern Ethiopia has caused displacement, death, and destruction. Health services infrastructure became one of the primary victims of the war, leaving millions unable to access essential surgical health services at a time when demand for surgical interventions is on the rise. Rehabilitating surgical services was identified as a priority by the federal government, regional health bureaus, and humanitarian organizations, forming an integral part in rebuilding communities after war. Under the auspices of the Federal Ministry of Health of Ethiopia, a hospital twinning program between providers in non-conflict and conflict affected areas was first introduced in December 2021, now including 13 active partnerships. The program builds on a previous best practice gained from the Ethiopian Hospital Alliance for Quality to strengthen local health care providers in regaining capabilities to serve local populations. Field experience of two hospital twinning projects have shown significant scope of organizational peer support at times of crisis, successfully enabling conflict-afflicted hospitals to regain the capacity necessary to re-introduce surgical services. While overcoming challenges such as lack of basic supplies including electricity and blood may be required to further increase the scope of this program in Northern Ethiopia, relative success highlights important lessons for similar approaches in areas affected by conflict, or natural disasters.
