RESUMO
BACKGROUND: Improving the adoption and implementation of policies to curb non-communicable diseases (NCDs) is a major challenge for better global health. The adoption and implementation of such policies remain deficient in various contexts, with limited insights into the facilitating and inhibiting factors. These policies have traditionally been treated as technical solutions, neglecting the critical influence of political economy dynamics. Moreover, the complex nature of these interventions is often not adequately incorporated into evidence for policy-makers. This study aims to systematically review and evaluate the factors affecting NCD policy adoption and implementation. METHODS: We conducted a complex systematic review of articles discussing the adoption and implementation of World Health Organization's (WHO's) "best buys" NCD policies. We identified political economy factors and constructed a causal loop diagram (CLD) program theory to elucidate the interplay between factors influencing NCD policy adoption and implementation. A total of 157 papers met the inclusion criteria. RESULTS: Our CLD highlights a central feedback loop encompassing three vital variables: (1) the ability to define, (re)shape, and pass appropriate policy into law; (2) the ability to implement the policy (linked to the enforceability of the policy and to addressing NCD local burden); and (3) ability to monitor progress, evaluate and correct the course. Insufficient context-specific data impedes the formulation and enactment of suitable policies, particularly in areas facing multiple disease burdens. Multisectoral collaboration plays a pivotal role in both policy adoption and implementation. Effective monitoring and accountability systems significantly impact policy implementation. The commercial determinants of health (CDoH) serve as a major barrier to defining, adopting, and implementing tobacco, alcohol, and diet-related policies. CONCLUSION: To advance global efforts, we recommend focusing on the development of robust accountability, monitoring, and evaluation systems, ensuring transparency in private sector engagement, supporting context-specific data collection, and effectively managing the CDoH. A system thinking approach can enhance the implementation of complex public health interventions.

BACKGROUND: Non-communicable diseases (NCDs) are the world's leading cause of death and disability. Global implementation of WHO-recommended NCD policies has been increasing with time, but in 2019 fewer than half of these policies had been implemented globally. In 2022, WHO released updated data on NCD policy implementation, on the basis of surveys conducted in 2021 during the COVID-19 pandemic. We sought to examine whether the trajectory of global policy implementation changed during this period. METHODS: In this repeated cross-sectional analysis, we used data from the 2015, 2017, 2020, and 2022 WHO progress monitors to calculate NCD policy implementation scores for all 194 WHO member states. We used Welch's ANOVA and Games-Howell post-hoc pairwise testing to examine changes in mean implementation scores for 19 WHO-recommended NCD policies, with assessment at the global, geographical, geopolitical, and country-income levels. We collated sales data on tobacco, alcohol, and junk foods to examine the association between changes in sales and the predicted probability of implementation of policies targeting these products. We also calculated the Corporate Financial Influence Index (CFII) for each country, which was used to assess the association between corporate influence and policy implementation. We used logistic regression to assess the relationship between product sales and the probability of implementing related policies. The relationship between CFII and policy implementation was assessed with Pearson's correlation analysis and random-effects multivariate regression. FINDINGS: Across the 194 countries, in the years preceding publication of each progress monitor, mean total policy implementation score (out of a potential 18·0) was 7·0 (SD 3·5) in 2014, 8·2 (3·5) in 2016, 8·6 (3·6) in 2019, and 8·6 (3·6) in 2021. Only the differences in mean implementation score between 2014 and the other three report years were deemed statistically significant (pairwise p<0·05). Thus the steady improvement in mean global NCD policy implementation stalled in 2021 at 47·8%. However, from 2019 to 2021, we identified shifts in individual policies: global mean implementation scores increased for policies on tobacco, clinical guidelines, salt, and child food marketing, and decreased for policies on alcohol, breastmilk substitute marketing, physical activity mass media campaigns, risk factor surveys, and national NCD plans and targets. Six of the seven policies with the lowest levels of implementation (global mean score <0·4 out of a potential 1·0) in both 2019 and 2021 were related to tobacco, alcohol, and unhealthy food. From 2020 onwards, we identified weak or no associations between sales of tobacco, alcohol, and junk foods and the predicted probability of implementing policies related to each commodity. Country-level CFII was significantly associated with total policy implementation score (Pearson's r -0·49, 95% CI -0·59 to -0·36), and this finding was supported in multivariate modelling for all policies combined and for all commercial policies except alcohol policies. INTERPRETATION: NCD policy implementation has stagnated. Progress in the implementation of some policies is matched by decreased implementation of others, particularly those related to unhealthy commodities. To prevent NCDs and their consequences, and attain the Sustainable Development Goals, the rate of NCD policy adoption must be substantially and urgently increased before the next NCD progress monitor and UN high-level meeting on NCDs in 2024. FUNDING: None.

INTRODUCTION: There are many case studies of corporations that have worked to undermine health policy implementation. It is unclear whether countries that are more exposed to corporate financial influence are systematically less likely to implement robust health policies that target firms' financial interests. We aim to assess the association between corporate financial influence and implementation of WHO-recommended policies to constrain sales, marketing and consumption of tobacco, alcohol and unhealthy foods. METHODS AND ANALYSIS: We will perform a cross-sectional analysis of 172 WHO Member States using national datasets from 2015, 2017 and 2020. We will use random effects generalised least squares regression to test the association between implementation status of 12 WHO-recommended tobacco, alcohol and diet policies, and corporate financial influence, a metric that combines disclosure of campaign donations, public campaign finance, corporate campaign donations, legislature corrupt activities, disclosure by politicians and executive oversight. We will control for GDP per capita, population aged >65 years (%), urbanisation (%), level of democracy, continent, ethno-linguistic fractionalisation, legal origin, UN-defined 'Small Island Developing States' and Muslim population (%) (to capture alcohol policy differences). We will include year dummies to address the possibility of a spurious relationship between the outcome variable and the independent variables of interests. For example, there may be an upward global trend in policy implementation that coincides with an upward global trend in the regulation of lobbying and campaign finance. ETHICS AND DISSEMINATION: As this study uses publicly available data, ethics approval is not required. The authors have no conflicts of interest to declare. Findings will be submitted to a peer-reviewed journal for publication in the academic literature. All data, code and syntax will be made publicly available on GitHub.

OBJECTIVE: Non-communicable diseases (NCDs) are the leading cause of global death and disability. Tobacco, alcohol, and unhealthy foods are major contributing risk factors. WHO Member States have unanimously endorsed a set of 12 policies designed to constrain the sale of these commodities, however, there are myriad case studies of commercial entities seeking to undermine effective legislation in order to protect their profits. We set out to quantify the association between corporate financial influence and implementation of commercial policies. METHODS: We generated policy implementation scores for all 194 WHO Member States using data from the 2015, 2017, and 2020 WHO NCD Progress Monitor Reports. We used publicly available data to create a novel Corporate Financial Influence Index (CFII) that quantifies the opportunity for corporations to use their financial resources to directly influence policymaking in each country. We reported policy implementation trends over time and used random effects multivariate regression to test the association between policy implementation and CFII for each country, while controlling for broad set of economic, cultural, historical, geographic, and demographic factors. FINDINGS: Implementation of the 12 WHO-backed commercial policies has risen over time, but remains low at approximately 40%. Progress is reversing for alcohol policies. CFII explains around a fifth of the variance in global implementation. For every 10% rise in CFII, implementation falls by approximately 2% (95%CI 0.90 to 3.5, p < 0.001). CONCLUSION: Our quantitative global analysis suggests that financial corporate influence is negatively associated with implementation of policies that seek to restrict the marketing, sale, and consumption of unhealthy (but profitable) commodities. In the context of anemic international progress tackling NCDs, greater attention should be paid to managing regulatory opportunities for overt and covert corporate financial influence as a core plank of the global NCD response.

OBJECTIVE: This study aimed to use qualitative interviews with surgical providers to explore challenges and solutions to providing surgical and anaesthesia care in Sierra Leone's hospitals. DESIGN: Data were collected through anonymous, semistructured interviews. We used a qualitative framework approach to analyse interview data and determine themes relating to challenges that were reported. SETTING: A purposive sample of 12 hospitals was selected throughout Sierra Leone to include district and referral hospitals of varying ownership (private, non-governmental organisation and government). PARTICIPANTS: The most senior surgical provider available during each hospital site visit participated in a semistructured interview. A total of 12 interviews were conducted. RESULTS: Providers described both challenges and solutions relating to the following categories: equipment and supplies, access to services, human resources, infrastructure, management and patient factors. These challenges were found to affect surgical care in hospitals by delaying surgical care, decreasing operative capacity and decreasing quality of care. Providers identified not only the root causes of these challenges, but also the varied workarounds and solutions they employ to overcome them. CONCLUSION: Surgical providers can offer important insights into challenges affecting surgical services in hospitals. Despite working in challenging environments with limited resources, providers have developed innovative solutions to improve surgical and anaesthesia care in hospitals in Sierra Leone. Qualitative research has an important role to play in improving understanding of the challenges facing surgeons in low-income countries.

BACKGROUND: While primary data on the unmet need for surgery in low- and middle-income countries is lacking, household surveys could provide an entry point to collect such data. We describe the first development and inclusion of questions on surgery in a nationally representative Demographic and Health Survey (DHS) in Zambia. METHOD: Questions regarding surgical conditions were developed through an iterative consultative process and integrated into the rollout of the DHS survey in Zambia in 2018 and administered to a nationwide sample survey of eligible women aged 15-49 years and men aged 15-59 years. RESULTS: In total, 7 questions covering 4 themes of service delivery, diagnosed burden of surgical disease, access to care, and quality of care were added. The questions were administered across 12,831 households (13,683 women aged 15-49 years and 12,132 men aged 15-59 years). Results showed that approximately 5% of women and 2% of men had undergone an operation in the past 5 years. Among women, cesarean delivery was the most common surgery; circumcision was the most common procedure among men. In the past 5 years, an estimated 0.61% of the population had been told by a health care worker that they might need surgery, and of this group, 35% had undergone the relevant procedure. CONCLUSION: For the first time, questions on surgery have been included in a nationwide DHS. We have shown that it is feasible to integrate these questions into a large-scale survey to provide insight into surgical needs at a national level. Based on the DHS design and implementation mechanisms, a country interested in including a set of questions like the one included in Zambia, could replicate this data collection in other settings, which provides an opportunity for systematic collection of comparable surgical data, a vital role in surgical health care system strengthening.

BACKGROUND: Utilizing surgical services, including caesarean sections, can result in catastrophic expenditure and impoverishment. In 2010, Sierra Leone introduced the Free Health Care Initiative (FHCI), a national financial risk protection program for the most vulnerable groups. Aim of this study was to investigate catastrophic expenditure and impoverishment related to caesarean section in Sierra Leone and evaluate the impact of the FHCI. METHODS: Women who delivered by caesarean section in nine hospitals were followed up with home visits one month after surgery, and data on medical and non-medical expenditures were collected. Individual income was estimated based on household characteristics and used to determine catastrophic expenditure and impoverishment for each patient. The impact of the FHCI was assessed by comparing actual expenditure with counterfactual expenditures had the initiative not existed. RESULTS: For the 1146 patients in the study, the median expenditure was 23 (IQR 4; 56) international dollars (Int$). Patients in the poorest quintile spent a median Int$ 59 (IQR 28; 76), which was significantly more than patients in the richest quintile, who spent a median Int$ 17 (IQR 2; 38, p<0.001). Travel (32.9%) and food (28.7%) were the two largest expenses. Catastrophic expenditure was encountered by 12.0% and 4.0% (10% and 25% threshold, respectively) of the women. Without the FHCI, 66.1% and 28.8% of the women would have encountered catastrophic expenditure. CONCLUSION: Many women in Sierra Leone face catastrophic expenditure related to caesarean section, mainly through food and travel expenses, and the poor are disproportionally affected. The FHCI is effective in reducing the risk of catastrophic expenditure related to caesarean section, but many patients are still exposed to financial hardship, suggesting that additional support is needed for Sierra Leone's poorest patients.

BACKGROUND: Non-communicable diseases (NCDs) are the leading cause of morbidity and mortality globally. We aimed to analyse trends in implementation of WHO-recommended population-level policies and associations with national geopolitical characteristics. METHODS: We calculated cross-sectional NCD policy implementation scores for all 194 WHO member states from the 2015, 2017, and 2020 WHO progress monitor reports, and examined changes over time as well as average implementation by geographical and geopolitical region and income level. We developed a framework of indicators of national characteristics hypothesised to influence policy implementation, including democracy, corporate permeation (an indicator of corporate influence), NCD burden, and risk factor prevalence. We used multivariate regression models to test our hypotheses. FINDINGS: On average, countries had fully implemented a third (32·8%, SD 18·2) of the 19 policies in 2020. Using aggregate policy scores, which include partially implemented policies, mean implementation had increased from 39·0% (SD 19·3) in 2015 to 45·9% (19·2) in 2017 and 47·0% (19·8) in 2020. Implementation was lowest for policies relating to alcohol, tobacco, and unhealthy foods, and had reversed for a third of all policies. Low-income and less democratic countries had the lowest policy implementation. Our model explained 64·8% of variance in implementation scores. For every unit increase in corporate permeation, implementation decreased by 5·0% (95% CI -8·0 to -1·9, p=0·0017), and for every 1% increase in NCD mortality burden, implementation increased by 0·9% (0·2 to 1·6, p=0·014). Democracy was positively associated with policy implementation, but only in countries with low corporate permeation. INTERPRETATION: Implementation of NCD policies is uneven, but broadly improving over time. Urgent action is needed to boost implementation of policies targeting corporate vectors of NCDs, and to support countries facing high corporate permeation. FUNDING: The National Institutes for Health Research, the Swedish Research Council, the Fulbright Commission, and the Swedish Society of Medicine.

BACKGROUND: Indicators to evaluate progress towards timely access to safe surgical, anaesthesia, and obstetric (SAO) care were proposed in 2015 by the Lancet Commission on Global Surgery. These aimed to capture access to surgery, surgical workforce, surgical volume, perioperative mortality rate, and catastrophic and impoverishing financial consequences of surgery. Despite being rapidly taken up by practitioners, data points from which to derive the indicators were not defined, limiting comparability across time or settings. We convened global experts to evaluate and explicitly define-for the first time-the indicators to improve comparability and support achievement of 2030 goals to improve access to safe affordable surgical and anaesthesia care globally. METHODS AND FINDINGS: The Utstein process for developing and reporting guidelines through a consensus building process was followed. In-person discussions at a 2-day meeting were followed by an iterative process conducted by email and virtual group meetings until consensus was reached. The meeting was held between June 16 to 18, 2019; discussions continued until August 2020. Participants consisted of experts in surgery, anaesthesia, and obstetric care, data science, and health indicators from high-, middle-, and low-income countries. Considering each of the 6 indicators in turn, we refined overarching descriptions and agreed upon data points needed for construction of each indicator at current time (basic data points), and as each evolves over 2 to 5 (intermediate) and >5 year (full) time frames. We removed one of the original 6 indicators (one of 2 financial risk protection indicators was eliminated) and refined descriptions and defined data points required to construct the 5 remaining indicators: geospatial access, workforce, surgical volume, perioperative mortality, and catastrophic expenditure. A strength of the process was the number of people from global institutes and multilateral agencies involved in the collection and reporting of global health metrics; a limitation was the limited number of participants from low- or middle-income countries-who only made up 21% of the total attendees. CONCLUSIONS: To track global progress towards timely access to quality SAO care, these indicators-at the basic level-should be implemented universally as soon as possible. Intermediate and full indicator sets should be achieved by all countries over time. Meanwhile, these evolutions can assist in the short term in developing national surgical plans and collecting more detailed data for research studies.

INTRODUCTION: Longer travel times are associated with increased adverse maternal and perinatal outcomes. Geospatial modelling has been increasingly used to estimate geographic proximity in emergency obstetric care. In this study, we aimed to assess the correlation between modelled and patient-reported travel times and to evaluate its clinical relevance. METHODS: Women who delivered by caesarean section in nine hospitals were followed up with home visits at 1 month and 1 year. Travel times between the location before the delivery and the facility where caesarean section was performed were estimated, based on two models (model I Ouma et al; model II Munoz et al). Patient-reported and modelled travel times were compared applying a univariable linear regression analysis, and the relation between travel time and perinatal mortality was assessed. RESULTS: The median reported travel time was 60 min, compared with 13 and 34 min estimated by the two models, respectively. The 2-hour access threshold correlated with a patient-reported travel time of 5.7 hours for model I and 1.8 hours for model II. Longer travel times were associated with transport by boat and ambulance, visiting one or two facilities before reaching the final facility, lower education and poverty. Lower perinatal mortality was found both in the group with a reported travel time of 2 hours or less (193 vs 308 per 1000 births, p<0.001) and a modelled travel time of 2 hours or less (model I: 209 vs 344 per 1000 births, p=0.003; model II: 181 vs 319 per 1000 births, p<0.001). CONCLUSION: The standard model, used to estimate geographical proximity, consistently underestimated the travel time. However, the conservative travel time model corresponded better to patient-reported travel times. The 2-hour threshold as determined by the Lancet Commission on Global Surgery, is clinically relevant with respect to reducing perinatal death, not a clear cut-off.

The 2030 Agenda for Sustainable Development and its seventeen Sustainable Development Goals were adopted by the United Nations General Assembly in 2015. It is a bold agenda for global social, environmental and economic development, with human health as a central theme. Even though substantial improvements in health have been achieved during the last decades, every year over 5 million children die, mostly from preventable causes, and 300 000 women die in conjunction with childbirth. Premature deaths from non-communicable diseases are increasing, and our ability to treat infections is under threat through widespread anti-microbial resistance. Climate change is recognized as the biggest threat to health in our time. When the world now starts to plan for how society and our health systems should be reorganized after the COVID-19 pandemic the 2030 Agenda could and should play a central role. In this context, Agenda 2030 provides an ambitious roadmap for development, with its emphasis on collaboration across borders and disciplines. The agenda is achievable but reaching its goals will require strong commitment at all levels and societal change on a large scale.

BACKGROUND: The lack of access to essential surgical care in low-income countries is aggravated by emigration of locally-trained surgical specialists to more affluent regions. Yet, the global diaspora of surgeons, obstetricians, and anesthesiologists from low-income and middle-income countries has never been fully described and compared with those who have remained in their country of origin. It is also unclear whether the surgical workforce is more affected by international migration than other medical specialists. In this study, we aimed to quantify the proportion of surgical specialists originating from low-income and middle-income countries that currently work in high-income countries. METHODS: We retrieved surgical workforce data from 48 high-income countries and 102 low-income and middle-income countries using the database of the World Health Organization Global Surgical Workforce. We then compared this domestic workforce with more granular data on the country of initial medical qualification of all surgeons, anesthesiologists, and obstetricians made available for 14 selected high-income countries to calculate the proportion of surgical specialists working abroad. RESULTS: We identified 1,118,804 specialist surgeons, anesthesiologists, or obstetricians from 102 low-income and middle-income countries, of whom 33,021 (3.0%) worked in the 14 included high-income countries. The proportion of surgical specialists abroad was greatest for the African and South East Asian regions (12.8% and 12.1%). The proportion of specialists abroad was not greater for surgeons, anesthesiologists, or obstetricians than for physicians and other medical specialists (P = .465). Overall, the countries with the lowest remaining density of surgical specialists were also the countries from which the largest proportion of graduates were now working in high-income countries (P = .011). CONCLUSION: A substantial proportion of all surgeons, anesthesiologists, and obstetricians from low-income and middle-income countries currently work in high-income countries. In addition to decreasing migration from areas of surgical need, innovative strategies to retain and strengthen the surgical workforce could involve engaging this large international pool of surgical specialists and instructors.

INTRODUCTION: Sierra Leone has the world's highest maternal mortality, partly due to low access to caesarean section. Limited data are available to guide improvement. In this study, we aimed to analyse the rate and mortality of caesarean sections in the country. METHODS: We conducted a retrospective study of all caesarean sections and all reported in-facility maternal deaths in Sierra Leone in 2016. All facilities performing caesarean sections were visited. Data on in-facility maternal deaths were retrieved from the Maternal Death Surveillance and Response database. Caesarean section mortality was defined as in-facility perioperative mortality. RESULTS: In 2016, there were 7357 caesarean sections in Sierra Leone. This yields a population rate of 2.9% of all live births, a 35% increase from 2012, with district rates ranging from 0.4% to 5.2%. The most common indications for surgery were obstructed labour (42%), hypertensive disorders (25%) and haemorrhage (22%). Ninety-nine deaths occurred during or after caesarean section, and the in-facility perioperative caesarean section mortality rate was 1.5% (median 0.7%, IQR 0-2.2). Haemorrhage was the leading cause of death (73%), and of those who died during or after surgery, 80% had general anaesthesia, 75% received blood transfusion and 22% had a uterine rupture diagnosed. CONCLUSIONS: The caesarean section rate has increased rapidly in Sierra Leone, but the distribution remains uneven. Caesarean section mortality is high, but there is wide variation. More access to caesarean sections for maternal and neonatal complications is needed in underserved areas, and expansion should be coupled with efforts to limit late presentation, to offer assisted vaginal delivery when indicated and to ensure optimal perioperative care.
RESUMO
In the Sustainable Development Goals era, there is a new awareness of the need for an integrated approach to healthcare interventions and a strong commitment to Universal Health Coverage. To achieve the goal of strengthening entire health systems, surgery, as a crosscutting treatment modality, is indispensable. For any health system strengthening exercise, baseline data and longitudinal monitoring of progress are necessary. With improved data capabilities, there are unparalleled possibilities to map out and understand systems, integrating data from many sources and sectors. Nevertheless, there is also a need to prioritize among indicators to avoid information overload and data collection fatigue. There is a similar need to define indicators and collection methodology to create standardized and comparable data. Finally, there is a need to establish data pathways to ensure clear responsibilities amongst national and international institutions and integrate surgical metrics into existing mechanisms for sustainable data collection. This is a call to collect, aggregate, and analyze global anesthesia and surgery data, with an account of existing data sources and a proposed way forward.
RéSUMé: À l'époque des objectifs du développement durable, on constate une nouvelle sensibilisation au besoin d'une approche intégrée dans les interventions en soins de santé et un fort engagement en faveur d'une couverture médicale universelle. Pour atteindre l'objectif du renforcement de systèmes entiers de santé, la chirurgie en tant que modalité thérapeutique transversale est indispensable. Pour toute activité de renforcement du système de santé, des données de référence et un suivi longitudinal des progrès sont nécessaires. Avec de meilleures données, il existe des possibilités sans équivalent de cartographier et de comprendre les systèmes, en intégrant des données provenant de multiples sources et secteurs. Néanmoins, il est également nécessaire de prioriser les indicateurs pour éviter une surcharge d'informations et une fatigue dans la collecte des données. Il existe un besoin similaire de définition des indicateurs et de la méthodologie de collecte afin de créer des données standardisées et comparables. Enfin, il est nécessaire d'établir des cheminements de données pour garantir des responsabilités claires entre les institutions nationales et internationales et intégrer les paramètres chirurgicaux dans les mécanismes existants pour une collecte durable des données. Ceci est un appel à la collecte, au regroupement et à l'analyse de données globales en anesthésie et en chirurgie avec un compte rendu des sources de données existantes et une proposition d'avancée.

OBJECTIVE: We endeavored to create a comprehensive course in global surgery involving multinational exchange. DESIGN: The course involved 2 weeks of didactics, 2 weeks of clinical rotations in a low-resource setting and 1 week for a capstone project. We evaluated our success through knowledge tests, surveys of the students, and surveys of our Zimbabwean hosts. SETTING: The didactic portions were held in Sweden, and the clinical portion was primarily in Harare with hospitals affiliated with the University of Zimbabwe. PARTICIPANTS: Final year medical students from Lund University in Sweden, Harvard Medical School in the USA and the University of Zimbabwe all participated in didactics in Sweden. The Swedish and American students then traveled to Zimbabwe for clinical work. The Zimbabwean students remained in Sweden for a clinical experience. RESULTS: The course has been taught for 3 consecutive years and is an established part of the curriculum at Lund University, with regular participation from Harvard Medical School and the University of Zimbabwe. Participants report significant improvements in their physical exam skills and their appreciation of the needs of underserved populations, as well as confidence with global surgical concepts. Our Zimbabwean hosts thought the visitors integrated well into the clinical teams, added value to their own students' experience and believe that the exchange should continue despite the burden associated with hosting visiting students. CONCLUSIONS: Here we detail the development of a course in global surgery for medical students that integrates didactic as well as clinical experiences in a low-resource setting. The course includes a true multilateral exchange with students from Sweden, the United States and Zimbabwe participating regularly. We hope that this course might serve as a model for other medical schools looking to establish courses in this burgeoning field.

BACKGROUND: Club foot is a common congenital deformity affecting 150â 000-200â 000 children every year. Untreated patients end up walking on the side or back of the affected foot, with severe social and economic consequences. Club foot is highly treatable by the Ponseti method, a non-invasive technique that has been described as highly suitable for use in resource-limited settings. To date, there has been no evaluation of its cost-effectiveness ratio, defined as the cost of averting one disability-adjusted life year (DALY), a composite measure of the impact of premature death and disability. In this study, we aimed to calculate the average cost-effectiveness ratio of the Ponseti method for correcting club foot in sub-Saharan Africa. METHODS: Using data from 12 sub-Saharan African countries provided by the international non-profit organisation CURE Clubfoot, which implements several Ponseti treatment programmes around the world, we estimated the average cost of the point-of-care treatment for club foot in these countries. We divided the cost of treatment with the average number of DALYs that can be averted by the Ponseti treatment, assuming treatment is successful in 90% of patients. RESULTS: We found the average cost of the Ponseti treatment to be US$167 per patient. The average number of DALYs averted was 7.42, yielding a cost-effectiveness ratio of US$22.46 per DALY averted. To test the robustness of our calculation different variables were used and these yielded a cost range of US$5.28-29.75. This is less than a tenth of the cost of many other treatment modalities used in resource-poor settings today. CONCLUSIONS: The Ponseti method for the treatment of club foot is cost-effective and practical in a low-income country setting. These findings could be used to raise the priority for implementing Ponseti treatment in areas where patients are still lacking access to the life-changing intervention.
RESUMO
Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, affordable, or timely surgery. This Commission on global cancer surgery, building on Global Surgery 2030, has examined the state of global cancer surgery through an analysis of the burden of surgical disease and breadth of cancer surgery, economics and financing, factors for strengthening surgical systems for cancer with multiple-country studies, the research agenda, and the political factors that frame policy making in this area. We found wide equity and economic gaps in global cancer surgery. Many patients throughout the world do not have access to cancer surgery, and the failure to train more cancer surgeons and strengthen systems could result in as much as US $6.2 trillion in lost cumulative gross domestic product by 2030. Many of the key adjunct treatment modalities for cancer surgery--e.g., pathology and imaging--are also inadequate. Our analysis identified substantial issues, but also highlights solutions and innovations. Issues of access, a paucity of investment in public surgical systems, low investment in research, and training and education gaps are remarkably widespread. Solutions include better regulated public systems, international partnerships, super-centralisation of surgical services, novel surgical clinical trials, and new approaches to improve quality and scale up cancer surgical systems through education and training. Our key messages are directed at many global stakeholders, but the central message is that to deliver safe, affordable, and timely cancer surgery to all, surgery must be at the heart of global and national cancer control planning.

BACKGROUND: Billions of people are without access to surgical care, in part because of the inequitable distribution of the surgical workforce. Drawing on recently collected data for the number of surgeons, anaesthesiologists, and obstetricians worldwide, we sought to show their global maldistribution by identifying thresholds of surgical workforce densities, and by calculating the number of additional providers needed to reach those thresholds. METHODS: From the WHO Global Surgical Workforce Database, national data for the number of specialist surgeons, anaesthesiologists, and obstetricians per 100 000 population (density) were compared with the number of maternal deaths per 100â000 live births (maternal mortality ratio; MMR) in WHO member countries. A regression line was fit between density of specialist surgeons, anaesthesiologists, and obstetricians and the logarithm of MMR, and we explored the correlation for an upper and a lower density threshold. Based on previous estimates of the global volume of surgical procedures, a global average productivity per specialist was derived. We then multiplied the average productivity with the derived upper and lower threshold densities, and compared these numbers to previously estimated global need of surgical procedures (4664 procedures per 100â000 population). Finally, the numbers of additional providers needed to reach the thresholds in countries with a density below the respective threshold were calculated. FINDINGS: Each 10-unit increase in density of surgeons, anaesthesiologists, and obstetricians, corresponded to a 13·1% decrease in MMR (95% CI 11·3-14·8). We saw particularly steep improvements in MMR from 0 to roughly 20 per 100â000 population. Above roughly 40 per 100â000 population, higher density was associated with relatively smaller improvements in MMR. These arbitrary thresholds of 20 and 40 specialists per 100â000 corresponded with a volume of surgery of 2917 and 5834 procedures per 100â000 population, respectively, and were symmetrically distributed around the estimated global need of 4664 surgical procedures per 100â000 population. Our density thresholds are slightly higher than the current average in lower-middle income countries (16 per 100â000) and upper-middle-income countries (38 per 100â000), respectively. To reach the threshold of at least 20 per 100â000 in each country today, another 440â231 (IQR 438â900-443â245) providers would be needed. To reach 40 per 100â000, 1â110â610 (IQR 1â095â376-1â183â525) providers would be needed. INTERPRETATION: Assuming uniform productivity, a global surgical workforce between 20 and 40 per 100â000 would suffice to provide the world's missing surgical procedures. We concede that causality cannot be implied, but our results suggest that countries with a workforce density above certain thresholds have better health outcomes. Although the thresholds cannot be interpreted as a minimum standard, they are useful to characterise the global surgical workforce and its deficits. Such thresholds could also be used as markers for health system capacity. FUNDING: None.
