    Obstructed Labor and Caesarean Delivery: The Cost and Benefit of Surgical Intervention

    (Public Library of Science, 2012) Alkire, Blake; Vincent, Jeffrey R.; Burns, Christy Turlington; Metzler, Ian Scott; Farmer, Paul; Meara, John

    Background: Although advances in the reduction of maternal mortality have been made, up to 273,000 women will die this year from obstetric etiologies. Obstructed labor (OL), most commonly treated with Caesarean delivery, has been identified as a major contributor to global maternal morbidity and mortality. We used economic and epidemiological modeling to estimate the cost per disability-adjusted life-year (DALY) averted and benefit-cost ratio of treating OL with Caesarean delivery for 49 countries identified as providing an insufficient number of Caesarean deliveries to meet demand. Methods and Findings Using publicly available data and explicit economic assumptions, we estimated that the cost per DALY (3,0,0) averted for providing Caesarean delivery for OL ranged widely, from $251 per DALY averted in Madagascar to $3,462 in Oman. The median cost per DALY averted was $304. Benefit-cost ratios also varied, from 0.6 in Zimbabwe to 69.9 in Gabon. The median benefit-cost ratio calculated was 6.0. The main limitation of this study is an assumption that lack of surgical capacity is the main factor responsible for DALYs from OL. Conclusions: Using the World Health Organization's cost-effectiveness standards, investing in Caesarean delivery can be considered “highly cost-effective” for 48 of the 49 countries included in this study. Furthermore, in 46 of the 49 included countries, the benefit-cost ratio was greater than 1.0, implying that investment in Caesarean delivery is a viable economic proposition. While Caesarean delivery alone is not sufficient for combating OL, it is necessary, cost-effective by WHO standards, and ultimately economically favorable in the vast majority of countries included in this study.

    Unilateral Cleft Lip and Nasal Repair: Techniques and Principles

    (Tehran University of Medical Sciences, 2011) Meara, John; Andrews, Brian T.; Ridgway, Emily B.; Raisolsadat, Mohammad-Ali; Hiradfar, Mehran

    The Mashhad University of Medical Sciences and the Sheikh Hospital in Mashhad sponsored a Cleft Lip and Palate Workshop 30 April – 1 May 2009. During the Workshop, 6 surgical cases were performed and televised live to the audience attending the conference. Two of those cases were unilateral cleft lip repairs. The surgical technique used to repair these patients by the primary author (JGM) is a hybrid technique. It has evolved over the last decade as a result of prior surgical literature as well as first hand observation of various surgical colleagues. The following manuscript describes the surgical technique used at the Cleft Workshop in a step-wise or atlas-like fashion. The technique portion of the paper describes the repair of the unilateral cleft lip and nasal deformity in roughly the order the first author typically performs the procedure. More importantly, the final section of the paper details the principles that form the foundation for the techniques described.

    A Systematic Review of Barriers to Breast Cancer Care in Developing Countries Resulting in Delayed Patient Presentation

    (Hindawi Publishing Corporation, 2012) Sharma, Ketan; Costas-Chavarri, Ainhoa; Shulman, Lawrence; Meara, John

    Background: Within the developing world, many personal, sociocultural, and economic factors cause delayed patient presentation, a prolonged interval from initial symptom discovery to provider presentation. Understanding these barriers to care is crucial to optimizing interventions that pre-empt patient delay. Methods: A systematic review was conducted querying: PubMed, Embase, Web of Science, CINAHL, Cochrane Library, J East, CAB, African Index Medicus, and LiLACS. Of 763 unique abstracts, 122 were extracted for full review and 13 included in final analysis. Results: Studies posed variable risks of bias and produced mixed results. There is strong evidence that lower education level and lesser income status contribute to patient delay. There is weaker and, sometimes, contradictory evidence that other factors may also contribute. Discussion. Poverty emerges as the underlying common denominator preventing earlier presentation in these settings. The evidence for sociocultural variables is less strong, but may reflect current paucity of high-quality research. Conflicting results may be due to heterogeneity of the developing world itself. Conclusion: Future research is required that includes patients with and without delay, utilizes a validated questionnaire, and controls for potential confounders. Current evidence suggests that interventions should primarily increase proximal and affordable healthcare access and secondarily enhance breast cancer awareness, to productively reduce patient delay.

    Funding allocation to surgery in low and middle-income countries: a retrospective analysis of contributions from the USA

    (BMJ Publishing Group, 2015) Gutnik, Lily; Dieleman, Joseph; Dare, Anna J; Ramos, Margarita S; Riviello, Robert; Meara, John; Yamey, Gavin; Shrime, Mark

    Objective: The funds available for global surgical delivery, capacity building and research are unknown and presumed to be low. Meanwhile, conditions amenable to surgery are estimated to account for nearly 30% of the global burden of disease. We describe funds given to these efforts from the USA, the world's largest donor nation. Design: Retrospective database review. US Agency for International Development (USAID), National Institute of Health (NIH), Foundation Center and registered US charitable organisations were searched for financial data on any organisation giving exclusively to surgical care in low and middle income countries (LMICs). For USAID, NIH and Foundation Center all available data for all years were included. The five recent years of financial data per charitable organisation were included. All nominal dollars were adjusted for inflation by converting to 2014 US dollars. Setting: USA. Participants: USAID, NIH, Foundation Center, Charitable Organisations. Primary and secondary outcome measures Cumulative funds appropriated to global surgery. Results: 22 NIH funded projects (totalling $31.3 million) were identified, primarily related to injury and trauma. Six relevant USAID projects were identified—all obstetric fistula care totalling $438 million. A total of $105 million was given to universities and charitable organisations by US foundations for 12 different surgical specialties. 95 US charitable organisations representing 14 specialties totalled revenue of $2.67 billion and expenditure of $2.5 billion. Conclusions and relevance Current funding flows to surgical care in LMICs are poorly understood. US funding predominantly comes from private charitable organisations, is often narrowly focused and does not always reflect local needs or support capacity building. Improving surgical care, and embedding it within national health systems in LMICs, will likely require greater financial investment. Tracking funds targeting surgery helps to quantify and clarify current investments and funding gaps, ensures resources materialise from promises and promotes transparency within global health financing.

    An Opportunity for Diagonal Development in Global Surgery: Cleft Lip and Palate Care in Resource-Limited Settings

    (Hindawi Publishing Corporation, 2012) Patel, Pratik Bharat; Hoyler, Marguerite Mcmillan; Maine, Rebecca; Hughes, Christopher D.; Hagander, Lars; Meara, John

    Global cleft surgery missions have provided much-needed care to millions of poor patients worldwide. Still, surgical capacity in low- and middle-income countries is generally inadequate. Through surgical missions, global cleft care has largely ascribed to a vertical model of healthcare delivery, which is disease specific, and tends to deliver services parallel to, but not necessarily within, the local healthcare system. The vertical model has been used to address infectious diseases as well as humanitarian emergencies. By contrast, a horizontal model for healthcare delivery tends to focus on long-term investments in public health infrastructure and human capital and has less often been implemented by humanitarian groups for a variety of reasons. As surgical care is an integral component of basic healthcare, the plastic surgery community must challenge itself to address the burden of specific disease entities, such as cleft lip and palate, in a way that sustainably expands and enriches global surgical care as a whole. In this paper, we describe a diagonal care delivery model, whereby cleft missions can enrich surgical capacity through integration into sustainable, local care delivery systems. Furthermore, we examine the applications of diagonal development to cleft care specifically and global surgical care more broadly.

    The Haiti Breast Cancer Initiative: Initial Findings and Analysis of Barriers-to-Care Delaying Patient Presentation

    (Hindawi Publishing Corporation, 2013) Sharma, Ketan; Costas-Chavarri, Ainhoa; Damuse, Ruth; Hamiltong-Pierre, Jean; Pyda, Jordan; Ong, Cecilia T.; Shulman, Lawrence N.; Meara, John

    Background. In Haiti, breast cancer patients present at such advanced stages that even modern therapies offer modest survival benefit. Identifying the personal, sociocultural, and economic barriers-to-care delaying patient presentation is crucial to controlling disease. Methods. Patients presenting to the Hôpital Bon Sauveur in Cange were prospectively accrued. Delay was defined as 12 weeks or longer from initial sign/symptom discovery to presentation, as durations greater than this cutoff correlate with reduced survival. A matched case-control analysis with multivariate logistic regression was used to identify factors predicting delay. Results. Of N = 123 patients accrued, 90 (73%) reported symptom-presentation duration and formed the basis of this study: 52 patients presented within 12 weeks of symptoms, while 38 patients waited longer than 12 weeks. On logistic regression, lower education status (OR = 5.6, P = 0.03), failure to initially recognize mass as important (OR = 13.0, P < 0.01), and fear of treatment cost (OR = 8.3, P = 0.03) were shown to independently predict delayed patient presentation. Conclusion. To reduce stage at presentation, future interventions must educate patients on the recognition of initial breast cancer signs and symptoms and address cost concerns by providing care free of charge and/or advertising that existing care is already free.

    Health and Economic Benefits of Improved Injury Prevention and Trauma Care Worldwide

    (Public Library of Science, 2014) Kotagal, Meera; Agarwal-Harding, Kiran; Mock, Charles; Quansah, Robert; Arreola-Risa, Carlos; Meara, John

    Objectives: Injury is a significant source of morbidity and mortality worldwide, and often disproportionately affects younger, more productive members of society. While many have made the case for improved injury prevention and trauma care, health system development in low- and middle-income countries is often limited by resources. This study aims to determine the economic benefit of improved injury prevention and trauma care in low- and middle-income countries. Methods: This study uses existing data on injury mortality worldwide from the 2010 Global Burden of Disease Study to estimate the number of lives that could be saved if injury mortality rates in low- and middle-income countries could be reduced to rates in high-income countries. Using economic modeling – through the human capital approach and the value of a statistical life approach – the study then demonstrates the associated economic benefit of these lives saved. Results: 88 percent of injury-related deaths occur in low- and middle-income countries. If injury mortality rates in low- and middle-income countries were reduced to rates in high-income countries, 2,117,500 lives could be saved per year. This would result in between 49 million and 52 million disability adjusted life years averted per year, with discounting and age weighting. Using the human capital approach, the associated economic benefit of reducing mortality rates ranges from $245 to $261 billion with discounting and age weighting. Using the value of a statistical life approach, the benefit is between 758 and 786 billion dollars per year. Conclusions: Reducing injury mortality in low- and middle-income countries could save over 2 million lives per year and provide significant economic benefit globally. Further investments in trauma care and injury prevention are needed.

    Assessing the Brazilian surgical system with six surgical indicators: a descriptive and modelling study

    (BMJ, 2017) Massenburg, Benjamin B; Saluja, Saurabh; Jenny, Hillary; Raykar, Nakul; Ng-Kamstra, Josh; Guilloux, Aline G A; Scheffer, Mário C; Meara, John; Alonso, Nivaldo; Shrime, Mark

    Background: Brazil boasts a health scheme that aspires to provide universal coverage, but its surgical system has rarely been analyzed. In an effort to strengthen surgical systems worldwide, the Lancet Commission on Global Surgery proposed collection of six standardized indicators: two-hour access to surgery, surgical workforce density, surgical volume, perioperative mortality rate (POMR), and protection against impoverishing and catastrophic expenditure. This study aims to characterize the Brazilian surgical health system with these newly devised indicators while gaining understanding on the complexity of the indicators themselves. Methods: Using Brazil’s national healthcare database, commonly reported healthcare variables were used to calculate or simulate the six surgical indicators. Access to surgery was calculated using hospital locations, surgical workforce density was calculated using locations of surgeons, anesthesiologists and obstetricians (SAO), and surgical volume and POMR were identified with surgical procedure codes. The rates of protection against impoverishing and catastrophic expenditure were modelled using cost of inpatient hospitalization and a gamma distribution of incomes based on GINI and GDP/capita. Findings: In 2014, SAO density is 34·7/100,000 population, surgical volume is 4,433 procedures/100,000 people and POMR is 1·71%. 79·4% of surgical patients are protected against impoverishing expenditure and 84·6% were protected against catastrophic expenditure due to surgery each year. Two-hour access to surgery was not able to be calculated from national health data, but a proxy measure suggested that 97·2% of the population has two-hour access to a hospital that may be able to provide surgery. Geographic disparities were seen in all indicators. Interpretation: Brazil‘s public surgical system meets several key benchmarks. Geographic disparities, however, are substantial and raise concerns of equity. Policies should focus on stimulating appropriate geographic allocation of the surgical workforce. In some cases, where benchmarks for each indicator are met, supplemental analysis can further inform our understanding of health systems. This measured and systematic evaluation of surgical systems should be encouraged for all nations seeking to better understand their surgical systems. Funding: There was no funding for this study.
