Task-sharing or public finance for the expansion of surgical access in rural Ethiopia: an extended cost-effectiveness analysis

Assessing Ethiopia's surgical capacity in light of global surgery 2030 initiatives: Is there progress in the past decade?

Background

Surgical, anesthetic, and obstetric (SAO) care plays a crucial role in global health, recognized by the World Health Organization (WHO) and The Lancet Commission on Global Surgery (LCoGS). LCoGS outlines six indicators for integrating SAO services into a country's healthcare system through National Surgical Obstetrics and Anesthesia Plans (NSOAPs). In Ethiopia, surgical services progress lacks evaluation. This study assesses current Ethiopian surgical capacity using the LCoGS NSOAPs framework.

Methods

We conducted a narrative review of published literature on critical LCoGS NSAOPs metrics to extract information on key domains; service delivery, workforce, infrastructure, finance, and information management.

Results

Ethiopia's surgical services face challenges, including a low surgical volume (43) and a scarcity of specialist SOA physicians (0.5) per 100,000 population. Over half of Ethiopians reside outside the 2-hour radius of surgery-ready hospitals, and 98 % face surgery-related impoverished expenditures. Lacking the LCoGS-recommended SOA reporting systems, approximately 44 % of facilities exist for handling bellwether procedures. Despite the prevalence of essential surgeries, primary district hospitals have limited operative infrastructures, resulting in disparities in the surgical landscape. Most surgery-ready facilities are concentrated in cities, leaving Ethiopia's 80 % rural population with inadequate access to surgical care.

Conclusion

Ethiopia's surgical capacity falls below LCoGS NSOAPs recommendations, with challenges in infrastructure, personnel, and data retrieval. Critical measures include scaling up access, workforce, public insurance, and information management to enhance SAO services. Ethiopia pioneered in Sub-Saharan Africa by establishing Saving Lives Through Safe Surgery (SaLTS) in response to NSOAPs, but progress lags behind LCoGS recommendations.

Task Shifting and Task Sharing to Strengthen the Surgical Workforce in Sub-Saharan Africa: A Systematic Review of the Existing Literature

BACKGROUND

A major constraint to surgical care delivery in low-resource settings is inadequate workforce availability. Surgical task shifting (TShifting) and task sharing (TSharing), in which non-surgeon clinicians (NSCs) are trained to perform select surgical procedures, have been proposed as one solution. However, patterns of safety and efficacy of surgical TShifting/TSharing are not well-established. This study aims to summarize the current literature and assess clinical outcomes and impact of surgical TShifting/TSharing in sub-Saharan Africa.

METHODS

A two-tiered systematic, PRISMA-adherent literature review of surgical TShifting/TSharing in sub-Saharan Africa was conducted. Collected data included healthcare settings; types of surgeries performed; attitudes toward NSCs; and categories, training, capacity, clinical outcomes, safety, retention, cost-effectiveness, and supervision of NSCs. A random effects meta-analysis of morbidity and mortality rates between NSCs and surgeons was conducted.

RESULTS

Among the 659 abstracts screened, 31 studies met inclusion criteria and were integrated in the final analysis. Eighteen studies (58%) report on the capacity and aptitude of NSCs, 16 (52%) on clinical outcomes and safety, and seven (23%) on attitudes. NSCs performed 1999 (61%) of 3304 total surgical cases studied. The most common operations reported were hernia repair (n = 12, 57%), acute abdominal (n = 12, 57%), and orthopedic procedures (n = 6, 29%). No differences were found between NSC and surgeon case morbidity [315 (16%) vs. 224 (17%); p > 0.05] and mortality [44 (2.2%) vs. 33 (2.5%); p > 0.05] rates.

CONCLUSION

NSCs are increasingly performing surgical tasks in regions of sub-Saharan Africa deficient in trained surgeons and appear to have non-inferior safety outcomes in select programs.

Bioethical Implications of Vulnerability and Politics for Healthcare in Ethiopia and The Ways Forward

Vulnerability and politics are among the relevant and key topics of discussion in the Ethiopian healthcare context. Attempts by the formal bioethics structure in Ethiopia to deliberate on ethical issues relating to vulnerability and politics in healthcare have been limited, even though the informal analysis of bioethical issues has been present in traditional Ethiopian communities. This is reflected in religion, social values, and local moral underpinnings. Thus, the aim of this paper is to discuss the bioethical implications of vulnerability and politics for healthcare in Ethiopia and to suggest possible ways forward. First, we will briefly introduce what has been done to develop bioethics as a field in Ethiopia and what gaps remain concerning its implementation in healthcare practice. This will give a context for our second and main task - analyzing the healthcare challenges in relation to vulnerability and politics and discussing their bioethical implications. In doing so, and since these two concepts are intrinsically broad, we demarcate their scope by focusing on specific issues such as poverty, gender, health governance, and armed conflicts. Lastly, we provide suggestions for the ways forward.

Cost-Effectiveness Analysis of Inguinal Hernia Repair With Mesh Performed by Surgeons and Medical Doctors in Ghana

OBJECTIVES

Task-sharing is the pragmatic sharing of tasks between providers with different levels of training. To our knowledge, no study has examined the cost-effectiveness of surgical task-sharing of hernia repair in a low-resource setting. This study has aimed to evaluate and compare the cost-effectiveness of mesh repair performed by Ghanaian surgeons and medical doctors (MDs) following a standardized training program.

METHODS

This cost-effectiveness analysis included data for 223 operations on adult men with primary reducible inguinal hernia. Cost per surgery was calculated from the healthcare system perspective. Disability weights were calculated using pre- and postoperative pain scores and benchmarks from the Global Burden of Disease Study 2017.

RESULTS

The mean cost/disability-adjusted life-year (DALY) averted in the surgeon group was 444.9 United States dollars (USD) (95% confidence interval [CI] 221.2-668.5) and 278.9 USD (95% CI 199.3-358.5) in the MD group (P = .168), indicating that the operation is very cost-effective when performed by both providers. The incremental cost/DALY averted showed that task-sharing with MDs is also very cost-effective (95% bootstrap CI -436.7 to 454.9). The analysis found that increasing provider salaries is cost-effective if productivity remains high. When only symptomatic cases were analyzed, the mean cost/DALY averted reduced to 232.0 USD (95% CI 17.1-446.8) for the surgeon group and 129.7 USD (95% CI 79.6-179.8) for the MD group (P = .348), and the incremental cost/DALY averted increased by 45% but remained robust.

CONCLUSIONS

Elective inguinal hernia repair with mesh performed by Ghanaian surgeons and MDs is a low-cost procedure and very cost-effective in the context of the study. To maximize cost-effectiveness, symptomatic patients should be prioritized over asymptomatic patients and a high level of productivity should be maintained.

A Systematic Review of Scope and Quality of Health Economic Evaluations Conducted in Ethiopia

There has been an increased interest in health technology assessment and economic evaluations for health policy in Ethiopia over the last few years. In this systematic review, we examined the scope and quality of healthcare economic evaluation studies in Ethiopia. We searched seven electronic databases (PubMed/MEDLINE, EMBASE, PsycINFO, CINHAL, Econlit, York CRD databases and CEA Tufts) from inception to May 2021 to identify published full health economic evaluations of a health-related intervention or programme in Ethiopia. This was supplemented with forward and backward citation searches of included articles, manual search of key government websites, the Disease Control Priorities-Ethiopia project and WHO-CHOICE programme. The quality of reporting of economic evaluations was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. The extracted data were grouped into subcategories based on the subject of the economic evaluation, organized into tables and reported narratively. This review identified 34 full economic evaluations conducted between 2009 and 2021. Around 14 (41%) of studies focussed on health service delivery, 8 (24%) on pharmaceuticals, vaccines and devices, and 4 (12%) on public-health programmes. The interventions were mostly preventive in nature and focussed on communicable diseases (n = 19; 56%) and maternal and child health (n = 6; 18%). Cost-effectiveness ratios varied widely from cost-saving to more than US $37 313 per life saved depending on the setting, perspectives, types of interventions and disease conditions. While the overall quality of included studies was judged as moderate (meeting 69% of CHEERS checklist), only four out of 27 cost-effectiveness studies characterized heterogeneity. There is a need for building local technical capacity to enhance the design, conduct and reporting of health economic evaluations in Ethiopia.

Exploring the Relationship Between Surgical Capacity and Output in Ghana: Current Capacity Assessments May Not Tell the Whole Story

OBJECTIVE

Capacity assessments serve as surrogates for surgical output in low- and middle-income countries where detailed registers do not exist. The relationship between surgical capacity and output was evaluated in Ghana to determine whether a more critical interpretation of capacity assessment data is needed on which to base health systems strengthening initiatives.

METHODS

A standardized surgical capacity assessment was performed at 37 hospitals nationwide using WHO guidelines; availability of 25 essential resources and capabilities was used to create a composite capacity score that ranged from 0 (no availability of essential resources) to 75 (constant availability) for each hospital. Data regarding the number of essential operations performed over 1 year, surgical specialties available, hospital beds, and functional operating rooms were also collected. The relationship between capacity and output was explored.

RESULTS

The median surgical capacity score was 37 [interquartile range (IQR) 29-48; range 20-56]. The median number of essential operations per year was 1480 (IQR 736-1932) at first-level hospitals; 1545 operations (IQR 984-2452) at referral hospitals; and 11,757 operations (IQR 3769-21,256) at tertiary hospitals. Surgical capacity and output were not correlated (p > 0.05).

CONCLUSIONS

Contrary to current understanding, surgical capacity assessments may not accurately reflect surgical output. To improve the validity of surgical capacity assessments and facilitate maximal use of available resources, other factors that influence output should also be considered, including demand-side factors; supply-side factors and process elements; and health administration and management factors.

Health-system-adapted data envelopment analysis for decision-making in universal health coverage

OBJECTIVE

To develop and test a method that allows an objective assessment of the value of any health policy in multiple domains.

METHODS

We developed a method to assist decision-makers with constrained resources and insufficient knowledge about a society's preferences to choose between policies with unequal, and at times opposing, effects on multiple outcomes. Our method extends standard data envelopment analysis to address the realities of health policy, such as multiple and adverse outcomes and a lack of information about the population's preferences over those outcomes. We made four modifications to the standard analysis: (i) treating the policy itself as the object of analysis, (ii) allowing the method to produce a rank-ordering of policies; (iii) allowing any outcome to serve as both an output and input; and (iv) allowing variable return to scale. We tested the method against three previously published analyses of health policies in low-income settings.

RESULTS

When applied to previous analyses, our new method performed better than traditional cost-effectiveness analysis and standard data envelopment analysis. The adapted analysis could identify the most efficient policy interventions from among any set of evaluated policies and was able to provide a rank ordering of all interventions.

CONCLUSION

Health-system-adapted data envelopment analysis allows any quantifiable attribute or determinant of health to be included in a calculation. It is easy to perform and, in the absence of evidence about a society's preferences among multiple policy outcomes, can provide a comprehensive method for health-policy decision-making in the era of sustainable development.

Cost-Effectiveness in Global Surgery: Pearls, Pitfalls, and a Checklist

INTRODUCTION

Cost-effectiveness analysis can be a powerful policy-making tool. In the two decades since the first cost-effectiveness analyses in global surgery, the methodology has established the cost-effectiveness of many types of surgery in low- and middle-income countries (LMICs). However, with the crescendo of cost-effectiveness analyses in global surgery has come vast disparities in methodology, with only 15% of studies adhering to published guidelines. This has led to results that have varied up to 150-fold.

METHODS

The theoretical basis, common pitfalls, and guidelines-based recommendations for cost-effectiveness analyses are reviewed, and a checklist to be used for cost-effectiveness analyses in global surgery is created.

RESULTS

Common pitfalls in global surgery cost-effectiveness analyses fall into five categories: the analytic perspective, cost measurement, effectiveness measurement, probability estimation, valuation of the counterfactual, and heterogeneity and uncertainty. These are reviewed in turn, and a checklist to avoid these pitfalls is developed.

CONCLUSION

Cost-effectiveness analyses, when done rigorously, can be very useful for the development of efficient surgical systems in LMICs. This review highlights the common pitfalls in these analyses and methods to avoid these pitfalls.

Bridging the human resource gap in surgical and anesthesia care in low-resource countries: a review of the task sharing literature

Task sharing, the involvement of non-specialists (non-physician clinicians or non-specialist physicians) in performing tasks originally reserved for surgeons and anesthesiologists, can be a potent strategy in bridging the vast human resource gap in surgery and anesthesia and bringing needed surgical care to the district level especially in low-resource countries. Although a common practice, the idea of assigning advanced tasks to less-specialized workers remains a subject of controversy. In order to optimize its benefits, it is helpful to understand the current task sharing landscape, its challenges, and its promise. We performed a literature review of PubMed, EMBASE, and gray literature sources for articles published between January 1, 1996, and August 1, 2016, written in English, with a focus on task sharing in surgery or anesthesia in low-resource countries. Gray literature sources are defined as articles produced outside of a peer-reviewed journal. We sought data on the nature and forms of task sharing (non-specialist cadres involved, surgical/anesthesia procedures shared, approaches to training and supervision, and regulatory and other efforts to create a supportive environment), impact of task sharing on delivery of surgical services (effect on access, acceptability, cost, safety, and quality), and challenges to successful implementation. We identified 40 published articles describing task sharing in surgery and anesthesia in 39 low-resource countries in Africa and Asia. All countries had a cadre of non-specialists providing anesthesia services, while 13 had cadres providing surgical services. Six countries had non-specialists performing major procedures, including Cesarean sections and open abdominal surgeries. While most cadres were recognized by their governments as service providers, very few had scopes of practice that included task sharing of surgery or anesthesia. Key challenges to effective task sharing include specialists' concern about safety, weak training strategies, poor or unclear career pathways, regulatory constraints, and service underutilization. Concrete recommendations are offered.

Facilitating access to surgical care through a decentralised case-finding strategy: experience in Madagascar

Over two-thirds of the world’s population lack access to surgical care. Non-governmental organisation’s providing free surgeries may overcome financial barriers, but other barriers to care still exist. This analysis paper discusses two different case-finding strategies in Madagascar that aimed to increase the proportion of poor patients, women and those for whom multiple barriers to care exist. From October 2014 to June 2015, we used a centralised selection strategy, aiming to find 70% of patients from the port city, Toamasina, and 30% from the national capital and two remote cities. From August 2015 to June 2016, a decentralised strategy was used, aiming to find 30% of patients from Toamasina and 70% from 11 remote locations, including the capital. Demographic information and self-reported barriers to care were collected. Wealth quintile was calculated for each patient using a combination of participant responses to asset-related and demographic questions, and publicly available data. A total of 2971 patients were assessed. The change from centralised to decentralised selection resulted in significantly poorer patients undergoing surgery. All reported barriers to prior care, except for lack of transportation, were significantly more likely to be identified in the decentralised group. Patients who identified multiple barriers to prior surgical care were less likely to be from the richest quintile (p=0.037) and more likely to be in the decentralised group (p=0.046). Our country-specific analysis shows that decentralised patient selection strategies may be used to overcome barriers to care and allow patients in greatest need to access surgical care.

Laparoscopic Versus Open Cholecystectomy: A Cost-Effectiveness Analysis at Rwanda Military Hospital

BACKGROUND

Laparoscopic 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.

METHODS

A 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.

RESULTS

The laparoscopic and open cholecystectomy costs and effectiveness values were $2664.47 with 0.87 quality-adjusted life years (QALYs) and $2058.72 with 0.75 QALYs, respectively. The incremental cost-effectiveness ratio for laparoscopic over open cholecystectomy was $4946.18. Results are sensitive to the initial laparoscopic equipment investment and number of cases performed annually but robust to other parameters. The laparoscopic intervention is more cost-effective with investment costs less than $91,979, greater than 65 cases annually, or at willingness-to-pay (WTP) thresholds greater than $3975/QALY.

CONCLUSIONS

At 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.

Global Surgery 2030: a roadmap for high income country actors

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 world's 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.
