Cost-Effectiveness of Ingunial Hernia Surgery in Northwestern Ecuador

Cost-Effectiveness of Pediatric Hand International Medical Missions

PURPOSE

Limited access and resources in low- and middle-income countries leave many individuals deprived of medical care. Surgical mission trips offer a solution to provide sound surgical care to underserved areas but require a sizable financial support. Previous analyses of such trips have not included values of donated supplies and costs borne by the host country. We hypothesized that the orthopedic mission trips, utilizing the World Pediatric Project (WPP) model, can be executed in a cost-effective manner according to the World Health Organization thresholds even when considering cost to the organizations and host country.

METHODS

World Pediatric Project records for the most recent pediatric upper extremity orthopedic mission trips of 2016, 2018, and 2019 were obtained. Cost estimates were based on documentation from each of the mission trips. Total costs included the costs borne by the WPP, estimates of the value of donated supplies, and costs borne by the host country. The cost-effectiveness of the surgical mission trips was determined by the total cost and potential benefit of performing the orthopedic surgeries using disability-adjusted life years averted.

RESULTS

Three separate mission trips to St. Vincent and the Grenadines were analyzed. Forty-five pediatric patients had received surgical care. The cost was calculated to be $431.50 per disability-adjusted life years averted when only the WPP costs are considered; including donated supplies and cost borne by the host country in the total cost, the cost was $6898.10 per disability-adjusted life years averted. After comparing the cost values to the per capita gross domestic product of St. Vincent and the Grenadines, $7,463.54, the WPP mission trips were determined to be cost-effective according to the WHO-CHOICE thresholds in all 5 categories.

CONCLUSIONS

Orthopedic medical mission trips can provide cost-effective surgical treatments for the upper extremity even when the costs to the organization and host country and trip donations are considered.

Benefica chirurgia. A global surgery project focusing on hernia surgery

BACKGROUND

The aim of international health cooperation projects is to alleviate the deficiencies in the area of health in low resource settings. Hernia surgery is a procedure that is well suited to these missions, due to its low morbidity, the fact that it can be performed on an outpatient basis, and the improvement in quality of life that it provides.

OBJECTIVE

To describe the results of Benefica Chirurgia (BC), a Spanish non-profit humanitarian association in hernia pathology.

METHODS

Five one-week surgical campaigns were carried out in Ecuador between 2015 and 2019, involving anesthetists, general and pediatric surgeons. Surgical and medical equipment was provided and transported by BC. ASA I/II patients underwent surgery.

RESULTS

Surgery was performed on 240 patients with hernia pathology on 27 days. Sixty-three per cent of patients were male and the mean age was 48.2 years (range: 1-83). Hernia location was inguinal in 113 patients, umbilical in 101, and other in 26. The anesthetic technique used was spinal in 185 patients (77.1%), local plus intravenous sedation in 31 (12.9%), and general in 24 (10%). The surgical technique used was hernioplasty in 191 patients, herniorrhaphy in 31, incisional hernia repair in 15 and herniotomy in three. Surgery was performed on an outpatient basis in 98.4% of cases. Morbidity was 2%. Long-term postoperative evaluation is very complex.

CONCLUSION

These campaigns make a significant contribution to health in low resource settings and provide great personal satisfaction for those involved. Standards achieved in the immediate postoperative period were similar to those obtained at the surgeons' centers in Europe. However, it is difficult to establish the rates of recurrence and chronic pain.

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.

Cost-effectiveness of paediatric surgery: an economic evaluation of World Paediatric Project surgical interventions in St. Vincent and the Grenadines (2002–2019)

Objectives

The purpose of this study is to examine the cost-effectiveness of six types of surgical interventions as part of a sustained paediatric surgical programme in St.Vincent and the Grenadines from 2002 to 2019.

Design

In this economic model, six paediatric surgical interventions (ophthalmic, orthopaedic, plastic, general, urology, neurosurgery) were compared with no surgery in a deterministic cost-effectiveness model. We assessed health benefits as averted disability-adjusted life-years (DALYs). Costs were included from the programme perspective and measured using standard micro-costing methods. Incremental cost-effectiveness ratios (ICERs) were calculated for each type of surgical intervention. Interventions with ICERs of <50% of gross domestic product (GDP) per capita were considered cost-effective. Costs are reported in 2019 US$. Univariate sensitivity analyses were conducted to assess the effect of uncertainty.

Results

The average cost per procedure was US$16 685 (range: US$9791.78–US$72 845.76). The cumulative discounted 18-year health impact was 5815 DALYs averted with a cost per DALY averted of US$2622. Most paediatric surgical interventions were cost-effective, yielding cost per DALY estimates less than 50% of GDP per capita of St. Vincent and the Grenadines. When undiscounted, only orthopaedic surgeries had cost per DALY more than 50% GDP per capita. When considering discounting, orthopaedic and urology surgeries exceeded the adopted threshold for cost-effectiveness.

Conclusions

We found that short-term, recurrent surgical interventions could yield substantial economic benefits in this limited resource setting. This research indicates that investment in paediatric surgical interventions is cost-effective for the majority of specialties. These findings are of clinical significance given the large burden of disease attributable to surgically treatable diseases. This work demonstrates that scaling up dedicated surgical programmes for children is a cost-effective and essential component to improve paediatric health.

A Systematic Review of Orthopedic Global Outreach Efforts Based on WHO-CHOICE Thresholds

Injury and musculoskeletal disorders are a major cause of death, disability, and decreased quality of life in developing countries. Thus, understanding the cost-effectiveness of orthopedic care in low- and middle-income countries may help to guide future outreach. A systematic review was conducted on the literature available on the cost-effectiveness of surgical trips that provided orthopedic-related care and extracted data regarding the cost-effectiveness of the orthopedic-related interventions. The cost-effectiveness of the interventions was determined using the WHO-CHOICE thresholds.

Minimally invasive inguinal hernia repair is superior to open: a national database review

PURPOSE

Many publications have focused on single-surgeon or single-center data, comparing surgical approach in inguinal hernia repair. This study evaluated outcomes in patients who underwent open (OIHR), laparoscopic (LIHR) or robotic (RIHR) inguinal hernia repair using a national database.

METHODS

The Vizient clinical database was queried using ICD-9 and ICD-10 procedure and diagnosis codes for RIHR, LIHR, and OIHR from 2013 to 2017. Elective procedures classified as minor or moderate risk severity were included. Complications, 30-day readmission, mortality, LOS, and intra-hospital opiate utilization were analyzed using IBM SPSS v.23.0.

RESULTS

3547 patients (OIHR: N = 2413, LIHR: N = 540, RIHR: N = 594) were included in the study. Majority were male (OIHR 84.1%, LIHR 80.4%, RIHR 95.3%), ≥ 51 years (OIHR 81.5%, LIHR 81.7%, RIHR 95.3%), and Caucasian (OIHR 75.7%, LIHR 77.0%, RIHR 81.5%). RIHR had the least overall complications (0.67%) compared to LIHR (4.44%) and OIHR (3.85%), p < 0.05. OIHR had the highest postoperative infection rate (8.33%), versus LIHR (0.56%) and RIHR (0.0%), p < 0.05. OIHR had longer length of stay (3.57 ± 4.1 days) when compared to both groups (LIHR 2.2 ± 2.13 days, RIHR 1.75 ± 1.62 days), p < 0.001. OIHR had higher 30-day readmission rates (3.61%) compared to RIHR (0.84%), p = 0.001. Mortality was similar between groups (OIHR 0.21%, LIHR 0.19%, RIHR 0.17%), p = 0.081. Opiate use was higher with OIHR (96.0%), compared to both LIHR (93.1%), and RIHR (93.8%), p = 0.004.

CONCLUSION

RIHR outcomes were improved compared to OIHR or LIHR. OIHR had the highest rate of opiate use, there was no difference between LIHR and RIHR. Further studies are needed to determine the role of RIHR and to assess whether surgeon or patient selection contributes to outcomes.

Cost-Effectiveness Analysis of Mesh Repair for Inguinal Hernia During a Humanitarian Surgical Mission in Rural Nigeria

Background:

Humanitarian short-term surgery missions remain under debate, even though the proportion of the burden of surgical diseases around the world that could be treated based on surgery is constantly rising. The primary objective of this study was to prove the cost-effectiveness (CE) of a hernia repair–teaching mission in the rural setting of Nigeria.

Methods:

We present a CE analysis (CEA) of a 2-week surgery mission performing inguinal hernias with mesh repair according to the Lichtenstein maneuver. All data were collected prospectively. The contribution to the local health system was measured based on the disability-adjusted life years (DALYs). Further on, the CEA was analyzed and separated for surgeons from Nigeria and Europe, respectively.

Results:

During this mission a total of 107 patients with 123 hernias were treated. An average of 6,61 DALYs per patient were averted. The total costs for the mission team amounted to $8485.26, with a total of $19,210.73 from a societal perspective. Single-procedure costs amounted to $198.87 per patient, with $39.35 per procedure from a patient perspective. The CEA showed $31.04/DALY averted from a societal perspective, $13.71/DALY averted from a provider perspective, and $6.81/DALY averted from a patient perspective. This was well below the threshold of $2790 (gross domestic product per capita). Sensitivity analysis showed robust results.

Conclusion:

With these results we proved CE and remained about 90 times below the threshold of the gross domestic product per capita.

Disability Weights for Pediatric Surgical Procedures: A Systematic Review and Analysis

BACKGROUND

Metrics to measure the burden of surgical conditions, such as disability weights (DWs), are poorly defined, particularly for pediatric conditions. To summarize the literature on DWs of children's surgical conditions, we performed a systematic review of disability weights of pediatric surgical conditions in low- and middle-income countries (LMICs).

METHOD

For this systematic review, we searched MEDLINE for pediatric surgery cost-effectiveness studies in LMICs, published between January 1, 1996, and April 1, 2017. We also included DWs found in the Global Burden of Disease studies, bibliographies of studies identified in PubMed, or through expert opinion of authors (ES and HR).

RESULTS

Out of 1427 publications, 199 were selected for full-text analysis, and 30 met all eligibility criteria. We identified 194 discrete DWs published for 66 different pediatric surgical conditions. The DWs were primarily derived from the Global Burden of Disease studies (72%). Of the 194 conditions with reported DWs, only 12 reflected pre-surgical severity, and 12 included postsurgical severity. The methodological quality of included studies and DWs for specific conditions varied greatly.

INTERPRETATION

It is essential to accurately measure the burden, cost-effectiveness, and impact of pediatric surgical disease in order to make informed policy decisions. Our results indicate that the existing DWs are inadequate to accurately quantify the burden of pediatric surgical conditions. A wider set of DWs for pediatric surgical conditions needs to be developed, taking into account factors specific to the range and severity of surgical conditions.

International guidelines for groin hernia management

INTRODUCTION

Worldwide, more than 20 million patients undergo groin hernia repair annually. The many different approaches, treatment indications and a significant array of techniques for groin hernia repair warrant guidelines to standardize care, minimize complications, and improve results. The main goal of these guidelines is to improve patient outcomes, specifically to decrease recurrence rates and reduce chronic pain, the most frequent problems following groin hernia repair. They have been endorsed by all five continental hernia societies, the International Endo Hernia Society and the European Association for Endoscopic Surgery.

METHODS

An expert group of international surgeons (the HerniaSurge Group) and one anesthesiologist pain expert was formed. The group consisted of members from all continents with specific experience in hernia-related research. Care was taken to include surgeons who perform different types of repair and had preferably performed research on groin hernia surgery. During the Group's first meeting, evidence-based medicine (EBM) training occurred and 166 key questions (KQ) were formulated. EBM rules were followed in complete literature searches (including a complete search by The Dutch Cochrane database) to January 1, 2015 and to July 1, 2015 for level 1 publications. The articles were scored by teams of two or three according to Oxford, SIGN and Grade methodologies. During five 2-day meetings, results were discussed with the working group members leading to 136 statements and 88 recommendations. Recommendations were graded as "strong" (recommendations) or "weak" (suggestions) and by consensus in some cases upgraded. In the Results and summary section below, the term "should" refers to a recommendation. The AGREE II instrument was used to validate the guidelines. An external review was performed by three international experts. They recommended the guidelines with high scores. The risk factors for inguinal hernia (IH) include: family history, previous contra-lateral hernia, male gender, age, abnormal collagen metabolism, prostatectomy, and low body mass index. Peri-operative risk factors for recurrence include poor surgical techniques, low surgical volumes, surgical inexperience and local anesthesia. These should be considered when treating IH patients. IH diagnosis can be confirmed by physical examination alone in the vast majority of patients with appropriate signs and symptoms. Rarely, ultrasound is necessary. Less commonly still, a dynamic MRI or CT scan or herniography may be needed. The EHS classification system is suggested to stratify IH patients for tailored treatment, research and audit. Symptomatic groin hernias should be treated surgically. Asymptomatic or minimally symptomatic male IH patients may be managed with "watchful waiting" since their risk of hernia-related emergencies is low. The majority of these individuals will eventually require surgery; therefore, surgical risks and the watchful waiting strategy should be discussed with patients. Surgical treatment should be tailored to the surgeon's expertise, patient- and hernia-related characteristics and local/national resources. Furthermore, patient health-related, life style and social factors should all influence the shared decision-making process leading up to hernia management. Mesh repair is recommended as first choice, either by an open procedure or a laparo-endoscopic repair technique. One standard repair technique for all groin hernias does not exist. It is recommended that surgeons/surgical services provide both anterior and posterior approach options. Lichtenstein and laparo-endoscopic repair are best evaluated. Many other techniques need further evaluation. Provided that resources and expertise are available, laparo-endoscopic techniques have faster recovery times, lower chronic pain risk and are cost effective. There is discussion concerning laparo-endoscopic management of potential bilateral hernias (occult hernia issue). After patient consent, during TAPP, the contra-lateral side should be inspected. This is not suggested during unilateral TEP repair. After appropriate discussions with patients concerning results tissue repair (first choice is the Shouldice technique) can be offered. Day surgery is recommended for the majority of groin hernia repair provided aftercare is organized. Surgeons should be aware of the intrinsic characteristics of the meshes they use. Use of so-called low-weight mesh may have slight short-term benefits like reduced postoperative pain and shorter convalescence, but are not associated with better longer-term outcomes like recurrence and chronic pain. Mesh selection on weight alone is not recommended. The incidence of erosion seems higher with plug versus flat mesh. It is suggested not to use plug repair techniques. The use of other implants to replace the standard flat mesh in the Lichtenstein technique is currently not recommended. In almost all cases, mesh fixation in TEP is unnecessary. In both TEP and TAPP it is recommended to fix mesh in M3 hernias (large medial) to reduce recurrence risk. Antibiotic prophylaxis in average-risk patients in low-risk environments is not recommended in open surgery. In laparo-endoscopic repair it is never recommended. Local anesthesia in open repair has many advantages, and its use is recommended provided the surgeon is experienced in this technique. General anesthesia is suggested over regional in patients aged 65 and older as it might be associated with fewer complications like myocardial infarction, pneumonia and thromboembolism. Perioperative field blocks and/or subfascial/subcutaneous infiltrations are recommended in all cases of open repair. Patients are recommended to resume normal activities without restrictions as soon as they feel comfortable. Provided expertise is available, it is suggested that women with groin hernias undergo laparo-endoscopic repair in order to decrease the risk of chronic pain and avoid missing a femoral hernia. Watchful waiting is suggested in pregnant women as groin swelling most often consists of self-limited round ligament varicosities. Timely mesh repair by a laparo-endoscopic approach is suggested for femoral hernias provided expertise is available. All complications of groin hernia management are discussed in an extensive chapter on the topic. Overall, the incidence of clinically significant chronic pain is in the 10-12% range, decreasing over time. Debilitating chronic pain affecting normal daily activities or work ranges from 0.5 to 6%. Chronic postoperative inguinal pain (CPIP) is defined as bothersome moderate pain impacting daily activities lasting at least 3 months postoperatively and decreasing over time. CPIP risk factors include: young age, female gender, high preoperative pain, early high postoperative pain, recurrent hernia and open repair. For CPIP the focus should be on nerve recognition in open surgery and, in selected cases, prophylactic pragmatic nerve resection (planned resection is not suggested). It is suggested that CPIP management be performed by multi-disciplinary teams. It is also suggested that CPIP be managed by a combination of pharmacological and interventional measures and, if this is unsuccessful, followed by, in selected cases (triple) neurectomy and (in selected cases) mesh removal. For recurrent hernia after anterior repair, posterior repair is recommended. If recurrence occurs after a posterior repair, an anterior repair is recommended. After a failed anterior and posterior approach, management by a specialist hernia surgeon is recommended. Risk factors for hernia incarceration/strangulation include: female gender, femoral hernia and a history of hospitalization related to groin hernia. It is suggested that treatment of emergencies be tailored according to patient- and hernia-related factors, local expertise and resources. Learning curves vary between different techniques. Probably about 100 supervised laparo-endoscopic repairs are needed to achieve the same results as open mesh surgery like Lichtenstein. It is suggested that case load per surgeon is more important than center volume. It is recommended that minimum requirements be developed to certify individuals as expert hernia surgeon. The same is true for the designation "Hernia Center". From a cost-effectiveness perspective, day-case laparoscopic IH repair with minimal use of disposables is recommended. The development and implementation of national groin hernia registries in every country (or region, in the case of small country populations) is suggested. They should include patient follow-up data and account for local healthcare structures. A dissemination and implementation plan of the guidelines will be developed by global (HerniaSurge), regional (international societies) and local (national chapters) initiatives through internet websites, social media and smartphone apps. An overarching plan to improve access to safe IH surgery in low-resource settings (LRSs) is needed. It is suggested that this plan contains simple guidelines and a sustainability strategy, independent of international aid. It is suggested that in LRSs the focus be on performing high-volume Lichtenstein repair under local anesthesia using low-cost mesh. Three chapters discuss future research, guidelines for general practitioners and guidelines for patients.

CONCLUSIONS

The HerniaSurge Group has developed these extensive and inclusive guidelines for the management of adult groin hernia patients. It is hoped that they will lead to better outcomes for groin hernia patients wherever they live. More knowledge, better training, national audit and specialization in groin hernia management will standardize care for these patients, lead to more effective and efficient healthcare and provide direction for future research.

Cost-effectiveness of short-term neurosurgical missions relative to other surgical specialties

Background:

Short-term surgical relief efforts have helped close some gaps in the provision of surgical care in remote settings. We reviewed the published literature on short-term surgical missions to compare their cost-effectiveness across subspecialties.

Methods:

PubMed was searched using the algorithm [“cost-effectiveness” AND “surgery” AND (“mission” OR “volunteer”)]. Articles detailing the cost-effectiveness of short-term surgical missions in low and middle-income countries (LMIC) were included. Only direct mission costs were considered, and all costs were converted into 2014 USD.

Results:

Eight articles, representing 27 missions in 9 LMIC countries during 2006–2014, met our inclusion criteria. Latin America was the most frequently visited region. Per capita costs ranged from $259 for cleft lip/cleft palate (CL/CP) missions to $2900 for a neurosurgery mission. Mission effectiveness ranged from 3 disability adjusted life years (DALYs) averted per patient for orthopedic surgery missions to 8.12 DALYs averted per patient for a neurosurgery mission. CL/CP and general surgery missions were the most cost-effective, averaging $80/DALY and $87/DALY, respectively. The neurosurgical, orthopedic, and hand surgery missions averaged the highest costs/DALY averted, with the cost-effectiveness being $357/DALY, $435/DALY, and $445/DALY, respectively. All analyzed missions were very cost effective.

Conclusion:

To date, this is the first study to assess the cost-effectiveness of short-term surgical missions across surgical specialties. Neurosurgical missions avert the largest number of healthy life years compared to other specialties, and thus, could yield a greater long-term benefit to resource-poor communities. We recommend that further studies be carried out to assess the impact of surgical missions in low-resource settings.

Cost-effectiveness of groin hernia repair from a randomized clinical trial comparing commercial versus low-cost mesh in a low-income country

BACKGROUND

Over 200 million people worldwide live with groin hernia and 20 million are operated on each year. In resource-scarce settings, the superior surgical technique using a synthetic mesh is not affordable. A low-cost alternative is needed. The objective of this study was to calculate and compare costs and cost-effectiveness of inguinal hernia mesh repair using a low-cost versus a commercial mesh in a rural setting in Uganda.

METHODS

This is a cost-effectiveness analysis of a double-blinded RCT comparing outcomes from groin hernia mesh repair using a low-cost mesh and a commercially available mesh. Cost-effectiveness was expressed in US dollars (with euros in parentheses, exchange rate 30 December 2016) per disability-adjusted life-year (DALY) averted and quality-adjusted life-year (QALY) gained.

RESULTS

The cost difference resulting from the choice of mesh was $124·7 (€118·1). In the low-cost mesh group, the cost per DALY averted and QALY gained were $16·8 (€15·9) and $7·6 (€7·2) respectively. The corresponding costs were $58·2 (€55·1) and $33·3 (€31·5) in the commercial mesh group. A sensitivity analysis was undertaken including cost variations and different health outcome scenarios. The maximum costs per DALY averted and QALY gained were $148·4 (€140·5) and $84·7 (€80·2) respectively.

CONCLUSION

Repair using both meshes was highly cost-effective in the study setting. A potential cost reduction of over $120 (nearly €120) per operation with use of the low-cost mesh is important if the mesh technique is to be made available to the many millions of patients in countries with limited resources.

Variability in mortality following caesarean delivery, appendectomy, and groin hernia repair in low-income and middle-income countries: a systematic review and analysis of published data

BACKGROUND

Surgical interventions occur at lower rates in resource-poor settings, and complication and death rates following surgery are probably substantial but have not been well quantified. A deeper understanding of outcomes is a crucial step to ensure that high quality accompanies increased global access to surgical care. We aimed to assess surgical mortality following three common surgical procedures--caesarean delivery, appendectomy, and groin (inguinal and femoral) hernia repair--to quantify the potential risks of expanding access without simultaneously addressing issues of quality and safety.

METHODS

We collected demographic, health, and economic data for 113 countries classified as low income or lower-middle income by the World Bank in 2005. We did a systematic review of Ovid, MEDLINE, PubMed, and Scopus from Jan 1, 2000, to Jan 15, 2015, to identify studies in these countries reporting all-cause mortality following the three commonly undertaken operations. Reports from governmental and other agencies were also identified and included. We modelled surgical mortality rates for countries without reported data using a two-step multiple imputation method. We first used a fully conditional specification (FCS) multiple imputation method to establish complete datasets for all missing variables that we considered potentially predictive of surgical mortality. We then used regression-based predictive mean matching imputation methods, specified within the multiple imputation FCS method, for selected predictors for each operation using the completed dataset to predict mortality rates along with confidence intervals for countries without reported mortality data. To account for variability in data availability, we aggregated results by subregion and estimated surgical mortality rates.

FINDINGS

From an initial 1302 articles and reports identified, 247 full-text articles met our inclusion criteria, and 124 provided data for surgical mortality for at least one of the three selected operations. We identified 42 countries with mortality data for at least one of the three procedures. Median reported mortality was 7·9 per 1000 operations for caesarean delivery (IQR 2·8-19·9), 2·2 per 1000 operations for appendectomy (0·0-17·2), and 4·9 per 1000 operations for groin hernia (0·0-11·7). Perioperative mortality estimates by subregion ranged from 2·8 (South Asia) to 50·2 (East Asia) per 1000 caesarean deliveries, 2·4 (South Asia) to 54·0 (Central sub-Saharan Africa) per 1000 appendectomies, and 0·3 (Andean Latin America) to 25·5 (Southern sub-Saharan Africa) per 1000 hernia repairs.

INTERPRETATION

All-cause postoperative mortality rates are exceedingly variable within resource-constrained environments. Efforts to expand surgical access and provision of services must include a strong commitment to improve the safety and quality of care.

FUNDING

None.

The How Project: understanding contextual challenges to global surgical care provision in low-resource settings

INTRODUCTION

5 billion people around the world do not have access to safe, affordable, timely surgical care. This series of qualitative interviews was launched by The Lancet Commission on Global Surgery (LCoGS) with the aim of understanding the contextual challenges-the specific circumstances-faced by surgical care providers in low-resource settings who care for impoverished patients, and how those providers overcome these challenges.

METHODS

From January 2014 to February 2015, 20 LCoGS collaborators conducted semistructured interviews with 148 surgical providers in low-resource settings in 21 countries. Stratified purposive sampling was used to include both rural and urban providers, and reputational case selection identified individuals. Interviewers were trained with an implementation manual. Following immersion into de-identified texts from completed interviews, topical coding and further analysis of coded texts was completed by an independent analyst with periodic validation from a second analyst.

RESULTS

Providers described substantial financial, geographic and cultural barriers to patient access. Rural surgical teams reported a lack of a trained workforce and insufficient infrastructure, equipment, supplies and banked blood. Urban providers face overcrowding, exacerbated by minimal clinical and administrative support, and limited interhospital care coordination. Many providers across contexts identified national health policies that do not reflect the realities of resource-poor settings. Some findings were region-specific, such as weak patient-provider relationships and unreliable supply chains. In all settings, surgical teams have created workarounds to deliver care despite the challenges.

DISCUSSION

While some differences exist between countries, the barriers to safe surgery and anaesthesia are overall consistent and resource-dependent. Efforts to advance and expand global surgery must address these commonalities, while local policymakers can tailor responses to key contextual differences.

Economic Valuation of the Global Burden of Cleft Disease Averted by a Large Cleft Charity

BACKGROUND

This study attempts to quantify the burden of disease averted through the global surgical work of a large cleft charity, and estimate the economic impact of this effort over a 10-year period.

METHODS

Anonymized data of all primary cleft lip and cleft palate procedures in the Smile Train database were analyzed and disability-adjusted life years (DALYs) calculated using country-specific life expectancy tables, established disability weights, and estimated success of surgery and residual disability probabilities; multiple age weighting and discounting permutations were included. Averted DALYs were calculated and gross national income (GNI) per capita was then multiplied by averted DALYs to estimate economic gains.

RESULTS

548,147 primary cleft procedures were performed in 83 countries between 2001 and 2011. 547,769 records contained complete data available for the study; 58 % were cleft lip and 42 % cleft palate. Averted DALYs ranged between 1.46 and 4.95 M. The mean economic impact ranged between USD 5510 and 50,634 per person. This corresponded to a global economic impact of between USD 3.0B and 27.7B USD, depending on the DALY and GNI values used. The estimated cost of providing these procedures based on an average reimbursement rate was USD 197M (0.7-6.6 % of the estimated impact).

CONCLUSIONS

The immense economic gain realized through procedures focused on a small proportion of the surgical burden of disease highlights the importance and cost-effectiveness of surgical treatment globally. This methodology can be applied to evaluate interventions for other conditions, and for evidence-based health care resource allocation.

Economic Analysis of Children's Surgical Care in Low- and Middle-Income Countries: A Systematic Review and Analysis

Background

Understanding the economic value of health interventions is essential for policy makers to make informed resource allocation decisions. The objective of this systematic review was to summarize available information on the economic impact of children’s surgical care in low- and middle-income countries (LMICs).

Methods

We searched MEDLINE (Pubmed), Embase, and Web of Science for relevant articles published between Jan. 1996 and Jan. 2015. We summarized reported cost information for individual interventions by country, including all costs, disability weights, health outcome measurements (most commonly disability-adjusted life years [DALYs] averted) and cost-effectiveness ratios (CERs). We calculated median CER as well as societal economic benefits (using a human capital approach) by procedure group across all studies. The methodological quality of each article was assessed using the Drummond checklist and the overall quality of evidence was summarized using a scale adapted from the Agency for Healthcare Research and Quality.

Findings

We identified 86 articles that met inclusion criteria, spanning 36 groups of surgical interventions. The procedure group with the lowest median CER was inguinal hernia repair ($15/DALY). The procedure group with the highest median societal economic benefit was neurosurgical procedures ($58,977). We found a wide range of study quality, with only 35% of studies having a Drummond score ≥ 7.

Interpretation

Our findings show that many areas of children’s surgical care are extremely cost-effective in LMICs, provide substantial societal benefits, and are an appropriate target for enhanced investment. Several areas, including inguinal hernia repair, trichiasis surgery, cleft lip and palate repair, circumcision, congenital heart surgery and orthopedic procedures, should be considered “Essential Pediatric Surgical Procedures” as they offer considerable economic value. However, there are major gaps in existing research quality and methodology which limit our current understanding of the economic value of surgical care.

A Systematic Review of Health Economic Evaluation Studies Using the Patient's Perspective

BACKGROUND

Patient-centered care has become increasingly important and relevant for informed health care decision making.

OBJECTIVE

Our study aimed to perform a systematic review of health economic evaluation studies from the patient's perspective.

METHODS

PubMed, EMBASE, and Cochrane Central databases were searched through May 2014 for cost-effectiveness, cost-utility, and cost-benefit studies using the patient's perspective in their analysis. The reporting quality of the studies was evaluated on the basis of Consolidated Health Economic Evaluation Reporting Standards.

RESULTS

We identified 30 health economic evaluations using the patient's perspective, of which 7 were conducted in the United States, 9 in Europe, and 14 in Asian or other countries. Seventeen of 23 health conditions evaluated were chronic in nature. Among 12 studies that justified the use of the patient's perspective, patient's financial burden associated with medical treatment was the most commonly cited rationale. A total of 29, 17, and 15 studies examined direct medical, direct nonmedical, and indirect costs, respectively. Seventeen studies also included societal, governmental or payer's, and/or provider's perspective(s) in their analyses. Based on Consolidated Health Economic Evaluation Reporting Standards, more than 20% of the reporting items in these studies were either partially satisfied or not satisfied.

CONCLUSIONS

There is a paucity of health economic evaluations conducted from the patient's perspective in the literature. For those studies using the patient's perspective, the true patient costs were not fully explored and study reporting quality was not optimal. With the increasing focus on patient-centered outcomes in health policy research, more frequent use of the patient's perspective in economic studies should be advocated.

A Randomized Trial of Low-Cost Mesh in Groin Hernia Repair

BACKGROUND

The most effective method for repair of a groin hernia involves the use of a synthetic mesh, but this type of mesh is unaffordable for many patients in low- and middle-income countries. Sterilized mosquito meshes have been used as a lower-cost alternative but have not been rigorously studied.

METHODS

We performed a double-blind, randomized, controlled trial comparing low-cost mesh with commercial mesh (both lightweight) for the repair of a groin hernia in adult men in eastern Uganda who had primary, unilateral, reducible groin hernias. Surgery was performed by four qualified surgeons. The primary outcomes were hernia recurrence at 1 year and postoperative complications.

RESULTS

A total of 302 patients were included in the study. The follow-up rate was 97.3% after 2 weeks and 95.6% after 1 year. Hernia recurred in 1 patient (0.7%) assigned to the low-cost mesh and in no patients assigned to the commercial mesh (absolute risk difference, 0.7 percentage points; 95% confidence interval [CI], -1.2 to 2.6; P=1.0). Postoperative complications occurred in 44 patients (30.8%) assigned to the low-cost mesh and in 44 patients (29.7%) assigned to the commercial mesh (absolute risk difference, 1.0 percentage point; 95% CI, -9.5 to 11.6; P=1.0).

CONCLUSIONS

Rates of hernia recurrence and postoperative complications did not differ significantly between men undergoing hernia repair with low-cost mesh and those undergoing hernia repair with commercial mesh.

Patient safety challenges in low-income and middle-income countries

PURPOSE OF REVIEW

The global burden of surgical disease is significant and growing. As a result, the vital role of essential surgical care and safe anesthesia in low-income and middle-income countries is gaining increasing attention. Importantly, vast disparities in access to essential surgery and safe anesthesia exist. In this review, we summarize the current knowledge surrounding the global crisis of inadequate anesthesia capacity and barriers to patient safety in low-income and middle-income countries.

RECENT FINDINGS

The major patient safety challenges in low-income and middle-income countries include a lack of well trained anesthesia providers, inadequate infrastructure, equipment, monitors, medicines, oxygen, and blood products, and an absence of meaningful data to guide policies and programs.

SUMMARY

Explicit mention of essential surgery and safe anesthesia in the Post-2015 Development Agenda is a critical step forward in advancing the cause of global perioperative care. Tracking surgical and anesthesia outcomes with a metric, such as the perioperative mortality rate, must be required at the hospital, country, and global level to guide improvement of surgical and anesthetic interventions aimed at the burden of surgical disease.

Innovation in income-poor environments

Background

At the core of surgical development in any economic environment lies innovation. Innovation in high-income countries (HICs) often derives from research, whereas innovation in low- and middle-income countries (LMICs) may be spontaneous owing to a desperate drive to meet a local need. The local needs are substantial because of the unequal access to healthcare in LMICs.

Methods

The experience of the author in working in LMICs through Operation Hernia, a medical charity, provides a backdrop for this review. Other published innovative devices and models are discussed.

Results

Innovation in income-poor countries has provided cost-effective but efficient solutions to local health needs. Some innovations have been enhanced and adopted worldwide.

Conclusion

HICs can learn more from innovative strategies adopted in LMICs.

Cost-effectiveness of surgery in low- and middle-income countries: a systematic review

BACKGROUND

There is increasing interest in provision of essential surgical care as part of public health policy in low- and middle-income countries (LMIC). Relatively simple interventions have been shown to prevent death and disability. We reviewed the published literature to examine the cost-effectiveness of simple surgical interventions which could be made available at any district hospital, and compared these to standard public health interventions.

METHODS

PubMed and EMBASE were searched using single and combinations of the search terms "disability adjusted life year" (DALY), "quality adjusted life year," "cost-effectiveness," and "surgery." Articles were included if they detailed the cost-effectiveness of a surgical intervention of relevance to a LMIC, which could be made available at any district hospital. Suitable articles with both cost and effectiveness data were identified and, where possible, data were extrapolated to enable comparison across studies.

RESULTS

Twenty-seven articles met our inclusion criteria, representing 64 LMIC over 16 years of study. Interventions that were found to be cost-effective included cataract surgery (cost/DALY averted range US$5.06-$106.00), elective inguinal hernia repair (cost/DALY averted range US$12.88-$78.18), male circumcision (cost/DALY averted range US$7.38-$319.29), emergency cesarean section (cost/DALY averted range US$18-$3,462.00), and cleft lip and palate repair (cost/DALY averted range US$15.44-$96.04). A small district hospital with basic surgical services was also found to be highly cost-effective (cost/DALY averted 1 US$0.93), as were larger hospitals offering emergency and trauma surgery (cost/DALY averted US$32.78-$223.00). This compares favorably with other standard public health interventions, such as oral rehydration therapy (US$1,062.00), vitamin A supplementation (US$6.00-$12.00), breast feeding promotion (US$930.00), and highly active anti-retroviral therapy for HIV (US$922.00).

CONCLUSIONS

Simple surgical interventions that are life-saving and disability-preventing should be considered as part of public health policy in LMIC. We recommend an investment in surgical care and its integration with other public health measures at the district hospital level, rather than investment in single disease strategies.

Global disease burden of conditions requiring emergency surgery

BACKGROUND

Surgical disease is inadequately addressed globally, and emergency conditions requiring surgery contribute substantially to the global disease burden.

METHODS

This was a review of studies that contributed to define the population-based health burden of emergency surgical conditions (excluding trauma and obstetrics) and the status of available capacity to address this burden. Further data were retrieved from the Global Burden of Disease Study 2010 and the University of Washington's Institute for Health Metrics and Evaluation online data.

RESULTS

In the index year of 2010, there were 896,000 deaths, 20 million years of life lost and 25 million disability-adjusted life-years from 11 emergency general surgical conditions reported individually in the Global Burden of Disease Study. The most common cause of death was complicated peptic ulcer disease, followed by aortic aneurysm, bowel obstruction, biliary disease, mesenteric ischaemia, peripheral vascular disease, abscess and soft tissue infections, and appendicitis. The mortality rate was higher in high-income countries (HICs) than in low- and middle-income countries (LMICs) (24.3 versus 10.6 deaths per 100,000 inhabitants respectively), primarily owing to a higher rate of vascular disease in HICs. However, because of the much larger population, 70 per cent of deaths occurred in LMICs. Deaths from vascular disease rose from 15 to 25 per cent of surgical emergency-related deaths in LMICs (from 1990 to 2010). Surgical capacity to address this burden is suboptimal in LMICs, with fewer than one operating theatre per 100,000 inhabitants in many LMICs, whereas some HICs have more than 14 per 100,000 inhabitants.

CONCLUSION

The global burden of surgical emergencies is described insufficiently. The bare estimates indicate a tremendous health burden. LMICs carry the majority of emergency conditions; in these countries the pattern of surgical disease is changing and capacity to deal with the problem is inadequate. The data presented in this study will be useful for both the surgical and public health communities to plan a more adequate response.

A material cost-minimization analysis for hernia repairs and minor procedures during a surgical mission in the Dominican Republic

INTRODUCTION

Expenditures on material supplies and medications constitute the greatest per capita costs for surgical missions. We hypothesized that supply acquisition at non-profit organization (NPO) costs would lead to significant cost-savings compared with supply acquisition at US academic institution costs from the provider perspective for hernia repairs and minor procedures during a surgical mission in the Dominican Republic.

METHODS

Items acquired for a surgical mission were uniquely QR-coded for accurate consumption accounting. Both NPO and US academic institution unit costs were associated with each item in an electronic inventory system. Medication doses were recorded and QR codes for consumed items were scanned into a record for each sampled procedure. Mean material costs and cost-savings ± SDs were calculated in US dollars for each procedure type. Cost-minimization analyses between the NPO and the US academic institution platforms for each procedure type ensued using a two-tailed Wilcoxon matched-pairs test with α = 0.05. Item utilization analyses generated lists of most frequently used materials by procedure type.

RESULTS

The mean cost-savings of supply acquisition at NPO costs for each procedure type were as follows: $482.86 ± $683.79 for unilateral inguinal hernia repair (n = 13); $332.46 ± $184.09 for bilateral inguinal hernia repair (n = 3); $127.26 ± $13.18 for hydrocelectomy (n = 9); $232.92 ± $56.49 for femoral hernia repair (n = 3); $120.90 ± $30.51 for umbilical hernia repair (n = 8); $36.59 ± $17.76 for minor procedures (n = 26); and $120.66 ± $14.61 for pediatric inguinal hernia repair (n = 7).

CONCLUSION

Supply acquisition at NPO costs leads to significant cost-savings compared with supply acquisition at US academic institution costs from the provider perspective for inguinal hernia repair, hydrocelectomy, umbilical hernia repair, minor procedures, and pediatric inguinal hernia repair during a surgical mission in the Dominican Republic. Item utilization analysis can generate minimum-necessary material lists for each procedure type to reproduce cost-savings for subsequent missions.
