The Global Otolaryngology-Head and Neck Surgery Workforce.

Importance: A core component of delivering care of head and neck diseases is an adequate workforce. The World Health Organization report, Multi-Country Assessment of National Capacity to Provide Hearing Care, captured primary workforce estimates from 68 member states in 2012, noting that response rates were a limitation and that updated more comprehensive data are needed. Objective: To establish comprehensive workforce metrics for global otolaryngology-head and neck surgery (OHNS) with updated data from more countries/territories. Design, Setting, and Participants: A cross-sectional electronic survey characterizing the OHNS workforce was disseminated from February 10 to June 22, 2022, to professional society leaders, medical licensing boards, public health officials, and practicing OHNS clinicians. Main Outcome: The OHNS workforce per capita, stratified by income and region. Results: Responses were collected from 121 of 195 countries/territories (62%). Survey responses specifically reported on OHNS workforce from 114 countries/territories representing 84% of the world's population. The global OHNS clinician density was 2.19 (range, 0-61.7) OHNS clinicians per 100 000 population. The OHNS clinician density varied by World Bank income group with higher-income countries associated with a higher density of clinicians. Regionally, Europe had the highest clinician density (5.70 clinicians per 100 000 population) whereas Africa (0.18 clinicians per 100 000 population) and Southeast Asia (1.12 clinicians per 100 000 population) had the lowest. The OHNS clinicians deliver most of the surgical management of ear diseases and hearing care, rhinologic and sinus diseases, laryngeal disorders, and upper aerodigestive mucosal cancer globally. Conclusion and Relevance: This cross-sectional survey study provides a comprehensive assessment of the global OHNS workforce. These results can guide focused investment in training and policy development to address disparities in the availability of OHNS clinicians.

Essential equipment and services for otolaryngology care: a proposal by the Global Otolaryngology-Head and Neck Surgery Initiative.

PURPOSE OF REVIEW: To highlight the need for comprehensive resource lists to provide baseline care of otolaryngologic conditions; to present a proposed list of essential equipment and services that may be applied toward surgical systems research, policymaking, and charitable efforts in global otolaryngology-head and neck surgery. RECENT FINDINGS: To provide effective and high-quality surgical care across care settings, there must be a global standard for equipment and ancillary services necessary to provide baseline care. Though there have been efforts to devise resource standards via equipment lists and appraisal tools, these have been limited in scope to general surgery, emergency care, and a few other subspecialty surgical contexts. Recent efforts have brought attention to the significant burden imposed by otolaryngologic conditions such as hearing loss, otitis media, head and neck cancer, head and neck trauma, and upper airway foreign bodies. Yet, there has not been a comprehensive list of resources necessary to provide baseline care for common otolaryngologic conditions. SUMMARY: Through an internal survey of its members, the Global Otolaryngology-Head and Neck Surgery Initiative has compiled a list of essential equipment and services to provide baseline care of otolaryngologic conditions. Our efforts aimed to address common otolaryngologic conditions that have been previously identified as high-priority with respect to prevalence and burden of disease. This expert-driven list of essential resources functions as an initial framework to be adapted for internal quality assessment, implementation research, health policy development, and economic priority-setting.

Impact of out-of-pocket expenses for surgical care on households in rural Haiti: a mixed-methods study.

OBJECTIVES: This study aimed to report household catastrophic spending on surgery and the experiences of patients and families seeking surgical care in rural Haiti. DESIGN: The study used an explanatory, sequential mixed-methods approach. We collected both quantitative and qualitative data from the participants through interviews. SETTING: A rural tertiary hospital (St. Boniface Hospital) in southern Haiti. PARTICIPANTS: There were 200 adult Haitian surgical patients who entered the study. Of these, 41 were excluded due to missing variables or health expenditure outliers. The final sample included 159 participants. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were (1) direct and indirect payments for surgical care; (2) the rate of catastrophic health expenditure (CHE) (as defined by the Sustainable Development Goals (10% of total household expenditure) and WHO (10%, 20%, 30% and 40% of household capacity to pay)) due to surgical care; and (3) common themes across the lived experiences of households of surgical patients seeking care. RESULTS: The median household expenditure on surgery-related expenses was US$385.6, slightly more than half of per capita gross domestic product in Haiti (US$729.3). Up to 86% of households experienced CHE, as defined by the Sustainable Development Goals, due to receiving surgical care. Patients commonly paid for surgical costs through loans and donations (69.8%). The qualitative analysis revealed prominent themes related to barriers to care including the burden of initiating care-seeking, care-seeking journeys and social suffering. CONCLUSIONS: CHE is common for Haitian surgical patients, and the associated care-seeking experiences are often arduous. These findings suggest that low, flat fees in non-profit hospital settings may not be sufficient to mitigate the costs of surgical care or the resulting challenges that patients experience.

Decision aid and preference assessment of topical anesthesia for otolaryngology procedures.

OBJECTIVES: To determine preference patterns for topical anesthesia in patients undergoing endoscopy pre-coronavirus (2019 coronavirus disease [COVID-19]) pandemic and analyze outcomes based on preference, using a decision aid format. METHODS: A decision aid was developed with expert and patient input. New patients presenting to subspecialty clinics over a 2-month pre-COVID-19 period completed a pre-procedure survey about their priorities, then were asked to choose between topical oxymetazoline/lidocaine spray or none. A post-procedure outcome survey followed. RESULTS: Of 151 patients, 90.1% patients elected to have topical anesthesia. Top patient priorities were "I want the scope to be easy for the doctor" and "I want to be as comfortable as possible." Patients who strongly wanted to avoid medication (P = .002) and bad taste (P = .003) were more likely to select no spray, whereas those who wanted to avoid pain received anesthetic (P = .011). According to the post-procedure assessment, 95.4% of patients were satisfied or strongly satisfied their choice, and this did not correlate with anesthetic vs none. CONCLUSIONS: Patient preferences are easily elicited and correlate with treatment choices. Most patients chose to have topical anesthetic and were willing to tolerate side effects; however, both patients with and without topical anesthetic were satisfied with their choices. This decision aid can be used to optimize shared decision making in the otolaryngology clinic. Given the aerosolizing potential of both spray and no spray conditions, this insight may be consequential when devising office protocols for post-COVID-19 practice. LEVEL OF EVIDENCE: II.

Traumatic Brain Injury in Mumbai: A Survey of Providers along the Care Continuum.

INTRODUCTION: Traumatic brain injury (TBI) represents a significant burden of a global disease, especially in low- and middle-income countries (LMICs) such as India. Efforts to curb the impact of TBI require an appreciation of local factors related to this disease and its treatment. METHODS: Semi-structured qualitative interviews were administered to paramedics, anesthesiologists, general surgeons, and neurosurgeons in locations throughout Mumbai from April to May 2018. A thematic analysis with an iterative coding was used to analyze the data. The primary objective was to identify provider-perceived themes related to TBI care in Mumbai. RESULTS: A total of 50 participants were interviewed, including 17 paramedics, 15 anesthesiologists, 9 general surgeons, and 9 neurosurgeons who were involved in caring for TBI patients. The majority of physicians interviewed discussed their experiences in public sector hospitals (82%), while 12% discussed private sector hospitals and 6% discussed both. Four major themes emerged: Workforce, equipment, financing care, and the family and public role. These themes were often discussed in the context of their effects on increasing or decreasing complications and delays. Participants developed adaptations when managing shortcomings in these thematic areas. These adaptations included teamwork during workforce shortages and resource allocation when equipment was limited among others. CONCLUSIONS: Workforce, equipment, financing care, and the family and public role were identified as major themes in the care for TBI in Mumbai. These thematic elements provide a framework to evaluate and improve care along the care spectrum for TBI. Similar frameworks should be adapted to local contexts in urbanizing cities in LMICs.

A country-level comparison of access to quality surgical and non-surgical healthcare from 1990-2016.

BACKGROUND: The Healthcare Access and Quality (HAQ) index, developed by the Institute for Health Metrics and Evaluation, uses estimates of amenable mortality to quantify health system performance over time. While much is known about general health system performance globally, few studies have portrayed the performance of surgical systems. In order to quantify access to quality surgical care, evaluate changes over time, and link these changes to health care investments, surgical and non-surgical Health Access and Quality sub-indices were developed. DESIGN: We categorized 32 amenable mortality causes as either surgical or non-surgical conditions. Using principal components analysis and scaled amenable mortality rates, we constructed a surgical and non-surgical Health Access and Quality sub-index. Using these sub-indices, relative improvement over time was compared. An expenditure model with country fixed effects was built to explore drivers of differences in relative improvement of sub-indices. RESULTS: Compared to low-income countries, high-income countries have been 2.77 times more effective at improving surgical care (p < .05). Government expenditure on healthcare has a larger effect on improving surgical Health Access and Quality (p < 0.05) while development assistance for health has a larger effect on improving non-surgical Health Access and Quality (p < 0.05). CONCLUSIONS AND RELEVANCE: Global health investment must prioritize strengthening health systems as opposed to the historically favored vertical programming. In order to achieve health equity in low-income countries, more focus should be placed on domestic financing of surgical systems. Health Access and Quality sub-indices can be used by countries to identify targets, monitor progress, and evaluate interventions aimed at improving access to quality surgical healthcare.

The Macroeconomic Consequences Of Firearm-Related Fatalities In OECD Countries, 2018-30: A Value-Of-Lost-Output Analysis.

We modeled gross domestic product (GDP) losses attributable to firearm-related fatalities in each of thirty-six Organization for Economic Cooperation and Development (OECD) countries using the value-of-lost-output approach from 2018 to 2030. There are three categories of firearm-related fatalities: physical violence, self-harm, and unintentional injury. We project that the thirty-six OECD countries will lose $239.0 billion in cumulative GDP from 2018 to 2030 from firearm-related fatalities. Most of these losses ($152.5 billion) will occur as a result of fatalities in the US. In 2030 alone, the OECD countries will collectively lose $30.4 billion (0.04 percent) of their estimated annual GDP from firearm-related fatalities. The highest relative losses will occur in Mexico and the US; the lowest will occur in Japan. Firearm-related fatalities are expected to disproportionately affect the US and Mexican economies. Across the OECD, 48.5 percent of economic losses will be attributable to physical violence, 47.0 percent to self-harm, and 4.6 percent to unintentional injury. These findings provide a more complete picture of the toll of firearm-related fatalities, a global public health crisis that, without intervention, will continue to impose significant economic losses across OECD countries.

Toward a complete estimate of physical and psychosocial morbidity from prolonged obstructed labour: a modelling study based on clinician survey.

INTRODUCTION: Prolonged obstructed labour often results from lack of access to timely obstetrical care and affects millions of women. Current burden of disease estimates do not include all the physical and psychosocial sequelae from prolonged obstructed labour. This study aimed to estimate the prevalence of the full spectrum of maternal and newborn comorbidities, and create a more comprehensive burden of disease model. METHODS: This is a cross-sectional survey of clinicians and epidemiological modelling of the burden of disease. A survey to estimate prevalence of prolonged obstructed labour comorbidities was developed for prevalence estimates of 27 comorbidities across seven categories associated with prolonged obstructed labour. The survey was electronically distributed to clinicians caring for women who have suffered from prolonged obstructed labour in Asia and Africa. Prevalence estimates of the sequelae were used to calculate years lost to disability for reproductive age women (15 to 49 years) in 54 low- and middle-income countries that report any prevalence of obstetric fistula. RESULTS: Prevalence estimates were obtained from 132 participants. The median prevalence of reported sequelae within each category were: fistula (6.67% to 23.98%), pelvic floor (6.53% to 8.60%), genitourinary (5.74% to 9.57%), musculoskeletal (6.04% to 11.28%), infectious/inflammatory (5.33% to 9.62%), psychological (7.25% to 24.10%), neonatal (13.63% to 66.41%) and social (38.54% to 59.88%). The expanded methodology calculated a burden of morbidity associated with prolonged obstructed labour among women of reproductive age (15 to 49 years old) in 2017 that is 38% more than the previous estimates. CONCLUSIONS: This analysis provides estimates on the prevalence of physical and psychosocial consequences of prolonged obstructed labour. Our study suggests that the burden of disease resulting from prolonged obstructed labour is currently underestimated. Notably, women who suffer from prolonged obstructed labour have a high prevalence of psychosocial sequelae but these are often not included in burden of disease estimates. In addition to preventative and public health measures, high quality surgical and anaesthesia care are urgently needed to prevent prolonged obstructed labour and its sequelae.

Innovative financing to fund surgical systems and expand surgical care in low-income and middle-income countries.

Strong surgical systems are necessary to prevent premature death and avoidable disability from surgical conditions. The epidemiological transition, which has led to a rising burden of non-communicable diseases and injuries worldwide, will increase the demand for surgical assessment and care as a definitive healthcare intervention. Yet, 5 billion people lack access to timely, affordable and safe surgical and anaesthesia care, with the unmet demand affecting predominantly low-income and middle-income countries (LMICs). Rapid surgical care scale-up is required in LMICs to strengthen health system capabilities, but adequate financing for this expansion is lacking. This article explores the critical role of innovative financing in scaling up surgical care in LMICs. We locate surgical system financing by using a modified fiscal space analysis. Through an analysis of published studies and case studies on recent trends in the financing of global health systems, we provide a conceptual framework that could assist policy-makers in health systems to develop innovative financing strategies to mobilise additional investments for scale-up of surgical care in LMICs. This is the first time such an analysis has been applied to the funding of surgical care. Innovative financing in global surgery is an untapped potential funding source for expanding fiscal space for health systems and financing scale-up of surgical care in LMICs.

Global Burden of Head and Neck Cancer: Economic Consequences, Health, and the Role of Surgery.

OBJECTIVE: We aimed to describe the mortality burden and macroeconomic effects of head and neck cancer as well as delineate the role of surgical workforce in improving head and neck cancer outcomes. STUDY DESIGN: Statistical and economic analysis. SETTING: Research group. SUBJECTS AND METHODS: We conducted a statistical analysis on data from the World Development Indicators and the 2016 Global Burden of Disease study to describe the relationship between surgical workforce and global head and neck cancer mortality-to-incidence ratios. A value of lost output model was used to project the global macroeconomic effects of head and neck cancer. RESULTS: Significant differences in mortality-to-incidence ratios existed between Global Burden of Disease study superregions. An increase of surgical, anesthetic, and obstetric provider density by 10% significantly correlated with a reduction of 0.76% in mortality-to-incidence ratio (P < .0001; adjusted R2 = 0.84). There will be a projected global cumulative loss of $535 billion US dollars (USD) in economic output due to head and neck cancer between 2018 and 2030. Southeast Asia, East Asia, and Oceania will suffer the greatest gross domestic product (GDP) losses at $180 billion USD, and South Asia will lose $133 billion USD. CONCLUSION: The mortality burden of head and neck cancer is increasing and disproportionately affects those in low- and middle-income countries and regions with limited surgical workforces. This imbalance results in large and growing economic losses in countries that already face significant resource constraints. Urgent investment in the surgical workforce is necessary to ensure access to timely surgical services and reverse these negative trends.

Third delay in traumatic brain injury: time to management as a predictor of mortality.

OBJECTIVE: Traumatic brain injury (TBI) is a global epidemic with an increasing incidence in low- and middle-income countries (LMICs). The time from arrival at the hospital to receiving appropriate treatment ("third delay") can vary widely in LMICs, although its association with mortality in TBI remains unknown. METHODS: A retrospective cohort analysis with multivariable logistic regression was conducted using the Toward Improved Trauma Care Outcomes in India database, which contains data from 4 urban trauma centers in India from 2013-2015. RESULTS: There were 6278 TBIs included in the cohort. The patients' median age was 39 years (interquartile range 27-52 years) and 80% of patients were male. The most frequent mechanisms of injury were road traffic accidents (52%) and falls (34%). A majority of cases were transfers from other facilities (79%). In-hospital 30-day mortality was 27%; of patients who died, 21% died within 24 hours of arrival. The median third delay was 10 minutes (interquartile range 0-60 minutes); 34% of cases had moderate third delay (10-60 minutes) and 22% had extended third delay (≥ 61 minutes). Overall 30-day mortality was associated with moderate third delay (OR 1.3, p = 0.001) and extended third delay (OR 1.3, p = 0.001) after adjustment by pertinent covariates. This effect was pronounced for 24-hour mortality: moderate and extended third delays were independently associated with ORs of 3.4 and 3.8, respectively, for 24-hour mortality (both p < 0.001). CONCLUSIONS: Third delay is associated with early mortality in patients with TBI, and represents a target for process improvement in urban trauma centers.

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.

The Economic Consequences Of Mortality Amenable To High-Quality Health Care In Low- And Middle-Income Countries.

We estimated deaths amenable to high-quality health care globally and then modeled the macroeconomic impact in low- and middle-income countries using two macroeconomic perspectives: a value-of-lost-output approach to project gross domestic product (GDP) losses annually for the period 2015-30, and a value-of-lost-welfare approach to estimate the present value of total economic welfare losses in 2015. We estimated that eight million amenable deaths occurred in 2015, 96 percent of them in low- and middle-income countries. The value of lost output resulted in a projected cumulative loss of $11.2 trillion in these countries during 2015-30, with a potential economic output loss of up to 2.6 percent of GDP in low-income countries by 2030, compared to 0.9 percent in upper-middle-income countries. The value-of-lost-welfare approach estimated welfare losses of $6.0 trillion in 2015. Inadequate access to high-quality health care results in significant mortality and imposes a macroeconomic burden that is inequitably distributed, with the largest relative burden falling on low-income countries. Given that these deaths are unnecessary and the projected GDP losses are avoidable, there is a strong ethical and economic case for promoting high-quality health care as an essential component of universal health coverage.

Operative and consultative proportions of neurosurgical disease worldwide: estimation from the surgeon perspective.

OBJECTIVE: The global magnitude of neurosurgical disease is unknown. The authors sought to estimate the surgical and consultative proportion of diseases commonly encountered by neurosurgeons, as well as surgeon case volume and perceived workload. METHODS: An electronic survey was sent to 193 neurosurgeons previously identified via a global surgeon mapping initiative. The survey consisted of three sections aimed at quantifying surgical incidence of neurological disease, consultation incidence, and surgeon demographic data. Surgeons were asked to estimate the proportion of 11 neurological disorders that, in an ideal world, would indicate either neurosurgical operation or neurosurgical consultation. Respondent surgeons indicated their confidence level in each estimate. Demographic and surgical practice characteristics-including case volume and perceived workload-were also captured. RESULTS: Eighty-five neurosurgeons from 57 countries, representing all WHO regions and World Bank income levels, completed the survey. Neurological conditions estimated to warrant neurosurgical consultation with the highest frequency were brain tumors (96%), spinal tumors (95%), hydrocephalus (94%), and neural tube defects (92%), whereas stroke (54%), central nervous system infection (58%), and epilepsy (40%) carried the lowest frequency. Similarly, surgery was deemed necessary for an average of 88% cases of hydrocephalus, 82% of spinal tumors and neural tube defects, and 78% of brain tumors. Degenerative spine disease (42%), stroke (31%), and epilepsy (24%) were found to warrant surgical intervention less frequently. Confidence levels were consistently high among respondents (lower quartile > 70/100 for 90% of questions), and estimates did not vary significantly across WHO regions or among income levels. Surgeons reported performing a mean of 245 cases annually (median 190). On a 100-point scale indicating a surgeon's perceived workload (0-not busy, 100-overworked), respondents selected a mean workload of 75 (median 79). CONCLUSIONS: With a high level of confidence and strong concordance, neurosurgeons estimated that the vast majority of patients with central nervous system tumors, hydrocephalus, or neural tube defects mandate neurosurgical involvement. A significant proportion of other common neurological diseases, such as traumatic brain and spinal injury, vascular anomalies, and degenerative spine disease, demand the attention of a neurosurgeon-whether via operative intervention or expert counsel. These estimates facilitate measurement of the expected annual volume of neurosurgical disease globally.

The economic consequences of neurosurgical disease in low- and middle-income countries.

OBJECTIVE: The objective of this study was to estimate the economic consequences of neurosurgical disease in low- and middle-income countries (LMICs). METHODS: The authors estimated gross domestic product (GDP) losses and the broader welfare losses attributable to 5 neurosurgical disease categories in LMICs using two distinct economic models. The value of lost output (VLO) model projects annual GDP losses due to neurosurgical disease during 2015-2030, and is based on the WHO's "Projecting the Economic Cost of Ill-health" tool. The value of lost economic welfare (VLW) model estimates total welfare losses, which is based on the value of a statistical life and includes nonmarket losses such as the inherent value placed on good health, resulting from neurosurgical disease in 2015 alone. RESULTS: The VLO model estimates the selected neurosurgical diseases will result in $4.4 trillion (2013 US dollars, purchasing power parity) in GDP losses during 2015-2030 in the 90 included LMICs. Economic losses are projected to disproportionately affect low- and lower-middle-income countries, risking up to a 0.6% and 0.54% loss of GDP, respectively, in 2030. The VLW model evaluated 127 LMICs, and estimates that these countries experienced $3 trillion (2013 US dollars, purchasing power parity) in economic welfare losses in 2015. Regardless of the model used, the majority of the losses can be attributed to stroke and traumatic brain injury. CONCLUSIONS: The economic impact of neurosurgical diseases in LMICs is significant. The magnitude of economic losses due to neurosurgical diseases in LMICs provides further motivation beyond already compelling humanitarian reasons for action.

What Do Patients Want from Otolaryngologists? A Discrete Choice Experiment.

Objectives Patient preferences are crucial for the delivery of patient-centered care. Discrete choice experiments (DCEs) are an emerging quantitative methodology used for understanding these preferences. In this study, we employed DCE techniques to understand the preferences of patients presenting for an ear, nose, and throat clinic visit. Study Design DCE. Setting Decision science laboratory. Methods A DCE survey of 5 attributes-wait time, physician experience, physician personality, utilization of visit time, and cost/copayment-was constructed with structured qualitative interviews with patients. The DCE was administered to participants from the general population, who chose among hypothetical scenarios that varied across these attributes. A conditional logit model was used to determine relative attribute importance, with a separate logit model for determining subject effects. Results A total of 161 participants were included. Cost/copayment had the greatest impact on decision making (importance, 32.2%), followed by wait time and physician experience (26.5% and 24.7%, respectively). Physician personality mattered least (4.7%), although all attributes were significantly correlated to decision making. Participants preferred doctors who spent more time performing physical examination than listening or explaining. Participants were willing to pay $52 extra to avoid a 4-week delay in appointment time; $87 extra for a physician with 10 years of experience (vs 0 years); and $9 extra for a caring, friendly, and compassionate doctor (vs formal, efficient, and business-like). Conclusion DCEs allow for powerful economic analyses that may help physicians understand patient preferences. Our model showed that cost is an important factor to patients and that patients are willing to pay extra for timely appointments, experience, and thorough physical examination.

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.

Barriers to Surgical Care and Health Outcomes: A Prospective Study on the Relation Between Wealth, Sex, and Postoperative Complications in the Republic of Congo.

BACKGROUND: Approximately thirty percent of the global burden of disease is comprised of surgical conditions. However, five billion people lack access to surgery, with complex factors acting as barriers. We examined whether patient demographics predict barriers to care, and the relation between these factors and postoperative complications in a prospective cohort. METHODS: Participants included people presenting to a global charity in Republic of Congo with a surgical condition between August 2013 and May 2014. The outcomes were self-reported barrier to care and postoperative complications documented by medical record. Logistic regression was used to adjust for covariates. RESULTS: Of 1237 patients in our study, 1190 (96.2 %) experienced a barrier to care and 126 (10.2 %) experienced a postoperative complication. The most frequently reported barrier was cost (73 %), followed by lack of provider (8.2 %). Greater wealth was associated with decreased odds of cost as a barrier (OR 0.72 [0.57, 0.90]). Greater wealth (OR 1.52 [1.03, 2.25]) and rural home location (OR 3.35 [1.16, 9.62]) were associated with increased odds of no surgeon being available. Cost as a barrier (OR 2.82 [1.02, 7.77]), female sex (OR 3.45 [1.62, 7.33]), and lack of surgeon (OR 5.62 [1.68, 18.77]) were associated with increased odds of postoperative complication. Patient wealth was not associated with odds of postoperative complication. CONCLUSIONS: Barriers to surgery were common in Republic of Congo. Patient wealth and home location may predict barriers to surgery. Addressing gender disparities, access to providers, and patient perception of barriers in addition to removal of barriers may help maximize patient health benefits.
