RESUMO

PURPOSE: Cervical cancer screening is vital in addressing the global burden of cervical cancer. In this study, we describe the coverage and socioeconomic inequalities in the coverage of cervical cancer screening in low- and middle-income countries (LMICs). METHODS: We analyzed data from the women's recode files of the Demographic and Health Surveys conducted in LMICs from 2010 to 2019 with variables on cervical cancer screening. We included women 21 years or older and determined the proportion of women who were screened for cervical cancer by age categories, wealth quintile, type of place of residence, level of education, and marital status. Socioeconomic inequality was measured using the concentration index (CIX) and the slope index of inequality (SII). RESULTS: A total of 269,506 women from 20 surveys in 16 countries were included in the survey. Generally, there was a low coverage of screening, with lower rates among women age 21-24 years, living in rural areas, in the poorest wealth quintile, with no formal education, and who have never been in union with or lived with a man. The CIX and SII values for screening for cervical cancer were positive (pro-rich) for all the countries except Tajikistan in 2012 where they were negative (pro-poor). CONCLUSION: The coverage of cervical cancer screening was low in LMICs with variations by the quintile of wealth (pro-rich) and type of place of residence (pro-urban). To achieve the desired impact of cervical cancer screening services in LMICs, the coverage of cervical cancer screening programs must include women irrespective of the type of place and wealth quintiles.

RESUMO

INTRODUCTION: Obesity is associated with cancer, including gastrointestinal (GI). Data from low (LICs) and lower-middle-income countries (MICs) are limited. METHODS: We utilized data from the Global Burden of Disease Study 2019 to determine the mortality from GI cancer risk of high body mass index (BMI) in these countries. RESULTS: Mortality rates of GI cancers from high BMI increased in LICs and lower MICs, while burdens decreased or remained stable in high and middle-income countries. DISCUSSION: The GI cancer-related burden from high BMI increased in LICs and lower MICs, necessitating a concerted effort to tackle the obesity pandemic.

RESUMO

INTRODUCTION: Approximately 33 million people suffer catastrophic health expenditure (CHE) from surgery and/or anesthesia costs. The aim of this systematic review is to evaluate catastrophic and impoverishing expenditure associated with surgery and anesthesia in low- and middle-income countries (LMICs). METHODS: We performed a systematic review of all studies from 1990 to 2021 that reported CHE in LMICs for treatment of a condition requiring surgical intervention, including cesarean section, trauma care, and other surgery. RESULTS: 77 studies met inclusion criteria. Tertiary facilities (23.4%) were the most frequently studied facility type. Only 11.7% of studies were conducted in exclusively rural health-care settings. Almost 60% of studies were retrospective in nature. The cost of procedures ranged widely, from $26 USD for a cesarean section in Mauritania in 2020 to $74,420 for a pancreaticoduodenectomy in India in 2018. GDP per capita had a narrower range from $315 USD in Malawi in 2019 to $9955 USD in Malaysia in 2015 (Median = $1605.50, interquartile range = $1208.74). 35 studies discussed interventions to reduce cost and catastrophic expenditure. Four of those studies stated that their intervention was not successful, 18 had an unknown or equivocal effect on cost and CHE, and 13 concluded that their intervention did help reduce cost and CHE. CONCLUSIONS: CHE from surgery is a worldwide problem that most acutely affects vulnerable patients in LMICs. Existing efforts are insufficient to meet the true need for affordable surgical care unless assistance for ancillary costs is given to patients and families most at risk from CHE.

RESUMO

PURPOSE: There is limited information on preferences for place of care and death among patients with cancer in low- and middle-income countries (LMICs). The aim was to report the prevalence and determinants of preferences for end-of-life place of care and death among patients with cancer in LMICs and identify concordance between the preferred and actual place of death. METHODS: Systematic review and meta-analysis guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses was conducted. Four electronic databases were searched to identify studies of any design that reported on the preferred and actual place of care and death of patients with cancer in LMICs. A random-effects meta-analysis estimated pooled prevalences, with 95% CI, with subgroup analyses for region and risk of bias. RESULTS: Thirteen studies were included. Of 3,837 patients with cancer, 62% (95% CI, 49 to 75) preferred to die at home; however, the prevalence of actual home death was 37% (95% CI, 13 to 60). Subgroup analyses found that preferences for home as place of death varied from 55% (95% CI, 41 to 69) for Asia to 64% (95% CI, 57 to 71) for South America and 72% (95% CI, 48 to 97) for Africa. The concordance between the preferred and actual place of death was 48% (95% CI, 41 to 55) for South Africa and 92% (95% CI, 88 to 95) for Malaysia. Factors associated with an increased likelihood of preferred home death included performance status and patients with breast cancer. CONCLUSION: There is very little literature from LMICs on the preferences for end-of-life place of care and death among patients with cancer. Rigorous research is needed to help understand how preferences of patients with cancer change during their journey through cancer.

RESUMO

Growth faltering in children (low length for age or low weight for length) during the first 1,000 days of life (from conception to 2 years of age) influences short-term and long-term health and survival1,2. Interventions such as nutritional supplementation during pregnancy and the postnatal period could help prevent growth faltering, but programmatic action has been insufficient to eliminate the high burden of stunting and wasting in low- and middle-income countries. Identification of age windows and population subgroups on which to focus will benefit future preventive efforts. Here we use a population intervention effects analysis of 33 longitudinal cohorts (83,671 children, 662,763 measurements) and 30 separate exposures to show that improving maternal anthropometry and child condition at birth accounted for population increases in length-for-age z-scores of up to 0.40 and weight-for-length z-scores of up to 0.15 by 24 months of age. Boys had consistently higher risk of all forms of growth faltering than girls. Early postnatal growth faltering predisposed children to subsequent and persistent growth faltering. Children with multiple growth deficits exhibited higher mortality rates from birth to 2 years of age than children without growth deficits (hazard ratios 1.9 to 8.7). The importance of prenatal causes and severe consequences for children who experienced early growth faltering support a focus on pre-conception and pregnancy as a key opportunity for new preventive interventions.

RESUMO

The COVID-19 pandemic has forever affected healthcare and posed an incredible challenge to our society to care for our sick. Patients with cancer were found early on to have higher rates of complications with COVID-19. Radiation therapy is an integral part of treatment for many types of gynecologic cancer and adaptation on its utilization during the pandemic varied across the globe. In this review, we detail certain guidelines for the use of radiation in gynecologic cancers during the pandemic as well as real world accounts of how different countries adapted to these guidelines or created their own based on individualized resources, staffing, government restrictions, and societal norms. Critically, this review demonstrates the breadth of fractionation schemes and technologies used when resources were limited but highlights the importance of long term follow-up for many of our patients during this time.

RESUMO

BACKGROUND: Separate studies suggest that the risks from smoking might vary between high-income (HICs), middle-income (MICs), and low-income (LICs) countries, but this has not yet been systematically examined within a single study using standardised approaches. We examined the variations in risks from smoking across different country income groups and some of their potential reasons. METHODS: We analysed data from 134 909 participants from 21 countries followed up for a median of 11·3 years in the Prospective Urban Rural Epidemiology (PURE) cohort study; 9711 participants with myocardial infarction and 11 362 controls from 52 countries in the INTERHEART case-control study; and 11 580 participants with stroke and 11 331 controls from 32 countries in the INTERSTROKE case-control study. In PURE, all-cause mortality, major cardiovascular disease, cancers, respiratory diseases, and their composite were the primary outcomes for this analysis. Biochemical verification of urinary total nicotine equivalent was done in a substudy of 1000 participants in PURE. FINDINGS: In PURE, the adjusted hazard ratio (HR) for the composite outcome in current smokers (vs never smokers) was higher in HICs (HR 1·87, 95% CI 1·65-2·12) than in MICs (1·41, 1·34-1·49) and LICs (1·35, 1·25-1·46; interaction p<0·0001). Similar patterns were observed for each component of the composite outcome in PURE, myocardial infarction in INTERHEART, and stroke in INTERSTROKE. The median levels of tar, nicotine, and carbon monoxide displayed on the cigarette packs from PURE HICs were higher than those on the packs from MICs. In PURE, the proportion of never smokers reporting high second-hand smoke exposure (≥1 times/day) was 6·3% in HICs, 23·2% in MICs, and 14·0% in LICs. The adjusted geometric mean total nicotine equivalent was higher among current smokers in HICs (47·2 µM) than in MICs (31·1 µM) and LICs (25·2 µM; ANCOVA p<0·0001). By contrast, it was higher among never smokers in LICs (18·8 µM) and MICs (11·3 µM) than in HICs (5·0 µM; ANCOVA p=0·0001). INTERPRETATION: The variations in risks from smoking between country income groups are probably related to the higher exposure of tobacco-derived toxicants among smokers in HICs and higher rates of high second-hand smoke exposure among never smokers in MICs and LICs. FUNDING: Full funding sources are listed at the end of the paper (see Acknowledgments).

RESUMO

Breast cancer is now the most commonly diagnosed cancer in the world. The most recent global cancer burden figures estimate that there were 2.26 million incident breast cancer cases in 2020 and the disease is the leading cause of cancer mortality in women worldwide. The incidence is strongly correlated with human development, with a large rise in cases anticipated in regions of the world that are currently undergoing economic transformation. Survival, however, is far less favourable in less developed regions. There are a multitude of factors behind disparities in the global survival rates, including delays in diagnosis and lack of access to effective treatment. The World Health Organization's new Global Breast Cancer Initiative was launched this year to address this urgent global health challenge. It aims to improve survival across the world through three pillars: health promotion, timely diagnosis, and comprehensive treatment and supportive care. In this article, we discuss the key challenges of breast cancer care and control in a global context.

RESUMO

BACKGROUND: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. METHODS: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. FINDINGS: Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference -1·69 [-9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5-8] vs 6 [5-8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52-23·52]; p<0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75-0·86]; p<0·0001). INTERPRETATION: Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status. FUNDING: No funding.

RESUMO

Importance: Tobacco companies have shifted their marketing and production to sub-Saharan African countries, which are in an early stage of the tobacco epidemic. Objective: To estimate changes in the prevalence of current tobacco use and socioeconomic inequalities among male and female participants from 22 sub-Saharan African countries from 2003 to 2019. Design, Setting, and Participants: Secondary data analyses were conducted of sequential Demographic and Health Surveys in 22 sub-Saharan African countries including male and female participants aged 15 to 49 years. The baseline surveys (2003-2011) and the most recent surveys (2011-2019) were pooled. Exposures: Household wealth index and highest educational level were the markers of inequality. Main Outcomes and Measures: Sex-specific absolute and relative changes in age-standardized prevalence of current tobacco use in each country and absolute and relative measures of inequality using pooled data. Results: The survey samples included 428 197 individuals (303 232 female participants [70.8%]; mean [SD] age, 28.6 [9.8] years) in the baseline surveys and 493 032 participants (348 490 female participants [70.7%]; mean [SD] age, 28.5 [9.4] years) in the most recent surveys. Both sexes were educated up to primary (35.7%) or secondary school (40.0%). The prevalence of current tobacco use among male participants ranged from 6.1% (95% CI, 5.2%-6.9%) in Ghana to 38.3% (95% CI, 35.8%-40.8%) in Lesotho in the baseline surveys and from 4.5% (95% CI, 3.7%-5.3%) in Ghana to 46.0% (95% CI, 43.2%-48.9%) in Lesotho during the most recent surveys. The decrease in prevalence ranged from 1.5% (Ghana) to 9.6% (Sierra Leone). The World Health Organization target of a 30% decrease in smoking was achieved among male participants in 8 countries: Rwanda, Nigeria, Ethiopia, Benin, Liberia, Tanzania, Burundi, and Cameroon. For female participants, the number of countries having a prevalence of smoking less than 1% increased from 9 in baseline surveys to 16 in the most recent surveys. The World Health Organization target of a 30% decrease in smoking was achieved among female participants in 15 countries: Cameroon, Namibia, Mozambique, Mali, Liberia, Nigeria, Burundi, Tanzania, Malawi, Kenya, Rwanda, Zimbabwe, Ethiopia, Burkina Faso, and Zambia. For both sexes, the prevalence of tobacco use and the decrease in prevalence of tobacco use were higher among less-educated individuals and individuals with low income. In both groups, the magnitude of inequalities consistently decreased, and its direction remained the same. Absolute inequalities were 3-fold higher among male participants, while relative inequalities were nearly 2-fold higher among female participants. Conclusions and Relevance: Contrary to a projected increase, tobacco use decreased in most sub-Saharan African countries. Persisting socioeconomic inequalities warrant the stricter implementation of tobacco control measures to reach less-educated individuals and individuals with low income.

RESUMO

BACKGROUND: Alcohol consumption and smoking are the leading risk factors for laryngeal cancer (LC). Understanding the variations in disease burden of LC attributable to alcohol use and smoking is critical for LC prevention. METHODS: Disease burden data of LC were retrieved from the Global Burden of Disease Study 2019. We used estimated average percentage change (EAPC) to measure the temporal trends of the age-standardized mortality rate (ASMR) of LC. RESULTS: Globally, while the ASMR of LC decreased by 1.49% (95% CI, 1.41-1.57%) per year between 1990 and 2019, the number of deaths from LC has increased 41.0% to 123.4 thousand in 2019. In 2019, 19.4 and 63.5% of total LC-related deaths were attributable to alcohol use and smoking worldwide, respectively. The ASMR of alcohol- and smoking-related LC decreased by 1.78 and 1.93% per year, whereas the corresponding death number has increased 29.2 and 25.1% during this period, respectively. The decreasing trend was more pronounced in developed countries. In some developing countries, such as Guinea and Mongolia, the LC mortality has shown an unfavorable trend. CONCLUSION: The ubiquitous decrease in LC mortality was largely attributed to the smoking control and highlighted the importance of smoking control policies. However, the disease burden of LC remained in increase and more effective strategies are needed to combat the global increase of alcohol consumption.

RESUMO

BACKGROUND: Low- and middle-income countries (LMICs) experienced increasing rates of colorectal cancer (CRC) incidence in the last decade and lower 5-year survival rates compared to high-income countries (HICs) where the implementation of screening and treatment services have advanced. This review scoped and mapped the literature regarding the content, implementation and uptake of CRC screening interventions as well as opportunities and challenges for the implementation of CRC screening interventions in LMICs. METHODS: We systematically followed a five-step scoping review framework to identify and review relevant literature about CRC screening in LMICs, written in the English language before February 2020. We searched Medline, Embase, Web of Science and Google Scholar for studies targeting the general, asymptomatic, at-risk adult population. The TIDieR tool and an implementation checklist were used to extract data from empirical studies; and we extracted data-informed insights from policy reviews and commentaries. RESULTS: CRC screening interventions (n = 24 studies) were implemented in nine middle-income countries. Population-based screening programmes (n = 11) as well as small-scale screening interventions (n = 13) utilised various recruitment strategies. Interventions that recruited participants face-to-face (alone or in combination with other recruitment strategies) (10/15), opportunistic clinic-based screening interventions (5/6) and educational interventions combined with screening (3/4), seemed to be the strategies that consistently achieved an uptake of > 65% in LMICs. FOBT/FIT and colonoscopy uptake ranged between 14 and 100%. The most commonly reported implementation indicator was 'uptake/reach'. There was an absence of detail regarding implementation indicators and there is a need to improve reporting practice in order to disseminate learning about how to implement programmes. CONCLUSION: Opportunities and challenges for the implementation of CRC screening programmes were related to the reporting of CRC cases and screening, cost-effective screening methods, knowledge about CRC and screening, staff resources and training, infrastructure of the health care system, financial resources, public health campaigns, policy commitment from governments, patient navigation, planning of screening programmes and quality assurance.

RESUMO

Haematological malignancies account for almost 10% of all cancers diagnosed in sub-Saharan Africa, although the exact incidences and treatment outcomes are difficult to discern because population-based cancer registries in the region are still underdeveloped. More research on haematological malignancies in sub-Saharan Africa is required to establish whether these cancers have a natural history similar to those diagnosed in high-income countries, about which more is known. Several factors negatively affect the outcome of haematological malignancies in sub-Saharan Africa, showcasing a need for improved understanding of the clinicobiological profile of these cancers to facilitate prevention, early detection, diagnosis, and appropriate treatment through increased capacity building, infrastructure, community awareness, coordinated resource mobilisation, and collaboration across the world. The east African governments have pooled resources for common investments to tackle non-communicable diseases, developing the East Africa's Centres of Excellence for Skills and Tertiary Education project funded by the African Development Bank, an initiative that could be replicated for the care of haematological malignancies in other countries in sub-Saharan Africa.

RESUMO

Cancer mortality rates in low-income and middle-income countries (LMICs) are unacceptably high, requiring both collaborative global effort and in-country solutions. Experience has shown that working together in policy, clinical practice, education, training, and research leads to bidirectional benefit for LMICs and high-income countries. For over 60 years, the UK National Health Service has benefited from recruitment from LMICs, providing the UK with a rich diaspora of trained health-care professionals with links to LMICs. A grassroots drive to engage with partners in LMICs within the UK has grown from the National Health Service, UK academia, and other organisations. This drive has generated a model that rests on two structures: London Global Cancer Week and the UK Global Cancer Network, providing a high-value foundation for international discussion and collaboration. Starting with a historical perspective, this Series paper describes the UK landscape and offers a potential plan for the future UK's contribution to global cancer control. We also discuss the opportunities and challenges facing UK partnerships with LMICs in cancer control. The UK should harness the skills, insights, and political will from all partners to make real progress.

BACKGROUND: Adolescent overweight and obesity are well documented in high-income countries (HICs). They are also emerging as a global public health concern in low-and middle-income countries (LMICs), yet there is a lack of reliable, national-level data to inform policies and interventions. This study aimed to estimate the prevalence of overweight and obesity and assess associated lifestyle risk factors amongst school-going adolescents in LMICs as well as HICs. METHODS: A total of 282,213 samples were drawn from 89 LMICs and HICs in the 'latest Global School-based Student Health Survey' of school children, aged 11-17 years, during 2003 to 2015, in the six World Health Organisation (WHO) regions. The prevalence of adolescent overweight and obesity were estimated using the WHO BMI-for-age growth standards. A multinomial logistic regression model was employed to estimate the adjusted (age and sex) association of food patterns, physical activity, and sedentary behaviours with adolescent overweight and obesity. RESULTS: The pooled prevalence of overweight and obesity amongst adolescents was 10.12%, and 4.96%, respectively, ranging from 2.40% in Sri Lanka to 29.08% in Niue for overweight and 0.40% in Sri Lanka to 34.66% in the Cook Islands for obesity. Overweight and obesity were associated with unhealthy dietary intake and lifestyles including respectively fast-food intake (adjusted relative risk ratio, RRR = 1.09; 95% CI: 1.05-1.12 and RRR = 1.32; 95% CI: 1.26-1.38), a high level of carbonated soft drinks consumption (RRR = 1.19; 1.12-1.24 and RRR = 1.28; 1.18-1.38), a low level of physical activity (RRR = 1.11; 1.06-1.17 and 1.20; 1.12-1.28), and high level of sedentary behaviours (RRR = 1.33; 1.27-1.39 and RRR = 1.73; 1.63-1.84). Adolescents who consumed vegetables at least two times per day had a lower risk of overweight (22%) and obesity (17%) than those who did not consume vegetables per day. CONCLUSIONS: Adolescent overweight and obesity represent a global public health problem and can possibly track into adult weight status and morbidity. School-based obesity prevention that promotes environmental and policy changes related to healthy dietary practices and active living are urgently needed to curb the trend.

RESUMO

OBJECTIVE: We describe the composition and variation of women's resource strategies in an arid-living Southern African agro-pastoralist society to gain insights into adaptation to climate-change-induced increased aridity. METHODS: Using cross-sectional data from 210 women collected in 2009 across 28 agro-pastoralist villages in Kaokoveld Namibia, we conducted principal-component (PC) analysis of resource variables and constructed profiles of resource strategies from the major PCs. Next, we explored associations between key resource strategies and demographic measures and fitness proxies. RESULTS: The first two PCs accounted for 43% of women's overall resource variation. PC1 reflects women's ability to access market resources via livestock trading, while PC2 captured women's direct food access. We found that market strategies were more common among married women and less common among women who have experienced child mortality. Women with higher subsistence security were more likely to be from the OvaHimba tribe and had a higher risk of gonorrhea exposure. We also qualitatively explored drought-induced pressure on women's livestock. Finally, we show that sexual networks were attenuated during drought, indicating strain on social support. CONCLUSIONS: Our results highlight how agro-pastoralist women manage critical resources in unpredictable environments, and how resource strategies distribute among the women in our study. Goats as a commodity to obtain critical resources suggests that some women have flexibility during drought when gardens fail and cattle die. However, increased aridity and drought may eventually overwhelm husbandry practices in this region.

RESUMO

BACKGROUND: Hand surgeons have the potential to substantially decrease the surgical disability burden in the developing world through educator trips. The Lancet Commission supports contextually driven educator trips grounded in the needs of local hosts, yet few organizations perform a comprehensive assessment of learning interests or the hosting institutions' surgical capacity before the trips. METHODS: The authors adapted the Personnel, Infrastructure, Procedures, Equipment, and Supplies questionnaire, which was modified from the World Health Organization's validated Tool for Situational Analysis to Assess Emergency and Essential Surgical Care. The authors revised each aspect of the questionnaire to reflect items pertinent to upper extremity surgery and hand trauma care. They added sections to gauge self-identified learning needs, local disease burden, operative resources, and current practices. The tool was distributed by means of Qualtrics; descriptive statistics were used to summarize data. The authors analyzed the data for all participants and performed two subgroup analyses to examine variation by regions and countries. RESULTS: The authors received 338 responses from 27 countries. There was wide variability in local surgical disease burden, learning interests, and skill level of upper extremity procedures. Although learners were most interested in learning tendon transfers and microsurgical techniques, the majority did not have adequate infrastructure at their institution to sustain capacity for microvascular procedures. CONCLUSIONS: Needs assessments can gauge how best to provide education during short-term visiting educator trips and optimize its impact in resource-limited settings. Understanding the needs, learning interests, and availability of resources of local learners is imperative to creating a sustainable global surgical workforce.

RESUMO

BACKGROUND: One of the most preventable errors of a surgeon's career is operating on the incorrect surgical site (ICSS). No study in any specialty has ever investigated the incidence of ICSS events in lower-income countries. This study focuses on identifying the occurrence of these events along with an analysis of potential causes leading to these unfortunate events. METHODS: The authors distributed a survey to neurosurgical colleagues from around the world. These surgeons were first asked to identify details about their practice and incidence and personal experience with ICSS in their own careers. At the end of the survey, they responded to questions about their knowledge of safety checklists. RESULTS: In this study there was a 63.4% response rate. When combined with those who participated through various social media platforms, there were 178 responses. The incidence rate for every 10,000 cases performed was found to be 22.8 in the cranial group, 88.6 in the cervical group, and 158.8 in the lumbar procedural group. This study identified that 40% of participants had never learned or experienced the ABCD time-out strategy and that 60% of surgeons did not use intraoperative navigation or imaging in their practices. The error has never been disclosed to the patient in 48% of the ICSS cases. CONCLUSIONS: Due to a lack of application of safety checklist protocol, there is an increased occurrence of ICSS events in lower-income countries. The results of this study demonstrate the necessity of investing time and resources dedicated to avoiding preventable errors.
