RESUMO
Brain organoids are self-organized, three-dimensional (3D) aggregates derived from pluripotent stem cells that have cell types and cellular architectures resembling those of the developing human brain. The current understanding of human brain developmental processes and neurological disorders has advanced significantly with the introduction of this in vitro model. Brain organoids serve as a translational link between two-dimensional (2D) cultures and in vivo models which imitate the neural tube formation at the early and late stages and the differentiation of neuroepithelium with whole-brain regionalization. In addition, the generation of region-specific brain organoids made it possible to investigate the pathogenic and etiological aspects of acquired and inherited brain disease along with drug discovery and drug toxicity testing. In this review article, we first summarize an overview of the existing methods and platforms used for generating brain organoids and their limitations and then discuss the recent advancement in brain organoid technology. In addition, we discuss how brain organoids have been used to model aspects of neurodevelopmental and neurodegenerative diseases, including autism spectrum disorder (ASD), Rett syndrome, Zika virus-related microcephaly, Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD).

INTRODUCTION: Pain is the most common complaint among cancer patients, significantly impairing their health-related quality of life (HRQOL). There is limited evidence on the characteristics of pain among cancer patients in Nepal with low-resource settings. OBJECTIVES: The primary objective of this study was to evaluate the clinical characteristics of pain, factors influencing pain intensity, and the association of pain severity with quality of life (QoL) among cancer patients. Secondary objectives included investigating perceived barriers to pain management and medication adherence among these patients. METHODS: This multi-center, cross-sectional study enrolled adult patients (over 18 years old) with reported cancer diagnoses experiencing pain. Socio-demographic characteristics (e.g., age, gender, educational status), clinical characteristics (e.g. cancer diagnosis, staging), and pain characteristics (e.g., duration, type, location, medicines used for pain management, etc.) were recorded. Outcomes were assessed using the Numeric rating scale (NRS), Pain management Index, European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire, Barriers Questionnaire II, Medication Adherence Rating Scale, and Hospital Anxiety and Depression Scale. RESULTS: Four hundred and eight patients participated in the study. The mean ± SD age was 54.87 ± 15.65, with 226 patients (55.4%) being female. The most common cancer diagnoses were cervical (17.6%), lung (11.8%), and colon/rectum (12.0%) cancers. The most common pain locations were the head and neck (27.0%); a majority (55.6%) reported pain duration of more than 3 months. Nociceptive pain was reported by 42.4% of patients; the mean ± SD of NRS was 4.31 ± 2.69, with 32.4% of patients experiencing moderate pain. Patients with mixed pain type (B = 1.458, p < 0.001) or pain in multiple sites (B = 1.175, p < 0.001), lower Karnofsky Performance Status (KPS) (B = -1.308, p < 0.001), and specific cancer diagnoses such as prostate (B = -2.045, p = 0.002), pancreatic (B = 1.852, p = 0.004), oesophageal (B = 1.674, p = 0.012), and ovarian cancer (B = 1.967, p = 0.047), experienced varying degrees of increased NRS score. The combined chemotherapy and radiotherapy treatment modality was associated with a lower NRS score (B = -0.583, p = 0.017). A significant inverse relationship was observed between pain severity and global health status/QoL (B = -37.36, p < 0.001. Key barriers to pain management included moderate perceptions of physiological effects, communication issues between doctors and patients, and concerns about the harmful effects of pain medicine. The prevalence of non-adherence to pain medications was 13.97%. CONCLUSION: In conclusion, this study highlights the multi-faceted nature of pain management and QoL for cancer patients in Nepal with low-resource settings. These findings underscore the multifactorial nature of pain perception in cancer patients, with mixed pain types, pain in multiple sites, lower KPS, and specific cancer diagnoses, all contributing significantly to pain severity. Additionally, pain severity was associated with declining QoL. These findings contribute valuable insights into the complex aspects of cancer pain and its broader implications for the well-being of patients, offering a foundation for targeted interventions and improved pain management strategies in the context of cancer care in low-resource settings.

Japan's Diovan® /valsartan 'scandal' has received sensational coverage in the nation's media since 2012. Publication of fraudulent research and their subsequent retraction boosted and then curtailed the use of what was a useful therapeutic drug. Some authors of the papers resigned, others disputed the retractions and resorted to legal counsel to protect themselves. One individual, an undeclared Novartis employee involved in the research, was arrested. A complex and virtually unwinnable case was brought against him and Novartis, claiming that data alteration amounted to false advertising, but lengthy criminal court cases resulted in the case failing. Unfortunately, key elements, including conflicts of interest, pharmaceutical company interference in trials of its product, and the role of the institutions involved, have been effectively ignored. The incident also emphasised the fact that Japan's unique society and approach to science does not conform well to international standards. Although the supposed impropriety caused the appearance of a new Clinical Trials Act in 2018, the law has been criticized for being ineffectual and simply increasing clinical trial bureaucracy. This article examines the 'scandal' and identifies where changes must be made to clinical research and the roles of the various stakeholders in Japan to increase public trust in clinical trials and biomedical publications.

BACKGROUND: Afghanistan, a low-income landlocked country, is continuously suffering from domestic war and conflicts; the country struggles to provide quality healthcare services, including affordable medicinal products in the required quantity. Moreover, the quality standards of domestic pharmaceutical companies have not been established yet. One of the internationally recognized guidelines for monitoring manufacturing processes in pharmaceutical companies is Good Manufacturing Practice (GMP), recommended by World Health Organization (WHO). Therefore, this study aimed to assess whether a pharmaceutical company in Kabul, Afghanistan adheres to the GMP standards established by WHO. METHOD: A descriptive cross-sectional study was conducted to assess the WHO-delineated GMP compliance of 25 pharmaceutical companies in Kabul, Afghanistan. The inspection checklist was developed by Afghanistan's National Medicine and Healthcare Products Regulatory Authority (NMHRA) using the WHO-delineated GMP guidelines. In addition, direct observation, interviews with respective delegates, and documentation reviews were conducted to collect research data. RESULT: Only 38.33% (1.14 ± 1.08) of GMP contents were complied. Personnel 66.67% (2 ± 1.15) and materials 58.67% (1.76 ± 1.11) were the most commonly complied components, whereas the product recall 12.98% (0.39 ± 0.85), quality assurance 16.44% (0.49 ± 0.81) and quality control laboratory 28.35% (0.85 ± 1.12) were the least complied ones. CONCLUSION: None of the GMP components was fully adhered to by the pharmaceutical companies in Kabul, Afghanistan. Quality control and assurance should be implemented immediately, including validation and qualification practices.
RESUMO
BACKGROUND: Financial relationships between healthcare professionals and pharmaceutical companies have historically caused conflicts of interest and unduly influenced patient care. However, little was known about such relationship and its effect in clinical practice among specialists in respiratory medicine. METHODS: Based on the retrospective analysis of payment data made available by all 92 pharmaceutical companies in Japan, this study evaluated the magnitude and trend of financial relationships between all board-certified Japanese respiratory specialists and pharmaceutical companies between 2016 and 2019. Magnitude and prevalence of payments for specialists were analyzed descriptively. The payment trends were assessed using the generalized estimating equations for the payment per specialist and the number of specialists with payments. RESULTS: Among all 7,114 respiratory specialists certified as of August 2021, 4,413 (62.0%) received a total of USD 53,547,391 and 74,195 counts from 72 (78.3%) pharmaceutical companies between 2016 and 2019. The median (interquartile range) 4-year combined payment values per specialist were USD 2,210 (USD 715-8,178). At maximum, one specialist received USD 495,332 personal payments over the 4 years. Both payments per specialist and number of specialists with payments significantly increased during the 4-year period, with 7.8% (95% CI: 5.5-9.8; p < 0.001) in payments and 1.5% (95% CI: 0.61-2.4; p = 0.001) in number of specialists with payments, respectively. CONCLUSION: The majority of respiratory specialists had increasingly received more personal payments from pharmaceutical companies for the reimbursement of lecturing, consulting, and writing between 2016 and 2019. These increasing financial relationships with pharmaceutical companies might cause conflicts of interest among respiratory physicians.

Background: Underreporting of adverse drug reactions (ADRs) is common globally, and Nepal is not an exception to this. Health-care professionals (HCPs) play a vital role in reporting ADR during routine practice. Lack of knowledge and awareness about pharmacovigilance and reporting ADRs among HCPs may contribute to underreporting. Objective: The objective of this study was to evaluate the knowledge and perception of HCPs regarding ADR reporting and pharmacovigilance in a tertiary care teaching hospital in, Nepal. Methods: A descriptive cross-sectional study was conducted. A questionnaire was distributed to 215 HCPs (medical doctors, nurses, and pharmacists) between March and September 2018. Knowledge and perception regarding ADR reporting and pharmacovigilance were studied. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0 (IBM Corp, Armonk, New York). Results: The HCPs included 75 medical doctors, 126 nurses, and 14 pharmacists. Majority of the participants were female (67%), and the majority of participants were not aware of pharmacovigilance. Among the participants, pharmacists were found to have better knowledge regarding pharmacovigilance. However, other HCPs (doctors and nurses) strongly agreed about the necessity of having adequate knowledge about pharmacovigilance. Out of 215, 57.7% agreed that the important benefit of reporting ADR was to identify safe drugs and improve patient safety. The main reasons for not reporting were - ADR reporting was not widely promoted by relevant authorities (47%), followed by not knowing where and how to report ADR (34.9%). However, other HCPs (doctors and nurses) strongly agreed about the necessity of having adequate knowledge about pharmacovigilance. Conclusions: The knowledge of HCPs on ADR reporting and pharmacovigilance was poor. Despite a low knowledge of ADR reporting and pharmacovigilance among HCPs, there was a positive perception that ADR reporting is necessary and ADR monitoring system should be established in the hospital. This study also highlights a need for future intervention studies focusing on educating HCPs about ADR and pharmacovigilance.
RESUMO
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by a new species of ß-coronavirus genus named severe acute respiratory syndrome coronavirus 2. The COVID-19 pandemic, which started in late 2019 and continues as at mid-2021, has caused enormous damage to health and lives globally. The urgent public health need has led to the development of vaccines against COVID-19 in record-breaking time. The COVID-19 vaccines have been widely rolled out for the masses by many countries following approval for emergency use by the World Health Organization and regulatory agencies in many countries. In addition, several COVID-19 vaccine candidates are undergoing clinical trials. However, myths, fears, rumors, and misconceptions persist, particularly in regard to adverse events. In this commentary, we describe the adverse events associated with COVID-19 vaccines and discuss why it is essential to have a functional adverse event monitoring system in this context.
RESUMO
BACKGROUND: Unintended pregnancy occurs due to incorrect or inconsistent use of a contraception method. Such pregnancies can create an economic burden on the family, society and nation as a whole. Unintended pregnancy is the underlying cause of abortion which can also result in infertility and maternal death. Adequate knowledge of emergency contraceptive pills (ECPs) and positive attitudes among the community pharmacy practitioners (CPPs) is a prerequisite for timely access of ECP, thus ultimately lessening the incidence of unintended pregnancies. This study intended to explore the knowledge, attitude and practice of CPPs toward ECPs in Kathmandu valley. METHODS: Cross-sectional study conducted in community pharmacies located in three districts of Kathmandu valley. A convenience sampling method was employed to interview CPPs in 227 community pharmacies using a validated questionnaire. Questionnaire assessed the demographic characteristics; knowledge, attitude and dispensing practice of the CPPs. Data were subjected to descriptive and inferential analysis using SPSS 18 (SPSS Inc., Chicago, IL, USA). RESULTS: Approximately 75% of respondents had a good practice on dispensing ECPs, and 70% of them counselled all the users. A significant association (p-value< 0.05) was obtained between the dispensing practice of respondents and their knowledge level. ECP related knowledge was higher among the age group 40-49 years, BPharm degree holders with experience above 10 years and community pharmacies located inside the city and in the Kathmandu district. After adjusting the possible confounder variables, age, degree and district of pharmacy were significantly associated with knowledge. Similarly, respondents' practice towards ECP was higher among the age group 40-49 years with experience above 10 years and community pharmacies located inside the city and in the Kathmandu district. Adjusted for other variables, only community pharmacies located at Kathmandu district was significantly associated with the practice. CONCLUSION: CPPs lacked specific important information on ECP and opined against its' availability as an over-the-counter drug, despite good overall knowledge and positive attitude. Many thought that ECP without prescription would increase promiscuity towards sexual behaviour and result in unsafe sex along with its' repeated use. Hence, training and proper counselling strategies should be afoot to refine the delivery of service by CPPs.

BACKGROUND: Pharmacovigilance (PV) knowledge and attitudes among health care professionals (HCPs) directly affect the practice of PV and reporting of adverse drug reactions (ADRs) in a hospital. The main aim of the study was to assess the impact of an education intervention on the knowledge and attitude of HCPs attached to the regional PV center in an oncology based hospital of Nepal. METHODS: A pre-post intervention questionnaire-based study was conducted amongst HCPs, i.e. nurses and pharmacists of an oncology based hospital of Nepal. A 21-item pretested PV questionnaire (twelve and four statements for assessing knowledge and attitude respectively) was used before and after an educational intervention among 89 HCPs working in the hospital. SPSS version 21.0 was used to analyze pre- and post-survey data with descriptive and inferential statistics. The knowledge and attitude scores before and after educational intervention were analyzed with Wilcoxon rank-sum test. RESULTS: After the educational intervention, the mean score for knowledge about PV and ADR increased from [mean ± S.D] 6.90 ± 2.527 (pre-test) to 11.36 ± 1.189 (post-test, p < 0.001). There were significant improvements after an educational intervention in attitude from 1.80 ± 0.932 (pre-test) to 3.61 ± 0.556 (post-test, p < 0.001). Twenty-one (23.6%) of participants responded that they lacked the time to report ADR, while 12 (13.5%) replied that there was no remuneration for reporting ADR. Approximately 24% of them recommended frequent pharmacovigilance awareness programs via continuing medical education or other similar kinds of workshops for improvement of pharmacovigilance. CONCLUSION: The preliminary findings of this study showed that knowledge and attitude scores were increased following an educational intervention. They also suggested that training on PV and ADR tends to have a positive impact on knowledge and attitude among nurses and pharmacists working at an oncology based hospital in Nepal.

The novel coronavirus disease 2019 (COVID-19) pandemic is a major global threat affecting millions of lives throughout the world physically and psychologically. With the asymptomatic presentation of COVID-19 in many patients and the similarity of its symptoms with the common cold and influenza, the need for accurate information on the disease is very important for its identification and proper management. Accurate information on the disease, its prevention and treatment can be disseminated through drug information centers (DICs). DICs are usually staffed by pharmacists and/or clinical pharmacists/pharmacologists. DICs are a reliable source of current and unbiased information on COVID-19 and its associated complications, including management options for healthcare professionals and the public. In addition to health and drug information, pharmacists working in the DICs can be involved in the management of the patients' health by providing information on home care and safety, medication management of patients with chronic comorbid illnesses, and psychological advice. This article explores the possible additional roles DICs can play, besides providing drug information within the hospital or in the community.

Background: The role of pharmacists in many developed countries has evolved from the traditional practice of dispensing medicines to contributing directly or indirectly to improve patient health outcomes. They are providing hospital services and patient care including services in the emergency department (ED). However, there is limited evidence for pharmacist involvement in the ED from resource-limited countries such as Nepal. Objective: The aim of this study is to discuss the role of pharmacists and highlight the unmet need of pharmacists in ED in Nepal. Methods: A narrative review of existing literature was conducted. Results: The status of ED services in Nepalese hospitals is not yet at a desirable level, and there is limited information about the role of pharmacists in EDs. Evidence obtained from developed nations on the role of pharmacists in EDs suggests that they help in improving patient outcomes by minimizing medication errors, adverse drug reactions, and enhance patient care. Conclusion: The study highlights the need for pharmacists in EDs in resource-limited settings. There is limited evidence of pharmacists' role in EDs from Nepal. Therefore, this study suggests a need for further studies on the possible contribution of pharmacists to ED services in Nepal.
RESUMO
BACKGROUND: With an ageing global population comes major non-communicable disease burden, especially in low-income and middle-income countries. An unknown proportion of this burden is treatable or palliated with surgery. This study aimed to estimate the surgical needs of individuals aged 50 years or older in Nepal. METHODS: A two-stage, 30 randomised cluster by 30 households, community-based survey was performed in Nepal with the validated Surgeons OverSeas Assessment of Surgical Need (SOSAS). Respondents aged older than 50 years were included. After verbal informed consent was obtained, SOSAS collected household demographics, completed a verbal autopsy, and randomly selected household members for verbal head-to-toe examinations for surgical conditions. The Nepal Health Research Council in Kathmandu and the Nationwide Children's Hospital in Columbus, OH, USA, granted ethical approval. FINDINGS: The survey sampled 1350 households, totalling 2695 individuals (97% response rate); 49% were aged 50-59 years, 33% were 60-69 years, and 17% were 70 years and older. Of these, 273 surgical conditions were reported by 507 individuals. A growth or mass (including hernias and goiters) was the most commonly reported potentially surgical condition (25%), injuries and fractures were also common and had the greatest disability. Acquired deformities (13%), incontinence (11%), non-injury wounds (9%), and pelvic organ prolapse were also prevalent. Together, head and neck (24%) and back and extremity conditions (32%) were responsible for more than half of the conditions potentially treatable with surgery. These were followed by genitourinary (28%), abdominal (14%) and chest and breast conditions (2%). Extrapolated nationwide, roughly 1·25 million elderly individuals have a surgically treatable condition (32â150 per 100â000 people). There were 108 deaths in the year before to the survey. 20 (19%) were potentially preventable with surgery. Half of the deaths were due to a growth or mass, 20% to injury, 20% to abdominal pain or distension, and 10% to a non-injury wound. The age-standardised death rate of those with a potentially surgical condition was 24 per 1000 persons for individuals in their 6th decadte, 60 per 1000 for those in their 7th, and 44 per 1000 for those in their 8th. One in five deaths were potentially treatable or palliated by surgery. Literacy and distance to secondary and tertiary health facilities were associated with not receiving care for surgical conditions (p<0·05). INTERPRETATION: Surgical need is largely unmet among elderly individuals in Nepal. Literacy and distance from a capable health facility are the greatest barriers to care. Although verbal examination findings were used as proxies for surgical conditions, the survey tool has been previously validated. Also, there is potential for recall bias with overestimation of tragic deaths and underestimation of unknown or forgotten surgical causes of death and disease. However, this is the most comprehensive evaluation of surgical need in a developing country among the elderly. As the global population ages, there is an increasing need to improve access to surgical services and strengthen health systems to care for this group.

RESUMO
BACKGROUND: Trauma has become a worldwide pandemic. Without dedicated public health interventions, fatal injuries will rise 40% and become the 4th leading cause of death by 2030, with the burden highest in low-income and middle-income countries (LMICs). The aim of this study was to estimate the prevalence of traumatic injuries and injury-related deaths in low-resource countries worldwide, using population-based data from the Surgeons OverSeas Assessment of Surgical Need (SOSAS), a validated survey tool. METHODS: Using data from three resource-poor countries (Nepal, Rwanda, and Sierra Leone), a weighted average of injury prevalence and deaths due to injury was calculated and extrapolated to low-resource countries worldwide. Injuries were defined as wounds from road traffic injuries (bus, car, truck, pedestrian, and bicycle), gunshot or stab or slash wounds, falls, work or home incidents, and burns. The Nepal study included a visual physical examination that confirmed the validity of the self-reported data. Population and annual health expenditure per capita data were obtained from the World Bank. Low-resource countries were defined as those with an annual per capita health expenditure of US$100 or less. FINDINGS: The overall prevalence of lifetime injury for these three countries was 18·03% (95% CI 18·02-18·04); 11·64% (95% CI 11·53-11·75) of deaths annually were due to injury. An estimated prevalence of lifetime injuries for the total population in 48 low-resource countries is 465·7 million people; about 2·6 million fatal injuries occur in these countries annually. INTERPRETATION: The limitations of this observational study with self-reported data include possible recall and desirability bias. About 466 million people at a community level (18%) sustain at least one injury during their lifetime and 2·6 million people die annually from trauma in the world's poorest countries. Trauma care capacity should be considered a global health priority; the importance of integrating a coordinated trauma system into any health system should not be underestimated. FUNDING: None.
RESUMO
BACKGROUND: Herniorrhaphy is one of the most frequently performed general surgical operations worldwide; however, most low-income and middle-income countries (LMICs) are unable to provide this essential surgery resulting in substantial morbidity and mortality. This study aimed to estimate the prevalence of, barriers to care for, and disability from untreated hernias in Nepal. METHODS: A cluster randomised, cross-sectional household survey was performed in Nepal using the validated Surgeons OverSeas Assessment of Surgical (SOSAS) tool. Sample size was based on a pilot study that reported a 5% prevalence of unmet surgical need. 15 clusters consisting of 30 households each were sampled proportional to population. In each, two randomly selected family members underwent a verbal head-to-toe physical examination and answered questions about barriers to care and disability. FINDINGS: The survey sampled 1350 households, totalling 2695 individuals (97% response rate). 1434 (53%) of responders were men and 1·5% (95% CI 1·8-4·0) had a mass or swelling in the groin at time of survey. The age-standardised rate for inguinal hernias in men ranged from 1144 per 100 000 persons between age 5 and 49 years and 2941 per 100 000 persons aged 50 years and older. 29 respondents were not able to have surgery due to lack of surgical services (nine; 31%), fear or mistrust of the surgical system (nine; 31%), and inability to afford care (six; 21%). 10 respondents (20%) were unable to work as previous or perform self-care due to their hernia. INTERPRETATION: Despite the lower than expected prevalence of inguinal hernias, more than 300â000 people in Nepal are currently in need of herniorrhaphy. In view that essential surgery is a necessary component in health systems, the prevalence of inguinal hernias and the cost-effectiveness of herniorrhaphy, this disease is an important target for LMICs planning surgical capacity improvements.

RESUMO
BACKGROUND: Surgical care needs in low-resource countries are increasingly recognised as an important aspect of global health, yet data for the size of the problem are insufficient. The Surgeons OverSeas Assessment of Surgical Need (SOSAS) is a population-based cluster survey previously used in Nepal, Rwanda, and Sierra Leone. METHODS: Using previously published SOSAS data from three resource-poor countries (Nepal, Rwanda, and Sierra Leone), a weighted average of overall prevalence of surgically treatable conditions was estimated and the number of deaths that could have been avoided by providing access to surgical care was calculated for the broader community of low-resource countries. Such conditions included, but were not limited to, injuries (road traffic incidents, falls, burns, and gunshot or stab wounds), masses (solid or soft, reducible), deformities (congenital or acquired), abdominal distention, and obstructed delivery. Population and health expenditure per capita data were obtained from the World Bank. Low-resource countries were defined as those with a per capita health expenditure of US$100 or less annually. The overall prevalence estimate from the previously published SOSAS data was extrapolated to each low-resource country. Using crude death rates for each country and the calculated proportion of avoidable deaths, a total number of deaths possibly averted in the previous year with access to appropriate surgical care was calculated. FINDINGS: The overall prevalence of surgically treatable conditions was 11·16% (95% CI 11·15-11·17) and 25·6% (95% CI 25·4-25·7) of deaths were potentially avoidable by providing access to surgical care. Using these percentages for the 48 low-resource countries, an estimated 288·2 million people are living with a surgically treatable condition and 5·6 million deaths could be averted annually by the provision of surgical care. In the Nepal SOSAS study, the observed agreement between self-reported verbal responses and visual physical examination findings was 94·6%. Such high correlation helps to validate the SOSAS tool. INTERPRETATION: Hundreds of millions of people with surgically treatable conditions live in low-resource countries, and about 25% of the mortality annually could be avoided with better access to surgical care. Strengthening surgical care must be considered when strengthening health systems and in setting future sustainable development goals. FUNDING: None.
RESUMO
BACKGROUND: The Surgeons OverSeas assessment of surgical need (SOSAS) tool, a population-based survey on surgical conditions in low- and middle-income countries (LMICs), was performed in Sierra Leone and Rwanda. This pilot study in Nepal is the initial implementation of the SOSAS survey in South Asia. METHODS: A pilot study of SOSAS, modified for Nepal's needs and reprogrammed using mobile data collection software, was undertaken in Pokhara in January 2014. Cluster randomized sampling was utilized to interview 100 individuals in 50 households within two wards of Pokhara, one rural and one urban. The first portion of the survey retrieved demographic data, including household members and time to nearest health facilities. The second portion interviewed two randomly selected individuals from each household, inquiring about surgical conditions covering six anatomical regions. RESULTS: The pilot SOSAS in Nepal was easily completed over 3 days, including training of 18 Nepali interns over 2 days. The response rate was 100 %. A total of 13 respondents had a current surgical need (face 4, chest 1, back 1, abdomen 1, groin 3, extremity 3), although eight reported there was no need for surgical care. Five respondents (5 %) had a current unmet surgical need. CONCLUSION: The SOSAS pilot study in Nepal was successfully conducted, demonstrating the feasibility of performing SOSAS in South Asia. The estimated 5 % current unmet surgical need will be used for sample size calculation for the full country survey. Utilizing and improving on the SOSAS tool to measure the prevalence of surgical conditions in Nepal will help enumerate the global surgical burden of disease.
