Burns in Nepal: A population based national assessment

BACKGROUND Burns are ranked in the top 15 leading causes of the burden of disease globally, with an estimated 265,000 deaths annually and a significant morbidity from non-fatal burns, the majority located in low and middle-income countries. Given that previous estimates are based on hospital data, the purpose of this study was to explore the prevalence of burns at a population level in Nepal, a low income South Asian country. METHODS A cluster randomized, cross sectional countrywide survey was administered in Nepal using the Surgeons OverSeas Assessment of Surgical Need (SOSAS) from May 25th to June 12th, 2014. Fifteen of the 75 districts of Nepal were randomly chosen proportional to population. In each district, three clusters, two rural and one urban, were randomly selected. The SOSAS survey has two portions: the first collects demographic data about the households access to healthcare and recent deaths in the household; the second is structured anatomically and designed around a representative spectrum of surgical conditions, including burns. RESULTS In total, 1350 households were surveyed with 2695 individuals with a response rate of 97%. Fifty-five burns were present in 54 individuals (2.0%, 95% CI 1.5-2.6%), mean age 30.6. The largest proportion of burns was in the age group 25-54 (2.22%), with those aged 0-14 having the second largest proportion (2.08%). The upper extremity was the most common anatomic location affected with 36.4% of burns. Causes of burns included 60.4% due to hot liquid and/or hot objects, and 39.6% due to an open fire or explosion. Eleven individuals with a burn had an unmet surgical need (20%, 95% CI 10.43-32.97%). Barriers to care included facility/personnel not available (8), fear/no trust (1) and no money for healthcare (2). CONCLUSION Burns in Nepal appear to be primarily a disease of adults due to scalds, rather than the previously held belief that burns occur mainly in children (0-14) and women and are due to open flames. This data suggest that the demographics and etiology of burns at a population level vary significantly from hospital level data. To tackle the burden of burns, interventions from all the public health domains including education, prevention, healthcare capacity and access to care, need to be addressed, particularly at a community level. Increased efforts in all spheres would likely lead to a significant reduction of burn-related death and disability.

Self-reported Determinants of Access to Surgical Care in 3 Developing Countries

IMPORTANCE Surgical care is recognized as a growing component of global public health. OBJECTIVE To assess self-reported barriers to access of surgical care in Sierra Leone, Rwanda, and Nepal using the validated Surgeons OverSeas Assessment of Surgical Need tool. DESIGN, SETTING, AND PARTICIPANTS Data for this cross-sectional, cluster-based population survey were collected from households in Rwanda (October 2011), Sierra Leone (January 2012), and Nepal (May and June 2014) using the Surgeons OverSeas Assessment of Surgical Need tool. MAIN OUTCOMES AND MEASURES Basic demographic information, cost and mode of transportation to health care facilities, and barriers to access to surgical care of persons dying within the past year were analyzed. RESULTS A total of 4822 households were surveyed in Nepal, Rwanda, and Sierra Leone. Primary health care facilities were commonly reached rapidly by foot (>70%), transportation to secondary facilities differed by country, and public transportation was ubiquitously required for access to a tertiary care facility (46%-82% of respondents). Reasons for not seeking surgical care when needed included no money for health care (Sierra Leone: n = 103; 55%), a person dying before health care could be arranged (all countries: 32%-43%), no health care facility available (Nepal: n = 11; 42%), and a lack of trust in health care (Rwanda: n = 6; 26%). CONCLUSIONS AND RELEVANCE Self-reported determinants of access to surgical care vary widely among Sierra Leone, Rwanda, and Nepal, although commonalities exist. Understanding the epidemiology of barriers to surgical care is essential to effectively provide surgical service as a public health commodity in developing countries.

An estimate of hernia prevalence in Nepal from a countrywide community survey

BACKGROUND Herniorrhaphy is one of the most frequently performed general surgical operations worldwide. However, most low- and middle-income countries (LMICs) are unable to provide this essential surgery to the general public, resulting in considerable morbidity and mortality. This study aimed to estimate the prevalence, barriers to care and disability of untreated hernias in Nepal. METHODS Nepal is a low-income country in South Asia with rugged terrain, infrastructure deficiencies and a severely under-resourced healthcare system resulting in substantial unmet surgical need. A cluster randomized, cross-sectional household survey was performed using the validated Surgeons OverSeas Assessment of Surgical (SOSAS) tool. Fifteen randomized clusters consisting of 30 households with two randomly selected respondents each were sampled to estimate surgical need. The prevalence of and disability from groin hernias and barriers to herniorrhaphy were assessed. RESULTS The survey sampled 1350 households, totaling 2695 individuals (97% response rate). There were 1434 males (53%) with 1.5% having a mass or swelling in the groin at time of survey (95% CI 1.8-4.0). The age-standardized 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 age≥50 years. Extrapolating nationally, there are nearly 310,000 individuals with groin masses and 66,000 males with soft/reducible groin masses in need of evaluation in Nepal. Twenty-nine respondents were not able to have surgery due to lack of surgical services (31%), fear or mistrust of the surgical system (31%) and inability to afford care (21%). Twenty percent were unable to work as previous or perform self-care due to their hernia. CONCLUSIONS Despite the lower than expected prevalence of inguinal hernias, hundreds of thousands of people in Nepal are currently in need of surgical evaluation. Given 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.

Surgical care needs of low-resource populations: an estimate of the prevalence of surgically treatable conditions and avoidable deaths in 48 countries.

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.

Surgical need in an aging population: A cluster-based household survey in Nepal

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 Childrens 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 (32 150 per 100 000 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.

Injury prevalence and causality in developing nations: Results from a countrywide population-based survey in Nepal

BACKGROUND With an aging global population comes an obligate and substantial burden of noncommunicable disease, especially in low- and middle-income countries. An unknown proportion of this burden is treatable with surgical expertise. For health system planning, this study aimed to estimate the operative needs of individuals older than 50 of age years in Nepal. METHODS A 2-stage, cluster randomized, community-based survey was performed in Nepal using the validated Surgeons OverSeas Surgical Assessment Survey (SOSAS). SOSAS collects household demographics and selects household members randomly for verbal, head-to-toe examinations for surgical conditions; moreover, SOSAS also completes a verbal autopsy for deaths in the preceding year. Only respondents older than 50 years were included in the analysis. RESULTS The survey sampled 1,350 households, totaling 2,695 individuals (97% response rate). Of these, 273 surgical conditions were reported by 507 persons ages ≥ 50 years. Extrapolating, there are potentially 2.1 million people older than 50 years of age with surgically treatable conditions who need care in Nepal (95% confidence interval 1.8-2.4 million; 46,000-62,600 per 100,000 persons). One in 5 deaths was potentially treatable or palliated by surgical care. Although growths or masses (including hernias and goiters) were the surgical condition reported most commonly (25%), injuries and fractures also were common and associated with the greatest disability. Literacy and distance to secondary and tertiary health facilities were associated with lack of care for operative conditions (P < .05). CONCLUSION There is a large, unmet surgical need among the elderly in Nepal. Low literacy and distance from a capable health facility are the greatest barriers to care. As the global population ages, there is an increasing need to improve surgical services and strengthen health systems to care for this group.

Injury assessment in three low-resource settings: a reference for worldwide estimates

BACKGROUND Traumatic injury affects nearly 5.8 million people annually and causes 10% of the worlds deaths. In this study we aimed to estimate injury prevalence, to describe risk-factors and mechanisms of injury, and to estimate the number of injury-related deaths in Nepal, a low-income South Asian country. METHODS A cluster randomized, cross-sectional nationwide survey using the Surgeons OverSeas Assessment of Surgical Need tool was conducted in Nepal in 2014. Questions were structured anatomically and designed around a representative spectrum of operative conditions. Two-stage cluster sampling was performed: 15 of 75 districts were chosen randomly proportional to population; within each district, after stratification for urban and rural populations, 3 clusters were randomly chosen. Injury-related results were analyzed. RESULTS A total of 1,350 households and 2,695 individuals were surveyed verbally, with a response rate of 97%. A total of 379 injuries were reported in 354 individuals (13.1%, 95% confidence interval 11.9-14.5%), mean age of 32.6. The most common mechanism of injury was falls (37.5%), road traffic injuries (19.8%), and burns (14.2%). The most commonly affected anatomic site was the upper extremity (42.0%). Of the deaths reported in the previous year, 16.3% were injury-related; 10% of total deaths may have been averted with access to operative care. CONCLUSION This study provides baseline data on the epidemiology of traumatic injuries in Nepal and is the first household-based countrywide assessment of injuries in Nepal. These data provide valuable information to help advise policymakers and government officials for allocation of resources toward trauma care.

Backlog and burden of fractures in Sierra Leone and Nepal: Results from nationwide cluster randomized, population-based surveys

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 worlds 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.
