Injury is recognized globally as one of the top ten causes of illness and death, and violent acts, including those that occur during war and civil conflict, rank among the ten leading contributors to injury worldwide. The burden is not distributed evenly. In the sub-Saharan African region, fatality from injury is among the highest in the world, driven by a combination of interpersonal violence, communal clashes, military violence, armed robbery, and political conflict. Somalia, after more than three decades of instability, exemplifies this pattern, yet the country has historically lacked the kind of hospital-based injury surveillance that informs trauma system design elsewhere. The MSTH study was designed in part to address that gap by capturing data prospectively rather than reconstructing events from retrospective charts.

The study enrolled all patients who arrived at the emergency department of MSTH with gunshot wounds between June 1, 2024, and December 31, 2024. Data were collected prospectively from both electronic and paper-based medical records using a standardized data collection form designed specifically for the investigation. This approach allowed the research team, led by Abdullahi Ahmed Ahmed with colleagues Abdishakur Mohamed Abdirahman and Sahara Ali Yusuf, to document demographic characteristics, injury patterns, anatomical distribution of wounds, treatment provided, and short-term outcomes in a systematic fashion. Because the hospital functions as one of the principal referral and training centers in the Somali capital, its emergency department sees a substantial share of the city’s most serious trauma.

The demographic and circumstantial profile of the victims reflects the realities of urban violence in Mogadishu. Among patients whose status could be classified, soldiers represented the largest single group, accounting for 30.0 percent of cases, or 45 individuals. Passengers, people injured while traveling, made up 18.7 percent, or 28 cases, a figure that underscores how ordinary movement through the city can place civilians in the line of fire. Civilians grouped under the category of others formed the largest overall share at 34.0 percent, or 51 patients. Taken together, the classification shows that while combatants are heavily represented, the majority of those shot were not active participants in hostilities but people caught in the crossfire of insurgent attacks, crossfire incidents, and other forms of armed violence.

The anatomical pattern of injuries provides important clues about both the mechanisms of wounding and the demands placed on surgical services. A striking finding was the frequency of long bone fractures: 18 percent of cases involved comminuted fractures of the femur, tibia, humerus, or other major limb bones. The authors note that this proportion is higher than the 12 percent documented in Kenya and similar to recent findings from Nigeria and Uganda, suggesting that high-velocity injuries and close-range discharges contribute to severe skeletal destruction in the Somali context. Comminuted fractures, in which the bone shatters into multiple fragments, typically require complex orthopedic intervention, prolonged hospitalization, and often leave patients with lasting functional impairment, making their prevalence a marker of both injury severity and future disability burden.

Traumatic brain injuries were documented in 8.0 percent of cases, or 12 patients. Head wounds from firearms carry particularly grave prognoses, and their management in a resource-constrained environment poses formidable challenges, from imaging capacity to neurosurgical expertise. The presence of traumatic brain injury in roughly one in twelve gunshot patients highlights the need for rapid triage, appropriate imaging, and clear protocols for when operative intervention is feasible and when palliative care is the only realistic option. The study’s documentation of these injuries adds to the growing evidence base on the spectrum of firearm trauma in conflict-affected African settings.

Perhaps the most encouraging headline finding concerns survival among those who reach hospital care. Only one death occurred in the emergency department, corresponding to an overall emergency department mortality of 0.7 percent. Intensive care unit admissions comprised 12.7 percent of the cohort, indicating that a meaningful minority of patients required advanced organ support after initial resuscitation. In addition, three patients, or 2.0 percent, left against medical advice, a phenomenon common in settings where families face financial constraints, security concerns, or distrust of hospital care. The authors explicitly contrast their low emergency department mortality with the substantially higher figures reported from other conflict zones, including up to 9.2 percent in the Democratic Republic of the Congo and between 5 and 10 percent in parts of Sudan.

That comparison deserves careful interpretation. A low in-department mortality does not necessarily mean that gunshot trauma is less lethal in Mogadishu overall; it may reflect selection effects, in which the most severely injured patients die before ever reaching the emergency department, or differences in transport times, prehospital care, and the case mix that survives to presentation. The authors acknowledge precisely this limitation, noting that the single-hospital, prospective design may not fully represent broader epidemiological trends across Somalia and cannot capture patients who die before reaching hospital care or who never access formal medical services at all. Prehospital variables, including the type of weapon used, the intent behind the shooting, and the relationship between shooter and victim, were insufficiently documented, limiting the contextual interpretation of injury patterns and outcomes.

Another significant gap the study identifies is the absence of standardized long-term outcome data. Emergency department mortality is a crude and early endpoint; it says nothing about whether patients regain mobility after complex limb fractures, recover cognitive function after brain injuries, or return to work and family life. The authors argue that this lack of longitudinal follow-up underscores an important deficiency in trauma research in the region and highlights the need for prospective longitudinal studies assessing functional recovery, disability, and quality of life after gunshot injury. Without such data, health planners cannot accurately estimate the chronic burden of firearm violence, including the rehabilitation services, prosthetics, and psychosocial support that survivors require.

Looking forward, the research team calls for a new generation of injury surveillance built on multicenter, registry-based, and prospective designs that integrate data from emergency medical services, hospitals, and law enforcement. Such an integrated system would allow Somalia to move beyond single-site snapshots toward a national picture of firearm injury, one that could inform targeted prevention strategies, from conflict mediation and community policing to weapon control measures and improved prehospital care. The MSTH study, modest in scope but rigorous in method, demonstrates that high-quality prospective trauma data can be collected even in one of the world’s most challenging security environments. Its findings, that most gunshot victims survive to leave the emergency department, that soldiers and civilians alike bear the burden of injury, and that severe limb fractures and brain injuries impose a substantial surgical load, offer both reassurance about the resilience of the trauma system and a clear roadmap for the research and policy work that must follow.

The study, published in the Journal of Emergency and Disaster Medicine, drew on two decades of data from the National Electronic Injury Surveillance System, or NEISS, a probability sample of 100 hospitals operated by the United States Consumer Product Safety Commission that monitors emergency department visits involving consumer products. Because NEISS samples roughly 100 hospitals out of more than 5,000 with emergency departments, each recorded encounter carries a statistical weight that allows researchers to estimate national incidence. The research team searched the database from 2005 through 2024, casting a wide net that included common misspellings such as machette and masheti, and then manually reviewed every candidate case to exclude encounters in which the word appeared but the machete was not the true mechanism of injury. That screening process reduced an initial pool of 1,762 cases to 1,525 verified machete-related injuries, and the weighted analysis transformed those records into a striking national estimate: approximately 73,918 emergency department presentations over 20 years, with a 95 percent confidence interval spanning roughly 56,900 to 90,900 visits.

The demographic profile of the injured population is remarkably distinct from that of other consumer product injuries. Nearly 91 percent of the cases involved men, and young adults between 18 and 34 years old accounted for more than a third of all injuries, a pattern the researchers attribute to higher occupational and recreational exposure in this group. At the opposite extreme, female children aged 0 to 4 were almost entirely spared, with only a single case identified across the entire 20-year period. Race was recorded for about 69 percent of encounters, among which 81.8 percent of patients were White, 8.0 percent Black, 7.4 percent multiracial, and the remainder distributed across other categories. Review of the free-text injury narratives suggested that many of these accidents occurred during routine activities such as yard work, vegetation clearing, or tool maintenance, implying that a substantial proportion were unintentional rather than the result of assaults, though the study’s authors caution that intent cannot be reliably determined from brief surveillance narratives.

Temporal patterns tell an equally vivid story. Injuries clustered on weekends, with Saturdays accounting for 20.9 percent of cases and Sundays 18.0 percent, and they surged during the warm months between May and September, which together produced 58.4 percent of all cases over the study period. Annual incidence peaked in 2017 and again in 2020, with the highest rate per 100,000 recorded emergency department visits reaching 36 in 2020. The 2020 spike is particularly suggestive: the COVID-19 pandemic drove many Americans outdoors, and other research has documented increases in outdoor recreational injuries during the summer of 2020. The authors propose that more people were wielding machetes for landscaping, trail clearing, and campsite maintenance during lockdowns, though they emphasize that such interpretations remain hypothesis-generating rather than definitive.

When it comes to the anatomy of the injuries themselves, the numbers are both precise and sobering. Lacerations dominated, accounting for 91.8 percent of all primary diagnoses, which is unsurprising given the machete’s sharp design. Fractures made up 2.1 percent of cases, and amputations and avulsions together represented 2.4 percent. Fingers were the single most commonly injured body part, comprising 37.9 percent of all injuries, an estimated 28,000 national cases over two decades, with the index finger involved in 11.2 percent of injuries and the thumb in 9.2 percent. The lower leg, excluding knee and ankle, accounted for 17.9 percent of injuries, and the hand itself, exclusive of digits, another 15.7 percent. Compared with other sharp tool injuries, which tend to concentrate in the hands, machete wounds appear more distributed across the body, a pattern the researchers liken to chainsaw trauma. They speculate that the follow-through of a heavy swing in an outdoor setting can bring the blade into unintended contact with the legs, though the surveillance data cannot confirm this mechanism directly.

One of the study’s most intriguing findings concerns laterality. Among the 859 cases, or 57.7 percent, in which narratives described which side of the body was hurt, left-sided injuries predominated at 59.0 percent versus 40.7 percent right-sided, with only two bilateral encounters. The skew was concentrated entirely in the upper extremities: left-sided hand and finger injuries occurred 62.3 percent of the time, left wrist injuries 62.5 percent, and left forearm injuries a striking 72.3 percent. Lower leg injuries, by contrast, were almost perfectly symmetrical, split 50.7 percent left to 49.3 percent right. The pattern mirrors prior literature on sharp tool trauma and is commonly attributed to the involvement of the non-dominant hand, which typically holds or stabilizes the material being cut. Because NEISS does not record hand dominance, the authors note that this explanation, while plausible, remains speculative.

Perhaps the study’s most methodologically valuable contribution is its demonstration of what structured surveillance coding misses. NEISS permits only a single primary diagnosis per encounter, so when a machete sliced through skin, tendon, nerve, and artery simultaneously, the coded diagnosis might simply read laceration. Narrative review uncovered 32 cases in which tendon, nerve, or arterial injuries were described in the text yet coded only as lacerations, along with 28 cases documenting flexor or extensor tendon involvement despite the absence of a tendon injury code in the system. The clinical significance of these hidden injuries is underscored by the disposition data: 48 cases required hospital admission for further management, eight more were treated and transferred to other facilities, and 3.0 percent of all patients overall required admission or transfer. Most patients, 95.6 percent, were treated and released, and a small 1.4 percent left against medical advice. No fatalities appeared in the dataset, but the depth and complexity of the tissue damage documented in the narratives make clear that these are far from trivial wounds.

The authors are candid about the limitations inherent in their approach. NEISS is a stratified probability sample, and rare injury mechanisms like machete trauma are especially vulnerable to sampling variability; a single hospital in a warm-weather agricultural state entering or leaving the surveillance network could sharply shift the national estimate for a given year. Annual fluctuations should therefore be read cautiously. The database also does not directly code injury intent, hand dominance, or long-term outcomes, leaving several of the study’s interpretations necessarily descriptive. Yet these constraints do not diminish the central finding that machete injuries constitute a persistent and nontrivial burden on American emergency care, one that has received almost no systematic attention until now.

The findings also point toward concrete prevention strategies. The overwhelming predominance of hand and finger injuries supports educational campaigns emphasizing proper grip, cutting technique, and situational awareness. The frequency of severe lacerations, fractures, and amputations argues for cut-resistant gloves and lower-extremity protective equipment, particularly for occupational and recreational users. Retailers and manufacturers could contribute through improved safety labeling and user guidance, much as has been done for chainsaws and other power tools, and community and workplace programs could reinforce safe tool handling and secure storage among high-risk groups such as young adult men and outdoor workers. Hospital planners, meanwhile, might use the weekend and summer peaks to anticipate demand for hand surgery and trauma resources.

Taken together, the study transforms an anecdote-driven topic into a quantifiable public health concern and showcases the power of narrative-enhanced surveillance for characterizing complex extremity trauma. Nearly 74,000 emergency department visits over two decades is a small number relative to the totality of American injuries, but each represents a patient whose grip, swing, or footing failed for a moment with a two-foot blade in hand. The researchers call for continued national surveillance, investigations into long-term functional outcomes and disability after these injuries, analysis of violence-related machete trauma using registries and law enforcement data, and evaluation of educational interventions for safe tool use. For a tool so widely available and so rarely studied, the message of the data is simple: the machete deserves more respect, and more attention, than the injury statistics have historically allowed.

The technical architecture of NDIC rests on Denmark’s long-standing tradition of nationwide administrative and health registries, all linked through the unique Civil Personal Register number assigned to every resident at birth or upon immigration. This personal identifier functions as the key that allows individual-level records to be joined across central registries with near-complete accuracy. The cohort draws its primary injury data from the Danish National Patient Register, which records all inpatient admissions, outpatient visits and emergency department contacts across both public and private hospitals, spanning somatic and psychiatric care. Injury-related deaths are identified through the Danish Register of Causes of Death, where each fatality is categorised by manner of death as natural, accident, suicide, violence or homicide, or undetermined following autopsy. Because Danish healthcare is tax-funded and free at the point of use, socioeconomic barriers to seeking care are reduced, which supports the completeness of the register-based capture of injury events.

The classification machinery underlying the cohort is deliberately standardised. Diagnoses are recorded using the Danish Medical Classification System, known as SKS, which incorporates the World Health Organization’s tenth revision of the International Classification of Diseases. Injury codes from ICD-10 Chapter XIX, spanning DS00 to DT98, cover physical harm to every major body region as well as burns, corrosions, frostbite, poisonings, complications of medical procedures and long-term sequelae of injuries. Chapter XX codes, DX60 through Y09, classify intentional self-harm, assaults and other external causes. External circumstances are recorded using the NOMESCO Classification of External Causes of Injuries, a Nordic standard translated into SKS as the EUA to EUZ code range. These codes specify the activity the injured person was engaged in, such as sport or paid work, the place of occurrence, such as home, school or road, and the mode of injury, such as a fall or transport accident. For traffic incidents, reporting rules also mandate the transport modes of the injured person and any counterpart, distinguishing for example a cyclist from a passenger car occupant or pedestrian.

Identifying a genuine injury incident within routine administrative data is far from trivial, and the cohort profile lays out the operational logic in detail. Each hospital contact in the National Patient Register carries a reason for contact, which since 2010 has been mandatory for acute somatic encounters and must be coded as an accident, an act of violence, or a suicide attempt when applicable. From early 2019, intentional self-harm was introduced as a distinct reason for contact, whereas before that date self-harm was recorded under illness and cannot be captured through the reason-for-contact field, a structural discontinuity the researchers flag explicitly. A contact qualifies for inclusion in NDIC if it carries any injury reporting code, or a relevant reason for contact, or an action diagnosis in the ranges DX60 to DX99 or DY0 to DY09. Because a single injury episode often generates multiple registrations as patients move through emergency departments, admissions and outpatient clinics, the cohort designates a single key contact per incident and links subsequent contacts into individual incident trajectories, while allowing individuals to accumulate multiple incidents over time. Deaths classified as accident, suicide, or violence or homicide complete the picture, although fatalities can only be identified for registered residents.

The analytical yield of the resource is already substantial. Between 2010 and 2022 the researchers identified 7,217,351 primary injury contacts and 26,871 injury-related deaths. Incidence rates were computed as the number of new events divided by the mid-year population, an accepted approximation of person-time in large dynamic populations, with exact 95 percent confidence intervals derived from the Poisson distribution using chi-square limits. The headline finding is a gradual decline in overall injury incidence from 113.3 per 1,000 person-years in 2010 to 94.4 in 2019, followed by a sharp drop in 2020 coinciding with the COVID-19 pandemic and a partial rebound in subsequent years. Men consistently sustained more injuries than women, with incidence rates between 16.7 and 24.2 percent higher across the period. Mortality told a starker story: men were between 49.7 and 66.2 percent more likely than women to die from an injury, while the overall mortality rate remained relatively stable at 34.2 to 38.0 deaths per 100,000 person-years throughout the study window.

Stratification by age and sex reveals patterns with direct preventive implications. Among women, the highest incidence rates occurred in girls aged 0 to 15 years, ranging from 116.3 to 145.9 per 1,000 person-years, followed by women aged 75 and older at 106.7 to 141.0, and young women aged 16 to 29 at 88.1 to 131.3, all three groups showing declining trends over time and a marked pandemic-era drop among the young. Women aged 30 to 74 sat at much lower and more stable rates of roughly 57 to 65. Among men, boys aged 0 to 15 recorded rates of 139.7 to 171.7 and carried the highest rate in 2022 at 151.5, while men aged 16 to 29 peaked at 195.5 in 2010, declined 26.8 percent to 143.2 by 2015, and remained comparatively stable thereafter aside from the pandemic dip. In a notable reversal of the overall sex pattern, women aged 75 and older consistently exhibited higher injury incidence than men of the same age, while rates were similar between the sexes at 65 to 74 years, underscoring the particular vulnerability of the oldest women, most plausibly linked to falls and fragility.

Geography matters as much as demography. When the researchers stratified incidence by the five Danish regions, they found striking disparities that persisted even after national reporting guidelines were applied uniformly. The Region of Southern Denmark recorded the highest rate in 2010 at 136.4 per 1,000 person-years, falling to around 119.4 by 2014, while the Capital Region declined from 113.8 to 97.0 and Central Denmark from 107.7 to 70.8. The North Denmark Region moved against the trend, rising from 51.0 to 66.0 over the same period, and Region Zealand dipped and then returned to roughly its 2010 level. From 2015 onwards all five regions stabilised with minor fluctuations, and by 2022 the lowest rates were found in Central and North Denmark at 60.5 to 73.1, while Region Zealand reached 113.8 and the Southern and Capital Regions hovered just above 103. The authors are careful to note that such regional gradients may partly reflect differences in healthcare organisation rather than true differences in injury occurrence, since residents of areas far from emergency departments are less likely to attend hospital for the same injury.

That caveat points to the cohort’s central methodological tension, which the profile addresses candidly. NDIC captures only injuries that result in hospital contact or death, meaning minor events treated solely by general practitioners, out-of-hours services, or on-site prehospital care are invisible, and previous self-reported data suggest only about half of all injuries in Denmark reach a hospital setting. Care-seeking behaviour therefore introduces residual selection that may vary geographically with distance to acute care. Misclassification risks also arise from variation in diagnostic and coding practices across clinicians, hospitals and time, with some institutions applying structured routines that generate rich contextual detail while others record only the mandatory minimum. The coding framework itself imposes structural limits, since coders cannot capture circumstances for which no adequate category exists. Yet the compensating strengths are considerable: nationwide population-based coverage, freedom from the selection biases of restricted cohorts or surveys, standardised international coding that enables cross-national comparison through the European Injury Data Base, and statistical power that renders confidence intervals almost invisible at plotted scale for incidence analyses.

The design also anticipates sophisticated downstream research. Through linkage on the Civil Personal Register number, cohort members can be connected to education registers, labour market and income registers, population statistics, prescribed medication records and healthcare utilisation data, enabling sociodemographic analyses of inequalities alongside studies of immigration status, family structure and housing. The longitudinal structure supports at least one year of follow-up after each incident, opening the door to survival analysis of time-to-event outcomes, causal inference methods for evaluating preventive interventions, and prediction modelling to identify high-risk populations. The researchers envision applications across the life course, from childhood injury prevention and workplace accidents among working-age adults to falls among the elderly, as well as mechanism-specific studies of traffic accidents, poisonings, drownings, burns, sports and occupational injuries. Data are held pseudonymously on a secure Statistics Denmark server, all analyses were conducted in R version 4.5.2 using the tidyverse, and the cohort is currently updated through 2022 with plans for annual or biennial updates, positioning NDIC as a durable foundation for evidence-based injury prevention in Denmark and a benchmark for register-based injury epidemiology internationally.
