Endeshaw D, Delie AM, Adal O, Tareke AA, Bogale EK, Anagaw TF, Tiruneh MG, Fenta ET. Mortality and its predictors in abdominal injury across sub-Saharan Africa: systematic review and meta-analysis. BMC Emerg Med 2024; 24:57. [PMID: 38605305 PMCID: PMC11008034 DOI: 10.1186/s12873-024-00982-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Accepted: 04/03/2024] [Indexed: 04/13/2024] Open
Abstract
BACKGROUND Abdominal injuries exert a significant impact on global morbidity and mortality. The aggregation of mortality data and its determinants across different regions holds immense importance for designing informed healthcare strategies. Hence, this study assessed the pooled mortality rate and its predictors across sub-Saharan Africa. METHOD This meta-analysis employed a comprehensive search across multiple electronic databases including PubMed, Africa Index Medicus, Science Direct, and Hinari, complemented by a search of Google Scholar. Subsequently, data were extracted into an Excel format. The compiled dataset was then exported to STATA 17 statistical software for analysis. Utilizing the Dersimonian-Laird method, a random-effect model was employed to estimate the pooled mortality rate and its associated predictors. Heterogeneity was evaluated via the I2 test, while publication bias was assessed using a funnel plot along with Egger's, and Begg's tests. RESULT This meta-analysis, which includes 33 full-text studies, revealed a pooled mortality rate of 9.67% (95% CI; 7.81, 11.52) in patients with abdominal injuries across sub-Saharan Africa with substantial heterogeneity (I2 = 87.21%). This review also identified significant predictors of mortality. As a result, the presence of shock upon presentation demonstrated 6.19 times (95% CI; 3.70-10.38) higher odds of mortality, followed by ICU admission (AOR: 5.20, 95% CI; 2.38-11.38), blunt abdominal injury (AOR: 8.18, 95% CI; 4.97-13.45), post-operative complications (AOR: 8.17, 95% CI; 4.97-13.44), and the performance of damage control surgery (AOR: 4.62, 95% CI; 1.85-11.52). CONCLUSION Abdominal injury mortality is notably high in sub-Saharan Africa. Shock at presentation, ICU admission, blunt abdominal injury, postoperative complications, and use of damage control surgery predict mortality. Tailored strategies to address these predictors could significantly reduce deaths in the region.

A structured autopsy-based audit of 370 firearm fatalities: Contribution to inform policy decisions and the probability of the injured arriving alive at a hospital and receiving definitive care. ACCIDENT; ANALYSIS AND PREVENTION 2013; 50:667-677.

Abstract
UNLABELLED The objectives of this autopsy-based audit of firearm-related fatalities were to acquire data to inform policy decisions and to assess the probability of the injured arriving alive at a hospital and receiving definitive care. EVALUATED VARIABLES Demographics; co-morbidities; location and intention of the injury; toxicology; types of firearms; Abbreviated Injury Scale; Injury Severity Score (ISS); transfer means and time; and location of death. RESULTS Of a total of 370 fatalities, 85.7% were male. The median age was 38 (9-95) years. Suicides (47%) and assaults (45.1%) were the most common underlying intentions. The most seriously injured regions were the head (44.5%), thorax (25.7%), abdomen (10.7%), and spine (5.7%). Of the 370 total subjects, 4.9% had an ISS<16 and 59.5% had an ISS≤74; both groups were classified as potentially preventable deaths. The majority (84%) died at the scene, and only 9.8% left the emergency department alive for further treatment. Multivariate analyses documented that postmortem ISS is an independent factor that predicts the probability of the injured reaching a hospital alive and receiving definitive care. Individuals injured in greater Athens and those most seriously injured in the face, abdomen or spine had significantly greater chances of reaching a hospital alive and receiving definitive care, whereas those injured by a shotgun and the positive toxicology group were significantly less likely to. In conclusion, this study provides data to inform policy decisions, calls for a surveillance network and establishes a baseline for estimating the probability regarding the location of firearm-related deaths.

Abstract
Abdominal vascular lesions are amongst the most lethal lesions suffered by patients with multiple injuries, as well as being among the most difficult and challenging for the surgeon. They are rarely isolated, they are usually found with associated multiple injuries, which increases its seriousness and the time required to repair them and may lead to a significant morbidity and mortality. The correct management involves an early diagnosis and surgical approach.

Abstract
BACKGROUND Time to definitive care is a major determinant of trauma patient outcomes yet little is empirically known about prehospital times at the national level. We sought to determine national averages for prehospital times based on a systematic review of published literature. METHODS We performed a systematic literature search for all articles reporting prehospital times for trauma patients transported by helicopter and ground ambulance over a 30-year period. Forty-nine articles were included in a final meta-analysis. Activation time, response time, on-scene time, and transport time were abstracted from these articles. Prehospital times were also divided into urban, suburban, rural, and air transports. Statistical tests were computed using weighted arithmetic means and standard deviations. RESULTS The data were drawn from 20 states in all four U.S. Census Regions and represent the prehospital experience of 155,179 patients. Average duration in minutes for urban, suburban, and rural ground ambulances for the total prehospital interval were 30.96, 30.97, and 43.17; for the response interval were 5.25, 5.21, and 7.72; for the on-scene interval were 13.40, 13.39, and 14.59; and for the transport interval were 10.77, 10.86, and 17.28. Average helicopter ambulance times were response 23.25, on-scene 20.43, and transport 29.80 minutes. CONCLUSIONS Despite the emphasis on time in the prehospital and trauma literature there has been no national effort to empirically define average prehospital time intervals for trauma patients. We provide points of reference for prehospital intervals so that policymakers can compare individual emergency medical systems to national norms.

Use of scene vital signs improves TRISS predicted survival in intubated trauma patients. J Surg Res 2008; 154:105-11. [PMID: 18805552 DOI: 10.1016/j.jss.2008.04.010] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2008] [Revised: 02/28/2008] [Accepted: 04/07/2008] [Indexed: 11/22/2022]
Abstract
INTRODUCTION The Trauma Related Injury Severity Score (TRISS) has been previously validated to predict outcomes in nonintubated, nonparalyzed trauma patients. The purpose of this study was to assess the impact of scene vital signs on predicting survival in intubated trauma patients. METHODS Our Trauma Registry of the American College of Surgeons was reviewed for all trauma patients admitted between 10/01/04 and 09/30/06, arriving by aeromedical transport. TRISS was evaluated for each patient based on their (1) scene vital signs and (2) arrival vital signs. Additionally, the "TRISS-like" score was calculated for each patient. Expected mortality for each score was measured against observed mortality. RESULTS Four thousand four hundred ninety-nine Trauma Registry of the American College of Surgeons patients were admitted during the study period; 695 (15%) were transported by air; 163 patients (23%) arrived intubated; 480 arrived nonintubated. Observed survival in the intubated group was 76%. Observed survival in the nonintubated group was 100%. TRISS using scene vital signs more closely predicted mortality among intubated patients than the other scoring systems (69% versus 39% using TRISS-arrival versus 80% using TRISS-like). Scene vital signs with TRISS also resulted in fewer "unexpected" outcomes (survivors and deaths). CONCLUSIONS Traditionally, patients arriving at trauma centers intubated are either excluded from the trauma registry or have their physiological score "modified" to account for pharmacologically altered respiratory rate and Glasgow Coma Scale. In intubated patients, TRISS using scene vital signs more reliably predicts survival and does so with far fewer "unexpected" outcomes than with other available scoring systems.

Emergency department thoracotomy: still useful after abdominal exsanguination? ACTA ACUST UNITED AC 2008; 64:1-7; discussion 7-8.

Abstract
BACKGROUND Although literature regarding emergency department thoracotomy (EDT) outcome after abdominal exsanguination is limited, numerous reports have documented poor EDT survival in patients with anatomic injuries other than cardiac wounds. As a result, many trauma surgeons consider prelaparotomy EDT futile for patients dying from intra-abdominal hemorrhage. Our primary study objective was to prove that prelaparotomy EDT is beneficial to patients with exsanguinating abdominal hemorrhage. METHODS A retrospective review of 237 consecutive EDTs for penetrating injury (2000-2006) revealed 50 patients who underwent EDT for abdominal exsanguination. Age, gender, injury mechanism and location, field and emergency department (ED) signs of life, prehospital time, initial ED cardiac rhythm, vital signs, Glasgow Coma Score, blood transfusion requirements, predicted mortality, primary abdominal injuries, and the need for temporary abdominal closure were analyzed. The primary study endpoint was neurologically intact hospital survival. RESULTS The 50 patients who underwent prelaparotomy EDT for abdominal exsanguination were largely young (mean, 27.3 +/- 8.2 years) males (94%) suffering firearm injuries (98%). Patients presented with field (84%) and ED signs of life (78%) after a mean prehospital time of 21.2 +/- 9.8 minutes. Initial ED cardiac rhythms were variable and Glasgow Coma Score was depressed (mean, 4.2 +/- 3.2). Eight (16%) patients survived hospitalization, neurologically intact. Of these eight, all were in hemorrhagic shock because of major abdominal vascular (75%) or severe liver injuries (25%) and all required massive blood transfusion (mean, 28.6 +/- 17.3 units) and extended intensive care unit length of stay (mean, 36.3 +/- 25.7 days). CONCLUSIONS Despite critical injuries, 16% survived hospitalization, neurologically intact, after EDT for abdominal exsanguination. Our results suggest that prelaparotomy EDT provides survival benefit to penetrating trauma victims dying from intra-abdominal hemorrhage.

Abstract
INTRODUCTION Complex liver injuries carry high morbidity and mortality ranging between 40 and 80%. OBJECTIVES To describe the characteristics of patients with liver trauma in the intensive care unit of our hospital, and the causes, severity scales, diagnoses, and treatments of these injuries, as well as length of hospital stay, morbidity and mortality. PATIENTS AND METHOD We retrospectively reviewed the patients with liver trauma admitted to our intensive care unit (ICU) from January 2000 to December 2005. There were two groups of patients: those who underwent surgery and those who received conservative treatment. RESULTS Univariate analysis revealed statistically significant differences between the two groups in the Acute Physiology and Chronic Health Evaluation II (APACHE II) score on admission to the ICU, the Injury Severity Score (ISS), and the percentage of severelesions according to the Liver Injury Scale (LIS), as well as in the coexistence of lesions in the large intestine. CONCLUSIONS From the statistical point of view, the two main variables guiding the therapeutic approach were hemodynamic instability and the need for transfusion. The indication for surgery showed a clear, although non-significant, association with mortality. Lastly, there was an association between the surgical option of packing and mortality.

Abstract
OBJETIVO: O trauma é um problema de saúde pública de enormes proporções. Constitui-se na principal causa de óbitos na população jovem. O Major Trauma Outcome Study (MTOS) é um estudo descritivo e retrospectivo da gravidade das lesões e evolução dos pacientes, considerado como o maior arquivo contemporâneo de informações descritivas de traumatizados. O objetivo do presente estudo é comparar o cálculo retrospectivo do New Injury Severity Score (NISS) com o Injury Severity Score (ISS) já calculado prospectivamente, utilizando o Trauma and Injury Severity Score (TRISS) e uma simples modificação deste índice, denominado de NTRISS (New Trauma and Injury Severity Score), e também comparar esta população submetida à laparotomia com os pacientes do MTOS. MÉTODO: Foram estudados 1.380 pacientes adultos traumatizados e submetidos à laparotomia na Disciplina de Cirurgia do Trauma da Unicamp, em Campinas, durante um período de oito anos. Os dados avaliados foram: demográficos, causa do trauma (fechado ou penetrante, ferimento por projétil de arma de fogo ou arma branca), estado fisiológico na admissão (RTS), diagnóstico anatômico de lesões (ATI, ISS e NISS), probabilidade de sobrevida utilizando o TRISS e o NTRISS, e a evolução do paciente (sobrevivência ou óbito). Foram utilizadas as estatísticas Z e W, inicialmente descritas por Flora, a fim de comparar a predição de óbitos ou sobreviventes com o estudo controle (MTOS). RESULTADOS: A maioria dos pacientes (88,3%) era do sexo masculino e jovem (média de idade de 30,4 anos). O ferimento por projétil de arma de fogo foi o mecanismo de trauma mais freqüente, com 641 casos (46,4%). Quatrocentos e trinta pacientes (31,2%) sofreram trauma fechado. As médias do ATI, ISS e NISS foram, respectivamente, de 12,3, 17,6 e 22,1. A taxa global de mortalidade foi de 16,8% e os pacientes com trauma contuso tiveram a maior mortalidade (29,3%). O NISS identificou melhor os sobreviventes e óbitos se comparado ao ISS, obtendo-se uma maior especificidade com o NTRISS. Foi observado um número significativamente menor de sobreviventes do que o esperado pelo estudo basal, com Z -16,24 com o TRISS e Z -9,40 se aplicado o NTRISS. Variações no valor da estatística W para cada paciente mostraram uma diferença no número de óbitos equivalente a 7,89 mais casos de óbito do que o esperado pelo MTOS, por 100 pacientes tratados, ao se empregar o TRISS, enquanto que estes valores foram reduzidos para 5,14 utilizando-se o NTRISS. CONCLUSÕES: Os métodos utilizados para cálculo da probabilidade de sobrevivência apresentaram limitações, particularmente nesta população com predomínio dos traumas penetrantes. O NISS, com o seu derivado NTRISS, foi o escore que obteve uma melhor predição de sobrevivência se comparado com o ISS. Os resultados obtidos com o TRISS e NTRISS foram estatisticamente piores do que os do MTOS, porém este processo de monitorização destes pacientes traumatizados tem sido importante para assegurar uma condição continuada de controle de qualidade.

Abstract
BACKGROUND Damage control surgery (DCS) and treatment of abdominal compartment syndrome have had major impacts on care of the severely injured. The objective of this study was to see whether advances in critical care, DCS, and recognition of abdominal compartment syndrome have improved survival from penetrating abdominal injury (PAI). METHODS The care of 250 consecutive patients requiring laparotomy for PAI (1997-2000) was reviewed retrospectively. Organ injury patterns, survival, and use of DCS and its impact on outcome were compared with a similar experience reported in 1988. RESULTS Two hundred fifty patients had a positive laparotomy for PAI. Twenty-seven (10.8%) required abdominal packing and 45 (17.9%) did not have fascial closure. Seven (2.8%) required emergency department thoracotomy and 21 (8.4%) required operating room thoracotomy. Two hundred seventeen (86.8%) survived overall. Small bowel (47.2%), colon (36.4%), and liver (34.4%) were most often injured. Mortality was associated with the number of organs injured (odds ratio, 1.98; 95% confidence interval, 1.65-2.37; p < 0.001). Vascular injury was a risk factor for mortality (p < 0.001), as was need for DCS (p < 0.001), emergency department thoracotomy (p < 0.001), and operating room thoracotomy (p < 0.001). Seventy-nine percent of deaths occurred within 24 hours from refractory hemorrhagic shock. DCS was used in 17.9% (n = 45) versus 7.0% (n = 21) in 1988, with a higher survival rate (73.3% vs. 23.8%, p < 0.001). DCS was associated with significant morbidity including sepsis (42.4%, p < 0.001), intra-abdominal abscess (18.2%, p = 0.009), and gastrointestinal fistula (18.2%, p < 0.001). CONCLUSION Penetrating abdominal organ injury patterns and survival from PAI have remained similar over the past decade. Death from refractory hemorrhagic shock in the first 24 hours remains the most common cause of mortality. DCS and the open abdomen are being used more frequently with improved survival but result in significant morbidity.

Abstract
BACKGROUND Performance improvement is an essential component of the trauma center. TRISS methodology has been applied as a national standard against which trauma centers can compare their outcomes. Earlier reviews of TRISS unexpected survivors sustained the classification of unexpected survivor in the vast majority of cases. Our hypothesis was that the level of care that is currently expected has made the TRISS unexpected survivors a statistical phenomenon only. METHODS Two hundred seventy TRISS unexpected survivors at a Level I trauma center from 1991 to 1995 were reviewed. Each case was reviewed as a blinded abstract by six reviewers (three of whom are directors at other facilities) and classified as clinically unexpected survivor (confirmed TRISS classification) or clinically expected survivor (did not sustain TRISS classification as unexpected survivor). Data are expressed as mean +/- SD. Statistical significance was achieved at p < 0.05. RESULTS Among the 270 patients categorized by TRISS as unexpected survivors, only 10.7% were corroborated as clinically unexpected survivors by this peer review process and 89.3% were reclassified as clinically expected survivors. Confirmed clinically unexpected survivors were more likely to go directly from the emergency department to the operating room (82 vs. 46%; p < 0.05). Age (32 +/- 12 years vs. 40 +/- 19 years; p < 0.05), Injury Severity Score (46 +/- 20 vs. 32 +/- 14; p < 0.05), Revised Trauma Score (2.46 +/- 1.89 vs. 3.11 +/- 1.21; p < 0.05), probability of survival (0.13 +/- 0.13 vs. 0.24 +/- 0.15; p < 0.05), systolic blood pressure in the emergency department (60 +/- 51 mm Hg vs. 109 +/- 33 mm Hg; p < 0.05), hospital length of stay (39.6 +/- 30.3 days vs. 24.0 +/- 23.0 days; p < 0.05), and intensive care unit length of stay (19.5 +/- 20.6 days vs. 9.6 +/- 10.1 days; p < 0.05) were significantly different comparing confirmed versus unsustained classification as unexpected survivors. CONCLUSION Only 10.7% of survivors classified as unexpected by TRISS were corroborated as unexpected by a blinded, peer-review process. TRISS needs to be updated for meaningful interpretation; modifications need to be made and coefficients need to be revised.

Abstract
OBJECTIVE To evaluate the effect of early optimization in the survival of severely injured patients. SUMMARY BACKGROUND DATA It is unclear whether supranormal ("optimal") hemodynamic values should serve as endpoints of resuscitation or simply as markers of the physiologic reserve of critically injured patients. The failure of optimization to produce improved survival in some randomized controlled trials may be associated with delays in starting the attempt to reach optimal goals. There are limited controlled data on trauma patients. METHODS Seventy-five consecutive severely injured patients with shock resulting from bleeding and without major intracranial or spinal cord trauma were randomized to resuscitation, starting immediately after admission, to either normal values of systolic blood pressure, urine output, base deficit, hemoglobin, and cardiac index (control group, 35 patients) or optimal values (cardiac index >4.5 L/min/m2, ratio of transcutaneous oxygen tension to fractional inspired oxygen >200, oxygen delivery index >600 mL/min/m2, and oxygen consumption index >170 mL/min/m2; optimal group, 40 patients). Initial cardiac output monitoring was done noninvasively by bioimpedance and, subsequently, invasively by thermodilution. Crystalloids, colloids, blood, inotropes, and vasopressors were used by predetermined algorithms. RESULTS Optimal values were reached intentionally by 70% of the optimal patients and spontaneously by 40% of the control patients. There was no difference in rates of death (15% optimal vs. 11% control), organ failure, sepsis, or the length of intensive care unit or hospital stay between the two groups. Patients from both groups who achieved optimal values had better outcomes than patients who did not. The death rate was 0% among patients who achieved optimal values compared with 30% among patients who did not. Age younger than 40 years was the only independent predictive factor of the ability to reach optimal values. CONCLUSIONS Severely injured patients who can achieve optimal hemodynamic values are more likely to survive than those who cannot, regardless of the resuscitation technique. In this study, attempts at early optimization did not improve the outcome of the examined subgroup of severely injured patients.

Abstract
BACKGROUND Injuries caused by firearms account for only a small percentage of trauma admissions and deaths in Australia but are frequently the subject of media and public attention. The present study examines the epidemiology and management of firearm injuries presenting to St Vincent's Hospital, which is located at the edge of the central business district of Sydney. METHODS The medical records of all patients presenting to St Vincent's with a gunshot wound (GSW) from January 1988 to December 1998 were analysed. Additional details were acquired from New South Wales State Coroner's Court reports and media archives, especially major newspapers. RESULTS Seventy-four patients presented to St Vincent's Hospital with 103 GSW. The age (mean +/- SD) was 31+/-11 years. Sixty-seven patients (91%) were male. Alcohol was identified as a factor in 24 cases (32%) while other drugs were indicated in four cases (5%). Ten patients (14%) had intentionally self-inflicted wounds, seven (9%) had accidental wounds and 57 (77%) had wounds that were caused by crime-related violence. Sixty patients (81%) underwent operation for their injury. Thirty complications were seen in 18 patients (24%). Eleven patients (15%) died. The length of hospital stay (mean +/- SEM) was 18+/-9 days. CONCLUSIONS The incidence of trauma due to firearms has not increased at St Vincent's hospital in the period 1988-98. Most GSW were inflicted in the setting of criminal violence, with a high proportion due to handguns. Patients were mostly young men, and alcohol or other drugs were frequently involved. Outcomes are comparable to other centres managing large volumes of penetrating trauma.
