Predictors of Mortality Among Pediatric Burn Patients in East Africa:

The effect of interhospital transfer on pediatric burn injury mortality in a resource-limited setting

INTRODUCTION

The World Health Organization's burn mortality estimate is 180,000 annually. Ninety-five percent of all mortality caused by fire-related burns worldwide occurs in low- and middle-income countries (LMICs). Prior studies have shown that transfer status (direct transfer from an injury scene to a trauma center vs. indirect transfer from another health facility) affects patient outcomes. We evaluated the effect of interhospital transfer on burn mortality.

METHODS

We analyzed a burn database of pediatric patients admitted to the Kamuzu Central Hospital (KCH) burn unit in Lilongwe, Malawi. We performed a bivariate analysis based on their transfer status and mortality and a logistic regression analysis to determine the effect of transfer status on mortality after burn injury.

RESULTS

A total of 2301 patients were analyzed, with 1095 (47.6%) being in the transfer cohort from referring hospitals. The median age was 3 years (IQR 1-4). The transfer cohort had more patients presenting to the hospital more than 48 h after injury. Upon multivariate logistic regression, controlling for pertinent variables, including time to presentation, burn-injured patients in the transfer cohort had increased odds of mortality (OR 2.26, 95% CI 1.22-4.19, and p = 0.01) compared to patients who were not transferred. The predictive probabilities of burn mortality by TBSA showed significant differences in mortality based on transfer status at TBSA between 20% and 80%.

CONCLUSION

Ensuring district hospitals and other primary health care centers in resource-limited settings are sufficiently equipped to provide initial burn resuscitation and care may decrease mortality rates associated with transferred patients.

Survival Status and Predictors of Mortality Among Pediatrics Burn Victims Admitted to Burn Centers of Addis Ababa Public Hospitals, Ethiopia: A Retrospective Cohort Study

Background. Burn is a major public health problem in pediatric populations worldwide. This study aimed to determine the survival status and predictors of mortality among pediatric burn victims admitted to burn centers in Ethiopia. Methods. A retrospective cohort study was conducted on the patient charts of 412 pediatric patients with burn injuries at burn centers in Addis Ababa from the 1st of January 2016 to the 30th of December 2019. Data was entered into the Epi-Data manager. Then, the data was exported to STATA V-14 for cleaning and analysis. For the analysis, the proportional hazard model was used. After the model fitness test, variables with a P-value of <.25 in the bivariate analysis were fitted to the multivariate analysis. Finally, statistical significance was decided at a P-value of <.05, and the hazard ratio was used to determine the strength of the association. Result. The study reported an overall incidence rate of 2.4 per 1000 child days. Additionally, it revealed that the median hospital length of stay was 25.00 days (95% CI: 21.57, 28.45). During the follow-up period, 8.25% of deaths occurred among pediatric patients with burn injuries. Specifically, having a full-thickness burn (adjusted hazard ratio [AHR] 2.51, 95% CI: 1.12, 5.62) and neck burn (AHR 2.82, 95% CI: 1.04, 7.68) were identified as significant predictors contributing to increased mortality among burn-injured pediatric individuals. Conclusion. The study highlighted significant mortality rates among pediatric patients suffering from burn injuries. Based on the findings a full-thickness burn injury and burns in the neck area are independent predictors of mortality in pediatric burn patients. Based on the identified predictors of mortality in pediatric burn patients, clinicians should prioritize early recognition, prompt intervention, multidisciplinary management, vigilant monitoring, and preventive strategies to optimize outcomes and reduce mortality rates in this vulnerable population.

Food Security as a Predictor of Global Pediatric Postburn Mortality

Food security (FS) is defined as access to sufficient and nutritious food. Children, especially those in low- and middle- income countries (LMICs), are disproportionately affected by low FS. We hypothesized high FS would be predictive of decreased pediatric postburn mortality in LMICs. Publicly-available, deidentified datasets were obtained from the World Health Organization's Global Burn Registry (GBR) and Economist Intelligence Unit's Global FS Index (GFSI). The GFSI calculates FS scores annually from intergovernmental organization data reviewed by a panel of experts. FS scores are reported on a 0 to 100 scale with 100 indicating the highest FS. Patients aged 0 to 19 yr were included; after linking GBR and GFSI datasets, countries with <100 burn patients were excluded. Data were analyzed with descriptive statistics and bivariate analyses. Multiple logistic regression controlling for confounders was used to quantify associations between mortality and FS score. Significance was set at P < 0.05. From 2016 to 2020, there were 2,246 cases including 259 deaths (11.5%) over nine countries. Those who died had a higher median age (7 [IQR 2, 15] vs 3 [2, 6] years, P < 0.001), higher proportion of females (48.6% vs 42.0%, P =0.048), and lower median FS score (55.7 [IQR 45.3, 58.2] vs 59.8 [IQR 46.7, 65.7], P < 0.001). Increasing FS score was associated with decreased odds of postburn mortality [multivariable odds ratio 0.78 (95% confidence interval 0.73 to 0.83), P < 0.001]. With the association between FS and mortality, international efforts to increase FS in LMICs may help improve pediatric burn patient survival.

Outcome of burn injury and associated factor among patient visited at Addis Ababa burn, emergency and trauma hospital: a two years hospital-based cross-sectional study

BACKGROUND

Burn is one of the critical health problems worldwide. Developing countries with sub-Saharan and Asian populations are affected more. Its mortality and non-fatal complications depend on several factors including age, sex, residency, cause, the extent of the burn, and time and level of care given.

OBJECTIVE

The purpose of this study was to assess the outcome of burn injury and its associated factor among patients who visited Addis Ababa burn emergency and trauma hospital.

METHODS

The institutional-based, retrospective cross-sectional study design was conducted from April 1, 2019, to March 30, 2021. After checking the data for its consistency the data were entered and analyzed by using SPSS version 25. A total of 241 patients who had visited Addis Ababa burn, emergency and trauma Hospitals after sustained burn injury were recruited through convenience sampling method for final analysis. Model goodness-of-fit was checked by Hosmer and Lemeshow test (0.272). After checking multi-collinearity both the bi-variable and multivariable logistic regression model was fitted and variables having a p-value less than or equal to 0.05 at 95% CI in the multivariable analysis were considered statistically significant.

RESULT

Adults (age 15 to 60 years) are the most affected groups accounting for 55.2% followed by pediatric age groups (age <15 years) (43.6%) and the elderly (age > 60 years) (1.2%). Scald burn was the major cause accounting for 39 % followed by Flame burn (33.6%), Electrical burn (26.6%), and chemical burn (0.8%). The mean TBSA% was 15.49%, ranging from1% to 64%. Adult males are more affected by electrical burns while adult females and the elderly encounter flame burn. 78.4% of patients were discharged without complications, 14.9% were discharged with complications and 6.6% died. The commonest long-term complication is the amputation of the extremity (19, 7.9%). Age greater than 60 years and TBSA% greater than 30% is a strong predictors of mortality with odds of 2.2 at 95% CI of [1.32, 3.69] and 8.7 at 95% CI of [1.33, 57.32] respectively.

CONCLUSION AND RECOMMENDATION

The mortality rate show decrement from previous studies. Overall scald burn is common in all age groups but electrical burns and flame burns affected more adult and elderly age groups. Extremities were by far, the commonest affected body parts. The extent of burn injury and the age of the patient independently predict mortality. Early intervention will reduce mortality and complications.

Characteristics and predictors of mortality in-hospital mortality following burn injury in infants in a resource-limited setting

PURPOSE

Burn outcome data in infants is lacking from sub-Saharan Africa. We, therefore, sought to assess the characteristics and predictors of in-hospital burn mortality in a resource-limited setting.

METHODS

We performed a retrospective study of the prospectively collected Burn Injury Surveillance database from June 2011 to December 2019. We performed bivariate analysis and Poisson regression to assess risk factors for mortality in our infant burn population.

RESULTS

115 (7.3%) infants met inclusion criteria. The median age of 8 months (IQR: 6-10) and primarily male (n = 67, 58.8%). Most burns were from scald (n = 62, 53.9%). Infant burn mortality was 12.2%. Poisson multivariable regression to determine burn mortality risk in infants showed that increased %TBSA burns (RR 1.04, 95% CI 1.01-1.07) and flame burns (RR 3.08, 95%CI 1.16-8.16) had a higher risk of mortality. Having surgery reduced the relative risk of death for infants with burns.

CONCLUSION

We show that factors that increase infant burn mortality risk include percent total body surface area burn, flame burn mechanism, and lack of operative intervention. Increasing burn operative capability, particularly for infants and other children, is imperative.

Magnitude of mortality and its associated factors among Burn victim children admitted to South Gondar zone government hospitals, Ethiopia, from 2015 to 2019

BACKGROUND

Burn is one of the leading causes of preventable death and disability every year in low and middle-income countries, which mainly affects those aged less than 15 years. Death from burn injuries carries the most significant losses, which often have grave consequences for the countries. Even though data from different settings are necessary to tackle it, pieces of evidence in this area are limited. Thus, this study was aimed to answer the question, what is the Magnitude of Mortality? And what are the factors associated with mortality among burn victim children admitted to South Gondar Zone Government Hospitals, Ethiopia, from 2015 to 2019?

METHODS

Institutional-based cross-sectional study design was used to study 348 hospitalized burn victim pediatrics', from 2015 to 2019. A simple random sampling method was used. Data were exported from Epidata to SPSS version 23 for analysis. Significant of the variables were declared when a p-value is < 0.05.

RESULT

The mortality rate of burn victim children in this study was 8.5% (95% CI = 5.5-11.4). Medical insurance none users burn victim children were more likely (AOR 3.700; 95% CI =1.2-11.5) to die as compared with medical insurance users, burn victim children with malnutrition were more risk (AOR 3.9; 95% CI = 1.3-12.2) of mortality as compared with well-nourished child. Moreover, electrical (AOR 7.7; 95% CI = 1.8-32.5.2) and flame burn (AOR 3.3; 95% CI = 1.2-9.0), total body surface area greater than 20% of burn were more likely (AOR 4.6; 95% CI 1.8-11.8) to die compared to less than 20% burn area and burn victim children admitted with poor clinical condition at admission were four times (AOR 4.1, 95% CI = 1.3-12.0) of mortality compared to a good clinical condition.

CONCLUSION

The mortality among burn victim children was higher than most of the studies conducted all over the world. Medical insurance none users, being malnourished, burned by electrical and flame burn, having total body surface area burnt greater than 20%, and having poor clinical condition at addition were significantly associated with mortality of burn victim pediatrics. Therefore, timely identification and monitoring of burn injury should be necessary to prevent mortality of burn victim pediatrics.

Factors associated with outcomes after burn care: A retrospective study in Eastern Democratic Republic of Congo

OBJECTIVE

In low income countries, incidence of burns is high and severe burns are frequently managed at peripheral facilities. Outcome after burn care is poorly studied although it might help identify risk-group and improve treatment strategies. This study aimed to study factors associated with in-hospital outcomes in a burn cohort in the Democratic Republic of Congo.

METHODS

In this retrospective study we included burn patients admitted to the surgical department at the Hôpital Provincial Général de Référence de Bukavu between January 2013 and December 2018. Differences between groups were tested using χ2 test or Fisher's exact tests or Wilcoxon rank sum test, as appropriate. Multivariate logistic regression was used to analyze the effect of patients and of burn characteristics on in-hospital mortality, prolongated length of stay (=LOS≥25days) and occurrence of complications.

RESULTS

The study population consisted of 100 patients, mainly young male with rural origin, moderate sized but deep burns. Of them, 46 developed complications, 12 died. Median LOS was 25 days (IQR: 15-42). In-hospital death was independently associated with Total Burn Surface Area percentage "TBSA%" (OR=3.96; 95% CI=1.67-9.40) and Full thickness Burns "FTB" (10.68; 1.34-84.74); prolongated LOS with FTB (3.35; 1.07-10.49), and complication with rural origin (5.84; 1.51-22.53), TBSA% (3.96; 1.67-9.40), FTB (4.08; 1.19-14.00) and burns on multiple sites (4.38; 1.38-13.86).

CONCLUSION

In-hospital death was associated with TBSA% and FTB, prolongated LOS with FTB, and complication with burns characteristics and rural origin of the patients. Further studies are necessary to investigate the effect of provided burn care on outcomes.

The Association Between Burn Unit Census and Operative Intervention in a Resource-Limited Setting

INTRODUCTION

The relationship between hospital volume and outcomes remains unclear in the delivery of burn care in resource-limited settings, where demand often exceeds capacity. We sought to characterize the association between burn patient volume and the use of operative intervention at a tertiary burn unit in Malawi.

METHODS

This study examined patients admitted to Kamuzu Central Hospital located in Lilongwe, Malawi, over years 2011-2019. We described the association between the census at the time of admission and the use of operative intervention, as well as the time to operation. Patient census was defined as low (≤ 15 patients), medium (16-29 patients), and high (≥ 30 patients).

RESULTS

A total of 2484 patients were included. The mean daily burn unit census was 22.5 patients (SD 6.6) and varied significantly by season. For the medium and high census, the adjusted risk ratio of undergoing surgery was 0.79 (95% CI 0.64, 0.97) and 0.65 (95% CI 0.49, 0.85), respectively, adjusted for flame burn, age, %TBSA, and delayed presentation. At a low admission census, the adjusted mean time to operation was 17.2 days (95% CI 14.4, 20.1) compared to 28.3 days (95% CI 25.4, 31.2) at a high census.

CONCLUSIONS

In a resource-limited setting, an increasing mean daily census significantly reduced the use of operative intervention and increased time to operation, potentially increasing burn-associated morbidity. In order to improve the quality of burn care in similar environments, improved resource allocation during busier seasons and targeted burn prevention efforts are imperative.

Presentation of Pediatric Unintentional Injuries at Rural Hospitals in Rwanda: A Retrospective Study

Background:

Injuries are a leading cause of mortality among children globally, with children in low- and middle-income countries more likely to die if injured compared to children in high-income countries. Timely and high-quality care are essential to reduce injury-related morbidity and mortality.

Objectives:

This study describes patterns, management, and outcomes of children 0–15 years presenting with unintentional injuries at three district hospitals in rural Rwanda between January 1 and December 31, 2017.

Methods:

Using a retrospective cross-sectional study design, we assessed the demographic and clinical characteristics, care provided, and outcomes of the children using data extracted from patient medical charts. We describe the patient population using frequencies and proportions as well as median and interquartile ranges.

Findings:

Of the 449 injured children who sought care at the three rural district hospitals, 66.2% (n = 297) were boys. The main causes of injury were falls (n = 261, 58.1%), burns (n = 101, 22.5%), and road traffic injuries (n = 67, 14.9%). Burns were the most common injury among children aged 0–5 years while falls were the leading injury type among the 5–15 years age group. Vital signs were inconsistently completed ranging between 23.8–89.1% of vital sign items. Of the injured children, 37.0% (n = 166) received surgery at the district hospital, general practitioners performed 80.9% (n = 114) of surgeries, 87.4% (n = 145) of operated patients received no anesthesia, and 69.3% (n = 311) were admitted to the district hospital, while 2.7% (n = 12) were transferred to tertiary facilities for higher-level care.

Conclusions:

The presentation of child injuries—namely falls, burns, and road traffic accidents—is similar to what has been reported in other sub-Saharan African countries. However, more needs to be done to improve the completion and documentation of vital signs and increase availability of surgical specialists. Finally, targeted strategies to prevent burns and motorcycle-related injuries are recommended prevention interventions for this rural population.

Access to Operative Intervention Reduces Mortality in Adult Burn Patients in a Resource-Limited Setting in Sub-Saharan Africa

INTRODUCTION

Early excision and grafting remains the standard of care after burn injury. However, in a resource-limited setting, operative capacity often limits patient access to surgical intervention. This study sought to describe access to excision and grafting for adult burn patients in a sub-Saharan African burn unit and its relationship with burn-associated mortality.

METHODS

We analyzed patients recorded in the Kamuzu Central Hospital Burn Registry in Lilongwe, Malawi from 2011-2019. We examined patient characteristics, interventions, and outcomes for adults aged ≥16 years. Modified Poisson regression modeling was used to identify risk factors for mortality.

RESULTS

Five hundred and seventy-three patients were included. Median age was 30 years (IQR 23-40) with a male preponderance (63%). Median percent total body surface area burned (%TBSA) was 15% (IQR 8-26) and 68% of burns were caused by flame. 27% (n = 154) had burn excision with skin grafting, with a median time to operation of 18 days (IQR 9-38). When adjusted for age, %TBSA, and time to presentation, operative intervention conferred a survival benefit for patients with flame burns with a RR 0.16 (95% CI 0.06, 0.42).

CONCLUSIONS

In a resource-limiting setting, access to the operating room is inadequate, and burn patients are not prioritized. While many scald burn patients may be managed with wound care alone, patients with flame burn require surgical intervention to improve clinical outcomes. Burn injury in this region continues to confer a high risk of mortality, and more investment in operative capacity is imperative.

Survival analysis and mortality predictors of hospitalized severe burn victims in a Malaysian burns intensive care unit

Background

Prognostic measures to determine burn mortality are essential in evaluating the severity of individual burn victims. This is an important process of triaging patients with high risk of mortality that may be nursed in the acute care setting. Malaysian burn research is lacking with only one publication identified which describes the epidemiology of burn victims. Therefore, the objective of this study was to go one step further and identify the predictors of burn mortality from a Malaysian burns intensive care unit (BICU) which may be used to triage patients at higher risk of death.

Methods

This is a retrospective cohort study of all admissions to Hospital Sultan Ismail’s BICU from January 2010 till October 2015. Admission criteria were in accordance with the American Burn Association guidelines, and risk factors of interest were recorded. Data was analyzed using simple logistic regression to determine significant predictors of mortality. Survival analysis with time to death event was performed using the Kaplan-Meier survival curve with log-rank test.

Results

Through the 6-year period, 393 patients were admitted with a male preponderance of 73.8%. The mean age and length of stay were 35.6 (±15.72) years and 15.3 (±18.91) days. There were 48 mortalities with an overall mortality rate of 12.2%. Significant risk factors identified on simple logistic regression were total body surface area (TBSA) > 20% (p < 0.001), inhalation injury (p < 0.001) and presence of early systemic inflammatory response syndrome (SIRS) (p < 0.001). Survival analysis using Kaplan-Meier survival curve showed similar results with TBSA > 20%, presence of SIRS, mechanical ventilation and inhalation injury which were associated with poorer survival (p < 0.001).

Conclusion

The predictors of mortality identified in a Malaysian BICU were TBSA > 20%, early SIRS, mechanical ventilation and inhalation injury which were associated with poorer survival outcome. The immunological response differs from individual patients and influenced by the severity of burn injury. Early SIRS on admission is an important predictor of death and may represent the severity of burn injury. Patients who required mechanical ventilation were associated with mortality and it is likely related to the severity of pulmonary insults sustained by individual patients. This data is important for outcome prognostication and mortality risk counselling in severely burned patients.

Pre-burn malnutrition increases operative mortality in burn patients who undergo early excision and grafting in a sub-Saharan African burn unit

INTRODUCTION

In the developed world, pre-existing malnutrition in the burn population influences operative outcomes. However, studies on pre-existing malnutrition and operative outcomes of burn patients in the developing world are lacking. We therefore sought to characterize the burn injury outcomes following operative intervention based on nutritional status.

METHODS

This is a retrospective review of operative patients admitted to our burn unit from July 2011 to May 2016. Age-adjusted Z scores were calculated for height, weight, weight for height, and mid-upper arm circumference (MUAC). Following bivariate analysis, we constructed a fully adjusted logistic regression model of significant predictors of post-operative mortality, both overall and for specific age categories.

RESULTS

Of the 1356 admitted patients, 393 received operative intervention (29%). Of those, 205 (52.2%) were male, and the median age was 6 years (3, 25), with 265 patients (67%) aged ≤16 years. The median TBSA was 15.4% (10%-25%) and open flames caused the majority of burns (64%), though in children under 5, scalds were the predominant cause of burn (52.2%). Overall mortality was 14.5% (57 patients) and ranged from 9.09% for patients aged 6-16, to 33.3% for adults ≥50years. Increased time from injury to operative intervention was protective (OR: 0.90, 95% CI: 0.83, 0.99). In post-operative patients with z-scores, increasing %TBSA burned (OR: 1.11, 95% CI: 1.05, 1.17) and increasing malnutrition (OR: 1.46, 95% CI: 1.03, 1.91) predicted death in the adjusted model.

CONCLUSION

Poor nutrition is an important risk factor for post-operative mortality in burned patients in resource-poor settings. Screening for malnutrition and designing effective interventions to optimize nutritional status may improve surgical outcomes in LMIC burn patients.

A prospective analysis of risk factors for pediatric burn mortality at a tertiary burn center in North India

BACKGROUND

None of the available mortality predicting models in pediatric burns precisely predicts outcomes in every population. Mortality rates as well as their risk factors vary with regions and among different centers within the regions. The aim of this study was to identify socio-demographic and clinical risk factors for mortality in pediatric burns in an effort to decrease the mortality in these patients.

METHODS

A prospective analytical study was conducted in patients up to the age of 18 years admitted for burn injuries in a tertiary care burn center in India from January to December 2014. Clinical and demographic data was collected through questionnaire-interview and patient follow-up during their stay in the hospital. Univariate and multivariate firth logistic regression was used to identify various risk factors for mortality in pediatric burns.

RESULTS

A total of 475 patients were admitted during the study period. Overall mortality was 31.3% (n = 149) in this study. Mean age of the patients who died was 8.68 years. Of the 149 deaths, 74 were males and 75 were females (male to female ratio = 0.98). Mean total body surface area (TBSA) involved of the patients who expired was 62%. Inhalational injury was seen in 15.5% (n = 74) of pediatric burn admissions. Mortality was significantly higher (74.3%) in patients with inhalation injury. Mortality was highest in patients with isolates of Acinetobacter + Klebsiella (58.3%), followed by Pseudomonas + Klebsiella (53.3%), Acinetobacter (31.5%), and Pseudomonas (26.3%) (p < 0.0005). Factors found to be significant on univariate firth analysis were older age, female gender, suicidal burns, higher TBSA, presence of inhalation injury, increased depth of burn, and positive microbial cultures. On multivariate analysis, higher TBSA was identified as an independent risk factor for mortality. The adjusted odds ratios for TBSA involvement was 21.706 (25.1-50%), 136.195 (50.1-75%), and 1019.436 (75.1-100%), respectively.

CONCLUSION

TBSA is the most important factor predicting mortality in pediatric burns. The higher the TBSA, the higher is the risk of mortality. Other significant risk factors for mortality are female gender, deeper burns, positive wound cultures, and inhalation injury. Risk of mortality was significantly lower in children who belonged to urban areas, nuclear family, who sustained burn injury in the last quarter of the year, and who stayed in the hospital for longer period.
