A plastic and reconstructive surgery landscape assessment of Malawi: a scoping review of Malawian literature

Background

Plastic and reconstructive surgery (PRS) remains highly relevant to the unmet need for surgery in Malawi. Better understanding the current PRS landscape and its barriers may help address some of these challenges. This scoping review aimed to describe: (1) the scope and focus of the PRS literature being produced in Malawi and (2) the challenges, deficits, and barriers to providing accessible, high-quality PRS in Malawi.

Methods

This scoping review was conducted on four databases (SCOPUS, PubMed, Web of Science, EMBASE) from inception through September 1, 2020 following the PRISMA-ScR guidelines.

Results

The database search retrieved 3852 articles, of which 31 were included that examined the burden of PRS-related conditions in Malawi. Of these 31 articles, 25 primarily discussed burn-related care. Burns injuries have a high mortality rate; between 27 and 75% in the studies. The literature revealed that there are only two burn units nationally with one PRS specialist in each unit, compounded by a lack of interest in PRS specialization by Malawian medical students. Congenital anomalies were the only other PRS-related condition examined and reported in the literature, accounting for 23% of all pediatric surgeries in tertiary facilities.

Conclusions

There is a need to increase the country's capacity to handle burn reconstruction and other PRS-related conditions to reduce overall morbidity and mortality. Additional publicly funded research at the district and community level is warranted to determine the true burden of PRS disease in Malawi to derive health system strengthening and workforce capacity building strategies.

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.

Türkiye Güneydoğu Anadolu bölgesinde pediatrik yanık vakalarının analizi:10 yıllık retrospektif çalışma

Background: Burns continue to be a serious global public health problem all over the world, especially in developing countries. Materials and Methods: The age, gender, cause of injury, and total body surface area (TBSA) of the burn, complications, and mortality rate of 1,038 patients who were hospitalized in our burn center between January 1, 2010, and January 1, 2020, were analyzed. Results: The burned surface area was greater in boys than in girls. The mean burned body surface area for all patients was 9.2 ± 6.35, and the mortality rate was 1.45%. Hot liquids, such as tea, hot milk, hot water, and oily food, were the causes of burns in 84.7% of the patients. Hot objects, hot melted nylon, hot tandoor and embers, and hot asphalt accounted for 7.7% of the burns. Moreover, flame burns, electrical burns and frostbite, and other burn causes accounted for 5.6%, 1.2 %, and 0.8% of burn injuries, respectively. Conclusions: In our region, pediatric burns occurred mostly in boys under the age of three and in children whose parents had low educational levels living in rural areas. We believe that the burn prevention program should be adjusted according to these results.

Age-dependent influence of premorbid underweight status on mortality in severe burn patients: An administrative database study

PURPOSE

To examine the associations between premorbid nutritional status and in-hospital mortality in severe burn patients according to age in Japan.

METHODS

We retrospectively extracted the data of 14,345 patients aged 18-84 years admitted for burns from April 1, 2014, to March 31, 2018, using the Japanese Diagnosis Procedure Combination database. The exclusion criteria were out-of-hospital cardiac arrest, death in the emergency room, readmission, and planned admission. We collected data on age, sex, height, weight, comorbidities, burn index, and mechanical ventilation use and performed age-stratified multilevel logistic regression analyses to estimate associations between premorbid body mass index (BMI) and in-hospital mortality.

RESULTS

We analyzed 2968 patients with a burn index ≥10, including 831 elderly aged 75-84 years. In patients aged 18-74 years, being underweight (BMI < 18.5) significantly decreased mortality (0.34 [0.15-0.77]; P = 0.010). In contrast, in patients aged 75-84 years, being underweight significantly increased mortality (2.11 [1.05-4.25]; P = 0.036). Being overweight (BMI >25) increased mortality in both age groups, but not significantly.

CONCLUSIONS

The results suggest that pre-morbidly underweight elderly patients aged 75-84 years with severe burns have high mortality risks. Further research is needed to identify optimal care strategies for this 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.

Clearance of Indocyanine Green in Severe Pediatric Burns

BACKGROUND

Clearance of indocyanine green dye (ICGc) reflects sinusoidal perfusion and hepatocyte cell membrane function. Thus, ICGc is a reflection of the functional reserve of intact hepatocytes. The purpose of this study was to identify predictors of ICGc in severely burned children during the acute hospitalization and at the time of discharge from the intensive care unit (ICU). A secondary aim was to determine the relationship between liver size and patient ICGc.

METHODS

Twenty-six children (0.8-17 years old) with 35% or greater total body surface area burned (%TBSA-B) were included. Assessment of ICGc (in milliliters per minute per meter squared) was done during the acute hospitalization (median: 6 days after admission, median: 14 days postburn) and at the time of discharge from the ICU (median: 19 days after admission, median: 27 days postburn). Age, TBSA-B, % third-degree burns, inhalation injury, preexisting chronic malnutrition, hematocrit, liver dysfunction, and time from burn injury were incorporated in multiple linear regressions as predictive variables of ICGc. Only variables with p < 0.05 were retained in the final models.

RESULTS

Time from injury and age were the strongest predictors of ICGc during the acute admission but not at the time of discharge from the ICU. Time from injury was negatively associated with ICGc, whereas age was positively associated. At the time of discharge from the ICU, ICGc was increased in proportion to the %TBSA-B, whereas inhalation injury and preexisting chronic malnutrition were associated with lower ICGc. There was no correlation between change-to-predicted liver length and ICGc.

CONCLUSIONS

The intrinsic ability of the liver to extract ICG from plasma was lower in younger burned patients during the acute admission and in those with preexisting chronic malnutrition and inhalation injury at the time of discharge from the ICU.

Epidemiologic shifts for burn injury in Ethiopia from 2001 to 2016: Implications for public health measures

BACKGROUND

The last generation has seen Ethiopia, a low income country with a population of 100 million people, undergo a marked increase in urbanization and development. The effects of these demographic changes on the epidemiology of burn risk and thermal injury in Ethiopia are unknown. This gap constitutes a major barrier to the creation of effective burn prevention programs.

METHODS

Yekatit 12 Hospital in Addis Ababa is the only burn unit in Ethiopia. In this cross sectional retrospective study, we identified and reviewed all admissions due to burn injury at that facility between 1/1/2016 and 12/31/2016. We then compared them to a previously published burn cohort treated at the same facility between 7/1/2001 and 9/31/2002. Chi square was used to compare proportions between the two samples. Continuous covariates are reported as descriptive data due to missing variance data in the 2001-02 publication.

RESULTS

There were a total of 121 subjects in the 2001-02 sample and 176 subjects in the 2016 sample. The 2016 sample was found to have a significantly larger proportion of males (57%) as compared to the 2001-02 sample (36%) (p=0.0003) and a significantly higher proportion of electrical injuries (27%) than the previous cohort (5%) (p<0.0001). No significant differences were seen in mortality rates between the 2016 and 2001-02 cohorts (8% vs 12%, respectively, p=0.29) or in the regions of origin (44% outside Addis Ababa vs 54%, p=0.09) For the 2016 sample, the highest surviving Baux score was 76 while the mean Baux score for survivors was 29.6±20.11.

CONCLUSION

As Ethiopia has become more industrialized over the last 15 years, the demographic pattern of burn injury has changed accordingly as electrical injuries have increased five-fold with males now constituting a majority of burn cases.

Characterizing Pediatric Non-Malarial Fever and Identifying the At-Risk Child in Rural Malawi

Objective. To characterize children with non–malarial fever at risk of nonrecovery or worsening in rural Malawi. Methods. This is a subgroup analysis of patients ≤14 years of age from a prospective cohort study in non–malarial fever subjects (temperature ≥37.5°C, or fever within 48 hours, and malaria negative) in southern Malawi cared for at a mobile clinic during the 2016 dry (August to September) or wet (November to December) season. Data collection included chart review and questionnaires; 14-day follow-up was conducted. We conducted univariate descriptive statistics on cohort characteristics, bivariate analyses to examine associations between characteristics and outcomes, and multivariate logistic regressions to explore factors associated with nonrecovery. Results. A total of 2893 patients were screened, 401 were enrolled, 286 of these were children, and 280 children completed follow-up. Eighty-seven percent reported symptom resolution, 12.9% reported no improvement, and there were no deaths or hospitalizations. No improvement was associated with dry season presentation (42.6% vs 75.0%, P < .0003), >2 days of symptoms (51.6% vs 72.2%, P = .03), and food insecurity (62.3% vs 86.1%, P = .007). Dry season subjects had a 4.35 times greater likelihood of nonimprovement (95% confidence interval [CI] = 1.96-11.11). Household food insecurity and being >2 hours from a permanent clinic were associated with no improvement (adjusted odds ratio [AOR] = 4.61, 95% CI = 1.81-14.29; and AOR = 2.38, 95% CI = 1.11-5.36, respectively). Conclusion. Outcomes were generally excellent in this rural, outpatient pediatric cohort, though risk factors for nonrecovery included food insecurity, access to a standing clinic, and seasonality. Ideally, this study will inform clinic- and policy-level changes aimed at ameliorating the modifiable risk factors in Malawi and throughout rural Africa.
