Burns among older persons: A narrative review

Understanding Epidemiological Trends in Geriatric Burn Injuries: A National Multicenter Analysis from NEISS 2004-2022

Burn injuries pose a significant source of patient morbidity/mortality and reconstructive challenges for burn surgeons, especially in vulnerable populations such as geriatric patients. Our study aims to provide new insights into burn epidemiology by analyzing the largest national, multicenter sample of geriatric patients to date. Using the National Electronic Injury and Surveillance System (NEISS) database (2004-2022), individuals with a "burn" diagnosis were extracted and divided into 2 comparison age groups of 18-64 and 65+. Variables including sex, race, affected body part, incident location, burn etiology, and clinical outcomes were assessed between the 2 groups using 2 proportion z-tests. About 60,581 adult patients who sustained burns were identified from the NEISS database with 6630 of those patients categorized as geriatric (65+). Geriatric patients had a significantly greater frequency of scald burns (36.9% vs 35.4%; P < .01), and third-degree/full-thickness burns (10.4% vs 5.5%, P < .01) relative to nongeriatric adult patients with most of these burns occurring at home (75.9% vs 67.4%; P < .01). The top 5 burn sites for geriatric patients were the hand, face, foot, lower arm, and lower leg and the top 5 burn injury sources were hot water, cookware, oven/ranges, home fires, and gasoline. Geriatric patients had over 2 times greater risk of hospital admission (odds ratio [OR]: 2.32, 95% CI: 2.17-2.49, P < .01) and over 5 times greater risk of emergency department mortality (OR: 6.22, 95% CI: 4.00-9.66, P < .01) after incurring burn injuries. These results highlight the need for stronger awareness of preventative measures for geriatric burn injuries.

Swallowing impairment in older persons following burn injury: Validation of incidence and predictive factors for dysphagia

BACKGROUND

Early retrospective data identify that dysphagia is common in older persons with burn injury, suggesting a rate of 47 %, and that it is associated with medical, burn, and nutritional outcomes.

AIMS

To prospectively (1) explore the incidence, (2) describe associations, and (3) evaluate risk factors for dysphagia in patients ≥ 75 years old hospitalised with burn injury.

METHODS

All patients > 75 years old admitted to Concord-Repatriation-General-Hospital with burn injury over 4 years (2019-2023) were assessed for dysphagia on presentation and were continually monitored throughout their admission. Burn injury, demographic, and nutritional data were prospectively captured and analysed for association with dysphagia.

RESULTS

Sixty-two patients (33 male) aged 75-95 years (median=83 years) were recruited. Dysphagia was identified in 50 %. Dysphagia was associated with burn size (p = 0.002), pre-existing cognitive impairment (p = 0.000), hospital length of stay (p = 0.001), in-hospital complications (p = 0.000), feeding dependence (p = 0.002), nutritional status (p = 0.013) and enteral feeding duration (p = 0.030). Cognitive impairment was the most sensitive predictor for dysphagia at 100 % (specificity=29 %, NPV=100 %, PPV=59 %). Development of secondary comorbidities was less sensitive at 52 % (NPV 65 %), but was associated with high specificity (90 %) and PPV (84 %).

CONCLUSIONS

One in every two patients ≥ 75 years admitted with burn injury will demonstrate dysphagia during their hospital admission. Those with pre-existing cognitive impairment are most at risk.

Global epidemiology of geriatric burns, capacities of care, and injury outcomes: Perspectives from the World Health Organization global burn registry

BACKGROUND

An increasing aging population alongside a potentially increasing injury risk emphasizes a critical need for evidence-based burn care regarding preventive and therapeutic strategies tailored to the unique needs of older adults. However, we note a critical gap in understanding geriatric burn trends on a global scale and the care capacity across settings. Thus, this study sought to ascertain the global trend of geriatric burns with a focus on patient demographics, injury characteristics, capacities of care, and injury outcomes.

METHODS

A retrospective design focusing on older adults aged ≥ 60 years with burns recorded in the World Health Organization Global Burn Registry as of 31st May 2023 was employed. Descriptive statistics were employed to analyze the data.

RESULTS

Of the 9277 records obtained from the Global Burn Registry, 849 participants (9.2%) were aged ≥ 60 years with the majority of these reported from the Eastern Mediterranean (EMRO) and Southeast Asia (SEARO) regions. More females than males were involved in burn injuries with the most common aetiological factor being flame. Most burns occurred in the home/ domestic setting with a seasonal variation (more injuries occurred in December and January). In terms of burn care capacity, the data suggest the availability of specialized services in most settings albeit the AFRO and SEARO regions still lacked the resources to offer specialized burn care. While most injured older adults were discharged home with no physical impairment (395, 46.5%), a substantial number died (250, 29.4%) during hospitalization, particularly in the African (AFRO) region and 111 (11.1%) left the facility against medical advice with the majority from the SEARO region (88).

CONCLUSION

Burn injuries in older adults remain a public health issue. On the preventive aspect, the results demonstrate a need to intensify safety in the home or domestic setting, and during festive seasons. Therapeutically, the findings underscore a need to consider the inclusion of more specialist geriatric and palliative care services in the burn management process. Additionally, we identified a need to strengthen burn care capacity in the AFRO and SEARO regions.

Components, Models of Integration, and Outcomes Associated with Palliative/ end-of-Life Care Interventions in the Burn Unit: A Scoping Review

Objective: To scope the literature to ascertain the components of palliative care (PC) interventions for burn patients, models of integration, and outcomes. Methods: Arksey and O'Malley scoping review design with narrative synthesis was employed and reported following the PRISMA-ScR guidelines. Primary studies reporting PC interventions in the burn unit were considered for inclusion. CINAHL via EBSCO, PubMed, EMBASE via OVID, Web of Science, and gray literature sources were searched from inception to June 2021. Results: Fifteen studies emerging from high-income settings were retained. Data were organized around three concepts: components of palliative/ end of life care in the burn unit; models of integration; and outcomes. The components of interventions based on the Robert Wood Johnson Foundation Critical Care End-of Life Group domains include decision-making, communication, symptom management and comfort care, spiritual support, and emotional and practical support for families. Consultative and integrative models were noted to be the strategies for integrating PC in the burn unit. The outcomes were varied with only few studies reporting healthcare staff related outcomes. Conclusion: PC may have the potential of improving end-of-life care in the burn unit albeit the limited studies and lack of standardized outcomes makes it difficult to draw stronger conclusions regarding what is likely to work best in the burn unit.

Association of age with perioperative morbidity among patients undergoing surgical management of minor burns

Introduction

Burn injuries are associated with significant morbidity, often necessitating surgical management. Older patients are more prone to burns and more vulnerable to complications following major burns. While the relationship between senescence and major burns has already been thoroughly investigated, the role of age in minor burns remains unclear. To better understand differences between elderly and younger patients with predominantly minor burns, we analyzed a multi-institutional database.

Methods

We reviewed the 2008-2020 ACS-NSQIP database to identify patients who had suffered burns according to ICD coding and underwent initial burn surgery.

Results

We found 460 patients, of which 283 (62%) were male and 177 (38%) were female. The mean age of the study cohort was 46 ± 17 years, with nearly one-fourth (n = 108; 23%) of all patients being aged ≥60 years. While the majority (n = 293; 64%) suffered from third-degree burns, 22% (n = 99) and 15% (n = 68) were diagnosed with second-degree burns and unspecified burns, respectively. An average operation time of 46 min, a low mortality rate of 0.2% (n = 1), a short mean length of hospital stay (1 day), and an equal distribution of in- and outpatient care (51%, n = 234 and 49%, n = 226, respectively) indicated that the vast majority of patients suffered from minor burns. Patients aged ≥60 years showed a significantly prolonged length of hospital stay (p<0.0001) and were significantly more prone to non-home discharge (p<0.0001). In univariate analysis, advanced age was found to be a predictor of surgical complications (p = 0.001) and medical complications (p = 0.0007). Elevated levels of blood urea nitrogen (p>0.0001), creatinine (p>0.0001), white blood cell count (p=0.02), partial thromboplastin time (p = 0.004), and lower levels of albumin (p = 0.0009) and hematocrit (p>0.0001) were identified as risk factors for the occurrence of any complication. Further, complications were more frequent among patients with lower body burns.

Discussion

In conclusion, patients ≥60 years undergoing surgery for predominantly minor burns experienced significantly more complications. Minor lower body burns correlated with worse outcomes and a higher incidence of adverse events. Decreased levels of serum albumin and hematocrit and elevated values of blood urea nitrogen, creatinine, white blood count, and partial thromboplastin time were identified as predictive risk factors for complications.

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.

Comparative Analysis of Composite Mortality Prediction Scores in Intensive Care Burn Patients

Multiple outcome scoring models have been used in predicting mortality in burn patients. In this study, we compared the accuracy of five established models in predicting outcomes in burn patients admitted to the intensive care unit and assessed risk factors associated with mortality. Intensive care burn patients admitted between March 2007 and December 2020 with total body surface area (TBSA) affected ≥ 10% were analyzed. Multivariate analysis was conducted to examine variables associated with mortality. The ABSI, Ryan, BOBI, revised Baux and BUMP scores were analyzed by receiver operating characteristics. A total of 617 patients were included. Morality was 14.4%, with non-survivors being significantly older, male, and having experienced domestic burns. Multivariate analysis identified age, TBSA, full-thickness burns and renal insufficiency as independent mortality predictors. The BUMP score presented the highest mortality prognostication rate, followed by ABSI, revised Baux, BOBI and Ryan scores. BUMP, ABSI and revised Baux scores displayed AUC values exceeding 90%, indicating excellent prognostic capabilities. The BUMP score showed the highest accuracy of predicting mortality in intensive care burn patients and outperformed the most commonly used ABSI score in our cohort. The older models displayed adequate predictive performance and accuracy compared with the newest model.

Geriatric Burn Injuries Presenting to the Emergency Department of a Major Burn Center: Clinical Characteristics and Outcomes

BACKGROUND

Burn injuries in geriatric patients are common and may have significant associated morbidity and mortality. Most research has focused on the care of hospitalized patients after admission to burn units. Little is known about the clinical characteristics of geriatric burn victims who present to the emergency department (ED) and their ED assessment and management.

OBJECTIVE

Our aim was to describe the clinical characteristics and outcomes of geriatric patients presenting to the ED with burn injuries.

METHODS

We performed a comprehensive retrospective chart review on all patients 60 years and older with a burn injury presenting from January 2011 through September 2015 to a large, urban, academic ED in a hospital with a 20-bed burn center.

RESULTS

A total of 459 patients 60 years and older were treated for burn injuries during the study period. Median age of burn patients was 71 years, 23.7% were 80 years and older, and 56.6% were female. The most common burn types were hot water scalds (43.6%) and flame burns (23.1%). Median burn size was 3% total body surface area (TBSA), 17.1% had burns > 10% TBSA, and 7.8% of patients had inhalation injuries. After initial evaluation, 46.4% of patients were discharged from the ED. Among patients discharged from the ED, only 1.9% were re-admitted for any reason within 30 days. Of the patients intubated in the ED, 7.1% were extubated during the first 2 days of admission, and 64.3% contracted ventilator-associated pneumonia.

CONCLUSIONS

Better understanding of ED care for geriatric burn injuries may identify areas in which to improve emergency care for these vulnerable patients.

Wound Healing in Older Adults With Severe Burns: Clinical Treatment Considerations and Challenges

Background:

The older adult population continues to rapidly expand in number, with a projection by the United States (US) Census Bureau that there will be more individuals older than > 65 years (77.0 million) than those younger than < 18 years (76.5 million) by 2034. This review provides an overview of aging as it relates to wound healing and burn injuries in older adult patients, summarizes current treatment practices, and addresses the key challenges and considerations for treating severe burn injuries in this specific patient population.

Materials and methods:

A narrative literature search was conducted, focusing on recent primary literature on burns and wound healing in elderly patients.

Results:

Studies showed that the aging process results in both physiologic (eg, nutritional and metabolic status) and anatomic changes (eg, thinning dermis) that contribute to a reduced capacity to recover from burn-injury trauma compared with younger patients. Owing to impaired vision, decreased coordination, comorbidities, and medication-induced side effects, older adults (ie, > 65 years) are susceptible to severe burn injury (deep-partial thickness and full-thickness), which is associated with significant morbidity and mortality.

Conclusion:

A better understanding of the effects of age-related changes regarding wound healing in older adult patients who incur severe burn injuries may provide insight into clinical strategies to improve outcomes among this population.

Exploring The Background, Context And Stressors Of Caregiving To Elderly Burned Patients: A Qualitative Inquiry

Elderly persons are at risk of experiencing burns and require support from both formal and informal caregivers. Informal caregiving in this situation has been minimally explored. Guided by the Stress Process Model, this study aimed at exploring the background, context, and stressors of informal caregivers of elderly burned persons during hospitalisation. A qualitative descriptive design was utilised. Purposive sampling approach was used to recruit fourteen (14) informal caregivers who rendered care to elderly burned persons during hospitalisation. Interviews were conducted and transcribed verbatim following which directed content analysis was undertaken deductively. Three categories and six sub-categories emerged which characterise the background, context, and stressors of informal caregiving to elderly burn patients. All the injuries occurred in the home setting and its sudden nature led to varied post-burn emotional responses which characterised the context of burns caregiving. Primary stressors that emerged were related to the injury, actual caregiving demand, and concerns regarding increasing frailty levels. Secondary stressors identified were financial concerns and lifestyle changes. The findings suggest that the occurrence of burn injury served as a precursor to post-burn stress response among informal caregivers. Increasing frailty levels, adequacy of household safety measures and financial issues were key concerns which emphasise the need for psychosocial/ transitional support, innovative healthcare financing measures and continuing education on burns prevention in the home setting.

No Difference in Morbidity or Mortality Between Octogenarians and Other Geriatric Burn Trauma Patients

BACKGROUND

Geriatric burn trauma patients (age ≥65 years) have a 5-fold higher mortality rate than younger adults. With the population of the US aging, the number of elderly burn and trauma patients is expected to increase. A past study using the National Burn Repository revealed a linear increase in mortality for those >65 years old. We hypothesized that octogenarians with burn and trauma injuries would have a higher rate of in-hospital complications and mortality, than patients aged 65-79 years old.

METHODS

The Trauma Quality Improvement Program (2010-2016) was queried for burn trauma patients. To detect mortality risk a multivariable logistic regression model was used.

RESULTS

From 282 patients, there were 73 (25.9%) octogenarians and 209 (74.1%) aged 65-79 years old. The two cohorts had similar median injury severity scores (16 vs. 15 in octogenarians, P = .81), total body surface area burned (P = .30), and comorbidities apart from an increased smoking (12.9% vs. 4.1%, P = .04) and decreased hypertension (52.2% vs. 65.8%, P = .04) in the younger cohort. Octogenarians had similar complications, including acute respiratory distress syndrome, pulmonary embolism, deep vein thrombosis (P > .05), and mortality (15.1% vs. 10.5%, P = .30), compared to the younger cohort. Octogenarians were not associated with an increased mortality risk (odds ratio 1.51, confidence interval 0.24-9.56, P = .67).

DISCUSSION

Among burn trauma patients ≥65 years, age should not be a sole predictor for mortality risk. Continued research is necessary in order to determine more accurate approaches to prognosticate mortality in geriatric burn trauma patients, such as the validation and refinement of a burn-trauma-related frailty index.

A Systematic Review on Classification, Identification, and Healing Process of Burn Wound Healing

Because of the intrinsic complexity, the classification of wounds is important for the diagnosis, management, and choosing the correct treatment based on wound type. Generally, burn injuries are classified as a class of wounds in which injury is caused by heat, cold, electricity, chemicals, friction, or radiation. On the other hand, wound healing is a complex process, and understanding the biological trend of this process and differences in the healing process of different wounds could reduce the possible risk in many cases and greatly reduce the future damage to the injured tissue and other organs. The aim of this review is to provide a general perspective for the burn wound location among the other types of injuries and summarizing as well as highlighting the differences of these types of wounds with emphasizing on factors affecting thereof.
