Aetiology and outcome of burns in the elderly

The timing of death in burn patients

Aim

When treating burn patients, some patients die in the chronic phase, even if they overcome the acute phase of the burn. To elucidate the timing of death and its underlying causes among burn patients.

Methods

Patients evaluated were admitted to our burn center between January 2015, and December 2019. Patient information, time, and cause of death were retrospectively collected from their medical records.

Results

Among 342 admitted patients, 49 died. The time of death was as follows: within 24 h (n = 9), within 3 days (n = 7), within 1 week (n = 5), within 2 weeks (n = 4), within 3 weeks (n = 3), within 30 days (n = 6), within 60 days (n = 5), and after 60 days (n = 9). The causes of death within 3 days were hypoxic encephalopathy, extensive burns (>80%), severe heat stroke, and acute coronary syndrome. The causes of death after 3 days were sepsis, pneumonia, intestinal ischemia, pancreatitis, and worsening of chronic diseases. The mortality rate was similar for patients ≥65 years of age and those with a burn area of ≥20%, with both groups showing a particularly poor prognosis.

Conclusions

The timing of death in hospitalized burn patients showed a bimodal distribution as approximately 40% of patients who survived the resuscitation period died after 30 days. Elderly patients were at particularly high risk for mortality. In burn care, treatment planning should consider not only the short-term but also the long-term prognosis.

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.

The status quo of early burn wound excision: Insights from the German burn registry

BACKGROUND

There is a common, well-known and established recommendation to excise burn wounds within 24-72 h in order to mitigate the systemic inflammatory and immunomodulatory response, shorten length of hospitalization through early grafting and optimize patient survival. Despite this apparent consensus, surprisingly few systematic studies have evaluated the actual adherence to this practice and its implications on patient outcomes. In this registry study, we sought to objectify the current status of early burn wound excision, its influencing factors and impact on patient outcomes for all German burn centers.

METHODS

The German burn registry ('Deutsches Verbrennungsregister') was queried for 3 consecutive years for all patients, who received at least one surgical intervention. Patients were stratified based on whether the first surgical procedure was performed early (EE, within 72 h) or late (LE, after 72 h) post-burn. Descriptive statistics and univariate regressions were performed to quantify fraction of EE vs. LE and to evaluate factors which might favor one over the other (i.e. age, inhalation injury, burn severity by total body surface area (TBSA), scald vs. other burns, obesity, time of admission). Key patient outcomes were analyzed for each group (i.e. mortality, length of hospitalization, number of surgeries) and multifactorial regression analyses were carried out to model the impact of EE on mortality. Statistical significance was accepted at p < 0.05.

RESULTS

After initial screening, 1494 complete records were included for final analysis and were stratified into EE and LE. Only 670 (44%) underwent EE within 72 h. Increasing TBSA burned (i.e. [TBSA > 30%]: 53.8% EE, [TBSA < 30%]: 43.5% EE, p < 0.01) and admission on a weekday between Sunday and Wednesday were associated with higher probability of EE (51.5% EE) versus Thursday to Sunday (37.3%, p < 0.001). Age, inhalation injury, cause of burn, and obesity had no effect on EE vs. LE. Patients with EE had significantly shorter median lengths of hospitalization (EE: 18 d, LE: 21 d, p < 0.01). The median number of operations was comparable for both groups. Gross mortality appeared higher in the EE group, but turned out to be comparable to LE after correction for age, TBSA and sex in multifactorial regression analysis.

CONCLUSION

Despite apparent consensus among burn physicians, early excision of burn wounds is performed in less than 50% of cases in German burn centers. The relationship of EE to TBSA burned is expected and clinically sound, while a dependence on admission weekday raises administrative and infrastructural questions, especially when patients who receive EE have significantly shorter hospital stays. More analyses from other burn repositories are needed to compare and benchmark the international status quo of early burn wound excision.

The prognostic nutritional index on postoperative day one is associated with one-year mortality after burn surgery in elderly patients

BACKGROUND

Burn injury in elderly patients can result in poor outcomes. Prognostic nutritional index (PNI) can predict the perioperative nutritional status and postoperative outcomes. We aim to evaluate the risk factors, including PNI, for one-year mortality after burn surgery in elderly patients.

METHODS

Burn patients aged ≥65 years were retrospectively included. PNI was calculated using the following equation: 10 × serum albumin level (g/dL) + 0.005 × total lymphocyte count (per mm³). Cox regression, receiver operating characteristic curve and Kaplan-Meier survival analyses were performed to evaluate the risk factors for postoperative one-year mortality.

RESULTS

Postoperative one-year mortality occurred in 71 (37.6%) of the 189 elderly burn patients. Risk factors for one-year mortality were PNI on postoperative day one (hazard ratio (HR) = 0.872; 95% CI = 0.812-0.936; p < 0.001), Sequential Organ Failure Assessment score (HR = 1.112; 95% CI = 1.005-1.230; p = 0.040), American Society of Anesthesiologists physical status (HR = 2.064; 95% CI = 1.211-3.517; p = 0.008), total body surface area burned (HR = 1.017; 95% CI = 1.003-1.032; p = 0.015) and preoperative serum creatinine level (HR = 1.386; 95% CI = 1.058-1.816; p = 0.018). The area under the curve of PNI for predicting one-year mortality after burn surgery was 0.774 (optimal cut-off value = 25.5). Patients with PNI ≤25.5 had a significantly lower one-year survival rate than those with PNI >25.5 (32.1% vs 75.9%, p < 0.001).

CONCLUSIONS

PNI on postoperative day one was associated with postoperative one-year mortality in elderly burn patients. The postoperative one-year survival rate was lower in patients with PNI ≤25.5 than in those with PNI >25.5. These findings indicate the importance of identifying elderly burn patients with low PNI, thereby reducing the mortality after burn surgery.

Burns in the elderly: a nationwide study on management and clinical outcomes

Background

In modern-day burn care, advanced age remains an important predictor for mortality among burn victims. In this study, we compared the complete treatment trajectory (including pre-hospital and surgical treatment) and the outcomes between an elderly burn population and a younger adult burn population.

Methods

In this nationwide study, data from the Dutch Burn Repository were used. This is a uniform national registration for Dutch specialized burn care. All adult patients that were admitted to one of the three Dutch burn centres from the period 2009 to 2015 were included in the analysis. Burn patients were considered as elderly when ≥65 years of age, and were then further subdivided into three age categories: 65-74, 75-85 and 85+ years. Younger adults in the age category 18-64 years were used as the reference group.Surgical management was studied comprehensively and included timing of surgery, the number of procedures and details on the surgical technique, especially the technique used for debridement and the grafting technique that was applied.For the comparison of clinical outcome, the following parameters were included: mortality, wound infections, length of stay/TBSA (total body surface area) burned, discharge disposition and secondary reconstructions.

Results

During the study period, 3155 adult patients were included (elderly, n = 505). Burn severity, reflected by the median TBSA, varied between 3.2-4.0% and was comparable, but aetiology and pre-hospital care were different between elderly and the younger adult reference group.Surgical treatment was initiated significantly faster in elderly burn patients (p < 0.001). Less selective techniques for surgical debridement were used in the elderly burns patients (hydrosurgery, 42.0% vs 23.5-22.6%), and on the other hand more avulsion (5.3% vs 7.3-17.6%) and primary wound closure (6.7% vs 24.5%). The most frequently used grafting technique was meshed skin grafts (79.2-88.6%); this was not related to age.Mortality increased rapidly with a higher age and showed a high peak in the 85+ category (23.8%). Furthermore, considerable differences were found in hospital discharge disposition between the elderly and the reference group.

Conclusions

In conclusion, elderly burn patients who require specialized burn care are vulnerable and medically challenging. Differences in aetiology, comorbidity, physiology and the management prior to admission possibly affect the initial surgical management and result in significantly worse outcomes in elderly. Elderly patients need optimal, timely and specialized burn care to enhance survival after burn injuries.

Early Enteral Nutrition in Geriatric Burn Patients: Is There a Benefit?

Nutrition is a critical component of acute burn care and wound healing. There is no consensus over the appropriate timing of initiating enteral nutrition in geriatric burn patients. This study aimed to assess the impact of early enteral nutrition on outcomes in this patient population. We performed a 1-year (2017) analysis of the American College of Surgeons Trauma Quality Improvement Program and included all older adult (age ≥65 years) isolated thermal burn patients who were admitted for more than 24 hr and received enteral nutrition. Patients were stratified into two groups based on the timing of initiation of feeding: early (≤24 hr) vs late (>24 hr). Multivariate logistic regression was performed to control for potential confounding factors. Outcome measures were hospital and intensive care unit lengths of stay, in-hospital complications, and mortality. A total of 1,004,440 trauma patients were analyzed, of which 324 patients were included (early: 90 vs late: 234). The mean age was 73.9 years and mean TBSA burnt was 31%. Patients in the early enteral nutrition group had significantly lower rates of in-hospital complications and mortality (15.6% vs 26.1%; P = 0.044), and a shorter hospital length of stay (17 [11,23] days vs 20 [14,24] days; P = 0.042) and intensive care unit length of stay (13 [8,15] days vs 17 [9,21] days; P = 0.042). In our regression model of geriatric burn patients, early enteral nutrition was associated with improved outcomes. The cumulative benefits observed may warrant incorporating early enteral nutrition as part of intensive care protocols.

Medical and biological factors affecting mortality in elderly residential fire victims: a narrative review of the literature

For older people (aged over 65 years), the risk of dying in a residential fire is doubled compared to the general population. Obvious causes of death mainly include smoke inhalation and burn injuries. That older people are more fragile and have more concurrent diseases is inherent, but what is it that makes them more vulnerable? It is known that the number of elderly people is increasing globally and that the increased risk of death in fires can be explained, at least in part, by physical and/or cognitive disabilities as well as socioeconomic and behavioural factors. The possibility that medical illnesses and an aging organism/tissues might explain this increased risk has not been shown to the same extent. Therefore, this narrative literature review focuses on medical and biological explanations. An initial search using the terms ‘elderly’, ‘fatal’, ‘residential’ and ‘fire’ yielded some interesting articles. Using a broader snowball search also accepting grey literature, several additional risk factors could be identified. Cardiovascular diseases, in particular atherosclerotic heart disease, greatly increases the vulnerability to, for example, carbon monoxide and probably also other asphyxiating gases. Cardiovascular diseases and lack of physical fitness may also increase vulnerability to heat. Burned elderly patients are also at a higher risk of death than younger patients, but it is controversial whether it is age itself or the pre-existing illnesses that come with age that increase the risk. Immunosenescence, malnutrition and female gender are other risk factors for poorer outcome after burns, all of which are common among older people.

Elderly people have an increased risk of dying in house fires for several known reasons. This review explores possible medical/biological explanations and finds heart disease to be an important explanation.

Factors associated with length of hospital stay in minor and moderate burns at Popayan, Colombia. Analysis of a cohort study

OBJECTIVE

To determine the independent contribution of prognostic factors to length of hospital stay of minor and moderate burn victims at the Hospital Universitario San José (HUSJ), Popayán, Colombia, 2000-2010.

METHODS

This was a retrospective cohort study of minor and moderate burn victims admitted between 2000 and 2010, at the burn unit (HUSJ). This is a further analysis of a same cohort previously published in Burns. The following variables were recorded and analyzed: age, gender, origin, depth and extent of burn, causal agent, length of hospital stay and mortality. The main outcome under study was length of stay. Survival analysis was done to explore the association of covariates and length of hospital stay and Cox regression model to adjust the effect of covariates in the outcome.

RESULTS

During the study period 2000-2010, 842 of 921 (91.5%) patients treated at the Burn Unit of HUSJ that had complete data were included. There were 520 (61.8%) males and 322 (38.2%) females with a male to female ratio of 1.6:1. Their median age was 9 years (IQR 3-28). The median of percent total body surface area burned (TBSA) was 12% (IQR 7-21) and the most common degree of burn was 2nd degree with 58% (488 patients). There were 12 deaths (censored data) and 830 patients were discharged alive. After multivariate adjustment, significant associations with length of hospital stay remained for age group, burn degree and extension of the burn. The strongest relationship found was for burn degree (2nd degree superficial vs. 3rd degree hazard ratio=2.66 CI 95% [2.13-3.33]).

CONCLUSIONS

In patients admitted with mild and moderate burns at HUSJ, the main predictors of length of stay were age, burn degree and extension of the burn.

Virtual restorative environment therapy as an adjunct to pain control during burn dressing changes: study protocol for a randomised controlled trial

BACKGROUND

The pain of a severe burn injury is often characterised by intense background pain, coupled with severe exacerbations associated with essential procedures such as dressing changes. The experience of pain is affected by patients' psychological state and can be enhanced by the anxiety, fear and distress caused by environmental and visual inputs. Virtual Reality (VR) distraction has been used with success in areas such as burns, paediatrics and oncology. The underlying principle of VR is that attention is diverted from the painful stimulus by the use of engaging, dynamic 3D visual content and associated auditory stimuli. Functional magnetic resonance imaging (fMRI) studies undertaken during VR distraction from experimental pain have demonstrated enhancement of the descending cortical pain-control system.

METHODS/DESIGN

The present study will evaluate the feasibility of introducing a novel VR system to the Burns Unit at the Queen Elizabeth Hospital Birmingham for dressing changes: virtual restorative environment therapy (VRET). The study will also explore the system's impact on pain during and after the dressing changes compared to conventional analgesia for ward-based burn dressing changes. A within-subject crossover design will be used to compare the following three conditions: 1. Interactive VRET plus conventional analgesics. 2. Passive VRET with conventional analgesics. 3. Conventional analgesics alone. Using the Monte Carlo method, and on the basis of previous local audit data, a sample size of 25 will detect a clinically significant 33 % reduction in worst pain scores experienced during dressing changes.

DISCUSSION

The study accrual rate is currently slower than predicted by previous audits of admission data. A review of the screening log has found that recruitment has been limited by the nature of burn care, the ability of burn inpatients to provide informed consent and the ability of patients to use the VR equipment. Prior to the introduction of novel interactive technologies for patient use, the characteristics and capabilities of the target population needs to be evaluated, to ensure that the interface devices and simulations are usable.

Outcomes of burns in the elderly: revised estimates from the Birmingham Burn Centre

Outcomes after burn have continued to improve over the last 70 years in all age groups including the elderly. However, concerns have been raised that survival gains have not been to the same magnitude in elderly patients compared to younger age groups. The aims of this study were to analyze the recent outcomes of elderly burn injured patients admitted to the Birmingham Burn Centre, compare data with a historical cohort and published data from other burn centres worldwide. A retrospective review was conducted of all patients ≥65 years of age, admitted to our centre with cutaneous burns, between 2004 and 2012. Data was compared to a previously published historical cohort (1999-2003). 228 patients were included. The observed mortality for the study group was 14.9%. The median age of the study group was 79 years, the male to female ratio was 1:1 and median Total Body Surface Area (TBSA) burned was 5%. The incidence of inhalation injury was 13%. Median length of stay per TBSA burned for survivors was 2.4 days/% TBSA. Mortality has improved in all burn size groups, but differences were highly statistically significant in the medium burn size group (10-20% TBSA, p≤0.001). Burn outcomes in the elderly have improved over the last decade. This reduction has been impacted by a reduction in overall injury severity but is also likely due to general improvements in burn care, improved infrastructure, implementation of clinical guidelines and increased multi-disciplinary support, including Geriatric physicians.

Safety and efficacy of excision and direct closure in acute burns surgery: outcome analysis in a prospective series of 100 patients and a survey of UK burns surgeons' attitudes

Many burns surgeons avoid excision and direct closure of acute burns owing to concerns over wound dehiscence, scarring and infection. There is no evidence in the literature to support this practice. We present outcomes of a prospective series of 100 patients who underwent excision and direct closure of 138 burns over a 2-year period, along with results from a survey sent to 33 senior burns surgeons to gauge attitudes towards direct closure in burns surgery. 47% of survey respondents never perform direct closure. Dehiscence was cited as the most common concern, followed by hypertrophic scarring (HTS). In our cohort, the superficial dehiscence rate was 12% and the HTS rate was 16%, with no scarring contractures. Patients with healing time greater than 14 days were more likely to develop HTS (p=0.008), as were those with wound dehiscence (p=0.014). Patients undergoing part-grafting in addition to direct closure took significantly longer to heal than those undergoing direct closure alone (p=0.0002), with the donor site or graft delaying healing in the majority. Excision and direct closure of acute burn wounds avoids donor site morbidity and has an acceptable complication rate. It is a safe and effective treatment for full thickness burns in selected cases.

Assessment of mortality prediction models in a Ghanaian burn population

PURPOSE

Over 40 new or modified outcome prediction models have been developed for severe burns; with age, total burned surface area (TBSA) and inhalation area as major determinants of mortality. The objective of this study was to assess their applicability in a developing country.

PROCEDURES

Data were collected retrospectively of a consecutive series of 261 patients (2009-2011) admitted to a Burns Intensive Care. Five outcome prediction models based on admission criteria were evaluated: Bull grid, Abbreviated Burn Severity Index--ABSI, Ryan-model, Belgian Outcome in Burn Injury--BOBI and revised Baux. Discriminative power and goodness-of-fit were assessed by receiver operating characteristic analyses (area under the curve--AUC) and Hosmer-Lemeshow tests.

FINDINGS

Median age was 10.5 years (IQR: 2.5-27 years), median TBSA 21% (IQR: 11-34%); 55.2% were male, 28 patients died (10.7%). Only 2 patients were intubated (0.8%). The AUC were between 77 and 86%. The ABSI model showed the best calibration (28.7 expected deaths). Ryan, BOBI and rBaux significantly underestimated mortality, whereas Bull showed an overestimation.

CONCLUSION

This study on a young group of burn patients showed moderate to good discriminative power using all five prediction models. The expected number of deaths tended to be underestimated in the three most recent prediction models.

Predicting resource utilization of elderly burn patients in the baby boomer era

BACKGROUND

Census predictions for Florida suggest a 3-fold increase in the 65 and older population within 20 years. We predict resource utilization for burn patients in this age group.

METHODS

Using the Florida Agency for Healthcare Administration admission dataset, we evaluated the effect of age on length of stay, hospital charges, and discharge disposition while adjusting for clinical and demographic factors. Using US Census Bureau data and burn incidence rates from this dataset, we estimated future resource use.

RESULTS

Elderly patients were discharged to home less often and were discharged to short-term general hospitals, intermediate-care facilities, and skilled nursing facilities more often than the other age groups (P < .05). They also required home health care and intravenous medications significantly more often (P < .05). Their length of stay was longer, and total hospital charges were greater (P < .05) after adjusting for sex, race, Charleson comorbidity index, payer, total body surface area burned, and burn center treatment.

CONCLUSIONS

Our data show an age-dependent increase in the use of posthospitalization resources, the length of stay, and the total charges for elderly burn patients.

A new algorithm to allow early prediction of mortality in elderly burn patients

INTRODUCTION

The elderly are the fastest growing population segment, and particularly susceptible to burns. Predicting outcomes for these patients remains difficult. Our objective was to identify early predictors of mortality in elderly burn patients.

METHODS

Our Burn Center's prospective database was reviewed for burn patients 60+ treated in the past 10 years. Predictor variables were identified by correlative analysis and subsequently entered into a multivariate logistic regression analysis examining survival to discharge.

RESULTS

203 patients of 1343 (15%) were eligible for analysis. The average age was 72 ± 10 (range 60-102) and the average total body surface area (TBSA) burned was 23 ± 18% (range 1-95). Age, TBSA, base deficit, pO(2), respiratory rate, Glasgow Coma Score (GCS), and Revised Trauma Score (RTS, based on systolic blood pressure, respiratory rate, and GCS) all correlated with mortality (p ≤0 .05). Using multiple logistic regression analysis, a model with age, TBSA and RTS was calculated, demonstrating: In this model, β(0) is a constant that equals -8.32.

CONCLUSIONS

Predicting outcomes in elderly burn patients is difficult. A model using age, TBSA, and RTS can, immediately upon patient arrival, help identify patients with decreased chances of survival, further guiding end-of-life decisions.

Epidemiologic investigation of burns in the elderly in Sichuan Province

OBJECTIVE

This study analysed the epidemiology of burns in the elderly in Sichuan Province, China, with the objective of formulating a prevention programme.

METHODS

A retrospective review of elderly patients admitted to the Burn Centre of West China Hospital during 2003-2009 was performed, including patient demographics, education and burn aetiology.

RESULTS

A total of 103 patients, mean age 69.5 years (range 60-95 years; 58 male, 45 female) were admitted. The most common causes of burn were flames (51.5%), scalding (37.9%), electrical (4.9%) and chemical (2.9%), respectively. The majority occurred at home (68.9%), principally in the kitchen (35.9%), while 19.4% occurred in the workplace. Burns with total body surface area (TBSA) of 0-10% accounted for 52.5% of those admitted for treatment; 10-30% TBSA burns accounted for 20.3%; 30-50% TBSA burns accounted for 15.5%; and burns with a TBSA >50% accounted for 11.7%. Only 6% of patients received appropriate first aid, and 32% did not receive treatment until more than 24h after injury. The education level was lower in the rural group. Both urban and rural groups had little knowledge of first aid for burns.

CONCLUSIONS

Burn-prevention programmes should promote improved living conditions and medical insurance, with prevention education for the elderly, especially in rural areas.

The emergency management and treatment of severe burns

Burn injuries continue to cause morbidity and mortality internationally. Despite international collaborations and preventative measures, there are still many cases reported in high- and low-income countries. The treatment of these patients is often protracted and requires extensive resources. The adequate resuscitation of these patients coupled with meticulous wound care can have a huge impact on their outcome. The authors present a simple guideline for the initial management of severe burns which is utilised by the South African Burn Society and is based on the guidelines of the American Burn Association and the Australian and New Zealand Burn Association.

Severe burn injury in Europe: a systematic review of the incidence, etiology, morbidity, and mortality

INTRODUCTION

Burn injury is a serious pathology, potentially leading to severe morbidity and significant mortality, but it also has a considerable health-economic impact. The aim of this study was to describe the European hospitalized population with severe burn injury, including the incidence, etiology, risk factors, mortality, and causes of death.

METHODS

The systematic literature search (1985 to 2009) involved PubMed, the Web of Science, and the search engine Google. The reference lists and the Science Citation Index were used for hand searching (snowballing). Only studies dealing with epidemiologic issues (for example, incidence and outcome) as their major topic, on hospitalized populations with severe burn injury (in secondary and tertiary care) in Europe were included. Language restrictions were set on English, French, and Dutch.

RESULTS

The search led to 76 eligible studies, including more than 186,500 patients in total. The annual incidence of severe burns was 0.2 to 2.9/10,000 inhabitants with a decreasing trend in time. Almost 50% of patients were younger than 16 years, and ~60% were male patients. Flames, scalds, and contact burns were the most prevalent causes in the total population, but in children, scalds clearly dominated. Mortality was usually between 1.4% and 18% and is decreasing in time. Major risk factors for death were older age and a higher total percentage of burned surface area, as well as chronic diseases. (Multi) organ failure and sepsis were the most frequently reported causes of death. The main causes of early death (< 48 hours) were burn shock and inhalation injury.

CONCLUSIONS

Despite the lack of a large-scale European registration of burn injury, more epidemiologic information is available about the hospitalized population with severe burn injury than is generally presumed. National and international registration systems nevertheless remain necessary to allow better targeting of prevention campaigns and further improvement of cost-effectiveness in total burn care.

The characteristics of elderly burns in Shanghai

OBJECTIVE

This study aims to analyse the epidemiologic characteristics of severe burn in the elderly in Shanghai and to discusses a possible prevention programme for this population.

METHODS

A retrospective review of all medical records of elderly patients (aged 60 and older) admitted with acute burns to the Burn Center of the RuiJin Hospital between January 1996 and December 2004 was carried out. Patient demographics, etiology of burn, mechanism of injury, burn extent, anatomical areas burned, number of operations, and outcomes were reviewed.

RESULTS

A total of 201 (5.8% of hospitalised patients) elderly patients (mean age (+/-SD) of 69.3+/-7.1 years (range 60-90 years)) were admitted. Majority of the patients were men (62.2%) and the most common etiologies were flames (52.7%) and scalds (39.8%). The majority of burns occurred at home (73.6%), followed by burns at workplace (15.9%) and public areas (10.5%). The median total body area burned was 11.7% (range 0-84%), and the majority of burns were classified as mild (60.2%) and moderate (32.8%). Predominant anatomical areas involved were the legs (76.1%), arms (67.2%), head and neck (49.8%) and hands (49.3%). The most common pre-injury conditions were cardiovascular diseases (25.9%), diabetes (8.5%) and neurological diseases (6%). Eighty-seven patients (43.3%) required surgical treatment. The most common complications were multiple organ failure (2%), pneumonia (1%) and wound infection (1%). Sixteen patients (8%) died: half of them in hospital, and the rest at home. There was a significant correlation between post-injury complications and death (r=0.69, p<0.001). The mean total hospitalisation cost was yen 22993.09 (US$ 3381.34).

CONCLUSIONS

Domestic and workplace burns with devastating consequences are very common in the elderly population in Shanghai. Burn prevention education and implementation of safety measures at home and at workplace would help reduce such incidences.

Burn treatment in the elderly

The population of elderly patients is expected to rise continuously over the next decades due to global demographic changes. The elderly seem to be most vulnerable to burns and their management remains undoubtedly a challenge. A clear age margin for elderly patients is not yet defined, but most studies adhere to the inclusion of patients 65 years and above, but the general condition and social situation must be taken into account. The understanding of the physiological basis of aging and its related pathophysiological changes has only marginally influenced treatment and decision making in elderly burn patients. When looking at treatment regimens currently applied in elderly burn patients, the discussion of standards in intensive care as well as surgical strategies is ongoing. However, trends towards a moderate, non-aggressive resuscitation approach and careful inclusion of key parameters like physiological age, pre-burn functional status and premorbid conditions, seem to be useful guidelines for interdisciplinary treatment decisions. Once ordered for surgical treatment, the amount of body surface area operated in one session should be adapted to the general status of the patient. Even if older burn victims have a reported higher mortality rate than younger patients, improved therapeutic options have contributed to a reduced mortality rate even in the elderly over the last decades. As a result of improved outcome, more attention has to be given to a comprehensive rehabilitation program. This review will give an overview of the current literature and will draw attention to specific topics related to this important subpopulation of burn patients.

Influence of comorbidities and age on outcome following burn injury in older adults

Despite advances in medical and surgical techniques, older adults tend to be at high risk for adverse outcomes following burn injury. The purpose of this study was to examine the relative impacts of age and medical comorbidities on outcome following injury in a cohort of older adults. This was a retrospective study of all patients age 55 and over admitted to the University of Washington Burn Center from 1999 to 2003. To examine the effect of baseline medical comorbidities on outcome, a Charlson Comorbidity Index score was calculated for each patient. Multivariate regression analyses were used to examine the impact of age and comorbidities on mortality and other complications. Patient records were also matched with the National Death Index to determine the effects of age and comorbidities on mortality within 1 year following hospital discharge. A total of 325 patients who were of 55 years and older were admitted to the burn center during the 5-year study period. The overall mortality rate was 18.5%. Mortality was independently associated with age, inhalation injury, and burn size. One-year mortality was significantly associated with those older than age 75 and the Charlson score. Longer length of stay was significantly associated with burn size, inhalation injury, and total number of in-hospital complications. This study demonstrates that patient age-independent of baseline medical comorbidities-and TBSA burn are the most significant factors impacting in-hospital mortality risk following burn injury. Higher number of medical comorbidities was associated with increased mortality risk within 1 year following discharge.

Epidemiology and outcomes of older adults with burn injury: an analysis of the National Burn Repository

Improvements in outcomes for older adults sustaining burn injuries have lagged far behind those of younger patients. As this segment of the population grows, there has been an increasing interest in better understanding the epidemiology and outcomes of injury in older adults. The National Burn Repository (NBR) provides a unique opportunity to examine burn injuries on a national level. We aimed to characterize specific injury and outcome trends in older adult with burns through analysis of the NBR. We examined the records of all patients in the NBR aged 55 and older. To characterize age effects on injury and outcomes, patients were stratified into three age categories: 55 to 64 years, 65 to 74 years, and 75 years and older. Baseline characteristics, details of hospital treatment, mortality, and disposition were compared among these three age groups using chi or analysis of variance. Logistic regression analysis was performed to assess the impact of age on burn mortality. A total of 180,401 patient records were available from 1991 to 2005, of which 23,180 (14%) met age inclusion criteria. Mean burn size (9.6% TBSA) and percent with inhalation injury (11.3%) did not markedly differ by age. Men predominated overall (ratio 1.4:1), although women (4290) outnumbered men (3439) in the oldest age category. Length of stay per TBSA and median hospital charges increased with increasing age category, suggesting higher resource consumption with aging. Mean number of operations per patient, however, decreased with age. Mortality rates and discharge to nonindependent status increased with age. By logistic regression, the adjusted odds ratio for mortality was 2.3 (95% CI 2.1-2.7) in the 65 to 74 age group, and 5.4 (95% CI 4.8-6.1) in the oldest group when compared with the 55 to 64 age group. Mortality rates decreased significantly after 2001 across all age groups. This analysis demonstrates age-dependent differences in resource utilization and mortality risk within the older burn population and highlights the need for a national research agenda focused on management practices and outcomes in older adult with burns.

Elderly burn prevention: A novel epidemiological approach

OBJECTIVE

To develop burn prevention strategies for the elderly population in Hong Kong using a novel epidemiological approach.

METHODS

Medical records of all patients aged 60 or above who were admitted to our hospital in a 6-year period were reviewed and demographic data, injury characteristics, details of management and outcome were obtained. Selected interviews were undertaken to determine the exact mechanisms of injury and further details of the medical and social background.

RESULTS

Fifty-nine elderly patients were identified from the medical records with under half (42%) aged 75 and above. Male to female ratio was 1:1.68. Three-quarters of the injuries occurred at home, principally in the kitchen and bathroom. Two-thirds of the burns were scalds. Forty-eight percent of the admitted patients had surgery. Thirty-seven patients (or next of kin) were interviewed further. Of the subgroup only 12% had received appropriate first aid and 27% had treatment delayed for over 24 h before seeking medical help. The majority of patients had little or no formal education and one quarter were living alone.

CONCLUSION

We identified common scenarios of elderly burns which could be used to focus prevention strategies.
