The demographics of modern burn care: should most burns be cared for by non-burn surgeons?

Health systems research in burn care: an evidence gap map

BACKGROUND

Burn injury is associated with significant mortality and disability. Resilient and responsive health systems are needed for optimal response and care for people who sustain burn injuries. However, the extent of health systems research (HSR) in burn care is unknown. This review aimed to systematically map the global HSR related to burn care.

METHODS

An evidence gap map (EGM) was developed based on the World Health Organization health systems framework. All major medical, health and injury databases were searched. A standard method was used to develop the EGM.

RESULTS

A total of 6586 articles were screened, and the full text of 206 articles was reviewed, of which 106 met the inclusion criteria. Most included studies were cross-sectional (61%) and were conducted in hospitals (71%) with patients (48%) or healthcare providers (29%) as participants. Most studies were conducted in high-income countries, while only 13% were conducted in low-and middle-income countries, accounting for 60% of burns mortality burden globally. The most common health systems areas of focus were service delivery (53%), health workforce (33%) and technology (19%). Studies on health policy, governance and leadership were absent, and there were only 14 qualitative studies.

CONCLUSIONS

Major evidence gaps exist for an integrated health systems response to burns care. There is an inequity between the burden of burn injuries and HSR. Strengthening research capacity will facilitate evidence-informed health systems and policy reforms to sustainably improve access to affordable, equitable and optimal burn care and outcomes.

Factors influencing the implementation of best practice in burn care in Western Australia

AIMS AND OBJECTIVES

The study aimed to determine the factors which influence clinician behaviour and adherence to best practice when clinicians provide the initial care for paediatric burn patients admitted to a burns unit.

BACKGROUND

Optimal initial care of burn patients influences morbidity and mortality. Non-burn specialist clinician adherence to best practice is influenced by previously unexplored factors.

DESIGN

General inductive qualitative methods were used to explore factors which influenced clinicians providing acute pre-admission burn care for children in Western Australia.

METHODS

Interviews of nineteen clinicians using standardised open-ended questions based on the Gilbert Behaviour Engineering Model were used to collect data.

RESULTS

The main influencing factors identified were the telehealth service which supported practice, whilst IT issues provided challenges to clinicians.

CONCLUSION

Telehealth services support clinicians when providing burn care, however IT issues are an major barrier to both best practice and accessing the telehealth service and should be optimised to support clinical care IMPACT STATEMENT: What does this paper contribute to the wider global community? It provides burn clinicians with an insight into the factors which facilitate optimal care for patients prior to transfer to burn units, as well as the barriers faced by non-burn specialist clinicians when patients initially present for care. Models of care which acknowledge these factors can help facilitate optimal patient care.

North American pediatric surgery fellows' preparedness for humanitarian surgery

INTRODUCTION

The overwhelming burden of pediatric surgical need in humanitarian settings has prompted mutual interest between humanitarian organizations and pediatric surgeons. To assess adequate fit, we correlated pediatric surgery fellowship case mix and load with acute pediatric surgical relief efforts in conflict and disaster zones.

METHODS

We reviewed pediatric (age < 18) cases logged by the Médecins Sans Frontières Operational Centre Brussels (MSF-OCB) from a previously validated and published database spanning 2008-2014 and cases performed by American College of Graduate Medical Education (ACGME) pediatric surgery graduates from 2008 to 2018. Non-operative management for trauma, endoscopic procedures, and basic wound care were excluded as they were not tracked in either dataset. ACGME procedures were classified under 1 of 32 MSF pediatric surgery procedure categories and compared using chi-squared tests.

RESULTS

ACGME fellows performed procedures in 44% of tracked MSF-OCB categories. Major MSF-OCB pediatric cases were comprised of 62% general surgery, 23% orthopedic surgery, 9% obstetrical surgery, 3% plastic/reconstructive surgery, 2% urogynecologic surgery, and 1% specialty surgery. In comparison, fellows' cases were 95% general surgery, 0% orthopedic surgery, 0% obstetrical surgery, 5% urogynecologic surgery, and 1% specialty surgery. Fellows more frequently performed abdominal, thoracic, other general surgical, urology/gynecologic, and specialty procedures, but performed fewer wound and burn procedures (all p < 0.05). Fellows received no experience in Cesarean section or open fracture repair. Fellows performed a greater proportion of surgeries for congenital conditions (p < 0.05).

CONCLUSION

While ACGME pediatric surgical trainees receive significant training in general and urogynecologic surgical techniques, they lack sufficient case load for orthopedic and obstetrical care - a common need among children in humanitarian settings. Trainees and program directors should evaluate the fellow's role and scope in a global surgery rotation or provide advanced preparation to fill these gaps. Upon graduation, pediatric surgeons interested in humanitarian missions should seek out additional orthopedic and obstetrical training, or select missions that do not require such skillsets.

Western Trauma Association critical decisions in trauma: Preferred triage and initial management of the burned patient

This is a recommended management algorithm from the Western Trauma Association addressing the management of victims of burn injury. Because there is a paucity of published prospective randomized clinical trials that have generated Class I data, these recommendations are based primarily on published retrospective studies, clinical guidelines, and the expert opinion of members of the Western Trauma Association in conjunction with partner members of the American Burn Association. The algorithm and accompanying comments represent one safe and sensible approach that can be followed at most trauma centers. We recognize that there may be patient or institutional factors that warrant deviation from the published algorithm. We would encourage institutions to use this document as a starting point toward a dialog with local burn centers to collaboratively create a patient-centered care experience for the victims of minor burn injuries arriving at local trauma centers.

Intoxication and Flame Burn Injuries in Young Adults in the United States

Flame injuries are the primary cause of burns in young adults. Although drug and alcohol intoxication has been associated with other types of trauma, its role in burn injury has not been well described in this population. The purpose of this study was to investigate the association of intoxication and flame burn injuries in young adults in the United States. The 2014 Nationwide Emergency Department Sample was queried for burn injury visits of young adult patients, 13-25 years old. This data is weighted to allow for national estimates. Burn mechanism and intoxication status were determined by International Classification of Diseases, Ninth Revision codes. Multivariable logistic regression analysis was used to assess the association of intoxication and emergency department (ED) visits due to flame burns, adjusting for patient age, gender, zip code median income, zip code rural-urban designation, timing of visit, and hospital region. Further analyses assessed the odds of admission or transfer, as a possible proxy of injury severity, in patients with flame or other burns, with and without intoxication adjusting for patient age, gender, primary insurance, and hospital trauma designation. There were 20,787 visits for patients 13-25 years old with burn injuries and 12.9% (n = 2678) had a codiagnosis of intoxication. There was an increasing proportion of intoxication by age (5.8% 13-17 years old, 25% 18-20 years old, 69% 21-25 years old, P < .001). ED visits for burns with a codiagnosis of intoxication had 1.34 times ([95% confidence interval (CI): 1.18, 1.52], P < .01) higher odds of having flame burns compared to other burn mechanisms. Those with flame burns and intoxication were most likely to be admitted or transferred when compared to nonflame, nonintoxication visits in the adjusted model (odds ratio [OR] 5.49, [95% CI: 4.29, 7.02], P < .01). Furthermore, the odds of admission or transfer in visits with the combined exposure of intoxication and flame mechanism were significantly higher than visits due to nonflame burns and intoxication (OR 2.75, [2.25, 3.36], P < .01) or flame burns without intoxication (OR 3.00, [95% CI: 2.61, 3.42], P < .01). This study identified a significant association between flame-burn-related ED visits and intoxication in the young adult population in the United States. In addition, the combination of flame mechanism and intoxication appears to result in more substantial injury compared with either exposure alone. The relationship seen between intoxication and flame burn injury underscores a major target for burn prevention efforts in the young adult population.

A third of referrals are unnecessary: Critical review of burn outpatient clinic data

OBJECTIVES

The purpose of this study was to establish patterns in types of burns referred to the Outpatient Clinic (OP) at Vancouver General Hospital (VGH).

METHODS

A 2-year retrospective chart review was conducted of patients presenting to the OP Clinic from June 1, 2016 - June 1, 2018. Data collected included: patient demographics, depth of burn, Total Body Surface Area (TBSA), anatomical location of burn, geographical location of referral, and operative versus non-operative management.

RESULTS

The OP Clinic served 470 patients for burn injuries with a total of 1852 visits. Of these, 20% were follow-up visits post-admission, and 73.6% were primary referrals from the emergency department (ED) or elsewhere. The vast majority (69.6%) of burns were less than 5% TBSA. Half involved the hands (50.9%), and half were superficial dermal in depth (45.1%). A third of patients attended only one appointment with the OP Clinic before discharge and 15% did not receive any treatment.

CONCLUSIONS

The results of our study demonstrate gaps in current provincial referral guidelines leading to a significant number of "unnecessary referrals." Further research could correlate the results to current provincial referral guidelines to estimate their current efficacy in practical use.

Initial Assessment, Treatment, and Follow-Up of Minor Pediatric Burn Wounds in Four Patients Remotely: A Preliminary Communication

BACKGROUND

Close, multidisciplinary collaboration with burn experts is the essential strategy to achieve the best functional and esthetic outcomes in burn wound treatment. Management of minor burn injuries, where no specialized care is available, might be challenging. One concept to achieve a fast and timely result is the application of telemedicine. The objective of this study was to assess and develop a simple telemedicine protocol, which can be applied globally.

MATERIAL AND METHODS

We present a pilot study based on a pediatric population of four patients with minor burns. Based on the severity and burn area, two cases of ambulant pediatric patients (mean 1% total body surface area, superficial and deep 2° burn) with minor burn injuries met study criteria and were enrolled. A pediatrician performed the initial assessment, followed by plastic surgery video consultation, using telephone's digital camera. Treatment protocols were designed to optimize outcomes. After the initial treatment phase, which took place at a nonteaching local hospital in Poland from January 1, 2014, to December 31, 2014, clinical follow-up was performed by a plastic surgeon via smartphone in the United States.

RESULTS

We have achieved complete burn wound resolution, in all patients, with no scarring and only minor discoloration. A simple, reproducible treatment protocol was designed to include dressing changes and additional outpatient visits.

CONCLUSIONS

Implementation of a telemedicine protocol allows for easy access to burn consultations, helps multidisciplinary collaboration, eases follow-ups, and shortens specialists' consult wait times. Real-time evaluation provides fast and flexible treatment, without long distance travels, for patients and their families. Telemedicine increases the frequency of follow-up, contributes to the esthetic outcome, and together with improved cost-effectiveness is beneficial for both the patient and healthcare system.

Prehospital Care of Burn Patients and Trajectories on Survival

We sought to identify factors associated with the prognosis and survival of burn patients by analyzing data related to the prehospital treatment of burn patients transferred directly to the burn unit from the accident site. We also aimed to assess the role of prehospital physicians and paramedics providing care to major burn patients. This study included adult burn patients with severe burns treated between 2006 and 2010. Prehospital patient records and clinical data collected during treatment were analyzed, and the Injury Severity Scale (ISS) was calculated. Patients were grouped into two cohorts based on the presence or absence of a physician during the prehospital phase. Data were analyzed with reference to survival by multivariable regression model. Specific inclusion criteria resulted in a sample of 67 patients. The groups were comparable with regard to age, gender, and injury etiology. Patients treated by prehospital physicians (group 1, n = 49) were more severely injured than patients treated by paramedics (group 2, n = 18) in terms of total burn surface area (%TBSA) (32% vs. 17%, p = 0.033), ISS (25 vs. 8, p < 0.000), and inhalation injuries (51% vs. 16%, p = 0.013), and presented with a higher pulse rate, lower systolic blood pressure, and lower median pH. Age, gender, %TBSA, and ISS were significantly associated with survival in both groups. Survival at 30 days was associated with age, gender, the amount of intravenous fluids (in liters) received during the first 24 hours, and the final %TBSA. Variables found to be independently associated by multivariable regression model with 30 day mortality were age, female gender, and final TBSA. We identified prehospital prognostic factors affecting patient outcomes. Based on the results from this study, our current EMS system is capable of identifying seriously injured burn patients who may benefit from physician attendance at the injury scene.

Towards more efficient burn care: Identifying factors associated with good quality of life post-burn

BACKGROUND

As minor burn patients constitute the vast majority of a developed nation case-mix, streamlining care for this group can promote efficiency from a service-wide perspective. This study tested the hypothesis that a predictive nomogram model that estimates likelihood of good long-term quality of life (QoL) post-burn is a valid way to optimise patient selection and risk management when applying a streamlined model of care.

METHOD

A sample of 224 burn patients managed by the Burn Service of Western Australia who provided both short and long-term outcomes was used to estimate the probability of achieving a good QoL defined as 150 out of a possible 160 points on the Burn Specific Health Scale-Brief (BSHS-B) at least six months from injury. A multivariate logistic regression analysis produced a predictive model provisioned as a nomogram for clinical application. A second, independent cohort of consecutive patients (n=106) was used to validate the predictive merit of the nomogram.

RESULTS AND DISCUSSION

Male gender (p=0.02), conservative management (p=0.03), upper limb burn (p=0.04) and high BSHS-B score within one month of burn (p<0.001) were significant predictors of good outcome at six months and beyond. A Receiver Operating Curve (ROC) analysis demonstrated excellent (90%) accuracy overall. At 80% probability of good outcome, the false positive risk was 14%. The nomogram was validated by running a second ROC analysis of the model in an independent cohort. The analysis confirmed high (86%) overall accuracy of the model, the risk of false positive was reduced to 10% at a lower (70%) probability. This affirms the stability of the nomogram model in different patient groups over time. An investigation of the effect of missing data on sample selection determined that a greater proportion of younger patients with smaller TBSA burns were excluded due to loss to follow up.

CONCLUSION

For clinicians managing comparable burn populations, the BSWA burns nomogram is an effective tool to assist the selection of patients to a streamlined care pathway with the aim of improving efficiency of service delivery.

Epidemiology and trends in severe burns in the Netherlands

INTRODUCTION

The aim of this study was to characterize the epidemiology of severe burns in the Netherlands, including trends in burn centre admissions, non burn centre admissions and differences by age.

METHODS

Patients with burn-related primary admission in a Dutch centre from 1995 to 2011 were included. Nationwide prospectively collected data were used from three separate historical databases and the uniform Dutch Burn Repository R3 (2009 onwards). General hospital data were derived from the National Hospital Discharge Register. Age and gender-adjusted rates were calculated by direct standardization, using the 2005 population as the reference standard.

RESULTS

The annual number of admitted patients increased from 430 in 1995 to 747 in 2011, incidence rates increased from 2.72 to 4.66 per 100,000. Incidence rates were high in young children, aged 0-4 years and doubled from 10.26 to 22.96 per 100,000. Incidence rates in persons from 5 up to 59 increased as well, in older adults (60 years and older) admission rates were stable. Overall burn centre mortality rate was 4.1%, and significantly decreased over time. There was a trend towards admissions of less extensive burns, median total burned surface area (TBSA) decreased from 8% to 4%. Length of stay and length of stay per percent TBSA decreased over time as well.

CONCLUSIONS

Data on 9031 patients admitted in a 17-year period showed an increasing incidence rate of burn-related burn centre admissions, with a decreasing TBSA and decreasing in-burn centre mortality. These data are important for prevention and establishment of required burn care capacity.

Epidemiology and referral patterns of burns admitted to the Burns Centre at Inkosi Albert Luthuli Central Hospital, Durban

RATIONALE

The epidemiology, referral patterns and outcome of patients admitted to a tertiary burns unit in southern Africa were reviewed.

MATERIALS AND METHODS

The charts of all patients with thermal injury presenting to the Burns Centre at Inkosi Albert Luthuli Central Hospital (IALCH) between 1 January 2008 and 31 December 2010 were reviewed. Information collected included age, gender, past medical history, cause of burn, size of burn, presence of inhalation injury, time before admission, time to excision, length of hospital stay, complications and mortality.

FINDINGS

Four hundred and sixty two patients were admitted, 296 (58%) children and 193 (42%) adults. The female-male ratio was 1:1.13. The mean total body surface area (TBSA) burned was 12% (interquartile range 8-25%) for children and 18% (interquartile range 10-35%) for adults. Common causes for the burns were in children: hot liquids (71%) and open flame (24%). Major causes in adults were: open fire (68%) and hot liquids (25%). Epilepsy was a contributing factor in 12.7%. Inhalation injury was seen in 13.6% of adults and 14.3% of children with a flame burn. Forty-four percent of referrals from general surgical units were for burns <30% in adults, and 30% for burns <10% in children. More than one in four patients was referred between 1 and 6 weeks post-injury. Overall mortality was 9.1% (5.7% in children and 15.1% in adults). Complications occurred in 21.6% of children and 36.7% in adults, the most common being lung complications such as ARDS and infection, severe sepsis, skin graft failure and contractures. The length of stay was 1 day/% TBSA burn for all burns in children and for burns between 10 and 49% in adults.

CONCLUSIONS

The epidemiology and outcome of severe burns referred to the Burns Centre at IALCH is similar to those in other units in Africa. The management and referral of burns patients by other hospitals are inappropriate in a significant number of patients.

Enhancing the clinical utility of the burn specific health scale-brief: not just for major burns

INTRODUCTION

Like many other Western burn services, the proportion of major to minor burns managed at Royal Perth Hospital (RPH) is in the order of 1:10. The Burn Specific Health Scale-Brief (BSHS-B) is an established measure of recovery after major burn, however its performance and validity in a population with a high volume of minor burns is uncertain. Utilizing the tool across burns of all sizes would be useful in service wide clinical practice.

AIM

This study was designed to examine the reliability and validity of the BSHS-B across a sample of mostly minor burn patients.

METHOD

BSHS-B scores of patients, obtained between January 2006 and February 2013 and stored on a secure hospital database were collated and analyzed Cronbach's alpha, factor analysis, logistic regression and longitudinal regression were used to examine reliability and validity of the BSHS-B.

RESULTS

Data from 927 burn patients (2031 surveys) with a mean % total burn surface area (TBSA) of 6.7 (SD 10.0) were available for analysis. The BSHS-B demonstrated excellent reliability with a Cronbach's alpha of 0.95. First and second order factor analyses reduced the 40 item scale to four domains: Work; Affect and Relations; Physical Function; Skin Involvement, as per the established construct. TBSA, length of stay and burn surgery all predicted burn specific health in the first three months of injury (p<0.001, p<0.001, p=0.03). BSHS-B whole scale and domain scores showed significant improvement over 24 months from burn (p<0.001).

DISCUSSION

The results from this study show that the structure and performance of the BSHS-B in a burn population consisting of 90% minor burns is consistent with that demonstrated in major burns.

CONCLUSION

The BSHS-B can be employed to track and predict recovery after burns of all sizes to assist the provision of targeted burn care.

The year in burns 2011

For 2011, approximately 1746 original research articles in burns were published in English in scientific journals. This article reviews those with the most potential impact on for burn therapeutics and outcomes according to the Editor of one of the major journals (Burns) and his colleague. As done previously, articles were found and divided into these topic areas: epidemiology of injury and burn prevention, wound and scar characterisation, acute care and critical care, inhalation injury, infection, psychological considerations, pain and itching management, rehabilitation and long-term outcomes, and burn reconstruction. Each selected article is mentioned briefly with editorial comment.
