Hospital-acquired complications alter quality of life in adult burn survivors: Report from a burn model system

Early predictors of health-related quality of life outcomes at 12 months post-burn: ABLE study

There remains a paucity of evidence on the early predictors of long-term Health-Related Quality of Life (HRQoL) outcomes post-burn in hospitalised adults. The overall aim of this study was to identify the factors (personal, environmental, burn injury and burn treatment factors) that may predict long-term HRQoL outcomes among adult survivors of hospitalised burn injuries at 12 months post-burn. A total of 274 participants, aged 18 years or over, admitted to a single state-wide burn centre with a burn injury were recruited. Injury and burn treatment information were collected from medical records or the hospital database and surveys collected demographic and social data. HRQoL outcome data were collected at 3-, 6- and 12-months using the 12-Item Short Form Survey (SF-12 v1) and Burns Specific Health Scale-Brief (BSHS-B). Personal, environmental, burn injury and burn treatment factors were also recorded at baseline. Analyses were performed using linear and logistic regression. Among 274 participants, 71.5 % (N=196) remained enrolled in the study at 12 months post-burn. The majority of participants reported HRQoL outcomes comparable with population norms and statistically significant improvements in generic (SF-12 v1) and condition-specific (BSHS-B) outcomes over time. However, for participants with poor HRQoL outcomes at 12-months post-burn, Univariable predictors included longer hospital length of stay, unemployment at the time of injury, a diagnosed pre-injury mental health condition, inadequate pre-burn social support, intentional injury, recreational drug use pre-injury and female gender. The early multivariable predictors of insufficient HRQoL outcomes were female gender, a previously diagnosed mental health condition, unemployment, inadequate social support, intentional injury, and prolonged hospital length of stay. These results suggest potential factors that could be used to screen and burns patients for psychosocial intervention and long-term follow up.

Quality indicators for hospital burn care: a scoping review

BACKGROUND

Burn treatments are complex, and for this reason, a specialised multidisciplinary approach is recommended. Evaluating the quality of care provided to acute burn patients through quality indicators makes it possible to develop and implement measures aiming at better results. There is a lack of information on which indicators to evaluate care in burn patients. The purpose of this scoping review was to identify a list of quality indicators used to evaluate the quality of hospital care provided to acute burn patients and indicate possible aspects of care that do not have specific indicators in the literature.

METHOD

A comprehensive scoping review (PRISMA-ScR) was conducted in four databases (PubMed, Cochrane Library, Embase, and Lilacs/VHL) between July 25 and 30, 2022 and redone on October 6, 2022. Potentially relevant articles were evaluated for eligibility. General data and the identified quality indicators were collected for each included article. Each indicator was classified as a structure, process, or outcome indicator.

RESULTS

A total of 1548 studies were identified, 82 were included, and their reference lists were searched, adding 19 more publications. Thus, data were collected from 101 studies. This review identified eight structure quality indicators, 72 process indicators, and 19 outcome indicators listed and subdivided according to their objectives.

CONCLUSION

This study obtained a list of quality indicators already used to monitor and evaluate the hospital care of acute burn patients. These indicators may be useful for further research or implementation in quality improvement programs.

TRIAL REGISTRATION

Protocol was registered on the Open Science Framework platform on June 27, 2022 ( https://doi.org/10.17605/OSF.IO/NAW85 ).

Recovery of functional independence following major burn: A systematic review

BACKGROUND

Major burn injury, despite advancements in care and prevention, can have a profound impact on long-term morbidity, affecting quality of life and socioeconomic standing. We aim to explore factors predicting recovery of independence, the expected rate and time in majorly burned patients, and the measures of progress used.

METHOD

A systematic search of four databases (MEDLINE, EMBASE, COCHRANE, CINAHL) was conducted for studies reporting outcomes pertaining to physical ability indicative of independent function in adult (>15 y) cohorts who had suffered a major burn (>20% TBSA) up to 30 years after treatment in a developed specialised burn service. Data extracted included factors affecting rate of and time to achievement of function in five independence domains, as well as the outcome measures used.

RESULTS

21 eligible studies were included comprising 1298 major burns survivors with a combined mean age of 39.6 y and a mean TBSA of 25.8%. The most significant recurring factors impacting recovery of independent function were older age, female gender, burn severity, prolonged ICU and hospital admission, preceding mental health conditions, and post-acute psychological issues. Exercise-based rehabilitation conferred benefits on major burn patients even over 2 years following injury. Discharge to independent living from hospital occurred in 27% to 97% of patients, while reported return to work rates varied from 52% to 80%. Burns Specific Health Scale-Brief, Functional Independence Measure, and Physical Composite Score (SF-36) were the most widely used outcome scoring systems.

CONCLUSION

Major burn survivors have protracted recovery with potential for persistent chronic impairments, remaining consistently below baseline levels of function. Non-modifiable factors such as age and gender, and disease characteristics such as burn size with associated physical, physiological and psychosocial sequelae are contributory. Further research is required to explore achievement of specific milestones of major burn and polytrauma critical care patients, while early targeted rehabilitation addressing physical, psychological, and vocational needs has promising potential benefit.

Factors influence the dignity of burns patients: A cross-sectional study

BACKGROUND

There is a high incidence of burns in China and the sequelae of post-burn scar growth, disfigurement, and other body image disorders can cause serious psychological distress to burns patients, and negatively affecting the patient's dignity. However, there is limited knowledge relating to the dignity of burns patients.

AIM

To investigate the factors that affect dignity in burns patients.

DESIGN

Cross-sectional study.

PARTICIPANTS AND RESEARCH CONTEXT

We recruited 323 burn patients from the burn unit of a tertiary care hospital. The Patient Dignity Scale, Burn Specific Health Scale-Brief, Hospital Anxiety and Depression Scale were used to assess burn patients' dignity, quality of life, anxiety, and depression, respectively. 18 sociodemographic variables were included in the questionnaire.

ETHICAL CONSIDERATIONS

Before the data were collected, the study protocol was reviewed and approved by the Ethics Committee of the Guangzhou Red Cross Hospital of Jinan University (Reference: 2022-149-02) and all patients provided and signed informed consent forms.

FINDINGS

This study included 323 burns patients; of these, 26 (8%) had a mild loss of dignity, 94 (29.1%) had a moderate loss of dignity, 125 (38.7%) had a severe loss of dignity, and 78 (24.1%) had a very severe loss of dignity. The main factors that influence the loss of dignity in burns patients, including the department in which the patient was treated after their burns, gender, the clinical stage of the burn, quality-of-life, depression, resident medical insurance, the cause of the burn, and the burn site.

CONCLUSIONS

In most cases, the loss of dignity after burn injury is serious. Clinical health care professionals can provide personalized whole-life dignity care for patients by considering the factors that affect the dignity of burns patients, developing targeted dignity management programs, and implementing individualized interventions to maintain dignity, thus helping burns injury patients return to social life and work.

Use of Female External Urinary Catheters in a Burn Intensive Care Unit: Benefits and Challenges

BACKGROUND

Burn patients have a relatively high rate of indwelling Foley catheter use because of their need for complex fluid management and wound care. However, Foley catheter use is associated with risks, including urinary tract infection. For female patients, an external urinary catheter is an alternative.

OBJECTIVES

To evaluate the use of female external urinary catheters in a burn intensive care unit and to develop a standard protocol.

METHODS

This study involved female patients admitted to a burn intensive care unit from 2017 to 2020. An initiative to increase the use of female external urinary catheters was begun in 2019. A retrospective review of medical records was used to determine rates of indwelling and external catheter use and of catheter-associated urinary tract infection before and after implementation of the initiative.

RESULTS

Of 77 female burn patients admitted to the unit between 2019 and 2020, 56 (73%) required indwelling Foley catheterization, a significant decrease from 94% before the initiative (P = .002). The mean duration of indwelling Foley catheter use decreased significantly from 19.4 days to 10.47 days (P = .049). Female external urinary catheters were used in 21 patients (27%). No patients with female external urinary catheters contracted urinary tract infections, compared with 9 patients with indwelling Foley catheters.

CONCLUSION

The use of female external urinary catheters may help reduce the risk of urinary tract infection in female burn patients. Further research is needed to refine the protocol for use of these devices and determine their safety profile.

Statins block mammalian target of rapamycin pathway: a possible novel therapeutic strategy for inflammatory, malignant and neurodegenerative diseases

Inflammation plays a critical role in several diseases such as cancer, gastric, heart and nervous system diseases. Data suggest that the activation of mammalian target of rapamycin (mTOR) pathway in epithelial cells leads to inflammation. Statins, the inhibitors of the 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA), seem to be able to inhibit the mTOR. Statins are considered to have favorable effects on inflammatory diseases by reducing the complications caused by inflammation and by regulating the inflammatory process and cytokines secretion. This critical review collected data on this topic from clinical, in vivo and in vitro studies published between 1998 and June 2022 in English from databases including PubMed, Google Scholar, Scopus, and Cochrane libraries.

Suicide resilience, identity crisis and quality of life in burned adolescents

AIM

The aim of this study was to investigate the relationship between identity crisis and suicide resilience and quality of life in adolescents with burns in Iranian society.

DESIGN

A cross-sectional study.

METHODS

Four hundred thirty adolescents with burn in three hospitals were selected via convenience sampling. They completed questionnaires online. Data were analysed by SPSS software version 22.

RESULTS

Findings showed a strong and inverse correlation between identity crisis with suicide resilience (r = -.92, p < .001) and quality of life (r = -.87, p < .001). Variables of suicide resilience, being a child of a divorced family, cause of burns, extent of burn, financial situation, gender and age can predict 68.74% of the variance in identity crisis in these patients.

PATIENT OR PUBLIC CONTRIBUTION

Adolescents with burns suffer from an identity crisis, and although they report high resilience to suicide, they have a mediocre quality of life. Therefore, it is suggested that basic planning and extensive support be taken to improve physical and mental health, promote the quality of life and consequently reduce the identity crisis in these adolescents.

Burn Registries State of Affairs: A Scoping review

Registry science allows for the interpretation of disease-specific patient data from secondary databases. It can be utilized to understand disease and injury, answer research questions, and engender benchmarking of quality-of-care indicators. Numerous burn registries exist globally, however, their contributions to burn care have not been summarized. The objective of this study is to characterize the available literature on burn registries. The authors conducted a scoping review, having registered the protocol a priori. A thorough search of the English literature, including grey literature, was carried out. Publications of all study designs were eligible for inclusion provided they utilized, analyzed, and/or critiqued data from a burn registry. Three hundred twenty studies were included, encompassing 16 existing burn registries. The most frequently used registries for peer-reviewed publications were the American Burn Association Burn Registry, Burn Model System National Database, and the Burns Registry of Australia and New Zealand. The main limitations of existing registries are the inclusion of patients admitted to burn centers only, deficient capture of outpatient and long-term outcome data, lack of data standardization across registries, and the paucity of studies on burn prevention and quality improvement methodology. Registries are an invaluable source of information for research, delivery of care planning, and benchmarking of processes and outcomes. Efforts should be made to stimulate other jurisdictions to build burn registries and for existing registries to be improved through data linkage with administrative databases, and by standardizing one international minimum dataset, in order to maximize the potential of registry science in burn care.

Are burns a chronic condition? Examining patient reported outcomes up to 20 years after burn injury-A Burn Model System National Database investigation

BACKGROUND

People living with burn injury often face long-term physical and psychological sequelae associated with their injuries. Few studies have examined the impacts of burn injuries on long-term health and function, life satisfaction, and community integration beyond 5 years postinjury. The purpose of this study was to examine these outcomes up to 20 years after burn injury.

METHODS

Data from the Burn Model System National Longitudinal Database (1993-2020) were analyzed. Patient-reported outcome measures were collected at discharge (preinjury status recall) and 5 years, 10 years, 15 years, and 20 years after injury. Outcomes examined were the SF-12/VR-12 Physical Component Summary and Mental Component Summary, Satisfaction with Life Scale, and Community Integration Questionnaire. Trajectories were developed using linear mixed models with repeated measures of outcome scores over time, controlling for demographic and clinical variables.

RESULTS

The study population included 421 adult burn survivors with a mean age of 42.4 years. Lower Physical Component Summary scores (worse health) were associated with longer length of hospital stay, older age at injury and greater time since injury. Similarly, lower Mental Component Summary scores were associated with longer length of hospital stay, female sex, and greater time since injury. Satisfaction with Life Scale scores decrease negatively over time. Lower Community Integration Questionnaire scores were associated with burn size and Hispanic/Latino ethnicity.

CONCLUSION

Burn survivors' physical and mental health and satisfaction with life worsened over time up to 20 years after injury. Results strongly suggest that future studies should focus on long-term follow-up where clinical interventions may be necessary.

Disrupting mechanotransduction decreases fibrosis and contracture in split-thickness skin grafting

Burns and other traumatic injuries represent a substantial biomedical burden. The current standard of care for deep injuries is autologous split-thickness skin grafting (STSG), which frequently results in contractures, abnormal pigmentation, and loss of biomechanical function. Currently, there are no effective therapies that can prevent fibrosis and contracture after STSG. Here, we have developed a clinically relevant porcine model of STSG and comprehensively characterized porcine cell populations involved in healing with single-cell resolution. We identified an up-regulation of proinflammatory and mechanotransduction signaling pathways in standard STSGs. Blocking mechanotransduction with a small-molecule focal adhesion kinase (FAK) inhibitor promoted healing, reduced contracture, mitigated scar formation, restored collagen architecture, and ultimately improved graft biomechanical properties. Acute mechanotransduction blockade up-regulated myeloid CXCL10-mediated anti-inflammation with decreased CXCL14-mediated myeloid and fibroblast recruitment. At later time points, mechanical signaling shifted fibroblasts toward profibrotic differentiation fates, and disruption of mechanotransduction modulated mesenchymal fibroblast differentiation states to block those responses, instead driving fibroblasts toward proregenerative, adipogenic states similar to unwounded skin. We then confirmed these two diverging fibroblast transcriptional trajectories in human skin, human scar, and a three-dimensional organotypic model of human skin. Together, pharmacological blockade of mechanotransduction markedly improved large animal healing after STSG by promoting both early, anti-inflammatory and late, regenerative transcriptional programs, resulting in healed tissue similar to unwounded skin. FAK inhibition could therefore supplement the current standard of care for traumatic and burn injuries.

Using Pressure Mapping to Optimize Hospital-Acquired Pressure Injury Prevention Strategies in the Burn Intensive Care Unit

Although prior studies have demonstrated the utility of real-time pressure mapping devices in preventing pressure ulcers, there has been little investigation of their efficacy in burn intensive care unit (BICU) patients, who are at especially high risk for these hospital-acquired injuries. This study retrospectively reviewed clinical records of BICU patients to investigate the utility of pressure mapping data in determining the incidence, predictors, and associated costs of hospital-acquired pressure injuries (HAPIs). Of 122 patients, 57 (47%) were studied prior to implementation of pressure mapping and 65 (53%) were studied after implementation. The HAPI rate was 18% prior to implementation of pressure monitoring, which declined to 8% postimplementation (chi square: P = .10). HAPIs were less likely to be stage 3 or worse in the postimplementation cohort (P < .0001). On multivariable-adjusted regression accounting for known predictors of HAPIs in burn patients, having had at least 12 hours of sustained pressure loading in one area significantly increased odds of developing a pressure injury in that area (odds ratio 1.3, 95% CI 1.0-1.5, P = .04). Patients who developed HAPIs were significantly more likely to have had unsuccessful repositioning efforts in comparison to those who did not (P = .02). Finally, implementation of pressure mapping resulted in significant cost savings-$6750 (standard deviation: $1008) for HAPI-related care prior to implementation, vs $3800 (standard deviation: $923) after implementation, P = .008. In conclusion, the use of real-time pressure mapping decreased the morbidity and costs associated with HAPIs in BICU patients.

"Living Well" After Burn Injury: Using Case Reports to Illustrate Significant Contributions From the Burn Model System Research Program

The Burn Model System (BMS) program of research has been funded since 1993 by the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR). The overarching aim of this program is to improve outcomes and quality of life for people with burns in the areas of health and function, employment, and community living and participation. This review reports on BMS contributions that have affected the lives of individuals with a significant burn injury using case reports to associate BMS contributions with recovery. In January 2020, current BMS grantee researchers assessed peer-reviewed BMS publications from 1994 to 2020. Using case report methodology, contributions were linked to three individuals treated at one of the four Burn Model System institutions. With over 25 years of NIDILRR funding, unique BMS contributions to patient recovery were identified and categorized into one of several domains: treatment, assessment measures, sequelae, peer support, employment, and long-term functional outcomes. A second review for significant results of BMS research that add to the understanding of burn injury, pathophysiology, and recovery research was identified and categorized as injury recovery research. The case study participants featured in this review identified select NIDILRR research contributions as having direct, personal benefit to their recovery. The knowledge generation and clinical innovation that this research program has contributed to our collective understanding of recovery after burn injury is considerable. Using case study methodology with three adult burn survivors, we highlight the impact and individual significance of program findings and reinforce the recognition that the value of any clinical research must have relevance to the lives of the study population.

Infection in Elderly Burn Patients: What Do We Know?

Background: Infection is the greatest cause of mortality in burn patients. As our population ages, the need to care for elderly burn patients will increase, and with it our understanding of how infection affects older patients with burn injuries. This article presents a review of the available literature on the effect of aging on the physiologic response to burns, of the known effects of infection in the elder population, and of the contribution of underlying medical comorbidities to the outcomes for the elderly burn patient. The potential for more serious outcomes from multi-drug resistance in the elder population is also discussed. Methods: This article is a review of the available literature on infection in elderly burn patients. A literature search was performed for key words: elderly; geriatric; burn; infection; comorbidity; multi-drug resistance; central line; urinary tract infection; and burn sepsis. Relevant findings were included in each section. Results: Pre-existing conditions are common in the elderly and contribute to a higher rate of development of pneumonia, cellulitis, urinary tract infection, central line infections, and burn wound infections. Specific data pertaining to infections in the elderly burn population are scarce or confined to single-center reports. Conclusions: Because of the inherent susceptibility of the elder population to infection because of pre-existing medical conditions, immunosenescence, and potential exposure via frequent interaction with the medical system, vigilance must be maintained for preventing and treating infection in elderly burn patients. More research is needed to define the risks and extent of this increasingly important issue.

Burn survivors' perception of recovery after injury: A Northwest Regional Burn Model System investigation

INTRODUCTION

Previous reports suggest that many factors impact recovery from burn injury. To improve our understanding of these factors, we queried adult burn survivors using a mixed method design during the first year after injury.

METHODS

An anonymous, 2-page survey was developed and administered to adult burn survivors during routine outpatient clinic follow-up visits at a regional burn center. Participants rated issues of concern and their impacts on return to pre-burn activity levels. Both quantitative and qualitative data were obtained. Descriptive statistics were used to analyze quantitative data and thematic analysis was used to identify, analyze and report patterns from open-ended responses.

RESULTS

Over seven months in 2016, 187 patients completed the anonymous survey. Study participants were predominantly male, white, and non-Hispanic. Participants who had not yet returned to pre-burn function reported worse outcomes for all issues queried compared to those who had. Burn survivors from racial and ethnic minority groups reported greater difficulty with accessing medical care and information about their injury as well as higher levels of self-identified posttraumatic stress, issues related to appearance and concerns for loss of strength. Several themes and sub-themes were identified that had both negative and positive impact on early recovery. Such themes included: healing process, psychological recovery and emotional health, and community reintegration/employment.

CONCLUSIONS

Several themes from responses provided insight into challenges as well as key support systems during the first year of recovery after injury. Collectively, these findings can be used to direct clinical outpatient care, patient education and psychosocial support services.

Bone Marrow-Derived Mesenchymal Stem Cells Combined With Simvastatin Accelerates Burn Wound Healing by Activation of the Akt/mTOR Pathway

Burn wound healing is one of the most important problems in the field of medical science. Promising results have recently been reported by researchers who used bone marrow mesenchymal stem cells (BMSCs) to treat burn wounds. In this study, we investigated the effects of BMSC therapy in combination with simvastatin (SMV) on angiogenesis as well as on the activity of the Akt/mTOR signaling pathway during burn wound healing in rats. After creating second-degree burn wounds, 40 adult male Wistar rats were randomly divided into four treatment groups: the control, SMV, BMSCs, and the combination therapy group (BMSCs+SMV). Animals were killed 14 days after treatment initiation, and the wounds were removed for histological and molecular analyses. All in all, combination therapy produced better outcomes than individual therapy in terms of the wound closure area, epidermal regeneration level, collagen deposition intensity, and reepithelialization rate. In addition, the elevations of expression levels of Akt and mTOR genes, at both mRNA and protein levels, were more pronounced in the BMSCs+SMV group (P < .05, at least, for both qRT-PCR and western blot assessments). qRT-PCR findings also demonstrated that the wounds treated with the combination of BMSCs and SMV had the highest expression levels of CD31 and VEGF genes (P < .01 for all comparisons). These data suggest that the combined administration of BMSCs transplantation and topical SMV has a great potential in burn wound healing. According to the findings, the beneficial effects of the combination therapy are caused, at least in part, through stimulating Akt/mTOR signaling pathway.

Burn injury

Burn injuries are under-appreciated injuries that are associated with substantial morbidity and mortality. Burn injuries, particularly severe burns, are accompanied by an immune and inflammatory response, metabolic changes and distributive shock that can be challenging to manage and can lead to multiple organ failure. Of great importance is that the injury affects not only the physical health, but also the mental health and quality of life of the patient. Accordingly, patients with burn injury cannot be considered recovered when the wounds have healed; instead, burn injury leads to long-term profound alterations that must be addressed to optimize quality of life. Burn care providers are, therefore, faced with a plethora of challenges including acute and critical care management, long-term care and rehabilitation. The aim of this Primer is not only to give an overview and update about burn care, but also to raise awareness of the ongoing challenges and stigmata associated with burn injuries.
