Investigating the interrater reliability of a novel functional outcome measure for use in the burns intensive care unit: The Functional Assessment for Burns - Critical Care (FAB-CC).

INTRODUCTION: Intensive Care Unit Acquired Weakness challenges the clinical care of critically ill patients. Despite a surge in validated ICU functional outcome measures following the publication of Clinical Guideline 83 'Rehabilitation After Critical Illness' by the National Institute for Health and Care Excellence (2009), there are none composed specifically for use in the Burns ICU. We therefore developed and tested the inter-rater reliability of a burn specific novel functional outcome measure; The Functional Assessment for Burns-Critical Care (FAB-CC). OBJECTIVES: This research aimed to investigate the interrater reliability of the FAB-CC. METHODS: A quantitative reliability study assessed the ability of the FAB-CC to obtain accurate data when utilised by three separate raters (m=3) scoring the same clinical episodes (n=24). RESULTS: The Intraclass Correlation Coefficient (ICC) for the FAB-CC as a complete tool revealed excellent agreement (ICC 0.998; P<0.001, 95% confidence interval 0.996-0.999), with Cronbach's Alpha (α 0.999). Individual components of the FAB-CC displayed excellent agreement (ICC>0.983; P<0.001) with narrow 95% confidence intervals. CONCLUSIONS: The FAB-CC is a novel functional outcome measure that is reliable for use with critically ill burn patients. It has demonstrated real clinical utility in the identification and management of ICU-AW in this unique patient group.

The diagnosis and management of inhalation injury: An evidence based approach.

INTRODUCTION: Smoke inhalation injury (II) is an independent risk factor for mortality in burns and its management is inherently complex. We aim to make recommendations for best practice in managing II and its sequelae by reviewing all available current evidence in order to provide an evidence-based approach. METHODS: We conducted a systematic search of the Cochrane database and Embase using PRISMA guidelines with no patient population exclusion criteria. Published work was reviewed and evidence levels graded. RESULTS: We identified 521 abstracts for inclusion. Of the 84 articles identified for secondary review, 28 papers were excluded leaving 56 papers suitable for final inclusion. CONCLUSIONS: We are able to identify a number of strategies in both diagnosis and treatment of II that have support in the published literature, including the role of bronchoscopy, permissive hypercapnia, nebulized heparin and hydroxycobalamin. Other strategies have not been shown to be harmful, but their efficacy is also not firmly established, such as high frequency oscillatory ventilation and exogenous surfactant. Prophylactic antibiotics and corticosteroids are not recommended. In general, published evidence for II is mostly Level 3 or below, due to a noticeable lack of large-scale human studies. This represents a challenge for evidence-based burns practice as a whole.

One world one burn rehabilitation standard.

According to the World Health Organization (WHO) burns are a huge global health problem resulting in death and devastation to those who survive large burns as they are faced with significant functional limitations that prevent purposeful and productive living. Members of the International Society for Burn Injuries (ISBI) Rehabilitation Committee conducted a needs assessment survey in order to characterize how burn rehabilitation is implemented worldwide and how the international burn rehabilitation community can help improve burn rehabilitation in identified geographic locations which need assistance in rehabilitating burn survivors successfully. The results of this survey indicated that poor and in some cases resource limited environments (RLEs) around the world seem to lack the financial, educational and material resources to conduct burn rehabilitation successfully. It appears that there are vast discrepancies in the areas of education, training and capacity to conduct research to improve the care of burn survivors as evidenced by the variation in responses between the RLEs and developed countries around the globe. In some cases, the problem is not knowledge, skill and ability to practice burn rehabilitation, but rather having the resources to do so due to financial difficulties.

Percutaneous dilational and surgical tracheostomy in burn patients: incidence of complications and dysphagia.

The aim of this study is to evaluate the incidence of complications and dysphagia in relation to the timing of tracheostomy and tracheostomy technique in 49 consecutive adult burn patients. We analysed prospectively collected data. Bronchoscopy was used to diagnose tracheal stenosis and a modified Evans blue dye test was used to diagnose dysphagia. Eighteen patients received a percutaneous dilatational tracheostomy (PDT) and thirty-one patients received an open surgical tracheostomy (OST). Eight patients developed significant complications (16%) following tracheostomy, there is no difference in the incidence of complications; post op infection, stoma infection or tracheal stenosis between PDT and OST groups. Patients with full thickness neck burn who developed complications had a tracheostomy significantly earlier following autografting (p=0.05). Failed extubation is associated with dysphagia (p=0.02) whereas prolonged intubation and ventilation prior to tracheostomy independently predicts dysphagia (p=0.03). We conclude that there is no difference in the complication rates for PDT and OST in our burn patients. We recommend early closure of neck burns and tracheostomy through fully adherent autograft or at least 10 days after grafting to reduce stomal infections. For patients with no neck burn, we support early tracheostomy to reduce the likelihood of dysphagia.

Development and implementation of prospective outcome monitoring in a regional burns service using cumulative sum (CUSUM) techniques.

INTRODUCTION: Real-time monitoring of mortality in burns units has the potential to immediately mark when mortality rates are significantly higher or lower than predicted. Rapid feedback from targeted internal audit allows early intervention, to reinforce positive practices, and improve systems where outcomes are unsatisfactory. This is the first study to describe prospective use of cumulative sum (CUSUM) methodology in mortality monitoring outside of cardiac surgery. METHODS: An eight-year retrospective study of mortality was performed on all admissions to a regional burns intensive care unit in the UK. Risk-adjusted CUSUM charts, variable life adjusted displays (VLADs) and zeroed VLADs were produced to track mortality against that predicted by the Belgium burns score. The same techniques were implemented prospectively for one year (76 admissions) using the Osler modification of the Baux score for risk adjustment. RESULTS: Internal audit would have been triggered on nine occasions using zeroed VLAD monitoring in the retrospective study. The Belgium score overpredicts mortality in the elderly. Internal audit was triggered for better than predicted outcomes on two occasions in the prospective study. DISCUSSION: This study describes a successful design for an early-warning system to monitor outcomes in a burns intensive care setting.

The use of a frailty scoring system for burns in the elderly.

INTRODUCTION: Burn in the elderly has a high mortality. Scoring systems incorporating age, and/or co-morbidities have been developed to assist in predicting outcomes in this high risk group. Life expectancy has increased in the general population and within the elderly age group medical co morbidity, physiological response to injury and socioeconomic factors give rise to the concept of biological versus chronological age. For a given age, baseline pre morbid state can vary. It is more valid to consider biological rather than chronological age when calculating risk. The Canadian Study of Health and Aging (CSHA) clinical frailty scale, incorporating fitness, co-morbidities and level of dependence was used to analyse our elderly burn patients admitted to Burns ITU, their surgical management and one-year survival. METHOD: Data from patients with burns greater than 10% and aged over 65 years managed on the Burns ITU between 2005 and 2009 were obtained. A frailty score (1-7) was assigned to each patient based on the records of their admission assessment. 42 patients met the study criteria for analysis. 18 (42.9%) patients, with mean age 74.9 years (range 65-95 years) survived (S) their ITU stay and of these, 83.3% survived at 1 year. 24 (57.2%) patients, mean age 78.4 years (range 66-95 years) died (D) whilst on ITU. There was no significant difference between the two groups with regard to age, percentage burn (30% TBSA range 10-85%) (P>0.05 using T Test) or inhalational injury (p>0.05 using Z test). Using Mann-Whitney U test analysis, the frailty score between the two groups showed a significant difference at p=0.0001 (Mann-Whitney U test=78), median=3 (S) and median=5 (D). This suggests patients with better pre-morbid capacity, as evaluated by the frailty scoring system, were more likely to survive their burn insult and treatment. Significantly, more patients in the group that survived underwent surgical debridement (Mann-Whitney U test=111, p=0.02). CONCLUSION: Frailty scoring system appears to be a useful adjunct in predicting outcome in burns requiring admission to HDU/ITU in the senior population. The frailty score may predict which patients will benefit from surgery which also continues to be an important determinant of outcome in these patients.

Noninvasive Positive Pressure Ventilation in burns.

OBJECTIVE: Acute respiratory failure is a common complication of the severely burn-injured patient. Endotracheal intubation and mechanical ventilation is associated with a high rate of complications. Noninvasive Positive Pressure Ventilation (NIPPV) has been shown to be as effective as conventional ventilation in improving gas exchange and is associated with fewer complications with patients in acute hypercapnic and hypoxaemic respiratory failure. We report our experience with NIPPV in 30 burn patients. METHOD: The records of all burn patients from 1998 to 2000, where NIPPV was used as part of their management at the St. Andrew's Centre for Plastic Surgery and Burns, were reviewed. RESULTS: Mean age was 47.56 years (range 12-81). Nine patients were female. Mean burn size was 24.4% total body surface area (TBSA) (range 3-54). Inhalation injury was confirmed in eight cases. A positive diagnosis of pneumonia was made in 29 patients. The mean PaO(2)/FiO(2) ratio prior to institution of NIPPV was 28.98Kpa (range 8.75-52). Intermittent Positive Pressure Breathing (IPPB) was the most common ventilatory mode employed (25 patients) and the face mask was the most used interface (18 cases). Twenty-two patients (74%) avoided endotracheal intubation and their respiratory function continued to improve after NIPPV was discontinued. One patient (3%) died and seven patients (23%) were reintubated. Three out of the seven were electively reintubated for burns surgery. CONCLUSION: In burn-injured patients with acute respiratory failure, NIPPV appears to be effective in supporting respiratory function such that endotracheal intubation can be avoided in most cases.
