What the COVID pandemic taught us about the management of pediatric minor trauma

The COVID-19 pandemic necessitated a change in our practice in the management of pediatric soft-tissue injuries. Patients were managed conservatively whenever possible. Our aim in this study was to see whether this more conservative approach adversely affected clinical, and patient-reported outcomes, including scarring. A prospective record of children presenting to the plastic surgery "Early Bird" clinic for pediatric trauma between 01.04.2020 and 30.06.2020 was kept. Electronic patient records were reviewed. An outpatient telephone clinic was scheduled for all patients. Parents were asked about complications and what they thought about the scar and to rate it as either: "poor," "satisfactory," "good," or "excellent." There were 240 patients, including 136 (57%) males and 104 (43%) females. The most frequent type of injury was a facial laceration in 123 patients (51.3%), followed by hand lacerations in 43 (17.9%), fingertip injuries in 31 (12.9%), and others. Ninety out of 240 (37.5%) were offered surgery. Follow-up times ranged from 17 to 20 months. Most parents (86.2%) were happy with the scarring and reported it as "good" or "excellent." The proportion rating the scar "excellent" or "good" was similar in the non-operated cohort (i.e., 85.5%) versus the operated cohort (88.5%) (p-value 0.16). The overall complication rate of patients seen during this time was 5.9%; 7.4% in the conservatively managed and 4.9% of those who went to the theater. Despite managing more wounds, including some dog bites, conservatively, patients and parents reported low complication rates and high levels of satisfaction with the final scarring.

Establishment of a core outcome set for burn care research: development and international consensus

Objective

To develop a core outcome set for international burn research.

Design

Development and international consensus, from April 2017 to November 2019.

Methods

Candidate outcomes were identified from systematic reviews and stakeholder interviews. Through a Delphi survey, international clinicians, researchers, and UK patients prioritised outcomes. Anonymised feedback aimed to achieve consensus. Pre-defined criteria for retaining outcomes were agreed. A consensus meeting with voting was held to finalise the core outcome set.

Results

Data source examination identified 1021 unique outcomes grouped into 88 candidate outcomes. Stakeholders in round 1 of the survey, included 668 health professionals from 77 countries (18% from low or low middle income countries) and 126 UK patients or carers. After round 1, one outcome was discarded, and 13 new outcomes added. After round 2, 69 items were discarded, leaving 31 outcomes for the consensus meeting. Outcome merging and voting, in two rounds, with prespecified thresholds agreed seven core outcomes: death, specified complications, ability to do daily tasks, wound healing, neuropathic pain and itch, psychological wellbeing, and return to school or work.

Conclusions

This core outcome set caters for global burn research, and future trials are recommended to include measures of these outcomes.

The development of the Delivery Assessment Tool (DAT) to facilitate quality improvement in burns services in low-middle income countries

Implementation science is a useful tool to consider ways in which we can introduce improvements to burn services in low-and-middle income countries (LMICs), where the majority of the burden of burn injury is now experienced. This paper outlines the development of the Delivery Assessment Tool (DAT), a method for facilitating quality improvement in burn services in LMICs. We used a participatory approach that ensured that local clinicians and experts were fully involved in piloting the tool. The DAT is based on internationally agreed operational standards for burn care service delivery and has undergone an iterative process of improvement and refinement through an initial three-year project in Nepal and Bangladesh. The DAT, a 50-item tool organised into 10 subsections, is used to assess a service through a participatory focus group discussion with a mixed, multidisciplinary team of staff working at the burn service, typically 6-10 participants. This usually lasts 2-3 h. The staff in the unit then select priority areas for quality improvement programmes that are within their control to achieve, which starts a cycle of audit and review. The final version of the tool was used in a further three-year project to evaluate 11 hospitals in Nepal and Bangladesh. Education and training are key components of this work; both were provided by Interburns as part of on-going support for the clinical teams. At the end of the project a>19% improvement in scores was demonstrated using the final version of the DAT in both Nepal and Bangladesh; this achievement is remarkable given the continued difficulties in service provision where patient numbers far outstrip the resources available to care for them. As a result of this work, we have made a digital version of the tool available free of charge.

Evaluation of high protein intake to improve clinical outcome and nutritional status for patients with burns: a systematic review

BACKGROUND AND AIM

Patients with severe burns undergo a local and systemic response to the injury. As part of this response the patient becomes hypermetabolic. Current guidelines advise high protein intakes to counteract the catabolic response to burns, but this appears to be based on minimal experimental evidence. Hence the aim of this review was to examine the evidence for improvements in nutritional status and clinical outcome with the administration of high protein intakes for patients with burns.

METHODS

Eight databases were searched for clinical trials with burn patients receiving two or more levels of protein intake at or above the level recommended for healthy individuals (0.75g/kg/d) and presenting results for at least one of the following pre-defined outcomes: nitrogen balance, length of stay, weight change, survival, physical therapy index, protein fractional synthetic rate, immunological measurements, bacteraemic days, systemic antibiotic days and net protein synthesis.

RESULTS

Six studies were included, 4 of which were randomized trials. All had major methodological limitations, in particular none was blinded. There was too much heterogeneity in study design, patient characteristics and the timing and magnitude of the interventions to justify formal meta-analysis. There was no reliable evidence of improvement in nitrogen balance, but there was some evidence of increased weight gain on higher protein diets. One small study reported an increase in survival and significant improvements in infection rates and some indicators of immune function in children. Length of stay was not significantly improved. There was weak evidence of an improvement in muscle strength and endurance but no significant increase in protein synthesis in muscle or skin, or net protein synthesis in the whole body.

CONCLUSION

There is currently only very weak evidence to justify administering high protein diets to patients following burns.

A comprehensive, integrated approach to quality improvement and capacity building in burn care and prevention in low and middle-income countries: An overview

•

Quality improvement requires a comprehensive integrated approach.

•

Clinical standards are a vital first step in improving outcomes for LMICs.

•

Capacity building needs a range of educational courses from basic to advanced.

•

Evaluation tools are needed to measure progress.

Consistent evidence has emerged over many years that the mortality and morbidity outcomes for burn patients in low and middle-income countries (LMICs) lag behind those in more resource rich countries. Interburns is a charity that was set up with the aim of working to reduce the disparity in the number of cases of burns as well as the outcomes for patients in LMICs. This paper provides an overview of a cyclical framework for quality improvement in burn care for use in LMICs that has been developed using an iterative process over the last 10 years. Each phase of the process is outlined together with a description of the tools used to conduct a gap analysis within the service, which is then used to frame a programme of capacity enhancement. Recent externally reviewed projects have demonstrated sustained improvement with the use of this comprehensive and integrated approach over a three-year cycle. This overview paper will be supported by further publications that present these results in detail.

Protocol for the development of a core indicator set for reporting burn wound infection in trials: ICon-B study

INTRODUCTION

Systematic reviews of high-quality randomised controlled trials are necessary to identify effective interventions to impact burn wound infection (BWI) outcomes. Evidence synthesis requires that BWI is reported in a consistent manner. Cochrane reviews investigating interventions for burns report that the indicators used to diagnose BWI are variable or not described, indicating a need to standardise reporting. BWI is complex and diagnosed by clinician judgement, informed by patient-reported symptoms, clinical signs, serum markers of inflammation and bacteria in the wound. Indicators for reporting BWI should be important for diagnosis, frequently observed in patients with BWI and assessed as part of routine healthcare. A minimum (core) set of indicators of BWI, reported consistently, will facilitate evidence synthesis and support clinical decision-making.

AIMS

The Infection Consensus in Burns study aims to identify a core indicator set for reporting the diagnosis of BWI in research studies.

METHODS

(1) Evidence review: a systematic review of indicators used in trials and observational studies reporting BWI outcomes to identify a long list of candidate indicators; (2) refinement of the long list into a smaller set of survey questions with an expert steering group; (3) a two-round Delphi survey with 100 multidisciplinary expert stakeholders, to achieve consensus on a short list of indicators; (4) a consensus meeting with expert stakeholders to agree on the BWI core indicator set.

ETHICS AND DISSEMINATION

Participants will be recruited through professional bodies, such that ethical approval from the National Health Service (NHS) Health Research Authority (HRA) is not needed. The core indicator set will be disseminated through peer-reviewed publication, co-production with journal editors, research funders and professional bodies, and presentation at national conferences.

Genetic influence on scar height and pliability after burn injury in individuals of European ancestry: A prospective cohort study

After similar extent of injury there is considerable variability in scarring between individuals, in part due to genetic factors. This study aimed to identify genetic variants associated with scar height and pliability after burn injury. An exome-wide array association study and gene pathway analysis were performed on a prospective cohort of 665 patients treated for burn injury. Outcomes were scar height (SH) and scar pliability (SP) sub-scores of the modified Vancouver Scar Scale (mVSS). DNA was genotyped using the Infinium^® HumanCoreExome-24 BeadChip. Associations between genetic variants (single nucleotide polymorphisms) and SH and SP were estimated using an additive genetic model adjusting for age, sex, number of surgical procedures and % total body surface area of burn in subjects of European ancestry. No individual genetic variants achieved the cut-off threshold of significance. Gene regions were analysed for spatially correlated single nucleotide polymorphisms and significant regions identified using comb-p software. This gene list was subject to gene pathway analysis to find which biological process terms were over-represented. Using this approach biological processes related to the nervous system and cell adhesion were the predominant gene pathways associated with both SH and SP. This study suggests genes associated with innervation may be important in scar fibrosis. Further studies using similar and larger datasets will be essential to validate these findings.

Neurosurgical transection of the breast: an unexpected extracranial complication of ventriculoperitoneal shunt insertion

Ventriculoperitoneal (VP) shunt placement is among the most common surgical procedures undertaken by neurosurgeons. Complications arising from the thoracic portion of the shunt are relatively rare in comparison with those of the intraventricular and peritoneal portions. Disruption of primary breast development following VP shunt placement has not previously been reported. The authors describe the case of a 15-year-old girl referred to the plastic surgery department with a significant right breast deformity and associated asymmetry following VP shunt placement performed during the neonatal period. The calcified shunt was excised and the breast deformity was corrected surgically through multiple scar tissue releases and restoration of the normal breast parenchymal anatomy via a minimally invasive approach, resulting in an excellent aesthetic outcome. This case highlights the potential for injury to occult breast tissue in pediatric patients undergoing VP shunt placement, which can impair subsequent cosmesis and quality of life.

A review of the evidence for threshold of burn injury

INTRODUCTION

Burn injury is common and depth is one measure of severity. Although the depth of burn injury is determined by many factors, the relationship between the temperature of the injurious agent and exposure duration, known as the time-temperature relationship, is widely accepted as one of the cornerstones of burn research. Moritz and Henriques first proposed this relationship in 1947 and their seminal work has been cited extensively. However, over the years, readers have misinterpreted their findings and incorporated misleading information about the time-temperature relationship into a wide range of industrial standards, burn prevention literature and medicolegal opinion.

AIM

The purpose of this paper is to present a critical review of the evidence that relates temperature and time to cell death and the depth of burn injury. These concepts are used by researchers, burn prevention strategists, burn care teams and child protection professionals involved in ascertaining how the mechanism of burning relates to the injury pattern and whether the injury is consistent with the history.

REVIEW METHODS

This review explores the robustness of the currently available evidence. The paper summarises the research from burn damage experimental work as well as bioheat transfer models and discusses the merits and limitations of these approaches.

REVIEW FINDINGS

There is broad agreement between in vitro and in vivo studies for superficial burns. There is clear evidence that the perception of pain in adult human skin occurs just above 43°C. When the basal layer of the epidermis reaches 44°C, burn injury occurs. For superficial dermal burns, the rate of tissue damage increases logarithmically with a linear increase in temperature. Beyond 70°C, rate of damage is so rapid that interpretation can be difficult. Depth of injury is also influenced by skin thickness, blood flow and cooling after injury. There is less clinical evidence for a time-temperature relationship for deep or subdermal burns. Bioheat transfer models are useful in research and becoming increasingly sophisticated but currently have limited practical use. Time-temperature relationships have not been established for burns in children's skin, although standards for domestic hot water suggest that the maximum temperature should be revised downward by 3-4°C to provide adequate burn protection for children.

CONCLUSION

Time-temperature relationships established for pain and superficial dermal burns in adult human skin have an extensive experimental modeling basis and reasonable clinical validation. However, time-temperature relationships for subdermal burns, full thickness burns and burn injury in children have limited clinical validation, being extrapolated from other data, and should be used with caution, particularly if presented during expert evidence.

Use of the Internet by burns patients, their families and friends

INTRODUCTION

The Internet has also become an increasingly important source of health-related information. However, with this exponential increase comes the problem that although the volume of information is huge, the quality, accuracy and completeness of the information are questionable, not only in the field of medicine. Previous studies of single medical conditions have suggested that web-based health information has limitations. The aim of this study was to evaluate Internet usage among burned patients and the people accompanying them to the outpatient clinic.

METHODS

A customised questionnaire was created and distributed to all patients and accompanying persons in the adult and paediatric burns clinics. This investigated computer usage, Internet access, usefulness of Internet search and topics searched.

RESULTS

Two hundred and ten people completed the questionnaire, a response rate of 83%. Sixty three percent of responders were patients, parents 21.9%, spouses 3.3%, siblings, children and friends the remaining 10.8%. Seventy seven percent of attendees had been injured within the last year, 11% between 1 and 5 years previously, and 12% more than 5 years previously. Seventy four percent had computer and Internet access. Twelve percent had performed a search. Topics searched included skin grafts, scarring and scar management treatments such as pressure garments, silicone gel and massage.

DISCUSSION

This study has shown that computer and Internet access is high, however a very small number actually used the Internet to access further medical information. Patients with longer standing injuries were more likely to access the Internet. Parents of burned children were more frequent Internet users. As more burn units develop their own web sites with information for patients and healthcare providers, it is important to inform patients, family members and friends that such a resource exists. By offering such a service patients are provided with accurate, reliable and easily accessible information which is appropriate to their needs.

The role of the Lumina intense pulsed light system in the treatment of port wine stains—a case controlled study

The pulsed dye laser has been the treatment of choice for port wine stains over the past 20 years. In the past 5 years there has been increasing discussion of the role of other light treatments, such as the intense pulsed light system in the treatment of port wine stains. These systems use high-energy lamps, which emit noncoherent broad-spectrum light. Cut off filters are applied depending on the treatment modality to limit the wavelengths emitted. We present the results of a 3-year prospective within patient controlled clinical trial using an intense pulsed light system called the Lumina, developed by Lynton Lasers of Cheshire, England. Our aims and objectives were to assess the effectiveness of the system in the treatment of port wine stains in a human model and to record the optimum treatment parameters and the incidence of side effects. Following ethical approval 12 subjects were enrolled into the trial. In order to meet the requirements of the local ethics committee these were all adults with port wine stains located in less visible areas of the body. The results showed that eight of the 12 subjects had some degree of fading of their port wine stain as measured on a percentage scoring system. Of the four who failed to show any response, all had pink port wine stains. It did seem the case that the darker the port wine stain, the better the fading seen. Furthermore, the more distal lesions tended to be less responsive than those situated closer to the head area. However, it is difficult to draw any definitive statistical conclusions due to the small number of patients in the trial.

Long-term behaviour of the free vascularised fibula following reconstruction of large bony defects

Thirty-two free vascularised fibula grafts performed at our unit have been assessed retrospectively with respect to success, bony union and percentage graft hypertrophy. Between 1981 and 1998, there were 21 males and 11 females (aged 8-61 years) with follow-up of 5 months to 14.6 years. The mean bony defect bridged was 12.0 cm (standard deviation 4.8; range 5.0-21.0 cm). Bony union and hypertrophy were assessed radiographically. Time to bony union was compared using the log-rank, Wilcoxon or likelihood ratio tests. Kaplan-Meier survival curves were constructed. Hypertrophy was compared with Wilcoxon's rank sum test.Three flaps failed. Seventy-four percent of patients healed primarily at a median time of 4.75 months; five patients required further surgery to heal by 18 months (interquartile range 14-20 months). Complication rate and donor site morbidity were low. The stress fracture rate was 21%. Ninety percent of patients regained a functional limb by 12 months.Hypertrophy was measured in 22 patients and ranged from 0 to 316% (median 71%; interquartile range 10-145%). Median hypertrophy in the lower limb was 76.5% (interquartile range 26.5-165%) compared to 33.5% in the upper limb (0-88%); p=0.16. Median hypertrophy in trauma cases was 80% (interquartile range 10-167%) compared to 70% in tumour cases (33-105%); p=0.62.Our findings confirm that the fibula responds physiologically to biomechanical loading. Our results compare well with other series and alternative reconstructive modalities. We conclude that the free fibula flap can provide excellent results in the salvage of limbs with large bony defects.

A comparison of three methods of repairing the hard palate

OBJECTIVE

To compare growth, speech, and nasal symmetry outcomes of three methods of hard palate repair.

PATIENTS

Consecutive available records of children born with unilateral bony complete cleft lip and palate over the period 1972 to 1992.

INTERVENTIONS

Identical management of lip, nose, alveolus, and soft palate. Hard palate repair by Cuthbert Veau (CV) from 1972 to 1981, von Langenbeck (vL) from 1982 to 1989, or medial Langenbeck (ML) from 1989 to 1991.

OUTCOME MEASURES

For growth: GOSLON yardstick or 5-year model index. For speech: articulation test. Nasal anemometry. For nasal symmetry: Coghlan computer-based assessment. All these measures were developed during the period of data collection but not for this project.

RESULTS

There was a strong trend toward more favorable anteroposterior maxillary growth with the change from CV to vL to ML techniques. This fell short of statistical significance because of the small sample size. There was a significant reduction in cleft-related articulation faults (p =.01) considered to be related to improved arch form. In the absence of improved rates of velopharyngeal insufficiency or nasal symmetry, increased surgical experience was discounted as a significant contribution to improved growth and articulation outcomes.

CONCLUSIONS

Reduced periosteal undermining and residual exposed palatal shelf from CV to vL to ML improved incisor relationships and articulation.
