Clinimetric Properties of the Steep Ramp Test to Assess Cardiorespiratory Fitness, Its Underlying Physiological Responses, and Its Current Applications: A Scoping Review

OBJECTIVE

Providing an overview of the clinimetric properties of the steep ramp test (SRT)-a short-term maximal exercise test-to assess cardiorespiratory fitness (CRF), describing its underlying physiological responses, and summarizing its applications in current clinical and research practice.

DATA SOURCES

MEDLINE (through PubMed), CINAHL Complete, Cochrane Library, EMBASE, and PsycINFO were searched for studies published up to July 2023, using keywords for SRT and CRF.

STUDY SELECTION

Eligible studies involved the SRT as research subject or measurement instrument and were available as full text articles in English or Dutch.

DATA EXTRACTION

Two independent assessors performed data extraction. Data addressing clinimetric properties, physiological responses, and applications of the SRT were tabulated.

DATA SYNTHESIS

In total, 370 studies were found, of which 39 were included in this study. In several healthy and patient populations, correlation coefficients between the work rate at peak exercise (WRpeak) attained at the SRT and oxygen uptake at peak exercise during cardiopulmonary exercise testing (CPET) ranged from .771-.958 (criterion validity). Repeated measurements showed intraclass correlation coefficients ranging from .908-.996 for WRpeak attained with the first and second SRT (test-retest reliability). Physiological parameters, like heart rate and minute ventilation at peak exercise, indicated that the SRT puts a lower burden on the cardiopulmonary system compared to CPET. The SRT is mostly used to assess CRF, among others as part of preoperative risk assessment, and to personalize interval training intensity.

CONCLUSIONS

The SRT is a practical short-term maximal exercise test that is valid for CRF assessment and to monitor changes in CRF over time in various healthy and patient populations. Its clinimetric properties and potential applications make the SRT of interest for a widespread implementation of CRF assessment in clinical and research practice and for personalizing training intensity and monitoring longitudinal changes in CRF.

The Role of Burn Centers in the Treatment of Necrotizing Soft-Tissue Infections: A Nationwide Dutch Study

Patients with extensive and complex wounds due to Necrotizing Soft-Tissue Infections (NSTI) may be referred to a burn center. This study describes the characteristics, outcomes, as well as diagnostic challenges of these patients. Patients admitted to three hospitals with a burn center for the treatment of NSTI in a 5-year period were included. Eighty patients (median age 54 years, 60% male) were identified, of whom 30 (38%) were referred by other centers, usually after survival of the initial septic phase. Those referred from other centers, compared to those primarily admitted to the study hospitals, were more likely to have group A streptococcal involvement (62% vs 35%, p = .02), larger wounds (median 7% vs 2% total body surface area, p < .001), and a longer length of stay (median 49 vs 22 days, p < .001). Despite a high incidence of septic shock (50%), the mortality rate was low (12%) for those primarily admitted. Approximately half (53%) of the patients were initially misdiagnosed upon presentation, which was associated with delay to first surgery (16 hours vs 4 hours, p < .001). Those initially misdiagnosed had more (severe) comorbidities, and less frequently reported pain or blue livid discoloration of the skin. This study underlines the burn centers' function as referral centers for extensively affected patients with NSTI. Besides the unique wound and reconstructive expertise, the low mortality rate indicates these centers provide adequate acute care as well. A major remaining challenge remains recognition of the disease upon presentation. Future studies in which factors associated with misdiagnosis are explored are needed.

Improvement of burn care by video interaction guidance

AIMS

To evaluate the effect of video interaction guidance on improving the nurse-child relationship during the wound care procedures. Additionally, determine whether the interactional behavior of nurses is related to pain and distress experienced by children.

METHODS

The interactional skills of seven nurses receiving video interaction guidance were compared with those of ten other nurses. The nurse-child interactions were video-taped during wound care procedures. Of the nurses receiving video interaction guidance, three wound dressing changes were videotaped before they received video interaction guidance and three after. The interaction between nurse and child was scored with the Nurse-child interaction taxonomy by two experienced raters. The COMFORT-B behavior scale was used to assess pain, and distress. All raters were blinded regarding video interaction guidance allocation and the sequence of tapes RESULTS: Five nurses in the intervention group (71 %) showed clinically relevant progress on the taxonomy while only four nurses (40 %) showed similar progress in the control group [p = .10]. A weak association was found between the nurses' interactions and the children's pain and distress [r = -.30, p = .002].

CONCLUSIONS

This is the first study to show that video interaction guidance can be used as a tool to train nurses to become more effective during patient encounters. Furthermore, nurses' interactional skills are positively associated with a child's pain and distress level.

Reliability and validity of a frailty assessment tool in specialized burn care, a retrospective multicentre cohort study

BACKGROUND

Frailty is a predictor of adverse outcomes in elderly patients. The Canadian Study of Health and Aging Clinical Frailty Scale (CFS) is an often-used frailty assessment instrument. However, the CFS's reliability and validity in patients with burn injuries are unknown. This study aimed to assess the CFS's inter-rater reliability and validity (predictive validity, known group validity and convergent validity) in patients with burn injuries treated to specialized burn care.

METHODS

A retrospective multicentre cohort study was conducted in all three Dutch burn centres. Patients aged ≥ 50 years with burn injuries, with a primary admission in 2015-2018, were included. Based on information in the electronic patient files, a research team member scored the CFS retrospectively. Inter-rater reliability was calculated using Krippendorff's α. Validity was assessed using logistic regression analysis. Patients with a CFS ≥ 5 were considered frail.

RESULTS

In total, 540 patients were included, with a mean age of 65.8 years (SD 11.5) and a Total Body Surface Area (TBSA) burned of 8.5%. The CFS was used to assess frailty in 540 patients and the reliability of the CFS was scored for 212 patients. Mean CFS was 3.4(SD 2.0). Inter-rater reliability was adequate, Krippendorff's α 0.69 (95%CI 0.62-0.74). A positive frailty screening was predictive of a non-home discharge location (OR 3.57, 95%CI 2.16-5.93), a higher in-hospital mortality rate (OR 1.06-8.77), and a higher mortality rate within 12 months after discharge (OR 4.61, 95%CI 1.99-10.65) after adjustment for age, TBSA, and inhalation injury. Frail patients were more likely to be older (for<70 vs. ≥70 years odds ratio 2.88, 95%CI 1.95-4.25) and their comorbidities were more severe (ASA ≥3 vs 1-2 OR 6.43, 95%CI 4.26-9.70) (known group validity). The CFS was significantly related (rSpearman=0.55) to the Dutch Safety Management System (DSMS) frailty screening, reflecting a fair-good correlation between the CFS and DSMS frailty screening outcomes.

CONCLUSION

The Clinical Frailty scale is reliable and has shown its validity, including its association with adverse outcomes in patients with burn injury admitted to specialized burn care. Early frailty assessment with the CFS must be considered, to optimize early recognition and treatment of frailty.

Fatigue in children and adolescents after burns: evaluating the problem using longitudinal data

PURPOSE

Describe prevalence and severity of fatigue in children and adolescents with burns during six months after hospital discharge, identify potential explanatory variables, and examine the relationship with exercise capacity.

MATERIALS AND METHODS

Fatigue was assessed using the Pediatric-Quality-of-Life-Inventory-Multidimensional-Fatigue-Scale (PedsQL-MFS) at discharge, and six weeks, three-, and six months after discharge. PedsQL-MFS scores ≥1 SD below the age-group specific non-burned reference mean were considered to signify fatigue.

RESULTS

Twenty-two children and adolescents (13 boys/9 girls, age 6-18 years, with burns covering 2-34% of total body surface area) were included. The prevalence of fatigue decreased from 65% (11/17) at discharge to 28% (5/18) six months after discharge. At group level, fatigue severity decreased over time, reaching healthy reference values from six weeks after discharge and beyond. At individual level, the course of fatigue severity varied widely. Fatigue severity at six months after discharge could not be predicted by age, sex, or burn severity (p = 0.51, p = 0.58, p = 0.95, respectively). The association with exercise capacity was weak (r = 0.062-0.538).

CONCLUSIONS

More than a quarter of pediatric burn patients reported fatigue six months after discharge. Further research in larger populations is required, including also the impact of burn-related fatigue on daily functioning and quality of life.Trial registration number: OND1353942Implications for rehabilitationFatigue should be recognized as a potential consequence of (pediatric) burns, even several months post burnFatigue should be assessed regularly after discharge in all children and adolescents with burns, as it seems not possible to predict its severity from age, sex, or burn severity characteristicsThe weak association between exercise capacity and self-reported fatigue suggests that burn-related fatigue is not simply a consequence of a reduced exercise capacity.

Virtual Reality as Pain Relief in Burn Care: A Pilot Randomized Controlled Trial on the Effectiveness on Pain During Multiple Dressing Changes

This pilot Randomized Controlled Trial (RCT) aimed to investigate the effectiveness of Virtual Reality (VR)-distraction on pain during multiple Wound Dressing Changes (WDCs). Furthermore, associations between demographic, clinical, and psychological factors and pain during WDC were determined. Participants were randomized to either the VR-condition or Care As Usual (CAU)-condition. Both groups received standard wound care and pain medication. The VR-group additionally received VR-distraction. The primary outcome measure was pain intensity (VAT 0-10). Secondary outcome measures were pain medication (Fentanyl spray and/or Piritramide) and satisfaction with WDC (VAT 0-10). Only 38 patients (VR-group: n = 21; CAU-group: n = 17) of the 128 intended patients were included during the study period due to several limitations (strict exclusion criteria and restrictions of the VR-equipment). No significant differences were found between both groups on pain intensity and medication. Both groups were also equally satisfied with WDC. Age showed a significant negative correlation with pain during WDC. In view of the small sample size, this study has restricted power and should be considered a pilot. Nevertheless, a RCT with between-subjects design across multiple WDCs was feasible and, given the speed of VR-developments, we expect larger, better powered RCTs to be possible in the near future, for which our experiences and recommendations are relevant.

Short-term and long-term increased mortality in elderly patients with burn injury: a national longitudinal cohort study

BACKGROUND

The population of elderly patients with burn injuries is growing. Insight into long-term mortality rates of elderly after burn injury and predictors affecting outcome is limited. This study aimed to provide this information.

METHODS

A multicentre observational retrospective cohort study was conducted in all three Dutch burn centres. Patients aged ≥65 years, admitted with burn injuries between 2009 and 2018, were included. Data were retrieved from electronic patient records and the Dutch Burn Repository R3. Mortality rates and standardized mortality ratios (SMRs) were calculated. Multivariable logistic regression was used to assess predictors for in-hospital mortality and mortality after discharge at 1 year and five-year. Survival analysis was used to assess predictors of five-year mortality.

RESULTS

In total, 682/771 admitted patients were discharged. One-year and five-year mortality rates were 8.1 and 23.4%. The SMRs were 1.9(95%CI 1.5-2.5) and 1.4(95%CI 1.2-1.6), respectively. The SMRs were highest in patients aged 75-80 years at 1 year (SMRs 2.7, 95%CI 1.82-3.87) and five-year in patients aged 65-74 years (SMRs 10.1, 95%CI 7.7-13.0). Independent predictors for mortality at 1 year after discharge were higher age (OR 1.1, 95%CI 1.0-1.1), severe comorbidity, (ASA-score ≥ 3) (OR 4.8, 95%CI 2.3-9.7), and a non-home discharge location (OR 2.0, 95%CI 1.1-3.8). The relative risk of dying up to five-year was increased by age (HR 1.1, 95%CI 1.0-1.1), severe comorbidity (HR 2.3, 95%CI 1.6-3.5), and non-home discharge location (HR 2.1, 95%CI 1.4-3.2).

CONCLUSION

Long-term mortality until five-year after burn injury was higher than the age and sex-matched general Dutch population, and predicted by higher age, severe comorbidity, and a non-home discharge destination. Next to pre-injury characteristics, potential long-lasting systemic consequences on biological mechanisms following burn injuries probably play a role in increased mortality. Decreased health status makes patients more prone to burn injuries, leading to early death.

Stromal vascular fraction-enriched fat grafting as treatment of adherent scars: study design of a non-randomized early phase trial

Background

In the last decades, autologous fat grafting has been used to treat adherent dermal scars. The observed regenerative and scar-reducing properties have been mainly ascribed to the tissue-derived stromal vascular fraction (tSVF) in adipose tissue. Adipose tissue’s components augment local angiogenesis and mitosis in resident tissue cells. Moreover, it promotes collagen remodeling. We hypothesize that tSVF potentiates fat grafting-based treatment of adherent scars. Therefore, this study aims to investigate the effect of tSVF-enriched fat grafting on scar pliability over a 12-month period.

Methods and design

A clinical multicenter non-randomized early phase trial will be conducted in two dedicated Dutch Burn Centers (Red Cross Hospital, Beverwijk, and Martini Hospital, Groningen). After informed consent, 46 patients (≥18 years) with adherent scars caused by burns, necrotic fasciitis, or degloving injury who have an indication for fat grafting will receive a sub-cicatricic tSVF-enriched fat graft. The primary outcome is the change in scar pliability measured by the Cutometer between pre- and 12 months post-grafting. Secondary outcomes are scar pliability (after 3 months), scar erythema, and melanin measured by the DSM II Colormeter; scar quality assessed by the patient and observer scales of the Patient and Observer Scar Assessment Scale (POSAS) 2.0; and histological analysis of scar biopsies (voluntary) and tSVF quality and composition. This study has been approved by the Dutch Central Committee for Clinical Research (CCMO), NL72094.000.20.

Conclusion

This study will test the clinical efficacy of tSVF-enriched fat grafting to treat dermal scars while the underlying working mechanism will be probed into too.

Hydrosurgical and conventional debridement of burns: randomized clinical trial

BACKGROUND

Tangential excision of burned tissue followed by skin grafting is the cornerstone of burn surgery. Hydrosurgery has become popular for tangential excision, with the hypothesis that enhanced preservation of vital dermal tissue reduces scarring. The aim of this trial was to compare scar quality after hydrosurgical versus conventional debridement before split-skin grafting.

METHODS

A double-blind randomized within-patient multicentre controlled trial was conducted in patients with burns that required split-skin grafting. One wound area was randomized to hydrosurgical debridement and the other to Weck knife debridement. The primary outcome was scar quality at 12 months, assessed with the observer part of the Patient and Observer Scar Assessment Scale (POSAS). Secondary outcomes included complications, scar quality, colour, pliability, and histological dermal preservation.

RESULTS

Some 137 patients were randomized. At 12 months, scars of the hydrosurgical debrided wounds had a lower POSAS observer total item score (mean 2.42 (95 per cent c.i. 2.26 to 2.59) versus 2.54 (95 per cent c.i. 2.36 to 2.72; P = 0.023)) and overall opinion score (mean 3.08 (95 per cent c.i. 2.88 to 3.28) versus 3.30 (95 per cent c.i. 3.09-3.51); P = 0.006). Patient-reported scar quality and pliability measurements were significantly better for the hydrosurgically debrided wounds. Complication rates did not differ between both treatments. Histologically, significantly more dermis was preserved with hydrosurgery (P < 0.001).

CONCLUSION

One year after surgery scar quality and pliability was better for hydrosurgically debrided burns, probably owing to enhanced histological preservation of dermis.

The degree of joint range of motion limitations after burn injuries during recovery

INTRODUCTION

The aim of this study was to determine the degree of ROM limitations of extremities, joints and planes of motion after burns and its prevalence over time.

METHOD

The database of a longitudinal multicenter cohort study in the Netherlands (2011-2012) was used. From patients with acute burns involving the neck, shoulder, elbow, wrist, hip, knee and ankle joints that had surgery, ROM of 17 planes of motion was assessed by goniometry at 3, 6 weeks, 3-6-9 and 12 months after burns and at discharge.

RESULTS

At 12 months after injury, 12 out of 17 planes of motion demonstrated persistent joint limitations. The five unlimited planes of motion were all of the lower extremity. The most severely limited joints at 12 months were the neck, ankle, wrist and shoulder. The lower extremity was more severely limited in the early phase of recovery whereas at 12 months the upper extremity was more severely limited.

CONCLUSION

The degree of ROM limitations and prevalence varied over time between extremities, joints and planes of motion. This study showed which joints and planes of motion should be watched specifically concerning the development of scar contracture.

Access to burn care in low-and middle-income countries: An assessment of timeliness, surgical capacity, and affordability in a regional referral hospital in Tanzania

This study investigates patients' access to surgical care for burns in a low-and-middle-income setting by studying timeliness, surgical capacity, and affordability. A survey was conducted in a regional referral hospital in Manyara, Tanzania. In total, 67 patients were included. To obtain information on burn victims in need of surgical care, irrespective of time lapsed from the burn injury, both patients with burn wounds and patients with contractures were included. Information provided by patients and/or caregivers was supplemented with data from patient files and interviews with hospital administration and physicians. In the burn wound group, 50 percent reached a facility within 24 hours after the injury. Referrals from other health facilities to the regional referral hospital were made within three weeks for 74 percent in this group. Of contracture patients, seventy four percent, had sought healthcare after the acute burn injury. Of the same group, only 4 percent had been treated with skin grafts beforehand, and 70 percent never received surgical care or a referral. Combined, both groups indicated that lack of trust, surgical capacity, and referral timeliness were important factors negatively impacting patient access to surgical care. Accounting for hospital fees indicated patients routinely exceeded the catastrophic expenditure threshold. It was determined that healthcare for burn victims is without financial risk protection. We recommend strengthening burn care and reconstructive surgical programs in similar settings, using a more comprehensive health systems approach to identify and address both medical and socio-economic factors that determine patient mortality and disability.

The development of burn scar contractures and impact on joint function, disability and quality of life in low- and middle-income countries: A prospective cohort study with one-year follow-up

OBJECTIVE

The aim of this study was to assess the development of burn scar contractures and their impact on joint function, disability and quality of life in a low-income country.

METHODS

Patients with severe burns were eligible. Passive range of motion (ROM) was assessed using lateral goniometry. To assess the development of contractures, the measured ROM was compared to the normal ROM. To determine joint function, the normal ROM was compared to the functional ROM. In addition, disability and quality of life (QoL) were assessed. Assessments were from admission up to 12 months after injury.

RESULTS

Thirty-six patients were enrolled, with a total of 124 affected joints. The follow-up rate was 83%. Limited ROM compared to normal ROM values was observed in 26/104 joints (25%) at 12 months. Limited functional ROM was observed in 55/115 joints (48%) at discharge and decreased to 22/98 joints (22%) at 12 months. Patients who had a contracture at 12 months reported more disability and lower QoL, compared to patients without a contracture (median disability 0.28 versus 0.17 (p = 0.01); QoL median 0.60 versus 0.76 (p = 0.001)). Significant predictors of developing joint contractures were patient delay and the percentage of TBSA deep burns.

CONCLUSION

The prevalence of burn scar contractures was high in a low-income country. The joints with burn scar contracture were frequently limited in function. Patients who developed a contracture reported significantly more disability and lower QoL. To limit the development of burn scar contractures, timely access to safe burn care should be improved in low-income countries.

Burn scar contracture release surgery effectively improves functional range of motion, disability and quality of life: A pre/post cohort study with long-term follow-up in a Low- and Middle-Income Country

OBJECTIVE

Burn scar contractures limit range of motion (ROM) of joints and have substantial impact on disability and the quality of life (QoL) of patients, particularly in a Low- and Middle-Income Country (LMIC) setting. Studies on the long-term outcome are lacking globally; this study describes the long-term impact of contracture release surgery performed in an LMIC.

METHODS

This is a pre-post cohort study, conducted in a referral hospital in Tanzania. Patients who underwent burn scar contracture release surgery in 2017-2018 were eligible. ROM (goniometry), disability (WHODAS 2.0) and QoL (EQ-5D) were assessed. The ROM data were compared to the ROM that is required to perform activities of daily living without compensation, i.e. functional ROM. Assessments were performed preoperatively and at 1, 3, 6 and 12 months postoperatively.

RESULTS

In total, 44 patients underwent surgery on 115 affected joints. At 12 months, the follow-up rate was 86%. The mean preoperative ROM was 37.3% of functional ROM (SD 31.2). This improved up to 108.7% at 12 months postoperatively (SD 42.0, p < 0.001). Disability-free survival improved from 55% preoperatively to 97% at 12 months (p < 0.001) postoperatively. QoL improved from 0.69 preoperatively, to 0.93 (max 1.0) at 12 months postoperatively (p < 0.001). Patients who regained functional ROM in all affected joints reported significantly less disability (p < 0.001) and higher QoL (p < 0.001) compared to patients without functional ROM.

CONCLUSIONS

Contracture release surgery performed in an LMIC significantly improved functional ROM, disability and QoL. Results showed that regaining a functional joint is associated with less disability and higher QoL.

The impact of early information concerning the surgical operations on anxiety in patients with burns

AIMS

Stress has been linked to poor coping with health-related issues, poor adaptation, a decrease of quality of life, poor recovery and poor wound healing. Therefore, it is important to address patients' uncertainty and feelings of anxiety. The aim of this study was to examine the effect of providing early treatment information based on an LDI-scan to patients with burns on their feelings of anxiety.

DESIGN

An observational prospective pre-test post-test study.

METHODS

Patients with intermediate burns (n = 59) admitted to our burn centre in 2016 were evaluated for anxiety using a visual analogue scale (VAS-A) before and after an LDI-scan was made. Two groups were compared: a group that heard whether surgery would or would not be recommended for wound closure (certain group) versus a group that heard to wait and see whether an operation was determined to be helpful (uncertain group).

RESULTS

Before the LDI-scan was made, both groups showed clinically high levels of anxiety (median VAS scores above 5). After the information gathered with the LDI was discussed with the patient, anxiety dropped significantly (median VAS below 3; p = .001). No significant differences between the groups were observed (p > .05).

CONCLUSION

In contrast to other studies, anxiety was significantly reduced in all our study groups after information was shared. Early communication of knowledge by health care professionals is important regardless whether it includes treatment uncertainty.

Questionnaires to Assess Facilitators and Barriers of Early Mobilization in Critically Ill Patients; Which One to Choose? A Systematic Review

Implementing and performing early mobilization is a complex process requiring multidisciplinary input and cooperation. To gain insight in its facilitators and barriers, various surveys have been developed. A systematic review was conducted, to identify the psychometric properties, feasibility and suitability of questionnaires to assess facilitators and barriers of early mobilization in critically ill patients. Data were extracted regarding a.o. definition of early mobilization, development, psychometric properties, content and themes, question format. The search identified 537 publications of which 13 unique questionnaires were included. The questionnaires showed wide variation in extensiveness of development. Only six questionnaires actually assessed validity and reliability. Which questionnaire to choose depends on the aim of its use, required level of detail and specifics of the ICU, though three questionnaires were recommended as their definition of early mobilization covered a broad range of activities, including nursing related mobility activities. International consensus on what constitutes early mobilization is desirable.

Topical treatment for facial burns

BACKGROUND

Burn injuries are an important health problem. They occur frequently in the head and neck region. The face is the area central to a person's identity that provides our most expressive means of communication. Topical interventions are currently the cornerstone of treatment of burns to the face.

OBJECTIVES

To assess the effects of topical interventions on wound healing in people with facial burns of any depth.

SEARCH METHODS

In December 2019 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that evaluated the effects of topical treatment for facial burns were eligible for inclusion in this review.

DATA COLLECTION AND ANALYSIS

Two review authors independently performed study selection, data extraction, risk of bias assessment and GRADE assessment of the certainty of the evidence.

MAIN RESULTS

In this first update, we included 12 RCTs, comprising 507 participants. Most trials included adults admitted to specialised burn centres after recent burn injuries. Topical agents included antimicrobial agents (silver sulphadiazine (SSD), Aquacel-Ag, cerium-sulphadiazine, gentamicin cream, mafenide acetate cream, bacitracin), non-antimicrobial agents (Moist Exposed Burn Ointment (MEBO), saline-soaked dressings, skin substitutes (including bioengineered skin substitute (TransCyte), allograft, and xenograft (porcine Xenoderm), and miscellaneous treatments (growth hormone therapy, recombinant human granulocyte-macrophage colony-stimulating factor hydrogel (rhGMCS)), enzymatic debridement, and cream with Helix Aspersa extract). Almost all the evidence included in this review was assessed as low or very low-certainty, often because of high risk of bias due to unclear randomisation procedures (i.e. sequence generation and allocation concealment); lack of blinding of participants, providers and sometimes outcome assessors; and imprecision resulting from few participants, low event rates or both, often in single studies. Topical antimicrobial agents versus topical non-antimicrobial agents There is moderate-certainty evidence that there is probably little or no difference between antimicrobial agents and non-antimicrobial agents (SSD and MEBO) in time to complete wound healing (hazard ratio (HR) 0.84 (95% confidence interval (CI) 0.78 to 1.85, 1 study, 39 participants). Topical antimicrobial agents may make little or no difference to the proportion of wounds completely healed compared with topical non-antimicrobial agents (comparison SSD and MEBO, risk ratio (RR) 0.94, 95% CI 0.68 to 1.29; 1 study, 39 participants; low-certainty evidence). We are uncertain whether there is a difference in wound infection (comparison topical antimicrobial agent (Aquacel-Ag) and MEBO; RR 0.38, 95% CI 0.12 to 1.21; 1 study, 40 participants; very low-certainty evidence). No trials reported change in wound surface area over time or partial wound healing. There is low-certainty evidence for the secondary outcomes scar quality and patient satisfaction. Two studies assessed pain but it was incompletely reported. Topical antimicrobial agents versus other topical antimicrobial agents It is uncertain whether topical antimicrobial agents make any difference in effects as the evidence is low to very low-certainty. For primary outcomes, there is low-certainty evidence for time to partial (i.e. greater than 90%) wound healing (comparison SSD versus cerium SSD: mean difference (MD) -7.10 days, 95% CI -16.43 to 2.23; 1 study, 142 participants). There is very low-certainty evidence regarding whether topical antimicrobial agents make a difference to wound infection (RR 0.73, 95% CI 0.46 to 1.17; 1 study, 15 participants). There is low to very low-certainty evidence for the proportion of facial burns requiring surgery, pain, scar quality, adverse effects and length of hospital stay. Skin substitutes versus topical antimicrobial agents There is low-certainty evidence that a skin substitute may slightly reduce time to partial (i.e. greater than 90%) wound healing, compared with a non-specified antibacterial agent (MD -6.00 days, 95% CI -8.69 to -3.31; 1 study, 34 participants). We are uncertain whether skin substitutes in general make any other difference in effects as the evidence is very low certainty. Outcomes included wound infection, pain, scar quality, adverse effects of treatment and length of hospital stay. Single studies showed contrasting low-certainty evidence. A bioengineered skin substitute may slightly reduce procedural pain (MD -4.00, 95% CI -5.05 to -2.95; 34 participants) and background pain (MD -2.00, 95% CI -3.05 to -0.95; 34 participants) compared with an unspecified antimicrobial agent. In contrast, a biological dressing (porcine Xenoderm) might slightly increase pain in superficial burns (MD 1.20, 95% CI 0.65 to 1.75; 15 participants (30 wounds)) as well as deep partial thickness burns (MD 3.00, 95% CI 2.34 to 3.66; 10 participants (20 wounds)), compared with antimicrobial agents (Physiotulle Ag (Coloplast)). Miscellaneous treatments versus miscellaneous treatments Single studies show low to very low-certainty effects of interventions. Low-certainty evidence shows that MEBO may slightly reduce time to complete wound healing compared with saline soaked dressing (MD -1.7 days, 95% CI -3.32 to -0.08; 40 participants). In addition, a cream containing Helix Aspersa may slightly increase the proportion of wounds completely healed at 14 days compared with MEBO (RR 4.77, 95% CI 1.87 to 12.15; 43 participants). We are uncertain whether any miscellaneous treatment in the included studies makes a difference in effects for the outcomes wound infection, scar quality, pain and patient satisfaction as the evidence is low to very low-certainty.

AUTHORS' CONCLUSIONS

There is mainly low to very low-certainty evidence on the effects of any topical intervention on wound healing in people with facial burns. The number of RCTs in burn care is growing, but the body of evidence is still hampered due to an insufficient number of studies that follow appropriate evidence-based standards of conducting and reporting RCTs.

A taxonomy to assess the interaction between nurses and children: Development and reliability

AIMS AND OBJECTIVES

The aim of this study was to develop a valid and reliable instrument to assess the nurse-child interaction during medical or nursing interventions.

BACKGROUND

Communication is an important competency for the professional practice of nurses and physicians. The nurse-patient relationship is fundamental for high-quality care. It has been suggested that if nurses have more skills to interact with children, care will be less distressing and less painful for the children.

DESIGN

A qualitative observational psychometric study; the GRRAS checklist was used.

METHODS

In-depth video-analyses, taxonomy development (19 videos) and testing it is psychometric properties (10 videos). Three observers micro-analysed video recordings of experienced nurses changing children's wound dressing in a specialised Burn Centre.

RESULTS

The nurse-child interaction taxonomy (NCIT) was developed to observe and score the interactional behaviour between nurse and child. The taxonomy has three main patterns: being considerate, attuning oneself, and procedural interventions, subdivided in eight dimensions. These dimensions contain 16 elements that can be observed and scored on a 7-point scale. Intra-rater, inter-rater reliability and agreement were good.

CONCLUSIONS

This study shows that interaction between nurses and children can be assessed reliably with the NCIT by an experienced observer or alternatively, scoring by two observers is recommended.

RELEVANCE TO CLINICAL PRACTICE

The development of the taxonomy is an important step to find evidence for the best way for nurses to interact with children during nursing interventions or medical events and as such, ultimately, contributes to providing the best care possible.

Doxepin cream is not effective in reducing itch in burn scar patients: A multicenter triple-blind randomized clinical crossover trial

OBJECTIVE

To evaluate the effect of doxepin hydrochloride 5% cream on reducing pruritus in burn scar patients compared to a placebo cream.

METHOD

We conducted a multicenter triple-blind randomized clinical placebo-controlled crossover trial in which burn patients ≥18 years with an itch intensity ≥3 on a Visual Analogue Scale (VAS) were randomized between a doxepin-placebo or placebo-doxepin treatment protocol. Patients used each cream during two weeks with a wash-out period of one week in between. Primary outcome was change in itch intensity in two weeks' time using the VAS. Secondary outcome included the impact of itch (Burn Itch Questionnaire). Other parameters were the use of hydrating cream, silicon treatment, pressure garments, and other antipruritic medication.

RESULTS

Twenty-seven patients were included. The change in itch intensity (VAS) was not different during the doxepin and placebo period (p=0.994); neither the doxepin cream nor placebo cream reduced itch intensity. However, based on the Burn Itch Questionnaire, we observed a statistically significant decrease in itch intensity and improvement in impact scores in both treatment groups, but no difference in the degree of reduction between the groups.

CONCLUSION

Doxepin cream was not effective in reducing pruritus in our burn patient study population.

Joint flexibility problems and the impact of its operationalisation

BACKGROUND

Dissatisfaction is being voiced with the generally used way joint flexibility problems are defined (operationalised), i.e. as a range of motion (ROM) one or more degrees lower than normative ROM of healthy subjects. Other, specifically more function-related operationalisations have been proposed. The current study evaluated the effect of applying different operationalisations of joint flexibility problems on its prevalence.

METHOD

ROM data of 95 joints affected by burns of 23 children were used, and data on 18 functional activities (Burn Outcome Questionnaire (BOQ)). Five methods were used to operationalise joint flexibility problems: (1) ROM below normative ROM, (2) ROM below normative ROM minus 1SD, (3) ROM below normative ROM minus 2SD, (4) ROM below functional ROM, and (5) a score of 2 or more on the Likert Scale (BOQ).

RESULTS

Prevalence of joint flexibility problems on a group level ranged from 13 to 100% depending on the operationalisation used. Per joint and movement direction, prevalence ranged from 40% to 100% (Method 1) and 0% to 80% (Methods 2-4). 18% of the children received '2' on the Likert Scale (Method 5).

CONCLUSION

The operationalisation of joint flexibility problems substantially influences prevalence, both on group and joint level. Changing to a function-related operationalisation seems valuable; however, international consensus is required regarding its adoption.

Predictability of exercise capacity following pediatric burns: a preliminary investigation

PURPOSE

Describe the course of exercise capacity in pediatric burn patients during the initial 6 months after hospital discharge, and examine whether its recovery can be predicted from burn characteristics, sociodemographic characteristics, and/or prior assessment.

MATERIALS AND METHODS

Exercise capacity was assessed at discharge, and 6 weeks, 3 months, and 6 months after discharge using the Steep Ramp Test (SRT).

RESULTS

Twenty-four pediatric patients with burns affecting 0.1-34% of total body surface area were included. At group level, exercise capacity was low at discharge and did not reach healthy reference values within 6 months, despite significant improvement over time. At individual level, the course of exercise capacity varied widely. Six months after discharge, 48% of participants scored more than one standard deviation below healthy age- and sex-specific reference values. SRT outcomes at 6 weeks and 3 months were the best predictors of exercise capacity 6 months after discharge, explaining, respectively, 76% and 93% of variance.

CONCLUSIONS

Forty-eight percent of participants did not achieve healthy reference values of exercise capacity and were therefore considered "at risk" for diminished functioning. Our preliminary conclusion that early assessment of exercise capacity with the SRT can timely identify those patients, needs to be strengthened by further research.IMPLICATIONS FOR REHABILITATIONPediatric burns can be considered as a chronic medical condition because of the lifelong consequences.Exercise capacity is reduced following- even minor -pediatric burns.Recovery patterns vary widely: some pediatric burn patients achieve healthy levels of exercise capacity without specific intervention, while others do not.The Steep Ramp Test can be used to assess exercise capacity, identifying those "at risk" for adverse outcomes at an early stage.Patients "at risk" should be encouraged to play sports and adopt an active lifestyle.

Long-term scar quality after hydrosurgical versus conventional debridement of deep dermal burns (HyCon trial): study protocol for a randomized controlled trial

Background

Deep dermal burns require tangential excision of non-viable tissue and skin grafting to improve wound healing and burn-scar quality. Tangential excision is conventionally performed with a knife, but during the last decade hydrosurgery has become popular as a new tool for tangential excision. Hydrosurgery is generally thought to be a more precise and controlled manner of burn debridement leading to preservation of viable tissue and, therefore, better scar quality. Although scar quality is considered to be one of the most important outcomes in burn surgery today, no randomized controlled study has compared the effect of these two common treatment modalities with scar quality as a primary outcome. The aim of this study is, therefore, to compare long-term scar quality after hydrosurgical versus conventional tangential excision in deep dermal burns.

Methods/design

A multicenter, randomized, intra-patient, controlled trial will be conducted in the Dutch burn centers of Rotterdam, Beverwijk, and Groningen. All patients with deep dermal burns that require excision and grafting are eligible. Exclusion criteria are: a burn wound < 50 cm², total body surface area (TBSA) burned > 30%, full-thickness burns, chemical or electrical burns, infected wounds (clinical symptoms in combination with positive wound swabs), insufficient knowledge of the Dutch or English language, patients that are unlikely to comply with requirements of the study protocol and follow-up, and patients who are (temporarily) incompetent because of sedation and/or intubation. A total of 137 patients will be included. Comparable wound areas A and B will be appointed, randomized and either excised conventionally with a knife or with the hydrosurgery system. The primary outcome is scar quality measured by the observer score of the Patient and Observer Scar Assessment Scale (POSAS); a subjective scar-assessment instrument, consisting of two separate six-item scales (observer and patient) that are both scored on a 10-point rating scale.

Discussion

This study will contribute to the optimal surgical treatment of patients with deep dermal burn wounds.

Physical activity and sedentary behavior following pediatric burns - a preliminary investigation using objective activity monitoring

Background

Adequate levels of regular physical activity (PA) are crucial for health and well-being. Pediatric burn injuries can have major physiological consequences in both the short and long term. The question is whether these consequences affect post burn PA levels. This study therefore aimed to describe PA and sedentary behavior (SB) in children and adolescents 1–5 years after burn injury.

Methods

Daily PA and SB were monitored in 20 children and adolescents (12 boys and 8 girls, aged 6–17 years, with burns covering 10–37% of total body surface area, 1–5 years post burn) for 1 week using the ActiGraph GTX3+ accelerometer. Activity counts were categorized into SB, light PA, moderate PA, vigorous PA, moderate-to-vigorous PA (MVPA), and total PA. Outcomes were compared with non-burned reference values and PA levels recommended by the World Health Organization (WHO).

Results

The participants spent about 5.1 h per day on total PA and 7.4 h on SB. Most of the active time (~ 83%) was categorized as light PA. Thirty-five percent of the group, especially the young boys, spent on average ≥ 60 min on MVPA per day. The boys, although with large interindividual differences, spent more time on MVPA than the girls (p < .005). Older age was associated with less PA time, while more time was spent sedentary. No trends were found indicating an effect of burn characteristics, time post burn, or length of hospital stay, and no differences were found with non-burned peers.

Conclusion

Duration and intensity of PA and SB in children and adolescents 1–5 years after burn injury were similar to non-burned peers. However, only 35% of the group met the WHO physical activity recommendation. Given the increased long term risk for physical conditions following pediatric burns, physical activity should be encouraged in this vulnerable population.

[Determining depth of burns using laser Doppler imaging]

Early accurate assessment of burn depth is important to determine the optimal treatment of burns (conservative versus surgery). Laser Doppler imaging (LDI) is a technique that allows accurate measurement of burn depth by measuring dermal perfusion. Although it has been demonstrated that LDI led to faster decisions as to whether or not to operate, this has not lead to shorter wound healing time or cost savings in Dutch burn care. LDI is used in all Dutch burn centres. In case of doubt about the depth of a burn in primary or secondary care, referral to a burn centre is advisable.

Extensive colonization with carbapenemase-producing microorganisms in Romanian burn patients: infectious consequences from the Colectiv fire disaster

Health care of severe burn patients is highly specialized and may require international patient transfer. Burn patients have an increased risk of developing infections. Patients that have been hospitalized in countries where carbapenemase-producing microorganisms (CPMO) are endemic may develop infections that are difficult to treat. In addition, there is a risk on outbreaks with CPMOs in burn centers. This study underlines that burn patients may extensively be colonized with CPMOs, and it provides best practice recommendations regarding clinical microbiology and infection control. We evaluated CPMO-carriage and wound colonization in a burn patient initially treated in Romania, and transported to the Netherlands. The sequence types and acquired beta-lactamase genes of highly-resistant microorganisms were derived from next generation sequencing data. Next, we searched literature for reports on CPMOs in burn patients. Five different carbapenemase-producing isolates were cultured: two unrelated OXA-48-producing Klebsiella pneumoniae isolates, OXA-23-producing Acinetobacter baumanii, OXA-48-producing Enterobacter cloacae, and NDM-1-producing Providencia stuartii. Also, multi-drug resistant Pseudomonas aeruginosa isolates were detected. Among the sampling sites, there was high variety in CPMOs. We found 46 reports on CPMOs in burn patients. We listed the epidemiology of CPMOs by country of initial treatment, and summarized recommendations for care of these patients based on these reports and our study.

Indications and Predictors for Reconstructive Surgery After Hand Burns

PURPOSE

The objective of this study was to analyze the prevalence, indications, and type of reconstructive surgery and predictors of the outcomes of reconstructive surgery after hand burns.

METHODS

A retrospective cohort study was conducted that included all patients admitted with acute hand burns in the Dutch burn centers from January 1998 through December 2002. The details of reconstruction including frequency, timing, indication, and techniques were collected over a 10-year follow-up period.

RESULTS

Hand burns were seen in 42% (n = 562 of 1,334) of all patients admitted with acute burns. Reconstructive surgery during the 10-year follow-up period was required in 15%. Contractures, especially of the first web space and little finger, were the most frequent indications for reconstructive surgery. Web spaces 1 to 3 and the little finger were the location most frequently operated on. The most frequently performed surgical technique was release of the contractures and the use of a random flap. Eighty percent of the reconstructive surgery patients required more than 1 reconstructive procedure, most often within 2 years of the initial injury. Secondary operations at the same location were required in 12%. In 40% of the patients, the first reconstructive surgery was performed within the first postburn year. Significant independent factors related to the need for reconstructive hand surgery were a larger area of full-thickness burns and surgical treatment of the hand during the acute phase.

CONCLUSIONS

Reconstructive surgery was required in 15% of patients who sustained hand burns. The majority of the patients requiring reconstructive surgery of the hand needed 2 or more operations to correct the contractures of the hand. Contractures of the little finger and first web space were the locations most frequently operated on. Patients with more extensive burns and who required hand surgery during the acute phase were more likely to need reconstructive surgery.

Return to work after specialised burn care: A two-year prospective follow-up study of the prevalence, predictors and related costs

BACKGROUND

Burn injuries may cause long-term disability and work absence, and therefore result in high healthcare and productivity costs. Up to now, detailed information on return to work (RTW) and productivity costs after burns is lacking.

AIMS

The aim of this study was to accurately assess RTW after burn injuries, to identify predictors of absenteeism and to calculate healthcare and productivity costs from a societal perspective.

METHODS

A prospective cohort study was conducted in the burn centre of Rotterdam, the Netherlands, including all admitted working-age patients from 1 August 2011 to 31 July 2012. At 3, 12 and 24 months post-burn, patients were sent a questionnaire: including the Work and Medical Consumption questionnaire for the assessment of work absence and medical consumption and the EQ-5D-3L plus a cognitive dimension to assess post-burn and pre-burn quality of life (QOL). Cost analyses were from a societal perspective according the micro-costing method and the friction cost method was applied for the calculation of productivity loss. Univariate logistic regression was used to identify predictors of absenteeism at three months.

RESULTS

A total of 104 patients were included in the study with a mean total body surface area (TBSA) burned of 8% (median 4%). 66 respondents were pre-employed, at 3 months 70% was back at work, at 12 months 92% and 8% had not returned to work at time of final follow-up at 24 months. Predictors of absenteeism at 3 months were: TBSA, length of stay, ICU-admission and surgery. Mean costs related to loss in productivity were €11.916 [95% CI 8.930-14.902] and accounted for 30% of total costs in pre-employed respondents in the first two years.

CONCLUSION

This two-year follow-up study demonstrates that burn injuries cause substantial and prolonged productivity loss amongst burn survivors with mixed burn severity. This absenteeism contributes to already high societal costs of burn injuries. Predictors of absenteeism found in this study were primarily fixed patient and treatment related factors, future studies should focus on modifiable factors, in order to improve RTW outcomes. Also, more attention in the rehabilitation trajectory is needed to optimally support RTW in burn survivors.

Effect and mechanism of hydrocortisone on organ function in patients with severe burns

INTRODUCTION

In patients with severe burns, resuscitation with large volumes of fluid is needed, partly because of an increase in capillary leakage. Corticosteroids might be beneficial by diminishing capillary leakage. This study aimed to assess in severely burned nonseptic patients whether hydrocortisone (HC) improved outcome and diminished capillary leakage.

METHODS

Retrospective analyses of a prospectively collected database were performed, including 39 patients (age 52 [35-62] years, 72% male). Patients were divided based on HC therapy. First, in patients in whom HC was started late, that is when deteriorating (late; 5-12 days postburn) data before and after start of HC were compared. Second, patients in whom HC was started day 0 or 1 postburn (upfront; within 48 hours) were compared with patients who did not receive HC (control). Outcome was assessed as organ dysfunction by Denver Multiple Organ Failure (MOF) score and Sequential Organ Failure Assessment (SOFA) score. As markers for capillary leakage and hydration state, proteinuria, B-type natriuretic peptide (BNP), and fluid administration were assessed. Follow-up was 20 days postburn. Possible adverse effects including mortality were recorded. Repeated measurement regression analyses were performed using MLwiN.

RESULTS

In the late group, Denver MOF and SOFA scores significantly decreased after HC (P<.001). Proteinuria tended to decrease (P=.13), BNP increased on the days HC was used (P<.001), and amounts of fluids diminished (P<.001). In the upfront vs control group, Denver MOF and SOFA scores (P<.001) decreased more quickly. Proteinuria (P=.006) and administered fluids decreased more rapidly (P<.001). Mortality rate, numbers of positive blood cultures, incidence of pneumonia, and graft loss were similar in all groups.

CONCLUSIONS

Hydrocortisone treatment in severe burned patients without sepsis might improve organ dysfunction possibly because of a reduction in capillary leakage, as reflected by a decrease of proteinuria, an increase of BNP, and diminished fluid resuscitation volumes.

Long-term scar quality in burns with three distinct healing potentials: A multicenter prospective cohort study

The laser Doppler imager is used in cases of indeterminate burn depth to accurately predict wound healing time at an early stage. The laser Doppler imager classifies burns into three estimated healing potentials as follows: high, <14 days; intermediate, 14-21 days; and low, >21 days. At this time, the relationship between these healing potentials and long-term scar quality is unknown. The objective of this study was to determine the long-term scar quality of burns with three distinct healing potentials. The secondary objectives were to compare treatment strategies in intermediate wounds, to study the effect of the timing of surgery on low healing potential wounds and to identify predictors of reduced scar quality. Hence, in a prospective cohort study, scar quality was determined in patients whose burns were assessed with laser Doppler imaging. Scar Quality was assessed with objective and subjective measurement tools, including overall scar quality (Patient and Observer Scar Assessment Scale) as a primary outcome and color and elasticity parameters. A total of 141 patients (>19 months postburn) with 216 scars were included. Wounds with high and intermediate healing potential did not significantly differ regarding scar quality. Wounds with a low healing potential had a significantly lower scar quality. Analysis of 76 surgically treated low healing potential wounds showed no significant differences in the primary outcome regarding the timing of surgery (≤14 days vs. >14). Predictors of reduced long-term scar quality were darker skin type and multiple surgeries. In conclusion, scar quality was strongly related to the healing potential category. Scar quality was very similar in high and intermediate healing potential wounds. No positive effects were found on scar quality or on healing time in surgically treated wounds with intermediate healing potential, advocating a conservative approach. Further studies should focus on the optimal timing of surgery in low healing potential wounds.

Economic burden of burn injuries in the Netherlands: A 3 months follow-up study

INTRODUCTION

Burn care has rapidly improved in the past decades. However, healthcare innovations can be expensive, demanding careful choices on their implementation. Obtaining knowledge on the extent of the costs of burn injuries is an essential first step for economic evaluations within burn care. The objective of this study was to determine the economic burden of patients with burns admitted to a burn centre and to identify important cost categories until 3 months post-burn.

PATIENTS AND METHODS

A prospective cohort study was conducted in the burn centre of Maasstad Hospital Rotterdam, the Netherlands, including all patients with acute burn related injuries from August 2011 until July 2012. Total costs were calculated from a societal perspective, until 3 months post injury. Subgroup analyses were performed to examine whether the mean total costs per patient differed by age, aetiology or percentage total body surface area (TBSA) burned.

RESULTS

In our population, with a mean burn size of 8%, mean total costs were €26,540 per patient varying from €742 to €235,557. Most important cost categories were burn centre days (62%), surgical interventions (5%) and work absence (20%). Flame burns were significantly more costly than other types of burns, adult patients were significantly more costly than children and adolescents and a higher percentage TBSA burned also corresponded to significantly higher costs.

DISCUSSION AND CONCLUSION

Mean total costs of burn care in the first 3 months post injury were estimated at €26,540 and depended on age, aetiology and TBSA. Mean total costs in our population probably apply to other high-income countries as well, although we should realise that patients with burn injuries are diverse and represent a broad range of total costs. To reduce costs of burn care, future intervention studies should focus on a timely wound healing, reducing length of stay and enabling an early return to work.

Cost study of dermal substitutes and topical negative pressure in the surgical treatment of burns

BACKGROUND

A recently performed randomised controlled trial investigated the clinical effectiveness of dermal substitutes (DS) and split skin grafts (SSG) in combination with topical negative pressure (TNP) in the surgical treatment of burn wounds. In the current study, medical and non-medical costs were investigated, to comprehensively assess the benefits of this new treatment.

METHODS

The primary outcome was mean total costs of the four treatment strategies: SSG with or without DS, and with or without TNP. Costs were studied from a societal perspective. Findings were evaluated in light of the clinical effects on scar elasticity.

RESULTS

Eighty-six patients were included. Twelve months post-operatively, highest elasticity was measured in scars treated with DS and TNP (p=0.027). The initial cost price of treatment with DS and TNP was €2912 compared to treatment with SSG alone €1703 (p<0.001). However, mean total costs per patient did not differ significantly between groups (range €29097-€43774).

DISCUSSION

Costs of the interventional treatment contributed maximal 7% to the total costs and total costs varied widely within and between groups, but were not significantly different. Therefore, in the selection of the most optimal type of surgical intervention, cost considerations should not play an important role.

Cost-effectiveness of laser Doppler imaging in burn care in the Netherlands

Background

Early accurate assessment of burn depth is important to determine the optimal treatment of burns. The method most used to determine burn depth is clinical assessment, which is the least expensive, but not the most accurate.

Laser Doppler imaging (LDI) is a technique with which a more accurate (>95%) estimate of burn depth can be made by measuring the dermal perfusion. The actual effect on therapeutic decisions, clinical outcomes and the costs of the introduction of this device, however, are unknown. Before we decide to implement LDI in Dutch burn care, a study on the effectiveness and cost-effectiveness of LDI is necessary.

Methods/design

A multicenter randomised controlled trial will be conducted in the Dutch burn centres: Beverwijk, Groningen and Rotterdam. All patients treated as outpatient or admitted to a burn centre within 5 days post burn, with burns of indeterminate depth (burns not obviously superficial or full thickness) and a total body surface area burned of ≤ 20% are eligible. A total of 200 patients will be included. Burn depth will be diagnosed by both clinical assessment and laser Doppler imaging between 2–5 days post burn in all patients. Subsequently, patients are randomly divided in two groups: ‘new diagnostic strategy’ versus ‘current diagnostic strategy’. The results of the LDI-scan will only be provided to the treating clinician in the ‘new diagnostic strategy’ group. The main endpoint is the effect of LDI on wound healing time.

In addition we measure: a) the effect of LDI on other patient outcomes (quality of life, scar quality), b) the effect of LDI on diagnostic and therapeutic decisions, and c) the effect of LDI on total (medical and non-medical) costs and cost-effectiveness.

Discussion

This trial will contribute to our current knowledge on the use of LDI in burn care and will provide evidence on its cost-effectiveness.

Topical treatment for facial burns

BACKGROUND

Burn injuries are an important health problem. They occur frequently in the head and neck region - the area central to a person's identity, that provides our most expressive means of communication. Topical interventions are currently the cornerstone of treatment of partial-thickness burns to the face.

OBJECTIVES

To assess the effects of topical interventions on wound healing in people with facial burns of any depth.

SEARCH METHODS

We searched the Cochrane Wounds Group Specialised Register (searched 12 November 2012); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 10); Ovid MEDLINE (1950 to November Week 1 2012); Ovid MEDLINE - In-process & Other Non-Indexed Citations (searched November 12, 2012); Ovid EMBASE (1980 to 2012 Week 45); and EBSCO CINAHL (1982 to 9 November 2012) for relevant trials. We did not apply date or language restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that evaluated the effects of topical treatment for facial burns were eligible for inclusion in this review.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed and included the references identified by the search strategy. Included trials were assessed using a risk of bias form, and data were extracted using a standardised data extraction sheet. For dichotomous and continuous outcomes, we calculated risk ratios and mean differences, respectively, both with 95% confidence intervals (CI).

MAIN RESULTS

We included five RCTs, comprising a total of 119 participants. Two studies compared two different antimicrobial agents and three compared a biological or bioengineered skin substitute with an antimicrobial agent. All studies had small sample sizes and were at high risk of bias. Heterogeneity of interventions and outcomes prevented pooling of data. In three studies time to complete wound healing was significantly shorter for those using a skin substitute than for those using an antibacterial agent, but the quality of the evidence was low. Pain was significantly reduced with the use of skin substitutes in both studies that reported this outcome in all groups, range mean differences -2.00 (95% CI -3.82 to -0.18) to -4.00 (95% CI -5.05 to -2.95) on a 10-point scale.

AUTHORS' CONCLUSIONS

There is insufficient high quality research and evidence to enable conclusions to be drawn about the effects of topical interventions on wound healing in people with facial burns.

How disabling are pediatric burns? Functional independence in Dutch pediatric patients with burns

Although the attention for functional outcomes after burn injury has grown over the past decades, little is known about functional independence in performing activities of daily living in children after burn injury. Therefore, in this prospective cohort study functional independence was measured by burn care professionals with the WeeFIM(®) instrument in 119 pediatric patients with burns (age: 6 months-16 years; 58.8% boys) in the Netherlands. In order to identify whether functional independence was affected, participants' total scores on the WeeFIM(®) instrument were compared to American norm values. Of the participants assessed at 2 weeks post burn (n = 117), 3 months post burn (n = 68) and/or 6 months post burn (n = 38), 22, 9 and 9 participants showed affected performance, respectively. Improvements in WeeFIM(®) total scores for the total study population between 2 weeks and 6 months post burn were significant (Wilcoxon T = 2.5; p<.001, effect size = -0.59). Individual improvements were found to be significant for 30.3% of the assessed participants between 2 weeks and 3 months post burn, and for 12.1% between 3 and 6 months post burn. This study is unique in providing data on functional independence for this large and special population. However, a proportion of participants were lost to follow-up and the use of the WeeFIM(®) instrument in this specific population and setting has its limitations. To conclude, burn injury impacts functional independence in children, yet the vast majority of Dutch pediatric patients with burns returns to functional independence typical for age within 6 months post burn.

Design of a cross-sectional study on physical fitness and physical activity in children and adolescents after burn injury

Background

Burn injuries have a major impact on the patient’s physical and psychological functioning. The consequences can, especially in pediatric burns, persist long after the injury. A decrease in physical fitness seems logical as people survive burn injuries after an often extensive period of decreased activity and an increased demand of proteins leading to catabolism, especially of muscle mass. However, knowledge on the possibly affected levels of physical fitness in children and adolescents after burn injury is limited and pertains only to children with major burns. The current multidimensional study aims to determine the level of physical fitness, the level of physical activity, health-related quality of life and perceived fatigue in children after a burn injury. Furthermore, interrelations between those levels will be explored, as well as associations with burn characteristics.

Methods/design

Children and adolescents in the age range of 6 up to and including 18 years are invited to participate in this cross-sectional descriptive study if they have been admitted to one of the three Dutch burn centers between 6 months and 5 years ago with a burn injury involving at least 10% of the total body surface area and/or were hospitalized ≥ 6 weeks. Physical fitness assessments will take place in a mobile exercise lab. Quantitative measures of cardiorespiratory endurance, muscular strength, body composition and flexibility will be obtained. Outcomes will be compared with Dutch reference values. Physical activity, health-related quality of life and fatigue will be assessed using accelerometry and age-specific questionnaires.

Discussion

The findings of the current study will contribute to a better understanding of the long-term consequences of burn injury in children and adolescents after burns. The results can guide rehabilitation to facilitate a timely and optimal physical recovery.

Trial registration

The study is registered in the National Academic Research and Collaborations Information System of the Netherlands (OND1348800).

Clinical effectiveness of dermal substitution in burns by topical negative pressure: a multicenter randomized controlled trial

Previous research has shown clinical effectiveness of dermal substitution; however, in burn wounds, only limited effect has been shown. A problem in burn wounds is the reduced take of the autograft, when the substitute and graft are applied in one procedure. Recently, application of topical negative pressure (TNP) was shown to improve graft take. The aim of this study was to investigate if application of a dermal substitute in combination with TNP improves scar quality after burns. In a four-armed multicenter randomized controlled trial, a split-skin graft with or without a dermal substitute and with or without TNP was compared in patients with deep dermal or full-thickness burns requiring skin transplantation. Graft take and rate of wound epithelialization were evaluated. Three and 12 months postoperatively, scar parameters were measured. The results of 86 patients showed that graft take and epithelialization did not reveal significant differences. Significantly fewer wounds in the TNP group showed postoperative contamination, compared to other groups. Highest elasticity was measured in scars treated with the substitute and TNP, which was significantly better compared to scars treated with the substitute alone. Concluding, this randomized controlled trial shows the effectiveness of dermal substitution combined with TNP in burns, based on extensive wound and scar measurements.

Accuracy of burn size assessment prior to arrival in Dutch burn centres and its consequences in children: a nationwide evaluation

BACKGROUND

Total body surface area (TBSA) burned, expressed as percentage is one of the most important aspects of the initial care of a burn victim. It determines whether transfer to a burn centre is necessary as well as the need for, and amount of, intravenous fluid resuscitation. Numerous studies, however, have highlighted inaccuracies in TBSA assessment. Therefore, the differences in burn size estimates between referrers and burn centre's in children and its consequences in terms of transfer and intravenous fluid resuscitation were investigated.

METHODS

This study involved two time periods from January 2002 until March 2004 and January 2007 until August 2008. All referred children admitted to a Dutch Burn centre within 24h post burn were eligible. Data were obtained from patient records retrospectively and in part prospectively.

RESULTS

A total of 323 and 299 children were included in periods 1 and 2, respectively. Referring physicians overestimated burn size with a factor two (mean difference: 6% TBSA ± 5.5). About one in five children was referred to a burn centre without fulfilling the criteria for referral with regard to burn size (assessed by burn specialists) special localisation or inhalation trauma. Proportions of children receiving intravenous fluid resuscitation regardless of indication increased from 33% to 49% (p<0.01). The received volumes tended to be higher than necessary.

CONCLUSIONS

Referring physicians overestimate burn size in children admitted to Dutch burn centres. This has little negative consequences, however, in terms of unindicated transfers to a burn centre or unnecessary fluid resuscitation.

[Determining burn depth: clinical assessment and laser Doppler imaging]

Early accurate determination of burn depth is important to determine the optimal treatment of burns. The method most used to determine burn depth is clinical assessment. This is a cheap method, but not the most accurate. Laser Doppler imaging (LDI) is a technique with which a more accurate (>95%) estimate of burn depth can be made by measuring the dermal perfusion. It is hypothesised that the introduction of LDI will lead to quicker decisions as to whether or not to operate, possibly leading to a shorter length of hospital stay and lower medical costs. To test this hypothesis, a multicentre randomized controlled trial is presently being conducted in the Dutch burn centres.

A review on static splinting therapy to prevent burn scar contracture: do clinical and experimental data warrant its clinical application?

BACKGROUND

Static splinting therapy is widely considered an essential part in burn rehabilitation to prevent scar contractures in the early phase of wound healing. However, scar contractures are still a common complication. In this article we review the information concerning the incidence of scar contracture, the effectiveness of static splinting therapy in preventing scar contractures, and specifically focus on the - possible - working mechanism of static-splinting, i.e. mechanical load, at the cellular and molecular level of the healing burn wound.

METHOD

A literature search was done including Pubmed, Cochrane library, CINAHL and PEDRO.

RESULTS

Incidence of scar contracture in patients with burns varied from 5% to 40%. No strong evidence for the effectiveness of static splinting therapy in preventing scar contracture was found, whereas in vitro and animal studies demonstrated that mechanical tension will stimulate the myofibroblast activity, resulting in the synthesis of new extracellular matrix and the maintenance of their contractile activity.

CONCLUSION

The effect of mechanical tension on the wound healing process suggests that static splinting therapy may counteract its own purpose. This review stresses the need for randomised controlled clinical trials to establish if static splinting to prevent contractures is a well-considered intervention or just wishful thinking.

Increased B-type natriuretic peptide and decreased proteinuria might reflect decreased capillary leakage and is associated with a better outcome in patients with severe burns

Introduction

It is difficult to adjust fluid balance adequately in patients with severe burns due to various physical changes. B-type natriuretic peptide (BNP) is emerging as a potential marker of hydration state. Proteinuria is used as a predictor of outcome in severe illness and might correlate to systemic capillary leakage. This study investigates whether combining BNP and proteinuria can be used as a guide for individualized resuscitation and as a predictor of outcome in patients with severe burns.

Methods

From 2006 to 2009, 38 consecutive patients (age 47 ± 15 years, 74% male) with severe burns were included and followed for 20 days. All had normal kidney function at admission. BNP and proteinuria were routinely measured. Ordered and actually administered fluid resuscitation volumes were recorded. The Sequential Organ Failure Assessment (SOFA) score was used as the measure of outcome.

Results

BNP increased during follow-up, reaching a plateau level at Day 3. Based on median BNP levels at Day 3, patients were divided into those with low BNP and those with high BNP levels. Both groups had comparable initial SOFA scores. Patients with high BNP received less fluid from Days 3 to 10. Furthermore, patients with a high BNP at Day 3 had less morbidity, reflected by lower SOFA scores on the following days. To minimize effects of biological variability, proteinuria on Days 1 and 2 was averaged. By dividing the patients based on median BNP at Day 3 and median proteinuria, patients with high BNP and low proteinuria had significantly lower SOFA scores during the entire follow-up period compared to those patients with low BNP and high proteinuria.

Conclusions

Patients with higher BNP levels received less fluid. This might be explained by a lower capillary leakage in these patients, resulting in more intravascular fluid and consequently an increase in BNP. In combination with low proteinuria, possibly reflecting minimal systemic capillary leakage, a high BNP level was associated with a better outcome. BNP and proteinuria have prognostic potential in severely burned patients and may be used to adjust individual resuscitation.

Effect of training in the Emergency Management of Severe Burns on the knowledge and performance of emergency care workers as measured by an online simulated burn incident

OBJECTIVE

To determine the value of training for the Emergency Management of Severe Burns (EMSB) for medical and nursing staff working in emergency care as measured by their performance in a simulated burn incident online program.

METHODS

An Internet-based questionnaire, which included a simulated burn incident, was developed. All of the medical and nursing staff in hospital emergency departments and ambulance services in the Netherlands were invited to complete this questionnaire. The effect of EMSB training on the individual's knowledge of and performance in the emergency management of a burn victim was evaluated because some of the respondents had participated in EMSB training, whereas others had not.

RESULTS

Of the 280 responses received, 198 questionnaires were included in the analysis. The analyzed questionnaires were submitted by nurses (43%), ambulance workers (33%), and physicians (23%). Only 14% of the people in the study had participated in EMSB training, whereas 78% had received other or additional life support training and 22% of respondents had no additional life support training. Medical and nursing staff who had participated in EMSB training performed better in the following subjects: mentioning hypothermia as a focus of attention (70% versus 53%, p=0.085), correct use of hand size (70% versus 36%, p=0.001) and use of the correct hand percentage in the estimation of total body surface area (TBSA, 82% versus 57%, p=0.015), suspicion of no airway obstruction in an outdoor trauma (93% versus 63%, p = 0.002) and referral of functional area burns to a burn center (22% versus 8%, p = 0.04). However, both groups overestimated the TBSA (34% of the total group overestimated ≥ 20%) and did not know the correct formula for fluid resuscitation (87% of the total group).

CONCLUSION

There is some evidence that medical staff members who have participated in EMSB training have a better knowledge of emergency management and are more effective in the management of a simulated burn case. However, both individuals who had participated in EMSB as well as those who had not participated in EMSB needed additional training in EMSB.
