Study protocol for leaving care-A comparison study of implementation, change mechanisms and effectiveness of transition services for youth.

INTRODUCTION: Youth placed in out-of-home care is a large and highly vulnerable group at high risk of negative developmental outcomes. Given the size and extent of negative developmental outcomes for youth placed in out-of-home care, interventions to help this vulnerable group navigate successfully towards independent living and promote wellbeing across a spectrum of outcome areas are needed. To date, there is a lack of such interventions, particularly in Sweden. Importing interventions from other societies and cultures is associated with difficulties. The aim of the research project is to implement, test, and evaluate interventions that have been recently developed in Swedish practice to close this gap. METHODS: The project has an ambitious and complex data collection and analysis strategy using qualitative, quantitative, and multiple information methods (hybrid effectiveness-implementation study) over the course of two years. Both the implementation and effectiveness of the interventions will be evaluated. The recently developed My Choice-My Way! leaving care program for youth aged 15+ will be the primary focus of the project and will be compared to usual services. CONCLUSIONS: The project has the potential to offer novel insights into how society can promote wellbeing across a spectrum of outcome areas for the high-risk group of youth transitioning from out-of-home care to independent living. As such, the project will have important implications for both research and practice. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05813197.

Wound infection among children with moderate burns - An explorative review of the association between reported frequency and diagnosis.

INTRODUCTION: The Linkoping burn centre in Sweden has, even though being a high income country, reported high burn wound infections (BWI) frequencies in scalded children compared to similar populations in other parts of the world. AIM: The aim was to investigate possible explanations for differences in frequency of BWI among children with partial thickness burns treated at the Linköping burn centre in Sweden, and that reported in other studies. METHOD: In order to investigate what BWI criteria that were used in similar studies a literature search on PubMed Central was done along with a retrospective analysis of children previously diagnosed as infected to confirm or reject the high infection frequency reported earlier. RESULT: Of the 34 selected publications reporting on BWI frequency 16 (47%) did not define a criteria for the BWI diagnosis and almost a third did not report on wound culturing. Of those who did report the use a third do not mention any bacterial growth found is these cultures. The retrospective analysis on children at the centre did not show any decrease in infection frequency even with some disagreement on onset for the BWI. CONCLUSION: The reporting of criteria and diagnosis of burn wound infection is highly variable making it difficult to interpret results and come to conclusions. The high frequency of BWI at the centre might be a result of close monitoring due to study participation, use of clean instead of sterile routine at dressing changes or low thresholds for the diagnosis in respect to changes in infection markers.

Suprathel® or Mepilex® Ag for treatment of partial thickness burns in children: A case control study.

AIM: The study aim was to investigate if Suprathel® can be an adequate alternative to Mepilex® Ag for the treatment of partial-thickness scalds in children. METHODS: A retrospective study including 58 children admitted to The Burn Centre in Linköping, Sweden between year 2015 and 2022. Of the 58 children, 30 were dressed with Suprathel ® and 28 with Mepilex ® Ag. Outcomes investigated were healing time, burn wound infection (BWI), need for operations and number of dressing changes. RESULTS: We found no significant differences in any of the outcomes. In the Suprathel ® group 17 children and in the Mepilex ® Ag group 15 children were healed within 14 days. Ten children from each group received antibiotics for suspected BWI and two from each group underwent an operation with skin grafting. Each group had on median four dressing changes. CONCLUSIONS: Two different treatments were compared for children with partial-thickness scalds, and the data indicates that similar results are received with both dressings.

A prospective dual-centre intra-individual controlled study for the treatment of burns comparing dermis graft with split-thickness skin auto-graft.

To investigate if donor and recipient site morbidity (healing time and cosmesis) could be reduced by a novel, modified split-thickness skin grafting (STSG) technique using a dermal component in the STSG procedure (DG). The STSG technique has been used for 150 years in surgery with limited improvements. Its drawbacks are well known and relate to donor site morbidity and recipient site cosmetic shortcomings (especially mesh patterns, wound contracture, and scarring). The Dermal graft technique (DG) has emerged as an interesting alternative, which reduces donor site morbidity, increases graft yield, and has the potential to avoid the mesh procedure in the STSG procedure due to its elastic properties. A prospective, dual-centre, intra-individual controlled comparison study. Twenty-one patients received both an unmeshed dermis graft and a regular 1:1.5 meshed STSG. Aesthetic and scar assessments were done using The Patient and Observer Scar Assessment Scale (POSAS) and a Cutometer Dual MPA 580 on both donor and recipient sites. These were also examined histologically for remodelling and scar formation. Dermal graft donor sites and the STSG donor sites healed in 8 and 14 days, respectively (p < 0.005). Patient-reported POSAS showed better values for colour for all three measurements, i.e., 3, 6, and 12 months, and the observers rated both vascularity and pigmentation better on these occasions (p < 0.01). At the recipient site, (n = 21) the mesh patterns were avoided as the DG covered the donor site due to its elastic properties and rendered the meshing procedure unnecessary. Scar formation was seen at the dermal donor and recipient sites after 6 months as in the standard scar healing process. The dermis graft technique, besides potentially rendering a larger graft yield, reduced donor site morbidity, as it healed faster than the standard STSG. Due to its elastic properties, the DG procedure eliminated the meshing requirement (when compared to a 1:1.5 meshed STSG). This promising outcome presented for the DG technique needs to be further explored, especially regarding the elasticity of the dermal graft and its ability to reduce mesh patterns.Trial registration: ClinicalTrials.gov Identifier (NCT05189743) 12/01/2022.

Sociodemographic Patterns of Pediatric Patients in Specialized Burn Care in Sweden.

Trauma is a leading cause of mortality in children. Burns affect children disproportionally. Although burn incidence and mortality are decreasing, differences in the risk depend on socioeconomic status. The present study aimed to investigate the sociodemographic patterns of pediatric patients (0-17 years) managed at the two burn centers in Sweden, Uppsala, and Linköping, between 2010 and 2020. Method: This retrospective register-based study used hospital records from the two burn centers combined with information from Statistics Sweden plus data regarding number of asylum seekers from the Swedish Migrations Agency. Choropleth maps representing the patients' geographical distribution were created. Information about income levels per geographic area was added. A Wilcoxon signed-rank test was performed to investigate differences in median income levels between the areas where the patients lived, related to Sweden's median income. Results: The study included 2455 patients. Most of the children aged below 5 years (76%) and were boys (60%). The mean percentage of total skin area was 4.2%. There was no significant increment or decrease in the incidence of pediatric burns during the study. Most patients with recorded zip codes lived in areas with an income level below the national median (n = 1974, 83%). Children with asylum status were over-represented compared with residents and/or Swedish citizens. Conclusions: In Sweden, most pediatric burns occur in families that live in areas with low-income levels. Pediatric burns affect children with asylum status disproportionally compared with those who are residents in and/or citizens of Sweden. Prevention strategies should be designed and implemented to alleviate this health inequity.

The natural history of prenatally diagnosed congenital pulmonary airway malformations and bronchopulmonary sequestrations.

BACKGROUND: The natural history of congenital pulmonary airway malformations (CPAM) and bronchopulmonary sequestrations (BPS) is not fully understood, and the management of the newborn with an asymptomatic lesion is a controversial issue. We aimed to study the natural history and outcome of CPAM/BPS at our institution with a policy of watchful waiting, and to investigate if any prognostic factors in the pre- and/or postnatal- period may predict the need for surgery. MATERIAL AND METHODS: A retrospective review study was conducted of children prenatally diagnosed with CPAM and/or BPS during the 18-year period, from 2002 to 2020. Data from the pre and postnatal period was collected and analysed. RESULTS: Sixty- six patients with prenatally observed lung lesions were entered in the study, with an overall survival rate of 94%. Fifty-six percent of the lesions decreased in size during gestation. Thirty-one percent had surgery and 69% could be managed conservatively with a median follow-up of 4 years. Nineteen percent developed symptoms after the neonatal period. Children with a presence of mediastinal shift on postnatal imaging (p = 0.003), with a high CVR (p = 0.005) and a large lesion size during gestation (p = 0.014) were significantly more likely to require surgery. CONCLUSION: Prenatal regression is common among prenatally diagnosed CPAM/BPS and the majority of children that are asymptomatic beyond the neonatal period will remain asymptomatic throughout their childhood. Future analysis with a longer follow-up might give new insights in order to identify children at risk of developing symptoms. LEVEL OF EVIDENCE: III.

Biosynthetic cellulose compared to porcine xenograft in the treatment of partial-thickness burns: A randomised clinical trial.

AIM: The aim was to compare two dressing treatments for partial-thickness burns: biosynthetic cellulose dressing (BsC) (Epiprotect® S2Medical AB, Linköping, Sweden) and porcine xenograft (EZ Derm®, Mölnlycke Health Care, Gothenburg, Sweden). METHODS: Twenty-four adults with partial-thickness burns were included in this randomized clinical trial conducted at The Burn Centers in Linköping and Uppsala, Sweden between June 2016 and November 2018. Time to healing was the primary outcome. Secondary outcomes were wound infection, pain, impact on everyday life, length of hospital stay, cost, and burn scar outcome (evaluated with POSAS). RESULTS: We found no significant differences between the two dressing groups regarding time to healing, wound infection, pain, impact on everyday life, duration of hospital stay, cost, or burn scar outcome at the first follow up. Burn scar outcome at the 12-month follow up showed that the porcine xenograft group patients scored their scars higher on the POSAS items thickness (p = 0.048) and relief (p = 0.050). This difference was, however, not confirmed by the observer. CONCLUSIONS: The results showed the dressings performed similarly when used in adults with burns evaluated as partial thickness.

Scarring at Donor Sites after Split-Thickness Skin Graft: A Prospective, Longitudinal, Randomized Trial.

OBJECTIVE: To investigate if previous findings on the association between dressing treatments and subjective opinion on final donor site scar outcome using the Patient and Observer Scar Assessment Scale (POSAS) can be confirmed objectively. The previous study showed that patients dressed with hydrofiber covered with film were more satisfied with their donor site scars than patients receiving porcine xenograft or polyurethane foam dressings. METHODS: Scar outcome measurements were assessed by a blinded observer using POSAS and the Cutometer dual MPA 580 device to measure the viscoelasticity of skin. RESULTS: A total of 17 participants were included in this study, five of whom were treated with hydrofiber, six with polyurethane foam, and another six with porcine xenograft. There were no significant differences among groups in any of the POSAS items or in the viscoelasticity measurements made with the Cutometer. CONCLUSIONS: The investigators could not confirm previous associations between dressing treatment and long-term donor site scars. No associations between donor sites' healing times and final scarring were found. Hypopigmentation was reported in 15 of 17 donor sites evaluated.

Burn scar outcome at six and 12 months after injury in children with partial thickness scalds: Effects of dressing treatment.

INTRODUCTION: In line with other researchers in the field of burns' care, we think that research investigating the long-term outcome of scars is largely lacking. As scarring is of the utmost importance to the patient, clinicians who treat burns must aim to find treatments that lead to a good end result. The aim of this study was to study scar outcomes at six and 12 months after injury. It is an extension of a previous randomised controlled trial (RCT) in which two dressings (porcine xenograft and silver foam dressing) were examined with respect to their ability to help heal partial thickness scalds. METHOD: Children aged six months - six years with acute partial thickness scalds, on the trunk, or extremities, or both, were included. In the previous study, the silver foam was found to have significantly shorter healing times than the xenograft. Children were assessed at six and 12 months after injury for this study, and photographs were taken of the burn site, and both the patient and observer scar assessment scale (POSAS) and the Vancouver scar scale (VSS) were completed and evaluated by blinded observers. RESULTS: Of the 58 children from the original RCT, 39 returned to the clinic for evaluation of their scars at six months, and 34 at 12 months after injury. There were no differences in POSAS, VSS total scores, or incidence of hypertrophic scarring between the different dressings. Fifteen children were assessed as having hypertrophic scarring, all of whom had healing times that had extended beyond 14 days. CONCLUSIONS: This study compared burn scarring after two different treatments for burns in children with partial-thickness scalds and the data suggested that neither dressing had a more favourable impact on scar outcome. The conclusion is, however, tempered by the non-return of all the patients to the follow up. However, as anticipated, regardless of the dressing used, longer healing times were associated with higher scar scores (more scarring) and hypertrophic scarring.

Superiority of silver-foam over porcine xenograft dressings for treatment of scalds in children: A prospective randomised controlled trial.

AIM: Our aim was to compare two different regimens for the treatment of children with partial-thickness scalds. These were treated with either a porcine xenograft (EZderm®, Mölnlycke Health Care, Gothenburg, Sweden) or a silver-foam dressing (Mepilex® Ag, Mölnlycke Health Care, Gothenburg, Sweden). METHODS: We organised a prospective randomised clinical trial that included 58 children admitted between May 2015 and May 2018 with partial-thickness scalds to The Burn Centre in Linkoping, Sweden. The primary outcome was time to healing. Secondary outcomes were pain, need for operation, wound infection, duration of hospital stay, changes of dressings, and time taken. RESULTS: The patients treated with silver-foam dressing had a significantly shorter healing time. The median time to 97% healing for this group was 9 (7-23) days compared to 15 (9-29) days in the porcine xenograft group (p = 0.004). The median time to complete healing for the silver-foam group was 15 (9-29) days and for the porcine xenograft group 20.5 (11-42) days (p = 0.010). Pain, wound infection, duration of hospital stay, and the proportion of operations were similar between the groups. Number of dressing changes and time for dressing changes were lower in the silver-foam dressing group (p = 0.03 for both variables). CONCLUSIONS: We compared two different treatments for children with partial-thickness scalds, and the data indicate that wound healing was faster, fewer dressing changes were needed, and dressing times were shorter in the silver-foam group.

Three Years' Experience of a Novel Biosynthetic Cellulose Dressing in Burns.

Objective: The use of porcine xenograft (PX) is widely spread in burn care. However, it may cause immunologic responses and other ethical and cultural considerations in different cultures. Therefore, there is a need for alternatives. The aim of this work is to test a novel biosynthetic cellulose dressing (Epiprotect®) on burn patients. Approach: Charts from 38 patients with superficial burns (SBs) (n = 18) or excised burns (n = 20) that got biosynthetic cellulose dressing instead of PX at a national burn center during 3 years were reviewed. Time to healing, length of stay, and wound infection were extracted from the medical records. Results: SBs hospitalization time was 11 days comparable to PXs reported by others. In the excised group, median duration of hospital stay was 35 days. Time to healing was 28 days. Seven wound infections were confirmed in the superficial group (39%) and 11 infections in the excised group (61%). Patients with superficial wounds reported pain relief on application. Innovation: A dressing (17 × 21 cm) consisting of biosynthetic cellulose replacing PX. Conclusion: Outcome of treatment of SBs or temporary coverage of excised deep burns with biosynthetic cellulose is comparable to treatment with PX. However, biosynthetic cellulose has benefits such as providing pain relief on application and ethical or cultural issues with the material is nonexistent.

C-reactive protein response patterns after antibiotic treatment among children with scalds.

BACKGROUND: Scalds are the most common cause of burns in children, yet there is little information available about the inflammatory response. The aim of the study was to investigate the response to treatment with antibiotics among scalded children by following the C-reactive protein (CRP) concentration, procalcitonin (PCT) concentration, and white blood cell count (WCC) during the first two weeks after injury. METHODS: All children with scalds who presented to the Burn Centre during 2010-2016 were included in this retrospective study. All measurements of CRP, PCT, and WCC from the first 14days after injury were recorded, and each patient's maximum values during days 0-2, 3-7, and 8-14 were used for calculations. Multivariable regression for panel data was used to study the inflammatory response after antibiotic treatment. RESULTS: A total of 216 children were included. C-reactive protein was 45mg/L (p<0.001) higher in the group treated with antibiotics, and decreased with 8.8mg/L per day over the studied time in this group, which was more than twice as fast as among the children who were not given antibiotics. CONCLUSION: The CRP response, among children with minor scalds treated with antibiotics, shows an appreciable rise during the first week of injury that subsided rapidly during the second week.

Scarring At Donor Sites After Split-Thickness Skin Graft: A Prospective, Longitudinal, Randomized Trial.

OBJECTIVE: The aim of this study was to evaluate scarring at split-thickness skin graft donor sites 8 years after surgery. METHODS: At surgery, 67 patients were randomized to hydrofiber, polyurethane foam, or porcine xenograft treatment. Scars were evaluated with the Patient and Observer Scar Assessment Scale. RESULTS: Results showed significant differences in observed scar outcomes at donor sites, leaving the polyurethane foam-treated and the porcine xenograft-treated patients with the least satisfying scars. Multivariable regression analysis showed that the group treated with the xenografts had worse scores for overall opinion of the scar than did the other groups (P = .03), the most important factor being pigmentation. There was no correlation between duration of healing time and quality of the scar. CONCLUSIONS: There were significant differences among the groups, with the hydrofiber group being the most satisfied with the appearance of their scar.

Automated VSS-based Burn Scar Assessment using Combined Texture and Color Features of Digital Images in Error-Correcting Output Coding.

Assessment of burn scars is an important study in both medical research and clinical settings because it can help determine response to burn treatment and plan optimal surgical procedures. Scar rating has been performed using both subjective observations and objective measuring devices. However, there is still a lack of consensus with respect to the accuracy, reproducibility, and feasibility of the current methods. Computerized scar assessment appears to have potential for meeting such requirements but has been rarely found in literature. In this paper an image analysis and pattern classification approach for automating burn scar rating based on the Vancouver Scar Scale (VSS) was developed. Using the image data of pediatric patients, a rating accuracy of 85% was obtained, while 92% and 98% were achieved for the tolerances of one VSS score and two VSS scores, respectively. The experimental results suggest that the proposed approach is very promising as a tool for clinical burn scar assessment that is reproducible and cost-effective.

Dressing the split-thickness skin graft donor site: a randomized clinical trial.

OBJECTIVE: The primary objective of this study was to compare Aquacel (ConvaTec, Skillman, New Jersey), Allevyn (Smith & Nephew, St Petersburg, Florida), and Mediskin I (Mölnlycke, Health Care AB, Gothenburg, Sweden) in the treatment of split-thickness skin graft donor sites. DESIGN: This study was performed as a prospective randomized, 3-arm, clinical study. SETTING: A clinical study performed at a hand and plastic surgery department with burn unit. PARTICIPANTS: The study included 67 adults with a total of 73 donor sites, which were on the thigh, not reharvested, and ranged between 30- and 400-cm area. INTERVENTIONS: Subjects were randomly assigned to treatment with Aquacel, Allevyn, or Mediskin I. MAIN OUTCOME MEASURES: The donor site was assessed on postoperative days 3, 14, and 21 for healing, infection, pain, impact on everyday life, ease of use, and cost. MAIN RESULTS: The obtained results demonstrate significantly faster re-epithelialization for patients treated with Aquacel or Mediskin I compared with Allevyn. Regarding infections, there were no significant differences between the groups. Patients wearing Aquacel experienced significantly less pain changing the dressing and less impact on everyday life than the patients wearing Allevyn. Aquacel was shown to be significantly easier for the caregiver to use than Allevyn and Mediskin I. There is a significant difference in cost of treatment between the dressings, whereas Mediskin I is the most expensive. CONCLUSION: The authors' results support the use of Aquacel in the treatment of split-thickness skin graft donor sites. Aquacel has a low cost per unit, is user friendly, gives short healing time, and minimizes patient discomfort.
