ABSTRACT

BACKGROUND: To ensure a safe patient discharge from hospital it is necessary to transfer all relevant information in a discharge summary (DS). The aim of this study was to evaluate a bundle of measures to improve the DS for physicians, nurses and patients. METHODS: In a double-blind, randomized, controlled trial, four different versions of DS (2 original, 2 revised) were tested with physicians, nurses and patients. We used an evaluation sheet (Case report form, CRF) with a 6-point Likert scale (1 = completely agree; 6 = strongly disagree). RESULTS: In total, 441 participants (physicians n = 146, nurses n = 140, patients n = 155) were included in the study. Overall, the two revised DS received significant better ratings than the original DS (original 2.8 ± 0.8 vs. revised 2.1 ± 0.9, p < 0.001). Detailed results for the main domains are structured DS (original 1.9 ± 0.9 vs. revised 2.2 ± 1.3, p = 0.015), content (original 2.7 ± 0.9 vs revised 2.0 ± 0.9, p < 0.001) and comprehensibility (original 3.8 ± 1.2vs. revised 2.3 ± 1.2, p < 0.001). CONCLUSION: With simple measures like avoiding abbreviations and describing indications or therapies with fixed contents, the DS can be significantly improved for physicians, nurses and patients at the same time.

ABSTRACT

For over five decades, many experimental and clinical studies have shown predominantly positive but controversial results on the efficacy of hyperbaric oxygen (HBO2) therapy in burns. The study aimed to define a common denominator or constellations, respectively, linked to the effects of HBO2 in burns with a special focus on dosage parameters. Based on original work since 1965, species, number of individuals, type of study, percentage of total body surface area (TBSA), region, depth of burn, causative agent, interval between burn and first HBO2 session, pressure, duration of individual session, number of HBO2 sessions per day, cumulative number of HBO2 sessions and type of chamber were assessed. Out of 47 publications included, 32 were animal trials, four were trials in human volunteers, and 11 were clinical studies. They contained 94 experiments whose features were processed for statistical evaluation. 64 (67.4%) showed a positive outcome, 16 (17.9%) an ambiguous one, and 14 (14.7%) a negative outcome. The only factor independently influencing the results was pressure with ATA (atmospheres absolute) lower than 3 ATA being significantly associated with better outcomes (p=0.0005). There is a dire need for well-designed clinical studies in burn centers equipped with hyperbaric facilities to establish dedicated treatment protocols.

ABSTRACT

The vascularized fibula transfer is a well-established technique for extremity reconstruction, but operative planning and patient selection remains crucial. Although recently developed techniques for bone reconstruction, such as bone segment transfer, are becoming increasingly popular, bone defects may still require vascularized bone grafts under certain circumstances. In this study, 41 cases, 28 (68%) men and 13 (32%) women (median age: 40 years), were retrospectively analyzed. Therapy-specific data (flap vascularity [free vs. pedicled] size in cm and configuration [single- vs. double-barrel], mode of fixation [internal/external]) and potential risk factors were ascertained. Indications for reconstruction were osteomyelitis at host site (n = 23, 55%), pseudarthrosis (n = 8, 20%), congenital deformity (n = 6, 15%), traumatic defect, and giant cell tumor of the bone (n = 2, 5% each). Complete healing occurred in 34 (83%) patients after a median time of 6 months. Confounders for prolonged healing were female gender (p = 0.002), reconstruction in the lower limb (p = 0.011), smoking (p = 0.049), and the use of an external fixator (p = 0.009). Six (15%) patients required secondary limb amputation due to reconstruction failure, and one patient had persistent pseudarthrosis at last follow-up. The only risk factor for amputation assessed via logistic regression analysis was preexisting PAOD (peripheral artery occlusive disease; p = 0.008) The free fibula is a reliable tool for extremity reconstruction in various cases, but time to full osseous integration may exceed six months. Patients should be encouraged to cease smoking as it is a modifiable risk factor.

ABSTRACT

War-related burns are common injuries, also among the civilian population. Additional trauma such as fractures or shrapnel wounds may add significant morbidity. Burn injuries in war zones are furthermore frequently undertreated and hence prone to complications. We report a case of a young female victim of war, whose severely infected burn wounds could be successfully healed using a combination of targeted antimicrobial therapy, wound conditioning using decellularized fish skin, and subsequent skin grafting.

ABSTRACT

Wound healing is a complex process requiring an adequate supply of the wound area with oxygen and nutrients by neo-vascularization, to renew tissue. Local ischemia can result in the formation of chronic wounds. Since there is a lack of wound healing models for ischemic wounds, we aimed to develop a new one, based on chick chorioallantoic membrane (CAM) integrated split skin grafts and induction of ischemia with photo-activating Rose Bengal (RB) in a two-part study: (1) investigation of the thrombotic effect of photo-activated RB in CAM vessels and (2) investigation of the influence of photo-activated RB on CAM integrated human split skin xenografts. In both study phases, we observed a typical pattern of vessel changes after RB activation with a 120 W 525/50 nm green cold light lamp in the region of interest: intravascular haemostasis and a decrease in vessel diameter within 10 min of treatment. In total, the diameter of 24 blood vessels was measured before and after 10 min of illumination. Mean relative reduction of vessel diameter after treatment was 34.8% (12.3%-71.4%; p < 0.001). The results indicate that the present CAM wound healing model can reproduce chronic wounds without inflammation due to the statistically significant reduction of blood flow in the selected area using RB. Combined with xenografted human split skin grafts, we established the set up for a new chronic wound healing model for the research of regenerative processes following ischemic damage of the tissue.

ABSTRACT

PURPOSE: Burn injuries are to this day a major cause of morbidity and mortality, especially within low- and middle-income countries. Understanding the etiology of burn injury and epidemiologic- and hospital-specific factors associated with burns is vital for allotting resources for prevention and treatment. Therefore, the purpose of this study was to develop a profile of epidemiological differences in burn care and the ideal burn dressing among the different continents based on a global online survey. OBJECTIVES: This analysis evaluated trends in demographics, epidemiology of burn care, burn incidence, infection, related mortality and burn treatment (e.g., dressing changes and materials). The objective of this study was to investigate and compare the epidemiological profile of burn injury/care amongst the continents and a global control group to determine their utility for guiding evidence-based burn care and identify differences and/or similarities in their clinical practice. METHODS: A retrospective analysis of data was performed that was acquired during a previous study investigating the ideal burn dressing on a global perspective. The data was analyzed depending on the continent, on which the respondent indicated their hospital to be (Africa, Australia & New Zealand, Asia, Europe, Middle and South America, North America). Statistical analysis was performed to evaluate patient and hospital demographics and variables associated with burn injuries and their treatment. Outcomes of interest also included infections, mortality, length of stay on the ICU and important burn dressing characteristics. RESULTS: Healthcare providers in different areas of the world share similar views and needs regarding burn care management and on what constitutes an ideal burn dressing. We found significant differences in the various continents regarding hospitalization and length of stay on the ICU, with Australia taking the lead. Africa, with a high proportion of low-income-countries, reported the highest rate of burn infections, mortality, and a disproportionally high number of burn incidences amongst children. In general, men were mostly obtaining burn injuries amongst all continents. We found no significant differences regarding the most important characteristics of an ideal burn dressing. CONCLUSION: Our results suggest significant epidemiological differences regarding burn injuries and care amongst the continents, possibly resulting from the different infrastructure and/or circumstances on the various continents. Future scientific studies need to focus on adequate pain management and designing longer lasting materials that contain the "ideal" properties, by also taking individual regional needs/desires and the patient's perspective and economic boundaries into account. This analysis has delivered valuable insights into the epidemiological differences and/or similarities amongst the various continents.

ABSTRACT

Background and Objectives: Burn wound healing and management continues to be a major challenge for patients and health care providers resulting in a considerable socio-economic burden. Recent advances in the development of applicable xenografts as an alternative to split-thickness skin grafts have allowed for the development of acellular fish skin. Acellular fish skin acts as a skin substitute, reducing inflammatory responses and advancing proinflammatory cytokines that promote wound healing. Due to these beneficial wound healing properties, acellular fish skin might represent an effective treatment approach in burn wound management. Materials and Methods: A systematic review of the literature, up to March 2022, was conducted using the electronic databases PubMed and Web of Science. Titles and abstracts were screened for the following key terms (variably combined): "fish skin", "fish skin grafts", "acellular fish skin", "Omega3 Wound matrix", "xenograft", "burn injury", "burns". Results: In total, 14 trials investigating the effects of acellular fish skin in burn wounds or split-thickness donor sites were determined eligible and included in the present review. Existing evidence on the use of acellular fish skin indicates an acceleration of wound healing, reduction in pain and necessary dressing changes as well as treatment-related costs and improved aesthetic and functional outcomes compared to conventional treatment options. Conclusions: Acellular fish skin xenografts may represent an effective, low-cost alternative in treatment of superficial- and partial-thickness burns. However, results mainly originate from preclinical and small cohort studies. Future larger cohort studies are warranted to elucidate the full potential of this promising approach.

ABSTRACT

Background and Objectives: After burns, social reintegration is a primary long-term objective. At the same time, substance-abuse disorders are more common in burn patients. The aim of this study was to assess prevalence of substance abuse pre- and postburn as well as living situation and relationship status relative to patient-reported health-related quality of life (HRQoL). Patients and Methods: Burn survivors treated as inpatients between 1 January 2012 and 31 December 2019 were retrospectively identified. Collected clinical data included: age, gender, time since injury, burn extent (%TBSA), and substance abuse. Patient-reported living situation, relationship status, smoking habits, alcohol and drug consumption pre- and postburn as well as the SF-36 study were ascertained via telephone survey. Inductive statistical analysis comprised uni- and multivariate testing. A p < 0.05 was considered as statistically significant. Results: A total of 128 patients, 93 (72.7%) men, with a mean age of 40.0 ± 15.7 years were included. Mean TBSA was 9.2 ± 11.0% and significantly lower in women (p = 0.005). General health SF-36 scores were significantly lower in women (67.6 ± 29.8) than men (86.0 ± 20.8, p = 0.002). Smoking decreased from 38.8% pre- to 31.1% postburn. A significant reduction in alcohol consumption was noted over time (p = 0.019). The rate of never-drinkers was 18.0% pre- and 27.3% postburn. Drug abuse was rare both pre- (7.8%) and postburn (5.3%). Living situation remained stable. None of the participants depended on assisted living or lived in a care facility postburn. In total, 75.8% and 67.2% were in a relationship pre- and postburn. Patients with higher alcohol consumption postburn were significantly more often male (p = 0.013) and had higher SF-36 general health scores (p < 0.001). Conclusions: HRQoL is better in men than in women after burn injury. A slight decrease in substance abuse postburn was noted. The connection between HRQoL and substance abuse after burn injuries needs to be investigated further in the future.

ABSTRACT

Background and Objectives: As advances in medicine are proceeding, so are treatment goals shifting from sheer mortality rates to improving HRQoL and social reintegration after burn injury. Following this trend, we aimed to assess HRQoL, employment and life satisfaction after burn injury to gain insight on confounding factors. Materials and Methods: This single-center follow-up study was conducted using the SF-36 V1.0 in German and further questions evaluating employment and life satisfaction. It reached 128 adult in-patients (recall 33.0%) with former burn injuries, treated between 2012 and 2019 at the Division of Plastic, Aesthetic and Reconstructive Surgery at the University Hospital of Graz. The questionnaire outcomes were set into relation with clinical data obtained from the medical records. Statistical analysis was performed with SPSS 27.0 for Windows. Results: Of the 128 participants, 72.7% were male and 27.3% female. The mean age at the time of injury was 40.0 ± 15.7 years and mean %TBSA among the study population was 9.2 ± 11.0%. The male patients had sustained more extensive injuries (p = 0.005). However, the female patients scored significantly (p < 0.05) and consistently lower in all the domains of the SF-36, except for "bodily pain" (p = 0.061). Moreover, the female patients scored lower in all the domains of life satisfaction, although significant differences were only found in the domains of fulfillment (p = 0.050) and mental wellbeing (p = 0.015). Furthermore, employment status differed significantly between the male and female patients before as well as after the burn injury. Proportionally less women were employed at both time points. Overall, unemployment had declined. Conclusions: Life satisfaction after burn injury in this study cohort seems to be good. Return to work has shown a promising trend. Strikingly, HRQoL and life satisfaction were lower in women after burn injury. Further research on the reasons for this gender discrepancy might improve HRQoL and life satisfaction after burns.

ABSTRACT

INTRODUCTION: Peripheral nerve stimulation (PNS), based on central nerve stimulation (Spinal Cord Stimulation - SCS), has proven to be a suitable therapy option for the treatment of complex regional pain syndrome (CRPS), especially in the area of the upper extremities. However, the evidence on PNS in the current literature is very scarce. MATERIAL AND METHODS: 11 patients suffering from CRPS 2 were selected for implantation of a peripheral nerve stimulation system according to strict selection criteria. There were 5 men and 6 women with a mean age of 46.4 (24-58) years. Preoperatively, the mean pain score quoted by the patients was 8.0 (±1.3) on the ten-part numeric rating scale (NRS). In 8 patients, electrodes were implanted in the upper extremity (brachial plexus), in 2 patients in the area of the lower extremity (sciatic nerve) and in one patient on both the upper and lower extremities. The 8 active electrode poles were implanted as parallel as possible on the target nerves and connected to an external stimulation device by means of extension electrodes. After a test phase of 5 days, with positive feedback by the patients and a pain reduction of at least 4 points on the NRS, objectified by a pain log kept by the patient, the definitive impulse generator was implanted. RESULTS: All 11 patients were successfully supplied with an implantable peripheral nerve stimulation system from Boston Scientific Inc. The mean pain reduction was 4.6 (±1.2) points on the NRS. The mean pain score postoperatively was 3.4 (±0.9). The postoperative course was uncomplicated in all patients. CONCLUSION: Peripheral nerve stimulation appears to be a suitable therapy option for the treatment of CRPS 2 when conservative and conventional surgical treatment methods have failed. The experience with our patients shows that neuropathic pain could be successfully reduced by an average of about 4 points on the NRS. Arthrogenous symptoms, on the other hand, were not influenced by the PNS. Since CRPS is a psychosomatic illness, the integration of PNS into a multimodal therapy concept with physiotherapy and occupational therapy and psychology is essential for the success of the treatment.

ABSTRACT

For more than six decades, hyperbaric oxygen (HBO) has been used for a variety of indications involving tissue repair. These indications comprise a wide range of diseases ranging from intoxications to ischemia-reperfusion injury, crush syndrome, central nervous injury, radiation-induced tissue damage, burn injury and chronic wounds. In a systematic review, the molecular mechanisms triggered by HBO described within the last two decades were compiled. They cover a wide range of pathways, including transcription, cell-to-cell contacts, structure, adhesion and transmigration, vascular signaling and response to oxidative stress, apoptosis, autophagy and cell death, as well as inflammatory processes. By analyzing 71 predominantly experimental publications, we established an overview of the current concepts regarding the molecular mechanisms underlying the effects of HBO. We considered both the abovementioned pathways and their role in various applications and indications.

ABSTRACT

BACKGROUND: Low health literacy has been associated with poor health outcome and impaired use of healthcare services. The hospital discharge letter represents a key source of medical information for patients and can be used to address the problem of low health literacy. The aim of this project was to develop and evaluate a new, patient-directed, version of the discharge letter. METHODS: Based upon two conventional discharge letters (CDL; one surgical and one medical letter), two new, patient-friendly discharge letters (PFDL) were designed following 5 key principles: short sentences, few abbreviations, large font size, avoidance of technical terms and no more than 4 pages length. Medical undergraduates were randomized into two blinded groups (CDL, PFDL) and asked to assess the assigned letter for the 3 domains structure, content and patient-friendliness. Subsections were rated on a 6-point Likert scale (1 = completely agree, 6 = completely disagree), the results of the survey were compared using the Mann-Whitney-U-Test with a p < 0.05 being the level of significance. RESULTS: In total, 74 undergraduates participated in this study. PFDL (35 participants) were rated significantly better than CDL (39 participants) regarding structure (median 1 vs. 2, p = 0.005), content (1 vs. 3, p < 0.001) and patient-friendliness (2 vs. 6, p < 0.001). Of all 17 subsections, PFDL were rated significantly better in 12 cases, and never worse than CDL. CONCLUSIONS: PFDL were rated significantly better than their CDL counterparts. Medical undergraduates were considered the ideal cohort, not being medical lays and yet unbiased regarding everyday clinical practice procedures. Further tests evaluating the impact of the PFDL on patient comprehension and health literacy are necessary.

ABSTRACT

INTRODUCTION: In spring 2020, the COVID-19 pandemic required far-reaching changes and measures of unprecedented extent. These measures were implemented to reduce virus spread and to ensure the continuity of nation-wide medical care, in particular with a view to having sufficient intensive-care capacities in case of a large caseload of patients infected with COVID-19. With regard to surgical specialties, this implied a temporary hold on elective cases for an indefinite period of time. The aim of this study was to assess the impact of these measures on the caseload of a level-three plastic surgery unit. METHODS: This study retrospectively assessed the caseload at the Division of Plastic, Aesthetic and Reconstructive Surgery at Medical University Graz during the so-called lockdown from 16 March 2020 to 27 April 2020 (6 weeks) as well as two weeks before. The data was compared with the corresponding time period of the year 2019. Surgical spectrum, procedural urgency, medical indication of surgical procedures as well as complication rates were compared. RESULTS: The suspension of elective cases led to a significant reduction in caseload of 57.5 % (2019: 353, 2020: 150 cases). There was a significant increase in emergency and acute case procedures performed during the lockdown compared with the previous year (2019: 41, 2020: 58 cases, p < 0.001). Furthermore, the number of self-inflicted injuries and suicide attempts increased significantly (2019: 0, 2020: 16 cases, p < 0.001). With regard to private and work-related injuries, there was no significant difference. Also, there was no difference in complication rates (2019: 6.8, 2020: 10 %, p = 0.219). CONCLUSION: A significant amount of surgical procedures in plastic surgery at a supraregional academic health centre consists of emergency, acute and urgent medically necessary cases. During the lockdown, surgical procedures were performed without a significant increase in complication rates. Despite challenges during the pandemic, high-quality patient care was provided throughout. To process less urgent yet important cases accumulated during the lockdown in a reasonable amount of time and maintaining the same level of high-quality care, additional capacities regarding operating rooms, hospital beds and outpatient care are needed. These results point out the importance of plastic surgery for medical care, in particular during times of crisis.

ABSTRACT

RATIONALE AND OBJECTIVE: The discharge summary (DS) is one of the most important instruments to transmit information to the treating general physician (GP). The objective of this study was to analyse important components of DS, structural characteristics as well as medical and general abbreviations. METHOD: One hundred randomly selected DS from five different clinics were evaluated by five independent reviewers regarding content, structure, abbreviations and conformity to the Austrian Electronic Health Records (ELGA) using a structured case report form. Abbreviations of all 100 DS were extracted. All items were scored on a 4-point Likert-type scale ranging from "strongly agree" to "strongly disagree" (or "not relevant"). Subsequently, the results were discussed among reviewers to achieve a consensus decision. RESULTS: The mandatory fields, reason for admission and diagnosis at discharge were present in 80% and 98% of DS. The last medication was fully scored in 48% and the recommended medication in 94% of 100 DS. There were significant overall differences among clinics for nine mandatory items. In total, 750 unexplained abbreviations were found in 100 DS. CONCLUSIONS: In conclusion, DS are often lacking important items. Particularly important are a detailed medication history and recommendations for further medication that should always be listed in each DS. It is thus necessary to design and implement changes that improve the completeness of DS. An important quality improvement can be achieved by avoiding the use of ambiguous abbreviations.

ABSTRACT

Background and Objectives: Hyperbaric oxygenation (HBO) denotes breathing of 100% oxygen under elevated ambient pressure. Since the initiation of HBO for burns in 1965, abundant experimental and clinical work has been done. Despite many undisputedly positive and only a few controversial results on the efficacy of adjunctive HBO for burn injury, the method has not yet been established in clinical routine. Materials and Methods: We did a retrospective analysis of the literature according to PRISMA-guidelines, from the very beginning of HBO for burns up to present, trying to elucidate the question why HBO is still sidelined in the treatment of burn injury. Results: Forty-seven publications (32 animal experiments, four trials in human volunteers and 11 clinical studies) fulfilled the inclusion criteria. Except four investigators who found little or no beneficial action, all were able to demonstrate positive effects of HBO, most of them describing less edema, improved healing, less infection or bacterial growth and most recently, reduction of post-burn pain. Secondary enlargement of burn was prevented, as microvascular perfusion could be preserved, and cells were kept viable. The application of HBO, however, concerning pressure, duration, frequency and number of treatment sessions, varied considerably. Authors of large clinical studies underscored the intricate measures required when administering HBO in severe burns. Conclusions: HBO unquestionably has a positive impact on the pathophysiological mechanisms, and hence on the healing and course of burns. The few negative results are most likely due to peculiarities in the administration of HBO and possibly also to interactions when delivering the treatment to severely ill patients. Well-designed studies are needed to definitively assess its clinical value as an adjunctive treatment focusing on relevant outcome criteria such as wound healing time, complications, length of hospital stay, mortality and scar quality, while also defining optimal HBO dosage and timing.

ABSTRACT

The first half of the year 2020 has been shaped by quarantines and lock-downs all over the world. The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic, that slowed down not only social interactions and economy, but also medical and health care. Governments and hospitals were forced to create ad hoc emergency plans maintaining the balance between an adequate participation in collective response of shutting-down to avoid a further spreading of the virus, while preserving the ongoing acute care and simultaneously being able to react to an imminent overextension with a collapse of capacities. The University Hospital Graz is one of the largest hospitals in Austria. As transregional trauma and burn centre it provides care for people from all over Austria and faced special challenges. We present the strategy of the University Hospital Graz in dealing with the COVID-19 pandemic and the way back to (new) normality. The strategy includes infrastructural, patient-centred and staff-centred measures. The continuously low numbers of new infections in Austria allowed a loosening of the lock-down measures already. Particular attention has to be paid to attentive screening of patients and triaging of surgeries during the re-boot. The re-boot needs to be slow and steady to reduce the risk of an infectiological relapse. Once this pandemic is defeated, a careful re-evaluation of the different internationally applied strategies should be performed to be prepared for the future.

ABSTRACT

INTRODUCTION: Chemical burns are comparably rare but often result in full-thickness skin defects with frequent involvement of underlying structures. Hands are the most commonly affected injury site and impaired functional outcome is common. We present a case of an unusual chemical burn to the dorsum of the hand of a child secondary to application of a topical anti-wart treatment containing formic acid. CASE REPORT: An 11-year-old girl was referred to our outpatient department with a full-thickness injury resulting from a chemical burn having used a topical formic acid solution in the treatment of common warts. On examination, a 20-mm circular full-thickness defect was noted to the dorsum of the hand. The extensor tendons were not involved and there were no signs of infection. She required surgical debridement and local flap coverage. The postoperative recovery was unremarkable. CONCLUSION: Through a comprehensive literature review, four common topical solutions used in anti-wart treatment were identified to be associated with burns. Together with our case, this highlights the importance of careful patient education in the usage of common topical over-the-counter treatments.
