Effect of Rural Trauma Team Development on the Outcomes of Motorcycle Accident-Related Injuries (Motor Registry Project): Protocol for a Multicenter Cluster Randomized Controlled Trial.

BACKGROUND: Injury is a global health concern, and injury-related mortality disproportionately impacts low- and middle-income countries (LMICs). Compelling evidence from observational studies in high-income countries shows that trauma education programs, such as the Rural Trauma Team Development Course (RTTDC), increase clinician knowledge of injury care. There is a dearth of such evidence from controlled clinical trials to demonstrate the effect of the RTTDC on process and patient outcomes in LMICs. OBJECTIVE: This multicenter cluster randomized controlled clinical trial aims to examine the impact of the RTTDC on process and patient outcomes associated with motorcycle accident-related injuries in an African low-resource setting. METHODS: This is a 2-arm, parallel, multi-period, cluster randomized, controlled, clinical trial in Uganda, where rural trauma team development training is not routinely conducted. We will recruit regional referral hospitals and include patients with motorcycle accident-related injuries, interns, medical trainees, and road traffic law enforcement professionals. The intervention group (RTTDC) and control group (standard care) will include 3 hospitals each. The primary outcomes will be the interval from the accident to hospital admission and the interval from the referral decision to hospital discharge. The secondary outcomes will be all-cause mortality and morbidity associated with neurological and orthopedic injuries at 90 days after injury. All outcomes will be measured as final values. We will compare baseline characteristics and outcomes at both individual and cluster levels between the intervention and control groups. We will use mixed effects regression models to report any absolute or relative differences along with 95% CIs. We will perform subgroup analyses to evaluate and control confounding due to injury mechanisms and injury severity. We will establish a motorcycle trauma outcome (MOTOR) registry in consultation with community traffic police. RESULTS: The trial was approved on August 27, 2019. The actual recruitment of the first patient participant began on September 01, 2019. The last follow-up was on August 27, 2023. Posttrial care, including linkage to clinical, social support, and referral services, is to be completed by November 27, 2023. Data analyses will be performed in Spring 2024, and the results are expected to be published in Autumn 2024. CONCLUSIONS: This trial will unveil how a locally contextualized rural trauma team development program impacts organizational efficiency in a continent challenged with limited infrastructure and human resources. Moreover, this trial will uncover how rural trauma team coordination impacts clinical outcomes, such as mortality and morbidity associated with neurological and orthopedic injuries, which are the key targets for strengthening trauma systems in LMICs where prehospital care is in the early stage. Our results could inform the design, implementation, and scalability of future rural trauma teams and trauma education programs in LMICs.

The Jerusalem tribune collapse incident: Challenges in the management of a pediatric mass casualty incident.

OBJECTIVES: Children comprise up to 30-50 percent of all disaster victims. Pediatric disaster medicine is a poorly established field, and most protocols are designed without adequate emphasis on the special needs of the pediatric population. During the 2021 Shavuot holiday in Israel, the collapse of temporary steel bleachers in a partially constructed synagogue resulted in a mass casualty incident (MCI) with a majority of pediatric casualties. This study analyzed the differences in post-incident casualty management, treatment, and outcomes in three Jerusalem medical centers. METHODS: Multicenter retrospective data were collected from two tertiary level 1 trauma centers and one secondary hospital in Jerusalem. The data included demographics, triage scores, injury mechanisms, medical workups, and the management of the pediatric patients. RESULTS: A total of 171 children and adolescents aged 9-18 years presented to three centers. In two institutions, the triage was performed by a senior emergency medicine physician, and in the third institution, by a senior trauma physician. Different protocols were applied, resulting in significant differences in triage, identification and documentation, admission strategies, adherence, and analgesic treatment. Most patients presented with orthopedic injuries (115/171, 67 percent). A small number had head, chest, abdominal, and multisystem injuries (11, 5, 2, and 2 percent, respectively). CONCLUSION: Pediatric MCI management presents specific challenges. The lack of consistency in triage, registry, and management highlights the need for robust pediatric MCI training programs.

Multidisciplinary expert consensus statements and recommendations for use of hypochlorous acid as a solution for negative pressure wound therapy with instillation.

BACKGROUND: HOCl (eg, pHAp) preserved solutions have antimicrobial properties and are considered safe and effective for wound management. NPWTi-d (or NPWTi) is an established adjunctive wound modality for a variety of wound etiologies in various anatomic locations in which an instillate solution dwells on the surface of the wound to assist in wound bed preparation. A variety of solutions have been used, including 0.9% normal saline wound cleansers and antiseptics. pHAp is growing in popularity as the solution of choice for NPWTi-d. OBJECTIVE: To evaluate consensus statements on the use of NPWTi-d with pHAp. METHODS: A 15-member multidisciplinary panel of expert clinicians in the United States, Canada, and France convened in person in April 2023 in Washington, D.C. and/or corresponded later to discuss 10 statements on the use of pHAp with NPWTi-d. The panelists then replied "agree" or "disagree" to each statement and had the option to provide comments. RESULTS: Ten consensus statements are presented, along with the proportion of agreement or disagreement and summary comments. Although agreement with the statements on NPWTi-d with pHAp varied, the statements appear to reflect individual preferences for use rather than concerns about safety or efficacy. CONCLUSION: The consensus indicates that NPWTi-d with pHAp can have a beneficial effect in wound care.

The importance of the simulated wound fluid composition and properties in the determination of the fluid handling performance of wound dressings.

Effective fluid handling by wound dressings is crucial in the management of exuding wounds through maintaining a clean, moist environment, facilitating healing by removing excess exudate and promoting tissue regeneration. In this context, the availability of reliable and clinically relevant standardised testing methods for wound dressings are critical for informed decision making by clinicians, healthcare administrators, regulatory/reimbursement bodies and product developers. The widely used standard EN 13726 specifies the use of Solution A, an aqueous protein-free salt solution, for determining fluid-handling capacity (FHC). However, a simulated wound fluid (SWF) with a more complex composition, resembling the protein, salt, and buffer concentrations found in real-world clinical exudate, would provide a more clinically relevant dressing performance assessment. This study compared selected physicochemical parameters of Solution A, an alternative, novel simulated wound fluid (SWF A), and a benchmark reference serum-containing solution (SCS) simulating chronic wound exudate. Additionally, FHC values for eight advanced bordered and non-bordered foam dressings were determined for all three test fluids, following EN 13726. Our findings demonstrate a close resemblance between SWF A and SCS. This study highlights the critical importance of selecting a physiochemically appropriate test fluid for accurate FHC testing resulting in clinically meaningful evaluation of dressing performance.

Medical Events Encountered at a Major International Airport and Health Services Provided.

INTRODUCTION: Travel by airline starts and ends at airports. Thousands of people consisting of passengers, relatives of passengers, and employees gather at airports every day. In this study, medical events (MEs) encountered at Istanbul Atatürk Airport (IAA) and health services provided were analyzed.METHODS: The MEs encountered in IAA between January 1, 2016, and December 31, 2018, and health services provided by the private medical clinic in the airport terminal building were retrospectively analyzed.RESULTS: During the study period, 192,500,930 passengers traveled from the IAA and a total of 11,799 patients were seen at the clinic. There were 4898 (41.5%) male patients. The median age of the 9466 (80.2%) patients whose age was recorded was 34 (28-51) yr. Of 11,799 patients included in the present study, 9228 (78.21%) patients had medical complaints, 1122 (9.5%) patients had trauma complaints, 1180 patients (10%) were transferred to the hospital, and 269 (2.27%) patients required a certificate of preflight fitness. The most common medical complaint was gastrointestinal (1515 patients, 12.84%). The most common trauma was soft tissue injury (345 patients, 2.92%).DISCUSSION: MEs in airports can be as various and also critical as health conditions seen in emergency departments. It is important to provide medical services with an experienced medical team trained in aviation medicine and adequate medical equipment at airports.Ceyhan MA, Demir GG, Cömertpay E, Yildirimer Y, Kurt NG.

Key performance indicators to inform evaluation of wound care programmes for people with complex wounds: a protocol for systematic review.

OBJECTIVE: The objective of the systematic review is to examine and summarise the available evidence in the literature of the use of key performance indicators (KPIs) to inform evaluation of wound care programmes and services for people with hard-to-heal (complex) wounds. The need for wound care is expected to grow with the continued ageing of the population and the resulting increased development of chronic conditions. This expected increase necessitates improvement of wound care programmes and services and their ability to deliver quality, evidence-based and cost-effective practice. The current literature lacks a systematic assessment of KPIs to inform evaluation of wound care services and programmes across various settings, and how the KPIs are used to improve the quality of wound care and achieve desired outcomes. This protocol sets out how the systemtic review will be undertaken. METHOD: Primary studies will be screened from databases such as MEDLINE, CINAHL and Scopus, with unpublished studies and grey literature retrieved from Google Scholar and ProQuest Dissertations and Theses. The study titles and abstracts will be screened by two independent reviewers, using Covidence systematic review software to ensure they meet the inclusion criteria, who will then proceed with data extraction of the full-text using the standardised data extraction instrument. The reference lists of all studies selected for critical appraisal will be screened for additional publications. The two independent reviewers will critically appraise all studies undergoing full-text data extraction using the appropriate checklist from JBI SUMARI. At all stages, differences between reviewers will be resolved through discussion, with adjudication by a third, independent reviewer. RESULTS: Data points will be analysed with descriptive statistics and grouped, based on programme characteristics and publication status. Grey literature and peer-reviewed publications will form separate analyses. To answer review questions, the data will be summarised in a narrative format. A meta-analysis is not planned. At the time of writing, this protocol has been implemented up to the preliminary literature search. CONCLUSION: This review will address a current literature gap and systematically identify KPIs in wound care, allowing for programmes to evaluate their quality of care and improve their services in a methodical manner.

Microjet wound therapy versus sharp debridement on wound size reduction: a pilot randomised controlled trial.

OBJECTIVE: There are several methods of treating hard-to-heal (chronic) wounds, each differing in terms of efficiency, selectivity, speed, cost and pain. The objective is to activate a wound to initiate the healing cascade. For this pilot study we assessed the feasibility of a new microjet wound therapy technology compared to standard sharp debridement in wound outcomes. METHOD: A randomised, controlled, open-label pilot study was conducted in one outpatient wound clinic in Western Switzerland from March 2022 to May 2023. RESULTS: A total of 13 consecutive patients were randomly assigned to receive either microjet wound therapy (n=5) or standard mechanical debridement with instruments (n=8). As a feasibility study, there was insufficient power to detect significant differences between the groups. However, in the intervention group, our analysis may indicate a modestly faster reduction in wound area. Microjet wound therapy appears to alleviate patient anxiety and offer cost savings due to the potential for reduced time, as well as the number of required treatments. This meant fewer overall consultations. CONCLUSION: This study highlights a trend that may indicate that microjet therapy holds value in promoting faster healing of hard-to-heal wounds, and it provides a feasibility basis for a sufficiently powered multicentre trial.

The Observatoire en Ville des Plaies ExSudatives (VIPES) study: insight into the patient characteristics, epidemiology, previous management, and features of wounds treated in the French community setting.

BACKGROUND: Wounds that become complex and hard-to-heal are a challenge for all health care systems. Identifying and understanding the nature of these wounds is necessary to allow appropriate intervention. OBJECTIVE: To present the epidemiological outcomes of the VIPES study. MATERIALS AND METHODS: The prospective, observational VIPES study aimed to describe the use and investigate the performance of 2 wound dressings-a silicone foam and a gelling fiber-in the management of chronic and acute wounds in a community setting in France. RESULTS: Of 407 patients recorded, 285 were included in the analysis. The 184 chronic wounds included ulcers (venous/arterial/mixed, diabetic foot, and pressure) and malignant wounds. The 101 acute wounds included surgical and traumatic wounds. Of all wounds, 98.2% were exuding and 77.9% showed exudate pooling. Unhealthy wound edges and periwound skin were reported in 57.2% and 35.4% of wounds, respectively. Of all wounds, 78.6% were in treatment failure (poor exudate management or stagnant wound). The silicone foam dressing (n = 86) and the gelling fiber (n = 199) were generally used in wounds with low or moderate exudation, or moderate or high exudation, respectively. CONCLUSIONS: The VIPES study highlights that wounds can be complex and that community care practices in France warrant improvement. Practical and up-to-date wound management recommendations are needed.

Effect of Heated Saline Solution on Pain Intensity, Wound Bed Temperature, and Comfort during Chronic Wound Dressing Changes: Crossover Randomized Clinical Trial.

OBJECTIVE: To evaluate the use of heated saline solution during wound cleaning on the intensity of pain related to the procedure, the temperature of the wound bed, and the comfort of patients with chronic wounds. Further, to investigate patient preference in relation to the temperature of the solution used for cleaning. METHODS: Crossover, single-blind, clinical trial with 32 people with chronic wounds. Providers cleaned the wounds with room temperature and heated saline solution. Participants were randomized into group 1 A/B (heated solution first, room temperature second) or group 2 B/A (room temperature solution first, heated solution second), with a 10-minute washout period. Investigators evaluated pain intensity, wound bed temperature, and patient-reported comfort and preference. RESULTS: The heated solution was preferred (P = .04) and more often referred to as comfortable (P = .04) by the participants. There was no difference in pain intensity before and after cleaning with room temperature (2.03; P = .155) and heated saline (2.25; P = .44). The heated solution increased the temperature of the wound bed by 0.5 °C. CONCLUSIONS: Although heating saline solution could be an important comfort measure during dressing changes, quantitatively, the temperature of the solution did not significantly change the temperature of the wound bed nor the intensity of pain patients experienced.

Early Vital Sign Thresholds Associated with 24-Hour Mortality among Trauma Patients: A Trauma Quality Improvement Program (TQIP) Study.

BACKGROUND: Identifying patients at imminent risk of death is critical in the management of trauma patients. This study measures the vital sign thresholds associated with death among trauma patients. METHODS: This study included data from patients ≥15 years of age in the American College of Surgeons Trauma Quality Improvement Program (TQIP) database. Patients with vital signs of zero were excluded. Documented prehospital and emergency department (ED) vital signs included systolic pressure, heart rate, respiratory rate, and calculated shock index (SI). The area under the receiver operator curves (AUROC) was used to assess the accuracy of these variables for predicting 24-hour survival. Optimal thresholds to predict mortality were identified using Youden's Index, 90% specificity, and 90% sensitivity. Additional analyses examined patients 70+ years of age. RESULTS: There were 1,439,221 subjects in the 2019-2020 datasets that met inclusion for this analysis with <0.1% (10,270) who died within 24 hours. The optimal threshold for prehospital systolic pressure was 110, pulse rate was 110, SI was 0.9, and respiratory rate was 15. The optimal threshold for the ED systolic was 112, pulse rate was 107, SI was 0.9, and respiratory rate was 21. Among the elderly sub-analysis, the optimal threshold for prehospital systolic was 116, pulse rate was 100, SI was 0.8, and respiratory rate was 21. The optimal threshold for ED systolic was 121, pulse rate was 95, SI was 0.8, and respiratory rate was 0.8. CONCLUSIONS: Systolic blood pressure (SBP) and SI offered the best predictor of mortality among trauma patients. The SBP values predictive of mortality were significantly higher than the traditional 90mmHg threshold. This dataset highlights the need for better methods to guide resuscitation as initial vital signs have limited accuracy in predicting subsequent mortality.

A Standardized Treatment Pathway for Telehealth-Based Care of Chronic Wounds in Austria.

Chronic wounds present a significant healthcare challenge in Austria as well as in other countries. The interdisciplinary approach to wound treatment involving various caregivers, doctors, and relatives, poses challenges in documentation and information exchange. To overcome these barriers and promote patient-centered care, a new telehealth-supported treatment pathway for chronic wounds has been developed. The primary focus was to regularly update the status of the chronic wound by responding to predefined questions and transmitted images of the chronic wound. This was achieved by an interdisciplinary team of experts in chronic wound care, providing a new perspective for digital implementation in the healthcare system.

Defining wound bed conformability: a new testing methodology to assess the relative swelling rise of foam dressings.

OBJECTIVE: Using a dressing that expands and conforms to the wound bed upon exudate absorption is one of the best ways to promote wound healing. While many products claim wound bed conformability, no externally replicated or verified test methodology had been developed to quantify a wound dressing's ability to conform to the wound bed. The Relative Swelling Rise (RSR) test methodology was developed to measure the relative swelling rise of foam dressings upon fluid absorption, and offers a quantifiable and easily replicated method to measure wound bed conformability. METHOD: The RSR test method was developed, validated and reliability tested by Coloplast A/S, Denmark. External replication was provided by ALS Odense, Denmark (previously DB Lab). Circular fences provide a fixed diameter to apply and contain the fluid and prevent horizontal spreading in the test set-up. The swelling height is quantified relative to the fence's inner diameter, i.e., the ratio alpha (α), and allows evaluation of a material's ability to conform to the wound bed. RESULTS: Biatain Silicone foam products (n=3, Coloplast A/S, Denmark) were tested, all afforded an average α-ratio from 0.30 to 0.60. The relative standard deviations were between 1-3%, demonstrating the strength of the test. Robustness of the methodology was demonstrated through the internal validation study, the reliability study, and both an internal and external replication study, as well as a systematic literature review and expert review of the construct, content, criterion and generalisability of the method. CONCLUSION: Having a validated, effective and easily replicable testing method to quantify wound bed conformability of foam dressings is an important step towards achieving better healing outcomes.

Improving outcomes for patients with hard-to-heal wounds following adoption of the Wound Hygiene Protocol: real-world evidence.

OBJECTIVE: To evaluate the impact of a four-step biofilm-based wound care strategy, Wound Hygiene Protocol (WHP: cleanse, debride, refashion, and dress), on hard-to-heal wounds. METHOD: This was a prospective, real-world analysis of hard-to-heal wounds managed with the WHP that incorporated Aquacel Ag+ (Convatec Ltd., UK) dressings. Data were captured electronically between April 2021 and December 2022. The primary endpoint was change in wound volume from baseline to final assessment. RESULTS: A total of 693 wounds in 669 patients (median patient age: 74 years) were included in the analysis with a median treatment time of 31 days. Most health professionals were general nurses (50%) or nurse practitioners (38%). Patient homes (27%) and community clinics (27%) were the most common clinical settings. Venous leg ulcers (26%) and pressure ulcers/injuries (17%) were the most common wound type. Duration was >12 months in 21% of wounds. At baseline, the mean wound volume was 57.8cm3. At the final assessment, mean wound volume was 17.2cm3, corresponding to an 80% reduction from baseline; p<0.001). At baseline, 66% of wounds were static or deteriorating. At final assessment, this had decreased to 5%, and 94% had improved or healed. Exudate levels were moderate or high in 69% of wounds at baseline which decreased to 25% at final assessment (p<0.001). Suspected biofilm and local wound infection decreased from 79% and 43%, respectively, at baseline, to 18% and 3%, respectively, at final assessment (p<0.001 for both). CONCLUSION: The WHP is a new proposed standard of care that successfully treated hard-to-heal wounds by addressing the key local barriers to wound healing.

[Clinical application of photobiomodulation in trauma repair and medical aesthetics].

In recent years, with the deepening of researches on the molecular biological mechanisms of photobiomodulation (PBM), PBM has gradually been applied in clinical practice, providing effective treatment methods and approaches for various diseases. Compared with traditional photothermal therapy, PBM has the characteristics of good therapeutic effect, almost no adverse reaction, and simple operation, and its clinical efficacy is becoming increasingly significant. This article provides a detailed explanation on the mechanism of PBM, its application characteristics and development trends in trauma repair and medical aesthetics, in order to provide a theoretical basis for the extensively clinical application of this therapy.
