Exploring Experiences of Conflict within Medical Teams in an Emergency Department: A Focus Group Approach during the COVID-19 Pandemic.

The factors related to conflicts in emergency departments (EDs) have been studied for decades. The post-pandemic digital era may transform the medical landscape in EDs, potentially changing the patterns of conflict between healthcare professionals. This study used focus group interviews to explore conflicts in EDs. Four groups, each with 4-6 participants, took part in this study. Semi-structured interviews were conducted using six research questions. Summative content analysis was used to analyze the data. The participant's average age was 37.82 years, and the average number of working years was 12.12. The following five themes emerged: multiple patterns of internal conflict; external conflicts arising from cross-departmental coordination; conflicts due to unclear job boundaries; adapting to conflicts in diverse ways; and seeking hospital arbitration. The results of this study suggest extending interdisciplinary collaborative practice from emergency departments to all coordinating departments. An inclusive environment for equality between professions and open communication should be promoted by hospitals.

Impacts of interprofessional education on collaborative practice of healthcare professionals: A systematic review and meta-analysis.

OBJECTIVE: To investigate and statistically synthesise data on the effects of interprofessional education on healthcare professionals' collaborative practice among healthcare professionals. DESIGN: A systematic review and meta-analysis. DATA SOURCES: Seven databases and the grey literature were searched to collect relevant studies from database inception to 15 May 2023. REVIEW METHODS: A random-effects model was used to assess the pooled effect size. Each pooled analysis was tested for publication bias using Egger's regression test. RESULTS: Eleven studies were included in the final analysis. The evaluation of pooled results showed that interprofessional education significantly enhanced attitudes towards or mutual respect among healthcare professionals (pooled standardized mean difference: 0.14; 95 % Confidence Interval: 0.01-0.28; p = 0.04) and interprofessional knowledge (pooled standardized mean difference: 0.43; 95 % Confidence Interval: 0.22-0.65; p < 0.001). CONCLUSIONS: Interprofessional education is a feasible approach to enhance attitudes towards or mutual respect among healthcare professionals as well as their interprofessional knowledge. Future research is needed to consider the inclusion of a module designed to develop mutual interests and communication to enhance students' perspectives on the importance of the interprofessional education approach.

Interdisciplinary simulation-based teaching and learning for healthcare professionals: A systematic review and meta-analysis of randomized controlled trials.

AIM: This study aimed to investigate the effects of interdisciplinary simulation-based teaching and learning on the interprofessional knowledge of healthcare professionals. BACKGROUND: Interdisciplinary simulation-based teaching and learning have been employed to prepare learners to collaborate in clinical settings. This strategy could help healthcare professionals to better understand each other, develop interdisciplinary shared values and promote mutual respect between professions, while reducing errors and adverse events in hospital. A meta-analysis was performed to investigate the effects of interdisciplinary simulation-based teaching and learning on healthcare professionals. DESIGN: A systematic review and meta-analysis. METHODS: A systematic search was conducted of databases including Academic Search Complete, CINAHL Plus with full text, Cochrane Library, Embase, Medline Complete, PubMed and Web of Science from their inception to September 5, 2023. The study included randomized controlled trials that provided interdisciplinary simulation-based education to healthcare professionals. Protocol trials or studies that did not include median or mean and standard deviation were excluded. The pooled standardized mean differences of outcomes were analyzed using a DerSimonian-Laird random-effects model. Heterogeneity was assessed using I2. Egger's regression test was used to examine publication bias indicated in forest plots. RESULTS: Ten randomized control trials with a total of 766 participants were included in the pooled analyses. Interdisciplinary simulation-based teaching and learning positively enhanced the interprofessional knowledge of healthcare professionals (pooled SMD = 0.30; 95% CI = 0.10-0.50; p < 0.001). Egger's regression test results were non-significant, indicating that publication bias had little impact on the pooled SMDs. CONCLUSION: Interdisciplinary simulation-based teaching and learning for health professionals appear to be significantly beneficial for increasing their interprofessional knowledge. This strategy highlights the importance of providing a well-developed scenario with relevant properties, which applies valid and rigorous instruments, to measure behavioral changes induced by interdisciplinary simulation-based teaching and learning.

The Impact of Cefuroxime Susceptibility on Aeromonas Necrotizing Fasciitis Outcomes.

Despite aggressive antibiotic therapy and surgical debridement, Aeromonas necrotizing fasciitis (NF) can lead to high amputation and mortality rates. Our study compares the different antibiotic minimum inhibitory concentrations (MICs) via Epsilometer tests (E-tests) between non-survivors and survivors of Aeromonas NF of limbs. A prospective review of 16 patients with Aeromonas NF was conducted for 3.5 years in a tertiary coastal hospital. E-tests were conducted for 15 antimicrobial agents to determine the MIC value for Aeromonas species. These patients were divided into non-survival and survival groups. The clinical outcomes, demographics, comorbidities, presenting signs and symptoms, laboratory findings, and microbiological results between the two periods were compared. A total of four patients died, whereas 12 survived, resulting in a 25% mortality rate. A higher proportion of bloodstream infections (100% vs. 41.7%; p = 0.042), monomicrobial infections (100% vs. 33.3%; p = 0.021), shock (100% vs. 33.3%; p = 0.021), serous bullae (50% vs. 0%; p = 0.009), liver cirrhosis (100% vs. 25%; p = 0.009), chronic kidney disease (100% vs. 33.3%; p = 0.021), lower susceptibility to cefuroxime (25% vs. 83.3%; p = 0.028), and ineffective antibiotic prescriptions (75% vs. 16.7%; p = 0.029) was observed in non-survivors. Aeromonas NF is an extremely rare skin and soft-tissue infection that is associated with high mortality, bacteremia, antibiotic resistance, and polymicrobial infection. Therefore, antibiotic regimen selection is rendered very challenging. To improve clinical outcomes and irrational antimicrobial usage, experienced microbiologists can help physicians identify specific pathogens and test MIC.

Initial skin necrosis presentation at emergency room was associated with fulminant clinical course and mortality in patients with Vibrio necrotizing fasciitis.

Necrotizing fasciitis (NF) is a life-threatening infection. Skin necrosis is an important skin sign of NF. The purposes of this study was to investigate the initial skin conditions of Vibrio NF patients between emergency room (ER) to preoperative status, to compare the clinical and laboratory risk indicators of the skin necrosis group and non-skin necrosis group when they arrived at ER, and to evaluate whether initial cutaneous necrosis related to fulminant course and higher fatalities. From 2015 to 2019, seventy-two Vibrio NF patients with surgical confirmation were enrolled. We identified 25 patients for inclusion in the skin necrosis group and 47 patients for inclusion in the non-skin necrosis group due to the appearance of skin lesion at ER. Seven patients died, resulting in a mortality rate of 9.7%. Six patients of skin necrosis group and one patient of non-skin necrosis group died, which revealed the skin necrosis group had a significantly higher mortality rate than the non-skin necrosis group. All the patients in the skin necrosis group and 30 patients of non-skin necrosis group developed serous or hemorrhagic bullous lesions before operation (p = 0.0003). The skin necrosis group had a significantly higher incidence of APACHE score, postoperative intubation, Intensive care unit stay, septic shock, leukopenia, higher counts of banded leukocytes, elevated C-reactive protein (CRP), and lower serum albumin level. Vibrio NF patients presenting skin necrosis at ER were significantly associated with fulminant clinical courses and higher mortality. Physicians should alert the appearance of skin necrosis at ER to early suspect NF and treat aggressively by those clinical and laboratory risk indicators, such as elevated APACHE score, shock, leukopenia, higher banded leukocytes, elevated CRP, and hypoalbuminia.

Brain computed tomography reading of stroke patients by resident doctors from different medical specialities: An eye-tracking study.

BACKGROUND: Using the eye-tracking technique, our work aimed to examine whether difference in clinical background may affect the training outcome of resident doctors' interpretation skills and reading behaviour related to brain computed tomography (CT). METHODS: Twelve resident doctors in the neurology, radiology, and emergency departments were recruited. Each participant had to read CT images of the brain for two cases. We evaluated each participant's accuracy of lesion identification. We also used the eye-tracking technique to assess reading behaviour. We recorded dwell times, fixation counts, run counts, and first-run dwell times of target lesions to evaluate visual attention. Transition entropy was applied to assess the temporal relations and spatial dynamics of systematic image reading. RESULTS: The eye-tracking results showed that the image reading sequence examined by transition entropy was comparable among resident doctors from different medical specialties (p = 0.82). However, the dwell time of the target lesions was shorter for the resident doctors from the neurology department (4828.63 ms, p = 0.01) than for those from the resident doctors from the radiology (6275.88 ms) and emergency (5305.00 ms) departments. The eye-tracking results in individual areas of interest only showed differences in the eye-tracking performance of the first-run dwell time (p = 0.05) in the anterior cerebral falx. DISCUSSION: Our findings demonstrate that resident doctors from different medical specialties may achieve similar imaging reading patterns for brain CT. This may mitigate queries regarding the influence of different backgrounds on training outcomes.

Comparison of National Early Warning Score with shock index in patients with necrotizing fasciitis.

Shock index (SI) and national early warning score (NEWS) are more frequently used as assessment tools in acute illnesses, patient disposition and early identification of critical condition. Both they are consisted of common vital signs and parameters including heart rate, systolic blood pressure, respiratory rate, oxygen saturation and level of conscious, which made it easy to evaluate in medical facilities. Its ability to predict mortality in patients with necrotizing fasciitis (NF) in the emergency department remains unclear. This study was conducted to compare the predictive capability of the risk scores among NF patients. A retrospective cohort study of hospitalized patients with NF was conducted in 2 tertiary teaching hospitals in Taiwan between January 2013 and March 2015. We investigated the association of NEWS and SI with mortality in NF patients. Of the 395 NF patients, 32 (8.1%) died in the hospital. For mortality, the area under the receiver curve value of NEWS (0.81, 95% confidence interval 0.76-0.86) was significantly higher than SI (0.76, 95% confidence interval 0.73-0.79, P = .016). The sensitivities of NEWS of 3, 4, and 5 for mortality were 98.1%, 95.6%, and 92.3%. On the contrast, the sensitivities of SI of 0.5, 0.6, and 0.7 for mortality were 87.8%, 84.7%, and 81.5%. NEWS had advantage in better discriminative performance of mortality in NF patients. The NEWS may be used to identify relative low risk patients among NF patients.

Unreliable diagnostic accuracy of laboratory risk indicator for necrotizing fasciitis (LRINEC) score but good outcome predictor in necrotizing fasciitis due to Vibrio vulnificus : A retrospective and matched-pair study.

The diagnostic accuracy of laboratory risk indicator for necrotizing fasciitis (LRINEC) score system in specific Vibrio vulnificus (V vulnificus ) necrotizing fasciitis (NF) have not been fully investigated yet. This aim of our study is to validate the LRINEC score in patients with V vulnificus NF. A retrospective study of hospitalized patients was conducted in a hospital in southern Taiwan between January 2015 and December 2022. Clinical characteristics, variables and outcomes were compared among V vulnificus NF, non- Vibrio NF and cellulitis patients. A total of 260 patients were included, 40 in V vulnificus NF group, 80 in non- Vibrio NF group and 160 patients in cellulitis group. In V vulnificus NF group with an LRINEC cutoff score ≥ 6, the sensitivity was 35% (95% confidence interval [CI]: 29%-41%), specificity was 81% (95% CI: 76%-86%), PPV was 23% (95% CI: 17%-27%), and NPV was 90% (95% CI: 88%-92%). The AUROC for accuracy of the LRINEC score in V vulnificus NF was 0.614 (95% CI: 0.592-0.636). Multi-variable logistic regression analysis revealed that LRINEC > 8 was significantly associated with higher in-hospital mortality (adjusted odds ratio = 1.57; 95% CI: 1.43-2.08; P < .01). The LRINEC score may not be an accurate tool for V vulnificus NF. That should be used with caution as a routine diagnostic tool. However, LRINEC > 8 is significantly associated with higher mortality in V vulnificus NF patients.

Predictor of gram-negative bacteremia in cirrhotic patients with skin and soft-tissue infections.

Cirrhosis always goes with profound immunity compromise, and makes those patients easily be the target of skin and soft-tissue infections (SSTIs). Cirrhotic patients with SSTIs have a dramatically increased mortality. To recognize the risk factors of gram-negative infections are critical for improving survival rate. A retrospective cohort study of hospitalized cirrhotic patients with SSTIs and gram-negative bacteremia (GNB) was conducted in 2 tertiary hospitals in southern Taiwan between March 2015 and January 2020. Another group were matched by controls with non-GNB based on time, demographics and immune status. Data such as infectious location, comorbidities, and laboratory findings were recorded and compared. Receiver operating curve and the area under the curve were used to evaluate its discriminating ability. A total of 186 patients were included, 62 in GNB group and 124 in non-GNB group. Comorbidities that were significant risk factors for gram-negative bacteremia included acute kidney injury. Significant risk factors evident in laboratory evaluations included higher model for end-stage liver disease score, higher serum lactate, higher C-reactive protein and higher creatinine level. This study found acute kidney injury, or those exhibiting hyperlactatemia (>16 mg/dL), high MELD score (>14), high CRP (>50 mg/dL), and high creatinine (>2.0 mg/dL) were risk factors associated with gram-negative bacteremia. Cirrhotic patients with SSTIs with aforementioned risk factors should pay more attention by clinicians due to higher mortality.

Performance of Six Clinical Physiological Scoring Systems in Predicting In-Hospital Mortality in Elderly and Very Elderly Patients with Acute Upper Gastrointestinal Bleeding in Emergency Department.

Background and Objectives: The aim of this study is to compare the performance of six clinical physiological-based scores, including the pre-endoscopy Rockall score, shock index (SI), age shock index (age SI), Rapid Acute Physiology Score (RAPS), Rapid Emergency Medicine Score (REMS), and Modified Early Warning Score (MEWS), in predicting in-hospital mortality in elderly and very elderly patients in the emergency department (ED) with acute upper gastrointestinal bleeding (AUGIB). Materials and Methods: Patients older than 65 years who visited the ED with a clinical diagnosis of AUGIB were enrolled prospectively from July 2016 to July 2021. The six scores were calculated and compared with in-hospital mortality. Results: A total of 336 patients were recruited, of whom 40 died. There is a significant difference between the patients in the mortality group and survival group in terms of the six scoring systems. MEWS had the highest area under the curve (AUC) value (0.82). A subgroup analysis was performed for a total of 180 very elderly patients (i.e., older than 75 years), of whom 27 died. MEWS also had the best predictive performance in this subgroup (AUC, 0.82). Conclusions: This simple, rapid, and obtainable-by-the-bed parameter could assist emergency physicians in risk stratification and decision making for this vulnerable group.

Bullous skin signs and laboratory surgical indicators can quickly and effectively differentiate necrotizing fasciitis from cellulitis.

OBJECTIVES: The purpose of this prospective study was to investigate the different microorganisms associated with mortality, to evaluate the bullous skin sign, and to identify the positive predictive factors for differentiating necrotizing fasciitis (NF) from cellulitis on initial onset at the emergency department. METHODS: This prospective study was conducted in 145 consecutive patients with NF and 159 patients with cellulitis. Age, sex, comorbidities, infection site, microbiological results, condition of skin lesions, laboratory findings, vital signs, and clinical outcomes were compared between the two groups at the time of admission to the emergency room. RESULTS: A total of 15 patients in the NF group and two patients in the cellulitis group died, resulting in a mortality rate of 10.3% and 1.3%, respectively. The NF group had a significantly higher incidence of white blood cell counts, band form neutrophil, and C-reactive protein than the patients in the cellulitis group. Hemorrhagic bullae presentation appeared to have significantly associated with NF and death. CONCLUSION: The following diagnostic indicators can be effectively used to differentiate NF from cellulitis at the initial onset: presence of hemorrhagic bullae, white blood cell counts >11,000 cells/mm3, band forms >0%, C-reactive protein >100 mg/l, and systolic blood pressure ≤90 mm Hg at the time of consultation.

Rational Use of Antibiotics and Education Improved Aeromonas Necrotizing Fasciitis Outcomes in Taiwan: A 19-Year Experience.

BACKGROUND: Aeromonas necrotizing fasciitis (NF) causes high rates of amputation and mortality, even after aggressive surgical debridement and antibacterial therapy. This study investigated the effects of rational use of antibiotics and education by infectious disease (ID) physicians on Aeromonas NF treatment outcomes. METHODS: Retrospective review for conducted for four years (period I, without an ID physician, December 2001 to December 2005) and 15 years (period II, with an ID physician, January 2006 to March 2021). In period II, the hospital-wide computerized antimicrobial approval system (HCAAS) was also implemented. A pretest-posttest time series analysis compared the two periods. Differences in clinical outcomes, demographics, comorbidities, signs and symptoms, laboratory findings, Aeromonas antibiotic susceptibility, and antibiotic regimens were compared between the two periods. RESULTS: There were 19 patients in period I and 53 patients in period II. Patients had a lower rate of amputation or mortality in period II (35.8%) compared with period I (63.2%). Forty-four patients (61.1%) had polymicrobial infections. In the emergency room, the rate of misdiagnosis decreased from 47.4% in period I to 28.3% in period II, while effective empiric antibiotic usage increased from 21.1% in period I to 66.0% in period II. After the ID physician's adjustment, 69.4% received monotherapy in period II compared to 33.3% in period I. CONCLUSIONS: Because Aeromonas NF had a high mortality rate and was often polymicrobial, choosing an antibiotic regimen was difficult. Using the HCAAS by an experienced ID physician can improve rational antibiotic usage and clinical outcomes in Aeromonas NF.

Oral presentation assessment and image reading behaviour on brain computed tomography reading in novice clinical learners: an eye-tracking study.

BACKGROUND: To study whether oral presentation (OP) assessment could reflect the novice learners' interpretation skills and reading behaviour on brain computed tomography (CT) reading. METHODS: Eighty fifth-year medical students were recruited, received a 2-hour interactive workshop on how to read brain CT, and were assigned to read two brain CT images before and after instruction. We evaluated their image reading behaviour in terms of overall OP post-test rating, the lesion identification, and competency in systematic image reading after instruction. Students' reading behaviour in searching for the target lesions were recorded by the eye-tracking technique and were used to validate the accuracy of lesion reports. Statistical analyses, including lag sequential analysis (LSA), linear mixed models, and transition entropy (TE) were conducted to reveal temporal relations and spatial complexity of systematic image reading from the eye movement perspective. RESULTS: The overall OP ratings [pre-test vs. post-test: 0 vs. 1 in case 1, 0 vs. 1 in case 2, p < 0.001] improved after instruction. Both the scores of systematic OP ratings [0 vs.1 in both cases, p < 0.001] and eye-tracking studies (Case 1: 3.42 ± 0.62 and 3.67 ± 0.37 in TE, p = 0.001; Case 2: 3.42 ± 0.76 and 3.75 ± 0.37 in TE, p = 0.002) showed that the image reading behaviour changed before and after instruction. The results of linear mixed models suggested a significant interaction between instruction and area of interests for case 1 (p < 0.001) and case 2 (p = 0.004). Visual attention to the target lesions in the case 1 assessed by dwell time were 506.50 ± 509.06 and 374.38 ± 464.68 milliseconds before and after instruction (p = 0.02). However, the dwell times in the case 2, the fixation counts and the frequencies of accurate lesion diagnoses in both cases did not change after instruction. CONCLUSION: Our results showed OP performance may change concurrently with the medical students' reading behaviour on brain CT after a structured instruction.

Bridging the Gap: Using Consensus to Explore Entrustment Decisions and Feedback Receptivity in Competency-Based Emergency Medicine Residency Programs Through the Construction of a Q-Sample Incorporating a Delphi Technique.

Background: Recent changes in medical education calls for a shift toward student-centered learning. Therefore, it is imperative that clinical educators transparently assess the work-readiness of their medical residents through entrustment-based supervision decisions toward independent practice. Similarly, it is critical that medical residents are vocal about the quality of supervision and feedback they receive. This study aimed to explore the factors that influence entrustment-based supervision decisions and feedback receptivity by establishing a general consensus among Taiwanese clinical educators and medical residents regarding entrustment decisions and feedback uptake, respectively. Methods: In Q-methodology studies, a set of opinion statement (i.e., the Q-sample) is generated to represent the phenomenon of interest. To explore the factors that influence entrustment-based supervision decisions and feedback receptivity, a Q-sample was developed using a four-step approach: (1) literature search using electronic databases, such as PubMed and Google Scholar, and interviews with emergency clinical educators and medical residents to generate opinion statements, (2) thematic analysis and grouping using The Model of Trust, the Ready, Wiling, and Able model, and the theory of self-regulated learning, (3) translation, and (4) application of a Delphi technique, including two expert panels comprised of clinical educators and medical residents, to establish a consensus of the statements and validation for a subsequent Q-study. Results: A total of 585 and 1,039 statements from the literature search and interviews were extracted to populate the sample of statements (i.e., the concourse) regarding entrustment-based supervision decisions for clinical educators and feedback receptivity emergency medicine residents, respectively. Two expert panels were invited to participate in a Delphi Technique, comprised of 11 clinical educators and 13 medical residents. After two-rounds of a Delphi technique, the panel of clinical educators agreed on 54 statements on factors that influence entrustment-based supervision decisions and were categorized into five themes defined by the Model of Trust. Similarly, a total of 60 statements on the factors that influence feedback receptivity were retained by the panel of medical residents and were categorized into five themes defined by the Ready, Willing, and Able model and the theory of self-regulated learning. Conclusion: Though not exhaustive, the key factors agreed upon by clinical educators and medical residents reflect the characteristics of entrustment-based supervision decisions and feedback receptivity across specialties. This study provides insight on an often overlooked issue of the paths to teaching and learning in competency-based residency training programs. Additionally, incorporation of the Delphi technique further adds to the existing literature and puts emphasis as an important tool that can be used in medical education to rigorously validate Q-statements and develop Q-samples in various specialties.

In-hospital mortality associated with necrotizing soft tissue infection due to Vibrio vulnificus: a matched-pair cohort study.

BACKGROUND: It remains unclear whether Vibrio vulnificus necrotizing soft tissue infection (NSTI) is associated with higher mortality compared with non-Vibrio NSTI. This study's objective was to compare outcomes including in-hospital mortality and prognosis between patients with V. vulnificus NSTI and those with non-Vibrio NSTI. METHOD: A retrospective 1:2 matched-pair cohort study of hospitalized patients with NSTI diagnosed by surgical finding was conducted in two tertiary hospitals in southern Taiwan between January 2015 and January 2020. In-hospital outcomes (mortality, length of stay) were compared between patients with and without V. vulnificus infection. We performed multiple imputation using chained equations followed by multivariable regression analyses fitted with generalized estimating equations to account for clustering within matched pairs. All-cause in-hospital mortality and length of stay during hospitalization were compared for NSTI patients with and without V. vulnificus. RESULT: A total of 135 patients were included, 45 in V. vulnificus NSTI group and 90 in non-Vibrio group. The V. vulnificus NSTI patients had higher mortality and longer hospital stays. Multivariable logistic regression analysis revealed that V. vulnificus NSTI was significantly associated with higher in-hospital mortality compared with non-Vibrio NSTI (adjusted odds ratio = 1.52; 95% confidence interval 1.36-1.70; p < 0.01). CONCLUSION: Vibrio vulnificus NSTI was associated with higher in-hospital mortality and longer hospital stay which may increase health care costs, suggesting that preventing V. vulnificus infection is essential.

Comparison of Surgical Outcomes and Predictors in Patients with Monomicrobial Necrotizing Fasciitis and Sepsis Caused by Vibrio vulnificus, Aeromonas hydrophila, and Aeromonas sobria.

Background: Monomicrobial necrotizing fasciitis caused by Vibrio vulnificus, Aeromonas hydrophila, and Aeromonas sobria are often associated with high mortality rates. The purpose of this study was to compare the independent predictors related to outcomes between Vibrio vulnificus and Aeromonas species necrotizing fasciitis. Patients and Methods: Monomicrobial necrotizing fasciitis caused by Vibrio vulnificus (60 patients) and Aeromonas species (31 patients) over an 11-year period were reviewed retrospectively. Differences in mortality, patient characteristics, clinical presentations, and laboratory data were compared between the Vibrio vulnificus and Aeromonas species groups, and between the death and the survival subgroups of patients with Aeromonas species. Results: Six patients in the Vibrio vulnificus group (10%) and 11 in the Aeromonas species group (32.3%) died. Fifty-nine patents had bacteremia and 16 patients died (27.1%). Patients who had Vibrio vulnificus had a higher incidence of bacteremia. The patients who had Aeromonas species presenting with bacteremia were significantly associated with death. The death subgroup of patients with Aeromonas necrotizing fasciitis had a higher incidence of bacteremia, higher counts of banded leukocytes, lower platelet counts, lower total lymphocyte counts, and lower serum albumin level than the survival subgroup. Conclusions: Monomicrobial necrotizing fasciitis caused by Aeromonas species was characterized by more fulminating and higher mortality than that of Vibrio vulnificus, even after early fasciotomy and third-generation cephalosporin antibiotic therapy. Those risk factors, such as bacteremia, shock, lower platelet counts, lower albumin levels, and antibiotic resistance were associated with mortality, which should alert clinicians to pay more attention to and aggressively treat those patients with Aeromonas and Vibrio necrotizing fasciitis.

Differentiating necrotizing soft tissue infections from cellulitis by soft tissue infectious fluid analysis: a pilot study.

BACKGROUND: We conducted this study to evaluate the characteristics of the infectious fluid in soft tissue infection and investigate the utility of the biochemical tests and Gram stain smear of the infectious fluid in distinguishing necrotizing soft tissue infection (NSTI) from cellulitis. METHODS: This retrospective cohort study was conducted in a tertiary care hospital in Taiwan. From April 2019 to October 2020, patients who were clinically suspected of NSTI with infectious fluid accumulation along the deep fascia and received successful ultrasound-guided aspiration were enrolled. Based on the final discharge diagnosis, the patients were divided into NSTI group, which was supported by the surgical pathology report, or cellulitis group. The t test method and Fisher's exact test were used to compare the difference between two groups. The receiver-operator characteristic (ROC) curves and area under the ROC curve (AUC) were used to evaluate the discriminating ability. RESULTS: Total twenty-five patients were enrolled, with 13 patients in NSTI group and 12 patients in cellulitis group. The statistical analysis showed lactate in fluid (AUC = 0.937) and LDH in fluid (AUC = 0.929) had outstanding discrimination. The optimal cut-off value of fluid in lactate was 69.6 mg/dL with corresponding sensitivity of 100% and specificity of 76.9%. The optimal cut-off value of fluid in LDH was 566 U/L with corresponding sensitivity of 83.3% and a specificity of 92.3%. In addition, albumin in fluid (AUC = 0.821), TP in fluid (AUC = 0.878) and pH in fluid (AUC = 0.858) also had excellent diagnostic accuracy for NSTI. The Gram stain smear revealed 50% bacteria present in NSTI group and all the following infectious fluid culture showed bacteria growth. CONCLUSIONS: The analysis of infectious fluid along the deep fascia might provide high diagnostic accuracy to differentiate NSTI from cellulitis.

"Glocalization" in medical education: A framework underlying implementing CBME in a local context.

BACKGROUND/PURPOSE: The implementation of competency-based medical education is a social construction process within a local and cultural context. However, little is known about the process of adaptation to different systems, known as "glocalization". We analyzed the documents in the development of a milestone project from adapting global standards into a local context and identified a framework underlying this process. METHODS: Taiwan Society of Emergency Medicine (TSEM) had developed learning milestones based on the ACGME's version through series of consensus methods including committee work, nominal group technique (NGT), and a modified Delphi method. We applied qualitative content analysis to characterize the evolution of the three versions of TSEM and the original ACGME milestones documents and to explore the meaning behind the differences revealed by the glocalization process. RESULTS: We found 48 differences between ACGME and TSEM milestones. Among these differences, one was made by committee work, 44 came from NGT, and 3 were from the modified Delphi process. Two themes and seven sub-themes emerged from the coding process to explain the contextualization process of the milestones. CONCLUSION: We identified a framework that incorporates local expression and local needs into the process called glocalization through which global models of competency-based standards could be optimally implemented in a local context with different systems and cultures.
