RESUMO

BACKGROUND: Sepsis is a life-threatening condition which may arise from infection in any organ system and requires early recognition and management. Healthcare professionals working in any specialty may need to manage patients with sepsis. Educating medical students about this condition may be an effective way to ensure all future doctors have sufficient ability to diagnose and treat septic patients. However, there is currently no consensus on what competencies medical students should achieve regarding sepsis recognition and treatment. This study aims to outline what sepsis-related competencies medical students should achieve by the end of their medical student training in both high or upper-middle incomes countries/regions and in low or lower-middle income countries/regions. METHODS: Two separate panels from high or upper-middle income and low or lower-middle income countries/regions participated in a Delphi method to suggest and rank sepsis competencies for medical students. Each panel consisted of 13-18 key stakeholders of medical education and doctors in specialties where sepsis is a common problem (both specialists and trainees). Panelists came from all continents, except Antarctica. RESULTS: The panels reached consensus on 38 essential sepsis competencies in low or lower-middle income countries/regions and 33 in high or upper-middle incomes countries/regions. These include competencies such as definition of sepsis and septic shock and urgency of antibiotic treatment. In the low or lower-middle income countries/regions group, consensus was also achieved for competencies ranked as very important, and was achieved in 4/5 competencies rated as moderately important. In the high or upper-middle incomes countries/regions group, consensus was achieved in 41/57 competencies rated as very important but only 6/11 competencies rated as moderately important. CONCLUSION: Medical schools should consider developing curricula to address essential competencies, as a minimum, but also consider addressing competencies rated as very or moderately important.

RESUMO

BACKGROUND: Two recent double-blind, randomized, controlled trials (RCTs) showed that oral steroids and nonsteroidal anti-inflammatory drugs have similar analgesic effectiveness for management of gout, but the trials had small sample sizes and other methodological limitations. OBJECTIVE: To compare the effectiveness and safety of oral prednisolone versus oral indomethacin in patients presenting to emergency departments (EDs) with acute gout. DESIGN: Multicenter, double-blind, randomized equivalence trial. Patients were randomly assigned (1:1 ratio) to receive either indomethacin or prednisolone. (ISRCTN registry number: ISRCTN45724113). SETTING: Four EDs in Hong Kong. PARTICIPANTS: 416 patients aged 18 years or older. MEASUREMENTS: Analgesic effectiveness was defined as changes in pain (at rest or with activity) greater than 13 mm on a 100-mm visual analogue scale. Outcomes were measured during the first 2 hours in the ED and from days 1 to 14. RESULTS: 376 patients completed the study. Equivalent and clinically significant within-group reductions in mean pain score were observed with indomethacin and prednisolone in the ED (approximately 10 mm [rest] and 20 mm [activity]) and from days 1 to 14 (approximately 25 mm [rest] and 45 mm [activity]). No major adverse events occurred during the study. During the ED phase, patients in the indomethacin group had more minor adverse events than those in the prednisolone group (19% vs. 6%; P < 0.001). During days 1 to 14, 37% of patients in each group had minor adverse events. LIMITATION: Diagnosis of gout was usually based on clinical criteria rather than examination of joint fluid. CONCLUSION: Oral prednisolone and indomethacin had similar analgesic effectiveness among patients with acute gout. Prednisolone is a safe, effective first-line option for treatment of acute gout.

RESUMO

BACKGROUND: The current evaluation of patients with chest pain presenting to an emergency department (ED) with suspected acute coronary syndrome (ACS) is a lengthy process involving serial measurements of troponin. OBJECTIVE: We aimed to validate the diagnostic accuracy of a Thrombolysis in Myocardial Infarction (TIMI) score with single high-sensitive cardiac troponin T (hs-cTnT) for early rule out of 30-day major adverse cardiac events (MACE), and to compare the TIMI score with combinations of heart-type fatty acid binding protein (H-FABP) and a modified HEART (history, electrocardiogram, age, risk factors, troponin) score. METHODS: We recruited 602 consecutive adult patients with chest pain and suspected ACS in the ED. Each patient had TIMI and HEART scores, and a point-of-care H-FABP test. RESULTS: MACE occurred in 42 (7.0%) patients within 30 days. A low risk for 30-day MACE was identified by a modified TIMI score of 0 in 65 (11%) patients, and by a HEART score ≤ 2 in 96 (16%) patients. No MACE occurred in these groups, giving both scores a sensitivity of 100% (95% confidence interval [CI] 91.6-100%), and specificity of 11.6% (95% CI 9.2-14.5%) and 17.1% (95% CI 14.2-20.5%), respectively. Use of combined TIMI and HEART scores improved the specificity further to 22.0% (95% CI 18.7-25.6%) without lowering sensitivity. Early H-FABP measurement > 7 µg/L had a sensitivity of 41.5% (95% CI 27.8-56.6%) and a specificity of 91.1% (95% CI 88.4-93.2%) for predicting 30-day MACE. CONCLUSIONS: A modified TIMI score of 0 or a HEART score of ≤ 2, incorporating a single hs-cTnT level, will identify patients with low risk of 30-day MACE for early discharge within 2 h of ED arrival.

RESUMO

INTRODUCTION: Early sepsis treatment in the emergency department (ED) is crucial to improve patient survival. Despite international promulgation, the uptake of the Surviving Sepsis Campaign (SSC) Hour-1 Bundle (lactate measurement, blood culture, broad-spectrum antibiotics, 30 mL/kg crystalloid for hypotension/lactate ≥4 mmol/L and vasopressors for hypotension during/after fluid resuscitation within 1 hour of sepsis recognition) is low across healthcare settings. Delays in sepsis recognition and a lack of high-quality evidence hinder its implementation. We propose a novel sepsis care model (National Early Warning Score, NEWS-1 care), in which the SSC Hour-1 Bundle is triggered objectively by a high NEWS-2 (≥5). This study aims to determine the feasibility of a full-scale type 1 hybrid effectiveness-implementation trial on the NEWS-1 care in multiple EDs. METHODS AND ANALYSIS: We will conduct a pilot type 1 hybrid trial and prospectively recruit 200 patients from 4 public EDs in Hong Kong cluster randomised in a stepped wedge design over 10 months. All study sites will start with an initial period of standard care and switch in random order at 2-month intervals to the NEWS-1 care unidirectionally. The implementation evaluation will employ mixed methods guided by the Reach, Effectiveness, Adoption, Implementation and Maintenance framework, which includes qualitative and quantitative data from focus group interviews, staff survey and clinical record reviews. We will analyse the 14 feasibility outcomes as progression criteria to a full-scale trial, including trial acceptability to patients and staff, patient and staff recruitment rates, accuracy of sepsis screening, protocol adherence, accessibility to follow-up data, safety and preliminary clinical impacts of the NEWS1 care, using descriptive statistics. ETHICS AND DISSEMINATION: The institutional review boards of all study sites approved this study. This study will establish the feasibility of a full-scale hybrid trial. We will disseminate the findings through peer-reviewed publications, conference presentations and educational activities. TRIAL REGISTRATION NUMBER: NCT05731349.

RESUMO

PURPOSE: Hong Kong (HK) trauma registries have been using the Trauma and Injury Severity Score (TRISS) for audit and benchmarking since their introduction in 2000. We compare the mortality prediction model using TRISS and Revised Injury Severity Classification, version II (RISC II) for trauma centre patients in HK. METHODS: This was a retrospective cohort study with all five trauma centres in HK. Adult trauma patients with Injury Severity Score (ISS) > 15 suffering from blunt injuries from January 2013 to December 2015 were included. TRISS models using the US and local coefficients were compared with the RISC II model. The primary outcome was 30-day mortality and the area under the receiver operating characteristic curve (AUC) for tested models. RESULTS: 1840 patients were included, of whom 1236/1840 (67%) were male. Median age was 59 years and median ISS was 25. Low falls were the most common mechanism of injury. The 30-day mortality was 23%. RISC II yielded a superior AUC of 0.896, compared with the TRISS models (MTOS: 0.848; PATOS: 0.839; HK: 0.858). Prespecified subgroup analyses showed that all the models performed worse for age ≥ 70, ASA ≥ III, and low falls. RISC II had a higher AUC compared with the TRISS models in all subgroups, although not statistically significant. CONCLUSION: RISC II was superior to TRISS in predicting the 30-day mortality for Hong Kong adult blunt major trauma patients. RISC II may be useful when performing future audit or benchmarking exercises for trauma in Hong Kong.

RESUMO

PURPOSE: Trauma remains a major cause of morbidity and disability worldwide; however, reliable data on the health status of an urban Asian population after injury are scarce. The aim was to evaluate 1-year post-trauma return to work (RTW) status in Hong Kong. METHODS: This was a prospective, multi-center cohort study involving four regional trauma centers from 2017 to 2019 in Hong Kong. Participants included adult patients entered into the trauma registry who were working or seeking employment at the time of injury. The primary outcome was the RTW status up to 1 year. The Extended Glasgow Outcome Scale, 12-item Short Form (SF-12) survey and EQ5D were also obtained during 1-, 3-, 6-, 9-, and 12-month follow-ups. Multivariable Cox proportional hazards regression analysis was used for analysis. RESULTS: Six hundred and seven of the 1115 (54%) recruited patients had RTW during the first year after injury. Lower physical requirements (p = 0.003, HR 1.51) in pre-injury job nature, higher educational levels (p < 0.001, HR 1.95), non-work-related injuries (p < 0.001, HR 1.85), shorter hospital length of stay (p = 0.007, HR 0.98), no requirement for surgery (p = 0.006, HR 1.34), and patients who could be discharged home (p = 0.006, HR 1.43) were associated with RTW within 12 months post-injury. In addition, 1-month outcomes including extended Glasgow Outcome Scale ≥ 6 (p = 0.001, HR 7.34), higher mean SF-12 physical component summary (p = 0.002, HR 1.02) and mental component summary (p < 0.001, HR 1.03), and higher EQ5D health index (p = 0.018, HR 2.14) were strongly associated with RTW. CONCLUSIONS: We have identified factors associated with failure to RTW during the first year following in Hong Kong including socioeconomic factors, injury factors and treatment-related factors and 1-month outcomes. Future studies should focus on the interventions that can impact on RTW outcomes. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03219424.

RESUMO

BACKGROUND: Trauma remains a leading cause of death and effective trauma management within a well-developed trauma system has been shown to reduce morbidity and mortality. A trauma registry, as an integral part of a mature trauma system, can be used to monitor the quality of trauma care and to provide a means to compare local versus international standards. Hong Kong and Germany both have highly developed health care services. We compared the performance of trauma systems including outcomes among major trauma victims (ISS > 15) over a 3-year period (2013-2015) in both settings using trauma registry data. METHODS: This study was a retrospective analysis of prospectively collected data from trauma registries in Hong Kong and Germany. Data from 01/2013 to 12/2015 were extracted from the trauma registries of the five trauma centers in Hong Kong and the TraumaRegister DGU® (TR-DGU). The study cohort included adults (≥ 18 years) with major trauma (ISS > 15). Data related to patient characteristics, nature of the injury, prognostic parameters to calculate the RISC II score, outcomes and clinical management were collected and compared. RESULTS: Datasets from 1,864 Hong Kong and 10,952 German trauma victims were retrieved from respective trauma registries. The unadjusted mortality in Hong Kong (22.4%) was higher compared to Germany (19.2%); the difference between observed and expected mortality was higher in Hong Kong (+ 2.7%) than in Germany (- 0.5%). The standardized mortality ratio (SMR) in Hong Kong and Germany were 1.138 (95% CI 1.033-1.252) and 0.974 (95% CI 0.933-1.016), respectively, and the adjusted death rate in Hong Kong was significantly higher compared to the calculated RISC II data. However, patients in Hong Kong were significantly older, had more pre-trauma co-morbidities, more head injuries, shorter hospital and ICU stays and lower ICU admission rates. CONCLUSION: Hong Kong had a higher mortality rate and a statistically significantly higher standardized mortality ratio (SMR) after RISC II adjustment. However, multiple differences existed between trauma systems and patient characteristics.

RESUMO

Syncope is a sudden and transient loss of consciousness and postural tone, with spontaneous recovery without medical intervention. It accounts for 1.0% to 1.5% of emergency department (ED) visits and up to 6% of hospital admissions. Vasovagal syncope may be the cause of syncope in 21% to 40% of cases. A 53-year-old Chinese woman was brought to the ED by ambulance after a near-syncope episode while performing gentle morning exercises. She was hypotensive and bradycardic in the ambulance. Upon arrival at the ED, her blood pressure was 89/61 mmHg. The use of a Doppler cardiac output monitor readily demonstrated that the patient's systemic vascular resistance was reduced, with cardiac output at the lower limit of the normal range. These hemodynamic data were useful in supporting the diagnosis of vasovagal syncope; they helped in the risk stratification of our patient with syncope, and guided the management and subsequent disposition decision.

RESUMO

BACKGROUND: The present study aimed to investigate and compare plasma concentrations of miR-124-3p and miR-16 as diagnostic markers in acute stroke. METHODS: miR-124-3p and miR-16 concentrations in 93 stroke patients were analyzed using real-time polymerase chain reaction. The primary outcome was the differentiation of hemorrhagic and ischemic stroke. RESULTS: Of 93 patients, 74 (79.6%) were diagnosed as ischemic stroke (IS) and 19 (20.4%) were diagnosed as hemorrhagic stroke (HS). Median plasma 124-3p concentrations taken within 24h of symptom onset were higher in HS patients than that in IS patients (3.8×10(5) vs 2.0×10(5) copies/ml plasma, p=0.0109), while median miR-16 concentration in IS patients were higher than that in HS patients (1.6×10(9) vs 1.3×10(9) copies/ml plasma, p=0.0399). The odds ratio (OR) for discriminating HS and IS with miR-124-3p and miR-16 was 5.37 and 9.75 respectively. CONCLUSION: Both miR-124-3p and miR-16 are diagnostic markers to discriminate HS and IS.

RESUMO

BACKGROUND: Patients sometimes present to the Emergency Department (ED) for reinsertion of nasogastric tubes (NGT) because of tube dislodgement. They usually need to wait for a long time to see a doctor before the NGT can be reinserted. This study aimed at investigating the feasibility of nurse initiated NGT insertion for these patients in order to improve patient outcome. METHODS: This is a prospective randomised controlled trial. Patients requiring NGT reinsertion were randomised to receive treatment by either nurse initiated reinsertion of NGT (NIRNGT) or the standard NGT insertion protocol. Questionnaires were given to both groups of patients, relatives and ED nurses afterwards. Outcome measures included door-to-treatment time, total length of stay (LoS) in the ED and the satisfaction of patients, relatives and nurses. RESULTS: Twenty-two patients were recruited to the study and randomised: 12 in the standard NGT insertion protocol and 10 in the NIRNGT protocol. The door-to-treatment time of the NIRNGT group (mean=45.6 min) was significantly shorter than the standard NGT insertion group (mean=123.08 min; p=0.003). No statistically significant difference was detected between the total ED LoS (p=0.575). Patients, relatives and nurses were generally satisfied with the new treatment protocol. CONCLUSION: Patients can undergo NGT reinsertion significantly faster by adopting a nurse initiated reinsertion of NGT (NIRNGT) protocol.

RESUMO

OBJECTIVES: We investigated the relationships of biomarkers of various pathophysiologic pathways including high-sensitivity C-reactive protein (hs-CRP), lipocalin-2 (LCN2), myeloperoxidase (MPO) and matrix metalloproteinases 9 (MMP9) with mortality in stroke patients. DESIGN AND METHODS: hs-CRP, LCN2 and MPO concentrations in 92 patients were determined using enzyme-linked immunosorbent assays. MMP9 mRNA concentrations were determined using real-time quantitative reverse transcription-polymerase chain reaction. RESULTS: Twelve patients (13.0%) died at 6 months and 34 patients (37.0%) died at 5 years. The independent predictors for 6-month mortality were hs-CRP (adjusted OR=16.0) and LCN2 (adjusted OR=16.9), while for 5-year mortality was hs-CRP (adjusted OR=5.56). For patients with hs-CRP >3.4 mg/L, an increase in LCN2 was associated with 2.5-fold higher 6-month mortality, while an increase in normalized MMP9 mRNA was associated with 5.8-fold higher 6-month and 1.5-fold higher 5-year mortality. CONCLUSION: hs-CRP was the most significant independent predictor of both short- and long-term mortality after stroke, with LCN2 and MMP9 mRNA each adding further to the risk stratification.
