External validation of the "deformity, edema, and pain in pronation" model for predicting wrist fractures

BACKGROUND

The aim of this study is to externally validate the "Deformity, Edema, and Pain in Pronation" model, which determines the necessity for radiography in patients with wrist trauma.

METHODS

This prospective, cross-sectional study was performed in a tertiary emergency department (ED). All patients admitted to the ED with wrist trauma aged 18 years and older were included in the study. Patients who did not have acute and blunt wrist trauma, those who could not be fully examined due to various reasons, and patients who did not wish to participate were excluded. Each patient was examined by their responsible physician, and imaging tests were requested based on the indications. All radiographic images were evaluated by an orthopedic surgeon who was blinded to the clinical information. This evaluation was accepted as the standard reference for diagnosing fractures.

RESULTS

391 patients were included in the study. 170 patients (43.5%) had at least one fracture. The sensitivity and specificity of the model formed in our study in predicting wrist fractures were 98.77% (95% CI: 95.61-99.85) and 27.60% (95% CI 21.82-34.00), respectively. The area under the receiver operating characteristic curve (AUC) on external validation of the model was 0.878 (p < 0.001; 95% CI: 0.844-0.913). With the practice of this rule, there would be a 16% decrease in X-ray imaging request, while only 0.5% patients would have missed inoperable fractures.

CONCLUSION

The "deformity, edema, and pain in pronation" model is a reliable and practical clinical decision rule for determining the necessity of radiography in wrist trauma.

Comparing TIMI, HEART, and GRACE Risk Scores to Predict Angiographic Severity of Coronary Artery Disease and 30-Day Major Adverse Cardiac Events in Emergency Department Patients with NSTEACS

BACKGROUND

Acute coronary syndromes (ACS) are hard to diagnose because their clinical presentation is broad. Current guidelines suggest early clinical risk stratification to the optimal site of care. The aim of this study was to investigate the ability of Thrombolysis in Myocardial Infarction (TIMI); History, Electrocardiogram, Age, Risk Factors, Troponin (HEART); and Global Registry of Acute Coronary Events (GRACE) risk scores to predict the development of major adverse cardiac events (MACE) and the angiographic severity of coronary artery disease (CAD) in patients diagnosed with non-ST-segment elevation acute coronary syndrome (NSTEACS) in the emergency department (ED). In addition, independent variables associated with the development of MACE were also examined.

METHODS

This study is a prospective, observational, single-center study. All patients over 18 years of age who were planned to be hospitalized for pre-diagnosed NSTEACS (NSTEMI + UAP) were included in the study consecutively. Patients' demographic information and all variables necessary for calculating risk scores (TIMI, HEART, and GRACE) were recorded. Two experienced cardiologists evaluated all coronary angiograms and calculated the Gensini score.

RESULTS

The median age was 60 (IQR: 18) years, and 220 (61.6%) were male of the 357 patients included in the study. In this study, 91 MACE (52 percutaneous coronary interventions [PCI], 28 coronary artery bypass graft [CABG], three cerebrovascular disease [CVD], and eight deaths) occurred. The 30-day MACE rate was 25.5%. The low-risk group constituted 40.0%, 1.4%, and 68.0% of the population, respectively, in TIMI, HEART, and GRACE scores. Multiple logistic regression models for predicting MACE, age (P = .005), mean arterial pressure (MAP; P = .015), and High-Sensitive Troponin I (P = .004) were statistically significant.

CONCLUSION

The ability of the GRACE, HEART, and TIMI risk scores to predict severe CAD in patients with NSTEACS is similar. In patients with NSTEACS, the HEART and GRACE risk scores can better predict the development of MACE than the TIMI risk score. When low-risk groups are evaluated according to the three risk scores, the HEART score is more reliable to exclude the diagnosis of NSTEACS.

Occupational accidents of emergency medicine residents in Turkey

Objectives. Healthcare workers face many biologic, chemical, physical and psychosocial hazards and risks in their work environment. Our research aimed to examine the types and frequency of occupational accidents, their notification status and predisposing factors to which emergency medicine residents (EMRs) were exposed in the last 12 months in Turkey. Methods. This research is a national, multicenter, online descriptive survey study. Participants' descriptive features, characteristics of occupational accidents they were exposed to in the last 12 months and their use status of personal protective equipment (PPE) were examined. Results. We found that 215 EMRs were exposed to 1919 occupational accidents in the last 12 months, and only 287 of these accidents were reported. All participants had at least one occupational accident in the previous 12 months. PPE was not used in 37.9 and 44% of biologic and chemical transmission accidents, respectively. The PPE use frequency of the EMRs in necessary situations for examination gloves, surgical masks, respirators, goggles, gowns and face shields was 60, 19, 19, 8, 15 and 4%, respectively. Conclusion. The actual number of occupational accidents was determined to be considerably higher than those reported. PPE use habits of EMRs were less than they should be.
