Accuracy of Dysphagia Standard Assessment (DSA®) bedside screening test: a flowchart for patient eligibility.

BACKGROUND: Oropharyngeal dysphagia (OD) screening tests have improved patient management; however, the complex applicability and high percentage of false negatives do not allow these tests to be considered completely reliable if not supported by an instrumental investigation. The aim of the present study is to evaluate an OD screening test, the Dysphagia Standard Assessment (DSA®) with different volumes and viscosities. MATERIALS AND METHODS: Prospective study of 72 patients evaluated for suspected OD through a double-blind methodology conducted by two operators. All patients underwent fiberoptic endoscopic evaluation of swallowing (FEES) as a reference test and a separate DSA® test. DSA® was performed by administering boluses with different viscosities, with the signal of interruption of the test being: onset of the cough reflex, wet voice after swallowing, and/or desaturation of O2 ≥ 5%. The Penetration-Aspiration Scale (PAS) was evaluated by FEES. The cut-off identified to diagnose OD was PAS ≥ 3. RESULTS: The test showed an accuracy of 82%, a sensitivity of 0.93 (95% C.I. 0.84-0.97), and a specificity of 0.78 (95% C.I. 0.67-0.87); positive predictive value 0.55 (95% C.I. 0.43-0.67); negative predictive value 0.97 (95% C.I. 0.90-0.99), positive likelihood ratio 4.37 (95% C.I. 3.6-5.2); likelihood negative ratio 0.08 (95% C.I. 0.06-0.09). CONCLUSIONS: According to the preliminary results, the test showed good outcomes in determining the presence or absence of OD with a wide spectrum of applicability with some limitations that could be overcome by the selection of a target population. For this reason, a flowchart to address patient eligibility was developed.

Analysis of road traffic accidents involving standing electric scooters reported in newspapers in Italy.

OBJECTIVE: As the use of electric scooters increased in Italy in the last years, we aimed to estimate the burden of accidents caused by this micro-mobility vehicle and identify characteristics, severity, and type of injuries. METHODS: We conducted a case series analysis of news reports about electric scooter crashes occurring in Italy from January 1, 2019 to September 30, 2020. Events were included when a road traffic accident involved an electric scooter and caused damages or injuries to the driver or others. RESULTS: We identified 96 road accidents involving electric scooters in Italy. The mean age of patients was 30 ± 16 years, and 79% (n = 71/90) were male. Of the 96 patients, only two (2%) were driving an electric scooter with a helmet, and three (3%) were driving while intoxicated. In 68% (n = 62/94) of cases, the incident was caused by a collision with another vehicle or a pedestrian, and 30% (n = 18/96) were transported with life-threatening injuries to the emergency department. In 15% (n = 14/96), the emergency medical service physician was dispatched to the scene. Head trauma was the most common injury (60%, n = 32/53). Patients who had life-threatening conditions were more likely to have head trauma than those who did not (82% [n = 9/11] vs. 55% [n = 23/42], P = 0.10). Polytrauma was significantly more common in patients with life-threatening conditions than in patients with no life-threatening conditions (36% [n = 4/11] vs. 5% [n = 2/42], P < 0.01). Fifteen percent of patients (n = 12/81) were admitted to the intensive care unit; only one death was reported. CONCLUSION: Road traffic accidents involving electric scooters often result in serious injuries, including head trauma and polytrauma, necessitating the involvement of an emergency medical service physician and intensive care unit admission in a non-negligible percentage of instances.

Impact of COVID-19 Pandemic on Out-of-Hospital Cardiac Arrest System-of-Care: A Systematic Review and Meta-Analysis.

Introduction: COVID-19 pandemic overwhelmed healthcare systems and diverted resources allocated for other conditions. This systematic review and meta-analysis aimed to analyse how the pandemic impacted the system-of-care of out-of-hospital cardiac arrest.Methods: We searched PubMed and Embase up to May 31, 2021, for studies comparing out-of-hospital cardiac arrests that occurred during the COVID-19 pandemic versus a non-pandemic period. Survival at hospital discharge or at 30 days was the primary outcome.Results: We included 24 studies for a total of 75,952 patients. Out-of-hospital cardiac arrests during COVID-19 pandemic had lower survival (19 studies; 603/11,666 [5.2%] vs. 1320/17,174 [7.7%]; OR = 0.54; 95% CI, 0.44-0.65; P = 0.001) and return of spontaneous circulation (4370/24353 [18%] vs. 7401/34510 [21%]; OR = 0.64; 95% CI, 0.55-0.75; P < 0.001) compared with non-pandemic periods. Ambulance response times (10.1 vs 9.0 minutes, MD = 1.01; 95% CI, 0.59-1.42; P < 0.001) and non-shockable rhythms (18,242/21,665 [84%] vs. 19,971/24,817 [81%]; OR = 1.27; 95% CI, 1.10-1.46; P < 0.001) increased. Use of supraglottic airways devices increased (2853/7645 [37%] vs. 2043/17521 [12%]; OR = 1.97; 95% CI, 1.42-2.74; P < 0.001).Conclusions: The COVID-19 pandemic affected the system-of-care of out-of-hospital cardiac arrest, and patients had worse short-term outcomes compared to pre-pandemic periods. Advanced airway management strategy shifted from endotracheal intubation to supraglottic airway devices. REVIEW REGISTRATION: PROSPERO CRD42021250339.

Life-threatening ventricular tachyarrhythmias in the cardiology department: Implications for appropriate prescription of telemetry monitoring.

BACKGROUND: in-hospital life-threatening ventricular arrhythmias (LT-VA) may complicate the course of cardiovascular patients. We aimed to assess the incidence, circumstances, determinants, and outcome of in-hospital LT-VA in order to help clinicians in prescribing appropriate levels of monitoring. METHODS: the study population consisted of all 10,741 consecutive patients (65 ± 15 years, 67.7% males) admitted to a cardiology department in 2009-2014. Terminally ill patients and those with primary arrhythmia diagnosis were excluded. The composite end-point included sudden arrhythmic death, ventricular fibrillation, unstable ventricular tachycardia and appropriate ICD shock unrelated to invasive interventions. RESULTS: the incidence of LT-VA was 0.6%, with no differences regarding age, gender and primary diagnosis of coronary artery disease between patients with and without LT-VA. The incidence of LT-VA was significantly higher (1.2% versus 0.1%, p<0.001) among urgent compared with elective admissions and among patients with left ventricular ejection fraction (LV-EF) <45% (1.7% versus 0.2%, p<0.001). At multivariable analysis, urgent admission and LV-EF <45%, but not primary diagnosis of coronary artery disease, remained independent predictors of LT-VA. At the time of the event, 97.1% fulfilled either class I or class II indications for telemetry monitoring according to the American Heart Association guidelines. Survival to discharge with good neurological status was 70.6%. CONCLUSIONS: acutely ill patients with heart failure and LV systolic dysfunction showed the highest rate of LT-VAs, regardless of the underlying cardiac disease (ischemic or non-ischemic). Current guidelines demonstrated high sensitivity in identifying patients at risk. These findings may favor proper utilization of telemetry monitoring resources.

Surviving out-of-hospital cardiac arrest: just a matter of defibrillators?

Out-of-hospital sudden cardiac arrest (OHCA) is a leading cause of death all over the world. Although the outcome of OHCA resulting from 'nonshockable' rhythms (asystole and pulseless electrical activity) is poor regardless of resuscitation efforts, 'shockable' rhythms such as ventricular tachycardia or fibrillation may carry a good prognosis if early defibrillation is performed. At present, simplified cardiopulmonary resuscitation techniques (hands-only cardiopulmonary resuscitation) and automated external defibrillators (AEDs) offer lay people the possibility to provide lifesaving treatment to OHCA victims in the critical minutes before the arrival of the emergency medical system. Programs aimed at increasing provision of cardiopulmonary resuscitation and use of AEDs by lay people have been set up in different countries, including Italy, and have contributed to improve survival rates. However, success of these programs critically depends on appropriate planning and design, and on cultural predisposition of witnesses to undertake immediate measures of resuscitation in the case of OHCA. Placement of a large number of AEDs may carry high costs and little benefits if it is uncoordinated and not preceded by educational campaigns to spread widely the 'culture of resuscitation' in the population.

Thirty and ninety days mortality predictive value of admission and in-hospital procalcitonin and mid-regional pro-adrenomedullin testing in patients with dyspnea. Results from the VERyfing DYspnea trial.

INTRODUCTION: Mid-regional pro-atrial natriuretic peptide (MR-proANP), procalcitonin (PCT), and mid-regional pro-adrenomedullin (MR-proADM) demonstrated usefulness for management of emergency department patients with dyspnea. METHODS: To evaluate in patients with dyspnea, the prognostic value for 30 and 90 days mortality and readmission of PCT, MR-proADM, and MR-proANP, a multicenter prospective study was performed evaluating biomarkers at admission, 24 and 72 hours after admission. Based on final diagnosis, patients were divided into acute heart failure (AHF), primary lung diseases, or both (AHF + NO AHF). RESULTS: Five hundred one patients were enrolled. Procalcitonin and MR-proADM values at admission and at 72 hours were significantly (P < .001) predictive for 30-day mortality: baseline PCT with an area under the curve (AUC) of 0.70 and PCT at 72 hours with an AUC of 0.61; baseline MR-proADM with an AUC of 0.62 and MR-proADM at 72 hours with an AUC of 0.68. As for 90-day mortality, both PCT and MR-proADM baseline and 72 hours values showed a significant (P < .0001) predictive ability: baseline PCT with an AUC of 0.73 and 72 hours PCT with an AUC of 0.64; baseline MR-proADM with an AUC of 0.66 and 72 hours MR-proADM with an AUC of 0.71. In AHF, group biomarkers predicted rehospitalization and mortality at 90 days, whereas in AHF + NO AHF group, they predict mortality at 30 and 90 days. CONCLUSIONS: In patients admitted for dyspnea, assessment of PCT plus MR-proADM improves risk stratification and management. Combined use of biomarkers is able to predict in the total cohort both rehospitalization and death at 30 and 90 days.
