Admission criteria for a cardiovascular short stay unit: a retrospective analysis on a pilot unit.

Rapid intensive observation (RIO) units have been created to guarantee high standards of care in a sustainable health-care system. Within short stay units (SSUs), which are a subgroup of RIOs, only rapidly manageable patients should be admitted. Physicians are unable to predict the length of stay (LOS) as objective criteria to make such a prediction are missing. A retrospective observational study was carried out to identify the objective criteria for admission within a cardiovascular care-oriented SSU. Over a period of 317 days, 340 patients (age 69.4 ± 14.7 years) were admitted to a pilot SSU within our internal medicine department. The most frequent diagnoses were chest pain (45.9%), syncope (12.9%), and supraventricular arrhythmias (11.2%). The median LOS was 4 days (quartile 1:3; quartile 3:7). Predictors of LOS ≤ 96 h were age < 80, hemoglobin > 115 g/L, estimated glomerular filtration rate > 45 mL/min/1.73 m2, Charlson Comorbidity Index < 3, Barthel Index > 40, diagnosis of chest pain, syncope, supraventricular arrhythmias, or acute heart failure. The HEART (history, ECG, age, risk factors, troponin) score was found to be excellent in risk stratification of patients admitted for chest pain. Blood tests and anamnestic variables can be used to predict the LOS and thus SSU admission. The HEART score may help in the classification of patients with chest pain admitted to an SSU.

Violence against health workers: findings from three emergency departments in the teaching hospital of Padua, Italy.

Emergency departments (EDs) are high-risk places for Workplace Violence (WPV). In Italy, this phenomenon is scarcely investigated. The aim of this study is to evaluate the incidence, experiencing and perception of WPV in the general ED (GED), paediatric ED (PED) and obstetric-gynaecological ED (OGED) of the teaching hospital Azienda Ospedaliera in Padua (AOP). We led a cross-sectional study among the GED, OGED and PED staffs, submitting an anonymous questionnaire, regarding personal information, verbal and physical aggression experiences, risk factors and proposals for corrective actions. Our sample consists of 73 people from GED, 45 from OGED and 53 from PED. Aggressions are common. Verbal aggressions are almost never recorded, even in the case of physical aggressions, 41% did not signal the event. Both in GED and in OGED, most of the staff (68.9% and 75.0%, respectively) underwent aggression by neither psychiatric nor substance abuser patients (PSAPs). Physical aggressions are more common in GED than in OGED and in PED; most of professionals were assaulted by PSAPs. In all EDs, verbal or physical assault has been lived through by anger, resignation or fear, rarely by indifference. Professionals think there are structural characteristics and risk factors that could be corrected. They do not know how to manage assaults and would deem it useful training meetings with experts. Our results regarding how staff perceive and experience violence in the ED concern a local situation, that nevertheless reflect current evidence about the topic of WPV which plagues EDs across the globe.

Relationship between anatomical sites and severity of the lesions and use of alcohol and psychotropic substances in traumatized drivers admitted to the Emergency Department of Padua, Italy.

INTRODUCTION: Driving under the influence of alcohol and/or psychoactive substances increases the risk of road accidents, but it is controversial whether this affects site and severity of injuries. MATERIAL AND METHODS: We search for alcohol, cannabinoids, cocaine, benzodiazepines, opioids, methadone, amphetamines and barbiturates in biological fluids of 1764 traumatized drivers admitted to the Emergency Department (ED) of Padua between 2010 and 2014. RESULTS: We note correlation between alcohol and benzodiazepines and admission in ICU and between all the intoxications and the reserved prognosis. The sites of injuries were: head (37.13%), maxillofacial (8.33%), spinal column (44.67%), thoracic (15.31%), abdominal (5%), pelvic (2.55%) and limb traumas (23.58%). We observed a correlation between head trauma (p < 0.0001), maxillofacial trauma (p = 0.0418), thoracic trauma (p = 0.0215), pelvic trauma (p = 0.0008), spinal column trauma (p < 0.0001) and the totality of the intoxication and an association between benzodiazepines and thoracic and pelvic trauma. CONCLUSIONS: Alcohol and benzodiazepines intoxication increases the risk of reserved prognosis and admission in ICU; benzodiazepines intoxication correlates with thoracic and pelvic trauma.

Changes in Accident & Emergency Visits and Return Visits in Relation to the Enforcement of Daylight Saving Time and Photoperiod.

Daylight saving time (DST) is a source of circadian disruption impinging on millions of people every year. Our aim was to assess modifications, if any, in the number, type, and outcome of Accident & Emergency (A&E) visits/return visits over the DST months. The study included 366,527 visits and 84,380 return visits to the A&E of Padova hospital (Northern Italy) over 3 periods between the years 2007 and 2016: period 1 (2 weeks prior to DST to 19 weeks after), period 2 (2 weeks prior to the return to "winter time" to 4 weeks after), and period 3 (5 consecutive non-DST weeks). For each A&E visit/return visit, information was obtained on triage severity code, main medical complaint, and outcome. Data were aggregated by day, cumulated over the years, and analyzed by generalized Poisson models. Generalized additive models for Poisson data were then used to include photoperiod as an additional covariate. An increase in A&E visits and return visits (mostly white codes, resulting in discharges) was observed a few weeks after the enforcement of DST and was significant over most weeks of period 1 (increase of ≈30 [2.8%] visits and ≈25 [10%] return visits per week per year). After the return to winter time, a decrease in absolute number of return visits was observed (mostly white codes, resulting in discharges), which was significant at weeks 3 and 4 of period 2 (decrease of ≅25 [10%] return visits per week per year). When photoperiod was taken into account, changes in A&E visits (and related white codes/discharges) were no longer significant, while changes in return visits (and related white codes/discharges) were still significant. In conclusion, changes in A&E visits/return visits were observed in relation to both DST and photoperiod, which are worthy of further study and could lead to modifications in A&E organization/staffing.

A Social Media-Based Acute Alcohol Consumption Behavior (NekNomination): Case Series in Italian Emergency Departments.

BACKGROUND: NekNomination, also known as NekNominate, Neck and Nominate, or Neck Nomination, is a social network-based drinking game which is thought to have originated in Australia and spread all over the world between 2013 and 2014. Individuals record videos of themselves while rapidly drinking excessive quantities of alcoholic drinks (necking) and then nominate friends to outdo them within 24 hours; the videos are then posted on social media such as Facebook or YouTube. The consequences of this drinking game have been very dangerous; at least 5 people under age 30 years have died after drinking deadly cocktails, and many others have suffered from alcohol intoxication. OBJECTIVE: The goal of the research is to evaluate data about clinically important acute alcohol intoxication among teenagers and young adults and inform and educate the general public, especially parents, teachers, and health workers, about the spreading craze of dangerous Internet-related behavior among today's teenagers and young people up to the age of 23 years. METHODS: Patients aged 15 to 23 years with acute alcohol intoxication who came to the emergency department (ED) of 2 major hospitals in Italy from January 1, 2011, to June 30, 2014, were included in this study. Data were retrieved from prehospital and intrahospital medical records and included personal information, methods of intoxication, triage color code, date and time of access to the ED, any relevant signs and symptoms, blood alcohol concentration, and diagnosis at discharge. RESULTS: A total of 450 young patients (male 277/450, 61.5%, female 173/450, 38.5%; age 15 to 16 years 15/450, 3.3%, age 17 to 18 years 184/450, 40.9%, age 19 to 23 years 251/450, 55.8%) were recruited. The causes of intoxication were happy hour, binge drinking, NekNominate, eyeballing, other alcoholic games, or a mix of them. Happy hour was found to be more common among the older patients, whereas NekNominate accounted for almost half of the youngest group of hospitalizations. Eyeballing occurred in 1.6% (7/450) of cases; binge drinking and other alcoholic games caused 23.3% (105/450) and 23.8% (107/450) of hospitalizations, respectively. On admission, 44.2% (199/450) of patients were assigned a red or yellow color code requiring immediate medical attention; about 14% of them required additional medical assistance (after being in the ED) or hospitalization, some in semi-intensive care units. CONCLUSIONS: Our study shows that the increased numbers of hospitalizations due to alcohol intoxication in the adolescent age group, as a consequence of NekNominate or other drinking games, is alarming and represents a serious public health issue. The potential markers of improper use of social networks must be clearly identified, including categories at risk of alcohol abuse, in order to develop intervention and prevention strategies in terms of education and awareness, which may help in averting potentially fatal episodes.

The Rise of New Alcoholic Games Among Adolescents and the Consequences in the Emergency Department: Observational Retrospective Study.

BACKGROUND: The links between the internet and teenager behavior are difficult situations to control and may lead to the development of new and excessive methods of drinking alcohol during alcoholic games. Findings indicate that reported cases are very useful sources for better understanding of alcoholic games, yielding successful measures promoting health among adolescents. Admittance of adolescents to hospital emergency departments (EDs) after consumption of excessive amounts of alcohol has become the norm in developed countries. The harmful effects of acute alcohol abuse are reported in this paper. OBJECTIVE: The aim of this work was to investigate the close connections between new drinking behaviors among adolescents and study the increase in new alcoholic games, together with the challenges that cause acute alcohol intoxication, the influence of the internet and social networks, and their consequences for public health services. METHODS: Data came from prehospital and intrahospital admissions attributable to alcohol consumption. From 2013 to 2015, 3742 patients were admitted to EDs due to acute alcohol intoxication: 830 of them were aged 15 to 30 years, and 225 were adolescents and young adults between 15 and 20 years who had been playing alcoholic games. Retrospectively, diagnostic data associated with extrahospital anamneses were selected by one of the hospital management information systems, Qlik. As a result of our previous experience, questionnaires and face-to-face interviews were performed at a later stage, when a clinical audit for intoxicated adolescent patients was described, with the overall goal of establishing a potential methodological workflow and adding important information to research carried out so far. RESULTS: Between 2013 and 2015, 830 young patients aged 15 to 30 years were admitted to EDs for acute alcohol intoxication. About 20% (166/830) of the sample confirmed that they had drunk more than 5 alcoholic units within 2 hours twice during the past 30 days as a result of binge drinking. Referring to new alcoholic games, 41% of the sample stated that they knew what neknomination is and also that at least one of their friends had accepted this challenge, describing symptoms such as vomiting, headache, altered behavior, increased talkativeness, and sociability. The median value of the weighted average cost of the diagnosis-related group relating to interventions provided by hospitals was the same for both genders, €46,091 (US $56,497; minimum €17,349 and maximum €46,091). CONCLUSIONS: Drinking games encourage young people to consume large quantities of alcohol within a short period of time putting them at risk of alcohol poisoning, which can potentially lead to accidental injuries, unsafe sex, suicide, sexual assault, and traffic accidents. The spread of these games through the internet and social networks is becoming a serious health problem facing physicians and medical professionals every day, especially in the ED; for this reason, it is necessary to be aware of the risks represented by such behaviors in order to recognize and identify preliminary symptoms and develop useful prevention programs. The strategic role of emergency services is to monitor and define the problem right from the start in order to control the epidemic, support planning, coordinate the delivery of assistance in the emergency phase, and provide medical education. Hospital-based interdisciplinary health care researchers collected specific data on hazardous drinking practices linked to evaluation of increased alcohol-related consequences and cases admitted to the ED.

Clinical performance of cardiac Troponin I: A comparison between the POCT AQT90 FLEX and the Dimension Vista analyzer in an emergency setting.

BACKGROUND: Cardiac troponin [cTn (I or T)] is the preferred biomarker for the diagnosis of myocardial infarction (MI). AIM: We studied the analytical performance of the POCT AQT90 FLEX cTnI assay and its diagnostic accuracy, in comparison to the Dimension Vista cTnI method, in patients presenting to the Emergency Department (ED) with suspect of acute coronary syndrome (ACS). METHODS: 786 consecutive patients were enrolled. cTnI was measured at admission to the ED and about 3 and 6 hours later. The imprecision study was carried out using different lots of quality controls (QCs). ROC curve analysis was conducted using discharge diagnoses in order to verify the global diagnostic accuracy. RESULTS: The concentrations measured in the QCs ranging from 0.033 to 1.26µg/L show CVs% ranging from 2.81 to 7.56%, comparable to those declared by the manufacturer. Passing-Bablok and linear regression analysis show a high significant correlation (R2=0.90, p<0.0001); Bland-Altman test describes a statistically significant negative bias (Bias=-0.2336; 95%CI=-0.4217/-0.0456, p=0.0150). ROC curves obtained using Dimension Vista and AQT90 FLEX cTnI assays displayed similar clinical performance being not statistically significant the difference of the corresponding AUC. Comparing sensitivity and specificity of cTnI concentrations obtained from the ROC curve analysis using AQT90 FLEX, we found a "best cut-off" (0.014µg/L) lower than that declared from the manufacturer (0.023µg/L). CONCLUSIONS: The comparison of two different assays of cTnI against a diagnosis of acute MI (AMI) shows that both assays behave equally well with a high degree of sensitivity and specificity. The resulting "best cut-off" suggests that this AQT90 FLEX cTnI concentration could be evaluated as the potentially new "clinically usable" cut-off for AMI/myocardial necrosis diagnoses.

Pedestrian Inattention Blindness While Playing Pokémon Go as an Emerging Health-Risk Behavior: A Case Report.

BACKGROUND: Cases of trauma resulting from the use of mobile phones while driving motor vehicles have become quite common in recent years. Road injuries incurred by people playing video games on mobile phones (or other media devices) while walking have also become a cause for concern. Pokémon Go has been the world's most popular game since it was launched in July 2016, with more than 15 million players trying to catch all Pokémon available in the game; however, the case detailed here is the first reported accident in the medical literature caused by a pedestrian distracted by the game while crossing a street. OBJECTIVE: We aim to provide additional information on the innovative nature of distractions that generate risks in road-users, and to explore the underreporting of pedestrian-motor vehicle collisions due to mobile device usage. METHODS: We included in this case report a 25-year-old male who suddenly crossed a road while playing Pokémon Go and was hit by a van, reporting several injuries and being assisted by the Emergency Medical Service of our hospital (Padova, Italy). The patient's history, the circumstances in which the collision happened, imaging data, and clinical course information were recorded per our hospital's privacy policy. RESULTS: The patient hit by the van was playing Pokémon Go on his mobile phone while crossing a street, despite red traffic lights, which he did not notice due to of the distraction induced by the game. CONCLUSIONS: Mobile videogames that imply movement (ie, walking, running, cycling) to play are an effective way to improve physical activity practice, especially in adolescents and young adults. Nevertheless, cases like the one presented here point out that these games could pose a significant risk to users who play while walking, cycling, or driving in unsafe areas such as city streets, because players become distracted and may ignore surrounding hazards. Comprehensive, multilevel interventions are needed to reduce accidents caused by distraction, and to stress findings on the positive and negative effects of video games, which are becoming a source of public health concern. Health care providers should be aware of their chief role in these possible prevention strategies, based on their direct interactions with road incident victims.

Planking or the "Lying-Down Game:" Two Case Reports.

BACKGROUND: The monitoring and management of risks regarding children and young people admitted to the emergency department as a result of dangerous behaviors distributed via the Internet should be based on clinical reasoning and knowledge about these social media-related phenomena. Here we examine 2 cases of teenagers who reported severe injuries while performing the "planking" craze, a challenge that consists in lying face-down stiffly like a board on any kind of surface. OBJECTIVE: Our objective is to examine and describe the Internet craze called planking, also known as the "lying-down game," through 2 case reports from our experience, enriching this study with information gained through discussions with secondary school teenagers. METHODS: Details of the 2 case reports were taken from electronic medical records giving information on care support processes, care management, and the costs of traumatic episodes. Demographic data, hemoglobin and serum lactate values, and Injury Severity Scores were evaluated. The study took place in secondary schools of our city from 2013 to 2014 during medical education courses, with the aim of analyzing the influence of social media on teenagers' activities and behaviors. RESULTS: Both patients suffered multiple trauma injuries and needed high-level health assistance. The first patient underwent a splenectomy and the second one a nephrectomy; both of them required a long hospital stay (14 and 20 days, respectively), and the costs for their management have been estimated at US $27,000 and US $37,000, respectively. Their decision to perform the planking in dangerous locations was due to their ambition to gain peers' acclaim through shared videos and pictures. CONCLUSIONS: Reporting and understanding these cases may potentially help prevent future events occurring in similar circumstances: the scientific community cannot leave this problem unaddressed. There is also a role of education resources for health care professionals; for this, we must identify and follow up strange or misleading information found on websites. A key element of this research study was to report physicians' misperceptions concerning planking and, with these cases used for teaching purposes, improve knowledge of the clinical and forensic aspects of this emerging problem.

Complete blood count at the ED: preanalytic variables for hemoglobin and leukocytes.

OBJECTIVE: The objective of this study is to determine the ways in which preanalytic factors related to physiologic status can affect the complete blood cell count (CBC) in patients referring to an emergency department (ED). METHODS: Over a 1-year period, the results of hemoglobin (Hb) level and white blood cell (WBC) counts of the first CBC tests undertaken in consecutive patients (n = 11487) referring to the ED were compared with those obtained in the same patients at a second test undertaken within 24 hours of admission. A prospective evaluation of the same differences was made in another group (group 2) of 1025 consecutive ED patients, several clinical characteristics being taken into consideration. RESULTS: Mean Hb concentrations were higher in the first (range, 8.0-15.9 g/dL) than in the second test results (median overestimation, 0.4-0.8 g/dL; P < .0001). At multivariate analysis of results in group 2 patients, fluid administration (>0.5 L) and the presence of edema played a significant role in the initial overestimation of Hb level (P = .001 and P = .045, respectively). The comparison between leukocyte counts (WBC) showed that values from the first were higher than those in the second test (median overestimation ranging from 0.42 to 3.63 × 10(9)/L cells, in the range counts from 4.0 to 30.0 × 10(9)/L). None of the clinical factors studied appeared to have affected this overestimation. CONCLUSIONS: On interpreting CBC results in patients admitted to the ED, physicians must consider the effect of physiologic variables on Hb level (mainly hydration status) and WBC count (mental and physical stress).

Copeptin decrease from admission to discharge has favorable prognostic value for 90-day events in patients admitted with dyspnea.

BACKGROUND: With patients referred to emergency departments (EDs) for acute dyspnea, emergency physicians should consider all possible diagnoses and assess patients' risk stratification. Copeptin has been shown to have prognostic power for subsequent events, such as death and rehospitalization in patients admitted for dyspnea. The aim of this study was to investigate prognostic role of copeptin variations during hospitalization in patients admitted for dyspnea. METHODS: We conducted a prospective, multicentric, observational study in acute dyspneic patients in three ED centers in Italy. Clinical data and copeptin assessments were performed at admission, and at discharge. A 90-day follow-up was performed. RESULTS: A total of 336 patients were enrolled, and on the basis of final diagnosis distinguished into two groups: acute heart failure and no acute heart failure. Compared to a control group, in all studied population copeptin values at admission resulted in a significantly (p<0.001) higher median (maximum-minimum): 31 (0-905) versus 8 (0-13) pmol/L. Median copeptin value at admission was 42 (0-905) pmol/L in acute heart failure patients and 20 (0-887) pmol/L in no acute heart failure, respectively (p<0.001). In all studied patients and in each group copeptin at admission and discharge showed significant predictive value for 90-day events (p<0.001). Furthermore, in all patients population and in both groups Δ copeptin values from admission to discharge also showed significant predictive value for 90-day events (p<0.001). CONCLUSIONS: In patients admitted for acute dyspnea, admission, discharge and Δ copeptin variations have significant prognostic value from subsequent 90-day death and rehospitalization.

Differentiation of cardiac and noncardiac dyspnea using bioelectrical impedance vector analysis (BIVA).

BACKGROUND: There is no gold standard for the differential diagnosis of acute dyspnea despite the usefulness of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and lung ultrasound. No study has evaluated the contribution of bioelectrical impedance vector analysis (BIVA) in discriminating between cardiac and noncardiac dyspnea. We sought to determine whether a relationship exists between ultrasound detection of lung congestion, NT-proBNP, and BIVA in patients with acute dyspnea. METHODS AND RESULTS: Eligible patients were between 50 and 95 years, with an estimated glomerular filtration rate of ≥30 mL min(-1) 1.73 m(-2), who presented to an emergency department with dyspnea. Dyspnea was classified by reviewers blinded to BIVA as cardiac or noncardiac based on physical examination, electrocardiogram, chest X-ray, NT-proBNP, and B-lines of lung congestion on ultrasound. Overall, 315 patients were enrolled (median age 77 years, 48% male). An adjudicated diagnosis of cardiac dyspnea was established in 169 (54%). Using BIVA, vector positions below -1 SD of the Z-score of reactance were associated with peripheral congestion (χ(2) = 115; P < .001). BIVA measures were reasonably accurate in discriminating cardiac and noncardiac dyspnea (69% sensitivity, 79% specificity, 80% area under the receiver operating characteristic curve). CONCLUSIONS: In patients presenting with acute dyspnea, the combination of BIVA and lung ultrasound may provide a rapid noninvasive method to determine the cause of dyspnea.

Diagnostic pathways of the complex patients: rapid intensive observation in an Acute Medical Unit.

The present-day patients have complex diseases that are responsible for the great increase of medical interventions, overcrowding in emergency departments and access to the wards, increased waiting times and length of stay, difficult discharge, increased readmission rate and finally increased mortality. By breaking the steps of the patients pathways it allows us to simplify the problems and to face the individual aspects of the complexity related to the management of patients in the hospital. One solution that has been growing in popularity is the rapid intensive observation of the patients in acute hospital setting within Internal Medicine wards. This model has been otherwise defined with different terminology, but the most widely used name is Acute Medical Unit (AMU). We describe the model of an AMU within an Internal Medicine department as proposed and adopted in Anglo-Saxon countries, the methods of clinical approach and the practical organisation of the units in close collaboration with the ED ward. Finally we report our experience at an Internal Medicine department in Padova and the initial results obtained during the first 4 months of the project. Our approach of intensive rapid observation of intermediate risk patients admitted from the ED led to a significant reduction in the duration of hospitalization, without increasing readmission rate after discharge and fatality rate. Factors significantly associated to a short hospital stay were a preserved function and a lower number of previous admissions to the hospital. Several gray zones in the realisation and management of the project were identified and the possible solutions are still matter of discussion and debate.

Determinants of circulating asymmetric and symmetric dimethylarginines in patients evaluated for acute dyspnea.

BACKGROUND: The relationship between asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) plasma concentrations and acute heart failure is unknown. We evaluated ADMA and SDMA in patients with acute dyspnea. METHODS: We studied 57 dyspneic subjects (50-95 years), with estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1.73 m², presenting to the emergency department. Troponin I, N terminal-proBNP (NT-proBNP), ADMA, and SDMA were measured. Electrocardiogram, chest X-ray and lung ultrasound were performed. Patients were classified into cardiogenic dyspnea and non-cardiogenic dyspnea, and were also classified on the basis of renal function according to their eGFR. RESULTS: Two-way analysis of variance demonstrated that ADMA and SDMA did not differ for type of dyspnea, but increased in renal dysfunction. NT-proBNP significantly increased both in cardiogenic dyspnea and renal dysfunction. Multiple regression analysis demonstrated that after adjustment for troponin and dyspnea, the only variables which significantly correlated with SDMA plasma concentrations were renal function (ß = -0.47, p < 0.001) and NT-proBNP (ß = 0.28, p = 0.02). CONCLUSIONS: Neither type of dimethylarginine showed cardiogenic dyspnea to be a determinant for plasma concentrations. Renal dysfunction was a confounder for both ADMA and SDMA.
