Determinants of antibiotic prescriptions in a large cohort of children discharged from a pediatric emergency department.

While there is evidence of high use of wide-spectrum antibiotics in children evaluated in the pediatric emergency departments, determinants of this behavior are still unclear. This study was aimed at defining the demographic, social, clinical, and laboratory factors that affect antibiotic prescriptions in children discharged from the emergency department. We performed a retrospective observational study of children aged younger than 18 years discharged from a pediatric university hospital between Jan. 1, 2015 and Dec. 31, 2020. We determined the proportion and type of antibiotic prescription according to demographic, social, clinical, laboratory, and imaging data, as well as doctor's expertise. Fifty-one thousand six hundred thirty-three children were included, and 13,167 (25.5%) received an antibiotic prescription. Amoxicilline/clavulanate (Am/Cl) was the most prescribed antibiotic (8453, 64.2% of all prescriptions). Factors independently associated with an antibiotic prescription were older age (OR = 1.62 [1.53-1.73] for age 2-5 years, OR = 1.77 [1.64-1.91] for age 6-10 years, OR = 1.36 [1.25-1.49] for age 11-18 years, p < 0.001 for all groups); being evaluated by a physician with > 3 years of pediatric expertise (OR = 1.22 [1.13-1.31], p < 0.001); fever peak higher than 40 °C (OR = 1.37 [1.21-1.54], p < 0.001); abnormal findings on auscultation (OR = 1.95 [1.75-2.17], p < 0.001), CRP values (OR = 1.63 [1.26-2.10] for CRP < 50 mg/L, and OR = 3.78 (2.75-5.21) for CRP ≥ 50 mg/L with respect to CRP not requested; p < 0.01); CXR results whatever positive (OR = 4.47 [3.62-5.52], p < 0.001) or negative (1.82 [1.62-2.04], p < 0.001); being diagnosed with upper respiratory tract infections (OR = 4.27 [4.04-4.51], p < 0.001), lower respiratory tract infections (OR = 5.35 [4.88-5.85]; p < 0.001), and UTI (OR = 9.33 [8.14-10.71], p < 0.001).    Conclusions: Overprescription of antibiotics, including Am/Cl, is relevant in pediatric emergency departments. Factors associated with overprescription are not limited to the clinical characteristics of the treated patients. These findings highlight the need for a new and comprehensive approach to ensure successful antibiotic stewardship initiatives in the emergency departments. What is Known: • Antibiotic resistance is a growing problem in medical practice, including in pediatrics. • Antibiotics are overprescribed in children assessed in the emergency department, but comprehensive and large studies are lacking. What is New: • Factors associated with overprescription are not limited to the clinical characteristics of the patients. • Non-clinical factors such as environmental variables, doctor's expertise, and attitudes to laboratory and radiological examinations affect prescription.

Are oral anticoagulants a risk factor for mild traumatic brain injury progression? A single-center experience focused on of direct oral anticoagulants and vitamin K antagonists.

BACKGROUND: Mild traumatic brain injury (TBI) in anticoagulated patients is a common challenge for emergency departments because of lack of appropriate epidemiological data and huge management variability for those under oral anticoagulation therapy. Given the discrepancies between guidelines, the aim of the present study was to quantify the association between oral anticoagulant therapy (either vitamin K antagonist (VKA) or direct oral anticoagulant (DOAC)) and the post-traumatic intracranial hemorrhage worsening compared to admission CT scan. METHODS: We included all consecutive records of patients admitted to our emergency department for mild TBI as chief complaint and with a positive admission CT scan. After statistical univariate comparison, cause-specific hazard ratio (HR) and 95% confidence interval (CI) were determined with the use of Cox proportional hazard model. RESULTS: In the study period, 4667 patients had a CT scan for mild TBI; 439 (9.4%) were found to have intracranial hemorrhage. Among these patients, 299 (68.1%) were prescribed observation and control CT: 46 (15.38%) were on anticoagulant therapy, 23 (50%) on VKA, and 23 (50%) on DOAC. In multivariate analysis, only oral anticoagulation therapy was significantly associated to an increased risk of intracranial hemorrhage progression (HR 2.58; 95% CI 1.411-4.703; p = .002 and HR 1.9; 95% CI 1.004-3.735; p = .0048 for VKA and DOAC, respectively). Surgery was due to isolated subdural hematoma in 87.5% of cases, to subdural hematoma associated with intraparenchymal hemorrhage in 9.38% and to intraparenchymal hemorrhage only in 3.12%; 13 cases (4.35%) deceased in intensive care unit. CONCLUSIONS: In our series, anticoagulation was associated to a significant increase in intracranial progression, leaving the question open as to what this implies in current clinical practice; subdural hematoma was the major finding associated to evolution and surgery. Against this background, further studies are needed to clarify patients' management and DOAC safety profile compared to VKA in mild TBI.

The Role of Early Procalcitonin Determination in the Emergency Departiment in Adults Hospitalized with Fever.

Background and Objectives: Fever is one of the most common presenting complaints in the Emergency Department (ED). The role of serum procalcitonin (PCT) determination in the ED evaluation of adults presenting with fever is still debated. The aim of this study was to evaluate if, in adults presenting to the ED with fever and then hospitalized, the early PCT determination could improve prognosis. Materials and Methods. This is a retrospective, mono-centric study, conducted over a 10-year period (2009-2018). We analyzed consecutive patients ≥18 years admitted to ED with fever and then hospitalized. According to quick sequential organ failure assessment (qSOFA) at admission, we compared patients that had a PCT determination vs. controls. Primary endpoint was overall in-hospital mortality; secondary endpoints were in-hospital length of stay, and mortality in patients with bloodstream infection and acute respiratory infections. Results. The sample included 12,062 patients, median age was 71 years and 55.1% were men. In patients with qSOFA ≥ 2 overall mortality was significantly lower if they had a PCT-guided management in ED, (20.5% vs. 26.5%; p = 0.046). In the qSOFA < 2 group the mortality was not significantly different in PCT patients, except for those with a final diagnosis of bloodstream infection. Conclusions. Among adults hospitalized with fever, the PCT evaluation at ED admission was not associated with better outcomes, with the possible exception of patients affected by bloodstream infections. However, in febrile patients presenting to the ED with qSOFA ≥ 2, the early PCT evaluation could improve the overall in-hospital survival.

SPONTANEOUS THYROID NODULE HEMORRHAGE IN THE EMERGENCY DEPARTMENT.

Objective: Spontaneous thyroid gland hemorrhage is a rare event. The present retrospective study considered its clinical impact and management in a referral center. Methods: Clinical records of adult patients accessed in the last 10 years (2009-2018) in the Emergency Department of Policlinico Gemelli IRCCS were reviewed to study patients with spontaneous thyroid nodule hemorrhage. All demographic and radiologic or surgical parameters were included, with special attention to the characteristics of thyroid disease and clinical management. Results: Among the 631,129 adults who were registered during the period considered, 59 consecutive patients were included in the study. The mean age was 48.3 ± 14.3 years, with a prevalence of females. The main symptoms were acute neck pain, dyspnea, and dysphagia. All patients underwent ultrasound evaluation; computed tomography scan was performed on only 3 patients, finding one case of active intranodular bleeding requiring urgent surgery. Six patients required hospitalization; the others were discharged and referred for ambulatory endocrinology follow-up. Among them, 7 patients underwent surgery in the next 6 months, with malignant disease found in 3 cases (5.1%). Conclusion: Intrathyroidal spontaneous hemorrhage is a rare event, occurring in multinodular as well as in single-nodule thyroid disease. Although the clinical course is mostly benign, this condition should be carefully evaluated as, in rare circumstances, active bleeding could induce airway obstruction with the need for emergency surgery. Patients should be referred to endocrinology ambulatory follow-up because bleeding could arise as the first sign of malignant lesions in some cases.

Acute pancreatitis in elderly patients: a single-center retrospective evaluation of clinical outcomes.

Introduction: Acute pancreatitis (AP) incidence in the elderly population has increased in the last years. However, the role of age as influencing factor on the AP clinical course is still debated. Methods: We reviewed clinical records of consecutive patients admitted with diagnosis of AP. Patients were divided in elderly (≥65 years) and non-elderly (<65 years). Primary endpoint was comparison of overall mortality. Secondary endpoint included ICU admission, in-hospital length of stay (LOS) and surgical procedures. Results: We enrolled 352 elderly and 532 non-elderly patients. A higher mortality rate (7.4% vs 1.9%; p < .001), ICU admission rate (18.9% vs 6.3%; p < .001) and prolonged length of hospital stay (9 (6-14) vs 7 (5-11.7) days; p = .01) were registered in the ≥65 years group. Multivariate analysis identified age (OR: 3.5; 95% CI:1.645-7.555; p = .001), a higher Ranson score at admission (OR: 5.52; 95% CI:1.11-27.41; p<.001) and necrotic pancreatitis (OR: 8.6; 95% CI:2.46-30.27; p = .001) as independent predictors of mortality. Conversely age and necrotic pancreatitis were independent risk factors for higher LOS and ICU admission. Conclusions: Patients with AP and age ≥65 years have a higher mortality, ICU admission and prolonged LOS. Early recognition and prompt treatment are key elements to improve outcomes in this population.

A new clinical score for cranial CT in ED non-trauma patients: Definition and first validation.

INTRODUCTION: Well recognized guidelines are available for the use of cranial computed tomography (CCT) in traumatic patients, while no definitely accepted standards exists to for CCT in patients without history of head injury. The aim of this study is to propose an easy clinical score to stratify the need of CCT in emergency department (ED) patients with suspect non-traumatic intracranial pathology. METHODS: We retrospectively evaluated patients presenting to the ED for neurological deficit, postural instability, acute headache, altered mental status, seizures, confusion, dizziness, vertigo, syncope, and pre-syncope. We build a score for positive CCT prediction by using a logistic regression model on clinical factors significant at univariate analysis. The score was validated on a population of prospectively observed patients. RESULTS: We reviewed clinical data of 1156 patients; positivity of CCT was 15.2%. Persistent neurological deficit, new onset acute headache, seizures and/or altered state of consciousness, and transient neurological disorders were independent predictors of positive CCT. We observed 508 patients in a validation prospective cohort; CCT was positive in 11.3%. Our score performed well in validation population with a ROC AUC of 0.787 (CI 95% 0.748-0.822). Avoiding CT in score 0 patients would have saved 82 (16.2%) exams. No patients with score 0 had a positive CCT findings; score sensitivity was 100.0 (CI 95% 93.7-100.0). CONCLUSIONS: A score for risk stratification of patients with suspect of intra-cranial pathology could reduce CT request in ED, avoiding a significant number of CCT while minimizing the risk of missing positive results.

Clinical Evolution of Acute Vestibular Syndrome: Longitudinal Retrospective Analysis of Epidemiological Data and Prognostic Factors for Recovery.

We evaluated the clinical features of patients admitted to the ED with acute vertigo, verifying symptoms after one month and one year to establish epidemiological factors and predictors of resolution. We reviewed 233 records of patients admitted to ED for acute vertigo (125 F and 85 M, mean age 56.12 years). We analyzed the correlation between time of resolution (at one month and one year) and symptoms duration (subjective and/or objective vertigo, instability, cervical pain, audiological, neurological, and neurovegetative symptoms), comorbidities, and therapies, the result of the clinical and instrumental vestibular examination. Resolution of acute vertigo occurred in 81.1%, while persistence of vertigo one year after ED access was reported in 18.8%. There were 135 patients who recovered in one month. The presence of instability, auditory and neurovegetative symptoms, and neck pain represents a significant factor for recovery within one year. Age over 65 and a history of hypertension are associated with a worst recovery. Patients with spontaneous Nystagmus or positive HIT showed a significant difference in symptoms recovery within one month and one year. Presence of positional Nystagmus represents a positive prognostic factor. Our findings emphasize the importance of clinical evaluation of the acute vertigo, helping the clinicians to define central or peripheral diagnosis and predict the resolution of vertigo.

Procalcitonin for the early discrimination of fever etiology in patients with systemic autoimmune diseases attending the emergency department.

In febrile patients with known systemic autoimmune disease, early discrimination between infection and disease flare often represents a clinical challenge. This study aimed at evaluating the efficacy of procalcitonin (PCT) and other common inflammatory biomarkers in discriminating disease flare from bacterial infections in the Emergency Department (ED). In a cross-sectional observational retrospective study, we identified consecutive febrile patients with a known diagnosis of systemic autoimmune disease, admitted to the ED, and subsequently hospitalized. Flare vs infective disease was defined on clinical records at hospital discharge. Dosage of common inflammatory markers was performed at ED admission. Out of 177 patients, those with infection were most commonly elderly, frail, and with reduced peripheral oxygen saturation at admission. When compared to C-reactive protein (CRP) and white blood count (WBC), PCT showed the best performance in discriminating infections vs flare. However, only at a very high threshold value of 2 ng/ml, the PCT had a satisfactory negative predictive value of 88.9%, although with a very low specificity of 13.6% and a positive predictive value of 35.8%. Our data suggest that in the ED setting, the early PCT determination has low accuracy in the differentiation of disease flare from infection in patients with known rheumatologic disease. However, the PCT could be useful in elderly and comorbid subjects, in supporting clinical assessment and in recognizing those febrile patients needing prompt antibiotic treatment.

A New Clinical Prediction Rule for Infective Endocarditis in Emergency Department Patients With Fever: Definition and First Validation of the CREED Score.

Background Infective endocarditis (IE) could be suspected in any febrile patients admitted to the emergency department (ED). This study was aimed at assessing clinical criteria predictive of IE and identifying and prospectively validating a sensible and easy-to-use clinical prediction score for the diagnosis of IE in the ED. Methods and Results We conducted a retrospective observational study, enrolling consecutive patients with fever admitted to the ED between January 2015 and December 2019 and subsequently hospitalized. Several clinical and anamnestic standardized variables were collected and evaluated for the association with IE diagnosis. We derived a multivariate prediction model by logistic regression analysis. The identified predictors were assigned a score point value to obtain the Clinical Rule for Infective Endocarditis in the Emergency Department (CREED) score. To validate the CREED score we conducted a prospective observational study between January 2020 and December 2021, enrolling consecutive febrile patients hospitalized after the ED visit, and evaluating the association between the CREED score values and the IE diagnosis. A total of 15 689 patients (median age, 71 [56-81] years; 54.1% men) were enrolled in the retrospective cohort, and IE was diagnosed in 267 (1.7%). The CREED score included 12 variables: male sex, anemia, dialysis, pacemaker, recent hospitalization, recent stroke, chest pain, specific infective diagnosis, valvular heart disease, valvular prosthesis, previous endocarditis, and clinical signs of suspect endocarditis. The CREED score identified 4 risk groups for IE diagnosis, with an area under the receiver operating characteristic curve of 0.874 (0.849-0.899). The prospective cohort included 13 163 patients, with 130 (1.0%) IE diagnoses. The CREED score had an area under the receiver operating characteristic curve of 0.881 (0.848-0.913) in the validation cohort, not significantly different from the one calculated in the retrospective cohort (P=0.578). Conclusions In this study, we propose and prospectively validate the CREED score, a clinical prediction rule for the diagnosis of IE in patients with fever admitted to the ED. Our data reflect the difficulty of creating a meaningful tool able to identify patients with IE among this general and heterogeneous population because of the complexity of the disease and its low prevalence in the ED setting.

Guillain-Barré syndrome from an emergency department view: how to better predict the outcome?

OBJECTIVE: In Guillain-Barre syndrome (GBS), respiratory failure is the most serious manifestation and mechanical ventilation (MV) is required in approximately 20% of the patients. In this retrospective study, we aimed to evaluate clinical factors that can be evaluated in the Emergency Department which may influence the short-term prognosis of GBS patients. METHODS: Data were acquired regarding age, sex, antecedent infections, neurological signs and symptoms, cerebrospinal fluid examination, nerve conduction studies, treatment of GBS, need for MV, length of stay in the hospital, and discharge destination (home or rehabilitation). Charlson Comorbidity Index and modified Erasmus GBS outcome score (mEGOS) were collected on admission. RESULTS: Seventy-eight GBS patients were recruited with a mean age of 53.9 (range 19-81). Sixty-nine (88.46%) were diagnosed with GBS and nine (11.54%) had classic Miller-Fisher syndrome. Mean values for the Charlson Comorbidity index were 1.20 ± 1.81, and the values of mEGOS were 2.4 ± 1.6. The rate of home discharge and rehabilitation was similar between elderly and younger patients. Patients who required MV had higher mEGOS (p-value=0.061). Regarding the electrophysiological subtypes, we did not observe a significant difference between AIDP and AMAN/AMSAN concerning the need for MV, the type of discharge, values of mEGOS and Charlson Comorbidity Index. DISCUSSION: A significant correlation was found between mEGOS and the need for MV. Age did not influence the short-term prognosis of GBS patients. mEGOS may be a useful tool for predicting outcomes in patients with GBS and higher mEGOS scores on admission significantly correlated with poor outcomes.

Use of POCUS in Chest Pain and Dyspnea in Emergency Department: What Role Could It Have?

Chest pain and dyspnea are common symptoms in patients presenting to the emergency room (ER); oftentimes it is not possible to clearly identify the underlying cause, which may cause the patient to have to return to the ER. In other cases, while it is possible to identify the underlying cause, it is necessary to perform a large number of tests before being able to make a diagnosis. Over the last twenty years, emergency medicine physicians have had the possibility of using ultrasound to help them make and rule out diagnoses. Specific ultrasound tests have been designed to evaluate patients presenting with specific symptoms to ensure a fast, yet complete, evaluation. In this paper, we examine the role of ultrasound in helping physicians understand the etiology behind chest pain and dyspnea. We analyze the different diseases and disorders which may cause chest pain and dyspnea as symptoms and discuss the corresponding ultrasound findings.

Frailty Assessment in the Emergency Department for Patients ≥80 Years Undergoing Urgent Major Surgical Procedures.

OBJECTIVES: To evaluate, in a cohort of adults ≥80 years old, the frailty status at the emergency department (ED) admission, for the in-hospital death risk stratification of patients needing major surgical procedures. DESIGN: Single-center prospective observational cohort study. SETTING AND PARTICIPANTS: The study was conducted in the ED of a teaching hospital. We enrolled all patients ≥80 years old consecutively admitted to the ED for conditions requiring urgent surgical procedures, between 2018 and 2021. METHODS: Clinical variables and frailty status assessed in the ED were evaluated for the association with all-cause in-hospital death. The parameters evaluated were frailty [assessed by the Clinical Frailty Scale (CFS)], comorbidities, physiological parameters, type of surgery needed, laboratory values at admission. Cox regression analysis was used to identify independent risk factors for poor outcomes. RESULTS: The study enrolled 1039 patients aged ≥80 years [median age 85 years (interquartile range 82-89); 445 males (42.8%)]. Overall, 127 patients (12.2%) were classified as nonfrail (CFS score 1-3), 722 (69.5%) as mild frail (CFS score 4-6), and 190 (18.3%) as frail (CFS score 7-9). The covariate-adjusted analysis revealed that severe frailty [hazard ratio (HR) 12.55, 95% CI 2.96-53.21, P = .016], ≥3 comorbidities (HR 2.08, 95% CI 1.31-3.31, P = .002), shock at ED presentation (HR 3.58, 95% CI 2.16-5.92, P < .001), anemia (HR 1.88, 95% CI 1.17-3.04, P = .009), and neurosurgery procedures (HR 3.97, 95% CI 1.98-7.96, P < .001) were independent risk factors for in-hospital death. CONCLUSIONS AND IMPLICATIONS: In patients aged ≥80 years undergoing urgent surgical procedures, the evaluation of functional status in the ED could predict the risk of in-hospital death. Frail patients have an increased risk of death and major complications, whereas those with mild frailty have a similar prognosis compared with the more fit ones. Nonsurgical management should be considered in the case of severely frail and comorbid patients aged ≥80 years needing neurosurgery or abdominal surgery.

Long-Term Effects of Hospitalization for COVID-19 on Frailty and Quality of Life in Older Adults ≥80 Years.

Objectives: This study aimed to assess the effects of frailty and the perceived quality of life (QOL) on the long-term survival (at least 1 year) of patients ≥ 80 years hospitalized for COVID-19 and the predictors of frailty and QOL deterioration in survivors. Design: This is a single-center, prospective observational cohort study. Setting and Participants: The study was conducted in a teaching hospital and enrolled all COVID-19 patients ≥80 years old consecutively hospitalized between April 2020 and March 2021. Methods: Clinical variables assessed in the Emergency Department (ED), and during hospitalization, were evaluated for association with all-cause death at a follow-up. Frailty was assessed by the clinical frailty scale (CFS), and the QOL was assessed by the five-level EuroQol EQ-5d tool. Multivariate Cox regression analyses and logistic regression analyses were used to identify independent factors for poor outcomes. Results: A total of 368 patients aged ≥80 years survived the index hospitalization (age 85 years [interquartile range 82-89]; males 163 (44.3%)). Compared to non-frail patients (CFS 1-3), patients with CFS 4-6 and patients with CFS 7-9 had an increased risk of death (hazard ratio 6.75 [1.51, 30.2] and HR 3.55 [2.20, 5.78], respectively). In patients alive at the 1-year follow-up, the baseline QOL was an independent predictor of an increase in frailty (OR 1.12 [1.01, 1.24]). Male sex was associated with lower odds of QOL worsening (OR 0.61 [0.35, 1.07]). Conclusions and Implications: In older adults ≥80 years hospitalized for COVID-19, the frailty assessment by the CFS could effectively stratify the risk of long-term death after discharge. In survivors, the hospitalization could produce a long-term worsening in frailty, particularly in patients with a pre-existing reduced baseline QOL. A long-term reduction in the perceived QOL is frequent in ≥80 survivors, and the effect appears more pronounced in female patients.

Early Prognostic Stratification of Clostridioides difficile Infection in the Emergency Department: The Role of Age and Comorbidities.

Clostridioides difficile infection (CDI) represents a significant cause of morbidity and mortality, mainly in older and frail subjects. Early identification of outcome predictors, starting from emergency department (ED) admission, could help to improve their management. In a retrospective single-center study on patients accessing the ED for diarrhea and hospitalized with a diagnosis of CDI infection, the patients' clinical history, presenting symptoms, vital signs, and laboratory exams at ED admission were recorded. Quick sequential organ failure assessments (qSOFA) were conducted and Charlson's comorbidity indices (CCI) were calculated. The primary outcomes were represented by all-cause in-hospital death and the occurrence of major cumulative complications. Univariate and multivariate Cox regression analyses were performed to establish predictive risk factors for poor outcomes. Out of 450 patients, aged > 81 years, dyspnea at ED admission, creatinine > 2.5 mg/dL, white blood cell count > 13.31 × 109/L, and albumin < 30 µmol/L were independently associated with in-hospital death and major complications (except for low albumin). Both in-hospital death and major complications were not associated with multimorbidity. In patients with CDI, the risk of in-hospital death and major complications could be effectively predicted upon ED admission. Patients in their 8th decade have an increased risk independent of comorbidities.

Gastric emergencies in older adults: not always the same old story! A tertiary care emergency department observational cohort study.

OBJECTIVE: To analyse and compare the clinical outcomes between patients ≥80 years and 65-79 years, who presented to our emergency department (ED) with the two most common gastric emergency (GE) clinical presentation, that is, gastric bleeding and gastric perforation. DESIGN: Single-centre retrospective cohort study. PARTICIPANTS: A total of 1011 patients were enrolled: 421 patients aged ≥80 years were compared with a group of 590 patients aged 65-79 years. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was to compare the overall mortality. Secondary outcomes included major complications, in-hospital length of stay (LOS) and need for surgical procedures. RESULTS: Patients ≥80 years with GE had different presentations at ED compared with younger patients: they had higher gastrointestinal bleeding (24.9% vs 16.3%, p=0.001), anemisation (14.5% vs 8.8%, p=0.005) and shock (10.9% vs 5.1%, p=0.001) rates. Median LOS, cumulative major complications and mortality rates were similar among the two groups.Multivariate analysis identified shock, gastric malignancy and gastric fistula as independent predictors for survival. CONCLUSIONS: Patients ≥80 years with GE did not have a higher mortality rate and cumulative major complications as compared to younger elderly patients. Invasive treatments were not associated with a different prognosis in this age group.

Management of acute cholecystitis in elderly patients: A propensity score-matched analysis of surgical vs. medical treatment.

BACKGROUND: Acute cholecystitis (AC) is a life-threatening emergency in elderly patients. AIMS: To compare the commonly used management strategies for elderly patients with AC as well as resulting morbidity, mortality and length of hospital stay (LOS). METHODS: All patients ≥ 65 years admitted to our emergency department for AC between January 1st, 2014 and December 31st, 2018 were included in the study. We compared patients that received medical treatment to patients who received operative procedures. In order to correct for baseline covariates and factors associated to clinical management, we used a 1:1 propensity score matching (PSM) analysis. The primary outcome was the overall in-hospital mortality. Secondary outcomes included occurrence of major complications and LOS. RESULTS: A total of 1075 patients were enrolled: 483 patients received a medical treatment and 592 patients underwent interventional procedures. After PSM, 770 patients (385 for each treatment group) were included in the analysis. The analysis revealed that both mortality and cumulative major complications were similar in medical and interventional group. We found that among comorbidities, Charlson comorbidity index and congestive heart failure were significantly higher in the medical treatment group (5 [4-6] vs. 4 [3-6] and 11.7% vs. 4.7%, respectively; p<0.001). LOS was slightly lower in the medical treatment group (7.0 days [4.9-11.1] vs. 7.9 [4.9-13.5]; p = 0.046). CONCLUSION: Medical management outcomes for AC in elderly patients were similar to operative treatments in terms of mortality and cumulative major complications. A conservative approach should always be considered.

Prognostic Role of Serum Procalcitonin Measurement in Adult Patients Admitted to the Emergency Department with Fever.

Background and Objectives. Fever is one of the most common presenting complaints in the Emergency Department (ED). This study aimed at evaluating the prognostic role of serum Procalcitonin (PCT) measurement among adult patients admitted to the ED with fever. Materials and Methods. This is a retrospective cross-sectional study including all consecutive patients admitted to ED with fever and subsequently hospitalized in a period of six-year (January 2014 to December 2019). Inclusion criteria were age > 18 years, fever (T ≥ 38 °C) or chills within 24 h from presentation to the ED as the main symptom, and availability of a PCT determination obtained <24 h since ED access. The primary endpoint was overall in-hospital mortality. Results. Overall, 6595 patients were included in the study cohort (3734 males, 55.6%), with a median age of 71 [58-81] years. Among these, based on clinical findings and quick sequential organ failure assessment (qSOFA), 422 were considered septic (36.2% deceased), and 6173 patients non-septic (16.2% deceased). After correction for baseline covariates, a PCT > 0.5 ng/mL was an independent risk factor for all-cause in-hospital death in both groups (HR 1.77 [1.27-2.48], and 1.80 [1.59-2.59], respectively). Conclusions. Among adult patients admitted with fever, the PCT assessment in ED could have reduced prognostic power for patients with a high suspicion of sepsis. On the other hand, it could be useful for sepsis rule-out for patients at low risk. In these latter patients, the prognostic role of PCT is higher for those with a final diagnosis of bloodstream infection.

Early Procalcitonin Assessment in the Emergency Department in Patients with Intra-Abdominal Infection: An Excess or a Need?

Background: Intra-abdominal infection (IAI) is a wide range of intra-abdominal disease. Management involves empirical therapy and source control. Procalcitonin (PCT) has been suggested to assist in defining individual infection status and delivering individualized therapy. The aim of this study was to investigate the effects on patient outcomes of an early procalcitonin (PCT) assessment (in the emergency department [ED]) in patients with IAI. Methods: This was a retrospective, mono-centric study evaluating consecutive patients admitted to the ED from 2015 to 2019 with diagnosis of IAI. According to whether there had been PCT determination in the ED, patients were divided into no ePCT determination (no-ePCT) and early PCT determination in the ED (ePCT). The primary endpoint was the intra-hospital mortality rate. Secondary endpoints were occurrence of major complications and length of hospital stay (LOS). The propensity score match (PSM) was generated using a logistic regression model on the baseline covariates considered to be potentially influencing the decision to determine PCT in the ED and confounding factors identified as significant at a preliminary statistical analysis with respect to in-hospital death. Results: A series of 3,429 patients were included. The ePCT group consisted to 768 (22.4%), whereas the no-ePCT group contained 2,661 patients (77.6%). When the PSM was matched to the two groups, no significant difference was observed. Considering patients with uncomplicated infections, the PCT determination was associated with a higher mortality rate. We found no significant differences regarding outcomes with the exception of LOS, which was slightly longer in the ePCT group. However, we observed a tendency toward a minor difference in the number of complications in the ePCT group, in particular a reduced rate of progression to sepsis. Conclusion: Early PCT determination could be irrelevant in IAIs. The PCT value may be cost-effective and possibly improve the prognosis in cIAIs. Further research is needed to understand the optimal use of PCT, including in combination with other emerging diagnostic tests.

Frailty Assessment in the Emergency Department for Risk Stratification of COVID-19 Patients Aged ≥80 Years.

OBJECTIVES: To evaluate, in a cohort of adults aged ≥80 years, the overlapping effect of clinical severity, comorbidities, cognitive impairment, and frailty, for the in-hospital death risk stratification of COVID-19 older patients since emergency department (ED) admission. DESIGN: Single-center prospective observational cohort study. SETTING AND PARTICIPANTS: The study was conducted in the ED of a teaching hospital that is a referral center for COVID-19 in central Italy. We enrolled all patients with aged ≥80 years old consecutively admitted to the ED between April 2020 and March 2021. METHODS: Clinical variables assessed in the ED were evaluated for the association with all-cause in-hospital death. Evaluated parameters were severity of disease, frailty, comorbidities, cognitive impairment, delirium, and dependency in daily life activities. Cox regression analysis was used to identify independent risk factors for poor outcomes. RESULTS: A total of 729 patients aged ≥80 years were enrolled [median age 85 years (interquartile range 82-89); 346 were males (47.3%)]. According to the Clinical Frailty Scale, 61 (8.4%) were classified as fit, 417 (57.2%) as vulnerable, and 251 (34.4%) as frail. Severe disease [hazard ratio (HR) 1.87, 95% confidence interval (CI) 1.31-2.59], ≥3 comorbidities (HR 1.54, 95% CI 1.11-2.13), male sex (HR 1.46, 95% CI 1.14-1.87), and frailty (HR 6.93, 95% CI 1.69-28.27) for vulnerable and an overall HR of 12.55 (95% CI 2.96-53.21) for frail were independent risk factors for in-hospital death. CONCLUSIONS AND IMPLICATIONS: The ED approach to older patients with COVID-19 should take into account the functional and clinical characteristics of patients being admitted. A sole evaluation based on the clinical severity and the presence of comorbidities does not reflect the complexity of this population. A comprehensive evaluation based on clinical severity, multimorbidity, and frailty could effectively predict the clinical risk of in-hospital death for patients with COVID-19 aged ≥80 years at the time of ED presentation.
