Considered that low-risk patients could benefit from a short hospital stay, aim of this study is to demonstrate that the use of PESI will lead physicians to discharge these patients earlier, thus reducing the duration of hospital stay of PE patients (primary outcome).\n\nOutpatients diagnosed with PE at the emergency department (ED) and admitted to participating units represent the target population\n\nAs the availability of DOACs may influence the duration of hospital stay, the secondary objectives of the present study are:\n\n1. to demonstrate that a shorter hospital stay for low-risk PE patients (independently on the method used to identify them) will reduce the incidence of hospital-associated complications and improve patients satisfaction and quality of life, without increasing the incidence of PE-related complications\n2. to demonstrate that the use of PESI, as opposed to clinical judgment alone, will be associated with a greater proportion of patients discharged early (\\< 72 hours from ED admission) or treated entirely at home (\\< 24 hours from ED admission).\n3. to demonstrate that the use of DOACs will reduce the duration of hospital stay of PE patients\n4. to demonstrate that the use of DOACs, as opposed to standard treatment, will be associated with a greater proportion of patients discharged early (\\< 72 hours from ED admission) or treated entirely at home (\\< 24 hours from ED admission).', 'detailedDescription': "STUDY DESIGN\n\nWithin 24 hours from acute PE diagnosis, each treating physician (local Investigator) will be centrally randomized. Treating physicians (local Investigator) of the participating Units will call the coordinating centres by phone for randomization. Before randomization, in order to avoid any influence on treatment choice, each treating physician (local Investigator) should declare in advance which treatment strategy will use for his patient (intention-to-treat), i.e. standard treatment with heparin plus vitamin K antagonist (standard group) or DOACs (DOACs group) Randomization will be stratified by treatment choice of the local Investigator. Each of two 'intention-to-treat' approaches will be therefore randomized to two arms, i.e. arm 1 or arm 2.\n\nArm 1: treating physicians must formally calculate PESI and report in the clinical record form\\* each day of hospitalization on top of routine clinical practice (standard care)\n\nArm 2: standard care (i.e. no formally calculation of PESI on top)\n\nRandomization will be performed centrally with a 1:1 ratio, following a computer-generated list of randomization.\n\nSTUDY POPULATION\n\n1.1 Population\n\nRandomised physicians:\n\nEach Local Investigator of participating canters. All participating centres are Internal Medicine Unit.\n\nPE population:\n\nConsecutive adult outpatients of any age, gender and race, with an objectively confirmed diagnosis of a suspected or unsuspected acute PE at the emergency department (ED) and admitted to participating units will be included.\n\nSuspected PE means that diagnosis has been made by an imaging test (computed tomographic pulmonary angiography \\[CTPA\\], pulmonary angiography, V/Q lung scan) prescribed by a treating physician who had clinical suspicion of PE.\n\nUnsuspected PE means that diagnosis has been made incidentally by an imaging test performed for other clinical indications (e.g. cancer staging or follow-up).\n\nObjective diagnosis of acute PE means: a positive computed tomographic pulmonary angiography (CTPA), a positive pulmonary angiography, a high-probability V/Q lung scan (or perfusion lung scan with negative chest X-ray), or intermediate probability V/Q or perfusion lung scan with proximal deep-vein thrombosis (DVT) documented by compression ultrasonography.\n\n1.2 Sample size calculation\n\nThe Investigators hypothesize that the distribution of hospital stay duration for PE will have a standard deviation of 4 days. The I vestigators also hypothesize that the mean duration of hospital stay will be reduced by at least 15% in PE patients whose treating physician will be randomised to formally use PESI and by 5% in PE patients whose treating physician will not be randomised to formally calculate PESI. Low-risk PE patients are almost 50% of all PE population. Therefore, with an α error of 0.05 and a statistical power (1-β error) of 80%, 200 patients for each group (a total of 400 patients) need to be enrolled to find a statistically significant difference (p\\<0.05) between the mean hospital stay length. As the variable 'hospital stay length' will have a non-normal distribution and needs to be expressed and reported as median, 10% extra patients need to be enrolled to reach a statistically significant difference with the previous statistical assumptions.\n\nFinal total sample size will be, therefore, of 440 patients (220 patients for each group)\n\nOUTCOMES\n\n1. Main study parameter/endpoint\n\n The primary outcome is the median length of hospital stay\n2. Secondary study parameters/endpoints\n\nThe secondary efficacy outcomes will be the following:\n\n1. health-system measures\n\n * proportion of patients undergoing short-hospital stay\n * proportion of patients undergoing complete home-treatment\n * post-discharge hospital re-admission\n * post-discharge outpatient visits to emergency department\n2. patient-related outcomes\n\n * quality of life (5-point Likert scale questionnaire)\n\nThe safety outcomes will be the following:\n\n1. overall mortality\n2. PE-related\n\n * PE-related mortality\n * recurrent PE and/or deep vein thrombosis (DVT)\n * major bleeding\n * clinically relevant non-major bleeding\n * minor bleeding\n * other anticoagulation-related complications (hematoma/infection at heparin or fondaparinux injection sites, heparin-induced thrombocytopenia)\n3. Hospitalization-related\n\n * hospital-acquired infections (pneumonia; urinary tract infection; other)\n * iatrogenic complications\n * immobilization syndrome\n * pressure sores\n\nOverall mortality, PE-related safety outcomes, post-discharge hospital re-admission and outpatient visits to emergency department will be measured at 14 days, 30 days, and 90 days."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Outpatients with objectively diagnosed PE, both suspected or unsuspected (e.g. during CT for cancer staging and/or follow-up)\n* Age \\> 18 years\n* Signature of written informed consent\n\nExclusion Criteria:\n\n* Children'}, 'identificationModule': {'nctId': 'NCT03002467', 'acronym': 'iAPP', 'briefTitle': 'Impact Analysis of Prognostic Stratification for Pulmonary Embolism', 'organization': {'class': 'OTHER', 'fullName': "Università degli Studi dell'Insubria"}, 'officialTitle': 'Impact Analysis of Prognostic Stratification for Pulmonary Embolism: A Randomized Controlled Trial', 'orgStudyIdInfo': {'id': 'iAPP study'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'PESI score', 'description': 'treating physicians must formally calculate PESI and report in the clinical record form\\* each day of hospitalization on top of routine clinical practice (standard care)', 'interventionNames': ['Other: PESI score']}, {'type': 'NO_INTERVENTION', 'label': 'Standard care', 'description': 'standard care (i.e. no formally calculation of PESI on top)'}], 'interventions': [{'name': 'PESI score', 'type': 'OTHER', 'armGroupLabels': ['PESI score']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Cuneo', 'country': 'Italy', 'geoPoint': {'lat': 44.39071, 'lon': 7.54828}}], 'overallOfficials': [{'name': 'Alessandro Squizzato, MD PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': "Università degli Studi dell'Insubria"}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': "Università degli Studi dell'Insubria", 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Associate Professor', 'investigatorFullName': 'Alessandro Squizzato', 'investigatorAffiliation': "Università degli Studi dell'Insubria"}}}}
