Therefore, the investigators are doing a study to see if an internet-based decision aid can improve the quality of decision making for substitute decision makers of patients who are in the intensive care unit (ICU).', 'detailedDescription': "The process of making a decision about whether or not to provide prolonged life support is seriously deficient among clinicians and the surrogate decision makers for critically ill patients. To address this problem, we propose a randomized, controlled trial to determine if an innovative web-based decision aid compared to usual care control can improve the quality of decision making (defined as clinician-surrogate concordance for prognosis, quality of communication, and medical comprehension), reduce surrogates' psychological distress (depression, anxiety, and post-traumatic stress syndrome disorder (PTSD) symptoms), and reduce patients' health care costs over 6-month follow up. We will enroll 410 surrogate decision makers for 273 patients (expected average of 1.5 surrogates per patient). This study has the potential both to improve how clinicians and surrogates interact in intensive care units and to increase the likelihood that life support decisions are aligned with patients' values."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria (Patient characteristics required for surrogate inclusion)\n\n* age ≥18\n* ≥10 days of mechanical ventilation interrupted by \\<96 continuous hours of unassisted breathing (including invasive and non-invasive ventilation)\n* no anticipation of imminent (24 hours) death or extubation by the attending.\n\nExclusion Criteria (Patient characteristics that will exclude surrogates from study enrollment):\n\n* possession of decisional capacity\n* no identifiable surrogate, surrogate is unavailable for study procedures such as interviews\n* imminent organ transplantation\n* chronic neuromuscular disease\n* physician refuses permission to approach family and/or patient for consent\n* admission for severe burns\n* admission for high cervical spine injury\n* ventilation for \\>21 days.\n\nInclusion criteria for surrogate decision makers:\n\n* age ≥18\n* self-identified as participating directly in health care decision making for the incapable patient under relevant state law\n\nExclusion criteria for surrogate decision makers:\n\n* do not personally know the patient\n* need translation assistance because of poor English fluency (the decision aid has not been validated in other languages)\n* history of clinically important neurological disorder (e.g., dementia)\n* patient dies after meeting inclusion criteria but before surrogates provide consent\n\nPhysician and nurse inclusion criteria:\n\n* ICU attending or fellow (physicians) at the time of surrogate enrollment\n* bedside ICU nurse present at the time of surrogate enrollment'}, 'identificationModule': {'nctId': 'NCT01751061', 'briefTitle': 'Improving Decision Making for Patients With Prolonged Mechanical Ventilation', 'organization': {'class': 'OTHER', 'fullName': 'Duke University'}, 'officialTitle': 'Improving Decision Making for Patients With Prolonged Mechanical Ventilation', 'orgStudyIdInfo': {'id': 'Pro00021965'}, 'secondaryIdInfos': [{'id': 'R01HL109823-01A1', 'link': 'https://reporter.nih.gov/quickSearch/R01HL109823-01A1', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Decision aid', 'description': 'Web-based decision aid (decision support tool) provided to surrogate decision maker', 'interventionNames': ['Behavioral: Decision aid']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Usual care', 'description': 'usual care in an intensive care unit setting', 'interventionNames': ['Other: Usual care']}], 'interventions': [{'name': 'Decision aid', 'type': 'BEHAVIORAL', 'description': 'A web-based decision aid to assist surrogate decision makers in prolonged mechanical ventilation decisions', 'armGroupLabels': ['Decision aid']}, {'name': 'Usual care', 'type': 'OTHER', 'description': 'usual ICU care', 'armGroupLabels': ['Usual care']}]}, 'contactsLocationsModule': {'locations': [{'zip': '27599', 'city': 'Chapel Hill', 'state': 'North Carolina', 'country': 'United States', 'facility': 'University of North Carolina', 'geoPoint': {'lat': 35.9132, 'lon': -79.05584}}, {'zip': '27710', 'city': 'Durham', 'state': 'North Carolina', 'country': 'United States', 'facility': 'Duke University', 'geoPoint': {'lat': 35.99403, 'lon': -78.89862}}, {'zip': '15261', 'city': 'Pittsburgh', 'state': 'Pennsylvania', 'country': 'United States', 'facility': 'University of Pittsburgh', 'geoPoint': {'lat': 40.44062, 'lon': -79.99589}}, {'zip': '98195', 'city': 'Seattle', 'state': 'Washington', 'country': 'United States', 'facility': 'University of Washington', 'geoPoint': {'lat': 47.60621, 'lon': -122.33207}}], 'overallOfficials': [{'name': 'Christopher E Cox, MD MPH', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Duke University'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Duke University', 'class': 'OTHER'}, 'collaborators': [{'name': 'University of North Carolina, Chapel Hill', 'class': 'OTHER'}, {'name': 'University of Pittsburgh', 'class': 'OTHER'}, {'name': 'University of Washington', 'class': 'OTHER'}, {'name': 'National Heart, Lung, and Blood Institute (NHLBI)', 'class': 'NIH'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
