To rate surgery's outcome, hand-specific instruments like the Michigan Hand Questionnaire (MHQ) are used as well as questionnaires which refers to the quality of life (QOL). In clinical daily grind, the SF-12 or the EQ-5D are common instruments to gain information about the patient's QOL. At the time, there is no current evidence available while using standardized questionnaires like the EQ-5D to capture the change in QOL in patients with CTS undergoing surgery. It would be interesting to assert that the investigation offers results about the patient's QOL and its change. Therefore, the aim of the study is to investigate the psychometric properties of the EQ-5D on patients with CTS undergoing surgery."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients from the Schulthess Klinik (Zurich, Switzerland) with will be asked to participate on the study.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* age over 18 years\n* diagnosed CTS\n* planned surgical decompression of the carpal tunnel\n* signed informed consent\n\nExclusion Criteria:\n\n* additional simultaneously performed hand surgery of the affected limb\n* recurrent surgery on the already involved hand\n* the other hand is already included in the study\n* disease, which do not allow appropriated analysis of data like central-neurological, psychiatric or metabolic disease\n* legal incompetence'}, 'identificationModule': {'nctId': 'NCT02276105', 'briefTitle': 'Investigation of Psychometric Properties of the EuroQoL EQ-5D-5L in Patients With Carpal Tunnel Syndrome', 'organization': {'class': 'OTHER', 'fullName': 'Schulthess Klinik'}, 'officialTitle': 'Investigation of Psychometric Properties of the EuroQoL EQ-5D-5L in Patients With Carpal Tunnel Syndrome', 'orgStudyIdInfo': {'id': 'Eq5d_val_cts'}}, 'armsInterventionsModule': {'interventions': [{'name': 'Questionnaires', 'type': 'OTHER', 'description': 'On three time-points (Baseline, Retest, Follow-Up), each participant has to fill out the questionnaires: Michigan Hand Questionnaire, EuroQol EQ-5D-5L and the Short Form SF-12 Health Survey'}]}, 'contactsLocationsModule': {'locations': [{'zip': '8008', 'city': 'Zurich', 'country': 'Switzerland', 'facility': 'Schulthess Klinik', 'geoPoint': {'lat': 47.36667, 'lon': 8.55}}], 'overallOfficials': [{'name': 'Herren Daniel, Dr. med.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Schulthess Klinik, Zurich, Switzerland'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Schulthess Klinik', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
