Prevalence of risk factors for CHD in HIV-infected individuals receiving ART in the Swiss HIV Cohort Study (SHCS) is high. This cluster randomised controlled trial is nested into the SHCS and will investigate whether physicians randomised to the routine provision of risk profiles from their patients receiving ART will improve the management of risk factors in HIV-infected patients compared to control physicians not routinely receiving such information. Risk profiles will be generated by the SHCS data center and provided to clinicians in all study centers.', 'detailedDescription': "Evidence from the D.A.D. study, an international cohort study which includes a large proportion of SHCS patients, suggests that exposure to antiretroviral therapy (ART) increases the risk of coronary heart disease (CHD) most likely due to ART induced metabolic changes like dyslipidemia, insulin resistance, and type II diabetes. The exact mechanisms for these metabolic changes and whether specific classes or combinations of ART are causally related to these changes are not known. Of males aged \\< 40 and \\> 40 years in the SHCS, 8.8% and 32.5% are at moderate (10% - 20%) and 1.7% and 6.9% at high (≥ 20%) risk of CHD in 10 years according to the Framingham algorithm. The overall percentage at moderate and high 10-year risk of CHD was 14.9% and 3.0%, respectively. Therefore, an intervention to reduce CHD risk among individuals at high risk for CHD is warranted. We propose a randomised controlled cluster intervention trial to reduce total cholesterol in all HIV-infected individuals in the SHCS (primary endpoint) and in those with greater than or equal to 10% 10 year risk of CHD based on the Framingham score (secondary endpoint). The intervention is the receipt of structured continuously updated information on CHD risk factors and treatment of CHD risk factors of HIV-infected patients. Randomisation will be done at the physician level and stratified by centre (7 centres of the SHCS, outpatient clinic or hospital), and size of patient volume for registered private practices. For physicians randomised to the intervention group, a flow sheet with information on risk factors and treatment status of CHD will be provided for each of their patients every 6 months by the SHCS data centre. Each centre and each physician treating SHCS patients will receive internationally and locally approved guidelines for the management of risk factors for CHD in HIV-infected patients. The intervention will be limited to 18 months. Our goal is a 7% reduction in total cholesterol (primary endpoint) between the intervention and the control group in the entire cohort. With alfa-error of 5%, power of 80% and a loss to follow-up of 10%, 408 patients per arm will be needed. Sample size calculations adapted to the cluster design of the trial show that we have sufficient power to detect a 12% reduction in total cholesterol in patients receiving ART and at moderate to high risk of CHD. Further secondary endpoints are a reduction of systolic and diastolic blood pressure and of overall Framingham risk score. We will additionally monitor whether changes in ART due to high risk of CHD, or treatment of CHD risk factors decreases the proportion of patients with non-sustained control of HIV-viremia. Data from this nested cluster trial will provide important information as to whether provision of an individual's CHD profile will improve monitoring and reduce CHD risk factors in HIV-infected patients in the SHCS."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nFor analysis of the primary endpoint:\n\n* All individuals in the SHCS\n\n * aged 18 or older\n * have a cohort visit in the 12 months preceding the randomisation date with a complete baseline dataset on CHD risk factors\n\nFor analysis of secondary endpoints:\n\n* All individuals in the SHCS\n\n * aged 18 or older\n * have a cohort visit in the 12 months preceding the randomisation date with a complete baseline dataset on CHD risk factors\n * at least 3 months of ART and at moderate to high risk of CHD (10% 10 years risk of CHD according to the Framingham risk score).\n\nExclusion Criteria:\n\n* Pregnant females\n* Patients in the SHCS not receiving ART'}, 'identificationModule': {'nctId': 'NCT00264394', 'briefTitle': 'Cardiovascular Risk Factor Management in HIV Infection', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Basel, Switzerland'}, 'officialTitle': 'Efficacy of a Computerised Physician Reminder System to Control Cardiovascular Risk Factors in HIV-infected Patients Receiving Antiretroviral Therapy: A Nested Randomised Controlled Cluster Trial Within the Swiss HIV Cohort Study', 'orgStudyIdInfo': {'id': 'SNF 3345-062041 SHCS 480'}, 'secondaryIdInfos': [{'id': '480', 'type': 'OTHER', 'domain': 'Swiss HIV Cohort Study Registry'}, {'id': '480', 'type': 'OTHER', 'domain': 'Swiss HIV Cohort Study'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Updated CHD risk profiles', 'description': 'Provision of regularly updated CHD risk profiles', 'interventionNames': ['Behavioral: Updated CHD risk profiles']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Guidelines', 'description': 'Physicians received guidelines only', 'interventionNames': ['Behavioral: Guidelines']}], 'interventions': [{'name': 'Updated CHD risk profiles', 'type': 'BEHAVIORAL', 'otherNames': ['Computer assisted intervention to reduce CHD risk'], 'description': 'Provision of computer generated CHD risk profiles', 'armGroupLabels': ['Updated CHD risk profiles']}, {'name': 'Guidelines', 'type': 'BEHAVIORAL', 'otherNames': ['guidelines group'], 'description': 'provision of guidelines for CHD risk factor management only', 'armGroupLabels': ['Guidelines']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'CH-4031', 'city': 'Basel', 'state': 'Canton of Basel-City', 'country': 'Switzerland', 'facility': 'University Hospital Basel', 'geoPoint': {'lat': 47.55839, 'lon': 7.57327}}, {'zip': 'CH-1211', 'city': 'Geneva', 'state': 'Canton of Geneva', 'country': 'Switzerland', 'facility': 'Division des Maladies Infectieuses, Hopital Universitaire Geneve', 'geoPoint': {'lat': 46.20222, 'lon': 6.14569}}, {'zip': 'CH-1011', 'city': 'Lausanne', 'state': 'Canton of Vaud', 'country': 'Switzerland', 'facility': 'Division Maladies Infectieuses, Hopital Universitaire Vaudois (CHUV)', 'geoPoint': {'lat': 46.516, 'lon': 6.63282}}, {'zip': 'CH-9007', 'city': 'Sankt Gallen', 'state': 'Canton Saint Gall', 'country': 'Switzerland', 'facility': 'Departement Innere Medizin Kantonsspital St. Gallen', 'geoPoint': {'lat': 47.42391, 'lon': 9.37477}}, {'zip': 'CH-6903', 'city': 'Lugano', 'state': 'Canton Ticino', 'country': 'Switzerland', 'facility': 'Ospedale Civico Lugano', 'geoPoint': {'lat': 46.01008, 'lon': 8.96004}}, {'zip': 'CH-8091', 'city': 'Zurich', 'state': 'Canton Zurich', 'country': 'Switzerland', 'facility': 'Abteilung für Infektionskrankheiten & Spitalhygiene, Universitätsspital Zürich', 'geoPoint': {'lat': 47.36667, 'lon': 8.55}}, {'zip': 'CH-3010', 'city': 'Bern', 'country': 'Switzerland', 'facility': 'Klinik und Poliklinik für Infektiologie, Inselspital', 'geoPoint': {'lat': 46.94809, 'lon': 7.44744}}], 'overallOfficials': [{'name': 'Heiner C Bucher, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Basel Institute for Clinical Epidemiology University Hospital Basel'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital, Basel, Switzerland', 'class': 'OTHER'}, 'collaborators': [{'name': 'Swiss National Science Foundation', 'class': 'OTHER'}, {'name': 'Bristol-Myers Squibb', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
