  • No healthy volunteers
  • Adult, Older adult

Study population: The study population will consist of adults (>18 years of age) with and without HIV infection continuously enrolled for at least 12 months in the Integrated Health Care Information Services (IHCIS) National Managed Care Benchmarked Database, a health insurance claims database, during the interval between January 1, 1997 and March 31, 2008, and with continuous eligibility for pharmacy benefits. Health plan enrollees in this database are located in the continental US

Who may be able to join

  • The inclusion criteria was continuous enrollment for at least 12 months in the Integrated Health Care Information Services (IHCIS) National Managed Care Benchmarked Database during the interval between January 1, 1997 and March 31, 2008, age 18 years of age and older, and continuous eligibility for pharmacy benefits during IHCIS enrollment.

Who cannot join

  • Exclusion criteria were membership in the Integrated Health Care Information Services (IHCIS) National Managed Care Benchmarked Database without a valid gender or age record, less than 12 months continuous enrolment, and member residence in the 'national' census region. This latter grouping represented members who were either not living in the continental US or were masked for confidentiality reasons based on IHCIS archiving of data per the Health Insurance Portability and Accountability Act.

About this study

Official title: Fractures Over Time Stratified by HIV Infection and Antiretroviral Therapy (ART) Exposure

This US population-based study will explore the incidence of and risks for fracture among adults with and without human immunodeficiency virus (HIV) infection. The objectives are to determine the incidence of fracture among persons with and without HIV infection, compare risk factors for fracture among persons with and without HIV infection, and to examine the associations of antiretroviral (ARV) treatment exposure for incidence and risk of fracture among persons with HIV infection.

Read the detailed description

This study uses data from the Integrated Health Care Information Services (IHCIS) National Managed Care Benchmarked Database, a health insurance claims database. The study has two analytic components. The first is a retrospective cohort study comparing subjects without HIV infection to subjects with HIV infection for the incidence of and risk for fracture, including the use of anyARV drugs in persons with HIV infection. The second is a nested case-control study limited to persons with HIV infectiion within the cohort. Cases are those with incident fractures occurring after the diagnosis of HIV infection, and controls those without a fracture. Cases and controls will be compared for risk factors for incident fracture including ARV drug exposure. The drug exposures will include individual nucleoside reverse transcriptase inhibitors (NRTIs) (as permitted by sample size) and the other ARV drug classes.

ViiV Healthcare is the new sponsor of this study, and GlaxoSmithKline is in the process of updating systems to reflect the change in sponsorship.

Study groups in NCT01077557
Study groupRoleWhat they receive
No HIV infectionSubjects without HIV infection (Group 1) are adults, 18 years of age and older, continuously enrolled for at least 12 months in the Integrated Health Care Information Services (IHCIS) National Managed Care Benchmarked Database, a health insurance claims database, during the interval between January 1, 1997 and March 31, 2008, and with continuous eligibility for pharmacy benefits. A 3:1 match of subjects without HIV infection to a subject with HIV infection will occur. Each member of the comparator group without HIV infection will be matched on gender, month/year of IHCIS enrolment, and duration of enrollment to the respective study subject with HIV infection.
Receives: Other: No Antiretroviral (ARV) Drug Exposure
HIV infection with no antiretroviral (ARV) drug exposureHIV infection with no ARV drug exposure (Group 2) represents adults, 18 years of age and older, continuously enrolled for at least 12 months in the Integrated Health Care Information Services (IHCIS) National Managed Care Benchmarked Database, a health insurance claims database, during the interval between January 1, 1997 and March 31, 2008, and with continuous eligibility for pharmacy benefits. HIV exposure will be identified by ICD-9-CM code 042 or v08 in one or more diagnostic fields. This group will have no pharmacy dispensing for ARV drugs.
Receives: Other: No Antiretroviral (ARV) Drug Exposure
HIV infection with ARV drug exposureHIV infection with ARV drug exposure (Group 3) represents adults, 18 years of age and older, continuously enrolled for at least 12 months in the Integrated Health Care Information Services (IHCIS) National Managed Care Benchmarked Database, a health insurance claims database, during the interval between January 1, 1997 and March 31, 2008, and with continuous eligibility for pharmacy benefits. HIV exposure will be identified by ICD-9-CM code 042 or v08 in one or more diagnostic fields. This group will have at least one pharmacy dispensing for an HIV antiretroviral drug.
Receives: Drug: Any Antiretroviral (ARV) Drug Exposure

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incident fracture defined by first ICD-9-CM code 733.1 or 800-829 during the follow-up period. Inclusion is restricted to four-digit codes for closed fracture. Exclusions will be codes for skull, face, chest, rib, open fracture, and crushing injuries

    Measured: From enrollment in IHCIS National Managed Care Benchmarked Database to whichever of the following three event dates comes first: date of first fracture, end date of IHCIS enrollment, or March 31, 2008

Questions about this trial

What is this clinical trial studying?

An observational study of Fracture and Infection, Human Immunodeficiency Virus, run by ViiV Healthcare.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incident fracture defined by first ICD-9-CM code 733.1 or 800-829 during the follow-up period. Inclusion is restricted to four-digit codes for closed fracture. Exclusions will be codes for skull, face, chest, rib, open fracture, and crushing injuries (time frame: From enrollment in IHCIS National Managed Care Benchmarked Database to whichever of the following three event dates comes first: date of first fracture, end date of IHCIS enrollment, or March 31, 2008). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2017.
