D.C. Cohort Longitudinal HIV Study

Please note the new URL for this information: http://go.gwu.edu/dccohort

The DC Cohort is a longitudinal research project that will collect clinical data from approximately 10,000 consenting HIV-infected outpatients receiving care at fifteen large treatment clinics in the District of Columbia. The DC Cohort is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health (NIH).

The primary project goal is to improve the quality of care and treatment of HIV-infected patients at large clinics in the District of Columbia by:

  • Linking data from fifteen large treatment clinics to enable evaluation of HIV/AIDS care provided in the District of Columbia
  • Monitoring socio-demographic data, clinical status, and treatment regimens of HIV-infected patients in DC over time
  • Providing clinic sites with routine reports on their patient population that will enable them to benchmark and improve their standards of clinical care
  • Contributing to the research of emerging issues in the prevention, treatment, and long term effects of HIV/AIDS-infected persons.
  • Evaluating the impact of HIV screening and prevention programs in collaboration with the DC Department of Health

The project's scientific objectives are to contribute to the knowledge regarding HIV-infected patients and their treatment through:

  • Evaluating the outcomes of HIV treatment regimens over time
  • Examining resistance patterns over time in relationship to treatment patterns and patient characteristics
  • Assessing the extent and impact of co-morbidities, such as hepatitis, diabetes, lipidemia, and STDs, on clinical outcomes
  • Advancing research on emerging issues in HIV and its treatment

 

 

 

 

Participant Information

The DC Cohort is open to enrollment for patients receiving care for HIV at one or more of the fifteen participating clinics. In order to join the DC Cohort, patients must be at least 18 years of age. Patients who are minors can also join but they must either be consented by a parent or legal guardian or be teenagers seeking care independently. All patients must be able to understand and sign the informed consent form.

Participant FAQs

What is the DC Cohort?

The DC Cohort is a research project that is collecting health information on people who are receiving HIV care at clinics in the District of Columbia. The information collected will help HIV care providers find out more about HIV and its treatments with the goal of improving HIV care for patients not only in DC, but for patients everywhere.

What is a cohort?

A "cohort" is a group of people who have something in common and who are followed over time. The "cohort" in this research project includes HIV-infected persons who are getting care in clinics throughout DC.

Which clinics are involved in this research project?

Many of the main HIV care providers in DC are taking part in this research project including:

The DC Department of Health is also taking part in this research project.

Who is paying for and leading this research project?

The DC Cohort is being paid for by the National Institutes of Health (NIH) and is being run by the Department of Epidemiology and Biostatistics at The Milken Institute School of Public Health with the help of Cerner Corporation.

What do I have to do to be in this research project?

To be in this research project, you must be getting HIV care at one of the DC Cohort participating clinics, give your permission, and sign the consent form allowing researchers to confidentially combine your health information with information from thousands of other HIV-infected patients in DC.

You will not have to come to the clinic for extra appointments or visits. You can complete the consent process during your regularly scheduled appointment at the clinic.

Do I have to be part of this research project?

No, you do not have to be part of the DC Cohort if you do not want to be. Nothing about the care that you get at your clinic will change if you are not in this research project. However, we are encouraging all HIV-infected persons to be a part of this research project so that we can get a complete picture of HIV care in DC and find better ways to care for all HIV-infected patients.

Who will have access to information collected through this research project that could identify me?

Only the staff the clinic at which you are receiving care and at the DC Department of Health who already have this information will have access to it.

How will my information be kept private?

All information will be kept in a safe and secure computer database.

What if I change my mind after I decide to be a part of the research project?

You can change your mind at any time. If you decide to cancel your permission, you can get a withdrawal form from your clinic and give it to your health care provider. When you cancel, no additional information will be shared about you.

Do I have to pay or will I get paid if I am in this research project?

No, you do not have to pay and will not get paid if you are in this research project.

How can I join this research project?

Someone at the clinic where you are receiving care will ask you to join the DC Cohort. If you want to join, they can tell you more about it and answer any questions you might have. If you decide to join, they will review the consent form with you.

Who do I contact for more information?

For more information, please contact your health care provider at the clinic where you are currently receiving care.

Community Advisory Board

A Community Advisory Board (CAB) has been convened to provide input and guidance on aspects of the study protocols and procedures from the patient perspective. The CAB consists of a patient representative from each clinical site. The purpose and mission of the DC Cohort CAB is to:

  • Provide recommendations and feedback regarding recruitment, retention, and ethical issues associated with the study
  • Share patient perspectives on the study with the Cohort leadership
  • Make recommendations about how to communicate the outcomes of the study to the involved patient populations

Additionally, two members of the CAB serve as ad hoc members of the DC Cohort Executive Committee (EC) and are responsible for communicating and sharing information between the CAB and the EC.

Investigator Information

DC Cohort investigators are encouraged to develop ideas for analyzing both site-specific and Cohort-wide data. Please see the applicable forms pertaining to data access and publication.

Collaboration Process-Cohort-Wide Analysis

  1. Read the Collaboration Policies document. This document outlines the policies and procedures for obtaining, using, and publishing with DC Cohort data.
  2. Complete a Concept Sheet and Data Request Form. These documents succinctly outline the data needed to complete your analysis. If you are requesting analytic support, you must indicate this here. Completed forms should be submitted via e-mail to Dr. Amanda Castel at acastel@gwu.edu. Data sent to external requesters may be subject to de-identification and some data elements may not be available for such requests. Please see the Data Request Form for any limitations on data requests.
  3. The Concept Sheet and Data Request Form will undergo three separate, concurrent reviews. They are reviewed by the DC Cohort PI or her designee, by a member of the Publications Subcommittee for clinical relevance, and by a member of the DSCC for data availability and feasibility. This process may involve additional questions and/or requests for revisions prior to approval. Once finalized, all cohort-wide analyses are reviewed, approved, and prioritized by the DC Cohort. On average, this process can take 4-6 weeks from concept sheet submission to approval.
  4. Once approved, if you have requested analytic support, then you will be put in touch with the analyst assigned to your project and can begin regular communications to move forward with your analysis.
  5. If you have not requested analytic support, then you will need to complete a Data Use Agreement and Data Management Plan. The DSCC will create custom data sets fit to the specifications detailed in your Data Request Form. These will be sent to you along with accompanying documentation as soon as they are available.

Ad Hoc Requests for Internal Purposes

For internal requests such as grant proposals, clinical trials, etc. that involve site-specific data and can be confined to a count or list of available participants, an email request can be sent to Amanda Castel at acastel@gwu.email.edu. If it is determined that the request is lengthy in nature or rises to the level of an analysis, then it may be determined that a concept sheet and data request form may be required following the processes described above.

Publication

In order to ensure that all products meet the standards and specifications of the DC Cohort, prior to submission to either a journal, meeting, conference, etc., your final product must undergo a review process. E-mail your final draft to Amanda Castel at acastel@gwu.edu along with all accompanying analytic code and your completed Data Analysis Plan. The DC Cohort Executive Committee reviews all abstracts, manuscripts, posters, etc., provides feedback to the authors, and approves final versions of cohort-wide analyses. Additionally, all analytic code for any analysis is reviewed by the DSCC. This process takes approximately 2-4 weeks, so please plan accordingly to allow sufficient time for review and approval prior to any submission deadlines.

The DC Cohort must be cited in all works. For manuscripts, the author line must end “on behalf of the DC Cohort Executive Committee.” Additionally, an acknowledgement section must list all participating DC Cohort members; click here for an updated acknowledgement list.
