DC Cohort Longitudinal HIV Status Neutral Study

The primary project goal is to contribute to improving the quality of care and treatment of people receiving HIV prevention services and HIV care at clinics in the District of Columbia by:

  • Linking data from multiple treatment sites to enable evaluation of HIV prevention services and HIV care provided in the District of Columbia
  • Monitoring socio-demographic data, clinical status, and treatment regimens of people receiving HIV prevention services or HIV care in DC over time
  • Providing clinic sites with routine reports on their patient population that enables 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 people both living with HIV and those receiving HIV prevention services
  • Evaluating the impact of HIV screening and prevention programs in collaboration with the DC Department of Health
  • Creating a resource to facilitate additional HIV research and assist in identifying patients for research studies

The project's scientific objectives are to contribute to the knowledge regarding people receiving HIV prevention services and HIV treatment through:

  • Evaluating the outcomes of HIV medications for prevention and treatment over time
  • Examining HIV resistance patterns over time in relationship to treatment patterns and patient characteristics among people diagnosed with HIV
  • Assessing the extent and impact of co-morbidities, such as hepatitis, diabetes, lipidemia, and Sexually Transmitted Infections (STIs), on clinical outcomes among people diagnosed with HIV compared to those at higher likelihood of acquiring HIV
  • Advancing research on emerging issues in HIV Prevention and HIV disease and its treatment

Participant Information

The DC Cohort is open to enrollment for patients receiving prevention services or care for HIV at one or more of the fourteen 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. Consent forms are available in multiple languages including English, Spanish, French, Amharic, Chinese, Korean, and Vietnamese.

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 prevention services or HIV care at clinics in the District of Columbia. The information collected will help healthcare providers find out more about HIV prevention and HIV treatment with the goal of improving HIV prevention services and 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 people with or without HIV who are receiving prevention services or HIV 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 (DEPI) and the Biostatistics Center (BSC) at The Milken Institute School of Public Health.

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

To be in this research project, you must be getting HIV prevention services or receiving HIV care from at least 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 persons getting care 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 persons with or without HIV to be a part of this research project so that we can get a complete picture of HIV prevention services and HIV care and treatment in DC and find better ways to care for all persons.

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 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 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. If you are asked to participate in certain substudies of the DC Cohort, you may be offered an incentive.

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 patient representatives from each clinical site. The 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 DC 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.

Interested in joining the Community Advisory Board (CAB)?

If you would like to provide community feedback on research related to the care of people who receive HIV prevention services or HIV care at one of our participating sites, you may be eligible to join the DC Cohort CAB. The purpose of our CAB is to: 

  • Build a relationship between researchers and the community
  • Receive regular updates on the DC Cohort study progress
  • Provide community perspectives and guidance on new research

Please contact James Peterson at [email protected] or Shannon Hammerlund at mailto:[email protected]. We keep all calls and correspondence confidential. CAB attendees will receive a small stipend.

Research Collaboration Opportunities

The DC Cohort welcomes collaboration with authorized internal and external users of the data to allow for a broad spectrum of data and research purposes.

WHO IS AUTHORIZED TO USE DC COHORT DATA?

  1. DC Cohort Site Principal Investigators (PIs)
  2. Staff or fellows at a participating DC Cohort site 
    1. Must be sponsored by a DC Cohort Site PI
  3. Members of the DC Cohort Data and Statistics Coordinating Center (DSCC)
  4. Members of the DC Center for AIDS Research (CFAR)
    1. After discussion with the DC Cohort Site PI
  5. GW Staff
    1. Must be sponsored by a DC Cohort staff member
  6. GW Students 
    1. Must be sponsored by a DC Cohort GW faculty member
    2. Must utilize the data for the purposes of meeting educational research requirements (e.g., Master's theses or Doctoral dissertations) 
  7. Outside investigators who are sponsored by a DC Cohort Site PI or an authorized member of the DSCC

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. This document succinctly outlines the data needed to complete your analysis. If you are requesting analytic support, you must indicate this here. Your completed Concept Sheet should be submitted via e-mail to Dr. Amanda Castel at [email protected]. Data sent to external requesters may be subject to de-identification and some data elements may not be available for such requests. 
  3. The Concept Sheet will undergo three separate, concurrent reviews. They are reviewed by the DC Cohort PI or her designee, members of the DSCC, and by a DSCC analyst 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 are part of an outside entity receiving DC Cohort data, then you will need to complete a Data Use Agreement and Data Management Plan. The DSCC will create custom data sets fit to your specifications. These will be sent to you along with accompanying documentation as soon as they are available.
Please note that once the concept sheet is approved, it takes approximately 4-6 weeks to receive the data.

 

COLLABORATION PROCESS: SITE-SPECIFIC 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. This document succinctly outlines the data needed to complete your analysis. If you are requesting analytic support, you must indicate this here. Your completed Concept Sheet should be submitted via e-mail to Dr. Amanda Castel at [email protected]. Data sent to external requesters may be subject to de-identification and some data elements may not be available for such requests. 
  3. The Concept Sheet will undergo two separate, concurrent reviews. They are reviewed by the DC Cohort PI or her designee for clinical relevance and by a DSCC analyst for data availability and feasibility. This process may involve additional questions and/or requests for revisions prior to approval. Once finalized, site-specific analyses are forwarded to the Executive Committee for their awareness.  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. Please note, due to limited resources, cohort-wide analysis will have prioritization for analytic support from the DSCC.
  5. If you are part of an outside entity receiving DC Cohort data, then you will need to complete a Data Use Agreement and Data Management Plan. The DSCC will create custom data sets fit to your specifications. These will be sent to you along with accompanying documentation as soon as they are available.
Please note that once the concept sheet is approved, it takes approximately 4-6 weeks to receive the data.

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 [email protected]. 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 [email protected] 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; see the "Investigator Information" section above for an updated acknowledgement list.
