Development of a City-Wide Cohort of HIV-Infected Persons in Care in the District of Columbia: The DC Cohort

All major community and academic clinics treating HIV-infected persons in the District of
Columbia (DC) will initially be included in the development of a city-wide "DC Cohort" of
HIV-infected persons in care, with consideration to be given subsequently to the inclusion of
large private physician practices. Socio-demographics, risk factors, treatments, diagnoses,
labs and procedures documented in outpatient medical record systems will be included in the
DC Cohort database. Routine reports will be generated every six months for sites comparing
their participants' socio-demographics, clinical status, treatments, and outcomes to all
other data in the DC Cohort database, and other comparisons specifically requested by sites.
All sites will be provided analytic support in research areas of interest.

Inclusion Criteria:

- Patient is receiving care for HIV at one or more of the twelve participating clinics
in the DC Cohort.

- Patient is either age 18 years or older, or seeks HIV care independently and is able
to understand and sign informed consent.

- Patient is a minor who is consented by a parent or legal guardian.

Exclusion Criteria:

- Patient is unable or refuses to provide informed consent.

- Minor children ages 12 through 17 who are unaware of their HIV status
