HIV Epidemiology - Medical Monitoring Project (MMP)

The Medical Monitoring Project (MMP) is a U.S. Centers for Disease Control and Prevention (CDC)-funded study of people with HIV and AIDS, which has been conducted since 2005 in Los Angeles County and 25 other U.S. sites. MMP is the first research study since the HIV Cost and Services Utilization Study (HCSUS), conducted in the mid-1990's, to collect information from a nationwide representative sample of people receiving HIV care. MMP was designed by HCSUS investigators at the RAND Corporation, who are currently serving as consultants on this project.


The objectives of MMP are to use a population-based sampling method to collect information from HIV-infected persons in care on healthcare utilization, disease outcomes, and risk behaviors; monitor and calculate rates of opportunistic infections among HIV-infected persons; determine the prevalence of adverse events to medical therapy; determine the prevalence of resistant strains of HIV; assess the impact of behavioral determinants in access to care and in adherence to medical regimens for HIV-positive persons; improve prevention programs to prevent further HIV transmission; and improve services for those already infected. The primary goal of MMP is to identify a representative sample of HIV-positive persons in care in Los Angeles County in order to provide representative data for care and prevention planning in Los Angeles County.

Study Design:

This confidential study is cross-sectional in design and will survey persons reported with HIV/AIDS who are 18 years of age and older, live in Los Angeles County , and receive care at the selected sampled sites. The sampled provider sites will determine the method for contacting patients who are included in the patient sample. The HEP project staff will work in collaboration with sampled clinic staff to obtain Institutional Review Board approval prior to any data collection activities. Patients who agree to participate in MMP will be given informed consent and HIPAA documents to sign. Subsequently, participants will complete a 45 minute - 1 hour interview at a time and location that is convenient for the patients and their medical records will be abstracted. All MMP participants will receive a $25.00 stipend for the one-time interview. The study period (the time period for which patients will be interviewed and medical records will be abstracted) is calendar year 2005 through May 2009.
