Behavioral and clinical characteristics of persons receiving medical care for HIV infection — medical monitoring project, United States, 2009 ; MMWR. Surveillance summaries : Morbidity and mortality weekly report. Surveillance summaries

Problem: As of December 31, 2009, an estimated 864,748 persons were living with human immunodeficiency virus (HIV) infection in the 50 U.S. states, the District of Columbia, and six U.S.-dependent areas. Whereas HIV surveillance programs in the United States collect information about persons with a diagnosis of HIV infection, supplemental surveillance systems collect in-depth information about the behavioral and clinical characteristics of persons receiving outpatient medical care for HIV infection. These data are needed to reduce HIV-related morbidity and mortality and HIV transmission. ; Reporting Period Covered: Data were collected during June 2009–May 2010 for patients receiving medical care at least once during January–April 2009. ; Description of the System: The Medical Monitoring Project (MMP) is an ongoing surveillance system that assesses behaviors and clinical characteristics of HIV-infected persons who have received outpatient medical care. For the 2009 data collection cycle, participants must have been aged ≥18 years and have received medical care during January–April 2009 at sampled facilities that provide HIV medical care within participating MMP project areas. Behavioral and selected clinical data were collected using an in-person interview, and most clinical data were collected using medical record abstraction. A total of 23 project areas in 16 states and Puerto Rico were funded to collect data during the 2009 data collection cycle. The data were weighted for probability of selection and nonresponse to be representative of adults receiving outpatient medical care for HIV infection in the United States and Puerto Rico. Prevalence estimates are presented as weighted percentages. The period of reference is the 12 months before the patient interview unless otherwise noted. ; Results: The patients in MMP represent 421,186 adults who received outpatient medical care for HIV infection in the United States and Puerto Rico during January–April 2009. Of adults who received medical care for HIV infection, ...
