During 1994 and 1995, a two-stage sampling method was used to recruit a cohort that would be representative of HIV-positive adults (age 20+ years) who were aware of their positive HIV serostatus. For the first stage, 50 recruitment sites were randomly selected from a sampling frame of 341 medical and social service agencies known to serve an adult clientele and to have HIV case loads of 20 or more. For the second stage, a sample of HIV positive clients were recruited from 43 of the sites either through random selection from a client list prepared by agency staff, or through onsite, sequential enrollment. To complete the CHAIN longitudinal cohort, HIV-positive individuals unconnected to medical care and case management services at the time of the interview were also recruited to supplement the agency-based sampling strategy. These "unconnected" individuals were contacted at outreach sites and through acquaintance sampling from among enrolled CHAIN participants. Baseline interviews were completed with 648 HIV+ individuals from the agency sites and 52 HIV+ individuals unconnected to services. Cohort attrition has remained low. Among CHAIN participants alive and still living in NYC, survey completion rates were in excess of 80 % and exceeded 90 percent for 4 of the 7 follow-up rounds of interviews. Individuals lost to follow-up over the course of study showed few differences when compared with those who continued to participate.
In 2002, at the direction of the Planning Council, Columbia researchers recruited an entirely new cohort of 693 HIV+ adults residents of New York City, following the same methodology used for the original CHAIN cohort. The CHAIN "new cohort" study began enrolling clients in July, 2002 and closed enrollment in December, 2003. A total of 684 HIV positives in care, and 9 persons living with HIV unconnected to care were recruited and interviewed. The two rounds of follow-up interviews have completed by 2006.
In addition to the New York City cohort studies, the CHAIN program of research was extended to three northern suburban counties, Putnam, Rockland, and Westchester counties. Using the same methodology of sampling, Tri-County CHAIN recruited a cohort of 398 adults in the 2001 and 84 refresher cohorts during 2005 and 2006, and four rounds of interviews have completed by 2006. The same core measures are being used which allow cross-cohort as well as cross time comparisons. A fifth round of Tri-County interviews is to commence during the fall of 2007.
CHAIN interviews, take approximately two hours to complete, and are conducted in person by trained community interviewers who were matched to respondents as much as possible with regard to gender and race/ethnicity. Approximately 10% of interviews are conducted in Spanish. Several members of the field staff are themselves HIV positive. Major interview topic areas include: (1) need for health and social services, (2) access, utilization and satisfaction with health and social services, (3) sociodemographic characteristics, (4) housing and other aspects of living situation; (5) sex and drug risk behaviors; (6) informal caregiving from friends, family and volunteers, and (7) their quality of life with respect to health status and psychological and social functioning. A number of items have been added over the years related to antiretroviral therapies, specific medical care services, viral load levels, and other topics of interest to policymakers, planners, providers, and clients on the CARE Act Title A Planning Council. Follow-up interviews are conducted at annual intervals.
Each year CHAIN researchers produce a series of reports for the New York HIV Planning Council responding to the questions, interests, and priorities of the Council and its workgroups, the NYC Department of Health and Mental Hygiene (DOHMH) Office of AIDS Policy Coordination, and provider and consumer communities.. To date, over 100 reports have been written examining a range of topics with focus on unmet health and social service needs, trends in service utilization, and various outcomes among the CHAIN cohort. All CHAIN reports are available at no cost and widely distributed.
A Technical Review Team (TRT) provides oversight for the CHAIN Project in New York City and in the Tri-County. In addition to Peter Messeri, PhD and Angela Aidala, PhD of Columbia University's Mailman School of Public Health, TRT is consists of representatives from Medical and Health Research Association (MHRA), NYC DOHMH, Westchester County Department of Health, and New York City Office of AIDS Policy.
The CHAIN program of research has been made possible by grants from the US Health Resources and Services Administration (HRSA) HIV/AIDS Bureau. The CHAIN study is supported by the HIV Health and Human Services Planning Council of New York under a Title A grant of the Ryan White CARE through the New York City Department of Health and Mental Hygiene. CHAIN is conducted under the auspices of the Medical and Health Research Association of New York City, Inc, and the Westchester County Department of Health. In addition to the work done on behalf of the Planning Council, CHAIN researchers have conducted special studies funded by the Health Resources and Services Administration (HRSA) HIV/AIDS Bureau and the Centers for Disease Control and Prevention.
Below is a complete list of CHAIN documents since the study's inception in 1994. Not all of the studies are available electronically. The studies that are available are underlined and link to a pdf* version of the document.
