Practicing HIV/AIDS community-based research.

Although community-based research (CBR) is gaining popularity, especially within the field of HIV/AIDS research, there is a paucity of practical models or frameworks designed to guide researchers and community members. Within the present paper the author presents a ten-stage model of conducting CBR that emerged from two HIV/AIDS CBR studies that were conducted in Alberta, Canada. The main strengths and challenges to conducting HIV/AIDS CBR are also explored. Living a life with HIV has changed dramatically over the past few decades. There have been notable improvements in medical technology and treatment, resulting in increased quality and duration of life (Volberding, 1998; Wong-Staal, 1997) as well as improvements in psychosocial interventions leading to improved mental health services (Grinstead & Van Der Straten, 2000; Hoffman, 1996; Sarwer & Crawford, 1994; Schaffner, 1994). Perhaps most significant has been the astonishing community rallying and social support networks that have occurred among individuals living with HIV and AIDS (Roy & Cain, 2001). People living with HIV and AIDS have demonstrated their resilience and positive outlooks through developing a multitude of community connections and projects. These organizational groups have engaged in HIV peer counselling at community-based organizations, fund raising programs, board involvement in community agency organizations and HIV/AIDS national committees, as well as volunteer work in many settings. There has also been a recent focus on CBR, which includes having individuals living with HIV and AIDS, people vulnerable to HIV infection or other stakeholders in HIV/AIDS issues become partners in research projects with academic or trained researchers (Health Canada, 2002).

An elapsed time-temperature monitor for blood storage.

Blood should not be allowed to exceed 10 C while being stored or transported. However, one cannot test the internal temperature of a unit of blood without contaminating it. Most blood banks have established an arbitrary time limit beyond which a blood unit cannot be kept out of the refrigerator. This method is ineffective if blood is stored in a satellite refrigerator, since the blood may be moved in and out of the refrigerator and the blood bank personnel will be unaware of it. An elapsed time indicator is described which employs a small condenser (E-Cell-Plessey Electronics) charged with a known amount of electricity. If the device is removed from the refrigerator, it begins to discharge at a known rate. The amount of time subsequently can be determined by the loss of charge. The prototype of this instrument has been found to be quite accurate and small (2 inches X 2 inches X 1 inch). It would be rather inexpensive if made in considerable numbers.
