Investigator/IRB-led community communication in genetic research: A descriptive feasibility pilot study

This pilot study, conducted in the Houston, TX, area, established a structured dialogue among a university Institutional Review Board, its researchers, and its local community members (i.e. pool of potential research participants) for the purpose of further educating all three parties about genetic research and community concerns related to such research. An IRB-designed educational presentation aimed at assisting potential subjects in making an informed decision to participate in genetic research was provided to four community groups (n=54); this presentation also included a current example of genetic research being conducted in the community as explained by the researcher, and a question-and-answer session designed to assist the IRB and the researcher in understanding the community's concerns about genetic research. Comparisons of pre- and post- presentation community questionnaires indicate that the joint presentation was effective in increasing community knowledge about genetic research, most notably related to the risks and benefits of this research to the individual, as well as the understanding that protections are in place for research participants. While researchers are optimistic about the idea of a collaborative effort with the IRB and the community, the feasibility of such a program and the benefit to the participating researchers remain unclear; additional research is necessary to establish the most effective method of communication for all groups involved, as well as to obtain statistically significant results with regard to race/ethnicity, gender, and education levels of community participants. ^

Determinants of patients' expectations about total knee arthroplasty outcomes

Knee osteoarthritis (OA) is the most prevalent form of arthritis in the US, affecting approximately 37% of adults. Approximately 300,000 total knee arthroplasty (TKA) procedures take place in the United States each year. Total knee arthroplasty is an elective procedure available to patients as an irreversible treatment after failure of previous medical treatments. Some patients sacrifice quality of life and endure many years of pain before making the decision to undergo total knee replacement. In making their decision, it is therefore imperative for patients to understand the procedure, risks and surgical outcomes to create realistic expectations and increase outcome satisfaction. ^ From 2004-2007, 236 OA patients who underwent TKA participated in the PEAKS (Patient Expectations About Knee Surgery) study, an observational longitudinal cohort study, completed baseline and 6 month follow-up questionnaires after the surgery. We performed a secondary data analysis of the PEAKS study to: (1) determine the specific presurgical patient characteristics associated with patients’ presurgical expectations of time to functional recovery; and (2) determine the association between presurgical expectations of time to functional recovery and postsurgical patient capabilities (6 months after TKA). We utilized the WOMAC to measure knee pain and function, the SF-36 to measure health-related quality of life, and the DASS and MOS-SSS to measure psychosocial quality of life variables. Expectation and capability measures were generated from panel of experts. A list of 10 activities was used for this analysis to measure functional expectations and postoperative functional capabilities. ^ The final cohort consisted of 236 individuals, was predominately White with 154 women and 82 men. The mean age was 65 years. Patients were optimistic about their time to functional recovery. Expectation time of being able to perform the list activities per patient had a median of less than 3 months. Patients who expected to be able to perform the functional activities by 3 months had better knee function, less pain and better overall health-related quality of life. Despite expectation differences, all patients showed significant improvement 6 months after surgery. Participant expectation of time to functional recovery was not an independent predictor of capability to perform functional activities at 6 months. Better presurgical patient characteristics were, however, associated with a higher likelihood of being able to perform all activities at 6 months. ^ This study gave us initial insight on the relationship between presurgical patient characteristics and their expectations of functional recovery after total knee replacement. Future studies clarifying the relationship between patient presurgical characteristics and postsurgical functional capabilities are needed.^
