Background
Hispanic cancer patients are underrepresented in clinical trials (CTs). Research suggests lack of knowledge and language barriers contribute to low accrual. Audiovisual materials offer advantages to Hispanic populations because they have high acceptability; are easy to disseminate; and can be viewed with family.
Purpose
Hispanic cancer patients and caregivers participated in focus groups to aid in developing a Spanish language audiovisual intervention. This project explored the feasibility of delivering the intervention in medical oncology clinics.
Methods
35 patients were randomized to either the intervention condition where they were given the audiovisual intervention (n=18); or a control condition where they were asked to read the National Cancer Institute's Spanish language brochure (n=17). Self-report data on knowledge, attitudes, and self efficacy for participating in a CT, intention to participate in a CT, and receptivity to CT information, were collected at two time points
Results
Knowledge in the intervention condition improved (p=0.06). Intention to participate in a CT remained positive in the intervention condition (p=0.484), but declined over time in the control condition (p=0.031). There were no statistical differences in attitudes or self-efficacy for making a decision to participate in a CT.
Limitations
Preliminary pilot data should be confirmed in a larger randomized control trial as the sample size was small. Although the patients randomized to the intervention group believed themselves to be willing to participate in a CT, this decision was hypothetical. Not all patients were being considered for enrollment in a CT which may have removed any fear or uncertainty from the situation. In addition, the study was conducted with a small sample of Spanish-speaking Hispanic cancer patients at a comprehensive cancer center in Florida. Thus, the results may not generalize to other populations.
Conclusion
The pilot showed feasibility to deliver an audiovisual intervention in medical oncology clinics. The audiovisual intervention increased Hispanic patients’ knowledge of CTs and positive intention to participate in a CT. An audiovisual may improve quality of care for Hispanic cancer patients who are eligible for CTs.
