Therapeutic Misconception about Research Procedures: Does a Simple Information Chart Improve Understanding?

In phase I trials, some biospecimens are used both for research and patient care and some for research only. Some research participants have therapeutic misconception, assuming all biospecimens are for patient care. This study's aim was to test if a simple information chart would improve understanding of nontherapeutic research procedures. A two-arm study was conducted. Participants in the control group (C) were asked whether biospecimens were for their care, for research only, or for both. The experimental group (E) was asked the same questions but provided with a study-specific information chart labeling the purpose of each biospecimen. One hundred one patients were interviewed. In both arms, understanding that pretreatment blood draws were for patient care and research was moderate (49% for C and 62% for E). Understanding that posttreatment blood draws were for research only was significantly higher in the experimental arm (16% for C and 44% for E; p = 0.002). Providing a simple information chart may help alleviate this aspect of therapeutic misconception.

Understanding Immunotherapy Terminology: An Analysis of Provider-Patient Conversations.

BACKGROUND: Immunotherapy terminology is complex and can be difficult for patients to understand, threatening informed consent. The aims of this exploratory study are to determine whether patients understand immunotherapy terminology and if the provider defining the term improves patient understanding. METHODS: Conversations between oncology providers and patients discussing immunotherapy were observed(n=39), and technical terms used were noted. With consent, patients were interviewed post-conversation to assess their understanding of these terms(n=39). Comparisons of the terms were conducted using chi-square tests, Fisher's exact tests, or ANOVA where appropriate. RESULTS: 'Immunotherapy' was the most difficult for participants to understand with 48.7% (19/39) correctly defining immunotherapy. 'Immunotherapy agents' was understood 53.8% (14/26) of the time. 'Immune system' was well understood (88.5%;23/26). Providers defined immunotherapy in 97.4% of conversations. There was no correlation between having immunotherapy defined in the conversation, and the likelihood of a correct definition (p=0.487). 'Immune system' was defined in 92.3% of conversations (n=26), and defining it in the conversation was correlated with increased patient understanding (p=0.009). CONCLUSION: Our results indicate that patients have difficulty understanding some immunotherapy terminology. Since patient understanding of key terminology is crucial for informed consent and patient care, it is essential to implement interventions to improve understanding.

Videos improve patient understanding of chemotherapy terminology in a rural setting.

BACKGROUND: It is critical patients understand the terms used to describe oncology treatments; however, even basic chemotherapy terminology can be misunderstood. Rural communities tend to have especially low levels of health literacy compared with nonrural communities. To address low health literacy in rural communities, this study tested rural participants' understanding of previously developed educational chemotherapy videos that were designed for an underserved urban population. Participants were also asked for feedback to determine if the videos could be improved. METHODS: Fifty English-speaking patients who reside in counties classified as rural according to the Rural-Urban Continuum Code designations (RUCC 4-9) participated in the study. Participants were asked to define 6 chemotherapy terms before and after viewing a short, animated video explaining the term in English. Rates of correct and incorrect definitions provided by participants were also compared with previously published results from an urban cohort. RESULTS: All participants had statistically significantly higher rates of correct definitions for all 6 terms following the video intervention. Palliative chemotherapy understanding improved the most (10% correct prevideo and 76% postvideo intervention). For each video, the majority of participants (77%-92%) suggested no changes to the videos. CONCLUSION: Given the prevalence of low health literacy in rural communities, it is important to have effective educational interventions to improve the understanding of basic oncology-treatment terminology. This study found that short, educational videos, originally designed for an underserved urban population, can significantly improve understanding of commonly misunderstood chemotherapy terminology in a rural setting as well. LAY SUMMARY: Chemotherapy terminology can be confusing to patients. Understanding can be especially difficult in areas with low health literacy, such as underserved urban and rural communities. To address this concern, previously developed short, animated videos describing basic chemotherapy terminology were found to improve patient understanding in an underserved urban setting. In this study, the videos were tested in a rural population and their effectiveness was established. Participants in the rural setting were significantly more likely to correctly define all 6 tested terms after watching the videos. Educational tools for high-need populations are essential to ensure patients can understand the treatment they receive.

Reassessing the measurement and presence of therapeutic misconception in a phase 1 setting.

BACKGROUND: Therapeutic misconception (TM) refers to research subjects' failure to distinguish the goals of clinical research from standard personal care. TM has traditionally been determined by questioning the patient about the research study's purpose. Recent research, however, has questioned whether TM is as prevalent as reported due to discrepancies between patient/researcher interpretations of TM questions. The authors have created an interview tool receptive to these advancements to more accurately determine the prevalence of TM. METHODS: Patients were questioned about the trial's purpose as follows: 1) "Is the trial mostly intending to help research and gain knowledge?," 2) "Is it mostly intending to help you as a person?," or 3) "Don't know." Participants were then asked what they thought this question was asking: A) "What my own intentions are for participating," B) "What the official purpose of the research study is," or C) "Not sure." A patient exhibited TM by answering that the official trial purpose was to help him or her. RESULTS: Patients (n = 98) had a mean age of 60 years, were mostly White (64%), had a combined family annual income ≥$60,000 (61%), and 49% had a college degree. Twelve of 98 patients (12%) definitely exhibited TM. This was much lower than the author's original finding of 68% in a similar cohort. Twenty-four of 98 patients (24.5%) were unclear about what one or both questions were asking and could not be categorized. CONCLUSIONS: Previously, a patient was thought to have TM if they answered that the purpose of the trial was to benefit to him or her. An additional query about how patients interpreted that question revealed only 12% definitely had TM. LAY SUMMARY: Therapeutic misconception (TM) refers to research subjects' failure to distinguish the goals of clinical research from standard personal care. TM signals a basic misunderstanding of the purpose of clinical research, threatening valid informed consent to participate in clinical trials. TM has traditionally been determined by questioning patients about their research study's purpose. Recent research, however, has questioned whether TM is as prevalent due to discrepancies between patient/researcher interpretations of TM questions. By developing an interview-tool receptive to these advancements, we report a lower TM estimate in the phase 1 setting (12%) than we found previously in a similar cohort (68%).
