Abstract

This study presents the data gathered from surveying 187 individuals and compares the answers to two questions using religion and education as qualifiers. Individual patients were surveyed at four different Family Practice clinics and completed surveys were collected and data was analyzed. The mean, median, and mode were taken for two questions regarding possible available information sources during clinical trials questions 2L3 and 2L6 (Appendix 1). Each question allowed survey takers to select from 0 to 4. Further statistical analysis was done to see possible differences in choice based on religion and level of education from questions 3P and 3S (Appendix 1).Religious choices were summarized into two possibilities as was level of education. Student t-tests were done to ascertain whether or not significant differences were present. For question 2L3 the mean was found to be 3.49, the median was found to be 3 and the mode was found to be 4. For question 2L6 the mean was found to be 2.75, the median was 3 and the mode was 4. The t-tests found that there were no significant differences between Christian and non-Christian and between having less than four years or college and four years of college or more.

The Influence of Education and Religion on the Perceived Benefit of Two Resources for Enrollment in Clinical Trials

Background

As innovations in medicine become more and more common, the practice of conducting clinical trials does as well. There is however an imbalance in said studies regarding the diversity of enrollees (Ciuliano et al. 2000). Women as well as those of a minority race often do not participate in clinical trials in correct numbers to accurately represent the population. These disparities result from influences they may stem from the patient or the provider. Many studies have been done regarding how race and gender factor into recruitment for trials (Noah, 2003; Murphy, Krumholz, & Gross, 2004; Coakley, Fadiran, Parrish, Griffith, Weiss, & Carter 2012). Often patients are afraid of trials and prefer not to take part. Doctors have been found to select preferentially for their trials as well. However, much less attention has been placed on other demographic factors such as education and religious belief. This is what the study incorporates in part; to understand what previously ignored factors may be truly important.

An important factor in whether or not patients are willing to participate in clinical trials is availability of resources. After experiments such as the Tuskegee Syphilis study, there are many people who approach clinical trials warily especially African Americans (Corbie-Smith et al. 1997). Having different forms of resources available affects whether or not some people are willing to enroll in a clinical trial. Possible resources include brochures, DVDs, support groups, and translated materials. Learning more about the procedures involved in clinical research increases knowledge and often promote enrollment in trials (Butler, 2007). The study includes two other resources; the availability of a former clinical trial enrollee and whether or not there is a medical interpreter. From this, further steps are taken to utilize the previously mentioned demographics and compare their choices.

Methodology

Surveys were handed out by summer research scholars at 4 locations, Bethlehem Family Medicine, Community Health and Wellness Center, Lehigh Valley Family Center, and Lehigh Family Medicine Associates. The surveys were available in both English and Spanish. Chinese surveys in both traditional and simplified were also created but none were yet collected. Patients 18 years of age and older were asked to participate in this survey that also served as consent. Eligible participants were limited to patients of the practices. This survey was purely voluntary, refusal was permitted and acceptance or refusal was documented. In total, 198 surveys were collected from the four locations. Omitting surveys with too multiple incomplete portions, 187 were used for analysis. The mean, median, and mode were found for the questions regarding contact with a former participant and availability of a medical interpreter. The data for the questions was then further analyzed based on answers to the questions regarding level of education and religious beliefs. T-tests were done after categorizing the education choices into reaching less than 4 years of college and reaching 4 or more years of college. The religious beliefs were grouped into the broad categories of Christianity and Other. The T tests were then applied to determine if any significant differences existed when comparing the answers to the questions by the two different groups.

Results

The mean, median, and mode for the results of the 2L3 regarding the benefit of having the opportunity to speak to a past enrollee and 2L6 regarding the benefit of having a medical interpreter are shown below in Table 1. Figure 1 and Figure 2, show the level of education and religious beliefs held by participants respectively.

When the answers were analyzed they were categorized into two answer groups, less than two indicating that the topic would be of no help, and two or greater which indicates that it would help. The number of patients who took the survey and answered question 2L3 (Appendix 1) in the categories are tabulated below in Table 2. The data was further analyzed and separated into those who had reached less than 4 years of college education (8th grade or less, some high school, high school graduate or GED, and some college or 2 year degree) and those who had reached at least 4 years of college education (4 year college graduate, more than a four year college degree, masters degree, professional degree, or doctoral degree). Similarly the data was also looked at in terms of choices of religion. The religious groups were categorized into Christian covering Catholic, Evangelical, Pentecostal, Jehovah's Witness, and Protestant or Other covering Buddhist, Hindu, Jewish, Muslim, non religious, and other religions.

Tabulated below in Table 4 are the results of a T-Test done on answers for question 2L3 chosen by those who had reached than 4 years of college education and those who had at least 4 years of college education. Whether or not there is significance between the two sets of data is shown below. Also included are the answers of those who are Christian or belong to the Other category evaluated in the same fashion. T-tests were unpaired, two tailed, with unequal variance, and utilized a 95 percent confidence value.

Conclusion

The results show that on average people feel that having the chance to meet a person who had taken part in a clinical trial would be more influential in helping them decide to take part in a clinical trial when compared with having the aid of a medical interpreter.

Though the study is limited to the population of the four clinics, the data shows that in general people feel more comfortable talking about the experience with someone who was inside the clinical research trial process than having someone trained to interpret the medical data. This depicts the distrust that still exists between the enrollee and the medical professionals. As mentioned before Tuskegee remains a firm memory, particularly in the minority population. Increasing the number of opportunities to interact with past enrollees would help increase recruitment numbers as the prospective participants become more confident and comfortable with clinical trials. While having a medical interpreter was ranked below meeting a past participant in ability to help decide patients to enroll in clinical trials, it was still rated as beneficial in helping decide whether or not to participate. Again, a deeper understanding of the trial fosters comfort and willingness to join. It should be noted that the majority of people chose 4 for both questions indicating that the resource in the inquiry would play a large part in helping the participant join a clinical trial. Furthermore, the T-Tests show that although they are considered factors in clinical trial enrollment, religious beliefs and education have no significant differences when comparing the answers found by separating each category into two different groups.

While this data seems to contradict the idea that these two factors are in fact influential to choosing whether or not a person will enroll, it must be taken into consideration that these two questions in general do not rely on religion or education. The acceptance or desire for information is not affected by what level your education is. While it is possible that religious beliefs may stop a person from taking part in a trial, unless their religion prohibited obtaining information it is unlikely that it will factor into a person’s opinion on what is helpful in convincing them of joining a trial. Similarly, a basic understanding of the trial is needed, which can be obtained with increased learning. However, it is also unlikely that a person’s level of education will influence whether or not they wish to obtain further information. While this particular sample did not show the influence of education level and religion, the willingness to enroll is very often affected.

A limitation to this study can be seen in the fact that only four clinics were selected to participate and were located in close vicinity to each other. While a total of 400 surveys were desired, the goal has not yet been reached thus limiting the population further. The limited population may have skewed the results as less opportunity was available for trends to become significant. Another limitation is that not all surveys were answered completely, further changing the results. The study looked at religion and education but missing answers from minority groups in both categories cause even less distinction to appear when analyzed using a T-test. Because this study is a subdivision of another broader study there are many parts that will be covered. Future research could add an additional question such as whether or not having a contract explicitly stating the processes that will occur will help participants decide to enroll. The contract would serve to hold the doctors to standards and allay issues that the patient may have towards possible deviations from what they had signed up for. Yet another opportunity for further research lies in location, specifically by increasing the number of clinics all over the United States from the east to west coast. The different areas with different populations to pull from would give a chance for any underlying trends to be seen.
