To determine public attitudes towards emergency research, exception from informed consent ( EFIC) and a specific proposed clinical trial using EFIC.
As part of a planned community consultation activity, a survey was conducted at a popular public venue. Participants answered demographic questions and then were asked their opinions on specifically described consent circumstances in emergency research, including the proposed EFIC trial. Multiple logistic and linear regression were used to determine respondent characteristics associated with specific attitudes.
1901 surveys were completed, The majority of respondents supported emergency research (88%) and the concept of surrogate consent by a legally authorized representative ( 78%). The concept of EFIC was less well supported ( 35%) but the application of EFIC was more accepted. especially when EFIC was applied to the respondent themselves ( 51%). The community believed the proposed EFIC study was acceptable ( 82%); a minority had concerns but most were related to patient safety and not to EFIC. Respondents with less education and lower incomes were less likely to express opinions about the consent and research concepts described.
emergency research and the proposed EFIC trial is supported in this community. The concept of EFIC is less well supported but is more acceptable when a specific trial is described or when respondents consider EFIC for themselves. Specific respondent characteristics are associated with attitudes about research; this can assist in development of meaningful community consultation activities.
One of the regulatory requirements for research using the emergency Exception from Informed Consent ( EFIC) is community consultation with members of the community in which the research is to be performed and members of the community of potential research subjects if those communities are not the same. The nature, content and intensity of community consultation is not completely prescribed by federal regulations, in order to allow site specific application. However , community consultation must include a two- way communication, in which the communities are educated to the content of the EFIC study, and the meaning and need for EFIC .
Although community consultation is not meant to provide community consent or disapproval, the IRB is required, in its deliberations on the proposed EFIC study, to consider questions and concerns from members of the communities. In preparation for a national EFIC trial of pre-hospital interventions for status seizures, we developed a community consultation plan together with our IRB to reach a broad base of the general population of our state ( the community in which the research is to be performed) , as well as specific community members at risk for the disease under investigation ( the community of potential research subjects).
The current study was directed towards a broad population of Minnesotans. In addition to specific discussion of the planned EFIC trial, we also hoped to assess public attitudes towards research in general and emergency research in particular. We wanted to determine respondent characteristics associated with specific attitudes or understanding about research. We hoped to use this information to determine effective methods of community engagement for future EFIC research trials.
This was a survey of persons visiting the emergency medicine display located in the University of Minnesota education building at the Minnesota State Fair . Data were collected on three afternoons and evenings for a total of 13.5 hours, during August 2008. About 16,000 persons walk through the education building each day of the State Fair. It is a common location for the performance of surveys and health screening examinations. This study was reviewed and approved by the IRB at the University of Minnesota and the Human Subjects Research Committee at Hennepin County Medical Center. Because of its voluntary and anonymous nature , informed consent was waived. However, a cover page was included with the survey tool that provided an overview of the purpose of the study, details of the proposed EFIC trial, and contact information should questions subsequently arise.
The survey consisted of three parts; part one asked for demographic information, previous research exposure/ involvement and whether or not respondents knew of anyone ( including themselves) who had experienced seizures. Part two described the proposed pre-hospital study that would enroll seizing patients using EFIC. Respondents were queried about questions or concerns about the study, whether they believed it was valuable for our community, and whether EFIC enrollment would be personally acceptable for their own enrollment. Part three asked about the acceptability of research under various circumstances such as with or without surrogate consent, or with or without the possibility of direct patient benefit.
The survey was not previously validated but had been tested for readability and understanding with 38 undergraduate students ( data not included). Based on their assessment of the survey, no modifications were made. Categorical responses were available for demographic and personal characteristic questions; for questions asking for opinions , a five point Likert scale was used (1= strongly agree, 3= no opinion , 5= strongly disagree ).
Surveys were distributed by trained research associates ( RAs ) under the supervision of the research study team (i.e., the PI and research coordinators ) Respondents completed the survey in writing; the RAs were available to read the survey to the respondents if so desired. Questions about the survey, the seizure study and EFIC were encouraged, and directed to the research team.
Among other demographic information, respondents were asked to identify their religious denominations. Because of the small number of respondents classifying themselves into specific non- Christian denominations, the demographic category for religions was collapsed for analysis into Christian ( Catholic and protestant denominations ) and non - Christian ( Buddist , Muslim, Jewish ).
Data were analyzed using SAS 9.1 (SAS Institute Inc., Cary, N.C., USA). Bivariate analyses were evaluated with chi-square tests for proportions, student’s t-test for comparing means, and correlation coefficients for evaluating the associations between two continuous or approximately continuous variables. For multivariate analyses, where the dependent variable was dichotomous , we performed a logistic regression and for all others we used linear regressions
One thousand nine hundred and one persons participated ; the demographics of the respondent group are shown in Table One. All responses were self- reported; classification as rural or urban was based on zip codes and state definitions. The distribution of ages ,educational levels, and household incomes are listed in Table Two. Thirty five per cent of respondents knew someone who or themselves had experiences seizures.
Fifteen percent ( n= 290) had previously participated in a research study and 8 % ( n= 154) had previously refused to participate .The reasons for participation or refusal are listed in Table Three. One hundred and fifty respondents ( 8.1%) had previously provided consent for someone else ( a minor or other vulnerable relative) to participate in research.
Overall, respondents were supportive of medical research, and 88 % indicated that they believed research in emergency care was important ( 9 % had no opinion). Those with more education were more favorable towards emergency medical research ( p= .0090); those with a higher income and those who previously participated in research tended to be more supportive ( p= .0575 and .0642, respectively ).
The attitudes of respondents towards various consent concepts and associated respondent characteristics are show in Table Four. Respondents supported the concept of surrogate consent for research participation ; 78 % agreed or strongly agreed that it is acceptable for family members to provide consent for research participation when they themselves could not. Even when told that there would be no direct benefit from their enrollment into a research study, 65 % still would allow their family members to provide surrogate consent on their behalf.
Enrollment into emergency research without prospective consent was less strongly supported. When no specific study was described, only 35 % of respondents agreed or strongly agreed that it is acceptable to enroll patients into emergency research studies without consent ( Table four). If the respondents were told that the proposed EFIC research offered a direct benefit to the patient, 41 % agreed or strongly agreed that the research was acceptable without consent; older persons agreed less often ( p= .0391). If the EFIC study did not offer direct benefit but might help future patients, 38%% were supportive or strongly supportive. No specific demographic characteristic was associated with being supportive of research in this circumstance; those who were older or with more education tended to be less supportive ( p= .0573 and p= .0901 respectively ).
However, when the respondents were asked if it was acceptable that they personally be enrolled in an emergency EFIC research study when they themselves were too sick to give permission, 51 % agreed or strongly agreed . Table four shows respondent characteristics associated with specific attitudes on a persons’ own enrollment into an EFIC trial.
Related to the proposed EFIC seizure study , a large majority ( 82 % ) of respondents believed the study was valuable for our community. Respondent characteristics associated with specific attitudes regarding the proposed trial are shown in Table five. Overall, only 3 % of respondents had specific questions about the proposed EFIC trial. A number of themes emerged from among the questions and concerns stated by respondents ; these are categorized in Table Six.
The IRB was informed of the results of the survey and considered the survey responses as an adequate community consultation . No changes in the protocol or material related to EFIC were required by the IRB based on the results of the survey. The survey informed the development of public notification material; specific details of the protocol were expanded.
As part of community consultation targeting the population in which our planned EFIC trial will take place, we surveyed a large number of persons at a popular public venue, the Minnesota State fair. For the most part, the demographic characteristics of the study population reflect those of the state (Table One). Given the similarities between the state and study populations, we believe the opinions we gathered provide a reasonable representation of public attitudes of Minnesotans towards research. However, because of the relatively homogenous study group, we cannot generalize our findings to other specific population subgroups within the state, such as the growing population of ethnic and racial minorities. While the State fair data is valuable to discern public attitudes about research, EFIC and the proposed EFIC seizure study , it may be incomplete in other circumstances, such as for research involving an acute illness or injury that targets a different specific population ( for example, trauma in young adults in Minnesota).
Our data suggest an overall support of emergency research. This is consistent with other studies of pubic attitudes towards emergency research (1,2). Our respondents also were supportive of the proposed EFIC seizure study. Only a small number of respondents had questions or concerns about the proposed seizure trial, and most were related to clinical issues , such as patient safety, the drug approval process, and the study design . However, a quarter of those with concerns or questions were concerned about research ethics and/or EFIC . Concerns about patient safety and the risk- benefit ratio were commonly expressed by survivors of sudden cardiac death interviewed by Dickert, et. al ( 2) ; less concern was expressed related to randomization or the exception from consent. These concerns must be acknowledged and addressed by investigators, even if they represent a minority of concerns. Community consultation activities might be more able to engage the public to support the research process if detailed discussion and education about the clinical aspects of the proposed study are included, as well as research ethics and EFIC. This is further suggested by the observation that support of these research concepts was more apparent when more details were available ( ie. the specific study was described), and when it was known that a direct patient benefit was possible from study enrollment. Triner, et.al., ( 3 ) also found more acceptance of EFIC among emergency department ( ED) patients when the concept was described in the context of a specific trial. Richardson et.al., ( 4) found that focus group participants with negative attitudes about EFIC were strongly supportive of EFIC research trials described in specific scenarios. Longfield et.al, ( 5 ) reported that only 35 % of attendees to at community meetings supported the concept of research without consent in emergency circumstances, but 82% believed a described EFIC trial was valuable in the community.
The concept of EFIC itself was not as well supported among our respondents as other consenting circumstances. It is interesting to note that EFIC was less supported when respondents were asked to assume responsibility for deciding on the acceptability of EFIC for others, as compared to EFIC for themselves. McClure et. al, ( 6) found that only 49 % of a surveyed ED population ( n= 530, including 198 in Minnesota) supported the concept of EFIC, but 70 % felt it was acceptable that they themselves be enrolled in an EFIC trial. Kasner et.al.,( 7 ) found similar results in neurology patients. McClure has suggested that this phenomena may represent a simultaneous desire of patients to protect the public and an altruistic attitude towards those with critical illness and injury ( 6 ). The reluctance to support EFIC for others may also reflect uneasiness of an individual to speak on behalf of strangers. Careful consideration of what constitutes acceptable community representation needs to be included in the development of a community consultation plan ( 4 ) .
Certain respondent characteristics were associated with support or lack of support for the consent concepts included in the survey. For example, those with higher education or incomes were favorably inclined or tended to be favorable towards research in general and EFIC in particular, whereas those with less education and who were older were not supportive. In addition, we observed that women tended to be less supportive of many of the research concepts. Similar gender differences have been described ( 3 ). Although the gender difference in attitudes among our respondents did not usually reach statistical significance, we believe it is an important practical observation, since women often are the medical decision makers for their families. This information may be useful in planning the content and intensity of community consultation activities, to ensure that adequate time and effort is devoted to those groups with less support or understanding of these complex topics.
We also found that certain respondent characteristics were associated with the response of “no opinion” regarding research and consent concepts. This response could represent uncertainty, a lack of adequate information , or reluctance to state an opinion. Regardless, the characteristics of this group are key to community engagement in the research process. In almost all questions we asked, those who responded with “no opinion” were, or tended to be, those with lower incomes and less education. In many types of community consultation activities, such as the use of pre-existing meetings, individuals with no opinion might not be recognized. Analyzing only the responses of those who voice an opinion during community consultation activity might lead investigators and IRBs to a biased impression of the acceptability (or lack of acceptability) of the research within the entire community . Discerning why some persons have no opinion ( ie. they don’t understand the concept being described), might address the adequacy of the community consultation activity itself.
It is logistically impossible to consult with or even identify every member of the community in which an EFIC trial is to occur and from which study subjects will be drawn. In fact, the definition of community is itself not always clear to potential research subjects themselves. ( 4 ). Many types of consultation have been attempted, with various degrees of community involvement; many believe that community consultation may be one of the most difficult of the EFIC requirements to fulfill ( 8,9 ).When public meetings are held, attendance is often low ; Booth et al.,( 1 ) found that , while 65% of interviewed ED patients supported pubic meetings as a means of community consultation , fewer that 35% stated they would attend such meetings. Public meetings called specifically for community consultation on a proposed EFIC trial also are often poorly attended and may result in biased attendance not representative of the broader community ( 10 ). Focus groups provide the opportunity to discuss issues in more detail and more specifically, but may not reflect the feelings of the broader community ( 11 ). Recently, Dickert et. al ( 2) performed structured interviews of survivors of sudden cardiac death, in order to obtain the perspective of those most intimately involved with a condition that would qualify for EFIC research studies. While this unique approach is perhaps the most relevant to the question of EFIC, it is labor intensive, requires an available and cognitively intact survivor group, and may in fact be biased towards altruism and trust in the medical establishment that ,in fact , saved the lives of the participants.
We chose a survey technique for community consultation to obtain opinions ( and identify characteristics of those with favorable , unfavorable and no opinions) from a large representative group in a relatively short time frame. Surveys have been successfully used by others to gather pubic opinions about emergency medicine research and EFIC . ( 6,12, 13). Random digit dialing has been described as a means of community consultation , using scripts describing the proposed EFIC study and a survey to assess attitudes (14 ). Survey techniques can potentially reach a broad constituency , but may be subject to responder bias ( 15 ). In order to avoid this, we surveyed a large number of individuals but we acknowledge this possibility. If well -crafted, a survey can provide good insight into community attitudes in an anonymous and non - threatening manner. However, we believe that, in order to fulfill the requirement that community consultation be a two -way communication between investigators and the community, surveys must include the opportunity for respondents to state their concerns through open ended questions , coupled with the immediate availability of the investigators to answer questions and address concerns.
The responses obtained to a variety of questions suggest altruistic motives for participation in research. Very few of the respondents who had previously participated in research had done so for concrete benefits, while those who refused did so because it was not convenient to participate. Our respondents were willing to allow themselves to be enrolled in research trials with surrogate consent or with EFIC, even with no direct benefit, but with the potential to benefit others. Altruism has been noted as a motivation for participation and for support of emergency research in many other studies. Survivors of sudden cardiac death would participate in research because of its potential benefit for future patients.( 2). Blixen and Agich ( 16) found that a large majority ( 83%) of stroke patients were willing to be enrolled into research trials ( although half were uncertain about enrollment without informed consent): their motivations were primarily altruistic. Altrustic attitudes, even in the face of risky studies, imply a certain degree of trust towards the research and medical establishment. Most survivors of sudden death ,when interviewed about attitudes towards emergency research ,exhibited trust towards the clinicians , the medical community and the process of scientific review of a proposed research project( 2). The public trust is required for in acceptance of all research; with EFIC studies, it is especially important. Public confidence in the research enterprise can be strengthened with thoughtful approaches to community engagement ( 17,18).
Emergency research and the proposed EFIC trial is supported in the community in which the research will occur. The concept of EFIC is better supported when a specific trial is described and when respondents answer for themselves. Specific respondent characteristics are associated with attitudes or no opinions about EFIC and research; with this information, community consultation can be tailored to be more meaningful.
