Every day thousands of doctors help patients with decisions about medical interventions. A voluminous literature reflecting the views of philosophers, bioethicists, and legal scholars provides expert advice. Physicians learn from the literature that they are expected to help patients make "an autonomous authorization . . . of a medical intervention . . ."
1 and to "inform their patients about the nature of their condition and its expected course, about the benefits and risks of the proposed treatment, and of alternative treatment or nontreatment."
2 The emphasis on autonomy is accompanied by clear warnings against physician paternalism. Some scholars have questioned the doctrine of informed consent,
3,4 recognizing problems with the complexity of medical information,
5 the patients confusion and vulnerability when he or she is ill,
6,7 ambiguity and inconsistency among legal interpretations,
8 and lack of physician compliance.
3,8 Legal and institutional policy requirements emphasize disclosure of risk and prognosis to prevent lawsuits. Patients may wish to leave worrying about these troublesome matters to the physician.
7 Practitioners are caught in the middle of this unresolved issue.
The purpose of our study was to learn what patients believe about consent and decision making on the basis of their own experience. We asked postoperative patients to tell us about the values and beliefs that guided their decision making about a serious issue: surgical resection of esophageal cancer. What we found was unexpected. The patients told us that they did not experience shared decision making or informed consent as experts understand these processes. This is the patients story, as told by them, interpreted by us, then taken back to the patients for confirmation. We present it here to encourage further discussion and clarification of the consent process for treatment of life-threatening illness.

Design
Interviews with patients yielded data that we analyzed and developed into a conceptual model. This process, called "grounded theory" by sociologists, is "a general methodology for developing theory that is grounded in data systematically gathered and analyzed." It is appropriately used for data that are conceptually dense and involve social processes.
9,10 Written informed consent was obtained from participants. The study was approved by the research ethics committees of the participating institutions.
Data collection
We conducted face-to-face semi-structured interviews with each participant. A spouse or family member was often present during the interview; their comments were welcomed as part of the data. The interviewer asked open-ended questions, followed up participants responses, pursued themes as they arose, and sought clarification as required. The interview guide was developed with a pilot group of patients. Participants were asked what they thought and felt about their experience with decision making regarding their esophagectomy. As is common practice in qualitative research, the interview guide was modified to follow up issues emerging from the data as the study progressed. Copies of the guide are available from us on request. The interviews were audiotaped, transcribed, rendered anonymous, and kept in secure storage.
Data analysis
The analytic method, called "constant comparisons," was characterized by 3 steps: open, axial, and selective coding. During open coding, the transcripts were read and segments of text that related to a theme or idea were identified and given a conceptual label (eg, surgeon characteristics). During axial coding, similar concepts were grouped into conceptual categories that were developed further through comparisons between categories and between transcripts (eg, idealized surgeon). During selective coding, one core category emerged as the central theme of the study (entrustment), and conceptual relationships with other categories were developed. As is customary in qualitative research, data analysis began after the first interview and continued after all interviews were completed. The analysis was aided by reformatting with The Ethnograph computer software.

We used several techniques to verify the trustworthiness of our findings. During each interview, we summarized for participants what we thought they were saying to ensure that we clearly understood their meaning as well as their words. The primary analysis of the transcripts, conducted by D.K.M., was subjected to frequent critical discussion by both of us. At the end of the study, we conducted a group meeting with 5 study patients to clarify our comparisons between their experience and the models of consent and decision making in the literature and to confirm our choice of quotes to illustrate the patient perspectives. Patients agreement was required to include each element in the model. On 4 occasions we presented sections of transcripts and their interpretations to an interdisciplinary group of scholars in law, philosophy, bioethics, medicine, nursing, and social science, who are members of the Consent Research Network of the University of Torontos Joint Centre for Bioethics. Their comments were used to refine our interpretations.

Entrustment emerged as the core concept uniting the narratives of all our patients. Trust developed as the patients progressed from an initial state of profound vulnerability and distress to a feeling of confidence that the surgeon would make good decisions on their behalf and care for them with a high level of competence and fidelity to their trust. The conceptual model of entrustment that we developed from patients descriptions of their experience contains 6 elements, illustrated here by verbatim quotes from patient interviews:
Cultural belief in surgical cure
Nearly all of the patients in our study came to their surgeon with a pre-established belief that surgery is required for cure ("Its cancer; it has to be cut out." ). Support for this belief consisted of anecdotes from friends or family members with cancer in whom nonsurgical treatment seemed to destroy the quality of their residual lives, leading to a degrading death. In contrast, the patients knew of others who were alive and well after surgical treatment.We asked: "Can you remember what made you think that you had to have surgery?" Patient: Oh, it was the diagnosis of . . . a malignancy. The faster you get at that the better. In my case thats the way it turned out.
Enhancement of trust through the referral process
Patients described a series of visits to various physicians for tests and advice. Typically, symptoms led them to seek help from their family physician, who indicated that something was seriously wrong and referred them to a local specialist, usually a gastroenterologist or a general surgeon. After a number of tests the local specialist diagnosed esophageal cancer, indicated that a difficult and complicated surgical operation might be necessary, and recommended referral to a specialist surgeon at a university teaching hospital. Patients recalled that presentation of the opportunity for them to choose among alternative treatments undermined their confidence that their doctors "knew what they were doing." The stepwise process of referral reinforced the patients conviction that the problem was very serious and raised their expectations that the next physician at each stage could provide a higher level of skilled help. Our patients experienced at least two referrals before seeing their specialist surgeon. According to the patients, the referring physician recommended the specialist surgeon highly. Patients came to understand that their specialist surgeon embodied the highest available level of skill and expertise.[The local surgeon] said, "This is a malignancy, were sure of that. It requires surgery and its something I dont really think I should do in [local hospital]. I think you should go to [big city] for it." When I got down here, the first nurse I spoke to said, "You got the best one [surgeon]."
Idealization of the specialist surgeon
All of the patients recounted forming deeply respectful conceptions of their surgeons character and competence early in the relationship, despite a relatively short period of interpersonal contact. Patients idealized the surgeon, emphasizing positive attributes and minimizing shortcomings.P: Hes very fast, very good. Hes always there. Q: What made you think he was very good? P: Oh, his manner. (What about his manner?) Hes excellent. Hes always there. He makes you think that hes only there for you, while at the same time, you know damn well that hes got a stopwatch in his hand. He . . . make(s) the patient feel very good that way.
Belief in expertise rather than medical information
Patients considered themselves unqualified to process the diagnostic and prognostic information presented to them. Regardless of their level of education or career success, they felt incapable of making suggestions or decisions about their care because they lacked expertise and felt psychologically debilitated by anxiety and fear.I did not have a clue what they were talking about. It would not have made any difference to me. He knows what he is doing; let him go ahead and do it . . . . I cant say "No, I dont think you should do it that way."
As patients proceeded through the referral process to their specialist surgeon, their anxiety and sense of responsibility for making frightening decisions diminished, replaced by trust in the expert consultant.
Resignation to risks of treatment
Patients expressed the view that analyzing risks was irrelevant to their decision. They had to accept the risk and burdens of surgical treatment to escape a miserable death.I knew that the percentage survival varied between 10% and 50% . . . . It was . . . a moot point in the sense that not to get surgery would mean that you would proceed to the level where the odds are 0%. So did I agonize? There was no agonization . . . either you go forward or you fall down . . . to do nothing was to die.
Acceptance of an expert recommendation as consent to treatment
Patients did not perceive themselves to be making an informed decision; they viewed themselves as accepting an expert recommendation. They acknowledged two possible courses: (1) refuse surgical treatment, deteriorate, suffer, and die, or (2) accept surgical treatment. Since the first option was unthinkable, their only question was whether they met the qualifications for an operation.
The patients described themselves as relieved, encouraged, and hopeful when the surgeon recommended an operation. They felt "in control" of the decision process based on trust rather than information.P: I didnt know what to do. I just had to go along . . . . Q: Did you feel out of control? P: No. Never. Wife: He basically trusted what they said. (To P) Didnt you? P: Yes, everything they said. You have to . . . whats the sense of going through it if youre going to be worried? I wasnt worried in the least when I went through the operation.

Gastroenterologist and New England Journal of Medicine editor Franz Ingelfinger eloquently described a personal experience that reflects the same feelings our patients recalled. Ingelfinger reported how "confused and emotionally distraught" he and his multiphysician family felt when they were expected to make decisions about his own esophageal cancer.Finally, when the pangs of indecision had become nearly intolerable, one wise physician friend said, "What you need is a doctor." He was telling me to forget the information I already had and the information I was receiving from many quarters, and to seek instead a person who would dominate, who would tell me what to do, who would in a paternalistic manner assume responsibility for my care. When that excellent advice was followed, my family and I sensed immediate and immense relief.*
Our study extends and deepens the discourse opened by earlier empirical research into patients views about decision making and consent. The experience of entrustment that our patients described helps explain why Robinsons cardiac surgical patients "yielded . . . decision making to experts,"
19 ignoring or forgetting
20 his audiotaped preoperative discussions about risk. In questionnaire-based studies that used hypothetical illnesses of varying severity to assess decision making, the majority of patients thought they would delegate decision making to their doctors; more serious hypothetical illness prompted greater delegation.
21-23 A study of relatively asymptomatic outpatients in hypertension clinics using structured questions and Likert scale responses found that these patients defer to their physicians for most decisions, especially about initial treatment, but may prefer a more active role after having experience with the medication.
24 Our study subjects were more seriously ill and our questions open-ended; ideas and feelings such as idealization and entrustment emerged that are outside the scope of conventional questionnaires and scales.
Using qualitative methodology to evaluate patients views about decision making, Lidz and associates
25 interviewed and observed surgical and cardiology patients in a university hospital. They concluded that the legal model of informed consent failed "to deal with the realities of medical decision making." Barriers to incorporating the legal model into practice included the extended time course of decision-making processes and the tendency to disclose risks after the patient is emotionally committed to treatment. Rather than test a pre-established model, we used the qualitative analytic approach to develop an explanatory description of the patients experience. The resulting entrustment model may help reconcile legal theory and medical practice in a patient-centered direction.
The legal model of consent
5,16 places heavy emphasis on disclosure of risk. For the patients in our study, entrustment was the meaningful process; they signed the consent form to satisfy requirements of the hospitals in which they received their care. The standard bioethics model defines informed consent as "the autonomous authorization of a procedure by an individual patient" and views enabling and protecting individual autonomous choice as "the benchmark of moral adequacy."
1 But the reasonable, autonomous persons envisioned in the cool analytic atmosphere of an ethics seminar or judges chamber are not the vulnerable "sick human beings" we encountered, whose feelings are well described in Sherlocks insightful analysis of "the case of Mrs. B."
7 Our patients delegated responsibility for assessing medical information and making treatment decisions to their physicians and surgeons. This exercise of "second order autonomy,"
26 that is, making an autonomous choice to delegate decision-making authority to a collective such as ones church or military organization, may logically be applied to the physician-patient relationship.
26,27
Katz
28 argues that the legal doctrine of informed consent "was not designed as a medical blueprint for interactions between doctors and patients" but was intended as a prod to physicians to fashion a "doctrine that is responsive to the realities of medical practice." Katz recommends that physicians "attend to the task of giving meaning to the requirement of informed consent . . . because it is they who work in the trenches." Our data suggest that the perspectives of sick patients should be included in thoughtful reconsideration of informed consent for serious illnesses like esophageal cancer. As we attend to the task of developing a responsive and realistic approach to informed consent, we can be guided by the viewpoint and needs of those in the trenches with us: patients who are anxiously entering treatment. This is the viewpoint encountered daily by physicians and surgeons, as they work in the gap between legal theory and their clinical estimate of the patients needs and avidity for medical information.
Limitations
A limitation of this study is that the findings describe the experience of patients who elected to accept major surgery for life-threatening disease; our study participants may have felt more vulnerable, passive, and restricted in their choices than other patients. In general, the selection bias introduced by interviewing patients who have survived treatment and chosen to participate in a study can distort assessment of the decision-making process, especially if treatment failures are excluded.
29 However, our sample includes several patients whose treatment was not successful. Some knew their esophagectomies were palliative because unresectable metastases were found at the time of the operation. Some had recurrent cancer causing severe symptoms at the time of their interview. Remarkably, all of these patients reaffirmed the entrustment model, irrespective of the outcome of treatment. Patients with esophageal cancer who did not follow the pathway to surgery and patients with less-threatening disease may hold different views.
In summary, we developed a conceptual model of entrustment from the perspective of patients undergoing surgical treatment for esophageal cancer that captures their experience with decision making and consent. The model contains 6 elements: (1) cultural belief in surgical cure; (2) enhancement of trust through the referral process; (3) idealization of the specialist surgeon; (4) belief in expertise rather than medical information; (5) resignation to risks of treatment; and (6) acceptance of an expert recommendation as consent to treatment. Our model of entrustment should not be construed as subversive to the moral and legal requirement for communication between physicians and patients about the risks of failure, disappointment, or harm from treatment. The need for this respectful conversation
3 remains undiminished by our findings. Further development of legal, ethical, and policy frameworks for decision making and consent should include reflective analysis of patients experience. An effective response to Katzs challenge requires articulation and further analysis of the viewpoint of physicians and surgeons, as well as exploration of the patients perspective in a wider range of illnesses and treatments.
