Informed consent for clinical treatment

CMAJ March twenty, 2012 184 (5) 533-540; DOI: https://doi.org/ten.1503/cmaj.112120

Although informed consent for clinical treatment has become a vital part of contemporary medical practice, information technology ways different things in different contexts (Effigy ane), is variably practised and rarely achieves the theoretical ideal. In this review, we focus on the clinical practice of informed consent. We first depict what we know about informed consent: what information technology is, where information technology came from and what purposes information technology serves. Nosotros then describe several limitations that complicate the do of informed consent. Finally, we make several practical suggestions as to how clinicians might optimally approach the informed consent process.

A summary of the bear witness used in this review is available in Box 1.1 Although we had hoped to identify high-quality studies that would provide a strong quantitative base of evidence for recommendations around informed consent, much of the quantitative literature on this topic is descriptive in nature. Informed consent is primarily a legal and ethical concept; although frequently informed past information, the standards of scholarship in law and ethics focus on the strength of analytical argument rather than the weight of empirical data. Therefore, nosotros sought to synthesize the available knowledge on this subject, referencing empirical data when possible, summarizing relevant arguments that are particularly prevalent, persuasive or insightful.

Show used in this review

This review is based on a wide Medline search for articles pertaining to informed consent in clinical settings, with a focus on surgery. The bibliography was expanded by adding related books and manufactures developed from reference lists, personal contacts, conference proceedings, and the coauthors' bibliographies. Focused Medline searches regarding specific aspects of informed consent were done as needed to address whatever gaps in our existing knowledge. The resulting bibliography reflects a bias within the literature toward surgery and other procedural disciplines such as gastroenterology, radiation oncology or interventional radiology. Nevertheless, the findings in these areas are transferable to other fields of medicine in which physicians must seek their patients' consent for proposed treatment.

The recent systematic review past Schenker and coworkers,ane in add-on to our update of their search, found few "level 1" studies. We noted that much of the literature on the topic of informed consent is descriptive and that in that location are a wide range of interventions and outcomes tested by the identified randomized comparisons. Our bibliography includes randomized controlled trials, meta-analyses, systematic reviews, qualitative descriptions of patient and doc experience, and observational studies by sociologists and psychologists, in addition to books and articles that examine the law, ethics and policy of informed consent.

What is the purpose of informed consent?

Informed consent has go the main paradigm for protecting the legal rights of patients and guiding the ethical practise of medicine. It may exist used for different purposes in different contexts: legal, upstanding or administrative (Figure ane). Although these purposes overlap, they are not identical, thus leading to dissimilar standards and criteria for what constitutes "adequate" informed consent.

Legal

Although the concept of consent is rooted in ancient legal and philosophical precepts, the modern legal precedent for "simple" consent was written in 1914, establishing a patient's "correct to determine what shall be done with his body."two The farther obligation for physicians to disclose details about treatment in a process of informed consent did not sally until the 1950s,3 when courts kickoff required physicians to disembalm information customarily disclosed by experienced clinicians (due east.m., the reasonable physician standard). It was non until 1975 that American courts articulated the reasonable person standard, which required that physicians disclose the information that a "reasonable person" would desire to know in a like situation.iv Regardless of the standard used, informed consent is further predicated on the patient's or surrogate'south capacity to brand decisions — non merely should the decision-maker understand the relevant information, he or she should also be able to appreciate the information's importance and employ it to weigh treatment options in light of their values.5

Legally, simple consent protects patients against assail and battery in the form of unwanted medical interventions. The higher standard of informed consent further safeguards patients' rights to autonomy, cocky-conclusion and inviolability. All the same, the legal standards that apply to obtaining informed consent vary across jurisdictions, and their interpretation continues to evolve. Some jurisdictions apply the reasonable person standard, whereas others continue to use the older standard of the reasonable physician. Therefore, information technology is important for clinicians to determine the precise standard used in their jurisdiction and to arrange their practice accordingly. The Canadian Medical Protective Clan provides detailed data on Canadian standards (www.cmpa-acpm.ca). Even when the standard is clear, interpretation is required to utilise the standard to a item case; thus, near litigation regarding informed consent focuses on precisely what information satisfies the applicable standard.6 Fortunately, in well-nigh cases, legal estimation is businesslike; bear witness of a proficient-organized religion try to inform is usually plant to be adequate.

Ethical

The ethical purpose of informed consent is somewhat more than abstract and ideological, seeking to respect patient autonomy by ensuring that treatment is directed toward the ends desired and is called past the patient. In this context, informed consent is intended to shift the ethical paradigm for decision-making away from doc-centred models to more patient-centred approaches. The ethics literature regarding informed consent as well emphasizes that it is not an issue, but a procedure that precedes the "signing" of the certificate and continues for as long as the choice remains relevant. Thus, the consent to undergo dialysis or go along with chemotherapy is continually re-evaluated (and may alter). The consent form should not be confused with the consent process; the class merely documents that the process has occurred. Importantly, other parts of the patient record (e.g., clinic and/or operative notes) should corroborate details of the process.

Authoritative

For the sake of compliance, the informed consent document serves the administrative purpose of a systems-level check to ensure that a consent process has occurred. Patients simply do not advance to the operating room, for example, without a signed consent grade. Unfortunately, pressures for efficient workflow may shift the focus of the informed consent process from robust chat to the mere requirement of getting a signature.

Although legal and ethical debate persists, most stakeholders in the informed consent process concur on at least four basic elements for discussions of informed consent: the conclusion-maker (i.eastward., the patient or a surrogate) should take the capacity to make decisions; the physician should disclose sufficient details for the decision-maker to make an informed choice; the decision-maker should bear witness his or her understanding of the disclosed data; and the conclusion-maker should freely authorize the handling plan.

In current clinical exercise, these four elements interpret into five components that should exist included in a discussion seeking to obtain informed consent: the diagnosis, the proposed treatment, the bellboy risks and benefits of the handling, alternative treatments and their risks and benefits, and the risks and benefits of declining treatment.7

What factors affect obtaining informed consent?

The practice of informed consent is complicated by several well-documented limitations. These constraints include patient comprehension, patient use of disclosed information, patient autonomy, the demands placed on wellness intendance providers and how well physicians meet the minimal standards for disclosure.

Patient comprehension

Data repeatedly show that patients remember fiddling of the information disclosed during the informed consent process8^–11 and that their level of comprehension is frequently overestimated.12^,thirteen Comprehension is related to factors such every bit patient historic period,10^,14 education,ix^,14^,15 intelligence,10 cognitive role,ten locus of control10 and feet.9 Not surprisingly, the measure besides relates to the instrument used to appraise comprehension,sixteen^–xviii as well as to the topics covered by the questions asked.14^,16^–18 Furthermore, patient comprehension and think deteriorate as fourth dimension between consent and testing of the patient's understanding increases.9^,10^,xvi^,17

Patients' use of disclosed information

The theory backside informed consent presumes that patients will employ the data disclosed in autonomous and rational means. Unfortunately, this presumption is not always fulfilled in exercise. Although patients are uniformly interested in learning most proposed surgical procedures,19^–22 the detail desired varies from patient to patient.19^,21^–26 Some patients' preferences for information focus less on decision-making and more on setting realistic expectations for their upcoming surgery.27^–29 Furthermore, although some patients make decisions in a linear, rational way, considering specific risks and benefits, other patients base their decisions on intuition or instinct ("I don't care what yous tell me, Doc, the cancer has to come out").29^–33 Still others may base their decisions on something other than risks and benefits (eastward.g., the hospital's reputation or patients' subjective assessments of surgeons' commitment to "care" for them).34^,35

Even when patients practice deliberate over their decisions, the social forces inherent to the health care system can undermine the effectiveness of informed consent. In a qualitative study involving women consenting to gynecological procedures, several patients described feeling compelled to sign the consent form despite their firm preference not to practise so.36^,37 This finding is supported past related survey information showing that thirty% of women (220/732) consenting to surgery did not think they had a choice nearly signing the consent form,38 and that well-nigh of the women (88% [642/732]) perceived the grade as "just another piece of paper" that satisfied administrative and legal requirements.39

Patient autonomy

Some other assumption of informed consent is that patients exercise their autonomy independently. Even so, qualitative and quantitative data from Canada and the Usa suggest that many patients prefer to delegate or defer their decisions to others,40^,41 or that they prefer to make decisions collaboratively within their support systems.42^,43 For instance, Degner and coauthors plant that 57%–59% of patients with cancer from sample populations in Manitoba consistently preferred to delegate all or some of their medical decisions to other people.twoscore^,41 Furthermore, when patients were asked what was nigh important about the informed consent process, their responses focused less on controlling and more on building the trust needed to allow them to brand a "jump of faith" to a surgeon's care.34^,35 For this reason, critics contend that rather than protecting patients' rights to make decisions as they see fit, informed consent paradoxically mandates that patients brand decisions and do autonomy in a manner that may be contrary to their preferences and foreign to their experiences.29^,44

Demands on providers

A rigorous informed consent process is difficult and takes fourth dimension from busy clinical schedules. Such time commitments are rarely recognized or rewarded by health care administrators. A recent study measured the fourth dimension required for providers to obtain informed consent for elective surgery when using an electronic form.45 In that study, the mean time taken by the provider was ten.9 minutes, with a large standard difference (22 min).45 Studies involving orthopedic and vascular surgeons showed similar results — the average fourth dimension needed to obtain consent for orthopedic procedures was 16.ane (range iii–76) minutes;46 the average was 12.1 (range five–20)47 minutes for a carotid endarterectomy. These measurements very likely underestimate the true time commitment involved, because they only included the time spent discussing the class. Additional fourth dimension required for whatever discussions that the patient may have had with his or her primary intendance provider before the surgical referral, or with the nurses, midlevel providers or the surgeon in the surgical outpatient surface area before completing the formal documentation, was non included.

Informed consent also demands maturity and self-awareness on the provider's part to resist the temptation to carelessness (or subconsciously subvert) the difficult task of shared decision-making.48 For example, a study involving urologists and radiations oncologists showed the unconscious bias of each discipline to its own mode of treatment for a hypothetical case of localized prostate cancer, even though the evidence favoured watchful waiting.49 Vigilance is required to manage the subtle means clinicians favour some treatments over others. However, it is impossible to remove all bias. Physicians must use their clinical experience to make specific recommendations while ensuring that the grounds for these recommendations are as transparent equally possible. In the stop, shared decision-making ultimately depends on the clinician's power to discern the degree to which patients can and want to be involved. Although informed consent procedures tin can assist in this process, they ultimately depend on prudent clinical judgment.

Physicians meeting minimal standards

Research suggests that physicians rarely meet even minimal standards of disclosure for the purposes of obtaining informed consent.50^–54 For case, Braddock and colleagues51 looked at 1057 physician–patient encounters involving 59 primary care physicians and 65 general or orthopedic surgeons. Only 9% of the 2553 clinical decisions made during these encounters met the criteria for completely informed decision-making.

Despite the consensus that informed consent should pervade medical practice, the prove shows that physicians and patients rarely reach the theoretical platonic. Indeed, qualitative research suggests that patients and physicians view the consent process primarily as a tool for building trust rather than as a technique for decision-making.34^,35 Withal, a discussion with the goal of building trust would not necessarily expect the aforementioned as a discussion with the goal of controlling.

How tin can obtaining informed consent exist improved?

The law and ethics of informed consent both reflect and enforce the movement from physician-centred to patient-centred determination-making. Nonetheless, there is increasing recognition that the pendulum may have swung as well far, such that some approaches to informed consent go beyond respecting patients' cocky-decision to mandating that they do their autonomy in a very particular style.29

To accost this concern, there is a growing focus on a shared process of decision-making — a process that emphasizes the disquisitional importance of patient input while recognizing that it should be tailored to each patient'due south power for and interest in participation, and that the physician'south contribution to the conclusion is important and deserving of its own respect.55 To the extent that medical treatment is a partnership betwixt patient and clinician, the moral responsibleness for decisions is carried past both partners. Neither partner should dominate the determination, nor should either partner be disenfranchised from their prerogative and privilege to participate equally a moral agent in the determination. Back up for this paradigm shift was recently articulated past an international consensus panel in the "Salzburg statement on shared decision making" (Appendix 1, available at www.cmaj.ca/lookup/suppl/doi:ten.1503/cmaj.112120/-/DC1.), which calls on clinicians, patients and policy-makers to change their practices, expectations and laws to more than thoroughly share the responsibility for decision-making between clinician and patient.56

Another approach argues that informed consent pertains primarily to those decisions that involve choices well-nigh the goals of medical handling. Although this approach has not been tested empirically, Joffe and Truog57 suggest that overly rigid interpretations of informed consent confuse and conflate two split up roles of physicians. Joffe and Truog assert the importance of eliciting patients' values, primarily to permit the physician and patient to reach agreement nigh the goals of medical intendance. Having agreed on the goals of care, the physician, equally the patient's fiduciary agent, is then free to make decisions about the technical ways by which these goals are most effectively achieved.57 In our ain practice, establishing a clear consensus regarding the intended goals of treatment is certainly one of the most important steps in the informed consent process.

How can informed consent be implemented in exercise?

A thorough practice of informed consent is circuitous, requiring flexibility to address its multiple goals. These goals include the legal goal of protecting patients' rights, the ethical goal of supporting democratic decision-making, the administrative goal of providing efficient health care and the interpersonal goal of building the trust needed to proceed with therapeutic interventions. The responsibility of clinicians is even greater given the substantial limitations to informed consent. As noted previously, in that location is little high-quality (i.e., level 1) prove to guide do. For this reason, nosotros offer the post-obit comments to support physicians' attempts to meet the ethical and legal ideals of informed consent. Our suggestions are grounded in the interdisciplinary literature reviewed here, as well equally in our own clinical experience practising general surgery and internal medicine.

Involve patients in decision-making

The best way to come across the legal requirements of informed consent is to develop a consequent practice of involving patients in decisions, fifty-fifty if that interest may occasionally be limited (Box 2).1^,half-dozen^,45^,58^–61 Equally with any aspect of medical practice, a systematic approach is important. Clinicians can develop a system to ensure that the discussion is not limited to the disclosure of risks, simply also includes relevant details about the expected benefits, possible alternatives, and what to conceptualize before and afterwards the procedure. Furthermore, clinicians can ensure that the patient or surrogate has the chapters to brand decisions, and that the choice is beingness made voluntarily without undue influence.

Box 2:

Suggestions for optimizing clinical informed consent1^,6^,45^,58^–61

• Develop a practice of involving patients in decisions. This practice should be:

  • - sensitive to patients' preferences for information and their decision-making styles

  • - consistently practical to all patients

  • - designed to systematically address not only the risks of care, but also the expected benefits, relevant alternatives and what to anticipate earlier and after the procedure

  • - designed to ensure:

    • - the decision-making capacity of the patient or surrogate

    • - a voluntary choice free of undue influence

    • - comprehension (e.m., ask patients to repeat what they heard)

• Explicitly found the goals of care, and prioritize them in the context of the patient's other life goals.

  • - Commonly understood goals of care may require fiddling clarification.

  • - More explicit give-and-take will be needed as decisions become more than complex.

• Recognize that the informed consent procedure serves more one purpose. Allow the process sufficient flexibility to fulfill its varied purposes:

  • - legal purpose to protect patient rights

  • - ethical purpose to support autonomous self-determination and decision-making

  • - administrative compliance to promote efficiency in health care

  • - interpersonal purpose to build the trust necessary to go on with therapeutic intervention

• Document the process thoroughly, using an electronic medical tape whenever possible to ensure permanence. This may require more than than one arroyo depending on your local legal, ethical and compliance standards. Techniques may include:

  • - process-specific consent forms

  • - patient pedagogy materials (written and electronic)

  • - narrative notes describing the informed consent process and the goals of care

  • - decision aids for particularly complex decisions (e.g., treatments for breast cancer)

Failure to obtain informed consent can pb to legal activity. That said, prosecution is rarely successful when there is show that the clinician has fabricated a skillful-faith effort to inform the patient. Furthermore, given that the risk of litigation often depends on patient dissatisfaction due to lack of advice or rapport with the physician,62 strong practices for informed consent may actually prevent such suits from existence filed. Preliminary evidence suggests that master intendance physicians who routinely bank check their patients' understanding as part of the informed consent process are at reduced take a chance for law suits.63

Encourage and cheque patient comprehension

Strategies for improving patients' comprehension of the relevant risks, benefits and alternatives include decision-making worksheets,64 standardized and more readable consent forms,23^,65^,66 educational curricula,55^,67^,68 multimedia decision aids,69^,70 extended discussions71^–74 and test/feedback techniques.45^,58^,75 Although the Cochrane database identifies more than 200 decision aids and reviews 34 randomized controlled trials designed to improve patient comprehension, the results are mixed.59 A recent systematic review1 identified 44 intervention trials designed to ameliorate patient comprehension during informed consent. Although these interventions generally succeeded in this goal, they focused primarily on procedure-related risks, neglecting relevant alternatives, benefits or general knowledge about the procedure. Simply 6 of the 44 trials assessed all four elements of patient comprehension.

Preliminary efforts have been made to incorporate patient-specific take a chance calculators into procedure-specific consent forms.76^,77 It is unclear whether such instruments will change patient decisions or experiences. Although the development of such tools requires a substantial investment of time, often across the reach of many physicians, the elementary exercise of asking patients to repeat what they heard the clinician say can aid evaluate a patients' understanding; this do has improved patient comprehension in several studies.45^,58^,75

Establish goals of care

It is critically important to plant the goals of care and prioritize them in the context of the patient's other life goals. For common procedures, this may require little clarification, but more explicit discussion will be needed as decisions become more complex. Indeed, effective communication about goals does not necessarily come naturally; some clinicians are better at the informed consent process than others. Whenever possible, one should have the opportunity to notice and learn from principal clinicians as they engage patients in discussions concerning informed consent.

No handling is gratis of adventure. Given patients' expectations, it is essential for physicians to emphasize the uncertainty inherent to all medical interventions. Much of the consent process should be directed at establishing reasonable expectations for a handling'southward event. The language of medicine may impede this goal when terms such as "knee replacement" or "oncological response" seem to hope something more perfect than physicians intend.

Certificate the procedure

Clinicians should certificate the content of these discussions to provide evidence of their good-faith efforts. However, given the diversity of purposes served by the informed consent process, appropriate documentation may require more than i technique. The standardized form all-time suited for documenting authoritative compliance may not be ideally suited for documenting the goals of care or the type of word that builds trust. Thus, it may be necessary to employ multiple diverse tools to support and document a robust informed consent process.

For particularly complex decisions (e.g., managing breast cancer), Sepucha and colleagues accept developed determination aids that seek to ascertain the hierarchy of values each patient considers relevant to a specific decision.lx^,61 Having determined and prioritized those values, the decision aid can aid patients in choosing the therapeutic course (e.g., breast conservation five. prophylactic bilateral mastectomy) that well-nigh probable achieves the patient'southward stated values (e.one thousand., minimally invasive therapy with improved cosmesis 5. maximal risk reduction).lx^,61 Like approaches have been developed for benign prostatic hypertrophy,78 and work is in progress to create such tools for joint replacement and middle disease.61 Although such an arroyo is not particularly efficient for meeting the legal and bureaucratic imperatives of informed consent, it is 1 of the best tools for supporting the ethical ideal of informed consent. However, the investment required to develop these tools may non be warranted for less complex decisions such as excising melanoma or repairing inguinal hernias.

I style to clearly document the informed consent discussion is to develop written materials that contain information relevant to the specific procedure. This documentation could accept the form of booklets, pamphlets or procedure-specific consent forms, many of which take been developed past private clinicians, practices and hospitals. Such resource are peradventure best suited for fulfilling the authoritative and legal requirements of informed consent.

At that place are commercially available products that tin back up clinicians and patients in the informed consent process. These may provide procedure-specific consent forms and educational materials for patients for medical and surgical specialties, or support their generation locally. Increasingly, Web- or computer-based resources are available, which may be printed or uploaded to an electronic medical record.

Two recent studies have shown that a figurer-based consent tool improved patients' comprehension of procedure-specific risks, benefits and alternatives from l% to 60%,72 with a dose–response suggesting that comprehension improves as more fourth dimension (up to 15 min) is spent with the resource.58 Another tool, which is accessed online, improved patient satisfaction and self-rated comprehension for gastric featherbed, total knee arthroscopy and colonoscopy.76 When compared with written consent forms, the online tool objectively improved patient comprehension of procedure-specific risk, benefits and alternatives for diagnostic esophagogastroscopy.77 However, as with other enhancements, only 33% of participants using this tool achieved "adequate" informed consent as defined by researchers, reinforcing ongoing uncertainty about the criteria available for assessing the adequacy of informed consent.

Audiovisual and multimedia resources that teach patients almost specific procedures or decisions offer another approach for enhancing informed consent. Although such tools can provide substantive bear witness of the endeavor to inform patients, their focus is often less on documentation than on patient instruction. A review by Schenker and coworkers describes 15 audiovisual tools, of which 11 improved patient comprehension.1 Unfortunately, substantial investments of time and money were required to develop these tools.

Conclusion

Having emerged from multiple disciplines, inquiry concerning informed consent does non beget sufficient clarity or consensus regarding the purposes this process serves or the standards by which it should exist judged. Our businesslike suggestions aim to facilitate — and document — a skilful-faith try to involve patients in medical decisions to whatever degree they are interested and able. Such practice complies with the ethical spirit of informed consent and should minimize legal conflict past fostering a deep and nuanced respect for patients.

Cardinal points

• Informed consent means different things in different contexts, is variably practised and rarely achieves the theoretical ideal.

• Simple consent entails that a patient (or surrogate) with decision-making capacity freely authorizes a treatment programme aimed at a mutually best-selling treatment goal.

• The authorization is "informed" when the doc discloses and the patient understands the diagnosis, the relevant options for handling (including no treatment) and any corresponding risks and benefits.

• The informed consent process should be documented thoroughly, using an electronic medical record, process-specific consent forms, patient educational activity materials and other options whenever possible.
