Construct of decision making capacity

A 79-year-old male with coronary artery disease, hypertension, non-insulin-dependent mellitus, moderate dementia, and chronic renal insufficiency is admitted after a fall evaluation. He is widowed and lives in an assisted living facility. He’s accompanied by his niece, is alert, and oriented to person.

His labs are notable for potassium of 6. See full list on the-hospitalist. Hospitalists are familiar with the doctrine of informed consent—describing a disease, treatment options, associated risks and benefits, potential for complications, and alternatives, including no treatment. Not only must the patient be informe and the decision free from any coercion, but the patient also must have capacity to make the decision. Hospitalists often care for patients in whom decision-making capacity comes into question.

It is important to differentiate capacity from competency. Competency is a global assessment and a legal determination made by a judge in court. Capacity , on the other han is a functional assessment regarding a particular decision.

Capacity is not static, and it can be performed by any clinician familiar with the patient. A hospitalist often is well positioned to make a capacity determination given established rapport with the patient and familiarity with the details of the case. The Mini-Mental Status Examination (MMSE) is a bedside test of a patient’s cognitive function, with scores ranging from to 30.

Proxy decisions about participation are ethically complex, with a disparity between normative accounts and empirical evidence. Concerns about the accuracy of proxies’ decisions arise, in part, from the lack of an ethical framework which takes account of the complex and morally pluralistic. In the presence of cognitive impairment from any cause, determining whether a patient has adequate capacity is critical to striking the proper balance between respecting patient autonomy and.

What is decision making capacity? Is decision making capacity permanent? At what point does decision making that is affected by a neuropsychiatric disease process no longer represent “competent” decision making? These are some of the essential, and perplexing, questions of clinical capacity assessment. We use the term capacity to refer to a dichotomous (yes or no) judgment by a clinician or other professional as to whether an individual can perform a specific task (such as driving or living independently) or make a specific decision (such as consenting to health care or changing a will).

There are at least eight major capa. A conceptual model of consent capacity based on U. The first is expressing a choice, which is the ability simply to convey a relatively consistent treatment choice. The third is appreciation, which is the ability to relate diagnostic and treatment information and related consequences to on. Treatment consent capacity in older populations is the most extensively researched of any of the civil capacities, although the overall number of studies is still small. In our review of studies (some with multiple publications), patient sample sizes ranged from to 1individuals (M = 4 SD = 24), as presented in Table 2. Along with medical decision making and driving, financial capacity is a vital aspect of individual autonomy in our society.

Despite its importance, there have been few working conceptual models of financial capacity. One proposed model that combines cognitive neuropsychological and clinical aspects contains three elements. The first is declarative knowledge, which is the ability to describe facts, concepts, and events related to financial activities (knowledge of currency, concepts such as interest rate or loans, and personal financial data).

Empirical research in the area of financial capacity in older adults has only recently emerged. The second is procedural knowledge, which is the ability to carry out mo. Capacity assessment of older adults will become increasingly important over the coming century. The convergence of increased longevity, cognitive aging and dementia, blended families, and the intergenerational transfer of wealth in our individualistic society are making , and will continue to make, issues of capacity loss in older adults a prominent public policy concern.

The past years has witnessed the emergence of capacity assessment in aging as a field of study, with a growing body of empirical studies, a promising first generation of capacity assessment instruments, and a small but growing cadre of scientific researchers. Two clinical areas that have received the most research attention are treatment consent capacity and financial capacity. These studies await replication, but they provide a depart. The origins of our contemporary concept of decisional capacity liein a varied configuration of historical developments in health care lawand ethics that accompany the rise of the doctrine of informed consent.

Allowing adultpersons and some children to make their own health care decisions is anessential component of this conception of autonomy. Comprehensive theories of decisional capacity fall into two maingroups. Despite this variety of approaches, it is possible to identify someshared posits in leading contemporary work on decisional capacity.

Veryoften, decisional capacity is divided into four sub-capacities. Two central assumptions underlie virtually all contemporary work ondecisional capacity. These derive largely from the requirements thatthe law imposes on the ethics of informed consent. Thesignificance of this assumption is that capacity is always assessedrelative to a specific decision, at a particular time, in a particularcontext. As defined above, the term “decisional capacity” ismeant to capture a component of informed consent.

Yet while there is some agreement onwhat the sub-capacities that underlie decisional capacity are supposedto be, the same cannot be said of the term “decisionalcapacity” itself. In fact, there is a large amount ofdisagreement and confusion over whether “decisionalcapacity” is an appropriate term to refer to this element ofinformed consent. The other candidate is the term“competence. Generally, in these discussions,‘capacity’ and ‘competence’ areunderstood to mean ‘decisional capacity’ and ‘mentalcompetence’, respectively.

These terminological infelicities cancause considerable confusion but are often overlooked. One way to settle our problem is to use the terms“capacity” and “competence” interchange. A theory of decisional capacity must allow for the fact that healthcare subjects can make unpopular decisions, even ones that areconsidered highly irrational by others. The challenge is that, whilea theory of decisional capacity must allow for such apparentlyirrational decisions, it must also embody a clear and robust test ofcapacity. It is therefore an important desideratum of an adequatetheory of decisional capacity that it permit some kinds of highlyirrational decisions, but forbid others.

The most widely accepted solution to the requirement that atheory of decisional capacity permit some irrational decisions but. Part of what is involved in reasoning about a particular course ofaction and reaching a decision is weighing the risks and benefits andconsequences of proposed options. In health care contexts where consentis at issue, this normally amounts to a decisional problem that isframed in symmetrical terms: either one consents to a given treatmentoption, or one refuses that same treatment option.

This way of framingthings seems to assume that both poles of the decision are symmetricaland that mental capacity necessarily remains fixed as one evaluates thetwo options. Yet this is an assumption that can be philosophicallychallenged. It is sometimes argued that treatment decisions and refusals are notsymmetrical.

The reason is that the risks respectively associated withconsenting to or refusing treatment are not the same. In assessing claims about capacity, it is important to distinguishbetween descriptive and factual aspects of capacity on the one hanand prescriptive and normative aspects on the other. In this example, the first claim addresses theissue whether the individual is decisionally capable. Thesecond claim addresses the issue whether the individual shouldbeconsidered decisionally capable.

Note that this dual nature ofcapacity goes beyond individual judgments of capacity and extends totheories of capacity as a whole. It is especially important not toconflate or equivocate between these two aspects of capacity whenassessing theories and determinations of capacity. At the same time,paying heed to the d. Thus, in the initial instance, a theory is built around aselection of paradigm examples of what capacity and incapacityshouldbe taken to be.

We saw abovethat there are instances where the assessment of yielded byspecific tests for capacity start to merge into normative evaluativequestions that bear on the empirical validity of those tests. In fact,questions of empirical validity are a matter of increasing concern inthe recent literature on capac. The example of anorexia above shows that concerns about the empiricalvalidity of theories and tests of decisional capacity are not alwayssimply based on a clash of intuitions over paradigm cases.

A similar casecan be made for the centrality of values in conceptualizations ofvoluntarism, another pivotal ingredient of informed consent. Whichbrings us back to the topic of emotion and the status of value as anelement of capacity. Together with decision-making capacity and the provision of relevantinformation, the capacity for voluntary choice — voluntarism— is one of the three fundamental pillars of informedconsent. The Code goes on tospecify that, “the person involved…should be so situatedas to be able to exercise free power of choice, without theintervention of any element of force, frau deceit, duress,overreaching, or other ulterior form of constraint or coercion…” (ibid.).

This principle, which is meant toprotect the inviolability of the capacity for voluntary choice in thecontext of research, is also fundamental in the ethical and legalprinciples that govern the doctrine of informed consent in the contextof treatment. Until recently, there has been a remarkable paucity of empiricalresearch on the capacity for voluntary choice in the cont. It would be more pleasant, and your guests would be more comfortable.

Now we can return to the problems faced by the Stygian Chemical management. A decision tree characterizing the investment problem as outlined in the introduction is shown in Exhibit III. But let us go beyond a bare out. This is all that must be decided now.

We are now ready for the next step in the analysis—to compare the consequences of different courses of action. At Stygian Chemical, as at many corporations, managers h. Of course, the gains must be viewed with the risks. The time between successive decision stages on a decision tree may be substantial. At any stage, we may have to weigh differences in immediate cost or revenue against differences in value at the next stage.

Whatever standard of choice is applie we can put the two alternatives on a comparable basis if we discount the value assigned to the next stage by an appropriate percentage. The discount percentage is, in effect,. In illustrating the decision -tree concept, I have treated uncertainty alternatives as if they were discrete, well-defined possibilities. For my examples I have made use of uncertain situations depending basically on a single variable, such as the level of demand or the success or failure of a development project.

I have sought to avoid unnecessary complication while putting emphasis on the key interrelationships among the present decision , future choices, and the intervening uncertainties. Drucker has succinctly expressed the relation between present planning and future events: “Long-range planning does not deal with future decisions. It deals with the futurity of present decisions.

Today’s decision should be made in light of the anticipated effect it and the outcome of uncertain events will have on future values and decisions. The people who act as witnesses to the making of an enduring power of attorney need to certify or state that the person making the power of attorney appeared to have decision making capacity to make the power of attorney. A person is presumed to have decision making capacity unless there is evidence to the contrary.

Supported decision-making (SDM) allows individuals with disabilities to make choices about their own lives with support from a team of people they choose. Individuals with disabilities choose people they know and trust to be part of a support network to help with decision-making. Instead of having a guardian make a decision for the person with the disability, SDM allows the person with the disability to make his or her own decisions. People under guardianship do not have the right to make their own decisions about important matters.

A guardian makes choices for individuals about major life issues including personal health care , finances , whether to marry and raise a family , with whom to associate , and other day-to-day decisions. United States are under guardianship, but the number could be as high as million, given the remarkable dearth of data. See Restoration of Rights in Adult Guard. All adults, including individuals with disabilities, have will and preferences, and therefore have the right to make their own decisions, including life decisions about their health care, their finances, their relationships, where they work, where they travel, who they vote for, and where they live and with whom. The people they trust know their values, their goals, their will, and their prefe.

The individual chooses supporters he or she trusts. Individual and supporters execute a supported decision-making agreement. Supporters commit to honoring the individual’s decisions. An independent evaluation of our first demonstration project, involving nine people with disabilities aged to 8 found that SDM is an effective alternative to guardianship.

Instead of having other people make decisions about them on multiple issues, the pilot participants solicited information, conferred with their supporters, and then reached their own decisions. For example, one woman talked to her supporters about marriage, and whether or not to move in with her long-time boyfriend. See Kristin Booth Glen Supported Decision - Making and the Human Right of Legal Capacity. Decision - making can be regarded as a problem-solving activity yielding a solution deemed to be optimal, or at least satisfactory.

It is therefore a process which can be more or less rational or irrational and can be based on explicit or tacit knowledge and beliefs. The issue of capacity or decision making is a key one in safeguarding adults. It is useful for organisations to have an overview of the concept of capacity.

The MCA is about making sure that people over the age of have the support they need to make as many decisions as possible. In addition, DMC is decision -dependent, meaning that a patient might have sufficient DMC to make a relatively straightforward decision , but not enough to make a complex medical decision. Increasing age and cognitive impairment are associated with lack of decisional capacity. Surprisingly, however, psychiatric illness does not correlate with lack of decisional capacity. Other studies have shown that patients with schizophrenia are more likely to lack decision - making capacity that those with depression.

Decision making and problem solving are ongoing processes of evaluating situations or problems, considering alternatives, making choices, and following them up with the necessary actions. Sometimes the decision - making process es extremely short, and mental reflection is essentially instantaneous.
