Decision-making capacity in older medical in-patients: frequency of assessment and rates of incapacity by decision-type and underlying brain/mind impairment

BACKGROUND

Hospital clinicians find mental capacity assessment challenging and may lack the necessary skills. Given high rates of cognitive impairment, data on mental capacity assessment in real-world hospital cohorts are required to inform the need for staff training and workforce planning.

OBJECTIVES

In unselected medical inpatients, we determined the rate and outcome of mental capacity assessment by decision type and underlying brain/mind disorder, and recorded the discipline of the assessor.

METHODS

We included consecutive patients (October-November 2018; November-December 2019) admitted to the complex medicine unit providing acute multidisciplinary care for multi-morbid patients (age ≥ 16 years, average age > 80 years). Audit data were collected at ward multidisciplinary meetings and extracted from electronic patient records.

RESULTS

Among 892 patients (mean/SD age = 82.8/8.6, 465 male), 140 (16%) required mental capacity assessment (40/140 (29%) had ≥2 assessments) with 203 assessments in total of which 162 (80%) were done by doctors. Capacity was deemed lacking in 124 (61%) assessments, most commonly in delirium with/without other co-morbid conditions (94/114, 82%) or dementia (9/12, 75%) with lower rates in other disorders (15/27, 56%), and no formal diagnosis of brain/mind disorder (6/50, 12%). Cognitive test scores were overall lower in those lacking capacity (mean/SD abbreviated-mental-test-score = 5.2/2.6, range = 0-10 versus 6.8/2.8, P = 0.001, range = 1-10). Decisions involving discharge planning were most often assessed (48%) followed by treatment (29%), discharge against medical advice (12%) and others (11%).

CONCLUSION

Mental capacity assessments were performed frequently and often repeated, justifying the need for robust training in the practical application of the principles of capacity assessment for staff managing complex older patients.

A Medical Incapacity Hold Policy Reduces Inappropriate Use of Involuntary Psychiatric Holds While Protecting Patients From Harm

BACKGROUND

The use of involuntary psychiatric holds (IPH) to detain patients who lack the capacity to make health care decisions due to nonpsychiatric conditions is common. While this practice prevents patient harm, it also deprives civil liberties, risks liability for false imprisonment, and may hinder disposition. Medical incapacity hold (MIH) policies, which establish institutional criteria and processes for detaining patients who lack capacity but do not meet criteria for an IPH, provide a potential solution.

METHODS

A retrospective chart review was conducted on adult medical/surgical inpatients placed on an IPH or MIH over the 1-year periods before and after implementation of a MIH policy at an academic medical center. The primary outcome was frequency of IPH utilization in patients who did not qualify for an IPH as determined by 2 independent physician reviewers. A Cohen's kappa was calculated to determine inter-rater reliability. Differences in patient demographics and outcomes were compared using a Student's t-test, Wilcoxon rank-sum test, and Pearson chi-square test (α = 0.05).

RESULTS

The Cohen's kappa was 0.72 indicating substantial agreement. Seventy MIHs were placed after implementation (mean duration 4.3 days). Before MIH implementation, 17.6% of IPHs were placed on non-qualifying patients, which decreased to 3.9% following MIH implementation (p < 0.01). The average length of stay for patients on an IPH or MIH did not change following MIH implementation. No instances of patient elopement, grievances, or litigation were found.

CONCLUSION

MIH policies benefit both patients lacking capacity and the health care systems seeking to protect them while avoiding inappropriate use of IPHs.

Legalism, countertransference, and clinical moral perception

This target article focuses on dynamics that arise in three typical ethically complex cases in which psychiatric consultations are requested by physicians: a dying patient refuses life-prolonging treatment, an uncooperative patient demands to be allowed to go outside and smoke, and an angry patient demands to be admitted to the hospital. The discussion canvasses what is at stake morally and clinically in each of these cases and explores clinician-patient interactions, dynamics in relationships between consulting physicians and consultant psychiatrists, patient transference, and physician countertransference. The article defines legalism and countertransference and argues that an ethically and clinically important consequence of these phenomena for patients is distortion of clinicians' perceptions of patients' decisions and vulnerabilities. The discussion also describes how legalism and countertransference adversely affect how clinicians treat their psychiatrist colleagues. Finally, the article suggests how the effects of legalism and countertransference can be mitigated.

Cognitive performance predicts treatment decisional abilities in mild to moderate dementia

OBJECTIVE

To examine the contribution of neuropsychological test performance to treatment decision-making capacity in community volunteers with mild to moderate dementia.

METHODS

The authors recruited volunteers (44 men, 44 women) with mild to moderate dementia from the community. Subjects completed a battery of 11 neuropsychological tests that assessed auditory and visual attention, logical memory, language, and executive function. To measure decision making capacity, the authors administered the Capacity to Consent to Treatment Interview, the Hopemont Capacity Assessment Interview, and the MacCarthur Competence Assessment Tool--Treatment. Each of these instruments individually scores four decisional abilities serving capacity: understanding, appreciation, reasoning, and expression of choice. The authors used principal components analysis to generate component scores for each ability across instruments, and to extract principal components for neuropsychological performance.

RESULTS

Multiple linear regression analyses demonstrated that neuropsychological performance significantly predicted all four abilities. Specifically, it predicted 77.8% of the common variance for understanding, 39.4% for reasoning, 24.6% for appreciation, and 10.2% for expression of choice. Except for reasoning and appreciation, neuropsychological predictor (beta) profiles were unique for each ability.

CONCLUSIONS

Neuropsychological performance substantially and differentially predicted capacity for treatment decisions in individuals with mild to moderate dementia. Relationships between elemental cognitive function and decisional capacity may differ in individuals whose decisional capacity is impaired by other disorders, such as mental illness.

'Refusing treatment--please see': an analysis of capacity assessments carried out by a liaison psychiatry service

The assessment of capacity to consent to a healthcare decision is an important part of day-to-day work in general hospitals. The role of liaison psychiatric services in assessment of capacity has not been well studied in British practice. We looked at all such referrals (35) to a liaison psychiatric service in a teaching hospital in the course of one year. The commonest referrals were regarding capacity to consent to a therapeutic procedure, followed by post-discharge placement and ability to self-discharge. Organic mental disorders were the most frequent cause of incapacity. 20 (57%) of the referrals were for patients who had refused the intervention in question, and in 12 of these the contentious issue was resolved. Liaison psychiatric services can be useful not only in offering a second opinion or clarifying the influence of psychopathology on decision-making ability but also mediating between the patient and the clinical team.

The evaluation of maternal competency

There is limited discussion of maternal competency in the consultation-liaison psychiatry literature. As awareness and reporting of child abuse is increasing, maternal ability to care for newborns is more often called into question. Maternal risk factors for harm and neglect have been identified, and positive signs of maternal ability have also been recognized as important to appraise. Specific domains in the maternal competency exam should be assessed by the psychiatrist, nursing staff, social work staff and pediatrician. The competency exam by the psychiatrist requires a sensitive and nonjudgmental inquiry into maternal behavior and thoughts. The authors present a case study of an inpatient maternal competency consultation that illustrates some of the dilemmas encountered. Future directions should include more involvement by psychiatrists in preventive efforts and interventions that focus on pregnant women at risk in prenatal clinics and in the community.

Competency evaluations on the consultation-liaison service. Some overt and covert aspects

Competency assessments are a growing function of the consultation-liaison (C-L) psychiatrist. Such consultation requests often mask a variety of psychosocial issues that are a source of frustration to the referring physician responding to the pressures of the changing health care delivery system in the acute care setting. This study identifies the issues and the outcome of psychiatric consultation in these patients. The implications of this burgeoning role for the C-L psychiatrist are also explored.
