Incapacity to give informed consent owing to mental disorder

Informed consent in clinical practice: Old problems, new challenges

Informed consent is a fundamental tenet of patient-centred clinical practice as it upholds the ethical principle of patient autonomy and promotes shared decision-making. In the medicolegal realm, failure to meet the accepted standards of consent can be considered as medical negligence which has both legal and professional implications. In general, valid consent requires three core components: (1) the presence of mental capacity - characterised by the patient's ability to comprehend, retain information, weigh options and communicate the decision, (2) adequate information disclosure - based on the 'reasonable physician' or 'reasonable patient' standards and (3) voluntariness in decision-making. Nonetheless, in real-world clinical settings, informed consent is not always optimally achieved, due to various patient, contextual and systemic factors. In this article, I herein discuss three major challenges to informed consent in clinical practice: (1) patient literacy and sociocultural factors, (2) psychiatric illnesses and elderly patients with cognitive impairment and (3) artificial intelligence in clinical care, and sought to offer practical mitigating strategies to address these barriers.

From opt-out to opt-in consent for secondary use of medical data and residual biomaterial: An evaluation using the RE-AIM framework

BACKGROUND

Patient records, imaging, and residual biomaterial from clinical procedures are crucial resources for medical research. In the Netherlands, consent for secondary research has historically relied on opt-out consent. For ethical-legal experts who purport passive consent undermines patient autonomy, opt-in consent (wherein affirmative action is required) is seen as the preferred standard. To date, there is little empirical research exploring patient feasibility, organizational consequences, and the potential risks for research based on secondary data. Thus, we applied the RE-AIM framework to evaluate the impact of migrating from an opt-out to an opt-in consent process.

METHODS

This evaluation was carried out in Radboud University Medical Center, a large tertiary hospital located in the southeast of the Netherlands. All non-acute, mentally competent patients ≥16 years of age registered between January 13, 2020 and June 30, 2023 were targeted (N = 101,437). In line with the RE-AIM framework, individual and organizational consequences were evaluated across five domains: reach, efficacy, adoption, implementation, and maintenance.

RESULTS

101,437 eligible patients were approached of whom 66,214 (65.3%) consented, 8,059 (7.9%) refused consent and 27,164 (26.8%) had no response. Of the 74,273 patients with a response, 89.1% consented to secondary use. The migration to an opt-in consent system was modestly successful; yet notably, differential response patterns by key sociodemographic characteristics were observed. Adaptions to the process flow improved its effectiveness and resulted in a reasonable response over time. Implementation was most affected by budgetary restraints, thus impeding the iterative approach which could have further improved domain outcomes.

CONCLUSION

This evaluation provides an overview of logistical and pragmatic issues encountered when migrating from opt-out to opt-in consent. Response bias remains a major concern. Though not always directly transferable, these lessons can be broadly used to inform other health care organizations of the potential advantages and pitfalls of an opt-in consent system.

Introduction of a Novel Ethics Curriculum to the Third-Year Psychiatry Clerkship Experience

OBJECTIVE

The purpose of this study was to determine if a brief ethics curriculum embedded in a third-year required clerkship differentially impacted students' self-rated confidence versus competence (determined by a written examination) regarding ethical principles related to psychiatry.

METHODS

Using a naturalistic design, 270 medical students at the University of Washington were assigned to one of three groups during their third-year psychiatry clerkship: a control group with no additional ethics content, a group with access to a pre-recorded video ethics curriculum, or a group with live didactic sessions in addition to the video curriculum. All students took a pre- and post-test that assessed their confidence and competence in ethical theory and behavioral health ethics.

RESULTS

Confidence and competence were not statistically different across the three groups prior to completing the curriculum (p > 0.1). Post-test scores on confidence in behavioral health ethics were not significantly different between the three groups (p > 0.05). Post-test scores on confidence in ethical theory were significantly higher in the video-only and video + discussion group as compared to the control group (3.74 ± 0.55 and 4.00 ± 0.44 vs. 3.19 ± 0.59 respectively; p < 0.0001). Both the video-only and video + discussion group showed greater improvement in competence in ethical theory and application than the control group (0.68 ± 0.30 and 0.76 ± 0.23 vs. 0.31 ± 0.33, respectively; p < 0.0001) and behavioral health ethics (0.79 ± 0.14 and 0.85 ± 0.14 vs. 0.59 ± 0.15, respectively; p < 0.002).

CONCLUSIONS

With the addition of this ethics curriculum, students showed both increased confidence and competence in their ability to analyze ethical situations as well as increased competence regarding behavioral health ethics.

Is self-inflicted amputation to the upper extremity a contraindication to replantation?

PURPOSE

Contraindications to replantation include severe medical or psychiatric comorbidities. Recently, authors have suggested that due to the improving therapeutic options for patients with psychiatric decompensation, this should no longer be listed as a contraindication to replantation. Despite this, authors continue to list severe psychiatric comorbidities as a contraindication to replantation. This case series and review of the literature discusses this complex topic and provides recommendations regarding the management of patients following upper extremity self-inflicted amputations.

METHODS

The authors present two cases of self-inflicted upper extremity amputations. The cases depict the acute management and the outcomes of these patients. The authors also reviewed the literature to present the available literature on this topic.

RESULTS

The first case is a 64-year-old male who deliberately amputated his left hand with a table saw while suffering postictal psychosis. He underwent replantation. The patient was co-managed by the surgical and psychiatric team postoperatively. The patient expressed gratitude for his replantation after being treated for his psychoneurological condition. The second case is that of a 25-year-old male who deliberately amputated his left forearm using a Samurai sword. The patient's limb was successfully replanted. In the post-anesthesia care unit, the patient experienced extreme agitation, and during this event, he reinjured the left forearm. He was again taken urgently to the operating room to revise the replantation. Once psychiatrically stabilized, the patient was thankful for the care he received.

CONCLUSION

The management of upper extremity self-inflicted amputations is controversial and difficult to establish as this presentation is rare. We present two cases which illustrate some of the nuances in the care of these patients. Our review suggests that psychiatric diagnosis be viewed as a comorbidity and not a contraindication to replantation. Thus, an informed consent discussion should be performed with the patients and, as needed, a member of the psychiatric team in order to decide whether to replant or not.

Algorithmic Assessments in Deciding on Voluntary, Assisted or Involuntary Psychiatric Treatment

The challenges in assessing whether psychiatric treatment should be provided on voluntary, assisted or involuntary legal bases prompted the development of an assessment algorithm that may aid clinicians. It comprises a part that assesses the incapacity to provide informed consent to treatment, care or rehabilitation. It also captures the patient’s willingness to receive these treatments, the risk posed to the patient’s health or safety, financial interests or reputation and risks of serious harm to self or others. By following various decision paths, the algorithm yields one of four legal states: a voluntary, assisted, or involuntary state or that the proposed intervention should be declined. This study examined the predictive validity and the reliability of this algorithm. It was applied 4052 times to 135 clinical case narratives by 294 research participants. The legal states yielded by the algorithm had high statistical significance when matched with the gold standard (Chi-squared = 6963; df = 12; p < 0.001). It was accurate in yielding the correct legal state for the voluntary, assisted, involuntary and decline categories in 94%, 92%, 88% and 86% of the clinical case narratives, respectively. For internal reliability, a correspondence model accounted for 99.8% of the variance by which the decision paths clustered together fittingly with each of the legal states. Inter-rater reliability testing showed a moderate degree of agreement among participants on the suitable legal state (Krippendorff’s alpha = 0.66). These results suggest the algorithm is valid and reliable, which warrant a subsequent randomised controlled study to investigate whether it is more effective in clinical practice than standard assessments.

The Network of Services for COVID-19 Vaccination in Persons With Mental Disorders: The Italian Social Health System, Its Organization, and Bioethical Issues

The adoption of restrictive measures aimed at curtailing the spread of SARS-CoV2 has had a harmful impact on socio-affective relationships, while limiting the scope of interventions and activities to promote social inclusion, with considerable negative repercussions for patients with mental disorders. Vaccination has been and will continue to be a valid tool to overcome the barriers of social isolation and to protect the health of this category of patients. In this paper we present an overview of the Italian network of social and healthcare services for COVID-19 vaccination among patients with mental disorders. Some aspects of medical ethics are discussed in order to share good practices for improving the health of this vulnerable group of people. We then consider the measures implemented by the health system in Italy to deal with the phenomenon of vaccine hesitancy before addressing the issue of autonomy and restricted access to vaccination points. Finally, we illustrate some of the perspectives already adopted by the Italian system, which may be useful to the global scientific community.

Navigating the Minefield: Managing Refusal of Medical Care in Older Adults with Chronic Symptoms of Mental Illness

Purpose

The purpose of this case series is to illustrate the complexity of considerations across health (physical and mental), ethical, human rights and practical domains when an older adult with chronic symptoms of mental illness refuses treatment for a serious medical comorbidity. A broad understanding of these considerations may assist health care professionals in navigating this challenging but common aspect of clinical practice.

Case Presentation

Three detailed case reports are described. Participants were older adults with an acute presentation of a chronic mental illness, admitted to a specialized older persons mental health inpatient unit (OPMHU) in an Australian metropolitan hospital. Significant comorbid medical issues were detected or arose during the admission and the patient refused the recommended medical intervention. Data extracted from patients' medical records were analyzed and synthesized into detailed case reports using descriptive techniques. Each patient was assessed as lacking capacity for healthcare and treatment consent and did not have relatives or friends to assist with supported decision-making. Multifaceted aspects of decision-making and management are highlighted.

Conclusion

There are multiple complex issues to consider when an older adult with chronic symptoms of mental illness refuses treatment for serious comorbid medical conditions. In addition to optimizing management of the underlying mental illness (which may be impairing capacity to make healthcare decisions), clinicians should adopt a role of advocacy for their patients in considering the potential impact of ageism and stigma on management plans and inequities in physical healthcare. Consultation with specialist medical teams should incorporate multifaceted considerations such as potentially inappropriate treatment and optimum setting of care. Equally important is reflective practice; considering whether treatment decisions may infringe upon human rights or cause trauma.

The Challenges Faced by Mental Health Care Users in a Primary Care Setting: A Qualitative Study

Over the past two decades, the value and benefits of integrated mental health care services have been increasingly recognised. Despite the potential benefits, barriers exist at primary care level to receiving mental health care services, interfering with continuity of care. We conducted semi-structured interviews with mental healthcare users at a primary care clinic in South Africa, to explore their experiences of receiving mental health care services. A convenience sample of 15 participants identified challenges such as limited infrastructure, organisation, medication, services in local communities, allied mental health care services, communication and long waiting times. Mental health care users felt uncared for and disrespected, especially if they were treated by unskilled and overworked staff. Mental health care users described clinic visits as stressful and frustrating. Mental health care users described marked challenges in mental health care service provision in a South African primary health care setting.

The notion of free will and its ethical relevance for decision-making capacity

Background

Obtaining informed consent from patients is a moral and legal duty and, thus, a key legitimation for medical treatment. The pivotal prerequisite for valid informed consent is decision-making capacity of the patient. Related to the question of whether and when consent should be morally and legally valid, there has been a long-lasting philosophical debate about freedom of will and the connection of freedom and responsibility.

Main text

The scholarly discussion on decision-making capacity and its clinical evaluation does not sufficiently take into account this fundamental debate. It is contended that the notion of free will must be reflected when evaluating decision-making capacity. Namely, it should be included as a part of the appreciation-criterion for decision-making capacity. The argumentation is mainly drawn on the compatibilism of Harry Frankfurt.

Conclusions

A solution is proposed which at the same time takes the notion of free will seriously and enriches the traditional understanding of decision-making capacity, strengthening its justificatory force while remaining clinically applicable.

Autonomy in Depressive Patients Undergoing DBS-Treatment: Informed Consent, Freedom of Will and DBS' Potential to Restore It

According to the World Health Organization, depression is one of the most common and most disabling psychiatric disorders, affecting at any given time approximately 325 million people worldwide. As there is strong evidence that depressive disorders are associated with a dynamic dysregulation of neural circuits involved in emotional processing, recently several attempts have been made to intervene directly in these circuits via deep brain stimulation (DBS) in patients with treatment-resistant major depressive disorder (MDD). Given the promising results of most of these studies, the rising medical interest in this new treatment correlates with a growing sensitivity to ethical questions. One of the most crucial concerns is that DBS might interfere with patients' ability to make autonomous decisions. Thus, the goal of this article is to evaluate the impact DBS presumably has on the capacity to decide and act autonomously in patients with MDD in the light of the autonomy-undermining effects depression has itself. Following the chronological order of the procedure, special attention will first be paid to depression's effects on patients' capacity to make use of their free will in giving valid Informed Consent. We suggest that while the majority of patients with MDD appear capable of autonomous choices, as it is required for Informed Consent, they might still be unable to effectively act according to their own will whenever acting includes significant personal effort. In reducing disabling depressive symptoms like anhedonia and decrease of energy, DBS for treatment resistant MDD thus rather seems to be an opportunity to substantially increase autonomy than a threat to it.

Presumed consent: licenses and limits inferred from the case of geriatric hip fractures

BACKGROUND

Hip fractures are common and serious injuries in the geriatric population. Obtaining informed consent for surgery in geriatric patients can be difficult due to the high prevalence of comorbid cognitive impairment. Given that virtually all patients with hip fractures eventually undergo surgery, and given that delays in surgery are associated with increased mortality, we argue that there are select instances in which it may be ethically permissible, and indeed clinically preferable, to initiate surgical treatment in cognitively impaired patients under the doctrine of presumed consent. In this paper, we examine the boundaries of the license granted by presumed consent and use the example of geriatric hip fracture to build an ethical framework for understanding the doctrine of presumed consent.

DISCUSSION

The license to act under presumed consent requires three factors: patient incapacity, clinical urgency and clarity on the correct course of action. All three can apply to geriatric hip fracture. The typical patient frequently lacks capacity. Delays in initiating surgical treatment are associated with markedly increased mortality rates. Last, there appears to be consensus that surgery is the preferred treatment. Nonetheless, because there is a window of safe delay during which treating physicians can stabilize the patient, address reversible causes of cognitive impairment and identify surrogate decision makers, presumed consent should be invoked only as a method of last resort.

CONCLUSIONS

A medical situation need not be characterized by risk of imminent and certain death for presumed consent to be relevant. Rather, there are two distinct windows that must be considered: the time interval in which action may be delayed without danger, and the time interval needed to obtain a better form of consent. Presumed consent is appropriate only when the latter exceeds the former.

Under the banyan tree--exclusion and inclusion of people with mental disorders in rural North India

Background

Social exclusion is both cause and consequence of mental disorders. People with mental disorders (PWMD) are among the most socially excluded in all societies yet little is known about their experiences in North India. This qualitative study aims to describe experiences of exclusion and inclusion of PWMD in two rural communities in Uttar Pradesh, India.

Methods

In-depth interviews with 20 PWMD and eight caregivers were carried out in May 2013. Interviews probed experiences of help-seeking, stigma, discrimination, exclusion, participation, agency and inclusion in their households and communities. Qualitative content analysis was used to generate codes, categories and finally 12 key themes.

Results

A continuum of exclusion was the dominant experience for participants, ranging from nuanced distancing, negative judgements and social isolation, and self-stigma to overt acts of exclusion such as ridicule, disinheritance and physical violence. Mixed in with this however, some participants described a sense of belonging, opportunity for participation and support from both family and community members.

Conclusions

These findings underline the urgent need for initiatives that increase mental health literacy, access to services and social inclusion of PWMD in North India, and highlight the possibilities of using human rights frameworks in situations of physical and economic violence. The findings also highlight the urgent need to reduce stigma and take actions in policy and at all levels in society to increase inclusion of people with mental distress and disorders.

Protecting prisoners' autonomy with advance directives: ethical dilemmas and policy issues

Over the last decade, several European countries and the Council of Europe itself have strongly supported the use of advance directives as a means of protecting patients' autonomy, and adopted specific norms to regulate this matter. However, it remains unclear under which conditions those regulations should apply to people who are placed in correctional settings. The issue is becoming more significant due to the increasing numbers of inmates of old age or at risk of suffering from mental disorders, all of whom might benefit from using advance directives. At the same time, the closed nature of prisons and the disparate power relationships that characterise them mean that great caution must be exercised to prevent care being withdrawn or withheld from inmates who actually want to receive it. This paper explores the issue of prisoners' advance directives in the European context, starting with the position enshrined in international and European law that prisoners retain all their human rights, except the right to liberty, and are therefore entitled to self-determination regarding health care decisions.

The patient/client/consumer/service user and medical ethics 40 years on

This essay, written from my non-doctor's 'lay' perspective, sketches a gradually improving approach to medical ethics over the 40-year period since this journal was founded. A central feature of this improvement has been the increasing focus of medical ethics on the interests and perspectives of the patients/clients/consumers/service users, whose interests doctors and other healthcare workers serve. Events such as misuse of the end of life 'Liverpool Care Pathway' and the shockingly poor care revealed in National Health Service hospitals in Mid-Staffordshire show that these improvements are by no means universal. Nonetheless, there has been a steady improvement in general terms towards putting patients first and it is not flattery to say that in its consistent support for this concern and in its promotion of non-medical involvement in medical ethics education the Journal of Medical Ethics has itself made a significant contribution to 'doing good medical ethics'.

Methodological issues in defining aggression for content analyses of sexually explicit material

There exists an important tradition of content analyses of aggression in sexually explicit material. The majority of these analyses use a definition of aggression that excludes consent. This article identifies three problems with this approach. First, it does not distinguish between aggression and some positive acts. Second, it excludes a key element of healthy sexuality. Third, it can lead to heteronormative definitions of healthy sexuality. It would be better to use a definition of aggression such as Baron and Richardson's (1994) in our content analyses, that includes a consideration of consent. A number of difficulties have been identified with attending to consent but this article offers solutions to each of these.

Severity of psychotic episodes in predicting concurrent depressive and anxiety features in acute phase schizophrenia

BACKGROUND

Considering that depressive and anxiety symptoms are common in schizophrenia, this study investigated whether the severity of a psychotic episode in an acute phase schizophrenia cohort is predictive of concurrent depressive and anxiety features.

METHOD

Fifty one recently hospitalised patients suffering from acute phase schizophrenia participated prospectively in a cross-sectional study. The severity of the psychotic episode, the depressive features and the anxiety features were measured by the Structured Clinical Interview for Positive and Negative Syndrome Scale (SCI-PANSS), the Calgary Depression Scale for Schizophrenia (CDSS), the Hamilton Anxiety Rating Scale (HAM-A) and the Staden Schizophrenia Anxiety Rating Scale (S-SARS). The total SCI-PANSS-scores were adjusted to exclude appropriately the depression or anxiety items contained therein. To examine akathisia as potential confounder, the Barnes Akathisia Scale was also applied. The relationships were examined using linear regressions and paired t-tests were performed between lower and higher scores on the SCI-PANSS.

RESULTS

A higher adjusted total SCI-PANSS-score predicted statistically significantly higher scores for depressive features on the CDSS (p < 0.0001) and for anxiety features on the HAM-A (p = 0.05) and the S-SARS (p < 0.0001). The group that scored more or equal to the median (=99) of the adjusted total SCI-PANSS, scored significantly higher (p < 0.0001) on the CDSS, the HAM-A and the S-SARS than the group scoring below it. Akathisia measured distinctly different (p < 0.0001) from both the anxiety measures.

CONCLUSION

The study suggests that the severity of a psychotic episode in acute phase schizophrenia predicts the severity of concurrent depressive and anxiety features respectively.

Health behaviors as conceptualized by individuals diagnosed with a psychotic disorder

The purpose of this study is to describe health behaviors as conceptualized by individuals diagnosed with a psychotic disorder. Data were collected by qualitative interviews (n = 20) and were analyzed using phenomenography. Mental well-being took priority over physical health and guided health behaviors. Social relations were significant, and when they proved insufficient, health care professionals were utilized as a substitute. Some relied on religion, complementary treatments, and folk beliefs for health. Interventions not dependent on mental well-being, and assisting individuals to participate in appropriate networks could have advantages. Interventions adapted to the individual's financial situation and cultural values are useful as issues related to these areas can obstruct implementation of health behaviors. Implementing the findings of this study in nursing research and education will prepare nurses to meet the varying health needs of different individuals.

Beliefs about health, health risks and health expectations from the perspective of people with a psychotic disorder

AIM

To examine beliefs about health, health risks and health expectations from the perspective of people diagnosed with a psychotic disorder.

BACKGROUND

People with psychotic disorders have a threefold higher risk of developing physical health problems than the general population, and prevention of these problems is warranted. Examining patients´ health beliefs could help deepen our understanding of how to plan successful health interventions with this group.

METHODS

Qualitative semi-structured interviews were conducted from November 2010 to October 2011 with 17 people with psychotic disorders. Data were analyzed using a qualitative content analysis.

RESULTS

An overall positive picture of health was found despite the fact that physical health was found to be hard to verbalize and understand. Health was mainly associated with psychological wellbeing, while health risks were found to be related to uncertain bodily identity, troublesome thoughts and inner voices, and exclusion from society. Interest in learning, and visions and goals of health seemed to increase awareness of health risks and health expectations, while not worrying could be viewed as a hindrance for health expectations.

CONCLUSION

There is a lack of expressed awareness of physical health risks, but such awareness is fundamental to performing life-style changes [14]. Nurses thus have an important task to help patients understand and verbalize potential physical health risks, and to find out what motivates them to adopt health behaviors.

Preliminary Turkish study of psychiatric in-patients' competence to make treatment decisions

INTRODUCTION

Competence is a prerequisite for informed consent. Patients who are found to be competent are entitled to accept or refuse the proposed treatment. In recent years, there has been an increased interest in studies examining competence for treatment in psychiatric patients. In this study, we aimed to investigate the decision-making competencies of inpatients with a range of psychiatric diseases.

METHODS

This study was carried out at the psychiatry clinic of Kocaeli University Hospital in Turkey from June 2007 to February 2008. Decision-making competence was assessed in 83 patients using the MacArthur Competence Assessment Tool-Treatment (MacCAT-T).

RESULTS

The study groups consisted of patients with mood (39.8%), psychotic (27.7%) and anxiety disorders (18.1%), and alcohol/substance addiction (14.5%). There was a significant relation between decision-making competence and demographic and clinical characteristics. Appreciation of the given information was more impaired in psychotic disorder patients than in other patients, but understanding and reasoning of the given information was similar in all groups.

DISCUSSION

These results reveal the importance of evaluating decision-making competencies of psychiatric patients before any treatment or intervention is carried out to ascertain their ability to give informed consent to treatment. Institutional and national policies need to be determined and put into practice relating to the assessment and management of competence in patients with psychiatric disorders.

A systematic review of the literature about competence and poor insight

OBJECTIVE

  Formally, incompetence implies that a patient cannot meet the legal requirements for informed consent. Our aim was to review the scientific literature on the relationship between competence and insight in patients with psychiatric disorders, how competence and insight are connected in these patients and whether there are differences in competence and insight among patients with different disorders.

METHOD

  A search in PubMed/Medline was performed. Articles were assessed on relevance criteria by two independent reviewers. Study design, population, variables, and outcomes were extracted.

RESULTS

  Seven articles were included on studies of psychiatric inpatients and outpatients and of psychotic and non-psychotic patients. All studies used the MacArthur Competence Assessment Tool (MacCAT). All studies but one found a strong correlation between poor insight and incompetence. Psychotic patients with poor insight are very likely to be incompetent, and psychotic patients with adequate insight are generally competent. One well-executed study showed that in non-psychotic disorders, however, another relationship emerges; competence and insight do not completely overlap in these patients.

CONCLUSION

  Most incompetent psychotic patients have poor insight, but non-psychotic patients with adequate insight were incompetent in a substantial number of cases. In sum: non-psychotic patients with adequate insight can be incompetent.

The assessment of decisional capacity

The physician must explain the treatment or procedure in detail including risks, benefits, and alternative options; the patient's choice must be voluntary; the patient must demonstrate his or her ability to understand the risks and benefits of their choice; and the patient must be able to manipulate information in a logical way. These criteria must be met in order for the process of informed consent to be valid.

Acceptance and insight: incapacity to give informed consent

PURPOSE OF REVIEW

To highlight areas for potential refinement in assessments of capacity to give informed consent.

RECENT FINDINGS

The clinical assessment of the patient's capacity to give informed consent may be informed and guided by sophisticated criteria or assessment instruments. The approach of most assessment instruments and the literature on (in)capacity departs from the abilities that underpin giving informed consent. This approach may be refined, however, by assessing clinically for a causal connection between the mental disorder in the mind of a particular person and the particular inability. It may furthermore be refined by assessing that aspect of insight that is best connected to incapacity, for insight has been found to be the best clinical discriminator of capacity status in patients with psychotic and manic disorders.

SUMMARY

To find that a person is incapable by virtue of a mental disorder, a causal connection between the mental disorder and the particular inability should be assessed clinically for the very patient. Furthermore, the term 'acceptance' is more apt than 'appreciation' and 'belief' in capturing that aspect of insight by which a person with psychotic and manic disorders may be rendered incapable of giving informed consent.

Accept or refuse? A pilot study of patients' perspective on participating as imaginary research subjects in schizophrenia

OBJECTIVE

The goal of the present study was to evaluate demographic and clinical factors that affect the intention to participate in commonly-conducted research in patients with schizophrenia.

METHODS

Thirty-four outpatients with a diagnosis of schizophrenia were enrolled in this study. They were asked whether they would have any intention to participate in four imaginary studies: a simple questionnaire, a genetic study, a study of complex tasks and a risky study. We analyzed the differences in general psychopathology, insight and demographic characteristics of the participants according to their responses (acceptance or refusal) to the four proposed studies.

RESULTS

Younger and better-educated patients tended to decline participation in a risky study. Patients with a longer duration of regular psychiatric follow-ups tended to willingly participate in the simple questionnaire. There were no overall statistical differences in general psychopathology and insight between patients who agreed or declined to participate in studies.

CONCLUSION

Age and education level may be factors that influence decisions to participate in schizophrenia studies. Further research is needed to confirm and expand on the current findings.

The need for additional safeguards in the informed consent process in schizophrenia research

The process of obtaining informed consent to participate in a clinical study presents many challenges for research conducted in a population of patients with schizophrenia. Morally valid, informed consent must include information sharing, decisional capacity, and capacity for voluntarism. This paper examines the unique features of schizophrenia that may threaten each of these elements of informed consent, and it proposes additional safeguards in the process of gaining informed consent from individuals with schizophrenia in order to maximise the decision-making potential of this patient population.

Dysrhythmogenic potential in acute admissions to psychiatric hospitals and clinics

Co-morbidity between physical disease, especially cardiovascular, and psychological disturbances is well documented. In psychiatric patients, the potential for dysrhythmogenic incidences is increased by the fact that many psychiatric medications influence cardiovascular function.

AIM

The aim of the study was to examine the dysrhythmogenic potential of 30 psychiatric patients (group A), irrespective of diagnoses or medication, at admission to psychiatric institutions.

METHODS

The dysrhythmogenic potential was determined in terms of heart rate-corrected QT intervals (QTc), heart rate-corrected JT intervals (JTc), QT and JT dispersion (QTcd and JTcd) between leads V1 and V6, and heart rate variability (HRV) as determined from lead V6 of the ECG. Values were compared with 30 age- and gender-matched controls (group B). In the second part of the study the dysrhythmogenic indicators were assessed in a patient group (group C; n = 43) with only psychiatric disorders and compared to a group with psychiatric as well as medical disorders (group D; n = 27).

RESULTS

The patient group A had significantly higher values than the control group for mean QTc (V6) (0.4579 +/- 0.0328 vs 0.4042 +/- 0.0326; p = 0.0470), mean JTc (V6) (0.3883 +/- 0.0348 vs 0.3064 +/- 0.0271; p = 0.0287) and mean QT and JT dispersion values (QTcd = 0.0443 +/- 0.0203 vs 0.0039 +/- 0.0053 and JTcd = 0.0546 +/- 0.1075 vs 0.0143 +/- 0.1450, p < 0.05). A statistically significant difference (p < 0.0001) was found between the patients' (group A) HRV and that of the controls (group B). No statistically significant differences were found between the values of the dysrhythmogenic indicators for patients with only psychiatric illness (group C) and those with psychiatric as well as medical disorders (group D).

CONCLUSIONS

Psychiatric patients at the point of admission to psychiatric institutions may have an increased dysrhythmogenic potential, not necessarily caused by physical disease. The potential of an augmented risk for cardiovascular incidents in psychiatric patients should be considered when treating such patients.

Balancing autonomy and risk: a failure of nerve in England and Wales?

Specialised mental health legislation typically provides for the hospitalisation and treatment of those with mental disorders in the absence of their consent. The article examines the possible justifications for the existence of these special powers and argues that two of the most common justifications, the protection of the patient and the protection of others, do discriminate against those with a mental, as opposed to a physical, disorder. The relationship between mental health and mental capacity, or guardianship, legislation is then considered and possible ways forward are discussed with particular reference to the current reform debate in England and Wales.

Professional-patient relationships and informed consent

Four theoretical ethical perspectives on professional-patient relationships-autonomy, justice, virtue ethics, and the ethic of care-are surveyed, and some of their implications for the informed consent requirement in health care are sketched out. The practical issues of competence to consent, adequate information, and voluntariness are reviewed, and examples are given of the ways in which the theoretical perspectives outlined earlier might inform practice in areas such as these. Finally, the situation of patients not competent to consent is considered in the light of the same theoretical perspectives.

Changes in semantic uses of first person pronouns as possible linguistic markers of recovery in psychotherapy

OBJECTIVE

To examine changes in linguistic markers in the course of psychotherapy, drawing on Frege's logic of relations to define semantic variables distinct from syntactic variables.

METHOD

From a sample of 73 patients, 10 patients with the best and 10 patients with the worst outcomes were selected. Forty transcribed sessions of each outcome group were compared statistically for change between commencement and termination of psychotherapy in: (i) the syntactic usage of first person pronouns ('I', 'me', 'we', 'us', 'implied I', 'implied me'); (ii) semantic usage of first person pronouns (expressing alpha, omega, or unclear positions); and (iii) non-pronoun linguistic variables (passive voice, negative, copula, auxiliary verbs expressing a sense of obligation).

RESULTS

There were no significant differences between the best and worst outcome groups in the change of either syntactic usage, or of the non-pronoun linguistic variables. However, the outcome groups differed significantly in the change of their semantic usage (alpha: p = 0.002; omega: p = 0.028): The best outcome group showed an increase of alpha positions and a decrease of omega positions, whereas the worst outcome group showed the inverse (i.e. decrease of alpha and increase of omega positions).

CONCLUSIONS

Results suggest only semantic, that is meaning-driven, usage of first person pronouns marks recovery in the course of psychotherapy. If replicated, this finding could be used to monitor treatment responses. Replication in other kinds of treatment could mean these semantic changes are markers of recovery more generally than in psychotherapy.
