Relational ethics of delirium care: Findings from a hospice ethnography

Delirium, a common syndrome in terminally ill people, presents specific challenges to a good death in end‐of‐life care. This paper examines the relational engagement between hospice nurses and their patients in a context of end‐of‐life delirium. Ethnographic fieldwork spanning 15 months was conducted at a freestanding residential hospice in eastern Canada. A shared value system was apparent within the nursing community of hospice; patients’ comfort and dignity were deemed most at stake and therefore commanded nurses’ primary attention. This overarching commitment to comfort and dignity shaped all of nursing practice in this hospice, including practices related to end‐of‐life delirium. The findings of this study elaborate the ways in which hospice nurses interpreted and responded to the discomfort of their patients in delirium, as well as the efforts they made to understand their patients’ subjective experiences and to connect with them in supportive ways. In addition to what is already known about clinical assessment and treatment of delirium in palliative care settings, the findings of this study offer points of reflection for nurses anywhere who are contending with the relational challenges that delirium presents in end‐of‐life care.     

Précising definitions as a way to combat overdiagnosis

Roughly, overdiagnosis (ODx) occurs when people are harmed by receiving diagnoses (often accompanied by interventions) that do not benefit them, usually because the diagnosed conditions do not pose a threat to their health. ODx is a theoretical as well as a practical problem as it relates to definitions of disease. Elsewhere, it has been argued that disease is a vague concept and that this vagueness may contribute to ODx. In response, we develop a stipulative or précising definition of disease, for the specific purpose of decreasing or preventing ODx. We call this disease_ODx, aimed at distinguishing cases where it would be beneficial to identify (and treat the condition) from those where diagnosis is more likely to harm than benefit. A preliminary definition of disease_ODx is that X is a disease_ODx iff there is dysfunction that has a significant risk of causing severe harm. This paper examines the 3 concepts in this definition, using a naturalistic account of function, a Feinbergian account of comparative harm, and a probabilistic understanding of risk. We then test the utility of this approach using examples of clinical conditions that are currently overdiagnosed.     

Factors influencing secondary care pharmacist and nurse independent prescribers’ clinical reasoning: An interprofessional analysis

In the United Kingdom, pharmacist and nurse independent prescribers are responsible for both the clinical assessment of and prescribing for patients. Prescribing is a complex skill that entails the application of knowledge, skills, and clinical reasoning to arrive at a clinically appropriate decision. Decision-making is influenced and informed by many factors. This study, the first of its kind, explores what factors influence pharmacist and nurse independent prescribers during the process of clinical reasoning. A think-aloud methodology immediately followed by a semi-structured interview was conducted with 11 active nurse and 10 pharmacist independent prescribers working in secondary care. Each participant was presented with validated clinical vignettes for the think-aloud stage. Participants chose the clinical therapeutic areas for the vignettes, based on their self-perceived competencies. Data were audio-recorded, transcribed verbatim, and a constant-comparative approach was used for analysis. Influences on clinical reasoning were broadly categorised into themes: social interaction, intrinsic, and contextual factors. These themes showed that intrinsic, sociocultural, and contextual aspects heavily influenced the clinical reasoning processes of prescribers. For example, prescribers were aware of treatment pathways, but chose to refer patient cases to avoid making the final prescribing decision. Exploration of this behaviour in the interviews revealed that previous experience and attitudes such as confidence and cautiousness associated with responsibility were strong influencers within the decision-making process. In addition, strengthening the professional identity of prescribers could be achieved through collaborative work with interprofessional healthcare teams to orient their professional practice from within the profession. Findings from this study can be used to inform the education, training, and practice of independent prescribers to improve healthcare services by improving their professional and interprofessional development.     

Exploring the Role of Negative Cognitions in the Relationship Between Ethnicity,Sleep, and Pain in Women With Temporomandibular Joint Disorder

Negative cognitions are central to the perpetuation of chronic pain and sleep disturbances. Patients with temporomandibular joint disorder (TMJD), a chronic pain condition characterized by pain and limitation in the jaw area, have a high comorbidity of sleep disturbances that possibly exacerbate their condition. Ethnic group differences are documented in pain, sleep, and coping, yet the mechanisms driving these differences are still unclear, especially in clinical pain populations. We recruited 156 women (79% white, 21% African American) diagnosed with TMJD as part of a randomized, controlled trial evaluating the effectiveness of interventions targeting sleep and pain catastrophizing on pain in TMJD. Analysis of baseline data demonstrated that, relative to white participants, African Americans exhibited higher levels of clinical pain, insomnia severity, and pain catastrophizing, yet there was no ethnic group difference in negative sleep-related cognitions. Mediation models revealed pain catastrophizing, but not sleep-related cognitions or insomnia severity, to be a significant single mediator of the relationship between ethnicity and clinical pain. Only the helplessness component of catastrophizing together with insomnia severity sequentially mediated the ethnicity–pain relationship. These findings identify pain catastrophizing as a potentially important link between ethnicity and clinical pain and suggest that interventions targeting pain-related helplessness could improve both sleep and pain, especially for African American patients.Perspective:Pain-related helplessness and insomnia severity contribute to ethnic differences found in clinical pain among woman with TMJD. Findings can potentially inform interventions that target insomnia and catastrophizing to assist in reducing ethnic disparities in clinical pain.     

Headaches in Patients with Pituitary Tumors: a Clinical Conundrum

Purpose of Review

Pituitary tumors account for approximately 17% of all intracranial neoplasms, with the majority being pituitary adenomas. Often, these are found incidentally during a workup for headache; however, the relationship between symptom and pathology remains unclear. The purpose of this article is to review the most recent literature on the epidemiology, pathophysiology, and management of headaches in patients with pituitary tumors.

Recent Findings

The current literature is limited, with few prospective trials focusing on this question. With the exception of pituitary apoplexy, the relationship between headaches and pituitary masses remains unclear. Intervention does not always improve headache and can lead to development of new headache syndromes.

Summary

Further research is needed to better elucidate the relationship between pituitary tumors and headaches. Headache alone is rarely an indication for surgical management of a pituitary adenoma.

     

Psychometric testing of the healthy eating and physical activity self‐efficacy questionnaire and the healthy eating and physical activity behavior recall questionnaire for children

1 Purpose

The purpose of this study was to develop and assess the psychometric properties for two related questionnaires: the Healthy Eating and Physical Activity Self‐Efficacy Questionnaire for Children (HEPASEQ‐C) and the Healthy Eating and Physical Activity Behavior Recall Questionnaire for Children (HEPABRQ‐C).

2 Design and Methods

HEPASEQ‐C and HEPABRQ‐C were administered to 517 participating children with 492 completing. Data were analyzed to evaluate for reliability and validity of the questionnaires.

3 Results

Content validity was established through a 10‐person expert panel. For the HEPASEQ‐C, item content validity index (CVI) ranged from 0.80 to 1.00. The CVI for the total questionnaire was 1.0. All HEPASEQ‐C items loaded on a single factor. Cronbach's alpha was deemed acceptable (.749). For the HEPABRQ‐C, item CVI ranged from 0.88 to 1.00. CVI for the total questionnaire was 1.0. Pearson product moment correlation between HEPASEQ‐C and HEPABRQ‐C scores was significant (r = .501, p = .000).

4 Practice Implications

The HEPASEQ‐C and HEPABRQ‐C are easily administered and provide helpful insights into children's self‐efficacy and behavior recall. They are easy to use and applicable for upper elementary school settings, in clinical settings for individual patients, and in health promotion settings.
