How do palliative care doctors recognise imminently dying patients? A judgement analysis.

ABSTRACT:

Objectives

To identify a group of palliative care doctors who perform well on a prognostic test and to understand how they make their survival predictions.

Design

Prospective observational study and two cross-sectional online studies.

Setting

Phase I: an online prognostic test, developed from a prospective observational study of patients referred to palliative care. Phase II: an online judgement task consisting of 50 hypothetical vignettes.

Participants

All members of the Association of Palliative Medicine (APM) were eligible (n=~1100). 99 doctors completed the prognostic test and were included in the phase I analysis. The top 20% were invited to participate in phase II; 14/19 doctors completed the judgement task and were included in the phase II analysis.

Measures

Phase I: participants were asked to give a probability of death within 72?hours (0%-100%) for all 20 cases. Accuracy on the prognostic test was measured with the Brier score which was used to identify the 'expert' group (scale range: 0 (expert)-1 (non-expert)). Phase II: participants gave a probability of death within 72?hours (0%-100%). A mixed model regression analysis was completed using the percentage estimate as the outcome and the patient information included in the vignettes as the predictors.

Results

The mean Brier score of all participants was 0.237 (95% CI 0.235 to 0.239). The mean Brier score of the 'experts' was 0.184 (95% CI 0.176 to 0.192). Six of the seven prognostic variables included in the hypothetical vignettes were significantly associated with clinician predictions of death. The Palliative Performance Score was identified as being the most influential in the doctors' prognostic decision making (?=0.48, p<0.001).

Conclusions

This study identified six clinical signs and symptoms which influenced the judgement policies of palliative care doctors. These results may be used to teach novice doctors how to improve their prognostic skills.

Project description:ObjectiveTo examine how palliative medicine doctors engage patients in end-of-life (hereon, EoL) talk. To examine whether the practice of "eliciting and responding to cues", which has been widely advocated in the EoL care literature, promotes EoL talk.DesignConversation analysis of video- and audio-recorded consultations.ParticipantsUnselected terminally ill patients and their companions in consultation with experienced palliative medicine doctors.SettingOutpatient clinic, day therapy clinic, and inpatient unit of a single English hospice.ResultsDoctors most commonly promoted EoL talk through open elaboration solicitations; these created opportunities for patients to introduce-then later further articulate-EoL considerations in such a way that doctors did not overtly ask about EoL matters. Importantly, the wording of elaboration solicitations avoided assuming that patients had EoL concerns. If a patient responded to open elaboration solicitations without introducing EoL considerations, doctors sometimes pursued EoL talk by switching to a less participatory and more presumptive type of solicitation, which suggested the patient might have EoL concerns. These more overt solicitations were used only later in consultations, which indicates that doctors give precedence to patients volunteering EoL considerations, and offer them opportunities to take the lead in initiating EoL talk. There is evidence that doctors treat elaboration of patients' talk as a resource for engaging them in EoL conversations. However, there are limitations associated with labelling that talk as "cues" as is common in EoL communication contexts. We examine these limitations and propose "possible EoL considerations" as a descriptively more accurate term.ConclusionsThrough communicating-via open elaboration solicitations-in ways that create opportunities for patients to volunteer EoL considerations, doctors navigate a core dilemma in promoting EoL talk: giving patients opportunities to choose whether to engage in conversations about EoL whilst being sensitive to their communication needs, preferences and state of readiness for such dialogue.

Project description:BackgroundIncreasingly, consultations in health care settings are conducted remotely using a range of communication technologies. Email allows for 2-way text-based communication, occurring asynchronously. Studies have explored the content and nature of email consultations to understand the use, structure, and function of email consultations. Most previous content analyses of email consultations in primary care settings have been conducted in North America, and these have shown that concerns and assumptions about how email consultations work have not been realized. There has not been a UK-based content analysis of email consultations.ObjectiveThis study aims to explore and delineate the content of consultations conducted via email in English general practice by conducting a content analysis of email consultations between general practitioners (GPs) and patients.MethodsWe conducted a content analysis of anonymized email consultations between GPs and patients in 2 general practices in the United Kingdom. We examined the descriptive elements of the correspondence to ascertain when the emails were sent, the number of emails in an email consultation, and the nature of the content. We used a normative approach to analyze the content of the email consultations to explore the use and function of email consultation.ResultsWe obtained 100 email consultations from 85 patients, which totaled 262 individual emails. Most email users were older than 40 years, and over half of the users were male. The email consultations were mostly short and completed in a few days. Emails were mostly sent and received during the day. The emails were mostly clinical in content rather than administrative and covered a wide range of clinical presentations. There were 3 key themes to the use and function of the email consultations: the role of the GP and email consultation, the transactional nature of an email consultation, and the operationalization of an email consultation.ConclusionsMost cases where emails are used to have a consultation with a patient in general practice have a shorter consultation, are clinical in nature, and are resolved quickly. GPs approach email consultations using key elements similar to that of the face-to-face consultation; however, using email consultations has the potential to alter the role of the GP, leading them to engage in more administrative tasks than usual. Email consultations were not a replacement for face-to-face consultations.

Project description:BackgroundPeople with dementia are most at risk of experiencing serious health related suffering, if they do not have a palliative care approach introduced early enough in the illness. It can be challenging for nurses to assess experienced needs of people, who are thought no longer able to self-report such as people with dementia. Assessment help to understand the care the patient and their family need promptly. It is unknown how nurses recognise holistic palliative care needs in people with dementia during routine care.MethodsScoping review where EMBASE, MEDLINE, CINAHL, PsycInfo databases, and references were searched with an advanced search strategy, which was built on three concepts (nurses, dementia, and nursing assessment) using corresponding Medical Subject Headings. Data were charted in a piloted extraction form, based on the assessment domains within the nursing process followed by summarise and synthesise results narratively.Results37 out of 2,028 qualitative and quantitative articles published between 2000 and 2021, and relating to 2600 + nurses, were identified. Pain was sole focus of assessment in 29 articles, leaving 8 articles to describe assessment of additional needs (e.g., discomfort). Nurses working in a nursing home assess pain and other needs by observing the persons with dementia behaviour during routine care. Nurses in the acute care setting are more likely to assess symptoms with standard assessment tools at admission and evaluate symptoms by observational methods. Across settings, about one third of pain assessments are supported by person-centred pain assessment tools. Assessments were mostly triggered when the person with dementia vocalised discomfort or a change in usual behaviour was observed. Nurses rely on family members and colleagues to gain more information about needs experienced by people with dementia.ConclusionThere is a scarcity of evidence about techniques and methods used by nurses to assess needs other than pain experienced by people with dementia. A holistic, person-centred screening tool to aid real-time observations at the bedside and used in conversations with health care professionals and families/friends, may improve need recognition other than pain, to ensure holistic needs could then be addressed timely to improve care in people with dementia.
