This study assessed Australian clinical practice guidelines for life-limiting index conditions for the extent to which they acknowledged comorbidities and framed management recommendations within the context of older age and reduced life expectancy. A comprehensive search identified current, evidence-based Australian guidelines for chronic life-limiting conditions directed at general practitioners. Guideline content was analysed qualitatively before comorbidity acknowledgements were quantified using a 17-item checklist. Full guidelines were quality appraised using AGREE-II. Ten documents covering chronic obstructive pulmonary disease, heart failure, cancer pain, dementia and palliative care in aged care were identified. Most guidelines addressed one 'comorbid' condition and prompted clinicians to consider patient quality of life and personal preferences. Fewer addressed burden of treatment and half suggested modifying treatments to account for limited life expectancy, age or time horizon to benefit. Half warned of potential adverse drug interactions. Guidelines were of moderate to very high quality. Guidelines naturally prioritised their index condition, directing attention to only the most common comorbidities. However, there may be scope to include more condition-agnostic guidance on multimorbidity management. This might be modelled on the 'guiding principles' approach now emerging internationally from organisations such as the American Geriatrics Society in response to increasing multimorbidity prevalence and evidence limitations.

This might be modelled on the 'guiding principles' approach now emerging internationally from organisations such as the American Geriatrics Society in response to increasing multimorbidity prevalence and evidence limitations. General practitioners provide frontline care for a growing number of patients with multimorbidity, which may involve a life-limiting, progressive condition. Most guidelines for life-limiting conditions acknowledge comorbidity; however, there may be missed opportunities to warn clinicians on the potential for inappropriate polypharmacy, drug–drug interactions, and guideline-imposed treatment burden. Guidelines might consider incorporating 'guiding principles' of multimorbidity care and reframing management in the context of reduced life expectancy. [ABSTRACT FROM AUTHOR]

Background: Searching for topics within large biomedical databases can be challenging, especially when topics are complex, diffuse, emerging or lack definitional clarity. Experimentally derived topic search filters offer a reliable solution to effective retrieval; however, their number and range of subject foci remain unknown. Objectives: This systematic scoping review aims to identify and describe available experimentally developed topic search filters. Methods: Reports on topic search filter development (1990‐) were sought using grey literature sources and 15 databases. Reports describing the conception and prospective development of a database‐specific topic search and including an objectively measured estimate of its performance ('sensitivity') were included. Results: Fifty‐four reports met inclusion criteria. Data were extracted and thematically synthesised to describe the characteristics of 58 topic search filters. Discussion: Topic search filters are proliferating and cover a wide range of subjects. Filter reports, however, often lack clear definitions of concepts and topic scope to guide users. Without standardised terminology, filters are challenging to find. Information specialists may benefit from a centralised topic filter repository and appraisal checklists to facilitate quality assessment. Conclusion: Findings will help information specialists identify existing topic search filters and assist filter developers to build on current knowledge in the field. [ABSTRACT FROM AUTHOR]

Objectives Health professionals must be able to search competently for evidence to support practice. We sought to understand how palliative care clinicians construct searches for palliative care literature in PubMed, to quantify search efficacy in retrieving a set of relevant articles and to compare performance against a Palliative CareSearch Filter ( PCSF). Methods Included studies from palliative care systematic reviews formed a test set. Palliative care clinicians ( n = 37) completed a search task using PubMed. Individual clinician searches were reconstructed in PubMed and combined with the test set to calculate retrieval sensitivity. PCSF performance in the test set was also determined. Results Many clinicians struggled to create useful searches. Twelve used a single search term, 17 narrowed the search inappropriately and 8 confused Boolean operators. The mean number of test set citations ( n = 663) retrieved was 166 ( SD = 188), or 25% although 76% of clinicians believed they would find more than 50% of the articles. Only 8 participants (22%) achieved this. Correlations between retrieval and PubMed confidence (r = 0.13) or frequency of use ( r = −0.18) were weak. Conclusions Many palliative care clinicians search PubMed ineffectively. Targeted skills training and PCSF promotion may improve evidence retrieval. [ABSTRACT FROM AUTHOR]

Objective. To develop and validate a PubMed search filter, LIt.search, that automatically retrieves Aboriginal and Torres Strait Islander health literature and to make it publicly accessible through the Lowitja Institute website. Methods. Search filter development phases included: (1) scoping of the publication characteristics of Aboriginal and Torres Start Islander literature; (2) advisory group input and review; (3) systematic identification and testing of MeSH and text word terms; (4) relevance assessment of the search filter's retrieved items; and (5) translation for use in PubMed through the web. Results. Scoping study analyses demonstrated complexity in the nature and use of possible search terms and publication characteristics. The search filter achieved a recall rate of 84.8% in the full gold standard test set. To determine real-world performance, post-hoc assessment of items retrieved by the search filter in PubMed was undertaken with 87.2% of articles deemed as relevant. The search filter was constructed as a series of URL hyperlinks to enable one-click searching. Conclusion. LIt.search is a search tool that facilitates research into practice for improving outcomes in Aboriginal and Torres Strait Islander health and is publicly available on the Lowitja Institute website.

One approach to manage people with behaviours of concern including agitated or aggressive behaviours in health care settings is through the use of fast‐acting medication, called chemical restraint. Such management often needs to be delivered in crisis situations to patients who are at risk of harm to themselves or others. This paper summarizes the available evidence on the effectiveness and safety of chemical restraint from 21 randomized controlled trials (RCTs) involving 3788 patients. The RCTs were of moderate to high quality and were conducted in pre‐hospital, hospital emergency department, or ward settings. Drugs used in chemical restraint included olanzapine, haloperidol, droperidol, risperidol, flunitrazepam, midazolam, promethazine, ziprasidone, sodium valproate, or lorazepam. There was limited comparability between studies in drug choice, combination, dose, method of administration (oral, intramuscular, or intravenous drip), or timing of repeat administrations. There were 31 outcome measures, which were inconsistently reported. They included subjective measures of behaviours, direct measures of treatment effect (time to calm; time to sleep), indirect measures of agitation (staff or patient injuries, duration of agitative or aggressive episodes, subsequent violent episodes), and adverse events. The most common were time to calm and adverse events. There was little clarity about the superiority of any chemical method of managing behaviours of concern exhibited by patients in Emergency Departments or acute mental health settings. Not only is more targeted research essential, but best practice recommendations for such situations requires integrating expert input into the current evidence base. [ABSTRACT FROM AUTHOR]

Background: Reports from patients on seeing or hearing a dead relative or dreaming a highly significant dream at the end of life can be perplexing for health professionals who may wonder how best to respond. Aim: The aim of this study was to systematically review the literature on deathbed phenomena (DBP), and provide suggestions for a clinical response to dying patients’ recounts of these hard-to-explain phenomena. Methods: The authors searched for relevant studies which reported on DBP within a palliative care context. Eligibility criteria were established, a review process was employed and a narrative synthesis approach was used to interpret the data. Results: In total, eight papers met the inclusion criteria. Reported prevalence of DBP ranged from 24–51% with common themes described. Distinguishing between DBP and hallucinations was discussed, requiring very different clinical responses. Phenomena were timed most often in the last hours or days before death. Experiencing a DBP was, in most cases, deeply meaningful, bringing comfort, peace and reassurance. Health professionals were not surprised to hear of a DBP, but were not always well prepared to respond appropriately. Conclusions: Rather than simply dismissing DBP as medication related or the physiological effects of dying, the significance of these events and the comfort afforded by them to patients and carers should be recognised. Disclosure of DBP may enable health professionals to discuss more spiritual and existential concerns, which have the potential to offer hope, meaning and connection. We propose strategies and approaches for strengthening compassionate clinical practice in this area. [ABSTRACT FROM AUTHOR]

Background The evidence base developed by, and relevant to, primary health care (PHC) is rapidly increasing. With the wealth of literature available, searchers trying to find PHC-specific citations can feel overwhelmed. Objectives Flinders Filters and the Primary Health Care Research & Information Service collaborated to develop a search filter enabling efficient and effective retrieval of relevant PHC literature. Methods Stage 1 involved developing a PHC Search Filter in the OvidSP Medline platform using a rigorous experimental methodology. The search filter was then translated for Web-based 'one-click searching' in PubMed during Stage 2. Stage 3 involved planning and implementing a mixed-methods evaluation. Results The search filter sensitivity was 77.0% with a post hoc relevance assessment of 78.3%. Four months after its launch, a mixed-methods study evaluated the PHC Search Filter. With 90 respondents, analysis of data from the online survey demonstrated overarching benefits, a positive response to the tool and directions for further refinement of the PHC Search Filter. Discussion Designing the PHC Search Filter followed an established method that ensures the tool offers a validated search strategy. Evaluation results suggest that the PHC Search Filter is a useful tool that is easy to navigate. Challenges for the Filter relate to access to full text articles, while challenges for the evaluation relate to the small sample size. Conclusions The PHC Search Filter reduces the burden associated with literature searching, increases the value of the results that are received and provides a useful resource to improve the likelihood of incorporating relevant evidence into policy and practice.
