Delirium is an acute mental state associated with poor outcomes. The incidence of delirium is high, especially in the paediatric intensive care unit (PICU). It is important for staff, particularly nurses, to understand delirium and implement interventions to prevent it. We performed a survey with the aim of evaluating and analysing the factors influencing the knowledge, attitudes and behaviour of PICU nurses towards delirium. This cross-sectional descriptive study included 215 PICU nurses in 6 PICUs from five teaching hospitals in Sichuan Province, China. An online survey about the knowledge, attitudes and practices related to delirium care was conducted among PICU nurses used a self-made and validated questionnaire. The data were analysed using descriptive statistics; differences between groups were compared using t tests, ANOVA and rank-sum tests. Variables with a significance level of 0.05 in the univariate analysis were entered into the multivariable regression analysis to identify predictors. Only 14.4% of the nurses had a good understanding of delirium, and 40.9% had received relevant training. The mean knowledge score was 9.01 ± 3.86, and the overall passing rate of knowledge was 49.8%. The mean attitude and behaviour scores were 40.95 ± 5.62 and 40.33 ± 8.01, respectively. Among the hospitals, different delirium assessments for children and specific training were performed, explaining approximately 10% of the variability in knowledge scores (F = 6.152), approximately 10% of the variability in attitude/belief scores (F = 5.908), and approximately 17% of the variability in practice scores (F = 10.767). PICU nurses have poor knowledge of delirium, particularly regarding its clinical manifestations, influencing factors and medications used, and they have adequate attitudes and confidence and good behaviour regarding delirium in children. To better prevent delirium, we suggest that PICU departments routinely assess delirium and conduct delirium training for nurses. Not applicable.
Delirium is an acute state of impaired consciousness and a medical urgency. Its broad range of alterations in mental status make diagnosis challenging. Awareness and accurate provisional diagnosis by nonpsychiatric clinicians are important for prompt management. Because delirium symptoms overlap and mimic other neuropsychiatric conditions, a referral to a consultant psychiatrist is often needed. The aim of this study was to determine the discriminating variables that are associated with concordance or discordance for a DSM-5 delirium diagnosis made by the consultation/liaison (C/L) psychiatrist as compared to the referral diagnosis/reasons given by the referring physicians for inpatients from a Tertiary Hospital in a Latin-American country. Prospective study of a cohort of 399 consecutive patients admitted to any ward of a university hospital in Medellin-Colombia and referred by a specialist physician to the C/L Psychiatry service. Analyses for diagnostic concordance used a nested sample of 140 cases diagnosed with delirium by the psychiatrist. Two multivariate logistic models were run, for delirium diagnosis concordance and discordance between the referring physician and C/L psychiatrist. The referral diagnosis was concordant with that of Psychiatry in 90/140 patients in 64.3%, with 35.7% discordance. Increasing age (OR = 1.024) and internal medicine ward (OR = 3.0) were significantly related (Wald statistic P < .05) to concordance in the multivariate analysis whose model accuracy was 68.6%. Trauma/orthopedics ward (OR = 5.7) and SARS-CoV-2 infection (OR = 3.8) were important contributors to the model fit though not significant. Accuracy of the discordance model was 70.7%, where central nervous system (CNS) disorder (OR = 6.1) and referrals from ICU (OR = 4.9), surgery (OR = 4.6), neurology/neurosurgery (OR = 5.1) and another consultant (OR = 4.7) were significantly related (Wald statistic P < .05), while metabolic/endocrine disorder (OR = 2.7) was important for model fit, but not significant. Concordance for delirium diagnosis was higher from services where education, guidelines and working relationships with C/L Psychiatry could have contributed beneficially whereas, surprisingly, CNS disorders and neurology/neurosurgery services had higher discordance, as well as the ICU. Routine use of brief sensitive delirium assessment tools such as the DDT-Pro could enhance provisional delirium diagnosis.
Delirium, a common syndrome with heterogeneous etiologies and clinical presentations, is associated with poor long-term outcomes. Recording and analyzing all delirium equally could be hindering the field's understanding of pathophysiology and identification of targeted treatments. Current delirium subtyping methods reflect clinically evident features but likely do not account for underlying biology. The Delirium Subtyping Initiative (DSI) held three sessions with an international panel of 25 experts. Meeting participants suggest further characterization of delirium features to complement the existing Diagnostic and Statistical Manual of Mental Disorders Fifth Edition Text Revision diagnostic criteria. These should span the range of delirium-spectrum syndromes and be measured consistently across studies. Clinical features should be recorded in conjunction with biospecimen collection, where feasible, in a standardized way, to determine temporal associations of biology coincident with clinical fluctuations. The DSI made recommendations spanning the breadth of delirium research including clinical features, study planning, data collection, and data analysis for characterization of candidate delirium subtypes. Delirium features must be clearly defined, standardized, and operationalized. Large datasets incorporating both clinical and biomarker variables should be analyzed together. Delirium screening should incorporate communication and reasoning.
Delivering fair and reliable summative assessments in medical education assumes examiner decision making is devoid of bias. We investigated whether candidate racial appearances influenced examiner ratings in undergraduate clinical exams. We used an internet-based design. Examiners watched a randomised set of six videos of three different white candidates and three different non-white (Asian, black and Chinese) candidates taking a clinical history at either fail, borderline or pass grades. We compared the median and interquartile range (IQR) of the paired difference between scores for the white and non-white candidates at each performance grade and tested for statistical significance. 160 Examiners participated. At the fail grade, the black and Chinese candidates scored lower than the white candidate, with median paired differences of -2.5 and -1 respectively (both p < 0.001). At the borderline grade, the black and Chinese candidates scored higher than the white candidate, with median paired differences of +2 and +3, respectively (both p < 0.001). At the passing grade, the Asian candidate scored lower than the white candidate (median paired difference -1, p < 0.001). The racial appearance of candidates appeared to influence the scores awarded by examiners, but not in a uniform manner.
Delivery of optimal, evidence-based, patient-centered care requires health care providers with not only medical knowledge and clinical skills but also statistical literacy. It is incumbent upon health professions education programs to include this critical content within the curriculum. This mixed-method explored health professions learner's attitudes toward statistics and affirms an efficacious curricular model for cultivation of statistical literacy. Through demonstration of practical and statistical significance, this model offers a practical way to integrate essential statistical methods and application within a medical curriculum. This model demonstrated success in accomplishing learner competence and received high degrees of satisfaction via student evaluations.
Dementia as a neurocognitive disorder is becoming increasingly common worldwide, and minority groups are more vulnerable than the general population. Many factors may contribute to their vulnerability such as misconceptions, language barriers, cultural factors, invalid assessment tools, lack of knowledge or assigning spiritual beliefs to dementia symptoms. Therefore, this scoping literature review aims to clarify how empirical studies reflect the meaning of dementia, language, and translation among minority ethnic groups. The PRISMA extension for the scoping review protocol was used. Thirty-eight studies published in English were reviewed and analysed. The findings revealed that lack of knowledge about dementia and attributing the disease to the normal ageing process were frequent among minority groups. Furthermore, their cultural-specific perspectives and worldviews of wellness and wellbeing can impact the way dementia is perceived, consequent help-seeking behaviours, or caregiving. Facilitating educational programs to enhance the knowledge and experiences of ethnic communities might be beneficial. Moreover, language is shown to be an important aspect in dementia assessment and participants' educational level could significantly impact their functional capacity when responding to cognitive measures. Even though there are some useful screening tests, diagnosis barriers might be eased by assessment tool development, modifications, and accurate translations for ethnic communities. A promising pathway to support ethnically diverse communities regarding dementia can be raising awareness, providing ethnic-specific services, developing cultural-specific tools to assess dementia or any cognitive impairment by considering perceptions, language, and culture among ethnic groups. Cultural and spiritual considerations could also encourage engagement during assessment.
Dementia disproportionately affects women including persons living with dementia and caregivers. Person-centered care, rather than disease-focused, is recommended to improve care for affected persons including caregivers. General practitioners play a central role in dementia care but find it challenging due to inadequate training. The study aimed to assess if and how dementia guidelines provide clinicians with guidance on person-centred care for women affected by dementia. We searched for publicly available English-language guidelines on the overall management of dementia in MEDLINE, EMBASE and the Guidelines International Network repository. We employed deductive and summative content analysis, and categorized person-centered care guideline content based on established frameworks, and conveyed our results using summary statistics, text, and tables. We reviewed 15 guidelines published from 2006 to 2020 in eight countries. Few (4, 23%) involved persons living with dementia or caregivers in guideline development. Regarding general person-centred care, guidelines mostly addressed the domains of exchange information (93%), share decisions (93%), enable self-management (93%) and address emotions (87%), while few offered content on manage uncertainty (33%) or foster a healing relationship (13%). Regarding dementia-specific person-centred care, most guidelines addressed intersectionality (tailoring care for diverse characteristics) (80%), but few included content on the domains of quality of life (67%), dignity (53%) or sex/gender issues (20%). Even when mentioned, the guidance was typically brief. We identified 32 general and 18 dementia-specific strategies to achieve person-centered care by compiling information from these guidelines. This study identified inconsistent and insufficient guideline content on person-centred care for women with dementia. Compiled strategies for achieving person-centred care could be used by developers to enhance existing and future dementia guidelines; and inform the development of policies or programs, education, tools for clinicians, and quality improvement measures for evaluating dementia care. Future research is crucial for promoting person-centred dementia care for women living with dementia.
Dementia has a long prodromal stage with various pathophysiological manifestations; however, the progression of pre-diagnostic changes remains unclear. We aimed to determine the evolutional trajectories of multiple-domain clinical assessments and health conditions up to 15 years before the diagnosis of dementia. Data was extracted from the UK-Biobank, a longitudinal cohort that recruited over 500,000 participants from March 2006 to October 2010. Each demented subject was matched with 10 healthy controls. We performed logistic regressions on 400 predictors covering a comprehensive range of clinical assessments or health conditions. Their evolutional trajectories were quantified using adjusted odds ratios (ORs) and FDR-corrected p-values under consecutive timeframes preceding the diagnosis of dementia. During a median follow-up of 13.7 [Interquartile range, IQR 12.9-14.2] years until July 2022, 7620 subjects were diagnosed with dementia. In general, upon approaching the diagnosis, demented subjects witnessed worse functional assessments and a higher prevalence of health conditions. Associations up to 15 years preceding the diagnosis comprised declined physical strength (hand grip strength, OR 0.65 [0.63-0.67]), lung dysfunction (peak expiratory flow, OR 0.78 [0.76-0.81]) and kidney dysfunction (cystatin C, OR 1.13 [1.11-1.16]), comorbidities of coronary heart disease (OR 1.78 [1.67-1.91]), stroke (OR 2.34 [2.1-1.37]), diabetes (OR 2.03 [1.89-2.18]) and a series of mental disorders. Cognitive functions in multiple tests also demonstrate decline over a decade before the diagnosis. Inadequate activity (3-5 year, overall time of activity, OR 0.82 [0.73-0.92]), drowsiness (3-5 year, sleep duration, OR 1.13 [1.04-1.24]) and weight loss (0-5 year, weight, OR 0.9 [0.83-0.98]) only exhibited associations within five years before the diagnosis. In addition, serum biomarkers of enriched endocrine, dysregulations of ketones, deficiency of brand-chain amino acids and polyunsaturated fatty acids were found in a similar prodromal time window and can be witnessed as the last pre-symptomatic conditions before the diagnosis. Our findings present a comprehensive temporal-diagnostic landscape preceding incident dementia, which could improve selection for preventive and early disease-modifying treatment trials.
Dementia is a worldwide public health concern. Implementing lifestyle changes that target modifiable risk factors is crucial for reducing the risk of dementia. The aim of this study was to investigate the effect of having family members with dementia on individuals' health beliefs and tendencies towards adopting healthier lifestyles and behaviours. A cross-sectional, comparative study was conducted with 338 people aged 40 years and older, of whom 168 have the experience of having family members with dementia, and 170 have no such experience. Data were collected using a characteristics form, the Motivation to Change Lifestyle and Health Behaviours for Dementia Risk Reduction scale, and the modified Charlson comorbidity index. Descriptive statistics, Pearson's chi-square and independent t-tests, were used. Those with family members with dementia were more likely to have greater motivation to modify their lifestyle (perceived susceptibility, severity, benefits, and cues to action) to reduce their risk of developing dementia. Additionally, they had greater perceived barriers to gain by adopting a healthy lifestyle, in contrast to those without such family members. The presence of family members with dementia could be an important factor to consider when designing initiatives targeting health beliefs related to dementia prevention behaviours and lifestyle changes.
Dementia, often misperceived as an inherent facet of aging, is, in fact, a progressive neurodegenerative condition. It carries a significant stigma due to its associated psychological and behavioral manifestations, leading to neglect and abuse within households. Studies reveal an alarming 90% treatment gap for dementia in India, largely due to limited knowledge about symptom recognition and accessing services. Thus, enhancing dementia literacy becomes crucial for early diagnosis and proper management. This study aims to assess dementia literacy and familiarity with the term "dementia" in a North Indian tertiary health-care setting. This cross-sectional study used a case vignette method among patients and their attendants at psychiatry outpatient setting in a tertiary care hospital. A validated Hindi-translated case vignette depicting a dementia patient was employed. The study gathered sociodemographic data, the case vignette, and three related questions. Participants read the vignette and provided answers. The analysis included 200 responses collected in 1 month. Respondents predominantly associated the case's condition with memory issues, mental illness, and psychosocial factors. They suggested social support, a nurturing family environment, communal living, and consulting a doctor for the protagonist. Familiarity with "dementia" was at a mere 24%. Dementia literacy and awareness of "dementia" are notably low in our sample. Urgent efforts are required to enhance dementia awareness to facilitate timely prevention, early detection, and effective management.
Democratizing genomic data science, including bioinformatics, can diversify the STEM workforce and may, in turn, bring new perspectives into the space sciences. In this respect, the development of education and research programs that bridge genome science with "place" and world-views specific to a given region are valuable for Indigenous students and educators. Through a multi-institutional collaboration, we developed an ongoing education program and model that includes Illumina and Oxford Nanopore sequencing, free bioinformatic platforms, and teacher training workshops to address our research and education goals through a place-based science education lens. High school students and researchers cultivated, sequenced, assembled, and annotated the genomes of 13 bacteria from Mars analog sites with cultural relevance, 10 of which were novel species. Students, teachers, and community members assisted with the discovery of new, potentially chemolithotrophic bacteria relevant to astrobiology. This joint education-research program also led to the discovery of species from Mars analog sites capable of producing N-acyl homoserine lactones, which are quorum-sensing molecules used in bacterial communication. Whole genome sequencing was completed in high school classrooms, and connected students to funded space research, increased research output, and provided culturally relevant, place-based science education, with participants naming three novel species described here. Students at St. Andrew's School (Honolulu, Hawai'i) proposed the name Bradyrhizobium prioritasuperba for the type strain, BL16AT, of the new species (DSM 112479T = NCTC 14602T). The nonprofit organization Kauluakalana proposed the name Brenneria ulupoensis for the type strain, K61T, of the new species (DSM 116657T = LMG = 33184T), and Hawai'i Baptist Academy students proposed the name Paraflavitalea speifideiaquila for the type strain, BL16ET, of the new species (DSM 112478T = NCTC 14603T).
Demographic ageing yields many societal consequences that depend strongly on the health status of the population. Special indicators have been developed for tracking and assessing population health, which are referred to with the overarching term healthy life expectancy (HLE). The derivation of HLE is intuitive and easily comprehensible. However, an overly simplistic interpretation hides the extreme complexity inherent in adding the health dimension to the life table. This makes HLE compared to classic life expectancy (LE) extremely sensitive to certain conceptual and methodological features. In the article, this is presented in more detail for three aspects: the underlying definition of health, the choice of survey data as a basis for estimating health status, and the reporting behavior of survey participants. It is shown that the impact on HLE can be enormous, leading to considerable bias in the interpretation of levels and trends, but also in the analysis of differences between populations. Nevertheless, the extension of classical LE to HLE is an important achievement that must not be abandoned. Therefore, the article also discusses ways in which the HLE indicator could be made more robust and reliable. Until this is achieved, however, the high methodological sensitivity of HLE must not be ignored if it is used to assess the health status of populations and as a basis for health policy measures.
Demographic and social characteristics of underrepresented groups are often poorly described in pharmacy case-based learning, leading to poor representation of these groups in the pharmacy curriculum. This research project aimed to understand the lived experience of underrepresented groups with pharmacy services and to use this to inform the development of pharmacy case-based student learning materials. This was a single centre, grounded theory, qualitative study. Focus groups were undertaken with six underrepresented groups: Māori, Pacific, Asian, LGBTQIA+ (lesbian, gay, bisexual, transgender, queer/questioning, intersex, asexual), disability, and refugee. These focus groups were conducted in Dunedin, Aotearoa New Zealand from July to August 2022. Focus group sessions were recorded and analysed to identify beliefs, ideas, and themes shared between participants and groups. Participants in all focus groups had a strong desire to be seen and represented in pharmacy cases, however this was conditional on the learning being delivered in a way that upholds their beliefs, values, and voices. From these lived experiences, cultural, environmental, personal, and social factors were identified as being critical for inclusion in pharmacy case-based learning materials. The lived experience of underrepresented populations provides critical insights that will enhance pharmacy case-based learning. The key factors that could be included in case-based learning are: ethnicity, personal beliefs, language, disability, gender identity, sexual identity, and family. To achieve health equity and improve cultural awareness and intelligence of our future pharmacy workforce, these experiences need to become more present in curricula.
