Validation of the O3DY French Version (O3DY-F) for the Screening of Cognitive Impairment in Community Seniors in the Emergency Department.

BACKGROUND: It is recommended that older patients undergo systematic mental status screening when presenting to the emergency department (ED). However, the tools available are not necessarily adapted to the ED environment, therefore, quicker and easier tools are needed. OBJECTIVES: The purpose of this study is to validate the Ottawa 3DY-French (O3DY-F) Scale as a screening tool for delirium and cognitive impairment in a French-speaking cohort. METHOD: This multicenter prospective study was conducted in four hospitals across the province of Quebec. Inclusion criteria were: age ≥ 65 years, ED stay ≥ 8 h, awaiting admission to a care unit, and independent or semi-independent in their daily living activities. Cognitive status was assessed during the initial interview using the Telephone Interview for Cognitive Screening-modified (TICS-m) and the O3DY-F scale. Comparisons were made between the O3DY-F and the TICS-m and Confusion Assessment Method (CAM) to assess the sensitivity and specificity of the O3DY-F for the detection of cognitive impairment and delirium. RESULTS: A total of 313 patients were included in this study, 139 of which had a positive O3DY-F. When compared with the CAM, the O3DY-F had a sensitivity of 84.2% (95% confidence interval [CI] 60.4-96.6) and a specificity of 58.2% (95% CI 52.3-63.9) for the detection of prevalent delirium. The O3DY-F had a sensitivity of 76.2% (95% CI 66.7-84.8) and a specificity of 67.6% (95% CI 61.0-73.6) for cognitive impairment (defined as a TICS-m < 27). CONCLUSION: The O3DY-F is a useful and effective tool to screen for delirium and undetected cognitive impairment among a French-speaking cohort in the ED.

Survey on Current Practice of Canadian Physicians Regarding the Investigation in Older Patients with Delirium.

Background: The current literature provides heterogeneous recommendation regarding the investigation of older delirious patients, which may lead to over-testing. Our study aims to describe Canadian physicians' current practice for the investigation of older patients with delirium. Our secondary objective is to define specific indications for performing a CT head scan in this population. Methods: Design: cross-sectional online survey. Participants: physicians who conduct their clinical practice in Canada and who care for older patients with delirium. Potential study participants were reached through Canadian associations: Canadian Geriatrics Society, the Canadian Association of Emergency Physicians, the Association des Médecins d'Urgence du Québec, and members of Choosing Wisely Canada. Results: We received 296 survey responses. More than 80% of respondents always order complete blood count, urea, and creatinine and electrolytes. Extended electrolytes, TSH, chest X-ray, electrocardiogram, urinalysis and urinary culture tests tend to be ordered somewhat frequently. Physicians mostly agreed to order a head CT scan for loss of consciousness, altered mental status, fall, and anticoagulation. Conclusions: Physicians' investigations for older patients with delirium are highly variable, even with the lack of evidence supporting a broad workup. Also, respondents mostly align with current recommendations of indications for CT head scans.

Investigation and treatment of asymptomatic bacteriuria in older patients with delirium: a cross-sectional survey of Canadian physicians.

OBJECTIVES: Current guidelines suggest assessing non-infectious causes and careful observation before giving antibiotics to delirious patients with asymptomatic bacteriuria. Our study aims to describe the current practice of Canadian physicians regarding the investigation and treatment of asymptomatic bacteriuria in delirious older patients (aged ≥ 65 years). METHODS: Our team of medical experts designed and reviewed a cross-sectional online survey. Study participants were physicians who conduct their clinical practice in Canada and care for older patients with delirium in their current practice. Potential study participants were reached through Canadian associations: Canadian Geriatrics Society, the Canadian Association of Emergency Physicians, the Association des Médecins d'Urgence du Québec and members of Choosing Wisely Canada. RESULTS: 297 physicians were included. The main results show 79.4% of our participants request a urine dipstick or urinalysis in delirious patients and 52.4% immediately order a urine culture with the urinalysis. If bacteriuria is found in delirious but afebrile patients without urinary symptoms, 38% of physicians immediately treat with antibiotics, 33.8% wait for culture before initiating treatment, 14.4% treat if no other cause is found for delirium and only 13.7% would refrain from giving antibiotics. Results from respondents were similar for delirious patients with known cognitive impairment. Participants were almost unanimous (92.5%) in saying they need clear guidelines regarding the treatment of bacteriuria in older delirious patients. CONCLUSIONS: This survey highlights the heterogeneous clinical management of asymptomatic bacteriuria in delirious patients and the need for clear guidelines for patients.

RéSUMé: OBJECTIFS: Les directives actuelles suggèrent d'évaluer les causes non infectieuses et de procéder à une observation attentive avant d'administrer des antibiotiques aux patients délirants présentant une bactériurie asymptomatique. Notre étude vise à décrire la pratique actuelle des médecins canadiens concernant l'investigation et le traitement de la bactériurie asymptomatique chez les patients âgés délirants (âgés ≥ 65 ans). MéTHODES: Notre équipe d'experts médicaux a conçu et examiné une enquête transversale en ligne. Les participants à l'étude étaient des médecins qui exercent leur pratique clinique au Canada et qui soignent des patients âgés atteints de délire dans leur pratique actuelle. Les participants potentiels à l'étude ont été contactés par le biais d'associations canadiennes: Société Canadienne de Gériatrie, l'Association Canadienne des Médecins d'Urgence, l'Association des Médecins d'Urgence du Québec et les membres de Choisir avec soin (Choosing Wisely Canada). RéSULTATS: 297 médecins ont été inclus. Les principaux résultats montrent que 79,4% de nos participants demandent une bandelette urinaire ou une analyse d'urine chez les patients délirants et 52,4% demandent immédiatement une culture d'urine avec l'analyse d'urine. En cas de découverte d'une bactériurie chez des patients délirants mais afébrile sans symptômes urinaires, 38% des médecins traitent immédiatement avec des antibiotiques, 33,8% attendent la culture avant de commencer le traitement, 14,4% traitent si aucune autre cause n'est trouvée pour le délire et seulement 13,7% s'abstiendraient de donner des antibiotiques. Les résultats des répondants étaient semblables chez les patients délirants ayant une déficience cognitive connue. Les participants étaient presque unanimes (92,5%) à dire qu'ils avaient besoin de lignes directrices claires concernant le traitement de la bactériurie chez les patients délirants plus âgés. CONCLUSIONS: Cette étude met en évidence la prise en charge clinique hétérogène de la bactériurie asymptomatique chez les patients délirants et la nécessité de lignes directrices claires pour les patients.

Potential benefits of incentive spirometry following a rib fracture: a propensity score analysis.

CLINICIAN'S CAPSULEWhat is known about the topic?Literature regarding the impact of incentive spirometry on patients with rib fractures is unclear; there are no recommendations for its use in the emergency department (ED).What did this study ask?The objective of this study was to assess the impact of incentive spirometry on delayed complications in patients with rib fractures in the ED.What did this study find?Unsupervised incentive spirometry use does not have a protective effect against delayed pulmonary complications after a rib fracture.Why does this study matter to clinicians?Clear guidelines for incentive spirometry use for patients with rib fractures and further research to assess its usefulness in other ED populations are needed.

OBJECTIFS: La spirométrie incitative est parfois prescrite en vue d'encourager le rétablissement de la fonction respiratoire. Toutefois, peut de littérature est disponible sur la spirométrie incitative et ses effets chez les patients avec fracture de côtes, et il n'existe pas de recommandation sur son utilisation au département des urgences (DU), tout particulièrement pour les fractures de côtes, qui sont reconnues pour accroître le risque de complications pulmonaires. Cette étude visait donc à évaluer l'utilisation de la spirométrie incitative et à mesurer son impact sur l'incidence de complications tardives chez les patients ayant été libéré de l'urgence après une confirmation de fracture de côtes. MÉTHODE: Il s'agit d'une sous-étude planifiée d'une étude observationnelle de cohorte prospective, qui a eu lieu dans 4 DU au Canada, entre novembre 2006 et mai 2012. Des patients âgés de 16 ans et plus, non hospitalisés, avec au moins une fracture de côte confirmée par radiographie ont été sélectionnés. La décision de prescrire la spirométrie incitative était laissée à la discrétion du médecin traitant. Les principaux résultats consistaient en l'apparition d'une pneumonie, d'atélectasie ou d'un hémothorax dans les 14 jours suivant le traumatisme. Des analyses d'appariement des coefficients de propension ont été réalisées. RÉSULTATS: Un total de 439 patients ont participé à l'étude, dont 182 (41,5%) ont été reçu la spirométrie incitative. 99 cas d'hémothorax (22,6%), 103 cas d'atélectasie (23,5%) et 4 cas de pneumonie (0,9%) ont été observés. Nos résultats indiquent que la spirométrie incitative ne semble pas un moyen de protection contre l'hémothorax (risque relatif [RR] = 1,03 [0,66­1,64]) ni contre l'atélectasie ou la pneumonie (RR = 1,07 [0,68­1,72]). CONCLUSION: Nos résultats suggèrent que la spirométrie incitative non supervisée n'offrirait pas d'effet protecteur contre l'apparition tardive de complications pulmonaires à la suite d'une fracture de côtes. D'autres recherches sont nécessaires afin de valider la pertinence de prescrire la spirométrie incitative au DU, chez certains groupes de blessés plus spécifiques.

Using the Bergman-Paris Question to screen seniors in the emergency department.

OBJECTIVES: In the fast pace of the Emergency Department (ED), clinicians are in need of tailored screening tools to detect seniors who are at risk of adverse outcomes. We aimed to explore the usefulness of the Bergman-Paris Question (BPQ) to expose potential undetected geriatric syndromes in community-living seniors presenting to the ED. METHODS: This is a planned sub-study of the INDEED multicentre prospective cohort study, including independent or semi-independent seniors (≥65 years old) admitted to hospital after an ED stay ≥8 hours and who were not delirious. Patients were assessed using validated screening tests for 3 geriatric syndromes: cognitive and functional impairment, and frailty. The BPQ was asked upon availability of a relative at enrolment. BPQ's sensitivity and specificity analyses were used to ascertain outcomes. RESULTS: A response to the BPQ was available for 171 patients (47% of the main study's cohort). Of this number, 75.4% were positive (suggesting impairment), and 24.6% were negative. To detect one of the three geriatric syndromes, the BPQ had a sensitivity of 85.4% (95% CI [76.3, 92.0]) and a specificity of 35.4% (95% CI [25.1, 46.7]). Similar results were obtained for each separate outcome. Odds ratio demonstrated a higher risk of presence of geriatric syndromes. CONCLUSION: The Bergman-Paris Question could be an ED screening tool for possible geriatric syndrome. A positive BPQ should prompt the need of further investigations and a negative BPQ possibly warrants no further action. More research is needed to validate the usefulness of the BPQ for day-to-day geriatric screening by ED professionals or geriatricians.

Performance of the French version of the 4AT for screening the elderly for delirium in the emergency department.

OBJECTIVES: Delirium is very frequent in older patients presenting to the emergency department (ED), but is often undetected. The purpose of this study was to evaluate the performance of the French version of the 4 A's Test (4AT-F) for the detection of delirium and cognitive impairment in older patients. METHODS: The study was conducted in four Canadian ED. Participants (n= 320) were independent or semi-independent patients (able to perform ≥5 activities of daily living) aged 65 and older and had an 8-hour exposure to the ED environment. The Telephone Interview for Cognitive Status (TICS-m), the Confusion Assessment Method (CAM) as well as the 4AT-F were administered to patients at the initial interview. The CAM and 4AT-F were then administered twice a day during the patients' ED or hospital stay. The 4AT-F's sensitivity and specificity were compared to those of the CAM (for delirium), and to that of the TICS (for cognitive impairment). RESULTS: Our results suggest that the 4AT-F has a sensitivity of 84% (95% CI: [76, 93]) and a specificity of 74% (95% CI: [70, 78]) for delirium, as well as a sensitivity of 49% (95% CI: [34, 64]) and a specificity of 87% (95% CI: [82, 92]) for cognitive impairment. CONCLUSION: The 4AT-F is a fast and reliable screening tool for delirium and cognitive impairment in ED. Due to its quick administration time, it allows a systematic screening of patients at risk of delirium, without significantly increasing the workload of the ED staff.
