Course and Lethality of SARS-CoV2 Epidemic in Nursing Homes after Vaccination in Florence, Italy

Evidence on the effectiveness of SARS-CoV-2 vaccines in nursing home (NHs) residents is limited. We examined the impact of the BNT162b2 mRNA SARS-CoV-2 vaccine on the course of the epidemic in NHs in the Florence Health District, Italy, before and after vaccination. Moreover, we assessed survival and hospitalization by vaccination status in SARS-CoV-2-positive cases occurring during the post-vaccination period. We calculated the weekly infection rates during the pre-vaccination (1 October–26 December 2020) and post-vaccination period (27 December 2020–31 March 2021). Cox analysis was used to analyze survival by vaccination status. The study involved 3730 residents (mean age 84, 69% female). Weekly infection rates fluctuated during the pre-vaccination period (1.8%–6.5%) and dropped to zero during the post-vaccination period. Nine unvaccinated (UN), 56 partially vaccinated (PV) and 35 fully vaccinated (FV) residents tested SARS-CoV-2+ during the post-vaccination period. FV showed significantly lower hospitalization and mortality rates than PV and UV (hospitalization: FV 3%, PV 14%, UV 33%; mortality: FV 6%, PV 18%, UV 56%). The death risk was 84% and 96% lower in PV (HR 0.157, 95%CI 0.049–0.491) and FV (HR 0.037, 95%CI 0.006–0.223) versus UV. SARS-CoV-2 vaccination was followed by a marked decline in infection rates and was associated with lower morbidity and mortality among infected NH residents

"Delirium Day": A nationwide point prevalence study of delirium in older hospitalized patients using an easy standardized diagnostic tool

Background: To date, delirium prevalence in adult acute hospital populations has been estimated generally from pooled findings of single-center studies and/or among specific patient populations. Furthermore, the number of participants in these studies has not exceeded a few hundred. To overcome these limitations, we have determined, in a multicenter study, the prevalence of delirium over a single day among a large population of patients admitted to acute and rehabilitation hospital wards in Italy. Methods: This is a point prevalence study (called "Delirium Day") including 1867 older patients (aged 65 years or more) across 108 acute and 12 rehabilitation wards in Italian hospitals. Delirium was assessed on the same day in all patients using the 4AT, a validated and briefly administered tool which does not require training. We also collected data regarding motoric subtypes of delirium, functional and nutritional status, dementia, comorbidity, medications, feeding tubes, peripheral venous and urinary catheters, and physical restraints. Results: The mean sample age was 82.0 ± 7.5 years (58 % female). Overall, 429 patients (22.9 %) had delirium. Hypoactive was the commonest subtype (132/344 patients, 38.5 %), followed by mixed, hyperactive, and nonmotoric delirium. The prevalence was highest in Neurology (28.5 %) and Geriatrics (24.7 %), lowest in Rehabilitation (14.0 %), and intermediate in Orthopedic (20.6 %) and Internal Medicine wards (21.4 %). In a multivariable logistic regression, age (odds ratio [OR] 1.03, 95 % confidence interval [CI] 1.01-1.05), Activities of Daily Living dependence (OR 1.19, 95 % CI 1.12-1.27), dementia (OR 3.25, 95 % CI 2.41-4.38), malnutrition (OR 2.01, 95 % CI 1.29-3.14), and use of antipsychotics (OR 2.03, 95 % CI 1.45-2.82), feeding tubes (OR 2.51, 95 % CI 1.11-5.66), peripheral venous catheters (OR 1.41, 95 % CI 1.06-1.87), urinary catheters (OR 1.73, 95 % CI 1.30-2.29), and physical restraints (OR 1.84, 95 % CI 1.40-2.40) were associated with delirium. Admission to Neurology wards was also associated with delirium (OR 2.00, 95 % CI 1.29-3.14), while admission to other settings was not. Conclusions: Delirium occurred in more than one out of five patients in acute and rehabilitation hospital wards. Prevalence was highest in Neurology and lowest in Rehabilitation divisions. The "Delirium Day" project might become a useful method to assess delirium across hospital settings and a benchmarking platform for future surveys

Drug Prescription and Delirium in Older Inpatients: Results From the Nationwide Multicenter Italian Delirium Day 2015-2016

reserved1229noObjective: This study aimed to evaluate the association between polypharmacy and delirium, the association of specific drug categories with delirium, and the differences in drug-delirium association between medical and surgical units and according to dementia diagnosis. Methods: Data were collected during 2 waves of Delirium Day, a multicenter delirium prevalence study including patients (aged 65 years or older) admitted to acute and long-term care wards in Italy (2015-2016); in this study, only patients enrolled in acute hospital wards were selected (n = 4,133). Delirium was assessed according to score on the 4 "A's" Test. Prescriptions were classified by main drug categories; polypharmacy was defined as a prescription of drugs from 5 or more classes. Results: Of 4,133 participants, 969 (23.4%) had delirium. The general prevalence of polypharmacy was higher in patients with delirium (67.6% vs 63.0%, P =.009) but varied according to clinical settings. After adjustment for confounders, polypharmacy was associated with delirium only in patients admitted to surgical units (OR = 2.9; 95% CI, 1.4-6.1). Insulin, antibiotics, antiepileptics, antipsychotics, and atypical antidepressants were associated with delirium, whereas statins and angiotensin receptor blockers exhibited an inverse association. A stronger association was seen between typical and atypical antipsychotics and delirium in subjects free from dementia compared to individuals with dementia (typical: OR = 4.31; 95% CI, 2.94-6.31 without dementia vs OR = 1.64; 95% CI, 1.19-2.26 with dementia; atypical: OR = 5.32; 95% CI, 3.44-8.22 without dementia vs OR = 1.74; 95% CI, 1.26-2.40 with dementia). The absence of antipsychotics among the prescribed drugs was inversely associated with delirium in the whole sample and in both of the hospital settings, but only in patients without dementia. Conclusions: Polypharmacy is significantly associated with delirium only in surgical units, raising the issue of the relevance of medication review in different clinical settings. Specific drug classes are associated with delirium depending on the clinical setting and dementia diagnosis, suggesting the need to further explore this relationship.mixedAloisi Gaetano, Marengoni Alessandra, Morandi Alessandro, Zucchelli, Alberto, Cherubini Antonio, Mossello Enrico, Bo Mario, Di Santo Simona, Mazzone Andrea, Trabucchi Marco, Cappa Stefano, Fimognari Filippo, Antonelli Incalzi Raffaele, Gareri Pietro, Perticone Francesco, Campanini Mauro, Montorsi Marco, Latronico Nicola, Zambon Antonella, Bellelli Giuseppe, Rispoli Vincenzo, Malara Alba, Spadea Fausto, Di Cello Serena, Ceravolo Francesco, Fabiano Francesco, Chiaradia Giuseppe, Gabriele Amedeo, Lenino Peluso, Andrea Taristano, Settembrini Vincenzo, Capomolla Domenico, Citrino Antonella, Scriva Antonietta, Bruno Irene, Secchi Roberto, De Martino Eugenio, Muccinelli Roberto, Lupi Gerardo, Paonessa Patrizio, Fabbri Andrea, Passuti Maria Teresa, Castellari Sofia, Po Andrea, Gaggioli Guido, Varesi Massimo, Moneti Paolo, Capurso Sebastiano, Latini Vincenzo, Ghidotti Stefano, Riccardelli Francesco, Macchi Maurizio, Rigo Rosaria, Claudio Pascale, Bosio Angelo, Cerrato Flavio, Bardelli Benedetta, Boffelli Stefano, Cassinadri Angela, Franzoni Simone, Spazzini Elena, Andretto Daniela, Tonini Gabriele, Andreani Laura, Coralli Mirco, Balotta Antonio, Cancelliere Roberto, Ballardini Giorgio, Simoncelli Margherita, Mancini Annarita, Strazzacapa Mara, Fabio Stefano, De Filippi Francesco, Giudice Chiara, Dentizzi Cosimo, Azzini Margherita, Cazzadori Marco, Mastroeni Valeria, Bertassello Paolo, Santana Helena, Benati Claudia, Nesta Elisa, Tobaldini Chiara, Guerini Fabio, Tambara Elena, Mombelloni Paolo, Fontanini Fulvio, Lassa Gabriella, Lassa, Pizzorni Crosio, Oliverio Martina, del Grosso, Luciano Luca, Giavedoni Cristina, Bidoli Giuliano, Mazzei Bruno, Corsonello Andrea, Fusco Sergio, Vena Silvio, De Vuono Tommaso, Maiuri Giorgio, Fimognari Filippo Luca, Arone Andrea, Sgro Giovanni, Nicolazzo Rossella, Castegnaro Eugenio, De Rosa Salvatore, Sechi Bazzano Rossella, Benvenuti Enrico, Del Lungo Ilaria, Giardini Sante, Giulietti Chiara, Di Bari Mauro, Barghini Eleonora, Paoli Martina, Fiordelli Irene, Barucci Riccardo, Sgrilli Federica, Del Lungo Ilaria, Bertoletti Erik, D'Amico Ferdinando, Caronzolo Francesco, Grippa Alessandro, Lombardo Giuseppina, Pipicella Tiziana, Saitta Antonino, Corica Francesco, Cucinotta Valeria, Giaritta Prestipino, Larosa Daniela, Cucinotta Domenico, Basile Giorgio, March Albert, Nitti Maria Teresa, Felici Alessandro, Pavan Silvia, Piazzani Fabrizio, Lunelli Alessandra, Dimori Sergio, Margotta Alessandro, Soglia Tiziano, Postacchini Demetrio, Brunelli Roberto, Santini Silvia, Francavilla Monia, Macchiati Ilenia, Sorvillo Francesca, Giuli Cinzia, Mecocci Patrizia, Longo Annalisa, Perticone Francesco, Addesi Desiree, Rosa Paola Cerra, Bencardino Giuseppe, Falbo Tania, Grillo Nadia, Filice Marco, Mirella Filippo, Fanto Fausto, Isaia Gianluca, Pezzilli Stella, Bergamo Daniele, Furno Elisabetta, Rrodhe Sokol, Lucarini Simonetta, Dijk Babette, Dall'Acqua Francesca, Cappelletto Francesco, Calvani Donatella, Becheri Dimitri, Mottino Giuseppe, Mitidieri Costanza, Antonio Vito, Bartalucci Francesca, Magherini Lorenza, Malin Novella, Boni Franca, Gambardella Paoli Martina Lucia, Valente Carlo, Bracali Ilaria, Bracali, Foschini Alice, Bo Mario, Porrino Paola, Ceci Giacomo, Bottignole Giuliana, Tibaldi Michela, Coppo Eleonora, Ettore Evaristo, Camellini Cinzia, Servello Adriana, Grassi Alessandro, Rozzini Renzo, Tironi Sara, Grassi Maria Grazia, Troisi Elio, Caltagirone Carlo, Di Santo Simona, Franchini Flaminia, Ratto Federica, Pavoni Beatrice, Toniolo Sofia, Gabutto Anna, Quazzo Loredana, Rosatello Annalisa, Suraci Domenico, Tagliabue Benedetta, Perrone Chiara, Ferrara Lucia, Castagna Alberto, Tremolada Maria Luisa, Castoldi Giuseppe, Barbero Stefano, Oltramonti Davide, Piano Simonetta, Serviddio Gaetano, Lo Buglio Aurelio, Gurrera Tiziana, Merlo Valeria, Rovai Carla, Cotroneo Antonino Maria, Carlucci Rosaria, Abbaldo Anna, Monzani Fabio, Qasem Ahmad Amedeo, Bini Giacomo, Tafuto Silvia, Galli Giovanni, Bruni Amalia Cecilia, Mancuso Giovanna, Mancuso Gerardo, Calipari Daniela.

Delirium in nursing home residents: is there a role of antidepressants? A cross sectional study.

Background: Delirium is strongly associated with poor health outcomes, yet it is frequently underdiagnosed. Limited research on delirium has been conducted in Nursing Homes (NHs). Our aim is to assess delirium prevalence and its associated factors, in particular pharmacological prescription, in this care setting. Methods: Data from the Italian "Delirium Day" 2016 Edition, a national multicenter point-prevalence study on patients aged 65 and older were analyzed to examine the associations between the prevalence of delirium and its subtypes with demographics and information about medical history and pharmacological treatment. Delirium was assessed using the Assessment test for delirium and cognitive impairment (4AT). Motor subtype was evaluated using the Delirium Motor Subtype Scale (DMSS). Results: 955 residents, from 32 Italian NHs with a mean age of 84.72 ± 7.78 years were included. According to the 4AT, delirium was present in 260 (27.2%) NHs residents, mainly hyperactive (35.4%) or mixed subtypes (20.7%). Antidepressant treatment with selective serotonin reuptake inhibitors (SSRIs) was associated with lower delirium prevalence in univariate and multivariate analyses. Conclusions: The high prevalence of delirium in NHs highlights the need to systematically assess its occurrence in this care settings. The inverse association between SSRIs and delirium might imply a possible preventive role of this class of therapeutic agents against delirium in NHs, yet further studies are warranted to ascertain any causal relationship between SSRIs intake and reduced delirium incidence

Understanding Factors Associated With Psychomotor Subtypes of Delirium in Older Inpatients With Dementia

Objectives: Few studies have analyzed factors associated with delirium subtypes. In this study, we investigate factors associated with subtypes of delirium only in patients with dementia to provide insights on the possible prevention and treatments. Design: This is a cross-sectional study nested in the \u201cDelirium Day\u201d study, a nationwide Italian point-prevalence study. Setting and Participants: Older patients admitted to 205 acute and 92 rehabilitation hospital wards. Measures: Delirium was evaluated with the 4-AT and the motor subtypes with the Delirium Motor Subtype Scale. Dementia was defined by the presence of a documented diagnosis in the medical records and/or prescription of acetylcholinesterase inhibitors or memantine prior to admission. Results: Of the 1057 patients with dementia, 35% had delirium, with 25.6% hyperactive, 33.1% hypoactive, 34.5% mixed, and 6.7% nonmotor subtype. There were higher odds of having venous catheters in the hypoactive (OR 1.82, 95% CI 1.18-2.81) and mixed type of delirium (OR 2.23, CI 1.43-3.46), whereas higher odds of urinary catheters in the hypoactive (OR 2.91, CI 1.92-4.39), hyperactive (OR 1.99, CI 1.23-3.21), and mixed types of delirium (OR 2.05, CI 1.36-3.07). We found higher odds of antipsychotics both in the hyperactive (OR 2.87, CI 1.81-4.54) and mixed subtype (OR 1.84, CI 1.24-2.75), whereas higher odds of antibiotics was present only in the mixed subtype (OR 1.91, CI 1.26-2.87). Conclusions and Implications: In patients with dementia, the mixed delirium subtype is the most prevalent followed by the hypoactive, hyperactive, and nonmotor subtype. Motor subtypes of delirium may be triggered by clinical factors, including the use of venous and urinary catheters, and the use of antipsychotics. Future studies are necessary to provide further insights on the possible pathophysiology of delirium in patients with dementia and to address the optimization of the management of potential risk factors

Drug Prescription and Delirium in Older Inpatients: Results From the Nationwide Multicenter Italian Delirium Day 2015-2016

Objective: This study aimed to evaluate the association between polypharmacy and delirium, the association of specific drug categories with delirium, and the differences in drug-delirium association between medical and surgical units and according to dementia diagnosis. Methods: Data were collected during 2 waves of Delirium Day, a multicenter delirium prevalence study including patients (aged 65 years or older) admitted to acute and long-term care wards in Italy (2015-2016); in this study, only patients enrolled in acute hospital wards were selected (n = 4,133). Delirium was assessed according to score on the 4 "A's" Test. Prescriptions were classified by main drug categories; polypharmacy was defined as a prescription of drugs from 5 or more classes. Results: Of 4,133 participants, 969 (23.4%) had delirium. The general prevalence of polypharmacy was higher in patients with delirium (67.6% vs 63.0%, P =.009) but varied according to clinical settings. After adjustment for confounders, polypharmacy was associated with delirium only in patients admitted to surgical units (OR = 2.9; 95% CI, 1.4-6.1). Insulin, antibiotics, antiepileptics, antipsychotics, and atypical antidepressants were associated with delirium, whereas statins and angiotensin receptor blockers exhibited an inverse association. A stronger association was seen between typical and atypical antipsychotics and delirium in subjects free from dementia compared to individuals with dementia (typical: OR = 4.31; 95% CI, 2.94-6.31 without dementia vs OR = 1.64; 95% CI, 1.19-2.26 with dementia; atypical: OR = 5.32; 95% CI, 3.44-8.22 without dementia vs OR = 1.74; 95% CI, 1.26-2.40 with dementia). The absence of antipsychotics among the prescribed drugs was inversely associated with delirium in the whole sample and in both of the hospital settings, but only in patients without dementia. Conclusions: Polypharmacy is significantly associated with delirium only in surgical units, raising the issue of the relevance of medication review in different clinical settings. Specific drug classes are associated with delirium depending on the clinical setting and dementia diagnosis, suggesting the need to further explore this relationship
