Association of Anticholinergic Burden with Cognitive and Functional Status in a Cohort of Hospitalized Elderly: Comparison of the Anticholinergic Cognitive Burden Scale and Anticholinergic Risk Scale

Abstract Background Drugs with anticholinergic effects are associated with adverse events such as delirium and falls as well as cognitive decline and loss of independence. Objective The aim of the study was to evaluate the association between anticholinergic burden and both cognitive and functional status, according to the hypothesis that the cumulative anticholinergic burden, as measured by the Anticholinergic Cognitive Burden (ACB) Scale and Anticholinergic Risk Scale (ARS), increases the risk of cognitive decline and impairs activities of daily living. Methods This cross-sectional, prospective study (3-month telephone follow-up) was conducted in 66 Italian internal medicine and geriatric wards participating in the Registry of Polytherapies SIMI (Societa` Italiana di Medicina Interna) (REPOSI) study during 2010. The sample included 1,380 inpatients aged 65 years or older. Cognitive status was rated with the Short Blessed Test (SBT) and physical function with the Barthel Index. Each patient’s anticholinergic burden was evaluated using the ACB and ARS scores. Results The mean SBT score for patients treated with anticholinergic drugs was higher than that for patients receiving no anticholinergic medications as also indicated by the ACB scale, even after adjustment for age, sex, education, stroke and transient ischaemic attack [9.2 (95 % CI 8.6–9.9) vs. 8.5 (95 % CI 7.8–9.2); p = 0.05]. There was a dose–response relationship between total ACB score and cognitive impairment. Patients identified by the ARS had more severe cognitive and physical impairment than patients identified by the ACB scale, and the dose–response relationship between this score and ability to perform activities of daily living was clear. No correlation was found with length of hospital stay. Conclusions Drugs with anticholinergic properties identified by the ACB scale and ARS are associated with worse cognitive and functional performance in elderly patients. The ACB scale might permit a rapid identification of drugs potentially associated with cognitive impairment in a dose–response pattern, but the ARS is better at rating activities of daily living

Adherence to antibiotic treatment guidelines and outcomes in the hospitalized elderly with different types of pneumonia

Background: Few studies evaluated the clinical outcomes of Community Acquired Pneumonia (CAP), Hospital-Acquired Pneumonia (HAP) and Health Care-Associated Pneumonia (HCAP) in relation to the adherence of antibiotic treatment to the guidelines of the Infectious Diseases Society of America (IDSA) and the American Thoracic Society (ATS) in hospitalized elderly people (65 years or older). Methods: Data were obtained from REPOSI, a prospective registry held in 87 Italian internal medicine and geriatric wards. Patients with a diagnosis of pneumonia (ICD-9 480-487) or prescribed with an antibiotic for pneumonia as indication were selected. The empirical antibiotic regimen was defined to be adherent to guidelines if concordant with the treatment regimens recommended by IDSA/ATS for CAP, HAP, and HCAP. Outcomes were assessed by logistic regression models. Results: A diagnosis of pneumonia was made in 317 patients. Only 38.8% of them received an empirical antibiotic regimen that was adherent to guidelines. However, no significant association was found between adherence to guidelines and outcomes. Having HAP, older age, and higher CIRS severity index were the main factors associated with in-hospital mortality. Conclusions: The adherence to antibiotic treatment guidelines was poor, particularly for HAP and HCAP, suggesting the need for more adherence to the optimal management of antibiotics in the elderly with pneumonia

E-learning in order to improve drug prescription for hospitalized older patients : a cluster-randomized controlled study

Aims: The aim of the study was to evaluate the effect of an e-learning educational program meant to foster the quality of drug prescription in hospitalized elderly patients. Methods: Twenty geriatric and internal medicine wards were randomized to intervention (e-learning educational program) or control (basic geriatric pharmacology notions). Logistic regression analysis was used in order to assess the effect of the intervention on the use of potentially inappropriate medication (PIM, primary outcome) at hospital discharge. Secondary outcomes were a reduced prevalence of at least one potential drug\u2013drug interaction (DDI) and potentially severe DDI at discharge. Mortality rate and incidence of re-hospitalizations were other secondary outcomes assessed at the 12-month follow-up. Results: A total of 697 patients (347 in the intervention and 350 in the control arms) were enrolled. No difference in the prevalence of PIM at discharge was found between arms (OR 1.29 95%CI 0.87\u20131.91). We also found no decrease in the prevalence of DDI (OR 0.67 95%CI 0.34\u20131.28) and potentially severe DDI (OR 0.86 95%CI 0.63\u20131.15) at discharge, nor in mortality rates and incidence of re-hospitalization at 12-month follow-up. Conclusions: This e-learning educational program had no clear effect on the quality of drug prescription and clinical outcomes in hospitalized elderly patients. Given the high prevalence of PIMs and potential DDIs recorded in the frame of this study, other approaches should be developed in order to improve the quality of drug prescription in this population

Geographical differences in the prevalence of chronic polypharmacy in older people: Eleven years of the EPIFARM-Elderly project

Purpose: To compare the geographical differences in the prevalence of chronic polypharmacy in community-dwelling older people over 11 years. Methods: This study analyzed nearly two million patients aged 65-94 years recorded in the Drug Administrative Database of the Lombardy Region (Northern Italy) from 2000 to 2010. Chronic polypharmacy was defined as taking five or more drugs in 1 month for at least 6 months (consecutive or not) in a year. Results: There was a significant spatial autocorrelation that increased at the municipality level from 2000 (Moran's I Index = 0.26, z score = 16.91, p 1.96) and low (Z(G) < -1.96) prevalence rates of chronic polypharmacy were found and were not influenced by age. Chronic polypharmacy weakly correlated with hospital admission (2000: \u3c1 = 0.08, p = 0.0032; 2005: \u3c1 = 0.11, p < 0.0001; 2010: \u3c1 = 0.18, p < 0.0001), but not with mortality. Conclusions: There were geographical differences in the prevalence of older people with chronic polypharmacy that were only partly explained by health indicators. Targeted activities on prescription practice to ensure that the prescribing of chronic polypharmacy is appropriate are required

Risk factors for hospital admission of elderly patients

Background: The aim of this study was to identify which factors were associated with a risk of hospital readmission within 3 months after discharge of a sample of elderly patients admitted to internal medicine and geriatric wards. Methods: Of the 1178 patients aged 65 years or more and discharged from one of the 66 wards of the ‘Registry Politerapie SIMI (REPOSI)’ during 2010, 766 were followed up by phone interview 3 months after discharge and were included in this analysis. Univariate and multivariate logistic regression models were used to evaluate the association of several variables with rehospitalization within 3 month from discharge. Results: Nineteen percent of patients were re-admitted at least once within 3 month after discharge. By univariate analysis in-hospital clinical adverse events (AEs), a previous hospital admission, number of diagnoses and drugs, comorbidity and severity index (according to Cumulative Illness Rating Scale-CIRS), vascular and liver diseases with a level of impairment at discharge of 3 or more at CIRS were significantly associated with risk of readmission. Multivariate logistic regression analysis showed that only AEs during hospitalization, previous hospital admission, and vascular and liver diseases were significantly associated with likelihood of readmission. Conclusions: The results demonstrate the need for increased medical attention towards elderly patients discharged from hospital with characteristics such as AEs during the hospitalization, previous admission, vascular and liver diseases

Brain and kidney, victims of atrial microembolism in elderly hospitalized patients? Data from the REPOSI study.

Abstract BACKGROUND: It is well known that atrial fibrillation (AF) and chronic kidney disease (CKD) are associated with a higher risk of stroke, and new evidence links AF to cognitive impairment, independently from an overt stroke (CI). Our aim was to investigate, assuming an underlying role of atrial microembolism, the impact of CI and CKD in elderly hospitalized patients with AF. METHODS: We retrospectively analyzed the data collected on elderly patients in 66 Italian hospitals, in the frame of the REPOSI project. We analyzed the clinical characteristics of patients with AF and different degrees of CI. Multivariate logistic analysis was used to explore the relationship between variables and mortality. RESULTS: Among the 1384 patients enrolled, 321 had AF. Patients with AF were older, had worse CI and disability and higher rates of stroke, hypertension, heart failure, and CKD, and less than 50% were on anticoagulant therapy. Among patients with AF, those with worse CI and those with lower estimated glomerular filtration rate (eGFR) had a higher mortality risk (odds ratio 1.13, p=0.006). Higher disability levels, older age, higher systolic blood pressure, and higher eGFR were related to lower probability of oral anticoagulant prescription. Lower mortality rates were found in patients on oral anticoagulant therapy. CONCLUSIONS: Elderly hospitalized patients with AF are more likely affected by CI and CKD, two conditions that expose them to a higher mortality risk. Oral anticoagulant therapy, still underused and not optimally enforced, may afford protection from thromboembolic episodes that probably concur to the high mortality.

Under-detection of delirium and impact of neurocognitive de\ufb01cits on in-hospital mortality among acute geriatric and medical wards

Background: Delirium is a neuropsychiatric disorder, triggered by medical precipitants causes. Study aims were to describe the prevalence and impact on in-hospital mortality of delirium identi\ufb01ed through ICD-9 codes as well as evidence of neurocognitive de\ufb01cits demonstrated in a population of older patients admitted to acute medical wards. Methods: This was a prospective cohort multicenter study of 2521 older patients enrolled in the \u201cRegistro Politerapie SIMI (REPOSI)\u201d during the years 2010 and 2012. The diagnosis of delirium was obtained by ICD-9 codes. Cognitive function was evaluated with the Short Blessed Test (SBT) and single SBT items were used as measures of de\ufb01cits in attention, orientation and memory. Combination of de\ufb01cits in SBT items was used as a proxy for delirium. Logistic regression was used to evaluate the association with in-hospital mortality of delirium and combined de\ufb01cits in SBT items. Results: Delirium was coded in 2.9%, while de\ufb01cits in attention, orientation, and memory were found in 35.4%, 29.7%and 77.5% of patients. Inattention and either disorientation or memory de\ufb01cits were found in 14.1%, while combi-nation of the 3 de\ufb01cits in 19.8%. Delirium, as per ICD-9 codes, was not a predictor of in-hospital mortality. In contrast, objective de\ufb01cits of inattention, in combination with orientation and memory disorders, were stronger predictors after adjusting for covariates. Conclusions: The documentation of delirium is poor in medical wards of Italian acute hospitals. Neurocognitive de\ufb01cits on objective testing (in a pattern suggestive of undiagnosed delirium) should be used to raise awareness of delirium, given their association with in-hospital mortality

The stigma of low opioid prescription in the hospitalized multimorbid elderly in Italy

The primary aim of this study was to evaluate the prevalence of opioid prescriptions in hospitalized geriatric patients. Other aims were to evaluate factors associated with opioid prescription, and whether or not there was consistency between the presence of pain and prescription. Opioid prescriptions were gathered from the REgistro POliterapie Societa` Italiana di Medicina Interna (REPOSI) data for the years 2008, 2010 and 2012. 1,380 in-patients, 65+ years old, were enrolled in the first registry run, 1,332 in the second and 1,340 in the third. The prevalence of opioid prescription was calculated at hospital admission and discharge. In the third run of the registry, the degree of pain was assessed by means of a numerical scale. The prevalence of patients prescribed with opioids at admission was 3.8% in the first run, 3.6% in the second and 4.1% in the third, whereas at discharge rates were slightly higher (5.8, 5.3, and 6.6%). The most frequently prescribed agents were mild opioids such as codeine and tramadol. The number of total prescribed drugs was positively associated with opioid prescription in the three runs; in the third, dementia and a better functional status were inversely associated with opioid prescription. Finally, as many as 58% of patients with significant pain at discharge were prescribed no analgesic at all. The conservative attitude of Italian physicians to prescribe opioids in elderly patients changed very little between hospital admission and discharge through a period of 5 years. Reasons for such a low opioid prescription should be sought in physicians' and patients' concerns and prejudices
