RESUMEN
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 identified through ICD-9 codes as well as evidence of neurocognitive deficits 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 "Registro Politerapie SIMI (REPOSI)" 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 deficits in attention, orientation and memory. Combination of deficits 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 deficits in SBT items. RESULTS: Delirium was coded in 2.9%, while deficits in attention, orientation, and memory were found in 35.4%, 29.7% and 77.5% of patients. Inattention and either disorientation or memory deficits were found in 14.1%, while combination of the 3 deficits in 19.8%. Delirium, as per ICD-9 codes, was not a predictor of in-hospital mortality. In contrast, objective deficits 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 deficits 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.

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.

PURPOSE: To investigate the prevalence of xanthine oxidase (XO) inhibitors prescription at admission and discharge in elderly hospital in-patients, to analyze the appropriateness of their use in relation to evidence-based indications, to evaluate the predictors of inappropriate prescription at discharge and the association with adverse events 3 months after hospital discharge. METHODS: This cross-sectional study, based upon a prospective registry, was held in 95 Italian internal medicine and geriatric hospital wards. The sample included 4035 patients aged 65 years or older at admission and 3502 at discharge. The prescription of XO inhibitors was considered appropriate in patients with diagnosis of gout, gout nephropathy, uric acid nephrolithiasis, tophi, and chemotherapy-induced hyperuricemia. In order to evaluate the predictors of inappropriate prescription of XO inhibitors, we compared the characteristics of patients considered inappropriately treated with those appropriately not treated. RESULTS: Among the 4035 patients eligible for the analysis, 467 (11.6 %) were treated with allopurinol or febuxostat at hospital admission and 461 (13.2 %) among 3502 patients discharged. At admission, 39 (8.6 %) of patients receiving XO inhibitors and 43 (9.4 %) at discharge were appropriately treated. Among those inappropriately treated, hyperuricemia, polytherapy, chronic renal failure, diabetes, obesity, ischemic cardiomyopathy, heart failure, and cardiac dysrhythmias were associated with greater prescription of XO inhibitors. Prescription of XO inhibitors was associated with a higher risk of adverse clinical events in univariate and multivariate analysis. CONCLUSIONS: Prevalence of inappropriate prescription of XO inhibitors remained almost the same at admission and discharge. Inappropriate use of these drugs is principally related to treatment of asymptomatic hyperuricemia and various cardiovascular diseases.

BACKGROUND AND PURPOSE: Women live longer and outnumber men. On the other hand, older women develop more chronic diseases and conditions such as arthritis, osteoporosis and depression, leading to a greater number of years of living with disabilities. The aim of this study was to describe whether or not there are gender differences in the demographic profile, disease distribution and outcome in a population of hospitalized elderly people. METHODS: Retrospective observational study including all patients recruited for the REPOSI study in the year 2010. Analyses are referred to the whole group and gender categorization was applied. RESULTS: A total of 1380 hospitalized elderly subjects, 50.5% women and 49.5% men, were considered. Women were older than men, more often widow and living alone or in nursing homes. Disease distribution showed that malignancy, diabetes, coronary artery disease, chronic kidney disease and chronic obstructive pulmonary disease were more frequent in men, but hypertension, osteoarthritis, anemia and depression were more frequent in women. Severity and comorbidity indexes according to the Cumulative Illness Rating Scale (CIRS-s and CIRS-c) were higher in men, while cognitive impairment evaluated by the Short Blessed Test (SBT), mood disorders by the Geriatric Depression Scale (GDS) and disability in daily life measured by Barthel Index (BI) were worse in women. In-hospital and 3-month mortality rates were higher in men. CONCLUSIONS: Our study showed a gender dimorphism in the demographic and morbidity profiles of hospitalized elderly people, emphasizing once more the need for a personalized process of healthcare.

WHAT IS KNOWN AND OBJECTIVE: Inappropriate prescribing is highly prevalent for older people and has become a global healthcare concern because of its association with negative health outcomes including ADEs, hospitalization and resource utilization. Beers' criteria are widely utilized for evaluating the appropriateness of medications, and an up-to-date version has recently been published. To assess the prevalence of patients exposed to PIMs at hospital discharge according to the 2003 and 2012 versions of Beers' criteria and to evaluate the risk of adverse clinical events, re-hospitalization and all-cause mortality at 3-month follow-up. METHODS: This cross-sectional study was held in 66 Italian internal medicine and geriatric wards. The sample included 1380 inpatients aged 65 years or older. Prescriptions of PIM were analysed at hospital discharge. We considered all patients with complete 3-month follow-up. RESULTS AND DISCUSSION: The prevalence of patients receiving at least one PIM was 20·1% and 23·5% according to the 2003 and 2012 versions of the Beers' criteria, respectively. The 2012 Beers' criteria identified more patients with at least one PIM than the 2003 version, although a high percentage of those patients (72·2%) were also identified by the criteria updated in 2003. The main difference in the prevalence of patients receiving a PIM according to the two versions of Beers' criteria involved prescriptions of benzodiazepines for insomnia or agitation, chronic use of non-benzodiazepine hypnotics, prescription of antipsychotics in people with dementia and oral iron at dosage higher than 325 mg/day. Prescription of PIMs was not associated with a higher risk of adverse clinical events, re-hospitalization and all-cause mortality at 3-month follow-up in both univariate and multivariate analysis, after adjusting for age, sex and CIRS comorbidity index. WHAT IS NEW AND CONCLUSIONS: This study found no significant effect of inappropriate drug use according to Beers' criteria on health outcomes among older adults 3 month after discharge. Even though these criteria have been suggested as helpful in promoting appropriate prescribing, reducing drug-related adverse events and associated healthcare costs, to date there is no clear evidence that their application can achieve objective and quantifiable improvements in clinical outcomes. A possible explanation is that both versions of the Beers' criteria have several recognized limitations, one of the main ones being the restricted availability of some drugs in Europe or their limited prescription in everyday clinical practice.

BACKGROUND: Poor adherence may have a major impact on clinical outcome, contributing to substantial worsening of disease, increased health care costs and even death. With increasing numbers of medications, low adherence is a growing concern, seriously undermining the benefits of current medical care. Little is known about medication adherence among older adults living at home and requiring complex medication regimens. OBJECTIVE: The aim of this study was to describe adherence to drug prescriptions in a cohort of elderly patients receiving polypharmacy, discharged from an internal medicine ward. METHODS: A sample of elderly patients (65 years of age or older) discharged from an internal medicine ward in Italy throughout 2012 were enrolled. They were followed for 3 months after discharge with a structured telephone interview to collect information on drug regimens and medication adherence 15-30 days (first follow-up) and 3 months (second follow-up) after discharge. Demographic variables including age, sex, marital status and caregiver were collected. RESULTS: Among 100 patients recruited, information on medication adherence was available for, respectively, 89 and 79 patients at the first and second follow-ups. Non-adherence was reported for 49 patients (55.1 %) at the first follow-up and for 55 (69.6 %) 3 months from discharge. Voluntary withdrawal of a drug and change of dosage without medical consultation were the main reasons for non-adherence at both follow-ups. The number of drugs prescribed at discharge was related to medication non-adherence at both follow-up interviews. No association was found between age and non-adherence. Only 25 patients (28.1 %) at the first follow-up and 20 (25.3 %) at the second understood the reasons for their medications. CONCLUSIONS: Low medication adherence is a real, complex problem for older patients receiving polypharmacy. We found that the increasing number of drugs prescribed at hospital discharge is correlated to non-adherence and a high percentage of patients did not understand the purpose of their medications. Simplification of drug regimens and reduction of pill burdens as well as better explanations of the reason for the medications should be targets for intervention.

BACKGROUND: E-learning is an efficient and cost-effective educational method. AIMS: This study aimed at evaluating the feasibility of an educational e-learning intervention, focused on teaching geriatric pharmacology and notions of comprehensive geriatric assessment, to improve drug prescribing to hospitalized elderly patients. METHODS: Eight geriatric and internal medicine wards were randomized to intervention (e-learning educational program) or control. Clinicians of the two groups had to complete a specific per group e-learning program in 30 days. Then, ten patients (aged ≥75 years) had to be consecutively enrolled collecting clinical data at hospital admission, discharge, and 3 months later. The quality of prescription was evaluated comparing the prevalence of potentially inappropriate medications through Beer's criteria and of potential drug-drug interactions through a specific computerized database. RESULTS: The study feasibility was confirmed by the high percentage (90 %) of clinicians who completed the e-learning program, the recruitment, and follow-up of all planned patients. The intervention was well accepted by all participating clinicians who judged positively (a mean score of >3 points on a scale of 5 points: 0 = useless; 5 = most useful) the specific contents, the methodology applied, the clinical relevance and utility of e-learning contents and tools for the evaluation of the appropriateness of drug prescribing. CONCLUSIONS: The pilot study met all the requested goals. The main study is currently ongoing and is planned to finish on July 2015.
