Spesa sanitaria e invecchiamento della popolazione: il ruolo delle patologie croniche

La letteratura individua diverse cause per l’aumento della spesa sanitaria e fra queste, nei paesi dell’Occidente, l’invecchiamento della popolazione è certamente uno dei fattori principali, soprattutto dove l’indice di vecchiaia si associa anche ad indice di dipendenza sempre più elevato. Occorre tuttavia notare che non tutta la letteratura è d’accordo circa il vero effetto che l’invecchiamento ha sulla spesa, soprattutto se consideriamo solo quella sanitaria in senso stretto, escludendo le spese che derivano dalla long term care. Un secondo motivo importante di aumento della spesa sanitaria è certamente correlato alle malattie croniche. In questo lavoro, partendo dai dati contenuti negli archivi informatici utilizzati dall’Asl di Brescia per motivi gestionali-amministrativi ci proponiamo di studiare il fenomeno della spesa nella popolazione anziana cercando di distinguere, per quanto possibile, il costo che deriva dal semplice aumento dell’età da quello che può essere attribuito all’aggravarsi della patologia cronica. Sebbene infatti i due fenomeni siano fra loro strettamente legati, le implicazioni dal punto di vista di policy sono molto diverse: mentre l’invecchiamento della popolazione è in qualche modo un fattore inevitabile sul quale la Asl e l’intero Ssn non possono agire, la malattia cronica può in qualche modo essere, se non prevenuta, almeno posticipata e/o arginata nelle sue complicanze

Enhanced CAMx source apportionment analysis at an urban receptor in Milan based on source categories and emission regions

Source apportionment results from CAMx/PSAT v6.3 model simulation at an urban receptor placed in Milan city centre are presented. CAMx was run over a domain covering the Po valley for the calendar year of 2010. Model simulations considered nitrogen dioxide (NO2), fine particulate matter (PM2.5), and its primary and secondary components, i.e.: elemental carbon (EC) and nitrate (NO3−). Source apportionment results are separately reported with respect to emission regions (e.g.: local, urban, metropolitan areas, counties) and emission categories (e.g.: transport, space heating, industrial activities) and to the combination of emission regions and categories. Five emission regions were considered, starting from a narrow region covering Milan city centre, up to Milan municipality, Milan metropolitan area, Lombardy region, and to the entire Po valley. In terms of emission region contributions, Milan municipality, its metropolitan area, and Lombardy region account for about 60% of PM2.5 total mass at the selected receptor. However, local scale emissions contribute for more than 50% to EC ambient levels at this receptor. Conversely, the sources located in the farthest emission regions (Lombardy and Po valley) and long range transport determine the largest contribution (80%) to NO3− concentration. For NO2, local scale emissions are responsible for more than 60% of the ambient concentration levels in Milan city centre. In terms of source categories, traffic is the main contributor to NO2 and NO3−, biomass burning and traffic to EC and PM2.5 mass. The emission categories contributions to PM2.5 estimated by CAMx/PSAT for the selected receptor show a rather good agreement with Positive Matrix Factorization (PMF) source apportionment results available for Milan area. However, the two approaches provide similar estimations only for biomass burning and traffic contributions (24% and 20%, respectively) whereas CAMx gives remarkably lower estimates for the share of secondary organic aerosol (SOA), likely because of missing formation processes in CAMx chemical module. © 2019 The Author(s)This work has been financed by the Research Fund for the Italian Electrical System under the Contract Agreement between RSE S.p.A. and the Ministry of Economic Development - General Directorate for Nuclear Energy , Renewable Energy and Energy Efficiency in compliance with the Decree of March 8, 2006.

Hospital Care of Older Patients With COPD: Adherence to International Guidelines for Use of Inhaled Bronchodilators and Corticosteroids

313noObjectives: We aimed to analyze the prevalence and impact of COPD in older patients hospitalized in internal medicine or geriatric wards, and to investigate adherence to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, associated clinical factors, and outcomes. Design: Data were obtained from REgistro POliterapie SIMI (REPOSI), a prospective multicenter observational registry that enrolls inpatients aged 65 years. Setting and Participants: Older hospitalized patients enrolled from 2008 to 2016 with a diagnosis of COPD. Measures: We evaluated adherence to the 2018 GOLD guidelines at admission and discharge, by examining the prescription of inhaled bronchodilators and corticosteroids in COPD patients. We also evaluated the occurrence of outcomes and its association with COPD and guideline adherence. Results: At hospital admission, COPD was diagnosed in 1302 (21.5%) of 6046 registered patients. COPD patients were older, with more impaired clinical and functional status and multiple comorbidities. Overall, 34.3% of COPD patients at admission and 35.6% at discharge were adherent to the GOLD guidelines. Polypharmacy (5 drugs) at admission [odds ratio (OR): 3.28, 95% confidence interval (CI): 2.24-4.81], a history of acute COPD exacerbation (OR: 2.65, 95% CI: 1.44-4.88) at admission, smoking habit (OR: 1.45, 95% CI: 1.08-1.94), and polypharmacy at discharge (OR: 6.76, 95% CI: 4.15-11.0) were associated with adherence to guidelines. COPD was independently associated with the risk of cardiovascular and respiratory death and rehospitalization occurrence compared to patients without COPD during follow-up. Adherence to guidelines was inversely associated with the occurrence of death from all causes (OR: 0.12, 95% CI: 0.02-0.90). Conclusions/Implications: COPD was common in older patients acutely hospitalized, showing an impaired functional and clinical status. Prescriptions for older COPD patients were often not adherent to GOLD guidelines. Poor adherence to guidelines was associated with a worse clinical status. There is a need to improve adherence to guidelines in treating COPD patients, with the ultimate goal of reducing clinical events.reservedmixedProietti, Marco; Agosti, Pasquale; Lonati, Chiara; Corrao, Salvatore;

Antibiotic use and associated factors in a large sample of hospitalised older people.

OBJECTIVES: The aims of this study were to assess (i) the prevalence of antibiotic use, (ii) factors associated with their use and (iii) the association with in-hospital mortality in a large sample of hospitalised older people in Italy. METHODS: Data were obtained from the 2010-2017 REPOSI register held in more than 100 internal medicine and geriatric wards in Italy. Patients aged ≥65 years with at least one antibiotic prescription during their hospitalisation were selected. Multivariable logistic regression models were used to determine factors associated with antibiotic use. RESULTS: A total of 5442 older patients were included in the analysis, of whom 2786 (51.2%) were prescribed antibiotics during their hospitalisation. The most frequently prescribed antibiotic class was β- lactams, accounting for 50% of the total prescriptions. Poor physical independence, corticosteroid use and being hospitalised in Northern Italy were factors associated with a higher likelihood of being prescribed antibiotics. Antibiotic use was associated with an increased risk of in-hospital mortality (odds ratio=2.52, 95% confidence interval 1.82-3.48) also when accounting for factors associated with their use. CONCLUSION: Hospitalised older people are often prescribed antibiotics. Factors related to poor physical independence and corticosteroid use are associated with increased antibiotic use. Being prescribed antibiotics is also associated with an increased risk of in-hospital death. These results demand the implementation of specific stewardship programmes to improve the correct use of antibiotics in hospital settings and to reduce the risk of antimicrobial resistance

Drug–drug interactions involving CYP3A4 and p-glycoprotein in hospitalized elderly patients

Polypharmacy is very common in older patients and may be associated with drug-drug interactions. Hepatic cytochrome P450 (notably 3A4 subtype, CYP3A4) is a key enzyme which metabolizes most drugs; P-glycoprotein (P-gp) is a transporter which significantly influences distribution and bioavailability of many drugs. In this study, we assess the prevalence and patterns of potential interactions observed in an hospitalized older cohort (Registro Politerapia Societa Italiana di Medicina Interna) exposed to at least two interacting drugs involving CYP3A4 and P-gp at admission, during hospitalization and at discharge. Individuals aged 65 and older (N-4039; mean age 79.2; male 48.1%), hospitalized between 2010 and 2016, were selected. The most common combinations of interacting drugs (relative frequency > 5%) and socio-demographic and clinical factors associated with the interactions were reported. The prevalence of interactions for CYP3A4 was 7.9% on admission, 10.3% during the stay and 10.7% at discharge; the corresponding figures for P-gp interactions were 2.2%, 3.8% and 3.8%. The most frequent interactions were amiodarone-statin for CYP3A4 and atorvastatin-verapamil-diltiazem for P-gp. The prevalence of some interactions, mainly those involving cardiovascular drugs, decreased at discharge, whereas that of others, e.g. those involving neuropsychiatric drugs, increased. The strongest factor associated with interactions was polypharmacy (OR 6.7, 95% CI 5.0-9.2). In conclusion, hospital admission is associated with an increased prevalence, but also a changing pattern of interactions concerning CYP3A4 and P-gp in elderly. Educational strategies and appropriate use of dedicated software seem desirable to limit drug interactions and the inherent risk of adverse events in older patients

Inappropriate prescription of benzodiazepines in acutely hospitalized older patients.

Benzodiazepines (BDZs) are widely prescribed in older people. The aims of the study are to assess the prevalence of inappropriate prescription of BZDs and the associated factors in acutely hospitalized older patients. Patients aged 65 years or more hospitalized from 2010 to 2017 in more than 100 Italian internal medicine and geriatric wards in the frame of the REPOSI register were included if prescribed with BDZs at hospital admission or discharge. Appropriateness of prescription was assessed according to the 2015 Beers criteria and their modified French and German versions. Among 4681 patients discharged from hospital, 15% (N = 710) were discharged with BDZs, and 62% of them (N = 441, 95% CI: 58.5%-65.6%) were inappropriately prescribed, being prescribed with BDZ to be always avoided in the elderly (45%), at higher doses than recommended (31%) or with no appropriate clinical conditions (19%). From admission to discharge the prevalence of inappropriate BDZ prescription decreased by 4%, but 62% of patients inappropriately prescribed at admission were still inappropriately prescribed at discharge. Among the 179 patients first prescribed at the time of discharge, half were inappropriately prescribed. Being female (OR 1.32, 95%CI 0.95-1.85), enrolled in REPOSI during the years 2016 and 2017 (OR 1.94, 95%CI 1.10-3.39; OR 1.57, 95%CI 0.95-2.58) and living in nursing homes (OR 2.04, 95%CI 0.95-4.37) were associated with an increased risk to be inappropriately prescribed. This study shows a high prevalence of inappropriate use of BDZ in acutely hospitalized older patients both at hospital admission and discharge

Sex-Differences in the Pattern of Comorbidities, Functional Independence, and Mortality in Elderly Inpatients: Evidence from the RePoSI Register

Background: The RePoSi study has provided data on comorbidities, polypharmacy, and sex dimorphism in hospitalised elderly patients. Methods: We retrospectively analysed data collected from the 2010, 2012, 2014, and 2016 data sets of the RePoSi register. The aim of this study was to explore the sex-differences and to validate the multivariate model in the entire dataset with an expanded follow-up at 1 year. Results: Among 4714 patients, 51% were women and 49% were men. The disease distribution showed that diabetes, coronary artery disease, chronic obstructive pulmonary disease, chronic kidney disease, and malignancy were more frequent in men but that hypertension, anaemia, osteoarthritis, depression, and diverticulitis disease were more common 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, mood disorders, and disability in daily life measured by the Barthel Index (BI) were worse in women. In the multivariate analysis, BI, CIRS, and malignancy significantly increased the risk of death in men at the 1-year follow-up, while age was independently associated with mortality in women. Conclusions: Our study highlighted the relevance and the validity of our previous predictive model in the identification of sex dimorphism in hospitalised elderly patients underscoring the need of sex-personalised health-care

Use and prescription appropriateness of drugs for peptic ulcer and gastrooesophageal reflux disease in hospitalized older people.

Purpose The aims of this study were to assess the prevalence of use and prescription appropriateness of drugs for peptic ulcer and gastrooesophageal reflux disease (GERD) at hospital admission and discharge. Methods Patients aged 65 years or more hospitalized from 2010 to 2016 in 101 Italian internal medicine and geriatric wards in the context of the REPOSI register were scrutinized to assess if they were prescribed with drugs for peptic ulcer and GERD at hospital admission and discharge. Appropriateness of prescription was assessed considering the presence of specific conditions (i.e., history of peptic ulcer or gastrointestinal hemorrhages, advanced age, Helicobacter Pylori) or gastro-toxic drug combinations, according to the criteria provided by the reimbursement rules of the Agenzia Italiana del Farmaco (NOTA 1 and 48). Results Among 4715 enrolled patients, 3899 were discharged alive. At hospital discharge, 2412 (61.9%, 95%CI: 60.3–63.4%) patients were prescribed with drugs for peptic ulcer and GERD, a 12% of increase from hospital admission. Almost half of the patients (N = 1776, 45.6%, 95%CI: 44.0–47.1%) were inappropriately prescribed or not prescribed: among the drugs for peptic ulcer and GERD users, about 60% (1444/2412) were overprescribed, and among nonusers, 22% (332/1487) were underprescribed. Among patients newly prescribed at hospital discharge, 60% (392/668) were inappropriately prescribed. The appropriateness of drugs for peptic ulcer and GERD therapy decreased by 3% from hospital admission to discharge. Conclusions Hospitalization missed the opportunity to improve the quality of prescription of this class of drug
