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\u20132017 REPOSI register held in more than 100 internal medicine and geriatric wards in Italy. Patients aged 6565 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 \u3b2- 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\u20133.48) 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\u2013drug 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 Societ\ue0 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\u20139.2). 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

Disability, and not diabetes, is a strong predictor of mortality in oldest old patients hospitalized with pneumonia

Background: Pneumonia causes more deaths than any other infectious disease, especially in older patients with multiple chronic diseases. Recent studies identified a low functional status as prognostic factor for mortality in elderly patients with pneumonia while contrasting data are available about the role of diabetes. The aim of this study was to evaluate the in-hospital, 3-month and 1-year mortality in elderly subjects affected by pneumonia enrolled in the RePoSi register.Methods: We retrospectively analyzed the data collected on hospitalized elderly patients in the frame of the REPOSI project. We analyzed the socio-demographic, laboratory and clinical characteristics of subjects with pneumonia. Multivariate logistic analysis was used to explore the relationship between variables and mortality.Results: Among 4714 patients 284 had pneumonia. 52.8% were males and the mean age was 80 years old. 19.8% of these patients had a Barthel Index <= 40 (p < 0.0001), as well as 43.2% had a short blessed test >= 10 (p < 0.0117). In these subjects a significant CIRS for the evaluation of severity and comorbidity indexes (p < 0.0001) were present. Although a higher fasting glucose level was identified in people with pneumonia, in the multivariate logistic analysis diabetes was not independently associated with in-hospital, 3-month and 1-year mortality, whereas patients with lower Barthel Index had a higher mortality risk (odds ratio being 9.45, 6.84, 19.55 in hospital, at 3 and 12 months).Conclusion: Elderly hospitalized patients affected by pneumonia with a clinically significant disability had a higher mortality risk while diabetes does not represent an important determinant of short and long-term outcome

Prevalence, characteristics and treatment of chronic pain in elderly patients hospitalized in internal medicine wards.

BACKGROUND: Chronic pain is a frequent characteristic of elderly people and represents an actual and still poorly debated topic. OBJECTIVE: We investigated pain prevalence and intensity, and its pharmacological therapy in elderly patients hospitalized in 101 internal medicine wards. METHODS: Taking advantage of the "REgistro POliterapie Società Italiana Medicina Interna" (REPOSI), we collected 2535 patients of whom almost a quarter was older than 85 years old. Among them, 582 patients were affected by pain (either chronic or acute) and 296 were diagnosed with chronic pain. RESULTS: Patients with pain showed worse cognitive status, higher depression and comorbidities, and a longer duration of hospital stay compared to those without pain (all p < .0366). Patients with chronic pain revealed lower level of independency in their daily life, worse cognitive status and higher level of depression compared to acute pain patients (all p < .0156). Moreover, most of them were not treated for pain at admission (73.4%) and half of them was not treated with any analgesic drug at discharge (50.5%). This difference affected also the reported levels of pain intensity. Patients who received analgesics at both admission and discharge remained stable (p = .172). Conversely, those not treated at admission who received an analgesic treatment during the hospital stay decreased their perceived pain (p < .0001). CONCLUSIONS: Our results show the need to focus more attention on the pharmacological treatment of chronic pain, especially in hospitalized elderly patients, in order to support them and facilitate their daily life after hospital discharge

Therapeutic Duplicates in a Cohort of Hospitalized Elderly Patients: Results from the REPOSI Study

Background: Explicit criteria for potentially inappropriate prescriptions in the elderly are recommended to avoid prescriptions of duplicate drug classes and to optimize monotherapy within a single drug class before a new agent is considered. Duplicate drug class prescription (or therapeutic duplicates) puts the patient at increased risk of adverse drug reactions with no additional therapeutic benefits. To our knowledge, the prevalence of elderly inpatients receiving therapeutic duplicates has never been studied. Objectives: Our objective was to assess the prevalence of therapeutic duplicates at admission, discharge, and 3-month follow-up of hospitalized elderly patients. Methods: This cross-sectional prospective study was conducted in 97 Italian internal medicine and geriatric wards. Therapeutic duplicates were defined as at least two drugs of the same therapeutic class prescribed simultaneously to a patient. A patient\u2019s drug therapy at admission relates to prescriptions from general practitioners, whereas prescriptions at discharge are those from hospital internists or geriatricians. Results: The study sample comprised 5821 admitted and 4983 discharged patients. In all, 143 therapeutic duplicates were found at admission and 170 at discharge. The prevalence of patients exposed to at least one therapeutic duplicate rose significantly from hospital admission (2.5 %) to discharge (3.4 %; p = 0.0032). Psychotropic drugs and drugs for peptic ulcer or gastroesophageal reflux disease were the most frequently involved. A total of 86.8 % of patients discharged with at least one therapeutic duplicate were still receiving them at 3-month follow-up. Conclusions: Hospitalization and drugs prescribed by internists and geriatricians are both factors associated with a small but definite increase in overall therapeutic duplicates in elderly patients admitted to internal medicine and geriatric wards. More attention should be paid to the indications for each drug prescribed, because therapeutic duplicates are not supported by evidence and increase both the risk of adverse drug reactions and costs. Identification of unnecessary therapeutic duplicates is essential for the optimization of polypharmacy
