Use of Lipid-Lowering Drugs and Associated Outcomes According to Health State Profiles in Hospitalized Older Patients.

OBJECTIVE: To assess how lipid-lowering drugs (LLDs) are administered in the hospitalized patients aged 65 and older and their association with clinical outcomes according to their health-related profiles. DESIGN: This is a retrospective study based on data from REPOSI (REgistro POliterapie SIMI - Italian Society of Internal Medicine) register, an Italian network of internal medicine hospital wards. SETTING AND PARTICIPANTS: A total of 4642 patients with a mean age of 79 years enrolled between 2010 and 2018. METHODS: Socio-demographic characteristics, functional abilities, cognitive skills, laboratory parameters and comorbidities were used to investigate the health state profiles by using multiple correspondence analysis and clustering. Logistic regression was used to assess whether LLD prescription was associated with patients' health state profiles and with short-term mortality. RESULTS: Four clusters of patients were identified according to their health state: two of them (Cluster III and IV) were the epitome of frailty conditions with poor short-term outcomes, whereas the others included healthier patients. The average prevalence of LLD use was 27.6%. The lowest prevalence was found among the healthier patients in Cluster I and among the oldest frail patients with severe functional and cognitive impairment in Cluster IV. The highest prevalence was among multimorbid patients in Cluster III (OR=4.50, 95% CI=3.76-5.38) characterized by a high cardiovascular risk. Being prescribed with LLDs was associated with a lower 3-month mortality, even after adjusting for cluster assignment (OR=0.59; 95% CI = 0.44-0.80). CONCLUSION: The prevalence of LLD prescription was low and in overall agreement with guideline recommendations and with respect to patients' health state profiles.

Management of high cholesterol levels in older people.

The management of hypercholesterolemia in older adults still represents a challenge in clinical medicine. The pathophysiological alterations of cholesterol metabolism associated with aging are still incompletely understood, even if epidemiological evidence suggests that serum cholesterol levels increase with ongoing age, possibly with a plateau after the age of 80 years. Age is also one of the main determinants of cardiovascular disease, according to all cardiovascular risk estimate tools. Cholesterol-lowering treatment, therefore, would be expected to bring significant protection, even in these patients. Unfortunately, direct experimental evidence is extremely limited, particularly in the very old age strata of the population; a clinical benefit still seems to be present, but the risk for drug-related adverse events is clearly higher. At any rate, at the present time, definite guidelines for the correct management of hypercholesterolemia in older patients are not available. Therefore, the decision whether or not a pharmacological treatment should be set up, and the choice of the drug, need to be tailored to the individual patient, and requires accurate clinical judgment. The specific aspects of frailty and disability, along with the actual age of the patients, have to be considered together, with a comprehensive assessment approach. The present review summarizes the evidence regarding the modifications of cholesterol metabolism in older patients, the impact of lipid-lowering drugs on cardiovascular outcomes and focuses on the considerations that can help to define the most appropriate treatment strategy, in view of the individual functional profile.

Prevalence and Determinants of the Use of Lipid-Lowering Agents in a Population of Older Hospitalized Patients: the Findings from the REPOSI (REgistro POliterapie Società Italiana di Medicina Interna) Study.

BACKGROUND: Older patients are prone to multimorbidity and polypharmacy, with an inherent risk of adverse events and drug interactions. To the best of our knowledge, available information on the appropriateness of lipid-lowering treatment is extremely limited. AIM: The aim of the present study was to quantify and characterize lipid-lowering drug use in a population of complex in-hospital older patients. METHODS: We analyzed data from 87 units of internal medicine or geriatric medicine in the REPOSI (Registro Politerapie della Società Italiana di Medicina Interna) study, with reference to the 2010 and 2012 patient cohorts. Lipid-lowering drug use was closely correlated with the clinical profiles, including multimorbidity markers and polypharmacy. RESULTS: 2171 patients aged >65 years were enrolled (1057 males, 1114 females, mean age 78.6 years). The patients treated with lipid-lowering drugs amounted to 508 subjects (23.4%), with no gender difference. Atorvastatin (39.3%) and simvastatin (34.0%) were the most widely used statin drugs. Likelihood of treatment was associated with polypharmacy (≥5 drugs) and with higher Cumulative Illness Rating Scale (CIRS) score. At logistic regression analysis, the presence of coronary heart disease, peripheral vascular disease, and hypertension were significantly correlated with lipid-lowering drug use, whereas age showed an inverse correlation. Diabetes was not associated with drug treatment. CONCLUSIONS: In this in-hospital cohort, the use of lipid-lowering agents was mainly driven by patients' clinical history, most notably the presence of clinically overt manifestations of atherosclerosis. Increasing age seems to be associated with lower prescription rates. This might be indicative of cautious behavior towards a potentially toxic treatment regimen.
