A prospective cohort analysis of the prevalence and predictive factors of delayed discharge after laparoscopic cholecystectomy in Italy: the DeDiLaCo Study

Background: The concept of early discharge ≤24 hours after Laparoscopic Cholecystectomy (LC) is still doubted in Italy. This prospective multicentre study aims to analyze the prevalence of patients undergoing elective LC who experienced a delayed discharge >24 hours in an extensive Italian national database and identify potential limiting factors of early discharge after LC. Methods: This is a prospective observational multicentre study performed from January 1, 2021 to December 31, 2021 by 90 Italian surgical units. Results: A total of 4664 patients were included in the study. Clinical reasons were found only for 850 patients (37.7%) discharged >24 hours after LC. After excluding patients with nonclinical reasons for delayed discharge >24 hours, 2 groups based on the length of hospitalization were created: the Early group (≤24 h; 2414 patients, 73.9%) and the Delayed group (>24 h; 850 patients, 26.1%). At the multivariate analysis, ASA III class ( P <0.0001), Charlson's Comorbidity Index (P=0.001), history of choledocholithiasis (P=0.03), presence of peritoneal adhesions (P<0.0001), operative time >60 min (P<0.0001), drain placement (P<0.0001), pain ( P =0.001), postoperative vomiting (P=0.001) and complications (P<0.0001) were independent predictors of delayed discharge >24 hours. Conclusions: The majority of delayed discharges >24 hours after LC in our study were unrelated to the surgery itself. ASA class >II, advanced comorbidity, the presence of peritoneal adhesions, prolonged operative time, and placement of abdominal drainage were intraoperative variables independently associated with failure of early discharge

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

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

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
