The prevalence of polypharmacy in older Europeans: A multi-national database study of general practitioner prescribing.

AIMS: The aims of this study were to measure the prevalence of polypharmacy and describe the prescribing of selected medications known for overuse in older people with polypharmacy in primary care. METHODS: This was a multinational retrospective cohort study across six countries: Belgium, France, Germany, Italy, Spain and the UK. We used anonymized longitudinal patient-level information from general practice databases hosted by IQVIA. Patients ≥65 years were included. Polypharmacy was defined as having 5-9 and ≥10 distinct drug classes (ATC Level 3) prescribed during a 6-month period. Selected medications were: opioids, antipsychotics, proton pump inhibitors (PPI), benzodiazepines (ATC Level 5). We included country experts on the healthcare context to interpret findings. RESULTS: Age and gender distribution was similar across the six countries (mean age 75-76 years; 54-56% female). The prevalence of polypharmacy of 5-9 drugs was 22.8% (UK) to 58.3% (Germany); ≥10 drugs from 11.3% (UK) to 28.5% (Germany). In the polypharmacy population prescribed ≥5 drugs, opioid prescribing ranged from 11.5% (France) to 27.5% (Spain). Prescribing of PPI was highest with almost half of patients receiving a PPI, 42.3% (Germany) to 65.5% (Spain). Benzodiazepine prescribing showed a marked variation between countries, 2.7% (UK) to 34.9% (Spain). The healthcare context information explained possible underreporting for selected medications. CONCLUSIONS: We have found a high prevalence of polypharmacy with more than half of the older population being prescribed ≥5 drugs in four of the six countries. Whilst polypharmacy may be appropriate in many patients, worryingly high usage of PPIs and benzodiazepines supports current efforts to improve polypharmacy management across Europe.

Hospital Burden of All-Cause Pneumonia and Nonbacteremic Pneumococcal Pneumonia in Adults in France Between 2013 and 2019.

Background: Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality. The study objective was to describe the hospital burden of pneumonia in the adult population in France. Methods: This retrospective study was conducted from the National Health Insurance Database. All hospitalizations for pneumonia (all-cause) between 2013 and 2019 were included. Different risk categories for patients were established based on pneumococcal vaccine recommendations by French health authorities. Results: A total of 2 199 240 episodes of CAP were registered over the study period (annual mean, 314 177 [standard deviation, 17 818.6]); 75% occurred in patients aged ≥65 years, among whom 47% were not classified in the moderate- or high-risk categories recommended for French pneumococcal vaccination. The incidence of CAP increased with age (117.9, 395.3, and 1916.7 per 100 000 for the age groups 18-49, 50-64, and ≥65 years, respectively, in 2019). Furthermore, being at risk of pneumococcal disease resulted in more severe outcomes, including longer episode duration (mean, 14 days in low-risk vs 17 days in high-risk patients) and higher risk of referral to critical care units (from 20% to 27%), of rehospitalization up to 180 days (from 39% to 67%), of in-hospital death (from 12% to 19%), and of 1-year mortality (from 26% to 49%). Conclusions: This study establishes the incidence of CAP in adults in France, describes the significant burden of disease, and highlights the need for better prevention policies.
