Abstract Some patients in the community receive a high burden of antibiotics. We aimed at describing the characteristics of these patients, antibiotics used, and conditions for which they received antibiotics. We carried out a cross‐sectional study. Setting: Thirty Health Primary Care Areas from 12 regions in Spain, covering 5,960,191 inhabitants. Patients having at least 30 packages of antibacterials for systemic use dispensed in 2017 were considered. Main outcome measures: Prevalence of antibiotic use, conditions for which antibiotics were prescribed, clinical characteristics of patients, comorbidities, concomitant treatments, and microbiological isolates. Patient’s average age was 70 years; 52% were men; 60% smokers/ex‐smokers; 54% obese. Overall, 93% of patients had, at least, one chronic condition, and four comorbidities on average. Most common comorbidities were cardiovascular and/or hypertension (67%), respiratory diseases (62%), neurological/mental conditions (32%), diabetes (23%), and urological diseases (21%); 29% were immunosuppressed, 10% were dead at the time of data collection. Patients received three antibiotic treatments per year, mainly fluoroquinolones (28%), macrolides (21%), penicillins (19%), or cephalosporins (12%). Most frequently treated conditions were lower respiratory tract (infections or prophylaxis) (48%), urinary (27%), and skin/soft tissue infections (11%). Thirty‐five percent have been guided by a microbiological diagnosis, being Pseudomonas aeruginosa (30%) and Escherichia coli (16%) the most frequent isolates. In conclusion, high antibiotic consumers in the community were basically elder, with multimorbidity and polymedication. They frequently received broad‐spectrum antibiotics for long periods of time. The approach to infections in high consumers should be differentiated from healthy patients receiving antibiotics occasionally.

The aim of this study was to know the prevalence and severity of COVID-19 in patients treated with long-term macrolides and to describe the factors associated with worse outcomes. A cross-sectional study was conducted in Primary Care setting. Patients with macrolides dispensed continuously from 1 October 2019 to 31 March 2020, were considered. Main outcome: diagnosis of coronavirus disease-19 (COVID-19). Secondary outcomes: symptoms, severity, characteristics of patients, comorbidities, concomitant treatments. A total of 3057 patients met the inclusion criteria. Median age: 73 (64–81) years; 55% were men; 62% smokers/ex-smokers; 56% obese/overweight. Overall, 95% of patients had chronic respiratory diseases and four comorbidities as a median. Prevalence of COVID-19: 4.8%. This was in accordance with official data during the first wave of the pandemic. The most common symptoms were respiratory: shortness of breath, cough, and pneumonia. Additionally, 53% percent of patients had mild/moderate symptoms, 28% required hospital admission, and 19% died with COVID-19. The percentage of patients hospitalized and deaths were 2.6 and 5.8 times higher, respectively, in the COVID-19 group (p < 0.001). There was no evidence of a beneficial effect of long-term courses of macrolides in preventing SARS-CoV-2 infection or the progression to worse outcomes in old patients with underlying chronic respiratory diseases and a high burden of comorbidity.

Objective: The objective is to determine the prevalence of potentially inappropriate drugs according to the Marc, STOPP, and PRISCUS lists in elderly HIV patients., Methods: It was an observational, retrospective, and multicenter study. People living with HIV 65 years or older who underwent chronic concomitant treatment were included. Descriptive and multivariate analyzes were performed to study the association between polypharmacy and potentially inappropriate medication compliance., Results: A total of 55 patients were included, 81.8% men and a median age of 69 years (IQR: 67-73). The median number of comorbidities was 3 (IQR: 2-5) and the most frequent pattern of multimorbidity was cardiometabolic (62.9%). The predominant antiretroviral treatment was triple therapy (65.5%). Polypharmacy was present in 70.9% of the patients and 25.5% had major polypharmacy. The most frequent polypharmacy pattern was cardiovascular (69.2%). The percentage of potentially inappropriate medications according to the Marc, STOPP and PRISCUS lists was 65.5%, 30.9% and 14.5%, respectively (p<0.001). Adjusted for age and sex, polypharmacy was not independently associated with potentially inappropriate medication compliance in any of the lists., Conclusions: Polypharmacy and potentially inappropriate medications have a high prevalence. There is great variability in the percentage according to the list applied. Age, sex, and presence of polypharmacy are not predisposing factors to the presence of potentially inappropriate medications., (©The Author 2022. Published by Sociedad Española de Quimioterapia.
