BACKGROUND: The use of highly active antiretroviral therapy has significantly reduced morbidity and mortality, thus increasing life expectancy of human immunodeficiency virus (HIV)-infected individuals, transforming HIV into a chronic disease. Accordingly, there has been an increase in the number of comorbidities concomitantly present in these individuals and also an increased use of comedications, which may negatively impact antiretroviral therapy adherence. These factors can affect adherence to antiretroviral therapy. The role of the HIV clinical pharmacist is essential to achieve therapeutic objectives and enhance adherence.

Background Antimicrobial stewardship programs (ASPs) are recommended in nursing homes (NHs), although data are limited. This study aimed to determine the clinical and ecological impact of an ASP for NHs. Methods We performed a cluster randomized controlled trial and a before-after study with interrupted time-series analyses in 14 NHs, for 30 consecutive months from July 2018 to December 2020, in Andalusia, Spain. Seven facilities implemented an ASP with a bundle of five educational measures (general-ASP) and 7 added one-to-one educational interviews (experimental-ASP). The primary outcome was the overall use of antimicrobials, calculated monthly, as defined daily doses (DDD) per 1000 residents-day (DRD). Results During the ASP implementation, the total mean antimicrobial consumption decreased by 31.2% (-16.72 DRD; p = 0.045) with respect to the pre-intervention period; the overall use of quinolones and amoxicillin-clavulanic acid dropped by 52.2% (p = 0.001) and 42.5% (p = 0.006) respectively; and the overall prevalence of MDRO decreased from 24.7% to 17.4% (p = 0.012). During the intervention period, 12.5 educational interviews per doctor were done in the experimental ASP-group; no differences were found in the total mean antimicrobial use between groups (-14.62 DRD; p = 0.25) and two unexpected SARS-CoV-2 waves affected the participating centers with significant increases in the overall mean use of total antimicrobials of 40% (51.56 DRD; p < 0.0001). Conclusion This study suggests that an ASP for NHs appears to be associated with a decrease in total consumption of antimicrobials and prevalence of MDRO. This trial did not find benefits associated with educational interviews probably due to the COVID-19 pandemic.

Pharmacists may be tasked to lead antibiotic stewardship programmes (ASP) implementation in small hospitals in absence of infectious diseases (ID) physicians. The objectives are to evaluate the effectiveness of a pharmacist-led ASP in a hospital without ID physician support, with special focus on indicators of the hospital use of antimicrobial agents based on consumption and asess the potential clinical and economic impact of pharmacist interventions (PIs) through the CLEO tool. A prospective quasi-experimental study to implement an ASP in a 194-bed hospital. We evaluated changes in antimicrobial use measured as mean defined daily doses per 1000 patient-days (AUD) for intervention versus preintervention period. A total of 847 antimicrobial PIs were proposed, being 88.3% accepted. Discontinuation due to excessive duration was the most frequently performed PI (23.4%). Most of PIs was classified as major or moderate clinical impact, 41.7% and 37.8% respectively. The global consumption of antimicrobial was reduced from 907.1 to 693.8 AUD, with a signifcant drop in carbapenems and quinolones. Direct expenditure of antibiotics decreased significantly. Pharmacist-led ASP has being effective in reducing consumption of antibiotics. In the absence of ID physician´s support and oversight, pharmacists could lead the improvement of the use of antimicrobials.

Antimicrobials are the most frequently prescribed drugs in long-term care facilities (LTCF). Antibiotic stewardship programs (ASP) are coordinated interventions promoting the responsible use of antibiotics to improve patient outcomes and reduce antibiotic resistant bacterias. The objectives are to evaluate the effectiveness of a pharmacist-led ASP in a LTCF, to characterise antibiotic therapy and assess the appropriateness of antibiotic prescriptions. A prospective quasi-experimental study to implement an ASP in a LTCF. Antibiotic prescriptions for suspected infections initiated in any setting for LTCF residents were included. We assessed appropriateness and prospective audits and feedback of each inappropriate antimicrobial prescription were carried out. Associations of variables with appropriate antibiotic prescribing were estimated using logistic regression. A total of 416 antibiotic prescriptions were included. The mean consumption of antibiotics was reduced from 63.2 defined daily doses per 1000 residents-days (DRD) in the preintervention period to 22.8 in the intervention period (− 63.8%), with a signifcant drop in fluoroquinolones (81.4%). Overall, 46.6% of antibiotic prescriptions were judged inappropriate, mainly because of a use not recommended in treatment guidelines (63.2%). Multivariable analysis showed that empirical therapy, some classes of antibiotics (cephalosporins, fluoroquinolones, fosfomycin calcium, macrolides) and prescription initiation in the emergency department were independent predictors of antimicrobial inappropriateness. Pharmacist-led ASP in a LTCF has being effective in reducing consumption of antibiotics by improving appropriateness of treatment decisions. However, ASP should include interventions in the emergency department because of the high inappropriate use in this setting.
