GUTIERREZ-URBON, José María et al. PAUSATE Study: prevalence and appropriateness of the use of antimicrobials in Spanish hospitals. Farm Hosp. [online]. 2022, vol.46, n.5, pp.271-281.  Epub 19-Dic-2022. ISSN 2171-8695.


To determine the prevalence and appropriateness of antimicrobial use in Spanish hospitals through a pharmacist-led systematic cross-sectional review.


A nationwide multicenter cross-sectional study was conducted on 10% of the patients admitted to the participating hospitals on one day in April 2021. Hospital participation was voluntary, and the population was randomly selected. The study sample was made up of patients who, on the day of the study, received at least one antimicrobial belonging to groups J01, J02, J04, J05AB, J05AD or J05AH in the Anatomical Therapeutic Chemical Classification System. The pharmacist in charge made a record and carried out an evaluation of the appropriateness of antimicrobial use following a method proposed and validated by the Pharmaceutical Care of Patients with Infectious Diseases Working Group of the Spanish Society of Hospital Pharmacy. The evaluation method considered each of the items comprising antimicrobial prescriptions. An algorithm was used to assess prescriptions as appropriate, suboptimal, inappropriate and unevaluable.


One-hundred three hospitals participated in the study and the treatment of 3,568 patients was reviewed. A total of 1,498 (42.0%) patients received antimicrobial therapy, 424 (28.3%) of them in combination therapy. The most commonly prescribed antimicrobials were amoxicillin-clavulanic acid (7.2%), ceftriaxone (6.4%), piperacillin-tazobactam (5.8%), and meropenem 4.0%. As regards appropriateness, prescriptions were considered appropriate in 34% of cases, suboptimal in 45%, inappropriate in 19% and unevaluable in 2%. The items that most influenced the assessment of a prescription as suboptimal were completeness of medical record entries, choice of agent, duration of treatment and monitoring of efficacy and safety. The item that most influences the assessment of a prescription as inappropriate was the indication of antimicrobial agent.


The method used provided information on the prevalence and appropriateness of the use of antimicrobials, a preliminary step in the design and implementation of actions aimed at measuring the impact of the use of antimicrobials within the antimicrobial stewardship programs.
