Polypharmacy, resulting from the medications used in the management of sepsis, along with the pharmacokinetic changes induced by sepsis, can place this patient population at increased risk for drug-related problems (DRPs). Clinical pharmacists contribute to reducing DRPs by providing medication review services, which involve a comprehensive evaluation of a patient's medications. The aim of this study was to identify and classify DRPs in patients with sepsis and septic shock who were hospitalized in the intensive care unit (ICU), and to evaluate the effect of clinical pharmacist-led medication review on DRPs. The study was a prospective, non-randomized controlled study conducted in the medical ICU of a tertiary education and research hospital in Istanbul, Türkiye, from October 2023 to May 2024. The study design included both observation periods (OP) and intervention periods (IP). During the IP, the clinical pharmacist provided recommendations to prevent or resolve DRPs during daily rounds and conducted DRP-reducing presentations to the clinical team on DRPs frequently observed during the OP. DRPs were classified according to Pharmaceutical Care Network (PCNE) Version 9.1 and their clinical significance in collaboration with the chief of ICU. A total of 60 patients were included in the study. The mean age of all patients was 62.6 ± 17.4 years and 58.3% were male. A total of 354 (5.9/patient) DRPs were detected in all periods. Of these DRPs, 50.1% were classified as "adverse drug event (possibly) occurring", 30.8% as "effect of drug treatment not optimal", 5.6% as "unnecessary drug treatment", 2.8% as "untreated symptoms or indications", and 10.7% as "unclear problem/complaint". In the IP, the number of all DRPs decreased by 63.3% (p < 0.001) and the frequency of clinically significant major DRPs decreased by 84.8% (p = 0.008). During the IP, recommendations were made for 72 of the 95 DRPs identified and 70 of these recommendations (97.2%) were accepted by physicians. A high incidence of DRP was detected in patients with sepsis hospitalized in the ICU. The majority of clinical pharmacist recommendations were accepted by the ICU team. The number of DRPs decreased significantly during the IP.
