Clinical pharmacy interventions in intensive care unit patients

What is known and objective The drug therapy of critically ill patients requires intensive evaluation and management due to their severity of illness. These patients often require complex medication regimens. This study analysed the pharmaceutical care provided by clinical pharmacists (CPs) in a single medical centre in Taiwan. In addition, we explored the drug-related problems (DRPs) experienced by patients in intensive care units (ICUs) to determine how to improve the quality and safety of drug therapy. Methods This retrospective study was conducted from February 2019 to January 2020. The CPs implemented Taiwan's National Health Insurance (NHI) Scheme for Improving Hospital Drug Safety and Quality programme to improve the safety and quality of drug therapy. The CPs included in the study had at least 2 years' clinical experience and had participated in an ICU team for at least 6 consecutive months. They provided individualized drug treatment evaluation and intervention. Content of care was documented in the Clinical Pharmacy Service Record. Results and discussion A total of 4374 pharmacy care records were evaluated by 12 CPs. The major category of ICU pharmaceutical care was medication reconciliation (n = 2938; 67.2%). Most of the medication interventions were for errors in dosing or dosing frequency (n = 218; 55.8%). Patients with renal dysfunction required more pharmaceutical interventions than did patients with normal renal function (odds ratio = 1.63; 95% confidence interval 1.31-2.01). The main interventions were related to antimicrobial agents (n = 386; 81.3%). During the study period, 99.2% of interventions were accepted and 90.8% were changed within 24 hours. What is new and conclusion Increased pharmaceutical interventions for patients with renal dysfunction compared with patients with normal renal function were observed. Most cases of inappropriate frequency of dosing or dosing of antimicrobial agents required intervention.
