On the surface, the answer to the question of the title of this editorial seemed to be a rhetorical and obvious yes. This is not because two pharmacists are involved in authoring this editorial, but because there is a substantial amount of literature-arguably more than which exists for any other clinical team member in the ICU and likely more than some of the standard-of-care interventions (such as mechanical ventilation)-which linked the presence of a pharmacist in an ICU to improved patient outcomes.Since the beginning of ICU clinical pharmacy services in the 1960s [1], the practice has matured along with the subspecialty of critical care medicine into one that has been considered by the Society of Critical Care Medicine (SCCM) as essential [2]. In fact, within the SCCM guidelines for best practice model and ICU staffing [2], pharmacist presence was considered as best practice supported by grade C evidence, the highest level of all recommendations in that document. A summary of the studies evaluating the impact of having a dedicated pharmacist in the ICU is shown in [3] clearly demonstrated that presence of pharmacists in a medical ICU reduced medication errors and cost. These benefits appear generalizable since the studies have been conducted in a variety of ICUs (e.g., medical, surgical, neurosurgical, cardiac, and pediatric) using different physician staffing models (e.g., open vs closed ICU), and date back to the early 1990s [13]. The majority of the studies have been conducted in North America, but similar beneficial results have been published from studies conducted in Asia [4,8,9], the Middle East [10], and Europe [11]. Provision of drug information, clarifying and correcting medication orders, identifying drug interactions as well as actual or potential adverse drug events, and recommending alternative therapies account for greater than 90 % of ICU pharmacists' activities [3,4,8,13,14]. The studies indicate that a large majority, and in most studies almost all, of pharmacists' recommendations are accepted by the physicians [3,4,[13][14][15]. These significant improvements in patient care afforded by the presence of dedicated pharmacists are clearly viewed as important by medical colleagues, as shown by a recent survey [16].In addition to the clear benefits for the patients, ICU pharmacists can play a multitude of other roles [17] such as education of other team members, leadership or administrative roles in critical care committees, and in Intensive Care Med (2015) 41:1314-1320
