Abstract
AbstractBest practices of pain, agitation, and delirium (PAD) management require coordinated, bundled care among an interprofessional intensive care unit (ICU) team. Clinical pharmacists are essential health care team members in optimizing sedation and analgesia management in critically ill patients. The purpose of this systematic review is to summarize the clinical impact of pharmacist‐led interventions targeting PAD in mechanically ventilated adult ICU patients. A literature search was conducted using MEDLINE, EMBASE, CINAHL, SCOPUS, and the Cochrane Central Register of Controlled Trials between January 1, 2000 and September 1, 2022. Randomized controlled trials, quasi‐experimental, or observational studies comparing pharmacist‐led interventions aimed at PAD management best practices and usual care in adult (≥18 years) ICU patients were included. Clinical (mechanical ventilation duration, hospital length of stay, and mortality) and economic outcomes as well as sedation and analgesia utilization were evaluated. A total of 1418 citations were identified with 9 studies (n = 3769 patients) meeting eligibility. The types of pharmacist‐led intervention strategies were inconsistent among included studies. Four of the 9 studies showed that pharmacist‐led interventions were associated with a significant reduction in mechanical ventilation duration ranging from 4.0 to 8.5 days compared with approximately 5.6 to 14.0 days in the control groups. Three (50%) of 6 studies evaluating length of stay showed significant reductions with the intervention group compared with controls. No impact on mortality and ICU‐acquired delirium/coma rates was shown. The pharmacist‐led intervention group was also associated with significant reductions in opioid analgesia and sedative utilization. Only two studies evaluated the financial impact of the intervention group with one study finding a positive benefit attributed to decreased drug utilization, while the other report failed to find an impact on total hospital stay costs. Pharmacist‐led interventions promote PAD best practices in the ICU, although the impact on patient‐centered outcomes remains controversial.
