Abstract

Background: Acute ischemic stroke (AIS) requires time-sensitive fibrinolytic therapy measured by door-to-needle (DTN) time. Emergency medicine pharmacists (EMPs) are integral in emergency departments (EDs) for optimizing AIS care as they possess expertise in drug therapy and emergency response.

Objective: The purpose of this systematic review and meta-analysis (SR/MA) is to evaluate EMP impact on DTN time.

Methods: This SR/MA searched multiple databases. Eligibility criteria included adult ED patients with AIS receiving fibrinolytics with defined EMP involvement. The primary endpoint was fibrinolytic DTN time. Secondary endpoints included achievement of timely fibrinolytic and length of stay (LOS). Meta-analysis was conducted using random-effects models.

Results: Of 494 total citations identified, 214 citations met screening criteria with 22 studies undergoing full text review and 9 observational, retrospective, cohort studies included. A total of 1064 patients were included for MA with 441 (41.4 %) in the EMP present group and 623 (58.6 %) in the EMP absent group. EMP presence was associated with reduced mean DTN time by 14.6 min (95 % CI -18.1, -11.1 min). Odds of achieving a DTN within 60- and 45-min was higher with EMP presence, OR 2.85 (95 % CI 1.40, 5.79) and 2.75 (95 % CI 1.99, 3.79), respectively. ICU LOS was longer by 2.07 days in the EMP present group, but hospital LOS was not different between groups.

Conclusions: EMP presence during AIS management is associated…
