Evaluation of Sepsis-Related Medical Emergency Team (MET) Calls with Pharmacist Involvement and Time to Antimicrobial Administration

<b>Objective:</b> To evaluate the difference in proportion of patients receiving antimicrobials within one hour of sepsis recognition at sepsis-related Medical Emergency Team (MET) calls, without or with a sepsis-credentialed pharmacist. <b>Design:</b> Retrospective pre and post-intervention study. <b>Setting:</b> Single centre tertiary referral hospital. <b>Participants:</b> Patients admitted to the General Medicine Unit who had a sepsis-related MET call 24 hrs per day, and all other units from 17:00-08:00 hrs from August 2019 to Jan 2020 in the pre-intervention cohort and Aug 2020 to Jan 2021 for the post-intervention cohort. <b>Interventions:</b> Pharmacists attended MET calls to assist selection of antimicrobials, collaboratively prescribe with the medical officers, ensure supply, provide advice on dosing calculations, reconstitution, and administration. The pre-intervention cohort (Aug 2019-Jan 2020) did not have credentialed pharmacists' involvement at MET calls. <b>Outcome Measures:</b> Proportion of patients who received antimicrobials within one hours of MET call. <b>Results:</b> There were 97 sepsis-related MET calls in the pre-intervention cohort and 110 sepsis-related MET calls in the post-intervention cohort. A significantly higher proportion of patients received antimicrobials within one hour with pharmacist involvement, compared to control (81.3% vs 59.7%, <i>P</i> = .0006). A reduction in median time to antimicrobial administration (43 min vs 54 min, <i>P</i> = .017) was observed. <b>Conclusion:</b> Sepsis-related MET calls with pharmacist involvement experienced a greater proportion of patients receiving antimicrobials within one hour of sepsis recognition, and a reduction in median time to antimicrobial administration. These results provide support for routine pharmacist involvement at MET calls to assist patients receiving medications in a timely and efficient manner.
