Do prehospital sepsis alerts decrease time to complete CMS sepsis measures?

In an effort to improve sepsis outcomes the Centers for Medicare and Medicaid Services (CMS) established a time sensitive sepsis management bundle as a core quality measure that includes blood culture collection, serum lactate collection, initiation of intravenous fluid administration, and initiation of broad-spectrum antibiotics. Few studies examine the effects of a prehospital sepsis alert protocol on decreasing time to complete CMS sepsis core measures. This study was a retrospective cohort study of patients transported via EMS from December 1, 2018 to December 1, 2019 who met the criteria of the Maryland Statewide EMS sepsis protocol and compared outcomes between patients who activated a prehospital sepsis alert and patients who did not activate a prehospital sepsis alert. The Maryland Institute for Emergency Medical Services Systems developed a sepsis protocol that instructs EMS providers to notify the nearest appropriate facility with a sepsis alert if a patient 18 years of age and older is suspected of having an infection and also presents with at least two of the following: temperature >38 °C or <35.5 °C, a heart rate >100 beats per minute, a respiratory rate >25 breaths per minute or end-tidal carbon dioxide less than or equal to 32 mmHg, a systolic blood pressure <90 mmHg, or a point of care lactate reading greater than or equal to 4 mmol/L. Median time to achieve all four studied CMS sepsis core measures was 103 min [IQR 61-153] for patients who received a prehospital sepsis alert and 106.5 min [IQR 75-189] for patients who did not receive a prehospital sepsis alert (p-value 0.105). Median time to completion was shorter for serum lactate collection (28 min. vs 35 min., p-value 0.019), blood culture collection (28 min. vs 38 min., p-value <0.01), and intravenous fluid administration (54 min. vs 61 min., p-value 0.025) but was not significantly different for antibiotic administration (94 min. vs 103 min., p-value 0.12) among patients who triggered a sepsis alert. This study questions the effectiveness of prehospital sepsis alert protocols on decreasing time to complete CMS sepsis core measures. Future studies should address if these times can be impacted by having EMS providers independently administer antibiotics.
