RESUMEN
OBJECTIVE: To determine if the introduction of an emergency department (ED) sepsis screening tool and management bundle affects antibiotic prescribing and use. DESIGN: Multicentre, cohort, before-and-after study design. SETTING: Three tertiary hospitals in Queensland, Australia (median bed size 543, range 520-742). PARTICIPANTS: Adult patients, presenting to the ED with symptoms and signs suggestive of sepsis who had blood cultures collected. These participants were further assessed and stratified as having septic shock, sepsis or infection alone, using Sepsis-3 definitions. The study dates were 1 July 2017-31 March 2020. INTERVENTION: The breakthrough series collaborative 'Could this be Sepsis?' Programme, aimed at embedding a sepsis screening tool and treatment bundle with weighted-incidence syndromic combined antibiogram-derived antibiotic guidelines in EDs. MAIN OUTCOME MEASURES: The primary outcome was the rate of empirical prescriptions adherent to antibiotic guidelines during the ED encounter. Secondary outcomes included the empirical prescriptions considered appropriate, effective antibiotics administered within 3 hours and assessment of harm measures. RESULTS: Of 2591 eligible patients, 721 were randomly selected: 241 in the baseline phase and 480 in the post-intervention phase. The rates of guideline adherence were 54.0% and 59.5%, respectively (adjusted OR (aOR) 1.41 (95% CI 1.00, 1.98)). As compared with baseline, there was an increase in the rates of appropriate antibiotic prescription after bundle implementation (69.9% vs 57.1%, aOR 1.92 (95% CI 1.37, 2.68)). There were no differences between the baseline and post-intervention groups with respect to time to effective antibiotics, adverse effects or ED rates of broad-spectrum antibiotic use. CONCLUSION AND RELEVANCE: The use of an ED sepsis screening tool and management bundle was associated with an improvement in the rates of appropriate antibiotic prescription without evidence of adverse effects.

Purpose: To assess accuracy of early diagnosis, appropriateness and timeliness of response, and clinical outcomes of older general medical inpatients with hospital-acquired sepsis. Methods: Hospital abstracts of inpatient encounters from seven digital Queensland public hospitals between July 2018 and September 2020 were screened retrospectively for diagnoses of hospital-acquired sepsis. Electronic medical records were retrieved and cases meeting selection criteria and classified as confirmed or probable sepsis using pre-specified criteria were included. Investigations and treatments following the first digitally generated alert of clinical deterioration were compared with a best practice sepsis care bundle. Outcome measures comprised 30-day all-cause mortality after deterioration, and unplanned readmissions at 14 days after discharge. Results: Of the 169 screened care episodes, 59 comprised probable or confirmed cases of sepsis treated by general medicine teams at the time of initial deterioration. Of these, 43 (72.9%) had no mention of sepsis in the differential diagnosis on first medical review, and only 38 (64%) were managed as having sepsis. Each care bundle component of blood cultures, serum lactate, and intravenous fluid resuscitation and antibiotics was only delivered in approximately 30% of cases, and antibiotic administration was delayed more than an hour in 28 of 38 (73.7%) cases. Conclusion: Early recognition of sepsis and timely implementation of care bundles are challenging in older general medical patients. Education programs in sepsis care standards targeting nurses and junior medical staff, closer patient monitoring, and post-discharge follow-up may improve patient outcomes.
RESUMEN
BACKGROUND: Sepsis bundles, promulgated by Surviving Sepsis Campaign have not been widely adopted because of variability in sepsis identification strategies, implementation challenges, concerns about excess antimicrobial use, and limited evidence of benefit. METHODS: A 1-hour septic shock and a 3-hour sepsis bundle were implemented using a Breakthrough Series Collaborative in 14 public hospitals in Queensland, Australia. A before (baseline) and after (post-intervention) study evaluated its impact on outcomes and antimicrobial prescription in patients with confirmed bacteremia and sepsis. FINDINGS: Between 01 July 2017 to 31 March 2020, of 6976 adults presenting to the Emergency Departments and had a blood culture taken, 1802 patients (732 baseline, 1070 post-intervention) met inclusion criteria. Time to antibiotics in 1-hour 73.7% vs 85.1% (OR 1.9 [95%CI 1.1-3.6]) and the 3-hour bundle compliance (48.2% to 63.3%, OR 1.7, [95%CI 1.4 to 2.1]) improved post-intervention, accompanied by a significant reduction in Intensive Care Unit (ICU) admission rates (26.5% vs 17.5% (OR 0.5, [95%CI 0.4 to 0.7]). There were no significant differences in-hospital and 30-day post discharge mortality between the two phases. In a post-hoc analysis of the post-intervention phase, sepsis pathway compliance was associated with lower in-hospital mortality (9.7% vs 14.9%, OR 0.6, 95%CI 0.4 to 0.8). The proportions of appropriate antimicrobial prescription at baseline and post-intervention respectively were 55.4% vs 64.1%, (OR 1.4 [95%CI 0.9 to 2.1]). INTERPRETATION: Implementing 1-hour and 3-hour sepsis bundles for patients presenting with bacteremia resulted in improved bundle compliance and a reduced need for ICU admission without adversely influencing antimicrobial prescription.
