Blood culture algorithm implementation in emergency department patients as a diagnostic stewardship intervention.

OBJECTIVE: Blood cultures (BCx) are important for selecting appropriate antibiotic treatment. Ordering BCx for conditions with a low probability of bacteremia has limited utility, thus improved guidance for ordering BCx is needed. Inpatient studies have implemented BCx algorithms, but no studies examine the intervention in an Emergency Department (ED) setting. METHODS: We performed a quasi-experimental pre and postintervention study from January 12, 2020, to October 31, 2023, at a single academic adult ED and implemented a BCx algorithm. The primary outcome was the blood culture event rates (BCE per 100 ED admissions) pre and postintervention. Secondary outcomes included adverse event rates (30-day ED and hospital readmission and antibiotic days of therapy). Seven ED physicians and APP reviewed BCx for appropriateness, with monthly feedback provided to ED leadership and physicians. RESULTS: After the BCx algorithm implementation, the BCE rate decreased from 12.17 BCE/100 ED admissions to 10.50 BCE/100 ED admissions. Of the 3,478 reviewed BCE, we adjudicated 2,153 BCE (62%) as appropriate, 653 (19%) as inappropriate, and 672 (19%) as uncertain. Adverse safety events were not statistically different pre and postintervention. CONCLUSIONS: Implementation of an ED BCx algorithm demonstrated a reduction in BCE, without increased adverse safety events. Future studies should compare outcomes of BCx algorithm implementation in a community hospital ED without intensive chart review.

Parent Perspectives During Hospital Readmissions for Children With Medical Complexity: A Qualitative Study.

OBJECTIVES: Children with medical complexity (CMC) have high readmission rates, but relatively little is known from the parent perspective regarding care experiences surrounding and factors contributing to readmissions. We aimed to elicit parent perspectives on circumstances surrounding 30-day readmissions for CMC. METHODS: We conducted 20 semistructured interviews with parents of CMC experiencing an unplanned 30-day readmission at 1 academic medical center between December 2016 and January 2018, asking about topics such as previous discharge experiences, medical services and resources, and home environment and social support. Interviews were recorded, professionally transcribed, and analyzed thematically by using a modified grounded theory approach. RESULTS: Children ranged in age from 0 to 15 years, with neurologic complex chronic conditions being predominant (35%). Although the majority of parents did not identify any factors that they perceived to have contributed to readmission, themes emerged regarding challenges associated with chronicity of care and transitions of care that might influence readmissions, including frequency of hospital use, symptom confusion, lack of inpatient continuity, resources needed but not received, and difficulty filling prescriptions. CONCLUSIONS: Parents identified multiple challenges associated with chronicity of medical management and transitions of care for CMC. Future interventions aiming to improve continuity and communication between admissions, ensure that home services are provided when applicable and prescriptions are filled, and provide comprehensive support for families in both the short- and long-term may help improve patient and family experiences while potentially decreasing readmissions.
