Appropriate empirical antibiotic use in the emergency department: full compliance matters!

ABSTRACT:

Background

Little is known about determinants of appropriate antibiotic use in the emergency department (ED). We measured appropriateness of antibiotic use for seven quality indicators (QIs) and studied patient-related factors that determine their variation.

Patients and methods

A retrospective analysis of 948 patients presumptively diagnosed as having an infection needing empirical antibiotic treatment in the ED was performed. Outcomes of seven previously validated QIs were calculated using computerized algorithms. We used logistic regression analysis to identify patient-related factors of QI performance and evaluated whether more appropriate antibiotic use in the ED results in better patient outcomes (length-of-stay, in-hospital mortality, 30 day readmission).

Results

QI performance ranged from 57.3% for guideline-adherent empirical therapy to 97.3% for appropriate route of administration in patients with sepsis. QI performance was positively associated with patients' disease severity on admission (presence of fever, tachycardia and hypotension). Overall, the clinical diagnosis and thus the guidelines followed influenced QI performance. The difference in complexity between the guidelines was a possible explanation for the variation in QI performance. A QI performance sum score of 100% was associated with reduced in-hospital mortality. QI performance was not associated with readmission rates.

Conclusions

We gained insights into factors that determine quality of antibiotic prescription in the ED. Adherence to the full bundle of QIs was associated with reduced in-hospital mortality. These findings suggest that future stewardship interventions in the ED should focus on the entire process of antibiotic prescribing in the ED and not on a single metric only.

Project description:ImportanceMaternal emergency department (ED) use before or during pregnancy is associated with worse obstetrical outcomes, for reasons including preexisting medical conditions and challenges in accessing health care. It is not known whether maternal prepregnancy ED use is associated with higher use of the ED by their infant.ObjectiveTo study the association between maternal prepregnancy ED use and risk of infant ED use in the first year of life.Design, setting, and participantsThis population-based cohort study included all singleton livebirths in all of Ontario, Canada, from June 2003 to January 2020.ExposuresAny maternal ED encounter within 90 days preceding the start of the index pregnancy.Main outcomes and measuresAny infant ED visit up to 365 days after the index birth hospitalization discharge date. Relative risks (RR) and absolute risk differences (ARD) were adjusted for maternal age, income, rural residence, immigrant status, parity, having a primary care clinician, and number of prepregnancy comorbidities.ResultsThere were 2 088 111 singleton livebirths; the mean (SD) maternal age was 29.5 (5.4) years, 208 356 (10.0%) were rural dwelling, and 487 773 (23.4%) had 3 or more comorbidities. Among singleton livebirths, 206 539 mothers (9.9%) had an ED visit within 90 days before the index pregnancy. ED use in the first year of life was higher among infants whose mother had visited the ED before pregnancy (570 per 1000) vs those whose mother had not (388 per 1000) (RR, 1.19 [95% CI, 1.18-1.20]; ARD, 91.1 per 1000 [95% CI, 88.6-93.6 per 1000]). Compared with mothers without a prepregnancy ED visit, the RR of infant ED use in the first year was 1.19 (95% CI, 1.18-1.20) if its mother had 1 prepregnancy ED visit, 1.18 (95% CI, 1.17-1.20) following 2 visits, and 1.22 (95% CI, 1.20-1.23) after at least 3 maternal visits. A low-acuity maternal prepregnancy ED visit was associated with an adjusted odds ratio (aOR) of 5.52 (95% CI, 5.16-5.90) for a low-acuity infant ED visit, which was numerically higher than the pairing of a high-acuity ED use between mother and infant (aOR, 1.43, 95% CI, 1.38-1.49).Conclusions and relevanceIn this cohort study of singleton livebirths, prepregnancy maternal ED use was associated with a higher rate of ED use by the infant in the first year of life, especially for low-acuity ED use. This study's results may suggest a useful trigger for health system interventions aimed at reducing some ED use in infancy.

Project description:This first Guideline for Reasonable and Appropriate Care in the Emergency Department (GRACE-1) from the Society for Academic Emergency Medicine is on the topic: Recurrent, Low-risk Chest Pain in the Emergency Department. The multidisciplinary guideline panel used The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to assess the certainty of evidence and strength of recommendations regarding eight priority questions for adult patients with recurrent, low-risk chest pain and have derived the following evidence based recommendations: (1) for those >3 h chest pain duration we suggest a single, high-sensitivity troponin below a validated threshold to reasonably exclude acute coronary syndrome (ACS) within 30 days; (2) for those with a normal stress test within the previous 12 months, we do not recommend repeat routine stress testing as a means to decrease rates of major adverse cardiac events at 30 days; (3) insufficient evidence to recommend hospitalization (either standard inpatient admission or observation stay) versus discharge as a strategy to mitigate major adverse cardiac events within 30 days; (4) for those with non-obstructive (<50% stenosis) coronary artery disease (CAD) on prior angiography within 5 years, we suggest referral for expedited outpatient testing as warranted rather than admission for inpatient evaluation; (5) for those with no occlusive CAD (0% stenosis) on prior angiography within 5 years, we recommend referral for expedited outpatient testing as warranted rather than admission for inpatient evaluation; (6) for those with a prior coronary computed tomographic angiography within the past 2 years with no coronary stenosis, we suggest no further diagnostic testing other than a single, normal high-sensitivity troponin below a validated threshold to exclude ACS within that 2 year time frame; (7) we suggest the use of depression and anxiety screening tools as these might have an effect on healthcare use and return emergency department (ED) visits; and (8) we suggest referral for anxiety or depression management, as this might have an impact on healthcare use and return ED visits.
