RESUMEN
Background: Given the negative consequences associated with a penicillin allergy label, broader penicillin allergy delabeling initiatives are highly desirable but hindered by the shortage of allergists in the United States. To address this problem at our facility, the infectious diseases section introduced a quality improvement initiative to evaluate and remove allergy labels among inpatient veterans. Methods: Between 15 November 2022 and 15 December 2023, we identified inpatients with a penicillin allergy label. We subsequently interviewed eligible candidates to stratify penicillin allergy risk and attempt to remove the allergy label directly via chart review, following inpatient oral amoxicillin challenge or outpatient community care allergy referral. Delabeling outcomes, subsequent penicillin-class prescriptions, and relabeling were tracked after successful allergy label removal. Results: We screened 272 veterans, of whom 154 were interviewed for this intervention. A total of 53 patients were delabeled: 26 directly, 23 following oral amoxicillin challenge, and 4 following outpatient allergy referrals. Of the patients who were delabeled, 25 received subsequent penicillin-class prescriptions. No adverse reactions occurred following inpatient oral amoxicillin challenges. Patients with a low-risk penicillin allergy history were more likely to undergo a challenge if admitted with an infectious diseases-related condition. Only 1 inappropriate relabeling event occurred during the study period, which was subsequently corrected. Conclusions: An infectious diseases provider-led initiative resulted in penicillin allergy label removal in more than one third of inpatients evaluated using direct removal or oral amoxicillin challenge. Efforts focused on patients who had been admitted for infections were particularly successful.
RESUMEN
We retrospectively reviewed the records of 136 veterans with a penicillin allergy label during a quality improvement initiative. We identified 82 inpatients eligible for removal of penicillin allergy by oral amoxicillin challenge, including 40 out of 82 (48%) still eligible after accounting for other limiting factors.
RESUMEN
The presence of a penicillin allergy label in a patient's medical chart is associated with negative clinical and economic outcomes. Given that less than 10% of reported reactions are truly immunoglobulin E-mediated, removal of unverified penicillin allergy labels is a public health priority and an area of ongoing implementation research. The Veterans Health Administration (VHA) is the largest integrated healthcare system in the United States, with almost 9 million veterans currently enrolled. However, studies analyzing the impact of the penicillin allergy label in this population are limited to single facilities and largely focus on short-term outcomes of allergy documentation correction, usage of ß-lactams, and avoidance of antibiotic-related side effects. Broader, national VHA studies focusing on health outcomes and costs are lacking. As with non-VHA facilities, penicillin allergy evaluations are limited owing to the absence of formal allergy/immunology services at most VHA facilities. Pharmacy-driven screening and referral for clinic-based penicillin skin testing is a promising and frequently discussed modality in the literature, but its scalability within the VHA is not yet proven. Broader, evidence-based strategies that can be adapted to the available resources of individual VHA facilities, including those without on-site access to allergy providers, are needed.
RESUMEN
An outpatient parenteral antimicrobial therapy team from a Veterans Affairs facility managed patients discharged from their own facility and neighboring community hospitals. There were no significant differences in adverse outcomes between the groups, but a majority of regimens were modified from those initially proposed by community providers.
RESUMEN
Background: Accurate and timely prescriptions of COVID-19 therapeutics, laboratory testing, and antimicrobial stewardship have been a challenge throughout the pandemic as new evidence emerges. While universal consultation with infectious disease specialists on patients admitted with COVID-19 is desirable, it is not always feasible due to limited resources. Observations: In this single-center study, we implemented a combined educational and laboratory stewardship intervention geared toward hospitalist practitioners resulting in improved accuracy of remdesivir and dexamethasone prescriptions, reduced laboratory use of blood cultures, interleukin 6 assay, and Legionella sputum cultures, and a decrease in antibiotic use for patients with mild-to-moderate oxygen requirements over 6 months. These improvements were seen in tandem with decreased reliance on infectious disease consultation. Conclusions: These efforts support proof of the principle of combined educational and laboratory stewardship interventions to improve the care of COVID-19 patients, especially where infectious disease consultation may not be available or is accessed remotely.
RESUMEN
We report a case of cervical blastomycosis with associated paravertebral involvement and severe spinal canal stenosis in a 48-year-old patient presenting with acute airway obstruction from a retropharyngeal abscess. Our case was also complicated by severe hypokalemia that developed during the blastomycosis treatment course with posaconazole and which improved after discontinuation and replacement therapy. After 12 months of blastomycosis-targeted therapy, our patient had complete resolution of clinical, laboratory, and radiological findings of blastomycosis.
RESUMEN
BACKGROUND: Antimicrobial stewardship has been promoted as a key strategy for coping with the problems of antimicrobial resistance and Clostridium difficile. Despite the current call for stewardship in community hospitals, including smaller community hospitals, practical examples of stewardship programs are scarce in the reported literature. The purpose of the current report is to describe the implementation of an antimicrobial stewardship program on the medical-surgical service of a 100-bed community hospital employing a core strategy of post-prescriptive audit with intervention and feedback. METHODS: For one hour twice weekly, an infectious diseases physician and a clinical pharmacist audited medical records of inpatients receiving systemic antimicrobial therapy and made non-binding, written recommendations that were subsequently scored for implementation. Defined daily doses (DDDs; World Health Organization Center for Drug Statistics Methodology) and acquisition costs per admission and per patient-day were calculated monthly for all administered antimicrobial agents. RESULTS: The antimicrobial stewardship team (AST) made one or more recommendations for 313 of 367 audits during a 16-month intervention period (September 2009 - December 2010). Physicians implemented recommendation(s) from each of 234 (75%) audits, including from 85 of 115 for which discontinuation of all antimicrobial therapy was recommended. In comparison to an 8-month baseline period (January 2009 - August 2009), there was a 22% decrease in defined daily doses per 100 admissions (P = .006) and a 16% reduction per 1000 patient-days (P = .013). There was a 32% reduction in antimicrobial acquisition cost per admission (P = .013) and a 25% acquisition cost reduction per patient-day (P = .022). CONCLUSIONS: An effective antimicrobial stewardship program was implemented with limited resources on the medical-surgical service of a 100-bed community hospital.
RESUMEN
We implemented an antimicrobial stewardship program at an urban, 60-bed long-term acute care hospital using a strategy of weekly postprescriptive chart audit with intervention and feedback. The results for the first 15 months demonstrated 80% acceptance of recommendations, a 21% reduction in use, and a 28% reduction in cost per patient-day.
