In a survey of adult hospital providers regarding antibiotic use in the treatment of febrile neutropenia, clinical fellows, and pharmacists showed higher comfort levels with early antimicrobial de-escalation compared to hematology-oncology and transplant infectious diseases physicians. These frontline team members are ideal partners to champion antimicrobial stewardship interventions in febrile neutropenia.
Background: Self-reported antibiotic allergies, also known as antibiotic allergy labels, are common and may lead to worse patient outcomes. Within immunocompromized patients, antibiotic allergy labels can lead to inappropriate use of antimicrobials and may limit options for prophylactic and therapeutic options in the posttransplant period.While antibiotic allergy delabeling is considered an important aspect of antibiotic stewardship protocols, evidence and awareness of its application in transplant recipients is limited.
Methods:We describe our experience with an antibiotic allergy delabeling intervention in the pretransplant evaluation period and its impact on posttransplant antimicrobial utilization. This was a retrospective analysis of patients with an antibiotic allergy label who underwent evaluation for solid organ or stem cell transplantation between 2015 and 2020. Patients included in this analysis were those who completed pretransplant antibiotic allergy delabeling through our Drug Allergy Clinic and were retained in care for 6 months after transplant.Results: Twenty-six of 27 patients underwent pretransplant antibiotic allergy delabeling and safely received the delabeled antibiotic posttransplant. There were no reported side effects to the delabeled antibiotic within 6 months posttransplant. Specific examination of sulfonamide (sulfa)-antibiotic delabeling showed cost savings of $254 to $2910 per patient in the posttransplant period compared to the use of alternative antibiotics for prophylaxis protocol.
Conclusion:Antibiotic allergy delabeling prior to transplant is safe, is of high value, and should be considered in the pretransplant evaluation period. More resources are needed for the development of delabeling guidelines and support for broad implementation of pretransplant antibiotic allergy delabeling programs.
Objective:
To design and implement “handshake rounds” as an antibiotic stewardship intervention to reduce inpatient intravenous (IV) antibiotic use in patients with hematologic malignancies.
Design:
Quasi-experimental analysis of antibiotic use (AU) and secondary outcomes before and and after handshake rounds were implemented.
Setting:
Quaternary-care, academic medical center.
Patients:
Hospitalized adults with hematologic malignancies receiving IV antibiotics.
Methods:
We performed a retrospective review of a preintervention cohort prior to the intervention. A multidisciplinary team developed criteria for de-escalation of antibiotics, logistics of handshake rounds, and outcome metrics. Eligible patients were discussed during scheduled handshake rounds between a hematology–oncology pharmacist and transplant–infectious diseases (TID) physician. Prospective data were collected over 30 days in the postintervention cohort. Due to small sample size, 2:1 matching was used to compare pre- to and postintervention AU. Total AU in days of therapy per 1,000 patient days (DOT/1,000 PD) was reported. Mean AU per patient was analyzed using Wilcoxon rank-sum test. A descriptive analysis of secondary outcomes of pre- and postintervention cohorts was performed.
Results:
Total AU was substantially lower after the intervention, with 517 DOT/1,000 PD compared to 865 DOT/1,000 PD before the intervention. There was no statistically significant difference in the mean AU per patient between the 2 cohorts. There was a lower rate of 30-day mortality in the postintervention cohort and rates of ICU admissions were similar.
Conclusions:
Conducting handshake rounds is a safe and effective way to implement an antibiotic stewardship intervention among high-risk patient population such as those with hematologic malignancies.
Transplant infectious diseases is an engaging subspecialty within the field of infectious diseases and poses unique considerations when searching for a job. Here, we present essential considerations for those early in their career when applying for and selecting their employment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
