BACKGROUND: Penicillin allergy is reported in up to 10% of the general population; however, .90% of patients reporting an allergy are tolerant. Patients labeled as penicillin allergic have longer hospital stays, increased exposure to suboptimal antibiotics, and an increased risk of methicillin-resistant Staphylococcus aureus and Clostridioides difficile. The primary aim with our quality improvement initiative was to increase penicillin allergy delabeling to at least 10% among all hospitalized pediatric patients reporting a penicillin allergy with efforts directed toward patients determined to be low risk for true allergic reaction.METHODS: Our quality improvement project included several interventions: the development of a multidisciplinary clinical care pathway to identify eligible patients, workflow optimization to support delabeling, an educational intervention, and participation in our institution's quality improvement incentive program. Our interventions were targeted to facilitate appropriate delabeling by the primary hospital medicine team. Statistical process control charts were used to assess the impact of this intervention pre-and postpathway implementation.RESULTS: After implementation of the clinical pathway, the percentage of patients admitted to hospital medicine delabeled of their penicillin allergy by discharge increased to 11.7%. More than one-half of those delabeled (51.2%) received a penicillin-based antimicrobial at time of discharge. There have been no adverse events or allergic reactions requiring emergency medication administration since pathway implementation.CONCLUSIONS: Our quality improvement initiative successfully increased the rate of penicillin allergy delabeling among low-risk hospitalized pediatric patients, allowing for increased use of optimal antibiotics.

BACKGROUND: Acute hematogenous musculoskeletal infections are a common cause of hospitalization in children. A locally developed clinical care guideline (CCG) for acute musculoskeletal infections was implemented at our quaternary care pediatric hospital in July 2012. The purpose of this study was to evaluate the long-term sustainability of previously described improvements after CCG implementation. METHODS: Clinical outcomes for children hospitalized with musculoskeletal infections at Children’s Hospital Colorado from June 2009 through September 2018 were retrospectively reviewed. Patients were included if they had an International Classification of Diseases, Ninth Revision or International Classification of Diseases, 10th Revision discharge diagnosis of acute osteomyelitis, septic arthritis, or pyomyositis and were between 6 months and 18 years of age at admission. Patients with underlying medical complexity or nonhematogenous musculoskeletal infections were excluded. Patients were categorized by date of admission as either “pre-CCG” (June 2009 to June 2011) or “sustain-CCG” (July 2014 to September 2018). Primary outcomes were hospital length of stay and intravenous antimicrobial length of therapy. RESULTS: From pre-CCG to sustain-CCG, median length of stay decreased by 1.29 days (5.56 vs 4.27; P < .004) and median length of therapy decreased by 5.04 days (8.33 vs 3.29; P < .0001). Statistical process control charts support that these were sustained improvements many years after CCG implementation. Additional secondary clinical improvements were observed in the sustain-CCG group including faster fever resolution, more consistent blood and source culture acquisition, and decreased central line placement. There was no increase in related readmissions or therapeutic failures in the sustain-CCG group. CONCLUSIONS: Implementation of a CCG to standardize care for musculoskeletal infections can be sustained many years after implementation.

ObjectivesFew studies describe the impact of antimicrobial stewardship programs (ASPs) on recognizing and preventing diagnostic errors. Handshake stewardship (HS-ASP) is a novel ASP model that prospectively reviews hospital-wide antimicrobial usage with recommendations made in person to treatment teams. The purpose of this study was to determine if HS-ASP could identify and intervene on potential diagnostic errors for children hospitalized at a quaternary care children’s hospital.MethodsPreviously self-identified “Great Catch” (GC) interventions by the Children’s Hospital Colorado HS-ASP team from 10/2014 through 5/2018 were retrospectively reviewed. Each GC was categorized based on the types of recommendations from HS-ASP, including if any diagnostic recommendations were made to the treatment team. Each GC was independently scored using the “Safer Dx Instrument” to determine presence of diagnostic error based on a previously determined cut-off score of ≤1.50. Interrater reliability for the instrument was measured using a randomized subset of one third of GCs.ResultsDuring the study period, there were 162 GC interventions. Of these, 65 (40%) included diagnostic recommendations by HS-ASP and 19 (12%) had a Safer Dx Score of ≤1.50, (Κ=0.44; moderate agreement). Of those GCs associated with diagnostic errors, the HS-ASP team made a diagnostic recommendation to the primary treatment team 95% of the time.ConclusionsHandshake stewardship has the potential to identify and intervene on diagnostic errors for hospitalized children.

Background Over 90% of children with reported penicillin allergy can tolerate penicillin without incident. Developing effective and safe strategies to remove inappropriate penicillin allergies has the potential to improve care; however, guidance on how to identify, test, and delabel patients is limited. Methods In April 2019, Children’s Hospital Colorado (CHCO) implemented a penicillin allergy clinical pathway (CP) alongside a risk assessment tool to stratify patients based on allergic history (Figure 1). Patients at “no increased risk” were educated and delabeled without testing. Low risk patients were offered an oral amoxicillin drug challenge with close observation. A single, non-graded, treatment dose of amoxicillin (45 mg/kg, max dose 1000mg) was used for low risk patients, and no preceding allergic skin testing was performed. Patients with no signs or symptoms of allergic response 60 minutes after amoxicillin administration were delabeled. Children delabeled of penicillin allergies on the CHCO hospital medicine service were compared between the pre-CP (1/1/17-3/31/19) and post-CP (4/1/19-3/31/20) cohorts. Figure 1. Penicillin Allergy Risk Assessment Results Pre-CP, 683/10624 (6.4%) patients reported a penicillin allergy and 18/683 (2.6%) were delabeled by discharge. Post-CP, 345/6559 (5.3%) patients reported a penicillin allergy and 47/345 (13.6%) were delabeled by discharge (P-value < 0.0001, Figure 2). Among the 47 post-CP patients, 11 were delabeled by history alone, 19 underwent oral amoxicillin drug challenge per CP, and 17 received a different treatment dose penicillin per treatment team. Only one penicillin-exposed patients had a reaction. This patient developed a delayed, non-progressive rash and had penicillin allergy restored to their chart. No patient required emergency medical intervention, and none were “relabeled” penicillin allergic in the 6 months following discharge. Figure 2. Monthly Rate of Penicillin Allergic Patients Delabeled by Discharge Conclusion A drug challenge using a single non-graded dose of oral amoxicillin is a safe and effective strategy to delabel low risk children of inappropriate penicillin allergies when implemented alongside a risk assessment tool. Further studies are needed to evaluate the long-term benefits of delabeling inappropriate penicillin allergies and to continue monitoring for adverse events.
