A Multidisciplinary Quality Improvement Initiative to Facilitate Penicillin Allergy Delabeling Among Hospitalized Pediatric Patients.

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.

Long-Term Impact of a Clinical Care Guideline for Pediatric Acute Musculoskeletal Infections: Are Improved Outcomes Sustainable?

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.
