Implementation of EMR-based standardized antibiotic desensitization protocols and its impact on providers

Background: As desensitization protocols become more readily available and published, more institutions are implementing them and searching for ways to streamline the process. There have been no published studies to date on the effect that electronic medical record systems (EMR) have on the safety and efficiency of β-lactam antibiotic desensitization. Objective: The purpose of this study was to evaluate the changes in workflow, efficiency, and medical errors after implementation of β-lactam antibiotic desensitization. Methods: A collaborative effort between the Allergy/Immunology Division and the Pharmacy Department led to the creation and implementation of antibiotic desensitization order sets. Pre- and postimplementation of β-lactam antibiotic surveys were sent to pharmacists and allergy/immunology fellows and attendings at a single-center tertiary care center. Results: There were only 26 valid respondents (12.3%) to both the pre- and postimplementation surveys. The percentage of respondents who thought that the time needed to prepare desensitization materials was < 4 hours increased from 23% to 77% (p < 0.001). The percentage of respondents who thought that the time needed to input electronic desensitization orders was < 1 hour increased from 19% to 54% (p = 0.002). The percentage of respondents who identified zero errors increased from 42% to 92% (p = 0.001). The perception of the overall desensitization process efficiency significantly increased (p < 0.001). Conclusion: Creation of standardized electronic β-lactam antibiotic desensitization order sets significantly decreased the time taken to order and prepare materials and increased overall efficiency.
