Privileging pharmacists improves time to patient notification in the microbiological test review process for patients discharged from the emergency department

Abstract

Abstract Purpose Results of a study evaluating the impact of privileging pharmacists to manage microbiologic test results for patients discharged from the emergency department (ED) are reported. Methods This was a single-center, retrospective pre-post study that was conducted at an urban academic medical center. Patients discharged from the ED with a subsequent positive microbiologic test result before and after privileging of an ED specialty practice pharmacist (ED-SPP) to manage the results independently were screened for inclusion. Time to patient notification of a required change in antimicrobial therapy was compared between groups. Numbers of erroneous interventions before and after pharmacist privileging were compared to assess the safety of implementation. Results One hundred seventy-eight positive microbiologic test results (n = 92 pre- and n = 86 postimplementation) were included. The median time to patient notification in the pre-implementation group was 23.6 hours (range, 12.4-93 hours) and in the postimplementation group was 14.9 hours (range, 2.5-27.9 hours; P = 0.0023). As determined by the board-certified infectious disease physician, 1.1% of reviewed microbiologic test results (1 of 92) was erroneous prior to implementation of pharmacist privileging compared with 2.3% (2 of 86) after implementation (P = 0.6105). Conclusion Privileging ED-SPPs to assess microbiologic test results improved the time to patient notification with no statistical difference in the number of erroneous interventions between groups. These findings demonstrate the benefit of clinical privileging and provide support for expansion of this role to other ED-SPPs.
