2055. Action: A Year in the Lives of Consultant Pharmacists Working on Antimicrobial Stewardship in Long-Term Care Facilities

BACKGROUND: The CDC recommends consultant pharmacists (CP) support antimicrobial stewardship (AS) activities in long-term care facilities (LTCF) by reviewing antimicrobial appropriateness. We initiated a project training CP from a regional long-term care pharmacy to support AS implementation in LTCF. METHODS: CP were trained to evaluate the appropriateness of all systemic antimicrobial therapy (AT) and provide prescriber feedback during their monthly drug regimen review (DRR). An electronic database was developed to facilitate data reporting. Antimicrobial use (AU) and adverse events (AE) from 32 LTCF were analyzed for 2018 using descriptive statistics. RESULTS: A total of 5327 courses of AT with a median duration of 7 days (IQR 5–10) were reviewed. The majority of AT was started in the LTCF (55%) but was also initiated in hospitals (24%), clinics (11%) and emergency departments (2%). Of 2926 AT started in LTCF, 36% were based on nurse evaluation (NE) while 33% began after prescriber evaluation (PE). Fluoroquinolones (FQ) and first-generation cephalosporins were the most commonly prescribed agents (Table 1). Treatment or prophylaxis of urinary tract infections accounted for 40% of AU (Figure 1). Diagnostic testing was associated with 37% of AT courses. Urine cultures were the most frequent test performed (81%). Overall, 41% of AT was determined to be inappropriate resulting in > 800 feedback letters sent to prescribers. Unnecessary antibiotic starts (based on revised Mc Geer or Loeb’s criteria) were identified as the most common reason (Figure 2). AT appropriateness varied depending on the setting in which it was initiated. A majority (87%) of AT initiated in hospitals was found to be appropriate with 56% and 46% appropriate for ED and clinic starts. Appropriateness of LTCF initiated AT was 49% (59% after PE and 42% after NE). AE were associated with 3% of AT with allergic reactions and Clostridioides difficile infections occurring with 0.4% and 0.7% of AT, respectively. AE were most frequently associated with folate antagonists (5%) and FQ (3%). CONCLUSION: This study demonstrates many AU improvement opportunities exist in LTCF and CP can play an important role in identifying them if trained in AS principles. CP should review all AU for appropriateness and provide data to inform AS efforts in LTCF. [Image: see text] [Image: see text] [Image: see text] DISCLOSURES: All authors: No reported disclosures.
