Risk of Acute Kidney Injury Associated With Medication Administration in the Emergency Department.

BACKGROUND: Patients who develop acute kidney injury (AKI) have a 2-fold increased risk for major adverse events within 1 year. An estimated 19-26% of all cases of hospital-acquired AKI may be attributable to drug-induced kidney disease (DIKD). Patients evaluated in the emergency department (ED) are often prescribed potentially nephrotoxic drugs, yet the role of ED prescribing in DIKD is unknown. OBJECTIVE: We sought to measure the association between ED medication administration and development of AKI. METHODS: This was a retrospective 5-year cohort analysis at a single center. Patients with a serum creatinine measurement at presentation in the ED and 24-168 h later were included. Outcome was incidence of AKI as defined by Kidney Disease Improving Global Outcomes criteria in the 7 days after ED evaluation. Medication administration risk was estimated using Cox proportional hazards model. RESULTS: There were 46,965 ED encounters by 30,407 patients included in the study, of which 6461 (13.8%) patients met the criteria for AKI. For hospitalized patients, administration of a potentially nephrotoxic medication was associated with increased risk of AKI (hazard ratio [HR] 1.30 [95% confidence interval {CI} 1.20-1.41]). Diuretics were associated with the largest risk of AKI (HR 1.64 [95% CI 1.52-1.78]), followed by angiotensin-converting enzyme inhibitors (HR 1.39 [95% CI 1.26-1.54]) and antibiotics (HR 1.13 [95% CI 1.05-1.22]). For discharged patients, administration of antibiotics was strongly associated with increased risk of AKI (HR 3.19 [95% CI 1.08-9.43]). CONCLUSION: ED administration of potentially nephrotoxic medications was associated with an increased risk of AKI in the following 7 days. Diuretics, angiotensin-converting enzyme inhibitors, and antibiotics were independently associated with increased risk of AKI. Nephroprotective practices in the ED may mitigate kidney injury and long-term adverse outcomes.

Development and implementation of procedures for outpatient naloxone prescribing at a large academic medical center.

PURPOSE: An interprofessional initiative to operationalize outpatient naloxone prescribing at a large academic medical center is described. SUMMARY: The initiative was carried out by a work group of clinical pharmacists and pharmacy administrators in collaboration with physicians and nursing staff leaders from multiple practice settings. An opioid overdose risk-assessment guide was developed on the basis of literature review and expert opinion. An institutional policy to guide identification of high-risk patient populations and facilitate naloxone prescribing and dispensing was developed and vetted by multiple expert committees. Patient education materials were created, and patients at high risk for opioid overdose were educated about overdose risk factors and naloxone use by a pharmacist and/or nurse before discharge or, in some cases, by outpatient pharmacists; when feasible, patients' friends, family members, and/or caregivers were included in education sessions. Interventions included distribution of a pamphlet emphasizing the importance of contacting emergency medical services personnel immediately in the event of an overdose, depicting the process for administration of injectable and nasal spray formulations of naloxone, and providing information on other first-response steps. Collaboration with outpatient pharmacies allowed for successful dispensing of naloxone prescriptions. CONCLUSION: The implementation of an outpatient naloxone prescribing policy at a large academic medical center created a streamlined approach for the interprofessional healthcare team to use in providing naloxone education and improved naloxone access to patients at high risk for opioid overdose.
