DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: In high-acuity situations such as cardiac arrest, clinicians rely on prepared medications stocked in code carts to provide timely and accurate pharmacotherapy. We examined shortage trends for medications commonly used in code carts. METHODS: Drug shortage data from 2001 to 2022 were retrieved from the University of Utah Drug Information Service (UUDIS) to characterize shortages reported for commonly used code cart medications. Data extracted included the number of shortages, shortage duration, drug characteristics, and reason for the shortage. RESULTS: From 2001 to 2022, 71 drug shortages for code cart medications were reported. The number of new shortages peaked in 2010, and the number of total shortages peaked in 2010. At the end of the study period, 61 (84.7%) shortages had been resolved. For resolved shortages, the mean shortage duration was 18.2 months. The drug with the greatest number of reported shortages was dextrose (10 total), the drug with the longest resolved shortage was calcium chloride injection (116 months), and the drug with the longest active shortage was atropine injection (165 months at the end of the study period). Throughout the entire study period, only 2 suppliers provided commercially available prefilled syringes of dextrose for stocking on code carts. The most common reason for shortages, when reported, was manufacturing delays. CONCLUSION: Medications commonly used in code carts were frequently impacted by drug shortages, which have the potential to impact patient care. Institutional protocols for mitigation and larger efforts to promote a more resilient drug supply chain are critical to ensure patient safety and quality care.
RESUMEN
PURPOSE: Cardiopulmonary resuscitation is common in the United States, with >200,000 people experiencing an in-hospital cardiac arrest (IHCA) annually. Recent medication shortages have raised the question of the frequency and type of medication used during cardiac arrest resuscitation. We sought to determine the frequency and quantity of medications used during IHCA. METHODS: This retrospective, single-center, medical record review was performed at a large, urban teaching hospital. Adults ≥18 years old who had an IHCA with confirmed loss of pulse between January 2017 and March 2018 were identified. A standardized data collection tool was used to extract data from the electronic medical record. The primary outcome was the frequency and quantity of medications used during the IHCA. Secondary outcomes included median time to defibrillation and frequency of sodium bicarbonate use, including among patients with end-stage renal disease (ESRD). FINDINGS: Criteria were met for 181 IHCA events. Demographic characteristics were 71% black, 17% white, mean age of 65 years, and 46% women. Epinephrine was given in 86.7% of the arrests, with a mean cumulative dose of 4.2 mg. Sodium bicarbonate was given in 63.5% of the arrests, with a mean cumulative dose of 9.0 g (1.9 amps). Amiodarone was given in 30.9% of the arrests, with a mean cumulative dose of 311.8 mg. Median time to defibrillation was 2 min (interquartile range, 1-4 min). Preexisting ESRD was present in 24.8% of patients, of whom 71.1% received sodium bicarbonate. Sodium bicarbonate administration was associated with a lower likelihood of survival to discharge (odds ratio [OR] = 0.27; 95% CI, 0.11-0.66) as well as a lower rate of return to spontaneous circulation (ROSC) (OR = 0.35; 95% CI, 0.13-0.95). Magnesium administration was associated with a lower rate of ROSC (OR = 0.39; 95% CI, 0.15-0.98). Of note, in patients with preexisting ESRD, no medications were significantly associated with a change in likelihood of survival to discharge or rate of ROSC. In patients without preexisting ESRD, magnesium was associated with a lower rate of ROSC (OR = 0.23; 95% CI, 0.08-0.77). IMPLICATIONS: We found that in a hospital with established rapid response and code blue teams, numerous medications that are not recommended for routine use in cardiac arrest are still administered at significant frequencies. Furthermore, substantial amounts of drugs with known recent shortage are used in IHCA. Inc.
