PURPOSE To evaluate the physical and chemical compatibilities of treprostinil sodium and dopamine hydrochloride. METHODS Treprostinil sodium (4,000, 76,000, and 500,000 ng/mL) were mixed with dopamine hydrochloride (0.6, 3.2, 6, and 40 mg/mL). Samples were obtained at hours 0, 1, 2, and 4 for physical compatibility and chemical stability testing. Physical compatibility was assessed by visual examination and measurements of turbidity and pH. Drug concentrations were assessed using stability-indicating liquid chromatography mass spectrophotometry (LCMS) for treprostinil sodium and stability-indicating high-performance liquid chromatography (HPLC) for dopamine hydrochloride. RESULTS Treprostinil sodium 4,000 and 76,000 ng/mL, when mixed with dopamine hydrochloride 0.6, 3.2, 6, and 40 mg/mL, were stable for 4 hours. Treprostinil sodium 500,000 ng/mL was stable when mixed with dopamine hydrochloride 0.6 mg/mL for 4 hours, but when mixed with dopamine hydrochloride 3.2, 6, and 40 mg/mL, significant precipitation was seen. CONCLUSION Treprostinil sodium 4,000 and 76,000 ng/mL were stable for 4 hours during simulated Y-site coadministration with dopamine hydrochloride 0.6, 3.2, 6, and 40 mg/mL. Treprostinil sodium 500,000 ng/mL is stable when mixed with dopamine hydrochloride 0.6 mg/mL. © American Society of Health-System Pharmacists 2020. All rights reserved.

METHODS MAID and a 48-hour time-out were implemented on February 14, 2017. Antibiotic days of therapy (DOT) per 1,000 patient days were compared between the pre- and postperiod for select antibiotics using unadjusted Poisson models. A prepost comparison was used to compare antimicrobial stewardship program (ASP) intervention rates between time periods. A 2-step process, including distribution of a discontinuation (DC) report to pharmacists and ASP-prompted reorders, was instituted to reduce unintentional antimicrobial discontinuation with MAID. ASP-prompted reorders occurred only when a discrepancy persisted between the order and provider-desired duration. Missed antimicrobial doses were identified by ASP and the institutional event reporting system. Safety of MAID was assessed by reviewing the rate and details of ASP-prompted reorders and missed antimicrobial doses. RESULTS A significant decrease in DOT per 1,000 patient days was observed for cefazolin (39.7 to 36.9; P less then 0.001), ampicillin (39.9 to 35.7; P less then 0.001), clindamycin (38.2 to 35.9; P less then 0.001), ceftriaxone (46.5 to 43.4; P less then 0.001), and meropenem (8.7 to 6.6; P less then 0.001) following implementation. No change in ASP intervention rate occurred between the pre- and postperiod (16.9 vs 16.8%; P = 0.94). With MAID, ASP-prompted reorder occurred on 7.3% of orders. Unintentional discontinuations resulting in missed antimicrobial doses occurred in 3 orders (0.07%); no patient harm resulted. CONCLUSION MAID and a 48-hour time-out significantly reduced DOT of select antibiotics. No patient harm occurred with the 2-step safety process. © American Society of Health-System Pharmacists 2020.

The purpose of this study was to determine the current state of PCT monitoring at community hospitals across the United States. METHODS Data from adult patients who were admitted to community hospitals affiliated with a large healthcare system between August 1, 2016, and July 31, 2017, and who received antibiotics were evaluated for the number of PCT levels drawn and the timing between multiple levels. Data from eligible patients were evaluated for the discontinuation of antibiotics after meeting prespecified PCT thresholds for discontinuation of therapy, namely, a PCT measurement of less then 0.5 μg/L or a decrease of ≥80% from a previous peak value. RESULTS PCT levels were evaluated for 103,913 patient data sets collected from 136 hospitals. Of these, 70% of the data sets showed a single PCT level drawn, and approximately 30% (30,887) of the data sets showed multiple levels drawn. The first PCT measurement was drawn within 36 hours of antibiotic initiation in 96% of the patients. Of those with multiple levels, 23% (7,089) had levels drawn 24 to 72 hours apart. click here A small proportion (20% [6,127]) of the patients with multiple levels were eligible for evaluation of appropriate antibiotic discontinuation. Of these, 1,973 (32.2%) patients had antibiotics discontinued within 36 hours of meeting the prespecified PCT thresholds; these patients had a mean duration of antibiotic therapy of 6.1 days with a median of 4.7. CONCLUSION Additional standardization of ongoing PCT monitoring and education regarding the appropriate discontinuation of antibiotics when thresholds are reached could aid in the use of this biomarker in support of antibiotic and laboratory stewardship. © American Society of Health-System Pharmacists 2020.

Recent advances in neurosurgical care, however, have demonstrated that these patients not only can survive, but they also can recover functionally when they undergo appropriate cerebral decompression within hours of injury. At the present, general surgeons are deployed further forward than neurosurgeons (Role 2 compared to Role 3) and have been provided with guidelines that stipulate conditions where they may have to perform decompressive craniectomies. Unfortunately, Role 2 medical facilities do not have access to computed tomography imaging or intracranial pressure monitoring capabilities rendering the decision to proceed with craniectomy based solely on exam findings. Utilizing a case transferred from downrange to our institution, we demonstrate the utility of a small, highly portable quantitative pupillometer to obtain reliable and reproducible data about a patient's intracranial pressures. Following the case presentation, the literature supporting quantitative pupillometry for surgical decision-making is reviewed.
