Evaluation of density variations to determine impact on sterile compounding
PURPOSE: To determine the density variation between (1) the measured density and manually calculated density, (2) density variation of different lots, and (3) density variation of different drug manufacturers in order to support institutions using gravimetric compounding methods.
SUMMARY: Seventeen sterile injectable ingredient (drug) vials frequently used to make compounded sterile products (CSPs) were identified based on the ability to ensure that for each drug there were vials produced by 2 different manufacturers and 2 lots produced by the same manufacturer. Each drug\u27s density was measured using a density meter and by manual calculation using the institution\u27s density formula. Density differences were compared between the 2 different methods. Overall, the average drug density difference between the measured versus calculated density was determined to be 0.022. Further analysis revealed the average difference between the different lot numbers of the same manufacturers was 0.005 for the nonhazardous drugs and 0.0001 for the hazardous drugs. The average difference between the different manufacturers of the same drug was determined to be 0.008 for the nonhazardous drugs and 0.001 for hazardous drugs.
CONCLUSION: No clinically meaningful difference exists when manually calculating a drug\u27s density compared to measuring a drug\u27s density using a density meter. In addition, there does not appear to be a sizeable density variation between the same drugs in separate lots or produced by different manufacturers
Multicenter study to evaluate the benefits of technology-assisted workflow on i.v. room efficiency, costs, and safety.
PURPOSE: The benefits of technology-assisted workflow (TAWF) compared with manual workflow (non-TAWF) on i.v. room efficiency, costs, and safety at hospitals with more than 200 beds are evaluated.
METHODS: Eight hospitals across the United States (4 with TAWF, 4 without) were evaluated, and the characteristics of medication errors and frequency of each error type were measured across the different institutions. The average turnaround time per workflow step and the cost to prepare each compounded sterile preparation (CSP) were also calculated, using descriptive statistics.
RESULTS: The TAWF hospital sites detected errors at a significantly higher rate (3.13%) than the non-TAWF hospital sites (0.22%) (p \u3c 0.05). The top error reporting category for the TAWF sites was incorrect medication (63.30%), while the top error reporting category for the non-TAWF sites was incorrect medication volume (18.34%). Use of TAWF was associated with a preparation time decrease of 2.82 min/CSP, a compounding time decrease of 2.94 min/CSP, and a decrease in overall cost to prepare of $1.60/CSP.
CONCLUSION: The use of TAWF in the i.v. room was associated with the detection of 14 times more errors than the use of non-TAWF, demonstrating different frequency of error in the results. TAWF also led to a faster preparation time that had a lower cost for preparation
