The scope of this problem is daunting since an estimated 90% of hospitalized patients receive medication via the IV route

Our findings challenge the dogma that expertise is synonymous with seniority, and they highlight the distinction between recent practice and cumulative experience.

PATIENT CAREGIVER FINANCIAL
PATIENT CAREGIVER FINANCIAL
Preventable ADEs from injectable medications were estimated to occur in 1.2 million inpatient hospitalizations annually in the United States
Example: Eric Cropp. Involved in a compounding error that took the life of 2 year old Emily Jerry 2006. Lost job, lost license, received a fine, and was ultimately sentenced to prison.
According to data from Bates 1997 study, cost can add more than $5000 to the cost of a hospital stay Estimated inpatient preventable ADEs associated with injectable medications increase the annual US payer costs by $2.7 - $5.1 billion

Everyone commits errors
Human error is generally the result of circumstances beyond the control of those committing the errors
Systems or processes that depend on perfect human performance are inherently flawed
Classification of Errors
Skill-based errors – slips and lapses
Knowledge-based mistakes

Bottom line
There is nothing in the current USP General Chapters or other U.S. regulatory documentation that directly addresses the use of automation and
technology during the sterile compounding process or their use inside the hood.
Automated compounding device and balance
The automated compounding device (ACD) must be positioned in the C-PEC such that compounding occurs while critical sites are exposed to first air.
The ACD must be calibrated at least once a day, then as needed…
The balance must be calibrated before each use, after it is moved, after disinfecting and as needed…
The results of calibration must be documented
Model Standards for Pharmacy Compounding Sterile Preparations Approved by the NAPRA Board of Directors April 2015, published September 2016
Camera and computer equipment
Audio-visual and computer equipment* used for verification during compounding is allowed in the clean room under certain conditions. Preference must be given to audiovisual and computer equipment that features “hands-free” operation and that is made of smooth, nonporous, cleanable materials with low particulate emission and resistance to damage from cleaning and disinfecting products.
Model Standards for Pharmacy Compounding Sterile Preparations Approved by the NAPRA Board of Directors April 2015, published September 2016 *camera, monitor, pedal system
One of the advantages of technology is that it can enhance human performance to the extent that the human plus technology is more powerful than either is alone.

“The American Society of Health‐System Pharmacists encourages hospital and health‐system pharmacies to incorporate bar‐code scanning into inventory management, dose preparation and packaging, and dispensing of medications.”

“Now is the time for hospital leadership to support the acquisition of IV workflow technologies that utilize barcode scanning of products during pharmacy IV admixture preparation. Systems … that utilize barcode scanning support can assure proper drug selection….”

Technician production time ↓ by 34%
Pharmacist checking time ↓ by 37%
Labor savings estimated at $158,000 annually
Decreased waste
Pros Utilized in analytical chemistry because it is extremely accurate.
Serves as a forcing function, in that preparers cannot proceed to next steps without scales having confirmed volumes in previous steps
Prevents upstream errors in the preparation process
Cons Volumetrics generally considered as accurate as gravimetrics
Additional time-consuming steps of weighing each item before and after drawing and injecting liquids.
Sensitive to air movement in PECs, requiring time to settle and register weights of products placed on them.
