Summary
Accurate medication reconciliation is challenging due to data entry errors in anesthesia information management systems (AIMS) and dispensing systems. Improving electronic interfaces could reduce these discrepancies and associated costs.
Area of Science:
- Anesthesiology
- Health Informatics
- Pharmacy Practice
Background:
- Regulatory agencies mandate precise tracking of controlled substance disposal.
- Integrating anesthesia information management systems (AIMS) with medication dispensing systems offers potential for automated discrepancy reconciliation.
Purpose of the Study:
- To evaluate the accuracy of medication records by comparing dispensed versus administered medications.
- To identify the types and sources of discrepancies between AIMS and medication dispensing systems.
Main Methods:
- A retrospective review of 11,603 cases was conducted over an 8-month period at a large academic hospital.
- Medications recorded as removed from automated dispensing systems were compared with those recorded as administered in the AIMS.
Main Results:
- Fifteen percent of cases exhibited discrepancies between dispensed and administered medications.
- Errors were found in both the AIMS (8%) and the medication dispensing system (10%).
- Approximately 75% of errors stemmed from incorrect documentation of drug waste or medication administration in the respective systems.
Conclusions:
- Significant data entry errors exist in both automated dispensing and AIMS, hindering automated reconciliation.
- An electronic interface could proactively alert users to errors, reducing reconciliation time and costs.

01:30Methods of Documentation VII: EMR
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare settings,...

01:10Documentation of Nursing Diagnosis
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters assessment...

01:26Pharmaceutical Poisoning: Potential Scenarios
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...
01:22Pharmaceutical Alternatives: Stability-Related Therapeutic Nonequivalence
Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery. A 3 g dose typically provides...
