Medication Errors Involving the Intravenous Administration Route: Characteristics of Voluntarily Reported Medication Errors

Evolution of Intravenous Medication Errors and Preventive Systemic Defenses in Hospital Settings-A Narrative Review of Recent Evidence

OBJECTIVES

Intravenous drug administration has been associated with severe medication errors in hospitals. The present narrative review is based on a systematic literature search, and aimed to describe the recent evolution in research on systemic causes and defenses in intravenous medication errors in hospitals.

METHODS

This narrative review was based on Reason's theory of systems-based risk management. A systematic literature search covering the period from June 2016 to October 2021 was conducted on Medline (Ovid). We used the search strategy and selection criteria developed for our previous systematic reviews. The included articles were analyzed and compared to our previous reviews.

RESULTS

The updated search found 435 articles. Of the 63 included articles, 16 focused on systemic causes of intravenous medication errors, and 47 on systemic defenses. A high proportion (n = 24, 38%) of the studies were conducted in the United States or Canada. Most of the studies focused on drug administration (n = 21/63, 33%) and preparation (n = 19/63, 30%). Compared to our previous review of error causes, more studies (n = 5/16, 31%) utilized research designs with a prospective risk management approach. Within articles related to systemic defenses, smart infusion pumps remained most widely studied (n = 10/47, 21%), while those related to preparation technologies (n = 7/47, 15%) had increased.

CONCLUSIONS

This narrative review demonstrates a growing interest in systems-based risk management for intravenous drug therapy and in introducing new technology, particularly smart infusion pumps and preparation systems, as systemic defenses. When introducing new technologies, prospective assessment and continuous monitoring of emerging safety risks should be conducted.

Labelling of intravenous drug delivery devices in critically ill patients: A scoping review

BACKGROUND

Labelling is a strategy that contributes to the correct and faster identification of drugs, minimizing misidentification. There is a gap in knowledge on optimal labelling standards for intravenous (IV) devices applied to the care of critically ill patients.

AIM

The goal of this article was to map existing knowledge on the labelling of IV drug delivery devices in critically ill patients for the prevention of medication errors.

STUDY DESIGN

This was a scoping review conducted according to the JBI methodology in the LILACS, MEDLINE, CINAHL, IBECS, Scopus, Embase and Web of Science databases, and on the websites of specialized institutions. Searches were conducted up to December 2022 for scientific articles and grey literature that addressed the labelling of IV devices in intensive care units, emergency departments, and anaesthesia units. The data were collected using a structured form and were later classified, summarized, and aggregated to map the knowledge related to the review question.

RESULTS

Twenty-one documents were included, which demonstrated variability in label use with IV drug delivery devices. The following features of structure and design stood out: printed format, colour coding, letter size differentiation, and the use of sturdy material. In terms of information, the name of the drug, dose, date and time of preparation, identification of the patient, and who prepared it were found.

CONCLUSIONS

The identified patterns contributed to the reduction of drug misidentification and the development of timelier drug labelling and administration.

RELEVANCE TO CLINICAL PRACTICE

The evidence supports the development of standardized labels for the prevention of medication errors.

Usability of smart infusion pumps: A heuristic evaluation

Although smart infusion pumps were built to eliminate medication errors, new types of usability errors have arisen. The purposes of this study were to determine potential risks when using smart pumps during secondary medication administration and to identify opportunities for design improvements. We observed and analyzed nurses when they interacted with smart pumps and heuristically evaluated the smart pump to identify usability problems. Forty-three usability problems were identified with the smart pump. The usability problems have the potential to create high cognitive burden on nurses and to increase the likelihood of mistakes. We discuss design and process improvement recommendations for each major finding from this study.

Analysis of IV Drugs in the Hospital Workflow by Raman Spectroscopy: The Case of Piperacillin and Tazobactam

Medical errors associated with IV preparation and administration procedures in a hospital workflow can even cost human lives due to the direct effect they have on patients. A large number of such incidents, which have been reported in bibliography up to date, indicate the urgent need for their prevention. This study aims at proposing an analytical methodology for identifying and quantifying IV drugs before their administration, which has the potential to be fully harmonized with clinical practices. More specifically, it reports on the analysis of a piperacillin (PIP) and tazobactam (TAZ) IV formulation, using Raman spectroscopy. The simultaneous analysis of the two APIs in the same formulation was performed in three stages: before reconstitution in the form of powder without removing the substance out of the commercial glass bottle (non-invasively), directly after reconstitution in the same way, and just before administration, either the liquid drug is placed in the infusion set (on-line analysis) or a minimal amount of it is transferred from the IV bag to a Raman optic cell (at-line analysis). Except for the successful identification of the APIs in all cases, their quantification was also achieved through calibration curves with correlation coefficients ranging from 0.953 to 0.999 for PIP and from 0.965 to 0.997 for TAZ. In any case, the whole procedure does not need more than 10 min to be completed. The current methodology, based on Raman spectroscopy, outweighs other spectroscopic (UV/Vis, FT-IR/ATR) or chromatographic (HPLC, UHPLC) protocols, already applied, which are invasive, costly, time-consuming, not environmentally friendly, and require specialized staff and more complex sample preparation procedures, thus exposing the staff to hazardous materials, especially in cases of cytotoxic drugs. Such an approach has the potential to bridge the gap between experimental setup and clinical implementation through exploitation of already developed handheld devices, along with the presence of digital spectral libraries.

Do User-Applied Safety Labels on Medication Syringes Reduce the Incidence of Medication Errors During Rapid Medical Response Intervention for Deteriorating Patients in Wards? A Systematic Search and Review

INTRODUCTION

Intravenous medication errors (MEs) occur during medical emergency situations. An initiative, not yet in common practice, that could address these errors is safety labeling. The aim of this review was to identify and appraise research evidence related to the impact of user-applied medication safety labeling on reducing the incidence of MEs during rapid medical response intervention for patient deterioration in the ward setting.

METHODS

A systematic search and review framework was used to conduct the review. A comprehensive database search was conducted of BioMed Central, Clinical Trials, Cumulative Index to Nursing and Allied Health Literature, Expanded Academic ASAP, Joanna Briggs Institute, MEDLINE, OVID, ProQuest Central, PubMed, Wiley Online Library, and World Health Organization Library. The Young and Solomon (2009) critical appraisal tool was used to critically appraise the identified research articles. Each article was then analyzed using a thematic network strategy to identify commonality.

RESULTS

Four primary themes were identified; they were as follows: MEs occur during medical emergency responses (MERs); MEs occur throughout the medication administration process; MERs are stressful and are associated with MEs; and role of medication labeling in reducing MEs during MERs.

DISCUSSION

Greater vigilance is required by health professionals during the medication administration process. The implementation of specific medication safety labeling into the MER could be beneficial in reducing the overall incidence of MEs. Further research is required to validate the merits of a MER medication safety labeling system.

Best Practices to Decrease Infusion-Associated Medication Errors

Infusion-associated medication errors have the potential to cause the greatest patient harm. A 21-year review of errors and near-miss reports from a national medication error-reporting program found that infusion-associated medication errors resulted in the identification of numerous best practices that support patient safety. A content analysis revealed that most errors involved improper dosage, mistaken drug choice, knowledge-based mistakes, skill-based slips, and memory lapses. The multifaceted nature of administering medications via infusions was highlighted. Opportunities for improvements include best practices such as developing learning cultures and reinforcing the independent double-check process on medications. Staff will likely benefit from education on specific medications, prescription details, and smart pump technology.

Strategies to Reduce Patient Harm From Infusion-Associated Medication Errors: A Scoping Review

A scoping review of the literature examined strategies to prevent infusion-associated medication errors. Twenty articles were appraised and revealed studies using different research designs and types of literature reviews. Most were rated low quality. Observations in clinical agencies and laboratory settings were sites of some investigations. The work environment-including staffing, health care providers' education and supervision, standardizing equipment, protocols that supported medication decision-making and administration processes, medication lists, computerized devices, and cognitive aids-were addressed as strategies. The array of studies points to aspects of the complexity of the administration process for infusion-associated medications.
