Predisposing Factors to Medication Errors by Nurses and Prevention Strategies: A Scoping Review of Recent Literature

Medication errors have serious consequences and high costs for the patient and the system. The treatment process and the care required for critically ill patients are complex, and these patients are more vulnerable to errors and potential consequences. A scoping review using the JBI methodology was conducted across PubMed, CINAHL, and MEDLINE databases and reported by the PRISMA-ScR guidelines to explore strategies that can mitigate medication errors by nurses. The search strategy focused on references published between January 2012 and April 2023. Sixteen studies were included, and the results were organized into thematic areas. Medication errors by nurses are in the areas of preparation, administration, and documentation; organizational, system-related, procedural, personal, and knowledge and training factors are predisposing factors for errors; educational intervention, verification and safety methods, organizational changes, and error reporting are the strategic areas to mitigate medication error. The organization of the data could be different, as it depends on the reviewers' experience. Knowledge of the factors that cause medication errors and interventions to mitigate them make it possible to outline strategies to minimize their occurrence and achieve health gains. The protocol preceding this review has been registered in the Open Science Framework and published.

Investigation of interventions to reduce nurses' medication errors in adult intensive care units: A systematic review

BACKGROUND

Medication errors in adult intensive care units (ICUs) are both frequent and harmful. For nurses, these errors may be multifactorial and multidisciplinary, extending from prescription stage to monitoring of patient response to medication. Therefore, diverse interventions have been developed to optimise the medication process to prevent such errors.

OBJECTIVES

The objective of this systematic review was to identify research investigating interventions that may be effective in reducing the rate of nurses' medication errors in adult ICUs.

METHODS

A systematic search was undertaken of three databases: Cumulative Index of Nursing and Allied Health Literature, Medical Literature Analysis and Retrieval System Online, and EMCARE using a combination of key terms related to "medication errors", "nurses", "interventions", and "intensive care units". The search was limited to studies published in English between 2009 and 2019. Independent screening, quality appraisal, and data extraction were undertaken by two reviewers.

RESULTS

A total of 464 records were identified from database searches. Eleven studies met inclusion criteria: ten were quasi-experimental designs and one was a randomised controlled trial. Studies examined six types of interventions: prefilled syringes, barcode-assisted medication administration, an automated dispensing system, nursing education programs, a protocolised program logic form, and a preventive interventions program with protocols and pharmacist-supported supervision and monitoring. Findings revealed that a prefilled syringe, nurses' education programs, and the protocolised program logic form were most effective in reducing medication errors. For the barcode-assisted medication administration, automated dispensing systems, and a preventive interventions program with protocols and pharmacist-supported supervision and monitoring, results showed wide variability in effectiveness.

CONCLUSION

This review found that the evidence for effective interventions to reduce nurses' medication errors in adult ICUs is limited, due largely to inconsistencies in research design and methods. Therefore, further studies such as randomised controlled trials focusing on a single intervention are required to provide robust evidence of the effectiveness of interventions.

Nurse management of vasoactive medications in intensive care: A systematic review

AIM AND OBJECTIVE

To investigate how intensive care nurses prepare, initiate, administer, titrate, and wean vasoactive medications.

BACKGROUND

The management of vasoactive medications is core business for intensive care nurses, but little is known on how nurses manage these ubiquitous and potentially harmful medications.

DESIGN

A systematic review of the literature with narrative synthesis of data.

METHODS

The databases CINAHL Complete, Medline Complete and EMBASE were searched from 1965 to January 2019 with keywords under five concept headings and in a variety of configurations. This systematic review was conducted according to the PRISMA guidelines. Studies were assessed for quality and bias, and a modified narrative synthesis was used to analyse data, investigate findings and explore relationships within and between studies.

RESULTS

The review identified 13 studies: two observational studies, two pre and post intervention studies, four survey studies, two quasi-experimental studies, one longitudinal time series, one prospective controlled trial, and one interview incorporating content analysis. Four studies on preparing and initiating vasoactive medications described a lack of standardisation in infusion preparation and inconsistencies in dosing units and patient weights. Five of six studies on vasoactive medication administration examined nurses' use of syringe changeovers to reduce patient haemodynamic compromise and there were three studies on titration and weaning.

CONCLUSION

Further research on nurse management of vasoactive medications is needed to develop an evidence base for specialist education and standardised practices aimed at reducing risk for patient harm.

RELEVANCE TO CLINICAL PRACTICE

Nurses working in intensive care units in many parts of the world are responsible for the management of vasoactive medications. There is great variation in practices that include preparation, initiation, administration, titration and weaning of vasoactive medications, which increases the risk for medication errors and adverse events in a vulnerable population of critically ill patients.

A robotic system to prepare IV solutions

Drugs need to be used regularly and correctly in order to be effective. When medicines are used correctly, negativities that threaten human health and life can be avoided, but they can cause unwanted situations that can occur until the end of life when they are used incorrectly. The most common drug administration errors in hospitals are: The wrong dosage of the drug given to the patient, the timing and / or the method of administration, the wrong drug given to the patient, the drug given to the wrong patient, or even not given. Furthermore, the information about the drug that is administered to the patient may not be registered at all. In this research, a robotic drug preparation system and a communication server accepting prescription orders have been developed. Component engineering methodology is further utilized in the design of the Drug Preparation System to maximize reuse, increase product reliability, reduce design, code and test efforts. The IV Robotic Drug Preparation Robot is composed of a robotic work station and a Cartesian carrier to carry the work station to the desired location. The robotic work station has several grippers to handle syringes, to pull the piston of the syringe and to lock the closed system connector to the vial. The IV Robotic Drug Preparation System and communication server are developed and being used in the hospitals. Due to this system, medicines left unused in vials can be used and a great amount of savings is obtained from the drug purchases.
