Nursing Strategies to Increase Medication Safety in Inpatient Settings

Original Research: Exploring Medication Safety Practices from the Nurse's Perspective

BACKGROUND

Medication preparation and administration are complex tasks that nurses must perform daily within today's complicated health care environment. Despite more than two decades of efforts to reduce medication errors, it's well known that such errors remain prevalent. Obtaining insight from direct care nurses may clarify where opportunities for improvement exist and guide future efforts to do so.

PURPOSE

The study purpose was to explore direct care nurses' perspectives on and experiences with medication safety practices and errors.

METHODS

A qualitative descriptive study was conducted among direct care nurses employed across a large health care system. Data were collected using semistructured interview questions with participants in focus groups and one-on-one meetings and were analyzed using qualitative direct content analysis.

RESULTS

A total of 21 direct care nurses participated. Four major themes emerged that impact the medication safety practices of and errors by nurses: the care environment, nurse competency, system influences, and the error paradigm. These themes were often interrelated. Most participants depicted chaotic environments, heavy nursing workloads, and distractions and interruptions as increasing the risk of medication errors. Many seemed unsure about what an error was or could be.

CONCLUSIONS

The complexity of medication safety practices makes it difficult to implement improvement strategies. Understanding the perspectives and experiences of direct care nurses is imperative to implementing such strategies effectively. Based on the study findings, potential solutions should include actively addressing environmental barriers to safe medication practices, ensuring more robust medication management education and training (including guidance regarding the definition of medication errors and the importance of reporting), and revising policies and procedures with input from direct care nurses.

Compatibility of Omadacycline With Select Parenteral Products in Simulated Y-site Administration

PURPOSE

Omadacycline is a broad-spectrum intravenous and oral tetracycline antibiotic approved for the treatment of community-acquired bacterial pneumonia and acute bacterial skin and skin structure infections. Available information on the compatibility of intravenous omadacycline is limited to sterile water, 0.9% sodium chloride, and 5% dextrose via a dedicated line. The objective of this work was to determine the intravenous compatibility of omadacycline with commonly used intravenous fluids and medications using simulated Y-site administration.

METHODS

Omadacycline was prepared at concentrations consistent with a maintenance dose (1 mg/mL) and a loading dose (2 mg/mL) with 0.9% sodium chloride according to the prescribing information. Compatibility via simulated Y-site administration was assessed with selected crystalloids (lactated Ringer's solution, magnesium sulfate, and normal saline with potassium chloride) and intravenous medications (bumetanide, furosemide, heparin, and insulin). Y-site administration was simulated by mixing 5 mL of omadacycline with 5 mL of each parenteral product prepared at standard concentrations for infusion. Compatibility was assessed by using visual, Tyndall beam, microscopy, and spectrophotometry methods at 0, 30, and 60 minutes.

FINDINGS

Omadacycline appeared physically compatible with lactated Ringer's solution, magnesium sulfate, normal saline with potassium chloride, bumetanide, heparin, and insulin at standard infusion concentrations. However, although the lower concentrations of omadacycline 1 mg/mL and furosemide 2 mg/mL showed compatibility, higher concentrations of either agent in combination resulted in incompatibility.

IMPLICATIONS

Omadacycline appeared physically compatible with all products tested and incompatible with furosemide. Simultaneous administration of omadacycline with tested intravenous medications, except furosemide, is suggested to be safe.

An urban medical system's exploratory study of medication errors

AIMS

This study sought to identify patterns of medication errors with respect to shifts, day of week, unit involved, severity, medication class and cause of errors and to propose possible solutions.

DESIGN

This was a retrospective explorative study using a database containing 605 medication events from two medical centres. Variables assessed include medication type, the error severity, and time the medication was ordered, the unit that the error occurred on and the day of the week of the errors.

METHODS

Simple percentages were used to report the results, and point-biserial correlation was employed to test for significant differences between the day and night shifts.

RESULTS

There were no statistically significant findings when comparing event severity against the a.m. or p.m. shifts. The medication classes with the most errors were antibiotics, and the most common reason cited for errors was dose omission. The most commonly reported severity level was a 2 which requires increased patient monitoring.

Interruptions during intravenous medication administration: A multicentre observational study

AIMS

The aim of this study was to determine the frequency and cause of interruptions during intravenous medication administration, which factors are associated with interruptions and to what extent interruptions influence protocol compliance.

BACKGROUND

Hospital nurses are frequently interrupted during medication administration, which contributes to the occurrence of administration errors. Errors with intravenous medication are especially worrisome, given their immediate therapeutic effects. However, knowledge about the extent and type of interruptions during intravenous medication administration is limited.

DESIGN

Multicentre observational study.

METHODS

Data were collected during two national evaluation studies (2011 - 2012 & 2015 - 2016). Nurses were directly observed during intravenous medication administration. An interruption was defined as a situation where a break during the administration was needed or where a nurse was distracted but could process without a break. Interruptions were categorized according to source and cause. Multilevel logistic regression analyses were conducted to assess the associations between explanatory variables and interruptions or complete protocol compliance.

RESULTS

In total, 2,526 intravenous medication administration processes were observed. During 291 (12%) observations, nurses were interrupted 321 times. Most interruptions were externally initiated by other nurses (19%) or patients (19%). Less interruptions occurred during the evening (odds ratio: 0.23 [95% confidence interval: 0.08-0.62]). Do-not-disturb vests were worn by 61 (2%) nurses. No significant association was found between being interrupted and complete protocol compliance.

CONCLUSION

An interruption occurred in every eight observed intravenous medication administration, mainly caused by other nurses or patients. One needs to consider critically which strategies effectively improve safety during the high-risk nursing-task of intravenous medication administration.

Impact of Interruptions, Distractions, and Cognitive Load on Procedure Failures and Medication Administration Errors

Medication administration errors are difficult to intercept since they occur at the end of the process. The study describes interruptions, distractions, and cognitive load experienced by registered nurses during medication administration and explores their impact on procedure failures and medication administration errors. The focus of this study was unique as it investigated how known individual and environmental factors interacted and culminated in errors.
