Incidence of Intravenous Medication Errors in a Chinese Hospital

Evaluation of errors in preparation and administration of intravenous medications in critically ill patients

BACKGROUND

Intravenous medications have greater complexity and require multiple steps in their preparation and administration, which is considered a high risk for patients.

OBJECTIVE

To determine the incidence of intravenous medications preparation and administration errors in critically ill patients.

METHODS

This was an observational, cross-sectional, prospective study design. The study was performed in Wad Medani Emergency Hospital, Sudan .

RESULTS

All nurses working at the study setting were observed over nine days. During the study period, a total number of 236 drugs were observed and evaluated. The total error rate was 940 (33.4%), of which 136 (57.6%) errors with no harm, 93 (39.4%) errors with harm and 7 (3%) of errors associated with mortality. 17 different drug categories were involved, in which antibiotic was the highest error rate 104 (44.1%) and 39 different drugs were involved, in which metronidazole was the most drug involved 34 (14.4%). The total error rate was associated with nurse experience, OR (95% CI); 3.235 (1.834-5.706), and nurse education level, OR (95% CI); 0.125 (0.052-0.299).

CONCLUSION

The study reported high frequency of IV medications preparation and administration errors. Nurse education level, and experiences were influenced the total errors.

Self-reported unsafe medication behaviour among clinical nurses in China: A nationwide survey

AIM

Unsafe medication behaviour was the direct cause of medication error, while the current status of unsafe medication behaviour among Chinese clinical nurses remains uncertain. To investigate unsafe medication behaviour among Chinese nurses and to analyse its associated factors.

DESIGN

A cross-sectional online study was conducted in 31 provinces and municipalities of mainland China.

METHODS

The electronic self-administered questionnaire was used to collect data from July-August 2020, including demographic information (age, gender, initial degree, ultimate education degree, hospital levels, unit nature, professional position, duty, departments, working years and working regions) and an adapted nurse unsafe medication behaviour scale measuring self-reported nurse unsafe medication behaviour (SR-NUMB). A generalized linear mixed model was applied to determine the influencing factors.

RESULTS

A total of 10,153 Chinese nurses responded online, and 7,873 responses that met the time control requirements were included finally. It turned out that 80.49% of Chinese nurses had SR-NUMB. Specifically, 72.81% of them had unsafe medication behaviours in the process of medication administration, followed by medication monitoring (53.09%), medication preservation and dispensing (47.42%), and medical order processing (44.53%). A generalized linear mixed model demonstrated that male nurses and nurses who work in secondary hospitals or general hospitals, those who have higher professional positions or duties, those who have been working for 5-10 years, and those who are working in emergency and intensive critical units may have higher level of SR-NUMB compared to other nurses.

CONCLUSION

Suboptimal SR-NUMB among Chinese nurses was identified in our findings. Associated factors, such as gender, hospital levels, unit nature, professional position, duty, working years and departments, should be targeted in future prevention and intervention efforts for safe medication management among Chinese nurses.

Intravenous Smart Pumps at the Point of Care: A Descriptive, Observational Study

OBJECTIVE

This study was conducted to advance understanding of intravenous (IV) smart pump medication administration practices using the Baxter Spectrum IQ. The primary objective was to observe adherence with manufacturer required IV smart pump system setup at the point of care during actual clinical use.

METHODS

The study was conducted in a 285-bed acute care community hospital near Boston, Massachusetts. The study design was observational and noninterventional, and all data were collected by a single observer. Observations included measurement and documentation of adherence with the Baxter Spectrum IQ system setup requirements.

RESULTS

A total of 200 primary and secondary IV medication administration observations were included: 101 in critical care and 99 in medical-surgical. Overall adherence was found to be: 6.5% with IV smart pump position relative to the patient (aim 1); 6.5% with required position of the primary infusion bag (aim 2); and 69.5% adherence with required position of the secondary medication infusion bag (aim 3). Additional exploratory data were also collected.

CONCLUSIONS

These results add to the emerging body of knowledge, which support that adherence to required system setup for head-height dependent IV smart pumps is low and difficult to achieve during actual clinical use. Consideration of alternative human factors-designed technology to replace the current manual setup requirements is needed to improve the process of acute care IV medication administration in this very important area of patient safety.

A qualitative analysis of intravenous smart pump usability

AIM

To understand the experience of critical care nurses when performing common, yet error-prone, programming tasks on two unfamiliar intravenous smart pumps.

DESIGN

A qualitative descriptive study using data collected during a previous quantitative pilot study.

METHODS

Following completion of common intravenous programming tasks each participant was interviewed using a semi-structured interview guide. All interview data were coded line-by-line and thematic analysis revealed themes across all participants' interviews.

RESULTS

The following four themes were identified: appreciation for attractive design features, the need for efficiency, the importance of intuitive use and concern for patient outcomes. Overall, these themes provide evidence that nurses strongly prefer a more usable intravenous smart pump interface that integrates safeguards to efficiently improve patient outcomes. Findings support the need for intravenous smart pump technology to be developed with an intuitive interface that decreases the level of cognitive demand and will lead to improved patient safety.

Patient Safety Incidents Related to the Use of Parenteral Nutrition in All Patient Groups: A Systematic Scoping Review

INTRODUCTION

There is limited comprehensive literature focussing on the range of patient safety incidents related to parenteral nutrition (PN).

OBJECTIVE

The aim of this review was to examine patient safety incidents related to the use of PN in all patient age groups.

METHODS

Literature published in the English language between January 2000 and April 2020 were searched across the MEDLINE, CINHAL and Embase databases. Articles were included if they contained PN-related patient safety incidents related to an avoidable event. No restrictions were applied to patient populations. The screening process was undertaken independently by two authors.

RESULTS

In total, 108 records were included in the review: 52 case studies, 54 observation studies (e.g. prevalence studies, surveys) and two experimental studies. All age groups were represented, with 62% of studies in paediatrics (of which two-thirds were neonates) and 23% in adults. They included all medication processes: prescribing, dispensing, compounding, administration and monitoring. Incidents were related to microbial contamination, venous access and specific components (e.g. lipid emulsion, amino acids, glucose, micronutrients and electrolytes) or the whole product. Incident outcomes ranging from near miss to death were reported. Intervention studies looked at the impact on patient safety incidents of computerised tools, healthcare processes, e.g. pharmacist screening, and standardisation. One study demonstrated more severe outcomes with paediatric than with adult PN.

CONCLUSIONS

This review demonstrates the vast range of PN-related patient safety incidents in all patient age groups and all medication process stages. The need for a national study looking at patient safety incidents related to PN in England is highlighted.

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.

A Review of Best Practices for Intravenous Push Medication Administration

In 2015, the Institute for Safe Medication Practices (ISMP) released safe practice guidelines for adult intravenous (IV) push medications. ISMP's most recent set of guidelines has added to a growing list of recommendations from professional groups on the safe use of IV medications. These recommendations and guidelines vary with regard to their audience, scope, and terminology. In some ways, these variations may contribute to confusion and delayed adoption of the standards. This report attempts to provide clarity about the rationale and background regarding the need for practice improvement, discussion of various guidelines, and practice mitigation strategies to improve patient safety.

Systematic evidence review of rates and burden of harm of intravenous admixture drug preparation errors in healthcare settings

OBJECTIVE

To examine published evidence on intravenous admixture preparation errors (IAPEs) in healthcare settings.

METHODS

Searches were conducted in three electronic databases (January 2005 to April 2017). Publications reporting rates of IAPEs and error types were reviewed and categorised into the following groups: component errors, dose/calculation errors, aseptic technique errors and composite errors. The methodological rigour of each study was assessed using the Hawker method.

RESULTS

Of the 34 articles that met inclusion criteria, 28 reported the site of IAPEs: central pharmacies (n=8), nursing wards (n=14), both settings (n=4) and other sites (n=3). Using the Hawker criteria, 14% of the articles were of good quality, 74% were of fair quality and 12% were of poor quality. Error types and reported rates varied substantially, including wrong drug (~0% to 4.7%), wrong diluent solution (0% to 49.0%), wrong label (0% to 99.0%), wrong dose (0% to 32.6%), wrong concentration (0.3% to 88.6%), wrong diluent volume (0.06% to 49.0%) and inadequate aseptic technique (0% to 92.7%)%). Four studies directly compared incidence by preparation site and/or method, finding error incidence to be lower for doses prepared within a central pharmacy versus the nursing ward and lower for automated preparation versus manual preparation. Although eight studies (24%) reported ≥1 errors with the potential to cause patient harm, no study directly linked IAPE occurrences to specific adverse patient outcomes.

CONCLUSIONS

The available data suggest a need to continue to optimise the intravenous preparation process, focus on improving preparation workflow, design and implement preventive strategies, train staff on optimal admixture protocols and implement standardisation. Future research should focus on the development of consistent error subtype definitions, standardised reporting methodology and reliable, reproducible methods to track and link risk factors with the burden of harm associated with these errors.

Evaluation of an intravenous preparation information system for improving the reconstitution and dilution process

BACKGROUND

There are very few studies reporting the impact of providing intravenous (IV) preparation information on quality use of antimicrobials, particularly regarding their reconstitution and dilution. Therefore, to improve these processes in IV antimicrobial administration, an IV preparation information system (IPIS) was implemented in a hospital.

OBJECTIVE

We aimed to evaluate the effect of improving reconstitution and dilution by implementing an IPIS in the electronic medical record (EMR) system.

METHODS

Prescriptions and activity records of nurses for injectable antimicrobials that required reconstitution and dilution for IV preparation from January 2008 to December 2013 were retrieved from EMR, and assessed based on packaging label information for reconstituting and diluting solutions. We defined proper reconstitution and dilution as occurring when the reconstitution and dilution solutions prescribed were consistent with the nurses' acting records. The types of intervention in the IPIS were as follows: a pop-up alert for proper reconstitution and passive guidance for proper dilution. We calculated the monthly proper reconstitution rate (PRR) and proper dilution rate (PDR) and evaluated the changes in these rates and trends using interrupted time series analyses.

RESULTS

Prior to the initiation of the reconstitution alert and dilution information, the PRR and PDR were 12.7 and 46.1%, respectively. The reconstitution alert of the IPIS rapidly increased the PRR by 41% (p<0.001), after which the PRR decreased by 0.9% (p=0.013) per month after several months. However, there was no significant change in the rate or trend of the PDR during the study period.

CONCLUSIONS

This study demonstrated that the provision of reconstitution alerts by the IPIS contributed to improving the reconstitution process of IV antimicrobial injection administration. However, providing passive information on dilution solutions was ineffective. Furthermore, solutions to ensure the continuous effectiveness of alert systems are warranted and should be actively sought.
