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.

Assessment of technology-assisted technician verification of compounded intravenous sterile preparations versus pharmacist verification

PURPOSE

This study is an evaluation of technology-assisted technician verification (TATV) of the compounded sterile product (CSP) preparation process as an alternative to final verification by a pharmacist.

METHODS

A 2-phase, single-center noninferiority study was conducted to assess the accuracy and CSP processing time with TATV versus pharmacist verification. Phase I of the study was a validation of the internal pharmacist accuracy rate in which 2 pharmacists checked each CSP. In phase II, prepared CSPs were first checked by a technician and then checked by a pharmacist. Technicians were required to complete baseline credentialing and training requirements to participate in the study. The primary outcome was the error rate for the pharmacist check in phase I and the error rate of the technician check in phase II. Secondary outcomes included total verification time and total dose processing time in each phase. The Farrington-Manning test was used for noninferiority assessment of accuracy, and the Wilcoxon rank sum test was used to detect a difference between the processing times.

RESULTS

A total of 4,000 doses were checked in each phase. Pharmacist accuracy was 99.600% in phase I, compared to TATV accuracy of 99.575% in phase II. TATV of CSPs was noninferior to pharmacist verification (absolute difference in accuracy, 0.025%; 95% CI, -0.26% to 0.31%; P = 0.0016). Total verification time and total dose processing times were significantly lower in Phase II.

CONCLUSION

This study showed that TATV of CSPs is noninferior to pharmacist final verification and does not negatively impact the time to check CSPs or total CSP processing time.

Telepharmacy in oncology care: A scoping review

INTRODUCTION

Telepharmacy has the potential to enhance pharmacy services in oncology care, especially in remote areas. This scoping review explored the range, critical benefits and barriers of using telepharmacy services in oncology care.

METHODS

The scoping review followed the Arksey and O'Malley's five-stage framework to identify available evidence. PubMed, CINAHL, Embase, PsycINFO, Ovid MEDLINE and Scopus databases were searched for original research published between 2010 and 2020. The five dimensions of the Alberta Quality Matrix for Health were used to analyse reported outcomes.

RESULTS

Eligible articles (n = 21) were analysed. Telepharmacy in oncology care was used for follow-up, monitoring and counselling, intravenous chemotherapy and sterile compounding, expanding availability of pharmacy services, and remote education. Telepharmacy obtained high acceptability among cancer patients (n = 5) and healthcare professionals (n = 5), and increased accessibility of pharmaceutical services to underserved cancer populations (n = 2). Commonly cited effectiveness and safety outcomes were improved patient adherence (n = 5), increased pharmacy services (n = 3) and early identification of medication-related problems (n = 5). Telepharmacy improved efficiency in staffing and workload (n = 3), and increased cost savings (n = 3). A shortage of resources (n = 5), technical problems (n = 4) and prolonged turnaround time (n = 4), safety concerns (n = 2) and patient willingness to pay (n = 1) were identified barriers to implementing telepharmacy in oncology care.

DISCUSSION

Despite evidence pointing to the advantages and opportunities for expanding oncology pharmacy services through telepharmacy, certain challenges remain. Further research is needed to investigate safety concerns and patient willingness to pay for telepharmacy services.

Impact of technology-assisted versus manual sterile compounding on safety and efficiency in a Canadian community hospital

Purpose

Interventions to improve the safety and efficiency of manual sterile compounding are needed. This study evaluated the impact of a technology-assisted workflow system (TAWS) on sterile compounding safety (checks, traceability, and error detection), and efficiency (task time).

Methods

Observations were conducted in an oncology pharmacy transitioning from a manual to a TAWS process for sterile compounding. Process maps were generated to compare manual and TAWS checks and traceability. The numbers and types of errors detected were collected, and task times were observed directly or via TAWS data logs.

Results

Analysis of safety outcomes showed that, depending on preparation type, 3 to 4 product checks occurred in the manual process, compared to 6 to 10 checks with TAWS use. TAWS checks (barcoding and gravimetric verification) produced better traceability (documentation). The rate of incorrect-drug errors decreased with technology-assisted compounding (from 0.4% [5 of 1,350 preparations] with the manual process to 0% [0 of 1,565 preparations] with TAWS use; P < 0.02). The TAWS increased detection of (1) errors in the amount of drug withdrawn from vials (manual vs TAWS, 0.4% [5/1,350] vs 1.2% [18/1565]; P < 0.02), and (2) errors in the amount of drug injected into the final container (manual vs TAWS, 0% [0/1,236] vs 0.9% [11/1,272]; P < 0.002). With regard to efficiency outcomes, TAWS use increased the mean mixing time (manual vs TAWS, 275 seconds vs 355 seconds; P < 0.001), had no significant impact on average visual checking time (manual vs TAWS, 21.4 seconds vs 21.6 seconds), and decreased average physical checking time (manual vs TAWS, 58.6 seconds vs 50.9 seconds; P < 0.001).

Conclusion

In comparison to manual sterile compounding, use of the TAWS improved safety through more frequent and rigorous checks, improved traceability (via superior documentation), and enhanced error detection. Results related to efficiency were mixed.

Practice-enhancing publications about the medication-use process in 2020

DISCLAIMER

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

PURPOSE

This article identifies, prioritizes, and summarizes published literature on the medication-use process (MUP) from calendar year 2020 that can impact health-system pharmacy daily practice.

SUMMARY

The MUP is the foundational system that provides the framework for safe medication utilization within the healthcare environment. The MUP is defined in this article as having the following components: prescribing/transcribing, dispensing, administration, and monitoring. Articles evaluating at least one step of the MUP were assessed for their usefulness in practice improvement. A PubMed search for articles published in calendar year 2020 was conducted in January 2021 using targeted Medical Subject Headings (MeSH) keywords, and the table of contents of selected pharmacy journals was searched, providing a total of 9,433 articles. A thorough review identified 49 potentially practice-enhancing articles: 15 for prescribing/transcribing, 10 for dispensing, 6 for administration, and 18 for monitoring. Ranking of the articles for importance by peers led to the selection of key articles from each category. The highest-ranked articles are briefly summarized, with a mention of why they are important within health-system pharmacy. The other articles are listed for further review and evaluation.

CONCLUSION

It is important to routinely review the published literature and to incorporate significant findings into daily practice. This article assists in identifying and summarizing the most impactful recently published literature. Health-system pharmacists have an active role in improving the MUP in their institution, and awareness of the moist significant published studies can assist in changing practice at the institutional level.

Use and impact of technology-assisted workflow (TAWF) systems for drug compounding in pharmacy practice: a scoping literature review

Objectives

The aim of this study was to review studies describing the use and the impact of technology-assisted workflow (TAWF) systems for drug compounding in hospital pharmacy.

Content

This is a scoping literature review. A search was conducted on studies describing or evaluating the use of TAWF published from January 1st, 2015 to July 31st, 2021. Two databases were searched (PubMed and Embase), followed by a search on Google Scholar.

Summary

218 articles were screened and 17 were identified as meeting the inclusion criteria. TAWFs all included preparation assistance software (17/17), barcode reader (17/17), photo or video taking (17/17), and some included gravimetric systems (8/17), and the use of robots (2/17). A majority of the studies included used technology for parenteral preparations (15/17, one for oral preparations only (1/17), and one used technology for both types of preparations (1/17). Most of the articles selected presented drugs prepared for adults (10/17), the others presented drugs intended for children (4/17) or for a mix of adults and children (3/17). Four parameters were evaluated: error detection rate (n=15), preparation and validation time (n=7), and costs generated or saved (n=7). Ten studies evaluated the pre-post impact of implantation of a TAWF (10/17).

Outlook

Given the heterogeneity of the data available, the use of TAWF was associated with an increased ability to detect preparation errors, a reduction in preparation time and costs, and increased satisfaction of pharmacy technicians and pharmacists. However, better quality studies are needed to confirm the positive impacts studied.
