Multiple Intravenous Infusions Phase 2a: Ontario Survey.

BACKGROUND: Research conducted in earlier phases of this study prospectively identified a number of concerns related to the safe administration of multiple intravenous (IV) infusions in Ontario hospitals. OBJECTIVE: To investigate the potential prevalence of practices or policies that may contribute to the patient safety risks identified in Phase 1b of this study. DATA SOURCES AND REVIEW METHODS: Sixty-four survey responses were analyzed from clinical units where multiple IV infusions may occur (e.g., adult intensive care units). Survey questions were organized according to the topics identified in Phase 1b as potential contributors to patient harm (e.g., labelling practices, patient transfer practices, secondary infusion policies). RESULTS: Survey results indicated suboptimal practices and policies in some clinical units, and variability in a number of infusion practices. Key areas of concern included the following: use of primary IV tubing without back check valves when administering secondary infusions, administration of secondary infusions with/as high-alert continuous IV medications, potential confusion about how IV tubing should be labelled to reflect replacement date and time, interruptions to IV therapy due to IV pump and/or tubing changes when patients are transferred between clinical units, coadministration of continuous or intermittent infusions on central venous pressure monitoring ports, variability in respondents' awareness of the infusion pump's bolus capabilities. LIMITATIONS: Due to the limited sample size, survey responses may not be representative of infusion practices across Ontario. Answers to some questions indicated that the intent of the questions might have been misunderstood. Due to a design error, 1 question about bolus administration methods was not shown to as many respondents as appropriate. CONCLUSIONS: The Ontario survey revealed variability in IV infusion practice across the province and potential opportunities to improve safety.

Intravenous chemotherapy preparation errors: patient safety risks identified in a pan-Canadian exploratory study.

BACKGROUND: This exploratory study was launched following a critical chemotherapy medication incident to thoroughly and proactively examine the current processes for ordering, preparing, labeling, verifying, administering, and documenting ambulatory intravenous chemotherapy in Canada, and to identify factors that may contribute to preventable adverse drug events. METHODS: Field observations in six Canadian cancer centers to identify end-to-end processes in clinic, pharmacy, and treatment areas; analysis of processes to identify risks. RESULTS: Three types of previously locally unrecognized potential chemotherapy preparation errors in Canadian oncology pharmacies were uncovered, all of which are undetectable if they occur. Although the frequency of these errors is unknown, their impact is potentially catastrophic. INTERPRETATION: Dispensing errors in high-risk intravenous preparation have been studied in the past, but it is unlikely that these studies have detected these errors because of the inherent limitations of the detection methods used. Research on preparation errors using more sensitive methods is therefore urgently needed to establish the extent to which pharmacy preparation practices may be error-prone, and to allow reliable evaluation of the impact of mitigation strategies. Widespread practice changes in Canadian oncology pharmacies are necessary, and are currently underway.

Optimizing the design of preprinted orders for ambulatory chemotherapy: combining oncology, human factors, and graphic design.

PURPOSE: To establish a set of guidelines for developing ambulatory chemotherapy preprinted orders. METHODS: Multiple methods were used to develop the preprinted order guidelines. These included (A) a comprehensive literature review and an environmental scan; (B) analyses of field study observations and incident reports; (C) critical review of evidence from the literature and the field study observation analyses; (D) review of the draft guidelines by a clinical advisory group; and (E) collaboration with graphic designers to develop sample preprinted orders, refine the design guidelines, and format the resulting content. RESULTS: The Guidelines for Developing Ambulatory Chemotherapy Preprinted Orders, which consist of guidance on the design process, content, and graphic design elements of ambulatory chemotherapy preprinted orders, have been established. CONCLUSION: Health care is a safety critical, dynamic, and complex sociotechnical system. Identifying safety risks in such a system and effectively addressing them often require the expertise of multiple disciplines. This study illustrates how human factors professionals, clinicians, and designers can leverage each other's expertise to uncover commonly overlooked patient safety hazards and to provide health care professionals with innovative, practical, and user-centered tools to minimize those hazards.

Human factors perspectives on a systemic approach to ensuring a safer medication delivery process.

The current, prevailing approach to addressing medication delivery safety issues has been to apply solutions at the point of failure with direct, local remediation. These include computerized physician order entry to address transcription and prescribing problems, tall man lettering for label clarity and smart pump systems to address programming use errors. We discuss the lack of a systemic, holistic approach to addressing medication delivery issues that has led to fragmented solutions that do not address the problem as intended and introduce new, unintended patient safety issues. We use recent case studies in addition to our own experimental data from human factors investigations to show how a comprehensive human factors approach can be applied to address systemic error in medication delivery. Only by identifying how (1) subsystems interconnect, (2) information flows, (3) care providers communicate and (4) users are impacted will healthcare organizations and system vendors be able to fully address error in medication delivery. Much of what is required from organizations is to transcend the organizational boundaries of medicine, pharmacy and nursing to produce a delivery system that ensures an integrated approach that addresses all stakeholders' needs.
