Clinician Perceptions on the Use of Free-Text Communication Orders

Pseudorandomized Testing of a Discharge Medication Alert to Reduce Free-Text Prescribing

BACKGROUND

Pseudorandomized testing can be applied to perform rigorous yet practical evaluations of clinical decision support tools. We apply this methodology to an interruptive alert aimed at reducing free-text prescriptions. Using free-text instead of structured computerized provider order entry elements can cause medication errors and inequity in care by bypassing medication-based clinical decision support tools and hindering automated translation of prescription instructions.

OBJECTIVE

The objective of this study is to evaluate the effectiveness of an interruptive alert at reducing free-text prescriptions via pseudorandomized testing using native electronic health records (EHR) functionality.

METHODS

Two versions of an EHR alert triggered when a provider attempted to sign a discharge free-text prescription. The visible version displayed an interruptive alert to the user, and a silent version triggered in the background, serving as a control. Providers were assigned to the visible and silent arms based on even/odd EHR provider IDs. The proportion of encounters with a free-text prescription was calculated across the groups. Alert trigger rates were compared in process control charts. Free-text prescriptions were analyzed to identify prescribing patterns.

RESULTS

Over the 28-week study period, 143 providers triggered 695 alerts (345 visible and 350 silent). The proportions of encounters with free-text prescriptions were 83% (266/320) and 90% (273/303) in the intervention and control groups, respectively (p = 0.01). For the active alert, median time to action was 31 seconds. Alert trigger rates between groups were similar over time. Ibuprofen, oxycodone, steroid tapers, and oncology-related prescriptions accounted for most free-text prescriptions. A majority of these prescriptions originated from user preference lists.

CONCLUSION

An interruptive alert was associated with a modest reduction in free-text prescriptions. Furthermore, the majority of these prescriptions could have been reproduced using structured order entry fields. Targeting user preference lists shows promise for future intervention.

Free-Text Computerized Provider Order Entry Orders Used as Workaround for Communicating Medication Information

OBJECTIVES

Medication information is frequently communicated via free-text computerized provider order entry (CPOE) orders in electronic health records. When such information is transmitted separately from a structured CPOE medication order, there is a significant risk of medication error. Although prior studies have described the frequency of using free-text CPOE orders for communicating medication information, there is a gap in understanding the nature of the medication information contained in the free-text CPOE orders. The aims of this study are to (1) identify the most common medication names communicated in free-text CPOE orders and their risk levels and (2) identify what actions physicians expect that nurses will complete when they place free-text CPOE orders, and (3) describe differences in these patterns across hospitals.

METHODS

This study was a retrospective analysis of a sample of 26,524 free-text CPOE orders from 6 hospitals in the mid-Atlantic U.S. region.

RESULTS

Free-text CPOE orders contained in the sample mentioned 193 medication names. Free-text CPOE orders were used frequently to communicate information about naloxone, heparin, flumazenil, and dextrose. Twenty-two percent of the free-text CPOE orders related to discontinuing medication(s), whereas 7% of the free-text CPOE orders relate to giving medication(s). There was high variation across hospitals both in the percentage of free-text CPOE orders mentioning medication information and in the proportion of those that referred to high-risk medications.

CONCLUSIONS

The prevalence of medication information in free-text CPOE orders may suggest specific communication challenges in respect to urgency, uncertainty, planning, and other aspects of communication and clinical needs. Understanding and addressing communication challenges around commonly mentioned medication names and actions, especially those that are high risk, can help reduce the risk of medication errors.

Information handoffs in critical care and their implications for information quality: A socio-technical network approach

OBJECTIVE

The design of health ICTs, as well as human factors, have been shown to influence patient information quality. The aim of this study was to understand how patterns of interaction between these factors influence information quality aspects in a critical care environment.

METHOD

We conducted an ethnographic study of socio-technical information handoffs in a critical care unit. Data collection methods included non-participant observations and semi-structured interviews. Methodological principles from network analysis (SNA, VNA) were used to develop visual network diagrams, as well as to analyze the composition of the information network and its influence on patient information quality.

RESULTS

The network patterns that emerged uncover that human actors have many information processing and dissemination roles at the critical care unit. However, ICTs play key network roles, acting as information intermediaries and gatekeepers. We further identify three types of information handoffs in the critical care environment - human-human, human-ICT and ICT-human. On the one hand, we find that human-human and ICT-human handoffs influence contextual and intrinsic aspects of patient information, such as information completeness and accuracy. On the other hand, human-ICT handoffs influence information accessibility and representational quality, such as consistency and interpretability.

DISCUSSION

The results suggest that standardizing change of shift handoff communication may not be sufficient to prevent information decay in complex care trajectories. In particular, we argue that ensuring information consistency and interpretability across disciplines and professions is as important as ensuring information completeness and accuracy during change of shift handoffs. ICT and workflow design opportunities are discussed as means to address overlapping or conflicting information needs across disciplines and professions, increase information consistency, and reduce information redundancy across the network.
