Background and Significance
Background and Significance
Effective nurse–physician communication is vital to improving patient outcomes,[1]
[2] but communication failures contribute to a majority of sentinel events in hospitals.[3] The Joint Commission has identified improving provider communication and medication
safety as key goals of the Hospital National Patient Safety Goals for 2020.[4] One major tool for provider communication is the electronic health record (EHR),
which is increasingly used in place of verbal communication.[5] EHRs allow communication through structured (e.g., medication orders) and unstructured
pathways (e.g., clinician notes). Structured pathways such as computerized physician
order entry (CPOE) are designed for highly specified and discrete information that
can be checked against information elsewhere in the system. This cross-checking function
enables detecting information mismatch and mitigating medication errors such as incorrect
doses, duplicate medications, and allergic reactions before the error reaches the
patient.[6]
Unstructured pathways in the EHR, such as clinicians' notes, free-text fields in medication
orders, and free-text orders, have very few content restrictions. A free-text order
is a stand-alone order with a text field of limited characters used for asynchronous
communication. Because of the nature of free-text content, the information entered
into these orders is not checked against information in the system. The lack of safety
checks makes free-text orders a potentially risky method of entering medication information
into the EHR. Free-text orders have many different names, including free-text orders,
free-text communication orders, nonmedication orders, and communication orders. The
use of free-text orders for communicating medication information can lead to unintended
consequences if they contain unreliable and inconsistent information.[7] Palchuk et al reviewed 2,914 electronic prescriptions that contained free-text fields
and found discrepancies in 16.1% of the prescriptions.[8] Most (83.8%) of the discrepancies could lead to adverse events, and many (16.8%)
could lead to severe adverse events involving a hospital admission or death.[8] Despite these risks, previous research found that free-text orders are commonly
used to enter medication information. One study found that 9.3% of diabetes medications
were entered via free-text orders.[9] The study showed that analyzing EHR data can uncover the prevalence and severity
of the use of free text to order medications. However, the study analyzed only one
type of medication and the identification of reasons for the use of free- text to
order medication was based on the author's perspectives, not on clinician feedback.
Another two studies found that 42% of free-text orders[10]
[11] contained medication information. Studies on the use of other free-text digital
tools for communication have also found similar rates of medication information.[12] Studies on improving clinician communication have focused on the effectiveness of
specific communication tools or communication strategies. However, they have not studied
improving the effective use of free-text orders in acute settings.[13]
[14]
[15]
[16] There is currently a gap in knowledge between the known prevalence of medication
information in free-text orders and clinicians' rationales for using free-text orders
to communicate medication information. Bridging this knowledge gap is essential for
understanding how to redesign systems to address these issues.
Objectives
In this pilot study, we investigated why clinicians use free-text orders to enter
medication information. We developed clinical case scenarios that varied in clinical
workflow and EHR interaction complexity to investigate: (1) why ordering clinicians
use free-text orders, (2) clinician perceptions of risks associated with using free-text
orders, and (3) potential solutions to improve EHR communication.
Methods
Setting
All participants worked at a Mid-Atlantic teaching hospital. Participants were recruited
through convenience sampling via email to a departmental email distribution list and
compensated for participation. In this study, we use clinicians to refer to health
professionals, including physicians and nurses. Several previous studies focus on
these two groups to understand and improve clinician communication.[17]
[18]
[19]
[20] We included physicians and nurses because they are the primary creators and receivers,
respectively, of free-text orders. Physician and nurse participants from the general
floor and ICUs were recruited to understand common challenges and avoid divergence
from specialty-specific challenges or workflows. The health system uses the Millennium
EHR (Cerner Corporation, Kansas City, Missouri, United States).[21] EHR with hospital-level customizations (e.g., order sets, alerts, etc.). The health
system's institutional review board approved this study.
Clinical Case Scenarios
A human factors expert (S.K. [1]) and a clinical expert (A.Z.H.) conducted a content
analysis of a sample of free-text orders to identify themes driving the use of free-text
orders.[10] These themes were used to construct clinical scenarios for the interview. The scenario
foci and related verbatim text are shown in [Table 1]. The case scenarios helped participants think about various cases and foster discussion
around why free-text orders would be used in such scenarios. While the scenarios were
targeted, we also asked participants to describe example cases where providers would
use free-text orders in addition to the specific scenarios.

Interviews
Clinician interviews are a common approach for understanding the use of technology
in clinician-to-clinician communications. Human factors experts (S.K. [1], D.H., Z.P.,
and S.K. [2]) conducted 16 semi-structured clinician interviews (eight physicians
and eight nurses). The interview guide comprised two broad sections. Section 1 comprised
open-ended questions about medication-related communication preferences in each of
the six scenarios. Physicians were asked to describe how they would communicate medication
information in each scenario. Nurses were asked how they would expect medication information
to be communicated, where they would look for medication information in the EHR, and
how they would communicate the completion of the medication-related task in each scenario.
In section 2, we asked participants about risks and reasons for using free-text orders
(see [Supplementary Material] [available in the online version] for interview guide). A digital survey was administered
after the interview to collect demographic data.
Data Analysis
Interviews were audio-recorded and concurrently captured through live note-taking.
Human factors experts independently analyzed the physician (S.K. [1]) and nurse (Z.P.
and S.O.) interviews using notes and referred to the audio recording if they needed
additional information. Participant's communication preferences in using structured
orders, free-text orders, or verbal communication for each scenario were captured
through frequency counts.
Thematic analyses focused on two questions: (1) when and why are free-text orders
used? and (2) what are the consequences of using free-text orders? Coders independently
read interview notes to identify and extract participants' responses to our focal
research questions. Comments expressing similar concepts across participants were
grouped into themes. After independently coding the physician and nurse interviews,
authors (S.K. [1] and Z.P.) compared themes across the two participant groups. Through
discussion, themes were deconstructed and recombined to improve cohesion and relationship
to the research question. Similar themes were grouped together, disparate themes were
kept separate, and themes were renamed to better describe their contents. The internal
clinician team verified these themes for validity. All analysis was performed by using
Microsoft Excel 2019(Microsoft Corporation, Redmond, Washington, United States).
Results
Eight physicians (one attending physician and seven resident physicians), and eight
nurses working in medical/surgical and ICUs participated in the study. Not all nurses
volunteered demographic data. Participants differed in their level of clinical experience
(attending = 13 years; residents [n = 7] = 3.6 years, standard deviation [SD] = 1.1; nurses [n = 6] = 7.9 years, SD = 3.8). Participants also differed in their level of experience
with the Cerner EHR (attending = 4 years; residents [n = 7] = 1.3 years, SD = 3.2; nurses [n = 6] = 6.2 years, SD = 1.8).
Communication Preferences of Physicians and Nurses
Participants were asked to report communication methods that they would expect to
utilize for each given scenario. Participant's self-reported methods for communicating
medication information are reported in [Fig. 1]. All physicians (n = 8) indicated that they would place medication orders through structured orders
in at least four of the six scenarios. Similarly, at least six nurses expected to
review the medication information either in the medication orders tab or the electronic
Medication Administration Record (eMAR) to retrieve orders in all scenarios. Most
physicians (n = 7) also expected to use verbal communication in five scenarios, but fewer nurses
(n = 5) expected to communicate order completion verbally. Five physicians and seven
nurses expected to use free-text orders in addition to structured orders in at least
one scenario.

in six clinical case scenarios.
Reasons for Using Free-Text Orders
Participants were asked to describe why they believed ordering clinicians used free-text
orders to communicate medication information. Despite risks, both physicians and nurses
mentioned several reasons to use free-text orders. Eight themes emerged from participant
responses on why clinicians use free-text orders including lack of EHR efficiency,
need for redundancy, need for documentation, need for context, lack of EHR functionality,
need for team situation awareness, support for asynchronous workflows, and training
([Table 2]).

Description

Example quote from physicians

Example quote from nurses
|
Lack of EHR efficiency
|
Structured orders can be difficult to complete, difficult to locate, inefficient,
or ineffective. For example, (1) difficulty modifying or updating existing structured
orders; (2) difficulty accessing information from the comments section of structured
orders; (3) confusing visual display of discontinued orders.
|
“Special comments vs. special instructions pop up in different areas for nurses. Not
sure which one they can see.”
|
“Our residents have a lot on their plate, so they are moving fast and may be just
click on the first thing that comes up.”
|
Need for redundancy
|
Communicating medication information through multiple mechanisms is safer because
it increases the likelihood of the order recipient receiving the information.
|
“Just to make sure as a safety net. I did inform the nurse verbally. I also change
the order in the computer but want to make sure.”
|
“It is safer to have (medication information) in more places. If they do not check
this thing, they will check this other thing.”
|
Need for documentation
|
Verbal communication of medications and care plans should be recorded in the EHR for
future reference.
|
“I use (free-text orders) for things that I want to stay on record.”
|
“If it is not spelled out in the order, it would be more prudent to ask the physician
to write it in the communication order because it is easier—the nurse needs it written
to cover their butt.”
|
Need for context
|
Explaining the reason for medication orders gives the order recipient a potentially
useful perspective for patient care.
|
“Can explain why you want to keep it (medication) and rationale for doing it. So they
will be relaxed and you are also relaxed.”
|
“If a physician is trying to be very clear about what they want they would use the
communication section.”
|
Lack of EHR functionality
|
The EHR does not allow all medication tasks to be executed through structured orders.
For example, (1) sequential medications[a]; (2) temporarily holding medications[b]; (3) dynamic medication requirement[c]; and (4) updates on patient status (e.g., “okay to use central lines”).
|
“For most nonmedication orders, we use because there is no specific order in the system.
For okay to travel off monitor, okay to use central line, there is no order. So, I
would use nonmedication order. If order for NPO is already there, there is an order
for discontinue medication in that case I would just follow that order.”
|
NA
|
Need for team situation awareness
|
Appropriate care relies on all team members being informed about the care plan. For
example, (1) ensuring information transmission; (2) allowing nonparticipants of handoffs,
like pharmacists, to be updated; (3) tracking and updating team members about important
changes to the care plan; and (4) reminding them of outstanding tasks.
|
“It (free-text orders) not only helps nurses, but also night-time residents.”
|
NA
|
Support for asynchronous workflows
|
When the order recipient is busy and cannot communicate verbally, the EHR is used
to communicate information.
|
“They want to put that in just to make sure that they have made the nurse aware if
they cannot get in touch with nurse verbally.”
|
NA
|
Training
|
Medication information is communicated through the EHR via workflows learned from
colleagues and mentors.
|
“I have been told to use communication orders; I was told it is for nurses to see.
It is a way for nurse to see orders. Communication between nurse and resident is through
that order.”

a Sequential medications: medications intended to be administered in sequence within
a specific time range.
b Temporarily holding medications: suspending a medication order temporarily without
returning it to pharmacy because the medication may be required a short time after.
c Dynamic medication requirement: intermittent medication schedules such as insulin
drips where nurses must consider dynamic changes in the patients' status and goals
before administering specific medications or deciding the appropriate dose.
Risks with Communication Using Free-Text Orders
Participants were asked to describe any risks that they perceived in the use of free-text
orders. Five risk categories were identified from participant responses. These included
missing orders, increased workload, conflicting information, and lack of safety checks
([Table 3]). All nurses (n = 8) and most physicians (n = 5) mentioned at least one problem with using free-text orders to communicate medication
information.

Missing orders
|
Order recipients may not see free-text orders in the EHR leading to treatment delays.
|
“Several times, these communication orders get lost or the nurse never reviewed them.”
|
“There was a patient with an NG tube placed and an X-ray is supposed to confirm that.
Patient was on a floor and they had the X-ray, but it was never read. There was an
order that said okay to use the line, but no one looked, and the tube feed infused
into the patient's lungs.”
|
Increased workload
|
Additional work due to the use of free-text orders. For examples, (1) relying on other
channels of communication due to a lack of feedback from free-text orders; (2) manually
refreshing the orders tab to receive updates; and (3) manually tracking free-text
order tasks because free-text orders do not populate in the electronic task list.
|
“It is (free-text order) a one-way communication. Even if we put a communication order,
they do whatever they were able to understand from it. It is dangerous, we do not
know what they have done and how much they have understood out of that order. And
what they have done cannot be communicated back to me.”
|
“If you do not check the tab, you will not see the order.”
|
Conflicting information
|
Discrepancies between medication information from outdated free-text orders and between
free-text orders and structured orders. For example, (1) route; (2) dose; (3) timing;
and (4) medication name.
|
“I can use for med orders (in free-text orders), for something like “patient can keep
their nebulizer at bedside” like an ongoing thing. Otherwise if you put communication
order in there, it is there and you do not want it to keep happening and you want
it to happen once; the orders sits there once it's there.”
|
“Patients could ‘have up to a hundred (free-text orders) if they have been in the
hospital for a long time’; “we need to look at date on order or else we will not know
if the order is still relevant.”
|
Lack of safety checks
|
Free-text orders do not undergo pharmacy review, clinical decision support, or bar
code scanning due to unstructured content.

Potential Changes to Improve Communication of Medication Information
Participants were asked to provide recommendations for improving medication information
in the EHR. First, participants wanted new structured orders to be added to their
EHR. They wanted new structured orders to replace common free-text orders (e.g., order
for okay to use central line) and for the handful of paper orders at their hospital
(e.g., continuous drips of heparin and insulin) to be orderable through the EHR. Second,
physicians and nurses wanted free-text medication orders to be more usable. They suggested
features like status tracking (e.g., order reviewed by nurse and order implemented
by nurse), free-text integration with the electronic task list, alerts firing when
new free-text orders appear, making free-text orders easier to see in the EHR, relabeling
free-text orders as medication specific when appropriate, making it easier to discontinue
old free-text orders, and housing all medication orders in the same location in the
EHR. Participants also requested that medication information, whether free-text or
structured, be accessible in the same location. Fourth, participants suggested that
free-text orders facilitate two-way medication-relevant communication between the
ordering and receiving provider. Lastly, participants envisioned building a clinical
decision support tool to check the text of free-text order against relevant medication
safety parameters (e.g., dose, frequency, and route), alternative ordering options
(e.g., standard medication orders), and medications the patient is already on.
Discussion
In this study, we explored clinicians' perceptions of the use of free-text orders
to communicate medication information. The results show that clinicians have varied
perceptions of when and why free-text orders are used, their impact on medication-related
communication and subsequent patient safety risks, and several ideas for improvements
to the design of structured and free-text orders.
In the scenarios, clinicians often reported using structured orders for scenarios
that introduced new medications or dose changes. New medications and dose changes
must be entered through the structured order systems to be evaluated by pharmacists
and accessible through automated medication dispensing cabinets. However, despite
its necessity, the structured ordering system was difficult to use for both the ordering
physician and the nurse. Further, not all medications could be ordered through the
structured order system, especially complex, atypical, or urgent medication information,
resulting in the use of free-text orders as a workaround.
The scenarios also revealed that providers use verbal communication and free-text
orders in addition to structured orders to convey medication information as a workaround
for EHR communication barriers. The clinicians expressed that they required consistent
communication with their team to maintain situation awareness and context, but that
communication also needed to be asynchronous and support the different workflows of
physicians and nurses. However, maintaining consistent communication in the EHR with
structured orders was described as challenging and unreliable (i.e., the nurse not
seeing notes on a structured order, and the structured order not providing sufficient
context for the order), resulting in the use of workarounds. One of these workarounds
is sending redundant medication information in free-text orders to document it in
multiple places in the EHR, where it will hopefully be seen. This finding is supported
by previous research.[22]
[23]
[24]
Physicians mentioned multiple reasons for using free-text orders, while nurses mentioned
fewer reasons for using free-text orders. The difference between physicians and nurses
is likely due to physicians (and advance practice providers) being responsible for
writing orders and documenting clinical reasoning for their team members. As a result,
more physicians were concerned about categories of “lack of EHR functionality,” “need
for team situation awareness,” and “need for documentation.” “Need for redundancy”
was mentioned equally by both nurses and physicians. This similarity between physicians
and nurses is likely because both recognize the need to ensure that information is
not missed. More nurses than physicians mentioned the “need for context” as a reason
to use free-text orders, which possibly reflects the nurse's desire for clarity when
executing orders.
Although clinicians recognize risks associated with using free-text orders, risk perceptions
differ across roles. Unlike structured orders, medication information entered through
free-text orders may not be visible in the standard nursing workflow (e.g., EHR nurse
task list), increasing the risk of missed orders. Canceling free-text orders is not
a part of the clinician's workflow, which leads to outdated free-text orders cluttering
the patient's chart, and more importantly, conflicting information across old and
new orders. These unintended workflow consequences put additional workload burdens
on the order recipient, typically the nurse, to locate, track, and clarify free-text
orders. In alignment with previous studies, while physicians are cognizant of the
challenges with the EHR, they often are unaware of the unintended consequences or
errors associated with using workarounds.[25] The difference in risk perceptions and rationale for using free-text orders points
to a probable lack of understanding of other clinician groups' workflow. An interprofessional
program to observe and learn workflows and challenges of other clinician groups may
enhance effective communication.[26]
Our findings on the risk of free-text orders align with previous research highlighting
how EHR usability issues disrupt clinician work and can contribute to patient harm.[27]
[28]
[29] Free-text orders present technical deficiencies compared with structured orders.
The information entered to free-text orders cannot be checked for accuracy and safety
by the computer (i.e., checking for proper dosing, allergies, medication interactions,
or altering previous orders). The lack of dose and allergy checking could result in
wrong medication or wrong dose errors. Free-text orders present workflow challenges
for nurses because they populate differently from structured orders in the EHR. Nurses'
most common concern in interviews was missing free-text orders, resulting in omission
or delays in care. Consequently, there are many ways that free-text orders can negatively
impact patient safety and result in suboptimal care.
We propose 12 potential solutions to improve structured order reliability and communication
in the EHR to reduce the use of free-text orders and the resulting risks to patient
safety ([Table 4]). Recognizing that many solutions involving EHRs require longer time horizons to
implement, we also provide guidelines on the timeline for implementing the proposed
solutions. Near-term solutions focus on immediate changes that a healthcare system
may have greater control to put in place in less than 4 months. Longer term solutions
are focused on technology changes that may require vendor engagement or policy changes
that often require a longer time horizon beyond 4 months. The proposed solutions seek
to balance implementation time, effectiveness, and sustainability.[30]
[Table 4] also indicates which solutions were suggested by participants during the study and
those strategies identified by the authors.

Prior studies on communication within the EHR have looked at adoption and usage while
only providing superficial recommendations such as improved interface and training,
without concrete design alternatives.[31] The identification of the clinician perceptions on risks and rationale for the use
of free-text orders and potential solutions will add to the literature on enhancing
clinician communication within the EHR. Some of these recommendations, such as the
use of closed-loop feedback for effective communication, are already well known.[13] Other solutions, such as surveillance, are novel and need to be tested before large-scale
implementation.
While the recommendations are targeted to address clinician needs, usability issues,
and risks identified in this study, we need robust methods to design and implement
solutions. Substantial changes require vendors and healthcare systems to allocate
resources to perform usability testing of medication ordering systems before, during,
and after hospital EHR implementation to understand work systems, minimize workarounds
and identify unintended consequences.[32]
[33]
Limitations
One limitation of our study is the use of a single EHR and hospital site and a relatively
small number of participants; consequently, our interviews' results may not be generalizable
to other sites, other EHRs, or larger clinical populations. While interviewing a more
diverse set of participants may glean additional information, our themes have a level
of face validity that suggests these findings are a realistic set of issues to be
remedied. Additionally, the recommendations in [Table 4] could serve as a checklist for health systems using another vendor EHRs. Second,
the physician participants were mostly residents, who typically have more experience
with the EHR than the attendings in an academic setting who sometimes rely on residents
to enter patient orders and may be more familiar with workaround strategies requiring
free-text orders. Third, we asked participants to discuss how they would communicate
medication information, but we did not ask about each specific communication method.
Hence, the data may be biased to participant recollection. Additionally, our analysis
is limited due to the use of notes instead of transcripts, limiting our results by
forgoing speech nuances, as well as the lack of member checking.
The recommendations we pose are based on the reasons and risks of using free-text
orders presented by participants interpreted from a human factors and informatics
lens. The feasibility and unintended consequences of these recommendations have not
been tested. Future studies should investigate the feasibility of these recommendations
as well as the quantity of actual error resulting from the use of free-text order
to communicate medication information.
Conclusion
In this study, we identified several risks associated with the use of free-text order
for communicating medication information. Ordering clinicians use free-text orders
due to various usability and functional deficiencies in current structured medication
order systems. Clinicians noted that the use of free-text orders to communicate medication
information as a workaround could create unintended risks to patient safety. Thoughtful
solutions designed to address why clinicians use free-text orders as a workaround
can improve the medication ordering process and the subsequent medication administration
process.

for using free-text orders to communicate medication information. The study also identified
several risks associated with the use of free-text order for communicating medication
information. Our findings align with previous research highlighting how EHR usability
issues disrupt clinicians' work and can contribute to patient harm. Lack of insight
into reasons and risks associated with the use of free-text orders would prohibit
our efforts to improve communication and reduce medical errors. The proposed solutions
are summarized in [Table 4] and seek to balance implementation time, effectiveness, and sustainability.
Multiple Choice Questions
Multiple Choice Questions
-
Which of the following is intended to be used most frequently for communicating medication
information?
-
Structured CPOE orders
-
Free-text orders
-
Verbal orders
-
Other
Correct Answer: The correct answer is option a. Though verbal orders still exist, EHRs are now ubiquitous
and CPOE ordering is common. Free-text orders are used as workarounds to structured
CPOE orders, with these workarounds largely due to insufficient functionality or usability
of structured CPOE ordering systems. Ideally, well-designed structured CPOE ordering
systems would be used almost universally.
-
Based on the findings of this study, which of the following is not a common reason
for clinicians to use of free-text orders, as opposed to structured CPOE orders, for
communicating medication information in the EHR?
-
The EHR lacks the functionality to order some medications.
-
Clinicians need to document additional information for future reference.
-
Creating free-text orders can be more efficient than creating structured CPOE orders.
-
Clinicians do not know whether some medications are available.
Correct Answer: The correct answer is option d. In this study, clinicians used free-text orders as
a workaround because the EHR currently does not allow all medication tasks (e.g.,
holding medications, sequential administration of medications) to be executed through
structured CPOE orders. Clinicians may also want communication about medications and
care plans to be recorded in the EHR for future reference. Additionally, structured
orders can be time consuming to complete, update, or modify. However, this study did
not show any evidence that free-text orders arise from a lack of knowledge about the
availability of specific medications.
