Interhospital patient transfers must be standardized
Imagine the following scenario: a hospitalist on the previous shift accepted a patient from another hospital and received a verbal sign-out at the time of acceptance. Now, 14 hours later, a bed at your hospital is finally available. You were advised that the patient was hemodynamically stable, but that was 8 hours ago. The patient arrives in respiratory distress with a blood pressure of 75/40, and phenylephrine running through a 20g IV in the forearm.
A 400-page printout of the patient’s electronic chart arrives – but no discharge summary is found. You are now responsible for stabilizing the patient and getting to the bottom of why your patient decompensated.
The above vignette is the “worst-case” scenario, yet it highlights how treacherous interhospital transfer can be. A recent study, published in the Journal of Hospital Medicine (doi: 10.1002/jhm.2515), found increased in-hospital mortality (adjusted odds ratio 1.36 [1.29-1.43]) for medical interhospital transfer patients as compared with those admitted from the ED. When care is transferred between hospitals, additional hurdles such as lack of face-to-face sign-out, delays in transport and bed availability, and lack of electronic medical record (EMR) interoperability all contribute to miscommunication and may lead to errors in diagnosis and delay of definitive care.
Diametrically opposed to our many victories in providing technologically advanced medical care, our inability to coordinate even the most basic care across hospitals is an unfortunate reality of our fragmented health care system, and must be promptly addressed.
There currently exists no widely accepted standard of care for communication between hospitals regarding transferred patients. Commonalities include a mandatory three-way recorded physician verbal handoff and a transmission of an insurance face sheet. However, real-time concurrent EMR connectivity and clinical status updates as frequently as every 2 hours in critically ill patients are uncommon, as our own study found (doi: 10.1002/jhm.2577).
The lack of a standard of care for interhospital handoffs is, in part, why every transfer is potentially problematic. Many tertiary referral centers receive patients from more than 100 different hospitals and networks, amplifying the need for universal expectations. With differences in expectations among sending and receiving hospitals, there is ample room for variable outcomes, ranging from smooth transfers to the worst-case scenario described above. Enhanced shared decision making between providers at both hospitals, facilitated via communication tools and transfer centers, could lead to more fluid care of the transferred patient.
In order to establish standardized interhospital handoffs, a multicenter study is needed to examine outcomes of various transfer practices. A standard of communication and transfer handoff practices, based on those that lead to better outcomes, could potentially be established. Until this is studied, it is imperative that hospital systems and the government work to adopt broader EMR interoperability and radiology networks; comprehensive health information exchanges can minimize redundancy and provide real-time clinical data to make transfers safer.
Ideally, interhospital transfer should provide no more risk to a patient than a routine shift change of care providers.

Interhospital Transfer Handoff Practices
Transitions of care are major sources of preventable medical errors. Incomplete or inaccurate communication during handoffs is the root cause of many adverse events.[1] In a prospective study, adverse events were found to occur during interhospital transfer up to 30% of the time.[2] Furthermore, patients subject to interhospital transfer have longer length of stay and higher inpatient mortality, even after adjusting for mortality risk predictors.[3] Standardizing intrahospital handoff structures and communication practices has been shown to reduce medical errors.[4, 5, 6] Interhospital transfer is an understudied area among the transitions of care literature. Little is known about institutional variations in the process of information transfer and its association with patient outcomes. Although it is challenging to ascertain the total burden of transferred patients, it has been estimated that 1.6 million inpatients originated at another facility.[7] Additionally, approximately 5.9% of admissions to a representative sample of US intensive care units (ICU) originated from other hospitals.[8] Patients are transferred between hospitals for multiple reasons beyond medical necessity, for example, to adjust for patient preferences, bed availability, and hospital staffing patterns. This creates a setting in which complex and often critically ill patients are subject to variable and sometimes ambiguous handoff processes.[9]
This survey of 32 tertiary care centers in the United States was undertaken to identify common practices in communication and documentation during interhospital patient transfers. Additional goals were to understand the structure of the handoff process, the role of the transfer center, and how electronic medical records (EMR) and interhospital communication play a role in this care transition. Subsequently, common challenges in coordinating interhospital transfers were identified to provide a conceptual framework for process improvement.
METHODS
Survey Process
The survey was initiated in September 2013 and concluded in September 2015, and was designed to quantify patient volume and identify common as well as unique practices to improve communication across the transfer process. The respondents were transfer center directors or managers, typically with a nursing background. Mass e‐mail generated a very poor response rate and did not allow for discussion and clarification of responses. The strategy was then modified to contact individual institutions directly. The survey was performed via phone whenever possible. Figure 1 represents purposeful sampling conducted on 2 different groups of hospitals. These hospitals represent a convenience sample of institutions from a nationally ranked list of hospitals as well as others comparable to our own institutions. Hospitals were selected based on status as academic tertiary care centers with roughly similar bed sizes (600). Several were selected based on similar EMR capabilities. Geographic diversity was also taken into account. Thirty‐two academic tertiary care centers were ultimately included in the survey. Data were entered into a survey form and deidentified. The RutgersRobert Wood Johnson Medical School Institutional Review Board approved this study.
Survey Content
Qualitative and quantitative data were collected by the study team. Data included number and origin of transfers (including those from inpatient facilities and emergency departments), staff characteristics, transfer process, documentation received prior to transfer, EMR access and type, outcomes, and clinical status tracking (see Supporting Figure 1 in the online version of this article for the complete survey tool).
Measurement and Data Analysis
Descriptive statistics are presented in unweighted fashion as a number and percentage for dichotomous variables, or a numeric range for ordinal variables. When a range was given by survey participants, the lower end of the range was used to calculate the population median. Several institutions surveyed were unable to provide specific numeric values, but instead cited how many requests for transfer they received either daily or monthly; these were omitted from the demographics analysis.
Respondents also provided a description of their overall triage and acceptance process for qualitative analysis. Unique strategies were identified by the study personnel at the time of each interview and amassed at the end of the interview period. These strategies were then discussed by the study team, and separated into categories that addressed the main challenges associated with interhospital transfers. Five general tenants of the transfer process were identified: acceptance and transport, need for clinical updates, provider handoffs and coordination of care, information availability, and feedback.
RESULTS
Based on a survey question asking respondents to estimate the total number of interhospital transfers received per month, the annual burden of patients transferred into these 32 hospitals represented approximately 247,000 patients yearly. The median number of patients transferred per month, based on a point estimate if given or the lower end of the range if a range was provided, was 700 (range, 2502500). On average, 28% (range, 10%50%) were transferred directly to an ICU, representing approximately 69,000 critically ill patients. A majority of hospitals polled (65%) received patients from more than 100 referring institutions, and a minority (23%) identified EMR interoperability for more than a quarter of the sending facilities. The overall acceptance rate ranged from 50% to 95%.
Table 1 represents common transition elements of participating institutions. Thirty‐eight percent of hospitals utilize a critical caretrained registered nurse as the initial triage point of contact. The process and quality controls for coordinating transfers from outside hospitals were highly variable. Although clinical updates from acceptance to arrival were required in a majority of hospitals (81%), the acceptable time interval was inconsistent, varying from 2 to 4 hours (13%) to 24 hours (38%). A mandatory 3‐way recorded discussion (between transfer center staff, and referring and accepting physician) was nearly uniform. Objective clinical information to assist the handoff (ie, current labs, radiology images, history and physical, progress notes, or discharge summary) was available in only 29% of hospitals. Only 23% of hospitals also recorded a 3‐way nursing handoff (bedside‐to‐bedside nursing report). A minority of hospitals utilized their principal EMR to document the transfer process and share incoming clinical information among providers (32%).

Descriptions of the transfer process were conceptually evaluated by the study team, then divided into 5 common themes: acceptance and transport, clinical updates, coordination of care, information availability, and quality improvement (Table 2). Institutions devised novel approaches including providing high bed priority to expedite transit, a dedicated quarterback physician to coordinate safe transfer and uninterrupted communication, electronic transfer notes to share communication with all providers, and a standardized system of feedback to referring hospitals. Several institutions relied on an expect note, which could be a free‐text document or a form document in the EMR. This preserves verbal handoff information that may otherwise be lost if the accepting physician at the time of transfer is not the physician receiving the handoff.

Quality improvement occurred via both internal and external feedback at several institutions. There were two notable mechanisms of internal feedback. Review of recorded physician verbal handoff by department chair occurred if an adverse event involved a transferred patient. An automatic internal review was triggered if a patient was upgraded to a higher level of care within 4 hours of arrival. These advanced mechanisms require vigilance and dedication on the part of the transfer center and physicians involved in the transfer process. External feedback was provided to referring hospitals through both active and passive mechanisms. One advanced health system allowed referring providers to access the patient's inpatient medical record for 1 year and sent a discharge summary to all referring hospitals. Another hospital maintained a sophisticated scorecard, with key measures shared with internal stakeholders and referring hospitals. Some of the metrics tracked included: denials due to insufficient bed capacity, change in bed status within 12 hours of transfer, and duration of stay in the postanesthesia care unit or emergency department awaiting an inpatient bed. This organization also performed site visits to referring hospitals, addressing handoff quality improvement.
DISCUSSION
Standardizing intrahospital handoffs has been shown to decrease preventable medical errors and reduce possible near‐miss events.[6, 10] Interhospital care transitions are inherently more complex due to increased acuity and decreased continuity; yet, there is no universal standardization of these handovers. We found that practices vary widely among tertiary care centers, and the level of transfer center involvement in the verbal and written handoff is inconsistent.
Evidence‐based frameworks to improve healthcare delivery, such as TeamSTEPPS (Team Strategies and Tools to Enhance Performance and Patient Safety), first require an organizational assessment to identify barriers to effective communication.[11] Interhospital transfers offer multiple unique barriers to continuity: physical distance, uncertainty in timing, incongruent treatment goals, disparate information sources, and distractions. This study provides the first step in conceptualizing the unique aspects of interhospital transfers, as well as highlights strategies to improve care coordination (Table 2).
A tailored intervention needs not only to overcome the typical barriers to handoffs such as time constraints, information sharing, and ambiguity in provider roles, but also to overcome multiple systems barriers. Bed management systems add another time‐related variable due to fixed and frequently overburdened bed capacity. Prioritization of transfers depends upon an accurate clinical depiction of patient acuity as well as organizational strategies. For example, neurologic diagnoses are commonly a top priority and are triaged as such, sometimes instead of higher‐acuity patients with other principal diagnoses. The complexity of this process may lead to delays in high‐acuity transfers, and is contingent upon accurate and updated clinical information. Coordinating handovers amidst complex provider schedules is another systems barrier. The commonly adopted 7 on, 7 off model for hospitalists, and shift work for intensivists, may increase the possibility that a transfer occurs across multiple provider changes. Patient follow‐up and closed‐loop feedback are important components of intrahospital handovers, but are much more challenging to implement for interhospital handovers with incongruent information systems and providers.
Programs to improve intrahospital handovers (eg, IPASS) emphasize creating an accurate clinical depiction of a patient using both verbal and written handoffs.[12] This is arguably more difficult over the phone without a concurrent written handoff. Recording of 3‐way physician and nurse handoffs is common, but reviews of recorded conversations are often unavailable or cumbersome in real time. EMR documentation of verbal information exchanged during the handoff is a possible solution. However, there may be legal implications for a transcribed verbal handoff. Furthermore, transfer centers often work with a software program separate from the principal EMR, and documentation in real time is challenging. EMR integration could help reinforce a patient‐centered shared mental model by allowing visualization of lab trends, radiology, vitals, and other documentation during and after the verbal handoff.
Physician‐driven checklist accept tools are another solution. Usually the responsibility of the accepting attending or fellow, this type of document is most useful as a modifiable document in the EMR. Accept tools, such as the one created by Malpass et al., have demonstrated successful shared decision making, and have resulted in fewer emergent procedures and fewer antibiotic changes on arrival.[13] One of the challenges with this approach is the frequency of utilization. In the aforementioned study, the adoption rate of the accept tool was about 70% in a closed university medical ICU, where these types of interventions may be viewed favorably by providers instead of burdensome.[13]
The most consistent finding of this survey was the lack of common processes to improve outcomes. Simple interventions, such as regular clinical updates, documentation of the handoff process, and obtaining objective information early in the process, were inconsistently adopted. Outcomes tracking and feedback are necessary components of team‐based quality improvement. Approximately half of the hospitals surveyed specifically tracked outcomes of transferred patients, and a minority had systems in place to provide feedback to referring centers.
Improving care delivery requires buy‐in from all participants, necessitating engagement of referring hospitals. Interventions such as frequent status updates and providing early documentation have the potential to increase the burden on referring providers when feedback or incentives are not commonplace. Moreover, the referring provider has the option of transferring a patient to a hospital with reduced handoff requirements, creating a disincentive for quality improvement. Quality metrics that incorporate outcomes of transferred patients may be necessary to better align the goals of sending and receiving physicians.
This study was intended to be a qualitative investigation and has some limitations. Any verbal qualitative study has the possibility of misinterpretation of information given by transfer center personnel. A single investigator performed most of the discussions and was able to clarify when needed, providing a degree of consistency, but may also be a source of bias. Categorical answers and a team‐based approach to conceptualizing responses likely minimized this potential bias.
We selected hospitals from the U.S. News and World Report Honor Roll plus additional hospitals chosen based on similarity to our home institutions. This may be a skewed sample and may not represent other major US hospitals and networks. However, we chose to interview large academic tertiary care centers, many accepting more than 1000 patients monthly, as these are likely to be the most proficient at performing transfers, and responses may be generalizable.
CONCLUSIONS
Standardization of information exchange during interhospital transfers does not currently exist. Practices vary widely amongst academic tertiary care centers. There is a paucity of data to support the association of specific processes with patient outcomes. Ultimately, a multicenter study examining the impact of improved information transfer on patient outcomes is warranted, utilizing tracking resources already in place. Optimizing and aligning practices between sending and receiving hospitals may improve interhospital handover efficiency and patient safety.

Descriptions of the transfer process were conceptually evaluated by the study team, then divided into 5 common themes: acceptance and transport, clinical updates, coordination of care, information availability, and quality improvement (Table 2). Institutions devised novel approaches including providing high bed priority to expedite transit, a dedicated quarterback physician to coordinate safe transfer and uninterrupted communication, electronic transfer notes to share communication with all providers, and a standardized system of feedback to referring hospitals. Several institutions relied on an expect note, which could be a free‐text document or a form document in the EMR. This preserves verbal handoff information that may otherwise be lost if the accepting physician at the time of transfer is not the physician receiving the handoff.

Quality improvement occurred via both internal and external feedback at several institutions. There were two notable mechanisms of internal feedback. Review of recorded physician verbal handoff by department chair occurred if an adverse event involved a transferred patient. An automatic internal review was triggered if a patient was upgraded to a higher level of care within 4 hours of arrival. These advanced mechanisms require vigilance and dedication on the part of the transfer center and physicians involved in the transfer process. External feedback was provided to referring hospitals through both active and passive mechanisms. One advanced health system allowed referring providers to access the patient's inpatient medical record for 1 year and sent a discharge summary to all referring hospitals. Another hospital maintained a sophisticated scorecard, with key measures shared with internal stakeholders and referring hospitals. Some of the metrics tracked included: denials due to insufficient bed capacity, change in bed status within 12 hours of transfer, and duration of stay in the postanesthesia care unit or emergency department awaiting an inpatient bed. This organization also performed site visits to referring hospitals, addressing handoff quality improvement.
DISCUSSION
Standardizing intrahospital handoffs has been shown to decrease preventable medical errors and reduce possible near‐miss events.[6, 10] Interhospital care transitions are inherently more complex due to increased acuity and decreased continuity; yet, there is no universal standardization of these handovers. We found that practices vary widely among tertiary care centers, and the level of transfer center involvement in the verbal and written handoff is inconsistent.
Evidence‐based frameworks to improve healthcare delivery, such as TeamSTEPPS (Team Strategies and Tools to Enhance Performance and Patient Safety), first require an organizational assessment to identify barriers to effective communication.[11] Interhospital transfers offer multiple unique barriers to continuity: physical distance, uncertainty in timing, incongruent treatment goals, disparate information sources, and distractions. This study provides the first step in conceptualizing the unique aspects of interhospital transfers, as well as highlights strategies to improve care coordination (Table 2).
A tailored intervention needs not only to overcome the typical barriers to handoffs such as time constraints, information sharing, and ambiguity in provider roles, but also to overcome multiple systems barriers. Bed management systems add another time‐related variable due to fixed and frequently overburdened bed capacity. Prioritization of transfers depends upon an accurate clinical depiction of patient acuity as well as organizational strategies. For example, neurologic diagnoses are commonly a top priority and are triaged as such, sometimes instead of higher‐acuity patients with other principal diagnoses. The complexity of this process may lead to delays in high‐acuity transfers, and is contingent upon accurate and updated clinical information. Coordinating handovers amidst complex provider schedules is another systems barrier. The commonly adopted 7 on, 7 off model for hospitalists, and shift work for intensivists, may increase the possibility that a transfer occurs across multiple provider changes. Patient follow‐up and closed‐loop feedback are important components of intrahospital handovers, but are much more challenging to implement for interhospital handovers with incongruent information systems and providers.
Programs to improve intrahospital handovers (eg, IPASS) emphasize creating an accurate clinical depiction of a patient using both verbal and written handoffs.[12] This is arguably more difficult over the phone without a concurrent written handoff. Recording of 3‐way physician and nurse handoffs is common, but reviews of recorded conversations are often unavailable or cumbersome in real time. EMR documentation of verbal information exchanged during the handoff is a possible solution. However, there may be legal implications for a transcribed verbal handoff. Furthermore, transfer centers often work with a software program separate from the principal EMR, and documentation in real time is challenging. EMR integration could help reinforce a patient‐centered shared mental model by allowing visualization of lab trends, radiology, vitals, and other documentation during and after the verbal handoff.
Physician‐driven checklist accept tools are another solution. Usually the responsibility of the accepting attending or fellow, this type of document is most useful as a modifiable document in the EMR. Accept tools, such as the one created by Malpass et al., have demonstrated successful shared decision making, and have resulted in fewer emergent procedures and fewer antibiotic changes on arrival.[13] One of the challenges with this approach is the frequency of utilization. In the aforementioned study, the adoption rate of the accept tool was about 70% in a closed university medical ICU, where these types of interventions may be viewed favorably by providers instead of burdensome.[13]
The most consistent finding of this survey was the lack of common processes to improve outcomes. Simple interventions, such as regular clinical updates, documentation of the handoff process, and obtaining objective information early in the process, were inconsistently adopted. Outcomes tracking and feedback are necessary components of team‐based quality improvement. Approximately half of the hospitals surveyed specifically tracked outcomes of transferred patients, and a minority had systems in place to provide feedback to referring centers.
Improving care delivery requires buy‐in from all participants, necessitating engagement of referring hospitals. Interventions such as frequent status updates and providing early documentation have the potential to increase the burden on referring providers when feedback or incentives are not commonplace. Moreover, the referring provider has the option of transferring a patient to a hospital with reduced handoff requirements, creating a disincentive for quality improvement. Quality metrics that incorporate outcomes of transferred patients may be necessary to better align the goals of sending and receiving physicians.
This study was intended to be a qualitative investigation and has some limitations. Any verbal qualitative study has the possibility of misinterpretation of information given by transfer center personnel. A single investigator performed most of the discussions and was able to clarify when needed, providing a degree of consistency, but may also be a source of bias. Categorical answers and a team‐based approach to conceptualizing responses likely minimized this potential bias.
We selected hospitals from the U.S. News and World Report Honor Roll plus additional hospitals chosen based on similarity to our home institutions. This may be a skewed sample and may not represent other major US hospitals and networks. However, we chose to interview large academic tertiary care centers, many accepting more than 1000 patients monthly, as these are likely to be the most proficient at performing transfers, and responses may be generalizable.
CONCLUSIONS
Standardization of information exchange during interhospital transfers does not currently exist. Practices vary widely amongst academic tertiary care centers. There is a paucity of data to support the association of specific processes with patient outcomes. Ultimately, a multicenter study examining the impact of improved information transfer on patient outcomes is warranted, utilizing tracking resources already in place. Optimizing and aligning practices between sending and receiving hospitals may improve interhospital handover efficiency and patient safety.

Transitions of care are major sources of preventable medical errors. Incomplete or inaccurate communication during handoffs is the root cause of many adverse events.[1] In a prospective study, adverse events were found to occur during interhospital transfer up to 30% of the time.[2] Furthermore, patients subject to interhospital transfer have longer length of stay and higher inpatient mortality, even after adjusting for mortality risk predictors.[3] Standardizing intrahospital handoff structures and communication practices has been shown to reduce medical errors.[4, 5, 6] Interhospital transfer is an understudied area among the transitions of care literature. Little is known about institutional variations in the process of information transfer and its association with patient outcomes. Although it is challenging to ascertain the total burden of transferred patients, it has been estimated that 1.6 million inpatients originated at another facility.[7] Additionally, approximately 5.9% of admissions to a representative sample of US intensive care units (ICU) originated from other hospitals.[8] Patients are transferred between hospitals for multiple reasons beyond medical necessity, for example, to adjust for patient preferences, bed availability, and hospital staffing patterns. This creates a setting in which complex and often critically ill patients are subject to variable and sometimes ambiguous handoff processes.[9]
This survey of 32 tertiary care centers in the United States was undertaken to identify common practices in communication and documentation during interhospital patient transfers. Additional goals were to understand the structure of the handoff process, the role of the transfer center, and how electronic medical records (EMR) and interhospital communication play a role in this care transition. Subsequently, common challenges in coordinating interhospital transfers were identified to provide a conceptual framework for process improvement.
METHODS
Survey Process
The survey was initiated in September 2013 and concluded in September 2015, and was designed to quantify patient volume and identify common as well as unique practices to improve communication across the transfer process. The respondents were transfer center directors or managers, typically with a nursing background. Mass e‐mail generated a very poor response rate and did not allow for discussion and clarification of responses. The strategy was then modified to contact individual institutions directly. The survey was performed via phone whenever possible. Figure 1 represents purposeful sampling conducted on 2 different groups of hospitals. These hospitals represent a convenience sample of institutions from a nationally ranked list of hospitals as well as others comparable to our own institutions. Hospitals were selected based on status as academic tertiary care centers with roughly similar bed sizes (600). Several were selected based on similar EMR capabilities. Geographic diversity was also taken into account. Thirty‐two academic tertiary care centers were ultimately included in the survey. Data were entered into a survey form and deidentified. The RutgersRobert Wood Johnson Medical School Institutional Review Board approved this study.
Survey Content
Qualitative and quantitative data were collected by the study team. Data included number and origin of transfers (including those from inpatient facilities and emergency departments), staff characteristics, transfer process, documentation received prior to transfer, EMR access and type, outcomes, and clinical status tracking (see Supporting Figure 1 in the online version of this article for the complete survey tool).
Measurement and Data Analysis
Descriptive statistics are presented in unweighted fashion as a number and percentage for dichotomous variables, or a numeric range for ordinal variables. When a range was given by survey participants, the lower end of the range was used to calculate the population median. Several institutions surveyed were unable to provide specific numeric values, but instead cited how many requests for transfer they received either daily or monthly; these were omitted from the demographics analysis.
Respondents also provided a description of their overall triage and acceptance process for qualitative analysis. Unique strategies were identified by the study personnel at the time of each interview and amassed at the end of the interview period. These strategies were then discussed by the study team, and separated into categories that addressed the main challenges associated with interhospital transfers. Five general tenants of the transfer process were identified: acceptance and transport, need for clinical updates, provider handoffs and coordination of care, information availability, and feedback.
RESULTS
Based on a survey question asking respondents to estimate the total number of interhospital transfers received per month, the annual burden of patients transferred into these 32 hospitals represented approximately 247,000 patients yearly. The median number of patients transferred per month, based on a point estimate if given or the lower end of the range if a range was provided, was 700 (range, 2502500). On average, 28% (range, 10%50%) were transferred directly to an ICU, representing approximately 69,000 critically ill patients. A majority of hospitals polled (65%) received patients from more than 100 referring institutions, and a minority (23%) identified EMR interoperability for more than a quarter of the sending facilities. The overall acceptance rate ranged from 50% to 95%.
Table 1 represents common transition elements of participating institutions. Thirty‐eight percent of hospitals utilize a critical caretrained registered nurse as the initial triage point of contact. The process and quality controls for coordinating transfers from outside hospitals were highly variable. Although clinical updates from acceptance to arrival were required in a majority of hospitals (81%), the acceptable time interval was inconsistent, varying from 2 to 4 hours (13%) to 24 hours (38%). A mandatory 3‐way recorded discussion (between transfer center staff, and referring and accepting physician) was nearly uniform. Objective clinical information to assist the handoff (ie, current labs, radiology images, history and physical, progress notes, or discharge summary) was available in only 29% of hospitals. Only 23% of hospitals also recorded a 3‐way nursing handoff (bedside‐to‐bedside nursing report). A minority of hospitals utilized their principal EMR to document the transfer process and share incoming clinical information among providers (32%).
