Abstract
Background Patient portals, and the secure messaging feature in particular, have been studied in the outpatient setting, but research in the inpatient setting is relatively less mature.
Objective To understand the topics discussed in secure messaging in the inpatient environment, we analyzed and categorized messages sent within an inpatient portal.
Materials and Methods This observational study examined the content of all secure messages sent from December 2013 to June 2017 within an inpatient portal at a large Midwestern academic medical center (AMC). We analyzed a total of 2,598 messages, categorizing them by sender (patient, family, or care team member), type, and topic, and conducted a descriptive analysis of categories and an examination of code co-occurrence.
Results Patients were the most frequent message senders (63%); family members sent the fewest messages (10%). We identified five types of messages: Alert/Request; Thanks; Response; Question; and Other (typo/test message). Patient messages included Alerts/Requests (38%), Questions (31%), Statements of Thanks (24%), Response (1.2%), and Other (5%). We also identified 14 nonmutually exclusive message topics: Medication; Procedure/Treatment Plan; Schedule; Pain; Results; Diet; Discharge; Non-Medication Questions; Provider Requests; Symptoms; Custodial; Technical Issues; Potential Error; and Contact Information. Patient message topics most commonly discussed Symptoms (18%), Procedure/Treatment Plan (14%), or Pain (12%).
Conclusion Our analysis of secure message content suggests certain message types and topics such as Alerts/Requests and Questions about symptoms and treatment plans are particularly important to patients. These findings demonstrate that both patients and family members utilize the secure messaging function to engage in the care process by posing questions, making requests, and alerting staff to problems. As this technology is implemented in additional facilities, future work should examine how use of secure messaging may be influenced by factors including patients' demographics, reasons for hospitalization, and length of stay.

Background and Significance
In the outpatient setting, patient portals have been linked to improved patient outcomes and disease management[1] [2] [3] as they have increasingly been integrated into the delivery of care.[4] [5] By offering patients easy access to their health records, the ability to schedule and view their appointments, laboratory and test results, access to educational materials, and a way to communicate with providers, portals may facilitate patient engagement and increase many collaborative aspects of health care encounters.[6] [7] However, challenges may exist in using a portal, particularly for patients with chronic illness making attention to design choices critical.[8] [9] [10] [11] Communication between the patient and their care team has been an area of particular interest, with direct engagement through portal communication a component of meaningful use standards set forth to incentivize implementation and use of electronic health records.[12] [13]
Patient portals, and the secure messaging feature available within those portals in particular, have the potential to encourage a greater sense of trust in providers.[5] While much of the research on patient communications through portals has occurred in the outpatient setting,[12] [14] [15] [16] [17] [18] [19] study of inpatient portals containing this function has been limited.[20] This shift in context may be of importance, however, in how these tools are both perceived and used. Chen et al describes three main benefits of outpatient secure messaging including: asynchronous communication, the ability to discuss sensitive subjects with greater privacy, and the ability to retain messages to review later.[21] While existing outpatient coding schemes may inform the analysis of messages sent in the inpatient environment, given the nascent stage of inpatient secure messaging, it is unclear whether these same benefits apply to inpatient portals. In addition, while in the hospital, patients may use a portal designed for the outpatient environment to send messages to providers who care for them in the outpatient environment. However, outpatient portals do not allow communication with the team caring for them in the hospital. In addition, research about the inpatient environment suggests that hospitalized patients may have different health information technology (HIT) needs compared with patients in outpatient settings. For instance, Prey et al identified important facilitators of patient engagement in the inpatient setting including providing patient-specific education and the presence of additional communication opportunities associated with that environment.[22] Thus, both the members with whom a patient communicates and the patient HIT needs may differ in the inpatient and outpatient environments.
Early research on inpatient portals has been limited to studies focused on either specific conditions or smaller-scale studies assessing usability and satisfaction.[23] [24] [25] [26] [27] Collins et al conducted a mixed methods analysis of stakeholder perspectives related to inpatient portal use and reported that patients valued access to an inpatient portal.[4] In another study, Woollen et al identified unmet patient information needs in the hospital setting that inpatient portals can provide, such as easy access to laboratory results.[28] Yet given the novelty of this technology, researchers note that we currently lack understanding both about the optimal inpatient portal experience and how patients and providers can maximize inpatient portal use.[4] [22]
Differences between inpatient and outpatient contexts are particularly relevant when considering the secure messaging feature of patient portals. One prior study of the content of secure messages sent within the outpatient environment used automated classifiers and natural language processing, and reported that patients most frequently used the portal tool to seek medical information, send social messages, or elicit logistical and clinical information.[29] In another study, Shimada et al coded secure messages sent to primary care providers via an outpatient portal and found that they were most frequently transactional in nature, involving requests for medication refills and questions about scheduling.[30] However, needs specific to hospitalized patients may be appreciably different in this context and merely providing portal functions in the inpatient environment similar to those available in outpatient settings may be insufficient. Hospitalization may serve as a cue to action, increasing the patient's focus on their health and potentially increasing their willingness to use a portal to engage in their care.[5] [31] [32] Secure messaging in the inpatient setting may also offer an additional benefit to families who are not always present when the care team is in the patient's room. Using this tool, family members can monitor their loved one's condition, ask questions of the care team, and provide information to the care team.[33] Further, in the outpatient environment, a patient's relationship with their physician has been found to be an important predictor of use of secure messaging[34] [35] [36]; however, hospitalized patients may have a different experience. Inpatients typically see multiple providers during a single hospital stay, some of whom may be new to the patient. Without established relationships with these providers, patients' willingness to send secure messages in the inpatient environment may be impacted. This new technology in the inpatient environment thus introduces a new avenue for communication between patients or family members and care team members and raises new questions about how and by whom this tool is used.
#
Objective
To date, little is known about secure messaging in the inpatient environment. We undertook a mixed methods study of secure message usage within the inpatient portal implemented in a large academic medical center (AMC) to develop an understanding of how secure messages are used and examine this use in the context of inpatient care. Our study was designed to explore how patients and care team members use the secure messaging feature by examining the content of individual messages and categorizing them by sender, type, and topic. Understanding the secure messaging function in the inpatient setting can help to inform future efforts to support patients' use of inpatient portals as well as help hospitals prepare for this new form of communication with their hospitalized patients.
#
Materials and Methods
Study Design
This observational study examined the content of secure messages sent within an inpatient portal across a large Midwestern AMC. Messages were examined both qualitatively and quantitatively to permit both categorization and descriptive analysis of message sender and message content.
#
Study Setting
This AMC provides health services across the continuum of care at 7 hospitals and 53 ambulatory care locations, including 30 community-based clinics. The AMC implemented MyChart Bedside, an inpatient portal developed by Epic Systems (Verona, Wisconsin, United States) that offers a secure messaging feature, across the cancer hospital and labor and delivery units in late 2013. This was followed by implementation across all general hospital units in the AMC in a staged rollout that began during the summer of 2016.[37] The MyChart Bedside application is made available to inpatients on tablet computers that are provisioned upon admission. Patients who are English-speaking, over 18 years of age, nonprisoners, and have no cognitive impairments are offered a tablet for use during their hospital stay.
Patients and family members can send messages via the MyChart Bedside portal with messages going to all members of the care team assigned to that patient. In addition, care team members can initiate messages to the patient, which the patient will be able to view upon opening the application. Policies for care team members responding to messages, such as which team member responds and how frequently team members must check their messages, are established at the unit level and vary across the health system. Further, across the health system, care team members are able to respond electronically or in-person to the patient; the health system does not require an electronic response or documentation of an in-person response.
#
Study Data
All inpatient secure messages sent between December 2013 and June 2017 across the 7 hospitals of the health system (n = 2,599) were provided to the research team via secure link from the AMC's Information Warehouse. Data were stored in a secure directory accessible only to the research team and requiring institutional credential sign-in. Messages were deidentified and not linked to any patient information for the analyses we conducted in this study.
#
Qualitative Analysis
A coding team consisting of three experienced coders (C.S., J.V., and J.H.) jointly reviewed 300 messages to develop a preliminary coding dictionary based on sender (originator of the message), message topic (issues addressed in the message), and message type (goal of the message). Emergent codes were proposed and discussed as the preliminary coding progressed.[38] Then, following the methods of thematic analysis outlined by Constas, two coders (C.S. and J.V.) each coded the same 200 messages using the preliminary coding dictionary in increments of 50 messages until 100% agreement between coders was reached. Frequent discussions between the two coders enabled identification of messages in which coding did not align and differences were resolved so that consensus about the codes and a final coding dictionary was achieved. The same two coders then each coded half of the remaining 2,399 messages using the finalized dictionary, continuing to meet throughout the process to ensure agreement in coding. The qualitative analysis software Atlas.ti (version 6.0) was utilized to facilitate the coding process.[39]
Coders categorized messages on three dimensions: sender, type, and topic. Message sender was first identified by the source recorded in the portal log file output (e.g., patient vs. care team member). Care team members were identified in the file name by their role on the care team (e.g., physician, nurse, patient care associate). Our analysis then further distinguished sender reading each message and determining whether the message was sent by the patient using personal pronouns (e.g., I have a question for my doctor) or identifying oneself by name (e.g., this is John Smith) versus those sent from the patient's account but clearly originating from a patient's family member by referring to the patient by role (e.g., my mom's medications) or by name (e.g., John's blood pressure). Message type and topic were determined by reading each message determining the appropriate code. All messages were assigned a type categorizing the intent of the message, with more than one type possible in a single message. Message topics described the specific issue being expressed in the message. Individual messages could contain more than one topic. Type and topic categories emerged from the message content.
#
Quantitative Analysis
We conducted a descriptive analysis of the frequency of messages by sender, type, and topic. We also examined the number of messages sent and number of topics addressed per message by sender. Within topic, we reviewed the co-occurrence of codes to understand which topics were discussed together in the same message. Co-occurrence was calculated for each message topic as the number of messages with the focal topic of each calculation plus each other topic individually, divided by the total number of messages with the focal topic of the calculation.[40] For example, to determine the co-occurrence of Treatment Plan with Symptoms (focal topic), we utilized the following formula:

Results
Secure Message Senders
We found that the majority of patients (74.3%) sent one message during admission, and fewer than 3% sent over 5 messages. Most messages, 63%, were sent by patients, with family members sending the fewest messages, at 10%. Within care team categories, nurses sent the majority of messages. We present this overall distribution of messages by senders in [Table 1].
#
Secure Message Types and Topics
Our qualitative analysis identified five types of messages: Alert/Request, Thanks, Response, Question, and Other. [Table 2] provides a definition of each message type along with an example of that type of message. Because secure messages are considered protected health information, the examples included in this table are fictional.
Abbreviation: MRI, magnetic resonance imaging.
We also identified 14 distinct topics included in the secure messages as shown and defined in [Table 3]. As with message types we presented above, the examples we included are fictional. Also, as previously noted, messages could contain more than one topic. However, 29% of messages were not assigned a topic due to their content. These messages were typically Thanks, Response, or Other.
Abbreviation: MRI, magnetic resonance imaging.
Messages by patients typically addressed only 1 topic, and we found a maximum of 5 topics in a single message. Family members addressed slightly more topics per message, with an average of 1.5 topics and a maximum of 5 topics covered. Care team members included 1 topic per message on average, with a maximum of 4 topics in a single message.
#
Secure Messages Types, by Sender
We found that types of messages varied by sender. As [Table 4] shows, most patient messages were Alerts/Requests (40%), Questions (28%), or Thanks (25%). Family members sent messages that asked Questions (45%) or Alerted the care team/made a Request (41%). The majority of care team messages were Responses to patient or family messages (74%), followed by Responses to patient Thank you messages (20%).
#
Secure Message Topics, by Sender
[Fig. 1] shows the percentages of messages sent by each sender on each message topic. The most common message topic from patients was related to discussing Treatment Plan, followed by Medication and Symptoms. Very few patient messages were related to Custodial issues or Potential Error Identification. Family members sent messages most frequently about the same three topics. Messages from the care team also most frequently focused on the Treatment Plan, but messages related to the provider coming to see the patient were the second most frequent topic addressed by the care team.

#
Code Co-occurrence
To gain a thorough understanding of secure messaging, we also examined how frequently message topics occurred concurrently. The results of our code co-occurrence analysis are presented in [Fig. 2] which shows the percentages of co-occurring message topics, by topic category. We found that among messages sent related to Potential Error Identification, 54% addressed Medication, 19% addressed Procedure/Treatment Plan, and 12% discussed Symptoms. However, of the messages that related to Medication, only 4% were also related to Potential Error Identification; most pertained to Pain (34%), Symptoms (28%), or Procedure/Treatment Plan (27%). Messages related to Pain were most frequently also related to Medication (58%) and Symptoms (46%). Technical Issues were infrequent but most commonly co-occurred with messages about Diet (28%) and Results (17%).

Discussion
While other researchers have examined the content of secure messages exchanged between providers in the inpatient setting,[41] this study is the first to analyze secure message content exchanged between patients or family members and care team members exclusively through an inpatient portal, a tool increasingly being introduced in hospital settings.[17] [18] Outpatient portals have seen an increase in secure messaging over time, with messages often related to appointments and medication refills. Our findings suggest that hospitalized patients use the secure message feature differently than in the outpatient setting, with inpatients using the feature mainly to discuss their care plan and ask questions. We found that just over one-quarter of patients sent more than one message during their admission, suggesting acceptance of this portal feature, even in this early stage of inpatient portal use. In addition, we found that patients, families, and care team members in our study used the secure messaging function differently with respect to both message type and topic. For instance, patient messages focused predominantly on health questions, logistical/scheduling concerns, and technical problems, while messages from family members frequently alerted the care team to symptoms the patient was experiencing or asked for additional information about symptoms or the procedure/treatment plan. Notably, timely access to health information, such as explanation of results and clarification of medication schedules, is particularly relevant to the inpatient environment, and may decrease patient and caregiver anxiety,[27] thus the availability of this information via a portal may be an important opportunity to increase the patient-centeredness of care delivered, an important goal of health care organizations.
Many messages from both patients and family members in our study involved asking questions (28 and 45%, respectively), providing early evidence that patients are willing to use this communication modality to seek health information. Moreover, secure messaging in the inpatient environment allows family members to communicate directly with the care team asynchronously. Prior to the availability of this technology, family members might leave notes at the patient's bedside to which the care team could respond later, or they might attempt to connect with the care team via telephone. The secure messaging function, however, allows family members to send a message while they are visiting the patient and receive a response when they next visit and use the inpatient portal. While other studies suggest mixed results related to whether providing health information through an inpatient portal facilitates or replaces in-person communication,[28] [42] our findings demonstrate that both patients and family members may use the secure message function to ask questions and this may help them to remain engaged in the care process. Further, in the outpatient setting, patients viewed secure messaging as an important opportunity to communicate with their providers at a time that was convenient for them and that offered a record of the communication[5] [21]; we expect similar benefits would be perceived by caregivers in the inpatient environment as well.
While each patient-generated message in our study was sent to all members of the patient's care team, nurses were the most frequent respondents to these messages. This finding may reflect the typical pattern of in-person communication during hospitalization as nurses tend to have the most frequent contact with patients and therefore are well-positioned to respond to patient messages. Nonetheless, 25% of messages from the care team were sent by other team members, including physicians. Future research should monitor patterns in care team responses as both patients and care teams gain greater experience with secure messages in the inpatient setting. Moreover, studies in the outpatient setting document provider concerns about the possible increase in workload from secure messages in the outpatient setting,[18] [43] and we might expect similar concerns among hospital care team members. As secure messaging in the inpatient environment increases in use, future studies should explicitly consider issues such as how secure messaging impacts provider time and workflow and how best to train both patients and providers in using this type of tool.[44]
Our code co-occurrence analysis highlighted patterns that may be useful for understanding which topics are most important to patients, as well as providing insight into which features of the inpatient portal might need improvement. Our analysis found that half of all messages referring to procedure/treatment plan co-occurred with message topics about pain and symptoms. This suggests patients may be utilizing the secure messaging feature to keep their providers better informed and updated on their health status, which may alter their treatment plan.
Although messages reporting potential errors were infrequent, the majority of these types of messages addressed possible medication errors, lending support to the idea that inpatient secure messaging may present another avenue to explore in the context of patient safety improvement efforts.[45] [46] In addition, patient technology-related questions most frequently focused on challenges with using the food ordering function and with viewing laboratory test results, suggesting a need to improve these features and perhaps enhance training around their use.[11] [21] [47]
Secure messaging in the inpatient environment, as in the outpatient setting, has the potential to improve patient care by increasing patient engagement in their care.[6] [22] [48] [49] [50] The secure messaging function also enables patients to retain an electronic record of their communications with care team members. In practice, the availability of this new asynchronous communication avenue in the hospital context may provide the opportunity to enhance patient care by improving patient and family understanding of the patient's condition and treatment plan, facilitate recognition of changes in symptoms particular to that patient, and even assist with postdischarge treatment by allowing caregivers who may be caring for the patient after discharge another venue for asking questions.
As Collins et al note, however, there is a need to understand how use of the secure messaging feature enhances in-person communication but does not replace it.[4] Patient portal technology is becoming more integrated within the inpatient environment and understanding how patients, families, and care team members are using the secure messaging feature to communicate can enhance our ability to answer patient questions and respond to patient needs. Our study results thus help to improve the understanding of the use and potential for this portal feature in the inpatient environment and may inform future interventions focused on improving patient engagement in the inpatient setting.
Limitations
Our study faces some important limitations. First, our study offers insight based on secure messages sent within a single AMC that was an early adopter of an inpatient portal. As a result, our study findings may have limited generalizability to the broader population of health care organizations and later adopters of this tool. As inpatient portals are implemented in more hospitals, researchers should examine how the secure message types and topics evolve.
Second, this study utilized deidentified data that limited our ability to match messages with patient demographic and clinical information. Our emphasis in this study was on describing how hospitalized patients use secure messages. However, investigating the effect of patient characteristics on message attributes remains an intriguing area for future inquiry.
#
#
Conclusion
Inpatient portals are increasingly available and offer many features to hospitalized patients and their families, particularly the ability to communicate via secure messaging. We found that patients, families, and care team members are willing to use secure messages as an additional means of communication, and we characterized the content of the messages sent, describing topics of importance to patients, families, and care team members. As this technology is increasingly implemented in the inpatient environment, future work should examine how patterns of use evolve, as well as how use may be related to patient outcomes such as examining whether greater use of the message feature is related to improved understanding of discharge instructions or fewer readmissions.
#
Clinical Relevance Statement
This study provides a preliminary framework to help health care systems and clinicians better understand how to engage patients using secure messaging in the inpatient environment. We found that patients and family members are willing to use secure messaging in a variety of ways, thus requiring increased attention by hospitals and health systems to understand how best to support this function. Understanding the types of messages patients send and topics that are important to patients can help hospital clinicians better adapt to this new technology as it becomes more frequently used in the inpatient setting.
