Abstract
Background:
Real-time videoconferencing technology such as clinical video telehealth (CVT) offers a means to reach patient populations who face limited access to healthcare. The Veterans Health Administration has invested in CVT to improve care access for U.S. military veterans with spinal cord injuries and disorders (SCI/D); however, no studies have assessed the factors that influence implementation of this technology in clinical practice for individuals with SCI/D.
Introduction:
Guided by a sociotechnical perspective, the purpose of this study was to identify factors that influence implementation of CVT for veterans with SCI/D.
Materials and Methods:
We conducted semistructured telephone interviews with 40 healthcare providers who use CVT to deliver services to veterans with SCI/D.
Results:
Factors related to workflow and communication were widely reported as implementation barriers. Coordinating logistics for CVT appointments was challenging, and effective communication between CVT team members across facilities was considered crucial. Providers also cited factors related to technical infrastructure, people, and organizational features, including the need for appropriate equipment, space, personnel, and support for using CVT equipment.
Discussion:
The implementation of CVT in the care of veterans with SCI/D was influenced by an interrelated set of social and technical factors. Key among them were social factors related to people, workflow, and communication, given that CVT supports healthcare teams interacting remotely in real time.
Conclusions:
CVT implementation requires teams working together to negotiate a complex, distributed process across multiple sites. Such complexity places a premium on teamwork and communication among healthcare teams before, during, and after a CVT encounter.
Introduction
Spinal cord injuries (SCI) can lead to substantial physical, psychological, and social challenges. 1 –3 In the United States (U.S.), approximately 276,000 individuals are living with SCI and approximately 12,500 new cases are reported annually. 4,5 These individuals require frequent, specialized, and interdisciplinary healthcare to address impairments to mobility and autonomic functions, 6,7 as well as secondary complications, including bowel or bladder dysfunction, 8 pressure ulcers, 9 pain, 10 depression, and other comorbidities. 11 –14 Despite these complex needs, individuals with SCI face significant challenges accessing care. 15,16 Delivery of care to individuals with SCI in rural settings is particularly challenging given transportation and mobility issues and limited available services. 17 –19 For these reasons, expanding access to care is important to improving outcomes for this population. 17,20,21
To improve care access for U.S. veterans with spinal cord injuries and disorders (SCI/D), the Veterans Health Administration (VHA) SCI/D System of Care has adopted the use of Clinical Video Telehealth (CVT), a real-time videoconferencing technology, to provide healthcare services. The VHA SCI/D System of Care is organized as an integrated hub-and-spoke network. Use of CVT is designed to optimize access for individuals with SCI/D who obtain care at local VHA care facilities (i.e., spoke sites) by connecting them with providers at VHA SCI/D Centers (i.e., hub sites). 22,23
Evidence shows that use of CVT in SCI/D care produces similar outcomes compared with in-person visits, and is associated with high levels of patient satisfaction. 24 –27 Recent studies have also described issues that are unique to implementing new practices in SCI/D care settings 28,29 ; these findings suggest a need to assess factors that may influence CVT implementation specifically in SCI/D care. The purpose of this study was to examine, from a sociotechnical perspective, the range of factors that influence implementation of CVT across VHA SCI/D facilities. We used Sittig and Singh's sociotechnical model, 30 developed to advance knowledge of the social and technical factors that shape implementation and evaluation of health information technology (HIT) interventions, to guide our evaluation (Table 1). To our knowledge, the implementation of CVT in SCI/D care represents a novel context in which to apply the sociotechnical model. 30

Materials and Methods
We conducted a qualitative, formative evaluation using semistructured telephone interviews. Interviews were conducted between January and July 2014. This study was approved by VHA Institutional Review Boards.
Participants
We used a purposeful sampling strategy to identify healthcare team members based at spoke sites that use CVT technology within the VHA SCI/D System of Care. We recruited participants from a list of 155 providers from 69 spoke sites, all of whom were invited to complete a semistructured interview.
Procedure
We e-mailed providers to inform them of the opportunity to participate and sent a follow-up e-mail a week later with a formal invitation. Verbal consent was obtained at the beginning of each participant telephone call. Before the start of the interviews, participants were asked to complete a demographics questionnaire. Two authors trained in qualitative methods conducted the interviews. Interviews lasted approximately 45–60 min, were audio-recorded, and transcribed verbatim.
Measures
We designed a semistructured interview guide with open-ended questions and corresponding probes. The guide was reviewed by clinicians, refined, and pilot tested in a provider interview before data collection. Interview topics included the following: (1) provider teams and roles, (2) process of using CVT; (3) inhibiting and facilitating factors to implementing CVT; and (4) general perceptions of the technology. Sample interview questions are listed in Table 2.

Data Analysis
Descriptive statistics were used to analyze questionnaire data. Interview transcripts were loaded into NVivo (QSR International Pty Ltd. Version 8.0, 2008) and analytic work proceeded through thematic content analysis, which involves deriving concepts from data and comparing them with other data to facilitate meaningful categorization. 31,32 We initiated coding with a list of basic categories from the interview topics (Table 2). Within these categories, emergent subcodes were identified and defined in a codebook. Two of the authors reviewed a subset of the transcripts independently and then met to compare emergent subcodes. They then coded the entire data set independently using the categories and subcodes identified, refining codes as necessary. The initial list of basic codes and subcodes became saturated after coding 10–12 transcripts. The eight dimensions of the sociotechnical model 30 were applied to the data set after this initial analysis. Two authors independently categorized codes and subcodes from the codebook within the most representative dimensions of the model. Consensus was obtained between the two authors and subsequent discussions regarding interrelatedness of the dimensions were captured in memos.
Results
As shown in Table 3, 40 providers representing 33 different SCI/D care facilities participated; the sample comprised primarily social workers, nurses, and physicians. We used the eight sociotechnical model dimensions 30 to organize and describe the factors identified through our analysis that influence CVT implementation for veterans with SCI/D. The model dimensions are recognized as interdependent; we presented factors within the most representative dimension. Of note, factors related to external rules, regulations, and pressures are not discussed as they did not emerge in the interviews. Representative participant quotations are presented in Table 4.

Hardware and Software Computing Infrastructure
Several challenges reflecting the technical requirements for implementing CVT, including appropriate equipment, bandwidth, and physical space, were reported. Providers mentioned equipment failure as a problem. A related issue was limited bandwidth, which occasionally resulted in dropped calls or delayed audio/video. Given the limited space available in most care settings, identifying sufficient space for CVT equipment was a common challenge across sites. To overcome these issues, providers described the importance of using up-to-date equipment and working with other clinics outside of SCI/D to locate space for CVT equipment and appointments.
Clinical Content
Factors related to clinical content extended beyond CVT storage capacity to encompass the use of CVT for sharing clinical information. Several providers emphasized the importance of establishing correct CVT clinic stop-codes (i.e., identifiers used to denote workload for outpatient encounters, inpatient appointments in outpatient clinics and inpatient billable professional services). As participants explained, incorrect clinic stop-codes can have unintended consequences for workload credit and healthcare reimbursement.
Conducting appointments over CVT also presents unique challenges to gather clinical information. A common concern was the perceived limits to evaluate physical symptoms over CVT. Many providers found it difficult to assess complaints (e.g., wounds) without being physically present to use their own hands. However, many reported the benefit of using CVT to consult specialists outside their facility to gain insight into clinical issues beyond their expertise.
Human Computer Interface
Providers commonly reported that the more they interacted with the CVT technology, the more confident they became with powering the equipment on and off, adjusting the camera, placing video calls, and speaking with remote clinical teams over a CVT screen. The same was reported to be true for individuals with SCI/D. Some providers encountered initial hesitance from individuals with SCI/D, which they mostly attributed to patients' uncertain feelings about the new technology. Once providers explained what CVT was and how it worked, however, most said that patients were comfortable having a CVT encounter.
People
Many providers stressed the importance of having adequate staff to address the steps involved in implementing CVT services. Many found it difficult to execute a CVT encounter without staff who possessed knowledge of the equipment and related technical skills. They emphasized the importance of having at least one on-site CVT champion, who could be a telehealth coordinator, nurse, social worker, IT administrator, or anyone who can help coordinate CVT activities. Advocating for CVT use, scheduling CVT appointments, preparing CVT equipment, obtaining special equipment, and/or distributing CVT-related work to prevent providers from getting overwhelmed were all tasks identified in the purview of a CVT champion.
An essential aspect of this dimension of the sociotechnical model is the availability of training to overcome user-related problems with a given technology. The VHA has established standard online training for providers who use CVT. Although the providers in our sample generally perceived this training as informative, they suggested supplementing it with in-person, hands-on training activities. Many reported the benefits of face-to-face contact with on-site and off-site staff who know how to use CVT. In particular, one provider discussed the benefit of having experienced providers share their knowledge with newer providers on using CVT technology. Furthermore, providers indicated that they would value “refresher” trainings, given the many details that must be tracked, especially when initiating CVT use.
Workflow and Communication
Implementing CVT technology generally involves two main processes—coordinating logistics surrounding CVT appointments and interacting over CVT to deliver services. A commonly reported problem among participants was scheduling encounters. Scheduling can be difficult because appointment times depend on the availability of CVT equipment, space, patient with SCI/D, and multiple providers at multiple sites, some of which may be in different time zones. Other activities include setting up equipment and confirming the transfer of information between sites before and after encounters. Coordinating these activities often involves multiple people from participating facilities.
Another prominent issue described by providers is the relationship between the success of CVT encounters and communication among team members at participating facilities. Participants unanimously agreed that ongoing communication across facilities is essential. This communication must span multiple levels, including troubleshooting technical issues and determining a process for sharing patient medical information (e.g., medical history and symptoms) in a timely manner. Providers reported that CVT appointments run more efficiently when patient medical information is shared between facilities in advance. Some described the benefit of holding team conversations over teleconference or e-mail before CVT appointments to communicate that information and prepare for a focused visit.
Also of importance is the actual interaction over CVT to access and deliver the needed services. Many providers emphasized the importance of being “on the same page” with remote team members and having the necessary information to make informed decisions as a team. Many providers reported tremendous benefit from seeing remote team member faces and expressions, which helped make the connection more personal. The importance of establishing relationships with providers across facilities to support the CVT encounter was frequently discussed. When providers were not familiar with other team members, issues of trust were potentially exacerbated over CVT. Establishing rapport with team members during CVT training and encounters was recognized as a means to support team building and development of trust. The more team members at local and distant facilities interacted with each other, the more chances there were for them to know and become comfortable with each other.
Internal Organizational Policies, Procedures, and Culture
Leadership from multiple organizational levels influenced how CVT was implemented in SCI/D care. At the overall system level, VHA leadership was responsible for providing funding for facilities to obtain CVT equipment. At the facility level, buy-in from the hospital director, SCI/D Center Chief, and leaders of the healthcare team facilitated CVT uptake and use. Providers noted that support from VHA leadership was crucial to implementing CVT.
System Measurement and Monitoring
Many providers discussed the effectiveness of CVT for promoting access to healthcare services. Most explained that a tremendous advantage of CVT is the convenience offered to individuals with SCI/D, and that the technology has enhanced access for many who may have previously gone without assessments or treatments because of geographic and distance-related barriers. The option to travel to a nearby VHA facility as opposed to an SCI/D Center was reported by providers as an effective solution to save veterans hours of travel time. Providers explained that CVT encounters can be more efficient because the entire healthcare team is present along with the patient and sometimes his/her family, allowing for questions and concerns to be addressed in real time.
Finally, using CVT as part of SCI/D care may increase patient engagement and improve outcomes. Providers reported that CVT allows them to intervene early and meet more frequently with individuals with SCI/D, facilitating preventive, seamless care. They also explained that CVT use empowers individuals with SCI/D to engage in healthcare decision-making and connect with their healthcare team, as a whole, more frequently.
Discussion
This study is the first to examine perspectives of healthcare providers regarding implementation of CVT to evaluate and treat veterans with SCI/D. Application of the sociotechnical model highlighted a range of factors that influence CVT implementation while accounting for the complex interactions of HIT and the SCI/D care context.
Despite several benefits of utilizing CVT in SCI/D care, the process of implementing this technology is complicated, given the many steps and people it involves. The required coordination and effective communication between local and remote team members at both facilities were seen as crucial for implementation (workflow and communication dimension of the sociotechnical model). Insufficient resources were identified as an additional challenge. Providers reported the need to have appropriate equipment, space, personnel, and support for setting up and using CVT equipment at both facilities. These resources span several sociotechnical model dimensions, including hardware and software computing infrastructure, people, and internal organizational policies. Addressing such resource needs can improve the implementation of CVT. These results are consistent with a recent systematic review of knowledge translation and implementation change in SCI/D, which emphasized insufficient resources (e.g., funding, personnel) and communication as key barriers to implementation, and communication among team members as a key facilitator. 29 Teamwork and effective communication throughout the healthcare setting are essential for providing efficient, quality care to optimize patient outcomes. 33,34 The Institute of Medicine emphasizes the importance of teamwork stating that it involves “changing the existing construct of care delivery to one of open collaboration with patients, team-based care [and] delivery of care within and outside the hospital” (p. B18). 35 Providing SCI/D care has been recognized as a team-based enterprise for well over 40 years. Healthcare organizations, especially those using CVT to provide care for patients with SCI/D, may benefit from developing teamwork at multiple levels—across organizations, providers, patients, and their families—to deliver high-quality care. 36
Many providers in this study highlighted the importance of leadership support to initiate and sustain use of CVT technology, and the value of having a dedicated person to coordinate CVT activities. The importance of leadership support and local champions to implementation success was also demonstrated in a recent study evaluating implementation of methicillin-resistant staphylococcus aureus (MRSA) prevention guidelines in SCI/D Centers. 28 Facilitation via internal facilitators (i.e., individuals familiar with organizational features) and external facilitators (i.e., experts in general implementation activities) is an important strategy with proven success in implementing evidence-based practices and programs. 37
Healthcare teams, including those who provide SCI/D care, are complex, adaptive systems that comprise multiple individuals interconnected with each other and their environment. 38 Integrating CVT technology into this context has unique implications for care delivery, given that CVT involves face-to-face interaction at a distance and distributes control of care processes across facilities. The processes involved in implementing CVT in SCI/D care also highlight the importance of understanding the interactions among dimensions of the sociotechnical model. 30 When CVT technology is used across healthcare facilities, it changes relationships within and between those facilities, in a sense, creating a whole new organization. The sociotechnical model underscores the implications of a new, virtual organization in which healthcare is practiced.
Specific attributes of CVT technology emphasize different dimensions of the sociotechnical model. Typically, the hardware and software computing infrastructure dimension of the model encompasses technical aspects, but the nature of CVT requires consideration of other infrastructural factors that impact the technology's implementation—namely, space. Although space itself is not necessarily a technical issue, it is difficult to conduct appointments over CVT technology without sufficient space that offers privacy and room to host a clinical care team and an individual with SCI/D. Because CVT supports people interacting remotely, the sociotechnical model dimensions centered on people, workflow, and communication were particularly relevant to our analysis. The real-time video stream supported by CVT allows for continuous interaction among people as opposed to static data sharing. Moreover, CVT benefits from the engagement of additional staff with specific knowledge, including system users (e.g., physicians) and those who support users (e.g., IT). Formal, tailored training provided by SCI/D leadership has been acknowledged as an important facilitator for implementation. 28 In the case of CVT, training is important for use of technology, and to bring the new organization together to establish rapport. When providers are unfamiliar or have not worked previously with remote counterparts, trust issues may arise. Meeting face-to-face in-person or over CVT before coordinating patient care may help in developing relationships and trust. Research has shown that the integration of virtual care modalities into the care of complex patient populations is facilitated when relationships among team members are established or recognized as important to develop. 39,40
Limitations and Future Research
A strength of this study is the inclusion of multiple facilities from the largest integrated healthcare system in the United States that cares for individuals with SCI/D. However, our findings are based on self-reports of provider experiences and perceptions. As evidenced by our data, veterans with SCI/D face unique challenges in accessing care and CVT has considerable potential to improve access for this population. By thoughtfully integrating this technology with the workflow of providers and the care experiences of patients, improvements in access may be realized and use of CVT can be sustained. Future research should focus on how best to help providers and patients understand the potential value of CVT to their practice and care.
Conclusions
We build on previous research that shows how sociotechnical models can be used to understand the sociotechnical aspects of implementation of virtual technology and the complex interactions of technology within a healthcare system. 41 Using the eight-dimensional sociotechnical model as a lens magnifies the key issues inherent in CVT implementation in SCI/D. The extent to which our data represent the model dimensions demonstrates the many social and technical factors relevant in this context. Implementation of CVT requires teams of people working together to negotiate a complex, distributed process across multiple sites. Such complexity places a premium on coordination and communication among stakeholders and may have various implications for providers as roles may change or be redefined. As CVT implementation continues to grow in the SCI/D community, efforts are needed to evaluate the application of CVT for SCI/D care. 42
