The United States (US) Health Information Technology for Economic and Clinical Health Act of 2009 has spurred adoption of electronic health records. The corresponding meaningful use criteria proposed by the Centers for Medicare and Medicaid Services mandates use of computerized provider order entry (CPOE) systems. Yet, adoption in the US and other Western countries is low and descriptions of successful implementations are primarily from the inpatient setting; less frequently the ambulatory setting. We describe prescriber and staff perceptions of implementation of a CPOE system for medications (electronic- or e-prescribing system) in the ambulatory setting.
Using a cross-sectional study design, we conducted eight focus groups at three primary care sites in an independent medical group. Each site represented a unique stage of e-prescribing implementation - pre/transition/post. We used a theoretically based, semi-structured questionnaire to elicit physician (n=17) and staff (n=53) perceptions of implementation of the e-prescribing system. We conducted a thematic analysis of focus group discussions using formal qualitative analytic techniques (i.e. deductive framework and grounded theory). Two coders independently coded to theoretical saturation and resolved discrepancies through discussions.
Ten themes emerged that describe perceptions of e-prescribing implementation: 1) improved availability of clinical information resulted in prescribing efficiencies and more coordinated care; 2) improved documentation resulted in safer care; 3) efficiencies were gained by using fewer paper charts; 4) organizational support facilitated adoption; 5) transition required time; resulted in workload shift to staff; 6) hardware configurations and network stability were important in facilitating workflow; 7) e-prescribing was time-neutral or time-saving; 8) changes in patient interactions enhanced patient care but required education; 9) pharmacy communications were enhanced but required education; 10) positive attitudes facilitated adoption.
Prescribers and staff worked through the transition to successfully adopt e-prescribing, and noted the benefits. Overall impressions were favorable. No one wished to return to paper-based prescribing.
For years, the Institute of Medicine has championed the use of electronic health records (EHRs) as a way to improve the quality, safety, and efficiency of the United States (US) healthcare system. [1–7] Yet data from a national survey conducted in 2007-2008 revealed that only 4% of physicians practicing in the ambulatory setting reported using a fully functional EHR.  The Health Information Technology for Economic and Clinical Health Act has since provided needed impetus to spur adoption. The Office of the National Coordinator for Health information Technology (HIT) has set initial standards, specifications, and certification criteria for EHRs.  The Centers for Medicare and Medicaid Services has defined what constitutes 'meaningful use'. 
Topping the proposed meaningful use list, and necessary for certification, is the computerized provider order entry (CPOE) system to order medications, laboratory tests, procedures, images, and referrals.  Yet, a recent review of CPOE implementation in hospitals in seven Western countries (Australia, France, Germany, the Netherlands, Switzerland, United Kingdom, and US) reveals that implementation is slow, with adoption rates of 20% or less.  Integration to existing EHRs is problematic; indeed, in these countries, the use of EHRs is also rare. [11, 12] These investigators found no relationship between health care system organization and CPOE implementation, noting that the cost burden of implementation often rests with the hospitals, despite the existence of national or regional incentives for adoption. Issues of professional autonomy, identity and conflict remain as barriers. In this environment, examples of successful CPOE adoption are critically important. To date, most examples are from academic medical centers, using homegrown systems; fewer reports are from the ambulatory setting. [13–18] The work of one team of researchers - the physician order entry team (POET) - describes a successful implementation in the ambulatory setting of a health maintenance organization (HMO). [19–21] To our knowledge, a detailed description of the perceptions of physicians that have successfully implemented a CPOE system in an independent medical group practice has not been published.
We implemented CPOE software for medication ordering - an electronic (e-) prescribing system - in an independent medical group. Clinic leadership motivated the implementation by highlighting the expected improvements in medication safety and efficiencies associated with use of fewer paper charts. We have published a collection of studies that describes the impact of this implementation on medication errors and adverse drug events , on the attitudes of prescribers and staff toward e-prescribing adoption , and on the time-intensity of e-prescribing . We have also narrated the lessons we learned that enabled successful adoption . In this companion manuscript we describe the results of a series of focus groups we conducted with physicians and staff across three primary care sites in varying stages of e-prescribing implementation. Our primary objective was to describe their perceptions, to note what worked well, what needed improvement, and what contributed to successful implementation. Our secondary objective was to map our findings to a theoretical model that describes information technology (IT) adoption - the Information Technology Adoption Model (ITAM). [26–28]
Dixon used the ITAM to study IT adoption in the primary care setting. [28–30] We use it to provide the theoretical underpinning for elicitation of end user perceptions of an e-prescribing system. Our end users are the prescribers and staff. We enhance the model in proposing that, as leadership receives feedback from end users, system improvements are made, end users' perceptions modified, and adoption increased. Our enhancement is the link between adoption and IT Requirements, which we represent with a bold, dotted arrow. We represent the continuous improvement loop with bold arrows.
We conducted the study at The Everett Clinic, the largest independent medical group in Washington State. Physician-owners care for 275,000 patients in sixty clinics, at fourteen sites within a twenty-mile radius in the north Puget Sound area. The Everett Clinic logs 650,000 ambulatory visits and clinicians write 2.7 million prescriptions annually. HIT staff began development of a homegrown EHR in 1995. Early on, the EHR was comprised of electronic chart notes, laboratory values, and imaging reports. The e-prescribing module was rolled out from 2003-2005 and interfaces with the existing EHR. The e-prescribing system is web-based and uses point-and-click functionality. The system makes use of the drug database from Multum™ (Cerner, Denver, CO). It generates new and renewed prescriptions. Prescribers select medications from pull-down menus or from 'favorites' lists. Directions can be selected or typed as free-text. During the study the e-prescribing system included only basic dosing guidance; duplicate therapy checks; and, when the clinician enters a child's weight, weight-based, pediatric dosing of drug, strength, and bottle size (if liquid medication). Allergy, drug-drug interaction, drug-disease interaction, and laboratory monitoring alerts were added after completion of data collection. Clinic staff (nurses and medical assistants) enter prescriptions into a queue for review; only licensed prescribers can authorize and release these to a pharmacy of the patient's choice.
E-prescribing implementation was initiated first at primary care clinic sites where providers were eager to embrace the technology, the rationale being that early successes would set a positive example for those reluctant to adopt. Use was initially voluntary. Implementation in specialty clinics took place subsequent to study completion. Clinic-wide use was eventually mandated. Initially, physicians accessed the EHR via desktop PCs in their personal offices or at shared workstations; staff accessed solely from workstations. Shortly after e-prescribing rollout, The Everett Clinic made the strategic decision to enhance EHR access by installing a PC in each of 505 examination rooms. A portable laptop was provided to each physician as an interim step toward this end.

Fourth Topic Area:
Facilitators and barriers to e-prescribing implementation
Primarily for Float Pool Focus Group Participants
"What do you see as the facilitators and barriers to e-prescribing implementation?"
At the launch meeting, we explained the study and invited all physicians and staff to participate. Participants could then attend the focus group scheduled at their site, specific to professional role. Meetings were held at breakfast or lunchtime to facilitate participation. Three to eight participants attended each group, with the exception of the float pool group, which was attended by 22 staff. Each focus group lasted thirty minutes. At each focus group, an oral consent script was read; consent was granted by those remaining in the room (all remained). One clinician-investigator (EBD or THP) facilitated each focus group. The same research assistant (KLT) attended all focus groups, and typed anonymized discussions directly into a laptop. In total, 70 participants attended; 17 physicians and 53 staff. Between 38% (site A) and 80% (site C) of physicians participated; between 36% (site A) and 48% (site C) of staff participated. (Table 1)
We employed formal qualitative methods for analysis. Two coders separately coded a total of 26 pages of transcripts. One coder (EBD) was familiar with the existing literature and had led both the a priori mapping exercise and the development of the Focus Group Questionnaire. She was also familiar with initiatives at The Everett Clinic. When coding, she employed both deductive and phenomenologic epistemologic frameworks.  The other coder (ECW) was less familiar with the existing literature, and had no knowledge of The Everett Clinic. She used grounded theory techniques.  Each used micro-analytic techniques and axial coding to create code families, then themes.  Each coded to the point of theoretical saturation, that is, until no new themes emerged. Differences were resolved through discussions. We identified 142 codes and collapsed these into themes. All analyses were completed using Atlas.ti® version 5.5.9 (Berlin, Germany). Our report follows the consolidated criteria for reporting qualitative research (COREQ). 
Ten themes emerged. Each theme describes participants' perceptions about e-prescribing implementation. We combined results from prescribers and staff within each theme, as all types of professionals were inextricably linked in the order entry process.
Theme 1: Improved availability of clinical information resulted in prescribing efficiencies and more coordinated care
Participants noted prescribing efficiencies and more coordinated care from the improved availability of patient-specific information. Physicians anticipated forthcoming implementation of more sophisticated, patient-specific CDS alerts to guide ordering. At the same time, aware of alert fatigue, physicians expressed a desire for CDS alerts to be relevant.
"...more information about the refill request. It tells you the last visit, last lab, last refill - you don't have to take time to figure that out and it's extremely helpful." -Physician
"Drug interactions, when you add them, will be very helpful, but we do not want to be inundated with information that is mundane, such as, 'don't take with coffee'". -Physician
Staff perceived the ability to view all prescriptions as a benefit. Staff perceived this enabled them to better track controlled substances, prevent patients from requesting untimely refills, or refills from more than one prescriber concurrently.
"...to be able to get a history of prescriptions - that's incredible". - Staff
"...can track controlled substances in urgent care better." - Staff
Theme 2: Improved documentation resulted in safer care
Participants expected the e-prescribing system to reduce medication errors and improve accuracy. At the same time, physicians perceived they needed to be cautious when prescribing, so as not to introduce computer-generated errors.
"It has turned out to do what it was billed to do - reduce/decrease errors." - Physician
"Yes, I learned that I had to be very careful if I was dictating on one patient and switched to another patient. I had to be very careful that I had the right person." - Physician
Staff perceived a diminished ability for patients to modify prescriptions, as these were sent directly to the dispensing pharmacy via the fax server.
"...eliminates the problem like when the doctor writes a prescription for 10 Vicodins™, and the prescription is changed to 100 Vicodins™." - Staff
Theme 3: Efficiencies were gained by using fewer paper charts
Physicians perceived that moving from paper to e-prescribing made the prescribing process easier and quicker.
"it is much faster than waiting for the dictation to be processed." -Physician
Staff expressed doubts about ever eliminating paper charts, but perceived the benefit of fewer chart pulls and the associated time-savings.
"...there are definitely fewer chart pulls to garner information, and that saves a lot of time and money. Even receptionists can look at information and tell patients about prescriptions." -Staff
Theme 4: Organizational support facilitated adoption
Participants perceived the importance of organizational support. Physicians appreciated the availability of technical support and requested follow-up training. They felt empowered to request improvements. One physician stated that the responsiveness of the implementation team facilitated adoption. Physicians appreciated that using the system was initially voluntary.
"The clinic as an organization provides support to you. You can also call the Help Desk or the clinical pharmacist." -Physician
"There are no mandates or ultimatums about using the computer system." -Physician
In contrast, staff wished all were required to use the system at the outset, and expressed a fear of 'hold-out' physicians.
"Not using the system is s downfall - everyone should have to use it." -Staff
Theme 5: Transition required time; resulted in workload shift to staff
Participants acknowledged the transition would take time. They noted that entering existing prescriptions into the system was an important transition step, and perceived that efficiencies would eventually be realized.
"...learning curve - it will take time to get it going." -Physician
The burden of transition fell largely to staff, as they took responsibility for entering existing prescriptions. In essence, a workload shift occurred. Staff became facilitators of adoption, by adopting first and then assisting physicians. Physicians acknowledged the important role of staff and were appreciative of the help.
"It's a matter of getting staff to be willing to accept it and they get the providers to work with it. In a slight way, the workload is deferred from prescribers...now we're loading prescriptions into the system." -Staff
"...the medical assistants gradually got the current medications entered. If the providers had had to enter the prescriptions, it would have never happened." -Physician
Theme 6: Hardware configurations, network stability were important in facilitating workflow
Two aspects of hardware configuration were perceived as instrumental to successful implementation - remote access from home for physicians and the availability of a personal laptop computer in each examination room. Physicians stated that remote access made access to clinical information easier, enabling them to provide better and more coordinated care. Simultaneously, they expressed concern about system security. Physicians also perceived the benefit of having the laptop computer in the examination room.
"I also like it for nighttime calls - you can see what medications the patient is on. It really helps with patient care. - Physician
"Having a record in the exam room has been a tremendous help." -Physician
Participants also perceived that they had become reliant on network stability. Staff noted the workarounds required when the system 'went down'.
"When/if the computers go down. This is when you realize that you've really adapted." -Physician
"It is more difficult when the system goes down. You have to come up with other ways to determine what the patient has been prescribed..." -Staff
Theme 7: System use was time-neutral or time-saving
Physicians did not expect time-savings; they expected that using the system would initially take longer, especially when caring for patients with multiple, complex problems. Many were pleasantly surprised, noting that refills were quicker and easier to process. Some even noted that it shortened their day in the office.
"This has been helpful to me. I don't know that it saves me any time, but it helps." -Physician
"We were told it would help with refills - they would be easier and they have been." -Physician
"It shortens your day in clinic by allowing you to work from home." -Physician
Staff perceived the system saved time after the transition period.
"...definitely a lot of work in the beginning, but now that we're on the one-year mark, wow, it's much faster!" -Staff
Theme 8: Changes in patient interactions enhanced patient care but required education
The effect of the e-prescribing system on patients figured prominently in discussions. Although initially, physicians feared that they would lose the eye contact usually made when handing a paper prescription to a patient, they noted this fear was not realized. They noted the e-prescribing system facilitated improved scheduling.
"...don't feel like there has been a negative interaction. I think the patients are happy." -Physician
"We like being able to see patients when they want to be seen, and also, reducing backlog." -Physician
Staff were pleased with the ease with which prescriptions could be refilled, and with which they could identify patients in need of follow-up. Staff noted the need for patient education, as they perceived that patients sometimes failed to realize their prescriptions were sent to the pharmacy ahead of them, and this created confusion.
"...expected to make it easier to do refills for patients. It has done that. We are able to catch patients who haven't been in for a long time...tell them they need to come in...." -Staff
"...patients don't understand how we're getting the prescription to their pharmacy, so patients end up waiting here for a prescription that has already been computer-faxed to their pharmacy." - Staff
Theme 9: Pharmacy communication was enhanced but required pharmacy and patient education
Physicians were mostly silent on this theme, as communicating with pharmacies was a role that fell largely to staff. Staff initially noted that computer-faxing eliminated pharmacy-related telephone calls but later realized that educating pharmacists about the new system was necessary to smooth the prescription ordering process. Staff also noted that patients required education about the time needed for pharmacies to fill each prescription.
"I like not having to be on hold on the telephone with the pharmacist a lot." -Staff
"Some fax machines will only try to send a fax so many times...if the pharmacy line is busy, how will we know this?" -Staff
"A pharmacist says there are times...prescriptions can really stack up and when a patient gets there, it has not been filled. There needs to be patient education about giving the pharmacy time...just because it is electronic, doesn't mean it is instantaneously filled." - Staff
Theme 10: Positive attitudes facilitated adoption
Participants' attitudes contributed to successful adoption. Many came into the project with a 'can-do' attitude. Others were more reserved, yet determined to adopt; confident that it would eventually be beneficial.
"We are expecting the change to come and that the bugs will get worked out." -Physician
"Once I got used to it, it was OK. I'm not the fastest person with new technologies, but we got the basics..." -Physician
Those who had a solid background in computer use expressed confidence in their abilities and found it easy to use.
"I used the system from the very beginning... The system I used before was different - this one is better. I've used e-prescribing since I graduated from medical school." -Physician
The strategy of implementing last at the site where the most reluctant physicians practiced seemed to help.
"...now that providers at other sites have done it, we can probably do it, too." -Physician
Overall, impressions were positive. Physicians expected the system to be useful, and had no concerns about it having a negative impact. When asked if they would recommend the system to their former medical school classmates, one physician responded,
"Yes, absolutely, I'd participate in using this system". -Physician
"We are not expecting things to be negatively impacted." - Physician
Staff expected the e-prescribing system to offer accuracy and convenience.
"Faster, more convenient, more accurate" -Staff
"It's been easier than expected." -Staff
"Do it! Absolutely! It's a good thing." -Staff
Mapping Focus Group Results to the ITAM
Our findings describe perceptions of physicians and staff when adopting a homegrown, EHR-based, e-prescribing system in primary care clinics in an independent, medical group. Our findings mapped logically to the ITAM where themes fit the categories of benefits and drawbacks to both perceived usefulness and perceived ease of use of the e-prescribing system, albeit with some potential overlap. As intended by leadership when specifying IT requirements, the e-prescribing system was perceived to be useful in creating prescribing efficiencies, more coordinated care, and safer care from improved availability and documentation of clinical information. Another initial motivator, the decreased administrative burden of paper charts, was also perceived to hold true. Another efficiency, the time-savings achieved in ordering refills, was also perceived to be useful. Not highly anticipated were the educational initiatives undertaken that were motivated by the changed way patients interacted with physicians and staff interacted with pharmacies. Both were perceived as useful and beneficial.
Contributing to perceived ease of use was support from organizational leadership, the availability of technical support and participant empowerment to request improvements. Interestingly, physicians thought voluntary use eased the transition, while staff thought the opposite. This reflects the burden staff felt during the transition, when entering prescriptions into the system. Importantly, staff shouldering the burden contributed to ease of use by physicians and, ultimately, to successful adoption. Two major factors contributed to ease of use and resulted in permanent changes in workflow: physicians having remote access from home and having a laptop computer (and perhaps eventually a PC) in each examination room. Both were perceived as beneficial. Finally, the positive attitude of all participants contributed to ease of use. Positive attitudes could also be thought of as personal characteristics that each user brought to bear to achieve adoption.
Challenges were also noted from both perspectives of perceived usefulness and perceived ease of use. Prescribers' awareness of the well-known issue of 'alert fatigue' predated implementation of CDS alerts. Participants were aware of computer-generated errors, but these were perceived to occur infrequently. Staff did not expect patients and pharmacies would require education to successfully interact with the changes brought on by the system. Ongoing training and support were necessary to ensure continued ease of use, as was network reliability. The two greatest drawbacks were the time required for the transition, and the burden that inputting prescriptions placed on staff. These findings reveal the importance of setting realistic expectations and timeframes for transitions to full adoption. The Everett Clinic did anticipate this; physician and staff schedules were adjusted to be less demanding during the first three months of the transition. Even so, the lesson was markedly demonstrated. Although attitudes of participants ranged from reluctant to enthusiastic, an optimistic attitude prevailed. Participants were determined to realize the benefits of the system. The strategy of implementing last at the reluctant site (Site C) paid off, as the reluctance of those at site C was overcome through the examples set by those at sites A and B. That the system held more benefits than drawbacks was clear from the majority of focus group participants. None mentioned wanting to return to the paper-based system. The focus group results proved useful in implementing the e-prescribing system in specialty clinics.
Our focus group study is the fourth in a collection of four studies we conducted during e-prescribing implementation at The Everett Clinic. Our focus group findings are largely consistent with the results of our other work. [22–25] The mention of improved medication safety, triangulates well with the findings from our first study wherein we estimated a 70% reduction (95% confidence interval (CI) 0.23, 0.40) in the adjusted odds of a medication error occurring with e-prescribing when compared to paper-based prescribing. The positive attitudes of focus group participants triangulate well with the results of our second study, wherein we administered a survey instrument - Information Technology in Primary Care Practice - to many of these same focus group participants.  The instrument was developed from the ITAM. [26–28] Domain score results revealed that intent to adopt increased significantly for both prescribers (p < 0.04) and staff (p < 0.03) at Site C between pre- and post- implementation, and perceived usefulness increased for staff (p < 0.02). The time required to e-prescribe is not heralded by participants in the focus group study. In contrast, the results from our third study revealed that the average time to e-prescribe in the examination room was 69 seconds per prescription - 25 seconds longer than to handwrite (99.5% CI 12, 38), and 24 seconds longer than to e-prescribe at offices/workstations (99.5% CI 8, 39).  Each calculates to 20 seconds longer per patient or approximately six minutes per prescriber, per day. There are three reasons why there are disparate results between these two studies. First, at the time of the focus group study the time increase had not yet been quantified, as the time-motion study was completed subsequent to the focus group study. Second, the benefits of increased availability of clinical information and improved safety perceived by focus group participants may have mitigated physicians' concerns about time spent e-prescribing, to the point that these were expressed as being time-neutral. Third, at Site A, focus group results reflect the use of a personal laptop carried by each physician into the examination room with him/her, rather than use of a PC computer that was eventually installed and hardwired in each examination room. What is noteworthy is that focus group results reveal that physicians were enthusiastic about using a computer in the examination room, despite the impact on workflow. We describe this impact in greater detail in our narrative of lessons learned from implementation.  We also narrate other aspects of successful implementation: leadership motivates implementation, an iterative roll-out, sufficient organizational and technical support, adequate communication with all stakeholders, a team-oriented culture, readily accessible training, ongoing involvement of clinicians and integrating workflow redesign into implementation.  Much of this narration is echoed by focus group participants.
Our findings are consistent with those of others. Barriers to full adoption are many and include immature CDS tools, limited connectivity with dispensing pharmacies, and the time-intensity of rollout.  The issue of alert fatigue has been well-described. [46, 52–54] Computer generated errors are a constant concern.  The issue of the impact of CPOE, indeed of HIT initiatives in general, on workflow is increasingly being recognized as critically important. [18, 55–57] The work of Niazkhani  and Aarts  suggest that CPOE implementation is complex and that it has a profound impact on collaborative workflow beyond that of the provider. Papers that explore the interaction between IT and work processes featured prominently at the Third International Conference on Information Technology in Health Care: Socio-technical Approaches, recently held in Sydney, Australia. 
In a large Australian teaching hospital Georgiou identified nine areas of shared concern including work practices, software/hardware, relationships/communication, education and training, inexperienced staff and de-skilling (inability to function without the system).  The multi-method work of the POET investigators, also conducted in the inpatient setting, identified four high-level themes that summarize perceptions of CPOE systems: 1) organizational issues, 2) clinical/professional issues surrounding customization, 3) technical/implementation issues, and 4) issues of the organization of information and knowledge.  They learned that a culture of collaboration and trust, and one that engages clinicians in the process is critical to successful implementation. In the ambulatory HMO setting, they identified the additional concepts of increased patient involvement, information integration across sites, having a computer in each examination room, security concerns, and the centrality of the CPOE system to work life. They noted that gradual rollout, careful project management and ongoing improvements are critical to success. [19, 20] Despite the challenges, a recent survey of US physicians using commercially-based CPOE systems revealed that they believe these systems can improve safety, quality, and efficiency, and most do not wish to return to paper-based systems.  Because our findings are consistent with others, we posit that our findings may be of interest to other ambulatory medical groups faced with the challenges of implanting a CPOE system in the context of an EHR.
There are limitations to our work. Although all physicians and staff were invited to participate, some chose not to. The resulting discussions may have been biased in favor of or against the system. Importantly, our work is cross-sectional. Yet, our data reveal that participants at Site C who were initially reluctant, were successfully transitioning, suggesting that they would ultimately adopt the e-prescribing technology. Despite these limitations, our data are rich in the variety of implementation stages and health care professionals represented. The unique perspectives of our two coders maximized our ability to identify all relevant themes.
E-prescribing/CPOE systems have potential to improve the safety and quality of patient care. Our focus group work brings the perspective of participants from an independent medical group, and suggests that e-prescribing adoption can be successful in this setting. The approach taken by our group, including communicating initial motivators, staged rollout, providing ongoing support, and empowering participants to provide feedback facilitated successful implementation. Physicians and staff worked together during the transition phase, and described the benefits of efficiency, safety and improved patient care. Important to the ambulatory setting were patient interactions, pharmacy communications, remote access, and having computers in examination rooms. Collectively, participants embraced the change, were favorably impressed with the results, and did not wish to return to the world of paper-based prescribing.
