Pre-Implementation Interviews
A total of 13 (ten female, three male) health care professionals participated in the baseline interviews prior to implementation of video consultations. Four participants were physicians, six were nurses, and three were medical technical assistants (see Table 1). Participants were asked to identify current process structures and problems. Furthermore, they were asked to name problems that might be alleviated with video consultations and to express their expectations regarding the advent of telemedicine. The interviews lasted an average of 32 minutes.

Depiction of Current Practice (Pre-Implementation)
To make a request for an acute care visit to the nursing home (1, please refer to Fig. 1 for the flowchart), the nurse contacts the primary care physician's office via telephone (2) or fax (3). The choice of contact method is at the discretion of the nurse, or following the previously established method of contact between the nursing institution and the medical practice. When contact is made by telephone, the medical assistant at the physician’s surgery takes the call (4) and records the request in writing for transmission to the doctor (5). The physician reviews the request and contacts the nursing facility by phone to discuss the issue (6). In some cases, the medical technical assistant may put the call through directly to the physician (7), such that the physician and the nurse can discuss directly the issue (8). The medical technical assistant decides upon direct or indirect communication based on the current workload in the practice.
In the case of fax communication from the nursing home, the medical technical assistant receives the fax and transmits it to the physician (9). In this step, the physician checks the request (10) and then contacts the care facility by telephone (11). When subsequently contacting the nursing home, the following scenarios of care are possible: the physician recommends that the ambulance service be contacted for hospital transfer (12), the physician prescribes or adjusts a medication, or (13), schedules a nursing home visit by the physician (14) or by a medical technical assistant (e.g., for blood sampling or wound documentation) (15).
Problems in the current process
When describing the process for requesting external medical support, the interviewees were asked to name the current obstacles that they perceived in the delivery of care. It emerged that when nurses contact the medical practice by phone, they often had to make several calls to reach the medical technical assistants:
„Some just answer the phone, some only have certain times when they answer the phone, and then the pressure is rising [...]. So I try to do it on the side, because I can't sit in front [of the phone] the whole time and try again in ten minutes, because then the time for the care runs out again.” (MUT_101, Pos. 88)
In cases calling for a regular physician home visit, participants frequently noted that nurses would have to interrupt on short notice their daily care routine to be able to participate in the visit.
„He [the doctor] comes at peak times, when it's lunchtime and you're the only nurse in the living area. I'm either supposed to hand out the medicine or accompany the doctor. I'm a bit grumpy when I have to run away. People need their midday medicine; they're waiting at the lunch table. Then he [the doctor] hangs around for ten minutes, waiting again for you to come.“ (MUT_113, Pos. 20)
When contacted via fax, while faxes arrived directly at the practice, they are not always promptly transmitted to the physician, resulting in delays in arranging an appointment for face-to-face consultation.
„For example, if the resident has 39.4 fever and somehow it is not possible to see what he/she had. [...]. I called the general practitioner and was told that we should send [the inquiry as] a fax. Then, of course, I get angry. I need an answer NOW and not in the afternoon, when the fever has risen even higher, so I would need someone to give me some information and I can't send a resident to the hospital because of such a temperature. “ (MUT_107, Pos. 6)
In this context, the medical technical assistants have a mediating function. This may not only lead to delays before a consultation can be initiated, but may also result in the loss of information relating to patients and their care.
„The problem is that a written request always comes in by fax and then we fax it back again […]. That means it is always done by fax, because it is [even more] difficult by phone. This happens during our practice hours, when the MTA [medical technical assistant] can't say much about it, the time is short and that is really a big problem. That's when information gets lost.“ (MUT_106, Pos. 18)
If contact is made by fax, the physician must contact the nursing home again by telephone to arrange an appointment, which requires additional effort on the part of the physician.
„Yes, for example, everything is currently processed via fax communication. So, when the nursing home makes an inquiry, it is usually made by fax. I usually like to make a phone call, because everything is too vague for me and I want to have it explained. And then I have to answer again by fax. So even though I usually discuss it in advance, I still have to make another written order, for example, so that the colleagues there, the geriatric nurses, have a written order and can work more [assurance] for themselves, and of course that process always duplicates itself somehow.“ (MUT_110, Pos. 8)
In addition, the time expended in visiting the nursing institution, which leads to additional work for the physicians, was also identified as a source of inefficiency. Stakeholders on both sides described that there are often delays in treating nursing home residents because of the often very protracted process to initiate counseling.
„From the moment when we send out a fax, it actually takes a day before we even get a response.“ (MUT_112, Pos. 26)
The physicians, on the other hand, mentioned that they first have to locate the responsible nursing staff on the unit, which frequently wastes a lot of their time.
„When I went to the nursing home and had my faxes in hand, [indicating] to whom I had to go, I always went to the ground floor living area and said, "I have this one [patient] and that one [patient], I don't have this and the other one [patient]”. And then I always have to run to the next living area and first of all look for the nursing staff. That is always difficult.“ (MUT_104, Pos. 20)

Sample post-implementation interviews
Eight people (six female, two male) took part in the post-implementation interviews; there were three physicians, three nurses, and two medical assistants due to dropout of one physician, three nurses and one assistant (see in Table 2). The focus of the second session was the analysis of the realisation of video consultations in everyday care, and changes in the process description of the consultations after implementation of telemedicine. Other topics were the problems encountered in implementation, and perceived advantages from telemedicine and its potential for improving the care of patients in nursing homes. The interviews lasted an average of 35 minutes.

Depiction of practice after the implementation of videoconferences
Ten weeks after the implementation of videoconferences in everyday care, the stakeholders were asked to describe the revised process: The physician first makes a recommendation for a video conferencing appointment (1). The video consultations are prescheduled, not arising in response to acute issues. Next, a nurse checks if there are patients who acutely need a physician visit and transmits the patient-relevant information via the video conferencing system one day before the scheduled video consultation time slot (2). In this process, all patients are individually assigned an appointment for their respective issues. Following the video consultation (3), the physician can then initiate a medication prescription or adjustment measures (4), arrange an additional face-to-face appointment (5) or another video consultation (6) (see post-implementation flowchart in Fig. 2).
Impact on current process post implementation
Stakeholders outlined the following changes: A fixed, weekly time slot for video consultations allows scheduled visits to be made for selected patients, as well as enabling ad hoc meetings. This affords the opportunity for nurses to address acute problems without needing to contact the practice again.
„By creating this one time slot for visits, there is definitely also a certain amount of reliability, planning reliability for the nursing staff. [We are] able to address specific problems in a focused manner, and then together with the patient if necessary.” (MUT_202, Pos. 35)
The use of video consultations and direct appointment setting eliminates the medical technical assistants’ interface and patient- and care-relevant information is not likely to be lost.
„It doesn't have to go through an additional person who receives the same information and passes it on to me, and I still then have the nurses describe it to me again in person, because as I said, the loss of information had otherwise already occurred.” (MUT_202, Pos. 10)
Through the use of electronic visits, continuity of care can be increased and information on patients can be exchanged conveniently. Video consultations reduce interruptions in the day-to-day care of nurses, and physicians no longer have to search for the responsible nurses in the nursing home. If physicians visit the nursing institution spontaneously, this can sometimes lead to longer waiting times for the doctor because the nurses have to accompany them on their ward round at the cost of performing their everyday nursing work. The physicians described that the video consultation hours helped to reduce delays in the daily care routine.
„I then had first look for the nurse, and had to wait five minutes and then I'm pissed off. Because I also lacked the time. It's also time pressure. It's an extra task for me that I haven't planned for during the many home visits, and then I have an extra task and I have to wait until one of the ladies or gentlemen [nurses] comes by. Of course, this also affects my mood and puts pressure on my time with the patients. So, I have to say, "Well, come on, guys! Quickly, quickly! I have to move on!". And now I can do that [visitation] from my armchair with a cup of coffee.“ (MUT_204, Pos. 8)
In addition, travel requirements are eliminated and, if necessary, the attending physicians can care for several patients in the nursing home along with other patients in their regular practice routine during this allotted telehealth time.
“I just do not have an extra trip and thus also save time. There and back, look at the patient, document the treatment. I have a time saving of almost an hour.” (MUT_204, Pos. 16)
Through direct communication via video consultation, medical aids and appliances can be prescribed more quickly, and medications can be prescribed or adjusted.
„So, I say to Dr. W., it's much quicker than if he came here and I discussed everything with him first, and yes, he can decide more quickly who is in immediate need of a visit on site (MUT_207, Pos. 8)
The documentation in the video consultation software also reduces the organisational and administrative effort, especially for the physicians.
„Yes, the [need for] faxes is changed, but of course it is still the case that we order the medication in this way; that is normal. But the [need for] communication via faxes about present concerns of the residents, when we needed a consultation, when we needed a new treatment care order or something, that is now all settled in this one appointment. This means that there is really only a single e-mail or invitation at that moment via D. [the video consultation software], [which identifies] what the consultation is about, meaning that - let’s say - seven, eight, nine faxes no longer have to be sent out!“ (MUT_208, Pos. 6)
