Introduction
Offering healthcare in distant or rural areas is difficult, significantly specialised drugs and surgical procedures. Sufferers could must journey lengthy distances simply to get to medical services and to speak with caregivers. They could not arrive in time to obtain important info earlier than their medical appointments and should should return house earlier than they’ll obtain essential follow-up care on the hospital. Some sufferers could wait a number of days simply to satisfy with their surgeon. It is a very totally different expertise from that of city or suburban residents or folks in additional developed areas, the place sufferers can get to a close-by clinic or hospital with relative ease.
Lately, telemedicine has emerged as a possible resolution for underserved distant populations. The COVID-19 pandemic, which prevented many caregivers and sufferers from assembly in individual, helped popularize digital medical appointments. But 2D telemedicine (2DTM) fails to completely replicate the expertise of a face-to-face session.
To enhance the standard of digital care, researchers from Microsoft labored with exterior companions in Scotland to conduct the primary validated scientific use of a novel, real-time 360-degree 3D telemedicine system (3DTM). This work produced three research starting in 2020, by which 3DTM primarily based on Microsoft’s HoloportationTM communication expertise outperformed a 2DTM equal. Constructing on the success of this analysis, the collaborators carried out a follow-up trial in 2022 with companions in Ghana, the place they demonstrated the primary intercontinental use of 3DTM. This analysis offers important progress towards rising entry to specialised healthcare for rural and underserved communities.
3DTM beats 2DTM in Scotland trials
The dramatic enlargement of digital drugs helped fill a void created by COVID restrictions, but it surely additionally underscored the necessity for extra reasonable distant consultations. Whereas 2DTM can lengthen the attain of specialised drugs, it fails to supply medical doctors and surgeons with the same amount and high quality of data they get from an in-person session. Earlier analysis efforts had theorized that 3DTM might increase the bar, however the benefits have been purely speculative. Till now, real-time 3DTM had been proposed inside a analysis setting solely, due to constraints on complexity, bandwidth, and expertise.
In December 2019, researchers from Microsoft started discussing the event of a 3DTM system leveraging Microsoft Holoportation™ communication expertise with collaborators from the Canniesburn Plastic Surgical procedure Unit in Glasgow, Scotland, and Korle Bu Instructing Hospital (KBTH) in Accra, Ghana.
With the emergence of COVID-19 in early 2020, this effort accelerated as a part of Microsoft Analysis’s COVID response, with the popularity that it might enable sufferers, together with these with weakened immune methods, to go to a specialist remotely from the relative security of a neighborhood doctor’s workplace, somewhat than having to journey to the specialist at a hospital with all of the concurrent threat of an infection.
The preliminary analysis included a deployment in Scotland, with 10 specialised cameras capturing affected person pictures, combining them right into a 3D mannequin, and transmitting the 3D picture to a medical skilled. The affected person might view the identical pictures as their physician, which allowed them to debate them in actual time—nearly as in the event that they have been in the identical room.

This work produced three separate research: a clinician suggestions examine (23 clinicians, November–December 2020), a affected person suggestions examine (26 sufferers, July–October 2021), and a examine specializing in security and reliability (40 sufferers, October 2021–March 2022).
Participatory testing demonstrated improved affected person metrics with 3DTM versus 2DTM. Though sufferers nonetheless desire face-to-face visits, 3DTM was rated considerably increased than 2DTM. Total affected person satisfaction elevated to 88 p.c with 3DTM from 51 p.c with 2DTM; realism, or “presence,” rated increased at 80 p.c for 3DTM versus 53 p.c for 2DTM; and high quality as measured by a Telehealth Usability Questionnaire got here in at 85 p.c for 3DTM in contrast with 77 p.c for 2DTM. Security and scientific concordance of 3DTM with a face-to-face session have been 95 p.c – equal to or exceeding estimates for 2DTM.

One of many final objectives of telemedicine is to carry the standard of distant consultations nearer to face-to-face experiences. This knowledge offers the primary proof that Microsoft’s Holoportation™ communication expertise strikes 3DTM nearer to this objective than a 2D equal.
“We confirmed that we are able to do it utilizing off-the-shelf elements, making it inexpensive. And we are able to deploy it and make it dependable sufficient in order that a physician or a scientific workforce might use it to conduct consultations,” stated Spencer Fowers, Principal Researcher at Microsoft Analysis.
Ghana examine: 3DTM brings medical doctors and sufferers nearer
After the profitable deployment in Scotland, the workforce turned its focus to Ghana. The analysis workforce visited KBTH in February 2022. That started the collaboration on the following section of the mission and the set up of the primary recognized 3D telemedicine system on the African continent.
Ghana has a inhabitants of 31 million folks however solely 16 reconstructive surgeons, 14 of whom work at KBTH. It’s one of many largest hospitals in west Africa and the nation’s predominant hospital for reconstructive surgical procedure and burn therapy. Touring to Accra might be tough for individuals who stay in rural areas of Ghana. It could require a 24-hour bus trip simply to get to the clinic. Some sufferers can’t keep lengthy sufficient to obtain follow-up care or satisfactory pre-op preparation and counseling. Many individuals in want of surgical procedure by no means obtain therapy, and people who do could obtain incomplete or sub-optimal follow-up care. They present up, have surgical procedure, and go house.
“As a physician, you usually take it as a right {that a} affected person will come again to see you if they’ve problems. These are literally very complicated operations. However too usually in Ghana, the medical doctors could by no means see the affected person once more,” stated Steven Lo, a reconstructive surgeon on the Canniesburn Plastic Surgical procedure and Burns Unit in Scotland. Lo has labored for years with KBTH and was the mission’s scientific lead in Glasgow.
The researchers labored with surgical workforce members in Scotland and Ghana to construct a conveyable system with enhanced lighting and digital camera upgrades in comparison with the unique setup deployed in Scotland. This technique would allow sufferers to satisfy in 3D with medical doctors in Scotland and in Ghana, each earlier than and after their surgical procedures, utilizing Microsoft Holoportation™ communication expertise.

The outcomes have been a number of profitable multidisciplinary workforce (MDT) engagements—each pre-operative and post-operative—supporting surgical procedures led by visiting medical doctors from Scotland at KBTH. The 3DTM system utilizing Microsoft Holoportation™ communication expertise helped medical doctors talk to sufferers exactly what their surgical procedure would entail forward of time after which be sure that sufferers had entry to any mandatory follow-up procedures and post-operation remedy. The medical workforce in Glasgow used Microsoft Holoportation™ communication expertise to control and mark up 3D pictures of their sufferers. Sufferers watching from Accra might visualize the process, together with the precise places the place the surgical incisions would happen.

For a affected person who got here to KBTH to handle a continual drawback together with his jaw, this visualization gave him a a lot better understanding than he had had with earlier surgical procedures, stated Levi Ankrah, a reconstructive surgeon at KBTH who participated within the distant consultations and the surgical procedures in Ghana.
“These are fairly complicated issues to clarify. However when the affected person might truly see it for himself from the surface, that helped him really feel extra concerned together with his care and his follow-up plan,” Ankrah stated.

Conclusion
One of many final objectives of telemedicine is for the standard of distant consultations to get nearer to the expertise of face-to-face consultations. The information offered on this analysis suggests important potential in transferring nearer to the expertise of face-to-face consultations, which is especially related to specialties with a robust 3D focus, resembling reconstructive surgical procedure.
Nothing can exchange the authenticity and confidence that come from a face-to-face go to with a physician. However 3DTM reveals nice promise as a possible state-of-the-art resolution for distant telemedicine, changing present 2DTM digital visits and driving higher entry and outcomes for sufferers.
