ecognizing that patients prioritize convenient
and inexpensive care, Duffy and Lee recently
asked whether in-person visits should be-
come the second, third, or even last option for
meeting patient needs.1
Previous
work has specifically described the
potential for using telemedicine
in disasters and public health
emergencies.2
No telemedicine
program can be created over-
night, but U.S. health systems
that have already implemented
telemedical innovations can lev-
erage them for the response to
Covid-19.
A central strategy for health
care surge control is “forward
triage” — the sorting of patients
before they arrive in the emergen-
cy department (ED). Direct-to-con-
sumer (or on-demand) telemedi-
cine, a 21st-century approach to
forward triage that allows pa-
tients to be efficiently screened,
is both patient-centered and con-
ducive to self-quarantine, and it
protects patients, clinicians, and
the community from exposure. It
can allow physicians and patients
to communicate 24/7, using smart-
phones or webcam-enabled com-
puters. Respiratory symptoms —
which may be early signs of
Covid-19 — are among the con-
ditions most commonly evaluated
with this approach. Health care
providers can easily obtain de-
tailed travel and exposure histo-
ries. Automated screening algo-
rithms can be built into the intake
process, and local epidemiologic
information can be used to stan-
dardize screening and practice
patterns across providers.
More than 50 U.S. health sys-
tems already have such programs.
Jefferson Health, Mount Sinai,
Kaiser Permanente, Cleveland
Clinic, and Providence, for ex-
ample, all leverage telehealth tech-
nology to allow clinicians to see
patients who are at home. Systems
lacking such programs can out-
source similar services to physi-
cians and support staff provided
by Teladoc Health or American
Well. At present, the major barrier
to large-scale telemedical screen-
ing for SARS-CoV-2, the novel co-
ronavirus causing Covid-19, is
coordination of testing. As the
availability of testing sites ex-
pands, local systems that can test
appropriate patients while mini-
mizing exposure — using dedi-
cated office space, tents, or in-car
testing — will need to be devel-
oped and integrated into telemed-
icine workflows.
Rather than expect all outpa-
tient practices to keep up with rap-
idly evolving recommendations re-
garding Covid-19, health systems
have developed automated logic
flows (bots) that refer moderate-
to-high-risk patients to nurse tri-
age lines but are also permitting
patients to schedule video visits
with established or on-demand
providers, to avoid travel to in-per-
son care sites. Jefferson Health’s
telemedical systems have been suc-

cessfully deployed to evaluate and
treat patients without referring
them to in-person care. When test-
ing is needed, this approach re-
quires centralized coordination
with practice personnel as well as
federal and local testing agencies.
It is critical that practices not rou-
tinely refer patients to EDs, urgent
care centers, or offices, which
risks exposure of other patients
and health care providers.
Patients presenting for in-per-
son care who screen positive for
high-risk features should be iso-
lated immediately to avert further
contact with patients and health
care workers. Before the Covid-19
outbreak, many EDs modified the
“provider-in-triage model” (rapid
initial evaluation and testing) by
allowing a remote provider to
perform intake.3
Aurora Health,
for example, partnered with a
commercial telemedicine vendor,
and others have developed their
own software for this purpose.
In an emergency situation, web-
conferencing software with a se-
cure open line from a triage room
to a clinician can be implemented
relatively rapidly. Covering multi-
ple sites with a single remote cli-
nician can address some work-
force challenges, but it is difficult
to do if your software lacks a
queuing function.
Tablet computers can be
cleaned between patients using
well-defined infection-control pro-
cedures. In ambulatory care set-
tings, patients screening positive
at presentation can be given a tab-
let and isolated in an exam room.
A telehealth visit can be conducted
without exposing staff by using
commercial systems or paired tab-
lets allowing communication with
a clinician through a dedicated
connection. Because of supply-
chain challenges, we rapidly re-
purposed and deployed tablets
we already had. We expect that
Covid-19 testing will be more
widely available shortly, but initial-
ly patients who were well enough
to be sent home were quarantined
there while home-based testing
was coordinated. This system
works for patients who are well but
cannot totally eliminate health
care workers’ exposure to sick
patients who require procedures.
Similar televisit systems are also
being used for hospitalized pa-
tients to reduce exposure risks for
visitors and staff.
Electronic intensive care unit
(e-ICU) monitoring programs,
which allow nurses and physi-
cians to remotely monitor the sta-
tus of 60 to 100 patients in ICUs
in multiple hospitals — such as
services offered by Mercy Virtual
Care Center, Sutter Health, and
Sentara Healthcare — are ideal
for monitoring sicker patients.
Technological and staffing com-
plexities make it impossible to
create such a program on short
notice, but rapid deployment of
the two-tablet approach can re-
duce health care workers’ contact
with infected patients in the ICU.
Community paramedicine or
mobile integrated health care pro-
grams allow patients to be treated
in their homes, with higher-level
medical support provided virtu-
ally. Houston’s Project ETHAN
(Emergency Telehealth and Navi-
gation) has used telemedical over-
sight by physicians to augment
care offered in person by 911 re-
sponders, reducing the need for
transportation to the ED.4
In the
face of Covid-19, Avera Health is
preparing to send mobile home
health care units directly to pa-
tients and is coordinating home-
based testing. For sicker patients
at home, such programs can fa-
cilitate evaluation before hospital
transfer, potentially allowing them
to bypass the ED and be placed
directly in a hospital bed, reducing
exposure for health care workers
and other patients.
Much medical decision making
is cognitive, and telemedicine can
provide rapid access to subspecial-
ists who aren’t immediately avail-
able in person. This approach has
been explored most fully in the
context of stroke, for which sys-
tems such as Jefferson Health,
Cleveland Clinic, and the Univer-
sity of Pittsburgh provide virtual
emergency neurologic care at
large numbers of hospitals. The
Mount Sinai system leverages spe-
cialists at eight hospitals and more
than 300 sites to provide virtual
emergency consultations and dis-
tribute work among subspecialty
providers. The barriers to imple-
menting these programs are large-
ly related to payment, credential-
ing, and staffing of specialists.
Reports that as many as 100
health care workers at a single in-
stitution have to be quarantined at
home because of exposure to
Covid-19 have raised concern about
workforce capacity. At institutions
with ED tele-intake or direct-to-
consumer care, quarantined phy-
sicians can cover those services,
freeing up other physicians to
perform in-person care. Office-
based practices can also employ
quarantined physicians to care for
patients remotely. The challenge
is that other health professionals
(nurses, medical assistants, phy-
sician assistants) also contribute
to in-person care, and telemedi-
cine cannot replace them all.
To prepare for the worst-case
scenario — a local pandemic that
leaves health care workers quar-
antined, sick, or absent — Jefferson
Health is deploying telehealth so

that clinicians can continue to
care for established (nonexposed)
patients by converting scheduled
office visits to telemedicine visits.
These visits can be conducted with
both patient and clinician at home,
greatly limiting travel and expo-
sure and permitting uninterrupt-
ed care of established patients.
Online training modules and re-
mote training sessions are avail-
able for clinicians or patients who
require just-in-time training or as-
sistance during their first call.
The main barriers to main-
taining usual care by telemedicine
require changes that are unlikely
to come from the federal level.
Commercial reimbursement, Med-
icaid reimbursement, and creden-
tialing are the states’ domain.
Only 20% of states require pay-
ment parity between telemedicine
and in-person services.5
Fortunate-
ly, both the Centers for Medicare
and Medicaid Services and some
local commercial payers have
modified payment policy in re-
sponse to Covid-19. We hope oth-
ers will follow suit.
Disasters and pandemics pose
unique challenges to health care
delivery. Though telehealth will
not solve them all, it’s well suited
for scenarios in which infrastruc-
ture remains intact and clinicians
are available to see patients.
Payment and regulatory struc-
tures, state licensing, credential-
ing across hospitals, and program
implementation all take time to
work through, but health systems
that have already invested in tele-
medicine are well positioned to
ensure that patients with Covid-19
receive the care they need. In this
instance, it may be a virtually per-
fect solution.

Virtually Perfect? Telemedicine for Covid-19

  • 1. Perspective The NEW ENGLAND JOURNAL of MEDICINE  n engl j med  nejm.org  1 R ecognizing that patients prioritize convenient and inexpensive care, Duffy and Lee recently asked whether in-person visits should be- come the second, third, or even last option for meeting patient needs.1 Previous work has specifically described the potential for using telemedicine in disasters and public health emergencies.2 No telemedicine program can be created over- night, but U.S. health systems that have already implemented telemedical innovations can lev- erage them for the response to Covid-19. A central strategy for health care surge control is “forward triage” — the sorting of patients before they arrive in the emergen- cy department (ED). Direct-to-con- sumer (or on-demand) telemedi- cine, a 21st-century approach to forward triage that allows pa- tients to be efficiently screened, is both patient-centered and con- ducive to self-quarantine, and it protects patients, clinicians, and the community from exposure. It can allow physicians and patients to communicate 24/7, using smart- phones or webcam-enabled com- puters. Respiratory symptoms — which may be early signs of Covid-19 — are among the con- ditions most commonly evaluated with this approach. Health care providers can easily obtain de- tailed travel and exposure histo- ries. Automated screening algo- rithms can be built into the intake process, and local epidemiologic information can be used to stan- dardize screening and practice patterns across providers. More than 50 U.S. health sys- tems already have such programs. Jefferson Health, Mount Sinai, Kaiser Permanente, Cleveland Clinic, and Providence, for ex- ample, all leverage telehealth tech- nology to allow clinicians to see patients who are at home. Systems lacking such programs can out- source similar services to physi- cians and support staff provided by Teladoc Health or American Well. At present, the major barrier to large-scale telemedical screen- ing for SARS-CoV-2, the novel co- ronavirus causing Covid-19, is coordination of testing. As the availability of testing sites ex- pands, local systems that can test appropriate patients while mini- mizing exposure — using dedi- cated office space, tents, or in-car testing — will need to be devel- oped and integrated into telemed- icine workflows. Rather than expect all outpa- tient practices to keep up with rap- idly evolving recommendations re- garding Covid-19, health systems have developed automated logic flows (bots) that refer moderate- to-high-risk patients to nurse tri- age lines but are also permitting patients to schedule video visits with established or on-demand providers, to avoid travel to in-per- son care sites.

When test- ing is needed, this approach re- quires centralized coordination with practice personnel as well as federal and local testing agencies. It is critical that practices not rou- tinely refer patients to EDs, urgent care centers, or offices, which risks exposure of other patients and health care providers. Patients presenting for in-per- son care who screen positive for high-risk features should be iso- lated immediately to avert further contact with patients and health care workers. Before the Covid-19 outbreak, many EDs modified the “provider-in-triage model” (rapid initial evaluation and testing) by allowing a remote provider to perform intake.3 Aurora Health, for example, partnered with a commercial telemedicine vendor, and others have developed their own software for this purpose. In an emergency situation, web- conferencing software with a se- cure open line from a triage room to a clinician can be implemented relatively rapidly. Covering multi- ple sites with a single remote cli- nician can address some work- force challenges, but it is difficult to do if your software lacks a queuing function. Tablet computers can be cleaned between patients using well-defined infection-control pro- cedures. In ambulatory care set- tings, patients screening positive at presentation can be given a tab- let and isolated in an exam room. A telehealth visit can be conducted without exposing staff by using commercial systems or paired tab- lets allowing communication with a clinician through a dedicated connection. Because of supply- chain challenges, we rapidly re- purposed and deployed tablets we already had. We expect that Covid-19 testing will be more widely available shortly, but initial- ly patients who were well enough to be sent home were quarantined there while home-based testing was coordinated. This system works for patients who are well but cannot totally eliminate health care workers’ exposure to sick patients who require procedures. Similar televisit systems are also being used for hospitalized pa- tients to reduce exposure risks for visitors and staff. Electronic intensive care unit (e-ICU) monitoring programs, which allow nurses and physi- cians to remotely monitor the sta- tus of 60 to 100 patients in ICUs in multiple hospitals — such as services offered by Mercy Virtual Care Center, Sutter Health, and Sentara Healthcare — are ideal for monitoring sicker patients. Technological and staffing com- plexities make it impossible to create such a program on short notice, but rapid deployment of the two-tablet approach can re- duce health care workers’ contact with infected patients in the ICU. Community paramedicine or mobile integrated health care pro- grams allow patients to be treated in their homes, with higher-level medical support provided virtu- ally. Houston’s Project ETHAN (Emergency Telehealth and Navi- gation) has used telemedical over- sight by physicians to augment care offered in person by 911 re- sponders, reducing the need for transportation to the ED.4 In the face of Covid-19, Avera Health is preparing to send mobile home health care units directly to pa- tients and is coordinating home- based testing. For sicker patients at home, such programs can fa- cilitate evaluation before hospital transfer, potentially allowing them to bypass the ED and be placed directly in a hospital bed, reducing exposure for health care workers and other patients. Much medical decision making is cognitive, and telemedicine can provide rapid access to subspecial- ists who aren’t immediately avail- able in person. This approach has been explored most fully in the context of stroke, for which sys- tems such as Jefferson Health, Cleveland Clinic, and the Univer- sity of Pittsburgh provide virtual emergency neurologic care at large numbers of hospitals. The Mount Sinai system leverages spe- cialists at eight hospitals and more than 300 sites to provide virtual emergency consultations and dis- tribute work among subspecialty providers. The barriers to imple- menting these programs are large- ly related to payment, credential- ing, and staffing of specialists. Reports that as many as 100 health care workers at a single in- stitution have to be quarantined at home because of exposure to Covid-19 have raised concern about workforce capacity. At institutions with ED tele-intake or direct-to- consumer care, quarantined phy- sicians can cover those services, freeing up other physicians to perform in-person care. Office- based practices can also employ quarantined physicians to care for patients remotely. The challenge is that other health professionals (nurses, medical assistants, phy- sician assistants) also contribute to in-person care, and telemedi- cine cannot replace them all. To prepare for the worst-case scenario — a local pandemic that leaves health care workers quar- antined, sick, or absent — Jefferson Health is deploying telehealth so The New England Journal of Medicine Downloaded from nejm.org on March 23, 2020.

  • 3. PERSPECTIVE 3 Virtually Perfect? Telemedicine for Covid-19 n engl j med  nejm.org  that clinicians can continue to care for established (nonexposed) patients by converting scheduled office visits to telemedicine visits. These visits can be conducted with both patient and clinician at home, greatly limiting travel and expo- sure and permitting uninterrupt- ed care of established patients. Online training modules and re- mote training sessions are avail- able for clinicians or patients who require just-in-time training or as- sistance during their first call. The main barriers to main- taining usual care by telemedicine require changes that are unlikely to come from the federal level. Commercial reimbursement, Med- icaid reimbursement, and creden- tialing are the states’ domain. Only 20% of states require pay- ment parity between telemedicine and in-person services.5 Fortunate- ly, both the Centers for Medicare and Medicaid Services and some local commercial payers have modified payment policy in re- sponse to Covid-19. We hope oth- ers will follow suit. Disasters and pandemics pose unique challenges to health care delivery. Though telehealth will not solve them all, it’s well suited for scenarios in which infrastruc- ture remains intact and clinicians are available to see patients. Payment and regulatory struc- tures, state licensing, credential- ing across hospitals, and program implementation all take time to work through, but health systems that have already invested in tele- medicine are well positioned to ensure that patients with Covid-19 receive the care they need. In this instance, it may be a virtually per- fect solution. Disclosure forms provided by the au- thors are available at NEJM.org.
