Telemedicine: The Future of Outpatient Therapy?
Lawrence Eron
John A. Burns School of Medicine, University of Hawaii, Kaiser
Moanalua Medical Center, Honolulu
Early hospital discharge of acutely infected patients to received
outpatient parenteral antimicrobial therapy
has been shown to be safe and effective. However, concerns
over safety, potential litigation, and anxieties of
the patient and family about not receiving professional care
have limited the use of this approach. Telemedicine
may overcome these barriers by allowing health care providers
to monitor and communicate with acutely
infected patients from a remote medical center via a home
computer station transmitting audio, video, and
vital signs data. Potential benefits of telemedicine include
significant cost savings and faster convalescence,
because patients at home may feel more comfortable and
actively involved in their treatment than patients
in the hospital. Clinical studies have shown that telemedicine is
safe and cost-effective, compared with hospital
treatment, in chronically ill and acutely infected patients. More
studies are needed to further establish the
widespread and increasing practice of telemedicine, which may
represent the future of medicine.
Early hospital discharge to use of outpatient parenteral
antimicrobial therapy (OPAT) has been shown to be
both safe and effective for the treatment of acutely in-
fected patients [1–5]. Conditions frequently treated in
this manner include community-acquired pneumonia
(CAP), skin and soft-tissue infection, urinary tract in-
fection, and bacterial endocarditis. However, OPAT
alone is not recommended for some patients with severe
illness or complications, including those who must be
monitored several times per day because of comorbid-
ities and/or low performance scores [6]. Furthermore,
the decision to discharge a patient to OPAT or to dis-
charge a patient who has been switched to oral anti-
biotics may be delayed because of persistent fever or
simply for a day of observation [4, 7, 8]. Routine in-
hospital observation after the oral switch is no longer
considered to be necessary or justifiable. However, a
survey of physicians responsible for deciding whether
to discharge patients with CAP revealed that the most
important factors defining clinical stability that sup-
ported the decision to discharge the patient included
normal temperature; return to baseline respiratory

status, mental status, and oxygenation; and the ability
to maintain oral intake of antibiotics [9]. The survey
respondents also believed that 120% of patients re-
mained in the hospital beyond the point at which they
had reached clinical stability. The most frequently cited
services that would definitely or probably have allowed
earlier hospital discharge were home intravenous an-
timicrobial treatment, home visits by nurses, and home
visits by physicians.
Early discharge may also present problems for pa-
tients who are still sick and, therefore, anxious about
not receiving professional care and for family members
who may be equally anxious about the patient’s safety
and intimidated by their responsibility for his or her
treatment. Physicians may also have some trepidation
about discharging patients to home before they are clin-
ically stable because of safety issues and the ever-present
problem of potential litigation. Discharge to home from
the emergency department or early in the course of
hospitalization of febrile, acutely infected patients is
now possible through the use of telemedicine [10].
TELEMEDICINE
The first formal and published definition of teleme-
dicine was “the practice of medicine without the usual
physician-patient confrontation…via [an] interactive
audio-video communication system” [11, p 614]. This
definition was soon expanded to include the concept

of telehealth, “a broad range of health-related activities, in-
cluding patient and provider education, and health services
administration, as well as patient care” [11, p 614]. Currently,
every state has at least one telemedicine program. Some are
statewide, offer a comprehensive range of clinical services and
continuing education, and involve a large number of hospitals
and clinics.
According to a 1997 survey of all nonfederal rural hospitals
in the United States [12], ∼1 in 4 had telemedicine programs,
although almost two-thirds were teleradiology. These applica-
tions have led to the hub-and-spoke concept, whereby rural
hospitals are connected to tertiary care centers by telemedicine.
To date, ∼200 such networks are operating in the United States,
linking 13500 institutions nationwide [13].
Transmission of video images, audio, and vital signs data
from a remote site to a central location has been used in homes
to monitor chronically ill patients, including those with con-
gestive heart failure, chronic obstructive pulmonary disease,
and diabetes mellitus [10]. In a home health care study by a
nonprofit health maintenance organization, chronically ill pa-
tients who were eligible for home health care were offered
either
routine in-person and phone visits or the routine program and
telemedicine visits [14]. Routine care included initial assess-
ment in the home and in-person follow-up by nurses, as well
as the ability of the patient to reach a home health nurse by
phone from 8:30 AM through 5:00 PM for additional infor-
mation or triage. Additional verbal contact after normal work-
ing hours was available through the hospital’s telephone advice
center or at the emergency department. Patients also had the
option of being transported to an emergency department or
urgent care clinic for assessment if necessary.
The telemedicine intervention group had access to a home
health nurse 24 h per day; an on-call home health nurse could
contact the patient using the remote video equipment, which
allows in-depth assessment and triage without patients having
to leave home [14]. Installation of the home video system and
instruction of the patient in its use required ∼30 min. Peripheral
units of the system included an analog stethoscope and a digital
blood pressure machine; thus, nurses at the hospital site were
able to assess cardiopulmonary status, evaluate bowel sounds,
and view facial expression and signs of infection. A magnifying
lens that attached to the camera was used to assess correct
medication doses when patients were being taught how to use
medications, such as insulin.
No differences in the quality indicators (ie, medication com-
pliance, knowledge of disease, and ability for self care), patient
satisfaction, or use were seen. Moreover, the video technology
in the home health care setting yielded mean cost savings per
patient, although the savings were less than expected because
the intervention included the full cost of equipment and tel-
ecommunications start-up; in practice, the equipment would
be leased or amortized over several years. The investigators
concluded that telemedicine can be an asset for patients and
providers and has the potential to reduce costs [14]. However,
these results are based on a nonrandomized, case-control study,
which could have introduced biases into the conclusions.
TELEMEDICINE AND ACUTE CARE
Adaptation of telemedicine to the home care of acutely infected
patients who would normally be hospitalized was introduced
in a 2004 pilot study comparing 25 moderately to severely ill
patients treated by telemedicine in the home with a control
group that remained in the hospital [10]. The study was at
least partially based on a 2001 observational study that chal-
lenged the conventional hospital discharge process for patients
admitted with an acute infection [4]. According to this process,
patients undergo 3 stages of recovery from a severe infection
(Figure 1). Stage 1 extends from admission to clinical stability,
implying that the condition of the patient is no longer wors-
ening and has thus stabilized [10], and stage 2 devolves to early
improvement, suggesting a trend toward normality of temper-
ature and other inflammatory indicators. By the end of stage
3, which represents normalization of most clinical parameters,
the patient is sufficiently healthy to be discharged. The out-
comes in acutely infected patients with cellulitis, CAP, and uri-
nary tract infection who were discharged after defervescence
and definite clinical improvement were compared with those
in similarly infected patients discharged while still febrile (Fig-
ure 2) [4]. In addition to a shorter mean length of hospital
stay, patients discharged early returned to normal activities of
daily living more rapidly than did those whose discharge re-
quired a return of normal temperature.
In the 2004 study, patients with CAP, skin and soft-tissue
infections, urinary tract infection, and bacterial endocarditis
were referred from either the emergency department or the
hospital for telemedicine in the home [10]. Inclusion criteria
included a home with a person to assist the patient, willingness
to self-administer intravenous antibiotics when necessary, and
a low predicted 30-day mortality rate. Patients had to be ill

enough to require hospitalization but not intensive care mon-
itoring. These patients were not conventional home-care or
OPAT candidates. All were screened for severity of illness, and
those with mild or life-threatening infections were excluded.
Of 41 patients evaluated using the Karnofsky performance scale
[15] and the Charlson comorbidity index [16, 17], 25 were
candidates for telemedicine in the home. Examples of the types
of treated patients are shown in Table 1 [10].
The Karnofsky performance scale measures a patient’s ability
to perform activities of daily living from 100% (ie, normal, no
complaints, and no evidence of disease) to 10% (ie, moribund,
with fatal processes progressing rapidly) and 0% [15]. The
Charlson comorbidity index, originally designed to classify
prognostic comorbidity in longitudinal studies, uses age and
specific comorbidities to predict survival [16, 17]. The score is
calculated for each patient as the total of the patient’s comorbid
conditions, which are weighted. Thus, a patient with moderately
severe CAP may have a high pneumonia severity index but can
still be treated as an outpatient if he or she has a reasonably
high Karnofsky score of 80% (ie, normal activity with effort
and some signs and symptoms of disease). The opposite is also
true: a patient with mild CAP and a low pneumonia severity
index may be at high risk on the basis of a low Karnofsky score
and a number of comorbidities.
Telemedicine equipment consisted of an Aviva Tower central
station and 4 Aviva 1010 XR patient stations, with a station
kept in reserve [18]. The connection between each patient’s
home station and the central station in the hospital was through
plain old telephone service lines. The telemedicine team in-
cluded a physician, 2 nurse practitioners, an information tech-
nology consultant, and a project coordinator.
After discharge from the hospital, telemedicine candidates
were met in the home by a member of the telemedicine team
who had transported the patient’s telemedicine equipment, or
station [10]. Installment of the station required a nearby tele-
phone outlet, through which the audiovisual and vital signs
were
transmitted, and adequate lighting. A second member of the
team, a nurse practitioner or physician, communicated with the
patient from a central station at the hospital (Figure 3) [10].
Eight patients started home telemedicine without being hos-
pitalized; 12 had been hospitalized for �4 days, and 5 had been
hospitalized for 5–10 days before discharge. The mean number
of combined hospital and home televisit days (8.3 days) was
similar to the mean duration of hospitalization (8.0 days) in
the control group.
None of the telemedicine patients had to be rehospitalized,
although 3 had recurrent infections. Three control patients had
recurrent CAP, and 1 of these patients was readmitted to the
hospital. A fourth control patient experienced nosocomial Clos-
tridium difficile enterocolitis. Patients receiving telemedicine
re-
turned to normal activities of daily living several weeks earlier
than did control subjects (Table 2) [10].
TELEMEDICINE COSTS
On the basis of the projected enrollment of 50 patients by the
end of 1 year, the number of hospital-days for control subjects
(8 days) and patients receiving telemedicine (2.8 days), and the
hypothesis that each telemedicine-day equals 1 hospital-day
saved [10], the trial investigators calculated that telemedicine
would have saved up to 5.2 days (range, 2.8–8.0 days) of hos-
pitalization for each patient treated, or 260 ( ) patient-5.2 � 50
days per year. Because the cost of a hospital bed is $500–$2000
per day, the pilot trial would have saved $130,000–$520,000 in
one year.
The cost of equipment (amortized over 2 years), personnel,
and information technology consultation amounted to
$120,000. Thus, the program would have netted $10,000–
$400,000 in 1 year [10].
TELEMEDICINE REIMBURSEMENT
Medicare
Clinical services. Although the Balanced Budget Act of 1997
mandated that Medicare reimburse telemedicine services to phy-
sicians on a fee-for-service basis, it also required the presence
of
a Medicare-participating telepresenter (a clinician at the patient
end of the televisit) [19]. This mandate, in addition to the lim-
itations on the telecommunications infrastructure in remote or
hostile environments, meant that only live telemedicine services
(10% of the total) were cost-effective. Moreover, an additional
requirement that the telepresenter and the consulting physician
share the fee suggested the potential for violating Medicare’s
own
prohibition against payment for referrals.
The 2000 omnibus appropriations bill HR 5661 dramatically
revised Medicare rules for reimbursement as of 1 October 2001.
The revisions included elimination of the requirement for a
Medicare-participating telepresenter; expansion of telemedicine
services to include direct patient care, physician consultations,

Home care. Medicare’s Prospective Payment System pro-
vides a fixed payment for each Medicare beneficiary for a 60-
day period on the basis of the assigned Home Health Resource
Group, which in turn provides a fixed payment for an unlimited
number of medically necessary episodes of care [20]. The per-
episode payment covers all skilled nursing visits, home health
aide visits, physical therapy, occupational therapy, speech pa-
thology, medical social services, and nonroutine medical sup-
plies. Payment is adjusted according to the number of necessary
visits, which reflects severity of illness.
The Prospective Payment System creates an incentive for
home health providers to proactively manage the delivery of
care and to use innovative means to deliver care while reducing
costs. When costs are lower than Medicare payment rates, pro-
viders are entitled to retain the difference as a profit. Although
HR5661 specifically permits the use of telemedicine services to
satisfy home health care delivery obligations under the Pro-
spective Payment System, telemedicine visits do not constitute
a visit under the Outcome Assessment and Information Set
evaluation tool [21] for purposes of determining assignment
to a Home Health Resource Group. Therefore, home care pro-
viders should assess the benefits of telemedicine services and
the effect that substitution of telemedicine visits will have on
reimbursement in accordance with the Medicare Prospective
Payment System.
Medicaid
Many states that struggle to find cost-effective ways to provide
care and to seek reducing geographic and provider-network
barriers have considered telemedicine programs. However, not
all states have embraced this technology, in part because of
significant challenges involving service reimbursement. State
Medicaid programs vary with regard to whether they provide
telemedicine and how they structure it. A nationwide survey
of Medicaid programs regarding telemedicine services was pub-
lished in 2005 [22]. Although focused on children with special
health care needs, the survey’s first goal was to identify
common
strategies related to Medicaid reimbursement.
Among the 50 states surveyed, Medicaid programs in 24
states reported that they reimburse for telemedicine, and pro-
grams in 4 were planning to implement reimbursement in the
future [22]. All 24 programs reimbursed for some physician
consultations via video teleconferencing; 19 reimbursed for
real-time consultations only, and of these, 3 specified that the
patient must be present at the time of consultation. The most
common reimbursable services are medical and behavioral and/
or mental health diagnostic consultations or treatments. Lim-
itations on service included reimbursement for behavioral and/
or mental health only (1 state), no reimbursement for mental
health (1), no reimbursement for ancillary services (2), reim-
bursement only when the spoke site is in the hospital emergency
department or outpatient setting (1), and reimbursement only
to clients enrolled in fee-for-service Medicaid (3). Licensed
physicians are reimbursed in all 24 states. In general, any pro-

vider who billed for face-to-face visits could bill for teleme-
dicine. All 24 states reimbursed in accordance with fee-for-
service arrangements.
Twenty-two states reported that Medicaid does not reim-
burse, including 1 state that discontinued telemedicine reim-
bursement after determining that it was not cost-effective [22].
Medicaid programs in 4 of the 22 states have ongoing pilot
projects and expressed the intent to establish a reimbursement
program.
Commercial Insurers
Payment policies for telemedicine services vary widely among
commercial insurers [19]. An organization may have the lev-
erage to require payment for such services as a condition to
enter a contract before negotiation. On the other hand, con-
tracts that do not specifically provide for payments for tele-
medicine services may incorporate reference to Medicare for
coverage of services rules. Finally, it is advisable to consult
with
legal counsel or contracting specialists to determine whether
contracts provide, directly or indirectly, for reimbursement.
The recognition of telemedicine visits as allowable visits for
reimbursement varies among insurers [19]. Many are interested
in demonstration projects to provide treatment to chronically
ill patients, and some allow payment for telemedicine-based
equipment in the home.
Although the lack of private payer reimbursement has been
seen as a major barrier to the acceptance and growth of tele-
medicine, a 2003 survey of members of the American Tele-
medicine Association found that 38 of 72 programs were re-
ceiving reimbursement from private payers [23]. At that time,
payers were reimbursing in at least 25 states. Moreover, in
many
cases, payers were following the lead of Blue Cross/Blue Shield
rather than Medicaid and/or Medicare.
As of 2000, 5 states (California, Kentucky, Louisiana,
Oklahoma, and Texas) had passed legislation mandating private
payer reimbursement for telemedicine services [23]. For ex-
ample, Oklahoma’s SB 48 (1997) provides that health care plans
cannot deny coverage for health care services provided through
audio, video, or data communications. This would allow com-
pensation for patient consultations, diagnoses, and the transfer
of medical data through telecommunication technology. The
measure excludes telephone and facsimile communications
from the term “telemedicine.” Kentucky’s HB 177 (2000) pro-
hibits Medicaid and private insurers from requiring face-to-
face contact between a health care provider and patient for
services appropriately provided through telemedicine, subject
to the terms of the contract.
A follow-up survey in 2007 found that at least 35 states were
receiving Medicaid reimbursement for telemedicine services,
with the same mandates in the same 5 states [24]. A total of
116 telemedicine programs were identified, with a 55% re-
sponse rate. Of the 64 respondents, 61 provide billable services
and 58% receive private pay (42% do not). The percentage of
programs receiving private payer reimbursement increased by
5% from 2003. The majority of programs (81%) reported no
difference in the amount of reimbursement between teleme-
dicine services and traditional consultations.

lems, patient and clinician acceptance, reimbursement from
third-party payers, and legal challenges [10]. Technical prob-
lems, such as video freeze-ups and spontaneous termination of
connections caused by the low bandwidths of plain old tele-
phone service, remain for many programs because of the lack
of available broadband service in some areas. (In Hawaii, how-
ever, 80% of homes have cable service [Time Warner Oceanic
Cable] through which broadband service is available for tele-
medicine communication.) Although catastrophic earthquakes,
as occurred in 2010 in Haiti and Chile, could disrupt telephone
and cable lines, crippling snowstorms, such as the ones in the
United States and Europe during the winter of 2009–2010 that
shut down transportation services to and from hospitals and
clinics, should not interfere with telehealth visits between pro-
viders and patients.
Although patients treated by telemedicine have had satisfac-
tory clinical outcomes, more rapid convalescence, and increased
comfort at home, some patients have reported feeling safer in
a hospital environment than at home. Care providers may be
unwilling to bear the entire burden of caring for a patient; it
may be necessary to provide respite workers to shop, cook, and
clean and to provide companionship for some patients.
In general, clinicians remain skeptical about whether the
evidence is sufficient to change the current practice of not
discharging febrile patients before clinical improvement is
achieved. This reaction may be based on traditional teachings
and clinicians’ fear of unsuccessful outcomes and, in turn, the
potential threat of litigation. Telemedicine may increase the
work load of physicians. Appropriate compensation will be a
prerequisite to physician buy-in. Some believe that use of tel-
ecommunications technology threatens basic components of
medical care. One author warned “against excessive reliance on
technology to the detriment of traditional clinician-patient re-
lationships and against complacency regarding the risks and
responsibilities—many of which are as yet unknown—that dis-
tant medical intervention, consultation, and diagnosis carry”
[25, p 615]. The author emphasized that an intangible aspect
of traditional health care is threatened, specifically “the comfort
and compassion human beings can only bring each other when
they are face to face” [25].
Despite a large number of success stories attesting to the
cost-effectiveness of telemedicine in the home, not all com-
mercial third-party insurers reimburse for home televisits. More
positive outcome-based data from randomized comparison
studies are needed to confirm the efficacy and cost savings of
home telemedicine.
Medical-legal challenges for poor outcomes related to tele-
medicine in the home may occur, as did during the early days
of OPAT 13 decades ago. With time and satisfactory outcomes
data, however, OPAT became a standard of care, and fear of
litigation dissipated.
CONCLUSION
Telemedicine in the home has several advantages over hospi-
talization. It promotes more efficient use of hospital beds, re-
sulting in cost savings, and patients tend to convalesce more
rapidly at home. This latter phenomenon may be related to
several factors, including removal of the patient from a passive-
dependent posture in the hospital to more active participation
in his or her own medical care at home. The active involvement
of patients in their own care results in a sense of empowerment
over their illness.
Although the clinical use of telemedicine in the United States
is still limited, in the future, there may be increased numbers
of health care providers seeing patients at remote sites on a
desktop or laptop computer. Clinicians will select interactive
video and store-and-forward modes as needed and seamless
access to pertinent patient records, radiographs, pathology
slides, pharmacy information, and billing records. They will
have at hand the content of online libraries of medical infor-
mation, diagnosis and treatment algorithms, and patient in-
structional materials. Referral to specialists and allied health
personnel will be made by computer-based scheduling. Patient
information will be stored in archives accessed by authorized
medical personnel anywhere in the world.

S230 • CID 2010:51 (Suppl 2) • Eron
As both a means of communication and a new diagnostic
and therapeutic modality, telemedicine should be approached
with scientific skepticism and caution. Research into its safety,
efficacy, cost-effectiveness, and patient and clinician
satisfaction
must be a high priority. Telemedicine may still be medicine at
a distance, but its range of applications has changed it from a
technological augmentation of medical care to a novel system
of health care. This integration of information technology with
the health care system is a process that will redefine future
medical care.

However, concerns over safety, potential litigation, and anxieties of the patient and family about not receiving professional care have limited the use of this approach. Telemedicine may overcome these barriers by allowing health care providers to monitor and communicate with acutely infected patients from a remote medical center via a home computer station transmitting audio, video, and vital signs data. Potential benefits of telemedicine include significant cost savings and faster convalescence, because patients at home may feel more comfortable and actively involved in their treatment than patients in the hospital. Clinical studies have shown that telemedicine is safe and cost-effective, compared with hospital treatment, in chronically ill and acutely infected patients. More studies are needed to further establish the widespread and increasing practice of telemedicine, which may represent the future of medicine. Early hospital discharge to use of outpatient parenteral antimicrobial therapy (OPAT) has been shown to be both safe and effective for the treatment of acutely in- fected patients [1–5]. Conditions frequently treated in this manner include community-acquired pneumonia

However, OPAT alone is not recommended for some patients with severe illness or complications, including those who must be monitored several times per day because of comorbid- ities and/or low performance scores [6]. Furthermore, the decision to discharge a patient to OPAT or to dis- charge a patient who has been switched to oral anti- biotics may be delayed because of persistent fever or simply for a day of observation [4, 7, 8]. Routine in- hospital observation after the oral switch is no longer considered to be necessary or justifiable. However, a survey of physicians responsible for deciding whether to discharge patients with CAP revealed that the most important factors defining clinical stability that sup- ported the decision to discharge the patient included normal temperature; return to baseline respiratory Reprints or correspondence: Dr Lawrence Eron, 3288 Moanalua

The survey respondents also believed that 120% of patients re- mained in the hospital beyond the point at which they had reached clinical stability. The most frequently cited services that would definitely or probably have allowed earlier hospital discharge were home intravenous an- timicrobial treatment, home visits by nurses, and home visits by physicians. Early discharge may also present problems for pa- tients who are still sick and, therefore, anxious about not receiving professional care and for family members who may be equally anxious about the patient’s safety and intimidated by their responsibility for his or her

Physicians may also have some trepidation about discharging patients to home before they are clin- ically stable because of safety issues and the ever-present problem of potential litigation. Discharge to home from the emergency department or early in the course of hospitalization of febrile, acutely infected patients is now possible through the use of telemedicine [10]. TELEMEDICINE The first formal and published definition of teleme- dicine was “the practice of medicine without the usual physician-patient confrontation…via [an] interactive audio-video communication system” [11, p 614]. This definition was soon expanded to include the concept a t U n ive rsity o f C

  • 8. cluding patient and provider education, and health services administration, as well as patient care” [11, p 614]. Currently, every state has at least one telemedicine program. Some are statewide, offer a comprehensive range of clinical services and continuing education, and involve a large number of hospitals and clinics. According to a 1997 survey of all nonfederal rural hospitals in the United States [12], ∼1 in 4 had telemedicine programs, although almost two-thirds were teleradiology. These applica- tions have led to the hub-and-spoke concept, whereby rural hospitals are connected to tertiary care centers by telemedicine. To date, ∼200 such networks are operating in the United States, linking 13500 institutions nationwide [13]. Transmission of video images, audio, and vital signs data from a remote site to a central location has been used in homes to monitor chronically ill patients, including those with con- gestive heart failure, chronic obstructive pulmonary disease, and diabetes mellitus [10]. In a home health care study by a nonprofit health maintenance organization, chronically ill pa-
  • 9. tients who were eligible for home health care were offered either routine in-person and phone visits or the routine program and telemedicine visits [14]. Routine care included initial assess- ment in the home and in-person follow-up by nurses, as well as the ability of the patient to reach a home health nurse by phone from 8:30 AM through 5:00 PM for additional infor- mation or triage. Additional verbal contact after normal work- ing hours was available through the hospital’s telephone advice center or at the emergency department. Patients also had the option of being transported to an emergency department or urgent care clinic for assessment if necessary. The telemedicine intervention group had access to a home health nurse 24 h per day; an on-call home health nurse could contact the patient using the remote video equipment, which allows in-depth assessment and triage without patients having to leave home [14]. Installation of the home video system and instruction of the patient in its use required ∼30 min. Peripheral units of the system included an analog stethoscope and a digital
  • 10. blood pressure machine; thus, nurses at the hospital site were able to assess cardiopulmonary status, evaluate bowel sounds, and view facial expression and signs of infection. A magnifying lens that attached to the camera was used to assess correct medication doses when patients were being taught how to use medications, such as insulin. No differences in the quality indicators (ie, medication com- pliance, knowledge of disease, and ability for self care), patient satisfaction, or use were seen. Moreover, the video technology in the home health care setting yielded mean cost savings per patient, although the savings were less than expected because the intervention included the full cost of equipment and tel- ecommunications start-up; in practice, the equipment would be leased or amortized over several years. The investigators concluded that telemedicine can be an asset for patients and providers and has the potential to reduce costs [14]. However, these results are based on a nonrandomized, case-control study, which could have introduced biases into the conclusions.
  • 11. TELEMEDICINE AND ACUTE CARE Adaptation of telemedicine to the home care of acutely infected patients who would normally be hospitalized was introduced in a 2004 pilot study comparing 25 moderately to severely ill patients treated by telemedicine in the home with a control group that remained in the hospital [10]. The study was at least partially based on a 2001 observational study that chal- lenged the conventional hospital discharge process for patients admitted with an acute infection [4]. According to this process, patients undergo 3 stages of recovery from a severe infection (Figure 1). Stage 1 extends from admission to clinical stability, implying that the condition of the patient is no longer wors- ening and has thus stabilized [10], and stage 2 devolves to early improvement, suggesting a trend toward normality of temper- ature and other inflammatory indicators. By the end of stage 3, which represents normalization of most clinical parameters, the patient is sufficiently healthy to be discharged. The out- comes in acutely infected patients with cellulitis, CAP, and uri-

In addition to a shorter mean length of hospital stay, patients discharged early returned to normal activities of daily living more rapidly than did those whose discharge re- quired a return of normal temperature. In the 2004 study, patients with CAP, skin and soft-tissue infections, urinary tract infection, and bacterial endocarditis were referred from either the emergency department or the hospital for telemedicine in the home [10]. Inclusion criteria included a home with a person to assist the patient, willingness to self-administer intravenous antibiotics when necessary, and a low predicted 30-day mortality rate. Patients had to be ill a t U n ive rsity o

All were screened for severity of illness, and those with mild or life-threatening infections were excluded. Of 41 patients evaluated using the Karnofsky performance scale [15] and the Charlson comorbidity index [16, 17], 25 were candidates for telemedicine in the home. Examples of the types of treated patients are shown in Table 1 [10]. The Karnofsky performance scale measures a patient’s ability to perform activities of daily living from 100% (ie, normal, no complaints, and no evidence of disease) to 10% (ie, moribund, with fatal processes progressing rapidly) and 0% [15]. The Charlson comorbidity index, originally designed to classify prognostic comorbidity in longitudinal studies, uses age and specific comorbidities to predict survival [16, 17]. The score is calculated for each patient as the total of the patient’s comorbid conditions, which are weighted. Thus, a patient with moderately
  • 16. severe CAP may have a high pneumonia severity index but can still be treated as an outpatient if he or she has a reasonably high Karnofsky score of 80% (ie, normal activity with effort and some signs and symptoms of disease). The opposite is also true: a patient with mild CAP and a low pneumonia severity index may be at high risk on the basis of a low Karnofsky score and a number of comorbidities. Telemedicine equipment consisted of an Aviva Tower central station and 4 Aviva 1010 XR patient stations, with a station kept in reserve [18]. The connection between each patient’s home station and the central station in the hospital was through plain old telephone service lines. The telemedicine team in- cluded a physician, 2 nurse practitioners, an information tech- nology consultant, and a project coordinator. After discharge from the hospital, telemedicine candidates were met in the home by a member of the telemedicine team who had transported the patient’s telemedicine equipment, or station [10]. Installment of the station required a nearby tele-
  • 17. phone outlet, through which the audiovisual and vital signs were transmitted, and adequate lighting. A second member of the team, a nurse practitioner or physician, communicated with the patient from a central station at the hospital (Figure 3) [10]. Eight patients started home telemedicine without being hos- pitalized; 12 had been hospitalized for �4 days, and 5 had been hospitalized for 5–10 days before discharge. The mean number of combined hospital and home televisit days (8.3 days) was similar to the mean duration of hospitalization (8.0 days) in the control group. None of the telemedicine patients had to be rehospitalized, although 3 had recurrent infections. Three control patients had recurrent CAP, and 1 of these patients was readmitted to the hospital. A fourth control patient experienced nosocomial Clos- tridium difficile enterocolitis. Patients receiving telemedicine re- turned to normal activities of daily living several weeks earlier than did control subjects (Table 2) [10].
  • 18. TELEMEDICINE COSTS On the basis of the projected enrollment of 50 patients by the end of 1 year, the number of hospital-days for control subjects (8 days) and patients receiving telemedicine (2.8 days), and the hypothesis that each telemedicine-day equals 1 hospital-day saved [10], the trial investigators calculated that telemedicine would have saved up to 5.2 days (range, 2.8–8.0 days) of hos- pitalization for each patient treated, or 260 ( ) patient-5.2 � 50 days per year. Because the cost of a hospital bed is $500–$2000 per day, the pilot trial would have saved $130,000–$520,000 in one year. The cost of equipment (amortized over 2 years), personnel, and information technology consultation amounted to $120,000. Thus, the program would have netted $10,000– $400,000 in 1 year [10]. TELEMEDICINE REIMBURSEMENT Medicare Clinical services. Although the Balanced Budget Act of 1997
  • 19. mandated that Medicare reimburse telemedicine services to phy- sicians on a fee-for-service basis, it also required the presence of a Medicare-participating telepresenter (a clinician at the patient end of the televisit) [19]. This mandate, in addition to the lim- itations on the telecommunications infrastructure in remote or hostile environments, meant that only live telemedicine services (10% of the total) were cost-effective. Moreover, an additional requirement that the telepresenter and the consulting physician share the fee suggested the potential for violating Medicare’s own prohibition against payment for referrals. The 2000 omnibus appropriations bill HR 5661 dramatically revised Medicare rules for reimbursement as of 1 October 2001. The revisions included elimination of the requirement for a Medicare-participating telepresenter; expansion of telemedicine services to include direct patient care, physician consultations, a t U n

Home care. Medicare’s Prospective Payment System pro- vides a fixed payment for each Medicare beneficiary for a 60- day period on the basis of the assigned Home Health Resource Group, which in turn provides a fixed payment for an unlimited
  • 24. number of medically necessary episodes of care [20]. The per- episode payment covers all skilled nursing visits, home health aide visits, physical therapy, occupational therapy, speech pa- thology, medical social services, and nonroutine medical sup- plies. Payment is adjusted according to the number of necessary visits, which reflects severity of illness. The Prospective Payment System creates an incentive for home health providers to proactively manage the delivery of care and to use innovative means to deliver care while reducing costs. When costs are lower than Medicare payment rates, pro- viders are entitled to retain the difference as a profit. Although HR5661 specifically permits the use of telemedicine services to satisfy home health care delivery obligations under the Pro- spective Payment System, telemedicine visits do not constitute a visit under the Outcome Assessment and Information Set evaluation tool [21] for purposes of determining assignment to a Home Health Resource Group. Therefore, home care pro- viders should assess the benefits of telemedicine services and
  • 25. the effect that substitution of telemedicine visits will have on reimbursement in accordance with the Medicare Prospective Payment System. Medicaid Many states that struggle to find cost-effective ways to provide care and to seek reducing geographic and provider-network barriers have considered telemedicine programs. However, not all states have embraced this technology, in part because of significant challenges involving service reimbursement. State Medicaid programs vary with regard to whether they provide telemedicine and how they structure it. A nationwide survey of Medicaid programs regarding telemedicine services was pub- lished in 2005 [22]. Although focused on children with special health care needs, the survey’s first goal was to identify common strategies related to Medicaid reimbursement. Among the 50 states surveyed, Medicaid programs in 24 states reported that they reimburse for telemedicine, and pro-
  • 26. grams in 4 were planning to implement reimbursement in the future [22]. All 24 programs reimbursed for some physician consultations via video teleconferencing; 19 reimbursed for real-time consultations only, and of these, 3 specified that the patient must be present at the time of consultation. The most common reimbursable services are medical and behavioral and/ or mental health diagnostic consultations or treatments. Lim- itations on service included reimbursement for behavioral and/ or mental health only (1 state), no reimbursement for mental health (1), no reimbursement for ancillary services (2), reim- bursement only when the spoke site is in the hospital emergency department or outpatient setting (1), and reimbursement only to clients enrolled in fee-for-service Medicaid (3). Licensed physicians are reimbursed in all 24 states. In general, any pro- a t U n ive rsity o f C

Twenty-two states reported that Medicaid does not reim- burse, including 1 state that discontinued telemedicine reim- bursement after determining that it was not cost-effective [22]. Medicaid programs in 4 of the 22 states have ongoing pilot projects and expressed the intent to establish a reimbursement program. Commercial Insurers Payment policies for telemedicine services vary widely among commercial insurers [19]. An organization may have the lev- erage to require payment for such services as a condition to enter a contract before negotiation. On the other hand, con- tracts that do not specifically provide for payments for tele- medicine services may incorporate reference to Medicare for coverage of services rules. Finally, it is advisable to consult with legal counsel or contracting specialists to determine whether contracts provide, directly or indirectly, for reimbursement.
  • 30. The recognition of telemedicine visits as allowable visits for reimbursement varies among insurers [19]. Many are interested in demonstration projects to provide treatment to chronically ill patients, and some allow payment for telemedicine-based equipment in the home. Although the lack of private payer reimbursement has been seen as a major barrier to the acceptance and growth of tele- medicine, a 2003 survey of members of the American Tele- medicine Association found that 38 of 72 programs were re- ceiving reimbursement from private payers [23]. At that time, payers were reimbursing in at least 25 states. Moreover, in many cases, payers were following the lead of Blue Cross/Blue Shield rather than Medicaid and/or Medicare. As of 2000, 5 states (California, Kentucky, Louisiana, Oklahoma, and Texas) had passed legislation mandating private payer reimbursement for telemedicine services [23]. For ex- ample, Oklahoma’s SB 48 (1997) provides that health care plans
  • 31. cannot deny coverage for health care services provided through audio, video, or data communications. This would allow com- pensation for patient consultations, diagnoses, and the transfer of medical data through telecommunication technology. The measure excludes telephone and facsimile communications from the term “telemedicine.” Kentucky’s HB 177 (2000) pro- hibits Medicaid and private insurers from requiring face-to- face contact between a health care provider and patient for services appropriately provided through telemedicine, subject to the terms of the contract. A follow-up survey in 2007 found that at least 35 states were receiving Medicaid reimbursement for telemedicine services, with the same mandates in the same 5 states [24]. A total of 116 telemedicine programs were identified, with a 55% re- sponse rate. Of the 64 respondents, 61 provide billable services and 58% receive private pay (42% do not). The percentage of programs receiving private payer reimbursement increased by 5% from 2003. The majority of programs (81%) reported no

Technical prob- lems, such as video freeze-ups and spontaneous termination of connections caused by the low bandwidths of plain old tele- phone service, remain for many programs because of the lack of available broadband service in some areas. (In Hawaii, how- ever, 80% of homes have cable service [Time Warner Oceanic Cable] through which broadband service is available for tele- medicine communication.) Although catastrophic earthquakes, as occurred in 2010 in Haiti and Chile, could disrupt telephone and cable lines, crippling snowstorms, such as the ones in the United States and Europe during the winter of 2009–2010 that shut down transportation services to and from hospitals and clinics, should not interfere with telehealth visits between pro- viders and patients.
  • 36. Although patients treated by telemedicine have had satisfac- tory clinical outcomes, more rapid convalescence, and increased comfort at home, some patients have reported feeling safer in a hospital environment than at home. Care providers may be unwilling to bear the entire burden of caring for a patient; it may be necessary to provide respite workers to shop, cook, and clean and to provide companionship for some patients. In general, clinicians remain skeptical about whether the evidence is sufficient to change the current practice of not discharging febrile patients before clinical improvement is achieved. This reaction may be based on traditional teachings and clinicians’ fear of unsuccessful outcomes and, in turn, the potential threat of litigation. Telemedicine may increase the work load of physicians. Appropriate compensation will be a prerequisite to physician buy-in. Some believe that use of tel- ecommunications technology threatens basic components of medical care. One author warned “against excessive reliance on technology to the detriment of traditional clinician-patient re-
  • 37. lationships and against complacency regarding the risks and responsibilities—many of which are as yet unknown—that dis- tant medical intervention, consultation, and diagnosis carry” [25, p 615]. The author emphasized that an intangible aspect of traditional health care is threatened, specifically “the comfort and compassion human beings can only bring each other when they are face to face” [25]. Despite a large number of success stories attesting to the cost-effectiveness of telemedicine in the home, not all com- mercial third-party insurers reimburse for home televisits. More positive outcome-based data from randomized comparison studies are needed to confirm the efficacy and cost savings of home telemedicine. Medical-legal challenges for poor outcomes related to tele- medicine in the home may occur, as did during the early days of OPAT 13 decades ago. With time and satisfactory outcomes data, however, OPAT became a standard of care, and fear of litigation dissipated.
  • 38. CONCLUSION Telemedicine in the home has several advantages over hospi- talization. It promotes more efficient use of hospital beds, re- sulting in cost savings, and patients tend to convalesce more rapidly at home. This latter phenomenon may be related to several factors, including removal of the patient from a passive- dependent posture in the hospital to more active participation in his or her own medical care at home. The active involvement of patients in their own care results in a sense of empowerment over their illness. Although the clinical use of telemedicine in the United States is still limited, in the future, there may be increased numbers of health care providers seeing patients at remote sites on a desktop or laptop computer. Clinicians will select interactive video and store-and-forward modes as needed and seamless access to pertinent patient records, radiographs, pathology slides, pharmacy information, and billing records. They will have at hand the content of online libraries of medical infor-
  • 39. mation, diagnosis and treatment algorithms, and patient in- structional materials. Referral to specialists and allied health personnel will be made by computer-based scheduling. Patient information will be stored in archives accessed by authorized medical personnel anywhere in the world. a t U n ive rsity o f C a lifo rn ia , S a n F ra n cisco o

Research into its safety, efficacy, cost-effectiveness, and patient and clinician satisfaction must be a high priority. Telemedicine may still be medicine at a distance, but its range of applications has changed it from a technological augmentation of medical care to a novel system of health care. This integration of information technology with the health care system is a process that will redefine future medical care. Acknowledgments
