SYSTEM AND METHOD FOR PATIENT DATA PROCESSING
DURING DIAGNOSIS AND THERAPY
1 BACKGROUND
Ll FIELD OF THE TECHNOLOGY
The present technolcigy relates to the diagnosis and treatment of
atory-related disorders.
1.2 DESCRIPTION OF THE D ART
1.2.1 Human Respiratory System and its Disorders
{0063] The respiratory system of the body facilitates gas exchange. The nose and
mouth form the entrance to the airways 017a patient.
{0003] The airways include a series of branching tubes, which becmne narrower,
short-er and more numerous as they penetrate deeper into the lung. The prime function
of the lung is gas ge, allowing oxygen to move from the air into {he venous
bleed and carbon dioxide to meve out. The trachea divides into right and. left main
brenehi, Which further divide eventually into terminal oies. The bronchi make
up the conducting airways, and do not take part in gas exchange. Further divisions; of
the airways lead to the respiramry hronehiolesq and eventually to the i. The
alveolated region of the lung is where the gas ge takes place, and is referred to
as the atory mne. See “Reepiratox‘y Physiology”, by John B. West, Lippincott
Williams 85 Wilkins, 9th edition published 2011.
{0004] A range of respiratory disorders exist. Some examples of respiratory
disorders include: etive Sleep Apnea (GSA), Clieyne Stokes Respiration
(CSR), Obesity llyperventilation eme (OHS), Chronic Obetructive Pulmonary
Disease (COPD), Neuromuseular 'Diseaee (NMD) or ehest wall dimmers.
{0005] Otherwise healthy individuals may take advantage of systems and devices.
to prevent respiratory diserders from arising.
WO 48857 2014/050268
1.2.2 Diagnosis and Therapy
{0006] Patients’ interaction with the health system generally comprises two main
stages or phases w a diagnostic stage and a treatment (also referred to as “titer-amt”)
stage
{0007] During the diagnostic stage a patient is tested and the pati.ent"s condition
is diagnosed, In the area of sleep and, respiratory disorders, the diagnostic: providers,
as well as the therapy prr‘ividers can be qualified medical practitioners. also referred to
as physicians or doctors, or assisting practitioners ed to as clinicians. Instead of
conducting a. sleep test in a sleep lap or sleep clinic, a diagnostic providers
increasingly use portable take home g devices to diagnose patients with sleep
disorder breathing. Once the patient is diagnosed, they may he put on a suitable
fhfi‘l‘flpy.
{0008] The ation of the respiratory therapy defines the therapy stage,
during which the patient is treated for the purpose of ng the patient’s condition
and/or ameliorating its symptoms. The services to supply the CPAP s used for
such therapy and r the progreas of the patienfs therapy may be provided by a
therapy provider organisation, such as a Home Medical Equipment (HME) company.
A therapy provider from the therapy provider company such as a therapy clinician,
may configure the device. as per directions from the prescription, and put, the patient
on a program to monitor their ongoing adherence to therapy and the patient’s therapy
progress. For example, patients suffering from sleep apnea may be diagnosed via a
Home. Sleep Test. by a diagnostic provider and prescribed a therapy device, such as a
continuous ve airway pressure ("CPAP") device, for home atory therapy
that, is prescribed to operate at a particular pressure. The therapy provider for this
patient will provide the device and set the required pressure and other settings.
Alternatively, the therapy device may be configured for automatic initial setup, based
on the prescription gs in the diagnostic prescription issued by the diagnostic
provider,
Thus, the therapy provider may be responsible for setting the patient for
therapy. This may e selection of a treatment. mask, humidifier, crmd‘uits and
other accesseries, which may or may not be ied in the iption issued by the
diagnostic prtwider. Apart from the initial setup, the therapy provider will also
WO 48857
monitor the therapy data from the patient therapy sessions. if the t’s y
progress is unsatisfactory or there are other problems with the therapy, the therapy
provider may refer the patient. hack to the diagnostic provider for review and
modification. to the therapy.
{0010] Insrrrance companies. or other assessing or reimbursing entity computer
103., often e evidence that the patient has been diagnosed in an appropriate
manner before paying tor the diagnosis. in order for a determinatirm to be made of
whether a t was appropriately diagnosed, a diagnostic provider will need to
present the appropriate data from a Home Steep Test device {which will also be
referred loin this specification as a diagnostic device) and a diagnosis needs to he
made available that is signed by a qualified ian. Furthermore, insurance
companies often want to track whether a patient. once diagnosed with a medical.
condition successfully proceeds to and remains on the therapy for which they are
prescribed. This process can be inefficient and time consuming, with very poor patient
traceahiiity during the er of the patient between the. diagnostic and therapy
provider. The er may he inconvenient and disruptiv :, because multiple records
of the patient (eg. one during the diagnostic stage patient management. and another
one during the therapy stage) are being created on different software es and in
different software environments. The communication between the two stages also
currently involves paper records and/or faxed doc nrnents. This may cause
inconvenience to the patients and the diagnostic and therapy service providers. as well
as cause errors in the patient"s s.
1.2.3 Systems
{0013] A therapy system may comprise a atory Pressure y Device
{RPT device), an. air circuit, a humidifier. a patient i'ntettaee. and data management.
1.2.4 Patient Interface
{0012] A patient interface may be used to interface respiratory equipment to its
user, for example by providing a flow of ahie gas. The flow of breathable gas
may be provided via a mask to the nose and/or month a tube to the month or a
trachoostotny tube to the trachea of the user. Depending upon the therapy to be
applied the patient interface may form a seat. eg. with a face region of the patient, to
facilitate the delivery of gas at .3 pressure at sufficient variance with ambient pressure
to effect therapy. eg. a. positive pressure of about ermHZO. For other forms of
therapy. such as the delivery of oxygen. the patient interface may not include a seal
Sufficient to tate ry to the airways of a supply of gas at a positive pressure
of nbnut lilomH'LZO,
{0013] The design of a patient interface presents a number of challenges. The
face has. a complex threewdimensional shape. The size and shape of noses varies
considerably between duals. Since the head includes" bone. cartilage and soft
tissue. different regions of the face renpond differently to mechanical. forces. The jaw
or mandible may move relative to other bones of the skull. The whole head may more
during the course of a period of respiratory therapy.
As a consequence of theee Challengea Some masks suffer from being one
or more of obtrusive, aesthetically undesirable, costly, poorly fitting. difficult to use
and uncomfortable especially when won} for long periods of time or when a patient is:
unfamiliar with a system. For example, masks designed solely for aviatore, mask
designed as part Of personal protection equipment (eg. filter masks)g SCUBA masks
or for the administration of annerstiieties may he tolerable for their original
application. but nevertheless be undesirably uncomfortable to be worn for extended
periods of time, eg. several hourn This; is even more so if the mask. is to be worn
during sleep.
{0015] Nasal CPAP therapy is highly ive to treat certain respiratory
disordersi provided patients comply with therapy. If a mask is uncomfortable, or
difficult to use a, patient may not comply with y. Since it is often recommended
that a, patient regularly wash their mask, if a mask is difficult to clean (eg. difficult to
le or dieassemble). ts may not. clean their mask and this may . on
t compliance.
{0016] While a mask for other applications (6.3;. aviators) may not. be suitable for
use in treating sleep disordered breathing. a mask ed for use in treating sleep
disordered breathing may be le for other applications.
{0017] For these reasons, masks for delivery of nasal CPA]? during, sleep form a
distinct field.
1.2.4.1 Seal-forming portion
{0018] Patient interfaces may include a seal—forming portion. Since it. is in direct
contact with the patient’s face. the shape and configuration of the seal—forming
portion can have a direct impact the effectiveness and comfort of the patient. interface.
{0019] A patient interface may be partly characterised aecerding to the design
intent of where the seal—ferming n is to engage with the face in use In one form
of patient interface, a seahi‘orniing pnrtion may cemprise two submertions' to engage
with respective left. and right hares. In one fame of patient. interface, a seal—ferming
portion may comprise a. single element that surrounds both name in use. Such single
element may he designed to for example overlay an upper iip region and a ,nzztenl
bridge region {If a face. In tine fem“: of patient. interface a. seaivferming n may
comprise an element that Surrounds a month regien in use, eg. by forming. a seal on a
lower lip .regien of a face. In one farm of patient inter ace, 3. seal—forming poflion may
comprise a, single element that nds both name and a mouth region in use. These
different types of patient aces may be known by a variety of names by their
manufacturer including nasal masks, full-face masks, nasal piliews, nasal puffs and
ore—nasal masks.
{0020] A sealdi‘n‘riiiiig portion that. may be effective in one region of a patient’s
face may be. in appropriate in another region. eg. because of the different Shape,
re. variability and Sensitivity regime of the patient‘s face. For example, 21 Seal
on swimming goggles that overlays a patienfis ferehead may not. be riate to use
on a patient’s nose.
{0021] Certain seal—fanning ne may be designed fer mass cture such
that one design [it and be ernnfoitabie and effective for a wide range of different face
shapes and sizes; To the extent to which there is a ch n the shape (if the
t‘s face, and the seal—forming, portion of the mass—mzsnulfnetured patient
interface-i one {31“ both must adapt in order for a seal to form.
{0022] One type of seal-forming n extends mound the periphery of the
patient interface and is intended to 581211 against the user's face when force is applied
tn the patient interface with the seat-forming portion in confronting engagement with
the user‘s face. The neahi‘orming portion may include an air or. fluid filled cushion, 0r
a moulded or formed surface of a resilient seal element made of an elastomer such as
a rubber. With this type of seal-forming .01}, if the fit is not adequate, there will be
gaps between the seal—forming portion and the face, and additional force will he
required to force the patient interface against the face in order to achieve a seal.
{0023] Another type of seal—forming portion incorporates a flap seal of thin
material so positioned about the periphery of the mask so as to provide a. selfvscaling
action against the face of the user when positive pressure is applied within the mask.
Like the previous style of seal forming n, if the match n the face and the
mask i s not good, additional force may he required to effect a seal, or the mask may
leak. Furthermore, if the shape of the wallowing portion does not match that of the
patient, it may crease or buckle in use, giving rise to leaks.
Another type of seal—forming portion may comprise a friction-fit element,
eg. for insertion into a naris.
{0025] r form, of seal—forming portion may use adhesive to effect a seal.
Some patients may find it. enient to constantly apply and remove an adhesive to
their face.
{0026] A range of patient inteii‘aee orming portion technologies are.
disclosed in the following patent applications, assigned to d Limited: WO
1993004310; ‘NO 2006/0745133VC) 2010M 35.785.
[0027'] One form of nasal pillow is found in the Adam Circuit manufactured by
Puritan Bennett. Another naaal pillow, or nasal puff is the subject of US Patent
4,782,832 (Triniblc et 31.), assigned to Puritan—B ennett Corporation.
{0028] ResMed Limited has manufactured the following products that.

amongst other things aspects. of Rest/led SWIFT FX nasal pillows).
1.2.4.2 Positioning and stabilising
{0029] A seal—forming portion of a patient interface used For positive air pressure
therapy is subject to the ponding force of the air pressure. to disrupt a seal. Thus
a variety of techniques have. been used to position the senhforming n, and to
in it in sealing relation with the appropriate portion of the face.
{0030] Cine technique is the use of adhenivee. See for example U5 Patent
publication US EMU/0000534.
[003i] Another technique is the use of one or more straps and stabilising
harnesses. Many such harnesses suffer from being one or more of tting, bulky,
ortable and awkward to use.
1.2.5 atory Pressure Therapy (RPT) Device
{0032] One known RPT device used for ng Sleep disordered breathing is the
S9 Sleep Therapy System, manufactured by ResMed. Another example of an RPT
device is a ventilator. Ventilators such an. the RenMed t‘3tellanM Series of Adult and
Paediatric Ventilators may provide support for invasive and nominvaaiue new
dependent ation for a range of patients for treating a number of conditions such
as but not limited to NMD.‘ ()HS and COPD. RPT devices have also been known as
flow tors.
Kit 33] The ResMed EliséeTM 150 ventilator and Flesh/ted V5 111"“ ventilator may
e support for invasive and noninvasive dependent ventilation suitable for adult
or paediatric patients for treating a number of conditions. These ventilators provide
volumetric and barometric ventilation. modes with a single or double limb circuit.
RPT devices typically comprise a pressure generator, such as a motor—
driven blower or a compressed gas oir, and are configured to supply a flow of
air to the airway of a patient. In some cases, the flow of air may be supplied to the
airway of the patient at positive pressure. The outlet of the RPT device is connected
via an air circuit to a patient interface such as those described above.
{0035] RPT devices typically also include an inlet filter, various sensors and a
microprocessor-‘based controller. A blower may include a Servo—controlled melon a
voiute and an impeller. In some cases a brake for the motor may be implemented to
more rapidly reduce. the speed of the blower so as to overcome the inertia. of the motor
and impeller. The braking can permit the blower to more rapidly e a lower
’pI‘ESSUYG condition in time for synchronization with expiration despite the inertia. in
some cases the pressure generator may also include a valve capable of dischm‘ging
generated air to atmosphere as a means for altering the re delivered to the
patient as an alternative to motor speed control. The senders measure, amongst other
things, motor speed, mass flow rate and outlet pressure, such as with a pressure
transducer or the like. The controller may e data storage capacity with or
without integrated data retrieval and display functions.

1.2.6 Humidifier
{0037] ry of a flow of breathable gas t ficatlon may cause
drying of s. Medical humidifiers are used to increase humidity andlor
temperature of the flow of able gas in relation to ambient air when required:
typically where the patient. may be aaleep or renting leg. at a hospital). As a result, a
medical humidifier is preferably small for bedaide placement, and it is preferably
configured to only humidify andfor heat the flow of breathable gas delivered to the
patient without humidifying andfor g the patient’s surroundings. Room—based
systems tag a sauna, an air ioner, an evaporalive cooler), for example, may
also humidity air that is ed in h}; the patient, however they would also humidity
andjor heat the entire room which may cause discomfort. to the occupants.
{0038] The one of a humidifier with a flow generator or RPT device and the patient
interface produces humidified gas that minimizes drying of the nasal mucosa and
increases patient: airway comfort. 1an addition, in cooler climates warm air applied
generally to the face area. in and about the patient interface is more comfortable than
cold air.
{0039] Respiratory humidifiers are available in many forms and may he a standalone
device that is coupled to a respiratory apparatus via an air circuit, is integrated with or
configured to be coupled to the relevant respiratory apparatus. While known passive
humidifiers can provide some relief, lly a heated humidifier may be used to
provide sufficient humidity and temperature to the air so that, the patient will be
comfortable. Humidifiers typically comprise a water reservoir or tub having a
capacity of l hundred milliliters (1111), a g element for heating the water in
the reservoir, :1 control to enable the level of humidificutiou to be varied, a gas inlet to
receive gas from the. flow tor or RPT device and a gas outlet, adapted to be
connected to an air circuit that: rs the humidified gas to the patient interface.
{0040] Heated passover humidification is one common form of hurnidification
used with a RPT device. In such fiers the heating t may be incorporated
in a heater plate which sits under, and is in thermal contact with, the water tub. Thus,
heat is transferred from the healer plate to the water reservoir primarily by
conduction. The air flow from the EFT device passes over the heated water in the
water tub resulting in water vapour being taken up by the air flow. The ResMed
H4?“ and FliiiTM Humidifiers are examples of such heated passover humidifiers that
are used in combination, with ResMed SS and S9 CPAP devices respectively.
{DOM} r humidifiers may also he used such as a bubble or diffuser
humidifier, a jet humidifier or a Melting humidifier. In a bubble or er humidifier
the '
z ' is ted below the surface of the water and allowed to bubble back to the
top. A jet humidifier produces an aerosol of water and baffles or filters may be used
so that the particles are either removed or evaporated before leaving the fier,
A wire-hing humidifier uses a water absorbing material, such as sponge or: paper, to
2014/050268
absorb water by capillary action. The writer absorbing material, is placed within or
adjacent at least a portion of the air flow path to allow evaporation of the water in the
absorbing material to be taken up into the air flow.
{0042] An alternative form of humidifieatinn is presided by the ResMed
HumiCare‘l‘M 13900 humidifier that uses a {InunterStresm‘l‘M logy that directs
the air flow over a large surface area in at first direction whilst ing heated water
to the large surface area in a second opposite direction. The ResMed HumiCaiel'M
D900 humidifier may be used with a range of invasive and vasive ventilators.

46 EXAMPLE METHODS
{0169] In order for a patient to undergo a test, the patient may need to he issued
with a diagnostic order by the patient‘s treating physician. The patient is referred to a
sleep test where the patient may be issued a diagnostic device 101 for sleep testing.
The diagnoatie device 101 may eoiieet any one of the ing types of data
Poiysomnography (PEG) data? polygraphy data, oximen‘y data pneumatic or
Respiratory Inductance Plethysmography (RIP)-based respiratory effort data,
respiratory flow data, audio signal data, body position data etc.
{01?0] The patient’s record is first created, during the diagnostic stage, when the
patient is approved for running a diagnostic test. The. patient’s record may comprise
any data that is associated. with the patient or with the patient’s condition, such as the
patient’s personal details (name, , age, s, contact details etc), symptoms,
treating physician, nce provider; type of insurance cover etc. From diagnostic
provider‘s er 104, where the patient’s record is created, it is en‘ed to the
ECO database of server 20]. It should be iated that computer 104 may not be a
personal eomputen but. an administration computer used at the diagnostic er
clinie As such, this computer may be ed, at least partially, not by the specific
diagnostie physician responsible for the g and diagnosis of the respective patient.
but by a data administrator on the site. For example, it can, be envisaged that such an
administrator may be responsible for creating the patient’s record,
{0171] During the actuai test, the diagnoatie device collects diagnostic data
indicating any respiratory condition that the patient may have, as well as other
information, such as the type and model of the diagnostic device; the patient’s details?
including these of the referring diagnostic physieinni time and dates of usage etc.
{0172] During the actual test, the diagnestic device saves the diagnostic test data
111 in memory 112,. A 11am of system 100, such as a user of diagnostic provider
er 104, may have a remote access to the merncry 112 of the medical diagnestie
device 101. Alternatively, user of diagnostic prdvider computer 184 may extract, the
portehie memory card of device 101 and ad the data to computer .104. An
addition, one can connect the device 101, eg. via a USB cable, to the diagnostic
provider computer 1041- to access the device memory 112.. A web browser 1131 en the
diagucstic provider cemputer 104 may then he used to contact. server 2131. and upiead
diagnestic data 111 to (me or more of the databases 2'31. 2.32, 233 and 235.
The diagntistic date 111 ed to server 201 frem diagnostic device
101 may be stored in. 21 CAL se 2325 which may fy the type of patient
device from which it. came. Fer example, each diagnostic device 101 may be assigned
a device 11), which is previded tn server 201 along with the diagnostic date. The
diagnostic data may then be stored by server 201 in a database that uses the device 1])
to associate the receii." ed data with. the appropriate patient diagnostic: device 101. The
usage data from therapy device 105 may be processed in a, similar manner.
{0174] In some ces: a patient is required to use a medical diagnostic device
fer a set duratidn and exhibit, certain al symptoms in order to be eligible to
qualify for therapy of the petienti's sleep disnrder ing. For example, a patient
who has been ordered a heme sleep test may be required to use the diagnostic device
for at least four hours and exhibit an Apnea—Hypopnen Index (AHI) of greater than 5
in order for a physician to write a prescription for CPA]? therapy. The prescription
(also referred to as prescription data. or iptien information) may be saved in the
HST database 235'). System 10G may he used to track whether the patient. has been
compliant in using the diagnostic device and may assist a physician in making a
diagnosis.
{0175] Once- the patient is ; a. diagnosis may he issued by the sleep provider
and may be based on the stic infnmratien produced by system 100, and more
specificaliy by the testingfdiagnostic device it) .1. Depending. en the patientris
sis, :1 stic provider, and more specifically a diagnostic physician, may
issue a prescription for therapy. The diagnostic provider may input his or her clinica‘t
interpretation of diagnostic data into the patients record. In addition, the. ECO
database may contain a list of clinical. options for a number of therapy devices 105
which the dingncstic physician may assign in a patient as they see appropriate. In
assigning these devices, ECU server 250 may select the nppreprinte pie—set of gs
from the ECO database and then allow the diagnostic provider to input the clinical
values into the riate fields. The data crn‘respont‘ling tn the patient and device
type may then be stored on server 20] . such as in the ECG database 233.
{0176] In some cases. the testing compliance criteria is usually defined by the
reimbursing authority and may he set in the system 100 by a. user, such as the sleep
physician or clinician in the diagnostic site (in user of diagnostic computer HM). For
e, usage data from diagnostic device 101 may demonstrate that. a. patient was
tested for at. least 4 hours and had an Obstructive Sleep Apnea with an AHE of '20, and
therefore may be a candidate fer CPAP therapy. A qualified fheeithcere professional,
such as a sleep physician, may use ccntpnter 1.04 to write a prescription within a web
r 1‘31 for therapy for a CPA? device at a, pres sure of 14CDIH2Q Dingnnstic
computer 104 may transmit the prescription data to server 201, wherein it will be
stored in a database, such as in. the ECU se 233, to become a part of the
t’s recnrd.
Patients prescribed for therapy will need to ripen new records with their
diagnostic cr, eg. on diagnostic cnmputcr 1.04. Instead, the proposed system
chews access to their record: including any usage and settings (latter, to a therapy
provider computer 102 so that the patients can be supplied and set up with a therapy
device. For example the patient diagnosed with Obstructive Steep Apnea wit] need
to have their patient information and prescription sent to an ed therapy provider
who can supply them with a CPAP device. System 100 may be used to facilitate the
assignment, accesa and er of data from the diagnostic provider to a d
therapy er. Instead cf creating a new t record, the patient’s reccrd may be
electronically transferred. Furthermore instead cf transferring the patient record, the
system may allow the therapy provider to access the present pntient record, as created
and updated during the. diagnostic stage. Depending on the arrangement, the therapy
(a: U]
er may he allowed access either to the entire patient record. or only to some of
the t identification data. stic data. diagnostic report. therapy prescription
and initial device g data. Also. the access to the respective data may be open
access with full. functionality. or only limited . Such a limited access. for
example. may involve the capability to View and/or download the diagnostic data, but
not to modify it.
{0178] The therapy provider may he allowed to modify the access of the
diagnostic provider: For example, after the record is made accessible to the therapy
pmvider. the therapy provider may allow continuous access by the diagnostic provider
to the patient’s record. Depending on the arrangement, the diagnostic provider may
be allowed access either to the entire patient record. or only to some of the patient
data, such as the fs identification data. diagnostic date, but not to the t’s
therapy data. Also. the access to the respective data may he open access with full
functionality, or only limited access. Such, a limited access, for e, may involve
the capability to View andjor download the therapy data, but not to modify it.
{0179] Thus. once the electronic patient record is created, medical practitioners
associated with either the diagnostic stage or the therapy stage may he provided
various level of access to the electronic patient record during both the diagnostic stage
and the therapy stage.
{0180] A health care professional at, a diagnostic provider location, may monitor
the status of their patient’ 5 diagnostics data and formed their iption to a therapy
provider by contacting server 201 Via. a website accessed on stic computer 104.
For example, the healthcare professional may access patient data via webpage 800
tthe oard‘) shown in Fig. 8. Webpage 800 may n a list of active ts
who are cunfently proceeding through home sleep testing. including status- tors
that indicate the status of the patients diagnostic tests. The variOus icons indicate the
different status of the patient. For example — the bed-like icons indicate that the
patient. is stiil in testing phase. The physician profiledike icon indicates that the
patient. has moved to the diagnostic report phase. Different colour. for example. may
he used to, indicate whether the report has or has not being iswed yet. Similarly, the
Rat icon indicates that the pa‘tient’s diagnostic report is ready and the patient has
moved to the prescription stage. Again, different colour may he used to indicate
WO 48857
whether the prescription has or has not being issued yet. Finally, icon 87] may
indicate that the patient is in the “patient record lining finalised" phase.
{0181] As shown in Fig. 9: the patient Noemy Berber has ted her testing,
diagnostic report and prescriptions . The ieen Rn indicates that Noemy’s
diagnostic report and prescription are ready. As indicated by status indicatnr 87; the
pntient’s record has undergone. even the finai cheeks and is now ready to be sent.
Such final. checks may involve verification of the patient’s name, phone number and
nce previder details.
{0182] Once a diagnostic provider associated with diagnostic computer 104 has
determined that the patient needs to go onto therapy the diagnostic provider may
elicit on. the icon 87]. As shown in Fig. 9,. pop—up window 973 may appear when icon
871 is selected. Pop—up window 973 may then be used to send patient information to a
selected therapy provider that is to he as sociated with the therapy of the patient. The
diagnostic provider may select a. particular therapy prnvider from it list of y
providers using own menu 974. For that purpose the diagnestie provider
computer 104 may send a transmission to the ECG server requesting data for
a‘rniinble therapy ers within. the system of therapy providers. ECO server will
then provide data responsive to the request; which will populate menu 974 within the
web hrewser 131. By clicking on send hutten 976 the healtheare professional can
instantly confirm their Choice and initiate a cnniniand to, the ECU server to transfer
hip of the patient record to the therapy provider nominated in menu 974.
Clicking on send button 976 transfers ownership of the patient: to the thernpy provider
and changes the status of the patient within the dashboard tn "Resuits Sent." in this
way, heuitheare pi‘t‘ifessionnls may quickly and easily transfer their patients directly
into the therapy provider’s in‘hox without having to manually transfer paper reenrde
viz-1 fax, mail, or via the patient
In some instances. ECO server 250 may automatically previde thempy
provider coniputer .102, by way of. web browser (eg. instmetimis 130) and via the
network 150. with the usage and therapy settings data required to set. up a; patient on
y device 105 as threaten by the diagnostic er physician‘s iption. For
e a therapy previder may he notified by the ECG server 250 when a diagnosis
and prescription for y has been created on the server by n diagnostics provider
and assigned to them. This allows the therapy provider to be immediately informed of
a. patient’s er into their care and ensuree that a patient is supplied with the
correct therapy device having the required therapeutic settings... The settings data. can
be automatically transferred directly to therapy device 105, each as via an internet
connection, or manually ed via an SD card or the therapy device’s. interface.
{0184] A therapy provider may be automatically alerted that a patient has been
referred to them by messaging service, such as Email or SMS messaging, or by
contacting therapy er computer 192 via server 201. For example, the therapy
provider or an administrator at the therapy provider” 3 office may aceea 3 th ‘
transferred patient information described above via wehpage 900 shown in Fig. 10.
W’ehpage 900 may contain s data items, such as patient names 970: referring
diagnostic providers 982,. contact: details 933, diagnostic and prescription. information
984, insurer data. 986. an acceptance Status 987,. or any other patient information of
intereat. A therapy provider may use wehpage 900 to accept or reject a patient.
referral. For example, the therapy provider may select a patient having an
”accept/reject” Status, and then deaignate the ts al as either "accepted" or
"rejected" Once the therapy provider has accepted the desired patient, the therapy
provider computer 102 may send a transmission to the ECG server requesting
additional t health intonnatilon from the ECU database for the relevant patient
ID. ECO server will then provide patient. demographi : and therapy settings data
responsive to the request... which once available will be used to fire—populate data.
fields required for a Setup of the new patient with a therapy . Thus, the system
is ured to dynamically update the therapy provider‘s available patient list the
record of the new patient, as well as to start displaying the additional. patient. record in
the patient list of the therapy provider. For example, Fig. 11 shows webpage 910 in
which the t Noemy Harbor may be automatically assigned s therapy
s in accordance with her prescription. The healthcare professional. may alter
the aasigned devices or identify additional therapy s or components infield
1102. and have those devices or ents assigned to the patient by selecting the
Add icon l .164.
{0185] As shown in Fig. it), Noenty Barber’s patient. record details are now
visible to the administrative staff using therapy er computer 1(i2. After
contacting the patient. such an by the website. email, or phone, the administrator may

administrator may click on Accept and use dialogue box. 985 to assign the t to a
clinical user and transfer the new patient into the therapy provider” s work queue. The
therapy er’s work queue is Shown in Fig. 12 as webpage 9:20. The work queue
wehpnge may Show compliance icons 1202 and noncompliance icons 1204 to indicate
r a patient. is currently compliant with his or her prescribed therapy. The work
queue may also indicate the last time the compliance data was updated, as Welt as
tics regarding the patients usage of the therapy device. The work queue of
webpage 920 may be securely accessed by a ciinic.ian,. an administrator, or both.
Secure access may include some form of' protection to prevent unauthorized
individuals from access patient data. F01“ example. Server 201 of Fig. 7 may require a
password before transmitting patient. data. Server 20} may also encrypt: the
transmitted data so as to prevent unauthorized devices from displaying the data.
{0186] A healthcare professional may also assign and configure Noemy Heather’s
therapy device via webpage 920 shown in Fig. 12, and set her up for ongoing,
monitoring by clicking on her name and opening the patient record shown in Fig. 13
as wehpage 9‘30. As seen on wehpage 930 within the patient record n, the
patient information required to set up a patient for ongoing monitoring may be already
pro-populated from the ECO database 233 with any patient data. available from the
diagnostic provider including patient demographics, nce ation and device
therapy settinge. As described above, a. prescribed CPAP therapy device with a.
ficntion unit is may be automatically aSsigned to the patient. In this way,
healthcnre professionals may quickly and easily set up patients on y without
having to re—enter the patient: data manually from paper prescriptions as well as
reducing the percentage of patient who fail to present at the therapy provider for
y. All therapy note-s, prescriptions, and diagnostic reports may be viewed
within the notes section of the t record as shown in webpage £140 of Fig. 14.
{0.1 $7] Returning to Fig. 7, a therapy healthcnre pretensional who accesses eerver
]. Via therapy provider computer 1‘32 may provide diagnostic; and compliance
y s. which. bewe been generated by server 201, to the respective
assessing entities. This can be performed, by transmitting the diagnostic and/or
compliance reports from. therapy prttwider computer 102 to an external party, such as
the reimbursing entity computer 163, via network 150. The diagnostic andfor
ance reports may be transmitted in any number of ways. including as part of an
Email transmis sinn. Alternatively, the cliagnnstic andfor compliance reports may be
saved either at therapy provider computer 102 or server 201 and the assessing entity
may send, via the reimbursing entity computer KB, a request for diagnostic andjor
compliance reports to either computer 102 or sewer 201.
{0188] Fig. 15 provides a schematic representation for the system and methods
described above. As seen, in Fig. 15? a single t record may he created, saved to
a single data platform! d and acces and by using a single settwarc system,
regardless of whether the t is the diagnostic or the therapy stage of the t
management. In addition, the data platform may reside on multiple remote servers or
en a. single physical system of servers so as to allow for integrated electronic
management of data relating to both the diagnnstic stage and therapy stage. Medical
practitioners from both the diagnostic management stage and the therapy management
stage may be provided access to this record and can save and access relevant data
associated with at least one of general patient data, diagnostic data, device usage data,
compliance data, device parameters, diagnostic report, device prescription etc. This
reduces the time and effort involved in creating multiple records, as well as minimises
the likelihood of errors The described system has the following es:
The capability to ad to, upload from. View anti analyse diagnostic
data within the same software management: tools and, in, some cases, physical set of
servers as the therapy management; stage data. This makes it much more convenient
for both the diagnostic providers and the therapy providers, as they have a single point
of access to the patient’s data and do not need to use two different data platforms,
have two different passwords etc. Here the term data platform is used broadly in
relation to at least one of the hardware setup and the used software. The service
previtlers front the reimbursement entity 1633 also need to access both the stic
and the therapy data {if the patient to evaluate r the patient is ant with
the prescribed diagnostic or y requirements. Thus, they also benefit from the
single password, the single point of entry and the use of a single data rm used
for accessing both types of data.
{0190] The capability to upload diagnostic data, diagnostic reports, prescription
information. as well as a therapy device usage and compliance data, directly into the
original patient’s therapy record d mid populated in the. diagnostics data
management stage.
{0193] The capability to send device settings data from, a prescription issued by a
sleep ian ly to the diagnostic patient reenrd, where it can be accessed and
downloaded by the therapy provider without the need of manual rewriting or
onic recreating of the record. This contrasts with the current practice of the
patient having to personally take their prescription to the therapy er or, at best.
the diagnostic provider faxing or otherwise transfening the prescription to the therapy
provider who then has to read the prescription and manually input the settings into the
device. The proposed system allnws the diagnostic provider to save the prescription in
the patient record from where it is directly accessed by the therapy provider. Those
gs can also he automatically downloaded to a card or sent. wirelessly to the
device upon device setup.
