Abstract

A system and method for remotely monitoring a patient and for training the patient to comply with a treatment plan for a health condition. A patient computing device (320) collects data relating to the patient's health condition and transmits the data to a clinician computer (200) via a communication network (280). The data is analyzed in the clinician computer to determine an educational need of the patient for treating the health condition. An educational program corresponding to the patient's educational need is selected and a pointer to the educational program is embedded in an electronic message to the patient. The educational program (360) is started on the patient computing device by selecting the embedded pointer in the electronic message. As the patient works with the educational program, new data relating to the patient's health condition is collected in the patient computing device and transmitted to the clinician computer for analysis. With this continuous feedback loop between the patient and clinician, the clinician is able to monitor the patient's progress and effectively train the patient to comply with the treatment plan.

HEALTH MANAGEMENT PROCESS CONTROL SYSTEM

BACKGROUND -- FIELD OF THE INVENTION The present invention relates to the field of health management, and in particular to a system and method for remotely monitoring a patient and for training the patient to comply with a treatment plan for a health condition.

BACKGROUND -- DESCRIPTION OF PRIOR ART In recent years, an increasing number of healthcare providers have initiated outpatient or home healthcare programs for their patients. The potential benefits of these home healthcare programs are particularly good for chronically ill patients, such as those suffering from asthma or diabetes, who must treat their diseases on a daily basis. However, the success of these home healthcare programs is currently limited by the ability of healthcare providers to assess, monitor and train patients to comply with treatment plans for their health conditions.

Many systems have been developed for remotely monitoring a patient's compliance with a prescribed medication plan. For example, U.S. Patent 5,390,238 issued to Kirk et al . on February 14, 1995 discloses a home healthcare and communication support system. The system includes a health support unit located in the patient's home for monitoring and supporting a patient. The health support unit is networked to a remote monitoring terminal for continuous remote monitoring of the patient. The health support unit includes a medication controller for measuring the patient's medicine compliance and a communications module for communicating with an operator at the monitoring terminal. The health support is further networked to the patient's healthcare provider to allow the healthcare provider access to the patient's medicine compliance data. A similar system for monitoring a patient's medicine compliance is described in U.S. Patent 5,016,172 issued to Dessertine on May 14, 1991. The system includes an automatic medicine compliance monitoring device for measuring the patient's actual medicine consumption. The monitoring device is connected to a patient computing device for recording the patient's medicine consumption. The patient computing device is further connected to a remote monitoring terminal for displaying the patient's medicine compliance to a healthcare provider. The system optionally includes a second monitoring device for monitoring a physical condition of the patient, such as heart rate, blood pressure, blood glucose, or respiration.

Although the systems described by Kirk and Dessertine allow remote monitoring of a patient's health condition and medicine compliance, they have no mechanism for ensuring patient compliance with a treatment plan. Further, these systems are not directed at providing the patient guidelines for treating a health condition. They are simply designed to monitor the patient from a remote location.

Numerous systems have also been developed for prompting a patient take prescribed doses of medication in addition to remotely monitoring the patient's health condition. For example, U.S. Patent 5,501,231 issued to Kaish on March 26, 1996 describes a patient-operated, hand-held system for testing and recording peak flow rates of an asthma patient. The system includes a peak flow meter for measuring the patient's peak flow rates and an alarm for prompting the patient to take a prescribed dose of medication. In using the system, the patient records his or her peak flow rates over a predetermined period of time, typically fifteen days to six months, before returning the system to a doctor for recovery of the peak flow data. At this time, the doctor may optionally reprogram the system with new alarm times and prescribed medicine doses.

Although the system described by Kaish has the advantage of prompting a patient to take medication, it lacks any mechanism for training the patient to actually comply with the prompts. The system is limited to issuing preprogrammed medicine instructions to the patient without teaching the patient why or how to follow the instructions. Further, the system cannot identify any problems the patient is experiencing in following a treatment plan for his or her health condition or teach the patient how to solve the problems. As a result, the patient may not be able to comply with the prescribed treatment plan, severely limiting the effectiveness of this home healthcare system. Additionally, the system described by Kaish does not permit continuous feedback between the doctor and patient for ongoing adjustment of the treatment plan.

Another system for remotely monitoring a patient and for prompting a patient to take a prescribed dose of medication is disclosed in U.S, Patent 4,731,726 issued to Allen on March 15, 1988. Allen describes a diabetes management system having a blood glucose meter for measuring a patient ' s blood glucose levels and for sending the blood glucose measurements to a physician. The system further includes a user interface for entering in the system data relating to the patient's medication usage, exercise routine, and dietary intake. Based on the entered data, the system calculates a recommended insulin dose for the patient using a physician prescribed algorithm stored in its memory.

Allen's system suffers from the same disadvantage as Kaish' s system in failing to train the patient to comply with the prescribed treatment plan. The system is limited to issuing dosage instructions based on a preprogrammed algorithm without identifying any problems the patient is experiencing with the diabetes program or teaching the patient how to solve the problems. Consequently, the effectiveness of this diabetes management system is also limited.

A similar system for home management of diabetes is disclosed in U.S. Patent 5,109,974 issued to Beckers on May 28, 1991. The system includes a physician computer for developing a diabetes therapy program and a patient recorder having an interface for exchanging data with the physician computer. The recorder has a blood glucose test strip for measuring the patient ' s blood glucose levels and a user interface for entering in the recorder data relating to the patient's insulin usage, exercise routines, and dietary intake. Using the patient data and therapy guidelines downloaded from the physician computer, the recorder calculates and displays to the patient a recommended insulin dosage, exercise plan, and diet. The recorder also receives from the physician computer new therapy guidelines developed from the patient's recorded data .

Although the diabetes management program disclosed by Beckers has the advantage of adjusting a patient's recommended therapy program based on remote monitoring of the patient, it also has the same disadvantage as the previous systems in failing to teach the patient how to follow the prescribed treatment plan. Becker's system has no mechanism for identifying problems the patient is experiencing with the diabetes program or for teaching the patient how to solve the problems. As a result, Becker's system is also ineffective for training the patient to comply with the diabetes treatment plan.

OBJECTS AND ADVANTAGES OF THE INVENTION In view of the above, it is an object of the present invention to provide a system and method for remotely monitoring a patient and for effectively training the patient to comply with a treatment plan for a health condition. It is another object of the invention to provide a method for teaching a patient to solve a specific problem the patient is experiencing with a treatment plan. A further object of the invention is to provide a system that allows continuous feedback between a clinician and patient for ongoing adjustment of a treatment plan.

The invention provides a new and useful system for healthcare monitoring and patient training based on a small microprocessor- based unit or a personal computer which is networked with the clinician's resources and requisite databases.

These and other objects and advantages will become more apparent after consideration of the ensuing description and the accompanying drawings . SUMMARY OF THE INVENTION The invention presents a system and method for remotely monitoring a patient and for training the patient to comply with a treatment plan for a health condition. The system includes a patient computing device, such as a personal computer or network terminal, for collecting data relating to the health condition. In the preferred embodiment, the data includes measurements of a physical characteristic of the health condition, such as blood glucose measurements for a diabetic patient or peak flow measurements for an asthmatic patient. Also in the preferred embodiment, the data includes measurements of a psychological characteristic of the health condition, such as the patient's knowledge, comprehension, or attitude in treating the health condition.

The system further includes a clinician computer having a data analysis program for analyzing the data to determine an educational need of the patient. The clinician computer also has a message program, such as an electronic mail program, for composing an electronic message to the patient. The electronic message contains a pointer to an educational program corresponding to the patient's educational need. The pointer is a prompt embedded in the message. When the patient selects the pointer the latter loads and executes the educational program instructions linked to the message. A communication network connects the patient computing device and the clinician computer and transmits the data and the electronic message therebetween.

A preferred method of using the system includes the steps of entering data relating to the patient's health condition into the patient computing device and transmitting the data from the patient computing device to the clinician computer via the communication network. The method further includes the steps of analyzing the data received in the clinician computer to determine an educational need of the patient and selecting an educational program corresponding to the educational need. A pointer to the selected educational program is then embedded in an electronic message to the patient. The electronic message is transmitted through the communication network from the clinician computer to the patient computing device.

The educational program is started on the patient computing device when the patient selects the embedded pointer in the electronic message. As the patient works with the educational program, new data relating to the patient's health condition is collected in the patient computing device and transmitted to the clinician computer for analysis. With this continuos feedback loop between the patient and clinician, the clinician is able to monitor the patient ' s progress and effectively train the patient to comply with the treatment plan.

DESCRIPTION

FIG. 1A depicts a self-care health monitoring system arranged in accordance with the invention. In the arrangement shown in FIG. 1A, a data management unit 10 is electrically interconnected with a computing device such as a computer or a handheld microprocessor-based unit 12 via a cable 14. In the depicted arrangement, data management unit 10 also is electrically interconnected with a blood glucose monitor 16 of the type capable of sensing blood glucose level and producing an electrical signal representative thereof.

Although FIG. 1A illustrates blood glucose monitor 16 as being connected to data management unit 10 by a cable 18, it may be preferable to construct blood glucose monitor 16 as a plug-in unit that is placed in a recess or other suitable opening or slot in data management unit 10.

Also shown in FIG. 1A are two additional monitoring devices 20 and 22, which are electrically connected for serial data communication with data management unit 10 via cables 24 and 26, respectively. Monitoring units 20 and 22 of FIG. 1A represent devices other than blood glucose monitor 16 that can be used to configure the invention for self-care health monitoring applications other than (or in addition to) diabetes care. For example, as is indicated in FIG. 1A, the monitoring device 20 can be a peak-flow meter that provides a digital signal representative of the airflow that results when a person suffering from asthma or another chronic respiratory affliction expels a breath of air through the meter. As is indicated by monitor 22 various other devices can be provided for monitoring conditions such as blood pressure, pulse, and body temperature to thereby realize systems for self-care monitoring and control of conditions such as hypertension, certain heart conditions and various other afflictions and physical conditions. Upon understanding the hereinafter discussed aspects and features of the invention it will be recognized that the invention is easily implemented for these and other types of healthcare monitoring.

As is shown in FIG. 1A, handheld microprocessor unit 12 includes a display screen 28 and a plurality of switches or keys (30, 32, 34, 36, and 38), which are mounted on a housing 40. Located in the interior of housing 40, but not shown in FIG. 1A, are a microprocessor, memory circuits, and circuitry that interfaces switches 30, 32, 34, 36 and 38 with the microprocessor.

Stored in the memory of program microprocessor unit 12 is a set of program instructions that establishes a data protocol that allows microprocessor unit 12 to perform digital data signal processing and generate desired data or graphics for display on display unit 28 when a program cartridge 42 is inserted in a slot or other receptacle in housing 40. That is, program cartridge 42 includes read-only memory units (or other memory means such as battery- powered random access memory) which store program instructions and data that adapt handheld microprocessor 12 for operation in a blood glucose monitoring system. More specifically, when the instructions and data of program cartridge 42 are combined with program instructions and data included in the internal memory circuits of microprocessor unit 12, microprocessor unit 12 is programmed for processing and displaying blood glucose information in the manner described below and additional monitors 22 to provide health monitoring for asthma and various other previously mentioned chronic conditions. In each case, the plurality of switches or keys 30, 32, 34, 36, and 38 are selectively operated to provide signals that result in pictorial and/or alphanumeric information being displayed by display unit 42.

Various devices are known that meet the above-set forth description of microprocessor unit 12. For example, compact devices are available in which the plurality of keys allows alphanumeric entry and internal memory is provided for storing information such as names, addresses, phone numbers, and an appointment calendar. Small program cartridges or cards can be inserted in these devices to program the device for various purposes such as the playing of games. More recently, less compact products that have more extensive computational capability and are generally called "palm top computers" have been introduced into the marketplace. These devices also can include provision for programming the device by means of an insertable program card or cartridge. Alternatively, the program can be loaded into their memory from a network or via a modem connection. A person of average skill in the art will appreciate that there exist other suitable methods for loading programs into suitable computer devices.

Another advantage of realizing handheld microprocessor unit 12 in the form of a compact video game system is the relatively simple, yet versatile arrangement of switches that is provided by such a device. For example, a compact video game system includes a control pad 30 that allows an object displayed on display unit 42 to be moved in a selected direction (i.e., up-down or left-right). As also is indicated in FIG. 1A, compact video game systems typically provide two pair of distinctly-shaped push button switches. A pair of spaced-apart circular push button switches

(36 and 38) and a pair of elongate switches (32 and 34) are provided. The functions performed by the two pairs of switches is dependent upon the program instructions contained in each program cartridge 42.

Yet another advantage of utilizing a compact video game system for handheld microprocessor-based unit 12 of FIG. 1A is the widespread popularity and low cost of such units. In this regard, manufacture and sale of a data management unit 10, blood glucose monitor 16 and program cartridge 42 that operate in conjunction with a compact microprocessor-based video allows the self-care health monitoring system of FIG. lA to be manufactured and sold at a lower cost than could be realized in an arrangement in which handheld unit 12 is designed and manufactured solely for use in the system.

An even further advantage of using a compact video game system for handheld microprocessor 12 is that such video game systems include means for easily establishing the electrical interconnection provided by cable 14. In particular, such compact video game systems include a connector 40 mounted to the game unit housing and a cable that can be connected between the connectors of two video game units to allow interactive operation of the two interconnected units (i.e., to allow contemporaneous game play by two players or competition between players as they individually play identical but separate games) . The cable supplied with handheld microprocessor unit 12 can be used as cable 14 to establish serial data communication between the handheld microprocessor unit 12 (compact video game system) and data management unit 10.

Depending upon the operational mode selected by the user, data is supplied to data management unit 10 by blood glucose monitor 16, by additional monitors (20 and 22 in FIG. 1A) or any interconnected computers or data processing facility (such as the hereinafter described user's computer 48 and clearinghouse 54). During such operation, mode switches 30, 32, 34, 36 and 38 are selectively activated so that signals are selectively coupled to microprocessor unit 12 and processed in accordance with program instructions stored in program cartridge 42. The signal processing performed by microprocessor unit 12 results in the display of alphanumeric, symbolic, or graphic information on the video game display 28, which allow the user to control system operation and obtain desired test results and other information.

Although the above-discussed advantages apply to use of the invention by all age groups, employing a compact video game system in the practice of the invention is of special significance in monitoring a child's blood glucose or other health parameters. Children and young adults are familiar with compact video game systems. Thus, children will accept a health monitoring system incorporating a compact video game system more readily than a traditional system, even an embodiment of the invention that uses a different type of handheld microprocessor unit. Moreover, an embodiment of the invention that functions in conjunction with a compact video game system can be arranged to motivate children to monitor themselves more closely than they might otherwise by incorporating game-like features and/or animation in system instruction and test result displays. Similarly, the program instructions can be included in program cartridges 41, 42 and 43 (or additional cartridges) that allow children to select game-like displays that help educate the child about his or her condition and the need for monitoring.

With continued reference to FIG. 1A, data management unit 10 includes a data port 44 that allows communication between data management unit 10 and a personal computer 48 (or other programmable data processor) . Data port 44 is, for example, an RS-232 connection that allows serial data communication between data management unit 10 and personal computer 48. In the practice of the invention, personal computer 48 can be used to supplement data management unit 10 by, for example, performing more complex analyses of blood glucose and other data that has been supplied to and stored in the memory circuits of data management unit 10. With respect to embodiments of the invention configured for use by a child, personal computer 48 can be used by a parent or guardian to review and analyze the child's progress and to produce printed records for subsequent review by a healthcare professional.

Alternatively, personal computer 48 can be used to supply data to data management unit 10 that is not conveniently supplied by using handheld microprocessor switches 30, 32, 34, 36 and 38 as an operator interface to the system of FIG. 1A. For example, some embodiments of the invention may employ a substantial amount of alphanumeric information that must be entered by the system user. Although it is possible to enter such data by using switches 30, 32, 34, 36 and 38 in conjunction with menus and selection screens displayed on display screen 28 of FIG. 1A, it may be more advantageous to use a device such as personal computer 48 for entry of such data. However, if personal computer 48 is used in this manner, some trade-off of system features may be required because data management unit 10 must be temporarily interconnected with personal computer 48 during these operations. That is, some loss of system mobility might result because a suitably programmed personal computer would be needed at each location at which data entry or analysis is to occur. Of course, it will be recognized by a person of average skill in the art that in certain embodiments personal computer 48 can absorb the entire functionality of unit 12 and data management unit 10. A system based on computer 48 only may be more successful with adult patients or when the data to be displayed is very complicated and requires the entire computer screen.

As is indicated in FIG. 1A, data management unit 10 of the currently preferred embodiments of the invention also includes a modem that allows data communication between data management unit 10 and an information service, computing facility or clearinghouse 54 via a conventional telephone line 50 in and a modem 52 that interconnects clearinghouse 54 via telephone line 50.

Clearinghouse 54 facilitates communication between a user of the system and his or her healthcare professional and can provide additional services such as updating system software or downloading specific programs to the user. In fact, in one embodiment clearing house 54 is the computer used by the clinician. As is indicated by facsimile machine 55 of FIG. 1A, a primary function of clearinghouse 54 is providing the healthcare professional with standardized reports 56, which indicate both the current condition and condition trends of the system user. Although a single facsimile machine 55 is shown in FIG. 1A, it will be recognized that numerous healthcare professionals (and hence facsimile machine 55) can be connected in signal communication with a clearinghouse 54. In this situation each healthcare professional may have his or her own clinician computer linked to clearinghouse 54 according to methods well known in the art.

Regardless of whether a compact video game system, another type of commercially available handheld microprocessor-based unit, or a specially designed unit is used, the system of FIG. lA provides a self-care blood glucose monitoring system in which program cartridge 42: (a) adapts handheld microprocessor unit 12 for displaying instructions for performing the blood glucose test sequence and associated calibration and test procedures; (b) adapts handheld microprocessor unit 12 for displaying (graphically or alphanumerically) statistical data such as blood glucose test results taken during a specific period of time (e.g., a day, week, etc.); (c) adapts handheld microprocessor unit 12 for supplying control signals and signals representative of food intake or other useful information to data management unit 10; (d) adapts handheld microprocessor unit 12 for simultaneous graphical display of blood glucose levels with information such as food intake; and, (e) adapts handheld microprocessor unit 12 for displaying information or instructions from a healthcare professional that are coupled to data management unit 10 from a clearinghouse 54. In the event that computer 48 absorbs all of the functions of unit 12 and data management unit 10, cartridge 42 or appropriate software is communicated directly to computer 48 instead. Computer 48 then performs all of the above functions. The manner in which the arrangement of FIG. 1A implements the above-mentioned functions and others can be better understood with reference to FIG. 2 discussed further below.

Alternatively, the functionality of handheld unit 12, computer 48, data management unit 10 and modem 52 can be replaced by a single integrated device. Such an embodiment is shown in Fig. IB, by a schematic block diagram of an integrated device 1. Device 1 includes a microprocessor 2 and a memory 3 connected to microprocessor 2. Memory 3 is preferably a non-volatile memory, such as a serial EEPROM. Memory 3 stores programs or script programs received from clearing house 54, measurements received from monitoring devices 16, 20 or 22, and the patient's responses. Microprocessor 2 also includes built-in read only memory (ROM) which stores firmware for controlling the operation of apparatus 1. The firmware includes a script interpreter used by microprocessor 2 to execute the script programs . The script interpreter interprets script commands which are executed by microprocessor 2. Specific techniques for interpreting and executing script commands in this manner are well known in the art.

Microprocessor 2 is preferably connected to memory 3 using a standard two-wire I^C interface. Microprocessor 2 is also connected to user input buttons 4, LED 5, a clock 6, and a display driver 7. Clock 6 indicates the current date and time to microprocessor 2. For clarity of illustration, clock 6 is shown as a separate component, but is preferably built into microprocessor 2. Display driver 7 operates under the control of microprocessor 2 to display information on display 8. Microprocessor 2 is preferably a PIC 16C65 processor which includes a universal asynchronous receiver transmitter (UART) 9. UART 9 is for communicating with modem 52 and a device interface 11. A CMOS switch 13 under the control of microprocessor 2 alternately connects modem 52 and interface 11 to UART 9.

Modem 52 is connected to a telephone jack 15 through modem jack 17. Modem 52 is for exchanging data with clearing house 54 through telephone line or any other suitable communication network 50. The data includes programs, e.g., script programs which are received from the server as well as responses to queries, device measurements, any required script identification codes, and the patient's unique identification code which modem 52 transmits to the clearing house. Modem 52 is preferably a complete 28.8 K modem commercially available from Cermetek, although any suitable modem may be used.

Device interface 11 is connected to device jacks 19A, 19B, and 19C . Device interface 11 is for interfacing with monitoring devices 16, 20, 22 which can include blood glucose meters, respiratory flow meters, blood pressure cuffs, weight scales, pulse rate monitors or any other suitable patient monitoring devices. Device interface 11 operates under the control of microprocessor 2 to collect measurements from the monitoring devices and to output the measurements to microprocessor 2 for storage in memory 3. In the preferred embodiment, interface 11 is a standard RS232 interface. In alternative embodiments, apparatus 1 may include multiple device interfaces to accommodate monitoring devices which have different connection standards.

As shown in FIG. 2, clearinghouse 54 receives data from a plurality of self-care microprocessor-based healthcare systems of the type shown in either FIG. 1A or FIG. IB, with the individual self-care health monitoring systems being indicated in FIG. 2 by reference numeral 58. Preferably, the data supplied to clearinghouse 54 by each individual self-care health monitoring system 58 consists of "raw data," i.e., test results and related data that was stored in memory circuits of data management unit 10, without further processing by data management unit 10. For example, with respect to the arrangement shown in FIG. 1A or FIG. IB, blood glucose test results and associated data such as food intake information, medication dosage and other such conditions are transmitted to clearinghouse 54 and stored with a digitally encoded signal that identifies both the source of the information (i.e., the system user or patient) and those having access to the stored information (i.e., the system user's doctor or other healthcare professional) .

As shall be recognized upon understanding the manner in which it operates, clearinghouse 54 can be considered to be a central server for the various system users 58 and each healthcare professional 60. Thus, clearinghouse 54 includes conventionally arranged and interconnected digital processing equipment, i.e., digital signal processor 57 which receives digitally encoded information from user 58 or healthcare professional 60; processes the information as required; stores the information (processed or unprocessed) in memory if necessary; and transmits the information to an intended recipient (i.e., user 58 or healthcare professional 60) .

In FIG. 2, rectangular outline 60 represents one of numerous remotely located healthcare professionals who can utilize clearinghouse 54 and the arrangement described relative to FIG. 1A or FIG. IB in monitoring and controlling patient healthcare programs. Shown within outline 60 is a computer 62 (e.g., personal computer) , which is coupled to clearinghouse 54 by means of a. modem (not shown in FIG. 2) and a telephone line 64. Also shown in FIG. 2 is the previously mentioned facsimile machine 55, which is coupled to clearinghouse 54 by means of a second telephone line 68. Using the interface unit of computer 62 (e.g., a keyboard or pointing device such as a mouse) , the healthcare professional can establish data communication between computer 62 and clearinghouse 54 via telephone line 64. Once data communication is established between computer 62 and clearinghouse 54, patient information can be obtained from clearinghouse 54 in a manner similar to the manner in which subscribers to various database services access and obtain information.

In particular, the healthcare professional can transmit an authorization code to clearinghouse 54 that identifies the healthcare professional as an authorized user of the clearinghouse and, in addition, can transmit a signal representing the patient for which healthcare information is being sought. As is the case with conventional database services and other arrangements, the identifying data is keyed into computer 62 by means of a conventional keyboard (not shown in FIG. 2) in response to prompts that are generated at clearinghouse 54 for display by the display unit of computer 62 (not shown in FIG. 2).

Depending upon the hardware and software arrangement of clearinghouse 54 and selections made by the healthcare professional via computer 62, patient information can be provided to the healthcare professional in different ways. For example, computer 62 can be operated to access data in the form that it is stored in the memory circuits of clearinghouse 54 (i.e., raw data that has not been processed or altered by the computational or data processing arrangements of clearinghouse 54) . Such data can be processed, analyzed, printed and/or displayed by computer 62 using commercially available or custom software. On the other hand, various types of analyses may be performed by clearinghouse 54 with the results of the analyses being transmitted to the remotely located healthcare professional 60. For example, clearinghouse 54 can process and analyze data in a manner identical to the processing and analysis provided by the self-care monitoring system of FIG. 1A or FIG. IB. With respect to such processing and any other analysis and processing provided by clearinghouse 54, results expressed in alphanumeric format can be sent to computer 62 via telephone line 64 and the modem associated with computer 62, with conventional techniques being used for displaying and/or printing the alphanumeric material for subsequent reference.

The arrangement of FIG. 2 also allows the healthcare professional to send messages and/or instructions to each patient via computer 62, telephone line 64, and clearinghouse 54. In particular, clearinghouse 54 can be programmed to generate a menu that is displayed by computer 62 and allows the healthcare professional to select a mode of operation in which information is to be sent to clearinghouse 54 for subsequent transmission to a user of the system described relative to FIG. 1A or FIG. IB. This same menu (or related submenus) can be used by the healthcare professional to select one or more modes of operation of the above-described type in which either unmodified patient data or the results of data that has been analyzed by clearinghouse 54 is provided to the healthcare provider via computer 62 and/or facsimile machine 55.

Operation of the arrangement of FIG. 2 to provide the user of the invention with messages or instructions such as changes in medication or other aspects of the healthcare program, e.g., instructional programs, is similar to the operation that allows the healthcare professional to access data sent by a patient, i.e., transmitted to clearinghouse 54 by a data management unit 10 of FIG. 1A or FIG. IB. The process differs in that the healthcare professional enters the desired message or instruction via the keyboard or other interface unit of computer 62. Once the data is entered and transmitted to clearinghouse 54, it is stored for subsequent transmission to the user for whom the information or instruction is intended. With respect to transmitting stored messages or instructions to a user of the invention, at least two techniques are available. The first technique is based upon the manner in which operational modes are selected in the practice of the invention. Specifically, in the currently preferred embodiments of the invention, program instructions that are stored in data management unit 10 and program cartridge 42 cause the system of FIG. 1A or FIG. IB to generate menu screens which are displayed by display unit 28 of microprocessor unit 12. The menu screens allow the system user to select the basic mode in which the system is to operate and, in addition, allow the user to select operational subcategories within the selected mode of operation. Various techniques are known to those skilled in the art for displaying and selecting menu items. For example, in the practice of this invention, one or more main menus can be generated and displayed which allow the system user to select operational modes that may include: (a) a monitor mode (e.g., monitoring of blood glucose level); (b) a display mode (e.g., displaying previously obtained blood glucose test results or other relevant information) ; (c) an input mode (e.g., a mode for entering data such as providing information that relates to the healthcare regimen, medication dosage, food intake, etc.); and, (d) a communications mode (for establishing a communication link between data management unit 10 and personal computer 48 of FIG. 1A or FIG. IB; or between data management unit 10 and a remote computing facility such as clearinghouse 54 of FIG. 2) .

In embodiments of the invention that employ a compact video game system for handheld microprocessor unit 12, the selection of menu screens and the selection of menu screen items preferably is accomplished in substantially the same manner as menu screens and menu items are selected during the playing of a video game. For example, the program instructions stored in data management unit 10 and program cartridge 42 of the arrangement of FIG. 1A or FIG. IB can be established so that a predetermined one of the compact video game switches (e.g., switch 32) allows the system user to select a desired main menu in the event that multiple main menus are employed. When the desired main menu is displayed, operation by the user of control pad 30 allows a cursor or other indicator that is displayed on the menu to be positioned adjacent to or over the menu item to be selected. Activation of a switch (e.g., switch 36 of the depicted handheld microprocessor unit 12) causes the handheld microprocessor unit 12 and/or data management unit 10 to initiate the selected operational mode or, if selection of operational submodes is required, causes handheld microprocessor unit 12 to display a submenu.

In view of the above-described manner in which menus and submenus are selected and displayed, it can be recognized that the arrangement of FIG. 1A or FIG. IB can be configured and arranged to display a menu or submenu item that allows the user to obtain and display messages or instructions that have been provided by a healthcare professional and stored in clearinghouse 54. For example, a submenu that is generated upon selection of the previously mentioned communications mode can include submenu items that allow the user to select various communication modes, including a mode in which serial data communication is established between data management unit 10 and clearinghouse 54 and data management unit 10 transmits a message status request to clearinghouse 54. When this technique is used, the data processing system of clearinghouse 54 is programmed to search the clearinghouse memory to determine whether a message exists for the user making the request. Any messages stored in memory for that user are then transmitted to the user and processed for display on display unit 28 of handheld microprocessor unit 12. Of course, the message may include an entire program, e.g., an instructional video. If no messages exist, clearinghouse 54 transmits a signal that causes display unit 28 to indicate "no messages." In this arrangement, clearinghouse 54 preferably is programmed to store a signal indicating that a stored message has been transmitted to the intended recipient (user) . Storing such a signal allows the healthcare professional to determine that messages sent to clearinghouse 54 for forwarding to a patient have been transmitted to that patient .

In addition, the program instructions stored in data management unit 10 preferably allow the system user to designate whether received messages and instructions are to be stored in the memory of data management unit 10 for subsequent retrieval or review. In addition, in some instances it may be desirable to program clearinghouse 54 and data management unit 10 so that the healthcare professional can designate (i.e., flag) information such as changes in medication that will be prominently displayed to the user (e.g., accompanied by a blinking indicator) and stored in the memory of data management unit 10 regardless of whether the system user designates the information for storage.

A second technique that can be used for forwarding messages or instructions to a user does not require the system user to select a menu item requesting transmission by clearinghouse 54 of messages that have been stored for forwarding to that user. In particular, clearinghouse 54 can be programmed to operate in a manner that either automatically transmits stored messages for that user when the user operates the system of FIG. 1A or FIG. IB to send information to the clearinghouse or programmed to operate in a manner that informs the user that messages are available and allows the user to access the messages when he or she chooses to do so.

Practicing the invention in an environment in which the healthcare professional uses personal computer in some or all of the above- discussed ways can be very advantageous. On the other hand, the invention also provides healthcare professionals timely information about system users without the need for a computer (62 in FIG. 2) or any equipment other than a conventional facsimile machine 55 in FIGS. 1 and 2. Specifically, information provided to clearinghouse 54 by a system user 58 can be sent to a healthcare professional 60 via telephone line 68 and facsimile machine 55, with the information being formatted as a standardized graphic or textual report 56. Formatting a standardized report 56 (i.e., analyzing and processing data supplied by blood glucose monitor 16 or other system monitor or sensor) can be effected either by data management unit 10 or within the clearinghouse facility 54. A preferred embodiment of the invention is focused on sending the patient an educational program corresponding to an educational need as assessed by the system of the invention. The adaptation of the system of FIGS. 1 and 2 for this purpose is shown in detail in FIGS. 3 - 15.

The operation of the preferred embodiment is illustrated in FIG. 15. FIG. 15 is a flow chart showing a preferred method of using the health management system for remotely monitoring a patient and for training the patient to comply with a treatment plan for his or her health condition. In step 202, the patient is tested with metering device 420 to produce device measurements 540. Typically, the test is self-administered by the patient. Next, measurements 540 are uploaded to patient computing device 320, step 204, and stored in local patient database 400.

Once device measurements 540 are stored in database 400, the patient enters logbook records 520 into database 400 using logbook program 480, step 206. Additionally, the patient plays educational video educational program 360, entering educational program responses into patient computing device 320. As the patient plays video educational program 360, the patient's educational program responses are scored to produce knowledge score 530A, comprehension score 530B, and attitude score 530C. Knowledge score 530A, comprehension score 530B, and attitude score 530C are stored as educational program response information 500 in database 400, step 208.

Next, educational program response information 500, logbook records 520, and device measurements 540 are transmitted through communication network 280 to clinic server 120 and stored in master patient database 180, step 210. In a typical implementation, clinic 100 manages the healthcare of hundreds of patients and the data for each patient is stored in master patient database 180. A clinician at clinician computer 200 downloads patient data of a particular patient for whom he or she is responsible from master patient database 180 to local clinician database 260, step 212.

The downloaded patient data is analyzed in clinician computer 200 using clinician data view program 920, step 214. As shown in FIG. 10, data view program 980 displays on clinician computer 200 graph 102 of selected subset of data 101. The clinician also analyzes knowledge score 530A, comprehension score 530B, and attitude score 530C to assess the patient's psychological state. Based on analysis of the patient data, the clinician determines an educational need of the patient for learning to comply with a treatment program, step 216. A first example of such an educational need is illustrated in FIG. 12. As indicated in electronic mail message 940, the clinician has determined that the patient needs to learn the health consequences of failing to eat balanced meals in a diabetes treatment plan.

A second example of an educational need is illustrated in FIG. 13. As indicated in electronic mail message 112 , the clinician has determined that the patient needs to learn the importance of taking medication. A third example of an educational need is illustrated in FIG. 14. As indicated in electronic mail message 121, the clinician has determined that the patient needs to learn how to treat diabetes while traveling. Of course, these are just a few examples of possible educational needs of the patient. The clinician may identify many other educational needs, such as the patient's need to learn coping skills, communication skills, and other social adjustment factors.

Once the clinician has determined the patient's educational need, he or she selects an educational program corresponding to the educational need, step 218, and embeds in an electronic message a pointer or a prompt to the educational program, step 221. The program will execute when the patient selects the pointer or reponds to the prompt. In the preferred embodiment, the educational program is selected to be either patient data view program 960, educational video educational program 360, or document view program 970 depending on the educational need determined by the clinician.

FIG. 12 shows an example of the clinician selecting data view program 960 as the educational program. The clinician embeds a pointer to program 960 in icon 110. The clinician further loads icon 110 with patient data from a specific day and instructions for program 960 to display the patient data in graphical form. FIG. 13 shows an example of the clinician selecting a educational program level of educational video educational program 360 as the educational program. The clinician embeds a pointer to the selected educational program level of video educational program 360 that has an educational content corresponding to the patient's educational need. FIG. 14 shows an example of the clinician selecting document view program 970 as the educational program. The clinician embeds a pointer to program 970 in icon 122. The clinician further loads icon 122 with an educational document retrieved from information service 440.

Next, the electronic message containing the embedded pointer is transmitted from clinician computer 200 to patient computing device 320 through mail server 140 and communication network 280, step 222. The selected educational program is then started on the patient computing device by selecting the embedded pointer in the electronic mail message, step 224, typically by clicking the icon in which the pointer is embedded with a mouse or pointing device.

As the patient works with the educational program, he or she continues the feedback loop with the clinician, step 226, by returning to step 202 and repeating the method described. With this continuous feedback loop between the patient and clinician, the clinician is able to monitor the patient's progress and effectively train the patient to comply with the treatment plan.

SUMMARY, RAMIFICATIONS, AND SCOPE Although the above description contains many specificities, these should not be construed as limitations on the scope of the invention but merely as illustrations of the presently preferred embodiment. Many other embodiments of the invention are possible. For example, in one alternative embodiment, the clinic server is eliminated from the system so that the clinician computer exchanges information directly with the patient computing device. The clinic server is presently preferred for performing resource intensive operations, such as storing large amounts of patient data, but the clinic server is not necessary to enable the system and method of the invention.
