METHOD AND SYSTEM FOR IMPROVING ADHERENCE WITH A DIET PROGRAM OR OTHER MEDICAL REGIMEN

PRIORITY CLAIM

This invention claims priority from US Provisional Application 60/165,518, filed November 16, 1999.

FIELD OF THE INVENTION This invention relates to an interactive computerized system and process for behavior analysis and feedback, and more particularly to a system for monitoring intake and providing feedback according to a plan.

BACKGROUND OF THE INVENTION Diet and lifestyle are key factors in chronic medical conditions such as obesity, cardiovascular disease, diabetes, cancer, and many other conditions. As a result, there are hundreds of diets - fad diets, celebrity promoted diets, and medically based diets. Yet as a whole, Americans still eat a high fat, high calorie, junk food diet. Also, diet programs are notorious for the poor adherence by the dieters.

A problem with existing diets, weight loss programs, and healthy regimens is that the diets are very difficult to faithfully follow, or adhere to. The task of keeping track of what is healthy or required by the diet is so tedious that, as a result, many diet program participants return to fatty foods simply for convenience and lack of sufficient interest to overcome the tedium. Another problem is that the present systems do not provide enough measurement and feedback to let one know how they are progressing. Even with diet programs that require the dieter to visit a center to weigh in, the dieters are nevertheless on their own most of the time. Finally, food labeled as healthy food is usually more expensive than fattier foods. The following patents are examples of the prior art discussed above. US Patent No. 5,890,128 to Diaz et al. discloses a hand held individually customized interactive integrated circuit device for nutrition and exercise management. The device of Diaz et al. includes built in storage of extensive food lists with associated caloric and fat contents. Diaz et al. incorporates storage of exercises with associated activity caloric values or rates. Diaz et al. utilizes the individual's personal characteristics such as sex, age, weight, height, frame size, life style and goals with programmed calculations to derive optimum suggested weight, metabolic rate, daily caloric/fat intake targets, exercise targets and exercise/daily calorie burning rates. Diaz et al. tracks daily and historical individual caloric input/output, fat input, and weight which can be viewed in the form of charts and graphs. Optional medical programs take into consideration special dieting, medication and exercise requirements of patients with diabetes, high cholesterol, heart ailments, hypoglycemia and other diseases. Diaz et al. is good at tracking historical data but fails to provide a system that will automatically generate a food order for home delivery based on the derived information. US Patent No. 5,673,691 to Abrams, et al. discloses a hand-held computer that prepares and monitors a goal-oriented weight, nutrition and exercise control program. Visual and audio prompts tell users when to eat and exercise, and provide suggestions for what to eat. Abrams et al. teaches assisting the user in setting safe goals for desired weight loss and the time required to achieve the loss. The user follows menu and exercise programs suggested by the system. The system records and analyzes the user's food consumption, exercise and weight loss programs. Finally, the computer displays feedback information regarding the user's progress towards achieving the desired weight. If the users have planned which meals they will select from a set of future recommendations, then the planned meals can be presented in such a way as to make selection and recording of the meals simple and quick. Also, meal planning allows the Behavior Planning routine to build a shopping list for the users to ensure they will have the necessary food on hand to prepare planned meals.

Diaz et al. is good tool for locally administering a weight loss program, however it fails to provide a system used for controlling diets for other medical purposes that will automatically generate a food order and make suggestions according to food pricing and availability information from a food delivery system.

What is needed is a system and method to measure a healthy diet while making it convenient and easy to place orders, learn about and try new foods that are acceptable to their diet program and their measured intake.

SUMMARY OF THE INVENTION

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

FIGURE 1 is a block diagram of the present invention; and

FIGURE 2 is a flow diagram of the method performed by the present invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

As shown in FIGURE 1 , the present invention includes a plurality of user devices 20, a program server 22 and a delivery system 24, all of which are coupled to a public or private communication network 26. The user devices 20 can be of varying types as will be described in more detail below. The user device 20 is a computer device that includes a processor 32 and a display 34, an input device 35 and memory 36 coupled to the processor 32. The processor 32 couples to the public or private communication network 26 via network accessibility software pre-stored in the memory 36. The user devices 20 use the display 34 to inform the users that input information is desired. The user is a patient, a caregiver for the patient, or some other person requiring program information, such as diet program information. Preferably, the display 34 includes an alphanumeric display capable of displaying questions corresponding to the user or patient. The user device 20 receives from the user using the input device 35 answers to the displayed questions. For example, if the displayed question asks what is the user's/patient's weight that day, the user enters the patient's weight into the user device 20 using the input device 35.

The input device 35 includes a keypad or keyboard, such as a television remote control, or is a keypad with a restricted set of keys by which the user increments, decrements, or accepts a value to be entered for the patient, such as the patient's weight for that day. In an alternate embodiment, the input device 35 is a monitoring device that generates a monitored signal and automatically sends the monitored signal to the processor 32. The type of monitoring device used by each user is dependent upon the user's diet. For example, for a weight loss patient, the monitoring device is a weight scale. For a diabetes patient, the monitoring device is a blood glucose meter for measuring the patient's blood glucose concentrations. For an asthma patient, the monitoring device is a peak flow meter for measuring the patient's peak flow rates. Such monitoring devices for recording and transmitting measurements are well known in the art. Alternative embodiments of the user device 20 may include a wide variety of other devices, possibly including electronic toy (such as a "key employee" or "virtual pet"), a telephone in connection with an interactive voice response system, a television set-top box interacting with a cable or satellite television interactive system, a medical device operated at a medical personal office, or any other system by which the user can enter information to be used by the program server 22. In one embodiment, the public or private communication network 26 is the Internet. The messages sent between the program server 22 and the user devices 20 over the Internet are formatted using a communication protocol, such as TCP/IP, HTML, or a combination thereof. The public or private communication network 26 can also be a direct connection via a modem or some other means, a local area network or a comparable communication network.

The program server 22 includes a processor 44 and memory 46. The program server 22 determines diet program information for each user based on user profile information pre-stored in the memory 46 and the information received from the user devices 20.

Also referring to FIG. 1, the delivery system 24 also includes a processor 50 and memory 52 for processing food delivery requests from the user devices 20 or the program server 22. An example of a delivery system coupled to users over a public network are Internet or web grocers that compile and deliver food orders based on food lists received from an order executed over the Internet.

The processor 44 of the program server 22 includes a program application previously installed. The program application is a controlling software application executed by server 22 that includes the following components: a script generator; a script assignor; and a report generator. The script generator generates script programs from script information previously entered by a program server coordinator or health care professional. The script programs are executed on the user devices 20 to display queries to the users, receive responses to the displayed queries, collect monitoring device measurements and transmit responses and measurements to the program server 22. The memory 46 in the program server 22 stores the responses and measurements. The memory 46 includes a look-up table that contains a list of the patients to be monitored and for each patient, a corresponding patient identification code and a respective pointer to at least one script program assigned to the patient.

The program application also includes a database, a diet composer component and a diet suggestion component. The database is stored in memory 46 and includes program information. The program information includes food items, patient food preferences, recipes with dietary information such as calories and fat content, model meal plans and patient profile information. The patient profile information includes weight history, weight goals, food history, food preferences, demographic information and patient shopping lists. The diet composer component selects food items based on the model meal plan, patient food preferences, patient profile information and patient information entered via the input device 35 and food cost and availability information provided by the delivery system 24. The diet suggestion component suggests new food items or substitutions in the model meal plan based on the selected food items. The components of the program application can be distributed over the system - the delivery system 24 or the user devices 20.

In an alternate embodiment, the application program includes a point system component that asks a user to enters points associated with certain foods. The point system component compares the amount of entered points to predetermined meal plan limits and creates meal plans according to this comparison. In still another embodiment, the input device 35 of the user device 20 includes a bar code scanner that allows users to scan the bar code present on food packages to record food usage or automatically order refills. The processor 32 and memory 36 in the user device 20 further includes a program that retrieves prestored information pertaining to the food package scanned. The program records the retrieved information as being consumed by the user, being requested by the user for reorder, or being used for some other purpose.

The program server 22 also generates a program adherence value. The program adherence value is a value that indicates how well the patient is adhering to the program. The program adherence value is calculated according the patient's determined diet or meal plan, predefined goals, the patient's food intake and other input information.

FIGURE 2 illustrates the process performed by the components illustrated in FIGURE 1. First, at block 100, the program server 22 sends a query to the patients. Then, at block 104, the patients or users replies to the query by answering the query and sending the answers to the program server 22. At block 108, the program server 22 determines a meal or diet plan for each patient according to the patient's reply to the query and previous food order information. Next, at block 112, the program server 22 generates a food list according to the determined meal or diet plan and sends the food list to the delivery system 24. Finally, at block 116, the delivery system 24 prepares a food order according to the food list, delivers the food order to the patient and sends information regarding the food order to the program server 22. After block 116, the process returns to block 100.

The program server 22 generates or prepares food lists based on specific goal achievement, such as reducing fat intake to 20%, lowering cholesterol to 100, losing 10 pounds, etc. As such, the program server 22 must calculate food intake and then determine a list of foods that fits into the meal plan based on the calculated food intake.

The queries sent by the program server 22 provides questions that allow the program server 22 to determine each patient's goals and preferences, monitor each patient's weight, diet choices, satisfaction with the food items in the food order and food choices available on the meal plan, allow patients to make food substitutions and present to the patient special offers and financial incentives to make food choices, as determined by the program server 22 from information received from the delivery system 24, prestored pricing information or some other pricing source. The queries also include, depending upon when the query occurs, a hierarchy of user interface windows, such as those in the HTTP format. These windows include links to patient information, program adherence, food choices, etc. The links when activated by the patient send the patient to other pages or window generated by the program server.

In another embodiment, the program server 22 also tracks various types of data for market research that will enable researchers to learn more about the interaction between disease and diet.

In still another embodiment, the program server 22 keeps track of the progress of a group of participants and feeds back combined progress information to an individual participant. This makes small individual changes seem more important and helps motivate the patient. For example: a diet patient receives the following message from the program server 22: "the weight club of Northern California lost 900 pounds today! Keep up the good work!" The user device 20 can alternately be a remotely programmable appliance, such as a Health Buddy made by

Health Hero Network, that is updated, monitored, and reprogrammed according to protocols assigned to the patient at the program server 22. The remotely programmable appliance is remotely manipulatable by the operator administering the diet through the program server 22.

The following is an example of a diet program interaction using the process illustrated in FIGURE 2. The first query from the program server includes the following questions: How much do you weigh?

How tall are you? How old are you? How much do you exercise? What is your weight goal? After the program server receives the participant's reply to the query, the program server assesses the participant's profile information determines a diet plan according to the participant's profile information. The program server sends the participant the following response that includes another query:

Your ideal weight is 170. You can lose 10 pounds in less than 3 months if you stick to a 1500 calorie

20% fat diet.

Would you like help assembling a grocery list for this diet?

The patient, or dieter in the example above, can also select food items from a food list presented on a web site, or the user can express some preferences based on food choices presented on the web site. The user's selections or expressed preferences are then used by the program application to generate a diet regimen. The user's food selections or preferences could also be mailed in, and entered at the program server 22 and used accordingly.

The present invention as described and shown by example above measure and reward user adherence to a healthy diet while making it convenient and easy to learn about and try new foods that are acceptable to the user's diet program and their measured intake. While the prefeπed embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
