Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future, i.e., any elements later developed that perform the same function, regardless of structure.

[0045] Unless otherwise explicitly specified herein, the drawings are not drawn to scale.

[0046] In accordance with aspects of the present disclosure, a health care system and method are disclosed for assisting a new mother who would like to monitor breastfeeding quality for an infant.

[0047] FIG. 1 presents a high level schematic diagram illustrating a health care system according to aspects of the present disclosure. The system of FIG. 1 includes a base station 102 in communication with a network 104, and also in communication with biometric sensors 106 for monitoring certain biologic condition of the infant and environmental sensors 108 for monitoring certain environmental conditions in proximity to the infant. Biologic conditions may, for example, include heart and breathing rate, movement and other breastfeeding-related indicators useful for determining whether the infant is asleep, awake, irritated, fussy, crying and so on. The environmental conditions, for example, may include temperature, sound types and levels, light coloration, patterns and intensity, odors and other indicators useful for influencing a state of the infant. A suitable base station and sensor configuration for this purpose may be obtained, for example, from Rest Devices, Inc. of Boston, Mass.

[0048] A remote server 110 is also in communication with the network 104 and may be operative for example to access information stored in an information store 112 indicating one or more new mother typing traits. The remote server 110 receives information from the sensors 106, 108 via the base station 102 to be interpreted as indicating one or more measures of breastfeeding quality for the infant,

[0049] The new mother is also able by means of a new mother communication device 114 to communicate with the remote server 110 via the network 104. For example, the new mother communication device 114 may be by a smartphone, tablet computer, personal computer or other device that can be identified to the new mother and be configured to communicate with the network 104. The new mother may, for example, communicate with the remote server 110 via the network 104 or another alternate network to provide a new mother perception of breastfeeding quality for the infant.

[0050] Based on the stored new mother typing traits, the biologic and environmental conditions, the new mother perception and certain goals of the new mother with respect to the infant's breastfeeding quality, the remote server 110 is operative to recommend at least one action to the new mother to be taken in support of managing or improving infant breastfeeding quality.

[0051] FIG. 2A illustrates an information flow for the remote server 110 according to aspects of the present invention. Server 110 begins by establishing certain input variables at step 202 that pertain to the infant and the new mother. For example, the server 110 may collect information to identify the new mother according to age, general temperament, and location (for example, zip code). The infant may be similarly characterized by age, gender, temperament and developmental stage. This information may be referred to generally as identified input trait variables, which are static and require collection once or only infrequently.

[0052] In addition to the input trait variables, certain information indicative of daily activities of the infant (for example, sleep, feeding and diapering) may be gathered together with information about the season, geography and weather, and local environmental conditions (for example, temperature and light profiles) via the base station 102 and sensors 106, 108, This information may be referred to collectively as identified input state variables, which are dynamic and require ongoing, periodic collection.

[0053] An important category of input trait variables is directed to new mother typing variables. These are used to characterize different groups of new mothers according to the kinds of infant care interventions they may be comfortable and capable of providing, thereby increasing the likelihood that interventions coached by the inventive system will be carried out by the new mothers. In one embodiment in accordance with the present disclosure, new mother typing is accomplished by causing the remote server 110 to transmit and administer a new mother questionnaire to the new mother via the new mother communication device 114. Information indicative of the answers that the new mother provides to the questionnaire are stored by the remote server 110 in the information store 112. As illustrated below, the questions administered to determine new mother typing variables may preferably be provided with discrete answers (options) to facilitate easy compilation by the remote server 110:

[0054] Examples of additional new mother typing questions are provided in FIG. 3C. The aforementioned questions and those set forth below may be referred to generally as metrics, or breastfeeding metrics, and may include or demonstrate quality of breastfeeding. Patterns may reflect how the questions, or a subset of these questions occur and/or reoccur throughout the course of a day, and from day to day.

[0055] Examples of information gathered for determining the second category of variables (input state variables) are illustrated in FIG. 3C. Information gathered may include tracking of the infant's daily activities (sleeping, feeding, diapering and so on); information about the date, season, day of the week and weather; and information about environmental conditions proximate to the infant (for example, temperature, sound and light). The significance of these variables can be evaluated, for example by querying the new mother with regard to associated new mother behaviors 306, baby breastfeeding parameters 308, and new mother perception factors 310. As illustrated in FIG. 3C, the questions administered to determine baby breastfeeding parameters 308 may preferably be provided with discrete answers to facilitate easier compilation by the remote server 110.

[0056] Returning to FIG. 2A, the server 110 employs a goal/problem-driven approach (Kairos) 204 to determine suitable interventions to be taken by a new mother to improve infant breastfeeding quality. New mothers begin by setting goals for infant breastfeeding quality. A problem detection engine 206 correlates the goals with known problems based on an analysis of the input variables 202. New mothers prioritize the goals based, for example, on their intuition, beliefs and individual preferences. For high priority goals and high impact problems, a customization intervention engine 208 selects certain interventions (for example, reminders, notifications, and encouraging messages) for action by the new mother.

[0057] FIG. 2B further illustrates an exemplary process by which goals evolve. At step 222, a new infant is added to a goal setting regime, which may be implemented for example as a software-guided planning system. An infant routine is created at step 224, either built by scratch at step 224a or based on existing templates at step 224b. Base on the selected routine, a base change to an element of the routine is recommended at step 226. The new mother may accept or decline this recommendation at steps 226a, 226b respectively. At step 228, the new mother may select a particular goal, or rely on the system to suggest a goal at step 230. The new mother accepts or rejects the recommended goal at steps 230a, 230b respectively.

[0058] Once a goal is selected, a further base change is recommended by the system at step 232, which can be accepted or declined at steps 232a, 232b respectively. If not accepted, the system suggests a goal change at step 234, which can be accepted or declined at steps 234a, 234b respectively. If the change is not accepted, the system may recommend a daily objective as an alternative at step 236, which can be accepted or declined at steps 234a, 234b respectively. If the goal has been completed at step 238, system returns to step 230 to suggest a new goal. Otherwise, the system returns to step 232 to recommend a further base change.

[0059] Recommended changes may stimulate a variety of actions to adjust the infant's environment and routine, for example, such as:

[0060] Set/encourage consistent feeding: [0061] Physical chart in baby's room with feeding routine check listfor reminder of instructions for additional care givers [0062] Baby bath product as part of daily routine [0063] Baby lotion product as part of daily routine [0064] Books are part of daily routine [0065] Release of fragrance at specific time (or human triggered).

[0066] Help child self sooth after feeding [0067] Auto pacifier dropped into crib. [0068] Speaking that play care-givers voice, songs or ambient sounds. [0069] Movement of mobiles [0070] Release of fragrance
Set/encourage consistent feeding routine:

[0071] FIG. 4 provides a schematic diagram illustrating a flow of information in a health care system described in accordance with aspects of the present disclosure; A control characteristic or condition 410 is established by a new mother 412, for example, by the goal/problem-driven approach 204 of FIG. 2. A comparator 414 (implemented, for example, as the remote sever 110 of FIG. 1) compares the control characteristic 410 with an observation 416 of the new mother 412, who acts effectively as a sensor 418 and provides the observation to the comparator 414 by answering a series of survey questions 420 presented at a new mother communication device 422. The comparator (for example, realized by the remote server 110 of FIG. 1), applies the goal/problem-driven approach 204 of FIG. 2 to determine a new mother intervention to be instructed through the new mother communication device 422 as action 424. This cycle is repeated while the observation 416 by the new mother 412 indicates a deviation from the control characteristic 410.

[0072] Comparator 414 is further illustrated as implemented by server 414a in FIG. 4. Server 414a gathers biometric and other sensory data via sensor(s) 418(a) placed in the vicinity of the infant, which may for example be used to determine infant breastfeeding patterns. Server 414a also gathers data from sensor(s) 418(a) that indicates new mother behaviors (for example, such as new mother responses to queries administered by the new mother communication device 422 to determine whether recommended interventions were administered, and new mother location and movement data provided by GPS sensors incorporated in the new mother communication device 422). Sensor(s) 418(a) may also provide data indicative of new mother perceptions of care (for example, via surveys administered via the new mother communication device 422).

[0073] By means further described with reference to FIGS. 7 and 8 herein, the server 414a applies the data inputs gathered by the server 414a to produce a probabilistic diagnosis 424 of potential problems which may for example be preventing infant breastfeeding characteristics and parent perception from reaching values consistent with the identified goals. Through further analysis of data as described by way of example with reference to FIGS. 7-9, server 414a selects an intervention plan 426 including one or more behavioral quanta 428 expressed as actions to be taken by the new mother for the purpose of carrying out an intervention. These behavioral quanta or actions may be displayed, for example, to the new mother via the new mother communication device 422. In this closed loop system, actions taken by the new mother influence infant breastfeeding characteristics in a direction towards or away from desired values and goals 410, thereby providing a basis for adjusting the associated intervention plan 426 and behavioral quanta 428.

[0074] In accordance with additional aspects of the present disclosure, FIG. 5 provides a schematic diagram illustrating an alternate flow of information in the described health care system. A control characteristic or condition 510 is established by a new mother 512, for example, by the goal/problem-driven approach 204 of FIG. 2. A comparator 514 (implemented, for example, as the remote sever 110 of FIG. 1) compares the control characteristic 510 with an observation 516 of the new mother 512, who acts effectively as a sensor 518 and provides the observation to the comparator 514 by answering a series of survey questions 520 presented at a new mother communication device 522. Additional sensors 518(a) (for example, including one or more of biometric sensors 106 and environmental sensors 108 of FIG. 1) are provided in proximity to an infant 532 for assessing characteristics indicative of or capable of influencing breastfeeding quality.

[0075] The comparator 514 (again realized, for example, by the remote server 110 of FIG. 1), applies the goal/problem-driven approach 204 of FIG. 2 to determine a new mother intervention to be instructed through the new mother communication device 522 as action 524. For example, if the action 524 instructs the new mother 512 to rock the infant 532 in order to urge the infant 532 to cease crying, action 538 may in addition be applied in advance by a device (not shown) in support of new mother action 524. This cycle continues to be repeated while the observation 516 by the new mother 512 indicates a deviation from the control characteristic 510.

[0076] In addition to new mother 512, secondary caregivers 526, 528 may assist new mother 512 concurrently with new mother 512 or at alternate times when new mother 512 is unavailable and be provided with communication devices 522 to receive instructions concerning new mother interventions. Secondary caregivers 526, 528 will most likely be taking action directed to the control characteristics 510 established by new mother 512.

[0077] Secondary caregivers 526, 528 may have parent typing characteristics that differ from the new mother 512. For example, this might be expected in the case where secondary caregivers 526, 528 are grandparents of the infant 532. With reference to FIGS. 2 and 3, parent typing may therefore be preferably performed by administering separate surveys to each of the new mother 512 and secondary caregivers 526, 528 to account for differences in caregiving tendencies and styles among the various caregivers. In this case, customization intervention engine 208 of FIG. 2 may select interventions 210 that are accordingly tailored to the caregiving tendencies and styles of each on-duty caregiver.

[0078] As illustrated in FIG. 5, in addition to actions 524 that may be instructed at communication device 522 as text-based instructions, notifications and reminders, action 524 may be instructed at communication device 522 by a live human coach (for example, by means of direct a FACETIME, SKYPE or other audio/video link), or alternatively by means of an interactive avatar that is animated by remote server 110 of FIG. 1. Some new mothers may find they are more at ease with this approach to receiving intervention instruction and additional guidance than with text-based instructions. The avatar may be implemented as an available array of many adviser/expert avatars (in effect, a Many Face God engine) having distinct styles, selectable to match with the caregiver's typing characteristics.

[0079] FIG. 6A provides an illustration of a digital coaching system for managing infant breastfeeding quality interventions according to aspects of the present disclosure. Experience suggests that a managed routine is essential to stabilizing and promoting good infant breastfeeding quality. In accordance with aspects of the present disclosure, the new mother is able to assemble and record a daily routine with the assistance of the remote server 110 of FIG. 1 via the new mother communication device 114.

[0080] The daily routine builder may preferably include transitional tasks to assist the infant in moving from one state to another.

[0081] As further illustrated in FIG. 6A, the remote server 110 of FIG. 1 may instruct the new mother to alter a pre-existing daily routine in order to promote an improvement to infant breastfeeding quality in line with new mother goals established, for example, as shown at step 204 of FIG. 2.

[0082] FIG. 7 depicts element of large data set modeling of infant and new mother behaviors in accordance with aspects of the present disclosure. This large data set may be stored, for example, in the information store 112 of FIG. 1, and interpreted by the remote server 110 in order to select new mother actions that are correlated with desired infant breastfeeding outcomes. As illustrated in FIG. 7, the large data set may be interrogated by the remote serve 110 of FIG. 1 to determine likely breastfeeding outcomes 702 (for example, including daytime feeding (DST), nighttime feeding (NST), feeding onset latency (SOL), night waking count (NW.sub.ct) and night waking duration (NW.sub.dur)).

[0083] Remote server 110 may interrogate the data set to model outcomes 702 as a function of infant biologic conditions 704, infant environmental conditions 706 in proximity to the infant, and new mother behaviors 708. New mother perception of breastfeeding outcomes may also be modeled by the remote server 110 of FIG. 1 as a function of breastfeeding outcomes 702 and infant biologic conditions 704. As a result of this modeling, the remote server 110 of FIG.1 can operate new mother behavior data 708 customization intervention engine 208 of FIG. 2 to select interventions 210 that are tailored to the new mother tendencies and styles the new mother and likely to demonstrate the breastfeeding outcomes 702 of FIG. 7 and new mother perception 710 that are consistent with new mother's goals.

[0084] In some aspects, it may be beneficial to provide ongoing and frequent evaluation and feedback to new mother through Bayesian behavioral methods. The use of these Bayesian methods allows for diagnosis, feedback and intervention in real-time and in non-linear ways. In linear methods, such as a decision tree approach, a series of questions or identifications is navigated one by one, where a first response must be received or acknowledged before a second response can be obtained. Through non-linear methods, interventions and guidance may be provided in a quicker and more robust fashion. Non-linear methods also account for biological changes in the infant as well as the new mother, such as aging or disease, and also account for cognitive changes whereby the participants learn and modify their own behavior over time.

[0085] One method of the present invention uses ongoing and frequent gathering of information, probabilistically determining a most likely diagnosis, and providing feedback. This method includes receiving data, including human behaviors and resultant biological processes. The receipt of this data allows for probabilistic diagnosis and probabilistic determination of high impact questions to be asked or data to be gathered based upon the probability evaluated. This allows for real-time modification of the system, and ongoing reassessment or retargeting of the behavior quantum based upon the frequent tracking. Frequency of tracking or inquiring may be every second, every minute, every hour, every half day, every day, or at other desired intervals.

[0086] The care giving regarding infants sometimes involves rapid change of different mechanisms and therefore it would be helpful to rapidly change and update the problem or goal of a control system. In particular, babies are developing rapidly and tend to change their behaviors on the time scale of days or weeks. Additionally, new mothers are rapidly learning new skills and developing expertise and new perspectives, also often on the time scale of days or weeks. Ideally an effective behavioral control system would update its learning, its data gathering, and/or its interventional recommendations hourly, daily, or weekly.

[0087] The action of the control system may be dependent on the process output or result; where feedback from the process variables may be used to alter the control system over time. In this case the action of the control system would be influenced by either ongoing new mother behavior or the observed baby breastfeeding. A closed loop control system involving a probabilistic determination of problems or goals (e.g., with new set points), which are suggested to and confirmed by the primary user, may be beneficial. For example, in this closed loop system, after a desired goal or problem has been established, the system then initiates a closed loop control process to move toward the desired outcome by establishing and reinforcing behavior change.

[0088] The probabilistic determination of the problem or goal of the target individual is then matched to behavioral quantum. The behavioral quantum is understood as involving a discrete and explicit behavioral change packet of action(s) for a particular goal or target outcome that is delivered for implementation at and over a particular time period. This concept is illustrated by FIG. 6B, which depict a series of behavioral quanta (BQ) 621-625 defining actions to be administered by a new mother over a three-day period. Each of the three days in this period begins with the administration of BQ.sup.1 621 at approximately 9:30 AM, which may for example represent a new mother intervention to wake an infant. Similarly, BQ.sup.2 622 and BQ.sup.3 623 are administered in succession each day, beginning at approximately 7:00 PM. BQ.sup.2 and BQ.sup.3 may, for example, represent new mother interventions to feed and rock the infant, respectively.

[0089] BQ.sup.4 624 and BQ.sup.5 625 are administered somewhat differently from BQ.sup.1 621, BQ.sup.2 622 and BQ.sup.3 623. On Day 1, BQ.sup.4 624 and BQ.sup.5 625 are administered in succession starting at about 1:00 AM, On Day 2, the order of administration is reversed (BQ.sup.5 is administered before BQ.sup.4), and on Day 3, the start time for the initially-administered BQ.sup.5 is advanced to 3:00 AM. BQ.sup.4 and BQ.sup.5 may, for example, represent caregiver interventions to feed and rock the infant, respectively. With a goal to extend the infant's period of nighttime sleep, BQ.sup.4 and BQ.sup.5 may for example represent caregiver interventions to feed and walk the infant, respectively. Beginning on Day 2, the order of administration of BQ.sup.4 and BQ.sup.5 is reversed, based on an analysis of data suggesting that initially walking rather than feeding the infant effectively extends the time between successive feedings to promote longer sleep cycles.

[0090] Returning to FIG. 7, the aforementioned Bayesian behavioral method may include a closed loop control system, which relies upon continual or repeated monitoring of progress towards a particular goal. As such, the behavioral change toward that goal can be increased or slowed down as needed, or the behavioral quantum can be switched for a new behavioral quantum as necessary. In typical clinical settings, behavioral therapy usually includes open loop control systems, where after a goal is determined a behavioral change is then implemented, but without continual monitoring toward that goal. The probabilistic approach with continual feedback and modification allows the system to be changed and the behavioral quanta to be taken into account to provide for effective intervention. There may be more than one behavioral quanta that may effectively solve an individual problem or aid in the attainment of the individual goal, and also multiple different problems may be solved (or goals reached) by an individual behavior quantum. The behavioral quantum that is recommended to the new mother can be drawn from an outside goal group without changing the overall goal, and the new mother need not be made aware of the modification. Such changing may be made during use, at regular and/or irregular intervals, such as daily or biweekly. In this way, novel behavioral therapy techniques can be developed and tailored to a new mother.

[0091] FIG. 8 depicts a data assimilation hierarchy for managing the large data set modeling depicted in FIG. 7. The hierarchy is introduced as a mechanism for quantizing and reducing a large volume of data for a population of infants to a size and form that is suitable for data analysis. With reference for example to FIGS. 4A, 4B and 5, biometric data including biorhythm data 802 is collected for each infant via infant sensors 416a, 518, and indicates a feeding state for an infant. This feeding state information may be sampled and collected by comparators 414, 514 (implemented by server 110 of FIG. 1). Server 110 is then operative to process this information to produce quantized data 804 that establishes feeding states and then further reduces this data to event data 806 that assigns feeding states in 10 minute intervals.

[0092] The event data 806 is analyzed to produce daily summary data 808, which may be characterized for example by seven distinct baby feeding variables BS_1 through BS_7, selected for example from among baby feeding parameters 308 as depicted in FIG. 3. Summary data 808 may be accumulated daily for each of a period of days, with the variables BS_1 through BS_7 calculated by the server 110 as a function of one or more of event data 806, quantized data 804, biorhythm data 802 and caregiver data (for example, as provided via sensor(s) 418 and/or survey questions 420 as depicted in FIG. 4).

[0093] Data describing new mother routines and habits for the infant is also collected and assembled by the server 110. For example, summary data 810 may be accumulated on a weekly basis for parent behavior variables PB_1 through PB_11, selected for example from parent behavior variables 306 as depicted in FIG. 3. Weekly summary data 812 characterizing baby feeding variables BS1_1 through BS_7 may be assembled from the daily summary data 808 characterizing these variables. The most significant data summarizing parent behavior and baby feeding characteristics may be extracted, for example as parent behavior data 810a and baby feeding data 812a, respectively. From this data, additional data 810b may be prepared for certain family variables Fam_1 (for example, including behaviors and trends among multiple infant caregivers and/or multiple infants cared for by a common caregiver).

[0094] In addition, parent or caregiver perceptions of infant feeding and caregiving effectiveness may be obtained as summary data 816 (for example, as provided via caregiver surveys 420, 520 as illustrated in FIGS. 4A, 4B and 5). Caregiver surveys may also serve as the source of data for summary data 814a, 814b, for example characterizing caregiver type traits Parent typer1-Parent typer9. Appendix 1 provides sample survey questions that may be used to assess caregiver type traits Parent typer1-Parent typer9.

[0095] FIG. 9 depicts an analysis engine for analyzing the data described with reference to FIG. 8. The analysis engine is preferably implemented as a neural network 900, which applies at least a portion the large-scale data set of infant and caregiver information acquired according to the data assimilation hierarchy of FIG. 8. This portion of the data is used as training data 904 for building probabilistic models for determining best infant feeding goals, interventions and outcomes 906 based on baby feeding data 812 and parent behavior data 810 of FIG. 8. Best goals, interventions and outcomes 906 are used, for example, to perform the probabilistic diagnosis 424 and produce the associated intervention plan 426 depicted in FIG. 4B. Feedback 908 based on the effectiveness of intervention plan 426 (for example, as evaluated via survey questionnaires 420 of FIG. 4B) is preferably applied to further train the network 900.

CONCLUSION

[0096] It will be understood that, while various aspects of the present disclosure have been illustrated and described by way of example, the invention claimed herein is not limited thereto, but may be otherwise variously embodied according to the scope of the claims presented in this and/or any derivative patent application. It should noted, for example, that although the examples provided in the specification are specificaly directed to caregiver management of infant feeding quality, these same principles may be readily applied to many other caregiver applications. For example, the disclosed invention could additionally be applied managing elder care quality administered in a nursing home or other assisted living facility by a variety of individual caregivers.
