    Description


    [0001] The following relates generally to medical monitoring of patients. It finds particular application in conjunction with patient monitor displays, and will be described with particular reference thereto. However, it will be understood that it also finds application in other usage scenarios and is not necessarily limited to the aforementioned application.

    [0002] Central monitoring of patients in a healthcare environment typically occurs in a healthcare treatment center such as a hospital ward, emergency department and the like. Many patients are monitored simultaneously by physiological sensors which transmit measurements of vital signs to a central monitoring system. Vital signs can include various measures of body temperature, heart rate, blood pressure, respiratory rate, and the like. The transmitted measures are received and display typically in a waveform and/or a numeric format. The vital signs for the group of patients being monitored are typically displayed on a common display, which provides an overview of the current status of each patient to healthcare practitioners involved in the treatment facility. Vital signs can be sourced which means a set of vital signs are associated with a selected patient. Sourced vital signs can be transmitted or not. For example, a patient may accidentally disconnect a sensor which interrupts transmission. The sensor or vital sign associated with the sensor is still sourced and to be displayed, but no data is transmitted. This can indicate an alarm or alert condition.

    [0003] The display of the patient group is often organized by physical location such as by bed location. The display includes for each patient a sector or display space. The patient sector typically includes a header space which identifies the patient and/or location, and any alarm conditions. The patient sector includes the waveforms of vital signs and alphanumeric measures for the patient. For example, an ECG waveform is displayed with a numeric value of the current heart rate, and a plethysmograph waveform is displayed with a SpO2 numeric value. Additional numeric values can be reported in space adjacent to waveforms such as respiration rate, non-invasive blood pressure (NBP), etc. The display of the patient group is typically organized into columns of the patient sectors.

    [0004] Displays can include up to 16 patient sectors on a single display or up to 32 patient sectors on a dual display. Displays are strategically placed in the treatment facility to communicate the state of each patient quickly to the healthcare practitioners such as doctors, nurses, aides, etc. Displays are often located in and around nursing stations, central locations, or locations frequency passed by the healthcare practitioners. The number of displays is often limited due to cost, and/or available physical space to place the displays. Moreover, expanding the number of displays can reduce the effectiveness by increasing the time to locate information about patients, or causing a healthcare practitioner to interrupt a task or change focus to assess the situation.

    [0005] The displays are organized for fast visual comprehension with a consistent organization. For example, the location of patients on the display is consistent. The organization within a patient sector is consistently organized such as header information at the top of the sector, waveforms on the left side of the sector in a list format, and numeric data on the right of each waveform. However, some patients are more acute than others and monitoring needs vary. Although the treatment facility may have a baseline of certain waveforms to be monitored for every patient, other waveforms may be helpful for certain patients. Furthermore, acuity level for a patient can change over time and therefore monitoring needs for each patient may change over time.

    [0006] One basic approach is to assign a fixed sector space to each patient. Patient sectors are typically placed within a single columnar display or a multi-columnar overall display. A fixed sector space can be quite large to accommodate different patient needs and limited by the addition of more overall display space. A modified approach is dividing the space differently between columns of patient sectors. For example, a first column is divided into 4 patient sectors, while a second column is divided into 2 patient sectors. The modified approach creates problems with the overall order of patients and does not completely address variability between patients, does not address variability in acuity level of an individual patient, and typically means moving the location of the sector from one column to another to increase the size.

    [0007] Another approach is to ask the healthcare practitioner to assign space to different patient sectors. This is typically accomplished with the healthcare practitioner interacting with the system, often with a password protected secure layout, and manual adjustment of the size. One modified approach to reduce the time required to optimize space is a minimize function which leaves only the patient header visible. Another approach includes the use of paging of the display. However, the interaction of the healthcare practitioner with the system to either fixed the format, minimize individual sectors, or page the display interrupts patient care tasks and/or diverts attention away from patient care. For example, in a team approach, designating who makes the modification, how the modification is made, and when interrupts the information flow to the healthcare provider team. System interactions by more than one member means a healthcare practitioner stopping to interact with the system versus obtaining visual information while providing patient care or moving from one location to another preparing for the next patient interaction. None of these approaches involve the current patient needs, but rather focus on the form of the information delivery.

    [0008] US 2013/0044111 A1 discloses a dynamic central monitoring station having multiple touch screens for displaying numerical and graphical representation of vital statistics of one or more patients. The central monitoring station is connected to one or more bedside monitors and telemetry devices. The multiple touch screens are configurable to simultaneously display real time and historic patient data corresponding to a plurality of patients. One screen serves as a dedicated display screen for the review of individual patient data while the remaining screens continue to display vital statistics for all of the monitored patients.

    [0009] WO 2012/085762 A2 discloses a patient monitoring station comprising: a display that displays a plurality of sectors, each sector including one or more tiles; a controller configured to display patient data received from a patient information server in a corresponding sector of the display, the controller programmed to or including means to: populate the tiles of the sectors with patient data according to a selected clinical theme.

    [0010] US 2012/0095778 A1 discloses a patient monitoring station including a display that displays a plurality of sectors. A controller displays the patient data received from one or more remote medical devices in a corresponding sector of the display. The controller is programmed to collapse one or more sector in response to one of (1) not receiving patient data from the corresponding remote patient monitor or (2) receiving patient data not indicative of a pending patient event or alarm condition; and expand at least sectors that receive patient data indicative of a pending patient event or alarm condition.

    [0011] US 2005/0229110 A1 relates to a method of optimizing the presentation on a display screen of objects of a user interface which can be freely positioned and scaled by means of control elements. This is realized by means of a predetermined calculation rule in such a manner that the objects can be automatically varied between a still readable minimum size and a selected maximum size in dependence on the object contents, selected preferred settings and the available display resource on the display screen, and that the available display screen surface is optimally filled, possibly while eliminating less important details of the object contents and while changing the display mode of the object contents and/or the object as well as while avoiding mutual overlapping of the objects.

    [0012] The following discloses a new and improved method and system for automatic real-time changes to the size of a patient's data display which addresses the above referenced issues, and others.

    [0013] In accordance with one aspect, a medical monitoring system includes one or more electronic processors and one or more display devices. The one or more electronic processors are configured to receive vital signs of each a plurality of patients and dynamically configure in real-time a display of the received vital signs which includes for each patient an individually assigned patient sector display sized from available space for the display based on a priority order. The priority order is based on a set of rules. Assignment of space to the patient sector displays is performed iteratively, wherein the space is assigned in increments to each patient sector display, based on the priority order, until all unassigned space is assigned. The one or more display devices displays the configured display of the plurality of patient sector displays.

    [0014] In particular examples, the set of rules may include the assignment of space: first to sectors with a user-specified minimum size, second to sectors with one or more user-specified data elements, third to sectors smaller than a predetermined minimum sector size, fourth to smaller sectors, fifth to sectors with space assigned to all sourced vital signs, sixth to sectors with a user-specified maximum sector size with the maximum size assigned, and seventh to sectors with no sourced vital signs.

    [0015] In accordance with another aspect, a method of patient monitoring includes receiving vital signs of each of a plurality of patients and dynamically configuring in real-time a display of the received vital signs which includes for each patient an individually assigned patient sector display size from available space for the display based on a priority order. The priority order is based on a set of rules. Assignment of space to the patient sector displays is performed iteratively, the space being assigned in increments to each patient sector display, based on the priority order, until all unassigned space is assigned. The configured display of the plurality of patient sector displays is displayed.

    [0016] In particular examples, the assigning may include: assigning unassigned space first to sectors with a user-specified minimum size; assigning unassigned space second to sectors with one or more user-specified data elements; assigning unassigned space third to sectors less than a predetermined minimum sector size; assigning unassigned space fourth to smaller sectors; assigning unassigned space fifth to sectors with space assigned to all sourced vital signs; assigning unassigned space sixth to sectors with a user-specified maximum sector size and the maximum size assigned; assigning unassigned space seventh to sectors with no sourced vital signs.

    [0017] One advantage is a dynamically variable sized patient sector.

    [0018] Another advantage resides in dynamically changing the patient sector as the patient acuity changes.

    [0019] Another advantage resides in accommodating different monitoring needs among individual patients in a monitored patient group.

    [0020] Another advantage resides in eliminating competing healthcare practitioner interactions to make changes in display configurations.

    [0021] Still further advantages will be appreciated to those of ordinary skill in the art upon reading and understanding the following detailed description.

    [0022] The invention is set out in the appended claims.

    [0023] The invention may take form in various components and arrangements of components, and in various steps and arrangement of steps. The drawings are only for purposes of illustrating the preferred embodiments and are not to be construed as limiting the invention.

    FIGURE 1 diagrammatically illustrates an embodiment of the automatic real-time changes to the size of a patient's data display system in an exemplary treatment facility with an exemplary partial patient monitoring display in an exploded view.

    FIGURE 2 illustrates an exemplary of a display with dynamically changed variable sized patient sectors.

    FIGURE 3 illustrates another exemplary of a display with dynamically changed variable sized patient sectors including a patient sector with differently sized vital sign displays.

    FIGURE 4 flowcharts one method of automatic real-time changes to the size of a patient's data display.



    [0024] With reference to FIGURE 1, an embodiment of the dynamic change to patient data display system in an exemplary treatment facility 10 with an exemplary partial patient monitoring display 12 in an exploded view is diagrammatically illustrated. The treatment facility is shown as one physical location, but can include geographically distributed patients. The treatment facility monitors multiple patients 14. Each patient can have one or more monitoring devices 16 or sensors which sense physiological activity and transmit measurements of the physiological activity or vital sign to a computer device 18. The sensing device can transmit over a network which is wireless, wired, or a combination. The sensing device can sense one or more measures of patient vital signs. The sensing devices can be the same or different between patients. For example, a first sensing device of a first patient 20 senses and transmits SpO2 measures, a second device of a second patient 22 senses and transmits SpO2 and ECG measures, and a third device of a third patient 24 senses and transmits SpO2, ECG, and ST segment measures. The sensing devices can process the measures and transmit values or waveforms, or transmit raw data with further processing of measures into graphical illustrations or waveforms performed by the computer device 18.

    [0025] The computer device 18, which includes one or more electronic processors, is programmed to receive vital signs of a plurality of patients and dynamically configure in real-time the display 12 of the received vital signs on a display device 26. The computer device 18 can be programmed further to source the individual sensing devices and/or vital signs of the patients, e.g. associate a set of vital signs with a patient, verify operational status, and the like. The display device can be visibly positioned to healthcare practitioners such as at a nursing station 28, mounted on a central wall 30, and the like. In other embodiments, the display device is included in the computing devices of individual healthcare practitioners. The display 12 includes a plurality of patient display sectors, and for each patient an individually assigned patient sector 32 display sized from available space for the display based on a priority order.

    [0026] The computer device assigns available space determined from the height of a column, e.g. number of pixels, of the display device incrementally to each variably sized patient display sector. Available space is assigned to each sector individually. Available space is assigned in a priority order. Each sector is sized individually to include a patient header space and graphical illustrations of one or more vital signs of the vital signs for the patient.

    [0027] The priority order is based on a set of rules. The set of rules can include the assignment of unassigned space, first to sectors with a user-specified minimum size, second to sectors with one or more user-specified data elements, third to sectors smaller than a predetermined minimum sector size, fourth to smaller sectors, fifth to sectors with space assigned to all sourced vital signs, sixth to sectors with a user-specified maximum sector size with the maximum size assigned, and seventh to sectors with no sourced vital signs. For example, each sector is initially assigned a height or size. Sectors can be organized based on the rules into a heap data structure ordered according to the rules. The sector at the top of the heap data structure is assigned space in increments of a graphical illustration of a vital sign or waveform. Header space for each patient sector can be initially assigned or alternatively header space included in the initial assignment of vital sign space. After the assignment to the sector, the heap data structure is resorted and the process repeated until all unassigned space is assigned to sectors in the column.

    [0028] The rules can limit sector size to a predetermined minimum sector size based on site specific policies, such as a minimum number of vital signs or ideal sector size targets. The rule with smaller sectors spreads the available space over sectors less than others for an even distribution. Rule ties of sectors can be broken with favor to those sectors of patients with more vital signs transmitted or sourced. In other embodiments, sector sizes can favor patients based on a number of graphical illustrations or waveforms, number of numerics, a patient acuity such as derived from an Early Warning Score (EWS), or a combination.

    [0029] The computer device dynamically configures in real-time the display of vital signs in each of the patient sectors according to the assigned space. The assigned space for a sector includes header space and vital sign space. Header information is placed in the header space of the sector and vital sign information for one or more vital signs is placed in the vital sign space of the sector. The rules can further control which vital signs are displayed in each sector based on sector size.

    [0030] The display device 26 displays the configured display of the plurality of patients. The configured display includes the columns of the patient sector displays configured by the computer device. The display is updated or refreshed in real-time by the computer device as vital signs are received, and re-displayed by the display device.

    [0031] The computer device 18 can be a computer configured to receive the transmitted and/or sourced vital signs and connected to the display device 26. The computer device 18 can be connected to and participate in a network. The computer device includes one or more electronic processor or electronic processing device, one or more display devices which displays the monitored vital signs, menus, panels, and user controls, and can include at least one input device which inputs the healthcare practitioner selections, such as site preferences. The computer device can be a desktop computer, a laptop, a tablet, a mobile computing device, a smartphone, and the like. The computer device can include a network-based server computer. The disclosed space assigned and display configuration techniques are suitably implemented using a non-transitory storage medium storing instructions (e.g., software) readable by an electronic data processing device and executable by the electronic data processing device.

    [0032] The display device 26 as used herein encompasses an output device or a user interface adapted for displaying images and/or data. The display device can include a single display or dual display. Examples of the display device include a computer monitor, a television screen, a touch screen, Cathode ray tube (CRT), Storage tube, Bistable display, Electronic paper, Vector display, Flat panel display, Vacuum fluorescent display (VF), Light-emitting diode (LED) displays, Electroluminescent display (ELD), Plasma display panels (PDP), Liquid crystal display (LCD), Organic light-emitting diode displays (OLED), a projector, and Head-mounted display, and the like.

    [0033] With reference to FIGURE 2, an exemplary of a display 12 with dynamically changed variably sized patient sectors 32 is illustrated. Header information 40 is configured or placed in the header space 42 such as a bed location, a scoring indicator of an acuity score, such as the EWS, set alarm conditions, and the like. Graphical illustrations of the vital signs 44, such as waveforms are configured or placed in the variable sized vital sign space 46.

    [0034] Each vital sign includes at least one measurement of patient temperature, patient heart rate, patient blood pressure, or patient respiratory rate. A graphical illustration of each vital sign can include one or more measures. Each graphical illustration of a vital sign or waveform can be accompanied by one or more numerics 48. The numeric can be a function of the measures displayed in the waveform or include independent measures.

    [0035] Display space is assigned to sectors based on a minimum height of the graphical illustration of the vital sign. The vital sign can include a range of heights. For example, waveforms can be preferably displayed with a height of 100 pixels, but can be displayed with a minimum height of 80 pixels. Space for one waveform is assigned in one increment of 80 pixels or an increment of 100 pixels, but can be adjusted or resized to 80 pixels to fit within a sector. Space can be assigned based on neat sizes to provide a uniform appearance. Exceptions to neat sizes such as an ST Map can be assigned with different incremental or minimum sizes.

    [0036] In one embodiment, the order of the assignment of space for waveforms can be ordered. For example, with a first waveform with a first priority and a second waveform with a second priority, the assignment assigns space corresponding to the range of the first waveform before assigning space for the second waveform. Other embodiments include allowing selection of the second waveform before the first waveform if sufficient space is not available for the first waveform and the first waveform is larger than the second waveform.

    [0037] Space can be dynamically reassigned based on changes in acuity, changes in the monitored vital signs, or additional sourced vital signs or removed sourced vital signs. As more vital signs are transmitted and/or sourced for a patient, the added vital signs indicate a change in patient acuity and the computer device receives and configures the display with the added vital sign. As a vital sign is removed, e.g. no longer sourced, the computer device removes the vital sign from the patient sector and re-orders the assignment of space during a refresh accordingly. Small adjustments in space can be performed by the computer device based on the ranges of vital sign waveforms and remaining space. For example, with space assigned in a column to sectors and a remainder to 10 pixels, the remaining 10 pixels can be used to resize waveforms with the range of the waveform, expand header space, expand space between waveforms in a sector, and the like. The assignment of remaining space can provide a more uniform consistent appearance

    [0038] With reference to FIGURE 3 another exemplary of a columnar display with dynamically changed variable sized patient sectors 32 including a patient sector with differently sized vital sign displays is illustrated. Three graphically illustrated vital signs are shown 50, 52, 54. One vital sign graphically illustrated includes a ST map 54 or multi-axis portrait of one patient's ST segment values and trends derived from vertical (limb leads) and horizontal (chest leads) planes. The individual minimum height ranges or space size for each graphically illustrated vital sign can vary within a sector. The size of each sector can vary with the number and type of vital signs configured for display.

    [0039] With reference to FIGURE 4 one method of dynamically changing patient data displays is flowcharted. In a step or module 60, the display configuration requirements are determined. The number of columns of display, and the number of displays are determined. For example, the display can include a display for a single display or for a dual display device. The configuration requirements include the amount of available space to be assigned or unassigned space, e.g., number of pixels in a column of sectors.

    [0040] The vital signs for a plurality of patients are received in a step or module 62. The step can include sourcing of the vital signs, removing of sources, and/or adding vital signs for each patient. In a step or module 64, ordering requirements are determined for each patient display sector. The step can include receiving user specified minimum sizes, user specified data element, changes to the predetermined minimum sector sizes, user specified maximum sector sizes, EWS, other measures of patient acuity, etc. For example, attributes of the sectors with user-specified data elements are identified and updated. Sectors attributes are updated for each sector according to the rules which determine the priority order.

    [0041] In a step or module 66, space is assigned to the individual patient sectors from the unassigned space based on the priority order by the computer device. The step can include ordering the priority based on a set of rules. The rules can include assigning unassigned space first to sectors with a user-specified minimum size, second to sectors with one or more user-specified data elements, third to sectors less than a predetermined minimum sector size, fourth to smaller sectors, fifth to sectors with space assigned to all sourced vital signs, sixth to sectors with a user-specified maximum sector size and the maximum size assigned, and seventh to sectors with no sourced vital signs. The step can include constructing and/or modifying the heap data structure to identify the priority order of sectors for space assignment. The step can include priorities of vital sign displays by patient sector. For example, ECG and SpO2 waveforms are assigned prior to assigning space for other waveforms or graphical illustrations of vital signs. The step can include assigning space to sectors based on a minimum height of the graphical illustration of the vital sign included in the assigned sector. The step can include assigning space for header space and vital sign space in each patient display sector. The step can include variable sizes for vital signs included individual patient sectors.

    [0042] In a decision step or module 68, the assignment of space continues iteratively until the unassigned space is assigned. The iterative process dynamically configures in real-time for each patient an individually assigned patient sector display sized from available space for the display based on a priority order.

    [0043] The display is configured in real-time based on the assigned space to each sector in a step or module 70. The step includes placing header information in the header space of each sector and vital sign information in the variably spaced vital sign space of each sector. The vital sign information for each sector can vary with the number and type of vital signs. For example, one patient can include a multi-axis portrait (ST map) of the patient's ST segment values and trends derived from vertical (limb leads) and horizontal (chest leads) planes in addition to other vital signs displayed. The display of vital signs includes graphical illustrations for individual vital signs. Each graphical illustration of one vital sign includes a minimum height size. The individual vital sign information is updated in real-time as vital signs are received from the monitoring devices or sensors, e.g. updated waveforms and numerics. In a step or module 72, the configured display of the plurality of patients is displayed on the display device or devices.

    [0044] In a decision step or module 74, the process can be repeated. For example, as indications or notices of an additional vital sign are received or sourced, the process can be repeated which dynamically adjusts the display of the displayed vital signs with the additional sourced or received vital sign. In another example, as monitoring devices are disconnected, the vital signs are no longer sourced and the process repeats to dynamically remove the no longer sourced vital sign. The steps can be performed with a non-transitory computer-readable storage medium carrying software which controls one or more electronic data processing devices to perform the steps.

    [0045] In one exemplary embodiment, the acuity of each patient assigned to a column of sectors is determined. The rules are applied to the relative acuities to assign a relative height to each sector. The rules are applied to the relative height of each sector to assign which monitored vital signs are displayed. In assigning the relative height, the rules take into account minimum display heights, e.g. allocate relative height in increments of the minimum display height such that the sectors are not assigned heights which leave unusable space, due to the minimum height rules, in a plurality of the sectors.

    [0046] The monitored vital signs, including those that are not currently displayed are monitored to dynamically determined changes in the relative acuity, e.g. changes in the EWS. When the relative acuity changes the height of each sector is automatically reassessed and reallocated. Changes in allocated space automatically reassess and can change the display vital signs. Thus, when the acuity of one patient improves, some of the improved patient's sectors space can be reassigned to the sector space of one or more other patients. Similarly when a patient's acuity deteriorates, the rules can reallocate sector space and give the deteriorating patient more sector space. The rules of determining which vital signs are displayed in each sector may be based in part on the acuity score. For example, unstable vital signs can be given preference over stable or closer to normal vital signs.
