This disclosure relates to representations and processing of medical data, and more particularly to, examples of graphical and textual displays of medical equipment data and data pertaining to a subject receiving treatment, monitoring or undergoing testing with electronic medical equipment.
Individual medical decision support platforms generally function independently without relying on performance optimizations derived from population specific data that is routinely collected. For example, decision support platforms may aggregate information into databases, but generally do not integrate the information or leverage knowledge gained to adapt and optimize therapy management rule sets and parameters to produce enhanced patient safety and patient outcomes.
A dashboard or user interface that adapts to user needs and provides information for treating patients in the presence of comparative analysis data with population performance under similar therapy rule sets and conditions may provide information useful to set alarms on outliers, and to flag outliers to staff for further investigation of inadequate response to therapy, for example.
Thus, an object of the present invention is the provision of a graphical user interface or dashboard system and methods that are useful to users or clinicians at various different levels in one or more healthcare facilities to monitor, manage and improve patient therapy conducted with electronic medical equipment.
This and other objects of the present invention will be apparent from the figures and the description that follows.
This disclosure may disclose, inter alia, systems and methods for a graphical interface including a graphical representation of medical data such as medical equipment data and data pertaining to a subject receiving treatment, monitoring or undergoing testing with electronic medical equipment. The systems and methods provide real-time, near real-time, and summarized or trended historical information and analysis tools to various levels of interested parties in a healthcare environment.
Any of the methods described herein may be provided in a form of instructions stored on a non-transitory, computer readable medium, that when executed by a computing device, perform functions of the method. In some examples, each function may represent a module, a segment, or a portion of program code, which includes one or more instructions executable by a processor for implementing specific logical functions or steps in the process. The program code may be stored on any type of computer readable medium, for example, such as a storage device including a disk or hard drive. In addition, methods described herein may include one or more operations, functions, or actions that can be performed in a sequential order, performed in parallel, and/or in a different order than those described herein.
Further embodiments may also include articles of manufacture including a tangible computer-readable media that have computer-readable instructions encoded thereon, and the instructions may comprise instructions to perform functions of the methods described herein.
The computer readable medium may include non-transitory computer readable medium, for example, such as computer-readable media that stores data for short periods of time like register memory, processor cache and Random Access Memory (RAM). The computer readable medium may also include non-transitory media, such as secondary or persistent long term storage, like read only memory (ROM), optical or magnetic disks, compact-disc read only memory (CD-ROM), for example. The computer readable media may also be any other volatile or non-volatile storage systems. The computer readable medium may be considered a computer readable storage medium, for example, or a tangible storage medium.
In addition, circuitry may be provided that is wired to perform logical functions in processes or methods described herein.
In still other examples, functions described herein may be provided within a graphical interface platform. In these examples, the graphical interface platform may include a graphical user interface (GUI). A processor may execute software functions to create a data layout, and additional charts or graphs, on a display device. The display device may be configured to illustrate the graphical user interface, which may be configured to enable a user to analyze medical data in a visual display and accepts user inputs/instructions to illustrate selected data in a desired manner.
The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the figures and the following detailed description.
In the following detailed description, reference is made to the accompanying figures, which form a part hereof. In the figures, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, figures, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.
This disclosure may disclose, inter alia, systems and methods for a graphical interface for providing medical data. The graphical interface may take the form of a graphical user interface (GUI), or of a real-time dashboard (RTD) software platform that is configurable on a user-by-user basis. The interface may be configured to provide contextually relevant data to a user. In some examples, the data may be based on a time frame (reporting intervals), on content (e.g., departments or clinical care areas of a hospital), prior usage patterns, or user type (e.g., pharmacist, nurse, physician, or quality assurance (QA) specialist). A base interval may include “real-time”, for example, for a hospital environment in which a clinician may oversee ongoing medication administration. As organizational rank of a user increases, time increments may be expanded to longer (historical) periods of time to provide a higher level summary.
In the context of this disclosure, the terms “real-time”, “near real-time” and “historical” are defined in relative terms. Real-time data is essentially current data that has been reported or communicated within about the past five seconds from the medical device, while near real-time data is current data that has been communicated within about the past five minutes, and historical data is previously reported data that was communicated at least about five minutes ago and more typically hours, days or longer ago. Historical data is a fairly easy concept to understand because such data was communicated a considerable time ago and therefore does not accurately reflect the current status of the medical device, nor the medication or patient associated with it. A user can analyze historical data for trends and to understand past activities, occurrences or performance, but would not believe the data to represent a current instantaneous status. However, the distinction between real-time and near real-time data is slipperier, blurrier, much harder to make, and depends greatly on the capabilities of the medical device, the communication network, and the graphical interface platform software to communicate, process, and populate all of the data on a particular graphic user interface screen or dashboard. Thus, the term real-time as used herein should be understood to more broadly include near real-time data as well, even when not specifically stated that way. Real-time data can be used for remote visual monitoring via the graphical interface platform to allow clinicians to locate medical devices, deliver medications to medical devices on a timely basis, and substantially immediately respond to alerts, alarms and other conditions of concern from medical devices or patients connected to the medical devices.
In some examples, the graphical interface platform may receive medical data and provide medical safety reporting capabilities including reporting of history data and real-time visual monitoring data. The graphical interface may be provided through an Internet interface, and can be made available to users on a restricted access basis.
In further examples, the graphical interface platform may be configured to identify potential problems and corrections to medical devices in operation while a reporting cycle is underway through visual representation of performance metrics.
The graphical interface platform may be a web-based user-by-user configurable real-time visual monitoring platform that provides contextually relevant and actionable data to the user. User adjustable filters can be provided to give the user an ability to drill down to identify potential actionable corrections as a result of alarms, alerts, infusion pump status, hard/soft limit overrides. Features include rules and/or algorithm engine, reporting, charting, drug library optimizer, and data aggregation of 3rd party HIT data sources, and dashboard settings, user access and privileges can be determined based on area of use (e.g., nursing, pharmacy, or biomed).
Referring now to the figures,
The medical server 114 may process received information in a number of ways, and thus, may provide a number of functions including localized monitoring and control for hospital-created clinical care areas (CCAs), specific drug libraries and dosing recommendations based on hospital guidelines and industry best practices, determine hard and soft dosing limits to provide medication safety at the bedside for clinicians, allowing them to practice according to established best practices while allowing flexibility and adjustment for special patient populations as needed. In addition, within hospital-created guidelines, real-time monitoring of medication administration at the bedside, and real-time verification of the “5-Rights” may be provided. In one example, the medical server 114 may include or be configured to operate according to the Hospira MedNet™ server suite software, provided by Hospira of Lake Forest, Ill.
The graphical interface platform 122 may be configured to present centralized (server-based) medical device data (e.g., infusion pump data) to provide actionable data for continuous quality improvement (CQI) purposes to increase medication safety at the bedside and potentially reduce or avoid ADE's (adverse drug events). An example for such actionable data is referred to herein as an Executive Scorecard. Executive scorecards allow the clinicians (administration or medication safety committee) to view the highlights of past medication administration (“top ten” in different categories). Viewing these data highlights provides the clinician the ability to investigate and target medications causing the most problems (such as the most alerts, edits and overrides) for the clinicians or patients at the bedside. The success of resulting changes and adjustments to clinical practice can be monitored on an ongoing basis by reviewing the Executive Scorecard data. The graphical interface platform 122 may configure data to report occurrences when safety software is not being used and/or an alarm or alert is triggered (allowing for real-time intervention by the clinician at the bedside), identify alarm, alert or limit overrides, identify trends in clinical practice (how doctors are prescribing medications and how nurses are administering them), configure and optimize a “drug library” and rule sets that govern acceptable parameters related to a given medication/concentration in a specific clinical care area or CCA, or provide decision support/optimization tools for “smart” IV pumps. The graphical interface platform 122 also provides the ability for the clinician to perform ad hoc data analysis with the “drill-down” capability of the interface.
The graphical interface platform 122 may provide a Local Clinical Decision Support System (LDSS), which may provide information for advanced management of therapy with optional event alerting and notification and automation of decisions (e.g., therapy modification or suspension). For example, a probabilistic model, including Bayesian Decision Trees, may be employed, based upon prior population data, to identify specific adverse drug events, such as hypoglycemia. The graphical interface platform 122 may provide a dashboard of information that displays information on population behavior of patients with similar classifications or undergoing similar clinical therapies by presenting population summaries and comparing individual patients with relevant population outcomes. The dashboard may allow population comparative analysis to refine local decision support performance or produce alarms/alerts that are meaningful with respect to indicating population outliers. Information can be presented in real-time and may be relevant to current therapies administration. Furthermore, dashboards can also be used to monitor measured diagnostics, therapy outcomes, and decisions of multiple therapies decision support systems for the same patient.
The medical server 114 may provide access to the graphical interface platform 122 in real-time and via a web-interface. The graphical interface platform 122 may monitor a patient from a perspective of applied therapy, and may further represent inputs (medication infusion), outputs (physiological response), and medication sensitivity in a graphical manner. As a result, clinicians can view results of therapeutic decisions in real-time and identify individuals whose states are improving or degrading.
Information provided by the graphical interface platform 122 may be representative of information from Enterprise Clinical Decision Support Systems (EDSS) that can collect and further analyze information generated by Local Clinical Decision Support Systems (LDSS), such as glucose management or coagulation management. The EDSS can leverage knowledge of patient population performance under various therapy protocols to optimize the therapy rule sets and/or probabilistic models of local decision support systems. Patient population subgroups can be determined from patients with similar classifications using multiple parameters or characteristic of that population, for example, age, height, gender, weight, ethnicity, risk profile and clinical indication.
Therapy rule sets and algorithms that adapt therapy initialization using population specific information can be optimized using information derived from databases representing the patient population with relevant classification. Therapy initialization parameters include dose volume, boluses, starting infusion rates, timing of diagnostics measurements and patient specific information (e.g., demographics, medication allergies, lab values, and therapy histories).
The graphical interface platform 122 can provide predictive capabilities based on statistical sampling, clinical modeling and trend analysis. Comparative analysis can be made between a specific patient performance under a therapy protocol and remaining patient population subgroup on the same protocol, and alarms or alerts can indicate if this patient is an outlier from the general population that was treated under similar conditions and protocols. Statistical tools used to indicate outliers include box-car plots, decision trees, probabilistic models, cluster analysis, and abstract factor analysis, for example. Outlier patients may simply be part of a special patient population or may indicate a medication contraindication, or an interaction between multiple medications preventing the therapy protocol from achieving its expected effectiveness. Patient and population information can be presented in real-time and may be relevant to current therapies administrated. Speed to response is critical in some therapy protocols, allowing for real-time intervention at the bedside, preventing ADE's, patient harm and potentially saving lives.
Quality metrics can be provided and may be indicative of effectiveness of the adopted therapy protocols and safety metrics can also be collected to ensure therapy protocols are also safe.
Compliance metrics can also be collected and assess clinical practice and adherence to established “best practice” therapy protocols; preventing adverse outcomes and ADE's. Process control metrics such as six-sigma P-charts can be provided and may be indicative of how reproducible the desired measured outcomes are, and deviations from expected targets and acceptable ranges may indicate need for quality initiatives.
In some examples, the graphical interface platform 122 enables integration of information from multiple sources relevant to multiple therapies administered on the same patient such as therapy outcomes, medication allergies, medication history, orders, decisions, diagnostic lab values, vitals, etc., to allow for comprehensive dashboards to monitor and diagnose overall patient status and coordinate interaction between individual therapy protocols administered for more informed decision making. Coordinating multiple LDSS may produce managed and synchronized decisions to prevent undesired interactions and adverse events, optimize therapy decisions and allow for integration and documentation of information on sources of variability to an expected outcome of a particular LDSS.
Dashboards can further function to integrate information from multiple data sources, across heterogeneous hospital networks and information systems, and may aggregate and normalize databases and information, for example, such as combining multiple allergy definitions and vocabulary into a single standard definition (e.g., since medical terminology and uses are predominantly not standardized). A reference vocabulary database can be used along with a natural language processing engine to determine a context of use of terminology and eligibility for substitution, and the dashboard may automate selection of an appropriate reference vocabulary.
Dashboards can be further used to measure frequency of alerts, and alert loading per clinician, as well as workload per clinician, and average length of stay for patients as measures of quality of care. Other quality metrics can be designed to provide close to real-time monitoring of quality of operations. As an example, the dashboard may provide a patient event monitor that generates an alert when a change in patient condition has been detected on a basis of estimated internal control parameters (e.g., estimated medication sensitivity, compartmental volumes, and opioid efficacy). In some examples, the dashboard provides a model of the patient and detects a change in a condition of the patient on the basis of estimated internal parameters rather than observed measurements (e.g., vitals and labs).
In some examples, the graphical interface platform 122 may be configured to process information exchange between a plurality of local devices performing local decision support, and may benefit from population aggregated data to produce optimizations to the local decision support as well as indicate comparatively outliers from mainstream population outcomes as early alarms for need for intervention.
The interface 202 may be a web-based interface enabling access by users via the Internet. Information provided to the display 210 may be based on a role-based view to enable context-relevant details (e.g., by discipline and detail level), and may provide user-specified customization of displayed data in a view.
The rules engine 204 may be configured to generate actionable notifications based on user-defined thresholds or internal decision models (e.g., decision trees, artificial neural network, Markov model, probabilistic networks, etc.) and route them to the user's preferred communication device (e.g., pager, cell phone, PDA, workstation, etc.). The reports and charting engine 206 may be configured to run ad hoc reports based on user-defined preferences. The message/alert engine 208 may be configured to route actionable notifications by email, pager, mobile phone, SMS, nurse station, central operator, etc., based on user preferences.
The graphical interface platform 200 may provide real-time visual monitoring of safety and operational metrics, real-time alerts that are pushed out to clinicians to enable immediate response, and trending/early warning indicators to identify opportunities for improvement. Information that is provided to the display 210 can be filtered based on a user customization, such as for nursing, pharmacy, biomed, risk management/quality, information technology, etc. Data from a number of servers (e.g., shown in
Furthermore, data may be output in a form of executive scorecards to allow c-level (Chief Information Officer, Chief Executive Officer, Chief Nursing Officer, etc.) hospital leaders to review actionable data, assess and leverage metrics and understand hospital performance as related to medication safety. Hospitals may produce scorecards “on-the-fly” to identify clinical trends in medication administration, deviations from established “best practices”—providing the needed focus for corrective interventions, assessing the effectiveness of such interventions in an effort to improve medication safety at the bedside and prevent ADE's and potential patient harm.
Each of the rules engine 204, the reports and charts engine 206, and the message/alert engine 208 may receive a set of parameters related to therapy objectives for a patient and thresholds for all input/output and calculated variables. Each of the rules engine 204, the reports and charts engine 206, and the message/alert engine 208 may include an input module that receives the infusion information and diagnostic response, a calculation module that models the input/output or I/O relationship between the medication infusion and diagnostic response, a database for accumulating calculated parameters specific to the calculation module, a decision module that monitors inputs, outputs and calculated parameters and detects changes in any or all of the three categories, and an alert capability that is set when a change has occurred.
The calculation module may include a single multivariate model, such as used with time varying parameters or probabilistic network, that are adjusted based upon data and clinician input using maximum likelihood optimization, structured optimization (e.g., genetic or hill-climbing algorithms), an extended Kalman filter, Bayesian estimator based upon input/output data. The calculation module may also include a mixture of single models operating in parallel. The individual models are weighted or prioritized based upon prediction error. In addition the models can be used for prediction and analysis of possible outcomes. The calculation module may further include other multiple models, in which a group of static models can be used to identify patient responses and the group of models with a lowest prediction error through time can be selected for analysis.
The graphical interface platform 200 may be configured to model patient therapy and response dynamics and detect a change in condition of the patient on the basis of internal parameters. The rules engine 204, the reports and charts engine 206, and the message/alert engine 208 may provide predictions of future physiological variables and risk metrics for display on the dashboard. The graphical interface platform 200 may be further configured to model therapy alternatives and select an objective that best suits the therapy objective. Therapy objectives can be selected based on time to reach targets or safety, such as avoiding medication interactions, optimizing medication delivery profiles, minimizing the risk of an adverse outcome or reducing cost of therapy.
The graphical interface platform 200 may be configured to operate on a computing device. Alternatively, a computing device may be configured to provide the graphical interface platform 200. The computing device may be a personal computer, mobile device, cellular phone, tablet computer, etc., and may be implemented to provide the graphical interface platform including a graphical representation as shown in any of
A user name and password may be required to access the dashboard program. If the password or user is not recognized based on a database of eligible users, the user cannot continue to the next screen. Based on the user identification numbers, users can be assigned various privileges and rights, which allow access to view various data with various granularities. For example, based on organizational hierarchy, levels and qualifications of the user (e.g., bedside nurse versus facility supervisor/charge nurse versus Chief Nursing Office or CNO versus Pharmacist), different types and details of relevant information may be shown. The type and amount of information may be customizable per user, user type, or privilege status.

An example screen shot of the “Infusion (Graph-Advanced)” tab is shown in
Each line-item representation of an infuser under a specific clinical care area indicates in real-time the current status of the pump, container information, and battery information. A number of bag/container icons are used to indicate how many containers are being administered by the infusion pump. By way of example, for a three-channel infusion pump system that can deliver from two containers per channel in an alternating sequence or simultaneously, up to six total bags/containers are shown in

Events shown within the “best practice” range typically indicate the clinician did not encounter an alert when programming the infusion device. The yellow “evaluate” category would signify soft limit alerts and the red “investigate” category signifies hard limit alerts. Filters (such as CCA and medication) can be applied.
Users with permission access rights may enter alphanumeric type search criteria in the search field located in the upper right portion of the interface, e.g., as shown in the illustration in
The example interfaces shown in
In some examples, as shown within any of
Within examples described herein, a graphical interface platform is provided that receives data and provides reports in real-time and on a historical or trended basis to users. The graphical interface may be configured to determine medical devices operating outside of protocol, and may be configured according to filter parameters. For example, ad-hoc research may be performed by configuring filters of the graphical interface to determine operation of devices, administration of medications, etc. As a specific example, a user may research for trending in the past twenty-four hour period for usage of the drug heparin within a certain unit of a hospital. With regard to operating outside of protocol, a user can determine top ten errors or adverse events within a hospital.
The graphical interface may be configured to process received data to provide trending in real-time, such as nursing function oversight or why a dose of medication was prescribed when outside certain protocols. In examples, the interface may enable hospital personnel to readily identify infusion pumps that are operating outside of protocol or to identify practice trends regarding the use of pumps.
The graphical interface further enables CQI (continuous quality improvement) reporting, providing actionable data to support the caregiver at the bedside, improve medication administration safety and to avoid ADE's (adverse drug events) and potential patient harm. The graphical interface supports the user in identifying opportunity for drug library optimization.
The graphical interface may be further configured to provide notifications for any number of indicators, alerts, and alarms. The notifications can be provided in an escalated manner, such as to initially provide the notification to the bedside nurse, then to the charge nurse, then to the house or facility supervisor, etc.
The graphical interface may be further configured to enable searching for data, such as to search for a specific medical device and return a location of the device, information associated with use of the device, etc. The graphical interface may receive data from a number of systems in a hospital, and provide information related to census and patient acuity, ensuring the correct distribution and availability of infusion devices, etc. Further, the graphical interface may be configured to provide a two-dimensional or three-dimensional map of where a medical device is located. The map can include graphical representations of the medical devices in a particular area or volume of space. The graphical representations can be relatively simple geometric shapes such as dots, triangles or rectangles representing different medical devices or they may be digital or holographic images of the medical devices. As described herein the graphical representations of the medical devices on the map can be equipped with colors, text, symbols or other display characteristics that provide additional information, including but not limited to battery/AC status, alert/alarm status, no connection status, etc.
The graphical interface may be accessible via the Internet, an internet or other web-based application. The graphical interface may be configured as shown in any of the examples described herein to provide a graphical representation of medical devices in which the graphical representation indicates information about the medical devices using color, icons, location of graphics, etc.
Within examples described herein, a graphical interface platform is provided that illustrates a number of types of information. Components of the graphical interface platform may be customizable in a drag/drop manner, such that components of the graphical interface platform include modules for display. For example, drag-and-drop includes action of (or support for the action of) selecting an object and dragging the object to a location in the interface or onto another object. Objects to be selected may include components of the graphical interface platform. The components of the graphical interface platform include any of the illustrations within
It is further contemplated that the dashboard or graphical interface platform can be arranged to be customizable or configurable by the user to define the screens and screen content they find most relevant or helpful in their role. It should also be understood that while a “Top 10” approach has been taken on some screens, one or more approaches selected from a top 3, 5, 15, 20, 25, 50 or 100 approach could be implemented instead or as well.
It should be understood that arrangements described herein are for purposes of example only. As such, those skilled in the art will appreciate that other arrangements and other elements (e.g. machines, interfaces, functions, orders, and groupings of functions, etc.) can be used instead, and some elements may be omitted altogether according to the desired results. Furthermore, many of the elements that are described are functional entities that may be implemented as discrete or distributed components or in conjunction with other components, in any suitable combination and location.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art.
