Patent number: 11862310Abstract: A system, method, and computer-readable media are provided for facilitating clinical decision making, and in particular, decision making based on a third party's clinical situation by determining and providing useful, up-to-date information, such as patient-related information to a decision maker. In one embodiment, a user first identifies an information item concerning a patient. Based on that item, a set of related information items is determined and prioritized, and a reference pointer, which identifies the set of related information, is generated. The reference pointer is communicated to the user's mobile device. Subsequently, the user's mobile device requests information from the set of information items associated with the reference pointer, and provides information authorization information. Following authentication of the user's credentials, updates of information from the set of information items may be communicated to the user's mobile device as they become available.Type: GrantFiled: March 7, 2023Date of Patent: January 2, 2024Assignee: Cerner Innovation, Inc.Inventor: Douglas S.

Patent number: 11857477Abstract: Technologies are provided for determining a likelihood or risk of a human patient for developing pressure injury based on patterns of movement by the patient determined using a specialized measurement support surface. Some embodiments automatically ascertain whether patterns of movements of a human subject, whose weight is supported on the support surface, exhibit sufficient frequency and variability of activity such as will confer either certain health benefits or expose the individual to certain health risks, such as development of pressure ulcers in the load-bearing skin and soft tissues. If the determined patterns manifest such features associated with benefits or risks, then a notification may be provided for the patient to move; for instance, to the patient or a caregiver. In some embodiments, a notification may be provided at an irregular time intervals within-day intervals.Type: GrantFiled: September 18, 2019Date of Patent: January 2, 2024Assignee: Cerner Innovation, Inc.Inventor: Douglas S.

Patent number: 11853707Abstract: Technologies are provided for determining deficiencies in narrative textual data that may impact decision-making in a decisional context. A candidate text document and a reference corpus of text may be utilized to generate one or more topic models and document-term matrices, and then to determine a corresponding statistical perplexity and probabilistic coherence. Statistical determinations of a degree to which the candidate deviates from the reference normative corpus are determined, in terms of the statistical perplexity and probabilistic coherence of the candidate as compared to the reference. If the difference is statistically significant, a message may be reported to user, such as the author or an auditor of the candidate text document, so that the user has the opportunity to amend the candidate document so as to improve its adequacy for the decisional purposes in the context at hand.Type: GrantFiled: October 13, 2021Date of Patent: December 26, 2023Assignee: Cerner Innovation, Inc.Inventor: Douglas S.

Patent number: 11854699Abstract: A system, methods, and computer-readable media are provided for the automatic identification of patients having an elevated near-term risk of pulmonary function deterioration or respiratory distress. Embodiments of the invention are directed to event prediction, risk stratification, and optimization of the assessment, communication, and decision-making to prevent respiratory events in humans, and in one embodiment take the form of a platform for wearable, mobile, untethered monitoring devices with embedded decision support. Respiratory information is obtained over one or a plurality of previous time intervals, to classify a likelihood of events leading to an acute respiratory decompensation event within a future time interval. In an embodiment, the risk prediction is based a plurality of nonlinearity measures of capnometry information over the previous time interval(s), and the risk for an acute respiratory decompensation event determined using an ensemble model predictor on the nonlinearity measures.Type: GrantFiled: December 5, 2019Date of Patent: December 26, 2023Assignee: Cerner Innovation, Inc.Inventor: Douglas S.

Patent number: 11803767Abstract: Systems, methods, and computer-readable media are provided for facilitating clinical decision making by directing the emission of computer-generated health-care related recommendations towards contexts in which the recipient will likely find the recommendations salient and will likely welcome them and act upon them. ‘Uptake’ of computer-generated recommendations for diagnostic tests or therapeutic interventions is thereby substantially increased, and ‘alert fatigue’ is substantially decreased. Embodiments of our technology overcome certain drawbacks associated with the prior art by providing a means for ascertaining which decision-support recommendations are likely to be favorably considered by the recipient and acted-upon (recommendation ‘uptake’). System and method embodiments for providing a predicted probability of user uptake of a context-specific system-generated recommendation patient are disclosed herein and for applying that information to decide whether or not to emit the relevant recommendation.Type: GrantFiled: June 1, 2020Date of Patent: October 31, 2023Assignee: Cerner Innovation, Inc.Inventors: Douglas S.

Patent number: 11763821Abstract: Various tools are disclosed for providing assistive or augmentative means to enhance the fluency and accuracy of persons having speech disabilities. These technologies may automatically ascertain and dynamically improve the accuracy with which automatic speech recognition (ASR) systems recognize utterances of persons having impaired speech conditions. In an embodiment, digitized audio information about a speaker’s utterance is processed to determine a set of candidate words matching the utterance. From these candidate words, a set of concepts is determined using a finite state machine model. A pictogram representing each concept is identified and presented to the speaker so that the speaker may select the pictogram corresponding to the best match of his or her intended meaning associated with the utterance. An action corresponding to speaker’s selection then may be performed. For example, displaying or synthesizing speech from textual information describing the selected concept.Type: GrantFiled: June 27, 2019Date of Patent: September 19, 2023Assignee: Cerner Innovation, Inc.Inventor: Douglas S.

Patent number: 11751816Abstract: A cusp catastrophe approach is provided for predicting an occurrence of an ischemic myocardial event (e.g., acute myocardial infarction) for a human patient based on measurements of a vital sign via one or more sensors. The one or more sensors may comprise a user-wearable device. A cusp catastrophe model is used to process the vital signs measured. In some aspects, the cusp catastrophe model is used for processing a time series constructed from the vital sign measurements. In aspects, the time series may also include historical vital signs of the patient stored in an electronic health record system. A likelihood of the patient experiencing a myocardial ischemia occurrence is determined based on an output of the cusp catastrophe model satisfying a threshold. Based on the likelihood determined, a response action is initiated.Type: GrantFiled: January 27, 2022Date of Patent: September 12, 2023Assignee: Oracle International CorporationInventor: Douglas S.

Patent number: 11749404Abstract: An improved decision support tool is provided for detecting and treating human patients at risk for having (or developing) venous thromboembolism VTE. The tool determines a quantitative probability of VTE by utilizing a smart sensor based on a particular machine-learning model for detecting specific biomarkers determined to be related to VTE. In particular, a quantitative probability of VTE may be determined via a model based on interrelationships between multiple components of the human body's complement cascade and their coupling to coagulation processes. In one aspect, a quasi-Dirichlet distribution “mixture” relationship between total hemolytic complement (CH50) activity and complement protein C3 levels is employed as part of a smart sensor and decision support tool to provide predictive, diagnostic, and prognostic applications and for guiding prevention and treatment of acute VTE. Where the smart sensor determines a risk for VTE, then the decision support tool may initiate an intervening action.Type: GrantFiled: October 8, 2019Date of Patent: September 5, 2023Assignee: Cerner Innovation, Inc.Inventor: Douglas S.
