Patent number: 11735026Abstract: In some examples, systems, methods, and devices are described that generate contextual suggestions for patients. Generation of the contextual suggestions is triggered by certain events performed by a medical professional with respect to a patient (e.g., updating a patient record). The contextual suggestions are related to addressing health conditions of the patient and represent tasks or considerations which the medical professional should be made aware. The contextual suggestions are generated in a way that is considerate of patient context, medical professional context, and contexts of similar patients. The contextual suggestions can be presented to the medical professional for selection and execution.Type: GrantFiled: February 1, 2022Date of Patent: August 22, 2023Assignee: C/HCA, INC.Inventors: Christian Krayer, William Michael Gregg, Thomas Andrew Doyle, Paul Brient, Jim Najib Jirjis, Karl Bradley Kehler, Jonathan Perlin, Paul Martin Paslick, Edmund Jackson, Sarah Hume Buta, Erin S. Jospe, Umesh P. Phirke, Steven V. Manoukian, Vincent Doyle, III, Wesley Boles, Ravi S. Chari

Patent number: 11237937Abstract: Systems, methods, and machine-readable media are provided to facilitate controllable parameter modification of system components based on monitoring indicators of a caliber of process performance. A set of cases is identified from amongst the plurality of cases, the set of cases having similar temporal identifiers and a same type of process performance. A population check-point statistic is generated based on the check-point indicators identified in the set of cases. A first result that indicates whether a first criterion is met is determined based on the population check-point statistic. A second result that indicates whether a second criterion is met is determined based on a check-point indicator. When the first criterion or the second criterion is not met, one or more transmissions are to alert a remote device and to facilitate causing a system component to make a change to a controllable parameter to influence a corresponding check-point.Type: GrantFiled: October 2, 2020Date of Patent: February 1, 2022Assignee: C/HCA, Inc.Inventors: Ravi S. Chari, Jenny F. Barber, Dawn A. Winans

Patent number: 10055547Abstract: A quality of medical care can be estimated based on factors such as a mortality rate or complications rate. However, by this point, poor care may have already reached its consequence. In some embodiments, characteristics pertaining to a care experience are analyzed to identify those predictive of a health result. The identified characteristics may include ones that depend on care factors, such that they are not, alone, easy to manipulate. Those characteristics can then be monitored, and unsatisfactory characteristics can be addressed.Type: GrantFiled: June 13, 2014Date of Patent: August 21, 2018Assignee: HCA Holdings, Inc.Inventors: Ravi S.

Publication number: 20110295125Abstract: A method for detecting death process of a cell or tissue of a living subject. In one embodiment, the method includes the steps of illuminating the cell or tissue of the living subject with a coherent light, collecting fluorescent light returned from the illuminated cell or tissue of the living subject, identifying a NAD(P)H peak of a spectrum of the collected fluorescent light with a wavelength, ?peak, and obtaining the intensity of the NAD(P)H peak of the spectrum of the collected fluorescent light substantially corresponding to the wavelength ?peak. These steps are repeated at sequential stages until the intensity of the NAD(P)H peak of the spectrum at a current stage is less than the intensity of the NAD(P)H peak of the spectrum at an earlier stage immediately prior to the current stage so as to detect death process of the cell of the living subject at the current stage using the intensity of the NAD(P)H peak of the spectrum.Type: ApplicationFiled: May 26, 2011Publication date: December 1, 2011Applicant: VANDERBILT UNIVERSITYInventors: Wei-Chiang Lin, Steven A.

Patent number: 7979107Abstract: A method for differentiating malignant in vivo liver tissues from normal in vivo liver tissues of a living subject includes the steps of: (a) illuminating a first area and a second area of in vivo liver tissues of the living subject with a first excitation light, (b) measuring an intensity of fluorescent light emitted from each of the first area and the second area of in vivo liver tissues in response to the first excitation light as a function of wavelength so as to obtain a first and a second fluorescent spectra, respectively, (c) illuminating the first area and the second area of in vivo liver tissues with a second excitation light, (d) measuring an intensity of diffuse light reflected by each of the first area and the second area of in vivo liver tissues in response to the second excitation light as a function of wavelength so as to obtain a first and a second diffused reflectance spectra, respectively, and (e) identifying one of the first area and the second area of in vivo liver tissues as malignant livType: GrantFiled: August 6, 2009Date of Patent: July 12, 2011Assignees: Vanderbilt University, Cleveland Clinic FoundationInventors: Wei-Chiang Lin, Steven A.
