The globally optimized actions that result from this optimization process are applicable to many healthcare delivery scenarios including ACOs and other at-risk payment models, healthcare payers, healthcare systems and even individual hospitals that must optimize readmission rates and other outcomes.
  • One method of performing the foregoing optimization is to identify a set of events of interest, compute the health correlation graph for all events of interest for all patients in the system to be optimized and then compute a global figure of merit for the system.

Since each action locally optimizes the future path of the patient, the global optimum for all possible actions will include complicated interactions between actions and will result in an optimization strategy that improves outcomes at the global or system- wide level, rather than just the local optimization for a single patient for a single event of interest.
  • the properties of the system to be optimized can be represented as constraints in this analysis so that unrealizable actions are not suggested by the optimized model. This process results in an optimized action suggestion model.

  • gaps are presented as notifications to users in specific situations (specialty, care setting, patient comorbidities, etc.). Such notifications can include specific instructions for users for how to correct for the gap or discrepancy.
  • Gaps can also be rated or commented on as a way to improve the method and validate findings.
  • results from step 1274 are ranked based in information flow and friction in the system under investigation to optimize the impact of individual actions.
  • a patient state timeline is generated using ICD-9 concepts (shown in Fig. 5) (or other coding system, such as ICD-10, for time periods in which Medicare Advantage requires such coding system) in which each event is a clinical encounter that has been submitted for reimbursement.
  • Each state vector consists of multiple sections, corresponding to concepts found in encounter note sources, other clinical sources, and administrative and claims data sources.
  • the encoding for the HCC application is binary values indicating presence or absence of every concept in the coding system of interest (e.g., ICD-9).
  • sections for cross-terms between all the concepts in the state vector are also included, to create a final input vector X which contains both state and cross-term information.
  • the outcome value, V, for each encounter is the Medicare Advantage RAF score attributable to that visit.
  • the resulting vector, 'w' can be interpreted as the incremental contribution to the final RAF score from a particular appearance of a concept in a particular part of a patient's history.

  • FIG. 14 shows an example of the summary of the findings of Fig. 13.
  • Fig. 15 shows an example of further details of the opportunity findings of Fig. 13. The highlighted language of Fig. 15 is used as a link to an application for facilitating the single click gap presentation discussed above.
  • Multiplying these concepts by their weights in the w vector then gives a measure of the expected impact of the finding on the final RAF score. This measure is used to rank the HCC opportunity findings so that they can be acted on in an optimal order.

Abstract

L'invention concerne un moteur de navigation d'informations médicales (« MINE »). Dans certains modes de réalisation, le système calcule un vecteur de rencontre de patient courant pour une rencontre de patient courant, puis un vecteur de rencontre de patient optimal est calculé en supposant une rencontre de patient de meilleur cas en fonction des objectifs organisationnels. Le système est alors apte à calculer la différence entre la rencontre de meilleur cas et la rencontre de patient courant. Cette différence est utilisée pour calculer un gain correspondant à l'aide d'une matrice intelligente.
