The i2b2 Health Outcomes Monitoring and Evaluation (HOME) Cell allows users to\u00a0evaluate health outcomes over time without direct programming.\u00a0The HOME Cell uses the existing i2b2 framework (queries, ontologies, data) and drag-and-drop software components to allow users to model a vast number of exposures (including interventions such as medications or tests) \u00a0against an equally large number of outcomes accounting for complex temporal relationships and stratified by sub-populations. \u00a0The process typically follows the following 8\u00a0steps.<\/p>\n

    \n
  1. \u00a0Define a base query using the i2b2 Query Tool<\/a>\u00a0(not the HOME Cell). \u00a0This query needs to include all possible patients but needs to include everyone who will ever be included in a denominator group. \u00a0It should be the smallest possible number to improve query efficiency. \u00a0For example, a base query of everyone who has ever had diabetes could be used to support all HOME Cell queries related to patients with diabetes.<\/li>\n
  2. \u00a0Open the i2b2 HOME Cell.<\/li>\n
  3. \u00a0Apply the base query to the new HOME Cell query within the denominator tab<\/a>.<\/li>\n
  4. \u00a0Use Constraints<\/a> (Age, Occurrence, Value) to define the denominator population.<\/li>\n
  5. \u00a0Use Constraints to define the numerator<\/a>\u00a0population (people from the denominator with the target outcome).<\/li>\n
  6. \u00a0Specify (optionally) sub-populations (strata<\/a>) to evaluate the target outcomes which are, like the base query, a previously created i2b2 Query Tool.<\/li>\n
  7. \u00a0Define the reference interval<\/a> and date range.<\/li>\n
  8. \u00a0Execute the query!<\/li>\n<\/ol>\n

    After a HOME Cell is successfully completed, the completed data can be found in the data tab<\/a>\u00a0which can be exported as a spreadsheet or copied.\u00a0The data will also be presented in a graphical format in the Graph tab, which can easily be exported as a static file image. \u00a0Each step is described in more detail within this section.<\/p>\n","protected":false},"excerpt":{"rendered":"
