COG170 Slicer Dicer Exam Questions With Correct Answers
What is a population? - ANS-W¥wW The population defines the data that will be used by the data model. Criteria can be added to further narraw the data set. SlicerDicer respects user securily in what ways? - ANS-WW1. Users will not have access to every data modcl in the system. Each data modcl isavailable to only a subsct of users, 2, When a user builds and slices populations, all of the data retrieved is implicitly filtered by Service Arca security. 3. Mosl users will not be able to view dala aboul individual members o! a population A scheduler wants a population that shows how many appointments there are today with a status of 'Scheduled,' They want to reference this throughout the day to keep track of how many appointments are left to check in, Could this be done in SlicerDicer? Why? -— ANS-WWNo, SlicerDicer does not contain today's data, so a list of scheduled appointments wouldn't change throughout the day. A user wants a list of surgical cases scheduled in the next weck grouped by procedure, They will reference this list at the start of cach week to audit room and staff usage. Could SlicerDicer meel this need? Why? — ANS-VWW Yes. Even though the list has to include future cases, these cases were scheduled in advance, and all such surgerics scheduled at least a day carlicr will be displayed. True or alse: SlicerDicer sessions are the best option for KP] (key performance indicators}. - ANS-WWNo KPIs «Key Performance Indicators} need to be standardized for all consumers. Since SlicerDicer is designed to let every user adjust and manipulate their visualization of the underlying data, il is not ideal Jor this type of report. Instead, we use Dashboard Metrics as our primary tool for distributing KPIs to consumers. Data Model — ANS-WWOne SlicerDicer Data Model cansists af a set of dala thal has been curated with a pre-built set of available filtc unique data models as well. Epic releases many data models, but an organization can create their own SlicerDicer respects user security in several ways: — ANS-WW 1. Users will not have access to every data model in the system, Hach data model is available to only a subsct of users. 2, When a user builds and slices populations, all of the data retrieved is implicitly filtered by Service Arca security. 3. Most users will not be able to view data about individual members of a population. SlicerDicer and large data sets - ANS-WWSlicerDicer retrieves its data from the Caboadle database. This means it can filter and display large data sets without affecting your production database, Chronicles, With the ability to modify your date range and aggregate over weeks, months, or even years, SlicerDicer can be the primary resource for discerning long-term trends across your organization, SlicerDicer and small data sets —- ANS-WWSlicerDicer can also be a powerful tool for follawing up on specific, small scts of records, After a user narrows down their population to the records they need, they can view the data at the line level or export the data to Reporting Workbench where the population can be acted on directly. add new criteria by clicking Browse in their Population to sclect from the available criteria, The list of ayailable criteria for a data model is defined by SlicerDicer Milters, By default, slicing will always include a slice for - ANS-~WWv "nonce of the above" comparing your sliced portion of the population to the rest of the population. To disable this, click Settings and clear the box for Add “none of the above" or "no value" to slices by default, After selecting a SlicerDicer lilter to slice on, the user can: —- ANS-WWSpccify what yalues for the SlicerDicer Filter should cach get their own slice Grab the top 10 Grab the battom 10 Grab the top or bottom N records vhere N is user specilied} Measures — ANS-VWvWMecasures determine what function aggregates the data, This ean be thought of as the number at the top of the bar in a verlical bar graph. Once again, the SlicerDicer Filters used when building criteria or slices are the same as those available when choosing a measure. Any time a user wants to see their data expressed as: Goals and Thresholds - ANS-WWUse Thresholds to assign ranges of valucs ta a certain color. Bars whose valuc for that measure fall within the range will be the chasen color, One session can contain up lo 15 thresholds ranges. Use Goals to assign a single yalue to your measure, Your visualization will display a line at that value. One session can contain up to 15 goal values. Goals and Thresholds appearance in slicerdicer — ANS-WW Goals will appear as a linc for bar graph and line graph visualizalions. In a pie or ring chart, a goal appears as ils own separate wedge. Thresholds only appear in bar and line graph visualizations. Neither appear in stacked bar graph visualizations. Custom Measures — ANS-WWI[ you create mulliple measures, you can choose which of them to use in your Visual Options, or you can combing them into a new custom measure. Date Range in SlicerDieer — ANS-¢VWSlicerDicer always considers data within a date range specified in the population header . Users can change the start and end dates of this range in the Dates card. They can also slice the date range into sections like day, month, and year to trend their data aver time. The date range does not alfect cerlain SlicerDicer Filters. These only reflect on the most recent yaluc stored in an item and are labeled as Last Stored, Users will sce the following message when they use these so they understand how the date range won't change their results. Why aren't SliceDicer session not for KPI (key performance indicators) reporting? — ANS-WWVKDPIs «Key Performance Indicators} need to be standardized for all consumers, Since SlicerDicer is designed to let every user adjust and manipulate their visualization of the underlying data, it is not ideal for this type of report. Instead, we use Dashboard Metrics as our primary tool far distributing KPIs to consumers. To access more powerful and complex ways to use a criterion, click on its customization button. The button appears as a cogwhecl on the criterion . Options for this criterion incude: . 7 ANS-WWvAdd sequential criteria, which returns records where onc criterion precedes another Add overlapping crileria, which returns records where all criteria are met simultancously Specify date range, which allows cach criterion to use its own date range Specify age at time of event, which allows the addition of an associated age in ycars tied to a single event criterion True or False, Criteria always defaults to being EXCUSIVE, not INCLUSIVE — ANS— Vv False Criteria default lo being inclusive, This means they only include results for wham the criterion is truce, If you wish ta instead create a population for whom the criterion is false, you can change from inclusive to exclusive cither when adding the criterion initially, or by clicking the customization button €}. (cogwhcel button) Logical operators — ANS-WW Clicking the logical operators between criteria can flip them between AND and OR to change how they are evaluated. In addition, a user can use the Advanced Logic bulton to write their own logical expression combining the different criteria, What is the only place that users can sce PHI data? - ANS-~WvThe “Detail Table" yiew under Visual Options. Why use Sequential Criteria? - ANS-WvW Using sequential criteria, you could find all patients with a knee replacement followed by a physical therapy encounter, or find all office visits followed by an ED encounter. Why use Overlapping Criteria? - ANS-WW Using overlapping criteria, you could find all patients who were diagnosed with influenza on the same day that Walt Whitecoat was their provider, instead of finding all patients who had influenza in the past year and also had Walt Whitecoat as their provider in the past year. Why used Criteria—Specific date ranges? — ANS-WWv Using criteria-specific date ranges, you could find all patients with a cancer diagnosis in the last year who have a visit scheduled in the next month.
