LOS Comparison - Facility CareScience

This analysis enables you to evaluate the LOS outcomes for a defined population. Use this analysis to identify the top MS-DRGs with opportunity for improvement.

Select Population Tab:

There are 3 required prompts that you must select before running this analysis.

Required Prompts:

  • Facilities
  • Time (1 year is selected by default.)
  • Inpatient/Outpatient (Inpatient is selected by default. You should not select Outpatient for this analysis because risk-adjusted metrics are calculated for inpatients only.)

Optional Prompts:

  • Diagnoses (ICD-10)
  • Procedures (ICD-10)
  • Inlier/Outlier
  • Patient Types
  • Patient Demographics
  • Patient Origination
  • Patient
  • Practitioners
  • Patient Visits
  • Resources
  • Facility Payers
  • Standard Primary Payers
  • Standard Secondary Payers
  • Patient Qualifications

Set Up Analysis Tab:

Row Header Prompt

  • MS-DRG is selected by default. However, you can select any attribute(s) you want.

Expected Values on CareScience Analyses

CareScience analyses have two risk-calculation modes for the Expected value: Standard Practice and Select Practice. Standard Practice is the default, but you can change modes in the Page-By. Because the selected risk-calculation mode determines the Expected value, when you change modes, all the metrics based on the Expected value change as well. For more information, see Standard and Select Practice.

Default Metrics

The following metrics appear in the grid when the analysis returns:

  • Total Cases - All cases that qualified for the analysis.
  • Outcome Cases - The number of cases for the LOS outcome that qualified for risk adjustment. Based on the Outcome Case methodology, some cases may not qualify for risk adjustment.
  • Geometric Observed - The geometric mean length of stay (LOS) for the LOS Outcome Cases.
  • Geometric Expected - The expected value for the Outcome Cases, calculated using the CareScience Analytics risk-adjustment methodology and the geometric mean.
  • Geometric O/E - The Observed value divided by the Expected value. Less than 1 = performing better than expected. Greater than 1 = performing worse than expected.
  • Geometric Variation - The Observed value minus the Expected value.
  • Geometric SS - Asterisks display only if the Variation is statistically significant. The number of asterisks indicates the confidence level that the outcome's variation is not due to chance: 1 asterisk = 75%, 2 asterisks = 95%, 3 asterisks = 99%. Green asterisks = the outcome’s variance is statistically better than expected. Red asterisks = the outcome’s variance is statistically worse than expected. Total lines do not have values for Statistical Significance.
  • Opportunity (Geo LOS) - Variation multiplied by the LOS Outcome Cases. There must be at least one opportunity day for a value to display. Opportunity days are rounded to the nearest whole number.

Metrics in Report Objects

Report Objects allows you to add metrics to the grid. Click the button in the Tools toolbar to see the metrics in Report Objects. You can drag-and-drop the following metrics on the grid for this analysis:

  • CMS HAC Cases After Admit - The number of patients with at least one CMS Hospital Acquired Condition (HAC) after admission.
  • Arithmetic Expected -  The expected value for the Outcome Cases, calculated using the CareScience Analytics risk-adjustment methodology and the arithmetic mean.
  • Arithmetic Observed - The arithmetic mean length of stay LOS for the LOS Outcome Cases.
  • Arithmetic O/E - The Observed value divided by the Expected value. Less than 1 = performing better than expected. Greater than 1 = performing worse than expected.
  • Arithmetic Variation - The Observed value minus the Expected value.
  • Arithmetic SS -  Asterisks display only if the Variation is statistically significant. The number of asterisks indicates the confidence level that the outcome's variation is not due to chance: 1 asterisk = 75%, 2 asterisks = 95%, 3 asterisks = 99%. Green asterisks = the outcome’s variance is statistically better than expected. Red asterisks = the outcome’s variance is statistically worse than expected. Total lines do not have values for Statistical Significance.
  • Opportunity (Arith LOS) - Variation multiplied by the LOS Outcome Cases. There must be at least one opportunity day for a value to display. Opportunity days are rounded to the nearest whole number.
  • Total Days - The total number of days for the LOS Total Cases.
  • Total Days for ALOS Outcome Cases - The total number of days for the LOS Outcome Cases.
