LOS Comparison - Peer CareScience

This analysis evaluates LOS outcomes for a defined population and compares them to the same outcomes in a selected peer group. Use this analysis to measure your LOS outcome performance to that of your peers.

Select Population Tab:

There are 4 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.)
  • Peer (You must choose at least five facilities and comply with the External Peer Methodology in order for peer data to appear on the analysis.)

Optional Prompts:

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

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:

  • Facility 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.
  • Facility Geometric Observed -The geometric mean length of stay (LOS) for the LOS Outcome Cases.
  • Facility Geometric Expected -The expected value for the Outcome Cases, calculated using the CareScience Analytics risk-adjustment methodology and the geometric mean.
  • Facility Geometric Variation -The Observed value minus the Expected value.
  • Facility 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.
  • Facility 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.

The following metrics represent the aggregated data for the selections at the Peer prompt:

  • Peer 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.
  • Peer Geometric Observed - The geometric mean length of stay (LOS) for the LOS Outcome Cases.
  • Peer Geometric Expected - The expected value for the Outcome Cases, calculated using the 3M™ risk-adjustment methodology and the arithmetic mean.
  • Peer Geometric Variation - The Observed value minus the Expected value.
  • Peer 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.
  • Peer 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.

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:

  • Facility CMS HAC Cases After Admit - The number of patients with at least one CMS Hospital Acquired Condition (HAC) after admission.
  • Facility Arithmetic Expected - The expected value for the Outcome Cases, calculated using the 3M™ risk-adjustment methodology and the geometric mean.
  • Facility 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.
  • Facility Arithmetic Observed - The arithmetic mean length of stay LOS for the LOS Outcome Cases.
  • Facility 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.
  • Facility Arithmetic Variation - The Observed value minus the Expected value.
  • Facility 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.
  • Facility 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.
  • Facility Total Cases - All cases that qualified for the analysis.
  • Facility Total Days - The total number of days for the LOS Total Cases.
  • Facility Total Days for ALOS Outcome Cases - The total number of days for the LOS Outcome Cases.

The following metrics represent the aggregated data for the selections at the Peer prompt:

  • Peer CMS HAC Cases After Admit - The number of patients with at least one CMS Hospital Acquired Condition (HAC) after admission.
  • Peer Arithmetic Expected - The expected value for the Outcome Cases, calculated using the 3M™ risk-adjustment methodology and the geometric mean.
  • Peer 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.
  • Peer Arithmetic Observed - The arithmetic mean length of stay LOS for the LOS Outcome Cases.
  • Peer 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.
  • Peer Arithmetic Variation - The Observed value minus the Expected value.
  • Peer Total Cases - All cases that qualified for the analysis.
  • Peer Total Days - The total number of days for the LOS Total Cases.
  • Peer Total Days for ALOS Outcome Cases - The total number of days for the LOS Outcome Cases.
