LOS Comparison - Facility 3M™

This analysis enables you to evaluate the LOS outcomes for a defined population. Use this analysis to identify opportunities 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 - SPL
  • Facility Payers
  • Standard Primary Payers
  • Standard Secondary Payers
  • Patient Qualifications

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

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.
  • Arithmetic Observed: The arithmetic mean length of stay LOS for the LOS Outcome Cases.
  • Arithmetic Expected: The expected value for the Outcome Cases, calculated using the 3M™ risk-adjustment methodology and the arithmetic mean.
  • 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.

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