  1. Potentially Preventable ReadmissionsRARE Mental Health Collab. Mark Sonneborn

  2. What are PPRs? • 3M software • Based on MHA administrative data • Measures readmissions to the same facility only • ~ 22% go to different facilities, per literature • How to interpret the reports

  3. General Guidelines for PPRs

  4. PPR Global Exclusions • If any of the following conditions apply to the initial admission, a subsequent readmission is globally excluded from consideration as a PPR • Admissions for which follow-up care is intrinsically extensive and complex • Major or metastatic malignancies treated medically • Multiple trauma, burns • Discharge status indicates limited hospital & provider control • Left against medical advice • Transferred to another acute care hospital • Neonates • Other exclusions • Specific eye procedures and infections • Cystic fibrosis with pulmonary diagnoses • Died – not included as candidate initial admissions (denominator)

  5. Clinical Factors make a readmission not potentially preventable • No clinical relationship to prior discharge • Cholecystectomy two weeks after hip replacement • Discharge status of prior discharge • AMA and transferred to another acute care hospital • Type of prior discharge • Follow-up care is intrinsically complex and extensive • Metatastic malignancies, Multiple trauma, Burns • Longer interval between discharge and readmission • Long time intervals (>30 days) reduce confidence that readmission is causally linked to the prior discharge

  6. Non- PPR Reasons

  7. How to interpret PPR results – Hospital-level PPRs is the actual number of PPRs detected during the time period

  8. How to interpret PPR results – Hospital-level “At Risk Cases” is the denominator – it’s all cases minus the exclusions mentioned before

  9. How to interpret PPR results – Hospital-level Actual Rate is PPRs divided by At Risk Cases

  10. How to interpret PPR results – Hospital-level Expected Rate – this is a unique number for every hospital based on their patient population. Generally, hospitals with more severely ill patients will have higher expected rates.

  11. How to interpret PPR results – Hospital-level One star is statistically “worse than expected” (or higher); Two stars is “no different than expected”; Three stars is “better than expected” (or lower)

  12. How to interpret PPR results – Hospital-level Expected PPRs is the Expected Rate times the At Risk Cases

  13. How to interpret PPR results – Hospital-level Target PPRs is 20% less than Expected PPRs

  14. How to interpret PPR results – Hospital-level Difference from Target is your actual PPRs (first column) minus the Target PPRs. The goal for this hospital is to reduce by 18 PPRs per year.

  15. Actual to Expected Ratio An A/E Ratio above 1.0 is more than expected; below is less than expected. The goal for the RARE campaign is to get the A/E ratio down to 0.80

  16. Example Detail (Record-level) Report

  17. Detail Reports • Acct #, Med Rec # • Admit, Discharge Date • APR-DRG, APR-DRG Severity of Illness • This is what the statewide norms are based on • PPR days • Days between discharge and admission • Record Type • 2-letter codes – THIS IS THE KEY FIELD • Principal Diagnosis, MDC, DRG • Discharge Status • Statewide Norm

  18. Hints for Using Detail Reports to Analyze Performance • Find patients that had potentially preventable readmissions • IA (Initial Admissions) have at least one affiliated RA (Readmission) • All of the other two-letter codes are not for patients that were readmitted • Use A/E ratio results from hospital-level report to hone in on certain types of cases • Look for patterns and characteristics of readmitted patients vs. non-readmitted • Are there differences in demographics or diagnoses?
