Readmission rate: No relationship with length of stay

In a study of over 4100 adult patients who received care 2004 to 2006 at one academic medical center, researchers found that there was no statistically significant relationship between a longer or shorter length of stay in the hospital and the likelihood that the patient would be readmitted either at 30 days or at 120 days. 

  • The interesting conclusion: “In summary, hospital care, as measured by the incremental probability of readmission for every incremental day in LOS [length of stay], has no association with readmission.  If our findings are confirmed at other hospitals, then more hospital care may not be the mechanism for reducing readmission rates.  If that is the case, then denying payment for readmission may be likely unwarranted.” (p. 73)
