Hospital readmissions within 30 days of discharge may not be a good way of judging the quality of care hospitals provide, a new study suggests.
Seven days may be more like it.
According to a new study published in the journal Health Affairs, the impact of the quality of care a hospital provides appears to be most evident immediately upon patients’ discharge from the hospital.
Further, the study suggests,

… most readmissions after the seventh day postdischarge were explained by community- and household-level factors beyond hospitals’ control.

The researchers’ conclusion?

Shorter intervals of seven or fewer days might improve the accuracy and equity of readmissions as a measure of hospital quality for public accountability.

The findings call into question the approach employed by Medicare through its’ hospital readmissions reduction program. Some of the issues the study cites – community and household factors – are the very kinds of challenges that Pennsylvania’s safety-net hospitals face far more often than the typical community hospital in the state.
