The technical motivation for using failure to rescue to evaluate the quality of care stems from the concern that some institutions might document adverse occurrences more assiduously than other institutions. Therefore, using lower rates of in-hospital complications by themselves may simply reward hospitals with poor documentation. However, if the medical record indicates that a complication has occurred, the response to that complication should provide an indicator of the quality of care that is less susceptible to charting bias.
