Appropriateness of admissions and discharges among readmitted patients.

This study examined the relationships between appropriateness of readmission within two weeks of discharge and appropriateness of previous admission and discharge, bed section, type of readmission, and patient demographic, medical condition, and hospital stay characteristics. Using the Department of Veterans Affairs (VA) Patient Treatment File and medical records, 445 readmissions to a highly affiliated midwestern VA Medical Center in fiscal year 1984 were examined. Appropriateness was determined by four trained medical record abstractors using InterQual admission and discharge standards. Type of readmission was based on a pilot-tested flowchart. Appropriateness of readmission was significantly associated with that of the previous admission and discharge, with the relationship varying by admission, discharge, and readmission bed sections. Reasons for inappropriate admissions, discharges, and readmissions also varied by bed section. For the majority of inappropriate readmissions, there was clear written evidence in the medical record during the previous hospital stay that the patient was directed to return for readmission. Inappropriate readmissions were more likely than appropriate readmissions to have a primary diagnosis of neoplasm or digestive disorder. These results indicate the importance of examining both the operational efficiencies during the previous admission and the clinical criteria for admitting, discharging, and readmitting patients in assessing the appropriateness of readmissions.
