Trauma patients were subjected to the 30-day follow-up with the ACS NSQIP tools to assess readmission rates. The existing standard hospital and trauma registry data review was used to determine readmission, with the same group assessed for readmission using the information collected with the modified TQIP tools. All data collected via this method were patient reported and verified by review of records at our facility and via patient-authorized outside record review.
Six hundred and ninety-eight consecutive patients were admitted to the trauma service during the study period and 378 (54.1%) were contacted by telephone for interview. Demographic characteristics were similar (p = NS). The readmission rate changed from 4.01% to 2.4% using the hospital and trauma registry subset (p = NS). Readmission rate by the modified TQIP method was 7.1% (p < 0.03). Readmitted patients did not differ with respect to routine follow-up visits.
We hypothesized that our observed and actual readmission rates differed. We discovered a significant difference in reported rates. Incorporating an NSQIP-like postdischarge feedback process can improve the accuracy of hospitals' readmission data and complication reporting, and thereby improve the value of the information TQIP uses as benchmarks.
