Background This study aims to assess patient coverage, validity and data quality in the Swedish part of the International Enhanced Recovery After Surgery (ERAS) Interactive Audit System (EIAS). Method All Swedish ERAS centers that recorded colorectal surgery data in EIAS between January 1, 2017, and December 31, 2017, were included ( N = 12). Information registered in EIAS was compared with data from electronic medical records at each hospital to assess the overall coverage of EIAS. Twenty random‐selected patients from each of the contributing centers were assessed for accuracy for a set of clinically relevant variables. All patients admitted to the contributing centers were included for the assessment of rate of missing on a selection of key clinical variables. Results Eight hospitals provided complete information for the evaluation, while four hospitals only allowed assessment of coverage and missing data. The eight hospitals had an overall coverage of 98.8% in EIAS ( n = 1301) and the four 86.7% ( n = 811). The average agreement for the assessed postoperative outcome variables was 96.5%. The accuracy was excellent for ‘length of hospital stay,’ ‘reoperation,’ and ‘any complications,’ but lower for other types of complications. Only a few variables had more than 5% missing data, and missingness was associated with hospital type and size. Conclusion This validation of the Swedish part of the international ERAS database suggests high patient coverage in EIAS and high agreement and limited missingness in clinically relevant variables. This validation approach or a modified version can be used for continued validation of the International ERAS database.
