This study examined the relationship between advanced electronic health record (EHR) use in hospitals and rates of Methicillin-resistant Staphylococcus aureus (MRSA) infection in an inpatient setting. National Inpatient Sample (NIS) and Health Information Management Systems Society (HIMSS) Annual Survey are combined in the retrospective, cross-sectional analysis. A twenty percent simple random sample of the combined 2009 NIS and HIMSS datasets included a total of 1,032,905 patient cases of MRSA in 550 hospitals. Results of the propensity-adjusted logistic regression model revealed a statistically significant association between advanced EHR and MRSA, with patient cases from an advanced EHR being less likely to report a MRSA diagnosis code
