recommend references for the following paragraph When studying the consequences of electronic health records (EHR) on workflow productivity and job satisfaction among healthcare providers in urban hospitals, the Technology Acceptance Model (TAM) and Socio-Technical Systems (STS) theory present a strong theoretical framework.

In this case, the model can be used to explain how healthcare providers' attitudes towards usefulness and user-friendliness of EHRs impact their readiness to incorporate it into their daily work routines ( ). These constructs should be measured through surveying medical staffs' opinions concerning these aspects so as obtain information about whether such views are related with actual alterations in workflow productivity or job satisfaction ( )
