This report, based on the National Ambulatory Medical Care Survey (NAMCS) Physician Workflow Survey 2011, examines physician experiences with Electronic Health Record (EHR) systems, comparing clinical and financial indicators between those with and without systems meeting meaningful use criteria. The findings indicate that approximately three-quarters of physicians with EHR systems have systems meeting federal Stage 1 Meaningful Use Criteria, and these physicians reported time-saving efficiencies like faster lab results and electronic prescribing compared to those with systems not meeting the criteria. Furthermore, physicians using EHR systems meeting meaningful use criteria were less likely to perceive disruptions in patient interactions and more likely to agree on enhanced data confidentiality. While most physicians perceived clinical and financial benefits regardless of whether their system met meaningful use criteria, common challenges included increased time spent documenting care and potential disruption of patient interactions. The study highlights the impact of the HITECH Act of 2009 on EHR adoption and use in physician practices.
