This systematic review evaluated the impact of providing patients with access to electronic health records (EHR) on measures of quality of care (i.e., patient-centeredness, effectiveness, efficiency, timeliness, equity, and safety). Meta-analysis found that sharing EHRs with patients is effective in reducing HbA1c levels; the included studies generally found positive effects on patient-centeredness, health outcomes, and adherence to preventative services. However, the authors concluded that more methodologically robust studies are necessary to quantitatively assess the impact of sharing EHRs with patients.
