Maybe they do and maybe they don’t. However, few patients actually access their electronic health record (EHR) when given the chance. According to a paper by Lin et al. (2019):
On average, hospitals gave 95 percent of discharged patients access to view, download, and transmit their information, but only about 10 percent of those with access used it—levels that were stagnant during the study period.
One key challenge is that EHR are written for a physician audience. Simplified language and instructions are needed to engage patients, and this translation to a new audience is a non-trivial task. Further, patients are busy and may feel stressed and accessing complicated documents may be stress inducing. Further, access is likely especially low for non-English speakers.
Thus, despite the promise of EHR, currently these records have value only for a small minority of patients.
