And thousands of health care providers are burdened with costly, poorly designed, and insecure EHR systems that have exacerbated clinician burnout, led to hundreds of millions of medical records lost in data breaches, and created new sources of medical errors. Sadly, the lack of attention to these concerns affects current EHR systems.
Rules pertain to limitations on engine displacement and overall size, with the small models likewise not having to adhere to the same safety standards as their larger counterparts. If you actually look at our engineers, more than 25 [percent] just work on compliance. If you actually look at the (cars') cost increase. So no value added."
