EHR systems can affect patient safety, workflows, and user satisfaction depending on how they are designed. Good EHR systems will always present a complete medication list to physicians rather than automatically removing expired medications. Top EHR vendors do not allow automatic removal of medications from patient lists unless done by physicians themselves. Truly integrated and intuitive EHR systems built around patient safety provide physicians with necessary options, while web-based EHRs on a single platform can help reduce costs and improve safety. Not all EHR systems offer beneficial features, and some waste time and money.
