Based on scope and longevity....probably the diagnostic service digital platforms. Laboratory and imaging systems (PACS) have given all clinicians (with appropriate rights) access to far more diagnostic information including the primary data, not just reports. They have been around for decades and unlike primary care systems which are even older are a fairly generic and consistent service across settings.
All digital systems introduce (often new) risks but hopefully are at worst risk neutral...impossible to truly quantity but there are incontrovertible benefits to digitisation in terms of access, efficiency and secondary uses even if they are far from perfect even for those functions!
As or the last 2 questions.....there may well be strategies that answer your question but the fundamental deficit is in the foundations of digital systems which are not truly fit for purposes and require workaround upon workaround to deliver the reasonable functions of today and proposed functions of tomorrow. The future is always the day after and isn't on the agenda if that isn't too cryptic!
