Same reason every other awful UI is awful: egos, opinions, hubris, turf, ignorance, neglect, incompetence, resource constraints, NIH, etc, etc. I designed and implemented the back half of a caregiver facing "portal", working hand in glove with our people making the front half. And I prototyped what became our patient facing portal (think MyChart). And I wrote a medical image viewer. We were first to market, had customers that loved us, making money. Then our product team was sold to MedPlus (Quest Diagnostics). Who promptly destroyed all of our work. I'd already been thru a handful of acquisitions beforehand (both sides), so I knew what to expect. The Golden Rule. He who has the gold makes the rules. Even so, as a patient, stuff like Epic, Cerner, MyChart, etc. fills me something like despair, rage, hopelessness. Just today, reviewing my scripts, during a visit, yet again... The hospital's list of scripts for me is wrong. Again. Despite being manually corrected every time I visit. I know PRECISELY how and why it's wrong. Because I fixed those exact queries myself, back when the hospital had been one of our customers. Over a decade ago. So aggravating. As you can guess, a new CTO had come in with grand ideas and ambition to match, threw away their predecessor's work (including our product), and brought in Epic. Same as it ever was, I suppose.
