2020 was stunning…in the most ironic sense of the word. A side effect of the pandemic is that all eyes are on the healthcare and healthcare IT sectors. VC funding increased. Healthcare organizations adopted technologies at an unprecedented pace. Further, digital health companies responded with massive creativity to tackle a monster we’ve never seen before. There’s a lot of opportunity brewing here. But as in all historically bureaucratic industries, there’s also a LOT of red tape. Part of that paradigm is all the fundamental healthcare terms and health tech acronyms that are central to engaging the digital health space.
All of this can be dizzying so we’ve compiled a glossary of the most important healthcare IT terminology.
