"Helps me organize my rule outs and diagnostic tests I may need. Helps me realize if I’m missing a rule out or important test or there is something I am not familiar with and need to bone up on! If you don't know it’s out there, you won’t ever diagnose it!"

"Great visual for education to owner on path of workup. Good guidelines to not rule out anything too quickly."

"I don’t use them often, [but] if I do it’s only for a case where I’m stumped and can’t decide what to add on to my original testing."

"A good way to develop a problem-oriented approach to making a diagnosis."

"Helpful when formulating a diagnostic plan and which tests to prioritize. Also helpful in developing complete DDX lists!"

"They give me a straightforward way to approach a case. If I were to read several articles on a topic, I would most likely make an algorithm tree in my notes as a way to summarize the relevant information succinctly. They make more things make more sense."

"Great for not overlooking the unusual. I have been in practice for many years and know it is easy to omit uncommon diseases from your diagnosis and therefore make errors."

"It is an efficient and easy early consultation [tool] when working a case in which we don't have the best or current treatment protocol."

"Great refreshers when working up a case. In a busy practice and during emergencies, they make my job more efficient. They bring every aspect of the problem to the forefront so nothing is missed. "

"Some of them are very useful, usually in the middle of a case for finding the next diagnostic step after initial diagnostics are done."
