I'm a third year PBLer, and I did pretty well on the boards. I'm not sure how the three pathways compared (Archer, how do you know?) It may be subjective and based only on my class, but it seemed on the whole, LDPers griped alot more about their daily workload than the other two pathways. This could have been to a couple incidents throughout the year, but what it comes down to is personal choice.
Firstly, motivation isn't really a priority. If you're not motivated, you fail medical school. People who come into school with a bio degree and a vague desire to become a doctor usually fail sometime after anatomy. It really comes down to what type of student are you. In college, did you email professors or T.A.s for help? Did you go to their lectures, and when you didn't, were totally lost? LDP. Were you like me? Never attending lecture, reading chapters based on the syllabus, forming study groups, etc. PBL or ISP. I have a serious problem with somebody telling me how something works instead of me figuring it out for myself. So lecture was a waste of time. But some people need that type of guidance or structure. Personally, I had trouble in undergrad with cramming and proscratination, but I think the fear of failing made studying hard a priority. In that sense, PBL taught me to schedule my time better.
In terms of how we're doing on rotations, I'd say again it's individualized. Personally, I've never heard a doctor say PBL or LDP or ISP makes a better 3rd or 4th year (although, I have heard Dr.s say we're better students than the ones they get from Temple or Jefferson. In your face, Philadelphia!). During the 2nd year, I thought I got a better clinical education through the PBL CODA than the LDP one. But I think that's a moot point, since rumor has it the insatiable beast that once was Ortoski's CODA program met the business end of a shotgun, and is now replaced with something similar to the old PBL format.
Pro's of PBL? Your own schedule. I'd study 8-10 hours a day, and still be able to wake up at 10 if I wanted to. Also, learning on my own somehow made the material more concrete. And, at the end of second year, I distinctly remember having more time to study for the upcoming boards beings that PBL was done sometime in March. Groups really gave a more realistic approach to cases, and it definately integrated the material in terms of using all disciplines in one area of medicine. Example: for a case for gout, you could study joint pathology, biochemistry protein metabolism and purine degradation, genetics for Lesch-Neyan disease (personally, my favorite genetic problem), anatomy, and pharm for allopurinol and colchicine. It really gave you an idea for the scope of knowledge you need just understand one problem.
Con's? You really have to be able to tolerate different personalities in a group. There's slackers, gunners, people who try to finish your sentence for you, and people who hide in corners silently sobbing. You may repeat objectives 4-5 times. Here's how: let's say last test, in a previous group, you read all about heart path. In this new one, there's somebody who didn't. You do it twice. And so on. Also, while reading material, you constantly have to ask yourself: is this important? Deciding what's worth remembering and what's not is half the battle in PBL. Not a worry for LDP or ISP, where their objectives are printed out for them.
Was I happy with PBL? God yes. I think 8-10 hours a day in a room (esp with some of the professors) would have me sticking sharp objects in my ear on a daily basis. And I'm happy with where it put me in terms of rotations. Honestly, I'm suprised with LECOM. It seems they've made me a pretty respectable student, and a candidate for some tough residency spots. Who thought that was possible?
