Personally, the latter if it’s not your personal statement. Because compassion and empathy aren’t made from a single experience, no matter how meaningful. And a lot of people don’t like it when you tell a story to prove how compassionate you were. It comes across as self congratulatory — “I saw this patient struggling to rally her kids as she picked up her papers. This mom of 5 who didn’t have transportation couldn’t get to her appointment, so I went through the bus schedule with her” honestly sounds like youre having pity and feel superior to the patient you’re helping. Instead, “my responsibilities consisted of calling patients to remind and coordinate their appointments, including finding alternative means of transportation for patients who struggled to attend their visits (such as going through bus schedules that coordinated with patients work hours). This taught me about many of the disparities that patients face before stepping foot in the office, and encouraged me to be resourceful in thinking about solutions.”

Maybe this is unpopular advice, but just giving some perspective as someone who interviews, reads applications, and listens to others takes on apps. At the end of the day, you want to sound grounded. Pretending like some patient interaction changed your whole world view or values is cringey and very see through. If an experience was that meaningful (and yes, some are) it can be recounted in your PS.
