There are no government hospitals or private medical facilities on Bastimentos. The nearest (small) hospital with no specialists to speak of is in Bocas town. There is a slightly better hospital in the mainland town of Changuinola, 1 hour away including water taxi to the mainland, and there are perfectly good private hospitals in the mainland town of David, a 4 hours trip away (counting getting to the mainland). You are also 1 hour away by plane, from world class medial services in Panama City.
