I hope that other members can help also, but this has been my limited experience with the medical care here....
First let me say, that my husband is active duty military, so we have great insurance and a doc on base that we see for routine care. However, we do not have access to speciality care military doctors here, being that it is an island, like we would in the States. I have heard horror stories about having to wait all day to see a doctor here, and still sometimes not being seen. So, I usually only go to the doctor once a year for my check-up, and I go back to the States when I am on holiday visiting family. I have been with my husband to the doctor when he needed a MRI and we did have a long wait, and the equipment seemed really old. They didn't have up-to-date technology and the ability to send the MRI work to the doc, they gave us huge images to take back. But, it did get the job done! Anything I have heard about the medical has been that is is not what it is in the States, which is why most military dependents do chose to go back to the States to give birth and for other speciality care appt. One other thing to consider is that we do live in the NW section of the island, so I am hoping that San Juan has better options, but again I have not heard good things. My husband job often requires him to drop patients off at the hospital that are in critical care and I have heard that the hospitals are not run up to U.S. standards.
All of this being said, I do realize that my experience with the system here as been limited. So, I do hope others will chime in. I am sure that there are good doctors here and I also would hope that there are better option closer to the metro area of San Juan, as we are a bit isolated over here. So, please other members, let us know your experiences.
