Nurses were kind. Facility was clean. They tried. Took daughter, who has a history of type 2 diabetes in on the referral of her PCP for sudden, very high blood sugar levels. (Daughter has other complex health issues as well.) Waited in the lobby after triage for 2 hours, then allowed a gurney in the hall (the place was packed). Two more hours and a doctor appeared and asked why she was there. Was told her medical history and that the PCP had recommended the visit in very certain terms. Doctor went away. IV was set and blood drawn. Two hours later doctor reappeared and told us she had Type 2 diabetes, the same blood work that was drawn as at her PCP had the same results. (One of the tests is known for giving false positives for people with one of her other issues, and we discussed that with the doctor, but in examining the paperwork later that is the one of the tests he ordered to check for Type 2 diabetes.) She was ready to be discharged. No meds given just a prescription and a referral - which could have come from the PCP, really. The ER doctor was very nice, but Well, ~THAT~ was pointless and will cost us dearly in co-pays. And, to top it, I'm sure we'll have an insurance nightmare. The PCP had said she had phoned ahead to let them know we were coming by private car. Since PCP was at UCSD and they are supposed to share systems, we assumed all was ready - but while my daughter was laying on the gurney after check-in a guy from registration showed up saying they could not find her insurance in the system, and so she was being treated as a "self-paying" customer. So, one 7 hour stay in the ER, one hysterical daughter, nothing out of it we didn't know when we went in, and I'm sure the bills will arrive soon no matter what we do. I really want to know, now, what the PCP thought was so important that it required an ER trip, when at the ER they did nothing the PCP had not already done?
