I have worked all four facilities through agency.
Harborcare is very nice; I think the biggest reason is there is a lot of family involovement with the residents. Acuity is low and nurses have plenty of time to get their nursing tasks done; I remember on occasion even asking the aides if they needed help, LOL. And the aides are very good and know the patients really well.
Town Center is also a very decent facility. The DNS is a wonderful woman and the two RCMs I worked with are very capable and nice too. If you work the skilled side, your typical caseload would be 10-12 patients as opposed to up to 20-30 in some other facilities. It's a little different because although you have a med aide, you pass all the bowel, PRNs, coumadins and I think some other heart meds. Still, most shifts there are very manageable and the other nurses are easy to get along with and helpful.
I would stay far, far, FAR away from Laurelhurst and especially Porthaven. Laurelhurst is probably the "typical" nursing home scenario that you hear people gripe about; nothing stands out, really...just not enough staffing. When I worked there I had one floor to myself plus half of another floor that I shared with another nurse. The upshot is that the shared floor tended to get neglected by both nurses, who also had to share a key to the treatment cart. Very much a logisital nightmare and you had to run run run your behind off with a "typical" 15 minute lunch break if you were lucky.
Porthaven BY FAR is the worst facility I've been to as an agency nurse. The double whammy is I was also a pretty new agency nurse at the time. I showed up and got a very scant report for one group of patients from another agency nurse who said "I don't know much about these people." I got no report at all from the other nurse (this was evening shift; apparently they used two nurses for days, one for evening). The nurse working the other side for the evening shift handed me a stack of labs and said "I have the MD on the line, read these to him." One of the labs was a very critical platelet value and when I read it to the MD he freaked out and told me to send the pt. out 911 right away but then asked if there was a regular staff nurse who knew the patient; thankfully the RCM was in her office and willing to take the call (turns out the pt. had advanced HIV and was sent out 2-3 times a week to receive packed platelets and his appt was for the next day). I got NO report on this patient. On top of that the staff could never be found (I'm sure they were also running their buts off b/c of the acuity level). Never again!
I know I'm responding to this pretty late in the game...curious as to where you wound up. Let me know!
