UM, OP, I have to disagree with the "no one is acutely ill in home health", When I did home health (VNA) many of my patients were very seriously ill and several were fairly unstable.
Usually a soc involves the process of admitting the patient, observing his status as to how independent he is, assessing any services he might need, pt, hha, msw, etc Usually that is at the very minimum usually 45 minutes with the patient, and then charting his meds, medical hx,care plan et al, after that-admissions even uncomplicated ones usually take much longer to complete I've done uncomplicated ones with the patient on few meds that took about an hour and a half to very complicated ones with the patient on many meds, comorbidities etc that took over 4 hours. The computer program they use can be a help or hindrance in getting it done faster.
ROC basically takes a few minutes just requires patients to sign forms and "if you have any problems call your doctor"
as far as them not teaching you oasis, that is kind of silly on their part, oasis really isn't complicated but the phrasing of certain things is... and not giving you proper training means you may inadvertently cost them money by having a soc, or re-certification denied or audited by CMS-very not good.
When I worked home health (VNA) I was told that ber CMS, and insurance guidelines we had to physically be in the home at the very minimum 30 minutes. Now if you're seeing a total joint and just doing a wound check, honestly that can get challenging but in most cases I would work around it by telling the patient I was required to chart in the home, and starting charting there as well as using the edmonton scale, so most times I was able to make a 1/2 hour, then I would finish charting in the car in their driveway (try not to do charting at home) for the patients who wanted me in/out I would try to leave within 30 minutes. I almost always finished charting in the house or the driveway. then there are the patients who see your visit as a social occasion, and offer you food and drink.
Sorry, I digressed, but in my experience working for multiple agencies, this is not really typical of orientation, usually you will either look over the persons shoulder while charting or do a "dummy" chart that they can review. and the fact they don't seem at all concerned about oasis training is weird in that how those questions are answered can result in them not being paid. Unless they are a complete private pay company (there are some) I can't see why they wouldn't want to give you at least information, I've had oasis training at different companies that varied from 8hrs to 3 very long, very boring days. Best of luck.
