Re: Discharge oasis vs Admission oasis discrepancies
CMS (Center for Medicare and Medicaid Services) says you should not reference the prior assessment when completing a new assessment. In practice, everybody does it, and most agencies do review the DC OASIS for declines. HOWEVER... your Case Manager or anyone else absolutely cannot change your documentation without your permission. My agency uses an "OASIS change report" on which all changes are noted and the clinician's signature is obtained. Do not sign anything you are not in agreement with. This is your name and license on the bottom line.
Keep in mind that OASIS can be interpreted very differently by different clinicians. Often you have to leave logic and reason at the door to arrive at the appropriate answer per CMS definition. Be open to what your supervisor tells you and ask for clarification about "Moo" questions if you need it. I recommend looking at Chapter 8 in the OASIS Manual as well.
It is not unusual for a "decline" to occur on paper because the prior OASIS was scored incorrectly. In that case, the case manager needs to go back to the last OASIS clinician and discuss possible changes with them.
