I've been around the block and back again in hospice. Regarding a census of 20, that requires two case managers (or one RN and one LPN) and about two aides. Assuming there is adequate staffing, you should not be picking up any missed visits for the case manager. I was doing dumped on with routine visits during my first on-call job because we had a green CM, and once she was replaced with a seasoned CM with a professional work ethic, I NEVER did routine visits on the weekends. I then became a CM and would do 4-5 visits daily, so with a mere 20 patients, I'd be asking what that CM is doing with all that extra time. Also, if the CM is doing the job properly by providing thorough education to the caregivers with inclusion of potential symptoms, in writing, then your job should be easy.
