I found a membership in the Hospice and Palliative Nurses Association (HPNA) helpful , they also have a journal. The core curriculum is a great book and has helped me significantly.
Get familiar with the Medicare Hospice benefit and get a cheat sheet.
Get the FAST scale and other assessment tools you will need.
Those are really important items for me : car charger (especially in home hospice because you will be driving a lot as opposed to a hospice house), GPS or phone with GPS app, space in your trunk if you are doing home hospice for all the supplies you will need ....
Get organized and get one binder with protective sleeves for forms (pronouncement forms, standing orders, revocation, notice of non coverage, phone numbers for other nurses/team/MD, ....whatever forms are used in your work place .
Get one binder with information you won't need all the time but good to have especially when you are home hospice (CADD pump instructions, Hospice criteria , and so on).
I have apps on my phone that I think are useful like medication apps, narcotic apps and so on .
Black pen (for the pronouncement), sticky notes, small note book.
When I started I asked my preceptor what she had in her car and she gave me an idea what I would need on a day to day basis and helped me to get those things in the agency. In home hospice you need to be prepared to insert foleys, you may have to access ports, change central line dressings, drain pleurx , need extra syringes without needles for oral medication administration, at least one box of unsterile gloves, needle box, diapers and chucks, urinals and bedpans .... just ask the other nurses what they have in their trunks.
When you start program the phone numbers you will need most right into your phone and get a hands free device if you are driving as a home care hospice nurse - you want the hospice doctor, hospice manager, perhaps the educator and other nurses on your phone as well as the pharmacy, elder services, hospice social worker, hospice spiritual /chaplain, volunteer coordinator and so on.
Good luck !!
