Before you undergo outside training and seminars, learn with the current MDS coordinator first. Have your bosses allow you to spend full time working w/ the coordinator during the remainder of her stay.
Take the RAI Manual home and start reading Chapters 2, 3, 4, and Appendix C. Free online training --
Long-Term Care Resident Assessment Instrument/Minimum Data Set (RAI/MDS) Training
Any seminar or training can be better understood w/ a basic knowledge of the MDS process. Besides OBRA requirements, MDS is used for reimbursement purposes. Inaccurate MDS coding and unwise use of assessment timeframes can spell huge monetary losses.
A more detailed online training is available for a fee. Check w/ your state RAI Coordinator for any upcoming training or seminar available in your area.
You can also subscribe to a discussion group which is very beneficial to MDS coordinators regardless of expertise.
An MDS coordinator is still an undervalued position in most facilities. Owners and administrators do not have a full grasp yet on what a nurse's knowledge in this position can bring about. Good luck!
