Yes, for hands-on care. COMAR 10.07.05.12E(1) says: "For clients who require skilled services or assistance with the activities of daily living, an agency shall have a registered nurse to provide oversight for" implementation of the care plan, delegation, supervision and training (COMAR 10.07.05.12E(1)). Activities of daily living include bathing, dressing, toileting, eating and transfers (.02B(1)).
What the RN does. Assesses each new client who needs skilled services and help with daily living, takes part in the plan of care and staff assignment, decides whether a certified nursing assistant is needed, and helps train caregivers (.12B). The RN supervises care on site at least every 4 months, every 3 months when staff help with self-administered medication, and every 45 days when staff administer it (.12E(2)).
Delegation follows the Board of Nursing. The nursing assessment and the nursing care plan may not be delegated, and "The delegating nurse retains the accountability for the nursing task" (COMAR 10.27.11.05A; .03A). The RSA rules do not say whether the RN must be an employee; Medicaid’s Community First Choice providers must employ one (COMAR 10.09.84.06A(2)).
