14- 191 C.M.R. ch. 3, § V
Staff shall monitor the patient's condition on at least a daily basis and report any change to the attending physician. The attending physician shall conduct a thorough and formal review of the condition and capacity of the patient at least every 90 days to determine if a DNR order is still appropriate in light of the patient's condition. Such review shall include consultation with other treating staff. Progress notes shall reflect this periodic review. If a significant change in condition does occur, the physician shall notify the patient, if possible, or the patient's surrogate of such change. Each institution shall attempt to obtain a reaffirmance of the initial consent to a DNR order after each reevaluation but, in any event, at least every 90 days. Each institution shall be responsible for obtaining new authorization should the appropriate surrogate change.
