Section 3A. The administrator or person in charge of a hospital shall be required to obtain, within twenty-four hours after a birth occurring therein or the admittance thereto of a mother and child for post-natal care, the report required by section three. If the hospital in which such birth occurred delivers more than 99 births per year, such report shall be prepared on an electronic system of birth registration approved by the commissioner of public health and transmitted to the state registrar. Said administrator or person in charge shall then forthwith make, or cause to be made, a copy of such report on forms prepared and furnished by the commissioner of public health and shall, within ten days after obtaining such report, file such copies with the town clerk of the city or town wherein the birth occurred. Such copies shall be signed or otherwise verified by the mother in a manner developed pursuant to regulations promulgated pursuant to section 4 of chapter 17, or, if she is not able, then by the father or other responsible adult, attesting to the truth and accuracy of the facts appearing in the report. Such copies shall also be signed or otherwise verified, in a manner specified under regulations promulgated pursuant to section 4 of chapter 17, by the physician, certified nurse midwife or hospital medical officer in charge of such birth or by an administrator designated by the hospital as overseeing birth registration.
