In this medical malpractice action, plaintiffs appeal the grant of summary disposition on the basis of the existence of an agreement to arbitrate. MCR 2.116(C)(7). We affirm.
Plaintiff Patricia Grazia (hereafter plaintiff) had an elective laparotomy on February 12, 1988. On February 9, 1988, plaintiff visited the hospital for preoperative tests. At the same time, she executed a surgical consent form ("Crittenton Hospital Consent to Operation and Treatment”) and an "Arbitration Agreement.” The agreement complied with the requirements of MCL 600.5040 et seq.; MSA 27A.5040 et seq., the Malpractice Arbitration Act (maa).
Plaintiff developed complications after surgery, allegedly because of the negligence of the various defendants. She brought suit in January 1990. Defendants moved for summary disposition, citing the February 9, 1988, arbitration agreement. The trial court granted the motion, and plaintiff appeals.
Plaintiff argues that the February 9 arbitration agreement applies only to the preoperative testing and other procedures performed on that day and does not include the surgery and hospitalization that began on February 12. We disagree.
The applicable standard of review under MCR 2.116(C)(7) requires us to accept all of plaintiffs well-pleaded allegations as true and to construe them most favorably to the plaintiff.

Bezou v Pierce,
MCL 600.5042; MSA 27A.5042 provides:
(1) A person who receives health care in a hospital may execute an agreement to arbitrate a dispute, controversy, or issue arising out of health care or treatment rendered by the hospital. . . .
(6) Each admission to a hospital shall be treated as separate and distinct for the purposes of an agreement to arbitrate but a person receiving outpatient care may execute an agreement with the hospital which provides for continuation of the agreement for a specific or continuing program of health care or treatment under the provisions of [MCL 600.5041; MSA 27A.5041],
(8) An agreement to arbitrate which includes the provisions of this section shall be presumed valid.
The maa evidences Michigan’s strong public policy favoring arbitration.
Marciniak v Amid,
The burden of establishing the existence of an arbitration agreement that conforms to the strict requirements of the statute rests with the party seeking to enforce the agreement.
McKinstry v Valley Obstetrics-Gynecology Clinic, PC,
A trial court’s evaluation of the evidence before it and its decision to place the burden of rebutting the presumption of the validity of an arbitration agreement on the plaintiff will not be overturned absent clear error.
Campbell v St John Hosp,
Harte v Sinai Hosp of Detroit,
Plaintiffs . . . argue that alleged malpractice occurring before the agreements were signed is not *586 covered by the arbitration agreements. We disagree. . . . Since Karen Harte only went to the ■ hospital once, and testified that she understood that the agreements related back to the hospital stay, and since liberal construction is appropriate, the arbitration agreements apply to malpractice in connection with plaintiffs son’s birth. Similarly, plaintiffs’ claims which arise out of prenatal care should also be included in the arbitration proceeding. They are inextricable from the arbitrable claims because they involve the same damages. [Id. at 665; emphasis supplied.]
Contract principles apply to arbitration agreements.
McKain, supra
at 253. The question of when parties become contractually bound depends upon their intention as manifested by their verbal statements and conduct in light of all the circumstances.
Hawker v Northern Michigan Hosp, Inc,
Plaintiff relies on the fact that the arbitration agreement makes reference to "this hospital stay,” as did the agreements in
McKain, supra,
and
Haywood v Fowler,
It is manifest from the parties’ "conduct in light of all the circumstances,” Hawker, supra, that the consent form and arbitration agreement signed on February 9 related to the upcoming laparotomy. In an unrebutted affidavit, the manager of the hospital’s preadmission testing and endoscopy unit testified that, during the. preadmission procedure, "[t]he patient is clearly told that the Arbitration Agreement is for their [sic] upcoming admission.” Such habit or routine evidence is admissible in cases involving hospital arbitration agreements; see, e.g., McKinstry, supra at 181; Green, supra at 538. Plaintiff, by contrast, did not plead and has submitted no evidence that she believed that the arbitration agreement related only to the February 9 procedures. Defendants have presented prima facie evidence of a valid arbitration agreement, and plaintiff has failed to rebut it. The statutory presumption of validity applies; McKinstry, supra at 181.
Affirmed.
