BRICKLEY, J.
We granted leave in these cases to determine if the physician-patient privilege set forth in MCL 600.2157; MSA 27A.2157 prevents the defendant hospitals from disclosing the identity of unknown third-party patients. We hold that the names of unknown patients are protected by the physician-patient privilege, and that defendant hospitals have a duty to refrain from disclosure. We also review the Gregory trial court’s order that the defendant hospital provide Gregory with any investigative reports rela[29]*29tive to the incident report; any statements made by any person with respect to the incident; and any notes, memoranda, records, and reports related to the incident. Additionally, we review the Gregory trial court’s denial of the defendant hospital’s motions for summary disposition for plaintiff’s failure to file a notice of intent and for plaintiffs failure to, file an affidavit of merit. We decline to review the Gregory trial court’s partial denial of defendant’s motion for partial summary disposition regarding plaintiff’s express contract claim for violation of the statute of frauds and the Michigan Court Rules. We affirm the judgment of the Court of Appeals with respect to Dorris v Detroit Osteopathic Hospital. We partially reverse the trial court in Gregory v Heritage Hospital and remand the case for further proceedings consistent with this opinion.
i
A. DORRIS v DETROIT OSTEOPATHIC HOSPITAL
This is an interlocutory appeal in a medical malpractice action. Plaintiffs Deborah Dorris and Raymond Dorris1 appeal the Court of Appeals reversal of the trial court’s order compelling defendant Detroit Osteopathic Hospital Corporation to reveal the name of the patient who shared a hospital room with Dorris.
Plaintiff Dorris visited the Riverside Osteopathic Hospital2 emergency room on the evening of June 18, [30]*301993, complaining of nausea, vomiting, and diarrhea. The emergency room physician, Dr. Lusk, prescribed the drug Compazine, which was administered intravenously. After the Compazine was administered, Dorris had an apparent anaphylactic reaction to the drug. Dorris’ condition later stabilized, and she was discharged within twenty-four hours. Dorris claimed that she had refused the Compazine because she had a history of allergic reactions to medicines. Dorris alleged that she instead requested Lomatil, which she previously had taken without incident, but Dr. Lusk refused her request. Dorris stated that she also told the nurse who put Compazine into the intravenous bag that she did not want the medicine.
Dorris filed suit in March 1994 and alleged that the hospital’s employee negligently administered Compazine in violation of the standard of care for an emergency room physician and against Dorris’ specific instructions. Dorris’ complaint alleges damages for the allergic reaction, as well as pain, suffering, humiliation, and great emotional and mental distress. Dorris’ husband alleges damages as a result of loss of consortium.
Dorris claims that the patient who shared her hospital room witnessed Dorris’ refusals of Compazine. During discovery, plaintiff moved to compel defendant to disclose the name of that patient. The circuit court granted the motion. The Court of Appeals reversed. 220 Mich App 248; 559 NW2d 76 (1996). The Court of Appeals based its holding on Schechet v Kesten, 372 Mich 346, 351; 126 NW2d 718 (1964). In Schechet, this Court stated that MCL 600.2157; MSA 27A.2157 “prohibits the physician from disclosing, in the course of any action wherein his patient or [31]*31patients are not involved and do not consent, even the names of such noninvolved patients.”
Plaintiff Dorris appeals the decision of the Court of Appeals. 457 Mich 866 (1998).
B. GREGORY v HERITAGE HOSPITAL
In her complaint, plaintiff Eloise Gregory alleges that she was the victim of an assault and battery occurring while she was a patient at defendant Heritage Hospital on May 13, 1997. She claims that she was awakened because of a physical altercation between her roommate and another patient from across the hall. Gregory alleges that she was grabbed by defendant Jane Doe who pushed her to the ground and beat her, causing her to lose consciousness and sustain serious injuries. Additionally, Gregory alleges breach of contract by Heritage. Gregory argues that this contract gave rise to a duty of Heritage to protect patients while under its care. Gregory also alleges that Heritage had inadequate staffing to supervise and monitor the behavior of the patients under its psychiatric care.
Gregory served Heritage with interrogatories and a request for production of documents that included: any incident/investigative reports relating to the incident; any statements made by any person with respect to the incident; and any notes, memoranda, records, and reports related to the incident.
Heritage objected to the discovery requests. In lieu of answering the complaint, Heritage filed three motions for summary disposition. Gregory subsequently filed a motion to compel discovery. Heritage’s motions for summary disposition were in large part [32]*32denied, and Gregory’s motion to compel discovery was granted.3 Heritage was ordered to provide Gregory with answers to her interrogatories; the incident report involving Jane Doe; Jane Doe’s full name, last known address, telephone number, social security number, or date of birth; any investigative reports relative to the incident report; any statements made by any person with respect to the incident; and any notes, memoranda, records, and reports related to the incident.
Heritage applied for leave to appeal in the Court of Appeals, which was denied. This Court granted Heritage’s application for leave to appeal and combined this case with Dorris v Detroit Osteopathic Hosp. 458 Mich 876 (1998).
n
We first address whether the defendant hospitals are required to provide identification information about other unknown patients to the plaintiffs. The physician-patient statute in Michigan, found at MCL 600.2157; MSA 27A.2157, provides:
Except as otherwise provided by law, a person duly authorized to practice medicine or surgery shall not disclose any information that the person has acquired in attending a patient in a professional character, if the information was necessary to enable the person to prescribe for the patient as a physician, or to do any act for the patient [33]*33as a surgeon. If the patient brings an action against any defendant to recover for any personal injuries, or for any malpractice, and the patient produces a physician as a witness in the patient’s own behalf who has treated the patient for the injury or for any disease or condition for which malpractice is alleged, the patient shall be considered to have waived the privilege provided in this section as to another physician who has treated the patient for the injuries, disease, or condition. If a patient has died, the heirs at law of the patient, whether proponents or contestants of the patient’s will, shall be considered to be personal representatives of the deceased patient for the purpose of waiving the privilege under this section in a contest upon the question of admitting the patient’s will to probate. If a patient has died, the beneficiary of a life insurance policy insuring the life of the patient, or the patient’s heirs at law, may waive the privilege under this section for the purpose of providing the necessary documentation to a life insurer in examining a claim for benefits.
The physician-patient privilege was not recognized at common law, and, thus, its scope is controlled by the language of the statute. People v Johnson, 111 Mich App 383; 314 NW2d 631 (1981).
It is well established that the purpose of the statute is to protect the confidential nature of the physician-patient relationship and to encourage a patient to make a full disclosure of symptoms and condition. Domako v Rowe, 438 Mich 347, 354; 475 NW2d 30 (1991); Gaertner v Michigan, 385 Mich 49, 53; 187 NW2d 429 (1971); Schechet, supra at 351; 81 Am Jur 2d, Witnesses, § 438, p 392.
This Court, in Gaertner, supra at 53, summarized the purpose of the statute as follows:
The purpose of this statute is to protect the confidential nature of the physician-patient relationship. In Schechet v [34]*34Kesten, 372 Mich 346, 351 [126 NW2d 718 (1964)], this Court said of the statute:
“It prohibits the physician from disclosing, in the course of any action wherein his patient or patients are not involved and do not consent, even the names of such noninvolved patients.”
The privilege of confidentiality belongs to the patient; it can be waived only by the patient. Schechet v Kesten, supra. In Storrs v Scougale, 48 Mich 387, 395 [12 NW 502 (1882)], this Court by Justice Cooley said of this privilege of confidentiality:
“[A] privilege is guarded which does not belong to him [the physician] but to his patient, and which continues indefinitely, and can be waived by no one but the patient himself.”
In Schechet, this Court considered whether the physician-patient privilege prohibited the discovery of the names and treatment histories of patients in a libel and slander claim brought by plaintiff Dr. Schechet against defendant Dr. Kesten on the basis of an allegedly slanderous and libelous report Dr. Kesten made to a credentials committee about Dr. Schechet. Dr. Schechet sought the names and treatment histories regarding those patients whom Dr. Kesten accused Dr. Schechet of failing to appropriately treat in his report to the committee. This Court reversed the trial court’s order of disclosure, stating:
Such veil of privilege is the patient’s right. It prohibits the physician from disclosing, in the course of any action wherein his patient or patients are not involved and do not consent, even the names of such noninvolved patients. [372 Mich 351.]
In its decision in Dorris v Detroit Osteopathic Hosp, the Court of Appeals panel relied upon Schechet in finding that the names of nonparty [35]*35patients were protected by the physician-patient privilege and not subject to disclosure. Plaintiff Dorris argues that the panel committed error requiring reversal by wrongfully relying on this dicta from Schechet. Rather, Dorris argues that this Court should follow Porter v Michigan Osteopathic Hosp Ass’n, Inc, 170 Mich App 619; 428 NW2d 719 (1988). In Porter, the plaintiff sought disclosure of the names and information regarding two other patients who allegedly raped her while she was a patient at the Michigan Osteopathic Hospital. In upholding the trial court’s order of disclosure, the Court of Appeals found that disclosure of the names and addresses of unknown patients who were suspected as assailants did not require disclosure of information necessary for treatment or diagnosis pursuant to MCL 600.2157; MSA 27A.2157.4 Thus, the Court of Appeals found that the names and addresses of the unknown patients were discoverable.
The Dorris panel noted the Porter dissent that found that the physician-patient privilege “statute has not been construed as limited to information solely necessary for treatment.” Porter, 170 Mich App 627 (Mackenzie, J., dissenting). However, the Dorris panel noted that in Porter there were stronger policy reasons for disclosure, because the plaintiff was seeking the name of the patients who allegedly attacked her, [36]*36whereas, in Dorris, the plaintiff was only seeking the name of the patient who may have overheard a conversation between the plaintiff and medical personnel.
Gregory argues that her case presents stronger reasons for disclosure than those argued in Dorris and Porter. She argues that in the present case, the information requested is required to identify a party to the litigation. She would have this Court hold that, unless the information is necessary for the purpose of examination, diagnosis, or treatment, it is discoverable. She further argues that the identity of the unknown patient is not protected by the physician-patient privilege.
This state has a strong historical commitment to a far-reaching, open, and effective discovery practice. Daniels v Allen Industries, Inc, 391 Mich 398, 403; 216 NW2d 762 (1974). “[T]he Michigan Court Rules of 1985 in no way acted to restrict discovery or to modify this commitment to open discovery.” Domako, 438 Mich 359. MCR 2.302(B)(1), which governs the scope of permissible discovery, provides:
In General. Parties may obtain discovery regarding any matter, not privileged, which is relevant to the subject matter involved in the pending action, whether it relates to the claim or defense of the party seeking discovery or to the claim or defense of another party, including the existence, description, nature, custody, condition, and location of books, documents, or other tangible things and the identity and location of persons having knowledge of a discoverable matter. It is not ground for objection that the information sought will be inadmissable at trial if the information sought appears reasonably calculated to lead to the discovery of admissible evidence.
[37]*37MCR 2.302(B)(1) clearly prohibits discovery of privileged information. We agree with Judge Mackenzie’s dissent in Porter, supra at 627, that “[t]he concept of privilege thus supersedes even the liberal discovery principles of this state.”
The language of § 2157 is clear in its prohibition of disclosure of privileged information. In accordance with prior rulings of this Court, particularly Schechet, that the purpose of the privilege is to encourage patients’ complete disclosure of all symptoms and conditions by protecting the confidential relationship between physician and patient, we find requiring the defendant hospitals to disclose the identity of unknown patients would be in direct contradiction of the language5 and established purpose of the stat[38]*38ute. 6
Historically, confidentiality has been understood to be necessary to promote full disclosure of a patient’s medical history and present medical concerns. See Briesenmeister v Knights of Pythias, 81 Mich 525, 531; 45 NW 977 (1890). As the dissent notes, “information falls within the purview of the physician-patient privilege only if it was ‘necessary’ to enable a physician ‘to prescribe’ for a patient.” Post at 50-51. The dissent goes on to argue that we have disregarded this language and render the language of the [39]*39statute surplusage. However, patients armed with the knowledge that their name may not be kept confidential may not be as willing to reveal their full medical history for fear that, ultimately, that information, too, may lose its confidential status. This chilling of the patient’s desire to disclose would have a detrimental effect on the physician’s ability to provide effective and complete medical treatment and is therefore “necessary” to enable a physician “to prescribe” for a patient.7
A patient may intentionally and voluntarily waive the privilege. See Kelly v Allegan Circuit Judge, 382 Mich 425; 169 NW2d 916 (1969). A patient may also impliedly waive the privilege as specifically provided for with § 2157. However, the patients in the present cases have neither voluntarily nor impliedly waived their right to the privilege. Therefore, this Court’s rationale in Schechet is equally applicable to the present cases. That Court found:
It need only be said that no question of waiver of privilege is before us; . . . that the third party information plaintiff would have disclosed could in no view of the cited rules of court be regarded as “matter not privileged which is admissible under the rules of evidence governing trials,” and that the circuit court erred reversibly in failing to uphold the defendant physician’s right — no duty — to refrain from disclosure .... [372 Mich 350-351.]
m
In Gregory, the trial court ordered the defendant hospital to provide Gregory with any investigative [40]*40reports relative to the incident report; any statements made by any person with respect to the incident; and any notes, memoranda, records, and reports related to the incident. Heritage argues that the incident report, as well as any other information maintained in furtherance of the hospital’s quality assurance and peer review function is protected from discovery by statute.
Two Michigan statutes govern the confidentiality of records, reports, and other information collected or used by peer review committees in the furtherance of their duties. MCL 333.20175; MSA 14.15(20175) addresses a hospital’s duty to keep and maintain records regarding all treatment given to patients at that facility. It also addresses the confidentiality of peer review records. Section 20175(8) provides:
The records, data, and knowledge collected for or by individuals or committees assigned a professional review function in a health facility or agency are confidential, shall be used only for the purposes provided in this article, are not public records, and are not subject to court subpoena.
Further evidence of the Legislature’s intent to fully protect quality assurance/peer review records from discovery is found at MCL 333.21515; MSA 14.15(21515), which provides:
The records, data, and knowledge collected for or by individuals or committees assigned a review function described in this article are confidential and shall be used only for the purposes provided in this article, shall not be public records, and shall not be available for court subpoena.
In Gallagher v Detroit-Macomb Hosp Ass’n, 171 Mich App 761; 431 NW2d 90 (1988), the Court of [41]*41Appeals considered whether an incident report prepared regarding Gallagher’s slip and fall while a patient at South Macomb Hospital could be introduced at trial. The Court of Appeals affirmed the trial court’s ruling refusing to permit Gallagher to introduce the incident report. The Gallagher Court noted that the Public Health Code requires hospitals to engage in reviews of their practices and procedures in an effort to improve the quality of patient care. “To achieve this end, the Legislature has exempted from court subpoena information and records compiled in furtherance of improving health care and reducing morbidity and mortality.” 171 Mich App 768.
Hospitals are required to establish peer review committees whose purposes are to reduce morbidity and mortality and to ensure quality care. MCL 333.21513; MSA 14.15(21513).8 In Attorney General v Bruce, 422 Mich 157, 169; 369 NW2d 826 (1985), this Court stated:
The rationale for protecting the confidentiality of the records, data, and knowledge of such [peer review] committees was set forth in an oft-quoted opinion of the United States District Court for the District of Columbia:
[42]*42“Confidentiality is essential to effective functioning of these staff meetings; and these meetings are essential to the continued improvement in the care and treatment of patients. Candid and conscientious evaluation of clinical practices is a sine qua non of adequate hospital care. To subject the discussions and deliberations to the discovery process, without a showing of exceptional necessity, would result in terminating such deliberations. [Emphasis in original. Bredice v Doctors Hosp, Inc, 50 FRD 249, 250 (D DC, 1970), aff'd without opinion 156 US App DC 199; 479 F2d 920 (1973).]”
Additionally, in Monty v Warren Hosp Corp, 422 Mich 138, 147; 366 NW2d 198 (1985), this Court found that in determining whether the information is privileged, “the court may wish to consider the hospital’s bylaws and internal regulations, and whether the committee’s function is one of current patient care or retrospective review.”
In the present case, defendant Heritage provided the affidavit of Therese Oziemski, Manager of Quality and Utilization Management at Heritage Hospital. According to Ms. Oziemski’s affidavit, the incident report and other investigative documents sought by plaintiff Gregory are used for the purpose of maintaining health care standards at the hospital, improving the quality of care provided to patients, and reducing morbidity and mortality within the hospital.
Hospital personnel are expected to give their honest assessment and reviews of the performance of other hospital staff in incidents such as the one in the present case. Absent the assurance of confidentiality as provided by §§ 21515 and 20175(8), the willingness of hospital staff to provide their candid assessment will be greatly diminished. This will have a direct effect on the hospital’s ability to monitor, investigate, [43]*43and respond to trends and incidents that affect patient care, morbidity, and mortality.
Given that Heritage offered evidence in the form of Ms. Oziemski’s affidavit that the information sought by Gregory was collected for the purpose of retrospective review by the peer committee, the trial court erred in ordering Heritage to produce the incident reports and other related investigatory documents. Gregory was not afforded the opportunity to challenge this evidence regarding whether it was actually collected for the purpose of retrospective review by the peer committee. Therefore, we remand to the trial, court to allow plaintiff to test the veracity of the hospital’s procedures.
IV
Heritage argues that Gregory’s claim that defendant Heritage failed to properly supervise and monitor patients is a medical malpractice action requiring a notice of intent to sue and an affidavit of merit and that the trial court erred in finding that the claim was an ordinary negligence action.
“[A] complaint cannot avoid the application of the procedural requirements of a malpractice action by couching its cause of action in terms of ordinary negligence.” McLeod v Plymouth Court Nursing Home, 957 F Supp 113, 115 (ED Mich, 1997), citing MacDonald v Barbarotto, 161 Mich App 542; 411 NW2d 747 (1987).
In the present case, plaintiff Gregory argues that the claim is an ordinary negligence action and not a medical malpractice action. Therefore, the claim is [44]*44not subject to MCL 600.2912b; MSA 27A.2912(2) or to MCL 600.2912d; MSA 27A.2912(4).
MCL 600.2912b; MSA 27A.2912(2) provides:
(1) Except as otherwise provided in this section, a person shall not commence an action alleging medical malpractice against a health professional or health facility unless the person has given the health professional or health facility written notice under this section not less' than 182 days before the action is commenced.
* * *
(4) The notice given to a health professional or health facility under this section shall contain a statement of at least all of the following:
(a) The factual basis for the claim.
(b) The applicable standard of practice or care alleged by the claimant.
(c) The manner in which it is claimed that the applicable standard of practice or care was breached by the health professional or health facility.
(d) The alleged action that should have been taken to achieve compliance with the alleged standard of practice or care.
(e) The manner in which it is alleged the breach of the standard of practice or care was the proximate cause of the injury claimed in the notice.
(f) The names of all health professionals and health facilities the claimant is notifying under this section in relation to the claim.
MCL 600.2912d; MSA 27A.2912(4) provides:
(1) Subject to subsection (2), the plaintiff in an action alleging medical malpractice or, if the plaintiff is represented by an attorney, the plaintiff’s attorney shall file with the complaint an affidavit of merit signed by a health professional who the plaintiff’s attorney reasonably believes meets the requirements of an expert witness under section [45]*452169. The affidavit of merit shall certify that the health professional has reviewed the notice and all medical records supplied to him or her by the plaintiff’s attorney concerning the allegations contained in the notice and shall contain a statement of each of the following:
(a) The applicable standard of practice or care.
(b) The health professional’s opinion that the applicable standard of practice or care was breached by the health professional or health facility receiving the notice.
(c) The actions that should have been taken or omitted by the health professional or health facility in order to have complied with the applicable standard of practice or care.
(d) The manner in which the breach of the standard of practice or care was the proximate cause of the injury alleged in the notice.
In Bronson v Sisters of Mercy Health Corp, 175 Mich App 647; 438 NW2d 276 (1989), the plaintiff’s complaint included allegations that the defendant hospital had failed to supervise and adequately maintain its staff. The plaintiff argued that the trial court erred in granting summary disposition for failure to file the claim within the two-year period of limitation applicable to medical malpractice claims, because the complaint stated a claim for ordinary negligence only, which is governed by a three-year period of limitation. The Court of Appeals affirmed the trial court’s order of summary disposition, agreeing with the trial court that the allegations within the plaintiff’s complaint involve issues of medical judgment.
The key to a medical malpractice claim is whether it is alleged that the negligence occurred within the course of a professional relationship. The providing of professional medical care and treatment by a hospital includes supervision of staff physicians and decisions regarding selection and retention of medical staff. [175 Mich App 652-653 (citations omitted).]
[46]*46The determination whether a claim will be held to the standards of proof and procedural requirements of a medical malpractice claim as opposed to an ordinary negligence claim depends on whether the facts allegedly raise issues that are within the common knowledge and experience of the jury or, alternatively, raise questions involving medical judgment. Wilson v Stilwill, 411 Mich 587, 611; 309 NW2d 898 (1981); McLeod v Plymouth Court Nursing Home, supra at 115. In Starr v Providence Hosp, 109 Mich App 762, 766; 312 NW2d 152 (1981), the Court of Appeals found that issues involving whether the defendant hospital exercised appropriate supervision in a “special care unit” were “issues involving professional judgments which are beyond the common knowledge and experience of laymen to judge.”
In Waatti v Marquette General Hosp, Inc, 122 Mich App 44, 49; 329 NW2d 526 (1982), the Court of Appeals held that “[w]hether a seizure patient requires constant medical attendance or restraints is an issue of medical management to be established by expert testimony,” citing Wilson v Stilwill and Starr v Providence Hosp, supra.
Count hi of Gregory’s complaint makes the three following allegations:
17. That Defendant Hospital owed a duty to its patients to hire employees who would protect them from other patients with violent propensities and to closely monitor those patients with such propensities.
18. That Defendant Hospital also owed a duty to its patients to have adequate staffing to control the behavior of the patients under psychiatric care at Defendant Hospital.
19. That Defendant breached these duties owed to Plaintiff by having insufficient staff to monitor the behavior of its patients and by allowing patients with violent propensi[47]*47ties to roam around the hospital and enter other patients’ rooms without supervision.
As in Bronson, Starr, and Waatti, these allegations concerning staffing decisions and patient monitoring involve- questions of professional medical management and not issues of ordinary negligence that can be judged by the common knowledge and experience of a jury. The ordinary layman does not know the type of supervision or monitoring that is required for psychiatric patients in a psychiatric ward. Thus, the trial court erred in not requiring that plaintiff provide a notice of intent to sue and an affidavit of merit as required by §§ 2912b and 2912d.
We note that the appropriate sanction for the failure to provide a notice of intent to sue is dismissal without prejudice. See Neal v Oakwood Hosp, 226 Mich App 701, 715; 575 NW2d 68 (1997).
As to the appropriate sanction for failure to file an affidavit of merit, we find in the present case that dismissal without prejudice is also appropriate. In VandenBerg v VandenBerg, 231 Mich App 497, 502; 586 NW2d 570 (1998), the Court of Appeals found that the purpose of the statute was to prevent frivolous medical malpractice claims. In that case, plaintiff did not file an affidavit of merit at the time of filing the complaint; however, the defendants did receive an affidavit of merit at the same time they were served with the summons and the complaint. The Court of Appeals found that defendants did not suffer any prejudice because “they had access to the affidavit of merit from the moment they received the complaint.” Id. at 503. In the present case, plaintiff’s complaint was unaccompanied by an affidavit of merit at the time of filing and service upon the defendant, and at [48]*48no time has plaintiff ever supplemented her complaint with an affidavit of merit. Under these circumstances, we hold that dismissal without prejudice would be the appropriate sanction for plaintiffs failure to comply with § 2912d.
CONCLUSION
We hold that the names of unknown patients are protected by the physician-patient privilege, MCL 600.2157; MSA 27A.2157, and that the defendant hospitals have a duty to refrain from disclosure. The language of MCL 600.2157; MSA 27A.2157 is clear in its prohibition of disclosure of privileged information. Where a patient has neither voluntarily waived the privilege nor impliedly done so as specifically provided within § 2157, there are strong public policy reasons for applying the physician-patient privilege to disclosure of an unknown patient’s name. A patient who fears disclosure may be chilled from seeking medical assistance.
We also hold that the Gregory trial court erred in ordering the defendant hospital to provide plaintiff with any investigative reports relative to the incident report; any statements made by any person with respect to the incident; and any notes, memoranda, records, and reports related to the incident. Defendant argues that this information was collected by the defendant hospital for the purpose of retrospective review by a peer committee and should be protected from discovery pursuant to MCL 333.20175; MSA 14.15(20175) and MCL 333.21515; MSA 14.15(21515). However, because plaintiff was not afforded the opportunity to challenge whether information sought was actually collected for the purpose of retrospec[49]*49tive review by a peer committee, we remand to the trial court to allow plaintiff to test the veracity of defendant hospital’s procedures.
We also hold that the Gregory trial court erred in denying defendant hospital’s motions for summary disposition for plaintiff’s failure to file a notice of intent and for plaintiff’s failure to file an affidavit of merit. The supervision and monitoring of psychiatric patients in a psychiatric ward involves questions of professional medical management and, therefore, cannot be judged by the common knowledge and experience of a jury. Thus, plaintiff Gregory’s claim was one of medical malpractice and subject to MCL 600.2912b; MSA 27A.2912(2) and MCL 600.2912d; MSA 27A.2912(4). Given that plaintiff Gregory failed to comply with these provisions, the trial court erred in not granting the defendant hospital’s motions for summary disposition on this matter.
Accordingly, we affirm the judgment of the Court of Appeals with respect to Dorris v Detroit Osteopathic Hosp. We partially reverse the judgment of the trial court in Gregory v Heritage Hosp and remand the case to that court for proceedings consistent with this opinion.
Weaver, C.J., and Taylor, and Young, JJ., concurred with Brickley, J.
Corrigan, J., concurred with Brickley, J., in Gregory, but took no part in the decision of Dorris.
