OPINION
JACOBSON, Presiding Judge.In this case of first impression in Arizona, we must determine whether a psychiatrist and his employer are liable to the surviving spouse of a person who was killed by an individual who received treatment as an out-patient.
The facts are taken in a light most favorable to the plaintiff-appellant, Laura U. Cooke, against whom summary judgment was entered. In late 1981 and early 1982, Tanya Robinson, a single 22 year old student at the University of Arizona, came to believe that she was the subject of surveillance by the Central Intelligence Agency (CIA). She conveyed this belief to her sister who recommended that she seek help from the Southern Arizona Mental Health Center (SAMHC). SAMHC is a tax-supported public health facility operated by defendant-appellee State of Arizona. See generally A.R.S. § 36-501, et seq. Robinson was first seen at SAMHC on February 11, 1982, by Gypsy Barker Lyle, a social worker, who took a history from Robinson and came to a working diagnosis of “paranoia.” Robinson was seen on February 23, 1982, by defendant-appellee, Dr. Sanford Berlin, a psychiatrist employed as a consultant to SAMHC. Berlin agreed with Lyle’s diagnosis of paranoia and prescribed Navané, an anti-psychotic drug.
On February 26,1982, Robinson was taken off Navane, because of adverse side effects, and Trifluoperazine was prescribed. Robinson was seen on March 9, but cancelled her March 17 and 29 appointments. She was also seen again at the clinic on April 1 and 22, but cancelled her April 9 appointment. She was last seen at the clinic on May 24, 1982.
At the March 9 appointment, Robinson told Lyle that she was now convinced that the CIA was not responsible for the continuing surveillance of herself and home, but that she still felt the surveillance was continuing. Lyle concluded that the surveillance delusion was connected to Robinson’s having been raped in 1981. Although Robinson missed appointments in March, her sister called Lyle and related problems with Robinson not taking her medication and expressing suicidal thoughts. Robinson missed another appointment initiated by Lyle as a result of the sister’s call, but was seen by both Lyle and Berlin on April 1 and 22.
In April, Robinson related to Lyle and Berlin that she now concluded that a Tucson disc jockey, Robert Cooke, was responsible for the surveillance which was being carried on through her radio. With Robinson’s permission, Lyle contacted Cooke to arrange a meeting between the two. Cooke refused. Both Berlin and Lyle at that point felt that there was no likelihood that Cooke was endangered by Robinson’s delusion.
On May 24, 1982, Robinson was seen by Joan Bussanich, a hypnotherapist at SAMHC. Bussanich did not consider Robinson an appropriate candidate for hypnotherapy. Robinson did, however, inform Bussanich that she was going to leave Tucson to get away from Cooke. Bussanich attempted to make another appointment for Robinson to see Lyle on May 25. Although Robinson agreed to call Lyle, she never contacted Lyle or anyone else at SAMHC thereafter. This was the last contact by Robinson with SAMHC.
In early June 1982, Robinson moved to Phoenix, Arizona, and stayed with her sister. In July, she left Arizona and moved to Virginia to live with her grandmother. While in Virginia, Robinson for the first time concluded that the only way she could escape from Cooke’s surveillance was to kill him. She never relayed these thoughts to anyone, until after the fatal shooting.
*222On August 14, 1982, Robinson returned to Tucson, but did not contact her family, friends or anyone at SAMHC. She stole a gun from her parents’ home and on August 22,1982, after waiting for Cooke to leave a bar where he worked as a disc jockey, shot and killed him in a parking lot.
Robinson was subsequently arrested and tried for murder. Pending trial, on petition, she was admitted to Kino Community Hospital where she was again diagnosed as having a paranoid schizophrenic disorder. She was again treated with Navane. She was found not guilty by reason of insanity and was readmitted to Kino on November 22, 1982.
Subsequent testing at Kino revealed several chemical imbalances and a revised diagnosis of “atypical psychosis.” Robinson was treated with anti-depressant medication and her condition improved. On June 22, 1983, Robinson was discharged to SAMHC’s halfway house.
Laura U. Cooke, Robert Cooke’s surviving spouse, commenced this action against the State of Arizona, Berlin and Robinson in Pima County Superior Court. The state sought and was granted a change of venue to Maricopa County pursuant to A.R.S. § 12-824(B).1 The supreme court declined to review this ruling on a special action brought by Berlin, Robinson and Cooke. Robinson subsequently settled with Cooke and was dismissed from this litigation.
The trial court granted the motion of both the state and Berlin for summary judgment. In doing so, it stated:
“IT IS ORDERED granting the Motions for Summary Judgment finding that the defendants owed no duty to the plaintiff that can form a basis of liability, specifically, that SAMHC could not have reasonably foreseen that Tanya Robinson would injure Robert Cooke.
Further, the Court finds a lack of any evidence of negligence on the part of Barker, Bussanich, Berlin or SAMHC.” Laura U. Cooke has appealed.
NEGLIGENCE
Before addressing the issues of duty and foreseeability, we dispose of the trial court’s contention that Cooke failed to present any evidence of negligence on the part of Berlin or SAMHC.2 In doing so, we focus on what Cooke contends are the negligent acts giving rise to the alleged liability in this case.
Appellant’s allegations of negligence are derived primarily from the opinion of her expert, Dr. Wesley A. McEldoon. Basically, Dr. McEldoon found fault with SAMHC’s “system” of having social workers perform the work of a physician. As Dr. McEldoon testified:
I mean, I think there is a real fault in the entire system, any system that would take a person without medical training [Gypsy Baker Lyle] and make them responsible for the diagnosis and medical care of a person that might present to them, any system that puts a non-physician in that position is doing a disservice.
******
Q: Let me understand. Are you saying that Gypsy was not qualified to take the initial information and make a diagnosis?
A: That’s right.
******
Q: So once again you think the system is bad because it doesn’t have qualified people, is that what you’re saying?
A: Basically, yes.
Q: And you would remedy that by having people with what qualifications again?
A: I would have physicians doing physician [sic] work. I certainly wouldn’t have social workers doing physician [sic] work.
Q: That would cost more money, wouldn’t it?
*223A: Certainly.
Q: That’s one of the problems, isn’t it?
A: That’s one of the problems.
In addition, Dr. McEldoon concluded that Berlin fell below the applicable standard of care by not re-evaluating the initial misdiagnosis and thus correcting a misguided treatment plan. In Dr. McEldoon’s opinion if SAMHC and Berlin had not acted negligently in this case, Robinson would have been cured and thus would not have killed Cooke.
In our opinion, this testimony, at least at the summary judgment stage, is sufficient to raise a material issue of fact as to whether the “system” established by the state to render mental health care was deficient, and whether Berlin’s treatment of Robinson fell below the applicable standard of care.
We also reject the state’s argument that assuming arguendo that Berlin was negligent, the state would not be vicariously liable because Berlin was an independent contractor. We reject this argument for two reasons. First, even if Dr. Berlin were an independent contractor, it appears that the state undertook to provide a nondelegable duty to provide adequate care. See DeMontiney v. Desert Manor Convalescent Center, 144 Ariz. 6, 695 P.2d 255 (1985). Second, the appellant has alleged independent negligence of the state in allowing non-physicians to perform work which in the opinion of Dr. McEldoon can only be performed by a physician. Dr. McEldoon was qualified to render such an opinion.
We therefore conclude that the appellant for the purposes of avoiding summary judgment, has raised an issue of fact concerning appellees’ failure to meet an appropriate standard of care, in the diagnosis and treatment of Robinson’s mental condition.
DUTY
Having concluded that appellees may have been negligent in the diagnosis and treatment of Robinson, the question remains whether such negligence gives rise to any liability for Robinson’s killing of Robert Cooke. In focusing on this issue it is important to state what theories are not espoused by the appellant. The appellant does not contend that the appellees had a duty to warn Robert Cooke that Robinson posed a threat to him, as there is no evidence that the appellees knew that Robinson had formed an intent to harm Cooke. See Tarasoff v. Regents of University of California, 17 Cal.3d 425, 131 Cal.Rptr. 14, 551 P.2d 334 (1976). It is clear that this intent, according to Robinson, was not formed until she was in Virginia, some two months after she was last seen at SAMHC. It is equally clear that this intent was never voiced by Robinson to anyone prior to the shooting.
Also, the appellant does not contend that the appellees had a duty to confine Robinson. See generally Restatement (Second) of Torts § 319 (1965). Again, it is conceded that at the time Robinson was under treatment by SAMHC she was not committable under A.R.S. § 36-529(B) as posing a danger to herself or to others.
Appellant does, however, assert that SAMHC and Berlin owed a duty to any third party foreseeably at risk from the negligent diagnosis and treatment of Robinson.
In analyzing this duty issue we start with the recognized concept that “a negligence action may be maintained only if there is a duty or obligation, recognized by law, which requires the defendant to conform to a particular standard of conduct in order to protect others against unreasonable risks of harm.” Markowitz v. Arizona Parks Board, 146 Ariz. 352, 354, 706 P.2d 365, 366 (1985). In making this legal determination we heed the admonition of the Arizona Supreme Court not to equate the concepts of duty with specific details of conduct. Coburn v. City of Tucson, 143 Ariz. 50, 691 P.2d 1078 (1984).3 We there*224fore are presented with the broad question of whether any person has the duty to control the conduct of a third person so as to prevent harm befalling another. The answer to this question is a qualified no, as there is no common-law duty to control the acts of another. Davis v. Mangelsdorf, 138 Ariz. 207, 673 P.2d 951 (App.1983); Restatement (Second) of Torts, § 314 (1965). See generally Harper & Kime, The Duty to Control the Conduct of Another, 43 Yale L.J. 886 (1934).
The Restatement (Second) of Torts § 315 (1965) reflects the general rule of nonliability and its exceptions:
There is no duty so to control the conduct of a third person as to prevent him from causing physical harm to another unless
(a) a special relation exists between the actor and the third person which imposes a duty upon the actor to control the third person’s conduct, or
(b) a special relation exists between the actor and the other which gives to the other a right to protection.
We can dispose of the exception stated in Restatement § 315(b) rather summarily. This exception would require a relationship to exist between appellees and Robert Cooke which would give Cooke a right to protection. At the risk of looking at specific conduct to establish that relationship, the only contact between SAMHC and Cooke was a telephone call from Lyle to Cooke requesting his participation in Robinson’s treatment. We finding nothing in this brief contact which would give rise to any obligation to afford Cooke protection, absent a specific threat by Robinson. See Tarasoff v. Regents of University of California, supra.
We turn then to the exception stated in Restatement § 315(a), dealing with the existence of a special relationship which imposes a duty to control. As stated in the comment (c), Restatement (Second) of Torts § 315: “[t]he relations between the actor and a third person which require the actor to control the third person’s conduct are stated in §§ 316-319.” These relationships are: (1) the duty of a parent to control the conduct of a child (§ 316); (2) the duty of a master to control the conduct of a servant (§ 317); (3) the duty of a possessor of land or chattels to control the conduct of a licensee (§ 318); and (4) duty of those in charge of persons having dangerous propensities to control those persons (§ 319). All of these relationships share the common characteristics of the actor’s ability and obligation to control the conduct of the third party. Seibel v. City and County of Honolulu, 61 Hawaii 253, 602 P.2d 532 (1979).
The appellant argues, however, that regardless of the existence of these control characteristics, the psychiatrist-patient relationship is sufficient, in and of itself, to give rise to duty to control, citing Lipari v. Sears, Roebuck & Co., 497 F.Supp. 185 (D.Neb.1980); Petersen v. State, 100 Wash.2d 421, 671 P.2d 230 (1983).
In our opinion, the majority and better reasoned cases which have addressed the psychiatrist-patient relationship have concluded that the duty to control should not be imposed solely because of that relationship. See Abernathy v. United States, 773 F.2d 184 (8th Cir.1985); Anthony v. United States, 616 F.Supp. 156 (D. Iowa 1985); Hasenei v. United States, 541 F.Supp. 999 (D. Maryland 1982); Bradley Center, Inc. v. Wessener, 161 Ga.App. 576, 287 S.E.2d 716 (1982); Cartier v. Long Island College Hospital, 490 N.Y.S.2d 602, 111 A.2d 894 (1985).
The record indicates that the relationship between the appellees and Robinson was completely bereft of any right, opportunity or ability to control her conduct. In this regard, the district court in Hasenei, supra held that:
[t]he typical relationship existing between a psychiatrist and a voluntary outpatient would seem to lack sufficient elements of control necessary to bring such relationship within the rule of § 315. Indeed, lack of control by the therapist and maximum freedom for the patient is oft*225times the end sought by both the psychiatric profession and the law.
Hasenei v. United States, 541 F.Supp. 999, 1009 (1982).
The appellant contends, however, that the necessary “control” for purposes of Restatement § 315, can be analogized from the duty owed by physicians to persons other than their patients for failing to diagnose or warn of contagious or infectious disease, Skillings v. Allen, 143 Minn. 323, 173 N.W. 663 (1919), or failing to warn of the side effects of prescribed medication, Duvall v. Goldin, 139 Mich.App. 342, 362 N.W.2d 275 (Mich.App.1984), or failing to warn a patient who suffers seizures not to drive an automobile, Freese v. Lemmon, 210 N.W.2d 576 (Iowa 1973). Whatever may be said about the legal analysis applied in these cases, they are not § 315 “control” cases. This clear distinction was recognized in Gooden v. Tips, 651 S.W.2d 364 (Tex.Civ.App.1983), in imposing a duty upon a physician for failing to warn the patient/driver of the side effects of prescribed medication:
... We point out that we do not hold that a duty arose on the part of Dr. Tips to control the conduct of his patient as was imposed in cases such as Tarasoff v. Regents of University of California, 17 Cal.3d 425, 131 Cal.Rptr. 14, 551 P.2d 334 (1976); McIntosh v. Milano, 168 N.J.Super. 466, 403 A.2d 500 (1979); Lipari v. Sears Roebuck & Co. 497 F.Supp. 185 (D.Neb.1980); and Bradley Center, Inc. v. Wessner, 161 Ga.App. 576, 287 S.E.2d 716(1982)____ We hold only that, under the facts here alleged, Dr. Tips may have had a duty to warn his patient not to drive. We do not hold that he had a duty to prevent her from driving, if she so desired.” (emphasis in original.)
651 S.W.2d at 370.
This becomes more than simply a game of semantics, for if the psychiatist-patient relationship does not fall within the “control” exception of § 315(a), we are left with the general common law rule that no duty exists to control the conduct of a third person from causing harm to another.
Where, then, do the “non-control” contagious disease and failure to warn of medication cases fall? In our opinion we should determine whether the policy decisions which gave rise to the imposition of a duty in those cases apply with equal force in this case. In discussing this duty issue, we are mindful that:
[d]uty is not sacrosanct in itself, but only an expression of the sum total of those considerations of policy which lead the law to say that the particular plaintiff is entitled to protection.
Prosser, Law of Torts, 3d. Ed. at 332-333 (1964).
“Those considerations of policy” which have been articulated by the courts and commentators are: (1) the foreseeability of harm to the plaintiff flowing from the defendant’s act, (2) the degree of certainty that the plaintiff suffered injury, (3) the “closeness” of the connection between the defendant’s conduct and the injury suffered, (4) the moral blame attached to the defendant’s conduct, (5) the policy of preventing future harm, (6) the burden on the defendant and to the community of imposing a duty to exercise due care, and (7) the availability, cost and prevalence of insurance to cover the risk. Tarasoff v. Regents of University of California, 17 Cal.3d 425, 131 Cal.Rptr. 14, 551 P.2d 334 (1976).
The contagious and infectious disease cases, when applying these policy considerations, conclude that a duty is imposed upon a physician who attends patients afflicted with contagious or infectious disease not to negligently do any act that would tend to spread the disease, because:
[t]he health of the people is an economic asset. The law recognizes its preservation as a matter of importance to the state____ The laws ... have been framed to protect the people, collectively and individually, from the spread of communicable diseases.
Skillings v. Allen, 143 Minn. 323, 173 N.W. 663 (1919).
Thus, the physician’s failure to exercise due care in the diagnosis and treatment of known contagious diseases will result in *226immediate and foreseeable consequences to the health of the public at large.
Likewise, the failure to warn of the side effects of medication or results of disorder cases may be harmonized by looking to duty concepts imposed by Restatement (Second) Torts § 311 (imposing liability for harm caused by negligently giving false information upon which another can reasonably rely). See concurring opinion of Justice Uhlenhopp in Freese v. Lemmon, supra.
In our opinion, applying these policy considerations militates against a finding of a duty to control based solely on the psychiatrist-patient relationship. First, it is conceded by Dr. McEldoon that Tanya Robinson at the time she was under the care of the defendants, posed no threat to Robert Cooke and thus the harm suffered by Cooke was not foreseeable. Second, the connection between the defendants’ alleged conduct (failure to diagnose and successfully treat) and the shooting of Robert Cooke is remote. This is true not only from a causation standpoint, but also from a time and distance standpoint. The determination by Robinson to kill Cooke was formed some three months after she had unilaterally terminated treatment and while she was in Virginia. Third, imposing liability in this case will not ensure that the treatment and diagnosis of the mentally ill will improve. This is for the simple reason that the ability to diagnose dangerousness and thus control or treat it simply is not that accurate. As was noted by Schopp and Quatrocchi in Tarasoff, The Doctrine of Special Relationships and the Psychotherapist’s Duty to Warn, Journal of Psychiatry and Law 13, 23 (Spring 1984).
[u]nfortunately, a rather large and consistent body of empirical evidence indicates that the standards of the profession include no ability to accurately predict dangerous behavior. Not only have psychologists and psychiatrists been unable to predict dangerousness to a degree of accuracy which would justify infringing upon a client’s rights, they have been unable to predict any more accurately than have nonprofessionals.
In our opinion, the essence of the duty problem, and our concern, was aptly captured in Brady v. Hopper, 570 F.Supp. 1333 (D.Colo.1983). In Brady, the plaintiffs were injured by John W. Hinckley, Jr. in Hinckley’s attempt to assassinate President Reagan. The suit alleged, in part, that Hinckley’s psychiatrist had negligently diagnosed and treated him. The Brady court held that the psychiatrist owed no duty to plaintiffs because Hinckley had not made specific threats against a readily identifiable victim. 570 F.Supp. at 1339. In so holding, the court stated that:
[t]o impose upon those in the counseling professions an ill-defined ‘duty to control’ would require therapists to be ultimately responsible for the actions of their patients. Such a rule would closely approximate a strict liability standard of care, and therapists would be potentially liable for all harm inflicted by persons presently or formerly under psychiatric treatment. Human behavior is simply too unpredictable, and the field of psychotherapy presently too inexact to so greatly expand the scope of therapist’s liability. In my opinion, the ‘specific threats to specific victims’ rule states a workable, reasonable and fair boundary upon the sphere of the therapist’s liability for the acts of their patients.
570 F.2d at 1339.
We agree with the holding in Brady. In reaching this conclusion, we are cognizant of the considerations of policy which govern creation or negation of the duty of a psychiatrist toward others when diagnosing and treating a third person. Having reviewed these considerations of policy, we conclude that in the instant case no duty may run from the appellees to plaintiff’s decedent absent a showing of a specific threat to a specific victim.
VENUE
A.R.S. § 12-822(B) mandates that upon written demand of the attorney general, the place of trial of any action against the state in contract or negligence actions shall be changed to Maricopa County. The provision is mandatory. Additionally, *227when a change of venue has been made pursuant to A.R.S. § 12-822(B) and the state remains a party, the action is not subject to the venue provisions of A.R.S. § 12-406. Johnson v. University Hospital, 148 Ariz. 37, 712 P.2d 950 (App.1985). Appellant argues that our opinion in Johnson should be reconsidered. We decline to do so.
Appellant also argues that assuming that A.R.S. § 12-822(B) is controlling, the statute is unconstitutional in that it is violative of the due process and equal protection clauses of the federal and state constitutions. As previously stated in Johnson v. University Hospital, we read the Arizona Supreme Court decision in State v. Superior Court, 120 Ariz. 273, 585 P.2d 882 (1978) as, at least impliedly, upholding the constitutionality of § 12-822(B). 148 Ariz. at 43, 712 P.2d at 956. See also Gila Valley Irrigation District v. Superior Court, 144 Ariz. 288, 697 P.2d 681 (1985). This court lacks authority to disaffirm prior decisions of the Arizona Supreme Court. Johnson v. University Hospital, 148 Ariz. at 43, 712 P.2d at 956. Consequently, we do not address the constitutionality issue.
Judgment affirmed.
CONTRERAS, J., concurs.. A.R.S. § 12-824(B) was renumbered as A.R.S. § 12-822(B) by Law, 1984, ch. 285 § 7. This statute in essence requires that upon written demand of the Attorney General, any action against the State of Arizona shall be transferred to Maricopa County for trial.
. On appeal, appellant does not contend that either Lyle or Bussanich are individually liable.
. We find this admonition somewhat difficult when attempting to define foreseeability as an element of duty, for we are at a loss to see how foreseeability can be viewed in the abstract. See Palsgraf v. Long Island Railroad Co., 284 N.Y. 329, 162 N.E. 99 (1928), adopted in Arizo*224na, West v. Cruz, 75 Ariz. 13, 251 P.2d 311 (1952).
