This is an appeal from a judgment by Judge Goettel of the Southern District holding that New York State has been violating the fourteenth amendment by returning mental patients from hospital to prison without adequate procedural protections. We conclude that the inmates have not been deprived of due process or subjected to cruel and unusual punishment and accordingly we reverse.
I
State prison inmates adjudged in need of institutional care for mental illness are sent to Matteawan State Hospital, which is part of a medium-security facility in Beacon, New York.1 Although New York law provides elaborate procedural protections prior to involuntary transfers from prison to mental hospital, there are no statutory procedures mandated for transfers back to prison.2 In October 1975 patients and former patients at Matteawan brought a class action alleging that transfers from the hospital back to prison had violated their rights under the due process clause and under state law. That winter, five of the plaintiffs and seven Matteawan physicians testified at four days of hearings. Judge Goet-tel’s findings are set forth in his opinion at 424 F.Supp. 1277.
The transfer decisions are made only after evaluations. An evaluation of each patient at Matteawan is conducted by a staff psychiatrist every month or two. The interview lasts roughly twenty minutes, after which the doctor spends a few minutes writing down his observations and recommendations as to treatment. Although a number of evaluations used to be performed by psychiatrists who had not had any significant prior exposure to the particular patient, since the spring of 1974 it has been the hospital practice for each evaluation normally to be conducted by the ward doctor who has been responsible for the patient’s treatment. In some wards, the doctor conducts his evaluations on a team basis, in consultation with other members of the ward staff.
The examiner has access to the patient’s commitment papers, reports of previous evaluations, and reports of any major disturbances. It appears that informal notes are sometimes made by treating psychia*660trists, correctional officers, social workers, and nurses, but such notes are kept to a minimum for confidentiality purposes and it is not clear that they are ordinarily consulted by the interviewer.
The evaluation procedure is flexible. Sometimes more than one psychiatrist may interview the patient; if the examining psychiatrist has not been the one responsible for the patient’s treatment, the treating physician will sometimes set forth his own opinion in a letter. Written recommendations may also be offered by other members of the patient’s ward team. Evaluations may be scheduled out of turn if there is some reason why a prompt decision in his case seems desirable.
If the evaluating psychiatrist recommends a return to prison, his report is reviewed by the hospital’s chief of psychiatric services, Dr. Lawrence Sweeney. Defendant Sweeney testified that he had personal knowledge of many of the hospital’s patients whom he saw on his tours of the wards, and that on occasions he had disagreed with an interviewer’s conclusions and had asked for another evaluation.
Although the hospital has no formal written or oral guidelines on when a patient should be returned to prison, the doctors testifying seemed to be in general agreement about the principal criteria. They identified the crucial questions as whether the patient is in contact with reality and reacts to the world in a rational manner, and whether his condition may be improved through further hospitalization. The borderline cases are patients who are not psychotic but have neuroses, personality disorders, or other psychological problems which some psychiatrists believe are treatable and some not, and which may or may not be aggravated by a return to prison. Several of the doctors testified that because of uncertainties in following up on patients after their return to prison and concern about the destructiveness of the prison environment, they tend to let borderline patients stay on at Matteawan somewhat longer than would otherwise be medically mandated. However, if such a patient becomes disruptive and potentially dangerous to other patients and hospital personnel, or if he tries to take advantage of the relatively low security at the hospital in order to escape, the doctors may conclude that it would be better for him to be back in prison where he can be more readily controlled. Thus, if a patient’s involvement in a fight is considered not to be a symptom of mental illness, it can result in his being transferred to prison.
Relying primarily on their own experiences, the plaintiffs contended at trial that a number of transfer decisions were being made arbitrarily, out of spite, or simply as punishment for misbehavior. Plaintiffs Gully and Cruz were first admitted to Mat-teawan in January 1974 after attempts at suicide. Plaintiff Poveromo was admitted in September 1974. Gully and Poveromo were returned to prison shortly after they were involved in a fight in their ward in January 1975. Within a few weeks (during much of which time they were confined in stripped cells), the prison authorities sent them back to Matteawan. Gully and Cruz were involved in another fight in October 1975, and after the incident they were evaluated by a group of six staff psychiatrists while in restraining sheets, and thereafter returned to prison.
Plaintiff Dunleavy arrived at Matteawan in April 1974. A year later, and six weeks after a brief escape from the hospital, he was returned to prison. Within a month, he slashed his wrists and was returned to Matteawan.3
Plaintiff Mitchell arrived at Matteawan in September 1974. On October 10,1975 he was evaluated by a staff psychiatrist who diagnosed him as recovered. When told by a corrections officer that he was to be transferred back to prison, Mitchell “went beserk” and had to be placed in a strait jacket. According to Mitchell’s testimony, he attempted suicide several times while waiting to be returned to prison, but the transfer was nevertheless carried out. Af*661ter two weeks at prison, he was returned to Matteawan.
The district court concluded that the procedures being followed to protect patients’ right to treatment were unsatisfactory.4 Judge Goettel found that the decisions to transfer the plaintiffs had “very likely” been “foregone conclusions in light of the plaintiffs’ prior problems with correctional officers.” He determined that, at a minimum, due process must include written notification to the inmate of the transfer decision and its factual basis, identification of the decision-makers, and review of the transfer decision by a professional who is not a member of the hospital staff.5
II
We disagree with the district court’s assessment of the requirements of procedural due process and conclude that no violation has been demonstrated in this case.6 Nor do we think the plaintiffs have suffered cruel and unusual punishment.
The ingredients of due process depend on the interests at stake and the nature of the issues to be resolved. See generally Note, Specifying the Procedures Required by Due Process: Towards Limits on the Use of Interest Balancing, 88 Harv.L. Rev. 1510, 1514 (1975). Due process does not require formal hearings and inflexible guidelines under all circumstances. See Cafeteria Workers Union v. McElroy, 367 U.S. 886, 894-95, 81 S.Ct. 1743, 6 L.Ed.2d 1230 (1961); Haymes v. Regan, 525 F.2d 540 (2d Cir. 1975).
[Identification of the specific dictates of due process generally requires consideration. of the private interest that will be affected . . . , the risk of an erroneous deprivation of such interest . .■ . and the probable value, if any, of additional . . . procedural safeguards, and, finally, the government interest, including the function involved and the fiscal and administrative burdens that the additional procedural requirement would entail.
Mathews v. Eldridge, 424 U.S. 319, 335, 96 S.Ct. 893, 903, 47 L.Ed.2d 18 (1976).
Another constraint on state actions affecting the health of prisoners is the prohibition against cruel and unusual punishments. Because an ill inmate must rely on his warder’s aid, the state has a duty to supply him with medical care. Estelle v. Gamble, 429 U.S. 97, 103, 97 S.Ct. 285, 50 L.Ed.2d 251 (1976). Deliberate indifference to a prisoner’s serious medical needs vio*662lates the eighth amendment. Id. at 103-06, 97 S.Ct. 285. Such indifference may occur on an individual level, such as when a doctor intentionally mistreats an inmate, see id. at 104 n. 10, 97 S.Ct. 285, or on an institutional level, when the prison’s system of medical care is so seriously inadequate as to cause unwarranted suffering, see Bishop v. Stoneman, 508 F.2d 1224, 1226 (2d Cir. 1974); Todaro v. Ward, 431 F.Supp. 1129 (S.D.N.Y.1977).
In the present case, the record does not support a finding that transfer decisions have been made in bad faith, out of pique, or on irrational grounds. Proof that a few patients who were transferred from the hospital were returned to it shortly thereafter does not mean that these patients have been unfairly treated. No psychiatrist is a clairvoyant; some diagnoses that are perfectly defensible at the time will, in retrospect, turn out to be erroneous. Also, since many psychological judgments are highly subjective, it is to be expected that prison physicians should sometimes disagree with the opinions of the hospital staff.
Although it would clearly be cruel and unusual to deprive a patient of needed psychiatric care simply in order to punish him for misconduct, the record in this case does not indicate that the transfers were punitive. A few inmates who had been at the hospital for a number of months and whose need for continued hospitalization was considered questionable were transferred to prison shortly after they became embroiled in fights or attempted to escape. When an inmate abuses in this manner the relative freedom afforded him in the hospital environment and threatens the welfare of other patients and hospital personnel, it is clearly appropriate for the staff to reassess his mental condition in order to determine whether continued treatment at the hospital is truly necessary for him or unduly hazardous to others. Thus, it would be too speculative for the district court to presume that these particular transfer decisions were punitive or otherwise contrary to reasonable medical standards.
The nature of the medical judgments involved in this case and the context in which they are made render them peculiarly unsuited to procedural structuring by a court. Compared with other fact-finding processes, the practice of psychotherapy is highly subjective. Since two qualified psychotherapists examining the same patient can reach different conclusions as to malady and cure without either conclusion being demonstrably incorrect, diagnostic consensus is an elusive and sometimes illusory goal. The decision to dehospitalize an inmate is made by a trained physician who is involved in the day-to-day treatment at the hospital, and it is reviewed by the hospital’s chief psychiatrist. Under these circumstances, the marginal value of a third professional opinion seems questionable. The arguments in favor of requiring review by outside parties are weaker here than in the commitment context, cf. United States ex rel. Schuster v. Herold, 410 F.2d 1071 (2d Cir.), cert. denied, 396 U.S. 847, 90 S.Ct. 81, 24 L.Ed.2d 96 (1969), since here the patient has been subject to protracted observation by the hospital treatment staff. In making their evaluations the doctors have recourse to the records of prior evaluations which have accumulated over the course of the patient’s stay; in most cases, they will have participated in the patient’s treatment. Thus, they are in an especially good position to reach an informed conclusion about the patient’s condition. In addition, keeping the evaluation process flexible and informal may enhance the opportunities for input from other staff members.
A statement of reasons and assistance of counsel prior to transfer might do more harm than good. These safeguards, designed for traditional fact-finding and dispute resolution, are much less functional where the issue is whether a doctor thinks his patient requires further treatment. There is also a danger that both these devices could prove to be antitherapeutic in many cases. Moreover, too much concern about precedent may interfere with the effective exercise of administrative and medical discretion. For example, the hospital *663appears to have the capacity to allow a few patients like plaintiff Dunleavy to stay on beyond their normal return dates simply because they are happier at the hospital and they serve a useful liaison function with the other patients; however, if forced to formalize this transfer policy, the hospital might be hardpressed to devise a workable rule. Finally, in view of our concern about unnecessary hospitalization for mental illness, see, e. g., O’Connor v. Donaldson, 422 U.S. 563, 95 S.Ct. 2486, 45 L.Ed.2d 396 (1975); United States ex rel. Schuster v. Herold, supra, 410 F.2d at 1078-79, 1087, we should hesitate before erecting additional procedural obstacles to stand in the way of the termination of such hospitalization.
We also have trouble with the district court’s requirement that in every case the inmate be given notice of his impending transfer. A possible problem with advance notice is that an inmate who knows he is about to be returned to prison may, in the words of defendant Sweeney, “go back to his ward and blow his stack and get everybody else upset.” Whether such notice would substantially enhance the decision-making process or ease the trauma of adjustment for the transferred inmate is a matter of conjecture. Clearly, however, the pros and cons of notice policy are a subject that is better left to the judgment of the doctors at the hospital.
The proposal that the hospital be required to promulgate guidelines suffers from similar infirmities. Since the basic criteria already being applied by the doctors seem fairly sound and uniform, see pages 4400-4401 supra, we doubt that written guidelines will serve much point. On the other hand, discouraging minority views among the staff may in some circumstances be harmful; formal guidelines may carry with them the evils of rigidity. Thus, we conclude that the net benefits which might accrue from these additional procedural safeguards are much too uncertain to warrant a finding that their implementation is mandated as a matter of due process.
Accordingly, the order of the district court is reversed and the case is remanded with instructions that plaintiffs’ complaint be dismissed.7
. At Matteawan, roughly 300 patients were housed in twelve wards. In 1971 the hospital staff included fifteen psychiatrists; by 1975 the number was seven. Limited psychiatric services were also available at each of the other state prisons. New York’s state prison population is approximately 17,000.
Pursuant to recent New York legislation, responsibility for treatment of mentally ill inmates shifted from the department of correctional services to the department of mental hygiene as of April 1, 1977. The new legislation also calls for the establishment of small mental health centers to provide outpatient services at a number of state prisons. N.Y. Corrections Law § 401 (McKinney Supp.1976).
. Commitments are governed by N.Y. Corrections Law § 402 (McKinney Supp.1976), which is substantially a recodification of what used to be N.Y. Corrections Law § 408 (McKinney Supp.1975). If a prison physician believes an inmate is “mentally ill,” a judge will appoint two outside physicians to make an independent examination. § 402, fl 1. After the examination, five-days notice must be served on the prisoner and on his nearest relative or a friend. Id. 1] 3. A hearing may be required on behalf of the inmate, and the judge has discretion to examine the inmate for himself. Id. 1] 5. The person committed also has a right ultimately to a jury trial on the question of his mental illness. Id. 1! 10. Under § 410 of the old law, a patient could be returned to prison only upon certification by the superintendent of Matteawan that he had “recovered.” This purely formal requirement has not been abolished.
. According to an article in The New York Times on May 22, 1977, at page 35, Dunleavy has again escaped from Matteawan, along with Poveromo and numerous other prisoners.
. In a similar case, Burchett v. Bower, 355 F.Supp. 1278 (D.Ariz.1973), the district court reached basically the same result as that reached by the district court here. Pretransfer procedures were also required by the court in Romero v. Schauer, 386 F.Supp. 851 (D.Colo. 1974) (three-judge court), but that case is distinguishable since (1) it involved transfers to prison of mental hospital patients who had never been sentenced to prison and (2) the transfers were based not on a finding that the patients no longer needed treatment but rather on a finding that they were so insane as to be too dangerous for continued confinement at the hospital.
. For purposes of framing injunctive relief, Judge Goettel has asked the defendants to submit proposed procedures to him. We need not reach the question whether his decision as it stands at present is appealable as a final order, see generally Arthur v. Nyquist, 547 F.2d 7 (2d Cir. 1976); Hart v. Community School Board, 497 F.2d 1027, 1031-32 & n. 4 (2d Cir. 1974), since certification and leave to appeal under 28 U.S.C. § 1292(b) have been granted.
. In reaching its decision, the district court . interpreted New York law as granting prison inmates a right to adequate psychiatric treatment. Cf. Kesselbrenner v. Anonymous, 33 N.Y.2d 161, 167, 350 N.Y.S.2d 889, 893, 305 N.E.2d 903 (1973), rev’g 39 App.Div.2d 410, 334 N.Y.S.2d 738 (1972); Dunleavy v. Wilson, 397 F.Supp. 670, 673 (S.D.N.Y.1975). Appellants take issue with this finding, and they argue that inmates who have no legally protected liberty or property interest in receiving psychiatric treatment are not entitled to due process prior to the termination of their hospital stay, see Meachum v. Fano, 427 U.S. 215, 96 S.Ct. 2532, 49 L.Ed.2d 451 (1976). Appellees defend the district court’s interpretation of New York law and contend that, in any event, the right to procedural due process is triggered by a prisoner’s eighth amendment entitlement to adequate medical care. Since we find the state’s existing procedures to be constitutionally adequate, we do not reach any of these other questions.
. Appellees contend that inmates have been returned to prison because of their involvement in organizational activity and litigation. The only testimony regarding any alleged first amendment violations, however, was that one staff psychiatrist told plaintiff Dunleavy he might be transferred if he continued to be involved in litigation. As Dunleavy has remained both in this law suit and in the hospital, it seems clear that any threat against him has not chilled the exercise of his rights and has not been carried out. Accordingly, we do not think the record supports appellees’ request for a remand on this claim.
