Dayton Appeals Court: Kettering Behavioral Hospital Must Face a Jury Over Patient Attack

Published May 19, 2026 · Ohio Appeals Courts

When a family brings a loved one to a psychiatric hospital, they are trusting the staff with that person's safety, including safety from other patients. On April 24, 2026, the Second District Court of Appeals in Dayton held that a young woman who was assaulted by another patient at Kettering Health Behavioral Medical Center is entitled to have a jury hear her case.

The decision, Helton v. Kettering Medical Ctr., 2026-Ohio-1476, reverses a Montgomery County ruling that had ended the case before trial. It also sends a clear message about how far an immunity statute can stretch when a hospital's own safety precautions are not followed.

What the court described

The facts below come from the appeals court's opinion, which describes the evidence in the light most favorable to the patient, as courts must at the summary-judgment stage. Nothing has yet been decided by a jury.

In September 2021, the plaintiff was an 18-year-old inpatient receiving mental health treatment at the facility. That same day, a man was involuntarily admitted with a documented history of sexually aggressive behavior. He had been sexually aggressive in the emergency department and was considered at high risk of harming others. The hospital had policies for high-risk patients, including one-to-one staff monitoring.

On the unit, the man continued to behave aggressively toward women, including staff and other patients. The nurse on duty moved him to a separate, lockable hallway, alerted all staff that he was a threat to female patients, and instructed that a staff member stay with him whenever he was out of his room.

According to the opinion, security video then showed another nurse open the locked door and let the young woman into that hallway, where the man was standing, and close the door behind her. He assaulted her. When she tried to leave, the door was locked. A nurse who heard her screams helped her escape. The man was later arrested and convicted of sexual-imposition offenses. The opinion states that no staff member documented the event in her medical record or notified her treating physician, and that she was discharged afterward.

How the hospital won in the trial court

The patient sued in 2023 for negligence, negligent training and supervision, and related claims, and sought punitive damages. The trial court had already found there was enough evidence for a jury to consider punitive damages.

Then, two weeks before the January 2025 trial date, and roughly fifteen months into the case, the hospital asked for permission to add a new defense: immunity under R.C. 2305.51(B). That statute says a mental health organization can be held liable for failing to protect others from a patient's violence only if an explicit threat of imminent, serious physical harm to one or more clearly identifiable potential victims was communicated to the organization, and the organization then failed to take certain protective steps. The trial court allowed the late defense, postponed the trial, and granted summary judgment to the hospital because the attacker never made an explicit threat against this particular patient.

Why the Second District reversed

The appeals court disagreed on both points.

The late defense. The court explained that R.C. 2305.51(B) is not an affirmative defense that the hospital must plead. The patient bears the burden of proving its conditions as part of her own case. Treating it as a brand-new defense two weeks before trial, after discovery had closed and after the patient had spent considerable time and money preparing, was unnecessary and prejudicial, and allowing the amendment was an abuse of discretion. Courts are increasingly unwilling to let defendants spring defenses at the last minute; the Supreme Court of Ohio made a similar point about cities and immunity last year, as we discussed in our post on late immunity defenses.

The "explicit threat" requirement. The trial court read the statute to require a threat aimed at this patient by name. The Second District called that interpretation too narrow. The evidence showed the man had already assaulted other women on the locked unit, and staff had identified him as a threat to every female patient and put precautions in place for that reason. Although he never threatened the plaintiff by name, she was, in the court's view, a clearly identifiable potential victim. At a minimum, there were genuine questions of fact for a jury.

The court also explained the purpose of the statute. It is meant to protect mental health providers when a patient's violence is not reasonably foreseeable or is beyond the facility's reasonable control. Here, the evidence was that staff predicted the danger, warned about it, and set up precautions, but allegedly failed to carry them out. That is not the situation the immunity was written for.

The case was sent back to Montgomery County for trial on the patient's claims.

What this means for families

Psychiatric and behavioral health units care for people at their most vulnerable. Ohio law protects providers from liability for violence they could not foresee. It does not, under this decision, give a facility a pass when its own staff recognized a threat and the safety plan broke down.

Several lessons from Helton apply to any case against a hospital or residential facility:

• Internal policies matter. The hospital's own monitoring rules and the charge nurse's instructions were central evidence of what the facility knew.
• Video and records are critical, and they do not last. Security footage and staffing records should be requested and preserved immediately. Our guide chapter on preserving documents and records explains how.
• Missing documentation is itself evidence. The opinion noted that the incident was not recorded in the patient's chart. When a facility's records are silent about something serious, that silence can matter.
• Defendants will look for procedural escapes. Having a lawyer involved early helps keep the case focused on what happened, not on technical maneuvers. Our chapter on why you should talk to a lawyer early explains why timing matters.

The Second District has shown a willingness to give injured patients their day in court; we wrote last year about its decision reviving a brain-injury malpractice case. Families in the Dayton area should know that hospitals and care facilities can be held accountable, and that the claims are serious and worth pursuing.
