When a person or organization has a duty to watch, guide, or protect someone and does not provide the level of oversight that a reasonable situation requires, that can be a failure to supervise.

In everyday terms, it means not paying proper attention when supervision could prevent harm. That can happen in many settings: a school not monitoring children, an employer ignoring unsafe worker behavior, or a care facility leaving a confused resident alone near a fall risk. In a nursing home or assisted living setting, failure to supervise often comes up when staff do not check on a resident often enough, do not respond to wandering, miss medication-related changes, or leave someone without help during transfers, meals, bathing, or toileting. The result may be falls, dehydration, pressure injuries, choking, elopement, or assaults by others.

For an injury claim, the key question is usually whether the facility or caregiver knew, or should have known, that closer supervision was needed. Records about care plans, staffing levels, prior incidents, and doctor's orders can help show negligence or elder neglect. In Hawaii, claims may also connect to the state's Adult Protective Services Act, Haw. Rev. Stat. Chapter 346, Part X (2024), when a vulnerable adult is harmed by neglect. Proof that better monitoring likely would have prevented the injury can strengthen a case for damages.
