Decedents Found in Bathtubs.

We investigated deaths in bathtubs for criteria to assist in death certification. We reviewed 252 deaths in which the person was found dead in a bathtub/shower at home. We extracted cause, manner, age, clad or unclad, water in the bathtub, water running, and face submersion. Of the 252 deaths, heart disease was the leading cause of death (129), followed by intoxication (47), trauma (22), drowning (28), and other diseases (26). The manners of death were 155 natural, 64 accident, 30 suicide, and 3 homicides. All drowning fatalities involved the decedent having their face submerged. Intoxication and natural deaths had submersion of the face in 15% and 12% of deaths, respectively. For nondrowning causes of death, the majority were without face submersion. For natural deaths, the predominant circumstance was the individual discovered unclad with water in the bathtub and the face not submerged. Conversely, for suicides, the majority were found clad without water. A comprehensive investigation incorporating a scene examination, gathering of the medical and psychosocial history, and typically an autopsy is needed to certify the cause and manner of death. Face submersion alone is not diagnostic of a drowning and must be interpreted with the medical history and autopsy findings.
