An investigation has been launched after a patient killed themselves on a hospital ward.

Documents have revealed a full investigation has been launched at Springfield Hospital, in Tooting, following an ‘inpatient suicide’ on Ward 3.

The South West London and St George’s Mental Health Trust said they provided immediate support to the person’s family, patients on the ward and staff.

But the trust was unable to provide us with a date of the incident.

The document referred to the death as a ‘suicide’ however the case has not yet been referred to a coroner’s court and a hospital spokesman confirmed the word should not have been used.

Ward 3 is an in-patient ward with 20 beds and treats people with everything from schizophrenia, to self-harm and eating disorders.

All in-patients have their own single bedrooms with ensuite facilities with furniture, fixtures and fittings.

Director of nursing and quality standards for the trust, Andrew Dean, said: "We are deeply saddened by this tragic death and have extended our support to the deceased’s family as well as patients and staff on the ward.

"The safety of service users is our trust’s top priority and we have initiated a root cause analysis investigation, led by an independent chair, which is conducting a thorough examination.

"It would be inappropriate to say anything further until that investigation is complete."

The trust provides community and hospital psychiatric services for Wandsworth, Kingston, Richmond, Sutton and Merton.
