In 1965, the Government of Tamil Nadu upgraded this District Headquarters hospital to function as a teaching institution with 250 beds for clinical training.

Vedachalam Mudaliar, the then Chairman of Chengalpattu Municipality, donated[clarification needed] a vast area of land, which is in possession of this institution today.

The hospital, at its dawn, was functioning with the basic departments which included medicine, surgery, obstetrics and gynaecology, pediatrics, orthopedics, ophthalmology, otolaryngology, psychiatry and chest clinic.

As days went by, other departments started functioning one by one, making the hospital a tertiary care center with a multi specialty approach.

A new Tamil Nadu accident emergency intervention ward, catheterization lab and DEIC Unit have been opened.

Intensive Care Units for Surgery, Medicine, Paediatric, and Neonatology are present in the respective departments.

The Radiology department is equipped with CT-scan, MRI-Scan, Ultra-sound, Doppler, and digital X-ray facilities.

Admission is based strictly on merit and the reservation policies enforced by the Government of Tamil Nadu.
