The Corazon Locsin Montelibano Memorial Regional Hospital (CLMMRH), formerly called the Occidental Negros Provincial Hospital (ONPH), was founded on March 24, 1926 with a 25 bed capacity. Its first Chief of Hospital was Dr. Sixto Y. Orosa, Sr., who authored the landmark Philippine Provincial Hospital Act. In 1937, the bed capacity was increased to 100. When the war broke out in 1941, the hospital was closed to the public and the building was occupied by the Japanese Imperial Forces. In June 1942, the hospital reopened but was transferred to the old Maternity Hospital. After the war in February 1945, the hospital returned to its present site with its bed capacity increased to 150.
In 1962, ONPH was designated as training hospital for Western Visayas. On June 7, 1968, the name ONPH was changed to Corazon Locsin Montelibano Memorial Hospital in honor of the donor of the lot on which it stands. In 1977, the bed capacity was increased to 300. Four years later, by virtue of Batas Pambansa Bilang 118 dated January 21, 1981, its bed capacity was increased to 400. Significantly, the increase in bed capacity was not accompanied by a corresponding increase in plantilla position.
On July 3, 1984, it was reclassified into a regional hospital by virtue of Ministry of Health Administrative Order No. 95 and was renamed Western Visayas Regional Hospital. The name of the hospital further underwent another change per General Appropriation Act of 1985 to Corazon Locsin Montelibano memorial Regional Hospital.
The CLMMRH is a teaching-training tertiary hospital. All ten (10) departments are accredited, namely: Surgery, Internal Medicine, Obstetrics and Gynecology, Pediatrics, Anesthesia, ENT, Orthopedics, Ophthalmology, Pathology, and Radiology.
CLMMRH is the only tertiary government hospital in the province of Negros. It serves as the sole end referral government hospital for serious and complicated cases for the city of Bacolod and the entire province of Negros. It is located at Lacson-Burgos Streets, Bacolod City, Negros Occidental, Philippines.
