The municipality of Itogon is the largest municipality of Benguet by land area. It has nine barangays, two of which are adjacent with each other and are considered the most economically depressed barangays in the municipality. These are barangay Dalupirip and Tinongdan. Except for little intermarriage, almost all residents are Ibaloys. They are generally poor especially now that mine tailings are collected in dams so gold panning which was the main source of their income previously is not done now a days. Both barangays have mountainous terrain. Tinongdan is located thirteen (13) kilometers southeast of PoblacionItogon and is 25 kilometers from Baguio City. Most sitios are located alongside of the big Agno River, south of Binga Dam. Some sitios are located at the top of the mountains specifically at the Benguet-Nueva Vizcaya provincial boundary, the Itogon-Bokod municipality boundary, and the Benguet-Pangasinan provincial boundary. Both barangays are traversed by a narrow and rough national road, the Bua-Itogon-Dalupirip road which is programmed to be linked to San Nicolas, Pangasinan. Transportation is very difficult that in times of emergency, patients cannot be brought immediately to the nearest hospital which is in Baguio City. This happens especially during rainy days because of landslides covering or cutting the roads. According to the RHU's, the most common causes of deaths were due to diarrheas, prenatal deaths and major wounds.
Considering all the facts and circumstances, a joint resolution of the barangay councils of barangay Tinongdan and Dalupirip was forwarded to the Municipality of Itogon, requesting for an emergency hospital on December 29, 1989. The resolution was favorably endorsed by the Sangguniang Bayan of Itogon under Mayor AlejoPacalso to the Ministry of Health in Metro Manila through the Honorable Assemblyman Andres A. Cosalan, IBP, Region I. The hospital is to be named "Bongbong Hospital" and is to be located in sitioBagueng in Barangay Tinongdan.
Assemblyman Cosalan introduced Parliamentary Bill no. 2282 which is, "An act establishing an emergency hospital in the sitio of Bagueng, Barangay Tinongdan, of the Municipality of Itogon, Province of Benguet, and authorizing the appropriation of funds therefore", in 1983. He proposed the name, "Mariano Fianza Emergency Hospital" after the late Mariano Fianza, a former Municipal President, who contributed to the economic, social and political growth of the municipality of Itogon. The hospital was to be under the direct supervision of the Director of the Medical Services, Ministry of Health.
With constant follow-up by our local officials, Republic Act no. 6875 was approved on March 8, 1990. This is "An act establishing a ten –bed capacity hospital in Tinongdan, Itogon, Benguet, to b known as Tinongdan Municipal Hospital and appropriating funds therefore."
The construction of the hospital started on May, 1992 and was completed on March, 1993. It was inaugurated and started to operate on July 1, 1994 and officially named ITOGON MUNICIPAL HOSPITAL.
