Patrick Riordan, Archbishop of San Francisco, suggested that a hospital should be built as “a sanitarium for the sick and a home for the aged”.

Numerous sheltered porches, a solarium, and a garden pavilion enable the convalescent to enjoy the benefits of the outdoor air.

They comprise the surgical, medical, obstetrical, X-ray and electro-therapeutic departments, a clinical laboratory and pharmacy, and the isolation building for the care of contagious diseases.

Adjoining this is the delivery room with interior finish, furnishings, and equipment planned to provide every convenience for the physician and safeguard for the patient.

[1] The department of electro-therapeutics and radiography has been fully developed and equipped with costly paraphernalia and will prove of the utmost value in facilitating the diagnosis and treatment of various diseases and injuries.

Special diagnostic instruments, electrically illuminated, of the latest approved models, facilitate the diagnosis of the diseases of all accessible organs and tissues.

All highly contagious and infectious diseases—measles, scarlet fever, diphtheria, erysipelas, etc.--cannot be admitted or treated in the wards and rooms of the general hospital, and through lack of such a building many persons have been deprived of the facilities offered for the scientific conduct and efficient quarantine of such diseases.

The isolation building was erected through the beneficence of Mr. and Mrs. C. D. Blaney, and is conducted by the Sisters of Charity of St. Vincent de Paul.

The physicians of San Jose of all approved schools of medicine, patronized the sanitarium, thus assisting very materially toward its support by helping defer costs.

[3] As of 2020, O'Connor Hospital is a 358-bed acute care facility offering inpatient and outpatient medical, surgical and specialty programs to more than 1 million residents of San Jose.

[4] The Sisters of Charity of St. Vincent de Paul, at the invitation of the donors and suggestion of Archbishop Riordan, took possession/operation of the facility on March 19, 1889, and continued overseeing the operations of the hospital until 2002.

[5] Santa Clara County acquired the hospital, from Veritas over the objections of state Attorney General Xavier Becerra in a deal that closed on February 28, 2019.
