The hospital for chronic patients in Sokolniki was built between 1885 and 1887 thanks to donations from well-known philanthropists, brothers Pyotr, Alexander, and Vasily Bahrušins, in whose honor it was named.

The Bahrušins, representatives of the second generation of a famous merchant dynasty, owned leather and cloth factories and were co-founders of the "Partnership of Alexey Bahrušin's Sons." They also became renowned as generous benefactors. One of their significant contributions was the establishment of a hospital for chronic patients in Sokolniki. The city allocated a large plot in the northern part of Sokolnichy Field, which at that time was not yet fully built up. The hospital was constructed from 1885 to 1887 according to the design of architect Boris Freidenberg with the participation of Mikhail Chichagov. The Bahrušins allocated 450 thousand rubles for the construction and maintenance of the hospital, which was designed for 200 beds. It accepted patients from all social classes, primarily from low-income groups; patients treated for free were called "Bahrušin brothers' pensioners."

The hospital complex occupied an entire block, and two new streets laid along its borders were named Bolshaya and Malaya Bahrušinskaya Streets (now B. and M. Ostromovskie Streets). The hospital buildings were located along Stromynka Street, set back slightly from the red line, with a garden behind them. The buildings were executed in the neo-Russian style, with the main building being more ornate, its facade adorned with elegant window frames, a cornice, and a grand entrance staircase in the center. The building was topped with three church domes of the chapel dedicated to the Icon of the Mother of God "Joy of All Who Sorrow," the main church of the hospital. The second hospital church, dedicated to St. Panteleimon, also in the neo-Russian style, was located closer to M. Bahrušinskaya Street. Under the chapel, a family crypt for the Bahrušins was arranged, where all three brothers and their wives were later buried.

Over time, the hospital expanded, and new buildings were constructed. In 1892, a hospice for incurable patients was built, in 1902, a maternity hospital with an orphanage (designed by architect Illarion Ivanov-Shits on funds from the Moscow City Administration), and a few years later, an outpatient clinic and a building for tuberculosis patients.

After the Bolsheviks came to power, the hospital was renamed in honor of Dr. A.A. Ostromov, who had worked there for a long time. Bahrušin Streets became Ostromovskie. Both hospital churches were closed in the early 1920s, the chapel dedicated to the Icon of the Mother of God "Joy of All Who Sorrow" was soon demolished, and the central part of the main building was raised by a third floor. The decapitated church of St. Panteleimon was used as a morgue for a long time until its demolition in 1971.

The family crypt of the Bahrušins was planned to be liquidated along with the church, but due to a lack of funds for reburial, relatives decided to seal the crypt to preserve the graves from desecration. It is highly likely that the remains of the Bahrušins are still in this crypt.
