About Kolan International Hospital, Istanbul

Kolan International Hospital has been operating since 1997 in the Sisli district of Istanbul - one of the most accessible locations in the city. The hospital is the flagship of the Kolan Health Group, which now operates 6 hospitals and 2 medical centers with a total capacity of 1,230 patients and over 3,000 staff members.

JCI accreditation was awarded in 2017. The hospital is one of only 49 JCI-accredited institutions in Turkey - out of the country's entire hospital system. Re-accreditation runs on a 3-year cycle, with each cycle requiring full reassessment of clinical standards, patient safety protocols, and treatment outcomes.

The Sisli campus covers 20,000 square metres with 174 beds, 6 operating rooms, 57 ICU beds (internal, surgical, coronary, cardiovascular surgery), a neonatal ICU with 31 incubators, and 40+ specialized departments. A specific institutional detail: Kolan International Hospital Sisli is the clinical base of the Faculty of Medicine of Okan University. Teaching hospital status means academic physicians on staff, research activity, and a professional environment oriented toward clinical precision.

The hospital is contracted to provide services to 28 government agencies including the Turkish Armed Forces and the Cyprus Consulate, and 46 non-government institutions. That procurement relationship reflects institutional confidence in Kolan's clinical standards.

Diagnostics include Siemens Biograph mCT, Siemens gamma cameras with E-soft computer support, computerised stress testing, and Lunar DPX bone tissue densitometry. The cancer program uses 3D radiotherapy combined with IMRT, chemotherapy, and immune-targeted therapy. Cardiac surgery includes a mini bypass approach that avoids cutting the breastbone or ribs - reducing recovery from 1.5+ months to under 15 days.
