About This Facility

Memorial Sisli Hospital is a large private hospital in the Sisli district of Istanbul, established in 2000 as part of the Memorial Healthcare Group, one of Turkey’s most prominent private hospital chains. The facility employs approximately 800 staff across medical, surgical, nursing, and administrative departments and holds both JCI accreditation and a Turkish Ministry of Health licence.

The hospital’s oncology department offers a full range of chemotherapy and targeted therapy protocols, supported by a multidisciplinary tumour board, molecular diagnostics laboratory, and a dedicated chemotherapy day unit with individual infusion bays. The cardiac surgery and orthopaedic departments also serve international patients, with coronary artery bypass grafting and total knee replacement among the most commonly performed procedures.

International patient services are managed through a dedicated department that provides multilingual coordination in English, Arabic, Russian, and German. The hospital arranges airport transfers, hotel accommodation, and medical visa documentation. Its location in Sisli places it centrally within Istanbul, with good transport links to both airports.

The facility is equipped with modern imaging suites including PET-CT and MRI, robotic-assisted surgical systems, and catheterisation laboratories. The hospital’s 24-hour emergency department and intensive care unit provide comprehensive backup for post-operative and oncological emergencies. Clinical governance at Memorial Sisli follows a structured programme of morbidity and mortality reviews, peer audit, and mandatory incident reporting. The hospital publishes patient satisfaction survey results internally and uses them to drive service improvements across its international patient programme. Pharmacy services include access to a comprehensive formulary of oncology drugs, including branded biologics and biosimilars, dispensed under pharmacist-supervised protocols.

Memorial Sisli Hospital — Frequently Asked Questions

How can I verify Memorial Sisli Hospital's JCI accreditation?

JCI (Joint Commission International) accreditation for Memorial Sisli Hospital has been confirmed independently by this registry via the JCI public directory of accredited organisations at jointcommissioninternational.org. Patients can verify this directly by searching the directory by country and hospital name. The hospital also holds a Turkish Ministry of Health operating licence, confirmed via shgm.saglik.gov.tr. Both accreditations were last verified by this registry on 18 May 2024. The corporate registration (number 0634-0007-3310, registered 14 February 2000) can be confirmed as active through the Turkish Trade Registry at ticaretsicil.gov.tr. JCI accreditation confirms that facility-wide systems and processes met the relevant standards at the time of assessment.

How do I verify the credentials of a specific surgeon at Memorial Sisli Hospital?

Individual surgeon registration in Turkey is recorded by the Turkish Medical Association (Türk Tabipleri Birliği) at ttb.org.tr. Patients should request the full name and TTB registration number of the surgeon who will perform their procedure and search the register directly. Memorial Sisli Hospital's JCI accreditation requires that the hospital maintains a documented credentialling and privileging process for all medical staff, meaning the hospital should be able to supply verification documentation upon request. For specialist procedures such as coronary artery bypass grafting, knee replacement, or oncology treatment, confirming the surgeon's board-recognised specialisation is particularly important.

What anaesthesia qualifications and protocols apply to surgery at Memorial Sisli Hospital?

As a JCI-accredited multi-specialty hospital with operating theatres conducting cardiac surgery, orthopaedic procedures, and other general surgical cases, Memorial Sisli Hospital maintains a specialist anaesthesiology department. JCI standards require that anaesthesiologists are appropriately qualified and that documented pre-anaesthetic assessment, intra-operative monitoring, and post-anaesthetic care protocols are in place. Patients scheduled for procedures requiring general anaesthesia should expect a formal pre-operative anaesthetic assessment, which typically includes review of medical history, current medications, allergies, and airway examination. Patients with significant comorbidities — including cardiovascular, respiratory, or renal conditions — should ensure all relevant records are available in advance.

How does Memorial Sisli Hospital handle complications during or after surgery?

Memorial Sisli Hospital maintains a 24-hour emergency department and intensive care unit, providing on-site capacity to manage surgical complications including post-operative haemorrhage, cardiac events, and infection. The hospital's JCI accreditation requires documented protocols for managing adverse events and escalation pathways. Patients who return home and subsequently develop a complication should contact the hospital's international patient department and simultaneously seek assessment from a local clinician. For conditions such as deep vein thrombosis, pulmonary embolism, or wound infection — which can present days to weeks after discharge — early local medical assessment is important and should not be delayed while awaiting a remote response from the hospital.

What is the revision or re-treatment policy for surgical and oncological procedures?

Memorial Sisli Hospital does not publish procedure pricing or treatment terms publicly; individual quotations are provided following consultation. Patients should ask the hospital's international patient department specifically about the re-treatment policy for their procedure — for example, what the process is if a joint replacement requires early revision due to implant failure, or if a chemotherapy protocol needs to be modified due to toxicity. The terms under which additional treatment is provided, and at what cost, should be confirmed in writing before booking. For oncological cases, ongoing treatment planning is typically managed dynamically by the multidisciplinary tumour board and is inherently less predefined than elective surgical procedures.

Does Memorial Sisli Hospital publish its prices?

Memorial Sisli Hospital does not publish procedure pricing on its website. Fees are provided following an individual consultation, which is available remotely for international patients. When requesting a quote, patients should ask for a fully itemised breakdown covering the surgical fee, anaesthesiologist fee, operating theatre costs, inpatient ward charges per night, laboratory and imaging fees, and the international patient coordination fee if applicable. For oncological treatment, the cost of chemotherapy agents — which varies significantly by drug and protocol — should be itemised separately. Currency and payment terms should also be confirmed, as large medical invoices may have specific payment schedule requirements.

What deposit and refund terms apply for international patients?

Memorial Sisli Hospital's deposit and refund policy is not published publicly. Before paying any advance fee, patients should request the full terms in writing, covering the amount required to confirm a surgical date, the cancellation deadline for a refund, and the procedure that applies if surgery cannot proceed due to a clinical finding identified during pre-operative assessment. For international patients who have arranged travel specifically for a planned procedure, travel and medical procedure cancellation insurance — available from specialist medical travel insurers — is advisable. Cancellation policies for oncological treatment, where treatment scheduling may be clinically time-sensitive, may differ from those for elective surgical procedures.

How does the hospital coordinate care for international patients before and after treatment?

Memorial Sisli Hospital's international patient department provides multilingual coordination in English, Arabic, Russian, and German. Services include pre-operative remote consultation, airport transfer arrangement, hotel accommodation coordination, medical visa documentation assistance, and post-discharge follow-up. The hospital's location in Sisli, central Istanbul, is accessible from both Istanbul Airport and Sabiha Gökçen Airport. After discharge, follow-up consultations can be conducted remotely for international patients. Patients should establish before departure the specific post-discharge follow-up schedule, how clinical records will be transmitted to their home-country clinicians, and the procedure for obtaining prescription medications following a course of treatment.

What language support is available at Memorial Sisli Hospital?

The hospital's international patient department operates in English, Arabic, Russian, and German, reflecting the hospital's principal patient markets from the Middle East and Europe. Patients communicating in other languages should confirm interpreter availability before booking. For clinical consultations involving surgical consent, chemotherapy protocol discussion, or orthopaedic assessment, communication directly between the patient and the treating clinician — or via a qualified medical interpreter rather than an administrative coordinator — is preferable. The hospital's 6,200 Google reviews averaging 4.4 suggest a high volume of international patients with varied language backgrounds.

What happens if my planned surgery is cancelled on the day due to a pre-operative finding?

Day-of-surgery cancellations at Memorial Sisli Hospital may occur if pre-operative assessment identifies a contraindication — such as an abnormal blood coagulation result before cardiac surgery, elevated infection markers, or an anaesthetic risk requiring further cardiology or respiratory investigation. In such cases, the hospital's JCI-accredited clinical governance processes require that the clinical decision is documented and the patient is advised of the reasons. Patients should ask the hospital's international patient department in advance what the policy is for covering or crediting fees paid if surgery is postponed due to a clinical finding on the day, and whether assistance is provided with rebooking travel. Specialist medical travel insurance policies that cover clinician-initiated postponements are available.
