Multidisciplinary & Patient-Centric Care
Group consultations form the core philosophy of AOI, enabling collective decision-making that draws upon the vast experience of multiple specialists. As part of SIMS Hospital’s comprehensive multi-specialty ecosystem, patients benefit from seamless access to advanced imaging, intensive care, renal support, rehabilitation programs, and allied specialties whenever required.
The Green Line Concept
AOI follows a unique Green Line Concept, where every patient—whether a new consultation, follow-up, emergency, or post-surgical review—receives structured counselling before and after treatment. A coordinated ecosystem of doctors, counsellors, and support teams ensures continuity of care, reduces patient anxiety, and enhances recovery. Post-surgical follow-ups are also supported through online consultations to minimise inconvenience and promote comfort.
