Emirates-based day surgery group Medstar is investing $100m to open new facilities in Dubai, Sharjah, Ras al-Khaimah and Al-Ain. It opened its first clinic in Dubai in late 2015, and is working with insurers to cut costs by 25-30% compared to hospital groups, founding doctor Sajid Burud says. Day surgery clinics are set to proliferate, as the UAE implements Mandatory Health Insurance (MHI).
