The Hospital Authority announced on September 28 that Kai Tak Hospital was scheduled to begin services in phases from October 5, with clinical services gradually transferring from Queen Elizabeth Hospital. The authority described the roughly 500,000-square-metre, 2,400-bed hospital, with five towers, as the largest public hospital in Hong Kong and the flagship of the Kowloon Central Cluster, serving a population of 1.8 million across Yau Tsim Mong, Kowloon City, Wong Tai Sin and Kwun Tong districts.

In the first phase, the Specialist Out-patient Clinic Block and Oncology Block were planned to open, with the Family Medicine Integrated Centre on the first floor providing around 250 clinic quotas per day initially. Appointments were to be accepted from the morning of October 4 via the HA Go app or telephone. Specialist out-patient services in medicine, surgery, neurosurgery and clinical oncology were to move from Queen Elizabeth Hospital in batches from late October, alongside allied health, radiology, pathology, pharmacy and other services rolling out during October.

Cluster Chief Executive Dr Eric Cheung said the out-patient block houses Hong Kong's largest pharmacy, with an automated dispensing system capable of a daily maximum of 3,200 prescriptions, while the oncology block includes the public system's first cyclotron and Gamma Knife. A second phase, including in-patient, surgical and accident and emergency services, was planned for 2028, with orthopaedics and traumatology, obstetrics and gynaecology, and paediatrics to follow.
