​The Health Management Unit (HMU) was formed in 2011 at Changi General Hospital to empower patients with the knowledge and skills to manage their chronic conditions confidently at home.

Patients who are referred for the telecare service receive regular phone support by experienced and trained nurses, also known as telecarers. The telecarers support patients with diabetes, chronic obstructive pulmonary disease (COPD), heart failure, hip fracture and acute myocardial infarct.

Services include:

Tele-monitoring: Parameters such as blood glucose, pulse rate, blood pressure and weight of patients are captured and monitored by telecarers.
Tele-education: ​Patients are educated on how to recognise and manage symptoms related to their condition.   For example, patients with diabetes are taught how to recognise symptoms of hypoglycaemia (very low blood sugar) and what to do when they encounter such episodes
Care coordination: ​Telecarers work with other healthcare partners to coordinate patients' care, including but not limited to polyclinics and GPs, case managers, psychologists, allied health professionals and intermediate and long term care (ILTC) providers.

Telecarers also use a Patient Relations Management IT system which alerts them whenever patients they are managing visit the A&E, are admitted to the hospital, miss their follow-up appointments, or have any abnormal laboratory results related to their chronic condition. This enables early intervention and follow-up care.
