The female patient was sent to the Accident and Emergency Department of the hospital by ambulance at about 5.30pm on December 4 for chest pain and abdominal pain. The doctor arranged an electrocardiogram and chest X-ray examination for the patient and prescribed anti-angina drugs to alleviate her chest pain.

The patient was then transferred to the medical ward at around 8pm for further treatment, and her vital signs were noted to be normal.

At around 11.50pm, an on-call doctor reviewed the patient's clinical condition, prescribed antacid for her abdominal pain, and continued the monitoring. As the patient's discomfort did not improve and she vomited, the doctor prescribed intravenous antiemetic treatment to stop her from throwing up.

The patient was conscious and did not report any discomfort when assessed by ward staff at around 4am on December 5.

Ward staff reviewed the patient's vital signs again at around 6am and found her unconscious and in cardiac arrest. Resuscitation was performed immediately, and resuscitation drugs were given. The patient eventually passed away at about 7am.

The hospital said they are concerned about the case, and the clinical team spoke to the patient's family on Thursday. The hospital then extended its condolence and apologized to the family for not having connected a cardiac monitoring device to the patient and not arranging a CT examination.

The hospital then added the case has been referred to the coroner and reported to the Hospital Authority Head Office and that they will continue to communicate with and render support to the family.
