The Division of Pain Medicine in Department of Anaesthesiology, Queen Mary Hospital (QMH DA) is responsible for taking care of patients who are suffering from acute, chronic and cancer pain problems. Pain are referred from other medical specialists and health care professionals and seen at inpatient or outpatient clinics.

The QMH DA has been providing regular pain management services in QMH since 1990. This is the first formal pain management service in Hong Kong. The scope of services includes acute pain service (APS)—providing postoperative and other acute pain management; as well as chronic or cancer pain management—attending to all in-patient consultations from other specialties (with subsequent follow up care). The first out-patient clinic in pain management was jointly established by Department of Clinical Oncology and Department of Anaesthesiology in 1993. It serves patients with intractable cancer pain. The Division's own Pain Clinic was commenced in 1995 to look after out-patient referrals. In 1997, QMH DA was accredited by the Hong Kong College of Anaesthesiologists and became one of the first training centers of Diploma in Pain Management.
Scope of Clinical Services
Currently, the DA Division of Pain Medicine provides a comprehensive scope of pain management services in the QMH. These include APS, Chronic and Cancer pain management services (CPS).
Our APS focuses on pain management of patients after major operations (more than 3,200 patients were treated in 2010 alone). We also receive other pain consultations to manage patients suffering from thermal injury and traumatic painful conditions (e.g. rib fractures). Analgesic medications, patient-controlled analgesia (PCA), epidural analgesia and nerve/plexus blocks are commonly used. The patients are reviewed daily by anesthesiologists and a pain nurse. A twenty-four hour acute pain service is provided by the Department's Emergency Team. On top of this, a member of the Division of Pain Medicine is designated to provide tertiary consultation on 24 hour basis upon the Emergency Team's request.
The Division offers various protocols for acute pain management and patient monitoring. Because of these, high quality acute pain service could be carried out in different clinical areas e.g. the intensive care unit, high dependency unit and general wards. To ensure quality of care, implementation of APS protocols and patient monitoring are supervised by the Pain Nurse, who conducts a daily ward round with anaesthesiologists, as well as providing regular training to ward nurses.
Chronic Pain Service
Our CPS provides a comprehensive tertiary pain management service to both in-patients and out-patients, who are suffering from cancer pain or chronic (non-cancer) pain. We provide regular out-patient Pain Clinic Sessions, as well as Joint Outpatient Pain Clinic Sessions with the Department of Clinical Oncology (for cancer pain patients). CPS commences as soon as we received referrals from other medical specialties. After thorough patient assessment, we will formulate a pain management plan/schedule which is tailor-made to the patient. Treatment modalities ranging from simple analgesic regimens to more sophisticated therapies are provided. These include interventional pain procedures, cognitive behavioral therapy (the SMILE Program) and other multidisciplinary pain management involving other health care teams.
Multidisciplinary involvement is almost mandatory in modern pain medicine. The Division works in close collaboration with other medical specialists, clinical psychologists, physiotherapists, occupational therapists as well as medical social workers in the Hong Kong West Cluster. We play a coordinating role in this multidisciplinary team so as to provide holistic care to our patients. This is achieved through effective patient referral system as well as interdisciplinary case conferences.
Medical Records and Quality Assurance
All APS and CPS patients, have special medical records, both in hardcopies and electronic copies to ensure accurate documentation of diagnosis, treatment and progress. These records are managed by a designated clerical officer of the Division and strict protocols are in place to ensure patient confidentiality. Medical reports are issued upon request by the patient or other medical teams through proper hospital request channels. Moreover, patient care data are computerized for analysis to allow clinical audit and quality assurance activities.
The Division of Pain Medicine is committed to the training of pain specialists, anaesthetic vocational trainees, pain nurses and medical students. The Hong Kong College of Anaesthesiologists has accredited two training posts for the Diploma in Pain Management since 1997. 26 pain physicians have graduated so far. All of them excel at pain medicine, delivering specialist care to acute, chronic and cancer pain patients. The Division also welcomes overseas clinicians for training in pain medicine. Short term clinical attachment and fellowship appointments up to one year are provided.
In addition to clinical services, the Division of Pain Medicine also conducts research, in collaboration with the Department of Anaesthesiology, The University of Hong Kong. Numerous original articles, published in international peer-reviewed journals, and two medical textbooks and MD Thesis in pain medicine were harvested from this fertile ground of clinical research.
