End-of-life care research in Hong Kong: A systematic review of peer-reviewed publications.

OBJECTIVE

This systematic review aimed to examine end-of-life (EoL) care research undertaken in an Eastern cultural context--Hong Kong--with the hope of better informing EoL care professionals and policy makers and providing lessons for other countries or areas that share similar EoL care challenges.

METHOD

Eight databases were searched from their respective inception through to August of 2014. All of the resulting studies conducted in Hong Kong and relevant to EoL care or palliative care were examined. The included studies were assessed with respect to study design, care settings, participants, research themes, and major findings.

RESULTS

Some 107 publications published between 1991 and 2014 were identified. These studies were undertaken at a range of places by different professionals. Of the total, 44 were led by physicians, 36 by nurses, 17 by social workers, and 10 by other professionals. Participants included both inpatients and outpatients with different illnesses, nursing home residents, older community-dwelling adults, deceased individuals, care staff, and informal caregivers. A total of 13 research themes were identified: (1) attitudes to or perceptions of death and dying; (2) utilization of healthcare services, (3) physical symptoms or medical problems; (4) death anxiety or mental health issues; (5) quality of life; (6) advance directives or advance care planning; (7) supportive care needs, (8) decision making; (9) spirituality; (10) cost-effectiveness or utility studies; (11) care professionals' education and training; (12) informal caregivers' perceptions and experience; and (13) scale development or validation.

SIGNIFICANCE OF RESULTS

While there has been a wide and diverse range of research activities in Hong Kong, EoL care services at primary care settings should be strengthened. Some priority areas for further research are recommended.
