Please give additional activity details (i.e., reach, impact, duration, return on investment) Cochrane Hong Kong works in collaboration with Nurse Consultants (Gerontology) and Nursing Services Department of the Hospital Authority to advance evidence-based practices and policies. A landmark clinical trial evaluating the diagnostic accuracy of capnography for nasogastric tube placement is under way with the aim of generating robust evidence to support clinical decision-making and ensure the safe and effective placement of the nasogastric tube. Our research has successfully recruited participants from general medical and geriatric wards of acute hospitals, subacute/rehabilitation/infirmary wards of subacute/convalescent/extended care hospitals, intensive care units, and are awaiting the completion of data collection in emergency departments.
