Subsequent to the rising interest in complementary therapies, a survey was conducted to determine the extent of integration of complementary therapies in critical care units in the North and South Thames Regional Health Authorities in the Greater London area. In total, 45 critical care units were surveyed at random. The results of the survey indicated Neonatal Intensive Care Units showed the greatest interest and provision (75%) of complementary therapies. This was primarily in the application of baby massage. In contrast, only 10% of Coronary Care Units surveyed provided complementary therapies. Results further indicated that of 51.1% of critical care units which claimed to provide complementary therapies, only 7% provided interventions on a routine, systematic basis.
