There is little consistency of practice in some areas such as pregnancy testing, DVT prophylaxis or partner visiting, whereas in others, such as involving young people in healthcare decisions where possible, practice is consistently good. Further research should focus on the young people's experience of critical care to refine healthcare policy. What is Known: • Adolescents have distinct health and psychosocial needs that are often poorly catered for in contemporary healthcare settings, including critical care. • As adolescents are infrequent patients for any intensive care unit, there is a poor research base and essentially no guidance, regarding optimal care. What is New: • We developed a mnemonic with adolescents and ICU staff to improve healthcare delivery to young people in critical care, the 6Ps: privacy, permission, DVT prophylaxis, personal life, puberty and practical issues. • Delivery of the adolescents' critical care varies greatly both between and within countries; the 6Ps offers a method of standardising and improving this across different countries.
