  1. * NS-SEC, National Statistics Socio-economic Classification (UK) [25]
  2. † Scores for the Acute Physiology, Age, and Chronic Health Evaluation (APACHE II) [26] range from 0 to 71; higher scores indicate more severe illness
  3. ‡ In the Therapeutic Intervention Scoring System [27] points are added for each new ICU activity
  4. ** Categories of post-hospital destination were 1. Home 2. Transfer to other hospital 3. Care or rehab centre 4. Died in hospital 5. Readmission since discharge home 6. Still in hospital at three months (not yet discharged). Numbers in each category are not reported here due to lack of space
  5. †† Primary body system had 11 categories: respiratory, cardiovascular, gastro-intestinal, neurological, trauma, poisoning, genito-urinary, endocrine, haematological, musculo-skeletal and dermatological. Numbers in each category are not reported here due to lack of space.
