 - acute conditions (e.g. ear, nose and throat infections, perforated/bleeding ulcer, pelvic inflammatory disease) (excluding dehydration and gastroenteritis).
 - chronic conditions (e.g. diabetes (principal diagnoses only), asthma, angina, hypertension, congestive heart failure and chronic obstructive pulmonary disease).
