Comorbidities and their definition

Aspiration pneumoniaDocumented episodes of aspiration of saliva and or food requiring admission to hospital with changes on X-ray consistent with the diagnosis
BronchiectasisDisease where there is permanent enlargement of parts of the airways or lungs. Clubbed (usually) with history of recurrent chest infections or chronic lung disease confirmed by respiratory physician or bronchiectasis confirmed on CT scan of chest
DysphagiaDifficulties with swallowing associated with poor oromotor control (requires a modified diet, thickened fluids or gastrostomy feeds, pain on swallowing). May have choking on thin fluids or swallowing abnormalities confirmed on modified barium swallow
EpilepsyRecurrent seizures requiring anticonvulsant medication prn or daily
Gastro-oesophageal reflux (GOR)Obvious regurgitation on observation by clinician, has had cardioplasty or fundoplication due to GOR or diagnosis made by paediatric gastroenterologist. Reflux demonstrated on pH study or imaging study (eg, barium swallow, milk scan), abnormalities on endoscopy (eg, stricture or Barrett’s oesophagus)
Hydrocephalus shuntedVentriculoperitoneal or ventriculoatrial shunt in situ
Hydrocephalus unshuntedDiagnosis confirmed by neurosurgeon
Intellectual disabilityConfirmed by psychometric testing or on interview with school counsellor or psychologist
OesophagitisEndoscopy evidence of or biopsy proven oesophagitis where direct observation is ‘normal’
OsteoporosisLow impact fracture(s) or wedged vertebrae on lateral spine X-ray plus low bone mineral density on bone density scan/peripheral quantitative CT
Respiratory failureDocumented hypoxia and carbon dioxide retention/elevated bicarbonate in the appropriate clinical setting. Polysomnography may assist in this diagnosis. Non-invasive respiratory support may be considered
