So, the numbers you're talking about are conservative esitmates.
They only include smokers. They don't include, for example, the children of smokers, who have many much more respiratory illness than other children.
The hospital admission costs only include this list, and only include them when these are the primary diagnosis of the admission episode.
Importantly, the cost used is the payment by results cost, not the actual cost to the treating trusts or GP surgeries.
> Smoking attributable admissions are defined as spells where the primary diagnosis of the admission episode is attributable to the following ICD-10 codes:
> malignant neoplasms: lip, oral cavity, pharynx (C00 to C14), oesophagus (C15), stomach (C16), pancreas (C25), larynx (C32), trachea, lung, bronchus (C33-C34), cervix uteri (C53), kidney and renal pelvis (C64 to C66, C68), urinary bladder (C67), acute myeloid leukaemia (C92), unspecified site (C80)
> cardiovascular diseases: ischaemic heart disease (I20 to I25), other heart disease (I00 to I09, I26 to I51), cerebrovascular disease (I60 to I69), atherosclerosis (I70), aortic aneurysm (I71), other arterial disease (I72 to I78)
> respiratory diseases: pneumonia, influenza (J10 to J18), bronchitis, emphysema (J40 to J43), chronic airway obstruction (J44)
> diseases of the digestive system: stomach ulcer, duodenal ulcer (K25 to K27), Crohn’s disease (K50), periodontal disease (K05)
> other diseases: age related cataract (H25), hip fracture (S72.0 to S72.2), spontaneous abortion (O03)
