Emergency hospital admissions for Myocardial Infarction (heart attack) (count) (3257) Metric type
- Help text
- Count of emergency hospital admissions (myocardial infarction), all ages, persons.
Methodology:
England age specific admission rates were calculated from all admission episodes with valid MSOA and age coding.
Unadjusted expected admissions within each MSOA are calculated by applying age-specific admission rates for England in the latest 5 years to each MSOA's population.
These have been adjusted to compensate for the effect of missing age codes within the National data; this methodology assumes that the age distribution within the missing data is
the same as that at the National level.
MSOA admissions contain all admissions for that area, irrespective of age coding (i.e.
they include non valid age coding).
Standardised Admission Ratio (SMR) = MSOA Observed / Adjusted MSOA Expected admissions * 100.
England Expected value is the sum of all the Adjusted MSOA Expected admissions.
Numerator = Observed Myocardial Infarction admissions; defined by a primary diagnosis (ICD10) code of I21*or I22*; Emergency admissions with an admission method of 21 - 28 and
patient classification 'ordinary' (1 or 2), which are completed during the time period stated above (episode status = 3, episorder = 1).
A patients area of residence is defined by the Middle Super Output Area Code (MSOA) as supplied with the HES dataset.
Denominator = Expected admissions during the time period (Adjusted).
Adjusted MSOA Expected values = (Unadjusted MSOA Expected values) X (Total England Observed Admissions) / (Total England Observed Admissions with valid start age).
