Emergency hospital admissions for all causes (standardised admission ratio) (3175) Metric type
- Help text
- Emergency hospital admissions (all causes), indirectly age standardised ratio, 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 admissions; 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).
Confidence Limits:
Confidence limits provide an indication of the reliability of a result.
The 95% confidence intervals provide a range within which there is 95% chance of the true result lying.
Confidence intervals were calculated using Byar's Method as described in APHO Technical Briefing 3: Commonly used public health measures and their confidence intervals.
