Trends in Emergency Admissions in England 2004-2009

Why emergency admissions?

Emergency hospital admission is: • Undesirable • Expensive • Recorded in routine data

and • Thought to be increasing in number

Is it just emergency admissions?

Our analysis

The aims of the research were to: • Unpick the rise in admissions • Highlight characteristics of excess admissions • Explore variation at hospital and area level This work used the Hospital Episodes Statistics (HES) dataset to examine monthly emergency admissions over a five year period from April 2004 to March 2009.

Estimated cost of the rise in emergency admissions is equivalent to at least an additional £330 million in 2008/09 (compared to 2004/05 activity costed at 2008/09 payment levels). However, the actual value is likely to be higher due to inflation in the tariff over time and payment for non-tariff work.

How does the rise consume resources?

Is the pattern of stay length changing?

Is the increase related to age?

Has the case mix of emergency admissions changed?

(a) Age and sex standardised emergency admission ratio in 2004/05 (green, lowest, to red, highest)

(b) Absolute increase by 2008/09 (blue, dark = highest, light = lowest)

The evidence in summary...

Possible reason Comments Aging population Accounts for some of the increase, but not all Public expectations Increased demand for health services More treatable illness

No significant change in case mix, although vague symptoms increase disproportionately

Defensive medicine

The increase is due to short stay admissions; but could be many other explanations for these...

Central targets/Payment by Results

No evidence of 4-hour target driving systematic increase, and slightly pre-dates PbR

Change in other linked services

Could regional variation in the increase be a symptom of this?

Over reliance on A&E for urgent care

A&E attendance is increasing, as are admissions through A&E

Efficiency breeds inefficiency paradox?

Provider efficiency System inefficiency

Better and more efficient care

Reduction in length of stay

More beds available

Admission threshold reduced

Lower acuity cases using costly inpatient care

Less severe cases admitted
