Outline of presentation • How NI39 is calculated • Latest trends in NI39 for England • How to calculate NI39 fro your own PCT/LA • NI 39 in Nottingham • How PCTs can reach their NI39 target- discussion • Ready Reckoner version 5
How alcohol admissions indicator is calculated • PSA 25.2, VSC26, NI39 • Developed in 2007 • Broader measure – includes conditions partially attributable to alcohol • Based on review of epidemiological literature by NWPHO • Produced set of conditions caused by alcohol and corresponding attributable fractions
The measure 13 wholly attributable conditions (attributable fraction of 1) Example: cancer of oesophagus Women aged 16-24, AF = 0.23 31 partially attributable conditions (attributable fraction less than 1)
Applied to NHS Information Centre’s data on Hospital Episodes • Admission episodes for residents; valid sex and age; classpat = 1,2,5 • Any mention of alcohol related diagnosis (not just primary diagnosis) Total = 7.56 • If more than one in episode, use largest AF – eg I10X = 0.34; G409 = 0.61 • Count of admissions; not patients (‘whole admission equivalent’) • To get rate, use ONS resident population estimates: http://www.statistics.gov.uk/statbase/Product.asp?vlnk=15106
Attributable fractions for the non-data minded! Ethanol poisoning 2 NI39 admissions = Epilepsy 2 X 4 X Hypertension Breast cancer 10 X 25 X
Improving access and understanding Pre-announced release dates • DH releases of data: • Q1 2009/10 • Final 2008/09 • Subsequent quarters about five months after end of quarter • NWPHO sub-analyses • 2007/08: December • 2008/09: January • Confidence intervals - scoping • HES ARA variable • Currently undergoing user acceptance testing • ARA tool • Feed admission level data in (from HES or SUS). Calculates attributable fractions and standardised rates. • Available on Alcohol Learning Centre: http://www.alcohollearningcentre.org.uk/Topics/Latest/Resource/?cid=5369 • Ready Reckoner • Assist PCTs to select interventions to reduce alcohol admissions. 4 high impact changes. • Also on ALC: http://www.alcohollearningcentre.org.uk/Topics/Browse/Commissioning/Data/?parent=5113&child=5109 • System Dynamics Model • Support to regions with trajectories More than just headline figures Better flagging of data quality issues
Latest data - England • National, regional and local figures for 2008/09 will be placed on the NWPHO within the next couple of weeks. • Information presented has not been fully validated. • Rate of admissions in 2008/09 was 1583 per 100,000 population, a 7.5% increase on 2007/08. This does not deliver the improvement of less than 5.5% that we were are aiming to achieve in our PSA, which was based on information about local actions. • It is an improvement on the projected increase of 8.0%. • This is higher than the rate suggested by the provisional figures currently on the web site.
Latest data - England • National, regional and local figures for Q1 of 2009/10 also being placed on the NWPHO site within the next fortnight. • Forecast outturn for 2009/10 based on Q1 data only is more pessimistic.
Latest data • There is some variation between regions and considerable variation between PCTs.
Conditions accounting for increase • Alcohol-specific conditions account for a quarter of the admissions, largely unchanged. Has grown by 81% since 2002/03, compared with 85% for all alcohol-related admissions. • Acute events account for 10% of the total, down slightly. • Accidents and injury, violence and cancers have each increased by less than average. • Hypertensive disease accounts for 35% of the total, up from 27% in 2002/03. Has grown by 145% since 2002/03. • Some due to better diagnosis and improvements in coding
Composition • Males account for over 60% • Increasing majority involve older patients • Some growth in elective at expense of “other emergency”, but majority still emergency via A&E Age Method of admission Sex
Change between provisional and final • Considerable change in South West and, to lesser extent, East Mids. • Former due to problems with data flow from North Bristol NHS Trust. • Six PCTs saw revisions of more than five per cent.
NI 39 in Nottingham The NI39 rate in Nottingham City is consistently significantly higher than either the East Midlands or England average
Understanding NI39 In 2007/08 the rate of hospital admissions for alcohol related harm was 1778 admissions per 100,000 population This is 4871 ‘NI39 admissions’ but 10,614 individuals.... and 15,611 actual admissions to hospital... Important to understand the difference between admissions and individuals
2007/08 – by age and sex • Highest contribution to individuals is from older women • However, the highest contribution to NI39 admissions is from middle aged men
Alcohol specific admissions by age and sex • Age and sex breakdown for alcohol specific admissions in Nottingham shows a very different pattern, highlighting males of most age groups
NI39 admissions by main cause – top 10 causes in Nottingham City • In Nottingham City in 2007/08 over 90% of NI39 admissions were due to the top 10 causes • The greatest overall contributor was hypertensive diseases (25%) followed by mental and behavioural disorders caused by alcohol (22%) and cardiac arrhythmias (15%) • There are differences in cause of admission by sex
Trends in cause – top 10 causes • Number of NI39 admissions increased by 16.7% between 2002/03 to 2007/08 (695.5 more admissions). The table below shows trends in the top 10 causes • almost half of this increase is due to an increase in mental and behavioural disorders, 30% due to hypertensive diseases and over 20% due to alcohol liver disease • Since 2002/03 NI 39admissions for chronic hepatitis and fibrosis of the liver have increased by 207% and alcoholic liver disease by 81%
Emergency versus elective admissions • 72% of NI39 admissions in Nottingham were emergency admissions, 25% elective • Mental and behavioural disorders are cause over a quarter of emergency NI39 admissions, hypertensive diseases 22% and cardiac arrhythmias 16%. • . Less than 600 individuals had mental and behavioural disorders compared to almost 3000 with hypertension
Readmissions • 2419 individuals admitted more than once resulting in 7416 readmissions • Cause of admission taken from the first incidence of admission • Hypertension accounts for 35% of readmissions and cardiac arrhythmias for 17.5% • More useful to look at emergency readmissions?
Emergency readmissions Hypertensive diseases and cardiac arrhythmias account for over 60% of emergency readmissions in Nottingham
Bed days The top 10 contributors to bed days in Nottingham City are shown below; hypertension (41%), cardiac arrhythmias (20%) and falls (12%) being highest
Zero bed days We also looked at zero bed days (admissions not passing through midnight). The top 10 are shown below. Hypertension was highest (30.8%) followed by psoriasis (11.4%)
How do we reduce our rising rates of alcohol related admissions? • Men contribute more to NI39, especially middle aged • Most admissions are emergencies (72%) • Main conditions that contribute: -Hypertensive disease (25%) and responsible for 20% of cause of increase in NI39 -Mental& behavioural (22%) and responsible for 46% of cause of increase in NI39 -Cardiac arrhythmias (15%) and responsible for 16% of cause of increase in NI39 -Epilepsy (8%) -Alcohol liver disease (7%) • Increases over 6 years most obvious in liver diseases
Possible interventions- what would you do? • Target the men (NB they don’t usually seek health care) • Most come as emergencies so key opportunity for Emergency Department (IBA) and alcohol liaison team • Hypertensive disease- but also asking GPs to improve detection. IBA may reduce incidence but will take time • Mental & behavioural (includes intoxication, harmful use, intoxication, withdrawal, DTs, psychosis, amnesia)- improved alcohol treatment services should help • Cardiac arrhythmias, epilepsy, liver disease- Alcohol workers in outpatient clinics, train medical & nursing staff in IBA • Epilepsy- specialist alcohol nurse in community neurology team • OTHERS e.g divert the admissions elsewhere?
