2. SPARRA
• What does it do?
– Risk factors / Patient Examples
• History of Development
• How is it being used?
– The Long Term Conditions Collaborative
• Current & Future Development
3. SPARRA
Scottish
Patients
At
Risk of
Readmission and
Admission
SPARRA is an algorithm for predicting a patient’s risk
of emergency inpatient admission in a particular year
4. SPARRA – Current Risk factors
Age
Gender
Deprivation Level of Residence
Number of previous emergency admissions
Time since last emergency admission Inpatient/Day
Case history in 3
Total bed days accumulated in the 3 years
years prior to the
Principal diagnosis (last emergency admission) risk year
Co-morbidity – number of diagnostic groups
Number of Elective admissions
Emergency Admission rate (standardised) of patient’s GP practice
Historic Period
2007 2008 2009 2010
Predictor Outcome
variables year
5. Example: individual with very high
predicted probability of admission
• Predicted probability of admission 86%
• Male aged 67
• Less than one month since most recent admission
• 6 previous emergency admissions
• Glasgow – most deprived decile
• Most recent admission diagnosis: COPD
6. Example: individual with very low
probability of admission
• Probability of admission 8%
• Male aged 67
• 2 years since most recent admission
• 1 previous emergency admissions
• Lothian – 2nd least deprived decile
• Most recent admission diagnosis: Injury
7. Development History
2006
• Initial Focus on those aged 65+
• Base-data
– Sources from National Inpatient/Day Case Data (SMR01)
– Patients with >=1 emergency admission 2001-2003 (200K+)
– Risk of admission 2004 – outcome was known
– Deaths before end of 2003 excluded
• Algorithm developed using multiple logistic regression
2008
Extension to those under 65
• Modelling work repeated on an ‘all ages’ cohort (700K+)
• Identifies 2 x high risk (50%) patients
• Adopted within the SPARRA service January 2009
SPARRA MH – risk of psychiatric inpatient admission
8. SPARRA the ISD service
• Risk Scores generated quarterly for all relevant patients
– >700K (previously 200K)
• Data relating to their ‘at risk’ population distributed to Health
Boards, CHPs & practices
– Chosen risk thresholds (often >50%)
– Patient-level data for medium to high risk patients

10. SPARRA – Current Development Strategy
• Priority is more comprehensive case-finding tool
“Enhance SPARRA by expanding the cohort for whom a risk can be
estimated beyond those with a recent history of hospital admission”
Scottish Government – National LTC Action Plan
• Need to look at other data sources that
–will extend the cohort
–contain risk factors that will improve discriminatory power
– are likely to be available in most localities

11. SPARRA – Current Projects
• Using external data sources e.g.
– Data held by Primary Care Clinical Informatics Unit, Aberdeen
University on 40 practices and linked with national hospital
admission data
• Maximising/simplifying use of hospital admission data
– Admissions related to alcohol or drug misuse
– Admissions related to falls
– LTCs
• Streamlining our data generation/distribution process
– Making using of ISD’s warehousing developments
– Monthly updates
• SPARRA MH
– Evaluating long-term role
– Overlaps with ‘acute’ SPARRA cohort
12. Long Term Conditions Collaborative
‘Delivering sustainable improvements in
person centred services for people with
long term conditions’

13. Policy Context
• Long Term Conditions Action Plan – June 2009
– Person Centred Care & Mutuality
– 7 Change Actions
