BackgroundBackground� National audit based on agreed standards and
evidence-based guidelines is expected to improve clinical practice, and thereby significantly reduce the mortality and morbidity associated with FH.
� Audit standards and indicators were developed from the NICE Clinical Guideline for the Identification and Management of FH (CG71, 2008).
� A 14 Site pilot was run in 2009 to test the methodology. This resulted in the notes of 226 adults and 22 children with FH being examined.
� On the basis of this experience the full national audit was developed.122 sites participated in the 2010 national audit. This resulted in the notes of 2324 adults and 147 children with FH being examined.
Issue date: August 2008

Organisational Audit – Key Results - 5
� On average sites reported 1 consultant PA/wk for lipid management, of
which 35% is spent on FH patients.
� 86% of sites had no lipid specialist Nurse
Number Consultant PAs Number Nurses
Many sites are a single Consultant and no Nurse
Organisational Audit – Key Results - 6
� Median number of New FH patients seen last year was 20 (IQR 7-50)
� Median number FH patients in follow up was 50 (IQR 20-140)
Number New Adult Patients Number Adult Patients in Follow-up
Total = 4276 Total = 11065
Many small and some large sitesOverall ~15,000 FH patients currently being seen
� Organisational aspects of the care pathway for FH are still being developed.
� Current resources are inadequate to cope with the identification of thepredicted FH relatives of affected cases UK wide. This includes accessto trained staff (86% of sites had no lipid specialist nurses), IT provision and pedigree drawing.
Organisational Audit - Key Findings
and pedigree drawing.
� There is a major lack of family “cascade” testing, whether carried out on the basis of lipid levels or, more effectively, by a DNA diagnosis.
� While there is good access to DNA diagnosis and funding for DNA testing in the Devolved Countries, access and funding in England is poor.
� Commissioning arrangements need urgently to be reviewed for key elements of the services for FH patients, both at national and local levels.
� Several aspects of the care pathways for FH patients need to be implemented, including shared care arrangements between hospital andprimary care and better links between with several other specialties, including paediatrics.
�
Organisational Audit Key Recommendations
� Additional resources will be needed to cope with the care of new FH patients identified by cascade testing. Training to address the shortage ofstaff with key skills will be required.
� Systems need to be developed and implemented to carry out comprehensive “cascade” testing. This will require trained health professionals with the appropriate skills to follow up the families of indexpatients, improved IT resources, including an FH patient database, and pedigree drawing.

Since only 3rd visit some further falls may occur
� While good management of FH patients is occurring in both small andlarge sites, there is some evidence that small sites adhere less fully
Key Findings
� The clinical management in lipid clinics is of a good standard for individual patients who have been diagnosed with FH.
� Lipid lowering therapy is not yet optimal (8% still LDL-C > 5.0mmol/l)
Adults
large sites, there is some evidence that small sites adhere less fully to key aspects of the guideline. (annual review, pedigree data and initiation of cascade testing).
� There is a shortfall in child-focused services throughout the country,with only 26% of sites offering paediatric FH services.
� Where such services were audited they are of a good standard.
Children
� The establishment of multidisciplinary teams should be encouraged sincethey appear to achieve better implementation of the guidelines and management of FH patients.
� Resources are needed for DNA diagnosis and Clinical Genetics input.
� Based on published data, cascade testing alone will find less than 50% ofthe predicted 100,000 unidentified FH patients in the UK, and other methods for finding FH probands will need to be explored.
Key Recommendations
methods for finding FH probands will need to be explored.
National Organisations:
� Given that FH families are geographically dispersed, cascade testing maybe facilitated by a specifically funded UK FH Register to which all FH cases would be notified
� It is recommended that a second UK wide audit of services should be commissioned to start in 2012.
