Annual inspection and examination

Aggressive intervention to reduce morbidity

Primary and secondary care should work together to identify a package of care for at risk feet

N.I.C.E.

‘foot ulceration and lower limb amputation can be reduced if people who have sensory neuropathy affecting their feet are identified and offered regular podiatry and protective footwear if required’

Conclusion from footwear Conclusion from footwear follow-up studyfollow-up study

Prescribed footwear is effective when worn, inspection is a vital part of follow up although this is written into guide lines it is not usually adhered to.

The importance of footwear review The importance of footwear review needs more emphasis at all levels of needs more emphasis at all levels of carecare

That’s ok but is it cost effective?

Cost Savings by OrthoticsCost Savings by Orthotics

Allied Health Professions input to the Diabetes pathway

• The cost on the NHS to heal one ulcer is £3k to £7.5k. Should this progress to amputation the cost is estimated to escalate to £65k. This is much more than the cost of preventative orthoses.

• For every £1 spent in orthotics the NHS saves £4.

HOME? NOT SO SWEET HOME

Lomax G McLaughlin C Jones G R Kenwright C Blackburn Royal Infirmary

HOME? NOT SO SWEET HOME“THE GREATESTNUMBER OF STEPS PER DAYARE TAKEN INTHE PATIENTS OWN HOME.”

David Armstrong et al. (American Podiatric Medicine 2001)

HOME? NOT SO SWEET HOMEPRESCRIBED INSOLES AND FOOTWEAR CAN PREVENT FOOT PATHOLOGY

(TOVEY F.I. 1987)


Footwear is most effective when worn for a minimum of 60% of the day. (Chanteleau, E. Haage, P.)

Most effective when worn for 100% of the ambulatory time.


AIM OF STUDY

To assess what proportion of patients who had been prescribed Diabetic footwear were wearing at home.


How could we do this study?

• Ask patients at clinics?• A telephone survey?• Send patient questionnaires?• Knock on patient doors and ask and look?• Data collection by Community Podiatrists visiting

patients homes on Domiciliary visits. “The sneak approach”

HOME? NOT SO SWEET HOMERESULTS

Question No shoes Own shoes Own slippers

Prescribed

shoes

1. What is patient wearing on entry to house?

19% 8% 52% 21%

2. What does patient apply after treatment?

15% 8% 56% 21%


CONCLUSION

• 75% of patients visited do not wear prescribed shoes at home.

• All health care professionals need to be aware of this.

Care of People with Charcot Osteoarthropathy (NICE 01/04)

“People with suspected or diagnosed Charcot osteoarthropathy should be referred immediately to a specialist multidisciplinary foot care team for immobilisation of the affected joint(s) and for long-term management of offloading to prevent ulceration.”

Summary

Charcot Arthropathy IS uncommon (1:500 people with diabetes)

Diagnosis is often initially delayed, but community education and awareness significantly reduces this

Poor diabetic control appears to be a prerequisite for CNA

Conclusion

Earlier recognition and treatment of C.N.A. translates into significantly faster healing & 3/12`s less time in casts!

(Charcot “Road shows” work!)

Our local surgical practice is conservative & reserved for feet with recurrent or non healing ulcers only

Outcome for both limb and life is NOT adversely affected.

Larger patient numbers are needed to be studied to ratify these findings and this will demand collaborative working e.g. CDUK
