Pinch graft skin transplantation for leg ulcers in primary care

Leg Ulcers and Pain: A Review

Leg ulcers are a common health problem. Ulcers of any etiology including venous ulcers may be very painful, but until recently, health professionals have not been good at recognizing or managing this type of pain. It is important to clarify the type, severity, and frequency of pain and to anticipate pain at dressing changes. The measurement of pain by the use of pain scales is very useful, particularly in assessing the efficacy of an intervention. Neuropathic pain and unusually painful ulcerations are discussed in this article.

Risk Factors for Delayed Healing and Recurrence of Chronic Venous Leg Ulcers—An Analysis of 1324 Legs

OBJECTIVE

Despite similar disease patterns and treatment, there is great variation in clinical outcome between venous ulcer patients. The aim of this study was to identify independent risk factors for venous ulcer healing and recurrence.

METHODS

Consecutive patients assessed by a specialist nurse-led leg ulcer service between January 1998 and July 2003 with an ABPI>0.85 were included in this study. Independent risk factors for healing and recurrence were identified from routinely assessed variables using a Cox regression proportional hazards model.

RESULTS

A total of 1324 legs in 1186 patients were studied. The 24-week healing rate was 76% and 1 year recurrence rate was 17% (Kaplan-Meier life table analysis). Patient age (p <0.001, HR per year 0.989, 95% CI 0.984-0.995) and ulcer chronicity (p =0.019, HR per month 0.996, 95% CI 0.993-0.999) were independent risk factors for delayed ulcer healing. Ulcer healing time (p <0.001, HR per week 1.016, 95% CI 1.007-1.026) and superficial venous reflux not treated with surgery (p =0.015, HR 2.218, 95% CI 1.166-4.218) were independent risk factors for ulcer recurrence.

CONCLUSIONS

Elderly patients with longstanding ulcers should be targeted for further research and may benefit from adjunctive treatments to improve clinical outcomes. Patients not treated with superficial venous surgery were at increased risk of leg ulcer recurrence.

Leg ulcers in patients with rheumatoid arthritis--a prospective study of aetiology, wound healing and pain reduction after pinch grafting

OBJECTIVE

To study the aetiology of leg ulcers in patients with rheumatoid arthritis (RA) and to study healing and pain relief after pinch grafting.

METHODS

Twenty patients with RA and leg ulcers were studied. Diagnosis of the ulcers was founded on the clinical picture and measurements of the ankle-brachial pressure index. To detect vasculitis, skin biopsies were taken for immunohistochemistry and histopathology. Pain severity was assessed pre- and post-operatively using a visual analogue scale.

RESULTS

Ten of the 20 patients had ulcers with multifactorial aetiology. Fifteen had signs of venous insufficiency, 11 had histopathological evidence of vasculitis, four had reduced arterial circulation and two patients had diabetes. Healing after pinch grafting was found in eight patients, all of whom had an ulcer area less than 15 cm(2). Eleven out of 18 patients had pain reduction after pinch grafting.

CONCLUSION

The causation of leg ulcers in patients with RA was found to be multifactorial, with vasculitis and venous insufficiency as the main determinants. Pinch grafting seems to be a good alternative to conservative treatment for minor leg ulcers for these patients, regarding both wound healing and pain relief.

Pinch grafting in hospital and primary care: a cost analysis

The cost of treating venous leg ulcers with pinch grafting was evaluated for 58 consecutive patients: 29 in hospital care and 29 in primary care. The mean age was 76.8 and 74.3 years and the mean ulcer size 15.1 and 13.5 cm2, respectively. The operation technique, pinch grafting, was the same for all patients but primary care patients were not immobilised postoperatively. Healing rate within 12 weeks was the same for patients in hospital care and primary care (31%). Treatment costs for one week pre-operatively and three weeks postoperatively amounted to 5109 Pounds per patient in hospital care and 870 Pounds per patient in primary care (p < 0.001), and the costs for one week pre-operatively and 12 weeks postoperatively were 6738 Pounds and 1806 Pounds, respectively (p < 0.001). Costs for patients whose ulcers healed within 12 weeks were 5552 Pounds for those receiving hospital care and 1676 Pounds for those receiving primary care (p < 0.001). Pinch grafting in primary care was shown to cost 3.3 to 5.9 times less, with the same healing outcome, than pinch grafting in hospital care.
