Timetohealing
A key theme in most studies are high costs
associated with extended time to healing for
hard-to-heal wounds. Most commonly, the
size and duration of ulcer have been related
to outcome
146,147
and increased resource
utilisation.

A study by Tennvall et al.
148
confirmed that leg ulcers with an area of ≥ 10cm
2
and of longer duration (≥ 6 months) are the
most expensive. The cost, for example, of
treatment for a venous leg ulcer of less then
6 months in Sweden was estimated as €1827
(EUR) compared with €2585 for an ulcer of
greater then 6 months’ duration.

homecaresetting
Many health-economic studies in non-healing
wounds have focused on reduction in hospital stay
and treatment at hospital based specialist clinics.
However, a substantial number of resources are used
in outpatient facilities in primary care/home care.
When analysed according to care setting, home
health care accounted for the largest proportion
(48%) of the total cost of treating venous leg
ulcers in the USA.
141
A study in the UK calculated
that, in 2000, the mean annual cost per patient
for treatment at a leg ulcer clinic was €1205 and
by community nurses was €2135.
150
The finding
that home health care accounts for a significant
proportion of the total medical costs suggests that
promotion of high-quality care based in outpatient
clinics appears likely to improve cost efficiency. This
can be illustrated by a Swedish study in primary
care, where a system for early diagnosis of lower
leg ulcers and a strategy to reduce frequency of
dressings changes resulted in a substantial reduction
in resources used and economic cost.

These studies suggest the importance of organisation
in wound care, as well as coordination of treatment
strategies, to achieve an optimal care, both with
regard to outcome and cost.
the health economy
of debridement
Debridement is considered an essential part of
wound management, but the evidence supporting
debridement as a primary treatment regimen to
improve healing is sparse. The evidence primarily
consists of self reporting from treating physicians
and post hoc analysis of RCTs. As a consequence,
the health economic data specifically related to
debridement techniques are limited.
The literature listed in Table 5 covers the
identified studies including a cost-effectiveness
analysis of selected debridement techniques.
Need for studies on the cost-
effectiveness of debridement
Evidence, including health economic data, will
become increasingly important in a situation
where the impact of non-healing wounds on
society, as well as on the individual, is clarified and
the resources of the health-care system are scarce.
For approval of new treatment strategies these data
may become mandatory in many countries.
However, differences in reimbursement
procedures, health-care organisation, salaries
of staff members and facilities available in the
various European countries, make it difficult to
define clear-cut recommendations with regard to
health economics. Furthermore, methodological
difficulties, which are seen in the existing studies,
demonstrate a need to increase the knowledge
about economic evaluation with wound
management in general. An overview of the
methods of economic evaluation is included in
the EWMA Document Outcomes in controlled and
comparative studies on non-healing wounds.
