Assessment and Management of Venous Leg Ulcers<br />

Background Context<br />

Leg ulcer disease is typically cyclical and chronic, with periods of healing followed by recurrence.<br />

It is not uncommon for leg ulcers to persist for years, with recurrence rates as high as 76 percent<br />

within one year (Nelzen, Bergquist & Lindhagen, 1995). Leg ulcers are a major cause of morbidity,<br />

suffering and high health service costs. The negative impact on the sufferer’s quality of life is<br />

significant, as individuals may experience mobility loss, chronic pain, fear, anger, depression,<br />

and social isolation (Phillips, Stanton, Provan & Lew, 1994; Pieper, Szczepaniak & Templin, 2000; Price & Harding, 1996).<br />

International studies on leg ulcer prevalence from all etiologies have demonstrated rates of<br />

between 1 and 6 per 1, 000 population in Western countries (Baker, Stacy, Jopp-McKay & Thompson,<br />

1991; Callam, Ruckley, Harper & Dale, 1985; Cornwall, Dore & Lewis, 1986; Nelzen et al., 1995). A one-month<br />

prevalence study in one large Canadian region found a prevalence rate of 1.8 per 1,000 for<br />

the population over the age of 25 (Harrison, Graham, Friedberg, Lorimer & Vandervelde-Coke, 2001). The<br />

care of this population is compounded by the fact that the condition is highly associated with<br />

age, with the prevalence rate reported in the 2 percent range for those over age 65 (Callam et<br />

al., 1985; Cornwall et al., 1986). Reports on the percentage of lower limb ulcerations that result<br />

predominantly from a venous etiology range from 37 to 62 percent (Baker et al., 1991; Callam et<br />

al., 1985; Cornwall et al., 1986; Nelzen, Bergquist, Lindhagen & Halbrook, 1991; Nelzen et al., 1995). Some<br />

studies found venous leg ulcers had a longer duration and a higher recurrence rate than those<br />

of a non-venous etiology (Baker et al., 1991; Nelzen et al., 1995).<br />

Surveys have shown wide variation in the clinical management of leg ulcers. Numerous types<br />

of wound dressings, bandages and stocking are used in the treatment and prevention of<br />

recurrence (Lees & Lambert, 1992; Stevens, Franks & Harrington, 1997). In leg ulcer care, using treatments<br />

with known efficacy leads to improvements in both healing rates and quality of life for the leg ulcer<br />

sufferer (Cullum, Nelson, Fletcher & Sheldon, 2000; Franks et al., 1995a). Despite the evidence supporting<br />

effective leg ulcer management, many clients are not receiving this care (Harrison et al., 2001; Hickie,<br />

Ross & Bond, 1998).<br />

The cost of caring for individuals with leg ulcers is significant. Reports from the United<br />

Kingdom and France indicate that the cost of venous diseases of the leg accounts for 2 percent<br />

of their total national health budgets (Laing, 1992). One study in the UK estimated that district<br />

nurses spend as much as 30 to 50 percent of their time with clients in leg ulcer care (Lees &<br />

Lambert, 1992). Over 80 percent of the ongoing management of chronic wounds such as leg<br />

ulcers occurs mainly in the community (Callam et al., 1985; Lees & Lambert, 1992; Lindholm, Bjellerup,<br />

Christensen & Zederfeldt, 1992). As the prevalence of leg ulcers increases with age, the swell in the<br />

elderly population with the advance of the “boomer” generation, and an anticipated increment<br />

in longevity will result in higher resource demand for community leg ulcer care.
