Venous ulceration is relatively common affecting 1- 3% of the population;1,2 it is a treatable con- dition but chronicity or non-healing is com- monplace. Many patients will have a diffi- cult experience often because compression is little understood in practice and usage across the UK is generally inadequate with pockets of good practice across the country. This paper contends that UK guidance offers little hope of a therapeutic interven- tion for the complex or non-standard group; there is no ‘Plan B’ if the patient does not respond favourably to standard UK high compression. The authors present 2 patients that are examples of this issue and have observed that tall men require compression greater than the UK standard; unfortunately the provision of strong compression of >60 mmHg is not promoted within the UK. Variations in guidance The UK national guidance1 for the man- agement of venous ulceration is weekly compression therapy where high compres- sion is stated as being 23-35 mmHg; in practice clinicians and industry refer to meeting 40 mmHg at the gaiter. This is con- sidered gold standard therapy within the UK. However, there are international varia- tions3 and these are that compression is described as: i) mild <20 mmHg; ii) moder- ate 20-40 mmHg; iii) strong 40-60 mmHg; iv) very strong >60 mmHg. Specialist clinicians in the UK do not promote the use of compression above 40 mmHg; there is the assumption that this is already high compression and is the upper limit. With the exception of the authors own training materials, there is no evidence that even within specialist leg ulcer modules that compression above 40 mmHg is pro- moted; there is plenty of anecdotal evidence that the UK consensus is that the applica- tion of strong compression is simply too strong and is seen as too high a risk for gen- eral leg ulcer management. Clinicians are advised1 on the areas that need to be consid- ered when determining the strength of the compression therapy, such as ankle width, underlying arterial status or tolerance and pain management. The standard care is pro- moted and is considered key to the provi- sion of optimal care and a quality interven- tion. However this intervention assumes that patients are similar, require the same level of compression therapy for this to be effective and also that nursing intervention is also standard. This is clearly not the case. Also guidance states that there are a number of parameters (pain, arterial status) that can be reviewed in order to provide safe but reduced compression. However only in the presence of a larger ankle circumference is the clinician advised to increase the level of compression to accommodate this feature and thereby providing a higher sub-bandage pressure and thus a therapeutic intervention. When an ulcer fails to respond to compression therapy When the use of optimal compression therapy at around 35 mmHg is failing to heal the leg ulcer, the guidance for the clini- cian is to use advanced dressings. If the compression therapy is not being tolerated by the patient, the guidance is to increase compression tolerance through patient edu- cation and adjustment and/or reduction of the compression level; there is the underly- ing belief that light compression is better than nothing. There is no guidance to review the therapeutic value of this potent intervention. It is not routine practice to question whether the standard high com- pression is actually adequate for that patient. There is no recommendation that improving the bandaging technique or con- sistency of intervention may increase its efficacy or tolerance; conversely patient experience would recognise the wide varia- tions in application techniques. There is thus no suggestion that the patient may ben- efit from a higher level of compression. Correspondence: Alison Hopkins, Accelerate CIC, Mile End Hospital, Bancroft Road, London E1 4DG, UK.

No n c om me rci al us e o nly Conference presentation [Veins and Lymphatics 2017; 6:6630] [page 17] The UK picture There is a growing gap between the the- ory of compression therapy as a clinical intervention and the UK practice of applica- tion. Compression is increasingly being taught as a task and not as a therapeutic intervention, often due to workforce capac- ity issues and the lack of available time for adequate training. The association of poor compression use with limb amputation has led to a risk averse approach to compression use and a culture of fear within nursing. This has meant a reduction in use of standard com- pression of 40 mmHg and a promotion of light or reduced compression in the UK; this can only lead to an increasing number of patients receiving inadequate compres- sion therapy and there is certainly enough anecdotal evidence to support this. The default to light compression is becoming the norm in clinical practice; a recent report of a leg ulcer audit found that of those who would benefit from compres- sion therapy, 16% were in high compression and 30% were in light compression.4 Figure 1 demonstrates the growing use of reduced compression within one well known multi- layer compression regime that has two ver- sions: standard high compression and a reduced or light compression. It appears that the introduction of the light compres- sion version was in response to nursing requests and the belief that patients do not tolerate high compression therapy. This assumption needs to be challenged. The authors and those clinicians who attend the ICC would refute this, noting that lack of patient tolerance is predominantly down to nursing technique, skill and knowledge of this potent therapy. The impact of non-therapeutic care is significant, resulting in poor oedema and exudate management in both leg ulcers and lymphorrhea; alongside this escalation of light compression we are seeing an increase in spend on extra-large superabsorbent dressings (a pad size greater than 15x15 cm) that simply absorbs this unmanaged exudate (Figure 2). Unfortunately admis- sion for cellulitis due to erosive or leg ulcer- ation are common. The impact of height UK guidance1 does not consider the impact of height on the level of compres- sion a patient requires for it to be therapeu- tic. This paper contends that tall men are a group of patients who do not respond to standard compression but experience a destructive response to its use (Figure 3). It is clear that hydrostatic pressure increases with height and that ordinarily 60-90 mmHg is required to narrow and occlude the veins. It is likely that a resting pressure of greater than 60 mmHg is thus required for vein occlusion in taller men. However, in the UK where multicomponent elastic Figure 3. Inelastic multilayer regime.

John and Geoff were referred to the author’s Treatment Centre for assessment following significant interventions from Dermatology and Vascular departments (Table 1). Their experience of cycles of improvement, deterioration, referral to vari- ous clinicians and query over their diagno- sis all took its toll on their lives. Their jour- neys and the impact of sustained very strong compression has led us to question the gaps in current UK guidance. It is the authors’ observation that the standard high compression,1 in the presence of height greater than 180 cm, acted as reduced or light compression; this generat- ed a destructive cycle of uncontrolled oede- ma, causing exudate and further erosions, additional pain and lack of tolerance for an ineffective regime. The patient’s pain also caused concern and the nurses reduced the level of compression further by applying light compression regimes. As described previously, guidelines advise the clinicians to seek alternative diagnosis or treatments; unfortunately these simply prolonged the patient’s deterioration and intractable pain. The clinical goal was to increase the level of compression to therapeutic levels alongside the provision of adequate analge- sia; an inelastic multilayer regime was used. This ensured that the hydrostatic nature of the ulceration or functional venous disease was managed, delivering circa 60 mmHg resting pressures at B1 level (Figure 3) and towards 70 mmHg working pressure. This approach led to healing without any addi- tional medical interventions; management was mostly a straightforward therapeutic task once the correct level of compression was reached. It is also important to note that this strong compression helped to reduce the pain despite the fear that this would exacerbate it; their experience was that their legs felt relief at the extra stiffness this regime provided, creating confidence in this approach (Figures 4-7). Conclusions This brief paper has identified some of the inadequacies of the current UK guid- ance on the management of venous ulcers namely what constitutes high compression and the limited advice for a non-standard patient. Guidelines and current UK educa- tion promote a risk aversion approach there- by limiting the treatment options for the most complex of patients. Figure 5.

No n c om me rci al us e o nly Conference presentation [Veins and Lymphatics 2017; 6:6630] [page 19] This paper introduces 2 patients for whom their destructive ulceration was reversed using extra high or strong com- pression, an approach that would be consid- ered dangerous in the UK. The authors con- tend that strong compression addresses the larger hydrostatic column in taller people. However, it is unclear whether bandages also behave differently in tall people. The use of light compression is on the increase in the UK and this can only have a detrimental impact on patients’ lives, the nursing workforce and the health economy. Clinicians in the UK and the ICC need to critique the current status of leg ulcer man- agement and promote the international con- sensus opinion of what constitutes high and thus therapeutic compression. Learning points - Clinicians in the UK need to question the level of sub-bandage pressure required in the non-healing group. - That taller patients require strong or very strong compression and this is above the UK recommendations. - That contrary to popular belief, strong compression can significantly reduce pain in the larger limb.
