All patients should be offered an Ankle Brachial Pressure Index (ABPI) assessment prior to commencement of any compression therapy, using a Doppler, by a clinician who has had the appropriate training. Applying a compression bandage to a limb that has arterial insufficiency could lead to pressure damage, limb ischaemia, and even amputation.
Before elastic hosiery can be dispensed, the product (including accessories), the length, quantity (single or pair), compression class, knit (circular or flat), and manufacturer must be specified by the prescriber.
Below knee stockings should be prescribed for all patients unless it is clearly indicated that thigh length would be of additional benefit.
For patients experiencing difficulty putting on class 3 hosiery, wearing a class 1 plus a class 2 stocking will provide the same level of support.
Occasionally, ready-made stockings are not suitable and custom-made stockings will be required, specific to the patient's individual measurements. Made-to-measure stocking sizes may be required due to irregular limb dimensions or if a correctly sized ready-made stocking cannot be obtained from leg measurements.
Made to measure hosiery and garments are for specialist prescribing only – consider the wide variety of sizes available in the formulary prior to referral for specialist assessment. State 'made to measure' on the prescription.
It is advised that compression hosiery be prescribed in 2 pairs every 6 to 12 months; one to wear, one to wash, as appropriate for type, frequency of change, and wear conditions.
Compression hosiery comes in a multitude of shapes, sizes and classification testing standards, such as BS (British Standard), RAL (German Institute for Quality Assurance and Certification), and AFNOR (French national standard organisation)
Please ensure that when prescribing Compression Hosiery that consideration is given to the amount of compression you wish to achieve for your patient, regardless of classification. The below tables will act as a guide to support the right choice for the patient, and reduce potential prescribing errors.
BS |
Pressure Applied |
Recommended Use |
Class I | 14 - 17 mmHg | Varicose veins, mild oedema |
Class II | 18 - 24 mmHg | Moderate / severe varicose veins, prevention of ulcer recurrence |
Class III | 25 - 35 mmHg | Gross varices, post-phlebitic limb, leg ulcer recurrence, lymphoedema |
RAL |
Pressure Applied |
Recommended Use |
Class I | 18 - 21 mmHg | Minor varicose veins, early varices during pregnancy, not suitable for oedema |
Class II | 23 - 32 mmHg |
Varicose veins with oedema, post-traumatic swelling,
significant varicose veins during pregnancy |
Class III | 34 - 46 mmHg |
Chronic venous insufficiency, secondary varicose veins,
extensive oedema, recurrence |
Class IV | >40 mmHg | Lymphoedema |
There are two methods of making compression hosiery/garments:
Circular knit garments have no seams. The knit is fine and garments are soft and stretchy making application easier. Circular knit garments may be particularly useful for low risk patients who develop oedema as a result of a range of venous conditions. This type of hosiery may cause the development of tight bands around the oedematous region, especially in patients with soft pitting oedema. However, patients who are concerned about the appearance of the garment may prefer the sheer look of these. Unisex compression socks may help with patient concordance.
Flat knit garments have a seam and are usually made to measure. These are available in unlimited shapes and sizes. They are particularly useful for patients with unusual shaped limbs and lymphoedema / lympho-venous disease. They are made up from inelastic fibres and control chronic oedema by their stiffness. They may be recommended for chronic oedema / lymphoedema due to their positive effect on lymphatics (firm compression hosiery / garments move the fluid through the tissue spaces, increasing lymph reabsorption and stimulation of the lymphatics).

Leg ulcer hosiery treatment kits, give compression bandage patients a hosiery alternative. Colloquially called Class 4, it has been designed to provide an alternative to standard 4-layer bandaging, with a use in maintenance therapy when higher compression levels are required.
No form of compression should be used without a full leg ulcer assessment, with Doppler, being undertaken.
Mainly for use for those patients with an Ankle Brachial Pressure Index (ABPI) of above 0.8 they could be considered for individuals with a slightly lower ABPI providing there are no other arterial signs. They can be used to facilitate healing in patients with normal shaped limbs and minimal oedema. However, advice should be sought from Tissue Viability.
Consideration needs to be given to the length of the leg if using a stocking that does not specify short or long. Take care when ordering to specify size and, where appropriate, length.
Choose patients that have a degree of dexterity and can use an application device or who have family who can help apply the hosiery on at least a twice-weekly basis.
Ensure that patients/carers understand the need for appropriate care of hosiery. Products may have different washing instructions; ensure that patients are aware of specific recommendations for the selected product.
These hosiery can be used for patients who continually have recurrent leg ulcers, and may offer improvements in ease of application.

As with other compression, holistic leg ulcer assessment, with Doppler and ABPI calculation, must be performed prior to use.
Specialist use only, consider referral to Tissue Viability for advice about fitting with Juxta CURES or Juxta Fit if unable to manage ulceration or oedema with compression bandaging or treatment hosiery. This garment may also be suitable for patients who wish to be self-caring but have moderate to high exudate levels or require some leg reshaping.

Hosiery applicators are designed to make it easier to apply and remove compression garments, with minimal to no disruption to limbs, especially for those with mobility problems.
