Changes in Lymphoedema-specific Patient Reported Outcome Measures using LYMPROM© |
The effect Intermittent Pneumatic Compression (IPC) has on Lymphoedema-specific Patient Reported Outcome Measure (LYMPROM©) scores. LYMPROM© is a lymphoedema specific PROM that captures 13 outcomes covering physical, social and emotional health domains. LYMPROM© version 1.2 (26/03/2021) uses a scale where patients can report each item using a 0-10 score, where zero represents no impact and 10 represents extreme impact. A higher score reflects a worse outcome. Four of the items also include a 'not applicable response' option. At the end of LYMPROM© there is a free text box for patients to report descriptively on any other impact. |

The feasibility of recruiting 40 participants over 18 months to a study using IPC at home using screening and recruitment logs |
Recruitment phases with no more than 15 participants recruited at a time will be reported, with a total of 40 participants recruited within the expected study time frame (18 months) as captured using the screening and recruitment logs. |

The acceptability of using Intermittent Pneumatic Compression (IPC) at home for 12-weeks including self-reported use (frequency and dose) of IPC using participant completed diaries |
Participant compliance with daily use of IPC, as documented in the instruction manual, will be reviewed by self-report including the dose and frequency of IPC use as documented in the participant diary. Dose and frequency of use will be reported as percentages compared to protocol. |

Changes in number of cellulitis episodes, hospital admissions (including length of stay), antibiotic use and number of days off work due to cellulitis as reported using the study case report form |
Number of cellulitis episodes before the study and cellulitis recurrence during the study, including hospital admissions and length of stay, antibiotic use and number of days off work due to cellulitis. |

Changes in range of movement measures using the study case report form |
Range of movement will be assessed from 0 percent to 100 percent where a higher number indicates increased range of movement. |

Changes in skin condition before and after the study including assessments of skin appearance (soft, fibrosis, discoloured) and the presence / absence of ulcers / wounds, Stemmer's signs and pitting oedema using the study case report form |
Skin appearance, texture and tests will be evaluated using standardised assessments as per the study case report form. All items are measured as the presence or absence of the condition with descriptors used to evaluate further. |

Changes in excess limb volumes using LymcalcTM, which uses the cylindrical calculation for limb volume |
Limb volume is measured using standardised guidance within the study case report form (LymcalcTM which uses the cylindrical calculation). Using measurements taken at 4cm intervals for the affected and unaffected limb volumes are calculated and will be reported as changes from baseline to end of study (reported a mls and percent). |

Changes in lymphoedema staging / severity using the International Society of Lymphology (ISL) Staging of Lymphoedema |
Lymphoedema staging / severity scales are not validated and none has achieved international agreement, therefore the ISL Staging of Lymphoedema will be reported alongside two other scales in use. The ISL has five stages; from 0 (a latent lymphoedema or sub-clinical phase where swelling is not yet evident) to stage III (where elephantiac changes are observed / marked skin changes). Stage 1 represents the accumulation of oedema / swelling and is reversible e.g. swelling will resolve upon elevation though there may be some pitting oedema. There are two stage II differentiated by the presence / absence of pitting oedema. Neither will resolve upon elevation and the absence of pitting marks an advanced / late stage of lymphoedema with excess subcutaneous fat / fibrosis developing. |

Changes in lymphoedema staging / severity using the British Lymphology Society (BLS) Grouping of Lymphoedema |
Lymphoedema staging / severity scales are not validated and none has achieved international agreement, therefore the BLS Group of Lymphoedema will be reported alongside two other scales in use. The BLS Groups begin with zero (a latent but high risk of lymphoedema phase) to stage four (palliative / end of life). Group one represents early lymphoedema (present for less than three months) where the swelling may resolve upon elevation for example. Group two represents established uncomplicated lymphoedema which no longer resolves upon elevation. Group three reflects complex lymphoedema with skin changes. There are three further sub categories within group three differentiated by the number of limbs affected or the presence of midline lymphoedema. |

Changes in lymphoedema staging / severity using the Lymphoedema Wales Clinical Network (LWCN) Lymphoedema Severity Outcomes of Lymphoedema |
Lymphoedema staging / severity scales are not validated and none has achieved international agreement, therefore the LWCN Lymphoedema Severity Outcomes are reported alongside two other scales in use. This scale starts at one (at risk of lymphoedema but with no swelling at present). Outcome two represents mild lymphoedema with 5-10% difference in volumes (between affected and unaffected limbs). Outcome three represents moderate lymphoedema with 10-20% volume difference and four represents severe lymphoedema (21-49% volume difference). The final outcome is group five which has a further sub category to indicate the presence of a wound. Outcome five represents complex lymphoedema (more than or equal to 50% volume difference). This is the only scale to report separately on the presence of wounds. |

Changes in health-related quality of life using the EQ-5D-5L |
Changes in quality of life scores and quality adjusted life years Health-related quality of life will be measured using the five-level EuroQol Five Dimensions (EQ-5D-5L). It is a non-disease specific tool to report health-related quality of life. The EQ-5D-5L includes five dimensions and a visual analogue scale (EQ-VAS). Each of the five dimensions are each reported with five responses (from no problems, slight problems, moderate problems, severe problems, and extreme problems). The five dimensions are mobility, self-care, usual activities, pain / discomfort, and anxiety / depression. For each of the five dimensions a 5-digit health state profile can be produced. The VAS records self-perceived health on the present day using a vertical thermometer from 0 (worst imaginable health) to 100 (best imaginable health). |

Changes in work and activity as reported using the Work Productivity and Activity Impairment Questionnaire: Lymphoedema (WPAI-Lymphoedema) |
WPAI has six items, the first is a dichotomous item to denote if the individual is in paid employment. The remainder of items are used to report presenteeism / absenteeism, productive loss and activity impairment. WPAI: Lymphoedema scores are presented as percentages where higher numbers indicate greater impairment and less productivity. |
