LIMPRINT in Australia

Background and study objective: Australia was one of nine participating countries in the epidemiology Phase II LIMPRINT project to determine the number of people with chronic oedema in local health services. Methods and results: Data collection occurred through questionnaire-based interviews and clinical assessment with provided LIMPRINT tools. Four different types of services across three states in Australia participated. A total of 222 adults participated with an age range from 22 to 102 years, and 60% were female. Site 1 included three residential care facilities (54% of participants had swelling), site 2 was community delivered aged care services (24% of participants had swelling), site 3 was a hospital setting (facility-based prevalence study) (28% of participants had swelling) and site 4 was a wound treatment centre (specific patient population) (100% of participants had swelling). Of those with chronic oedema or secondary lymphoedema 93% were not related to cancer, the lower limbs were affected in 51% of cases and 18% of participants with swelling reported one or more episodes of cellulitis in the previous year. Wounds were identified in 47% (n=105) of all participants with more than half of those with wounds coming from the dedicated wound clinic. Leg/foot ulcer was the most common type of wound (65% n=68). Conclusion: Distances between services, lack of specialised services and various state funding models contribute to inequities in CO treatment. Understanding the high number of non-cancer related chronic oedema presentations will assist health services to provide timely, effective care and improve referral pathways

Prevalence and Impact of Chronic Edema in Bariatric Patients: A LIMPRINT Study

Background: Chronic edema (CO) is a complex condition, arising from different factors, including immobility and obesity. Edema and obesity can have a significant impact on quality of life of patients and their families. Understanding how to manage edema in obese patients is an increasing challenge for both patients and clinicians. As effective treatment options are limited for this population, it is more cost-effective for patients to lose weight before starting treatment. When patients cannot maintain weight loss, one option is to have bariatric surgery.This study was part of LIMPRINT: Lymphedema IMpact and PRevalence INTernational, a study with the aim of identifying the prevalence and impact of CO in different countries and health care settings.Study Purpose: To evaluate the prevalence and impact of CO among patients in a United Kingdom bariatric surgical service.Methods and Results: The gold standard pitting test assessed the presence of edema. General (EuroQOL-5 Dimensions [EQ-5D], RAND 36-Item Short Form Health Survey, Version 1.0 [SF-36], Generalized Anxiety Disorder 7-Item Scale [GAD-7] and Patient Health Questionnaire–9 [PHQ-9]), and edema-specific (Lymphedema Quality of Life [LYMQOL]) quality-of-life questionnaires were used to evaluate impact of edema.The prevalence of edema was 52.1% (25 of 48 participants had edema), potentially linked to obesity, immobility, and medications. Most participants had International Society of Lymphology (ISL) Stage I edema. There were no statistically significant differences between the quality of life of participants with and without edema. However, comparing SF-36 results and normative population data indicated that quality of life was much lower than those in the normative population.Conclusions: This study highlights the high prevalence of edema and low quality of life of this bariatric population.

Inter-rater reliability of the AFTD-pitting test among elderly patients in a long-term medical facility

BACKGROUND and AIM: The pitting test has been reported in various methods as a standard for evaluating chronic oedema, but a unified method has not been determined. This makes it difficult to accurately specify the prevalence of oedema. The present study aimed to evaluate inter-rater reliability of the AFTD-pitting test, which included 4 factors: Anatomical locations of oedema; Force required to pit; the amount of Time; and the Definition of oedema. The present study is the first stage of an international epidemiological study of chronic oedema.METHODS: This cross-sectional observational study was performed at a long-term care hospital in Ishikawa Prefecture, Japan. The inter-rater reliability of the pitting test for evaluating oedema using the AFTD-pitting test was tested for 34 locations on the body, with 10 seconds of pitting with a similar force to that of the reference rater and assessed using the modified Fukazawa method. One reference rater and four raters evaluated oedema in five patients. Then, the agreement rate and Cohen-s kappa coefficient were calculated.RESULTS: All protocols were completed by four raters for five bedridden patients. Agreement among the four raters was high, at >0.85, and the kappa coefficient showed almost perfect, moderate, and fair agreement for one (0.81), four (0.51-0.60) rater, respectively.CONCLUSION: The inter-rater reliability of four nurses who applied the AFTD-pitting test was high, and the kappa coefficient showed at least fair agreement. Therefore, the AFTD-pitting test is a useful method to assess whole-body chronic oedema

LIMPRINT: the UK experience - subjective control of swelling in patients attending specialist lymphedema services

Background and study design: This study was undertaken as part of the UK LIMPRINT international study to determine the number of people with chronic oedema and its impact on health services. Overall 7436 with chronic oedema (CO) were recruited in the main UK study from a range of health settings. Methods and results: Subjective control of arm and leg chronic oedema (CO) was defined for patients attending three Lymphoedema services in the UK. Of the total available in the UK dataset 5165 (69.4%)/ 7436(100%) of participants were included. Reasons for exclusions included the following: lack of information (1669), having both arm and leg swelling (272), lack of description of control (5) and professional inability to decide whether CO was controlled (325). Arm swelling occurred in 953 (18.5%), with leg CO in 4212 (81.5%). Poor control was found in 1430 (27.7%) and good control in 3735 (72.3%). Control of arm swelling was worse in men and control increased overall in those aged over 45 years. In contrast control of CO worsened in those with leg CO with increasing age and multiple co-morbidities. Obesity and cellulitis, particularly an episode in the last year were associated with poor control. Independent risk factors for arm CO were obesity, neurological disease and cellulitis in the last year and for leg CO: obesity, poor mobility, heart disease, presence of a wound, cellulitis in the last year and duration of swelling. Conclusion: Control of CO within specialised centres is complex due to sociodemographic and clinical comorbidities

Estimation of the prevalence of lymphoedema/chronic oedema in acute hospital in-patients

Background: To estimate the prevalence of lymphoedema/chronic oedema and wounds in acute hospital in-patients in 5 different countries. Method: A point-prevalence study was carried out during working day periods in six general hospitals in four countries (Denmark, France, United Kingdom, Australia) and one hospital oncology in-patient unit in one other country (Ireland). The study used validated clinical tools for the assessment and collection of data. Data were collected by expert clinicians through interviews and physical examination of the patients present in the wards. Results: A total of 1905 patients could be included and investigated among the 3041 total bed occupancy in the seven hospitals. Lymphoedema/chronic oedema was present in 723 of them (38%). Main risk factors associated with chronic oedema were age, morbid obesity and heart failure as well as chair bound immobility and neurological deficiency. History of cellulitis was frequent in patients with chronic oedema and wounds (24.8%), chronic oedema alone (14.1%) as compared to the 1.5% prevalence in patients without chronic oedema. Conclusion: Lymphoedema/chronic oedema is very frequent in patients hospitalized in hospital acute wards. It is strongly associated with obesity, venous insufficiency and heart failure. Our results strongly suggest a hidden health care burden and cost linked to chronic oedema independently of chronic wounds

Patient decision‐making and regret in pilonidal sinus surgery: a mixed‐methods study

Aim Little is known about optimal management strategies for pilonidal sinus disease (PSD). We conducted a mixed‐methods study to understand why patients make, and sometimes regret, treatment decisions. Method We conducted longitudinal semi‐structured interviews at the time of surgery and 6 months later with 20 patients from 13 UK hospitals. Framework analysis was performed, and themes were mapped to (1) the coping in deliberation framework and (2) an acceptability framework. Results were triangulated with those from structured survey instruments evaluating shared decision‐making (SDM, best = 9) at baseline and decision regret (DR, most regret = 100) at 6 months. Results Nine of 20 patients were not offered a choice of treatment, but this was not necessarily seen as negative (SDM median 4; range 2–4). Factors that influenced decision‐making included previous experience and anticipated recovery time. Median (range) DR was 5 (0–50). Those with the highest DR (scores 40–50) were, paradoxically, also amongst the highest scores on SDM (scores 4). Burden of wound care and the disparity between anticipated and actual recovery time were the main reasons for decision regret. Conclusion To minimize regret about surgical decisions, people with PSD need better information about the burden of wound care and the risks of recurrence associated with different surgical approaches

Prevalence and risk factors for chronic edema in U.K. community nursing services

Background and study design: Chronic edema (CO) is believed to be a major clinical problem within community nursing services in the UK. This study was undertaken as part of the LIMPRINT international study to determine the number of people with chronic oedema and its impact on health services. Methods and Results: Three urban based community nursing services participated in the UK with prospective evaluation over 4 weeks of all patients receiving nursing care using a questionnaire-based interview and clinical assessment using the LIMPRINT tools. Of the total 2,541 assessed 1,440 (56.7%) were considered to have CO, comprising Leicester City (768/ 1298 (59.2%), Nottingham West (124/ 181 (68.5%)) and Nottingham City (548/1062 (51.6%)). The mean age for women with CO was 78.6 (SD 12.8) years and for men 72.9 (SD14.5). More patients with CO suffered from diabetes (32.1% versus 27.9%, p=0.027), heart failure/ ischaemic heart disease (27.3% versus 14.0%, p<0.001) and peripheral arterial occlusive disease (5.5% versus 1.9%, p<0.001). By far the greatest association was with the presence of a wound (73.6% versus 37.9%, p<0.001). Cellulitis affected 628 (24.7%) and 688 (47.8%) had a concurrent leg ulcer. Rates of reduced mobility (71.6% versus 61.9%) and obesity were higher in those with CO. Six independent factors associated with chronic oedema were service location, age, ethnicity, obesity, heart failure and the presence of a wound. Conclusion: Chronic oedema is a major and growing health care problem within primary care that has been previously unrecognised and requires effective service provision
